Heart development -I
The document summarizes the development of the cardiovascular system from early embryogenesis through formation of the mature heart structure. It describes how progenitor heart cells migrate to form heart fields which fuse to become bilateral heart tubes. Through cardiac looping, the heart tube folds upon itself and changes position within the embryo. The sinus venosus contributes to formation of the right atrium, while absorption of pulmonary veins forms the left atrium. Division of the atrioventricular canal and incorporation of various structures results in the differentiated four-chambered heart.

This document discusses the development of the heart during embryogenesis. It describes how the heart forms from a single tube that undergoes looping and septation to form the four-chambered heart. Critical periods of development are outlined for structures such as the atrial and ventricular septa. Common congenital heart defects that can occur due to abnormalities during development are also summarized, including their prevalence. Factors that influence normal heart development like neural crest cells and genetic patterning are also covered at a high level.
Cvs+embryology+part+i+ +a2+students+only
The cardiovascular system is the first system to function in the embryo, with circulation beginning in the third week of development. It develops from mesenchymal cells that form angiogenic cell clusters, then a horseshoe-shaped plexus of blood vessels. The anterior region becomes the cardiogenic area where the heart develops. The heart tube forms from bilateral cardiogenic cords and fuses into a single tube that elongates and loops to form the primitive heart. This develops dilations and constrictions that form the four early chambers - sinus venosus, atrium, ventricle and bulbus cordis. Septa then develop that partition the heart into right and left sides.
Embryology of heart
The document summarizes the development of the heart from the 3rd week of gestation. It describes how the heart forms from mesodermal cells that aggregate to form endothelial heart tubes. It then details the formation of the various septa within the heart including the interatrial septum (from the septum primum, intermedium, and secundum), interventricular septum (from the endocardial cushions fusing), and division of the atrioventricular canal. Endocardial cushions play an important role in septation and any defects can result in conditions like atrioventricular septal defects.
Conotruncal anamolies
The conotruncus comprises collectively two myocardial subsegments, the conus and the truncus.
Conus is the myocardial segment between ventricle and semi lunar valves which gives rise to sub arterial coni.
Truncus is the fibrous segment between semi lunar valves and aortic sac which gives rise to great arteries.
Embryology of heart
The heart develops from mesodermal cardiogenic fields on either side of the embryo that fuse to form a primitive heart tube. This tube undergoes looping to the right, forming the chambers. Partitioning forms the atrial and ventricular septa, separating the chambers. In fetal circulation, blood is shunted away from the lungs through openings like the foramen ovale and ductus arteriosus. At birth, these close as the lungs become functional and circulation assumes the postnatal pattern. Defects can occur if septation or closure of passages is incomplete, leading to congenital heart diseases.
Heart development i
The document provides lecture notes on heart development. It discusses:
1. The heart develops from cardiogenic mesoderm and neural crest cells that migrate to the cardiogenic region.
2. The heart develops through 5 stages: specification of cardiac precursors, migration and fusion to form a heart tube, looping of the heart tube, chamber formation, and septation/valve formation.
3. The heart tube partitions internally through formation of septa to divide the atria, ventricles, and outflow tract into left and right sides. This completes the development of the four-chambered heart.
Systemic venous anomalies
The document discusses the embryology and anomalies of the systemic venous system. It begins by describing the normal development of the veins in a 4 week old embryo, including the vitelline, umbilical, cardinal, subcardinal, supracardinal and azygos veins. It then summarizes several anomalies of the superior vena cava including bilateral superior vena cava with normal drainage, bilateral superior vena cava with an unroofed coronary sinus, absent right superior vena cava, and retroaortic innominate vein. Diagnostic features and clinical manifestations of these anomalies are provided.

Development of heart
This document summarizes the development of the heart and great vessels from the 3rd week of gestation. It describes how the primitive heart tube forms from fused endothelial tubes and develops grooves that divide it into chambers. As the heart grows, it rotates and twists into its final shape with the right ventricle anterior and left-sided chambers posterior. The aortic arches form six pairs of vessels that remodel into the great arteries. Finally, it briefly describes some common congenital heart abnormalities such as Tetralogy of Fallot.
Heart and lung development
This document summarizes the embryology of the human heart and lungs. It describes how the heart develops from two endocardial tubes that merge to form the primitive heart tube by the 22nd day. Septa then form to separate the atria and ventricles. The lungs develop from endoderm and mesoderm, with lung buds forming by week 5 and descending into the pleural cavities. Over several months, the lungs continue developing alveoli and surfactant production to prepare for respiration outside the womb.
Cvs i
The document discusses the development of the cardiovascular system from early embryogenesis through the 8th week. It describes how the heart begins as a single tube that undergoes folding and partitioning to form the four-chambered heart. Key events include formation of the trilaminar embryo and heart fields, development of the heart tube, partitioning of the tube into chambers by formation of septa, and shaping of the tube into its adult looping form by the 8th week of development. Abnormalities in these developmental processes can result in congenital heart defects.

Development of heart
This document summarizes the early development of the heart from formation of the cardiac tube to septation and looping. It discusses:
- How the cardiac progenitor cells form paired tubes that fuse to form the primitive heart tube by 22 days.
- The lineages that give rise to the left and right ventricles.
- How signaling molecules regulate morphogenesis and migration of cells.
- The process of cardiac looping around 22-24 days which brings the ventricles into left/right orientation.
- Septation of the atria, atrioventricular canal and ventricles between 26-30 days which divides the heart into four chambers.
Embryology of the heart
The document summarizes the development of the cardiovascular system from the 3rd week of gestation. Key events include:
- Endothelial strands appear in the cardiogenic mesoderm by week 3 and arrange to form two heart tubes, which unite by week 4.
- By week 5, the heart begins beating and blood flow starts. Septa begin forming in the atria, ventricles, outflow tracts, and atrioventricular canal.
- By week 7, the interventricular foramen closes and membranous septum forms. Valves in the heart also begin developing. Folding of the heart tube positions it in the thoracic cavity.
Cardiac embryology
The document summarizes the key steps in cardiac embryology:
1. The heart develops from mesoderm and appears in the third week as a linear heart tube that loops to the right.
2. Septa form to divide the heart into four chambers, with the atria separating in the fourth week and ventricles separating by the fifth week.
3. Valves develop from endocardial cushions that form in the atrioventricular canal and outflow tract.
4. The conducting system develops from pacemaker cells in the heart tube and sinus venosus.
Human Cardiac embryology - 전이경 교수
The document summarizes the development of the heart during embryogenesis. It discusses that the heart is the first functioning organ to develop in the embryo, starting to beat at 4 weeks of gestation. The critical periods of heart development are between 3-8 weeks. Common congenital heart defects develop during this period if abnormalities occur in septation, looping, or partitioning of the heart structures. The document provides details on the formation of the atrial and ventricular septa, conduction system, heart chambers and valves throughout the critical stages of heart development.
Development of heart
1. The heart develops from mesoderm in the cardiogenic area as two endothelial heart tubes that fuse to form a single tube. This tube undergoes looping to form the four chambers.
2. The heart chambers develop from the bulbus cordis, primitive ventricle, primitive atrium, and sinus venosus portions of the heart tube. Septa form to divide the atria and ventricles. Valves develop from endocardial cushions.
3. Congenital heart defects can occur due to abnormal septation, outflow tract defects, or abnormal looping and siting of the heart. Common defects include atrial and ventricular septal defects, tetralogy of Fallot, and
Development of heart finale copy
The heart develops from cardiac progenitor cells that migrate to the cardiogenic field and form blood islands that fuse to create the endothelial heart tube. The heart tube undergoes cardiac looping and septation to form the four-chambered heart. During septation, the atria, ventricles, and great arteries are partitioned. The aortic arches give rise to major blood vessels of the head and neck. By the end of the 7th week, septation is largely complete and the heart has transformed into a functional four-chambered pump.
Coronary circulation and fetal circulation
This document discusses the coronary circulation, which supplies blood to the heart muscle, and the fetal circulation. It defines these circulations and provides details on the major coronary arteries - the right and left coronary arteries.
The right coronary artery is smaller and supplies the right atrium, portions of both ventricles, and parts of the interventricular septum. The left coronary artery is larger and supplies the left atrium, most of the left ventricle, parts of the right ventricle, and portions of the interventricular septum. Blockages in these arteries can cause heart attacks. The document also discusses collateral circulation between the arteries that can open up if one gets blocked.
Embryology of heart and fetal circulation
The document summarizes the embryology and fetal circulation of the heart. It describes how the heart develops from a single tube into a four-chambered structure over the first 8 weeks of gestation. During this period, the circulatory system changes from receiving oxygenated blood directly from the placenta to pulmonary circulation after birth. The document then outlines several common congenital cardiac anomalies such as atrial and ventricular septal defects, transposition of the great vessels, and tetralogy of Fallot.
Manoja_Gullapalli_ug
This document discusses the anatomy and development of the atrial septum. It begins by describing how the heart tube forms in the embryo. It then explains how the atrial septum develops from three sources: the septum primum, septum intermedium, and septum secundum. The foramen ovale allows blood to pass from the right to left atrium in fetuses. After birth, pressures change and the foramen ovale closes. Failure of this closure results in an atrial septal defect. The document provides details on the normal features and types of congenital septal defects.
Heart development 2
1. The document discusses the embryonic development of the heart, including the septation of the common atrium and ventricle to form the four chambers.
2. Septation of the atria occurs through the septum primum and septum secundum, which divide the primitive atrium into the right and left atria.
3. Septation of the ventricles is accomplished by formation of the muscular interventricular septum, membranous interventricular septum, and conus septum, which separate the bulboventricular cavity into the right and left ventricles.
venous drainage of the lower limb
The document describes the anatomy of the venous system, including the superficial and deep venous systems. It discusses key veins like the great saphenous vein and lesser saphenous vein. It also covers the deep venous system and its connections. Congenital variations are addressed, such as double inferior vena cava. May-Thurner syndrome is described as a compression of the left common iliac vein. References are provided at the end.
Development of the heart
The heart begins developing in the third week of gestation from mesodermal cells that form the cardiac tube. This tube undergoes looping and partitioning to form the four chambers. Septa form between the atria and ventricles, dividing them into left and right sides. In fetal circulation, three shunts allow oxygenated blood from the placenta to bypass the lungs and mix with deoxygenated blood before returning to the placenta. After birth, closure of the shunts and changes in hemodynamics establish the postnatal circulation.
Development of heart iv
1. The document describes the development of primitive veins including the vitelline, umbilical, and cardinal veins.
2. It explains how the umbilical veins contribute to formation of the portal vein and ductus venosus. The vitelline veins form anastomoses and tributaries that contribute to the hepatic vasculature.
3. The cardinal veins give rise to major veins including the subclavian, inferior vena cava, and azygos system. Variations in regression of veins can result in anomalies such as double inferior vena cava.
Embryology powerpoints
The cardiovascular and lymphatic systems develop through the processes of vasculogenesis, angiogenesis and hematopoiesis during embryonic and fetal periods. Key events include the formation of the heart tube and chambers, development of blood vessels including the aortic arches and umbilical/vitelline vessels, and maturation of the lymphatic organs including the thymus and spleen. The document provides a detailed overview of the embryonic development of these two important organ systems.
Venous anatomy of the brain
The document discusses the venous anatomy of the brain. It describes the superficial and deep venous systems that drain the brain. The superficial system includes four drainage groups - the superior sagittal, sphenoidal, tentorial, and falcine groups. These groups drain into dural sinuses. The deep system includes ventricular veins that drain the lateral ventricles and cisternal veins that drain the basal cisterns. Key veins discussed include the internal cerebral veins, great vein, basal vein, and veins within the posterior fossa. Understanding the venous anatomy is important for surgical planning and radiological localization of lesions.

Anomalies of the systemic venous return.pptx
This document discusses anomalies of the systemic venous return. Some anomalies have little clinical significance while others can cause cyanosis. Preoperative knowledge of venous anomalies is important for surgery as they impact techniques like venous cannulation. Common anomalies include persistent left superior vena cava and interrupted inferior vena cava with azygous continuation. These anomalies are often associated with other congenital heart defects.
Development of heart
The development of the heart occurs in several key stages:
1. Angiogenic cell clusters form in the lateral plate mesoderm and proliferate to form the initial heart tube structure.
2. The heart tube fuses into a single tube and develops an inner endocardial layer and outer myocardial layer.
3. The heart tube loops from right to left, forming the basic four-chamber structure of the heart. Local expansions form the atria, ventricles, and outflow tracts.
4. Partitioning occurs - endocardial cushions form and divide the atria and ventricles, while ridges partition the outflow tracts into the aorta and pulmonary trunk. This
Development of superior venacava and azygous vein
The major veins of the early embryo are the vitelline vein, umbilical vein, and cardinal veins. The portal vein is formed from parts of the right and left vitelline veins. As development continues, the left horn of the sinus venosus and left hepatocardiac channel disappear. The left umbilical vein remains to carry blood from the placenta to the liver via the ductus venosus. The superior vena cava develops from the right common cardinal vein and right anterior cardinal vein. The azygos vein forms from the right azygos line and part of the right posterior cardinal vein.
Atrial septaum development and
1. The atrial septum normally develops between the 4th and 8th weeks of gestation through the formation of the septum primum and secundum.
2. Abnormal development can result in several types of atrial septal defects (ASDs), the most common being a secundum ASD located in the area of the fossa ovalis.
3. Rarer types include sinus venosus defects (above or below the oval fossa), coronary sinus defects, and ostium primum defects located at the atrioventricular junction. Each has distinct developmental features and associations.
Vascular anomalies chest
The document discusses various vascular anomalies of the chest that can occur due to abnormalities in the development of the aortic arch system and pulmonary veins in embryos. It describes conditions like double aortic arch where both arches encircle the trachea and esophagus, coarctation of the aorta where there is narrowing of the descending aorta, and total anomalous pulmonary venous return where the pulmonary veins drain into structures other than the left atrium. It also provides diagrams and links to further explain these different vascular anomalies.
Embryology of heart and lung
The document discusses the embryology of the heart and lungs. It describes how the heart develops from a primitive heart tube into its four-chambered structure through processes of looping, wedging, and septation of the atria and ventricles. The lungs develop as the lung buds derive blood from the splanchnic plexus and pulmonary veins grow towards them. Abnormalities during these developmental stages can result in various congenital heart defects.
8108803
The document summarizes the development of the cardiovascular system from the establishment of the primordial system through circulation changes after birth and discusses some common congenital defects. It describes how the initial endothelial tube networks fuse to form the heart and blood vessels by 4 weeks. It then details the morphogenesis and partitioning of the heart chambers, including the atria, ventricles, and truncus arteriosus. Finally, it briefly explains some common congenital defects like atrial and ventricular septal defects, patent ductus arteriosus, and tetralogy of Fallot.
Ventricular Septal Defects - A Review
Ventricular septal defects (VSDs) are congenital holes in the wall separating the left and right ventricles of the heart. Henri Roger first described VSDs in 1879. VSDs are classified based on their location, with the main types being membranous, muscular, inlet, and outlet. The size of the defect determines the severity, with smaller defects having little impact and larger defects causing significant left-to-right shunting of blood. Symptoms range from none with small defects to heart failure in infants with large defects. Treatment may involve monitoring for closure, surgery, or device closure depending on the size and impact of the defect.
venous anomalies Dr Nikhil.pptx
The cardiovascular system develops from the mesoderm. The cardiogenic field is established around 18-19 days and develops into a fully functional heart by 8 weeks. The venous system develops from the vitelline veins, umbilical veins, and cardinal veins. These veins drain different areas of the developing embryo and undergo remodeling to form the adult venous structures, including redirection of blood flow through the liver into the inferior vena cava. Variations and anomalies can occur during this complex developmental process.
Development of great veins and surgical importance
1. The document discusses the embryology of the great venous system, including the development of the cardinal veins, azygos system, and inferior vena cava.
2. During the fifth week of development, the major veins include the vitelline veins, umbilical veins, and cardinal veins. The cardinal veins drain the body and later form parts of the great veins.
3. Anomalies of the superior vena cava are described, including bilateral superior vena cavae with normal drainage, bilateral superior vena cavae with an unroofed coronary sinus, and absent right superior vena cava in visceroatrial situs solitus.
heart ppt.pptx
This document summarizes heart embryology and radiological anatomy. It describes how the heart develops from mesenchymal cell clusters that form the primitive heart tube. This tube undergoes looping and partitioning to form the four chambers. Endocardial cushions develop and divide the atrioventricular canal and outflow tract. The document then describes heart anatomy and landmarks seen on imaging modalities like ultrasound, CT and MRI. It details the structures of the atria, ventricles, valves and coronary arteries. Standard views used in echocardiography are also mentioned.
Atrial septal defect
Leonardo da Vinci was the first to document a true atrial septal defect in his writings. The document then describes the normal process of atrial septation during embryonic development and how defects can occur if this process is disrupted. It classifies the main types of atrial septal defects and describes the characteristics, causes and clinical implications of each. Ostium secundum defects are the most common type while sinus venosus and coronary sinus defects are less common. The pathophysiology of left-to-right shunting with an atrial septal defect is explained.
Cardiovascular System Development
The document summarizes cardiovascular embryology, including:
1. Heart development begins with the formation of the horseshoe-shaped pericardial cavity and single heart tube, which undergoes convolution to form the primitive 4-chambered heart.
2. Septation occurs through atrial septation, ventricular septation, and aorticopulmonary septation to separate the chambers.
3. Arteries develop from the aortic arches and dorsal aortae, while veins form from the vitelline veins, umbilical veins, and cardinal veins.
4. The fetal circulation differs from the adult circulation, with blood bypassing the lungs via the ductus arteriosus and

Double outlet right ventricle
Double outlet right ventricle (DORV) is a congenital heart defect where both the aorta and pulmonary artery arise completely or predominantly from the right ventricle. The key features include aortomitral discontinuity and two ventricular outflow tracts. DORV can be acyanotic or cyanotic depending on associated lesions. Surgical repair depends on the location of the ventricular septal defect and relationship of the great arteries. Long-term complications may include obstruction, regurgitation, arrhythmias, or sudden cardiac death.
Vena cava anatomy and variants
This document discusses the normal anatomy and development of the superior and inferior vena cavae as well as common congenital anomalies that can occur. It begins with a description of the typical anatomy of the superior and inferior vena cavae and their tributaries. It then explains the embryonic development of the major veins, including how the cardinal veins form and remodel into the adult venous structures. Finally, it outlines several important congenital anomalies including bilateral superior vena cavae, left-sided superior vena cava, retroaortic innominate vein, left inferior vena cava, azygos continuation of the inferior vena cava, and circumcaval anomalies. Recognition of these anomalies is important to
atio ventricular septal defects
This document discusses the embryology, anatomy, classifications, and associated anomalies of atrioventricular septal defects (AVSDs). It describes the embryologic development of endocardial cushions and septum that can lead to partial or complete AVSD. Partial AVSD involves a cleft in the anterior mitral valve leaflet while complete AVSD lacks fusion of endocardial cushions, forming a common atrioventricular valve. Complete AVSD is further classified and associated anomalies are discussed, including conotruncal defects, coronary anomalies, and ventricular disproportion. Valve abnormalities like double orifice, papillary muscle anomalies, and their implications are also summarized.
Av canal defect
This document discusses atrioventricular canal defects (AVSDs), including their embryogenesis and pathophysiology. It describes the anatomy and classification of partial and complete AVSDs. Partial AVSDs involve a primum atrial septal defect with two distinct but contiguous AV valves, while complete AVSDs have a single common AV valve. The embryogenesis of AVSDs involves faulty development of the endocardial cushions. The document provides detailed descriptions and images of the anatomy and features of partial and complete AVSDs. It discusses the clinical aspects of AVSDs including prevalence, association with Down syndrome, surgical repair outcomes, and lifelong surveillance needs.
Ebstein anomaly
Ebstein's anomaly is a rare congenital heart defect where the tricuspid valve does not form properly, causing the valve leaflets to adhere to the heart wall. This displaces the valve downward and causes the right ventricle to enlarge. Patients may experience cyanosis, murmurs, and arrhythmias. Diagnosis involves ECG showing enlarged right atria, chest x-ray showing cardiomegaly, and echocardiogram demonstrating the displaced valve leaflets and enlarged chambers. Severity is classified using indices like displacement of the septal leaflet. Treatment depends on symptoms but may involve surgery to repair or replace the valve.
Congenital anomalies of IVC
The document discusses the various types of congenital anomalies of the inferior vena cava that can occur during embryonic development. It describes 9 types of anomalies and provides diagrams to illustrate them. The anomalies result from variations in the regression of the embryonic posterior cardinal, subcardinal, and supracardinal veins that normally form the segments of the inferior vena cava. The document also provides details on the embryonic development of the normal inferior vena cava and how variations can lead to anomalous structures.

Breast cancer: Post menopausal endocrine therapy
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

Gene Expression System-viral gene delivery Mpharm(Pharamaceutics)
Gene therapy can be broadly defined as the transfer of genetic material to cure a disease or at least to improve the clinical status of a patient.
One of the basic concepts of gene therapy is to transform viruses into genetic shuttles, which will deliver the gene of interest into the target cells.
Safe methods have been devised to do this, using several viral and non-viral vectors.
In the future, this technique may allow doctors to treat a disorder by inserting a gene into a patient's cells instead of using drugs or surgery.
The biggest hurdle faced by medical research in gene therapy is the availability of effective gene-carrying vectors that meet all of the following criteria:
Protection of transgene or genetic cargo from degradative action of systemic and endonucleases,
Delivery of genetic material to the target site, i.e., either cell cytoplasm or nucleus,
Low potential of triggering unwanted immune responses or genotoxicity,
Economical and feasible availability for patients .
Viruses are naturally evolved vehicles that efficiently transfer their genes into host cells.
Choice of viral vector is dependent on gene transfer efficiency, capacity to carry foreign genes, toxicity, stability, immune responses towards viral antigens and potential viral recombination.
There are a wide variety of vectors used to deliver DNA or oligo nucleotides into mammalian cells, either in vitro or in vivo.
The most common vector system based on retroviruses, adenoviruses, herpes simplex viruses, adeno associated viruses.
PGx Analysis in VarSeq: A User’s Perspective
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

Pharmacology of Prostaglandins, Thromboxanes and Leukotrienes
This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.
biomechanics of running. Dr.dhwani.pptx
The biomechanics of running involves the study of the mechanical principles underlying running movements. It includes the analysis of the running gait cycle, which consists of the stance phase (foot contact to push-off) and the swing phase (foot lift-off to next contact). Key aspects include kinematics (joint angles and movements, stride length and frequency) and kinetics (forces involved in running, including ground reaction and muscle forces). Understanding these factors helps in improving running performance, optimizing technique, and preventing injuries.
