Blood cell formation
Hematopoiesis is the process by which blood cells are produced throughout life from hematopoietic stem cells located in the bone marrow. It begins early in embryonic development in the yolk sac and later moves to the liver and spleen before full establishment in the bone marrow. In the bone marrow, hematopoietic stem cells differentiate into various blood cell types including red blood cells, white blood cells, and platelets to replenish the blood supply on a continuous basis. The rate of hematopoiesis is regulated by the body's needs to replace old or damaged blood cells.

Blood
1. Normoblasts are immature red blood cells that are similar in size to mature RBCs and stain almost the same as most ribosomes are lost and more hemoglobin accumulates.
2. Polychromatophilic erythrocytes or reticulocytes are formed when a normoblast loses its nucleus but still retains some ribosomes, giving it a pink-blue stained cytoplasm.
3. Basophilic and polychromatophilic erythroblasts are larger developing red blood cells where the nucleus is condensing and hemoglobin begins to accumulate in the cytoplasm, producing different staining patterns.

14 Blood
Blood transports vital substances like oxygen and nutrients throughout the body. It is composed of plasma and three main cell types - red blood cells, white blood cells, and platelets. Red blood cells are produced in the bone marrow and carry oxygen to tissues via hemoglobin. They circulate for about 120 days before being broken down. White blood cells help protect the body from disease. Platelets help the blood clot and stop bleeding from broken blood vessels. The blood also contains proteins, gases, and other nutrients.
Anaemia, Erythropoiesis
Anemias are caused by a low red blood cell (RBC) count or low hemoglobin in RBCs. There are three main types of anemia: hypoproliferative anemia caused by decreased RBC production; hemolytic anemia caused by increased RBC destruction; and aplastic anemia caused by rare damage to stem cells in the bone marrow. Hemolytic anemias specifically result from a shortened RBC lifespan, where the bone marrow cannot replace destroyed RBCs quickly enough. Membrane defects can also cause hemolytic anemia, such as hereditary spherocytosis caused by alpha or beta spectrin deficiencies, which results in spherical RBCs more vulnerable to spleen destruction.
Hematopiosis.pptx
The document summarizes hematopoiesis, the process of blood cell production. It notes that blood cells have short lifespans, ranging from a few days to 120 days for erythrocytes. The organ responsible for hematopoiesis changes with development - in embryos it is the yolk sac, in fetuses it is the liver and spleen, and in adults it is the bone marrow. The bone marrow contains pluripotent hematopoietic stem cells that can differentiate into all types of blood cells. Regulation of hematopoiesis involves cytokines, growth factors secreted by bone marrow stromal cells, as well as erythropoietin and thrombopoietin which stimulate red blood cell and platelet
Erythropoiesis
Erythropoiesis is the process where red blood cells are produced. It occurs in multiple stages starting with stem cells in the bone marrow that differentiate into erythroid progenitor cells and progress through normoblast stages as the cells take up hemoglobin and lose their nuclei to become reticulocytes and then mature red blood cells. Key regulators of erythropoiesis include erythropoietin, iron, vitamin B12 and folic acid which promote red blood cell production and maturation. Hypoxia is the main stimulant for increased erythropoietin secretion from the kidneys which then acts to accelerate the production of red blood cells from progenitor cells in the bone marrow.

Hematopoiesis production and Disorders.pptx
Hematopoiesis is the process by which blood cells are formed. It occurs primarily in the bone marrow, which is a spongy tissue found within the cavities of certain bones, such as the sternum, ribs, pelvis, and long bones. Hematopoiesis involves the differentiation and proliferation of hematopoietic stem cells (HSCs) into various types of blood cells.
Differentiation and Lineage Commitment:
HSCs can differentiate into two main lineages: the myeloid lineage and the lymphoid lineage.
Myeloid lineage: Gives rise to red blood cells (erythrocytes), platelets (thrombocytes), and white blood cells (leukocytes) such as granulocytes (neutrophils, eosinophils, and basophils) and monocytes.
Lymphoid lineage: Gives rise to lymphocytes, including T cells, B cells, and natural killer (NK) cells.
Proliferation and Maturation:
Once committed to a specific lineage, progenitor cells undergo proliferation and differentiation into mature blood cells. This process is tightly regulated by various growth factors, cytokines, and hormones.
Erythropoiesis: The process of erythrocyte (red blood cell) production.
Thrombopoiesis: The process of platelet production.
Granulopoiesis: The process of granulocyte (neutrophil, eosinophil, basophil) production.
Monocytopoiesis: The process of monocyte production.
Lymphopoiesis: The process of lymphocyte production.
Regulation:
Hematopoiesis is tightly regulated by various factors, including:
Growth factors and cytokines such as erythropoietin (EPO), thrombopoietin (TPO), granulocyte colony-stimulating factor (G-CSF), and interleukins.
Hormones such as cortisol, thyroid hormones, and sex hormones.
Microenvironmental signals within the bone marrow niche.
Migration and Circulation:
Once matured, blood cells are released into the bloodstream and circulate throughout the body, performing their respective functions. Red blood cells carry oxygen to tissues, white blood cells participate in the immune response, and platelets are involved in blood clotting.
Blood lecture 1
The document provides an overview of haematology and the components of blood. It discusses the three main types of blood cells - red blood cells, white blood cells, and platelets. It describes their functions and characteristics in detail. Key points covered include haematopoiesis, the formation of blood cells in the bone marrow, and the roles of different white blood cell types in immunity.
Red blood cell formation and fate of RBC
RBCs are formed through a process called erythropoiesis where hematopoietic stem cells in the bone marrow differentiate into red blood cells over 4 days. The kidney regulates RBC production by releasing erythropoietin in response to low blood oxygen levels. As RBCs age over 120 days, they are destroyed by macrophages in the spleen and liver, recycling the iron while the heme portion is broken down into bilirubin and excreted in the feces and urine.

Erythrocytes are red blood cells that transport oxygen. Leukocytes, or white blood cells, help fight infection. Granulocytes include neutrophils, eosinophils and basophils, while agranulocytes are lymphocytes and monocytes. Thrombocytes, also called platelets, are involved in blood clotting.

Compositionofblood 180821200502-180824141919
Blood is a connective tissue composed of plasma and cellular elements. Plasma is 55% of blood volume and contains water, proteins, nutrients, gases, and electrolytes. Red blood cells carry oxygen and carbon dioxide. White blood cells defend against pathogens and include granulocytes like neutrophils and agranulocytes like lymphocytes. Platelets help form blood clots to stop bleeding. The production of red blood cells, white blood cells, and platelets is regulated to maintain appropriate blood cell counts.

Watchara
Professor Watchara Kasinrerk is an immunologist who received his PhD in immunology from Austria. He researches monoclonal antibody production and application at Chiang Mai University. His lab produces monoclonal antibodies using various methods for characterizing leukocyte surface molecules and developing immunodiagnostic kits. Recently he developed a non-flow cytometric method for CD4+ T cell enumeration using a hematology analyzer, providing an alternative for HIV/AIDS monitoring in limited resource settings.
Blood agar
This study compared four different blood agar media for culturing Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus: 1) defibrinated horse blood agar, 2) defibrinated sheep blood agar, 3) citrated sheep blood agar, and 4) human blood agar. Colony growth was similar across all media. However, human blood agar showed substantially smaller colony sizes and poor or absent hemolysis. Citrated sheep blood agar is an acceptable alternative that maintains characteristic morphology and hemolysis, unlike human blood agar. Human blood agar is not recommended for isolation or antibiotic susceptibility testing.
Polycythemia
Polycythemia vera is a chronic myeloproliferative disorder characterized by increased red blood cell production which leads to thickened blood and risk of blood clots. Diagnosis is based on criteria including elevated red blood cell count and spleen enlargement. Treatment aims to reduce blood thickness and prevent clots through regular blood removal and medications to suppress bone marrow activity.
Hemopoisis
Hematopoiesis is the formation of blood cells from hematopoietic stem cells located in bone marrow. There are three main lineages - erythroid cells (red blood cells), lymphocytes (white blood cells involved in immunity), and myelocytes (other white blood cells). Hematopoietic stem cells self-renew and can differentiate into various mature blood cell types. Growth factors and cytokines regulate the proliferation, differentiation, and maturation of blood cell lineages, while transcription factors determine the specific lineages that cells develop into.
Hemopoiesis[med]
This document discusses hemopoiesis, the production of blood cells. It describes the stem cells and progenitor cells involved in blood cell production, including pluripotent stem cells that can differentiate into any blood cell type. The stages of red blood cell and white blood cell development are outlined. Hemopoiesis is regulated by growth factors and cytokines that influence proliferation, differentiation and maturation of blood cells. The key cell types and signaling molecules involved in hemopoiesis are identified.
Naturally acquired plasmodium knowlesi malaria in human, thailand[1]
1) A 38-year-old Thai man contracted Plasmodium knowlesi malaria after spending time in a forested area of southern Thailand near the Thai-Myanmar border.
2) Microscopic examination of blood smears showed malaria parasites consistent with P. malariae. However, PCR and sequencing of the small subunit rRNA and mitochondrial cytochrome b genes confirmed the species as P. knowlesi.
3) This is the first reported case of naturally acquired P. knowlesi malaria in humans in Thailand, indicating that wild primate populations may serve as reservoirs for simian malaria parasites capable of infecting humans.
typhoid
This document reports on six cases of haemolytic anemia that occurred during the course of typhoid fever. The incidence of haemolytic anemia in the reported typhoid cases was 4.6%. All six patients showed signs of anaemia and jaundice. Laboratory findings indicated increased bilirubin levels and urobilinogen in urine. The red blood cell fragility was increased in some cases. The effects of chloramphenicol and ACTH treatment are also discussed.
rprotein3
This document describes engineering a novel secretion signal (SS) that is capable of directing the secretion of recombinant proteins from both prokaryotes and eukaryotes. The researchers demonstrated secretion of fusion reporter proteins containing the SS in Escherichia coli, Saccharomyces cerevisiae and six different eukaryotic cell lines. They also showed estrogen-inducible secretion of fusion reporter proteins in six common eukaryotic cell lines. The SS allows flexible strategy for production and secretion of recombinant proteins in numerous hosts and rapid study of protein expression.
rprotein2
This document summarizes the expression of recombinant β-lactoglobulin (rBLG) in prokaryotic and eukaryotic cells. In Escherichia coli, rBLG was expressed with a pET26 vector and was found predominantly in a denatured form, even when expressed in the periplasm. In eukaryotic cells like COS-7 and mouse tibialis muscle, rBLG was expressed in its native conformation. The authors quantified rBLG expression using immunoassays that distinguish between native and denatured rBLG. They found higher expression levels and native folding of rBLG in eukaryotic systems compared to prokaryotic expression
rprotein1
This poster presentation compares the potentials and limitations of various prokaryotic and eukaryotic expression systems for recombinant protein production. It summarizes data on typical maximum specific growth rates, specific product formation rates, product concentrations, and volumetric productivities for E. coli, P. pastoris, and CHO cell expression systems. The data provide a basis for understanding the biological limitations of protein synthesis and secretion in different host systems and identifying opportunities to optimize current expression systems.

This document describes a study comparing eukaryotic and prokaryotic recombinant Lutheran blood group protein for antibody identification. Recombinant Lutheran proteins were generated from both eukaryotic HEK293 cells and prokaryotic E. coli. Both recombinant proteins proved equally effective at identifying anti-Lub antibodies in patient samples. The recombinant proteins could potentially replace rare red blood cells in identifying antibodies against high-frequency antigens, allowing for more routine identification.
recombinant_protein_handbook
The document provides guidance on amplifying and purifying recombinant proteins. It discusses choosing a host system, vectors, and fusion tags for recombinant protein expression and purification. Common host systems include bacteria, yeast, insect and mammalian cells. Vectors can be for non-fusion or fusion proteins. Common fusion tags are GST and polyhistidine, each with advantages and disadvantages. The document then provides detailed protocols for purifying GST and polyhistidine fusion proteins using affinity chromatography.
rprotein
This document summarizes recent applications of recombinant fusion proteins for tissue engineering. It discusses four main classes of recombinant fusion proteins: 1) Structure-based proteins like elastin-like polymers (ELPs) and silk-like polymers (SLPs) which can be designed to modulate mechanical properties and biodegradation. 2) Cell-bound growth factor fusion proteins which link growth factors like bFGF and EGF to promote cellular responses. 3) Hybrid systems combining recombinant proteins with synthetic polymers. 4) Cadherin-based fusion proteins which may be applicable for stem cell tissue engineering by facilitating cell-cell interactions. The document outlines examples of each type of fusion protein and their potential uses and advantages for tissue engineering applications.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
