Gel electrophoresis
Gel electrophoresis is a method used to separate DNA strands by size using an electric current. DNA is extracted from an organism, amplified via PCR, and cut with restriction enzymes. The DNA is then dyed and placed in an agarose gel. An electric current is run through the gel from negative to positive, causing the smallest DNA fragments to move fastest and farthest. Gel electrophoresis is used in criminal cases, paternity testing, and diagnosing genetic diseases by creating a DNA fingerprint.

gel electrophoresis is technique which we used to separate or purify some macromolecules like DNA RNA & proteins.
Electrophoresis 1
Gel electrophoresis is a technique used to separate charged particles like DNA fragments by size. An electric current is applied to a gel, causing negatively charged DNA fragments to migrate towards the positive electrode. Smaller fragments travel further than larger ones. DNA is first digested with restriction enzymes to generate fragments of different lengths. The DNA fragments are then loaded into wells in an agarose or acrylamide gel submerged in buffer solution. As an electric current is applied, the fragments separate by size. After completion, the gel can be stained with dye and visualized under UV light to see the separated DNA bands. This allows analysis and recovery of specific DNA fragments.
DNA extraction.pptx
DNA extraction is a method used to purify DNA from a sample by separating it from other cellular components using physical and chemical techniques. It involves lysing cells and solubilizing the DNA using detergents and enzymes. Common extraction methods include organic extraction, non-organic extraction, and adsorption. DNA can then be extracted from various samples for purposes like genetic testing, forensic analysis, and body identification.

This allows proteins to be separated by size when run on a polyacrylamide gel with an electric current. It also summarizes Southern blotting for detecting DNA, Northern blotting for detecting RNA, and Western blotting for detecting proteins. All involve separating molecules, transferring them to a membrane, and using probes or antibodies to identify specific sequences or proteins. The techniques have applications in research, forensics, medicine and molecular biology.
Electrophorosis
Electrophoresis is a technique used to separate molecules like DNA, RNA, and proteins based on their size and charge. Charged molecules migrate through a gel when an electric current is applied. Smaller molecules move faster through the gel than larger ones. The document discusses the history of electrophoresis, principles of how it works, different types like agarose and polyacrylamide gel electrophoresis, preparation of gels, buffers used, running samples through the gel, and visualizing results by staining.
Electrophoresis 1
Electrophoresis is a technique used to separate charged molecules like proteins, nucleic acids, and amino acids. It works by migrating the molecules through a supportive medium like agarose gel or polyacrylamide gel under the influence of an electric field. Larger molecules migrate more slowly than smaller ones. Factors like electric field strength, net charge on the molecule, and temperature influence migration velocity. Electrophoresis is used to separate DNA fragments by size. DNA samples are loaded into wells and electrophoresed, with smaller fragments migrating farther than larger ones. The separated fragments can then be visualized under UV light after ethidium bromide staining. Two-dimensional electrophoresis separately resolves proteins by their isoelectric point and

Free amoebae
1) Amoebae are single-celled organisms that can change shape by extending and retracting pseudopods. They are found across eukaryotic life and include pathogens.
2) Well-known pathogenic amoebae that can infect humans include Naegleria fowleri which causes meningoencephalitis, Entamoeba histolytica which causes dysentery, and Acanthamoeba which can cause keratitis or granulomatous amoebic encephalitis.
3) Amoebae move using pseudopods, feed through phagocytosis or pinocytosis, and can form protective cysts. Their life cycles and pathogenesis depend
Enteric fever
Typhoid fever is a bacterial infection caused by Salmonella Typhi that spreads through contaminated food or water. It has varied symptoms over 4 stages including sustained high fever, abdominal pain, and delirium. Diagnosis involves blood or stool cultures and the Widal test. Treatment is with antibiotics like fluoroquinolones or cephalosporins. Prevention relies on sanitation, hygiene, and typhoid vaccines. Multidrug resistance is a growing problem requiring alternative treatments.
Filariasis
Filariasis is caused by thread-like parasitic roundworms that are spread by mosquitoes and black flies. The worms live in the lymphatic system and other parts of the body, and the females release microfilariae that circulate in the bloodstream. Over time, this can lead to elephantiasis with thickening of the skin. Diagnosis involves examining blood slides for microfilariae at specific times of day. Treatment includes medications that kill the microfilariae like diethylcarbamazine, ivermectin, and doxycycline. Controlling mosquitoes is also important for preventing the spread of filarial parasites.
Swine Flu
- Swine influenza, or swine flu, is caused by influenza viruses that normally infect pigs. It can sometimes be transmitted from pigs to humans.
- Symptoms in humans are similar to regular flu symptoms like fever, cough, and sore throat. It spreads when people with the virus cough or sneeze.
- Treatment involves antiviral drugs, which work best if started within two days of symptoms. Vaccines are also available to prevent swine flu.
Ebola virus
The document provides information on Ebola virus, including:
1. Ebola virus is classified in the genus Ebolavirus and family Filoviridae. There are 5 species that cause disease in humans, with Zaire ebolavirus having the highest fatality rate of up to 90%.
2. Ebola virus disease symptoms start suddenly and include fever, muscle pain, and headaches. Later symptoms include vomiting, diarrhea, and internal/external bleeding.
3. The virus is transmitted through contact with infected body fluids and tissue. Bats are believed to be the natural reservoir of the virus. There is no approved vaccine or treatment, though supportive care can increase survival.
Free radicles
Free radicals are molecules with unpaired electrons that are highly reactive. They are generated through oxidative metabolism and reactions involving oxygen. Common free radicals include superoxide, hydroxyl radicals, and lipid peroxyl radicals. While free radicals can cause damage to tissues, the body has antioxidant defenses like superoxide dismutase, catalase, glutathione peroxidase, and vitamins C and E that help neutralize free radicals. Antioxidants protect cells from the harmful effects of free radical formation and oxidative stress.
Eukar transcription
Gene expression in eukaryotes involves transcription of DNA in the nucleus, followed by RNA processing and transport of mRNA to the cytoplasm for translation. Eukaryotic genes contain both coding exons and non-coding introns. During transcription, RNA polymerase II binds promoters and transcription factors to initiate transcription. The primary transcript undergoes splicing to remove introns and join exons, producing mature mRNA for translation into protein.
Gene Expression in Eukaryotes
Gene expression in eukaryotes involves transcription of DNA in the nucleus, processing and export of mRNA, and translation of mRNA on ribosomes in the cytoplasm. Eukaryotic genes contain both coding exons and non-coding introns; the exons must be spliced together to form mRNA before translation. Three RNA polymerases transcribe different types of RNA in the nucleus, with RNA polymerase II responsible for mRNA and some small nuclear RNAs. Precise binding of transcription factors to promoter elements upstream of genes is required for transcription initiation by RNA polymerase II.
ELECTRON TRANSPORT AND OXIDATIVE PHOSPHORYLATION
The document summarizes electron transport and oxidative phosphorylation. It describes how electrons from NADH and FADH2 are transported via carriers in the mitochondrial electron transport system to oxygen, with energy released used to synthesize ATP. Protons are pumped from the mitochondrial matrix to the intermembrane space, building a proton gradient that drives ATP synthesis by ATP synthase as protons flow back into the matrix. This chemiosmotic coupling allows efficient conversion of electron potential energy to chemical energy in the form of ATP.
ELISA
The document discusses the enzyme-linked immunosorbent assay (ELISA), a biochemical technique used to detect antibodies, antigens, or other molecules in a liquid sample. ELISA uses antibodies and color changing enzymes to identify target molecules. It is a sensitive, quantitative, and widely used technique in medicine and research. There are different types of ELISA including competitive, sandwich, and indirect methods depending on the target molecule being detected.
Energy Balance
Energy balance occurs when energy intake from food matches energy expenditure by the body. Energy expenditure consists of basal metabolic rate (BMR), the energy required for basic body functions, thermic effect of activity and food, and adaptive thermogenesis. BMR accounts for 50-75% of total energy expenditure and can be estimated using formulas factoring in weight, height, age, and gender. Tracking energy intake and expenditure helps determine if a person has a surplus, deficit, or balance of calories.
Ethyl Glucuronide
Ethyl glucuronide (EtG) is a biomarker for detecting alcohol consumption between 1 day and 1 week. It is formed by conjugating ethanol with glucuronic acid in the liver. EtG can be measured in urine, blood, and hair samples and remains detectable for up to 90 hours after heavy drinking. Studies have found EtG to be a sensitive and specific marker of recent alcohol intake that helps address the need for a biomarker in the timeframe not covered by other alcohol markers. Liquid chromatography-mass spectrometry is commonly used to precisely measure EtG levels in various samples.
Electrophoresis
This document discusses electrophoresis, which separates charged compounds using an electric field. It moves negatively charged proteins in serum towards the anode at pH 8.6. Applications include separating serum proteins, lipoproteins, hemoglobin variants, and isoenzymes. Zone electrophoresis is commonly used and involves applying samples to a support medium like paper, cellulose acetate, or polyacrylamide gel. After separation, proteins are visualized through staining and quantified using densitometry. Serum protein electrophoresis is used to analyze the albumin and globulin percentages. Abnormal patterns can indicate conditions like multiple myeloma or liver cirrhosis.
Ecosinoid metabolism
This document discusses the metabolism of unsaturated fatty acids and eicosanoids. It notes that animals have limited ability to desaturate fatty acids and require certain polyunsaturated fatty acids from plants. These essential fatty acids give rise to eicosanoic acids that produce eicosanoids like prostaglandins and leukotrienes. The metabolism of unsaturated fatty acids involves desaturase and elongase enzyme systems. Deficiencies in essential fatty acids can cause growth and reproductive issues in rats.
Electophorosis
This document provides an overview of electrophoresis, including:
1. Electrophoresis uses the migration of charged solutes or particles in a liquid medium under the influence of an electric field. It is widely used to separate biological molecules like proteins.
2. Particles with different charge-to-mass ratios migrate at different rates depending on factors like their net charge, size, and the pH and strength of the buffer solution. Agarose gel and polyacrylamide gel electrophoresis are commonly used techniques.
3. The general procedure involves separating the particles in an electric field, staining to visualize the bands, then detecting and quantifying the separated fractions. Automated systems now allow high-throughput processing of
Cytokines in diseases
Cytokines are proteins that are involved in cell signaling and communication during immune responses and inflammation. They modulate processes like immune cell differentiation, activation of lymphocytes and phagocytes, and the development of adaptive immunity. Corticosteroids suppress immunity by blocking cytokine synthesis and release. Cytokines play roles in diseases like cancer, rheumatoid arthritis, and septic shock by regulating immune and inflammatory processes. They can be measured clinically to monitor certain conditions.
Cortisol assays & diagnostic laboratory procedures
This document discusses cortisol measurement and its importance in diagnosing conditions like Cushing's syndrome and Addison's disease. It describes the physiology of cortisol secretion and regulation by CRH and ACTH in the HPA axis. Methods for measuring cortisol in serum, urine, and saliva are also outlined, including their advantages and disadvantages. Total serum cortisol, 24-hour urinary free cortisol, and salivary free cortisol are the main tests discussed for assessing cortisol levels.
Colorimetry
Colorimetry is a common analytical technique used in clinical laboratories to estimate biochemical substances. It involves measuring the color intensity of a colored solution, which is proportional to the concentration of the colored substance. The solution is passed through a colorimeter, which measures the amount of light absorbed. Beer's law and Lambert's law describe how the absorption is related to concentration and path length. The colorimeter contains a light source, filter to select the wavelength, cuvette to hold the sample, and detector to convert light intensity to an electrical signal. Standards and blanks are used for calibration. Colorimetry is used to estimate many substances in blood, urine, and cerebrospinal fluid.
Chromatography
Chromatography is a technique used to separate and identify the components of a mixture. It works by allowing the molecules present in the mixture to distribute themselves between a stationary and a mobile medium. Molecules that spend most of their time in the mobile phase are carried along faster. Gas liquid chromatography uses an unreactive gas as the mobile phase flowing through a tube, with an involatile liquid held on particles of a solid support as the stationary phase. Thin layer chromatography uses a liquid as the mobile phase flowing past a thin layer of powder on a solid support, with substances less attracted to the solid or more soluble in the liquid moving faster up the plate.
Chromatography
Chromatography is a technique used to separate and identify components of mixtures using the principle of partition between two phases, a stationary phase and a mobile phase. There are several types including paper, thin layer, and gas-liquid chromatography. Gas-liquid chromatography involves passing a sample through a column containing a stationary liquid phase using an inert gas as the mobile phase, which separates the components into individual peaks that can be analyzed to identify substances.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
