VITAMIN B8 BIOTIN MUHAMMAD MUSTANSAR
Biotin is a water-soluble B-complex vitamin that acts as a coenzyme in the metabolism of fats and amino acids. It plays a role in various metabolic reactions involved in cell growth, fatty acid synthesis, and protein synthesis. Biotin deficiency is rare in humans but can result from consuming large amounts of raw egg whites due to the avidin protein binding to biotin and preventing its absorption. Mild deficiency symptoms include dermatitis, hair loss, and fatigue.
Vitamin A MUHAMMAD MUSTANSAR
Vitamin A has important roles in vision, cellular differentiation, and gene expression. It is found in two forms: pre-formed retinol in animal foods like liver, dairy, and fish; and pro-vitamin A carotenoids in brightly colored fruits and vegetables like carrots, sweet potatoes, and mangoes. An adequate intake of vitamin A is important for vision, epithelial cell health, reproduction, bone remodeling, growth, and resistance to infection. Deficiency can cause night blindness, dry eyes, and increased susceptibility to disease.
VITAMIN D MUHAMMAD MUSTANSAR
Vitamin D is an essential nutrient that promotes calcium absorption in the intestines and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone. It exists in two main forms, D2 (ergocalciferol) and D3 (cholecalciferol), and is obtained through exposure to sunlight, dietary intake of oily fish, eggs, and vitamin D fortified foods. The liver converts vitamin D to calcidiol which is then converted by the kidneys to calcitriol, the biologically active form, which regulates calcium and phosphate levels. Deficiencies can lead to rickets in children and osteomalacia in adults, characterized by soft, deformed bones and muscle weakness.
classification of VITAMINS MUHAMMAD MUSTANSAR
Vitamins are organic compounds that are essential micronutrients required by the body in small amounts. There are 13 types of vitamins that are classified as either fat-soluble or water-soluble. Vitamins act as cofactors for enzymes and help regulate metabolic processes. While the body cannot produce most vitamins, they must be obtained through dietary intake or supplements. Maintaining adequate vitamin levels is important for overall health and preventing deficiency diseases.
Vitamin B5 pantothenic acid MUHAMMAD MUSTANSAR
Vitamin B5, also known as pantothenic acid, forms part of coenzyme A which plays an important role in energy metabolism. It is essential for the formation of ATP from the breakdown of carbohydrates, proteins, fats, and alcohol. Pantothenic acid is used to synthesize coenzyme A, which transports carbon atoms within cells to form acetyl-CoA and related compounds for energy metabolism and biosynthesis of important compounds like fatty acids and cholesterol. Coenzyme A is also required for the formation of acetyl carrier protein needed for fatty acid synthesis.
Biotin ppt.
Biotin is a B vitamin that acts as a coenzyme in carbohydrate, protein, and lipid metabolism. It is essential for cell growth and DNA/RNA replication. Biotin deficiency can cause dermatitis, hair loss, and neuromuscular dysfunction with symptoms like scaly skin, rash, hypotonia, and depression. Good dietary sources of biotin include eggs, organ meats, nuts, dairy, and whole grains.
Folic acid
Folic acid is a B vitamin found in green leafy vegetables and whole grains. It is required for DNA synthesis and cell division. The biologically active form is tetrahydrofolate, which carries single carbon groups and is involved in reactions like purine synthesis. Deficiency can cause megaloblastic anemia during pregnancy or infancy due to impaired DNA synthesis. It is also associated with increased homocysteine levels and neural tube defects if deficiency occurs during pregnancy. While folic acid supplements can treat deficiency, they should not be given to cancer patients as it may increase abnormal cell growth and division.
Folic acid
This document discusses folic acid and vitamin B12. It describes:
1) Folic acid is present in vegetables and consists of three parts. It is involved in DNA synthesis and preventing cancer and heart disease.
2) Deficiencies can result from pregnancy, malabsorption, drugs that inhibit enzyme activity, and lack of vegetables in the diet. This leads to megaloblastic anemia.
3) Vitamin B12 contains cobalt and is only found in animal products. Deficiencies can result from gastric issues or lack of intrinsic factor leading to neurological problems like subacute combined degeneration of the spinal cord.

Lipid profile
This document provides information about lipid profiles and their normal ranges. It discusses how to collect and process blood specimens for lipid profiles. It then defines the components of a lipid profile including total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides, and VLDL cholesterol. For each component, it provides the normal ranges and clinical significance of abnormal levels. It also briefly discusses apolipoprotein B, phospholipids, chylomicrons, and factors that can increase or decrease their levels.
Introduction of biochemistry
Carbohydrates, lipids, proteins, and nucleic acids are the four major macromolecules that make up living things. Carbohydrates include sugars and starches and are used for energy storage. Lipids are composed of fatty acids and glycerol and function in energy storage, protection, and insulation. Proteins contain amino acids and perform a variety of functions including growth, energy production, and pH buffering. Nucleic acids like DNA and RNA contain nucleotides and store and transmit genetic information that directs cellular functions. These macromolecules are formed through dehydration synthesis and broken down through hydrolysis.
BIOCHEMISTRY OF LIPIDS
Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, and fat-soluble vitamins. They serve important functions like storing energy, signaling, and as structural components of cell membranes. The document defines lipids and discusses their chemistry, classifications, structures, and biological importance. Key points covered include that lipids are insoluble in water but soluble in organic solvents, and include triglycerides, fatty acids, and other compounds.
ECOSANOIDS
Eicosanoids are oxygenation products of arachidonic acid (AA), a polyunsaturated fatty acid found in animal and plant cell membranes. AA is released from membranes by phospholipase A2 and metabolized via either the cyclooxygenase pathway to form prostaglandins, prostacyclin, and thromboxanes, or the lipoxygenase pathway to form leukotrienes. These eicosanoids are involved in various physiological functions including inflammation, smooth muscle tone, blood coagulation, reproduction, and GI secretion. Clinical applications of prostaglandins include female and male reproductive health, inflammation and immunity, gastrointestinal, respiratory, musculoskeletal, cardiovascular, ocular health, and cancer.
ROS ANTIOXIDENTS
Aerobic organisms continuously produce reactive free radicals through respiration, metabolism and phagocytosis. Approximately 1-2% of oxygen consumed is converted into superoxide radicals by the respiratory chain, one of the main sources of free radicals in cells. While oxygen is necessary for life, its partial reduction can produce reactive oxygen species (ROS) that damage living systems. The body has multiple antioxidant defenses to combat ROS, including superoxide dismutase, catalase, glutathione peroxidase and vitamin C, which help convert ROS into less reactive species and protect biomolecules from oxidative damage.
LIPID CHEMISTRY
Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, and fat-soluble vitamins. They serve important functions like energy storage, signaling, and as structural components of cell membranes. The main classes of lipids are neutral fats/triglycerides (consisting of glycerol and fatty acids), phospholipids, and sterols. Fatty acids can be saturated or unsaturated, and polyunsaturated fatty acids like omega-3 and omega-6 are essential nutrients. Lipids are insoluble in water but soluble in organic solvents, and are an important energy source in animals and plants.
Carcinogen
This document discusses carcinogens and cancer. It defines cancer as abnormal cell growth that can invade other tissues and spread to other parts of the body. Carcinogens are substances that can cause cancer. Chemical carcinogens include aromatic hydrocarbons, aromatic amines, and chemicals containing epoxide, organohalogen, and nitroso groups. Carcinogens can damage DNA directly or require metabolic activation. Factors that influence cancer development include dose of exposure, lifestyle factors like smoking, and inherited conditions. Engineering controls, personal protective equipment, hygiene practices, and proper waste disposal can reduce exposure to carcinogens.
Infectious diseases
This document discusses the importance of breastfeeding for infant health and development. It reviews several studies that show breastfeeding reduces the risk of morbidity and mortality from various infectious diseases like diarrhea, otitis media, neonatal sepsis, and respiratory infections. However, in many societies false beliefs interfere with breastfeeding and infants are commonly given prelacteal feeds or mixed feeding instead of being exclusively breastfed. The purpose of the study described is to examine the patterns of infectious diseases in non-breastfed infants compared to breastfed infants admitted to the hospital.
Differences of plasma osmolarity
This document describes a study comparing plasma osmolarity in healthy breastfed and non-breastfed infants. The study included breastfed and non-breastfed infants between 1-6 months of age. Blood samples were collected and analyzed for various biomarkers including glucose, BUN, sodium, potassium, total protein, and albumin levels. Plasma osmolarity was then directly estimated and calculated based on biomarker levels. Results showed breastfed infants had significantly lower glucose, BUN, and plasma osmolarity levels compared to non-breastfed infants. The study concluded breastfeeding provides a lower solute load compared to formula feeding, resulting in lower plasma osmolarity in healthy breastfed infants.
Introdction of metabolism
1. Metabolism refers to the chemical processes that take place in living organisms to sustain life. It includes breaking down nutrients into smaller units and building up complex molecules.
2. Glucose, fats, and proteins are broken down through various pathways to ultimately form acetyl CoA, which enters the citric acid cycle to generate energy in the form of ATP. Less oxygen results in lactic acid formation from glucose.
3. The electron transport chain uses oxygen to convert products of the citric acid cycle into large amounts of ATP, the main energy currency of cells. Fatty acids yield more ATP than glucose due to their carbon-hydrogen bonds.
TRINITY COLLEGE ROBOTIC COMPETITION
The Tufts Robotics Club attended the Trinity College Fire Fighting Robot Contest where they won both the team and individual categories of the Olympiad tournament. This marked the club's fourth win since 2014. They competed in both the mechanical robot competition and trivia-based Olympiad. For the robot competition, Tufts engineered a robot that followed the right wall of the maze and used a fire extinguisher to put out a candle, navigating the maze faster than other teams. In the Olympiad, they demonstrated their strong theoretical engineering knowledge, with sophomore Faizan Muhammad winning individually. The success at this competition aims to attract new recruits to the club.
GLUCOSE TOLERANCE TEST
A glucose tolerance test (GTT) checks how the body metabolizes blood sugar levels over time. There are two main types: an oral GTT where glucose is ingested, and an intravenous GTT where glucose is injected. It is commonly used to screen for prediabetes and diabetes, especially in obese, pregnant, or high-risk individuals. The test involves fasting overnight, then drinking a glucose solution and having blood drawn over 3 hours to analyze the body's insulin response and how quickly glucose is cleared from the blood. Results are interpreted according to WHO criteria, with different glucose level thresholds indicating normal, prediabetes, or diabetes status.
Conference proceedings
This document summarizes a study that compares the performance of two state observers - a sliding mode observer with super-twisting algorithm (STSMO) and a high gain observer (HGO) - for estimating unmeasured states of a quadrotor UAV. The paper designs each observer and then applies a second order sliding mode control technique using the estimated states to control the quadrotor. Simulations show the performance of each observer under the same control scheme and perturbations. The study aims to compare the observers' characteristics for state estimation of the quadrotor system to determine the best observer for real-time applications given system uncertainties and noise.
social media useage
This study examined the usage of social media by students at the FJMU Lahore. A questionnaire was distributed to 415 students to gather data on their social media usage patterns and behaviors. The results found that 95.9% of students used social media daily, with 77% spending 1-2 hours per day on social media. Major purposes of usage were communication (94%) and entertainment (93%), though 46% also used it for studying. Students reported social media could waste time and distract from studies, but could also be useful for sharing medical videos, knowledge and study guidelines. The study concludes social media distracts students and encourages more non-educational activities, so students should utilize it more for academic purposes and limit entertainment usage

Lactation
This document discusses guidelines for drug use during lactation. It begins by outlining principles from the Quran and Hadith regarding breastfeeding. It then discusses anatomy related to lactation and hormonal regulation. Guidelines for chemotherapy during lactation emphasize using drugs with minimal infant exposure and avoiding unnecessary drugs. Several classes of drugs are discussed, identifying those that are generally safe to use during lactation like beta-blockers, thiazides, ACE inhibitors, warfarin, inhaled asthma medications, and corticosteroids. Drugs that should be avoided include phenobarbital, primodone, and clonazepam. The document also covers stimulants and inhibitors of lactation.
Biological oxidation
Cellular respiration is the process by which cells break down glucose and other organic molecules to obtain energy in the form of ATP. It occurs in three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. During glycolysis, glucose is broken down to form pyruvate in the cytoplasm. In the citric acid cycle, pyruvate enters the mitochondria and is further oxidized, producing NADH, FADH2, and ATP. During oxidative phosphorylation, electrons from NADH and FADH2 are passed through an electron transport chain in the mitochondrial inner membrane. Their energy is used to pump protons out of the matrix, establishing a proton gradient. ATP synthase uses this gradient to
