इज्जलोजी meaning
"इज्जलोजी" यह शब्द मुझे पूरी तरह स्पष्ट नहीं है। यह हिंदी, मराठी, या किसी अन्य भाषा का शब्द हो सकता है, लेकिन मुझे इसका सटीक अर्थ नहीं मिल रहा।
क्या आप थोड़ा और संदर्भ दे सकते हैं?
- क्या यह किसी विषय (subject) का नाम है?
- किस भाषा में यह शब्द आया?
- क्या यह "Ideology" (विचारधारा) या "Ecology" (पारिस्थितिकी) जैसे किसी अंग्रेज़ी शब्द का उच्चारण है?

Frameshift: insertion/deletion (shifts reading frame - thalassemia, Duchenne MD). Nonsense: creates premature stop codon (beta0-thalassemia). Silent: no amino acid change. Missense: different amino acid (HbS: Glu→Val). Splice site: abnormal splicing (beta+-thalassemia). Deletions (alpha-thalassemia). Mutagens: base analogs (5-BU), alkylating agents (nitrogen mustard - cancer), intercalating agents (ethidium bromide - frameshift), UV light (thymine dimers). DNA repair defects: xeroderma pigmentosum, Fanconi anemia."),

"section": "Vitamins, Minerals & Clinical Topics",
"color": TEAL,
"notes": [
("Water-soluble vitamins - Vitamin C (Ascorbic acid)",
"Functions: cofactor for hydroxylation reactions (prolyl and lysyl hydroxylase - collagen synthesis, dopamine beta-hydroxylase - catecholamine synthesis), antioxidant (regenerates Vitamin E, reduces Fe3+→Fe2+ for iron absorption), immunomodulation, carnitine synthesis. Deficiency: scurvy - defective collagen (perifollicular hemorrhage, bleeding gums, corkscrew hairs, poor wound healing, periosteal hemorrhage, Barlow disease in infants). Dietary sources: citrus fruits, tomatoes, peppers."),
("Iron metabolism",
"Absorption: Fe2+ (ferrous) absorbed in duodenum (DMT1), oxidized to Fe3+ by hephaestin. Fe3+ in blood bound to transferrin (2 Fe3+/molecule). Storage: ferritin (liver, spleen, bone marrow) + hemosiderin. Utilization: 70% in Hb, myoglobin, cytochromes, Fe-S proteins. Regulation: hepcidin (liver peptide, blocks ferroportin, key regulator of iron efflux). Iron deficiency anemia: microcytic hypochromic, low serum iron, low ferritin, high TIBC, high RDW. Hemochromatosis: HFE gene mutation, iron overload, bronze diabetes, cirrhosis, cardiac failure, hypogonadism."),
("Calcium and phosphate metabolism",
"Calcium homeostasis: PTH (increases serum Ca2+ - bone resorption, renal Ca2+ reabsorption, 1,25-OH2-D3 production), Calcitonin (decreases serum Ca2+ - osteoclast inhibition), Vitamin D (increases intestinal Ca2+ and PO4 absorption). Normal serum Ca2+ 8.5-10.5 mg/dL. Hypocalcemia: tetany (Chvostek, Trousseau signs), hypoparathyroidism, Vit D deficiency, hypomagnesemia. Hypercalcemia: hyperparathyroidism (commonest), malignancy (PTHrP), Vit D toxicity; stones, bones, groans, psychic moans. Phosphate: regulated by PTH (decreases reabsorption), FGF-23 (phosphatonin - decreases reabsorption)."),
("Plasma proteins",
"Albumin (35-50g/L, synthesized in liver, t1/2 20 days): oncotic pressure (main), transport (bilirubin, fatty acids, drugs, hormones, Ca2+), buffer, acute phase negative reactant. Decreased in: liver disease, nephrotic syndrome, malnutrition, chronic disease. Globulins: alpha1 (AAT, alpha1-acid glycoprotein), alpha2 (haptoglobin, ceruloplasmin, alpha2-macroglobulin), beta (transferrin, C3, fibrinogen, LDL), gamma (immunoglobulins). Acute phase proteins (increase in inflammation): CRP, fibrinogen, ferritin, haptoglobin, alpha1-antitrypsin, ceruloplasmin. Electrophoresis patterns: cirrhosis (low albumin, gamma elevation - beta-gamma bridging), multiple myeloma (M-spike in gamma)."),
("Diabetes mellitus - biochemical basis",
"Type 1: absolute insulin deficiency (autoimmune beta-cell destruction) → hyperglycemia (no GLUT4 in muscle/fat), increased gluconeogenesis, increased lipolysis (HSL uninhibited) → FFA → ketogenesis → DKA (anion gap metabolic acidosis, fruity breath, Kussmaul respiration). Type 2: insulin resistance + relative insulin deficiency → compensatory hyperinsulinemia → beta-cell exhaustion. Metabolic consequences: glycosylation of proteins (HbA1c - time-averaged glucose over 3 months, normal <5.7%), AGEs (advanced glycation end products - microvascular complications), polyol pathway (sorbitol accumulation in lens/nerves/retina - cataracts, neuropathy, retinopathy), protein kinase C activation. Diagnosis: fasting glucose ≥126 mg/dL, 2h OGTT ≥200, HbA1c ≥6.5%."),
("Antioxidants and free radical biochemistry",
"Free radicals: ROS (superoxide O2•-, hydroxyl OH•, H2O2) generated by mitochondrial ETC, phagocytes (NADPH oxidase), cytochrome P450. Damage: lipid peroxidation (chain reaction), protein oxidation, DNA oxidation (8-oxoguanine). Enzymatic antioxidants: SOD (superoxide dismutase - converts O2•- to H2O2), catalase (H2O2→H2O+O2), GSH peroxidase (needs glutathione, requires NADPH from HMP shunt - G6PD importance). Non-enzymatic: Vitamin E (lipid-soluble, chain-breaking antioxidant), Vitamin C (aqueous phase, regenerates Vit E), beta-carotene (quenches singlet O2), selenium (GSH peroxidase cofactor). Disease links: atherosclerosis, cancer, aging, reperfusion injury."),
("Tumor markers",
"Proteins/substances elevated in cancer, used for diagnosis, monitoring, screening. AFP (alpha-fetoprotein): hepatocellular carcinoma, germ cell tumors (>400ng/mL significant), elevated in pregnancy. CEA (carcinoembryonic antigen): colorectal cancer, monitoring recurrence. PSA (prostate specific antigen): prostate cancer screening (>4ng/mL). CA-125: ovarian cancer monitoring. CA 19-9: pancreatic cancer. CA 15-3: breast cancer monitoring. HCG: gestational trophoblastic disease, testicular germ cell tumors. LDH: lymphoma, testicular cancer (prognosis). Note: no marker is 100% specific/sensitive - used in context of clinical findings."),
("Nucleotide synthesis - pyrimidine pathway",
"De novo: starts from carbamoyl phosphate (CPS-II, cytoplasm, glutamine + CO2 + ATP) + aspartate → carbamoyl aspartate → dihydroorotate → orotate → UMP (UMPS = orotate phosphoribosyltransferase + OMP decarboxylase). UMP→UDP→UTP→CTP (CTP synthetase). dUMP→dTMP (thymidylate synthase, N5,N10-methylene-THF, inhibited by 5-FU). Orotic aciduria: UMPS deficiency - megaloblastic anemia unresponsive to B12/folate, orotic acid in urine; treatment: uridine. Hydroxyurea inhibits ribonucleotide reductase (dNTP synthesis - sickle cell treatment)."),
