Rapid diffusion of water across cell membranes depends on the presence of water channels, called aquaporins. Proximal convoluted tubule have:
|
Aquaporin-1 is localized to both the basolateral and apical membrane of the proximal tubules and its presence allows water to move rapidly out of the tubule along the osmotic gradients set up by active transpo of solutes, and isotonicity is maintained.

ANGLE'S CLASSIFICATION OF MALOCCLUSION
In 1899, Edward Angle classified malocclusion based on the mesial-distal relation of the teeth, dental arches and jaws. He considered the maxillary first permanent molar as a fixed anatomical point in the jaws and the key to occlusion.

Ans. c. Levobunolol Brimonidine, dorzolamide and prostaglandin are topical anti-glaucoma drugs. These drugs do not have systemic side effects, while levobunolol (beta-blocker) is systemic anti-glaucoma drug given orally, having systemic side effects. That is why in patients with glaucoma treated with systemic beta blockers, levobunolol may add on the side effects of beta-blockers, hence avoided in the above mentioned patient.

Not a mechanism of Action of Insulin
|
INSULIN is a protein hormone formed from proinsulin in the beta cells of the pancreatic islets of Langerhans. The major fuel-regulating hormone, it is secreted into the blood in response to a rise in concentration of blood glucose or amino acids. Insulin promotes the storage of glucose and the uptake of amino acids, increases protein and lipid synthesis, and inhibits lipolysis and gluconeogenesis.Tyrosine kinase is any of a group of enzymes that influence signaling between cells, esp. as relates to cell growth and death, cellular adhesion and movement, and cellular differentiation. Abnormalities in tyrosine kinases are found in some human diseases, including chronic myeloid (myelogenous) leukemia.Glucose transpoer type 4, also known as GLUT4, is a protein that in humans is encoded by the GLUT4 gene. GLUT4 is the insulin-regulated glucose transpoer found in adipose tissues and striated muscle (skeletal and cardiac) that is responsible for insulin-regulated glucose transpo into the cell. This protein is expressed primarily in muscle and fat cells, the major tissues in the body that respond to insulin.Na+, K+-ATPase is an enzyme that spans the plasma membrane and hydrolyzes ATP to provide the energy necessary to drive the cellular sodium pump.Hexokinase an enzyme that catalyzes the transfer of a high-energy phosphate group of a donor to d-glucose, producing d-glucose-6-phosphate.Ref: Ganong&;s review of medical physiology;24th edition; page no-436

What is the mechanism of action of Fulvestrant?
|
Fulvestrant: is an estrogen receptor antagonist that downregulates the estrogen receptor and has no agonist effects. Fulvestrant competitively inhibits binding of oestradiol to the estrogen receptor (ER), with a binding affinity that is 89% that of oestradiol. Reduces the number of estrogen receptor. Good to know: It is approved for the treatment of metastatic breast cancer in postmenopausal women who have failed antiestrogen therapy. Given once in a month as a intramusclar injection.

Which of the following are pathological hallmark of Alzheimer&;s disease
|
The two hallmark pathologies required for a diagnosis of Alzheimer&;s disease(AD) are the extracellular plaque deposits of the Beta-amyloid peptide (Ab) and the intracellular flame-shaped neurofibrillary tangles of the Hyper-Phophorylated microtubule binding protein &;tau&;. Histological Hallmarks of Alzheimer&;s disease: b-Amyloid Plaque (Extracellular) Neurofibrillary Tangles (Intracellular) b-Amyloid Neuritic plaques are formed by extracellular accumulation of beta amyloid deposits. &;Neuritic&; or &;Senile&; b-amyloid plaques are an early histopathological sign of Alzheimer&;s disease (that occur rarely in healthy subjects) The amyloid b-protein accumulated in single Neuritic plaques is toxic to surrounding structures and adjacent neurons. Clinico-pathological studies have shown that amyloid burden does not directly correlate with severity or duration of dementia. Neurofibrillary tangles are formed by intracellular accumulation of hyper-phophorylated microtubule binding protein &;tau&; NFT&;s occur in many neurodegenerative diseases and/or a group of diseases called &;taupathies&;. These include Frontotemporal dementia, Pick&;s disease etc., The co-occurence of b-amyloid plaques with NFT&;s suggests a diagnosis of Alzheimer&;s disease (AD) The NFT&;s are toxic to the neurons and neurons with NFT&;s eventually die and degnerate leaving a residual &;ghost tangle&; in the extramedullary space reminding of the pyramidal cell body in which it was initially formed. Clinico-pathological studies have shown that dementia correlates more strongly with NFT&;s than with senile plaques (b-Amyloid) Ref: Bailey and Love 27th edition

It transfers two-carbon unit (with keto group) from xylulose-5-phosphate to ribose-5-phosphate to form a 7 carbon sugar, sedoheptulose-7-phosphate and glyceraldehyde-3- phosphate. Transketolase enzyme will transfer the group from a donor ketose to an aldose acceptor. In thiamine deficiency transketolase activity is decreased. The reaction may be summarized as 5C + 5C = 7C + 3C. REF: DM VASUDEVAN TEXTBOOK OF BIOCHEMISTRY, SIXTH EDITION,PG.NO.,114.

Streptococcus mutans is an alpha Hemolytic streptococcus which is a pa of the normal flora of the oral cavity. This gram-positive coccus is commonly found in the mouth from where it can spread to cause dental caries or endocarditis in individuals with risk factors(dental extraction in individuals with damaged hea valves). The bacteria has a polysaccharide coat that allows it to stick to teeth and also to the damaged hea valves. It produces acid from sugar in saliva and this promotes erosion of tooth enamel.

Biconcave shape of RBC is useful for all, EXCEPT:
|
Biconcave shape allows easy folding of RBC on itself when it passes through capillaries. It allows considerable alteration in cell volume. Thus can withstand considerable changes of osmotic pressure and resisit hemolysis. Also Know: In humans, they survive in the circulation for an average of 120 days. The average normal red blood cell count is 5.4 million/L in men and 4.8 million/L in women. The number of red cells is also conveniently expressed as the hematocrit, or the percentage of the blood, by volume, that is occupied by erythrocytes. Each human red blood cell is about 7.5 m in diameter and 2 m thick, and each contains approximately 29 pg of hemoglobin. There are thus about 3 x 10 13 red blood cells and about 900 g of hemoglobin in the circulating blood of an adult man. Ref: Barrett K.E., Barman S.M., Boitano S., Brooks H.L. (2012). Chapter 31.

The person gets tired early d/t high temp. 2. Heat cramps - these are painful spasms of voluntary muscles following strenous work in hot conditions, These cramps are caused by loss of water and salt from profuse sweating. 3. Heat syncope (heat exhaustion, heat collapse) - It is a condition of collapse without increase in body temperature, following exposure to hot and humid atmosphere. - On examination,. face is pale, .skin cold, the temperature subnormal - The pt. usually recovers when placed at rest. Death is unusual and may occur d/t hea failure. 4. Heat stroke - (heat hyperpyrexia, sub stroke) - It is due to impairment of body's heat regulating mechanism caused by failure of cutaneous circulation & sweating, following prolonged exposure to hot, humid conditions. - The onset is usually sudden with sudden collapse and loss of consciousness. Predominant symptoms may also be seen (i.e. headache, nausea, vomitting, dizziness, mental confusion, muscle cramps, excessive thirst, excessive desire to micturate) - The skin is dry, hot and flushed with complete absence of sweating - Body temperature rises as high as 43degC (hence k/a hyperpyrexia) when body temp. rises above 42degC vasodilation occurs with decrease in blood volume leading to circulatory collapse and cardiac failure. - Delirium and convulsions may precede death. - Moality rate in this condition is relatively high. - Fatal period varies from few minutes to 3 days.

Which is the common amino acid between urea cycle and TCA?
|
Ans. (a) AsparateRef: Satyanarayan Biochemistry, pg. 339Role of Aspartate in urea cycle:* Aspartate participates in urea cycle for condensation with citrulline to form Argino succinic acid. The reaction is catalyzed by Argino succinic acid synthetase (Asparate provides one out of the two nitrogens of urea, the other nitrogen is contributed by Glutamate).* In the subsequent reaction, Argino succinic acid undergoes a lytic reaction to form Arginine and fumarate. Fumarate forms a link between TCA cycle and urea. Fumarate can be recycled to form oxaloacetate, through intermediate formation of malate that can be transmmated to form aspartate, to get reutilized in the urea cycleLink between TCA and urea cycleRole of Aspartate in TCA cycle* Oxaloacetate, the keto acid obtained from Aspartate by transamination is an intermediate of TCA cycle.* Oxaloacetate can either be utilized in TCA cycle or be channeled to the pathway of gluconeogenesis.* Hence asparatate is a common intermediate of TCA cycle (through oxaloacetate) and urea cycle (directly)

A 45-year-old woman has experienced worsening arthritis of her hands and feet for the past 15 years. On physical examination, there are marked deformities of the hands and feet, with ulnar deviation of the hands and swan-neck deformities of the fingers. Laboratory studies show an elevated level of rheumatoid factor. CBC shows hemoglobin, 11.6 g/dL; hematocrit, 34.8%; MCV, 87 mm3; platelet count, 268,000/ mm3; and WBC count, 6800/ mm3. There is a normal serum haptoglobin level, serum iron concentration of 20 mg/ dL, total iron-binding capacity of 195 mg/dL, percent saturation of 10.2, and serum ferritin concentration of 317 ng/mL. No fibrin split products are detected. The reticulocyte concentration is 1.1%. What is the most likely mechanism underlying this patient's hematologic abnormalities?
|
The iron concentration and iron-binding capacity are low; however, in contrast to the finding in anemia of iron deficiency, the serum ferritin level is increased. This increase is typical of anemia of chronic disease. In this case, the chronic disease is rheumatoid arthritis. Underlying chronic inflammatory or neoplastic diseases increases the secretion of cytokines such as interleukin-1, tumor necrosis factor, and interferon-g. These cytokines promote the sequestration of iron in storage compartments and depress erythropoietin production. Autoantibody hemolytic anemias occur in several autoimmune diseases, such as systemic lupus erythematosus, but not usually in patients with rheumatoid arthritis, as in this case. Normal serum haptoglobin rules out intravascular hemolysis; iron is recycled at a rapid rate. Impaired synthesis of b-globin chains gives rise to b-thalassemia, also characterized by hemolysis. Complement lysis is enhanced in paroxysmal nocturnal hemoglobinuria, which results from mutations in the PIGA gene. Patients with this disorder have a history of infections. Sequestration of RBCs in the spleen occur when RBC membranes are abnormal, as in hereditary spherocytosis or sickle cell anemia, or RBCs are coated by antibodies, as in autoimmune hemolytic anemias. Metastases are space-occupying lesions (myelophthisic process) that can lead to leukoerythroblastosis, with nucleated RBCs and immature WBCs appearing on the peripheral blood smear.

True about femoral hernia is -
|
Answer is 'b' i.e. Pregnancy is common cause Femoral hernia In this hernia the abdominal contents pass through the femoral ring, traverse the femoral canal and come out through the saphenous opening. It is more common in females (But remember that most common hernia in the females is not femoral, but it is indirect inguinal) Femoral hernia is rare in men and nulliparous women but more common in multiparous women due to stretching of the pelvic ligaments. In contrast to inguinal hernia, femoral hernia is rare in infancy and childhood. It is rare before pubey. It is more common on right side It is bilateral in 20% of cases. Among all the types of hernia, femoral hernia is most liable to become strangulated, mainly because of the narrowness of the neck of the sac and the rigidity of the femoral ring. Infact strangulation is the initial presentation of 40% of femoral hernias. About option 'd' Cryptorchidism is associated with indirect inguinal hernias due to patent processus vaginalis.

A 74-year-old woman has noted increasing size and number of darker brown patches on the dorsum of each hand for the past 15 years. They do not change with sun exposure, are nonpruritic, and non-tender. On examination, these 0.5- to 1-cm lightly pigmented lesions are flat. Which of the following is the most likely microscopic finding in these lesions?
|
Unlike a freckle that darkens upon light exposure, lentigo (pleural:lentigenes) does not. There is a focal increase in melanocytes of the basal layer, along with thinning of epidermis and elongation of rete ridges. Lentigines can occur at any age; those in older persons may be termed senile lentigines or age spots. A nevus typically forms a nodule and likely appears much earlier in life. Loss of melanin is termed vitiligo and is a separate process from melanocyte hyperplasia. A collection of mast cells can produce urticaria pigmentosa, which often has a light brown appearance, but pruritus is common. Some superficial fungal infections (black piedra) may be pigmented, but they typically do not persist for years.

Transmission of R factor is by -
|
Conjugation
Bacterial conjugation is the transfer of genetic material between bacteria through direct cell to cell contact or through a bridge- like the connection between two cells.
Conjugation is a process whereby a donor (male) bacterium makes physical contact with a recipient (female) bacterium.
Donor status is determined by the presence of plasmid.
This plasmid codes for specialized fimbria (sex pilus) and for self-transfer.
Sex pilus (conjugation tube) helps in the transfer of genetic material from male bacterium to female bacterium.
The plasmid is known as transfer factor (sex factor or fertility factor).
The plasmid may be R factor, which codes for transferrable multiple drug resistance.
The DNA of the plasmid replicates during transfer so that each bacterium receives a copy → Recipient becomes a donor and the donor retains its donor status.

Investigation of choice in postcoital bleeding in a 60 years old lady is :
|
Ans. is b i.e. Colposcopy and biopsy investigation of choice in post-coital bleeding in a 60 years old lady (which suggests carcinoma cervix) is Colposcopy and Biopsy. The aim of Colposcopy is : - to confirm the diagnosis - to identify the extent of lesion - it allows conservative treatment in case of precancerous lesions. Pap smear is not the investigation of choice, as it is a screening procedure. If pap smear is negative in this case (In postmenopausal females, where there are less metaplastic changes at squamo columnar junction) we still have to confirm by Colposcopy. Cone biopsy is a destructive method and is advised only if diagnosis cannot be confirmed by colposcopy or SCJ is not visualised.

Primary pleural tumor is ?
|
Ans. is 'a' i.e., Mesothelioma & 'd' i.e., Fibroma The pleura may be involved by primary or secondary tumors. Primary tumors Benign - Solitary fibrous tumor (benign fibrous mesothelioma or benign mesothelioma or pleural fibroma). Malignant - Malignant mesothelioma. Secondary tumors More common than primary tumors. Most common primary sites are lung and breast. Pleural fibroma (Benign fibrous mesothelioma) This is the primary benign lesion of pleura. The tumor is often attached to the pleural surface by a pedicle. These tumor do not usually produce a pleural effusion and have no relationship to asbestos exposure (in contrast to malignant mesothelioma). They consist of dense fibrous tissue with occasional cysts filled with viscid fluid. Microscopically, the tumors show whorls of reticulin and collegen fibers among which are interspersed spindle cells resembling fibroblasts. The tumor cells are CD 34 (+)ve and keratin negative by immunostaining. This feature can be diagnostically useful in distinguishing these lesions from malignant mesothelomas which is CD34 (-)ve and keratin positive.

Epalrestat is a
|
Epalrestat is analdose reductase inhibitor. There by it reduces the formation of sorbitol from glucose. Sorbitol acts like a tissue toxin. "Long-term treatment with epalrestat is well tolerated and can effectively delay the progression of diabetic neuropathy and ameliorate the associated symptoms of the disease, paicularly in subjects with good glycemic control and limited microangiopathy." Epalrestat is a drug that we use in diabetic but it is not a antidiabetic drug (i.e. it does not reduce the blood sugar level).

The MOST appropriate time for self-examination of breast in relation to menstraution in a pre-menopausal woman is?
|
Breast self-examination is to be performed by all women above 18 years throughout their life. It should be performed every month at the same time of menstrual cycle. For pre-menopausal women: The best time is right after the menstrual cycle ends (7-10 day; after menstrual cycle stas) as at this time the breasts are less swollen and less tender a; estrogen levels are low. For post-menopausal women: BSE at any specific date can be selected for each month For women on H: BSE to be done after finishing each cycle of H For women on OCP: BSE should be performed with the sta of new pill pack each month

Ratio of sulfamethoxazole and trimethoprim in cotrimoxazole tablet is:-
|
COTRIMOXAZOLE This is a fixed dose combination of sulfamethoxazole and trimethoprim in a ratio of 5:1. Due to different bioavailability (more for sulfamethoxazole), plasma concentration of the two drugs attained is 20:1 (in vivo), which is the best bactericidal concentration required. The bactericidal activity is due to sequential blockade at two steps in the DNA synthesis (sulfamethoxazole inhibits folate synthase and trimethoprim inhibits DHFRase). It is the drug of choice for pneumocystosis, nocardiosis and infections caused by Burkholderia cepacia.

Type B gastritis is
|
Type B gastritis mainly involves the region of antral mucosa (hence antral predominant not body predominant.) and is more common. It is also called hypersecretory gastritis due to excessive secretion of acid, commonly due to infection with H. pylori. These patients may have associated peptic ulcer. Unlike Type A gastritis, this form of gastritis has no autoimmune basis nor has an association with other autoimmune diseases. Type A is body predominant. Type AB gastritis effects the mucosal region of A as well as B types. This is the most common gastritis in all age groups. It is also called environmental gastritis, mixed gastritis, chronic atrophic gastritis. TEXTBOOK OF PATHOLOGY HARSH MOHAN 6TH EDITION PAGE NO:547

An ABG analysis shows : pH 7.2, raised pCO2, decreased HCO3; diagnosis is :
|
Answer is C (Respiratory and metabolic acidosis) The acid base disorder is therefore both respiratory and metabolic acidosis. There is acidosis (pH < 7.35). Raised PCO2 (acidosis) indicates that change in CO2 is in keeping with change in pH. The respiratory component is therefore primary. Decreased HCO3 (acidosis) indicates that change in HCO3 is also primary. The acid base disorder is therefore both respiratory and metabolic acidosis.
