Ref
Temozolomide is an oral alkylating agent used for the treatment of Grade IV
astrocytoma — an aggressive brain tumor, also known as glioblastoma multiforme — as well
as for treating melanoma, a form of skin cancer. Temozolomide is also indicated for relapsed
Grade III Anaplastic Astrocytoma and not indicated for, but as of 2011 used to treat
oligodendroglioma brain tumors in some countries, replacing the older (and less welltolerated) PCV (Procarbazine-Lomustine-Vincristine) regimen.
The agent was developed by Malcolm Stevens and his team at Aston University in
Birmingham, A derivative of imidazotetrazine, temozolomide is the prodrug of MTIC (3methyl-(triazen-1-yl)imidazole-4-carboxamide). It has been available in the US since August
1999, and in other countries since the early 2000s.
The therapeutic benefit of temozolomide depends on its ability to alkylate/methylate DNA,
which most often occurs at the N-7 or O-6 positions of guanine residues. This methylation
damages the DNA and triggers the death of tumor cells. However, some tumor cells are able
to repair this type of DNA damage, and therefore diminish the therapeutic efficacy of
temozolomide, by expressing an enzyme called O-6-methylguanine-DNA methyltransferase
(MGMT) or O-6-alkylguanine-DNA alkyltransferase (AGT or AGAT). In some tumors, epigenetic
silencing of the MGMT/AGT gene prevents the synthesis of this enzyme, and as a consequence
such tumors are more sensitive to killing by temozolomide. Conversely, the presence of MGMT
protein in brain tumors predicts poor response to temozolomide and these patients receive
little benefit from chemotherapy with temozolomide

ref --- Kegel exercise
A pelvic floor exercise, more commonly called a Kegel exercise (named after Dr. Arnold
Kegel), consists of contracting and relaxing the muscles that form part of the pelvic floor,
which are now sometimes colloquially referred to as the "Kegel muscles". Several tools exist to
help with these exercises, though many are ineffective. Exercises are usually done to reduce
urinary incontinence and aid with childbirth in women, and reduce premature ejaculatory
occurrences in men,as well as increase the size and intensity of erections.
The aim of Kegel exercises is to improve muscle tone by strengthening the pubococcygeus
muscles of the pelvic floor. Kegel is a popular prescribed exercise for pregnant women to
prepare the pelvic floor for physiological stresses of the later stages of pregnancy and vaginal
childbirth. Kegel exercises are said to be good for treating vaginal prolapse and preventing
uterine prolapse in women and for treating prostate pain and swelling resulting from benign
prostatic hyperplasia (BPH) and prostatitis in men. Kegel exercises may be beneficial in
treating urinary incontinence in both men and women.Kegel exercises may also increase
sexual gratification and aid in reducing premature ejaculation.Many actions that are controlled
by Kegel muscles include "holding in" urine or avoiding defecation. Reproducing these types of
muscle actions can yield stronger Kegel muscles.
A Kegel exerciser
Pelvic toning devices
A pelvic toning device (generically referred to as a Kegel exerciser, pelvic floor toner, pelvic
floor muscle toner or pelvic toner) is a medical or pseudo-medical device designed to help
women exercise their pelvic floor muscle and improve the muscle tone of the pubococcygeal or
vaginal muscle.
The original pelvic toning device was the perineometer invented by Arnold Kegel to facilitate
the measurement of the strength of the pubococcygeus muscle when it was resting and being
actively squeezed - sometimes referred to as the Kegel tone.
Unfortunately his device was a combination of rubber balloons and tubes that measured
pressure using a column of water. It was neither easy to use nor portable.
During the latter part of the 20th century a number of medical and pseudo-medical devices
were developed and launched onto the market. Some of these are used in a clinical setting,
but most are designed for women to use in the privacy of their own home.
Pelvic toning devices fall into a number of different types:
barbells, vaginal weights or cones designed to be held in the vagina. The action of
passively/actively retaining the device internally is supposed to improve muscle tone. Barbells
are made of smooth, polished solid stainless steel, cylindrical in shape, with a rounded bulge
at each end. They typically weigh one pound (454 g) and measure approximately 6¾ inches
(17.1 cm) in length with a diameter of one inch (2.5 cm) at the widest part. Being made of
stainless steel, vaginal barbells are nonporous and can be wiped clean with a cloth moistened
with mild soap and water.
electro-stimulation or TENS devices that administer an electrical current through an internal
probe. The current stimulates the adjacent muscles to twitch.
rubber resistance balls and indicators. These devices provide a nominal resistance to squeeze
against. An advantage of rubber bulb devices is that they provide visual feedback (via a
gauge) of how much pressure is being applied.
progressive resistance vaginal exercisers with springs are the only devices that meet all of
Kegel's criteria. They provide a biofeedback that the correct muscles are being engaged and
are capable of fulfilling the basic fundamentals of an exercise regime by applying a variable
and increasing resistive force to maximise the exercise effort.
Unfortunately there are a number of products on the market that have no impact at all on the
pubococcygeus muscle. If the PC muscle is not engaged then it is impossible to improve the
muscle tone or strengthen the muscle. Devices that are used externally, for example between
the thighs, may exercise the adductor muscle but do nothing for the pelvic floor.
Benefits for women
Factors such as pregnancy, childbirth, aging, being overweight, and abdominal surgery such
as cesarean section, often result in the weakening of the pelvic muscles. This can be assessed
by either digital examination of vaginal pressure or using a Kegel perineometer. Kegel
exercises are useful in regaining pelvic floor muscle strength in such cases.
Urinary incontinence
The consequences of weakened pelvic floor muscles may include urinary or bowel
incontinence, which may be helped by therapeutic strengthening of these muscles. A metaanalysis of randomized controlled trials by the Cochrane Collaboration concluded that "PFMT
[Pelvic floor muscle training] be included in first-line conservative management programs for
women with stress, urge, or mixed, urinary incontinence...The treatment effect might be
greater in middle aged women (in their 40s and 50s) with stress urinary incontinence
alone...".
Pelvic prolapse
The exercises are also often used to help prevent prolapse of pelvic organs. A meta-analysis of
randomized controlled trials by the Cochrane Collaboration concluded that "there is some
encouragement from a feasibility study that pelvic floor muscle training, delivered by a
physiotherapist to symptomatic women in an outpatient setting, may reduce severity of
prolapse".
Benefits for men

Though most commonly used by women, men can also use Kegel exercises. Kegel exercises
are employed to strengthen the pubococcygeal muscle and other muscles of the pelvic
diaphragm. Kegels can help men achieve stronger erections and gain greater control over
ejaculation.[5] The objective of this may be similar to that of the exercise in women with
weakened pelvic floor: to increase bladder and bowel control and sexual function'
Incontinence
Regarding postprostatectomy urinary incontinence, a meta-analysis of randomized controlled
trials by the Cochrane Collaboration found "conflicting information about the benefit of pelvic
floor muscle training for either prevention or treatment of urine leakage".
Sexual function
Kegel workouts can provide men with stronger erections.Research published in 2005 issue of
BJU International, have shown that pelvic floor exercises could help restore erectile function in
men with erectile dysfunction. There are said to be significant benefits for the problem of
premature ejaculation from having more muscular control of the pelvis. It is also possible that
strengthening the pelvic floor may allow some men to achieve a form of orgasm without
allowing ejaculation, and thereby perhaps reach more than one "climax" during sexual
activity.In men, this exercise lifts up the testicles, also strengthening the cremaster muscle, as
well as the anal sphincter muscles, as the anus is the main area contracted when a Kegel is
done. This is because the pubococcygeus muscle begins around the anus and runs up to the
urinary sphincter.

104) The function of a gene is determined by
a.southern blot
b.western blot
c.inserting in trangenic mice
d. inserting as a knock out gene ANS
Knockout : Remove complete or part of the gene from the genome
Knockin : inserting external elements in to the genome like GFP/RFP or LacZ
Transgenic : over expressing particular gene in in vivo, similar way like overexpressing
proteins in mammalian cells
When researchers isolate human genes with unknown functions, they can create knockout
mice with these genes and observe the results. Instead of creating merely the mouse
equivalent of the human gene, researchers are able to reproduce and express actual human
genes and their corresponding proteins in mice. Subsequent offspring will inherit not only the
instructions coded by their original mouse genome, but also the traits coded for by the
inserted human DNA. This helps researchers understand health and disease by observing how
genes work in cells.
Knockout mice have many benefits. They not only allow researchers to determine gene
function and understand diseases at the molecular level, but they also aid scientists in testing
new drugs and devising novel therapies.
http://www.ornl.gov/sci/techresources/Human_Genome/faq/compgen.shtml
Transgenic Mice
One of the simplest ways to study gene function in a mouse is exogenous expression of a
protein in some or all tissues. For this type of genetic modification, a new piece of DNA is
introduced into the mouse genome. This piece of DNA includes the structural gene of interest,
a strong mouse gene promoter and enhancer to allow the gene to be expressed and vector
DNA to enable the transgene to be inserted into the mouse genome
Currently, the phrase "transgenic mouse" generally refers to any mouse whose genome
contains an inserted piece of DNA, originating from the mouse genome or from the genome of
another species, and the term includes the standard transgenic mouse as well as a knockin or
knockout mouse http://www.cellmigration.org
According to my opinion Inserting as knock out gene is the best option

Immune complex formation structure of protein involved is
105) In
a) Primary
b) Secondary
c) Tertiary ANS
d) Quaternary
Tertiary structure ,the immunoglobulin fold is the domain involved which is a tertiary
structure.Even though Ig Has more than one polypeptide chain .For its functional fulfillment
domain is needed which is a tertiary structure.
COVALENTLY-CONNECTED TERTIARY DOMAINS
In this class of protein, domains are usually formed as modules covalently "strung together"
on a single polypeptide chain. The individual chains of antibodies are like this, strings of
immuno-globulin domains. However, light and heavy chains then combine to produce heteromultimers, which may even associate into higher complexes, as with IgM

Best option is Tertiary structure
106) Which of the following amino acid can have o-glycoxylation linkage in oligosachride molecule
A.Asparagine
B. glutamine
C. serine
D. cysteine
Ans Serine
THERE ARE THREE MAJOR CLASSES OF GLYCOPROTEINS
Based on the nature of the linkage between their polypeptide chains and their oligosaccharide
chains, glycoproteins
can be divided into three major classes (Figure 47–1): (1) those containing an O-glycosidic
linkage (ie, Olinked),
involving the hydroxyl side chain of serine or threonine and a sugar such as N acetylgalactosamine
(GalNAc-Ser[Thr]); (2) those containing an N-glycosidic linkage (ie, N-linked), involving the
amide nitrogen of
asparagine and N -acetylglucosamine (GlcNAc-Asn); and (3) those linked to the carboxyl
terminal amino acid of a
protein via a phosphoryl-ethanolamine moiety joined to an oligosaccharide (glycan), which in
turn is linked via

D. Negative supercoiling
Answer isRestriction enzymes Cut at Palindromic Sequences
Structure and function of type II restriction endonucleases
ABSTRACT
More than 3000 type II restriction endonucleases have been discovered. They recognize short,
usually palindromic, sequences of 4–8 bp and, in the presence of Mg2+, cleave the DNA within
or in close proximity to the recognition sequence. The orthodox type II enzymes are
homodimers which recognize palindromic
sites.[http://nar.oxfordjournals.org/content/29/18/3705.full]
108) Which of the following proteins cannot be phosphorylated using protein kinase in prokaryotic
organisms
A.Aspargine
B.Cysteine
C.Serine
D.Methionine ANS
Reference
Phosphorylation is found most commonly on specific serine and threonine amino acid residues
in proteins, but it also occurs on tyrosine and other amino acid residues (histidine, aspartic
acid, glutamic acid) as well. In most cells, about 90% of the protein phosphorylation appears
on serine, 10% on threonine and ~0.05% on tyrosine residues. Therefore, protein-tyrosine
phosphorylation levels appear to be about 2000-times lower than protein-serine
phosphorylation levels and 200-times lower than protein-threonine phosphorylation levels. In
cells like activated platelets, tyrosine phosphorylation can be orders of magnitude higher
109) Keratin is present in both skin and nail .But skin is more flexible than nail. Reason ?
a. increased no of disulphide bonds ANS
b. decreased no of water molecules
c. increased Na content
d. increased hydrogen bonds
More the Disulphide bond More tensile the protein,Hence harder.So answer is Increased
Disulphide bond.
Reference
PROTEIN STRUCTURE
Nails are made of a protein called keratin, which is also found in skin and hair. The difference
is the sulfur content. Keratin contains an amino acid called cysteine. Cysteine contains the
sulfur atom. Two cysteines combine to form a disulfide bond. The number of these disulfide
bonds in the keratin is what makes the difference between skin, hair and nails. Lots of
disulfide bonds means very little flexiblity, like a nail. Fewer disulfide bonds results in more
flexibility, like hair and skin.

Abstract
Determination of thyrotropin (TSH) by sensitive immunometric assays is currently judged as
the most sensitive and also most cost-effective first-line approach to thyroid function testing.
Further improvement of assay sensitivity has led to the description of third generation TSH
assays with a functional sensitivity in the range of 0.01 to 0.02 mU/l
Third generation TSH assays have become available with detection limits of about 0.01 mU/L.
Because of the considerably lower detection limit, these assays can reliably distinguish
between normal and hyperthyroid patients(Boulder Medical Center Journal)
These are the refernces I could collect.Please contribute more details
Extremely sensitive (fourth-generation) assays can detect TSH levels 0.004 mU/L, but, for
practical purposes, assays sensitive to 0.1 mU/L are sufficient[Harrison 18th editione book

Reference-Biochemical Case Histories [new chapter added in Harper 28th edition]
A 1-year-old girl, an only child of Caucasian background, was brought to the clinic at the
Hospital for Sick Childrenby her mother. She had been feverish for the past 24 h and was
coughing frequently. The mother stated that herdaughter had experienced three attacks of
"bronchitis" since birth, each of which had been treated with antibioticsby their family
physician. The mother had also noted that her daughter had been passing somewhat bulky,
foulsmellingstools for the past several months and was not gaining weight as expected. In
view of the history ofpulmonary and gastrointestinal problems, the attending physician
suspected that the patient might have CF,
although no family history of this condition was elicited.
Laboratory Findings
Chest x-rays showed signs consistent with bronchopneumonia. Culture of sputum revealed
predominantlyPseudomonas aeruginosa. Fecal fat was increased. A quantitative pilocarpine
iontopheresis sweat test wasperformed, and the sweat Cl– was 70 mmol/L (>60 mmol/L is
abnormal); the test was repeated a week later withsimilar results.
Treatment
The child was given an appropriate antibiotic and referred to the cystic fibrosis clinic for
further care. Acomprehensive program was instituted to look after all aspects of her health,
including psychosocialconsiderations. She was started on a pancreatic enzyme preparation
(given with each meal) and placed on ahigh-calorie diet supplemented with multivitamins and
vitamin E. Postural drainage was begun for the thickpulmonary secretions. Subsequent
infections were treated promptly with appropriate antibiotics and with anaerosolized
recombinant preparation of human DNase that digests the DNA of microorganisms present in
therespiratory tract. At age 6 years, she had grown normally, had been relatively free of
infection for a year, wasattending school and making satisfactory progress. Serious chronic
cases of CF in which the lungs are severelycompromised are candidates for lung transplants,
although the effiacy of this treatment has been challengedrecently.
Research on gene therapy for CF is under examination (eg, using recombinant viruses
encoding the CFTRprotein). Another line of research is investigating whether small molecules
can be found for clinical use that helpabnormally folded CFTR molecules re-fold into at least
partially active molecules.
Discussion
CF is a prevalent and usually serious genetic disease among whites in North America. It affects
approximately1:2500 individuals and is inherited as an autosomal recessive disease; about
one person in 25 is a carrier. It is adisease of the exocrine glands, with the respiratory and
gastrointestinal tracts being most affected. Adiagnostic hallmark is the presence of high
amounts of NaCl in sweat, reflecting an underlying abnormality inexocrine gland function (see
below). Pilocarpine iontophoresis has generally been used to allow collection ofsufficient
amounts of sweat for analysis. Iontophoresis is a process by which drugs are introduced into
the body (inthis case the skin) via use of an electrical current. Its use is diminishing as the
availability of specific genetic probes
increases.
The classic presentation of CF is that of a young child with a history of recurrent pulmonary
infection and signs ofexocrine insufficiency (eg, fatty, bulky stools due to a lack of pancreatic
lipase), as in the present case. However,the disease is clinically heterogeneous, which at least
partly reflects heterogeneity at the molecular level Approximately 15% of patients may have
sufficient pancreatic function to be classified as "pancreaticsufficient."
For reasons related to abnormalities in Cl– and Na+ transport the pancreatic ducts and the
ducts ofcertain other exocrine glands become filled with viscous mucus, which leads to their
obstruction. This mucus inalso present in the bronchioles, leading to their obstruction; this
favors the growth of certain bacteria (eg,Staphylocococu aureus and P aeruginosa ) that cause
recurrent bronchopulmonary infections, eventuallyseriously compromising lung function. In
turn, the pulmonary disease can lead to right ventricular hypertrophy andpossible heart
failure. Patients usually die of pulmonary infection or heart failure. In recent years,
morepatients have been living into their 30s and later, as the condition is now diagnosed
earlier and appropriatecomprehensive therapy started. Sometimes, problems due to lack of
pancreatic secretions can be present at birth,
the infants presenting with intestinal obstruction due to very thick meconium (meconium
ileus). Other patientsless severely affected, may not be diagnosed until they are in their teens
or later. CF also affects the genital tractand most males and many females are infertile
121) All except occurs on Decrease in liver glucose level :
a.inhibition of PFK2
b.Activation of Fructose 2,6bisphosphatase
c.increase in glucagon
d.increase in Fructose2,6bis phosphate ANS
When there is an abundant supply of glucose, the concentration of fructose 2,6-bisphosphate
increases, stimulating glycolysis by activating phosphofructokinase-1 and inhibiting fructose
1,6-bisphosphatase. In the fasting state, glucagon stimulates the production of cAMP,
activating cAMP-dependent protein kinase, which in turn inactivates phosphofructokinase-2
and activates fructose 2,6-bisphosphatase by phosphorylation. Hence, gluconeogenesis is
stimulated by a decrease in the concentration of fructose 2,6-bisphosphate, which inactivates
phosphofructokinase-1 and relieves the inhibition of fructose 1,6-bisphosphatase.[Harper 28th
edition]
Answer is increase in Fructose2,6bis phosphat e

Q. Common enzyme in cholestrol and ketone metabolism
a. HMG coA reductase
b HMG coA lyase
c HMG coA synthase
d. Thiolase
answer -HMG CoA Synthase
Cholesterol Synthesis
Ketogenesis
Acetoacetyl-CoA, which is the starting material for ketogenesis, also arises directly from the
terminal fourcarbons of a fatty acid -oxidation(Figure 22–7). Condensation of acetoacetyl-CoA
with another molecule of
acetyl-CoA by 3-hydroxy-3-methylglutaryl-CoA synthase forms 3-hydroxy-3-methylglutarylCoA (HMG-CoA)[Harper28th Chapter 22]Diagram 22-7
Expl-Acetoacetyl Co A is the starting material for ketogenesis..Acetyl CoA released by
Oxidation is added to the AcetoAcetyl Co A To Form HMG CoA.So Thiolasecannot be
considered a part of Ketogenesis according to Harper.
But many books says Acetyl CoA is the staarting material.But Harper doesnt.
