Down regulation: There is internal distribution of receptors such that few receptors are available on the cell surface. Removal of receptor to the interior or cycling of membrane components alters the responsiveness to the hormone. In another type of down regulation, H-R complex, after reaching nucleus controls the synthesis of receptor molecule. Some times Covalent modification of receptors by phosphorylation decreases binding to hormone, which diminishes signal transduction. Up regulation: Some hormones like prolactin up regulate,(increase) their own receptors which ultimately increases the biological response and sensitivity in target tissues. Receptors and diseases: Abnormality in the receptors cause the following diseases. This molecule mediates phosphorylation of intracellular proteins, by activating protein kinase A. Protein kinase A is a tetramer having two regulatory units and two catalytic units (R2C2). The inhibitory system consists of different receptors (Ri), and inhibition regulatory complex (Gi). Bacterial Toxins: Vibrio cholerae produce entero toxin which binds to ganglioside (Gm) from the intestinal mucosa. Intracellular Ca is increased by a) Entry of Ca from extra cellular region when stimulated. Maniac depression: Patients who suffer from maniac depression are treated with Lithium. The disease is a result of high levels of hormone/ neurotransmitters, whose actions stimulate phosphatidyl inositol cycle. Chemistry: It is composed of 2 polypeptide chains, A and B, containing total of 51 amino acids. Structure of Insulin C peptide=31-65, A chain=66-86, B chain=1-30 Porcine Insulin is similar to human insulin except Threonine is substituted by Alanine at 30 position of B chain. Biosynthesis of Insulin Pre-pro insulin (109 amino acids) is synthesized in the endoplasmic reticulum of B Cells of islet of Langerhans. Insulinase or Glutathione-insulin trans hydrogenase is located in liver, kidney, muscles and placenta. Mechanism of insulin action When insulin binds to specific receptor, several events take place. One or more signals are generated; however the role of second messenger is uncertain. Regulation of Insulin Receptors High levels of insulin in blood decrease the insulin receptors on the target membrane. Here insulin-receptor complex is internalized, there by causing less sensitivity of target tissue. Regulation of Insulin secretion: Secretion of insulin is closely coordinated with the release by pancreatic - cells. Gastrointestinal hormones like secretin and others are released in response to intake of food. They induce anticipatory secretion of insulin, before the rise of glucose in the portal vein. Therefore when glucose is given orally it induces more insulin secretion than when given intravenously. Synthesis, release of insulin is decreased when there is scarcity of dietary fuels. Metabolic Role of Insulin Carbohydrate metabolism: Insulin produces lowering of blood glucose and increases glycogen stores. It is due to increased translocation of glucose transporters from Golgi to plasma membrane. Paradoxycal action of insulin * Insulin stimulates protein phosphatase-1 which dephosphorylates and activates key enzyme glycogen synthase.

Severity of motor impairment Distinguish and individually quantify spasticity, strength, presence of fixed contractures, and coordination. Known aetiologies and risk factors Nature and timing: prenatal, perinatal, or postnatal/neonatal. Known neuroimaging findings · Periventricular leukomalacia, cerebral malformations, etc. Prenatal factors · Prenatal factors account for >60% of term-born children and for >15% of pre-term. Evidence against intrapartum hypoxia as the main cause · History of only mild neonatal encephalopathy (Sarnat grade I). Neuroimaging findings for atypical for injury at term: schizencephaly; other neuronal migration disorders; periventricular leukomalacia (see b p. Progression of motor signs (Note: ataxia and dyskinesia are usually preceded by a period of hypotonia in infancy). Lower-limb spastic weakness (diplegia) · Spinal cord lesion (ask about continence, check sensation). Results will focus further investigations; recommended for all children, particularly term-born. Risk factors include: mechanical ventilation; hypotension, hypoxaemia, acidosis, hypocarbia, patent ductus arteriosus. Consider: leukodystrophies if there is an atypical distribution of white matter changes; or if marked cerebral or cerebellar atrophy/hypoplasia are present. A thin juxtaventricular rim of normal myelination should be visible posteriorly-if not, suggests a leukodystrophy. Consider Biotinidase deficiency, 3-phosphoglycerate dehydrogenase deficiency, Pelizaeus­Merzbacher, congenital disorders of glycosylation, Menkes, Sjoegren­Larsson, other metabolic leukodystrophies. Basal ganglia and thalamic lesions Bilateral infarctions in the putamen (posterior) and thalamus (ventrolateral nuclei) can result from perinatal acute, severe hypoxic­ischaemic injury at term. Kernicterus is now more common in pre-term infants-look for globus pallidus lesions. Involvement of the globus pallidus or caudate is suspicious for metabolic disease (especially mitochondrial disease and organic acidurias). Porencephaly this is a focal peri-ventricular cyst or irregular lateral ventricle enlargement, often a remnant of foetal/neonatal periventricular haemorrhagic venous infarction. Insult is typically second trimester, but extensive unilateral lesions are possible after arterial ischaemic or haemorrhagic stroke at term. Cortical infarctions Symmetrical parasagittal and parieto-occipital/fronto-parietal watershed lesions can result in spastic quadriparesis. Focal symmetrical infarctions in perisylvian areas can lead to the Worster­Drought phenotype. Unilateral lesions suggest a thrombo-embolic cause; they result in spastic hemiplegia (usually upper limb-predominant). Cystic encephalomalacia Multiple subcortical cysts and gliosis occur (iT2 signal in remaining white matter); there is septation in the cysts. If diffuse consider neonatal/infantile meningitis; if there are watershed areas, consider severe perinatal ischaemic injury. Schizencephaly this is a neuronal migration disorder; specific genes are implicated. Disorders of neuronal proliferation, migration and organization including heterotopias, lissencephalies and hemimegalencephaly. Many specific genetic disorders: can also be caused by early to mid-gestational teratogens. Agenesis of corpus callosum suggests an early gestation insult, typically genetic cerebral dysgenesis. Cerebellar hypoplasia and atrophy A non-progressive lesion (hypoplasia) may be indistinguishable from a progressive lesion (atrophy)-check antenatal ultrasound for clues. Inferior cerebellar hemisphere atrophy in extreme preterm survivors is associated with increased disability. Vermis atrophy may follow severe perinatal ischaemic injury-associated cortical, basal ganglia and brainstem lesions should be visible. It is the result of a severe neonatal encephalopathy due to an intrapartum hypoxic event. It has a poor prognosis if there is bulbar weakness or a tendency to aspiration pneumonia.

Nucleic acids contain all the necessary information required for the formation of individual or organism. It is useful for finding causes of several diseases whose causes are unknown till. Chemical nature of nucleic acids Nucleic acids are acidic substances containing nitrogenous bases, sugar and phosphorus. Phosphodiester linkage In polynucleotides, nucleotides are joined together by phosphodiester linkage.

Letters A, C, D, X, Y, Q, R, S are nucleotides Short-hand representation of polynucleotides Since polynucleotide consists of various bases, sugars and phosphates writing a segment of polynucleotide showing structures of bases, sugars with attached phosphates is awkward or highly inconvenient. In compact nomenclature or polynucleotide letters A, G, C and T represents nitrogenous bases adenine, guanine, cytosine and thymine, respectively. A branch at the middle of the verticle line represents hydroxyl bearing 3rd carbon atom of sugar. Another branch at the bottom of Nucleic Acids 405 verticle line represents hydroxyl or phosphate bearing 5th carbon atom of sugar (Figure 16. In this primary structure, letters A, G, C, T stands for nucleotides and sequence is written from left to right. Remember that letters A, C, U, G, T stands for nucleosides in the case of nucleotides. As corollary sum of purine residues is equal to sum of pyrimidine residues A + G = C + T. Using this model, they also suggested a precise mechanism for the transfer of genetic information to daughter cells from parent cells. Two polynucleotide chains are coiled around a central axis in the form of right handed double helix. The bases projects inwards and they are perpendicular to the central axis (Figure 16. If adenine appears in one strand thymine is found in the opposite strand and vice versa. Where ever guanine is found in one strand cytosine is present in the opposite strand and vice versa (Figure 16. Adenine of one strand pairs with thymine of opposite strand through two hydrogen bonds. Complementarity of strands and base pairing are the outstanding features of WatsonCrick model. Apart from hydrogen bonding, the double helix is stabilized by hydrophobic attraction between bases. All the above phenotype characters of living organisms are intimately related to functions of proteins.

Adeno virus (cold virus), Herpes virus and Pox virus are examples for double stranded viruses. The pyrimidine rich strand dissociates from complementary strand and folds back on itself to lie in the major groove and hydrogen bonded to purine rich strand. Intrastrand base paring among complementary bases allows folding of liner molecule. They are methylated adenine, guanine, cytosine and thymine, dihydrouracil, pseudo uridine, isopentenyl adenine etc. Intra strand base pairing between complementary base generates double helical segments or loops.

In conclusion, I want to emphasize that the use of pharmacogenomic testing to guide clinical care is not futuristic. This testing is already a reality, and assessment and application of genomic information will increasingly be an integral part of patient safety and quality of care measures. As the provision of health care transitions from a fee-for-service to a value-of-service environment, these assessments will become even more important. I have touched on only a few of the myriad policy questions and potential approaches to addressing them. Many other questions exist, and more will emerge as genomic information becomes a more routine part of medical care. Who should have access to genomic information, and when should incidental findings be communicated to patients? As genomic medicine becomes integrated into our health care system, so too does the need to develop responsible policies and processes to address the associated social, economic, and information issues.

Sparks Since phenylketonuria was first screened for in the 1960s, newborn screening has expanded to include more than 30 conditions. This commentary provides an update on newborn screening, including the follow-up of abnormal findings, the limitations of such screening, and the ethical questions that screening raises. Each state independently determines which screening tests are done and what follow-up is provided [3]. In addition, states develop their own policies regarding sample collection, laboratory procedures, result reporting, and follow-up programs and education. Regarding consent for testing, most states have mandatory newborn screening with defined opt-out policies for parents [4]. With the expansion of newborn screening, however, states now vary significantly in terms of which disorders are screened for. In 1995 states mandated screening for an average of 5 disorders (range, 0­8); in 2005 this panel included anywhere from 4 to 45 disorders, depending on the state [5]. Screening involves obtaining a sample of blood during the first 24 to 48 hours of life and looking for markers indicative of various disorders. A requirement of such screening is that each disorder being screened for must have a sensitive and reliable marker that can be detected by a simple, inexpensive test. If there is too much phenylalanine in the sample, growth of the bacteria is inhibited, and the sample will appear to be surrounded by a "halo"-an area where there are no bacteria. The diameter of the zone with no bacterial growth is directly dependent on the amount of phenylalanine. If control amounts of phenylalanine are used in the same assay, then the amount of phenylalanine in the tested samples can be quantified. This method was soon applied to maple syrup urine disease (indicated by the detection of elevated leucine levels) and to homocystinuria (indicated by the detection of elevated methionine levels). This methodology allows multiple analytes to be detected in a single blood spot sample. A majority of the disorders screened for require follow-up with confirmatory blood (biochemical) and/or genetic (molecular) testing by physicians who are experts in those disorders. In some states (including North Carolina), screening for cystic fibrosis actually involves genetic diagnostic testing as part of the screening process. If an abnormal result is found, a recommendation for confirmatory sweat testing is conveyed to the primary care provider. Genetic testing is expected to become more commonplace in newborn screening in the future. This will require broader understanding on the part of providers, who may have to engage in potentially complicated and confusing discussions with parents about the newborn screening process and the test results. Research indicates that parents prefer that primary care physicians provide open, honest, informed communication about abnormal newborn screening results. Providers who avoid jargon, recognize parental distress, and encourage questions are rated higher.
