n the clinical chemistry laboratories the advances have been evolutionary but not revolutionary in nature. The recent advances in technology has made it possible to make revolutionary changes. Introduction of Liquid Chromatography – Tandem Mass Spectrometry (LCMS/MS) into clinical laboratories is a revolutionary step. Mass spectrometry is a powerful qualitative and quantitative analytical technique to measure a wide range of clinically relevant analytes. If coupled with gas or liquid chromatography, has expanded analytical capabilities and wider clinical applications. It is an analytical technique that combines physical separation of the mixture of compounds by liquid chromatography.

In the past, several cardiac markers namely, CK, CK-MB, CKMB isoforms, troponins myoglobin were used in the diagnosis and management of cardiovascular disease However, due to lack of VHQVLWLYLW\DQGVSHFL¿FLW\IRUFDUGLDFPXVFOHQHFURVLVIXHOVFRQWLQXHG UHVHDUFK7KHODVWGHFDGHKDVVHHQH[FLWLQJDGYDQFHVLQWKH¿HOGRI cardiac biomarkers used in managing patients with acute coronary syndrome. Biomarker research has broadened our knowledge base, shedding more light on the underlying pathophysiological mechanisms occurring in patients. The criterion required by an ideal cardiovascular biomarker has been progressively changing to an era of sensitive assays that can be used to guide treatment. Recent technological advances have made it possible to rapidly measure even minute amounts of these proteins by means of higher sensitivity assays.

an is a metaorganism. Man’s health and wellbeing is shaped by complex and dynamic interactions within and without Man’s body. Despite the complexity of basic biochemical and physiological processes, dominant and recurring themes in all cultures of the world are descriptions of the sense of feeling well and a wish for a state beyond good health. India’s ancient texts offer graphic descriptions of this state as well as prescriptions of how to achieve and maintain this state and steps to prevent the deterioration of this state. India’s ancient system offer comprehensive well-documented procedures and a holistic logic for this state of wellness. Are these and other rules which have guided many and offered health beyond good health for centuries also valid for contemporary living now and for the future? What might these indicators look like when viewed through the eyes of contemporary clinical biochemical and molecular descriptors?

The IFCC’s committee on Reference Intervals & Decision Limits (C-RIDL) has spearheaded a number of initiatives towards harmonization of reference ranges in recent years. Most prominent amongst these are publication of protocols & standard operating procedures for common use in multicentric studies on reference values, the Asian project for collaborative derivation of reference intervals for standardized & non-standardized analytes and the global multicentric study on reference values. Though all of this work is path breaking & has already laid the foundation for a multi-stakeholder collaboration, thought also needs to be given to the scope of building open databases/registries in order to enable more number of diagnostic laboratories & clinicians to participate in this initiative.

GS15 Molecular basis of the preventive effect of amla ((PEOLFD RI¿FLQDOLV) on metabolic derangements in an experimental model of postmenopausal metabolic syndrome Bobby Zachariah JIPMER, Pondicherry, India Objectives: Increased fructose consumption worsens the already raised cardiovascular disease risk in postmenopausal women. This study explored the potential mechanisms by which amla reduced hypercholesterolemia and hypertriglyceridemia and prevented fatty liver in fructose fed postmenopausal rats. Methods: Sham operated and ovariectomized rats were put on either chow or high fructose diet. They were further divided into groups with or without amla. After 18 weeks of treatment, the livers were harvested and subjected to western blot and histological analyses. Results: Fructose fed rats developed fatty liver and amla prevented this. Amla increased the protein expression of liver farnesoid X receptor (FXR) and liver X receptor (LXR), key proteins involved in lipid metabolism. In fructose group, amla produced an exceptional rise in LXR and Insulin induced gene-2 (Insig-2) which prevented the maturation of Sterol regulatory element-binding protein-1(SREBP-1) and Steroyl CoA desaturase 1responsible for triglyceride synthesis. Amla also increased the protein expression of ATP binding cassette transporter A1 involved in high density lipoprotein (HDL) synthesis as well as low density lipoprotein (LDL) receptor responsible for uptake of LDL cholesterol. Besides this amla increased the protein expression of peroxisome proliferator activated receptor ? (PPAR ?) involved in ? oxidation of fatty acids. Conclusions: Amla was highly effective in preventing non-alcoholic fatty liver disease (NAFLD), an independent risk factor for CHD in postmenopausal rats. The property of amla to modulate some of the key proteins involved in lipid metabolism promises its usefulness as a preventive agent for dyslipidemia and hepatic steatosis.

ass newborn screening is practiced in most Western countries using tandem mass spectrometry. It is done for common disorders detected in their population like phenylketonuria, maple syrup urine disease, organic acidurias, galactosemic, hyperhomocystenimia etc. In India, prevalence of inborn errors of metabolism is very high. There is high morbidity and mortality necessitating urgent steps for control. Inherited diseases can be controlled only if they are detected at an early stage and by counseling, including family prenatal counseling. Even now, in India there is no government sponsored program for newborn screening, even though many centers are performing out of their own interest and a few states are also performing. The major limiting factor is cost. There is no need to perform tandem mass spectrometry in our country. Our studies suggest that urine screening tests can be used, and implemented as a preliminary tool for mass screening programs. Babies detected to have abnormalities can be followed up by advanced testing, if necessary, free of charges, at advanced centers.

NASH is projected to be the leading cause of liver transplantation by 2020 [6]. By now, the Metabolic Syndrome (MS) is a common term which includes central obesity, hypertension, decreased serum HDL and elevated triglyceride with insulin resistance as the central pathophysiological factor. NAFLD/NASH is now considered to be the hepatic component of metabolic syndrome. It is associated with obesity as well as diabetes and could be not only a result of insulin resistance (IR) and metabolic syndrome but rather a major contributor to systemic IR. Diagnosis of NAFLD is based on liver function tests particularly abnormal serum aspartate transaminase (AST) and alanine transaminase (ALT) levels in most of the studies [7, 8]. :HFRQGXFWHGWKLVVWXG\ZLWKDQDLPWRH[SORUHWKHSUR¿OHRIOLYHU enzymes in patients with NAFLD in eastern India and also to look at the possibility of histopathological correlation, if any, with the transaminase levels. Results and discussion : In our study, patients with NAFLD had higher BMI, higher Fasting plasma glucose (FPG), higher serum triglycerides, lower serum HDL, higher serum AST and ALT, higher serum insulin and insulin resistance (HOMA IR) than controls. Most of the previous studies too have shown that NAFLD is increasingly associated with obesity, hyperglycemia, dyslipidemia, high serum AST and ALT [9,10,11,12].

NASH patients have higher risk for liver and non-liver related mortality than patients with simple steatosis. However it is not possible to get liver biopsy in every patient of NAFLD due to its high incidence. So it is important to stratify the NAFLD population and identify which subgroup needs more attention and regular follow up. NAFLD patients with transaminitis and higher values of HOMA IR are more prone for metabolic syndrome and hence cardiovascular disease. There are several limitations of this study. Being an observational study it is not devoid of selection and confounding bias. Also there may have been a selection bias for patients undergoing liver biopsy. Subjects with higher serum transaminases and insulin resistance may have been more often referred for liver biopsy. However, over half of the patients who underwent liver biopsy had normal transaminase values. Besides it is believed that trans abdominal ultrasound which was used as the screening test for fatty liver can reliably diagnoses NAFLD only if steatosis is >33%. Patients with mild steatosis less than 33% can be missed by sonography.

The development of T2DM depends on the involvement of genetic and environmental factors.

Folate Metabolism and Genetic Aberrations Folate metabolism is also known as one-carbon metabolism, which involves sequential transfer of one-carbon moiety from one substrate to another to form several crucial metabolites. S-adenosylmethionine (SAM) is the universal methyl group donor for a variety of methyltransferases, resulting in the methylation of substrates such as nucleic acids, lipids and proteins. The transmethylation pathway is present in most mammalian tissues and SAM is generated via the activation of methionine by methionine adenosyltransferase. All SAM-dependent methyltransferase reactions result in the production of S-adenosylhomocysteine (SAH), which can subsequently be converted to HCY by SAH hydrolase. HCY may be remethylated back to methionine by either folate-dependent or folate-independent

For folate-dependent remethylation, the B12dependent enzyme methionine synthase utilizes a methyl group from PHWK\OWHWUDK\GURIRODWH%HWDLQHKRPRF\VWHLQH6PHWK\OWUDQVIHUDVH catalyzes the folate-independent remethylation of HCY using betaine, a methyl group donor derived from choline oxidation. Hepatic folate, methyl group and HCY metabolism are interrelated that when disrupted are associated with numerous pathologies. Maintenance of normal methyl group and HCY homeostasis are depending on the balance between SAM-dependent transmethylation, which utilizes methyl groups and produces HCY; remethylation of HCY back to methionine by folate-dependent and -independent mechanisms; and HCY catabolism via the transsulfuration pathway.

oxic heavy metal lead is recognized as number one environmental poison and the top hazardous material in any form to all system of life known till date. Over one third population of the developing world is found having unacceptable level of lead in blood. Amongst this the most effected are children and women in their reproductive age. While over one third of children during growth are constantly losing their cognitive function pre menopausal women are having problems related to their musculoskeletal and reproductive system. In developing countries efforts are made to understand the gravity of situation and newer policies are being evolved. Developed countries are on the other hand are shifting their problem to developing counWULHV7KLVFRQÀLFWLVFDXVLQJPDQ\HQYLURQPHQWDODQGKHDOWKUHODWHG issues.

Energy dysregulation being the common denominator in metabolic disorders, the over-nourished modern man probably suffers from chronic under activation of AMPK. Additionally, AMPK is an upstream regulator of Nrf2 (Nuclear factor erythroid-derived 2) a potent antioxidant activator and inducer of cytoprotective responses to oxidative stimulus.

Molecular diagnostics has got a wide range of applications in many medical specialization, such as oncology, cardiovascular disease biology, infectious disease, pharmacogenomics, human leukocyte antigentyping etc. The globalization of molecular biology tools has made the system more common. The invention of single handheld diagnostics devices helps in making molecular diagnosis more user friendly. The single device system has made the diagnosis more precise. The reduction of errors and contamination has made this system gain reputation as a new generation diagnostic platform. In vitro biological assays such as PCR, Real time PCR, ELISA etc. has made the medical diagnosis very fast with very less errors. In older days’ blood culture, bacterial culture etc. used to take a minimum of two days to bring out the test result. Currently, with molecular diagnostics, the test results are available within hours.

lant phytochemicals and their antioxidant properties have been a conventional resource to counter radiation induced oxidative stress. Their role as free radical scavengers has contributed to the dose modifying effect and also reduced the radiation induced immune suppression. The present study summarizes the effects of numerous plant resources and depicts their role in reducing the radiation induced oxidative stress. Oxidative stress is a state of imbalance

between the oxidants and reductants which lead to a chain of events that can have deleterious impact on the health and survival of the organism. The study involved the roots of Nardostachys jatamansi, pod of Tamarindus indica, leaves of Carica papaya, Cocos nucifera water, seed of Linum usitatissimum and peels of Punica granatum fruit. These plant resources were studied for their invivo HI¿FDF\ to counter radiation induced antioxidant changes. Further the dose reduction factor was estimated by subjecting mice to radiation after their respective plant extract intervention. The results indicated reduced lipid peroxidation and maintenance of antioxidant enzyme levels near to that of normal. The survival of mice was also found to be prolonged after the herbal extract intervention before irradiation. Thus, the results indicate a diverse role of these plant sources in targeting a wide range of complications that may arise due to oxidative stress. Hence these plant materials could be used as a natural dietary antioxidant supplement or an adjuvant in radiotherapy and chemotherapy that may contribute directly or indirectly in protecting the normal cell damage.

Results: Endosulfan was found to decrease in cell viability in a dose dependent manner. Endosulfan exposure also led to dose-dependent increase of ROS and depletion of GSH levels in HK-2 cells. In the presence of antioxidants n-acetylcysteine or glutathione inhibition of ROS generation observed. The activity of caspase-3 was observed increased with the exposure of increased concentration of endosulfan. Results from comet assays revealed that endosulfan showed the ability to increase the levels of DNA strand breaks in HK-2 cells. Conclusion: The results indicating that oxidative stress precedes cytotoxicity and genotoxicity, and plays an important role regarding the mechanisms involved in endosulfan induced nephrotoxicity. The results obtained may be extrapolated towards possible mechanism of renal dysfunction in CKDu patients having increased level of endosulfan.

treatment decreased the colony formation ability of breast cancer cells implicating its anti-proliferating property. During mechanistic studies we found that TcCF induced growth inhibition was a consequence of its ability to induce apoptosis in these cells. More interestingly we also observed that TcCF treatment increased the intracellular levels of reactive oxygen species (ROS) in these cells. Inhibition of ROS reversed TcCF induced apoptosis in breast cancer cells thereby emphasizing the role ROS in TcCF induced breast cancer cell death. Furthermore, apart from ROS generation TcCF treatment altered the expression of pro and anti-apoptotic factors in both the breast cancer cell lines favoring the pro-apoptotic condition. /DVWO\ RXU +3/& DQDO\VLV IRU ELRFKHPLFDO FRPSRQHQW HVWLPDWLRQ showed the presence of pharmacologically active compounds like rutin and quercetin with which can be attributed to the anti-cancer property of TcCF against breast cancer cells.

FO23 Estimation of thyroid function tests and type 2 deiodinase gene polymorphism in patients with type 2 diabetes mellitus Smita Gawandi, Savita Kulkarni, J. Kumarasamy, S. Cherian BARC Hospital, Mumbai Introduction: Thyroid diseases (TD) and Diabetes Mellitus (DM) are the two most common endocrine disorders. A variety of TD may coexist and interact with DM and its presence is left undiagnosed as their symptoms overlap. The undiagnosed TD can interfere in the diabetes management and increase the related complications warranting regular screening of TD in DM. Further, as Thr92Ala polymorphism in type 2 deiodinase gene is one of the factors linked with co-existence of DM and TD, its screening in diabetic patients will help in determination of their susceptibility towards development of TD. Materials and Methods: TFTs viz. T4, T3, TSH, FT4, AMA and insulin levels were estimated in diabetic patients (n=66) as well as in controls (n=50) by using RIA and IRMA kits. The genomic DNA was extracted from the diabetic patients for screening of Thr92Ala JHQHSRO\PRUSKLVP3&5LVFDUULHGRXWIRUGHWHFWLRQRI7KU$OD polymorphism. Results and Conclusion: Forty-four percent of the diabetic patients showed abnormal TFTs.

Hegde Medical Academy, Mangalore Introduction: Hyperlipidemia is a main factor responsible for coronary artery disease. Atorvastatin, commonly used competitive inhibitor of HMG-Co-A reductase, is known to reduce the levels of LDL, triglyceride and increase the levels of HDL. Coriandrum sativum (Coriander) belongs to the Apiaceae family, has hypolipidemic, antidiabetic, anti-oxidant properties. Triton WR1339 has been used by several studies to induce hypercholesterolemia in animals which acts on both synthesis and excretory phase. Aim and Objectives: To compare the hypolipidemic effect of Coriandrum sativum and Atorvastatin in Triton-induced hyperlipidemic rats.

Sachdev, Nikhil Tandon, Ambuj Roy, Santosh Bhargava, Bhaskar Singh AIIMS, New Delhi Introduction: Suboptimal nutritional during intrauterine life is a critical determinant of risk of CVD, hypertension and T2D in adulthood. Accelerated oxidative stress and reduced antioxidant defense in low birth weight individuals followed by postnatal rapid growth can cause telomere dysfunction, which is associated with age related disorders. It is likely to throw light on the relationship of early growth to later diseases. Objectives: We tested the hypothesis that growth retardation during fetal period and postnatal rapid growth is associated with telomere attrition in leukocytes, which may link to the developmental origin of adult chronic disease.

Oxidative stress, observed in IUGR, is also an initiator of these disease processes. Oxidative stress during IUGR and postnatal growth can cause telomere dysfunction which can trigger senescent pathways like the p53-p21 or the p16.

However, underlying molecular and cellular mechanisms of pathogenesis remain largely unknown. Here, we investigated the angiogenic gene expression in patients with NAFLD and also studied their correlation with the clinical parameters of these patients. The functions of the correlated genes were further analyzed by in vitro studies. Patients and Methods: Microarray differential gene expression analysis in liver tissues of healthy controls (Gr1, n=7) and patients with steatosis (Gr2, n=7), and patients with non-alcoholic steatohepatitis (Gr 3, n=8) using affymetrix gene chips were conducted. Among all 556 differentially expressed genes (DEGs), a subset of about 22 DEGs associated with lipid metabolism, hypoxia and angiogenesis were selected for further studies.

Perspectives: The role of the tutor in small group teaching is of paramount importance to the success of SGT and the tutor is more of a facilitator than a didactic lecturer. Some may see this as diminishing the role of a teacher but in reality it facilitates the empowering of both the teacher and the learner.

espite the fact that automation in instrumentation has transformed clinical biochemistry, a large number of hospitals, especially in the government sector is still resorting to manual handeling of biochemistry data. The major problem faced by these laboratories relate to dispatch of results to the clientele. There is a VLJQL¿FDQWWLPHJDSEHWZHHQJHQHUDWLRQRIWKHUHVXOWVDQGWKHSDWLHQW clinician actually getting them. Hence it was proposed to digitilise the biochemistry reports adn send them to the patients as SMS. We present our one year experience of doing so. Material and Methods : Digitilisation of biochemistry reports was done by entering the results manually in an MS Access database. This module was developed inhouse. The module was then linked with WKH606GLVSDWFKPRGXOH)RUWKLVZHXVHGWKHVHUYLFHVRID¿UPIRU DQ¿UP0V9¿UVW7HFKIRUDFRVWRI5V3DWLHQWUHSRUWVZDV entered manually along with their mobile number. Once the reports were validated, the same were sent automatically to the patients by the module. Results : A total of 56300 reports have been sent so far (approx 165 SMS per day). The turn around time from generation of reports to dispatch of results was brought down from one day to a few hours.

FO65 Role of beta-2-microglobulin-`2m (correlated with CD56 expression) in multiple myeloma Geeta Rathnakumar, Meera Ghadge, Nitin Inamdar, Bhoopal Shinde Tata Memorial Hospital, Parel, Mumbai Background: Multiple myeloma (MM) is a type of blood cancer where uncontrolled cell division of plasma cell takes place, producing monoclonal antibodies in greater concentration. The simplest measure of prognosis in MM is based on `2m and albumin. higher levels of `2m and lower levels of albumin are associated with a poorer prognosis. `2m is a small membrane, low molecular weight protein (11,800 Dalton) associated with the heavy chains of class I major histocompatibility complex proteins and is, therefore, on the surface of all nucleated cells. Expression of CD56 is commonly used to identify abnormal plasma cells, since plasma cells from the bone marrow of healthy individual are negative for the CD56 antigen. 6HUXP 3URWHLQ (OHFWURSKRUHVLV LV FRPPRQO\ XVHG WR LGHQWLI\ patients with multiple myeloma and other disorders of serum protein.

Conclusion: There are no reports of use of cheek epithelium to study association of trans fatty acids with MI. In our study population, 18:2 trans fatty acid measured in cheek epithelium was associated with coronary artery disease. Use of cheek epithelium for objective assessment of trans fatty acid to carry out association study opens up many possibilities. 18:2trans, which is abundant in hydrogenated oils, may confer higher cardiovascular disease risk in Indians.

During pregnancy at different trimesters there are number of hormonal and metabolicchanges occur, like, rise in thyroxine binding globulins (TBG), alteration of iodine metabolism,increase in human chorionic gonadotropin (bHCG), haemodilution etc. which affects thyroid hormone level.Therefore reference intervals (RI) for thyroid hormones in pregnant population require to be established separately from general population for proper assessment of thyroid function during pregnancy. Aims and Objectives : Reference intervals (RIs) of serum thyroid stimulating hormone (TSH)total T4and total T3 were determined in healthy pregnant women by enzymelinked immunosorbent assay (ELISA) technique after partitioning them into three trimesters. Material and Methods: This study was conducted in the zonal level army hospital. The reference population was chosen from a study population ofpregnant females of army dependents by applying strict inclusion and exclusion criteria. The assays were done using proper quality control measures.

PO98 Role of free radicals and antioxidant in low backache K. Vignesh Babu, S. Venkata Rao Introduction: Low backache may be caused by muscle or ligament strain, bulging or ruptured disks, Osteoarthritis, skeletal irregularities, or Osteoporosis etc. The pain may originate from the muscles, nerves, bones, joints or other structures in the spine. Antioxidants acts as scavengers, suppress the formation of free radicals and oppose their activities. Aims and objectives: (1) To evaluate levels of Malondialdehyde (MDA) and Vitamin C (Ascorbic acid) in low backache patients.(11) To correlate relationship between MDA, Vitamin C in low backache patients Materials and methods: ORZEDFNDFKHSDWLHQWVQ DQG normal healthy controls with average age 45yrs (30-60yrs) were selected for the study.

Background: Type 2 Diabetes mellitus (T2DM) is a major health problem worldwide. Increased hepatocellular glycogen accumulation and excess free fatty acids that occurs in condition of hyperglycemia were found to be directly toxic to the hepatocytes and might result in the leakage and elevation of aminotransferases, ultimately leading to liver disorders. Thus the study taken up to study the liver function parameters in T2DM patients.

This disorder is a leading cause of maternal and fetal morbidity and mortality. It is seen that placental oxidative stress is involved in the etiopathogenesis of preeclampsia. This oxidative stress induces endothelial cell injury which in turn causes lipid peroxidation. Although the lipid peroxidation is counteracted by the action of several antioxidants. Aim: The aim of this study was to elucidate the changes in the level of lipid peroxidation markers and antioxidants in preeclamptic pregnant women that may contribute to the pathogenesis in preeclampsia. Material and Methods: 7KLUW\ ¿YH SUHJQDQW ZRPHQ clinically diagnosed as preeclampsia were taken as subjects and an equal number of age matched, parity matched and gestation age matched healthy normotensive pregnant women were taken as controls for the study.

PO170 Comparison of serum anti mullerian hormone and thyroid stimulation hormone in women with high TSH levels Arpita Chakraborty, Vinutha R. Bhat, Krishnananda Prabhu R.V. Department of Biochemistry, Kasturba Medical College, Manipal, Manipal University, Manipal Introduction: AMH (Anti Mullerian Hormone), a known biomarker of ovarian function is secreted by the follicles. In women who suffer from a condition known as diminished ovarian reserve (DOR), this can often be quite low, indicating that there are few remaining follicles within the ovary. Measurement of serum TSH is generally considered the best screening test for thyroid disease. Thyroid dysfunction and autoimmune thyroditis are associated with fertility problems in women of reproductive age. So this study was designed to compare serum AMH values in women with high TSH levels. Objective: To compare the levels of serum AMH and TSH in women with high TSH levels. Materials and Methods: After receiving ethical clearance from Institutional Ethical Committee 374 patients with AMH values were taken. Out of which 37 reports with both AMH and TSH tests in Kasturba Medical College, Manipal were considered for this study. All the reports were retrieved from Laboratory Information System (LIS) under supervision of Laboratory Incharge Dr. Ravindra Maradi under proper anonymization Comparison and correlation of variables were done using appropriate statistical tests.

Case Report: A 60 year old of Carcinoma left buccal mucosa, reported to the hospital with pain and edema over the left side of the face for one month. The patient was given tablet Ranitidine at the time of admission. Half an hour later the patient developed itching all over the body associated with breathlessness. The pulse rate dropped GRZQEORRGSUHVVXUHZDVQRWUHFRUGDEOHDQG322 was 60% without oxygen. The patient was put on oxygen with Inj Chlorpheniramine IV stat and Inj Hydrocortisone IV stat. After half an hour normal pulse rate and blood pressure was achieved.The incidence of anaphylactic reaction to H2 receptor blockers (cimetidine and ranitidine) and proton pump inhibitors (lansoprazole, omeprazole and pantoprazole) together has been reported to be 0.2-0.7%. Conclusion:$FFRUGLQJ WR WKH:+280& VFDOH WKH FDXVDOLW\ ZDV found to be probable. Awareness of this rare adverse reaction to ranitidine, a commonly used drug, could help in early recognition of the event if faced suddenly.

PO192 YAP, The transcriptional co-activator in platelets Pavalaveelzi.C.M, Debabrata dash Institute of Medical Science, Banaras Hindu University, Varanasi Introduction: Platelets are enucleate cells with a life span of 10-12 days, which play central roles in hemostasis and pathological thrombus formation associated with ischemic heart diseases and stroke. Recently, the Wnt-`-catenin signaling pathway and sonic hedgehog signaling have been shown to function in human platelets. These being developmental signals, have prompted us for the study of another developmental signaling: ‘Hippo’ in human platelets. Lats1, a kinase is one of the core components and YAP (Yes associated protein) is a downstream transcription co-activator of many genes. YAP is active in dephosphorylated and inactive in phosphorylated form (pYAP). Aims and Objectives: To identify the presence of Hippo signaling in platelets and to study the regulation of YAP in platelets. Materials and Methods: Human blood samples were collected from healthy donors after taking proper consent.Washed platelets were prepared. Thrombin was used as agonist for platelet activation.

Introduction: Amphetamine and Benzodiazepine are a group of compounds that are abused in many regions around the world. According to the world drug report conducted in 2012 about 5% of the world’s adult population are estimated to have used an illicit drug atleast once. Drugs of abuse can alter a person’s thinking and judgement, leading to health risks, including addiction, drugged driving and infectious disease.These drugs also tap into the brains communication system and disrupt the way nerve cells normally send, receive and process information. Amphetamine is a stimulant that affects certain chemical in the brain and nerves that contribute to hyperactivity and impulse control. Benzodiazepine is a psychoactive drug that enhances the effect of neurotransmitter gamma amino butyric acid (GABA).
