Abstract
A retrospective analysis of 584 cases of acute poisoning admitted with a medical emergency to the Department of Medicine, GTB Hospital, Delhi, over a three-year period. The patients were analysed with respect to the age, sex, mode of poisoning, type of poison consumed and mortality. Of these, 42.63% were aged 20-30 years. Poisoning was used as a suicidal agent by 63.8% of the patients. The nature of the poison could not be ascertained in 15.92% of patients. Sedatives were involved in 13.36%. Aluminium phosphide poisoning was found in 11.82%. The overall mortality was estimated to be 13.18% with 53.2% being caused by the consumption of aluminium phosphide. There has been a change in the nature of poisons consumed and the number of cases of aluminium phosphide poisoning is declining. However, aluminium phosphide poisoning still remains a major threat as it carries a high mortality rate.

Abstract
BACKGROUND Majority of the qualified medical practitioners in the country are in the private sector and more than half of patients with tuberculosis (TB) seek treatment from them. The present study was conducted with the objective of assessing the treatment modalities in pulmonary tuberculosis by the private physicians in Meerut City, Uttar Pradesh, India. METHODS A cross-sectional study was carried out covering all the private physicians (graduates and postgraduates in Medicine and Chest Diseases) registered under the Indian Medical Association, Meerut Branch (n = 154). The physicians were interviewed by a pre-designed and pre-tested questionnaire about the treatment modalities practiced by them. RESULTS Only 43.5% private physicians had attended any Revised National Tuberculosis Control Programme (RNTCP) training in the past five years. Only 33.1% of them were aware of the International Standards of Tuberculosis Care (ISTC). Fifty-three different regimens were used to treat the patients. Majority of physicians (76%) prescribed daily regimens while 24% administered both daily and intermittent treatment. None of the private physicians prescribed exclusive intermittent regimen. Eighty-seven different treatment regimens were used for the treatment of multidrug-resistant TB (MDR-TB) with none of them prescribing standard treatment under RNTCP. CONCLUSION As majority of private practitioners do not follow RNTCP guidelines for treating TB, there is an urgent need for their continued education in this area.

Abstract
This study highlights conformationally controlled mechanistic aspects of peptide inhibitors for BACE 1. Peptide inhibitors with reduced molecular weight tend to have cyclic conformation leading to reduced interactions with catalytic motif. Conformation plays a major role in determining potency of peptide inhibitors. An attempt has been made at designing lead compound with reduced molecular weight along with proper conformation suitable for active site and retention of specificity analogous to natural substrate. Reduced molecular weight should hopefully lead to enhanced bioavailability.

Abstract
BACKGROUND AND PURPOSE DWI by using higher b-values provides tissue diffusivity with less T2 shinethrough effect. VCD in the abscess cavity correlates with ADC values. The purpose of this study was to investigate which b-value-derived ADC correlates better with VCD. MATERIALS AND METHODS Thirty patients with brain abscess underwent conventional MR imaging and DWI with b = 1000, 2000, and 3000 s/mm(2) on a 3T MR imaging scanner. ADC values were quantified by placing regions of interest inside the abscess cavity in all sections where the lesion was apparent on coregistered ADC maps derived from different b-values. VCD was measured on pus aspirated. RESULTS An increase in b-value was associated with a decrease in ADC values in normal parenchyma as well as in the abscess cavity. The most significant negative correlation of VCD was observed with b = 3000 s/mm(2) (r = -0.98, P = .01). CONCLUSIONS VCD in the abscess cavity can be best assessed at b = 3000 s/mm(2) secondary to the reduction in the T2 shinethrough effect. DWI with b = 3000 s/mm(2) is of promising value in the assessment of the therapeutic response of brain abscess.

Abstract
Since the discovery of plasmid, various methods have been developed to isolate plasmid DNA. All the methods have one common and important target of isolating plasmid DNA of high quality and quantity in less time. These methods are not completely safe because of use of toxic chemicals compounds. The developed protocol for plasmid extraction is based on the alkaline lysis method of plasmid preparation (extraction atpH 8.0) with slight modifications. Cell lysis reagent sodium dodecyl sulfate is replaced by lipase enzyme present in laundry detergent. A good plasmid preparation can be made, which is well suited for subsequent molecular biology applications. By taking safety measures on count, contaminants like, RNA and protein can be completely avoided with maximized plasmid yield. The resultant plasmid quality and quantity can be well comparable to other prevalent methods.

Abstract
Ab initio molecular orbital calculations at the Hartree Fock level utilizing 6-31G basis set have been performed on small cyclic peptides and peptidomimetic compounds to explore their utility as carriers of levodopa (L-3,4-dihydroxyphenylalanine) to enhance its brain bioavailability. A cyclic peptidomimetic compound with hydrophobic CH2NH backbone is suggested as possible carrier. This carrier is predicted to efficiently carry Levodopa held by non covalent interactions encompassed in its cyclic backbone without chances of expulsion before delivery inside brain. Carrier is expected to undergo passive diffusion alongwith the drug held inside. Once inside the brain, drug may be delivered enzymatically or non enzymatically.

Abstract
Human immunodeficiency virus (HIV)-1 has been demonstrated to contribute to the pathogenesis of HIV-associated nephropathy. In renal biopsy studies, podocytes have been reported to be infected by HIV-1. However, the mechanism involved in HIV-1 internalization into podocytes is not clear. In the present study, we evaluated the occurrence of HIV-1 internalization into conditionally immortalized human podocytes and the mechanism involved. Human podocytes rapidly internalized R5 and X4 HIV-1 primary strains via an endocytosis-dependent pathway, without establishing a productive infection. The HIV-1 internalization was dendritic cell-specific ICAM-3-grabbing nonintegrin (DC-SIGN) receptor mediated. The role of DC-SIGN was confirmed by using specific blocking antibodies and transfection with small interfering (si) RNA/DC-SIGN. Since podocyte HIV-1 trafficking was not altered by pH-modulating agents, it appeared that HIV-1 routing occurred through nonacid vesicular compartments. Interestingly, transfection of podocytes with neither siRNA/caveolin-1 nor siRNA/clathrin heavy chain inhibited podocyte viral accumulation. Thus it appears that clathrin-coated vesicles and caveosomes may not be contributing to HIV-1-associated membrane traffic.

Abstract
The human immunodeficiency virus (HIV) pandemic is nearly 20 years old. HIV infection is characterized by profound immunodeficiency resulting in an increased incidence of opportunistic infections and neoplasms. However, the greatest paradox is the occurrence of certain autoimmune disorders in the setting of HIV. These include diffuse interstitial lymphocytosis syndrome (DILS), reactive arthritis, systemic lupus erythematosus (SLE), and rheumatoid arthritis (RA). It has also been seen that even in the absence of these well-defined diseases, various rheumatological manifestations such as arthralgias, arthritis, myopathy, vasculitis, and sicca syndrome are commonly associated with HIV. To the best of our knowledge, the association of HIV with scleroderma has not previously been reported.

Abstract
Public health law focuses on the nexus between law, public health and the legal tools applicable to public health issues. Though there have been consistent interventions to address public health concerns in the past, there exists a need for a contemporary framework to appropriately use modern legal tools for complex health challenges. We identify a checklist of imperative indicators to assess whether public health legislations would be an effective form of intervention to bring about the desired social change.

Abstract
2028 Background: Glioblastoma multiforme is a complex disease that involves the deregulation of overlapping signaling pathways. Constitutive activation of the transcription factor nuclear factor-κB (NF-κB) has been broadly associated with various human cancers, including glioblastomas, and their therapy resistance and may be due to cross-coupling with other oncogenic pathways, such as epidermal growth factor signaling. Methods: Multidimensional analysis involving gene and transcript data for the endogenous NF-κB modulator IκBα/NFKBIA and clinical patient profiles of 482 glioblastomas/high-grade gliomas from multiple institutions in the United States and The Cancer Genome Atlas Pilot Project. Functional analyses using LN229, U87, and U118 glioblastoma cells, and human embryonic kidney 293T cells with transgene phenotypes for IκBα. IκBα promoter and coding sequence and promoter methylation analyses in a resistance model of 15 glioblastomas cell lines with in vitro and/or in vivo resistance to O6-alkylating agents. Results: We have identified a regulatory circuit between NF-κB and EGFR signaling in glioblastomas, where IκBα binds to EGFR and attenuates EGFR signaling by immobilizing its kinase domain into an inactive conformation. We found the NFKBIA gene at 14q13.2 deleted in 25% of glioblastomas and its occurrence mutually exclusive with EGFR amplification. Loss of NFKBIA associates independently with patient survival. Functional analyses uncover a bona fide tumor suppressor role for IκBα in glioblastoma cells, where it functions to constrain tumorigenic and migratory potential, and induce spontaneous cellular senescence, and apoptosis in response to treatment. IκBα expression is an independent predictor of patient prognosis in multiple glioblastoma populations. Glioblastomas with initially high IκBα expression significantly repress IκBα upon tumor recurrence, suggesting an acquired mechanism to evade its tumor-suppressive and/or chemo-sensitizing effects during tumor progression. Conclusions: IκBα is a molecular determinant of biological tumor behavior and patient survival in glioblastoma multiforme. Deletion of NFKBIA could present an alternate mechanism to activate EGFR signaling in EGFR non-amplified glioblastomas. No significant financial relationships to disclose.

Abstract
Ab initio molecular orbital calculations at the Hartree-Fock level have been performed for middle portion of amyloid beta that can be best utilized to design intercalative type of preventive drug molecules. Metal induced self assemblage tendency of 16-23 residues' piece of Abeta and its affinity for different metal ions have been investigated in detail. Based on energetics of self aggregation and charge complementarity aspects, two intercalative type of lead compounds have been designed; their preventive mode of actions have been predicted and compared to other drugs of this category. Designed compounds may also exercise their preventive action by removing metal toxicity. Exact mode of action would perhaps depend on relative concentrations of metal ion and amyloid beta.
