Backgound: Laparoscopic cholecystectomy has revolutionized the world in the surgical management of benign gallbladder disease. However, for any procedure to learn properly, anatomy becomes a major concern. Aims and Objectives: We present a point, a convenient site, speedily accessible by our maneuver of placing epigastric port on the patient. Materials and Methods: This is an outcome of an observation with the prospective study of 100 patients irrespective of age, sex, body habitus and severity of gallstone disease. Our point for epigastric port satisfies all the criteria for an ideal port. Results: Our general observation with majority of patients with this point specific epigastric port placement was that it is easy to locate, needs less thrust on trocar for creation, stays on the linea alba, is easily maneuverable facilitates safe, easy and speedy dissection, causes less portal bleeds and is easy to angulate towards the right of falciform ligament. Conclusion: The point specific epigastric port conveys many benefits to the operating surgeon in terms of easy location, adds safety and speed to the procedure, causes less portal bleeds, needs less thrust and is easy to angulate to the right of the falciform ligament adding technical ease to the surgeon. It is easy to be learnt, taught and practiced by the young surgeons.

Abstract: Objective: To compare the clinical, echocardiographic and angiographicvariables after PTMC in patients of mitral stenosis having echo score < 8 and $ 8. Place of study: Cardiology wardand echocardiography department of the Punjab Institute of Cardiology, Lahore. Duration of study: The study wasconducted from 15 of January 2006 till 30 th th of July 2006.Study Design: It was a comparative study. Materials &Methods Two hundred consecutive patients of mitral stenosis undergoing PTMC were studied. Patients were dividedin to two groups. Group I consisted of patient having echo score <8, while Group II contained patients having echo score$8. Results:The immediate clinical follow-up of 200 patients who underwent PTMC procedure was studied. Patientswere divided into 2 groups, Echo-Sc <8 (n=136) and Echo-Sc$8 (n=64). PTMC resulted in an increase in mitral valvearea from 1.0±0.3 to 2.0±0.6 cm2 in patients with Echo-Sc<8 and from 0.8±0.3 to 1.6±0.6 cm2 in patients with Echo-Sc$8 (P<0.0001). Procedural success was 83.5% for the overall group, with patients with Echo-Sc <8 having a higherprocedural success (93.4% versus 62.5%; P<0.0001). Thirty three (16.5%) patients had unsuccessful procedures.There was 1(0.5%) in-hospital death. Severe post- PTMC MR ($3 grade) occurred in 19(9.4%) patients, with grade IIIin 12 (6%) and grade IV in 7(3.5%). Emergent MVR was required in 3(1.5%) of 200 patients. Pericardial tamponadeoccurred in 2(1%) patients. Thromboembolic events (stroke) occurred in 2(1%) patients in the overall population. Finally1(0.5%) patient developed complete atrioventricular block. Conclusions: Patients with echo score less than 8 havea favourable outcome in terms of procedural success and post procedure complications as compared to patients withecho score $8.

Abstract: A sample of Akhnoor meteor crater, which fell on 2nd January 2009 in Jammu District, Jammu & Kashmir, India, has been analyzed for ele-mental composition by Spectroscopic tech-niques. Concentrations of 17 major, minor and trace elements were determined. The authentic-ity of the meteorite sample was established by comparing its composition with those of stan-dard meteorites/chondrite. The classification of the sample has been made by comparing the abundances and concentration ratios of ele-ments with other known meteorites.
Awareness regarding female breast cancer in Kashmiri males - A study
Sajad Ahmad Salati,Ajaz Rather
Online Journal of Health & Allied Sciences , 2010,
Abstract: Breast cancer is a major killer disease in females globally and in developing regions, where the early cancer detection facilities are unavailable, prognosis is even worse. Awareness about this disease can lead to early detection and thereby decrease the morbidity and mortality. A self designed questionnaire was used to study the level of awareness regarding breast cancer among males. The questionnaire had 15 questions and on the basis on score attained, the subjects were classified as having poor, average or good breast cancer awareness. Out of 624 participants, 555(89%) had poor breast cancer awareness and 47(7.5%) had average awareness. Only 22 (3.5%) had good awareness about breast cancer. The level of awareness regarding female breast cancer in Kashmiri males is very low. Measures need to be taken to spread awareness about this disease in males so that they can play a vital role in early detection of this disease.
The dynamics of competitive learning: the role of updates and memory
Ajaz Ahmad Bhat,Anita Mehta
Physics , 2011, DOI: 10.1103/PhysRevE.85.011134
Abstract: We examine the effects of memory and different updating paradigms in a game-theoretic model of competitive learning, where agents are influenced in their choice of strategy by both the choices made by, and the consequent success rates of, their immediate neighbours. We apply parallel and sequential updates in all possible combinations to the two competing rules, and find, typically, that the phase diagram of the model consists of a disordered phase separating two ordered phases at coexistence. A major result is that the corresponding critical exponents belong to the generalised universality class of the voter model. When the two strategies are distinct but not too different, we find the expected linear response behaviour as a function of their difference.Finally, we look at the extreme situation when a superior strategy, accompanied by a short memory of earlier outcomes, is pitted against its inverse; interestingly, we find that a long memory of earlier outcomes can occasionally compensate for the choice of a globally inferior strategy.
Congenital Intranasal Glioma
Sajad Ahmad Salati,Ajaz Ahmad Rather
Case Reports in Surgery , 2011, DOI: 10.1155/2011/175209
Abstract: Congenital midline swellings of nose are encountered rarely, and nasal gliomas constitute about 5% of such lesions. Various theories have been suggested to explain the pathogenesis. Imaging preferably by MRI is mandated to study the extent and to rule out intracranial extension. Treatment is complete excision, and the approach depends upon the extent of the lesion and availability of expertise. We present the management of one such case of congenital intranasal glioma without any intracranial extension that presented as a septal polyp.

Pakistan Journal of Biological Sciences , 2004,
Abstract: Five phytopathogenic strains namely, Xanthomonas oryzae NA1, Xanthomonas citri NA2, Pseudomonas andropogonis NA3, Erwinia carotovora NA4 (isolated from diseased fruits and vegetables) and Agrobacterium radiobacter NA5 (isolated from pepper rhizophere) were identified on morpho-cultural and biochemical considerations. API 20 E and API 20 NE kits were used to confirm the identification. All isolates were screened for bacteriocinogenic activity against phytopathogenic bacteria. Accordingly, only two strains i.e. Erwinia carotovora NA4, Agrobacterium radiobacter NA5 were found to produce bacteriocin. These bacteriocins are designated as erwiniocin NA4, agrocin NA5, respectively. Both the producer strains have shown antibacterial activity against closely related strains. The activity potential of erwiniocin NA4 was calculated as 160AU mL-1 while that of agrocin NA5 was 80AU mL-1. The effect of temperature variation and pH on erwiniocin NA4 and agrocin NA5 was also checked and both were found activity resistant at 100 C for 10 min and pH range 2-14. Erwiniocin NA4 was also found resistant to autoclaving while bioactivity of agrocin NA5 was lost after similar treatment.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0025048
Abstract: Competition between synapses arises in some forms of correlation-based plasticity. Here we propose a game theory-inspired model of synaptic interactions whose dynamics is driven by competition between synapses in their weak and strong states, which are characterized by different timescales. The learning of inputs and memory are meaningfully definable in an effective description of networked synaptic populations. We study, numerically and analytically, the dynamic responses of the effective system to various signal types, particularly with reference to an existing empirical motor adaptation model. The dependence of the system-level behavior on the synaptic parameters, and the signal strength, is brought out in a clear manner, thus illuminating issues such as those of optimal performance, and the functional role of multiple timescales.

Abstract: Sixty bacterial strains (isolated from soil near different petrol pumps of Karachi city) were screened for hydrocarbon degradation. They were identified on the basis of morpho-cultural and biochemical characteristics and were found belonging to different genera including Staphylococcus, Corynebacterium, Bacillus, Proteus, Pseudomonas, Klebsiella and Escherichia. Four solid hydrocarbons including biphenyl, camphor, phenanthrene and naphthalene and four liquid hydrocarbons i.e. benzene, toluene, octane and heptane were used in this study. In the case of solid hydrocarbons a total of 17% degraded biphenyl, 8% degraded camphor, 8% degraded naphthalene and 10% degraded phenanthrene. In case of liquid hydrocarbons about 57% were able to degraded benzene, 55% degraded toluene, 48% degraded octane and 33% degraded heptane. About 89% isolates degraded both solid and liquid hydrocarbons while 11% could not degrade any of them. In order to locate the genes responsible for hydrocarbon degradation, curing experiments were performed using physical agent i.e. elevated temperature and the chemical agent i.e. acridine orange. Results of these experiments indicated that the genes are plasmid born. In vivo direct gene transfer (bacterial conjugation) experiments were also performed and it was shown that hydrocarbon-degrading plasmid genes are stably transferable to the competent recipient cells.
