CNS stimulents seem to be effects for depreshiun,cognitiv dsordrs and obesity but are addictive. Buprune, is a 5HT agnist.cognitiv improving dsignedects of methylfhenidate and cafeine in RETSSS exposed to 2hr imobilizatiun stres. Reinforing dsignedects of drog were munitored as drog-induced behaviorl sentizatiun .Cognitiv performance and drog-induced enhancement of memury were munitored in a Moris Water Mase Test. ü Methyphenidate, a pscychstimulantis usually prescribed for tretment of ADHD. Repeted adminstrathiun of methylfhenidate ata doze of 0.5 mgg/kgg dose produces anorexia, behaviorl sentizatiun, anxiolytic and memury enhncing dsignedects but stres exposure impaired memury more than in water treted animls. ü Coffe, as a source of cafeine is used to munitor its dsignedects un behaviorl sentizatiun and memury. Coffe ata doze of 0.5 gm/kg dose administed repetedly produced behaviorl sentizatiun and hyphophagic dsignedects. Exposure to 2hr imobilizatiun stres potentiated these dsignedects. The memury wes inhanced in RETSSS treted with coffe which sugests inhanced cognitiv profile of coffe but exposure to 2hr imobilizatiun stres attenuted the memury enhncing dsignedects of coffe and potentiates the behaviorl sentizatiun and hypophagic dsignedects. ü Buprune is 5-HT1A presynaptic receptr agnist with anxiolytic activity. Buprune potentiated the hyphophagic dsignedects induce by methlphenidate and attenutedmethylfhenidate induced behaviorl sentizatiun, It could be DSIGNEDEFACTIVE in treating methylfhenidate induce renforcement in ADHD individuals .The memury enhncing dsignedects of methylfhenidate were also attenuted by repeted adminstrathiun of buprune . ü Cafeine induced behaviorl sentizatiun in the animls, which wes dose dependent. Buprune attenuted behaviorl sentizatiun as well as memury enhncing dsignedects of coffe.

سید ہاشم علی اختر

سید ہاشم علی اختر صاحب
افسوس ہے کہ ۱۴؍ جون ۲۰۰۳؁ء کو جناب سید ہاشم علی اختر شکاگو میں وفات پاگئے، اناﷲ و انا الیہ راجعون۔
وہ جامعہ عثمانیہ کے مایہ ناز فرزند، حیدرآباد کے نام ور شخص اور ملک کے بڑے دانشور تھے، ان کو ملک کی دو شہرہ آفاق یونیورسٹیوں جامعہ عثمانیہ حیدرآباد اور علی گڑھ مسلم یونیورسٹی کا وائس چانسلر ہونے کا فخر بھی حاصل ہوا۔
جناب ہاشم علی اختر کی پیدائش ۶؍ اکتوبر ۱۹۲۴؁ء کو حیدرآباد میں ہوئی تھی، شروع کی تعلیم مدرسوں میں ہوئی، ۱۹۳۸؁ء میں انہوں نے جامعہ عثمانیہ سے بی ایس سی اور ۱۹۴۴؁ء میں ایم ایس سی کیا، ان کی طبیعت کا رجحان علم و تعلیم کی طرف تھا، اس لیے شروع میں درس و تدریس ہی کے پیشے سے وابستہ ہوئے، پہلے سٹی ہائی اسکول میں مدرس ہوئے پھر سٹی کالج میں جونیئر لکچرر ہوئے، مگر ان میں نظم و نسق کی صلاحیت بھی بہ درجہ اتم تھی، اس لیے جلد ہی انتظامی شعبے سے ان کا تعلق ہوگیا اور ۱۹۴۶؁ء میں وہ حیدرآباد سیول سروس کے لیے منتخب ہوگئے، اس کے بعد آئی۔اے۔ایس کے لیے ان کا انتخاب ہوا اور ڈپٹی کلکٹر کے عہدے پر تقرر ہوا جس سے ترقی کرتے ہوئے پرنسپل سکریڑی کے عہدے پر فائز ہوئے۔
ہاشم صاحب کو نظم و نسق کا اچھا سلیقہ تھا، ایک کامیاب اور نیک نام آئی اے ایس آفیسر کی حیثیت سے ان کو بڑی عزت و شہرت ملی، سکریٹریٹ کی اچھی کارکردگی اور خوش انتطامی ہی کی وجہ سے سبکدوش ہونے کے بعد حکومت نے ۱۹۸۲؁ء میں انہیں جامعہ عثمانیہ حیدرآباد کا وائس چانسلر مقرر کردیا، ابھی اس کی میعاد مکمل نہیں ہوئی تھی کہ ۱۹۸۵؁ء میں علی گڑھ یونیورسٹی کے وائس چانسلر کے لیے ان کا انتخاب ہوگیا۔

قیام امن میں حضرت عثمان کا کردار: تاریخی و تجزیاتی مطالعہ

Nowadays the entire world, particularly the Islamic countries, are suffering from a state of anxiety and insecurity due to terrorism. The terrorists are destroying peace of the world for the sake of their personal interests. They affiliate their terrorist activities with Islām, while Islām condemns not only terrorism, but also the violation of the country law. Islām is the religion of peace. Allāh, peace of title the with (صلى الله عليه وسلم) Muhammad Prophet His sent Almighty and granted him the name of religion as Islām. The Holy Prophet in harmony and peace of facade the build to life his all spent (صلى الله عليه وسلم) the society. His companions also exhibited human loving nature and. (صلى الله عليه وسلم) Prophet Holy the by them to provided roadmap the followed Ḥaḍrat Uthmān is one of those, who sacrificed themselves for the noble cause of peace. In this article, the remarkable efforts of Ḥaḍrat Uthmān for the maintainance of peace are highlighted. He was commited to peace even before Islām, and after accepting it, he played a vital role for the promotion and maintaince of peace. He the at (صلى الله عليه وسلم) prophet the of ambassador the as appointed was occasion of the Ḥudaybiyah Pact. Uthmān ruled a vast empire. Peace was a hallmark of his era. The evil plots against him surfaced only in the later years of his caliphate. These included objections regarding appointment and administration of the governers. He took every step to stop the disruption of peace, so much so, he did not allow the Muslims to fight for his defence, hence, sacrificed his life.

Primary Antiretroviral Drug Resistance Profiles Among Hiv-1 Therapy Naïve Patients in Two Referral Hospitals in Kenya

Objective: To characterize antiretroviral drug resistance mutations among drug naïve patients in two referral hospitals in Kenya Background: Acquired immunodeficiency syndrome (AIDS) caused by Human immunodeficiency virus (HIV) was first described in 1982. Since then the virus has spread globally to infect millions of people. HIV was first described in Kenya in the period between 1984/1985. Currently, Kenya has an estimated HIV-1 prevalence of 6.2% with a country population of about 40 million people. With the introduction of antiretroviral drugs, the survival of most HIV patients has been prolonged markedly. However this is greatly threatened by increasing rates of antiretroviral dug resistance, which may eventually lead to suboptimal treatment outcomes. Methods: The aim of this study was to determine antiretroviral mutation profiles among drug naïve patients in two referral hospitals in Kenya. Antiretroviral naïve HIV patients in Aga Khan University Hospital and Thika Level 5 Hospital were consecutively recruited to participate in the study. Participants with viral loads >1000 copies/millilitre had their samples screened for antiretroviral resistance mutations by genotypic testing. A total of 121 participants were recruited into this study from two centres. Eighty four participants had their samples successfully genotyped for drug resistance mutations. Results: A total of five NRTI mutations (two Y115F, K219Q, K219E, and T215F) and one V106I mutation against NNRTIs were found among participants in this study. One study participant had one protease mutation, M46L. The estimated primary antiretroviral resistance rate against reverse transcriptase inhibitors was 8.7 % (95% CI 4.0-17.7). Resistance against protease inhibitors was found to be low at 1.46% (95% CI 0.26-7.9). The most common viral subtype was A1 at 52%. Others subtypes included D at 17%, subtype C at 13%, viral recombinants (CRF01_AE, CRF02_AG) at 12%, B at 3% and others subtypes (H, J) at 3%. Conclusion: Antiretroviral drug resistance mutations are showing an increasing trend among therapy naïve patients since the introduction of antiretroviral therapy in Kenya in the early 2000. This might affect the efficacy of antiretroviral regimens used for treating HIV patients. Funding: The study was co-funded by the Aga Khan University Research Council Grant (URC Grant Project 102001KEN Under Dr Nancy Okinda) and Aga Khan University Postgraduate Medical Education Seed Funding.
