احمد تیمور پاشا

مرحوم احمد تیمور پاشا
مصر کے ان جدید تعلیم یافتہ اصحاب میں، جنھوں نے گزشتہ ربع صدی میں عربی علم ادب اور اسلامی علوم و فنون کی بیش ازبیش خدمت انجام دی، ایک ہستی احمد تیمور پاشا کی ہے، افسوس ہے کہ انھوں نے گزشتہ ماہ اپریل میں وفات پائی، ان کی مفید تالیفات کے علاوہ وقیع علمی مقالات مصروشام کے ممتاز رسالوں میں شائع ہوتے رہتے تھے اور معارف نے بھی ان کے مضامین ایک سے زیادہ مرتبہ اپنے صفحات میں پیش کئے۔
احمد تیمور پاشا نومبر ۱۸۷۱؁ء میں مصر کے ایک متمول کرد خاندان میں پیدا ہوئے، یہ خاندان محمد علی پاشا کے عہد میں موصل سے مصر میں آکر آباد ہوا اور اس کے مورث اعلیٰ تیمور بن محمد بن اسمٰعیل بن کرد محمد علی پاشا کے دورِ حکومت مصر میں کے دست راست تھے۔
احمد تیمور پاشا ابھی چند ہی دن کے تھے کہ ان کے والد اسمٰعیل تیمور پاشا کا انتقال ہوگیا اور ان کی تربیت ان کی شاعرہ و ادیبہ بہن عائشہ نے کی، انھوں نے ان کو بچپن ہی میں ایک فرانسیسی مدرسہ ’’مارسیل‘‘ میں داخل کردیا، چند سال کی تعلیم و تربیت کے بعد جب انھیں عربی علم و ادب سے زیادہ شغف ہوا تو فرانسیسی مدرسہ سے نکل کر گھر ہی پر عربی علوم و آداب کی باقاعدہ تحصیل شروع کی اور اس عہد کے مشہور اساتذۂ مصر کے سامنے زانوے ادب تہ کیا، چنانچہ ان کے اساتذہ کی فہرست میں مصر کے ممتاز فاضل شیخ رضوان بن محمد مغلاتی، شیخ حسن طویل، شیخ محمد محمود ترکزی شنقیطی، شیخ محمد عبدہ اور علامہ طاہر جزائری وغیرہ ہیں، انھیں اساتذہ سے علوم عربیہ صرف و نحو، فقہ، منطق، حدیث اور علوم قرآن میں مہارت حاصل کی اور ان علوم کے ماسوا فرانسیسی زبان میں خاص دستگاہ پہلے حاصل ہوچکی...

Issues of Ethnic Diversity and Just Development in Pakistan with a Special Focus on the Seraiki Ethnic Group

Ethnicity implies the sense of belonging together as the cultural group in a given society. It is a complex combination of racial, cultural and historical characteristics by which people differentiate themselves from other groups. This research envisages the genesis and the evolution of ethnicity as a political concept, the problems of ethnicity in a heterogeneous, multicultural state and the phenomenon of ethno-nationalism in its historical and analytical perspective in the federation of Pakistan with special reference to the status of Seraiki ethnic group. In fact ethnic expressions exist in all multicultural states and distinct ethnic groups evaluate themselves through communal prism. The less privileged groups develop abhorrence against the over – privileged groups due to the persistence of socioeconomic injustices. Factors like the gap between core and periphery, asymmetrical modernization and authoritarian trends lead towards ethnic disruption. Same is the case with Pakistan, a multilingual, multiracial and multiethnic state with federating units reflecting various diversities. The analysis of ethno-nationalism in Pakistan highlights factors, like regional cultural identity, relative deprivation among regions, centralized state structure, denial of accepting regional language as national language, and the absence of democratic values as being the root causes of the Bengali separatism. The assimilationist policies of the government do not acknowledge the regional/ethnic aspirations. Denial of pluralistic approach has been thwarting the demand for provincial autonomy. The nature of ethnic consciousness in the Seraiki belt, analyzed in this article, is found to be nurtured by the perceived socio-economic injustice at intra-provincial level—between the regions of South Punjab and Central and Northern Punjab put together

Development and Evaluation of Controlled- Release Formulations of Tramadol Hcl

For the preparation of controlled-released microparticles through non-solvent addition technique ethyl cellulose (EC) was employed. Dichloromethane (DCM) was utilized as solvent for polymer; and paraffin oil as non-solvent that induced phase separation. Microparticles of different polymer concentration M1 (1:1), M2 (1:2) and M3 (1:3) were prepared. Among all these formulations, M3 presented superior and desirable characteristics i.e. 79% entrapment efficiency, good micromeritic properties, smooth morphology and more sustained effect on cumulative release. Zero order, First order, Higuchi, Hixson-Crowell and Korsmeyer-Peppas kinetic models were applied to assess the mechanism and pattern of drug release from microparticles. Release of TmH was best fitted to Higuchi model because it presented highest values of correlation coefficient (R2=0.981) followed by zero-order kinetic model (R2=0.899). FTIR, XRD and DSC ensured the chemical stability and integrity of TmH and EC in M3; as no new bands were detected in FTIR spectra. Moreover, crystallinity of TmH was reduced in XRD, and endothermic peak was observed at the glass transition temperature of EC in DSC spectra. M3 were kept at 40°C/75% RH for three months and evaluated for stability by determining in-vitro release profile and drug assay. The effect of exaggerated environment on the stability was insignificant. The controlled-released microspheres were prepared through solvent evaporation method using ethyl cellulose as polymer. These microspheres were evaluated primarily for kinetics and stability. Microspheres of different polymer concentration M1 (1:1), M2 (1:2) and M3 (1:3) were developed and compressed into tablets i.e., T1, T2 and T3, respectively. Zero order, First order, Higuchi, Hixson-Crowell and Korsmeyer-Peppas kinetic models were applied to assess the mechanism and pattern of drug release. Higuchi model was found to be the best among all models. The chemical and physical stability of TmH formulation was studied using FTIR, Thermal analysis, X-ray diffraction and dissolution tests. In-vitro analysis showed that tablets of ratio T2 released the drug over 12hrs and the release profile was comparable with that of reference tablet, Tramal® SR. The effect of different storage temperatures on the physicochemical stability of T2 was insignificant (p > 0.05). A controlled-release combination of Tizanidine (TZD) and Tramadol (TmH) microparticles was developed and evaluated. Microparticles of both drugs were prepared separately via temperature change method. To extend the release of formulations EC polymer was employed. Higuchi, Zero order, First order, and Korsmeyer-Peppas kinetic models were applied to appraise mechanism and mode of drugs release. Higuichi model was found to be best for all release profiles. Stability of microparticles at 40oC/75%RH over three-month duration was determined by FTIR, XRD and drugs assay. Microparticles were compatible and stable as no significant differences were observed when subjected to drug assay, FTIR and XDR during accelerated stability studies. For combination of Tramadol HCl (TmH) and Acetaminophen (AAP) microparticles coacervation via temperature change method was used. Ethyl cellulose (EC) of moderate viscosity was employed to extend the release of formulations. Microparticles of both drugs were prepared separately and then compressed into bilayer tablets. Physicochemical stability of bilayer tablets was determined using FTIR, XRD, DSC and TDA. The mechanism and pattern of drugs release was assessed by the application of Higuchi, Zero order, First order and Korsmeyer-Peppas kinetic models. Higuchi model was found best for release profiles of both drugs. FTIR, XRD, DSC and TDA result findings ensured the compatibility and stability of the new formulation. Similarly, insignificant differences were observed, when subjected to accelerated stability studies. Microencapsulated TmH and AAP can be developed into bilayer tablets. This SR combination is stable and releases the drugs over 12 hours. Floating microcapsules (FMs) using combination of ethyl cellulose (EC) and hydroxy propyl methyl cellulose (HPMC) were prepared and characterized. An easy and novel phase separation method was adopted to prepare FMs. Chloroform and paraffin oil were employed as solvent and non-solvent, respectively. Five kinetic models were applied to assess and describe the mechanism and pattern of TmH release from FMs. FMs were subjected to FTIR and XRD to evaluate TmH-HPMC-EC interaction. As EC concentration was increased, retardation in the release of TmH, improvement in flow characteristics and decrease in floating time, were observed. Kinetics of drug release was followed by Korsmeyer-Peppas kinetic model. Floating microcapsules of TMH can be produced using phase separation method. Microcapsules were stable with no drug-polymer interaction. The accelerated stability studies also ensured the physicochemical integrity of FMs. Biodegradable microspheres of Tramadol Hydrochloride (TmH) were developed using simple phase separation technique. Poly lactide-co-glycolide (PLGA) was used as release controlling polymer. Simple phase separation method was adopted to prepare microspheres; Dichloromethane (DCM) and Liquid Paraffin (LP) were employed as solvent and non-solvent, respectively. Five kinetic models were applied to assess and describe the mechanism and pattern of TmH release from biodegradable microspheres. Biodegradable microspheres were subjected to FTIR, DSC and XRD to evaluate TmH-PLGA interaction. Retardation in the release of TmH was observed as PLGA concentration was increased. Kinetics of drug release followed higuchi model. The microspheres exhibited no interaction between TmH and PLGA. Biodegradable microspheres of TmH can be produced using phase separation method. Microspheres were stable with no drug-polymer interaction. The accelerated stability studies also ensured the physicochemical integrity as differences of release profile over the period of three months were insignificant. IVIVC for microparticles of tramadol hydrochloride was also established. Four formulations of controlled-release microparticles with different polymer concentration were developed and optimized in respect of encapsulation efficiency, dissolution study, release kinetics and FTIR spectroscopy. The optimized formulations were taken for in vivo studies. For in vivo analysis, a new HPLC analytical method was developed and validated. The mobile phase, comprises of phosphate buffer (50 mM), methanol and acetonitrile (75:20:05) was run at the flow rate of 0.75 mL/minutes. In vivo study was performed on twenty four healthy human volunteers and various pharmacokinetic parameters i.e., Cmax, tmax, AUC 0-∞ and MRT were calculated. The in vitro and in vivo drug data was compared to establish relationship with the help of Wagner-Nelson method. The F-4 exhibited good IVIV correlation (R2= 0.9957) compared to F-3 (R2=0.9722).
