پروفیسر خواجہ حمید الدین شاہد
پروفیسر خواجہ حمید الدین شاہد نے ۲۲؍ اکتوبر ۲۰۰۱؁ء کو ۵ بجے شام کراچی میں وفات پائی، وہ اردو کے مشہور ادیب، محقق، صحافی اور شاعر تھے، پاکستان جانے سے پہلے وہ ’’ادارۂ ادبیات اردو‘‘ حیدرآباد کے تمام کاموں میں پیش پیش اور ادارے کے روح رواں ڈاکٹر سیدمحی الدین قادری کے دست راست رہے، عرصے تک ماہ نامہ ’’سب رس‘‘ کے مدیر بھی رہے۔
مرحوم نے عثمانیہ یونیورسٹی کے مختلف کالجوں میں اردو کے استاد کی حیثیت سے بھی نمایاں خدمات انجام دیں، اردو میں انہوں نے جو تصانیف یادگار چھوڑی ہیں ان میں ’’ارمغان امجد‘‘، ’’مثنوی تصویر جاناں‘‘ مصنفہ لچھمی نرائن شفیق ’’اردو میں سائنسی ادب‘‘، ’’رسالہ محمود خوش وہاں‘‘ اور ’’حیدرآباد کے شاعر‘‘ قابل ذکر ہیں۔ ۱۹۴۰؁ء میں ادارۂ ادبیات اردو کی دس سالہ سرگرمیوں کی مبسوط تاریخ ’’سرگذشت ادارہ‘‘ کے نام سے مرتب کی تھی جو وہاں سے شائع ہوچکی ہے، اس کے علاوہ رسالوں میں ادبی و تحقیقی مضامین بھی لکھتے رہے، شاعر بھی تھے لیکن کوئی مجموعہ شائع نہیں ہوا۔
پاکستان منتقل ہونے کے بعد بھی حیدرآباد اور ادارۂ ادبیات اردو ان کے دل و دماغ پر چھایا رہتا تھا۔ اپنے مکان کا نام ’’ایوان اردو‘‘ رکھا اور کراچی سے ماہنامہ ’’سب رس‘‘ جاری کیا اور اس کا ’’زور نمبر‘‘ کا اور حیدرآباد کی طرح کراچی میں بھی وہ اردو کی خدمت اور فروغ کے لیے سرگرم عمل رہے، بہادر یار جنگ اکیڈمی سے بھی تعلق تھا۔ اﷲتعالیٰ اردو زبان و ادب کے اس مخلص خادم کی مغفرت فرمائے اور ان کے اعزہ و اقربا کو صبر جمیل کی توفیق بخشے۔ (ضیاء الدین اصلاحی، جنوری ۲۰۰۲ء)

انسان کی معاشرتی زندگی پر صفات الہیہ کے اثرات

There are a lot of profound effects of attributes of Allah on the human social life. When the person recognizes the attributes of Allah, he starts efforts to adopt those attributes through which he succeeds in his practical life. In fact the knowledge of Allah’s attributes is the base of all kinds of knowledge and beleives. This paper is a study to develop the moral narms, human behavior and impact of attributes of Allah Almighty on the human society in this life and in the life hereinafter, so that it may be practiced to strengthen the moral attitudes and beleieves of the Muslim society as well as the human behavior in their life.

Synthesis and Characterization of Silver Nanoparticles Using Seed Extracts and Their Biomedical Application

Green route was employed for the fabrication of stable silver nanoparticles (Ag-NPs) using Setaria verticillata, Cenchrus ciliaris and Azadirachta indica seeds exudates as both reducing and capping agents. The physio-chemical properties of the resulting AgNPs were investigated by employing variety of characterization techniques as UV–visible spectrophotometery; X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and fourier transform infrared (FTIR) spectrometry. In this study, NPs were synthesized from silver nitrate and various concentrations of the seed extract by a green method. However, all the synthesized AgNPs showed quasi spherical morphology under transmission electron microscope (TEM).SV Ag-NPs are prepared by using S. Verticillata seeds exudates, their in-vitro toxicity was studied on adult earth worms (Lumbricina) resulting in statistically significant (P < 0.05) inhibition, in addition; 3-(4, 5 dimethylthiazol-2-yl) 2, 5diphenyltetrazolium bromide (MTT) assay with Baby hamster kidney cells (BHK-21), revealing dose dependent cytotoxic effect of -NPs.The anti-microbial activities of the 0.75µg/ml Ag-NPs were tested against various gram-positive (Bacillus anthracis, Bacillus amyloliquefaciens, Staphylococcus aureus and Staphylococcus warneri) and gram-negative (Escherichia coli and Acinetobacter baumannii) bacteria, demonstrating efficient inhibition of pathogen growth. The sample 40SV were loaded with hydrophilic anticancer drugs (ACD) doxorubicin (DOX) and daunorubicin (DNR) for developing novel drug delivery carrier having significant adsorption capacity and efficiency in order to expurgate the side effects of the medicine, effective for leukemia chemotherapy. A. indica Ag-NPs were rapidly synthesized using an aqueous seed extract with AgNO3 solution within 30 minutes and their size ranged between 10 – 30 nm. However, the synthesized NPs showed spherical morphology with an average diameter of 13 nm when observed under transmission electron microscope (TEM). A. indica Ag-NPs showed enhanced bactericidal action against gram-positive (Bacillus anthracis, Bacillus amyloliquefaciens, Staphylococcus aureus and Staphylococcus warneri) and Gramnegative (Escherichia coli and Acinetobacter baumannii) strains compared to raw A. xi indica seed extract. However, Ag-NPs interacted with the bacterial membrane, caused cellular leakage and ultimately cell death as evident from TEM images. Moreover, AgNPs reduced congo red (CR) and methylene blue (MB) that suggests their catalytic potential in the removal of industrial organic dyes.C. ciliaris Ag-NPs are prepared by using Cenchrus ciliaris seeds exudates. Increasing C. ciliaris concentration leads to a reduction in the particle size and the agglomeration between the NPs. The results showed that synthesized Ag-NPs (1-3CC) are less agglomerated and exhibited significant antimicrobial potential against various bacterial strains compared to 4-5CC This report highlights the effect of nanocatalyst on the degradation rate of toxic contaminants, methylene blue (MB) and congo red (CR) by NaBH4 in an eco-friendly manner. In addition, Ag-NPs were loaded with anticancer drugs (ACD) [doxorubicin (Dox) hydrochloride, and daunorubicin (Dono)] to develop novel drug carrier with high loading capacity and rapid drug adsorption rate to hampered the side effects of ACD. The loading capacity of ACD was investigated as a function of contact time and adsorption dosages had a maximum adsorption capacity of 404.19 and 253.85 mg/g for Dox and Dono respectively. Moreover, kinetic models were conducted to evaluate the adsorption kineticsThe anti-microbial activities of the Ag-NPs were tested against various bacterial strains, thick wall of peptidoglycan (PG) in Gram positive strains made them less vulnerable to Ag-NPs penetration. Cell wall of Gram negative strains facilitate the entry of NPs makes difference in the bactericidal activity of Ag-NPs. However, Ag-NPs interacted with the bacterial membrane, caused cellular leakage and ultimately cell death as evident from TEM images.This work also highlights the effect of nano catalyst on the degradation rate of toxic contaminants, methylene blue (MB) and congo red (CR) by NaBH4 in an ecofriendly manner. Moreover, Ag-NPs reduced CR and MB that suggests their catalytic potential in the removal of industrial organic dyes. The current findings will provide an insight for the preparation of green bactericidal, anticancer, anthelmintic and catalytic agents that can be used in biomedical applications.
