Milk is generally considered as highly nutritious and useful food for all age groups as well as inexpensive and widely available. However, its quality and microbial content are the features which have to be observed. The quality of milk depends on its biochemical composition and hygienic conditions during the collection of milk and its distribution. Milk itself acts as best medium for enhancing the growth and development of different types of microbes because of its composition and presence of water in large quantity. Milk sold in Muzaffargarh district was suspected to be contaminated because of repeated outbreaks of gastroenteritis. In this context, the research was designed to rule out molecular detection and quantitative analysis of Escherichia coli (E. coli) in the milk samples obtained from various tehsils of Muzaffargarh district. E. coli were considered as the most prevalent bacteria of milk and could be the most probable microbe causing this disease. In this research, 100 raw milk samples were gathered in a way that 10 samples each were collected from Jutoi, Alipur, Kotadu, Murad Abad, Choak Qureshi, Ahmadpur, Rohilan Wali, Shahjamal, Khanpur and Muzaffargarh city. Then the samples of milk were cultured on different culture media for bacterial segregation. Identification of bacterial specie was done through gram?s staining and properties of bacterial culture on different selective media. Biochemical tests were also performed which include catalase and coagulase tests. Final identification was performed through PCR and resolution of PCR products by gel electrophoresis. Antibiotic sensitivity test was also performed so as to confirm the susceptibility of E. coli regarding multiple antibiotics. Out of 10 samples collected each from Jutoi, Alipur, Kotadu, Murad Abad, Choak Qureshi, Ahmadpur, Rohilan Wali, Shahjamal, Khanpur and Muzaffargarh city, results had shown the presence of E.coli in 4(40%), 6(60%), 3(30%), 2(20%), 4(40%), 5(50%), 3(30%), 4(40%), 6(60%) and 5(50%) samples respectively. E. coli isolates were amplified by PCR based on 16S rRNA gene. Results of antibiotic sensitivity test revealed that E. coli isolates had shown resistance to amoxicillin (85%) and erythromycin (72%). However, they were found to be affected by azithromycin (53%), ciprofloxacin (86%), gentamicin (86%), norfloxacin (80%) and streptomycin (66%). Resistant pattern in relation to broad spectrum antibiotic (i.e., amoxycillin) points to a situation which should be considered carefully and suggests that indiscriminate use of antibiotics for precautionary or therapeutic purposes should be avoided as it could be the cause of increasing antimicrobial resistance.
ڈاکٹر محمد ضیاء الدین انصاری ڈاکٹر محمد ضیاء الدین انصاری میرے مخلص اور عزیز دوست تھے، مجھے ان کے انتقال کی خبر بہت دیر سے ملی، وہ علی گڑھ مولانا آزاد لائبریری میں ڈپٹی لائبریرین تھے، وہاں جاتا تو مطلوبہ کتابیں فوراً حاضر کرتے اور چائے سے خاطر تواضع کرتے، اصرار کرکے گھر بلاتے اور پرتکلف دعوت کرتے، خدابخش لائبریری کے ڈائریکٹر ہوکر وہ پٹنہ گئے تو اسے ترقی دینے کے لئے متعدد کام کئے اور کئی سمینار کرائے جن میں مجھے مدعو کرتے، وہاں سے ریٹائر ہوکر علی گڑھ آئے تو مولانا حسین احمد مدنیؒ پر ایک سمینار کا پروگرام بنایا مگر وہ نہ ہوسکا، ضیاء الدین صاحب کو علم و ادب سے بڑا شغف تھا اور وہ اچھے منتظم بھی تھے، کئی کتابیں لکھیں لیکن اشاریہ نگار کی حیثیت سے انہوں نے اپنا خاص سکہ جمایا، وہ بڑے شریف، نیک طینت، خوش خلق اور مرنجان مرنج شخص تھے، اﷲ تعالیٰ انہیں جنت نعیم عطا کرے اور پس ماندگان کو صبر جمیل عطا فرمائے، آمین۔ (ضیاء الدین اصلاحی، اپریل ۲۰۰۷ء)
In the context of blasphemy issue, the present study examines the socio-cultural elements in the Moral Ethics syllabi functional at the different universities of Pakistan. As per our hypothesis, ME syllabi lack some important socio-cultural elements responsible for handling hate crimes, especially the issue of blasphemy. For testing the proposed hypothesis, available ME syllabi were collected from the official websites of different universities. Collected ME syllabi were examined through the method of content analysis. After examining literature review, necessary socio-cultural factors (SCFs) were listed and the selected syllabi were evaluated through this list of SCFs. Our study findings endorse the primary hypothesis that majority of universities has adopted the foreign model of ME syllabi without adapting them according to indigenous social and cultural needs. Additionally, the most important SCFs; knowledge of blasphemy laws (KBL) and real-life dilemmas (RLD), are mostly absent in the existing ME syllabi.
The presented research work in this dissertation comprises of synthesis, characterization, antimicrobial, hemolytic and enzyme inhibition studies of some new acetamides/sulfides bearing substituted-1,3,4-Oxadiazole and morpholine moieties. The acetamide, 1,3,4-oxadiazole and morpholine moieties are important functionalities because of their broad range of known pharmacological activities. Synthetic approaches (scheme-1-11) were utilized to synthesize poly-functional compounds. In first scheme, twenty three 5-substituted-1,3,4-Oxadiazol-2-thiols were synthesized by converting multifarious organic acids consecutively into the corresponding esters and hydrazides. Further the intermolecular cyclization of various carbohydrazides with carbon disulfide and potassium hydroxide yielded subsequent 5- substituted-1,3,4-Oxadiazol-2-thiols. Moreover, the reaction of different 5- substituted-1,3,4-Oxadiazol-2-thiols (scheme-2 & 3) with electrophiles, 2-bromo-N- [4-(4-morpholinyl)phenyl]acetamide and 2-bromo-N-[2-(4-morpholinyl)phenyl] acetamide yielded thirteen, N-[4-(4-morpholinyl)phenyl]-2-[(5-aryl/aralkyl-1,3,4- Oxadiazol-2-yl)thio]acetamides and fourteen N-[2-(4-morpholinyl)phenyl]-2-[(5- aryl/aralkyl-1,3,4-oxadiazol-2-yl)thio]acetamides respectively in the presence of N,N- dimethylformamide and sodium hydride. Sixteen novel benzyl sulfides (scheme-4) bearing 1,3,4-oxadiazole moiety and sulfo- morpholine functionality were synthesized (bromomethyl)phenyl)sulfonyl)morpholine with by the different reaction of 4-(4- 5-substituted-1,3,4- Oxadiazole-2-thiols. Nucleophilic substitution reaction of free thiol group in 1,3,4- Oxadiazoles with 4-(2-chloroethyl)morpholine hydrochloride yielded thirteen, 4-[2- [[5-aryl/aralkyl-1,3,4-Oxadiazol-2-yl]thio]ethyl]morpholine derivatives (scheme-5) in the presence of acetone and potassium carbonate . A series of nineteen electrophiles (scheme-5), N-substituted-2-bromoacetamides was developed by the reaction of different substituted/unsubstituted aryl/aralkyl/alkyl amines with 2-bromoacetyl bromide by using DCM or basic aqueous medium as solvent. Seventy one (71) acetamides were synthesized by the reaction of 5-(2-chloro/3- chloro/4-chloro/4-nitrophenyl/phenyl)-1,3,4-Oxadiazol-2-thiols with different electrophiles by simple stirring in the presence of DMF solvent and NaH base at the room temperature. The structures of all the synthesized compounds were characterized by using IR, 1H- NMR and mass spectral data. In addition, 13C-NMR technique was also used in some cases to support the structural analysis. A rational mass fragmentation pattern of some of the compounds is also proposed. Some of the 1H-NMR, 13 C-NMR and EIMS spectra of synthesized compounds are also presented for the obvious perceptive of signals. The synthesized compounds were evaluated for antibacterial, antifungal, hemolytic and enzyme inhibition activities. Some of compounds were found to be active and showed interesting results in different studies declared above. The biological activity data in comparison of each scheme with the reference standard drugs is presented in biological activity section.
