This study was conducted with an aim to develop a novel washing-off method to remove unfixed reactive dyes from cotton fabrics with lesser amount of water and energy, without compromising color fastness properties. In this context, ozone was utilized very first time in washing-off process to ascertain color fastness properties of selected reactive dyes. After deep shade dyeing (6% owf) of C.I. Reactive Black 5, C.I. Reactive Blue 19, and C.I. Reactive Orange 7, dyed fabrics were subjected to both conventional and new washing-off methods. The new washing-off process was carried out by introducing the ozone at the bottom of bubble column reactor containing the fabric and washing-off liquor. The new process took place at room temperature using a single bath without draining or refilling with fresh water. Fabrics washed-off with both methods were compared in terms of washing fastness, crocking fastness, change of color, and magnitude of total color difference ( ∆E*cmc (2:1) ). The color fastnesses properties and final shade of the ozone treated fabrics were found to be comparable to those washed-off conventionally. Key Terms: Washing-off, Reactive dyes, AOP, Ozone, Bubble column reactor, Fastness

مولانا لقاء اﷲ عثمانی

مولانا لقاء اﷲ عثمانی
افسوس ہے کہ گزشتہ مہینہ مولانا لقاء اﷲ صاحب عثمانی نے وفات پائی، مرحوم تحریک خلافت کے دور کی یادگار تھے، ایک زمانہ میں قومی و ملی تحریکوں میں ان کا نمایاں حصہ رہا، ان کا سب سے بڑا کارنامہ یہ ہے کہ ۴۷؁ء کے خونیں ہنگامے میں جب پانی پت مسلمانوں سے خالی ہوگیا تھا، اس کی مسجدیں ویران اور خانقاہیں سونی ہوگئی تھیں، ان کے پائے ثبات میں لغزش نہ آئی اور انھوں نے اپنے جدامجد حضرت جلال الدین کبیر الاولیاءؒ کا آستانہ نہ چھوڑا، ان کے اس استقلال سے مسلمانوں کے اکھڑے ہوئے قدم دوبارہ جم گئے اور ان کی دینداری اور حسن اخلاق سے وہ شرنار تھی جو مسلمانوں کے خون کے پیاسے تھے ان کے عقیدت مند بن گئے اور آج پانی پت میں جو مسلمان نظر آتے ہیں، وہ سب ان کے استقلال اور قوت ایمانی کا نتیجہ ہے، اﷲ تعالیٰ اس مرد مجاہد کے مراتب بلند فرمائے۔ (شاہ معین الدین ندوی،جنوری ۱۹۶۹ء)

سیرت النبی ﷺ میں احتسابی عمل کی مثالیں: وفاقی محتسب پاکستان کے فرائض کا اختصاصی مطالعہ

In any society, the administration has the status of a pillar, and its good or bad move directly impacts society. There are institutions to compensate public complaints on government initiatives in many countries of the world that keep check on government administrations. For this purpose "Federal Ombudsman" was established in Pakistan. The main responsibilities of this institution include the execution to enjoin the right and forbid the wrong (Amr bil Ma’rūf wal Nahi ‘An al Munkar), monitoring government employees in administrative matters, hearing the complaints of the public against organizations and preventing them from violating individual rights. In this article, it has been reviewed that how we can seek guidance from the Sīrah of the Prophet (P.B.U.H) is in this matter, to evaluate the present system of "Federal Ombudsman". In addition, the main responsibilities of the "Federal Ombudsman" were discussed in the article. In conclusion recommendations have been made for further improvement.

Genetic Studies of Cardiovascular Diseases

Cardiovascular diseases (CVDs) are the leading cause of morbidity and mortality in the underdeveloped countries like Pakistan, leading to socioeconomic destabilization of the community. Among the different factors that play a role in the onset and progression of disease, raised plasma cholesterol levels is considered to be a major factor in the development of atherosclerosis, a typical character for the development of CVDs. Candidate gene screening of hypercholesterolemia families and sporadic individuals revealed two mutations in LDL-C binding domain (La) of LDLR (c.264G>C, p.R88S and c.887_889GCA>AGC, p.296*), four missense mutations in EGF like domain (c. 1019_1020delinsTG, p.C340L; c.1211C>T, p.T404I; c.1214 A>C, p.N405T; c.1634G>A, p.G545E and c.1916T>G, p.V639) and one premature terminating mutation (c.2416_2417 Ins G, p.V806GfsX11) in the transmembrane domain of LDLR. The La domain mutation has been shown to lead to inefficient binding of LDL-C with the receptor, while mutations in EGF like domain were found to cause decreased recycling of LDLR to the hepatocytes surface, which resulted in raised cholesterol levels in the patients. Two variants in PCSK9 i.e., c.314G>A, p.R105Q and c.464C>T, p.P155L, were also found in two different families with a history of CABG. The variant c.314G>A, p.R105Q resulted in 19% decrease in LDL-C levels in heterozygote carriers compared to homozygote normal individuals predicting it to be a “loss of function mutation”, while the second variant c.464C>T, p.P155L was located in the autocatalytic site of PCSK9 which may impact on LDL-C, but its exact effect could not be determined due to the small family size. In case control studies on MI cases in Pakistani population, the screening of selected panel of single nucleotide polymorphisms (SNPs) within five different genes was conducted. It was found that rs1333049 (ANRIL) was significantly associated with the onset of disease (p<0.001), while rs10920501 (FAM5C), rs1042579 (THBD), rs4646994 (ACE) and Intron 4 VNTR (eNOS) were not associated with the onset of MI (p>0.05). The stratification of data based on coronary artery disease (CAD) family history revealed significant association of the risk allele in ACE and eNOS polymorphisms with OR 1.83(95% CI=1.06-3.14) and 1.82(95% CI=1.03-3.22), respectively. This also indicates that the clustering of genetic factors within the ixfamilies are responsible for the onset of MI in Pakistani families. The relationship of rs1333049 risk allele “C” with phenotype impact on the lipid profile also showed a marked decrease in total cholesterol in individual homozygous for risk allele, which was observed in an independent cohort of hypercholesterolemia patients from the affected families as compared to their normolipidemic individuals. From this study, it is revealed that the Pakistani population has genetic heterogeneity, which predisposes the individuals to an increased risk of MI.
