خلاصہ بحث

ایمان اسلام کو جزو لاینفک ہے اس کے بغیر اسلام قابل قبول نہیں کوئی بھی شخص مکمل ایمان لائے بغیر دائرہ اسلام میں داخل نہیں ہو سکتا ۔ فصل اول میں ایمانیات کے بارے میں قرآن مجید کی درج ذیل سورتوں کی ۲۰ آیات سے وضاحت کی گئی ہے۔

سورة آل عمران آیت نمبر ۱۶۰، سورة النساء آیت نمبر۸۲، سورة الاعراف آیت نمبر۱۸۵، سورة يونس آیت نمبر۳۴، سورة بنى اسرائیل آیت نمبر ۹۹، سورة الانبياء آیت نمبر ۴۲، سورة الحج آیت نمبر۷۰، سورة المؤمنون آیت نمبر ۸۵،۸۶،۸۷،۸۸،۸۹، سورة النور آیت نمبر ۵۰، سورة الروم آیت نمبر ۳۵،۳۷ ،سورةالزمر آیت نمبر ۴۳، سورة المؤمن آیت نمبر ۸۱،۸۲، سورة المرسلات آیت نمبر۲۰،۲۵، اس فصل میں ان آیات میں اللہ تبارک وتعالیٰ نے اپنے بندوں سے سوال فرمایا ہے۔

اس فصل میں ہر آیت کو بیان کرنے کے بعد اس کی تفسیر پر روشنی ڈالی گئی ہے اور اس آیت میں استفہام کے استعمال کی وضاحت کی گئی ہے کہ ہر آیت میں اللہ تبارک و تعالیٰ کا سوال کرنے کے پیشِ نظر جو مقصد کارفرما تھا اس کو واضح کیا گیا ہے۔

تحریک قیام پاکستان: سید ابو الاعلی مودودی اور مولانا اشرف علی تھانوی کی فکری مماثلت

Syed Abul Ala Moudoodi and Maulana Ashraf Ali Thanwi were the genii of their time. They influenced political and religious trends of their time. They observed the period of Pakistan movement and struggle for freedom. Though Maulana Ashraf Ali Thanwi had passed away in 1943 whereas Syed Moudoodi died later in 1979. They belong to a different school of thought but they were coincident in their views about Pakistan movement. Syed Moudoodi having different political theology had a distinct political agenda. Because Syed Moudoodi was abandoned from Mysticism intentionally and started his political movement on his intellectual and theological thinking. On the other side Maulana Ashraf Ali Thanwi owing Mystic ideology; abandon from livelihood; though having deep insight in political affairs. This is very authentic that both having the same intellectual ideology; were against Congress and consider her like a poisonous killer. They had envisioned and desire to optimise the weaknesses of the Muslim League.

Niosomal Encapsulation of Anticancer Drugs and Assessment of Their Activity Through Cancer Cell Line

Niosomes are self-organizing non-ionic surfactant vesicles, which encapsulate aqueous volume of drug(s) with or without the addition of cholesterol and other lipid contents. Niosomes have the capability to encapsulate both lipophilic and hydrophilic drugs. They are alternative to liposomes, and their main benefits as compared to liposomes are their lower price, higher stability and better biodegradability. By making niosomes, the side effects of drugs have been reduced and the therapeutic efficacy has been increased. The first part of the study was to develop an optimized niosome formulation for the encapsulation of a poorly water-soluble drug by the ecological probe sonication method. Pluronic L121 and Span 60 were used as surface active agents and the optimization of the composition was made with the aid of Design of Experiment (DoE) concept. Rifampicin was used as a model drug. Concentration levels of charge inducing agent, dicetylphosphate (DCP), and Pluronic L121 were studied as variables. Prepared niosomes with varying concentrations of DCP and Pluronic L121 resulted in small sized niosomes with sizes ranging from 190 nm to 893 nm. During the four weeks stability testing, the particle sizes were reduced slightly. The formulation containing 2 mg of DCP resulted in most stable niosomes with 75.37% entrapment efficiency. All the niosomal formulations showed higher In vitro drug release rates as compared to bulk drug formulation. The rifampicin loaded niosomes prepared with Pluronic L121 and Span 60 resulted in stable, small sized niosomes with improved drug release profile. The second part of the study was carried out to produce niosome formulations for the encapsulation of a hydrophilic and poorly water-soluble drugs by the ecological probe sonication method. Pluronic L121 and Span 60 were used as surface active agents and the optimization of the composition was made with the aid of Design of Experiment (DoE) concept. Ceftriaxone sodium and Rifampicin were used as model drugs (hydrophilic and hydrophobic respectively). Concentration levels of charge inducing agent, dicetylphosphate (DCP), and Pluronic L121 were studied as variables. Prepared niosomes with varying concentrations of DCP and Pluronic L121 resulted in small sized niosomes with sizes ranging from 164 nm to 893 nm. During the four weeks stability testing, the particle sizes were reduced slightly. The formulations CR1 and CR2 resulted in most stable niosomes with (98.71% of rifampicin and 95.73% ceftriaxone) and (98.86% rifampicin and 95.88% ceftriaxone) entrapment efficiency of respective formulations. All the niosomal formulations showed higher In vitro drug release rates as compared to bulk drug formulations. The ceftriaxone and rifampicin loaded niosomes prepared with Pluronic L121 and Span 60 resulted in stable, small sized niosomes with improved drug release profile. In the third part of study, the niosome formulations were prepared for the encapsulation of anticancer drugs by the ecological probe sonication method. Pluronic L121 and Span 60 were used as surface active agents in niosomes and doxorubicin HCl and paclitaxel were used as anticancer drugs. Thorough physicochemical studies were performed for the niosomes and their cytotoxicity and activity were evaluated on MCF-7 and PC3- MM2 cancerous cell lines. Prepared niosomes were small with sizes ranging from 137 nm to 893 nm and entrapment efficiencies were high, ranging from 91.24% to 99.99%. During the four weeks stability testing, the particle sizes remained stable. The niosomal formulations showed In vitro sustained drug release profiles for doxorubicin HCL and increased clearly dissolution rate of poorly water-soluble paclitaxel. The incorporation of both the drugs into niosomes, improved cell penetration and antiproliferative activity of the drugs towards PC3 as compared to MCF-7 cell lines. As a conclusion, doxorubicin HCl and paclitaxel loaded niosome formulations resulted in relatively stable, small sized niosomes with improved drug release profiles, better cell penetration and antiproliferative activity. The niosomes showed more antiproliferative effect due to the presence of both drugs, which can overcome multidrug resistance. The present study suggested that the codelivery of anticancer drugs can be delivered by encapsulating in niosomes prepared from Pluronic L121 and Span 60. Through which improved in-vitro sustained release of both anticancer drugs, better cell penetration and antiproliferative activity. The further in-vivo evaluation can lead to treat different types of cancers in a better way without toxic effects with reduction in doses.
