In current century, plant-derived polymers have attracted considerable attention because of their various pharmaceutical applications such as diluents, binders, disintegrants in tablets and particularly for sustained drug release system. In present study, efforts was subjected to purify, hydrolyze, modify and biosynthesis of nanoformulations using Cordia myxa gum to document its binder potential in pharmaceutical tablets formulation and anticancer effect. The hydrolysis, modification and biosynthesis of nanoparticles was carried out to remove impurities, roughness, increase thermal stability and to improve the functional properties of biopolymers. Silver nitrate and purified gum C. myxa as reducing agent was used to prepare nanoparticles. All the gum samples (crude, purified, hydrolyzed, modified and biosynthesized nanoparticles) were examined to assess their antioxidant and antimicrobial potential. Toxicity, non-mutagenic activity and blood haemolysis was also examined. Characterization of all the forms of C. myxa was carried out using advance techniques like UV/Visible spectroscopy, dynamic light scattering (DLS) or zeta sizer, scanning electron microscopy (SEM), X-ray diffraction (XRD), Energy dispersive X-ray (EDX), Fourier transform infrared (FTIR), Thermogravemetric analysis (TGA) and Differential scanning calorimetry (DSC). The binder potential of Cordia myxa gum and all modified forms were studied in paracetamol tablets and was compared with standard hydroxypropyl methylcellulose (HPMC) being used as synthetic binder. Pure gum and biosynthesized nanoparticles were examined for cytotoxicity (MTT assay) in order to assess their anticancer effect. A549 lung cancer and MCF-7 breast cancer cell lines were treated with samples. Synthesized spherical nanoparticles were up to 55 nm in size. The UV/visible spectroscopic results revealed an intense peak at 428nm. The highest phenolic contents and % scavenging activity were represented by purified gum (14.71 ± 0.04 mg) and (86.54 ± 0.72) whereas bactericidal activity against Escherichia coli was found maximum in nanoformulation while minimal effect against Staphylococcus aureus and the inhibition zone was calculated up to 42 and 14 mm, respectively. Nano formulated samples also exhibited optimal fungicidal effects against (F. solani & A. niger) and inhibited zones were up to 11.09 and 15.53mm. The consequences of the results portrayed that modifications might be beneficial to food products as an additive. The crude and purified gums with slower release can be used as sustained drug system or release controlling polymer. Pure gum and nanoparticles impart considerable anticancer effect and about 55-60% cell death was observed in MTT assay. Even DNA damage activity was assessed using single cell gel electrophoresis or comet assay that also proved its non-fatality. The current research work explored the cordia myxa for its applications as natural bio-binder, sustained drug delivery system and in cancer therapeutics.

(آنحضور قبلہ صوفی محمد اصغر صاحب رینجرز والے آف جہلم شریف والوں کے جانے کے بعد یہ نظم تحریر میں آئی)
ٹُر گئے کر کے مندڑا حال
وسدے ہاسے سجناں نال
سجناں باہجھوں دل کرلاندا
رو رو ہاڑے ترلے پاندا
ماہی جلدی مکھ وکھال
ٹُر گئے کر کے مندڑا حال

ماہی ساڈا سب توں سوہنا
لے گیا ہاسے، دے گیا رونا
رو رو غم تھیں ہوئے نڈھال
ٹُر گئے کر کے مندڑا حال

دلبر سانوں چھوڑ سدھارے
جوں رانجھا گیا تخت ہزارے
روندی رہ گئی ہیر سیال
ٹُر گئے کر کے مندڑا حال

سجن سانوں کملی کیتا
ٹر گیا چھڈ کے چپ چپیتا
رو رو کھلے سر دے وال
ٹُر گئے کر کے مندڑا حال

قادری سائیںؔ دے نال جے ویندے
کدی ناں اتنے دُکھڑے پیندے
مکدے فیر سارے جنجال
ٹُر گئے کر کے مندڑا حال

السلم و السلام و تطبيقا تھا في ضوء السيرة النبوية

There is no doubt that Islam is a religion of peace which ensures peace regionally and globally in the light of its teachings. It is not only a religion of worship, but it is a religion includes ethics and caring for others and takes care of the rights of individuals as well as society. The life of Prophet Muhammad, r is the best role model in creating world peace atmosphere as He had ordered his followers and believers to realize peace in their societies. Islam guarantees peace even in war situation as it provides full protection and refuge to all those innocents who do not participate in the war. It is not unknown now that the contemporary world is witnessing events that souls hate and hearts alienate which caused racisms and populism and that their effects threatened communities and destroy firm foundations of peace. So in this contemporary perspective, the importance of research and writing about world peace increases subject to all of the studies levels, whether in universities or conferences especially in light of the biography of Holy Prophet Muhammad r. In this research, I will focus on the following points: Peace and its practical examples in of Holy Prophet Muhammad r. Explanation about the concept of peace and its practice in life of Holy Prophet Muhammad r. Clarifying the most prominent contemporary security challenges in the light of the Prophet's biography. Discussion on common misconceptions about Global peace matter and their correction in the sacred Biography of the Prophet Muhammad r

Pharmacological and Toxicological Screening of Vernonia Anthelmintica

Importance of herbal medicine cannot be denied even in the modern era. Various active allopathic medicine came into being from plant origin. Vernonia anthelmintica is one such herbal remedy that has been used in traditional system of medicine. Many parts of this plant are being used by humans for curing various illnesses. Since the use of seeds of Vernonia anthelmintica is increasing in traditional practice it is the need of time to establish its safety and efficacy by thorough screening in terms of toxicity as well as pharmacological activity. Though few studies authenticate some pharmacological actions of this herb however, the safety profile is lacking even in these studies. Present study is thus designed to evaluate the toxicological and pharmacological potential through in-vitro and in-vivo methods. In vitro experiments include phytochemistry of hexane, ethanol extract and water decoction of Vernonia anthelmintica seeds. Moreover bio-assays to evaluate antibacterial, cytotoxic, antioxidant, antiglycation, phytotoxic, insecticidal and antileishmanial potential of hexane and ethanol extracts were also undertaken. In-vivo methods include subchronic toxicity studies conducted on rabbits to elucidate its effects on hematology, coagulation, hepatic function, renal profile, electrolyte status and metabolism of lipids and glucose. Pharmacological disease models were also designed in Sprague drawly rat and albino mice to establish its role in hyperlipidemia, diabetes, inflammation and nociception. The results revealed cytotoxic potential against selected cancer cell line, strong dose dependent antioxidant and phytotoxic potential and moderate antileishmanial potential in selected extracts. Considerable antiglycation potential was also observed in ethanol extract. Present study also revealed the safety of Vernonia anthelmintica on subchronic use. In vivo results showed no deleterious alteration in hematology, renal function, liver function and lipid/ glucose metabolism as compared to normal control. Subchronic use of Vernonia anthelmintica showed favorable coagulation profile by lowering fibrinogen levels. Furthermore Vernonia anthelmintica showed favorable effects in disease model of hyperlipidemia, diabetes, inflammation and nociception. Subchronic dosing also showed weight reducing potential of Vernonia anthelmintica. Present results thus suggest the possible role of Vernonia anthelmintica in the safe treatment of obesity, diabetes, hyperlipidemia, inflammation, nociception, cancer and leishmaniasis. Furthermore its strong antioxidant potential can be used in preparing remedies to combat various diseases attributable to oxidative stress.
