اپنی تصویر بھی یوں مجھ سے چھپاتی کیوں ہو

اپنی تصویر بھی یوں مجھ سے چھپاتی کیوں ہو
دوسرا چہرہ بہانے سے دکھاتی کیوں ہو

تم کو معلوم ہے بنجارے کہیں ٹھہرے ہیں؟
جانے والوں کو بھلا ایسے بلاتی کیوں ہو

ایک شاعر کا یہ شکوہ ہے شکایت بھی ہے
جب دکھانی نہیں تصویر بناتی کیوں ہو

تم بھی مشتاقِ محبت ہو سبھی جانتے ہیں
جذبۂ دل کو بتائو تو چھپاتی کیوں ہو

جب ترے بس میں نہیں روگ محبت والا
تم فضاؔ دل کو یہی روگ لگاتی کیوں ہو

The Influnce E-Commerce Shopee Strategic Online Purchasing Decision Generation Z in Panam Pekanbaru

E-Commerce competition is becoming increasingly attractive in the world of online shopping, it requires a special strategy in order to compete competitively, E Commerce Shoope performs a Twin Date Event Strategy, Flash Sale, and Free Shipping Cost, Population in this study amounts to 100 people using purposive sampling methods.  Based on the results of this study, Twins Date Events, Flash Sale and Free Shipping have influenced purchasing decisions both partially and simultaneously. The results of the Determination Coefficient show that the magnitude of the influence of both free variables together on the bound variable is 54.7% and the remaining 45.3% is another variable not studied. Future research could delve into these unexplored variables to provide a more comprehensive understanding of what drives purchasing decisions in the e-commerce sector. Understanding these additional factors could further assist e-commerce platforms like Shoope in refining their marketing strategies, ensuring they not only attract but also retain customers in a highly competitive market.  

Exploration of Anthelmintic, Antidiabetic and Anticancer Potential of in Vitro Cultures of Cichorium Intybus L. , Peganum Harmala L. and Withania Somnifera L. Dun.

The present study deals with the phytochemical analyses and determination of antimicrobial, anthelmintic, antidiabetic and anticancer potential of in vitro plant tissue and callus culture extracts of Cichorium intybus L., Peganum harmala L. and Withania. somnifera (L.) Dun. Maximum seed germination was observed in P. harmala seeds. Explants such as hypocotyl and cotyledon from in vitro seedlings were cultured on MS medium supplemented with different combinations and concentrations of plant growth regulators for callus induction. The most successful culture media were 0.05 TDZ + 0.5 NAA mg/L, 0.05 TDZ + 0.5 IBA mg/L and 0.05 TDZ + 0.5 BAP mg/L for callus induction of C. intybus, P. harmala and W. somnifera two for each respectively. Four different solvents depending upon polarity were used for extraction of explant tissues and callus cultures. Maximum percentage yield was recorded in chloroform extract of cotyledon callus cultures of C. intybus followed by chloroform extract of hypocotyl callus of P. harmala and cotyledon callus of W. somnifera respectively. Phytochemical analyses of extracts indicated the presence of valuable phytochemicals such as alkaloids, flavonoids, phenols, saponins, tannins, reducing sugars and terpenoids. Antimicrobial potential was tested against pathogenic bacteria (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and fungi (Aspergillus niger and Fusarium solani). Maximum inhibition zones were recorded in methanol extracts of P. harmala and C. intybus hypocotyl callus culture against B. subtilis and E. coli respectively followed by chloroform and methanol extracts. Anthelmintic test showed that methanol extract of cotyledon callus culture of P. harmala exhibited considerable anthelmintic potential. Antidiabetic potential of methanol extracts of callus cultures was evaluated by using rabbits as experimental organisms. The extract of C. intybus hypocotyl callus culture showed maximum decrease in blood sugar level followed by the W. somnifera cotyledon callus culture in streptozotocin induced diabetic rabbits. Anticancer activity was conducted through HTC116 human colon cancer cell lines cultured in Dulbecco’s Modified Eagle Medium. Methanol extract of P. harmala hypocotyl callus cultures showed highest anticancer potential followed by chloroform extract of hypocotyl callus culture of C. intybus. It can be concluded that callus cultures of the plants selected for study hold auspicious ethno-pharmacological effectiveness and in vitro biomass production may be helpful for biodiversity conservation
