قصیدہ سب سے بہتر ہے ہاشکوں کو زباں کر لوں


قصیدہ سب سے بہتر ہے کہ اشکوں کو زباں کر لوں
یہ کلمہ سب سے بہتر ہے کہ اشکوں کو زباں کر لوں

کہاں تسبیح کا دانہ ؛ کہاں قسمت ہے آنسو کی
وظیفہ سب سے بہتر ہے کہ اشکوں کو زباں کر لوں

ادب گاہِ نبوّت میں زباں بندی کا عالم ہے
تقاضا سب سے بہتر ہے کہ اشکوں کو زباں کر لوں

نہیں منت کشِ تابِ صبا احوالِ دل اپنا
ذریعہ سب سے بہتر ہے کہ اشکوں کو زباں کر لوں

جہانِ کیفیت میں چشمِ تر کا مرتبہ اعلیٰ
قرینہ سب سے بہتر ہے کہ اشکوں کو زباں کر لوں

کبھی جب طعنہ زن ہوں نامۂ اعمال پر عصیاں
مداوا سب سے بہتر ہے کہ اشکوں کو زباں کر لوں

اگر وہؐ پوچھ لیں عرفانؔ! مجھ سے حالِ دل میرا
’’طریقہ سب سے بہتر ہے کہ اشکوں کو زباں کر لوں‘‘

Exploring the Prevalence of Long-Covid and its Factors among Post-Covid Survivors of Karachi

Long COVID or post-COVID problems are long-term effects of COVID-19 infection that certain people who have contracted the virus can experience. This may result in having persistent symptoms for 3 months or more, such as those who had tiredness, malaise, changed smell and taste, dyspnea, and cognitive deficits three or more months after their initial COVID-19 diagnosis. However, some people may still have inferior work performance and a lower quality of life due to the long COVID episodes. From October 2021 to April 2022, cross-sectional research was conducted in Karachi, utilizing an electronic questionnaire to record sociodemographic data, current comorbidities, and previous episodes of acute COVID-19, post-COVID symptoms, and job performance among COVID survivors. The study's findings revealed that more than 35% of individuals surveyed claimed to have had COVID symptoms for six weeks or more, with approximately 20% to 30% of those reporting frequent coughing and appetite loss. Planning prevention, rehabilitation, and clinical treatment need an awareness of long-term COVID and its related components in order to maximize recovery and long-term COVID-19 outcomes.   DOI: https: //doi.

Purification, Characterization and Binding of Metals to Zinc Alpha 2-Glycoprotein Zag by Employing Various Techniques

In this thesis ―Purification, Characterization and Binding of Metals to Zinc Alpha 2-Glycoprotein (ZAG) by Employing Various Techniques‖ the development of several techniques were carried out to analyze the interaction of biologically important metals of Irving William Series. The expression and purification of the ZAG protein was also optimized for the preparation of samples. The folding to the native conformation was also carried out. That ZAG protein is present in almost all fluids of the body. Since the discovery of ZAG, several studies have been carried out. The importance of ZAG as an important biochemical agent is known long before. The growing number of literature since today demonstrates that it’s an important biomarker for the cancer cachexia, prostate cancer, lipid mobilizing agent and obesity suppressor. The crystal structure of ZAG reveals that the fold and distribution of domains are similar to the Major histocompatibility complex-I (MHC-I) molecules. This class is known for their immune regulation and thus ZAG is believed as a central player in the immune system and cellular signaling. There is no clear evidence of ZAG participation in the cancerous conditions but over expression is dealt as a biomarker. The study shows that the ZAG interacts with several ligands. There interaction with metals is known for boosting the bioactivity of ZAG. Although, it’s believed long ago that the ZAG is an important protein that participate in several biochemical processes and little is known to understand the ligands bound conformations of ZAG with their targets like peptides and metals. In this current project, we were focused to get the good expression and purification procedure for the preparation of ZAG. The unnative aggregated fold of ZAG from the inclusion bodies was transformed into the native fold using refolding and dialysis method optimization. The introduction of histidine tag to the C-terminal and their successful removal by the Carboxypeptidase Y enzyme was also carried out. The results of the cleavage of histidine tag were evaluated with gel electrophoresis, Mass Spectrometry and Fluorescence Spectroscopy. The confirmation of native fold and bioactivity was also confirmed from DAUDA binding affinity using fluorescence emission. The formation of metal complex of Irving William Series with ZAG and their respective complexation analysis was also studies using MALDI-TOF MS and Fluorescence Spectroscopy. xiii It was found that the ZAG has multiple binding sites that interact with metals even in the presence of DAUDA. The X-ray tube analysis using FPXRF shows that Fe (III) and Co (II) has similar concentration of atoms bound to ZAG molecules.
