Grammar Translation Method In ELT: Hindering The Development Of Communicative Skills At Secondary Level
The purpose of this study is to evaluate the communication skill of students in English who were taught by Grammar Translation Method (GTM) at secondary school level in Pakistan. There is not usually any listening or speaking practice in GTM. Very little attention is placed on pronunciation or any communicative aspect of language. The skill exercised is reading and then only in the context of translation. Examinations also consist of translation of classical text. A questionnaire was used to collect data from15 teachers of Govt. schools of district Faisalabad who were using this method in the schools. The quantitative data were analyzed by simple frequency count and percentage, and qualitative data through the description of the classroom observation and interview. Analysis of the data shows that GTM put more emphasis on learning English words, phrases, sentences and structure pattern; but it has failed in practical use of English in real life situation. Students learning through this method at secondary school certificate level Pakistan in are unable to communicate even a basic conversation in English. It is suggested that the teachers should adopt communicative approach in ELT so that the communicative ability of the students may be enhanced.

Effectiveness of Natural Antioxidants against SARS-CoV-2? Insights from the In-Silico World
The SARS CoV-2 pandemic has affected millions of people around the globe. Despite many efforts to find some effective medicines against SARS CoV-2, no established therapeutics are available yet. The use of phytochemicals as antiviral agents provides hope against the proliferation of SARS-CoV-2. Several natural compounds were analyzed by virtual screening against six SARS CoV-2 protein targets using molecular docking simulations in the present study. More than a hundred plant-derived secondary metabolites have been docked, including alkaloids, flavonoids, coumarins, and steroids. SARS CoV-2 protein targets include Main protease (M(Pro)), Papain-like protease (PL(pro)), RNA-dependent RNA polymerase (RdRp), Spike glycoprotein (S), Helicase (Nsp13), and E-Channel protein. Phytochemicals were evaluated by molecular docking, and MD simulations were performed using the YASARA structure using a modified genetic algorithm and AMBER03 force field. Binding energies and dissociation constants allowed the identification of potentially active compounds. Ligand-protein interactions provide an insight into the mechanism and potential of identified compounds. Glycyrrhizin and its metabolite 18-β-glycyrrhetinic acid have shown a strong binding affinity for M(Pro), helicase, RdRp, spike, and E-channel proteins, while a flavonoid Baicalin also strongly binds against PL(pro) and RdRp. The use of identified phytochemicals may help to speed up the drug development and provide natural protection against SARS-CoV-2
Association between TSH status and prevalence of miscarriages and stillbirth
Thyroid hormones play a significant role in normal human body growth. Abnormalities in thyroid stimulating hormone (TSH) levels can result in pregnancy loss due to miscarriages and intrauterine death (IUD). The objective of the study was to assess the levels of association of thyroid stimulating hormone with miscarriages and IUD. The descriptive study involving 110 samples between 18-40 years of age fulfilling inclusion criteria were sampled for TSH testing (2ml blood) after attaining their written informed consent. The mean age of participants was 29.49±4.26 year. The prevalence of hypothyroidism and hyperthyroidism was 3.64% and 2.73%, respectively. Complications like gestational hypertension, depression and oligomenorrhea were found prevalent in these females. Majority of females were taking high/low iodine than recommended iodine level (150mcg). This work shows that there is a significant association between pregnancy loss and disturbed TSH levels among pregnant females
Process optimization for enhanced production of cellulases form locally isolated fungal strain by submerged fermentation
Cellulase has myriad applications in various sectors like pharmaceuticals, textile, detergents, animal feed and bioethanol production, etc. The current study focuses on the isolation, screening and optimization of fungal strain through one factor at a time technique for enhanced cellulase production. In current study sixteen different fungal cultures were isolated and the culture which quantitatively exhibits higher titers of cellulase activity was identified both morphologically and molecularly by 18S rDNA and designated as Aspergillus niger ABT11.

Objective: To build up the nutritional status of the neurosurgical patients with an easy and practical way. Patients and Methods: This prospective study was conducted in Neurosurgery department of Pakistan Institute of Medical Sciences Islamabad in a six months’ time. In total thirty adult patients of either gender with H/O road traffic accident with severe head injury and GCS less than 8/15, persistent vegetative state, brain tumor patients who had developed lower cranial nerve palsies were included in the study. 28 for two way Foleys catheter was used in feeding gastrostomy. Results: Thirty patients, with the median age of 35 years (range, 18-55 years) underwent feeding gastrostomy. Before the gastrostomy tube insertion, 18 patients had enteral nutrition by a nasogastric tube and 10 had parenteral nutrition (PN), with a median duration of 14.5 (range, 4-60) and 12 (range, 7-25) days, respectively. Two patients accidentally pulled out the gastrostomy tubes 10 and 11 days after insertion. Buried bumper syndrome developed in 1 patient. Two patients died 8 and 34 days after the procedure in the neurosurgical ICU. Twenty-eight patients were discharged from the hospital while being fed via the gastrostomy tubes. In 11 patients who were able to resume oral feeding, the tube was removed, with a median interval of 62 (range, 25-150) days. There was no Procedure-related mortality. Conclusion: An improvised method of nutritional support according to our circumstances. This study can be extended to other surgical and medical patients who need nutritional support for longer period of time. 
Bioethanol production from urban cellulosic waste employing Alcaligenes faecalis HI-1 isolated from gut of termite Heterotermes indicola
This study assessed the potential of termite gut inhabiting bacteria towards bioconversion of cellulosic waste into biofuel. Total seven bacterial isolates from the gut of Heterotermes indicola were isolated. Among all the isolates, HI-1 produced the largest zone upon primary screening. Untreated paper had more cellulose content (73.03%) than acid (0.5%) treated paper that was used as a lignocellulosic substrate for saccharification. Among all the isolates tested, glucose yield (1.08mg/mL) was high for HI-1 isolate. Several factors were considered for optimizing augmented glucose yield (8.57mg/mL) and growth (8.07×108cfu/mL), such as temperature 37°C, pH 4.5, 5% (w/v) substrate concentration, 6 % bacterial inoculum size, agitation 150 rpm with PEG 0.25 % and Ca2+ ions 0.002 g/L. Overall 8-fold increase in glucose yield was achieved. Enzyme activity of HI-1 showed higher endoglucanase 0.29 ± 0.01 (U/mL/min) and exoglucanase 0.15±0.01 (U/mL/min) activity under optimum conditions, mentioned above. temperature 37°C, pH 4.5, substrate concentration 5%, inoculum size 6%, surfactants PEG 0.01%, ions Ca2+(0.002g/L) and agitation (120 rpm). Simultaneous saccharification and fermentation (SSF) of hydrolyzed office paper yielded 5.43mg/mL bioethanol. According to 16S rRNA sequence homology, the bacterial isolate H1 was identified as Alcaligenes faecalis. Bioethanol production from office paper untreated waste proved an effective strategy. Bacteria having natural tendency towards cellulosic waste consumption are promising for bioconversion of cellulosic waste to valuable products
