Clinical Comparison of COVID Waves 2-5. An Inpatient Retrospective Comparative Analysis From Karachi, Pakistan.

Background: Each coronavirus disease 2019 (COVID-19) wave is unique in its clinical presentation and outcome. In this study, we compared the clinical characteristics and outcomes of COVID waves 2-5 in inpatient settings.

Methods: A retrospective study was conducted at the Sindh Infectious Diseases Hospital and Research Center on adult patients who were admitted with a positive COVID polymerase chain reaction from July 2020 to March 2022.

Squeezed Darcy-Forchheimer Casson nanofluid flow between horizontal plates under the effect of inclined magnetic field.

This article explores the properties of heat and mass transport for MHD Casson nanofluid flow between two horizontal plates by considering the Darcy-Forchheimer medium. The effects of a uniform inclined magnetic field are discussed numerically. A Darcy-Forchheimer medium is considered in the -direction between two plates.

Evaluation of potassium-enriched biochar and GA3 effectiveness for Improving wheat growth under drought stress.

Osmotic stress is a significant concern in agricultural crop production as it can harm crop growth, development, and productivity. Agriculture crops are particularly vulnerable to osmotic stress due to their reliance on water availability for various physiological processes. Organic amendments like activated carbon biochar and growth hormone gibberellic acid (GA3) can play a vital role.

Knowledge, beliefs and hesitancy among medical and non-medical university students toward COVID-19 vaccination in Punjab, Pakistan.

This study assessed the knowledge, beliefs, and hesitancy toward COVID-19 vaccination among medical (MS) and nonmedical students (NMS) in Punjab, Pakistan. An online cross-sectional survey was conducted by enrolling 624 MS and 476 NMS in the largest province of Pakistan, ., Punjab.

A rare case of diffuse ectasia in the coronary arteries and proximal aneurysm in the left anterior descending artery: A case report.

Introduction: Coronary artery aneurysm is defined as dilatation of a segment of coronary artery, greater than 1.5 times the diameter of the largest normal coronary artery of the patient. Major cause of coronary artery aneurysm is coronary artery disease.

An Adaptive Topology Management Scheme to Maintain Network Connectivity in Wireless Sensor Networks.

The roots of Wireless Sensor Networks (WSNs) are tracked back to US military developments, and, currently, WSNs have paved their way into a vast domain of civil applications, especially environmental, critical infrastructure, habitat monitoring, etc. In the majority of these applications, WSNs have been deployed to monitor critical and inaccessible terrains; however, due to their unique and resource-constrained nature, WSNs face many design and deployment challenges in these difficult-to-access working environments, including connectivity maintenance, topology management, reliability, etc. However, for WSNs, topology management and connectivity still remain a major concern in WSNs that hampers their operations, with a direct impact on the overall application performance of WSNs.

Integrated phosphorus nutrient sources improve wheat yield and phosphorus use efficiency under sub humid conditions.

Majority of Pakistani soils are deficient in phosphorus. Phosphorus is usually applied in form of synthetic fertilizer. However integrated use of P from synthetic and organic sources can be more profitable and beneficial on sustainable basis.

Taxonomy and distribution of agriculturally important plusiinae (Lepidoptera: Noctuidae) from southern Punjab, Pakistan.

Taxonomic identification and classifications of insect pest genera and of the subfamily Plusiinae is very compulsory due to their phytophagous nature and potential to damage the cash as well as cereal crops. Taxonomy plays a key role in proper not only in identification and classification of the pest but also in designing a successful managing strategy. In current study, specimens of and genera were collected from different geographical areas of south Punjab, Pakistan and their diagnostic features were examined following taxanomic keys.

The impact of horse purslane (Trianthema portulacastrum L.) infestation on soybean [Glycine max (L.) Merrill] productivity in northern irrigated plains of Pakistan.

Horse purslane (Trianthema portulacstrum L.) is an important weed of soybean crop capable of causing significant yield reduction. Therefore, this study assessed the impact of horse purslane and other weeds' infestation on the productivity of soybean.

Interference of horse purslane ( L.) and other weeds affect yield of autumn planted maize ( L.).

To assess comparative losses of (HP) relative to other weeds, the experiment was set during consecutive summer seasons 2018 and 2019 at the Research Farm MNS-University of Agriculture, Multan, Pakistan. Experiment consisted three replications which were laid out under randomized complete block design. Experiment consisted of ten treatments viz: weeds free (whole season), HP free till 20 Days after emergence (DAE), HP free till 40 DAE, HP free till 60 DAE, all weeds free 20 DAE, all weeds free 40 DAE, all weeds free 60 DAE, weedy check (all weeds), weedy check except HP and weedy check containing only HP.

Periodontitis is a risk factor for developing cardiovascular diseases.

Objective: To find out the link between periodontitis and cardiovascular disease while avoiding chronic infections that lead to heart diseases.

Methods: The case-control study was conducted at a tertiary care hospital in Lahore, Pakistan, from October 5, 2017, to January 5, 2018, and comprised patients of cardiovascular disease and healthy controls. Data was collected using questionnaire- based interviews.

Synthesis, in vitro α-glucosidase inhibitory potential and molecular docking study of thiadiazole analogs.

α-Glucosidase is a catabolic enzyme that regulates the body's plasma glucose levels by providing energy sources to maintain healthy functioning. 2-Amino-thiadiazole (1-13) and 2-amino-thiadiazole based Schiff bases (14-22) were synthesized, characterized by H NMR and HREI-MS and screened for α-glucosidase inhibitory activity. All twenty-two (22) analogs exhibit varied degree of α-glucosidase inhibitory potential with IC values ranging between 2.
