Breakthrough COVID-19 Infection Among the General Community, Frontline Workers, and Healthcare Workers During the Second and Third Wave in North India: A Longitudinal Study.

Background: Vaccination is among the most important public health tools for preventing the harm caused by communicable diseases. This was particularly true in the case of COVID-19 vaccination during the COVID-19 pandemic. However, no vaccine is 100% effective, and all carry the risk of breakthrough infection in vaccinated individuals.

Assessment of health status and its correlation with lung function in patients with chronic obstructive pulmonary disease: a study from a tertiary care center in north India.

The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 recommends a comprehensive multidimensional assessment for patients with chronic obstructive pulmonary disease (COPD) and stresses the need for evaluation of their health status and quality of life (QOL). The COPD assessment test (CAT), clinical COPD questionnaire (CCQ), and St. George respiratory questionnaire (SGRQ) are recommended by GOLD for such assessments.

Assessment of diabetes risk profile in a rural population of northern India using the Indian Diabetes Risk Score - A community-based study.

Background: Diabetes is one of the leading killers among noncommunicable diseases of the present time and poses a considerable burden to the society in terms of public health. The Indian Diabetes Risk Score (IDRS) can be used as a risk assessment tool to estimate the population at risk and plan appropriate interventions. The present study was conducted to assess the diabetes risk profile of a rural population of Punjab by using IDRS.

Study to evaluate the relation between weight gain in infants and occurrence of retinopathy of prematurity.

Purpose: Retinopathy of prematurity (ROP) is a leading cause of childhood blindness. Capturing serial daily postnatal weight gain can act as an innovative, low-cost method of risk stratification. We aim to study the relation between weight gain in infants and occurrence of ROP.

Au-Nanoplasmonics-Mediated Surface Plasmon-Enhanced GaN Nanostructured UV Photodetectors.

The nanoplasmonic impact of chemically synthesized Au nanoparticles (Au NPs) on the performance of GaN nanostructure-based ultraviolet (UV) photodetectors is analyzed. The devices with uniformly distributed Au NPs on GaN nanostructures (nanoislands and nanoflowers) prominently respond toward UV illumination (325 nm) in both self-powered as well as photoconductive modes of operation and have shown fast and stable time-correlated response with significant enhancement in the performance parameters. A comprehensive analysis of the device design, laser power, and bias-dependent responsivity and response time is presented.

Gene Expression Profiling of Human Adipose Tissue Stem Cells during 2D versus 3D Adipogenesis.

Much of the current understanding on molecular and cellular events of adipose developmental biology comes from monolayer cell culture models using preadipocyte cell lines, although in vivo adipose tissue consists of a much more complex three-dimensional microenvironment of diverse cell types, extracellular network, and tissue-specific morphological and functional features. Added to this fact, the preadipocytes, on which the adipogenesis mechanisms are mostly explored, possess some serious limitations (e.g.

Flower Shaped Gold Nanoparticles: Biogenic Synthesis Strategies and Characterization.

Microbes can serve as mediators for the fabrication of complicated nano-structures, obviating the tedious and time-consuming methods of synthesis. The shape of a nanoparticle has a very prominent role in defining the functionality in prospective arenas. So, the flower shaped nanoparticles are in focus nowadays due to their enhanced electrocatalytic and optical properties as compared to the spherical ones.

Minimizing the potential of cancer recurrence and metastasis by the use of graphene oxide nano-flakes released from smart fiducials during image-guided radiation therapy.

An increasing number of studies show that cancer stem cells become more invasive and may escape into blood stream and lymph nodes before they have received a lethal dose during radiation therapy. Recently, it has been found that graphene oxide (GO) can selectively inhibit the proliferative expansion of cancer stem cells across multiple tumor types. In this study, we investigate the feasibility of using GO during radiotherapy to synergistically inhibit cancer stem cells, and lower the risk of cancer metastasis and recurrence.

Robust genetic transformation of sorghum ( L.) using differentiating embryogenic callus induced from immature embryos.

Background: Sorghum ( L.) is one of the world's most important cereal crops grown for multiple applications and has been identified as a potential biofuel crop. Despite several decades of study, sorghum has been widely considered as a recalcitrant major crop for transformation due to accumulation of phenolic compounds, lack of model genotypes, low regeneration frequency and loss of regeneration potential through sub-cultures.

Association of tuberculosis and diabetes Mellitus: an analysis of 1000 consecutively admitted cases in a tertiary care hospital of North India.

Introduction: The association of Tuberculosis and Diabetes Mellitus is a cause of concern for the health sector. The coexistence of these two highly prevalent diseases has made the already existing treatments very complex. This issue is of particular significance to developing countries like India that bear a significant burden of these two diseases.

Modification of Seed Oil Composition in Arabidopsis by Artificial microRNA-Mediated Gene Silencing.

Various post transcriptional gene silencing strategies have been developed and exploited to study gene function or engineer disease resistance. The recently developed artificial microRNA strategy is an alternative method of effectively silencing target genes. The Δ12-desaturase (FAD2), Fatty acid elongase (FAE1), and Fatty acyl-ACP thioesterase B (FATB) were targeted with amiR159b-based constructs in Arabidopsisthaliana to evaluate changes in oil composition when expressed with the seed-specific Brassica napus truncated napin (FP1) promoter.

Colorimetric detection of nucleic acid signature of shiga toxin producing Escherichia coli using gold nanoparticles.

Enterohemorrhagic E. coil (EHEC) serotype O157:H7 is one of the major pathogens, responsible for the severe disease outbreaks. EHEC causes diseases in humans through production of shiga-like toxin leading to bloody diarrhea.
