Recent Advancements and Applications of Nanosensors in Oral Health: Revolutionizing Diagnosis and Treatment.

Advances in the field of nanomaterials are laying the foundation for the fabrication of nanosensors that are sensitive, selective, specific, cost-effective, biocompatible, and versatile. Being highly sensitive and selective, nanosensors are crucial in detecting small quantities of analytes and early diagnosis of diseases. These devices, operating on the nanoscale, detect signals, such as physical, chemical, optical, electrochemical, or biological, and then transduce them into a readable form.

A surrogate ELISA to select high titer human convalescent plasma for treating immunocompromised patients infected with SARS-CoV-2 variants of concern.

Background: The emergence of new SARS-CoV-2 variants poses a new challenge for the treatment of immunocompromised patients against COVID-19. In this context, high titer COVID-19 Convalescent Plasma (CCP) is one of the few available therapeutics for these patients. We have revisited the selection of CCP samples and its efficacy against Omicron XBB.

Repurposed drugs as PCSK9-LDLR disruptors for lipid lowering and cardiovascular disease therapeutics.

The PCSK9 protein binds to LDL receptors (LDLR), leading to their degradation and reduced expression on cell surfaces. This decreased the clearance of LDL cholesterol from the bloodstream, thereby increasing the risk of coronary artery diseases. Targeting the PCSK9-LDL receptor interaction is crucial for regulating LDL cholesterol levels and preventing cardiovascular disease.

Assessing strategies to measure hidden per- and polyfluoroalkyl substances (PFAS) in groundwater and to evaluate adsorption remediation efficiencies.

The widespread presence of per- and polyfluoroalkyl substances (PFAS) in the environment, driven by extensive industrial use, has raised global concerns due to their persistence and adverse health effects. Despite the increased regulatory focus on a sub-set of well-known PFAS, over 12,000 compounds exist, many poorly characterized. Our study assessed hidden PFAS concentrations, undetectable by standard LC-MS/MS analysis, in contaminated groundwater.

Challenges and opportunities in engineering next-generation 3D microelectronic devices: improved performance and higher integration density.

In recent years, nanotechnology and materials science have evolved and matured, making it increasingly easier to design and fabricate next-generation 3D microelectronics. The process has changed drastically from traditional 2D microelectronics, resulting in improved performance, higher integration density, and new functionalities. As applications become more complex and power-intensive, this technology can address the demands of high-performance computing, advanced sensors, and cutting-edge communication systems wearable, flexible devices, To manufacture higher-density microelectronics, recent advances in the fabrication of such 3D devices are discussed.

Childhood trauma in bipolar affective disorder: A case control study.

Background: The etiology of Bipolar Affective Disorder (BPAD) is influenced by a variety of factors, possibly related to gene-environment interactions. Childhood trauma (CT) has been associated with an increased risk of developing BPAD. It also impacts the course of illness.

Building psychological resilience among families of service personnel.

Psychological resilience means adapting positively to adversity. This is armed forces' very context and function-encountering, enduring, and overcoming challenging situations through resilience. Scientific study of psychological resilience has moved from individual, to process, onward to developmental trajectories, and to neuro-biological underpinnings.

Case report: exome sequencing identified mutations in the and genes in a case of osteoporosis with recurrent fractures and extraskeletal manifestations.

Background: Genetic mutations have been reported in a number of bone disorders with or without extra-skeletal manifestations. The purpose of the present study was to investigate the genetic cause in a middle-aged woman with osteoporosis, recurrent fractures and extraskeletal manifestations.

Methods: A 56-year-old Indian woman presented to the clinic with complaints of difficulty in walking, recurrent fractures, limb bending, progressive skeletal deformities, and poor overall health.

T cell epitope mapping reveals immunodominance of evolutionarily conserved regions within SARS-CoV-2 proteome.

As SARS-CoV-2 variants continue to emerge capable of evading neutralizing antibodies, it has become increasingly important to fully understand the breadth and functional profile of T cell responses to determine their impact on the immune surveillance of variant strains. Here, sampling healthy individuals, we profiled the kinetics and polyfunctionality of T cell immunity elicited by mRNA vaccination. Modeling of anti-spike T cell responses against ancestral and variant strains of SARS-CoV-2 suggested that epitope immunodominance and cross-reactivity are major predictive determinants of T cell immunity.

Identifying Novel Inhibitors for Dengue NS2B-NS3 Protease by Combining Topological similarity, Molecular Dynamics, MMGBSA and SiteMap Analysis.

Introduction: DENV NS2B-NS3 protease inhibitors were designed based upon the reference molecule, 4-(1,3-dioxoisoindolin-2-yl)-N-(4-ethylphenyl) benzenesulfonamide, reported by our team with the aim to optimize lead compound via rational approach. Top five best scoring molecules with zinc ids ZINC23504872, ZINC48412318, ZINC00413269, ZINC13998032 and ZINC75249613 bearing 'pyrimidin-4(3H)-one' basic scaffold have been identified as a promising candidate against DENV protease enzyme.

Methods: The shape and electrostatic complementary between identified HITs and reference molecules were found to be Tanimotoshape 0.

In-silico immunoinformatic vaccine design for Treponema denticola ergothionase.

Background: Treponema denticola, a well-studied oral spirochete, adheres, invades, and damages periodontal tissues - gram-negative, anaerobic Treponema denticola. In previous research, sub-gingival spirochetes have correlated positively with dental plaque score, pocket, and clinical attachment level measurements. Hence, the study aims to design an immunoinformatic vaccine using a reverse vaccinology approach against Treponema denticola ergothionase.

Rationally Designed G-Quadruplex Selective "Turn-On" NIR Fluorescent Probe with Large Stokes Shift for Nucleic Acid Research-Based Applications.

Guanine-rich DNA/RNA sequences can form Hoogsteen bonds to adopt noncanonical secondary structures called G-quadruplexes, and these have been associated with diverse cellular processes. There has been considerable research interest in the design of G4-interacting ligands for cellular probing of the G4 structure and understanding its associated biological function. Most of the fluorescent G4 ligands either do not have significant selectivity over other nucleic acid structures, have high Stokes shift, or are not in the near-infrared (NIR) region, which limits its cellular visualization.

Therapeutic targeting of Wnt antagonists by small molecules for treatment of osteoporosis.

Wnt signaling is one of the key regulators of bone development and homeostasis. Wnt signaling regulates key biological events, including stem cell fate and osteoblast and osteoclast activity, leading to the maintenance of bone mass and strength. Wnt ligands are secreted glycoproteins that bind to Frizzled (FZD) receptors and their coreceptors, lipoprotein receptor-related proteins-5/6 (LRP5/6).

Effectiveness of Multifaceted Lifestyle Interventions in Prediabetic Adults: A Field Study in an Urban Slum Population of Pune, India.

Introduction Adults with diabetes have an increased risk of hypertension, heart attack, and stroke than those without diabetes. Diagnosing prediabetes at an early stage can significantly reduce the risk of diabetes through simple interventions such as lifestyle modifications. Lifestyle modifications such as weight loss combined with regular physical exercise and a healthy diet can help delay or prevent the progression of diabetes.

Accelerated Radiotherapy Alone Versus Chemoradiation in Locally Advanced Carcinoma Cervix: Long-Term Outcomes.

Introduction Chemoradiation (CRT) is the standard of care for the treatment of carcinoma cervix, more benefits of CRT are seen in the early stage as compared to a locally advanced stage. Altered fractionation such as accelerated radiotherapy (ART) in locally advanced carcinoma cervix has not been explored much. Here, we have reported the long-term outcome of ART in comparison to conventional CRT in locally advanced cervical cancer patients.
