Micro- and nano-plastics (MNPs) and per- and polyfluoroalkyl substances (PFAS) are prevalent in ecosystems due to their exceptional properties and widespread use, profoundly affecting both human health and ecosystem. Upon entering the environment, MNPs and PFAS undergo various transformations, such as weathering, transport, and accumulation, potentially altering their characteristics and structural dynamics. Their interactions, governed by factors like hydrogen bonding, hydrophobic interactions, Van der Waals forces, electrostatic attractions, and environmental conditions, can amplify or mitigate their toxicity toward human health within ecological conditions.

Rheumatoid arthritis, a chronic autoimmune disorder characterized by joint inflammation, is thought to be exacerbated by bacterial infections, notably Proteus mirabilis. This study explores the combined effects of quercetin, a potent antioxidant and anti-inflammatory flavonoid, and chondroitin sulfate, known for its cartilage-protective properties, as a potential therapeutic approach. Molecular docking analyses revealed favourable interactions between these compounds and key pro-inflammatory cytokines IL-6 and TNF-α, suggesting their potential to disrupt inflammation-related signaling pathways.

Background: Low back pain (LBP), the primary cause of disability, is the most common musculoskeletal disorder globally and the primary cause of disability. Magnetic resonance imaging (MRI) studies are inconclusive and less sensitive for identifying and classifying patients with LBP. Hence, this study aimed to investigate the role of artificial intelligence (AI) models in the prediction of LBP using T2 weighted MRI image of the lumbar spine.

Background: Non-contrast Computed Tomography (NCCT) plays a pivotal role in assessing central nervous system disorders and is a crucial diagnostic method. Iterative reconstruction (IR) methods have enhanced image quality (IQ) but may result in a blotchy appearance and decreased resolution for subtle contrasts. The deep-learning image reconstruction (DLIR) algorithm, which integrates a convolutional neural network (CNN) into the reconstruction process, generates high-quality images with minimal noise.

White feces syndrome (WFS) is a multifactorial disease that affects global shrimp production. The diagnostic approach to identify WFS involves traditional and molecular scientific methods by examining histopathology, bioassays, PCR (polymerase chain reaction), and calorimetric estimation. The pathogenesis of WFS is closely associated with Vibrio spp.

Background: The most recent advances in Computed Tomography (CT) image reconstruction technology are Deep learning image reconstruction (DLIR) algorithms. Due to drawbacks in Iterative reconstruction (IR) techniques such as negative image texture and nonlinear spatial resolutions, DLIRs are gradually replacing them. However, the potential use of DLIR in Head and Chest CT has to be examined further.

The textile industry, with its extensive use of dyes and chemicals, stands out as a significant source of water pollution. Exposure to certain textile dyes, such as azo dyes and their breakdown products like aromatic amines, has been associated with health concerns like skin sensitization, allergic reactions, and even cancer in humans. Annually, the worldwide production of synthetic dyes approximates 7 × 10 tons, of which the textile industry accounts for over 10,000 tons.

This study investigates the individual and combined toxic effects of Bisphenol A (BPA) and Cadmium (Cd) in zebrafish, recognizing the complex mixture of pollutants organisms encounter in their natural environment. Examining developmental, neurobehavioral, reproductive, and physiological aspects, the study reveals significant adverse effects, particularly in combined exposures. Zebrafish embryos exposed to BPA + Cd exhibit synergistically increased mortality, delayed hatching, and morphological abnormalities, emphasizing the heightened toxicity of the combination.

Paraprobiotics, known as non-viable or ghost probiotics, have attracted attention for their benefits over live microbial cells. This study was designed to investigate the paraprobiotic effects of heat-killed Bacillus coagulans on the white leg shrimp Litopenaeus vannamei. The paraprobiotic formulation was prepared in three different concentrations including B.

Background: Electronic apex locators (EALs) are frequently used as adjuvant to radiographs in working length (WL) determination. The introduction of integrated apex locators (IALs) further simplified the root canal treatment by continuous monitoring of the apex while root canal shaping.

Aim: The aim of this study was to evaluate the efficacy of radiographs, EAL, and IAL in determining the WL in the presence of various irrigants.

Polycystic Ovary Syndrome (PCOS) and osteoporosis, though seemingly unrelated, exhibit intricate connections influenced by genetic and epigenetic factors. PCOS, characterized by elevated androgen levels, insulin resistance, and increased body weight, has historically been considered protective against bone fragility disorders. However, emerging research suggests that chronic inflammation, prevalent in PCOS, can adversely affect bone health.

Bacteria communicate with each other through contact-dependent and contact-independent mechanisms. While certain contact-dependent mechanisms, such as Type IV and Type VI, have received considerable attention, nanotubes-mediated communication among gut bacteria remains largely unknown. The purpose of this study is to demonstrate the presence of nanotube production in both gut commensal and gut pathogenic bacteria.

Shrimp aquaculture is a rapidly growing sector that makes a significant economic contribution. However, the aquaculture industry is confronted with significant challenges, and infectious diseases, notably Acute Hepatopancreatic Necrosis Disease (AHPND), have emerged as severe threat. AHPND is caused by pathogens carrying the pVA-1 plasmid, which expresses the PirAB toxin, and it has wreaked havoc in shrimp aquaculture, imposing substantial economic burdens.

Microplastics (MP), tiny plastic particles, can be ingested by fish through their habitat or contaminated food sources. When combined with a high-fat diet (HFD), MP exposure may lead to increased MP accumulation in fish and negative impacts on their health. However, the underlying mechanisms of how MP and HFD interact to promote fat accumulation in fish remain poorly understood.

Article Synopsis
  • Diverse microbial communities in the human body, known as the microbiome, are essential for health but can become imbalanced (dysbiosis), leading to chronic inflammation and damaging organs.
  • Changes in the microbiome's composition have been linked to non-communicable diseases, as specific pathogens produce toxic metabolites that impact host metabolism.
  • The review focuses on Enterobacteriaceae's role in these diseases, suggesting that understanding their metabolites could help identify new biomarkers and develop innovative treatments.

Pseudomonas aeruginosa (PA) is an opportunistic pathogen that causes healthcare-associated infection and high mortality in immunocompromised patients. It produces several virulence factors through quorum sensing (QS) mechanisms that is essential for subverting host immune system. Even front-line antibiotics are unable to control PA pathogenicity due to the emergence of antibiotic resistance.
