Photothermal therapy (PTT) has emerged as an effective cancer treatment strategy, which utilizes photothermal agents that accumulate at tumor sites and induce localized hyperthermia when irradiated. Near-infrared II (NIR II) fluorophores, such as the polymethine cyanine-based photothermal dye IR1061, exhibit higher temporal resolution and better tissue penetration, thereby making them promising candidates for PTT. However, challenges such as the low water solubility and short circulation times of these dyes limit their biological applications.

Diabetic cardiomyopathy (DbCM) is a silent and complex condition involving numerous signaling pathways that impair cardiomyocyte metabolism and cardiac performance. Striatin (STRN) is a multifaceted protein that binds metabolic proteins, yet its role in diabetic heart remains unexplored. Here we characterized the cardiac STRN interactome by performing immunoprecipitation on left ventricle (LV) proteins from control and diabetic hearts (rats treated with streptozotocin for 24 weeks) to dissect its derivative protein complex.

Vancomycin intermediate-resistant Staphylococcus aureus (VISA) is a pathogen of concern. VraS, a histidine kinase, facilitates the VISA phenotype. Here, we reveal a benzoxazolyl urea (chemical 1) that directly inhibits VraS and enhances vancomycin to below the clinical breakpoint against an archetypal VISA strain, Mu50.

Unlabelled: Bacterial genomic mutations in have been detected in isolated resistant clinical strains, yet their mechanistic effect on the development of antimicrobial resistance remains unclear. The resistance-associated regulatory systems acquire adaptive mutations under stress conditions that may lead to a gain of function effect and contribute to the resistance phenotype. Here, we investigate the effect of a single-point mutation (T331I) in VraS histidine kinase, part of the VraSR two-component system in VraSR senses and responds to environmental stress signals by upregulating gene expression for cell wall synthesis.

A pot experiment was conducted to investigate the role of thiourea exogenous application (0 mg/L and 100 mg/L) on the morphological, physiological, and yield traits of two varieties of tomato (Naqeeb and Nadir) under different salt stress treatments (0, 60, and 120 mM) in completely randomized design (CRD). The imposition of salinity by rooting medium showed that salt stress reduced plant height by 20%, fresh shoot weight by 50%, dry shoot weight by 78%, fresh root weight by 43%, dry root weight by 84%, root length by 34%, shoot length by 32%, shoot K by 47%, Ca by 70%, chlorophyll a by 30%, chlorophyll b by 67%, and the number of seeds per berry by 53%, while shoot Na ions were increased by 90% in comparison to those grown with control treatment. However, the exogenous application of thiourea significantly enhanced dry root weight by 25% and the number of seeds per berry by 20% in comparison to untreated plants with thiourea when grown under salt stress.

Iron homeostasis is vital for normal physiology, but in the majority of circumstances, like iron overload, this equilibrium is upset leading to free iron in the plasma. This condition with excess iron is known as hemochromatosis, which has been linked to many side effects, including cancer and liver cirrhosis. The current research aimed to investigate active molecules from Streptomyces sp.

  • High levels of arsenic (As) and fluoride (F), along with microbial pathogens, are a significant public health risk in semiarid regions, affecting over 240 million people, including those in Pakistan.
  • Groundwater around coal mines in Quetta shows concerning concentrations of As (0.2-16.6 µg/L) and F (0.4-18.5 mg/L), with mining areas experiencing even higher levels and various geochemical factors influencing these contaminants.
  • A health risk assessment indicates that over 64% of groundwater samples exceed WHO guidelines for As and F, posing greater carcinogenic and non-carcinogenic risks to children, highlighting a critical need for improved water quality and management.

  • The contamination of water bodies by heavy metals like copper, lead, mercury, and cadmium is a major environmental and health concern, requiring new remediation strategies that are sustainable and cost-effective.
  • Traditional methods for removing these metals are often expensive and inefficient, leading to the exploration of alternative solutions.
  • Biochar, a carbon-rich material made from organic waste through pyrolysis, shows promise as a low-cost adsorbent for effectively capturing heavy metals in contaminated water, with its effectiveness influenced by factors like feedstock type and production processes.

Retrosynthesis prediction is a fundamental problem in organic chemistry and drug synthesis. We proposed an end-to-end deep learning model called CTsynther (Contrastive Transformer for single-step retrosynthesis prediction model) that could provide single-step retrosynthesis prediction without external reaction templates or specialized knowledge. The model introduced the concept of contrastive learning in Transformer architecture and employed a contrastive learning language representation model at the SMILES sentence level to enhance model inference by learning similarities and differences between various samples.
