Pt-supported on N-doped carbon/TiO nanomaterials derived from NH-MIL-125 for efficient photo-thermal RWGS reaction.

To mitigate carbon dioxide (CO) emissions and advance carbon neutrality, the conversion of CO into value-added fuels and chemicals via the reverse water-gas shift (RWGS) reaction is recognized as a promising approach. In this study, we designed platinum (Pt)-loaded nitrogen-doped carbon composite dual-phase titanium dioxide (TiO) nanomaterials to achieve efficient photo-thermal performance in the RWGS reaction. The incorporation of Pt, nitrogen doping, and the selection of an appropriate calcination temperature enhance light responsiveness and reduce the recombination of photo-generated carriers, thereby improving the efficiency of the photo-thermal RWGS reaction.

Physiopathological Roles of White Adiposity and Gut Functions in Neuroinflammation.

White adipose tissue (WAT) and the gut are involved in the development of neuroinflammation when an organism detects any kind of injury, thereby triggering metainflammation. In fact, the autonomous nervous system innervates both tissues, although the complex role played by the integrated sympathetic, parasympathetic, and enteric nervous system functions have not been fully elucidated. Our aims were to investigate the participation of inflamed WAT and the gut in neuroinflammation.

Myeloproliferative Neoplasm-like Mutations of Calreticulin Induce Phenotypes Associated with Calreticulin Dysfunction in .

In previous research, we created a model with homozygous mutations in calreticulin similar to those found in patients with essential thrombocythemia (ET) and primary myelofibrosis (PMF), two myeloproliferative neoplasms (MPNs). This model, lacking JAK orthologs, enabled us to examine the transcriptomic effects caused by mutant calreticulin without the influence of JAK/STAT activation, the primary pathogenic mechanism associated with calreticulin mutations known to date. Most of the gene expression changes observed seemed to be due to a partial loss of protein function, with the alteration of the extracellular matrix being particularly notable.

Assessing the impact of ecological, climatic, and socioeconomic factors on age-specific malaria incidence in India: a mixed-model approach using the Global Burden of Disease Study (2010-2019).

Pressure Ulcers and Nutrients: From Established Evidence to Gaps in Knowledge.

Pressure ulcers (PUs) are caused by continuous pressure or friction on the skin that damages tissue, especially over bony prominences. A critical factor in the development and progression of PUs is poor nutritional status, which often involves deficiencies in essential nutrients such as proteins, vitamins (A, C, D, E, K, and the B complex), and trace elements (including zinc, selenium, copper, iron, and manganese). These micronutrients are vital for effective wound healing, as they play significant roles in cellular repair, immune function, and tissue regeneration.

Synthesis of Chromene-linked Bis-indole Derivatives as Selective Tumor-associated Carbonic Anhydrase IX Inhibitors.

Background: Sulfonamide derivatives are well-reported hCA IX inhibitors; however, they inhibit all types of hCA without any selectivity, leading to severe adverse effects. Hence, developing a novel nonsulfonamide class of tumor-associated hCA IX inhibitors through non-classical inhibition may provide greater selectivity and better pharmacokinetics.

Objective: The objective of this study was to develop non-sulfonamide derivatives as potential human carbonic anhydrase (hCA) inhibitors and develop a new series of chromene-linked bis-indole derivatives.

Exploring the therapeutic mechanisms of millet in obesity through molecular docking, pharmacokinetics, and dynamic simulation.

Obesity, a prevalent global health concern, is characterized by excessive fat accumulation, which confers significant nutritional and health risks, including a shortened lifespan and diminished wellbeing. Central to the regulation of energy balance and food intake is the fat mass and obesity-associated (FTO) protein, which modulates the interplay between caloric consumption and energy expenditure. Given its pivotal role in obesity regulation, the identification of effective inhibitors targeting the FTO protein is imperative for developing therapeutic interventions.
