The widespread reliance on single-use plastics (SUPs) has fostered a global throwaway culture, especially in the food packaging industry, where convenience and low cost have driven their adoption, posing serious environmental threats, particularly to marine ecosystems and biodiversity. Edible and ecofriendly packaging made from millet, specifically sorghum ( () Moench), is a promising solution to mitigate SUP consumption and promote sustainability. This study explores the development of edible sorghum bowls, enhanced through roasting and incorporating 3 g of hibiscus and rose flower powders.

The energy-exergy and environ-economic (4E) analysis was conducted on a solar still with and without a hybrid thermal energy storage system (TESS) and a solar air heater. The proposed solar still was modified by integrating a rectangular aluminium box filled with paraffin wax and black gravel as the TESS and coupled with a solar air heater. Paraffin wax was selected due to its widespread availability and proven effectiveness in accelerating desalination, improving process uniformity, and maintaining optimal temperature levels.

Gestational Weight Gain (GWG) modulates pregnancy outcomes and long-term offspring metabolic health. The 2009 Institute of Medicine (IOM) GWG recommendations have largely been validated in Caucasian and mono-ethnic East Asian cohorts. Asians are at higher metabolic risk at a lower body mass index (BMI), and this has prompted the World Health Organization (WHO) to identify lower BMI cut-offs for risk evaluation amongst Asians.

This study explores the thermal conductivity and viscosity of water-based nanofluids containing silicon dioxide, graphene oxide, titanium dioxide, and their hybrids across various concentrations (0 to 1 vol%) and temperatures (30 to 60 °C). The nanofluids, characterized using multiple methods, exhibited increased viscosity and thermal conductivity compared to water, with hybrid nanofluids showing superior performance. Graphene oxide nanofluids displayed the highest thermal conductivity and viscosity ratios, with increases of 52% and 177% at 60 °C and 30 °C, respectively, for a concentration of 1 vol% compared to base fluid.

Article Synopsis
  • The study focuses on simulating and optimizing CsPb.Zn.IBr-based perovskite solar cells (PSCs) using the SCAPS-1D simulator to explore how different hole transport layers (HTL) and electron transport layers (ETL) impact device performance.
  • After optimizing the HTL, the best power conversion efficiency (PCE) recorded was 16.59% with the FTO/SnS/CsPb.Zn.IBr/MoS/Au structure, while further improvements in thickness and charge carrier densities led to a maximum PCE of 21.05% for the FTO/ZnSe/CsPb.Zn.IBr/MoS/Au configuration.

The development of a fatal, clonal, autonomously proliferating CD4-CD8- chimeric antigen receptor (CAR)+ peripheral T-cell lymphoma (PTCL) occurred 1 month after a patient received treatment with tisagenlecleucel for relapsed primary central nervous system lymphoma. The PTCL had a clonal T-cell receptor rearrangement, which was already detectable in the apheresis product for CAR T-cell manufacturing and 7 months earlier for autologous transplantation. Somatic and mutations in CD34+ stem cells and their progeny were detected in the PTCL, in the apheresis specimen that was obtained for CAR T-cell production, and in the autotransplant.

  • Processed foods are loaded with food additives that enhance flavor, texture, and shelf life, but many of these additives can act as endocrine-disrupting chemicals (EDCs).
  • EDCs can interfere with hormone regulation and cause health issues like obesity, diabetes, and reproductive problems, as well as developmental abnormalities.
  • The review seeks to identify harmful food additives, explore their uses in the food industry, and propose strategies for reducing such additives in favor of safer alternatives to safeguard human health.

Danger-associated molecular patterns (DAMPs) are released on the onset of tissue injury or death, which tend to trigger innate immunity and regulate various immune pathways. Among the various DAMP molecules, S100A8 and S100A9 belonging to Ca binding proteins with EF-hands and Zn ion binding sites have been implicated in aggravating the pathogenesis of rheumatoid arthritis (RA), upon interaction with pattern recognition receptors (PRR) such as TLR4, RAGE and CD36 receptors. Thus, the present study aims to assess the effect of Ca or Zn ions on the interaction of S100A8 and S100A9 proteins towards the PRRs.

Microplastics have polluted agricultural soils, posing a substantial risk to crop productivity. Moreover, the presence of microplastic pollution has caused a disturbance in the composition of the microbial community in the soil surrounding plant roots, therefore impacting the growth of beneficial bacteria. A study was conducted to examine if humic acid (HA) can counteract the harmful effects of microplastics (MPs) on the growth of black gram crops and the composition of the rhizosphere soil microbial community, to reduce the negative impacts of microplastics on these microorganisms and crops.

Hypertension is associated with poor outcome and higher mortality in patients with ischemic stroke. The impairment of adaptive vascular mechanisms under hypertensive condition compromises collateral blood flow after arterial occlusion in patients with acute ischemic stroke resulting in hypoperfusion. The increased oxidative stress caused by hypoperfusion is thought to be a trigger for the rapid evolution of ischemic infarct volume under hypertensive condition.
