Environmentally hazardous radioactive isotopes of iodine may be released from a nuclear power plant as a by-product of uranium fission. The efficient and safe capture of volatile radioiodine is of great significance in the history of nuclear power plants. Due to its high volatility and carcinogenic characteristics, elimination of iodine gas (I) from air is the need of the hour from an environmental and health point of view.

Understanding the composition of bone tissue at the submicron level is crucial to elucidate factors contributing to bone disease and fragility. Here, we introduce a novel approach utilizing optical photothermal infrared (O-PTIR) spectroscopy and imaging coupled with machine learning analysis to assess bone tissue composition at 500 nm spatial resolution. This approach was used to evaluate thick bone samples embedded in typical poly(methyl methacrylate) (PMMA) blocks, eliminating the need for cumbersome thin sectioning.

Synthetic fabrics, especially polyester, are a primary source of microplastic fibers (MFs), but there is limited data on their accumulation and dose related health impact in living organisms. This study examined the effects of ingested polyester microfibers (PE-MFs) on hematology, histopathology, and serum biochemistry in albino mice. Mice were given varying doses of PE-MFs (100, 200, 400 and 800 μg/d/mice) for a duration of thirty-five days and a notable decreases in certain hematological parameters such as RBCs, Hb, and platelets, and increases in MCV and MCH was noted at (p < 0.

Background Ischemic stroke (IS) is a fatal complication of acute coronary syndrome (ACS). Factors that speed up IS development after ACS are understudied, especially in developing countries like Pakistan. Thus, this study was designed to identify the potential risk factors of IS in patients with a preceding episode of ACS.

Bio-transformations refer to the chemical modifications made by an organism on a chemical compound that often involves the interaction of plants with microbes to alter the chemical composition of soil or plant. Integrating bio-transformations and entomopathogenic fungi into litchi cultivation can enhance symbiotic relationships, microbial enzymatic activity in rhizosphere, disease suppression and promote overall plant health. The integration of biological formulations and entomopathogenic fungi can significantly influence growth, nutrient dynamics, physiology, and rhizosphere microbiome of air-layered litchi (Litchi chinensis Sonn.

This study evaluated the subsequent effect of photoperiods during incubation on post-hatch growth and stress response of commercial broiler chickens. A total of 875 Ross 308 broiler breeder (48 weeks of age) eggs were hatched using different durations (0, 4, 8, 12, 16, 20, and 24 h a day) of dichromatic light [green and red (495 to 750 nm); 2700 K; 250 lux; SUNJIE; China] throughout the whole period of incubation. A total of 50 0-day-old hatched straight run broiler chicks from each photoperiod during incubation were used to evaluate subsequent growth performance (feed intake, body weight, and feed conversion ratio); stress parameters (physical asymmetry, tonic immobility, and vocalization,); welfare traits (feather score and gait score); carcass traits (live weight, dressed weight, carcass yield, liver weight, gizzard weight, heart weight, abdominal fat weight, breast weight, and leg weight); and serum chemistry (globulin, total protein, cholesterol, glucose, and uric acid).

  • The study examined how various herbicides (atrazine, glyphosate, and acetochlor) affect the growth and health of a specific algae species (MASCC-0035) over a 96-hour exposure period.
  • Results showed that higher concentrations of herbicides led to a significant decrease in cell numbers and chlorophyll content, with glyphosate being the most damaging.
  • Additionally, herbicide exposure disrupted the algae's antioxidant system and lipid metabolism, indicating stress responses that could have broader ecological impacts, highlighting the importance of continued research in this area.

The opto-electronic properties and solar cell efficiency of halide perovskites ALiInBr (A = Rb, Cs) are investigated using density functional theory (DFT) through WEIN2k and SCAPS-1D. The electronic characteristic of ALiInBr (A = Rb, Cs) compounds reveal their direct bandgap semiconductor nature and are active in visible rang. The results indicate that substituting Cs with Rb causes a slight narrowing of the bandgap.

A diminutive chemical library of acyl thiotriazinoindole (ATTI) based bioactive scaffolds was synthesized, instigated by taking the economical starting material Isatin, through a series of five steps. Isatin was first nitrated followed by the attachment of pentyl moiety via nucleophilic substitution reaction. The obtained compound was reacted with thiosemicarbazide to obtain thiosemicarbazone derivative, which was eventually cyclized using basic conditions in water as solvent.

: Pre-eclampsia (PE) is a pregnancy-specific condition characterized by significant health risks for pregnant women worldwide due to its status as a multi-organ disorder. High blood pressure (hypertension) with or without proteinuria is usually considered an initial clinical sign of PE. The pathogenesis of pre-eclampsia is highly complex and likely involves multiple factors, including poorly developed uterine spiral arterioles, immunological issues, placental ischemia or infarction, and genetic abnormalities.

  • Trans fatty acids, particularly elaidic acid found in processed foods, can lead to serious liver, heart, and kidney disorders, including metabolic-associated fatty liver disease (MAFLD), cardiovascular disease (CVD), and chronic kidney disease (CKD).
  • A study on rabbits showed that those consuming Mujahid Ghee, high in elaidic acid, exhibited significantly higher levels of liver, heart, and kidney biomarkers compared to those consuming other fats like oleic acid or Kausar Ghee.
  • The study found that antioxidant enzyme activity was lower in rabbits consuming Mujahid Ghee, indicating that elaidic acid may worsen liver condition and contribute to heart and kidney issues.
