The new uranium(IV) chlorophosphate compounds UCl4(POCl3) and [U2Cl9][PCl4] have been synthesized by the solid-state reactions of U, P2O5, and PCl5 at 648 K; the compounds UCl3(PO2Cl2) and U2Cl8(POCl3) have been synthesized at 648 K with the same reactants plus added S. Their structures are, respectively, chainlike, a simple salt, three-dimensional, and sheetlike. From ab initio calculations, U2Cl8(POCl3) and UCl3(PO2Cl2) are found to be ferromagnetic, whereas UCl4(POCl3) is found to be antiferromagnetic. U2Cl8(POCl3) is a strong metal, whereas UCl3(PO2Cl2) is a weaker metal. In contrast, UCl4(POCl3) has a finite band gap, with a value of 0.35 eV.

Background: Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by oxidative stress and progressive motor neuron degeneration. This study evaluates the potential neuroprotective effects of caffeine in the Wobbler mouse, an established model of ALS.
Methods: Wobbler mice received caffeine supplementation (60 mg/kg/day) via drinking water, and key parameters, including muscle strength, NAD metabolism, oxidative stress, and motor neuron morphology, were assessed at critical disease stages.

Synthetic dyes, such as Congo red (CR), pose serious threats to human health and aquatic ecosystems because of their carcinogenicity and resistance to degradation, necessitating the development of efficient and eco-friendly remediation strategies. In this study, silver nanoparticles (AgNPs) were synthesized via a green method using Ocimum sanctum (holy basil) leaf extract and applied for CR dye removal from aqueous solutions. The adsorption process was optimized using response surface methodology (RSM) based on Box-Behnken design (BBD), evaluating the influence of key parameters including pH, AgNP dosage, initial dye concentration, contact time, and temperature.

Babesia bigemina, a tick-borne protozoan parasite, is one of the main causative agents of bovine babesiosis, a disease with significant economic impact on the cattle industry. One of the key enzymes involved in the parasite's metabolism is lactate dehydrogenase (LDH), which plays an essential role in the anaerobic glycolytic pathway by catalysing the conversion of pyruvate to lactate. In this study, B.

Small cell lung cancer (SCLC) is a highly aggressive type of lung cancer, characterized by rapid proliferation, early metastatic spread, frequent early relapse and a high mortality rate. Recent evidence has suggested that innervation has an important role in the development and progression of several types of cancer. Cancer-to-neuron synapses have been reported in gliomas, but whether peripheral tumours can form such structures is unknown.
