Investigation of electrochromic performances of multicolor VO devices fabricated at low processing temperature.

Sci Rep

January 2025

Centre for Advanced Devices and Systems, Faculty of Engineering, Multimedia University, Persiaran Multimedia, 63100, Cyberjaya, Selangor, Malaysia.

In recent decades, poorly insulated windows have increased the energy consumption of heating and cooling systems, thus contributing to excessive carbon dioxide emissions and other related pollution issues. From this perspective, the electrochromic (EC) windows could be a tangible solution as the indoor conditions are highly controllable by these smart devices even at a low applied voltage. Literally, vanadium pentoxide (VO) is a renowned candidate for the EC application due to its multicolor appearance and substantial lithium insertion capacity.

Preterm birth exposes the neonate to hypoxic-ischaemic and excitotoxic insults that impair neurodevelopment and are magnified by the premature loss of placentally supplied, inhibitory neurosteroids. The cerebellum is a neuronally dense brain region, which undergoes critical periods of development during late gestation, when preterm births frequently occur. We propose that neurosteroid replacement therapy using tiagabine and zuranolone will protect the cerebellum against preterm-associated insults.

The research conducted in this preclinical study assesses QazCovid-live, a live attenuated COVID-19 vaccine created in Kazakhstan, by conducting preclinical evaluations of safety, immunogenicity, and allergenicity in various animal models, including mice, rats, hamsters, and guinea pigs. The vaccine, developed by attenuating SARS-CoV-2 via numerous Vero cell passages, had no significant adverse effects in acute and subacute toxicity assessments, even at elevated dosages. Allergenicity testing indicated the absence of both immediate and delayed hypersensitivity reactions.

The Pap smear is widely recognized in medicine as the single most successful contributor to cancer screening and preventative care. Women have Dr. George Papanicolaou (1870-1962) to thank for this groundbreaking contribution to their healthcare-a discovery that, fascinatingly, was made incidentally during his study of ovulation cycles in guinea pigs.

A new genus and a new species of isosporoid coccidium (Apicomplexa: Conoidasida: Eimeriorina) are described and illustrated from green tree frogs () (Anura: Hylidae) imported from Papua New Guinea and Indonesia. The described species has disporocystic and tetrasporozoic oocysts without a Stieda body. Nine species originally belonging to the genus Schneider, 1881 in the family Eimeriidae Minchin, 1903 described from Anura are recognized as members of the new genus and new combinations of the species names are proposed.

This paper analyses the credit constraints' effect on non-farm entrepreneurship entry decisions in Benin. Using data from a sample of 512 farmers, we determine the factors that influence credit constraints and then assess the effect of credit constraints on non-farm entrepreneurship decisions based on an endogenous switching probit model and propensity score matching (PSM). The results of endogenous switching regression reveal that age and access to extension services are the main determinants of credit constraints while age, sex, household size, marital status, education level and farmer-based organisation (FBO) membership significantly increase farmers' decisions to engage in non-farm entrepreneurship.

Background: Sensorineural hearing loss (SNHL) is the most common sensory deficit worldwide. Current solutions for SNHL, including hearing aids, cochlear implants, and hearing assistive devices, do not provide consistent results and fail to address the underlying pathology of hair cell and ganglion cell damage. Stem cell therapy is a cornerstone in regenerative medicine.

Cinnamic acid lowers blood pressure and reverses vascular endothelial dysfunction in rats.

J Food Drug Anal

December 2024

Cardiovascular Research Group, Department of Pharmacy, COMSATS University Islamabad, Abbottabad Campus, University Road, Abbottabad-22060, KP, Pakistan.

Cinnamic acid (CA) possesses important cardiovascular effects such as cardioprotective, antiatherogenic, antihyperlipidemic and antioxidant, which predicts its potential role in the treatment of hypertension. The study was executed to investigate the antihypertensive potential of CA in Sprague Dawley (SD) rats followed by evaluation in diverse vascular preparations. Invasive blood pressure monitoring technique was used in normotensive and hypertensive rats, under anesthesia.

Precise estimation of rock petrophysical parameters are seriously important for the reliable computation of hydrocarbon in place in the underground formations. Therefore, accurately estimation rock saturation exponent is necessary in this regard. In this communication, we aim to develop intelligent data-driven models of decision tree, random forest, ensemble learning, adaptive boosting, support vector machine and multilayer perceptron artificial neural network to predict rock saturation exponent parameter in terms of rock absolute permeability, porosity, resistivity index, true resistivity, and water saturation based on acquired 1041 field data.

BMJ Paediatr Open

December 2024

Department of Community Paediatrics, South Western Sydney Local Health District, Liverpool, New South Wales, Australia.

Background: The Convention on the Rights of the Child states that children need to be protected from 'any work that is likely to be hazardous or to interfere with the child's education, or to be harmful to the child's health or physical, mental, spiritual, moral or social development'. We aimed to determine the prevalence and correlates of child labour in five low-income African countries using the sixth wave of UNICEF Multiple Indicator Cluster Surveys (MICS6).

Methods: Data on child labour, reported by the household respondent for a randomly selected child (5-17 years), were extracted from MICS6 reports from Chad, Guinea Bissau, Malawi, Sierra Leone and Togo.

Article Synopsis
  • Tuberculosis (TB) is a major health issue in Guinea, with many cases going undetected; an intensified case finding strategy involved pharmacies and drug outlets targeting customers buying cough suppressants.
  • A study conducted in Conakry involved screening 916 individuals for TB, resulting in a 14% bacteriologically confirmed TB diagnosis, with gender and age influencing diagnosis likelihood.
  • The intervention cost approximately $32.66 per person referred and $237.45 for those diagnosed, showing that using pharmacies as a TB detection point is both feasible and effective in boosting detection rates.

Department of Environmental and Radiological Health Sciences, College of Veterinary Medicine and Biomedical Sciences, Colorado State University, Fort Collins, Colorado, United States of America.

Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb) infection, is a chronic inflammatory disease. Although typically associated with inflammation of the lungs and other peripheral tissues, increasing evidence has uncovered neurological consequences attributable to Mtb infection. These include deficits in memory and cognition, increased risk for neurodegenerative disease, and progressive neuropathology.
