Efficient cooling systems are critical for maximizing the electrical efficiency of Photovoltaic (PV) solar panels. However, conventional temperature probes often fail to capture the spatial variability in thermal patterns across panels, impeding accurate assessment of cooling system performance. Existing methods for quantifying cooling efficiency lack precision, hindering the optimization of PV system maintenance and renewable energy output.

In response to the World Health Organization's research agenda of antimicrobial resistance in human health, this study appraised the antibacterial and antibiofilm synergistic activity of meropenem and ZnO nanoparticles (ZnO-NPs) combination against carbapenem-resistant Klebsiella pneumoniae (CRKP). The minimum inhibitory concentration (MIC) of meropenem in combination was found to be ~1/12 of its MIC alone. The results of microtiter dilution assay showed that the combination was more efficient in reducing the biofilm biomass than meropenem alone or ZnO-NPs alone.

Introduction: Frequent and long-term exposure to clinical alarms can cause emergency nurses to lose their trust in alarms, delay their response, and even disable or mute these alarms.

Methods: A cross-sectional study was conducted to assess emergency nurses' knowledge, perceptions, and practices toward clinical alarm fatigue and investigate the perceived obstacles they face when managing clinical alarms.

Results: Less than half of emergency nurses were unfamiliar with the term "alarm fatigue" (40.

Objectives: Hepatotoxicity is a severe outcome of methotrexate (MTX) therapy, limiting its clinical use and contributing to its related morbidity and mortality. This study investigated the hepatoprotective effects of nitazoxanide (NTZ), an antiprotozoal drug, against MTX-induced hepatotoxicity and whether endoplasmic reticulum (ER) stress-modulation underlies the expected beneficial effects of NTZ.

Methods: Thirty-six rats were allocated to six groups, one control group and five MTX groups, where induction of hepatotoxicity was achieved via injecting MTX (20 mg/kg).

Background: Nonalcoholic fatty liver disease (NAFLD) is the extremely usual reason of chronic liver disease, extending from simple hepatic steatosis (HS), nonalcoholic steatohepatitis (NASH) to advanced hepatic fibrosis and cirrhosis. Though orlistat is a Food and Drug Administration (FDA) approved drug for long-duration management of obesity, few cases of severe hepatic insult were declared. Melatonin is an efficient antioxidant; it also regulates metabolic processes that lead to fat accumulation and obesity.

Article Synopsis
  • Dermoscopy and trichoscopy are noninvasive diagnostic tools used to identify structures and conditions related to hair and scalp disorders that aren't visible to the naked eye.
  • A study involving 200 Egyptian children with focal non-cicatricial alopecia identified alopecia areata and tinea capitis as the most common diagnoses, with trichoscopy highlighting specific features that aid in distinguishing these conditions.
  • The findings suggest that incorporating trichoscopy into routine evaluations greatly enhances diagnostic accuracy and helps in the effective treatment of hair loss disorders in children.

Article Synopsis
  • Current chemical drugs are ineffective for tick control and there are no effective vaccines, leading to the urgent need for new control strategies.
  • Small interfering RNAs (siRNAs) have potential to help control parasites, but their effectiveness is limited by challenges in getting them to the RNA-induced silencing complex (RISC).
  • This study developed a delivery system using chitosan nanoparticles to successfully transfect siRNAs into parasites, which reduced target gene expression and inhibited parasite growth, opening new avenues for gene therapy and understanding host-parasite interactions.

Berberine (BBN) is a naturally occurring alkaloid as a secondary metabolite in many plants and exhibits several benefits including neuroprotective activities. However, data on the neuromodulating potential of nanoformulated BBN are still lacking. In the present study, BBN loaded within iron oxide nanoparticles (BBN-IONP) were prepared and characterized by transmission electron microscopy FTIR, X-ray photoelectron spectroscopy particle-size distribution, zeta potential, and HPLC.

With the increased directional drilling activities in the oil and gas industry, combined with the digital revolution amongst all industry aspects, the need became high to optimize all planning and operational drilling activities. One important step in planning a directional well is to select a directional tool that can deliver the well in a cost-effective manner. Rotary steerable systems (RSS) and positive displacement mud motors (PDM) are the two widely used tools, each with distinct advantages: RSS excels in hole cleaning, sticking avoidance and hole quality in general, while PDM offers versatility and lower operating costs.
