Nuclear Transcription Factor Detection.

Cellular fate is determined by the activity of nuclear transcription factors. Here, we describe a series of protocols for detecting transcription factors at both the transcript and protein levels in human adipose cells. Methods for analysis of transcript include RNA extraction, reverse transcription polymerase chain reaction (RT-PCR), endpoint PCR, and RT-qPCR.

Copper-Cystine Biohybrid-Embedded Nanofiber Aerogels Show Antibacterial and Angiogenic Properties.

Copper-cystine-based high aspect ratio structures (CuHARS) possess exceptional physical and chemical properties and exhibit remarkable biodegradability in human physiological conditions. Extensive testing has confirmed the biocompatibility and biodegradability of CuHARS under diverse biological conditions, making them a viable source of essential Cu. These ions are vital for catalyzing the production of nitric oxide (NO) from the decomposition of S-nitrosothiols (RSNOs) found in human blood.

PEDOT/CNT Flexible MEAs Reveal New Insights into the Clock Gene's Role in Dopamine Dynamics.

Substantial evidence has shown that the Circadian Locomotor Output Cycles Kaput (Clock) gene is a core transcription factor of circadian rhythms that regulates dopamine (DA) synthesis. To shed light on the mechanism of this interaction, flexible multielectrode arrays (MEAs) are developed that can measure both DA concentrations and electrophysiology chronically. The dual functionality is enabled by conducting polymer PEDOT doped with acid-functionalized carbon nanotubes (CNT).

Batch Fabrication of Microelectrode Arrays with Glassy Carbon Microelectrodes and Interconnections for Neurochemical Sensing: Promises and Challenges.

Flexible multielectrode arrays with glassy carbon (GC) electrodes and metal interconnection ( MEAs) have shown promising performance in multi-channel neurochemical sensing. A primary challenge faced by MEAs fabrication is the adhesion of the metal traces with the GC electrodes, as prolonged electrical and mechanical stimulation can lead to adhesion failure. Previous devices with GC electrodes and interconnects made of a homogeneous material ( GC) demonstrated exceptional electrochemical stability but required miniaturization for enhanced tissue integration and chronic electrochemical sensing.

Sanguinarine Attenuates Lung Cancer Progression via Oxidative Stress-induced Cell Apoptosis.

Background: Lung cancer (LC) incidence is rising globally and is reflected as a leading cause of cancer-associated deaths. Lung cancer leads to multistage carcinogenesis with gradually increasing genetic and epigenetic changes.

Aims: Sanguinarine (sang) mediated the anticancer effect in LCC lines by involving the stimulation of reactive oxygen species (ROS), impeding Bcl2, and enhancing Bax and other apoptosis-associated protein Caspase-3, -9, and -PARP, subsequently inhibiting the LC invasion and migration.

Addressing Vaccine Hesitancy: A Nursing Perspective.

Purpose: Vaccination is one of the most successful and cost-effective health promotion interventions, preventing millions of deaths per year. Vaccine hesitancy (VH) received renewed attention in the United States when over 30 million Americans were undecided or had barriers to receiving the COVID-19 vaccine. The purpose is to examine the literature regarding vaccine hesitancy, its history and legal aspects.

The first evidence for the Higgs boson decay to a Z boson and a photon is presented, with a statistical significance of 3.4 standard deviations.

Modeling of two-stage anaerobic onsite wastewater sanitation system to predict effluent soluble chemical oxygen demand through machine learning.

The present research aims to predict effluent soluble chemical oxygen demand (SCOD) in anaerobic digestion (AD) process using machine-learning based approach. Anaerobic digestion is a highly sensitive process and depends upon several environmental and operational factors, such as temperature, flow, and load. Therefore, predicting output characteristics using modeling is important not only for process monitoring and control, but also to reduce the operating cost of the treatment plant.

Student intentions to continue with distance learning post-COVID: An empirical analysis.

The aftermath of COVID changed how students learn, mainly moving to a distance learning model. The research reported in this paper investigated the organizational and individual factors that influence the preference for continuing with distance / online learning post-COVID. Partial least squares structural equation modeling was applied to a model developed for this research, based on data from 452 students from residential universities in South Africa.

Search for Dark Photons in Rare Z Boson Decays with the ATLAS Detector.

A search for events with a dark photon produced in association with a dark Higgs boson via rare decays of the standard model Z boson is presented, using 139  fb^{-1} of sqrt[s]=13  TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider. The dark boson decays into a pair of dark photons, and at least two of the three dark photons must each decay into a pair of electrons or muons, resulting in at least two same-flavor opposite-charge lepton pairs in the final state. The data are found to be consistent with the background prediction, and upper limits are set on the dark photon's coupling to the dark Higgs boson times the kinetic mixing between the standard model photon and the dark photon, α_{D}ϵ^{2}, in the dark photon mass range of [5, 40] GeV except for the ϒ mass window [8.

Defeating Nurse Workplace Bullying Through Political Activism.

Workplace bullying is a social injustice with a detrimental impact on nurse retention, job satisfaction, self-esteem, and patient care. Nurses can engage in individual-, unit-, and policy-level activities aimed at promoting a healthier work environment. In the public sphere, political activism by nurses to promote the anti-bullying Healthy Workplace Bill can help improve the safety of healthcare work settings.

Integrated approaches to prevent exposure risks related to latex-derived products.

Natural rubber latex is a widely used industrial raw material to produce many consumer and commercial products. Chronic exposures to latex allergenic proteins residual in the finished products can promote hypersensitive immune responses, which affects millions of workers and the general public worldwide. Research has shown the average prevalence of latex allergy worldwide remains approximately 10% among healthcare workers, 7% among susceptible patients, and 4% among general population.

Observation of Single-Top-Quark Production in Association with a Photon Using the ATLAS Detector.
