RNS

The compelling evidence that higher RN to resident ratios improve health outcomes in nursing homes underscores the necessity of implementing evidence-based RN nursing home staffing standards. However, there are other dimensions to RN staffing in nursing homes beyond the numbers or hours per resident day (HPRD) that influence the quality of care. Without attending to a broader focus on nurse staffing, the benefits of increased RN staffing levels will not be achieved. This article outlines how RN HPRD can be maximized by magnifying the RN's scope of practice and attending to how nursing care is organized and delivered in nursing homes using a nursing practice model framework...

NADPH-oxidase (NOX) is a multi-subunit enzyme complex. The upregulation of NOX causes massive production of superoxide (O2 ¯ ), which avidly reacts with nitric oxide (NO) and increases cellular reactive oxygen/nitrogen species (ROS/RNS). Increased ROS/RNS plays pivotal role in the sporadic Alzheimer's disease (sAD) development and brain damage following impaired insulin signaling. Hence, this study aimed to examine early-time course of changes in NOX and NOS expression, and apoptotic proteins in the rats hippocampi following insulin signaling impairment [induced by STZ injection; intraperitoneal (IP) or in cerebral ventricles (ICV)]...

Vascular diseases seriously threaten human life and health. Exogenous delivery of nitric oxide (NO) represents an effective approach for maintaining vascular homeostasis during pathological events. However, the overproduction of reactive oxygen species (ROS) at vascular injury sites would react with NO to produce damaging peroxynitrite (ONOO- ) species and limit the therapeutic effect of NO. Hence, we design a ROS-responsive NO nanomedicine (t-PBA&NO NP) with ROS scavenging ability to solve the dilemma of NO-based therapy...

Overproduction of reactive nitrogen and oxygen species (RNS and ROS) has been linked to the pathogenesis of diabetes, hypertension, hyperlipidemia, stroke, angina, and other cardiovascular diseases. These species are produced in part by the mitochondrial respiratory chain, NADPH oxidase, and xanthine oxidase. RNS and ROS both contribute to oxidative stress, which is necessary for the development of cardiovascular disorders. In addition to ROS species like hydroxyl ion, hydrogen peroxide, and superoxide anion, RNS species like nitric oxide, peroxynitrous acid, peroxynitrite, and nitrogen dioxide radicals have also been linked to a number of cardiovascular conditions...

A novel trimethyltin(IV) complex ( Me3 SnL ), derived from 3-(4-methyl-2-oxoquinolin-1(2H)-yl)propanoate ligand, has been synthesized and characterized by elemental microanalysis, UV/Vis spectrophotometry, FT-IR and multinuclear (1 H, 13 C and 119 Sn) NMR spectroscopies. Furthermore, the structure of the ligand precursor HL was solved using SC-XRD (single-crystal X-ray diffraction). The prediction of UV/Vis and NMR spectra by quantum-chemical methods was performed and compared to experimental findings. The protein binding affinity of Me3 SnL towards BSA was determined by spectrofluorometric titration and subsequent molecular docking simulations...

Alcohol use disorder (AUD) is a major component in the etiology of cognitive decline and dementia. Underlying mechanisms by which long-term alcohol abuse causes cognitive dysfunction include excessive oxidative stress and inflammation in the brain, activated by increased reactive oxygen/nitrogen species (ROS/RNS), advanced glycation end-products (AGEs) and high-mobility group box 1 protein (HMGB1). In a pilot study, we examine the potential clinical value of circulating biomarkers of oxidative stress including ROS/RNS, HMGB1, the soluble receptor for AGE (sRAGE), the brain biomarker of aging apolipoprotein D (ApoD), and the antioxidant regulator nuclear factor erythroid 2-related factor 2 (NRF2) as predictive indices for cognitive impairment (CI) in abstinent patients with AUD ( n = 25) compared to patients with established Alzheimer's disease (AD, n = 26) and control subjects ( n = 25)...

Xylella fastidiosa ( Xf ) is a global bacterial threat for a diversity of plants, including olive trees. However, current understanding of host responses upon Xf -infection is limited to allow early disease prediction, diagnosis, and sustainable strategies for breeding on plant tolerance. Recently, we identified a ma jor c omplex t rait for e arly d e novo programming, named CoV-MAC-TED , by comparing early transcriptome data during plant cell survival with SARS-CoV-2-infected human cells. This trait linked ROS/RNS balancing during first hours of stress perception with increased aerobic fermentation connected to alpha-tubulin-based cell restructuration and control of cell cycle progression...

BACKGROUND: Transferring residents from nursing homes (NHs) to emergency care facilities (ECFs) is often questioned as many are terminally ill and have access to onsite care. While some NH to ECF transfers have merit, avoiding other transfers may benefit residents and reduce healthcare system costs and provider burden. Despite many years of research in this area, differentiating warranted (i.e., appropriate) from unwarranted NH to ECF transfers remains challenging. In this article, we report consensus on warranted and unwarranted NH to ECF transfers scenarios...

BACKGROUND: A valid and reliable tool is crucial for municipal registered nurses (RNs) to make quick decisions in older adults who show rapid signs of health deterioration. The aim of this study was to investigate the psychometric properties of the Decision Support System (DSS) among older adults in the municipal healthcare system. METHODS: Firstly, we utilized the Rasch dichotomous model to analyze the DSS assessments (n=281) that were collected from municipal RNs working with older adults in the municipal healthcare system...

Clinical treatment of advanced hepatocellular carcinoma (HCC) remains a significant challenge. The use of RRx-001 with the function of downregulating the expression of innate immune checkpoint molecule CD47 provides a powerful means for treating advanced HCC containing a substantial proportion of immunosuppressive macrophages. We reported herein engineering of a previously optimized DOX-delivery nanoplatform based on sodium alginate to further co-deliver RRx-001 (BEA-D@R) for efficient immunotherapy of advanced HCC...

Helicobacter pylori-associated stomach infection is a leading cause of gastric ulcer and related cancer. H. pylori modulates the functions of infiltrated immune cells to survive the killing by reactive oxygen and nitrogen species (ROS and RNS) produced by these cells. Uncontrolled immune responses further produce excess ROS and RNS which lead to mucosal damage. The persistent oxidative stress is a major cause of gastric cancer. H. pylori regulates nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOXs), nitric oxide synthase 2 (NOS2), and polyamines to control ROS and RNS release through lesser-known mechanisms...

OBJECTIVES: Responsive neurostimulation (RNS) is an established therapy for drug-resistant epilepsy that delivers direct electrical brain stimulation in response to detected epileptiform activity. However, despite an overall reduction in seizure frequency, clinical outcomes are variable, and few patients become seizure-free. The aim of this retrospective study was to evaluate aperiodic electrophysiological activity, associated with excitation/inhibition balance, as a novel electrographic biomarker of seizure reduction to aid early prognostication of the clinical response to RNS...

The innate immune response represents the first-line of defense against invading pathogens. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) have been implicated in various aspects of innate immune function, which involves respiratory bursts and inflammasome activation. These reactive species widely distributed within the cellular environment are short-lived intermediates that play a vital role in cellular signaling and proliferation and are likely to depend on their subcellular site of formation...

Lennox Gastaut Syndrome (LGS) is characterized by drug-resistant epilepsy that typically leads to decreased quality of life and deleterious neurodevelopmental comorbidities from medically refractory seizures. In recent years there has been a dramatic increase in the development and availability of novel treatment strategies for Lennox Gastaut Syndrome patient to improve seizure. Recent advances in neuromodulation and minimally invasive magnetic resonance guided laser interstitial thermal therapy (MRgLITT) have paved the way for new treatments strategies including deep brain stimulation (DBS), responsive neurostimulation (RNS), and MRgLITT corpus callosum ablation...

Because of increasing RN turnover rates on a neuroscience unit in a large teaching hospital, unit nurse leaders created a staff retention quality improvement initiative. The initiative offered a structured pathway for professional development milestones in a nurse's 1st 18 months of employment. As a consequence of their work, the unit experienced an 82% decrease in the number of RNs who left their job on the unit in the 1st year of implementation.

Recognizing the positive impact of clinical data outcomes and patient care experiences, coupled with the growing preference for advanced practice RNs among patients, it is imperative that nurse leaders propel legislative reforms and infrastructure support from health systems. This strategic approach is crucial for maximizing the potential of nurses in improving patient care experience and outcomes, as well as increasing accessibility to healthcare in every community.

Non-thermal atmospheric pressure plasma (NTP), an ionized gas containing electrons, ions, radicals, and photons, has various biological effects, including wound healing and anticancer effects. Plasma-activated medium (PAM), which is prepared by irradiating medium with NTP, preferentially kills cancer cells. Large amounts of reactive oxygen species (ROS) and reactive nitrogen species (RNS) included in PAM are closely related to its anticancer effects. The precise mechanism of PAM-induced cytotoxicity is not fully understood; however, PAM exposure has been reported to reduce cellular energy metabolism...
