Solving the maximum cut problem using Harris Hawk Optimization algorithm.

The objective of the max-cut problem is to cut any graph in such a way that the total weight of the edges that are cut off is maximum in both subsets of vertices that are divided due to the cut of the edges. Although it is an elementary graph partitioning problem, it is one of the most challenging combinatorial optimization-based problems, and tons of application areas make this problem highly admissible. Due to its admissibility, the problem is solved using the Harris Hawk Optimization algorithm (HHO).

The Effect of Online Group Education on Promoting Knowledge, Motivation, Self-Efficacy, Self-Care Behaviors and Preventing Uncontrolled Blood Pressure in Hypertensive Patients: A Quasi-Experiment Study.

Introduction: Hypertensive patients may lack time to visit clinics and attend educational sessions, resulting in poor blood pressure control. Uncontrolled blood pressure in people with hypertension can increase the risk of heart disease and stroke.

Objective: The specific purpose of this study was to determine the effect of online group education on knowledge, motivation, self-efficacy, self-care behavior, and blood pressure control of hypertensive patients.

Statistical phase alignment of edge spread function for modulation transfer function measurement on computed tomography images.

Purpose: This study aimed to develop a statistical approach for edge spread function (ESF) phase alignment to improve the accuracy of modulation transfer function (MTF) measurements at the edges of computed tomography (CT) images.

Methods: A statistical approach to ESF phase alignment was initiated by collecting ESF samples with poor phase alignment. One ESF sample was selected as the reference ESF and the other as the treated ESF.

Disease-associated B cells and immune endotypes shape adaptive immune responses to SARS-CoV-2 mRNA vaccination in human SLE.

Severe acute respiratory syndrome coronavirus 2 mRNA vaccination has reduced effectiveness in certain immunocompromised individuals. However, the cellular mechanisms underlying these defects, as well as the contribution of disease-induced cellular abnormalities, remain largely unexplored. In this study, we conducted a comprehensive serological and cellular analysis of patients with autoimmune systemic lupus erythematosus (SLE) who received the Wuhan-Hu-1 monovalent mRNA coronavirus disease 2019 vaccine.

Anesthetic Management of Intracardiac Migration of Medical Devices.

The use of endovascular, percutaneous interventions to treat cardiac, arterial, and venous pathologies is becoming increasingly common in medical practice. While endovascular device placement typically carries a low risk, device migration remains a persistent problem with these procedures for which anesthesia providers must have a high index of suspicion. Anesthesia providers should be aware of the wide range of indications for such devices, potential migration locations, and hemodynamic consequences of both the inciting pathology and device migration so they can safely care for patients in these settings.

Ending AIDS as a public health threat: the imperative for clear messaging on U=U, viral suppression, and zero risk.

To end AIDS as a public health threat by 2030, we must leverage both the impactful message of U=U (undetectable equals untransmittable) and viral suppression to improve the wellbeing of individuals living with HIV, increase engagement with HIV services, and reduce barriers such as stigma, discrimination, and criminalisation. This message requires clear and unambiguous evidence-based narratives that emphasise the message that there is zero risk of sexual transmission when an undetectable viral load is maintained and negligible risk when viral suppression (as defined by 200-1000 copies per mL) is maintained. Dissemination of this information to individuals living with or affected by HIV, health-care workers, communities, the general public, and policy makers will increase awareness and credibility of this message and challenge deep-seated misperceptions.

A Phase 1a/1b Study of Fostroxacitabine Bralpamide (Fostrox) Monotherapy in Hepatocellular Carcinoma and Solid Tumor Liver Metastases.

Purpose: To evaluate safety, preliminary efficacy, pharmacokinetics, and pharmacodynamics, of fostroxacitabine bralpamide (fostrox, MIV-818), a novel oral troxacitabine nucleotide prodrug designed to direct exposure to the liver, while minimizing systemic toxicity.

Patients And Methods: Fostrox monotherapy was administered in an open-label, single-arm, first-in-human, phase 1a/1b study, in patients with hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma, or solid tumor liver metastases. The first part (1a) consisted of intra/inter-patient escalating doses (3 mg to 70 mg) QD for up to 5 days, and the second part (1b), doses of 40 mg QD for 5 days, in 21-day cycles.

Thrombogenic Risk Assessment of Transcatheter Prosthetic Heart Valves Using a Fluid-Structure Interaction Approach.

Background And Objective: Prosthetic heart valve interventions such as TAVR have surged over the past decade, but the associated complication of long-term, life-threatening thrombotic events continues to undermine patient outcomes. Thus, improving thrombogenic risk analysis of TAVR devices is crucial. In vitro studies for thrombogenicity are typically difficult to perform.

Polyamines and hydrogen peroxide: Allies in plant resilience against abiotic stress.

The increasing prevalence and severity of abiotic stresses on plants due to climate change is among the crucial issues of decreased crop productivity worldwide. These stresses affect crop productivity and pose a challenge to food security. Polyamines (Pas) and hydrogen peroxide (H₂O₂) could play a vital role to minimize the impact of several abiotic stresses on the plants.

Therapeutic plasma exchange in expanded dengue patients having acute liver failure: A case series.

Expanded dengue syndrome is a severe form of dengue fever that can cause acute liver failure and patients with this condition have a high mortality rate. This is because it can cause a cytokine storm, Unfortunately, standard treatments are often ineffective. Therapeutic plasma exchange is a procedure that removes cytokines and improves the patient's condition.

Quantitative analysis of loxoprofen sodium loaded microspheres comprising pectin and its thiolated conjugates: evaluation of their sustained release behavior.

Continuous use of oral NSAIDs can damage mucosal membrane, which results in decreased bioavailability and non-compliance with the therapy. But the use of sustained release drug delivery systems might offer a solution. Objective was to synthesize mucoadhesive SR microspheres by using different combinations of pectin (PEC) and its thiolated derivative (T-PEC3100) for improved loxoprofen (LS) permeation.

Cellulose nanofibers of oil palm fronds as a filler in nanocomposite coating for corrosion protection of copper.

Cellulose nanofibers (CNF) create a physical barrier preventing contact with corrosive substances and improving corrosion prevention. Oil palm fronds (OPF), the primary source of underused biomass waste from plantations, were processed into CNF. The OPF-CNF, mixed with hydroxyethyl cellulose as the matrix, forms a nanocomposite.

Background: Calcific tendonitis is a painful shoulder disorder characterized by calcium deposits (CDs) in the rotator cuff tendon. This systematic review and meta-analysis examined the most efficient surgical procedure for calcific tendonitis. This includes the comparison between the three main surgical techniques: CD removal, CD removal with subacromial decompression (SAD) and CD removal with tendon repair with respect to functional outcomes and pain control scores.

Targeting Myeloid Differentiation Primary Response Protein 88 (MyD88) and Galectin-3 to Develop Broad-Spectrum Host-Mediated Therapeutics against SARS-CoV-2.

Nearly six million people worldwide have died from the coronavirus disease (COVID-19) outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Although COVID-19 vaccines are largely successful in reducing the severity of the disease and deaths, the decline in vaccine-induced immunity over time and the continuing emergence of new viral variants or mutations underscore the need for an alternative strategy for developing broad-spectrum host-mediated therapeutics against SARS-CoV-2. A key feature of severe COVID-19 is dysregulated innate immune signaling, culminating in a high expression of numerous pro-inflammatory cytokines and chemokines and a lack of antiviral interferons (IFNs), particularly type I (alpha and beta) and type III (lambda).

Evaluation of radiation protection effectivity in a cardiac angiography room using visualized scattered radiation distribution.

In this study, we devised a radiation protection tool specifically designed for healthcare professionals and students engaged in cardiac catheterization to easily monitor and evaluate scattered radiation distribution across diverse C-arm angles and arbitrary physician associated staff positions-scrub nurse and technologist positions. In this study, scattered radiation distributions in an angiography room were calculated using the Monte Carlo simulation of particle and heavy ion transport code system (PHITS) code. Four visualizations were performed under different C-arm angles with and without radiation protection: (1) a dose profile, (2) a 2D cross-section, (3) a 3D scattered radiation distribution, and (4) a 4D scattered radiation distribution.
