Antiviral Mx proteins have an ancient origin and widespread distribution among eukaryotes.

Mx proteins, first identified in mammals, encode potent antiviral activity against a wide range of viruses. Mx proteins arose within the Dynamin superfamily of proteins (DSP), which mediate critical cellular processes, such as endocytosis and mitochondrial, plastid, and peroxisomal dynamics. Despite their crucial role, the evolutionary origins of Mx proteins are poorly understood.

Efficacy and safety of ivermectin-albendazole combination versus ivermectin or albendazole monotherapy in soil-transmitted helminthiasis: A systematic review and meta-analysis.

Background: Soil-transmitted helminthiasis remains a daunting challenge to global health, exerting its greatest toll on resource-limited regions of the world. A dual drug approach using the co-administration of ivermectin and albendazole has shown promising results in comparison to the traditional monotherapy strategy. In light of this, a systematic review and meta-analysis of randomized controlled trials was conducted.

Outcomes after index cholecystectomy: a UK longitudinal multi-centre cohort Study.

Purpose: International guidelines for management of acute biliary pathology recommend emergency cholecystectomy (EmC), citing improved outcomes compared to elective cholecystectomy (ElC) based on trials which may not reflect the capacity constraints in clinical practice, nor selection based on multiple prior attendances with emergency biliary pathology or attendances following a decision for ElC. We therefore conducted a longitudinal retrospective study evaluating all attendances with biliary pathology prior to cholecystectomy with the aim of assessing whether EmC is justified in this context.

Methods: Data was collected on patients undergoing cholecystectomy between 2016 and 2021 at four centres.

Evaluating the necessity of postoperative day 1 labs following laparoscopic radical nephrectomy (LRN).

Background: Standard postoperative care following laparoscopic radical nephrectomy (LRN) typically includes routine blood tests. Recent studies have assessed the safety of omitting routine postoperative labs in minimally invasive surgeries to reduce hospital costs. Our primary objective was to evaluate if routine postoperative day 1 (POD1) labs were necessary following LRN.

Comparative efficacy, safety, and oncological outcomes of percutaneous thermal and chemical ablation modalities for recurrent metastatic cervical lymphadenopathy from thyroid cancer.

Background: Thermal and chemical ablation techniques may consolidate recurrent metastatic cervical lymph nodes as alternatives to repeat neck dissection in thyroid cancer patients. This meta-analysis aims to compare the efficacy and safety across modalities.

Methods: Four databases were searched for studies on radiofrequency (RFA), microwave (MWA), laser (LA), and ethanol ablation (EA) treating metastatic cervical nodes from thyroid cancer.

Emerging paradigm: Molecularly targeted therapy with Dabrafenib and Trametinib in recurring pediatric gliomas with BRAF mutations: A narrative review.

Gliomas are tumors arising in the central nervous system, frequently associated with Class I mutations and BRAF fusions. These mutations are adverse prognostic factors in juvenile gliomas, leading to high rates of recurrence and poor response to current treatments. The blood-brain barrier and the heterogeneity of gliomas complicate the development of a single treatment strategy for all cases.

Vibrio vulnificus Bacteremia With Compartment Syndrome: A Case Report and Characterization of the Isolate.

is a Gram-negative, curved, rod-shaped organism that can cause sepsis due to either gastroenteritis when ingested (usually via raw oysters) or skin infections when introduced into cuts or abrasions. Found in estuarine waters (coastal waters where fresh water from streams mixes with salt water from the ocean resulting in water of intermediate salinity (i.e.

Understanding childhood obesity in Pakistan: exploring the knowledge, attitudes, practices of mothers, and influential factors. A cross-sectional study.

Background: Childhood obesity is a significant public health issue with far-reaching implications. The World Health Organization reported that in 2020, around 38 million children under five were overweight or obese globally, and in 2016, 340 million children and adolescents aged 5-19 were affected. In Pakistan, the situation is alarming; 66.

Cross-sectional assessment of perception and attitude of pharmacy students towards pharmaceutical promotion: a study from developing country, Pakistan.

Background: The pharmaceutical promotion is "all informational and persuasive activities by manufacturers and distributors, the effect of which is to induce the prescription, supply, purchase and/or use of medicinal drugs. These promotional activities affect the dispensing behavior of physicians and pharmacists and influence begins from educational institutes.

Objective: Our study's main aim was to evaluate opinion and attitude of pharmacy students towards pharmaceutical promotion.

A novel PhoPQ-potentiated mechanism of colistin resistance impairs membrane integrity in .

Polymicrobial communities are often recalcitrant to antibiotic treatment because interactions between different microbes can dramatically alter their responses and susceptibility to antimicrobials. However, the mechanisms of evolving antimicrobial resistance in such polymicrobial environments are poorly understood. We previously reported that Mg depletion caused by the fungus can enable to acquire significant resistance to colistin, a last-resort antibiotic targeting bacterial membrane.

Heterozygous and generalist MxA super-restrictors overcome breadth-specificity tradeoffs in antiviral restriction.

Antiviral restriction factors such as MxA (myxovirus resistance protein A) inhibit a broad range of viruses. However, they face the challenge of maintaining this breadth as viruses evolve to escape their defense. Viral escape drives restriction factors to evolve rapidly, selecting for amino acid changes at their virus-binding interfaces to regain defense.

Failure to Rescue After Resection of Perhilar Cholangiocarcinoma in an International Multicenter Cohort.

Background: Failure to rescue (FTR) is defined as the inability to prevent death after the development of a complication. FTR is a parameter in evaluating multidisciplinary postoperative complication management. The aim of this study was to evaluate FTR rates after major liver resection for perihilar cholangiocarcinoma (pCCA) and analyze factors associated with FTR.

Recognition of phylogenetically diverse pathogens through enzymatically amplified recruitment of RNF213.

Innate immunity senses microbial ligands known as pathogen-associated molecular patterns (PAMPs). Except for nucleic acids, PAMPs are exceedingly taxa-specific, thus enabling pattern recognition receptors to detect cognate pathogens while ignoring others. How the E3 ubiquitin ligase RNF213 can respond to phylogenetically distant pathogens, including Gram-negative Salmonella, Gram-positive Listeria, and eukaryotic Toxoplasma, remains unknown.

IRS2 Signaling Protects Against Stress-Induced Arrhythmia by Maintaining Ca Homeostasis.

Background: The docking protein IRS2 (insulin receptor substrate protein-2) is an important mediator of insulin signaling and may also regulate other signaling pathways. Murine hearts with cardiomyocyte-restricted deletion of (cIRS2-KO) are more susceptible to pressure overload-induced cardiac dysfunction, implying a critical protective role of IRS2 in cardiac adaptation to stress through mechanisms that are not fully understood. There is limited evidence regarding the function of IRS2 beyond metabolic homeostasis regulation, particularly in the context of cardiac disease.

Conformational Switching of a Nano-Size Urea-Bridged Zn(II)Porphyrin Dimer by External Stimuli.

For the first time, explicit stabilization of all the three conformers, viz. (cis,cis), (cis,trans) and (trans,trans), of a 'nano-sized' highly-flexible urea-bridged Zn(II)porphyrin dimer have been achieved via careful manipulations of external stimuli such as solvent dielectrics, temperature, anionic interactions, axial ligation and surface-induced stabilization. The conformers differ widely in their structures, chemical and photophysical properties and thus have vast potential applicability.

A conserved opal termination codon optimizes a temperature-dependent tradeoff between protein production and processing in alphaviruses.

Alphaviruses are enveloped, single-stranded, positive-sense RNA viruses that often require transmission between arthropod and vertebrate hosts for their sustained propagation. Most alphaviruses encode an opal (UGA) termination codon in nonstructural protein 3 (nsP3) upstream of the viral polymerase, nsP4. The selective constraints underlying the conservation of the opal codon are poorly understood.
