The largest continental shelf Oxygen Minimum Zone (OMZ) in the world is formed along the Indian western shelf in the eastern Arabian Sea during the Southwest Monsoon [(SWM); June-September], which is a natural pollution event associated with the coastal upwelling. This study examines the composition, abundance, and distribution of copepods during the Northeast Monsoon [(NEM); November to February] and SWM in 50 m depth zones along the Indian western shelf in the eastern Arabian Sea. The NEM was characterised by warm, stratified, and low-salinity waters in the southeast Arabian Sea and cold, high-salinity, and well-mixed waters in the northeastern Arabian Sea...

BACKGROUND: People with multiple sclerosis (pwMS) on anti-CD20 therapies (aCD20) and fingolimod have shown inadequate humoral responses to COVID-19 vaccines. OBJECTIVE: The objective of the study was to pilot larger studies by demonstrating the safety and comparing the immunogenicity of different types of third doses in seronegative pwMS after two doses of BBIBP-CorV inactivated vaccine. METHODS: In December 2021, subject to receiving their third dose, being COVID-19-naiive, and receiving no corticosteroid within two months, we measured the level of anti-SARS-CoV-2-Spike IgG in pwMS seronegative after two shots of BBIBP-CorV inactivated vaccine...

Large amounts of TENORM waste (produced water, scale, and sludge) are created in oilfields around the world, presenting radiological risks to employees, the public, and the environment since activity concentrations of radioactive substances were above the exemption levels accredited by several authorities. Using the activity concentration of the radium-isotopes (226 Ra and 228 Ra) in the waste, we determined the 'fingerprint' as a radiochemical signature and some relevant 'radiological hazard parameters' in this review...

About 10 years ago, a protein family was shown for the first time to contain allergenic members, gibberellin-regulated protein (GRP). The first reported member was from peach, Pru p 7. One can hypothesize that it was not detected before because its physicochemical characteristics overlap with those of lipid transfer protein (LTP), a well-known allergen, or because the exposure to GRP increased due to an increase in the gibberellin phythormone level in plant food, either exogenous or endogenous. Like LTPs, GRPs are small cationic proteins with disulfide bridges, are resistant to heat and proteolytic cleavage, and are involved in the defense of the plant...

Background and Objectives : Endothelial microparticles (EMP) particularly CD31+ /42- /AV+ , CD144+ /AV+ and CD62e+ /AV+ have been reported as having increased in cardiovascular-related diseases, making them potential biomarkers for endothelial dysfunction. This study aimed to compare these EMPs in patients with hypercholesterolemia and healthy controls and to correlate their levels with endothelium-dependent vasodilation (EDV) assessed via pulse wave analysis (PWA); an established method of assessing endothelial function...

Introduction: Stiff knees are defined as those with an arc of motion < 50°. They pose a considerable surgical challenge to the operating surgeon. Based on our experience to deal with these complex cases, we have developed a working classification that outlines a flowchart to manage the stiff/ankylosed knees. Materials and Methods: It was a retrospective study conducted in our department. Out of 570 TKA performed in last 5 years, 57 had stiffness and four had bony ankyloses (total 61 knees)...

Despite widespread and its local available as a naturalized hedge and shade plant, the potential of Trichilia emetica was not utilized in soap making by the majority of local community in various parts of Dodoma, Tanzania. This study aimed to assess the quantity (yields) and quality (Acid Values (AVs), %Free Fatty Acids (%FFAs) and Saponification Values (SVs) of seed oil from water plant ( T. emetica ), suitable for soap making application. Solvent extraction method was used during oil extraction, where by 50gm of preheated and powdered seed materials were immersed in 250 ml of n-hexane in 1:5 (w/v) to dissolve the oil contained in the seed cake...

A 78-year-old woman had a semicircular ulcerative lesion of AV 7 cm, as detected using colonoscopy, and pathologic examination based on a biopsy showed well-differentiated adenocarcinoma. On contrast-enhanced CT of the liver, a number of nodular lesions that seemed to be liver metastases were observed. It was decided to administer chemotherapy containing mFOLFOX6 plus panitumumab. Bilateral hemorrhage of the ocular conjunctiva and eyelid edema were observed from the 4th day of chemotherapy. Edema of the lips, epidermolysis, and erythema appeared in addition to vision impairment...

An n-p type homostructural metal-free graphitic carbon nitride (g-C3 N4 ) semiconductor is designed and developed for pollutant abatement and energy storage application. The successful grafting of vibrio-like morphology-based g-C3 N4 by 2, 5-Thiophenedicarboxylic acid (TDA) molecule and the development of amide-type linkage substantiated the prosperous uniting of g-C3 N4 with organic TDA moiety is demonstrated. An extended π-conjugative TDA grafted g-C3 N4 exhibited band gap tunability with broadband optical absorbance in the visible region...

Understanding site fidelity is important in animal ecology, but evidence is lacking that this behaviour is due to an animal choosing a specific location. To discern site selection behaviour, it is necessary to consider the spatial distribution of habitats that animals can occupy within a landscape. Tracking animals and defining clear habitat boundaries, however, is often difficult. We use in situ habitat distribution data and animal movement simulations to investigate behavioural choice in site fidelity patterns...

BACKGROUND: Hemodialysis (HD) in children with a concomitant ventriculoperitoneal shunt (VPS) is rare. Registry data suggest that peritoneal dialysis with a VPS is safe, but little is known about HD in the presence of a VPS. METHODS: We performed a 10-year survey to determine the prevalence of a VPS, complications and outcome in children with a VPS on HD in 15 dialysis units from the 13 countries participating in the European Pediatric Dialysis Working Group. RESULTS: Eleven cases of HD with a VPS were reported (prevalence 1...

Atrioventricular valve regurgitation is one of the predictors of adverse outcomes after the Fontan procedure. We describe our surgical technique of GoreTex (W. L. Gore & Associates, Inc., Flagstaff, AZ, USA) bridge to repair a common atrioventricular valve in single-ventricular circulation. The repair includes a GoreTex strip that is secured to the mid-line of both superior and inferior bridging leaflets and annulus to obtain a better coaptation of the leaflets and prevent further dilatation of the annulus...

OBJECTIVE: Current guidelines suggest that arteriovenous fistula (AVF) is associated with survival advantage over arteriovenous graft (AVG). However, AVFs often require months to become functional, increasing tunneled dialysis catheter (TDC) use, which can erode the benefit of an AVF. We sought to compare survival in patients with end-stage renal disease after creation of an AVF or AVG in patients starting hemodialysis (HD) with a TDC and to identify patient populations that may benefit from preferential use of AVG over AVF...

BACKGROUND: Activation of the immune system plays a pathogenic role in the process of myocardial remodeling in patients with supraventricular arrhythmias. The intensity of this process is associated with the effectiveness of electrical cardioversion and radiofrequency catheter ablation (RFA). The aim of this study was to test the ability of the biochip microarray to detect immune parameters in patients with supraventricular arrhythmias undergoing RFA treatment. METHODS: We used a biochip-based microarray system to determine multiple immune parameters in a group of 35 patients who had undergone RFA for atrioventricular nodal reentry tachycardia (AVNRT), atrial flutter (AFL) and atrial fibrillation (AF)...

OBJECTIVE: Although radial-cephalic (RC) and brachial-cephalic (BC) fistulas are the recommended primary accesses for hemodialysis, access failure is frequently due to juxta-anastomotic stenosis (JAS). Because increased turbulence at the anastomosis may lead to JAS, we hypothesized that an acute angle at the arteriovenous anastomosis is associated with JAS, reduced fistula patency, and increased reinterventions. METHODS: Between February 2013 and September 2014, the anastomotic angle and vessel diameters were prospectively collected for all patients who underwent RC or BC fistula creation...

BACKGROUND: Discordant atrioventricular with concordant ventriculo-arterial connections is a rare cardiac defect. When isolated, the haemodynamics resemble transposition of the great arteries. In complex heart defects such as heterotaxy, haemodynamics guide the surgical approach. OBJECTIVE: To report a series of eight patients with discordant atrioventricular and concordant ventriculo-arterial connections focussing on anatomical and diagnostic difficulties, surgical management, and follow-up...

Recent studies have shown that the sensitivity of apamin-sensitive K(+) current (I KAS, mediated by apamin-sensitive small conductance calcium-activated potassium channels subunits) to intracellular Ca(2+) is increased in heart failure (HF), leading to I KAS upregulation, action potential duration shortening, early after depolarization, and recurrent spontaneous ventricular fibrillation. We hypothesized that casein kinase 2 (CK2) interacted with small conductance calcium-activated potassium channels (SK) is decreased in HF, and protein phosphatase 2A (PP2A) is increased on the opposite, upregulating the sensitivity of I KAS to intracellular Ca(2+) in HF...

INTRODUCTION: Convex spherical anamorphosis is a barrel distortion that consists of the application of a plane surface on a convex hemisphere. Applied in vascular imaging of brain arteriovenous malformations (bAVMs), this deformation may help to 'spread' the nidus and surrounding vessels (arteries/veins) and thus to differentiate the different components of bAVMs more accurately. METHODS: The imaging data from 15 patients (8 male, 7 female; 14 supratentorial bAVMs, 1 infratentorial) were used to test the algorithm...

PURPOSE: Cardiac sarcoidosis (CS) is a cause of conduction system disease (CSD). (18)F-Fluorodeoxyglucose-positron emission tomography (FDG PET) and cardiac magnetic resonance (CMR) are used for detection of CS. The relative diagnostic value of these has not been well studied. The aim was to compare these imaging modalities in this population. METHODS: We recruited steroid-naive patients with newly diagnosed CSD due to CS. All CS patients underwent both imaging studies within 12 weeks of each other...

PURPOSE: Several investigators have found that preserving the superior thyroid artery flap can considerably increase the survival rate of the sternocleidomastoid (SCM) flap. Nevertheless, they have recommended not cleaning the lymph nodes above level II for occipital artery preservation, which can leave risky metastatic lymph nodes and restrict the application of the SCM flap in patients with at least stage N1. The authors propose that preserving only the superior thyroid arteriovenous system is sufficient to ensure survival of the SCM flap and preserving the occipital artery is not necessary...
