Global longitudinal strain is associated with better outcomes in transcatheter aortic valve replacement.

Background: Parameters that mark the timing of left ventricular (LV) reverse remodeling following transcatheter aortic valve replacement (TAVR) are incompletely defined. This study aims to identify the dynamics of LV strain derived from speckle tracking echocardiography in a cohort of patients with severe aortic stenosis (AS) who underwent TAVR and its correlation with postprocedural outcomes.

Methods: We selected 150 consecutive patients (82 ± 4 years old, STS score 6.

Treatment Patterns of Lipid-Lowering Therapy in Patients with Coronary Artery Disease Aged Above and Below 75 Years: A Retrospective Cross-Sectional Study of 1500 Patients in a Tertiary Care Referral Center in Germany.

Introduction: Lipid-lowering therapy of elderly patients with coronary artery disease (CAD) inherits a medical challenge, as these patients experience a higher absolute risk reduction but may be more prone to side effects. We aimed to evaluate the treatment patterns in lipid-lowering therapy, comparing CAD patients above versus below 75 years of age.

Methods: We retrospectively included patients with known CAD admitted to the West German Heart and Vascular Center.

CYP17 gene polymorphic sequence variation is associated with hyperandrogenism in Kashmiri women with polycystic ovarian syndrome.

Objective: Polycystic ovarian syndrome is a complex reproductive as well as endocrinological disorder characterized by anovulatory dysfunction, androgen excess and polycystic ovarian morphology. Hyperandrogenism is regarded as a cardinal feature of the disease. It is believed that the excess androgens are produced due to abnormality in steroid biosynthesis pathway wherein cytochrome P450, 17α-hydroxylase (CYP17) plays an imperative role.

Diel- and temperature-driven variation of leaf dark respiration rates and metabolite levels in rice.

Leaf respiration in the dark (R ) is often measured at a single time during the day, with hot-acclimation lowering R at a common measuring temperature. However, it is unclear whether the diel cycle influences the extent of thermal acclimation of R , or how temperature and time of day interact to influence respiratory metabolites. To examine these issues, we grew rice under 25°C : 20°C, 30°C : 25°C and 40°C : 35°C day : night cycles, measuring R and changes in metabolites at five time points spanning a single 24-h period.

Salivary proteome signatures in the early and middle stages of human pregnancy with term birth outcome.

The establishment and maintenance of pregnancy in humans proceed through a continuous change of biochemical and biophysical processes. It requires a constant interaction between the fetus and the maternal system. The present prospective study aims to elucidate changes in salivary proteome from the early to middle stages of term pregnancy, and establishing an expressional trajectory for modulated proteins.

Putative serum protein biomarkers for epsilon toxin exposure in mouse model using LC-MS/MS analysis.

Epsilon toxin (ETX), produced by Clostridium perfringens Type B or type D strains, is a potential biological and toxin warfare (BTW) agent, largely for its very high toxicity. The toxin is implicated in several animal diseases. Using LC-MS/MS analysis, we report here elucidation of putative serum maker proteins for ETX exposure with an objective of the early diagnosis of intoxication.

AT-rich Interaction Domain 1A Gene Variations: Genetic Associations and Susceptibility to Gastric Cancer Risk.

AT-rich interaction domain containing protein 1A (ARID1A), has recently emerged as a novel class of gene which acts as a potent tumor suppressor in numerous types of cancers such as Gastric, Breast, Ovarian, Colorectal, Lung cancers. ARID1A is involved in the regulation of various cellular processes such as proliferation, differentiation and DNA repair, yet its association with the susceptibility of cancer remains unknown. Here, we aimed to analyse the association of the ARID1A variants (Pro912Thr, Gln944Lys and Gln920Ter) with the risk of Gastric cancer (GC) in Kashmiri population.

A systematic review on the safety of Ramadan fasting in high-risk patients with Diabetes.

Introduction: Fasting the holy month of Ramadan is passionately practiced by all Muslim population around the world. Patients with diabetes are generally considered to have a higher risk of fasting. The current international guidelines have risk-stratified the patients with diabetes and other comorbidities to different categories, and the decision of fasting or not is made based on this categorization.

Acute Respiratory Events and Dosimetry of Total Body Irradiation Patients Using In Vivo Lung Dose Monitoring and Custom Lung Block Adaptation.

Purpose: Most myeloablative regimens before stem cell transplant involved total body irradiation (TBI). Pulmonary complications from TBI contribute to treatment-related mortality and toxicity. We report the rate of acute respiratory complications after TBI at our institution.

Impact of Bioprosthetic Choice on Mortality After Transfemoral Transcatheter Aortic Valve Implantation in Patients With Reduced Versus Preserved Left-Ventricular Ejection Fraction.

The outcome of transfemoral transcatheter aortic valve implantation (TF-TAVI) with a self-expanding (SEP) versus a balloon-expandable prosthesis (BEP) in patients with a reduced ejection fraction (rEF, ≤40%) has not been previously investigated. Patients with rEF have an increased risk of death after TF-TAVI compared to patients with a preserved ejection fraction (pEF), and prosthesis choice might influence the outcome of these patients. We, therefore, sought to compare all-cause mortality of patients with rEF using a SEP versus a BEP.

Structure of the processive human Pol δ holoenzyme.

In eukaryotes, DNA polymerase δ (Pol δ) bound to the proliferating cell nuclear antigen (PCNA) replicates the lagging strand and cooperates with flap endonuclease 1 (FEN1) to process the Okazaki fragments for their ligation. We present the high-resolution cryo-EM structure of the human processive Pol δ-DNA-PCNA complex in the absence and presence of FEN1. Pol δ is anchored to one of the three PCNA monomers through the C-terminal domain of the catalytic subunit.

Anticancer evaluation of a manganese complex on HeLa and MCF-7 cancer cells: design, deterministic solvothermal synthesis approach, Hirshfeld analysis, DNA binding, intracellular reactive oxygen species production, electrochemical characterization and density functional theory.

Herein, a deterministic solvothermal strategy was employed to synthesize an efficient anticancer agent '-dichlorobis(1,10-phenanthroline)manganese(II)' (Mn(phen)Cl). A single-crystal X-ray diffraction analysis revealed that Mn(phen)Cl crystallizes in a triclinic system with the space group . Cyclic voltammetric studies of Mn(phen)Cl indicated that the electrode process occurs only due to complex formation and has a diffusion-controlled mechanism.

Acute PFOA exposure promotes epigenomic alterations in mouse kidney tissues.

Perfluorooctanoic acid (PFOA), a manufactured perfluorochemical is a common surfactant and environmental pollutant found in various consumer products and water sources. Epidemiological studies have demonstrated its association with kidney dysfunction. However, the mechanisms that trigger kidney dysfunction following PFOA exposure is a gap in the field.

Down-Regulation of Flagellar, Fimbriae, and Pili Proteins in Carbapenem-Resistant (NDM-4) Clinical Isolates: A Novel Linkage to Drug Resistance.

The emergence and spread of carbapenem-resistant infections have worsened the current situation worldwide, in which totally drug-resistant strains (bad bugs) are becoming increasingly prominent. Bacterial biofilms enable bacteria to tolerate higher doses of antibiotics and other stresses, which may lead to the drug resistance. In the present study, we performed proteomics on the carbapenem-resistant NDM-4-producing e clinical isolate under meropenem stress.

Objective: The purpose of this study was to describe the incidence and risk factors for readmission for treatment failure after nonoperative management of acute diverticulitis using a large national database.

Design: This was a retrospective cohort study.

Platelet-derived growth factor-AB improves scar mechanics and vascularity after myocardial infarction.

Therapies that target scar formation after myocardial infarction (MI) could prevent ensuing heart failure or death from ventricular arrhythmias. We have previously shown that recombinant human platelet-derived growth factor-AB (rhPDGF-AB) improves cardiac function in a rodent model of MI. To progress clinical translation, we evaluated rhPDGF-AB treatment in a clinically relevant porcine model of myocardial ischemia-reperfusion.

Molecular and physiological responses during thermal acclimation of leaf photosynthesis and respiration in rice.

To further our understanding of how sustained changes in temperature affect the carbon economy of rice (Oryza sativa), hydroponically grown plants of the IR64 cultivar were developed at 30°C/25°C (day/night) before being shifted to 25/20°C or 40/35°C. Leaf messenger RNA and protein abundance, sugar and starch concentrations, and gas-exchange and elongation rates were measured on preexisting leaves (PE) already developed at 30/25°C or leaves newly developed (ND) subsequent to temperature transfer. Following a shift in growth temperature, there was a transient adjustment in metabolic gene transcript abundance of PE leaves before homoeostasis was reached within 24 hr, aligning with R (leaf dark respiratory CO release) and A (net CO assimilation) changes.
