Background: Left bundle branch area pacing (LBBAP) and endocardial resynchronization (Endo-CRT) are alternatives to biventricular pacing for cardiac resynchronization therapy (CRT).

Objective: To compare the outcomes of LBBAP versus Endo-CRT using conventional pacing leads.

Methods: Patients with heart failure (HF) undergoing CRT with LBBAP or Endo-CRT were included.

Cardiac resynchronisation therapy (CRT) reduces the risk of heart failure-related hospitalisations and all-cause mortality, as well as improving quality of life and functional status in patients with persistent heart failure symptoms despite optimal medical treatment and left bundle branch block. CRT has traditionally been delivered by implanting a lead through the coronary sinus to capture the left ventricular epicardium; however, this approach is associated with significant drawbacks, including a high rate of procedural failure, phrenic nerve stimulation, high pacing thresholds and lead dislodgement. Moreover, a significant proportion of patients fail to derive any significant benefit.

Human African trypanosomiasis (HAT) is a neglected tropical disease caused by infection with either of two subspecies of the parasite . Due to a lack of economic incentive to develop new drugs, current treatments have severe limitations in terms of safety, efficacy, and ease of administration. In an effort to develop new HAT therapeutics, we report the structure-activity relationships around for a series of benzoxazepinoindazoles previously identified through a high-throughput screen of human kinase inhibitors, and the subsequent experiments for HAT.

In 2014, a published report of the high-throughput screen of>42,000 kinase inhibitors from GlaxoSmithKline against T. brucei identified 797 potent and selective hits. From this rich data set, we selected NEU-0001101 (1) for hit-to-lead optimization.

It is widely accepted that the sources of information used to guide interceptive actions depend on conflicting spatiotemporal task demands. However, there is a paucity of evidence that shows how information pick-up during interceptive actions is adapted to such conflicting constraints. The present study therefore examined the effects of systematic manipulations of spatiotemporal constraints on performance, timing and gaze in an in situ interceptive action.

The purpose of this study was to examine the relations among students' perceptions of motivational climate, sportsmanship attitudes, and attitudes toward content and teachers in physical education. 910 secondary school students ages 13 to 16 years (M=14.3, SD=1.

The highly polymorphic D1S80 locus has no known genetic function. However, this variable number of tandem repeats (VNTR) locus has been highly valuable in forensic identification. In this study we report the allele and genotype frequencies of five African populations (Benin, Cameroon, Egypt, Kenya, and Rwanda), which can be used as databases to help characterize populations and identify individuals.

A simple and inexpensive single-nucleotide polymorphism (SNP) analysis procedure is described that uses the Fotodyne Analyst System equipped with the Gel-Pro Analysis software to compare the relative fluorescent intensity of ethidium bromide stained and MboI restricted amplicons from male individuals. The different intensity ratios reflect the ratio of repetitive elements with and without an MboI restriction enzyme site. The polymerase chain reaction (PCR) products represent a reiterated sequence within the Y-linked deleted in azoospermia (DAZ) complex involved in male fertility in humans.

The evolution of the deleted in azoospermia (DAZ) gene family supports prevalent theories on the origin and development of sex chromosomes and sexual dimorphism. The ancestral DAZL gene in human chromosome 3 is known to be involved in germline development of both males and females. The available phylogenetic data suggest that some time after the divergence of the New World and Old World monkey lineages, the DAZL gene, which is found in all mammals, was copied to the Y chromosome of an ancestor to the Old World monkeys, but not New World monkeys.
