The genera Holocnemus Simon, 1873 and Crossopriza 1893 are revised. Together with Stygopholcus Kratochvíl, 1932 (revised recently) the newly described genus Maghreba gen. nov., they constitute spotted-leg clade within northern of Smeringopinae. Males females in this group characterized by dark marks on leg femora tibiae. native area ranges from Africa Mediterranean to Central Asia NW India. A m...

BACKGROUND Exercise-based spectral T-wave alternans (TWA) has been proposed as a noninvasive tool-identifying patients at risk of sudden cardiac death (SCD) and cardiac mortality. Prior studies have indicated that ambulatory electrocardiogram (AECG)-based TWA is an important alternative platform to exercise for risk stratification of cardiac events. This study sought to review data regarding 24...

INTRODUCTION Nigeria has one of the highest maternal mortality ratios in the world. Poor health outcomes are linked to weak health infrastructure, barriers to service access, and consequent low rates of service utilization. In the northern state of Jigawa, a pilot study was conducted to explore the feasibility of deploying resident female Community Health Extension Workers (CHEWs) to rural area...

Chemical signals play an important role in spider sexual communication, yet the chemistry of spider sex pheromones remains poorly understood. Chemical identification of male-produced pheromone-mediating sexual behaviour in spiders has also, to our knowledge, not been reported before. This study aimed to examine whether chemically mediated strategies are used by males of the spider Pholcus beiji...

We analysed seven genetic markers sampled from 165 pholcids and 34 outgroups in order to test and improve the recently revised classification of the family. Our results are based on the largest and most comprehensive set of molecular data so far to study pholcid relationships. The data were analysed using parsimony, maximum-likelihood and Bayesian methods for phylogenetic reconstruction. We sho...

Leg autotomy can be a very effective strategy for escaping a predation attempt in many animals. In spiders, autotomy can be very common (5-40% of individuals can be missing legs) and has been shown to reduce locomotor speeds, which, in turn, can reduce the ability to find food, mates, and suitable habitat. Previous work on spiders has focused mostly on the influence of limb loss on horizontal m...

PVT1 was originally identified as a transcriptional unit from a human homologous sequence to Pvt1, which was cloned from murine plasmacytoma with t(6;15). Previous studies have revealed various genetic alterations in the PVT1 locus, including chromosome translocation, amplification, chromothripsis, and single nucleotide polymorphisms in human diseases, suggesting important roles of PVT1 in the ...
