Molecular mapping studies which aim to identify genetic basis of diverse agronomic traits are vital for marker-assisted crop improvement. Numerous Quantitative Trait Loci (QTLs) mapped in rice span long genomic intervals with hundreds to thousands of genes, which limits their utilization for marker-assisted genetic enhancement of rice. Although potent, fine mapping of QTLs is challenging task as it requires screening of large number of segregants to identify suitable recombination events. Association mapping offers much higher resolution as compared to QTL mapping, but detects considerable number of spurious QTLs...

The genus Platystigma Kennedy, 1920 is revalidated based mainly on the third segment of the penis that is plate-like, whereas in the other Pseudostigmatidae it is a flagellum. Dijkstra et al (2014) have merged this family into the Coenagrionidae. However, we prefer to maintain the long-used name Pseudostigmatidae until more detailed phylogenetic studies with more sampling are done. Eight species are here considered in the genus, three of which are described as new: P. humaita, P. minimum and P. quadratum. The genus is divided in two species group, jocaste and quadratum, the latter studied here...

The species of Pritha Lehtinen, 1967 in Italy are revised for the first time, and a preliminary putative diagnosis for the genus is provided. Two new Italian species are described: Pritha parva sp. nov. (male and female) and P. sagittata sp. nov. (male and female). P. pallida (Kulczyński, 1897) and the type species P. nana (Simon, 1868) are entirely re-described. The copulatory organs, some other somatic characters and the habitus of each sex of the four Italian species are illustrated and photographed at high magnifications...

Ultrafiltration is an effective barrier to waterborne pathogens including viruses. Challenge testing is commonly used to test the inherent reliability of such systems. Performance validation seeks to demonstrate the adequate reliability of the treatment system. Appropriate and rigorous data analysis is an essential aspect of validation testing. In this study we used Bayesian analysis to assess the performance of a full-scale ultrafiltration system which was validated and revalidated after five years of operation...

The Himalaya presents an outstanding geologically active orogen and biodiversity hotspot. However, our understanding of the historical biogeography of its fauna is far from comprehensive. Many taxa are commonly assumed to have originated from China-Indochina and dispersed westward along the Himalayan chain. Alternatively, the "Tibetan-origin hypothesis" suggests primary diversification of lineages in Paleo-Tibet, and secondary diversification along the slopes of the later uplifted Greater Himalaya. We test these hypotheses in high-mountain megophryid anurans (Scutiger)...

Memantine is a drug approved for the treatment of moderate-to-severe Alzheimer's disease (AD), and there is ongoing research on the potential expansion of its clinical applicability. Published data on the pharmacokinetics of memantine in the mouse is still incomplete, particularly for chronic administration regimens and mouse models of specific genetic disorders. Down's syndrome (DS) is a genetic disorder known to affect multiple organs and systems, with the potential to alter significantly drug pharmacokinetics...

We studied the diversity within the former genus Gymnangium in the South West Indian Ocean by using an integrative approach of both traditional (morphology-based) and modern molecular taxonomy. Nine species were recorded in the material collected. A total of 97 16S mitochondrial DNA sequences and 54 Calmodulin nuclear sequences from eight Gymnangium/Taxella species were analyzed. We found both morphological and molecular differences in the studied Gymnangium species that make it necessary to split the genus...

MicroRNAs (miRNAs) play vital roles in the adaptive response of plants to various abiotic and biotic stresses. Tall fescue (Festuca arundinacea Schreb.) is a major cool-season forage and turf grass species which is severely influenced by heat stress. To unravel possible heat stress-responsive miRNAs, high-throughput sequencing was employed for heat-tolerant PI578718 and heat-sensitive PI234881 genotypes growing in presence and absence of heat stress (40°C for 36h). By searching against the miRBase database, among 1421 reference monocotyledon miRNAs, more than 850 were identified in all samples...

BACKGROUND: Patient-reported outcome measures (PROMs) are increasingly used to quantify patients' perceptions of functional ability. The American Medical Association and NIH suggest patient materials be written at or below 6th to 8th grade reading levels, respectively, yet one recent study asserts that few PROMs comply with these recommendations, and suggests that the majority of PROMs are written at too high of a reading level for self-administered patient use. Notably, this study was limited in its use of only one readability algorithm, although there is no commonly accepted, standard readability algorithm for healthcare-related materials...

Peloso et al. (2015: PELOSO) published a comprehensive phylogenetic study of the frog family Microhylidae, which resulted in the discovery that several taxa were not monophyletic. To remedy this, a series of nomenclatural changes were proposed (several generic synonymies and two new subfamilies named). A recent study published in this journal by Scherz et al. (2016: SCHERZ), provided a novel phylogeny for the Malagasy subfamily Cophylinae. SCHERZ dispute the analyses and taxonomic conclusions of PELOSO. Their study is, however, based on substantial reduction of data from the PELOSO study, limited addition of new data, and different analytical methods...

The Eastern Cape redfin, Pseudobarbus afer, has long been considered to be a single widespread and variable species occurring in multiple isolated river systems in the Cape Fold Ecoregion (CFE) at the southern tip of Africa. Mitochondrial cytochrome b and control region sequence data of individuals from populations currently assigned to Pseudobarbus afer across the species' distribution range revealed existence of four deeply divergent taxonomic units: (i) the Mandela lineage confined to the Sundays, Swartkops and Baakens river systems, (ii) the Krom lineage endemic to the Krom River system, (iii) the St Francis lineage occurring in the Gamtoos and adjacent river systems, and (iv) the Forest lineage occurring in several coastal river systems from the Tsitsikamma to the Klein Brak River system...

BACKGROUND AND PURPOSE: The Gugging Swallowing Screen (GUSS) is a tool to screen aspiration risk in acute stroke. We aimed to replicate its validity in a larger second cohort of patients with acute stroke, including the more severe with a National Institutes of Health Stroke Scale (NIHSS) ≥ 15. METHODS: In a prospective, double-blind design, the GUSS was validated with the Fiberoptic Endoscopic Evaluation of Swallowing scale. Patients were categorized into different stroke severities as assessed by the NIHSS, and the diagnostic properties were calculated separately for each subgroup...
