The RNA quality control pathway nonsense-mediated mRNA decay targets cellular and viral RNAs to restrict KSHV
Nature Communications, Published online: 03 July 2020; doi:10.1038/s41467-020-17151-2Cellular nonsense-mediated mRNA decay (NMD) has been shown to play a role in defense against RNA viruses. Here, Zhao et al. show that NMD restricts the DNA virus Kaposi sarcoma-associated herpesvirus (KSHV) via targeting both cellular and viral transcripts leading to inhibition of KSHV lytic reactivation.

The induction and function of the anti-inflammatory fate of T<sub>H</sub>17 cells
Nature Communications, Published online: 03 July 2020; doi:10.1038/s41467-020-17097-5CD4+ T helper cells producing IL-17A (TH17 cells) can take on pathogenic or anti-inflammatory functions in context-specific manners. Here the authors show that the anti-inflammatory fate of TH17 cells contributes, via TGF-β signaling and induction of IL-10, to host immune tolerance, but also simultaneously dampens protective immunity against S. aureus.

The rapid development of the SARS-CoV-2 mediated COVID-19 pandemic has been the cause of significant health concern, highlighting the immediate need for effective antivirals. SARS-CoV-2 is an RNA virus that has an inherently high mutation rate. These mutations drive viral evolution and genome variability, thereby facilitating viruses to have rapid antigenic shifting to evade host immunity and to develop drug resistance. Viral RNA-dependent RNA polymerases (RdRp) perform viral genome duplication and...

Successful reproduction and survival are crucial to the continuation and resilience of corals globally. As reef waters warm due to climate change, episodic largescale tropical storms are becoming more frequent, drastically altering the near shore water quality for short periods of time. Therefore, it is critical that we understand the effects warming waters, fresh water input, and run-off have on sexual reproduction of coral. To better understand the effects of these near shore stressors on Hawaiian...

Abstract NALCN encodes a sodium ion leak channel expressed in the nervous system that conducts a persistent influx of sodium ions to facilitate action potential formation. Homozygous or compound heterozygous loss of function variants in NALCN cause infantile hypotonia with psychomotor retardation and characteristic facies‐1 (IHPRF1; OMIM 615419). Through exome and Sanger sequencing, we found two siblings of Afro‐Caribbean ancestry who are homozygous for a known NALCN pathogenic variant, p.Arg735Ter,...

Developmental delay, intellectual disability, short stature, subglottic stenosis, hearing impairment, onychodysplasia of the index fingers, and distinctive facial features: A newly reported autosomal recessive syndrome
Abstract We report on a multiply consanguineous Syrian family where two siblings, a boy and a girl, presented with a compilation of symptoms including developmental delay, severe intellectual disability, absent speech, hearing impairment, short stature, subglottic stenosis, increased length of the palpebral fissures, onychodysplasia of index fingers, scoliosis, genu valgum, and malpositioned toes. Two other individuals from the extended family with similar clinical features are also described. Array‐CGH...

Exploring the Inter-observer Agreement Among the Members of the Italian Consensus for the Classification and Reporting of Thyroid Cytology
Abstract Classification schemes for reporting thyroid cytology of fine needle aspiration (FNA) of thyroid nodules are largely used in clinical practice, but the level of inter-observer agreement among cytopathologists is poorly acknowledged. The present study aimed to explore the inter-observer agreement among the experienced authors of the 2014 Italian Consensus for Classification and Reporting of Thyroid Cytology (ICCRTC). A stratified randomization was performed in order to...

Management of pulmonary Scedosporium apiospermum infection by thoracoscopic surgery in an immunocompetent woman
Journal of International Medical Research, Volume 48, Issue 7, July 2020. The Scedosporium apiospermum complex is a group of emerging opportunistic fungal pathogens that affect both immunocompromised and immunocompetent individuals, most commonly via lung infection. Although they are resistant to many antifungal agents, this group of pathogens has a favorable susceptibility profile to azoles, especially voriconazole. Here, we describe the management of S. apiospermum infection in an otherwise healthy...

Female sperm storage mediates postcopulatory costs and benefits of ejaculate anticipatory plasticity in the guppy
Abstract Males of many species evolved the capability of adjusting their ejaculate phenotype in response to social cues to match the expected mating conditions. When females store sperm for a prolonged time, the expected fitness return of plastic adjustments of ejaculate phenotype may depend on the interval between mating and fertilization. While prolonged female sperm storage (FSS) increases the opportunity for sperm competition, as a consequence of the longer temporal overlap of ejaculates from...

Ecological fitting is the forerunner to diversification in a plant virus with broad host range
Abstract The evolution and diversification of ssRNA plant viruses are often examined under reductionist conditions that ignore potentially much wider biotic interactions. The host range of a plant virus is central to interactions at higher levels that are organised by both fitness and ecological criteria. Here we employ a strategy to minimise sampling biases across distinct plant communities, and combine it with a high throughput sequencing approach to examine the influence of four habitats on the...

Sleep disturbances and disability following work‐related injury and illness: Examining longitudinal relationships across three follow‐up waves
Summary Despite the high burden of sleep disturbances among the general population, there is limited information on prevalence and impact of poor sleep among injured workers. This study: (a) estimated the prevalence of sleep disturbance following work‐related injury; and (b) examined the longitudinal association between sleep disturbances and disability/functioning, accounting for reciprocal relationships and mental illness. Longitudinal survey data were collected from workers' compensation claimants...

Effects of sleep modulation during pregnancy in the mother and offspring: Evidences from preclinical research
Abstract Disturbed sleep during gestation may lead to adverse outcomes for both mother and child. Animal research plays an important role in providing insights into this research field by enabling ethical and methodological requirements that are not possible in humans. Here, we present an overview and discuss the main research findings related to the effects of prenatal sleep deprivation in animal models. Using systematic review approaches, we retrieved 42 articles dealing with some type of sleep...
