Hepatic sinusoidal obstruction syndrome (previously named veno-occlusive disease, SOS/VOD) is a serious complication of allogeneic stem cell transplantation (HSCT). Early identification of patients at risk of SOS/VOD may possibly improve the outcome and reduce mortality. Rotation thromboelastometry (ROTEM) is global assay allowing for the precise assessment of both bleeding and thrombotic conditions, however, its usefulness in patients undergoing HSCT for acute leukaemia has not been studied.We evaluated the thromboelastometry parameters in patients undergoing allogeneic HSCT for acute leukaemia to identify candidate biomarkers of SOS/VOD occurrence...

Zika virus (ZIKV) is an arbovirus of the Flavivirus genus, and it has an envelope and a single RNA molecule. In early 2016, the World Health Organization declared ZIKV infection to be an emerging global health threat. The major transmission route of the virus to humans is Aedes mosquitoes. ZIKV can be transmitted between humans by transplacental, perinatal, and sexual routes and via blood and body fluids. ZIKV infection usually results in a mild and self-limiting disease with low-grade fever, conjunctivitis, and periorbital edema...

Kohlschutter-Tönz syndrome (KTS) is a rare autosomal-recessive disorder of childhood onset characterized by global developmental delay, spasticity, epilepsy, and amelogenesis imperfecta. Rogdi, an essential protein, is highly conserved across metazoans, and mutations in Rogdi are linked to KTS. However, how certain mutations in Rogdi abolish its physiological functions and cause KTS is not known. In this study, we determined the crystal structure of human Rogdi protein at atomic resolution. Rogdi forms a novel elongated curved structure comprising the α domain, a leucine-zipper-like four-helix bundle, and a characteristic β-sheet domain...

Yunis-Varón syndrome (YVS) is an autosomal recessive disorder comprising skeletal anomalies, dysmorphism, global developmental delay and intracytoplasmic vacuolation in brain and other tissues. All hitherto-reported pathogenic variants affect FIG4, a lipid phosphatase involved in phosphatidylinositol (3,5)-bisphosphate [PtdIns(3,5)P2] metabolism. FIG4 interacts with PIKfyve, a lipid kinase, via the adapter protein VAC14; all subunits of the resulting complex are essential for PtdIns(3,5)P2 synthesis in the endolysosomal membrane compartment...

BACKGROUND: Nicolaides-Baraitser Syndrome(NCBRS) is an extremely rare condition which has been reported in only a few cases. NCBRS is a distinct clinical condition with typical clinical features of pre- and post-natal global developmental delay, impaired speech, and seizures. Microcephaly, sparse hair, anteverted alae nasi, undefined philtrum, prominence of distal phalanges and interphalangeal joints, and short metacarpals are also typical of NCBRS. CASE REPORT: There are no reported cases in the literature of patients with NCBRS presenting with multiple dental impactions, and to the authors' knowledge, this is the 28th fully documented case of NCBRS and only 75 cases identified as potentially having NCBRS...

BACKGROUND: There is currently no disease-modifying treatment available to halt or delay the progression of the disease pathology in dementia. An agreed core set of the best-available and most appropriate outcomes for disease modification would facilitate the design of trials and ensure consistency across disease modification trials, as well as making results comparable and meta-analysable in future trials. OBJECTIVES: To agree a set of core outcomes for disease modification trials for mild to moderate dementia with the UK dementia research community and patient and public involvement (PPI)...

Despite the recent global increase in fatal endemic outbreaks of proliferative enteropathy (PE) caused by the obligate intracellular bacterium Lawsonia intracelluralis (LI) in the swine industry, development of effective prevention strategies or immunodiagnostic tests has been delayed due to the difficulty of cultivating this pathogen in vitro. Although several genetic analyses have been performed at the level of gene transcription after the complete genome sequence of LI was made available, the mechanism of LI infection and virulence genes remain unidentified...

BACKGROUND: Brain injury can be identified as early as day two of life in asphyxiated newborns treated with hypothermia, when using diffusion magnetic resonance imaging (MRI). However, it remains unclear whether these diffusion changes can predict future neurodevelopment. This study aimed to determine whether abnormal early diffusion changes in newborns treated with hypothermia are associated with adverse neurodevelopmental outcome at age two years. METHODS: Asphyxiated newborns treated with hypothermia were enrolled prospectively...

BACKGROUND: Somatosensory (SSEP) and brainstem auditory (BAEP) evoked potentials are neurophysiological tools which, respectively, explore the intracranial conduction time (ICCT) and the intrapontine conduction time (IPCT). The prognostic values of prolonged cerebral conduction times in deeply sedated patients have never been assessed. Sedated patients are at risk of developing new neurological complications, undetected. In this prospective observational bi-center pilot study, we investigated whether early impairment of SSEP's ICCT and/or BAEP's IPCT could predict in-ICU mortality or altered mental status (AMS), in deeply sedated critically ill patients...

BACKGROUND: Many women have undergone both resectoscopic and nonresectoscopic (or global) endometrial ablation (EA) during the past 20 years. These women are now approaching their sixth and seventh decades of life, a time frame in which endometrial carcinoma (EC) is most frequently diagnosed. DATABASE: In several reports, surgeons have expressed concern that endometrial ablation may leave a sequestered island of EC that may escape detection, possibly delaying its diagnosis or causing it to appear at an advanced stage...

The computational and cognitive properties of neural systems are often thought to be implemented in terms of their (stochastic) network dynamics. Hence, recovering the system dynamics from experimentally observed neuronal time series, like multiple single-unit recordings or neuroimaging data, is an important step toward understanding its computations. Ideally, one would not only seek a (lower-dimensional) state space representation of the dynamics, but would wish to have access to its statistical properties and their generative equations for in-depth analysis...

Exposure to ionizing radiation greatly increases the risk of developing papillary thyroid carcinoma (PTC), especially during childhood, mainly due to gradual inactivation of DNA repair genes and DNA damages. Recent molecular characterization of PTC revealed DNA methylation deregulation of several promoters of DNA repair genes. Thus, epigenetic silencing might be a plausible mechanism for the activity loss of tumor suppressor genes in radiation-induced thyroid tumors. Herein, we investigated the impact of ionizing radiation on global methylation and CpG islands within promoter regions of homologous recombination (HR) and non-homologous end joining (NHEJ) genes, as well as its effects on gene expression, using two well-established normal differentiated thyroid cell lines (FRTL5 and PCCL3)...

OBJECTIVE Delayed cerebral ischemia (DCI) following subarachnoid hemorrhage (SAH) is one of the major contributors to poor outcome. It is crucial to be able to detect early signs of DCI to prevent its occurrence. The objective of this study was to determine if low cerebral blood flow (CBF) measurements and pathological microdialysis parameters measured at the bedside can be observed early in patients with SAH who later developed DCI. METHODS The authors included 30 patients with severe SAH. The CBF measurements were performed at Day 0-3 after disease onset, using bedside xenon-CT...

Obesity is a global epidemic that has shown a steady increase in morbimortality indicators; it is considered a social problem and entails serious health risks. One of the alternatives in the treatment of obesity is the traditional use of medicinal plants, which supports the research and development of obesity phytotherapy. In this article, we provide information about ethnopharmacological species used to treat obesity, through an electronic search of the periodical databases Web of Science, Scopus, PubMed and Scielo, considering the period 1996-2015 and using the descriptors "plants for obesity", "ethnopharmacology for obesity" and "anti-obesity plants" in both Portuguese and English...

In this paper, we extensively study the global asymptotic stability problem of complex-valued neural networks with leakage delay and additive time-varying delays. By constructing a suitable Lyapunov-Krasovskii functional and applying newly developed complex valued integral inequalities, sufficient conditions for the global asymptotic stability of proposed neural networks are established in the form of complex-valued linear matrix inequalities. This linear matrix inequalities are efficiently solved by using standard available numerical packages...

High proportions of hypothetical proteins exist in genomic databases of fungi, including putative secretory proteins (PSPs) likely involved in fungal invasion and virulence. Here we characterize one of many PSPs revealed in the previous transcriptome of Beauveria bassiana (a fungal insect pathogen) infecting a global lepidopteran pest and name it vacuole-localized protein 4 (VLP4) because this small, domain-lacking protein (22.96 kDa) was specifically localized in the vacuoles of hyphal cells. Deletion of VLP4 resulted in repression of almost all genes acting in autophagy and central development pathways...
