A 17-year-old girl presented with a distinct phenotype mainly featuring craniofacial dysmorphism, including a disproportioned large, round, elongated face; hypertelorism; deep-set eyes with short palpebral fissures; obesity (BMI 37), and a neuropsychiatric disorder with high-functioning autism. Postnatal conventional cytogenetic analyses from peripheral blood revealed a mosaic small supernumerary marker chromosome (sSMC) with a mos 47,XX,+mar[7]/46,XX[43] karyotype. By cenM-FISH technique, the sSMC was identified as a ring derivative of chromosome 5...

An increasing number of studies are suggesting that plant viruses, including southern rice black-streaked dwarf virus (SRBSDV), can adversely affect biological characteristics of insect vectors by unknown mechanisms. To study the adverse effect of SRBSDV at cellular level on the insect vector, we promoted viral infection by the disruption of the small interfering RNA (siRNA) pathway. The transmission electron microscopy was utilized to describe the ultrastructural changes that occurred in insects when the core component of the siRNA pathway, Dicer-2, was knocked down...

Here, we observe that a sub-monolayer CdS shell on PbS quantum dots (QDs) enhances triplet energy transfer (TET) by suppressing competitive charge transfer from QDs to molecules. The CdS shell increases the linear photon upconversion quantum yield (QY) from 3.5% for PbS QDs to 5.0% for PbS/CdS QDs when functionalized with a tetracene acceptor, 5-CT. While transient absorption spectroscopy reveals that both PbS and PbS/CdS QDs show the formation of the 5-CT triplet (with rate constants of 5.91 ±0.60 ns-1 and 1...

Computational analysis of promoters is hindered by the complexity of their architecture. In less studied genomes with complex organization, false positive promoter predictions are common. Accurate identification of transcription start sites and core promoter regions remains an unsolved problem. In this paper, we present a comprehensive analysis of genomic features associated with promoters and show that probabilistic integrative algorithms-driven models allow accurate classification of DNA sequence into "promoters" and "non-promoters" even in absence of the full-length cDNA sequences...

Anhedonia is defined as a diminished ability to obtain pleasure from otherwise positive stimuli. Anxiety and mood disorders have been previously associated with dysregulation of the reward system, with anhedonia as a core element of major depressive disorder (MDD). The aim of the present study was to investigate whether stress-induced anhedonia could be prevented by treatments with escitalopram or novel herbal treatment (NHT) in an animal model of depression. Unpredictable chronic mild stress (UCMS) was administered for 4 weeks on ICR outbred mice...

#7
Joakim Ågren, Marc Oliver Schäfer, Eva Forsgren
American foulbrood (AFB), caused by Paenibacillus larvae, is a devastating disease in honeybees. In most countries, the disease is controlled through compulsory burning of symptomatic colonies causing major economic losses in apiculture. The pathogen is endemic to honeybees world-wide and is readily transmitted via the movement of hive equipment or bees. Molecular epidemiology of AFB currently largely relies on placing isolates in one of four ERIC-genotypes. However, a more powerful alternative is multi-locus sequence typing (MLST) using whole-genome sequencing (WGS), which allows for high-resolution studies of disease outbreaks...

Quentin Eichbaum
Whereas the business professions have long recognized that conflict can be a source of learning and innovation, the health professions still tend to view conflict negatively as being disruptive, inefficient, and unprofessional. As a consequence, the health professions tend to avoid conflict or resolve it quickly. This neglect to appreciate conflict's positive attributes appears to be driven in part by (1) individuals' fears about being negatively perceived and the potential negative consequences in an organization of being implicated in conflict, (2) constrained views and approaches to professionalism and to evaluation and assessment, and (3) lingering autocracies and hierarchies of power that view conflict as a disruptive threat...

PURPOSE: Few studies have examined the psychological and psychophysiological effects of recuperative music following exhaustive exercise. The main purpose of the present study was to examine the effects of two music conditions compared with a no-music control on psychological and psychophysiological recovery processes post-exercise. METHODS: A randomized, fully counterbalanced, crossover design was used. Core affect, salivary cortisol, heart rate, and blood pressure were measured before exhaustive exercise, immediately after, and in 10-, 20-, and 30-min intervals during passive recovery (21 women and 21 men; 20...

PURPOSE: Heat intolerance commonly affects the exercise capacity of people with multiple sclerosis (MS) during bouts of hot weather. Cold-water ingestion is a simple cooling strategy but its efficacy for prolonging exercise capacity with MS remains undetermined. We sought to identify whether cold-water ingestion blunts exercise-induced rises in body temperature and improves exercise tolerance in heat-sensitive individuals with MS. METHODS: On two separate occasions, 20 participants (10 relapsing-remitting MS (EDSS: 1-5); 10 age-matched healthy controls (CON)) cycled at ~40% VO2max at 30°C, 30%RH until volitional exhaustion (or a maximum of 60 min)...

With the advancement of high quality X-ray sources, it is now possible to create a molecular movie by following the electronic dynamics in real-time and real-space through time resolved X-ray diffraction. Here, we employ real-time time-dependent density functional theory (RT-TDDFT) to simulate the electronic dynamics after an impulse core or valence ionization in the glycine-phenylalanine (GF) dipeptide. The simulation yields the time-evolving dipole moment, the charge density, and the time-resolved X-ray diffraction signals...

Tetranuclear Ni complexes were synthesized with bonding to BH, NR, and O in atypical surface-like geometries. The previously reported electron-deficient cluster [((i)Pr3P)Ni]5H6 (1) reacts with N-methylmorpholine oxide to give [((i)Pr3P)Ni]4H4(μ4-O) (2), which contains O coordinated in the center of a square-plane arrangement of Ni atoms. Reaction of 1 with benzonitrile gave the square-planar tetranuclear Ni cluster [((i)Pr3P)Ni]4H4(μ4-NCH2Ph) (3), which contains an imido donor in a square-based-pyramidal geometry...

There is a pressing need to develop nanoplatforms that integrate multimodal therapeutics to improve treatment responses and prolong the survival of patients with unresectable hepatocellular carcinoma (HCC). Mesoporous silica-coated gold nanomaterials have emerged as a novel multifunctional platform combining tunable surface plasmon resonance and mesoporous properties that exhibit multimodality properties in cancer theranostics. However, their reduced radiation-absorption efficiency and limited surface area hinder their further radiochemotherapeutic applications...

Among nonhuman primates, the evolutionary underpinnings of variation in social structure remain debated, with both ancestral relationships and adaptation to current conditions hypothesized to play determining roles. Here we assess whether interspecific variation in higher-order aspects of female macaque (genus: Macaca) dominance and grooming social structure show phylogenetic signals, that is, greater similarity among more closely-related species. We use a social network approach to describe higher-order characteristics of social structure, based on both direct interactions and secondary pathways that connect group members...

Background: The MD Anderson Symptom Inventory (MDASI) is a brief, yet thorough, patient-reported outcomes measure for assessing the severity of common cancer-related symptoms and their interference with daily functioning. We report the development of an MDASI version tailored for use with Traditional Chinese Medicine in China (the MDASI-TCM). Methods: Chinese-speaking patients with mixed cancer types (n = 317) participated in the study. The development and validation process included four steps: 1) identify candidate TCM-specific items, with input from patients, oncologists, and TCM specialists; 2) eliminate candidate TCM items lacking relevance, based on patient report; 3) psychometrically examine the MDASI-TCM's validity and reliability in cancer patients receiving TCM-based care; and 4) cognitively debrief patients to assess the MDASI-TCM's relevance, understandability, and acceptability...

The term "whole-person cancer care"-an approach that addresses the needs of the person as well as treating the disease-is more widely understood in the United Kingdom than its synonym "integrative oncology." The National Health Service (NHS) provides free access to care for all, which makes it harder to prioritize NHS funding of whole-person medicine, where interventions may be multimodal and lacking in cost-effectiveness data. Despite this, around 30% of cancer patients are known to use some form of complementary or alternative medicine (CAM)...

Draft regulatory guidance suggests that if the processing of a child's personal data begins with the consent of a parent, then there is a need to find and defend an enduring consent through the child's growing capacity and on to their maturity. We consider the implications for health research of the UK Information Commissioner's Office's (ICO) suggestion that the relevant test for maturity is the Gillick test, originally developed in the context of medical treatment. Noting the significance of the welfare principle to this test, we examine the implications for the responsibilities of a parent to act as proxy for their child...

Northern Hemisphere alpine glaciers have been identified as a point of concentration and reemergence of legacy organochlorine pollutants (OCPs). In this review, we compile a selection of published literature combining long-range, global atmospheric transport and distribution-based compartmental environmental flux models, as well as data from glacial meltwater, ice core, crevasse and proglacial lake sediment studies. Regional studies of ice and meltwater in alpine glaciers of the northern latitudes show similarities in sample deposition profiles and concentration due to chemical atmospheric residence time, precipitation type and glacier flow rates...
