Molecular stratification of endometrioid ovarian carcinoma predicts clinical outcome.

Endometrioid ovarian carcinoma (EnOC) demonstrates substantial clinical and molecular heterogeneity. Here, we report whole exome sequencing of 112 EnOC cases following rigorous pathological assessment. We detect a high frequency of mutation in CTNNB1 (43%), PIK3CA (43%), ARID1A (36%), PTEN (29%), KRAS (26%), TP53 (26%) and SOX8 (19%), a recurrently-mutated gene previously unreported in EnOC.

Integrated terrestrial-freshwater planning doubles conservation of tropical aquatic species.

Conservation initiatives overwhelmingly focus on terrestrial biodiversity, and little is known about the freshwater cobenefits of terrestrial conservation actions. We sampled more than 1500 terrestrial and freshwater species in the Amazon and simulated conservation for species from both realms. Prioritizations based on terrestrial species yielded on average just 22% of the freshwater benefits achieved through freshwater-focused conservation.

Reproducibility across single-cell RNA-seq protocols for spatial ordering analysis.

As newer single-cell protocols generate increasingly more cells at reduced sequencing depths, the value of a higher read depth may be overlooked. Using data from three different single-cell RNA-seq protocols that lend themselves to having either higher read depth (Smart-seq) or many cells (MARS-seq and 10X), we evaluate their ability to recapitulate biological signals in the context of spatial reconstruction. Overall, we find gene expression profiles after spatial reconstruction analysis are highly reproducible between datasets despite being generated by different protocols and using different computational algorithms.

The Method of Surgical Lip Repair Affects Speech Outcomes in Children With Bilateral Cleft Lip and Palate.

Objective: It was hypothesized that lip repair protocols in children with bilateral cleft lip and palate (BCLP) would affect development of bilabial consonants /m/ /b/ /p/. This study compared speech outcomes in 2 surgical groups.

Design: A retrospective case note investigation.

Simple trapeziectomy versus trapeziectomy with flexor carpi radialis suspension: a 17-year follow-up of a randomized blind trial.

The purpose of this study was to investigate if there were any significant differences in the long-term outcomes of patients who participated in a randomized trial of trapeziectomy alone compared with trapeziectomy with ligament reconstruction and tendon interposition (LRTI). Sixty-five patients were invited for a follow-up visit at a mean of 17 years (range 15-20) postoperatively. Twenty-eight patients attended, who had 34 operations, 14 trapeziectomy alone and 20 with LRTI.

Transglutaminase-Mediated Cross-Linking of Tropoelastin to Fibrillin Stabilises the Elastin Precursor Prior to Elastic Fibre Assembly.

Elastic fibres are essential components of all mammalian elastic tissues such as blood vessels, lung and skin, and are critically important for the mechanical properties they endow. The main components of elastic fibres are elastin and fibrillin, where correct formation of elastic fibres requires a fibrillin microfibril scaffold for the deposition of elastin. It has been demonstrated previously that the interaction between fibrillin and tropoelastin, the elastin precursor, increases the rate of assembly of tropoelastin.

Patterns of food parenting practices regarding junk food and sugary drinks among parent-child dyads.

Background: Children's food preference and intake patterns are affected by parental child feeding practices. The objective was to determine patterns of food parenting practices regarding junk food and sugary drinks (JS) and investigate their associations with demographic characteristics and dietary intake in a large cohort of parents and their children (12-17 years).

Methods: Dyadic survey data from the cross-sectional, internet-based Family Life, Activity, Sun, Health, and Eating Study, conducted in 2014, were analyzed using latent class analysis to identify patterns of use for six JS parenting practices - negative emotions, restriction, monitoring, availability, modeling, and child involvement - based on parent and child report.

The impact of personality, morphotype and shore height on temperature-mediated behavioural responses in the beadlet anemone Actinia equina.

Between-individual variation in behavioural phenotype, termed personality, is an important determinant of how populations cope with acute environmental fluctuation related to climate change. Personality in the beadlet sea anemone Actinia equina is linked to genetically distinct morphotypes, which are associated with different heights on the shore. In the intertidal zone, high-shore environments experience more environmental fluctuation due to longer periods of exposure, and animals adapted to live in these environments are predicted to deal more effectively with environmental perturbation than their low-shore counterparts.

Synchronized Inflations Generate Greater Gravity-Dependent Lung Ventilation in Neonates.

Objective: To describe the regional distribution patterns of tidal ventilation within the lung during mechanical ventilation that is synchronous or asynchronous with an infant's own breathing effort.

Study Design: Intubated infants receiving synchronized mechanical ventilation at The Royal Children's Hospital neonatal intensive care unit were studied. During four 10-minute periods of routine care, regional distribution of tidal volume (V; electrical impedance tomography), delivered pressure, and airway flow (Florian Respiratory Monitor) were measured for every inflation.

Isolation of novel citrus and plum fruit promoters and their functional characterization for fruit biotechnology.

Background: Promoters that confer expression in fruit tissues are important tools for genetic engineering of fruit quality traits, yet few fruit-specific promoters have been identified, particularly for citrus fruit development.

Results: In this study, we report five citrus fruit-specific/preferential promoters for genetic engineering. Additionally, we have characterized a novel fruit-preferential promoter from plum.

Biologically Functionalized Expanded Polytetrafluoroethylene Blood Vessel Grafts.

Cardiovascular diseases plague human health because of the lack of transplantable small-diameter blood vessel (SDBV) grafts. Although expanded polytetrafluoroethylene (ePTFE) has the potential to be used as a biocompatible material for SDBV grafts, long-term patency is still the biggest challenge. As discussed in this paper, by virtue of a novel material formulation and a new and benign alcohol/water lubricating agent, biofunctionalized ePTFE blood vessel grafts aimed at providing long-term patency were fabricated.

Epidemiology and survival of liposarcoma and its subtypes: A dual database analysis.

Purpose: Liposarcoma (LPS) is a one of the most commonly diagnosed soft tissue sarcomas. Little is known about the epidemiology and prognosis of each subtype. We present an analysis of epidemiology and survival of the subtypes of LPS using a national database.

Cantaloupe Facilitates Typhimurium Survival Within and Transmission Among Adult House Flies ( L.).

serovar Typhimurium is a pathogen harbored by livestock and shed in their feces, which serves as an acquisition source for adult house flies. This study used a green fluorescent protein (GFP) expressing strain of Typhimurium to assess its acquisition by and survival within house flies, and transmission from and between flies in the presence or absence of cantaloupe. Female house flies were exposed to manure inoculated with either sterile phosphate-buffered saline or GFP- Typhimurium for 12 h, then used in four experiments each performed over 24 h.

Association Between Statewide School Closure and COVID-19 Incidence and Mortality in the US.

Importance: In the US, states enacted nonpharmaceutical interventions, including school closure, to reduce the spread of coronavirus disease 2019 (COVID-19). All 50 states closed schools in March 2020 despite uncertainty if school closure would be effective.

Objective: To determine if school closure and its timing were associated with decreased COVID-19 incidence and mortality.

A new role for orthopaedic surgeons: ongoing changes, lessons learned, and perspectives from a level I trauma center during the COVID-19 pandemic.

The COVID-19 pandemic has redefined global health care. With almost 13 million confirmed cases worldwide, medical professionals have been forced to modify their practice to take care of an expanded, critically ill population. Institutions have been challenged to implement innovative ways to maximize the utility and the safety of residents and personnel.

KinderMiner Web: a simple web tool for ranking pairwise associations in biomedical applications.

Many important scientific discoveries require lengthy experimental processes of trial and error and could benefit from intelligent prioritization based on deep domain understanding. While exponential growth in the scientific literature makes it difficult to keep current in even a single domain, that same rapid growth in literature also presents an opportunity for automated extraction of knowledge via text mining. We have developed a web application implementation of the KinderMiner algorithm for proposing ranked associations between a list of target terms and a key phrase.

Synthesis of SMT022357 enantiomers and evaluation in a Duchenne muscular dystrophy mouse model.

Following on from ezutromid, the first-in-class benzoxazole utrophin modulator that progressed to Phase 2 clinical trials for the treatment of Duchenne muscular dystrophy, a new chemotype was designed to optimise its physicochemical and ADME profile. Herein we report the synthesis of SMT022357, a second generation utrophin modulator preclinical candidate, and an asymmetric synthesis of its constituent enantiomers. The pharmacological properties of both enantiomers were evaluated and .

Blood lactate and rectal temperature can predict exit velocity of beef feedlot steers.

Interest in beef cattle temperament has increased due to growing consumer awareness of animal welfare and increased concern for handler safety. Temperament measures are based on behavioral responses to a perceived stressor. Subjective chute scoring has been used to give a numeric value to temperament; however, the subjectivity and variability among observers have been questioned.

Acute and chronic stress prevents responses to pain in zebrafish: evidence for stress-induced analgesia.

The state of an animal prior to the application of a noxious stimulus can have a profound effect on their nociceptive threshold and subsequent behaviour. In mammals, the presence of acute stress preceding a painful event can have an analgesic effect whereas the presence of chronic stress can result in hyperalgesia. While considerable research has been conducted on the ability of stress to modulate mammalian responses to pain, relatively little is known about fish.

Patterns of Food Parenting Practices Regarding Fruit and Vegetables among Parent-Adolescent Dyads.

The study's objective was to determine patterns of food parenting practices regarding fruit and vegetables (FV) and their associations with demographic characteristics and dietary intake in parents and adolescents (12-17 years). Dyadic survey data from Family Life, Activity, Sun, Health, and Eating, a cross-sectional, Internet-based study, conducted in 2014 were analyzed using latent class analysis. Self-report model covariates included adolescent age and parent and adolescent sex, BMI, FV intake, and FV legitimacy of parental authority (FV-LPA).

Risk factors of venous thromboembolism in patients with benign and malignant musculoskeletal tumors: a dual database analysis.

Purpose: Venous thromboembolism (VTE) is a potentially life-threatening condition associated with both orthopaedic surgery and tumour growth. In this study, we identify risk factors associated with VTE in patients with musculoskeletal tumours using two national datasets.

Methods: The ACS-NSQIP and NIS databases were queried for patients undergoing surgery with a diagnosis of benign or malignant musculoskeletal tumours.

A comprehensive study of allele drop-in over an extended period of time.

Some probabilistic mixture programmes take into account the presence of additional alleles by utilising drop-in models [1-4]. Although the precise details of the various models vary, at their core, they all rely on two basic assumptions - (1) that drop-in events occur independently of each other and (2) the frequency of individual dropped-in alleles mirrors the composition within some specified population. In order to examine the robustness of these assumptions, we have collected data on allele drop-in and contamination events in 28,842 negative control samples processed over a three year period in our DNA crime laboratory.

Engineered Perineural Vascular Plexus for Modeling Developmental Toxicity.

There is a vital need to develop in vitro models of the developing human brain to recapitulate the biological effects that toxic compounds have on the brain. To model perineural vascular plexus (PNVP) in vitro, which is a key stage in embryonic development, human embryonic stem cells (hESC)-derived endothelial cells (ECs), neural progenitor cells, and microglia (MG) with primary pericytes (PCs) in synthetic hydrogels in a custom-designed microfluidics device are cocultured. The formation of a vascular plexus that includes networks of ECs (CD31+, VE-cadherin+), MG (IBA1+), and PCs (PDGFRβ+), and an overlying neuronal layer that includes differentiated neuronal cells (βIII Tubulin+, GFAP+) and radial glia (Nestin+, Notch2NL+), are characterized.

Environmental and Sex Effects on Bacterial Carriage by Adult House Flies ( L.).

Adult house flies frequent microbe-rich sites such as urban dumpsters and animal facilities, and encounter and ingest bacteria during feeding and reproductive activities. Due to unique nutritional and reproductive needs, male and female flies demonstrate different interactions with microbe-rich substrates and therefore dissemination potential. We investigated culturable aerobic bacteria and coliform abundance in male and female flies (n = 107) collected from urban (restaurant dumpsters) and agricultural (dairy farm) sites.
