Discovering genotype-phenotype relationships with machine learning and the Visual Physiology Opsin Database (VPOD).

Background: Predicting phenotypes from genetic variation is foundational for fields as diverse as bioengineering and global change biology, highlighting the importance of efficient methods to predict gene functions. Linking genetic changes to phenotypic changes has been a goal of decades of experimental work, especially for some model gene families, including light-sensitive opsin proteins. Opsins can be expressed in vitro to measure light absorption parameters, including λmax-the wavelength of maximum absorbance-which strongly affects organismal phenotypes like color vision.

Optimizing and Implementing a Community-Based Group Fall Prevention Program: A Mixed Methods Study.

Falls and fall-related injuries among older adults are associated with decreased health. Therefore, fall prevention programs (FPPs) are increasingly important. However, the translation of such complex programs into clinical practice lacks insight into factors that influence implementation.

Synergistic co-utilization of biomass-derived sugars enhances aromatic amino acid production by engineered Escherichia coli.

Efficient co-utilization of mixed sugar feedstocks remains a biomanufacturing challenge, thus motivating ongoing efforts to engineer microbes for improved conversion of glucose-xylose mixtures. This study focuses on enhancing phenylalanine production by engineering Escherichia coli to efficiently co-utilize glucose and xylose. Flux balance analysis identified E4P flux as a bottleneck which could be alleviated by increasing the xylose-to-glucose flux ratio.

Levels of Physical Activity in Children with Extremity Fractures a Dutch Observational Cross-Sectional Study.

Background: Fractures are common in children and a frequent cause of emergency department (ED) visits. Fractures can cause long-term complications, such as growth problems. Research on fractures can reveal useful areas of focus for injury prevention.

Evaluation of Implementing TOM: A Group-Based Fall Prevention Programme among Community-Dwelling Older Adults in The Netherlands.

There is strong evidence that effective fall prevention elements exist, but the implementation into society remains difficult. The aim of the current study is to describe and evaluate the implementation of the fall prevention programme "Thuis Onbezorgd Mobiel" (TOM). This novel approach combines effective components into a multidisciplinary group-based programme for adults aged 65 years or older with an increased risk of falling.

The (cost-)effectiveness of an implemented fall prevention intervention on falls and fall-related injuries among community-dwelling older adults with an increased risk of falls: protocol for the in balance randomized controlled trial.

Background: Falls and fall-related injuries among older adults are a serious threat to the quality of life and result in high healthcare and societal costs. Despite evidence that falls can be prevented by fall prevention programmes, practical barriers may challenge the implementation of these programmes. In this study, we will investigate the effectiveness and cost-effectiveness of In Balance, a fourteen-week, low-cost group fall prevention intervention, that is widely implemented in community-dwelling older adults with an increased fall risk in the Netherlands.

Identification of community-dwelling older adults at risk of frailty using the PERSSILAA screening pathway: a methodological guide and results of a large-scale deployment in the Netherlands.

Background: Among community-dwelling older adults, frailty is highly prevalent and recognized as a major public health concern. To prevent frailty it is important to identify those at risk of becoming frail, but at present, no accepted screening procedure is available.

Methods: The screening process developed as part of the PERSSILAA project is a two-step screening pathway.

Genetic transformation of sp. 2T2.1, key fungal member of a lignocellulose-degrading microbial consortium.

sp. strain 2T2.1 is a key member of a microbial consortium that degrades lignocellulosic biomass.

Defence Anaesthesia transition from the Tri-Service Anaesthetic Apparatus to the Diamedica Portable Anaesthesia Machine 02.

Defence Anaesthesia is changing its draw-over anaesthetic capability from the Tri-Service Anaesthetic Apparatus (TSAA) to the Diamedica Portable Anaesthesia Machine 02 (DPA02). The DPA02 will provide a portable, robust, lightweight and simple method for delivering draw-over volatile anaesthesia with the option of positive pressure ventilation through manual or mechanical operation for paediatric and adult patients. The UK Defence Medical Services uses a modified configuration of the DPA02; this paper seeks to explain the rationale for the differing configurations and illustrates alternative assemblies to support integration with other Defence Anaesthesia equipment.

The Reliability of Using Tablet Technology for Screening the Health of Older Adults.

In this study, we assessed the reliability of using a tablet application for collecting health data among older adults, in comparison to using paper surveys for this goal. Test-retest reliability between the two modalities, usability, user experience factors, and older adults' preference were determined. The results show perfect agreement between tablet and paper for the SARC-F and high agreement for the SF-36 physical scale and EQ-5D.

Use of green fluorescent protein to monitor fungal growth in biomass hydrolysate.

A reporter gene encoding green fluorescent protein (GFP) was introduced into the ascomycete NRRL30616, and fluorescence of cultures was monitored as a measure of cell growth. Fluorescence in the GFP-expressing strain was measured during growth of cells in defined and complex media as well as in the liquor derived from pretreatment of corn stover, an agricultural residue. Fluorescence mirrored growth of cultures, as measured by optical density and counts of colony forming units.

User Experience, Actual Use, and Effectiveness of an Information Communication Technology-Supported Home Exercise Program for Pre-Frail Older Adults.

Objective: The main objective of this study was to investigate the use and user experience of an Information Communication Technology-supported home exercise program when offered for independent use to pre-frail older adults. Our secondary aim was to explore whether the program improved quality of life and health status compared to a control group.

Methods: A cohort multiple randomized controlled trail is being performed.

Transcriptomic and anatomic parcellation of 5-HTR expressing cortical interneuron subtypes revealed by single-cell RNA sequencing.

Cortical GABAergic interneurons constitute a highly diverse population of inhibitory neurons that are key regulators of cortical microcircuit function. An important and heterogeneous group of cortical interneurons specifically expresses the serotonin receptor 3A (5-HTR) but how this diversity emerges during development is poorly understood. Here we use single-cell transcriptomics to identify gene expression patterns operating in Htr3a-GFP+ interneurons during early steps of cortical circuit assembly.

Psychological factors associated with diabetes self-management among adolescents with Type 1 diabetes: A systematic review.

This review aims to synthesise the literature examining the psychosocial variables related to self-management (insulin adherence, non-adherence and administration, blood sugar monitoring, dietary behaviour, exercise behaviour) in adolescents with type 1 diabetes. A systematic search of three electronic databases was carried out and, after the application of eligibility criteria, 21 articles were assessed for quality prior to data extraction. Numerous psychological factors were found to be associated with self-management; however, correlations were typically small to moderate.

Maleic acid treatment of biologically detoxified corn stover liquor.

Elimination of microbial and enzyme inhibitors from pretreated lignocellulose is critical for effective cellulose conversion and yeast fermentation of liquid hot water (LHW) pretreated corn stover. In this study, xylan oligomers were hydrolyzed using either maleic acid or hemicellulases, and other soluble inhibitors were eliminated by biological detoxification. Corn stover at 20% (w/v) solids was LHW pretreated LHW (severity factor: 4.

Early-life serotonin dysregulation affects the migration and positioning of cortical interneuron subtypes.

Early-life deficiency of the serotonin transporter (SERT) gives rise to a wide range of psychiatric-relevant phenotypes; however, the molecular and cellular targets of serotonin dyregulation during neural circuit formation remain to be identified. Interestingly, migrating cortical interneurons (INs) derived from the caudal ganglionic eminence (CGE) have been shown to be more responsive to serotonin-mediated signalling compared with INs derived from the medial ganglionic eminence (MGE). Here we investigated the impact of early-life SERT deficiency on the migration and positioning of CGE-derived cortical INs in SERT-ko mice and in mice exposed to the SERT inhibitor fluoxetine during the late embryonic period.

Comprehensive, Integrative Genomic Analysis of Diffuse Lower-Grade Gliomas.

Background: Diffuse low-grade and intermediate-grade gliomas (which together make up the lower-grade gliomas, World Health Organization grades II and III) have highly variable clinical behavior that is not adequately predicted on the basis of histologic class. Some are indolent; others quickly progress to glioblastoma. The uncertainty is compounded by interobserver variability in histologic diagnosis.

Bioabatement with hemicellulase supplementation to reduce enzymatic hydrolysis inhibitors.

A stepwise removal of inhibitory compounds by bioabatement combined with hemicellulase supplementation was conducted to enhance cellulose hydrolysis of liquid hot water-pretreated corn stover. Results showed that the fungus Coniochaeta ligniaria NRRL30616 eliminated most of the enzyme and fermentation inhibitors from liquid hot water-pretreated corn stover hydrolysates. Moreover, addition of hemicellulases after bioabatement and before enzymatic hydrolysis of cellulose achieved 20% higher glucose yields compared to non-treated samples.

Serotonin receptor 3A controls interneuron migration into the neocortex.

Neuronal excitability has been shown to control the migration and cortical integration of reelin-expressing cortical interneurons (INs) arising from the caudal ganglionic eminence (CGE), supporting the possibility that neurotransmitters could regulate this process. Here we show that the ionotropic serotonin receptor 3A (5-HT(3A)R) is specifically expressed in CGE-derived migrating interneurons and upregulated while they invade the developing cortex. Functional investigations using calcium imaging, electrophysiological recordings and migration assays indicate that CGE-derived INs increase their response to 5-HT(3A)R activation during the late phase of cortical plate invasion.

Is there a role for gabapentin in preventing or treating pain following thoracic surgery?

A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether gabapentin, a commonly prescribed neuropathic analgesic and anticonvulsant, is safe and beneficial in patients with post-thoracotomy pain following thoracic surgery. Seventeen papers were identified using the search described below, and five papers presented the best evidence to reach conclusions regarding the issues of interest for this review.

Objectives: To measure the variation in activity parameters in patients with stroke over several days, and to assess whether patients with chronic stroke differ from each other in their achievement of ambulatory activity level.

Design: Descriptive study.

Methods: A total of 14 patients with chronic stroke wore 2 tri-axial accelerometers in their pockets for 7 consecutive days.

Dopamine from the brain promotes spinal motor neuron generation during development and adult regeneration.

Coordinated development of brain stem and spinal target neurons is pivotal for the emergence of a precisely functioning locomotor system. Signals that match the development of these far-apart regions of the central nervous system may be redeployed during spinal cord regeneration. Here we show that descending dopaminergic projections from the brain promote motor neuron generation at the expense of V2 interneurons in the developing zebrafish spinal cord by activating the D4a receptor, which acts on the hedgehog pathway.

Pseudohypoaldosteronism type 1: clinical features and management in infancy.

Unlabelled: Type 1 pseudohypoaldosteronism (PHA) is a rare heterogeneous group of disorders characterised by resistance to aldosterone action. There is resultant salt wasting in the neonatal period, with hyperkalaemia and metabolic acidosis. Only after results confirm isolated resistance to aldosterone can the diagnosis of type 1 PHA be confidently made.
