Pharmacokinetics and tolerability of single-dose enteral cannabidiol and cannabidiolic acid rich hemp in horses ().

The pharmacokinetics and tolerability of cannabinoids and their metabolites were determined in eight horses after enteral administration of a commercial CBD/CBDA-rich hemp oil product. Each horse was administered 2 mg/kg or 8 mg/kg CBD/CBDA or no treatment in a randomized cross-over design. Serial serum samples collected over 48 h were analyzed by high performance liquid chromatography with tandem mass spectrometry.

Connectome-driven neural inventory of a complete visual system.

Vision provides animals with detailed information about their surroundings, conveying diverse features such as color, form, and movement across the visual scene. Computing these parallel spatial features requires a large and diverse network of neurons, such that in animals as distant as flies and humans, visual regions comprise half the brain's volume. These visual brain regions often reveal remarkable structure-function relationships, with neurons organized along spatial maps with shapes that directly relate to their roles in visual processing.

Beyond the biomedical: an evaluation of the introduction of social gerontology into a postgraduate geriatric medicine education program.

Geriatric Medicine education tends to adopt a biomedical lens, despite the practice of Geriatric Medicine involving the comprehensive assessment of the functional, psychological, and social aspects of older people's lives. In this commentary, we describe the delivery of a Social Gerontology education program for Geriatric Medicine trainees in the Northwest of England. Education in Social Gerontology-a field that focuses on how social, cultural, economic, and environmental factors shape the lives of older adults-is thought to mitigate against ageism, a pervasive and multifaceted form of discrimination.

Current Concepts in Head and Neck Surgery.

This article is intended to "brush up" on the literature updates for the management of head and neck surgeries, particularly mandibulectomy and maxillectomy. Few new techniques have been described in the past decade in dental and oral oncological surgery. A tendency of developing more aggressive surgical strategies to treat complex oral tumors is evident from the recent veterinary literature and the emerging novel techniques for bone regeneration of maxillofacial defects.

Core Strategies to Increase the Uptake and Use of Potassium-Enriched Low-Sodium Salt.

Excess sodium consumption and insufficient potassium intake contribute to high blood pressure and thus increase the risk of heart disease and stroke. In low-sodium salt, a portion of the sodium in salt (the amount varies, typically ranging from 10 to 50%) is replaced with minerals such as potassium chloride. Low-sodium salt may be an effective, scalable, and sustainable approach to reduce sodium and therefore reduce blood pressure and cardiovascular disease at the population level.

OncoThreads: visualization of large-scale longitudinal cancer molecular data.

Motivation: Molecular profiling of patient tumors and liquid biopsies over time with next-generation sequencing technologies and new immuno-profile assays are becoming part of standard research and clinical practice. With the wealth of new longitudinal data, there is a critical need for visualizations for cancer researchers to explore and interpret temporal patterns not just in a single patient but across cohorts.

Results: To address this need we developed OncoThreads, a tool for the visualization of longitudinal clinical and cancer genomics and other molecular data in patient cohorts.

Evaluation of the effect of ultrasound guidance on the accuracy of intercostal nerve injection: a canine cadaveric study.

Objective: To develop an ultrasound-guided approach to intercostal nerve injection and to compare the success rate of intercostal nerve injections using blind or ultrasound-guided technique in canine cadavers.

Study Design: Prospective, randomized, descriptive, experimental anatomic study.

Animals: A total of 14 mid-sized adult canine cadavers.

Comparison between two approaches for the transversus abdominis plane block in canine cadavers.

Objective: To compare the dye distribution following either two lateral abdominal or one lateral abdominal and one subcostal ultrasound-guided transversus abdominis plane (TAP) injections of a clinically relevant volume of dye solution in dogs.

Study Design: Randomized cadaveric study.

Animals: A total of eight canine cadavers.

Bioenergetics underlying single-cell migration on aligned nanofiber scaffolds.

Cell migration is centrally involved in a myriad of physiological processes, including morphogenesis, wound healing, tissue repair, and metastatic growth. The bioenergetics that underlie migratory behavior are not fully understood, in part because of variations in cell culture media and utilization of experimental cell culture systems that do not model physiological connective extracellular fibrous networks. In this study, we evaluated the bioenergetics of C2C12 myoblast migration and force production on fibronectin-coated nanofiber scaffolds of controlled diameter and alignment, fabricated using a nonelectrospinning spinneret-based tunable engineered parameters (STEP) platform.

Common gut microbial metabolites of dietary flavonoids exert potent protective activities in β-cells and skeletal muscle cells.

Flavonoids are dietary compounds with potential anti-diabetes activities. Many flavonoids have poor bioavailability and thus low circulating concentrations. Unabsorbed flavonoids are metabolized by the gut microbiota to smaller metabolites, which are more bioavailable than their precursors.

A small-scale air-cathode microbial fuel cell for on-line monitoring of water quality.

The heavy use of chemicals for agricultural, industrial and domestic purposes has increased the risk of freshwater contamination worldwide. Consequently, the demand for efficient new analytical tools for on-line and on-site water quality monitoring has become particularly urgent. In this study, a small-scale single chamber air-cathode microbial fuel cell (SCMFC), fabricated by rapid prototyping layer-by-layer 3D printing, was tested as a biosensor for continuous water quality monitoring.

Assembly of the TgrB1-TgrC1 cell adhesion complex during Dictyostelium discoideum development.

In Dictyostelium discoideum, TgrB1 and TgrC1 are partners of a heterophilic cell-adhesion system. To investigate its assembly process, the split GFP complementation assay was used to track the oligomeric status of both proteins. The ability of TgrC1 to form cis-homodimers spontaneously was demonstrated by fluorescence complementation studies and confirmed by chemical cross-linking.

Platypnoea-orthodeoxia in an elderly man with patent foramen ovale and dilated ascending aorta.

We report the case of an 85-year-old male with platypnoea-orthodeoxia associated with patent foramen ovale (PFO) and ectatic ascending aorta, in the absence of any significant pulmonary pathology.

14-3-3σ and p63 play opposing roles in epidermal tumorigenesis.

14-3-3σ plays a regulatory role in epidermal epithelial differentiation and loss of 14-3-3σ leads to increased proliferation and impaired differentiation. A tumor suppressor function for 14-3-3σ has been proposed based on the fact that some epithelial-derived tumors lose 14-3-3σ expression. p63, a p53 family member, is a master regulator of epidermal epithelial proliferation and differentiation and is necessary for the epidermal development.

Regulation of spatiotemporal expression of cell-cell adhesion molecules during development of Dictyostelium discoideum.

The social amoeba Dictyostelium discoideum is a simple but powerful model organism for the study of cell-cell adhesion molecules and their role in morphogenesis during development. Three adhesive systems have been characterized and studied in detail. The spatiotemporal expression of these adhesion proteins is stringently regulated, often coinciding with major shifts in the morphological complexity of development.

Replication factory activation can be decoupled from the replication timing program by modulating Cdk levels.

In the metazoan replication timing program, clusters of replication origins located in different subchromosomal domains fire at different times during S phase. We have used Xenopus laevis egg extracts to drive an accelerated replication timing program in mammalian nuclei. Although replicative stress caused checkpoint-induced slowing of the timing program, inhibition of checkpoint kinases in an unperturbed S phase did not accelerate it.

Training in elder abuse: the experience of higher specialist trainees in Geriatric Medicine in the UK.

Little is known about elder abuse training in post-graduate medical education in the United Kingdom. A questionnaire survey was conducted among Specialist Registrars (SpRs) in Geriatric Medicine attending a single training day within five UK Post-graduate Deaneries to assess self-report experience of elder abuse training during their post-graduate medical education. The questionnaire included quantity, quality and self-report confidence in dealing with elder abuse issues.
