Characterisation of Platelet Releasate Proteome in Relapsing-Remitting Multiple Sclerosis Reveals Dysregulation of Inflammatory Signalling and Extracellular Vesicle Dynamics.

Purpose: Multiple Sclerosis is an inflammatory neurodegenerative disease characterised by blood-brain barrier dysfunction and leukocyte infiltration into the CNS. Platelets are best known for their contributions to haemostasis, however, upon activation, platelets release an abundance of soluble and vesicular-associated proteins, termed the platelet releasate (PR). This milieu contains numerous inflammatory and vasoactive proteins, that can attract leukocytes and alter endothelial permeability.

A comparison of risk factors for canine leptospirosis and seropositivity in New South Wales, Australia.

This study aimed to identify and compare risk factors associated with canine leptospirosis and Leptospira seropositivity in New South Wales, Australia. Seventy-nine canine cases of confirmed leptospirosis (clinical cases) and 16 healthy dogs seropositive to Leptospira (seropositive cases) were included in the study; these were separately compared to 394 healthy dogs seronegative to Leptospira (controls) in at-risk areas. A questionnaire investigated rat contact, stagnant water, dog park access and household number of dogs and cats.

Serovar Australis replaces serovar Copenhageni as the most common cause of canine leptospirosis in New South Wales, Australia.

Highly fatal canine leptospirosis emerged in urban Sydney dogs in 2017, and serovar Copenhageni, against which a registered monovalent vaccine is available, was predominant until 2020. This study was conducted to (1) determine serological characteristics of canine leptospirosis in New South Wales (NSW) between 2021 and 2023; (2) describe the geospatial distribution of leptospirosis; and (3) evaluate if clinicopathological abnormalities and outcome differ between the dominant infecting serovars, Copenhageni versus Australis. Cases were identified through referral or direct veterinarian contact and included if clinical and clinicopathological findings confirmed leptospirosis.

Estimating Young Children's Exposure to Food and Beverage Marketing on Mobile Devices.

Background: Food and beverage marketing drives poor diet quality and obesity risk among children. However, it is unknown how much young children are exposed to digital food and beverage marketing on mobile devices like tablets and smartphones.

Objectives: The objective of this study was to estimate how frequently young children, who are particularly vulnerable to advertising, view food and beverage marketing while using mobile devices.

Results from a Double-Blind, Randomized, Placebo-Controlled, Single-Dose, Crossover Trial of Lovastatin or Minocycline in Fragile X Syndrome.

Treatment studies in knockout rodent models have found that minocycline and lovastatin each improve synaptic, neurological, and behavioral functioning, and open-label chronic dosing studies in human patients with fragile X syndrome (FXS) have demonstrated modest clinical improvements. Findings from blinded studies are mixed, and there is a limited understanding of electrophysiological target engagement that would facilitate cross-species translational studies. Smaller-scale, acute (e.
