Background: Low-frequency sinusoidal galvanic vestibular stimulation (sGVS) can induce perceptions of sway and nausea through entraining vestibular afferent firing to the sinusoidal stimulus. As recently shown, concurrent dorsolateral prefrontal cortex (dlPFC) stimulation via transcranial alternating current stimulation (tACS) greatly attenuates these vestibular perceptions.

Objective: Given that both vestibular afferents and dlPFC efferents project to the insular cortex, it was reasoned that the insula is the most likely area for the top-down inhibitory interaction to take place.

Background And Hypothesis: Recent advances in membranous nephropathy treatment have focused on B cell depletion, which is incompletely effective, potentially due to persistent autoantibody-producing plasma cells or alternative pathways of injury. T cell costimulatory blockade (cytotoxic-T-lymphocyte-associated antigen 4 (CTLA4)-Ig) to prevent T cell-dependent B cell activation and short-course proteasome inhibition (bortezomib) to deplete plasma cells may represent a complementary form of treatment.

Methods: Lewis rats were immunized with Fx1A and complete Freund's adjuvant (CFA) to induce experimental membranous nephropathy (Heymann nephritis or HN) and treated with CTLA4-Ig alone or CTLA4-Ig plus a short-course of bortezomib.

Background: Genetic kidney disease (GKD) significantly affects the community and is responsible for a notable portion of adult kidney disease cases and about half of cases in paediatric patients. It substantially impacts the quality of life and life expectancy for affected children and adults across all stages of kidney disease. Precise genetic diagnosis in GKD promises to improve patient outcomes, provide access to targeted treatments, and reduce the disease burden for individuals, families, and healthcare systems.

Transcranial magnetic stimulation (TMS) is applied both in research settings and clinically, notably in treating depression through the dorsolateral prefrontal cortex (dlPFC). We have recently shown that transcranial alternating current stimulation of the dlPFC partially entrains muscle sympathetic nerve activity (MSNA) to the stimulus. We, therefore, aimed to further explore the sympathetic properties of the dlPFC, hypothesizing that single-pulse TMS could generate de novo MSNA bursts.

Conflicts of interest (COIs) have the potential to create bias in research, policy and practice. Although disclosure cannot fully protect individuals and public policy from vested interests, it is an important step to support trust in scientific and public discourse, and transparency in decision-making. However, COIs are often unreported, underreported or difficult to identify.

Background: Despite deleterious biomechanics associated with injury, particularly as it pertains to load carriage, there is limited research on the association between physical demands and variables captured with wearable sensors. While inertial measurement units (IMUs) can be used as surrogate measures of ground reaction force (GRF) variables, it is unclear if these data are sensitive to military-specific task demands.

Research Question: Can wearable sensors characterise physical load and demands placed on individuals in different load, speed and grade conditions?

Methods: Data were collected on 20 individuals who were self-reportedly free from current injury, recreationally active, and capable of donning 23 kg in the form of a weighted vest.
