Unraveling calcium dysregulation and autoimmunity in immune mediated rippling muscle disease.

Rippling Muscle Disease (RMD) is a rare skeletal myopathy characterized by abnormal muscular excitability manifesting with wave-like muscle contractions and percussion-induced muscle mounding. Hereditary RMD is associated with caveolin-3 or cavin-1 mutations. Recently, we identified cavin 4 autoantibodies as a biomarker of immune-mediated RMD (iRMD), though the underlying disease-mechanisms remain poorly understood.

Chronic limb-threatening ischemia (CLTI) is the most severe manifestation of peripheral arterial disease (PAD) and imposes a significantly high burden due to its high risk of mortality and amputation. Revascularization is the first-line treatment for CLTI; however, the amputation rate remains high, and approximately one-third of patients are not eligible for this treatment. Therefore, there is an urgent need for more effective therapeutic strategies.

Diuretic drugs act on electrolyte transporters in the kidney to induce diuresis and are often used in chronic kidney disease (CKD), given that nephron loss creates a deficit in the ability to excrete dietary sodium, which promotes an increase in plasma volume. This rise in plasma volume is exacerbated by CKD-induced systemic and intra-renal activation of the renin-angiotensin-aldosterone-system, which further limits urinary sodium excretion. In the absence of a compensatory decrease in systemic vascular resistance, increases in plasma volume induced by sodium retention can manifest as a rise in systemic arterial blood pressure.

Grupo de Nutrición, Facultad de Salud, Universidad del Valle, Cali, Colombia.
Objective: The expansion of human activities in northern Colombia has increased human-snake encounters, particularly with venomous . Given the limited knowledge of systemic envenomation effects and previous studies focusing only on early murine symptoms, this investigation aimed to describe the time-course physiopathology of envenomation following intramuscular injection .
Methods: Venom was inoculated in the gastrocnemius muscles of Swiss Webster mice, and blood, urine, and tissue samples were taken at different times to evaluate lethality and biochemical markers of renal function and oxidative stress.
