Objectives: High sodium intake is a major risk factor for hypertension and renal diseases. Previous studies have shown that a suspension of ethanolic extract of Psidium guajava (guava) leaves (PsE) has antihypertensive effects in rats on a high-sodium diet (HSD), but some mechanisms to that remain unexplored. This study explored whether oral PsE treatment affects sodium handling by the intestine and alters the gut microbiome in HSD-fed rats.

Excessive sugar intake has been associated with the onset of several non-communicable chronic diseases seen in humans. Physical activity could affect sweet taste perception which may affect sugar intake. Therefore, it was investigated the chronic effects of swimming training on sucrose intake/preference, reactivity to sucrose taste, self-care in neurobehavioral stress, and the possible involvement of the vasopressin type V receptor in sucrose solution intake.

complex causes tuberculosis (TB), a disease that causes pulmonary inflammation but can also affect other tissues. Despite macrophages having a defined role in TB immunopathogenesis, other innate immune cells, such as neutrophils, are involved in this process. These cells have high phagocytic ability and a microbial-killing machine comprised of enzymes, antimicrobial peptides, and reactive oxygen species.

Sodium is the main cation present in the extracellular fluid. Sodium and water content in the body are responsible for volume and osmotic homeostasis through mechanisms involving sodium and water excretion and intake. When body sodium content decreases below the homeostatic threshold, a condition termed sodium deficiency, highly motivated sodium seeking, and intake occurs.

New Findings: What is the central question of this study? How does swimming exercise training impact hydro-electrolytic balance, renal function, sympathetic contribution to resting blood pressure and cerebrospinal fluid (CSF) [Na ] in rats fed a high-sodium diet from weaning? What is the main finding and its importance? An exercise-dependent reduction in blood pressure was associated with decreased CSF [Na ], sympathetically driven vasomotor tonus and renal fibrosis indicating that the anti-hypertensive effects of swimming training in rats fed a high-sodium diet might involve neurogenic mechanisms regulated by sodium levels in the CSF rather than changes in blood volume.

Abstract: High sodium intake is an important factor associated with hypertension. High-sodium intake with exercise training can modify homeostatic hydro-electrolytic balance, but the effects of this association are mostly unknown.

Physical training (ET) is important to restore the reflex sensitivity involved in controlling blood pressure in various diseases. Recent investigations have demonstrated an interaction between cardiopulmonary baroreceptors and arterial baroreflex during dynamic exercise. Considering that acute and chronic hemodynamic responses to swimming (SW) are different from the race (RUN), the objective of this study was to evaluate the effect of SW and RUN on baroreflex response before and after acute volume expansion in spontaneously hypertensive rats (SHR).

Article Synopsis
  • The study examined how a high sodium diet affects hypertension in male Wistar rats from weaning to adulthood, showing significant differences in blood pressure and kidney function compared to a regular sodium diet.
  • Rats on a high sodium diet had increased water intake, urine output, and sodium excretion, resulting in a 13.8% higher blood pressure; ganglionic blockade further lowered their blood pressure significantly.
  • The findings suggest that chronic salt intake leads to hypertension through neurogenic mechanisms, with alterations seen in central nervous system sodium and potassium levels, but no major changes in kidney structure or function.

There is evidence that diets rich in salt or simple sugars as fructose are associated with abnormalities in blood pressure regulation. However, the mechanisms underlying pathogenesis of salt- and fructose-induced kidney damage and/or consequent hypertension yet remain largely unexplored. Here, we tested the role of oxidative state as an essential factor along with high salt and fructose treatment in causing hypertension.
