Summary: Pulmonary arterial hypertension (PAH) is characterized by elevated arterial pressure and vascular resistance. PAH may cause alterations in the microcirculation of several organs, including the kidney, liver, brain, and testes. This study investigated the impact of PAH on testicular morphology and function and found that PAH has deleterious effects on these parameters. However, resistance exercise training (RT) was shown to attenuate the negative effects of PAH on testicular parameters and improve testosterone levels.

Summary: Systemic sclerosis is an autoimmune disorder that affects the connective tissue and causes skin thickening and complications in the internal organs. Pulmonary involvement, including pulmonary arterial hypertension and interstitial lung disease, is the main cause of morbidity and mortality in scleroderma patients. Current treatment options are not specific to pulmonary involvement in scleroderma, and patients with pulmonary arterial hypertension in this population tend to have worse outcomes and lower response to therapy compared to other forms of Group I pulmonary hypertension.

Summary: The study compared the consequences of single and triple testicular biopsies in pubertal rats using histological and immunohistochemical analysis. The results showed that a single biopsy had minimal effects on overall fertility, while triple biopsies caused more significant histological and immunohistochemical consequences without significantly impacting overall fertility. Sperm analysis demonstrated that both single and triple biopsies had no significant effect on sperm count, motility, and morphology.

Summary: This study found that improving gut microbiota can significantly improve semen quality and male fertility in T1D patients. This is achieved through the production of specific fatty acids and the improvement of spleen and liver functions, which further promote a conducive environment for spermatogenesis.

Summary: Antiangiogenic therapies such as TKI and direct anti-VEGF monoclonal antibodies are increasingly used in the treatment of solid tumors, but they can lead to hypertension. This study evaluated the effects of these drugs on retinal arterioles and capillary density, finding that while they may require increased antihypertensive treatment, microvascular structure can be partially preserved under adequate blood pressure control.

Summary: This study compared the characteristics and survival rates of patients with systemic sclerosis-associated pulmonary hypertension (SSc-PH) between the last two decades. The results showed that the transplant-free survival rate has significantly improved for patients with group 1 disease over the past decade, possibly due to earlier detection and better therapeutic management. In contrast, patients with group 2 or 3 disease continue to have a poor prognosis.

Summary: This study investigated the effects of thymoquinone on the testes after exposure to cyclophosphamide. The results showed that cyclophosphamide exposure caused functional and structural changes in the testes, but thymoquinone intervention was able to reverse these effects, suggesting a potential protective role.

Summary: Systemic arterial hypertension is a complex disease characterized by accelerated vascular aging and high cardiovascular morbidity and mortality. Recent evidence has shown the involvement of epigenetic signals in maladaptive vascular remodeling, sympathetic activation, and cardiometabolic alterations, all of which contribute to the development of hypertension. These epigenetic changes have long-lasting effects on gene regulation and are not easily reversible.

Summary: Inflammation plays a significant role in the pathogenesis of PAH. The study found that PAH induced by MCT progresses from an acute inflammatory phase to a chronic inflammatory phase, with changes in pro-inflammatory cytokines and macrophage ratios in the lung. The PI3K/Akt signaling pathway is also related to the progression of PAH and inflammation characteristics induced by MCT.

Summary: Research on varicocele mechanisms using animal models, particularly rats, is crucial due to ethical restrictions on human tissue study designs. Inducing varicocele in rats through surgical techniques provides insights into the pathophysiology, allowing for the development of new therapeutic approaches. Animal models also aid in exploring antioxidant and anti-inflammatory agents to address varicocele conditions, with a focus on the newly uncovered inflammasome complex's potential role in the disease's pathophysiology.

Summary: The placenta is a temporary organ that plays critical roles at the maternal-fetal interface. Its normal development and function depend on hormonal signaling pathways, which also make it vulnerable to endocrine disrupting chemicals. New placental models have been developed to assess and prevent developmental toxic harm caused by these chemicals. This review focuses on discussing the newest in vitro models for understanding the maternal-fetal interface and predicting placental development, physiology, and dysfunction.

Summary: During the past decades, numerous factors influencing male infertility disease have been extensively studied. The role of inflammation in some major infertility-related conditions, such as varicocele, spinal cord injury, and obesity, has been investigated. Inflammation is the immune system's primary response to infection or cell damage, characterized by the release of inflammatory cytokines when homeostasis is disrupted. The activation of inflammasome, an important multiprotein complex, by pathogen-associated or damage-associated molecular patterns plays a crucial role in pro-inflammatory cytokine release. Although the involvement of inflammasome in male infertility has received recent attention, its potential as a target for drug therapy is promising. This review aims to provide insights into the activation of inflammasome complex, its implications in various male infertility conditions, and its localization in the male reproductive tract.

Summary: The anti-obesity hormones T3 and irisin have been found to stimulate thermogenesis and energy consumption, while reducing lipid accumulation. This study investigated their effects on the purinergic signaling pathway in adipocytes, and found that T3 and irisin differentially regulate the transcription of purinergic signaling markers. These findings may offer new insights into the treatment of obesity and related metabolic disorders.

Summary: Testicular torsion is a condition where the testis rotates around its longitudinal axis and twists the spermatic cord, causing a decrease in blood flow and perfusion of testicular tissue. Surgical intervention (testicular detorsion) is the recommended treatment option to prevent recurrence. Possible side effects include reperfusion injury, endothelial cell injury, microcirculation disturbances, and germ cell loss.

Summary: Sepsis is a serious systemic disease that affects multiple organs, including the brain. The brain's condition, known as sepsis-associated encephalopathy (SAE), can cause acute and chronic symptoms. Acute symptoms include delirium, while chronic symptoms include cognitive impairment, locomotor dysfunction, and mood disorders such as depression. The pathophysiology of SAE involves systemic and local actions.

This review focuses on the enhanced vascular permeability in the lungs of COVID-19 patients, which plays a crucial role in the morbidity and mortality caused by coronaviruses. The dysregulated vascular permeability is a potential target for both new and existing drugs.

Summary: Uncontrolled vasodilation is responsible for hypotension in advanced stages of sepsis, but the mechanisms of hypotension in earlier stages are unclear. This study found that early hypotension following bacterial lipopolysaccharide injection is caused by a decrease in vascular resistance while arterioles are still responsive. The prioritization of local blood flow regulation over brain-driven pressure regulation may underlie the development of early hypotension.
