In this study, dermoscopic examination of COVID-19 patients revealed significant microvascular changes in the proximal nailfold, such as avascular areas and disorganized capillary architecture, compared to healthy controls, with some regression of these changes observed over time.

New drugs like clonidine and prazosin show promise for treating high blood pressure despite some side effects.

This case report describes a 22-year-old woman whose initial manifestation of systemic lupus erythematosus was vision-threatening vaso-occlusive retinopathy, highlighting the need for early identification and multidisciplinary treatment.

Minoxidil effectively lowers blood pressure in patients with resistant hypertension.

This case report describes a patient with systemic lupus erythematosus who developed leukocytoclastic vasculitis, suggesting this skin condition may be related to SLE exacerbation.

In this study, testosterone-induced alopecia in male rats led to significant thinning and follicular degeneration, but treatment with adipose-derived stromal vascular fraction cells markedly improved these histological changes, suggesting a potential role in hair follicle regeneration.

In this study, researchers observed that in a limb ischemia model, vascular transplants preserved for 3 days had better recovery from ischemia-reperfusion injury compared to those preserved for 7 days, with less tissue edema and necrosis.

This study suggests that women with alopecia have decreased microcirculation oscillations, which may imply neuroinflammation as a factor in the disease's pathogenesis.

This study found that combining a single SVF injection with PRP sessions did not significantly enhance hair growth outcomes compared to PRP injections alone in patients with androgenetic alopecia.

In this case report, the authors describe a child and his mother with a heterozygous STING variant linked to SAVI, who exhibited atypical disease courses and varying organ involvement, underlining the diverse clinical manifestations of SAVI.

This study observed that in spontaneously hypertensive rats, testosterone's effects on endothelium-dependent vasodilation involved reduced nitric oxide levels, increased oxidative stress, and greater reliance on endothelium-dependent hyperpolarization, with variations in these responses noted when testosterone was combined with either anastrozole or finasteride.

In this study, researchers observed that blood vessel maturation in mice involves neonatal endothelial cells expanding the capillary network through vessel regression and angiogenesis, with adult cells later maintaining stability and repair through specific signaling pathways.

This case study highlights the complexity of managing PCOS and its symptoms in transmen, suggesting hormonal fluctuations may lead to symptomatic relief with low dose estradiol.

This case series reported good hair growth results in three androgenic alopecia patients treated with a combination of autologous platelet-rich plasma and stromal vascular fraction cells.

This study reports that a single injection of stromal vascular fraction (SVF) cells into the scalp of patients with androgenetic alopecia significantly increased hair density and thickness within 3 to 6 months, with no observed side effects.

The treatment showed promising hair growth results but needs more research.

Processed fat, SVF, and PRP are safe and effective for facial rejuvenation and hair growth.

Propylthiouracil, a thyroid medication, can cause skin blood clots and immune-related blood vessel inflammation.

In this study, men with persistent sexual dysfunction after stopping finasteride showed significant vascular, neurologic, and hormonal abnormalities, with severe erectile dysfunction being common.

This study describes a case series where combining PRP and stromal vascular fraction cells for androgenic alopecia led to denser hair growth and improved hair quality in three patients.

This study found that testosterone modulates vascular cell behavior through direct actions that do not rely on its conversion to estradiol.

Minoxidil can cause heart muscle damage in dogs.

This review examines the evolving understanding of lymphatic vessel development, emphasizing new cellular mechanisms and lineage diversity, while discussing experimental methods and identifying key knowledge gaps.

This review summarizes that polyesters hold promise for vascular tissue engineering due to their mechanical properties and biodegradability, but optimizing their use in repairing damaged blood vessels remains challenging due to the complexity of vascular tissues.

This review discusses the biofunctionalization of hydrogel scaffolds for vascular tissue regeneration and reports promising results from in vivo studies, such as improved angiogenesis and healing in pressure ulcers when using specific peptides.

This review discusses the advantages and progress of chitosan hydrogels in vascular regeneration for tissue engineering scaffolds, highlighting modifications to enhance their application and exploring future prospects.

This study found that finasteride may reduce inappropriate sexual behaviors in geriatric patients with vascular dementia and benign prostate hyperplasia without serious side effects, though some patients required additional medications.
