Comparison of the effectiveness of 2 shockwave therapy protocols for the treatment of vascular erectile dysfunction: a randomized, multicenter, open-label, noninferiority, phase 4 clinical trial.

Background: Shockwave therapy is an optional adjuvant treatment for vascular erectile dysfunction (ED). There is variability in treatment protocols and challenges with patients adherence to the weekly protocol, which is the most commonly used.

Aim: This study aimed to evaluate the noninferiority of a monthly shockwave therapy protocol compared to the weekly protocol for treating vascular ED.

Global atmospheric methane uptake by upland tree woody surfaces.

Methane is an important greenhouse gas, but the role of trees in the methane budget remains uncertain. Although it has been shown that wetland and some upland trees can emit soil-derived methane at the stem base, it has also been suggested that upland trees can serve as a net sink for atmospheric methane. Here we examine in situ woody surface methane exchange of upland tropical, temperate and boreal forest trees.

Acute Interstitial Inflammation on Skin Biopsies and Positive Tissue Cultures in Cellulitis Patients Are Associated a Worse Prognosis.

Background: Cellulitis is a significant public health burden and lacks a gold standard for diagnosis. Up to 1/3 of patients are incorrectly diagnosed. The skin biopsy has been proposed as the gold standard.

Human pulmonary microvascular endothelial cell DDAH1-mediated nitric oxide production promotes pulmonary smooth muscle cell apoptosis in co-culture.

Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease in preterm infants, and pulmonary hypertension (PH) develops in 25%-40% of patients with BPD, increasing morbidity and mortality. BPD-PH is characterized by vasoconstriction and vascular remodeling. Nitric oxide (NO) is a pulmonary vasodilator and apoptotic mediator made in the pulmonary endothelium by NO synthase (eNOS).
