Article Synopsis
- Intestinal ischemia-reperfusion injury can lead to both large-scale (macrocirculatory) and small-scale (microcirculatory) blood flow failures, and the study aimed to test if combining a vasoconstrictor (norepinephrine) with a vasodilator (ilomedin) improves blood pressure and circulation after injury.
- The research was conducted on 21 pigs, with three groups receiving different treatments before and after a 2-hour induced small bowel ischemia followed by reperfusion, measuring various circulatory parameters and biomarkers.
- Results showed no significant differences in mean arterial pressure or cardiac index between the groups, but the combination therapy group had notably better microcirculation performance immediately after and two
Objective: Hyperoxia exposure leads to the development of lung injury and bronchial hyperreactivity (BHR) via involvement of nitric oxide (NO) pathway. We aimed at characterizing whether the stimulation of the NO pathway by sildenafil or vasoactive intestinal peptide (VIP) is able to prevent the hyperoxia-induced development of BHR. The respective roles of the preserved lung volume and alveolar architecture, the anti-inflammatory and anti-apoptotic potentials of these treatments in the diminished lung responsiveness were also characterized.

However, palpability of the spermatic vein and reflux in low grade or even questionable varicoceles can be difficult to assess without imaging modalities. This can be a common problem for all physicians treating hypofertile men to decide whether the varicele needs to be treated or not.

Methods: Biopsies were directed into hypervascularized (CDUS+) or hypovascularized (CDUS-) hypoechoic peripheral zone nodules (443 cases). When transrectal ultrasound (TRUS) was normal (148 cases), biopsies were directed into hypervascular area.
