This is the first arm of a two prong study conducted to learn two different aspects of vasovasostomy in dog vas deferens using the milliwatt carbon dioxide laser. The first study involved the evaluation of patency without collection of sperm. Six dogs were evaluated and all underwent vasectomy and subsequently had vasovasostomies performed between 4 and 12 weeks utilizing two approximating sutures and welding with the milliwatt carbon dioxide laser. Metal clips were used for both X-ray analysis and localization of the vasovasostomy site. In this investigation a vasogram was performed. Dogs were sacrificed at 4, 6, and 8 weeks postvasovasostomy. The vasovasostomy specimens were studied with electron microscopy and histological evaluation. The vasovasostomy was completed in under 120 minutes using this laser-assisted technique and was found to be a viable and promising technique for vasovasostomy.

A high fraction of inspired oxygen does not mitigate atelectasis-induced lung tissue hypoxia or injury in experimental acute respiratory distress syndrome.

Although alveolar hyperoxia exacerbates lung injury, clinical studies have failed to demonstrate the beneficial effects of lowering the fraction of inspired oxygen (FO) in patients with acute respiratory distress syndrome (ARDS). Atelectasis, which is commonly observed in ARDS, not only leads to hypoxemia but also contributes to lung injury through hypoxia-induced alveolar tissue inflammation. Therefore, it is possible that excessively low FO may enhance hypoxia-induced inflammation in atelectasis, and raising FO to an appropriate level may be a reasonable strategy for its mitigation.

Background: Sepsis-associated encephalopathy (SAE) may be worsened by early systemic insults. We aimed to investigate the association of early systemic insults with outcomes of critically ill patients with severe SAE.
Methods: We performed a retrospective analysis using data from the French OUTCOMEREA prospective multicenter database.

Tea (Camellia oleifera Abel) seed oil (TSO) has antioxidant and pharmacological properties. In this study, TSO was obtained from tea seeds by subcritical n-butane extraction (SBE), which is an environmentally friendly method. The oil yield, quality characteristics, and chemical composition of the extracted TSO were compared with those of oils obtained by supercritical carbon dioxide extraction (SCDE) and conventional cold pressing (CP).

Background: Aeromedical transfer of patients with ischemic stroke to access hyperacute stroke treatment is becoming increasingly common. Little is known about how rapid changes of altitude and atmospheric pressure can impact cerebral perfusion and ischemic burden. In patients with ischemic stroke, there is a theoretical possibility that this physiologic response of hypoxia-driven hyperventilation at higher altitude can lead to a relative drop in PaCO2.
