Is identification and dissection of the external laryngeal nerve necessary during thyroidectomy? A prospective study.

Background: Compared to the recurrent laryngeal nerve, the EBSLN (or external laryngeal nerve) is less studied in terms of its course and relationship with the thyroid gland. This is a prospective intraoperative study designed to identify the anatomical variations of the EBSLN in relation to the IPC, the superior thyroid pedicle, and the point where the nerve crosses the STA. Additionally, the study aims to propose a technical procedure for its preservation.

Giant duodenal lipoma: an unusual cause of gastrointestinal bleeding (a case report).

Duodenal lipoma is a rare location of visceral lipomas, most are found incidentally via endoscopy or surgery and usually are asymptomatic. We report the case of a 58-year-old patient with an active bleeding duodenal lipoma. Although endoscopic treatment was scheduled initially, surgical intervention ultimately was indicated due to large size of tumor.

The In Vivo Antidiabetic Activity of Nigella sativa Is Mediated through Activation of the AMPK Pathway and Increased Muscle Glut4 Content.

The antidiabetic effect of N. sativa seed ethanol extract (NSE) was assessed in Meriones shawi after development of diabetes. Meriones shawi were divided randomly into four groups: normal control, diabetic control, diabetic treated with NSE (2 g eq plant/kg) or with metformin (300 mg/kg) positive control, both administered by daily intragastric gavage for 4 weeks.

The petroleum ether extract of Nigella sativa exerts lipid-lowering and insulin-sensitizing actions in the rat.

We studied the effect of a 4-week intragastric gavage with a petroleum ether extract of Nigella sativa seeds on blood glucose, insulin and lipids in the normal rat. Petroleum ether extract caused a 25% reduction in food intake that translated into a transient weight loss. No sign of toxicity of the plant could be seen in vivo or in vitro.
