Hypoglycemic effects of an aqueous extract of Bauhinia forficata on the salivary glands of diabetic mice.

The objective of this study was to evaluate the salivary glands in diabetic mice, analyzing alterations in the secretory epithelium and interactions with the stromal compartment acquired during a prolonged period of treatment with Bauhinia forficata extract. Female mice were divided into two groups: Nonobese diabetic (NOD) mice treated with Bauhinia forficata (I), and NOD mice not treated with the hypoglycemic agent (II). After treatment, the salivary glands were collected for analysis by transmitted and polarized light microscopy, complemented by three-dimensional analysis of these tissues. The results showed weight loss in animals of group II and weight recovery in treated animals. Glucose levels were elevated in group II, but declined in group I. In the two groups, the salivary glands were characterized by involution of the secretory epithelium, presence of an inflammatory infiltrate and an increase of extracellular fibrillar components. It can be concluded that treatment with Bauhinia forficata reduced glucose levels and contributed to weight recovery in treated animals. However, the observation of tissue destructuring and compromised epithelial-stromal interactions, with consequent impairment of glandular function, demonstrates that Bauhinia forficata exerts an effect on the recovery of body metabolism but this improvement does not influence in the tissue recovery.

Three-Dimensional Printing in Minimally Invasive Cardiac Surgery: Optimizing Surgical Planning and Education with Life-Like Models.

Over recent years, the surgical community has demonstrated a growing interest in imaging advancements that enable more detailed and accurate preoperative diagnoses. Alongside with traditional imaging methods, three-dimensional (3-D) printing emerged as an attractive tool to complement pathology assessment and surgical planning. Minimally invasive cardiac surgery, with its wide range of challenging procedures and innovative techniques, represents an ideal territory for testing its precision, efficacy, and clinical impact. This review summarizes the available literature on 3-D printing usefulness in minimally invasive cardiac surgery, illustrated with images from a selected surgical case. As data collected demonstrates, life-like models may be a valuable adjunct tool in surgical learning, preoperative planning, and simulation, potentially adding safety to the procedure and contributing to better outcomes.

Technical aspects of a totally endoscopic, robotic-assisted pericardial cyst resection.

A pericardial cyst is a rare mediastinal mass, often diagnosed as an incidental finding. Symptomatic patients or those with suspicion of malignancy may warrant surgical resection. In this video tutorial, we demonstrate the technical aspects of a totally endoscopic robotic-assisted pericardial cyst resection. This approach allows for definitive treatment through a safe procedure, with a small surgical wound, short in-hospital stay, a fast recovery, and almost no postoperative limitations.
