Efficiency and safety of microvascular anastomotic coupler for wrist revascularization in traumatic injuries.

Introduction: Effective vascular anastomosis is crucial for successful hand surgery, particularly in traumatic injuries where rapid restoration of blood flow is essential. The Synovis microvascular anastomotic coupler system presents a novel approach by potentially offering faster and more reliable outcomes than traditional suturing methods. This study was conducted to assess the effectiveness and safety of the Synovis coupler for microvascular anastomoses in the wrist, evaluating anastomosis time, patency rates, and complication rates.

In vitro and in silico antioxidant and α-glucosidase inhibitory potential of compounds isolated from .

Nine compounds including a new one, garcichaudiic acid (), were isolated from the bark of and their structures were characterized mainly by 1 D and 2 D NMR experiments. The antioxidant capacity of the isolated compounds was determined using DPPH radical scavenging assay and the anti-hyperglycemic activity was assessed by measuring the inhibitory effect against α-glucosidase. Among them, compound showed higher antioxidant activity than the positive control, ascorbic acid, while both compounds and exhibited more significant α-glucosidase inhibitory activity than the reference drug acarbose.

Two new antidiabetic xanthones from the twigs of .

Two new xanthones, oblongixanthones I () and J (), and seven known compounds (-), were isolated from an EtOAc extract of the twigs of . Their structures were elucidated using spectroscopic methods, mainly 1 D and 2 D NMR. The antidiabetic effects of the two new compounds were evaluated using α-glucosidase and PTP1B inhibition assays.

Triterpenoids from the bark of .

Two new triterpenoids, entanolide () and methyl 3,4-secotirucalla-23-oxo-4(28),7,24-trien-21-al-3-oate (), together with nine known compounds (), were isolated from the bark of . Their structures were elucidated based on spectroscopic analyses, mainly 1 D and 2 D NMR spectral data. Compounds - and were evaluated for their cytotoxicity against HepG2 cells, and compounds exhibited weak activities.

Antioxidant and Antimicrobial Activities of the Extracts from Different Species.

Background: is a large genus which has promising bioactivities. However, the properties of many species have not been investigated thoroughly.

Aim: To determine the antioxidant and antimicrobial capabilities of the extracts from different species.

Cytotoxic limonoids from the bark of Walsura cochinchinensis.

Three new limonoids, walsucochinones A-C (1-3), along with eight known compounds, were isolated from an ethyl acetate extract of the bark of Walsura cochinchinensis. Their structures were determined using spectroscopic techniques, mainly 1-D and 2-D NMR. The ethyl acetate extract showed cytotoxic activity against MCF-7 human breast cancer cells and cytotoxicity of the isolated compounds were evaluated in vitro using the SRB assay.

Complex transposition repair with aortic arch hypoplasia: a simple technique.

A modified technique of interdigitating aortic arch reconstruction was used successfully to treat 8 patients with complex congenital heart disease including transposition of the great arteries, ventricular septal defect, or Taussig-Bing anomalies combined with aortic arch hypoplasia and coarctation of the aorta, without the need for homograft tissue.
