Oncological safety of minimally invasive surgery in borderline ovarian tumor and ovarian cancer: a retrospective comparative study.

Objective: This study aimed to evaluate the oncological safety of laparoscopic surgery for patients with benign tumors who underwent laparoscopic surgery at our facility and were subsequently diagnosed with borderline ovarian tumors or ovarian cancer.

Methods: We conducted a retrospective review of 45 patients initially diagnosed with benign ovarian tumors who underwent laparoscopic surgery at our institution from January 2009 to April 2024.

Results: Postoperative pathological examination identified 32 cases of borderline ovarian tumors and 13 cases of ovarian cancer.

Preparation of a covalent organic framework-modified silica-gel composite for the effective adsorption of Pd(II), Zr(IV) and Mo(VI) from nitric acid solution.

In this study, a novel covalent organic framework-modified silica-gel composite (Si-COF) was synthesized for the adsorption of palladium [Pd(II)], zirconium [Zr(IV)], and molybdenum [Mo(VI)] from nitric acid solutions and its adsorption behaviors were systemically investigated under the effects of contact time, nitric acid concentration, solution temperature and others. The pseudo-second-order kinetic model governed the adsorption of these metal ions onto the Si-COF composite, and the Langmuir isotherm model well-matched with the experimental data, with maximum adsorption capacities of 0.588, 0.

A silyl porphyrin derivative conjugated with 6-deoxy-6-sulfo-α-d-glucopyranose functions as an efficient photosensitizer for photodynamic therapy.

We synthesized a new silyl porphyrin derivative conjugated with 6-deoxy-6-sulfo-α-d-glucopyranose (SGlc). Conjugation with SGlc improved A549 cellular uptake without significant changes in the photophysical and photochemical properties and subcellular localization. This improved cellular uptake led to enhanced photodynamic activity.

Natto extract inhibits infection caused by the Aujeszky's disease virus in mice.

Aujeszky's disease virus (ADV), also known as Suid alphaherpesvirus 1, which mainly infects swine, causes life-threatening neurological disorders. This disease is a serious global risk factor for economic losses in the swine industry. The development of new anti-ADV drugs is highly anticipated and required.
