A recent overview of the application of emerging extraction medium-based sample preparation for the determination of aflatoxins and their precursors in food samples.

Food safety problem caused by aflatoxins (AFs) has become a major concern worldwide. However, due to the complexity of food matrices and the low concentration of analytes, the accurate and sensitive determination of AFs and their precursors in the biosynthetic pathway is extremely challenging, so the development of efficient sample preparation techniques has been urgently required. This paper reviews the recent advances in sample preparation based on some emerging extraction media for the determination of AFs and their precursors in different food samples, including ionic liquids (ILs) and IL-based composites, metal-organic frameworks (MOFs) and covalent organic frameworks (COFs).

Conductive hyaluronic acid/phytanic acid hydrogel to deliver recombinant human amelogenin for diabetic wound repair.

Diabetic wounds present a considerable challenge in modern medicine due to their prolonged healing process, driven by sustained inflammation and impaired vascular regeneration. This study introduces a novel hydrogel network through osmosis, utilizing hyaluronic acid (HA) and phytic acid (PA) for their anti-inflammatory and antioxidant properties, respectively. By incorporating recombinant Human Amelogenin (rhAM), known for its angiogenic potential, we aimed to develop the HA-PA-rhAM hydrogel to enhance wound healing in diabetic rats.

Comparison the Cosmetic Outcome of the Triangular Flap Insertion Versus Direct Linear Resection in Correction of Dog Ear Deformities on the Face-A Prospective and Randomized Controlled Trial.

Background: Compared with direct linear resection, the triangular flap insertion method is a correction method that purportedly reduces the incision tension of dog ears deformity. Randomized clinical trials comparing these 2 methods seem to be limited or absent.

Objective: A randomized study was planned to compare the cosmetic effect and scar in the defect area between the triangular flap insertion method and direct linear resection in the repair of dog ear deformities after the suture of the facial circular defect.

A nanoparticle-based wireless deep brain stimulation system that reverses Parkinson's disease.

Deep brain stimulation technology enables the neural modulation with precise spatial control but requires permanent implantation of conduits. Here, we describe a photothermal wireless deep brain stimulation nanosystem capable of eliminating α-synuclein aggregates and restoring degenerated dopamine neurons in the substantia nigra to treat Parkinson's disease. This nanosystem (ATB NPs) consists of gold nanoshell, an antibody against the heat-sensitive transient receptor potential vanilloid family member 1 (TRPV1), and β-synuclein (β-syn) peptides with a near infrared-responsive linker.

Risk factors for the occurrence of arytenoid dislocation after major abdominal surgery: A retrospective study.

The incidence of arytenoid dislocation in abdominal surgery is relatively high, the cause is unknown, and it has not received sufficient attention. To identify the risk factors of arytenoid dislocation after abdominal surgery, and to establish a clinical prediction model based on relevant clinicopathological characteristics. We retrospectively collected the clinical data of 50 patients with arytenoid dislocation (AD) and 200 patients without AD after abdominal surgery with general anesthetic tracheal intubation in our Hospital from January 2013 to December 2019.
