Transumbilical laparoendoscopic single-site surgery vs. multiport laparoscopic surgery for benign ovarian cysts: a retrospective cohort study.

Background: Transumbilical laparoendoscopic single-site surgery (TU-LESS) has gained increasing attention due to the potential to maximize the benefits of laparoscopic surgery. This study aimed to compare outcomes of TU-LESS and multiport laparoscopic surgery (MLS) for the treatment of benign ovarian cysts.

Methods: This retrospective cohort study included patients with benign ovarian cysts that were admitted to the Second Hospital of Hebei Medical University between September 2010 and September 2022.

Association between microplastics and the functionalities of human gut microbiome.

As an integral part of humans, the gut microbiome plays a significant role in the physiological and pathological processes of the host, and dysbiosis of the gut microbiome is linked to various diseases. The impact of microplastics on the diversity and composition of human gut microbiome has been reported previously. However, effects of microplastics on the functionality of the gut microbiome in humans have not been well studied.

5-Fluorouracil-methotrexate conjugate enhances the efficacy of 5-fluorouracil in colorectal cancer therapy.

To extend the short half-life of fluorouracil (Fu), enhance its tumor targeting, improve efficacy, and reduce side effects, providing a new approach for colorectal cancer treatment. Fluorouracil was hydroxylated and conjugated with methotrexate to form a 5-fluorouracil-methotrexate conjugate (MF). This was complexed with sulfobutyl ether-β-cyclodextrin (MF-SEBCD) using a stirring method to create an injectable formulation.

HMGA1 influence on iron-induced cell death in Tfh cells of SLE patients.

The autoimmune disorder known as Systemic Lupus Erythematosus (SLE) exhibits intricate features with abnormal immune responses leading to tissue injury. The generation of antibodies and the disruption of immune regulation heavily depend on the pivotal function of T follicular helper (Tfh) cells. Iron dysregulation is significant in autoimmune diseases, impacting immune cell function and disease progression.

Oncogenic PIK3CA corrupts growth factor signaling specificity.

Technical limitations have prevented understanding of how growth factor signals are encoded in distinct activity patterns of the phosphoinositide 3-kinase (PI3K)/AKT pathway, and how this is altered by oncogenic pathway mutations. We introduce a kinetic, single-cell framework for precise calculations of PI3K-specific information transfer for different growth factors. This features live-cell imaging of PI3K/AKT activity reporters and multiplexed CyTOF measurements of PI3K/AKT and RAS/ERK signaling markers over time.
