Genomic and Metabolomic Analyses of with Enhanced ε-Poly-l-lysine Production Through Adaptive Laboratory Evolution.

ε-poly-l-lysine (ε-PL), a natural food preservative, has garnered widespread attention. It is mainly produced by , but the production by wild-type strains fails to meet the demands of industrialization. To address this issue, adaptive laboratory evolution (ALE) was successfully employed in this study, subjecting CICC 11022 to environmental stresses such as acidic pH and antibiotics (rifampicin, gentamicin, and streptomycin).

[Clinical efficacy of open reduction and internal fixation with plates versus minimally invasive Kirschner wire fixation for osteoporotic Colles' fractures].

Objective: To compare the short-term clinical efficacy and safety of closed reduction with Kirschner wire fixation versus open reduction with plate fixation for treating osteoporotic Colles' fractures in middle-aged and elderly patients.

Methods: Between January 2018 and January 2023, 119 patients with Colles fractures were retrospectively analyzed, including 39 males and 80 females, aged from 48 to 74 years old with an average of(60.58±6.

Dedicator of Cytokinesis 2 regulates cytoskeletal actin dynamics and is essential for platelet biogenesis and functions.

Aims: Dedicator of Cytokinesis 2 (DOCK2), a member of the DOCK family of Guanine nucleotide exchange factors that specifically act on the Rho GTPases including Rac and Cdc42, plays pivotal roles in the regulation of leukocyte homeostasis. However, its functions in platelets remain unknown.

Methods And Results: Using mice with genetic deficiency of DOCK2 (Dock2-/-), we showed that Dock2-/-mice exhibited a macrothrombocytopenic phenotype characterized as decreased platelet count and enlarged platelet size by transmission electron microscopy.

Dual-modal radiomics ultrasound model to diagnose cervical lymph node metastases of differentiated thyroid carcinoma: a two-center study.

Objectives: To establish and validate a dual-modal radiomics nomogram from grayscale ultrasound and color doppler flow imaging (CDFI) of cervical lymph nodes (LNs), aiming to improve the diagnostic accuracy of metastatic LNs in differentiated thyroid carcinoma (DTC).

Methods: DTC patients with suspected cervical LNs in two medical centers were retrospectively enrolled. Pathological results were set as gold standard.

MYBL2 promotes proliferation of clear cell renal cell carcinoma by regulating TOP2A and activating AKT/mTOR signaling pathway.

Renal cell carcinoma (RCC) is one of the most common malignancies in the urinary system, and clear cell renal cell carcinoma (ccRCC) is the most common subtype. MYBL2 has been reported to be overexpressed in various tumors and associated with poor prognosis in patients, but its biological role in ccRCC remains unclear. In this study, we investigated the mRNA and protein expression levels of MYBL2 in ccRCC samples and evaluated the prognostic value of MYBL2 using TCGA dataset.
