Polysaccharide-Containing Carboxymethyl Cellulose Bilayer Structure Membrane for Prevention of Postoperative Adhesion and Achilles Tendon Repair.

Postoperative tissue adhesion and poor tendon healing are major clinical problems associated with tendon surgery. To avoid postoperative adhesion and promote tendon healing, we developed and synthesized a membrane to wrap the surgical site after tendon suturing. The bilayer-structured porous membrane comprised an outer layer [1,4-butanediol diglycidyl ether cross-linked with carboxymethyl cellulose (CX)] and an inner layer [1,4-butanediol diglycidyl ether cross-linked with polysaccharides and carboxymethyl cellulose (CXB)].

Association between a maternal vegetarian diet during pregnancy and the occurrence of atopic dermatitis in children.

Background: Atopic dermatitis (AD) is rising globally, with genetics and environmental factors both playing crucial roles. Dietary habits during pregnancy are linked to children's allergic disease risk. However, limited studies have explored the association between maternal vegetarian diets during pregnancy and child AD.

Enhancing Zn Storage Performance by Constructing the Interfaces Between VO and Co-N-C Layers.

Vanadium oxides have aroused attention as cathode materials in aqueous zinc-ion batteries (AZIBs) due to their low cost and high safety. However, low ion diffusion and vanadium dissolution often lead to capacity decay and deteriorating stability during cycling. Herein, vanadium dioxides (VO) nanobelts are coated with a single-atom cobalt dispersed N-doped carbon (Co-N-C) layer via a facile calcination strategy to form Co-N-C layer coated VO nanobelts (VO@Co-N-C NBs) for cathodes in AZIBs.

Nanoscaled biphasic calcium phosphate modulates osteogenesis and attenuates LPS-induced inflammation.

Micron-scale structure biphasic calcium phosphate (BCP) materials have demonstrated promising clinical outcomes in the field of bone tissue repair. However, research on biphasic calcium phosphate materials at the nanoscale level remains limited. In this study, we synthesize granular-shaped biphasic calcium phosphate nanomaterials with multiple desirable characteristics, including negatively charged surfaces, non-cytotoxicity, and the capability to penetrate cells, using a nanogrinding dispersion process with a polymeric carboxylic acid as the dispersant.

Tumor suppressor p53 mediates interleukin-6 expression to enable cancer cell evasion of genotoxic stress.

The tumor suppressor p53 primarily functions as a mediator of DNA damage-induced cell death, thereby contributing to the efficacy of genotoxic anticancer therapeutics. Here, we show, on the contrary, that cancer cells can employ genotoxic stress-induced p53 to acquire treatment resistance through the production of the pleiotropic cytokine interleukin (IL)-6. Mechanistically, DNA damage, either repairable or irreparable, activates p53 and stimulates Caspase-2-mediated cleavage of its negative regulator mouse double minute 2 (MDM2) creating a positive feedback loop that leads to elevated p53 protein accumulation.

Emergency percutaneous nephrostomy versus emergency percutaneous nephrolithotomy in patients with sepsis associated with large uretero-pelvic junction stone impaction: a randomized controlled trial.

Introduction: A randomized trial was conducted prospectively to evaluate the efficacy, related complications, and convalescence of emergency percutaneous nephrolithotomy compared to percutaneous nephrostomy for decompression of the collecting system in cases of sepsis associated with large uretero-pelvic junction stone impaction.

Materials And Methods: The inclusion criteria included a WBC count of 10.000/mm3 or more and/or a temperature of 38°C or higher.

The association between skull bone fractures and outcomes in patients with severe traumatic brain injury.

Background: In traumatic brain injury (TBI), computed tomography (CT) provides a good assessment of anatomic pathologic findings and the prognostic value of CT characteristics has been well discussed. However, few studies have focused on skull bone fracture and its clinical prognostic importance. Hence, this study aims to evaluate the effects of skull bone fracture on patients with severe TBI admitted to the emergency unit.

A delta-doped quantum well system with additional modulation doping.

A delta-doped quantum well with additional modulation doping may have potential applications. Utilizing such a hybrid system, it is possible to experimentally realize an extremely high two-dimensional electron gas (2DEG) density without suffering inter-electronic-subband scattering. In this article, the authors report on transport measurements on a delta-doped quantum well system with extra modulation doping.

Laboratory risk indicator for necrotizing fasciitis score and the outcomes.

Background: Laboratory risk indicator for necrotizing fasciitis (LRINEC score) is a simple laboratory tool used to distinguish between necrotizing soft-tissue infections (NSTI) and other soft-tissue infections. A LRINEC score of > or =6 is considered as denoting a high risk of necrotizing fasciitis. A certain LRINEC score might also be associated with mortality and other outcomes of patients with NSTI.
