"Vacuum Assisted Closure" (VAC) is a noninvasive negative pressure healing process indicated in the treatment of chronic wounds associated with unfavourable local or systemic factors. It is indicated for the treatment of traumatic and/or surgical skin defects in order to accelerate the healing process. VAC is based on a simple technology of controlled depression of the lesion which healing process. It exerts a mechanical force on the tissues and attracts the wound edges centripetally. It induces an increased peripheral blood flow, improved local oxygenation and promotes angiogenesis and proliferation of good quality granulation tissue. Wound healing in a humid medium is complete or may require secondary surgical management (skin graft, flaps). The preferential indications for Vacuum Assisted Closure include pressure sores, leg ulcer, wounds with skin defects, burns, complications of surgical wounds and delayed healing.

The purpose of this study is to assess the safety and effectiveness of TiRobot-assisted treatment for femoral neck fractures, in comparison to traditional freehand treatment methods. Throughout the research process, we conducted an extensive literature search across numerous databases, including PubMed, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), CQVIP, and Wanfang. Based on the literature screening criteria, we selected six studies, encompassing 358 cases of femoral neck fracture patients, for this meta-analysis.

Objectives/hypothesis: Vocal fold (VF) injury and chronic inflammation can progress to scarring, which is notoriously difficult to treat. Human amniotic fluid (AF) has potential for VF wound healing in a rabbit model, and we hypothesized that AF would demonstrate wound healing properties superior to hyaluronic acid (HA) over time.

Migration is an essential characteristic of cells that occurs during many physiological and pathological processes. Astrocytes represent the most abundant cell type in the adult central nervous system (CNS), that play a crucial role in various functions such as guiding and supporting neuronal migration during development and maintaining brain homeostasis at adulthood. Astrocytes specifically synthesize and release endozepines, a family of regulatory peptides, including the octadecaneuropeptide (ODN).

Understanding how TiO2 interacts with CO2 at the molecular level is crucial in the CO2 reduction toward value-added energy sources. Here, we report in-situ observations of the CO2 activation process on the reduced TiO2(110) surface at room temperature using ambient pressure scanning tunneling microscopy. We found that oxygen vacancies (Vo) diffuse dynamically along the bridging oxygen (Obr) rows of the TiO2(110) surface under ambient CO2(g) environments.

Background: Tumor microenvironment (TME) plays a crucial role in tumor growth and metastasis. Exploring biomarkers that are significantly associated with TME can help guide individualized treatment of patients.
Methods: We analyzed the expression and survival of P4HB in pan-cancer through the TCGA database, and verified the protein level of P4HB by the HPA database.
