Background: Endothelial cells are the first and most damaged target cells during acute lung injury (ALI). Endothelial dysfunction increases pulmonary microvascular permeability, subsequently leading to pulmonary oedema and organ dysfunction; however, clinical treatments against microvascular permeability show poor efficacy. Herein, we aimed to explore the role of the Sigma-1 receptor (Sig-1R) in pulmonary microvascular permeability by constructing ALI animal and cell models, and further investigated the specific mechanisms.

Article Synopsis
  • - Sepsis-associated acute kidney injury (SAKI) is a serious condition in ICUs, leading to high rates of illness and death, and the role of Sirtuin 2 (SIRT2) in this context is not well understood.
  • - Inhibiting SIRT2 with the antagonist AGK2 improved survival rates in septic mice, reduced markers of kidney damage, and increased the formation of autophagic structures in kidney cells.
  • - The study indicates that targeting SIRT2 can enhance kidney autophagy, thereby offering a potential new therapeutic approach to treat SAKI.

Objective: To assess the efficacy and safety of visual rigid laryngoscopy and video laryngoscopy and to provide clinical information for developing a more suitable intubation tool for elderly patients.

Methods: In 75 consecutive elderly patients undergoing elective surgery in a single institution, tracheal intubation was randomly performed by 2 experienced anaesthesiologists using visual rigid laryngoscopy (Group I, n = 38) or video laryngoscopy (Group II, n = 37). The primary outcome was intubation time.

Background : Our previous studies have shown that ameliorating mitochondrial damage in renal tubular epithelial cells (RTECs) can alleviate septic acute kidney injury (SAKI). It is reported that AMPK phosphorylation (p-AMPK) could ameliorate mitochondrial damage in renal tissue and Sirtuin 5 (SIRT5) overexpression significantly enhanced the level of p-AMPK in bovine preadipocytes. However, the role of SIRT5-mediated phosphorylation of AMPK in SAKI needs to be clarified.

Objective: To evaluate the efficacy and safety of sintilimab combined with apatinib plus capecitabine in the treatment of unresectable hepatocellular carcinoma (HCC) to provide a more effective first-line treatment for patients with advanced HCC.

Methods: This open-label, prospective, phase II study included patients with unresectable HCC who did not receive systematic treatment. The patients were treated with sintilimab (200 mg, intravenous drip, once every 3 weeks) combined with apatinib (250 mg, oral administration, once a day) plus capecitabine (1000 mg/m, twice a day; after 2 weeks of oral administration, the drug was stopped for 1 week; course of treatment, 3 weeks).

Peptides that possess specific affinity to distinct crystal facets have been reported previously. However, their adsorption behavior in terms of the crystal sizes and shapes is less exploited. Herein, we isolate several phage clones that show the strong affinity to {100} of Pd at a neutral pH from the M13 phage library, and among them the phages that have shape selectivity to the cubic structure are identified by eliminating ones that bind randomly shaped Pd nanoparticles (NPs).

Highly efficient and robust chemical motors are expected for the application in microbots that can selectively swim toward targets and accomplish their tasks in sensing, labeling, and delivering. However, one of major issues for such development is that current artificial swimmers have difficulty controlling their directional motion toward targets like bacterial chemotaxis. To program synthetic motors with sensing capability for the target-directed motion, we need to develop swimmers whose motions are sensitive to chemical gradients in environments.

In cancer cells, the oncogenic mutant p53 (mtp53) protein is present at high levels and gain-of-function (GOF) activities with more expression of mtp53 proteins contribute to tumor growth and metastasis. Robust analytical approaches that probe the degree of metastasis of cancer cells in connection with the mtp53 activity will be extremely useful not only for establishing a better cancer prognosis but also understanding the fundamental mechanism of mtp53 oncogenic action. Here we assessed the influence of mtp53 in breast cancers to the mechanical property of breast cancer cells.

Pb-binding TAR-1 peptides (Ile-Ser-Leu-Leu-His-Ser-Thr) were covalently conjugated on a bolaamphiphile peptide nanotube substrate and the precursors of PbSe were incubated at room temperature. This resulted in the growth of highly crystalline PbSe nanocubes on this biomimetic cylindrical substrate. The growth mechanism to generate nanocubes occurs via the directed self-assembly of nanoparticles and then nanoparticle fusion.
