Predictive performance of the variation rate of the driving pressure on the outcome of invasive mechanical ventilation in patients with acute respiratory distress syndrome.

Purpose: To assess the value of the driving pressure variation rate (ΔP%) in predicting the outcome of weaning from invasive mechanical ventilation in patients with acute respiratory distress syndrome.

Methods: In this case-control study, a total of 35 patients with moderate-severe acute respiratory distress syndrome were admitted to the intensive care unit between January 2022 and December 2022 and received invasive mechanical ventilation for at least 48 h were enrolled. Patients were divided into successful weaning group and failed weaning group depending on whether they could be removed from ventilator support within 14 days.

Results of flow cytometric detection of gamma-deltaT cells in peripheral blood of patients with ankylosing spondylitis: a pilot study.

Previous studies have suggested that gamma-delta T cells play an important role in the pathogenesis of ankylosing spondylitis (AS). In this pilot study, the peripheral blood mononuclear cells (PBMCs) of patients with ankylosing spondylitis (AS) and healthy volunteers were stained and analyzed by flow cytometry to distinguish gamma-delta T cells and its subtypes, and then to report the distribution of gamma-delta T cells and iyts subtypes and their correlation with ankylosing spondylitis. A total of 17 patients with active AS and 10 age- and gender- matched healthy volunteers were enrolled in this study, and their peripheral blood were drawn to collect mononuclear cells (PBMCs).

Identification of Biomarker in Ankylosing Spondylitis via Multi-Chip Integration Analysis of Gene Differential Expression.

Layered Pd oxide on PdSn nanowires for boosting direct HO synthesis.

Hydrogen peroxide (HO) has the wide range of applications in industry and living life. However, the development of the efficient heterogeneous catalyst in the direct HO synthesis (DHS) from H and O remains a formidable challenge because of the low HO producibility. Herein, we develop a two-step approach to prepare PdSn nanowire catalysts, which comprises Pd oxide layered on PdSn nanowires (Pd/PdSn-NW).

A simple and efficient protocol for transient transformation of sliced grape berries.

Grape is an economically important crop but recalcitrant to Agrobacterium-mediated genetic transformation and in vitro regeneration. Here, we have developed a protocol for transient transformation of grapes by investigating the effects of explant pre-culture and duration of vacuum infiltration on transformation efficiency. Using sliced grape berries of "Shine-Muscat" (Vitis labrusca × Vitis vinifera) between the end of fruit expansion phase and the mature stage as explants, we firstly compared the effect of pre-culture explants into a susceptible state (incubation on Murashige and Skoog (MS) agar plate in the dark at 25 ± 1 °C for 48 h) with no pre-culture and then tested different vacuum infiltration times on transformation efficiency using β-glucuronidase (GUS) reporter system.

Constructing N, P-dually doped biochar materials from biomass wastes for high-performance bifunctional oxygen electrocatalysts.

The large scale lignocellulosic biomass wastes could also be regarded as abundantly-available renewable resources, and how to convert them into value-added products via sustainable approaches is still a big challenge. In this work, we demonstrated a facile pyrolysis method to construct N, P-dually doped biochar materials from the lignocellulosic biomass wastes. The as-synthesized N, P-dually doped biochar samples could act as electrocatalysts for oxygen reduction and evolution reactions (ORR/OER), showing excellent catalytic performance and long-term durability, as well as robust tolerance to CO and methanol.

Destrin Contributes to Lung Adenocarcinoma Progression by Activating Wnt/β-Catenin Signaling Pathway.

Lung cancer, especially lung adenocarcinoma, is one of the most common neoplasms worldwide. However, the mechanisms underlying its initiation, development, and metastasis are still poorly understood. Destrin (DSTN) is a member of ADF/cofilin family.

Do Rural Residents in China Understand EQ-5D-5L as Intended? Evidence From a Qualitative Study.

Background: The 5-level EQ-5D (EQ-5D-5L) has been increasingly used in China to measure the health status of the general population and patients. However, its content validity among rural residents in China has not been formally evaluated. This qualitative study aims to assess the content validity of EQ-5D-5L among rural Chinese.

Analysis of daily goal sheets on physician-nurse collaboration attitude.

Background: Optimal communication and collaboration between inter-disciplinary health care providers is critical to ensuring high quality patient care. We aimed to quantify the impact on physician-nurse collaboration (PNC) of implementing daily goal sheets (DGSs) in emergency settings.

Methods: The usage of a DGS was administered in morning rounds in an emergency intensive care unit (ICU) for four consecutive months.

Efficient electrochemical production of glucaric acid and H via glucose electrolysis.

Glucose electrolysis offers a prospect of value-added glucaric acid synthesis and energy-saving hydrogen production from the biomass-based platform molecules. Here we report that nanostructured NiFe oxide (NiFeO) and nitride (NiFeN) catalysts, synthesized from NiFe layered double hydroxide nanosheet arrays on three-dimensional Ni foams, demonstrate a high activity and selectivity towards anodic glucose oxidation. The electrolytic cell assembled with these two catalysts can deliver 100 mA cm at 1.

Pseudocapacitive Ni-Co-Fe Hydroxides/N-Doped Carbon Nanoplates-Based Electrocatalyst for Efficient Oxygen Evolution.

The oxygen evolution reaction (OER) catalytic activity of a transition metal oxides/hydroxides based electrocatalyst is related to its pseudocapacitance at potentials lower than the OER standard potential. Thus, a well-defined pseudocapacitance could be a great supplement to boost OER. Herein, a highly pseudocapacitive Ni-Fe-Co hydroxides/N-doped carbon nanoplates (NiCoFe-NC)-based electrocatalyst is synthesized using a facile one-pot solvothermal approach.

Maternal genetic backgrounds contribute to the genetic susceptibility of tongue cancer patients in Hunan, central of China.

Mitochondrial DNA (mtDNA) mutations played crucial roles on affecting the susceptibility to cancer. In this study, to investigate whether mitochondrial DNA mutations contributed to the genetic susceptibility of Chinese tongue cancer patients, mtDNA control regions of 105 Chinese tongue cancer patients were amplified and sequenced, the mutations were recorded by comparing with the revised Cambridge Reference Sequence (rCRS), which were attributed to certain mtDNA haplogroups based on the specific variations motif of each patients. The Miao Chinese group (a Chinese ethnic minority) from surrounding region has no essential difference with tongue cancer group, which was taken as the matched control group with principal component analysis by taking the haplogroups frequency of 105 tongue cancer individuals and 354 healthy individuals of eight groups from the similar geographic regions as input factors.

[The research progress in determining lignocellulosic content by near infrared reflectance spectroscopy technology].

Near infrared reflectance spectroscopy technology, as a new analytic method, can be used to determine the content of lignin, cellulose and hemi-cellulose which is faster, effective, easier to operate, and more accurate than the traditional wet chemical methods. Nowadays it has been widely used in measuring the composition of lignocelluloses in woody plant and herbaceous plant. The domestic and foreign research progress in determining the lignin, cellulose and hemi-cellulose content in woody plant ( wood and bamboo used as papermaking raw materials and wood served as potential biomass energy) and herbaceous plant (forage grass and energy grass) by near infrared reflectance spectroscopy technology is comprehensively summarized and the advances in method studies of measuring the composition of lignocelluloses by near infrared reflectance spectroscopy technology are summed up in three aspects, sample preparation, spectral data pretreatment and wavelength selection methods, and chemometric analysis respectively.

In order to differently diagnose avian influenza virus (AIV) subtypes, the HA gene of AIV H9 subtype was cloned, expressed and utilized in an enzyme-linked immunoad sorbent assay (ELISA). HA gene (1683bp) of H9N2 AIV was amplified by RT-PCR from a strain of field isolated H9N2 AIV, and its identity was confirmed by sequencing. The HA gene was subcloned into prokaryotic expression vector pGEX-KG with its secretion signal sequence removed.
