Effects of saponins R and R in intervention on intestinal microbiota of aging model.

Aging brings about physiological dysfunction, disease, and eventual mortality. An increasing number of studies indicate that aging can easily lead to dysbiosis of the gut microbiota, which can further affect digestion, nerves, cognition, emotions, and more. Therefore, gut bacteria play an important role in regulating the physical functions of aging populations.

Improving the identification and diagnostic efficiency of Metagenomic Next-Generation Sequencing for mycobacterial granuloma on postoperative formalin-fixed paraffin-embedded specimens.

Objective: Metagenomic Next-Generation Sequencing (mNGS) has been validated to have an important role in the diagnosis of mycobacterium infection. The study aimed to further explore the mycobacteria identification ability of mNGS on formalin-fixed paraffin-embedded（FFPE）tissues from postoperative specimens.

Methods: Patients who underwent surgical biopsy or resection for clarifying the diagnosis and whose initial postoperative pathology indicated granulomatous lesions were included.

Impact of Internet Integrated Financial Education on Students' Financial Awareness and Financial Behavior.

In daily life, most people engage in money-related behavior. Adequate financial knowledge is required to successfully manage tasks, such as daily expenditure and the transformation of assets or debts, small, or large. However, the extent of financial knowledge may vary between individuals.

A case-control study on the association of intestinal flora with ulcerative colitis.

The association between intestinal flora and ulcerative colitis (UC) was studied in order to provide a basis and method for clinical treatment. Fresh fecal samples were collected from 30 active UC patients and 10 healthy controls. The intestinal flora DNA from each sample was extracted and 16S rRNA gene sequencing was carried out using HiSeq platform to identify the intestinal flora in fecal samples.

Photo-Induced Charge Transfer on Pt/Bi₂WO Composite Photocatalysts.

Pt/Bi₂WO composite photocatalysts were prepared by a facile photoreduction method. Pt nanoparticles with an average size of 5-8 nm were successfully deposited on the surface of Bi₂WO microspheres and the photocatalytic activity of Bi₂WO was greatly improved by Pt nanoparticles. The photo-induced charge transfer properties of samples were studied by means of surface photovoltage (SPV) and transient photovoltage (TPV) techniques, giving an insight into the intrinsic reasons of the improvement in photocatalytic activity.

Anti-inflammatory monoterpene esters from the stems of .

Two new monoterpene esters illigerates F and G ( and ) together with 5 know compounds illigerate A (), illigerate C (), actinodaphnine (), N-methylactinodaphnine() and N-methyllaurotetanine() were isolated from S. Z. Huang et S.

A clinical risk model for the evaluation of bronchopleural fistula in non-small cell lung cancer after pneumonectomy.

Background: There are no reliable risk factors to predict bronchopleural fistula (BPF) formation in patients undergoing pneumonectomy for non-small cell lung cancer (NSCLC). This study aims to create a validated clinical model based on the risk factors for BPF after pneumonectomy. The model to estimate the risk of BPF may help select patients for intervention therapy to reduce the rate of BPF after pneumonectomy.

Risk factors for early postoperative complications after pneumonectomy for benign lung disease.

Background: Pneumonectomy is associated with a significant incidence of postoperative complications. The purpose of this study is to identify the risk factors associated with adverse outcomes.

Methods: One hundred thirty-six patients with benign lung disease who underwent pneumonectomy were included in this retrospective analysis.

[Video-assisted thoracic surgery lobectomy versus open lobectomy for mini pathologic N2 non-small cell lung cancer].

Objective: To assess early and late outcomes of patients with minimal mediastinal lymph nodes metastasis N2 non-small cell lung cancer disease unexpectedly detected during the operation, who underwent video-assisted thoracic surgery lobectomy for clinical stage I.

Methods: This study retrospectively reviewed and analyzed the medical records of 263 patients underwent surgery between January 2004 and December 2007, who were diagnosed as having early-stage non-small cell lung cancer (clinical stage was cT1-2N0M0, stage I) before the surgery, but were found to have mini mediastinal lymph nodes metastasis disease (clinical stage was pT1-2N2M0, stage IIIa) unexpectedly detected during the operation and after the operation. All patients underwent lobectomy and systematic lymph nodes dissection as radical treatments.

Photosynthesis, non-photochemical pathways and activities of antioxidant enzymes in a resilient evergreen oak under different climatic conditions from a valley-savanna in Southwest China.

Plants in the savanna-valleys in Southwest China are annually exposed to different combinations of multiple stresses from the hot-rainy, to chill-dry, and to warm-dry seasons. This study monitored seasonal changes in photosynthesis and photoprotection in an evergreen oak (Cyclobalanopsis helferiana) from one of these valleys for four years during which usual and abnormal drought occurred. In general, during the study period with decreasing xylem water potential (Psix), photosynthetic gas exchange, quantum yield of photosystem II (PSII) photochemistry and activities of most of the measured antioxidant enzymes decreased, while activities of the xanthophyll cycle and associated non-photochemical energy dissipation and glutathione peroxidase (GP) (EC 1.

Method to differentiate asn deamidation that occurred prior to and during sample preparation of a monoclonal antibody.

Asparagine (Asn) deamidation is a major source of antibody instability and micro heterogeneity. For this reason, it is critical to accurately characterize both the levels and the sites of Asn deamidation in therapeutic antibodies. Asn deamidation is normally quantified by analyzing antibodies at the peptide level by liquid chromatography-mass spectrometry.

Capillary gas chromatographic determination of dimethachlon residues in fresh tobacco leaves and cut-tobacco.

Simple procedures for extraction and chromatographic determination of dimethachlon residues in fresh tobacco leaves and cut-tobacco are described. The determination was carried out by capillary gas chromatography (GC) with electron capture detection (ECD) and confirmed by GC-MS. The mean recoveries and relative standard deviation (RSD) were 93.

[Centralized management strategy of the infant incubators in NICUs].

There are many problems existing at present in the incubator applications and management. Among them, the prominent problems are their cleaning and disinfection. We hope to find, through the centralized management and clinical engineering, an efficient strategy in order to get more reasonable and better maintenance, cleaning and training for infant incubators in NICUs.
