Novel Sulfate Reduction Coupled to Simultaneous Nitrification and Autotrophic Denitrification Process for Removing Nitrogen and Organics from Saline Wastewater.

Highly efficient sulfate reduction coupled to autotrophic denitrification plus nitrification is demonstrated by integrating an anaerobic membrane bioreactor (AnMBR) with a membrane aerated biofilm reactor (MABR). Concurrent chemical oxygen demand (COD) removal and sulfate reduction were accomplished in the AnMBR, while simultaneous nitrification and autotrophic denitrification were carried out in the MABR. Separate operation of the MABR achieved >90% total nitrogen (TN) removal when the N/S ratio was controlled at 0.

Coexistence of GLIM-defined malnutrition and sarcopenia have negative effect on the clinical outcomes in the elderly gastric cancer patients after radical gastrectomy.

Background: Malnutrition and sarcopenia are common in elderly gastric cancer patients, which are also interrelated and affect each other. We aimed to determine the characteristics of coexistence of malnutrition and sarcopenia in the elderly gastric cancer patients and investigate the predictive roles of malnutrition and sarcopenia on clinical outcomes.

Methods: Between 2014 and 2019, a total of 742 elderly gastric cancer patients were enrolled.

Prognostic value of myosteatosis and sarcopenia for elderly patients with colorectal cancer: A large-scale double-center study.

Background: Myosteatosis and sarcopenia are forms of muscle depletion that impair the normal physiological function of elderly patients, resulting in a worse prognosis. This study aimed to evaluate the prognostic value of sarcopenia and myosteatosis on postoperative outcomes in elderly patients with colorectal cancer.

Methods: From February 2015 to March 2021, a total of 921 elderly patients who underwent curative surgeries for colorectal cancer at 2 centers were enrolled and grouped by the presence of either myosteatosis or sarcopenia.

Comparisons and Impacts of the Basic Components of Sarcopenia Definition and Their Pairwise Combinations in Gastric Cancer: A Large-Scale Study in a Chinese Population.

Sarcopenia is negatively associated with clinical outcomes. However, the definitions of sarcopenia are inconsistent across international consensuses. Thus, the purpose of this study is to compare the impact of the basic definition components of sarcopenia and their combinations in post-operative complications and overall survival, aiming to find the best sarcopenia definition to stratify the prognosis in an Asian population.

Impact of sarcopenia on clinical outcomes of patients with stage I gastric cancer after radical gastrectomy: A prospective cohort study.

Background: The relationships between sarcopenia and postoperative outcomes in patients with early-stage gastric cancer who undergo radical gastrectomy is unclear. We aimed to investigate the predictive value of sarcopenia on adverse outcomes for stage I gastric cancer.

Methods: The clinical data of patients who underwent radical gastrectomy for stage I gastric cancer between July 2013 and May 2019 were prospectively collected.

Feasibility of substituting handgrip strength for muscle mass as a constituent standard in the Global Leadership Initiative on Malnutrition for diagnosing malnutrition in patients with gastrointestinal cancers.

Objectives: The aim of this study was to determine the feasibility of substituting handgrip strength (HGS) for muscle mass as a constituent in the Global Leadership Initiative on Malnutrition (GLIM) to diagnose malnourished patients with gastrointestinal (GI) cancer.

Methods: The study included 2209 patients diagnosed with GI cancer from two centers. All patients were evaluated for nutritional risk using Nutritional Risk Screening 2002 within 24 h of admission.

A comparison of four common malnutrition risk screening tools for detecting cachexia in patients with curable gastric cancer.

Objective: Although there is international consensus regarding the importance of cachexia, no tools exist, to our knowledge, for cachexia screening among patients with cancer. The aim of this study was to evaluate whether patients with cancer and cachexia could be identified using the four most commonly used nutritional screening tools: the Malnutrition Universal Screening Tool (MUST), the Nutritional Risk Screening (NRS)-2002, the Malnutrition Screening Tool (MST), and the Short Nutritional Assessment Questionnaire (SNAQ).

Methods: Clinical data were prospectively collected for patients who underwent elective radical gastrectomy for gastric cancer in two large centers between August 2014 and February 2018.

Sarcopenia is an effective prognostic indicator of postoperative outcomes in laparoscopic-assisted gastrectomy.

Background: The association between sarcopenia and postoperative outcomes in patients who undergo laparoscopic-assisted gastrectomy is unclear. We aimed to determine the predictive value of sarcopenia for adverse postoperative outcomes after laparoscopic-assisted gastrectomy for gastric cancer.

Materials And Methods: We prospectively collected the clinical data of patients who underwent elective radical laparoscopic-assisted gastrectomy for gastric cancer in two large centers from August 2014 to October 2017.

Nrf2 deficiency exacerbates frailty and sarcopenia by impairing skeletal muscle mitochondrial biogenesis and dynamics in an age-dependent manner.

Aim: Mitochondrial dysfunction during aging is a key factor that contributes to sarcopenia. Nuclear factor erythroid 2-related factor 2 (Nrf2) has been increasingly recognized to regulate mitochondrial function. The present study aimed to investigate the role of Nrf2 in the development of frailty and sarcopenia during aging, and to demonstrate whether Nrf2 contributes to the maintenance of muscle mass and function by regulation of mitochondrial biogenesis and dynamics during the aging process.

Objective: From gene lever identified the asexual stage of Taishan cordyceps.

Methods: Using rDNA ITS regions as molecular targets, PCR amplification, sequencing, and comparing with the other ITS region sequences of known.

Results: Through the Blast search of GenBank, the ITS sequence is same as the sequence of Paecilomyces tenuipes (100% ).

[Research on seasonal variation of self-purification ability for small shallow lakes in South Lake Taihu].

Seasonal variations of self-purification ability for small natural shallow lakes in South Lake Taihu were investigated. The results showed that seasonal difference of self-purification of permanganate index, total nitrogen (TN), ammonium (NH4(+)-N), nitrate (NO3(-)-N), total phosphorus (TP), chlorophyll (Chl-a) in small shallow lakes were remarkable. Effects of self-purification were better in spring and winter, and were worse in summer by NH4(+)-N and NO3(-)-N and in autumn by TP and Chl-a.

Perfluorinated compounds in whole blood samples from infants, children, and adults in China.

Two hundred and forty five human blood (whole blood) samples from Chinese donors aged from 0 to 90 yrs were analyzed for 10 perfluorinated compounds (PFCs). Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) were the most abundant PFCs found in blood. The median concentration of PFOS was lower in nonadults (i.
