Transcriptome analysis of the effects of different carbon dioxide concentrations on paramylon accumulation in Euglena gracilis Z.

Appropriate concentration of carbon dioxide (CO) will promote algae growth and metabolism. Building upon this finding, the present study investigated the impact of different CO concentrations (5% and 20%) on the carbon sequestration capacity of E. gracilis through aeration culturing, employing a combination of physiological analyses and transcriptome analysis.

[Characteristics of Benthic Diatom Community Structure and Water Ecological Health Evaluation in the Lalin River Basin].

With the improvement of public requirements for the health status of aquatic ecosystems, there have been innovative assessment methods developed for aquatic ecosystems. In this study, benthic algae assemblages and water quality variables were analyzed to develop a benthic diatom-based index of biotic integrity (D-IBI) for the assessment of the aquatic environment in the Lalin River. In addition, using redundancy analysis (RDA) based on dominant species and physicochemical indexes, the ecological distribution characteristics of the benthic diatom community were revealed, and the key influencing factors were identified.

Early renal impairment is associated with in-hospital death of patients with COVID-19.

Introduction: Renal impairment is a common complication in coronavirus disease 2019 (COVID-19), although its prognostic significance remains unknown.

Objectives: This study determines the impact of early renal impairment on the clinical outcome of COVID-19.

Methods: Patients diagnosed with COVID-19 and hospitalized in Xiaogan Central Hospital from 20 January to 29 February 2020 were retrospectively included and grouped into two cohorts (cohort with normal renal function and cohort with renal insufficiency) based on the renal function detected on admission.

[Incidence and risk factors for anastomotic leakage after anterior resection for rectal cancer].

Objective: To assess the incidence and independent risk factors for clinical anastomotic leakage (AL) in patients undergoing anterior resection(AR) or low anterior resection, (LAR) for rectal cancer.

Methods: This was a retrospective case-control study of 550 patients with rectal cancer who underwent AR or LAR from April 2007 to March 2017 in Beijing Friendship Hospital, Capital Medical University. The relationship between the incidence of AL and clinicopathological manifestations was analyzed by Chi-squared test and Fisher exact test, and the independent risk factors of AL were analyzed using logistic regression analysis.

Serological Screening for Celiac Disease in Adult Chinese Patients With Diarrhea Predominant Irritable Bowel Syndrome.

Celiac disease (CD) is common in Caucasians, but thought to be rare in Asians. Our aim was to determine the prevalence of CD in Chinese patients with chronic diarrhea predominant irritable bowel syndrome (IBS-D).From July 2010 to August 2012, 395 adult patients with IBS-D and 363 age and sex-matched healthy controls were recruited in Zhongnan Hospital of Wuhan University and Xiaogan Central Hospital in Hubei province, central China.

[Serum screening of celiac disease in Chinese adults with diarrhea-predominant irritable bowel syndrome in Hubei, China].

Objective: To screen the prevalence of celiac disease with serologic markers in the central Chinese population, specifically in patients with chronic diarrhea-predominant irritable bowel syndrome (D-IBS).

Methods: A total of 282 adult patients with D-IBS were selected based on ROME III criteria with 296 age and sex matched consecutive healthy individuals as controls. A gluten-free diet (GFD) was advised in subjects positive for IgA/IgG anti-htTG/DGP antibodies and the serologic antibodies were retested after the GFD.

CTLA-4 gene polymorphisms in Chinese patients with ulcerative colitis.

Background: Ulcerative colitis (UC) is characterized by chronic inflammation of the colon and rectum as a result of an exaggerated T-cell response. Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is a T cell-restricted surface molecule induced with TCR or CD28 activation. There is evidence for genetic involvement of CTLA-4 in several autoimmune diseases, with the focus on the possible role of genetic variation of the CTLA-4 locus.
