Insights into the long-term immobilization performances and mechanisms of CMC-Fe/FeS with different sulfur sources for uranium under anoxic and oxic aging.

Nanoscale zerovalent iron (Fe)-based materials have been demonstrated to be a effective method for the U(VI) removal. However, limited research has been conducted on the long-term immobilization efficiency and mechanism of Fe-based materials for U(VI), which are essential for achieving safe handling and disposal of U(VI) on a large scale. In this study, the prepared carboxymethyl cellulose (CMC) and sulfurization dual stabilized Fe (CMC-Fe/FeS) exhibited excellent long-term immobilization performances for U(VI) under both anoxic and oxic conditions, with the immobilization efficiencies were respectively reached over 98.

Research trends in biodiversity loss: a bibliometric analysis.

Although increased attempts to preserve biodiversity ecosystems have been widely publicized, bibliometric research of biodiversity loss remains limited. Using VOSviewer, we hope to provide a bibliometric assessment of global research trends on biodiversity loss from 1990 to 2021. Document type, language, publication trend, countries, institutions, Author Keywords, and Keywords Plus were all examined.

Environmental Kuznets curve for biodiversity loss: evidence from South and Southeast Asian countries.

This study aims to explore the income-biodiversity loss nexus in South and Southeast Asian countries covering the period between 2013 and 2019. Negative Binomial regression models are used to deal with the count regressand variable with specific emphasis on different taxonomic groups of threatened species, namely, mammal, bird, reptile, amphibian, fish, mollusk, other invertebrate, plant, and total threatened species. We find strong support of an inverted U-shaped relationship between income and biodiversity loss in all taxonomic groups of threatened species examined.

Habitat change and biodiversity loss in South and Southeast Asian countries.

South and Southeast Asia is by far the most populous region in Asia, with the greatest number of threatened species. Changes in habitat are a major contributor to biodiversity loss and are more common as a result of land-use changes. As a result, the goal of this study is to use negative binomial regression models to investigate habitat change as one of the important drivers of biodiversity loss in South and Southeast Asian countries from 2013 to 2018.

Effectiveness of Ultrasound-Guided Versus Anatomic Landmark-Guided Corticosteroid Injection on Pain, Physical Function, and Safety in Patients With Subacromial Impingement Syndrome: A Systematic Review and Meta-analysis.

Objective: The aim of the study was to compare the efficacy and safety of ultrasound-guided versus anatomic landmark-guided corticosteroid injection for the treatment of subacromial impingement syndrome.

Design: PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, Scopus, ClinicalTrials.gov , CBM, CNKI, and Wanfang databases were searched from inception to August 15, 2021, for randomized controlled trials comparing ultrasound-guided versus anatomic landmark-guided injections of corticosteroids for the treatment of subacromial impingement syndrome.

Primitive neuroectodermal tumor of the cervix diagnosed during pregnancy: a rare case report with discussion.

Background: Primitive neuroectodermal tumor (PNET) is a relatively rare malignant small round cell tumor, and the occurrence of cervical PNET during pregnancy is extremely rare.

Case Presentation: A case of pregnancy complicated by PNET at our hospital was reported. A 19-year-old pregnant woman presented to the hospital due to multiple instances of vaginal bleeding during the first and second trimesters.

[Influence of electroacupuncture on locomotor function and expression of spinal HMGB1 and TLR4 in mice with spinal cord injury].

Objective: To observe the effect of electroacupuncture(EA)on locomotor activity and the expression of high-mobility group box-1(HMGB1) and Toll-like receptor 4(TLR4) in mice with spinal cord injury(SCI), so as to explore its mechanisms underlying improvement of SCI at the acute stage.

Methods: Forty-eight female C57BL/6 mice were equally randomized into 3 groups: sham operation, model and EA. The SCI model was established by clamping the spinal cord with a serrefine after laminectomy at the 1st lumbar vertebra(L1).

[Effects of electroacupuncture at "Jiaji"(EX-B2) on autophagy and endoplasmic reticulum stress in spinal cord injury mice].

Objective: To observe the effect of electroacupuncture (EA) at "Jiaji" (EX-B2) on the levels of autophagy and endoplasmic reticulum stress in mice with spinal cord injury (SCI), so as to explore its mechanism underlying improvement of SCI.

Methods: A total of 60 female C57BL/6 mice were randomly divided into sham operation, model and EA groups， which were further divided into 7 d and 14 d subgroups (10 mice in each subgroup). The SCI model was established by pressing the exposed spinal cord (L1) with a vascular clamp for 15 s.

The prognostic implications of perioperative endogenous hydrogen sulfide and nitric oxide levels in children with congenital heart disease complicated by pulmonary arterial hypertension.

The goal of this study was to measure perioperative changes in endogenous hydrogen sulfide (HS) and nitric oxide (NO) levels in children with congenital heart disease (CHD) complicated by pulmonary arterial hypertension (PAH), with the goal of better monitoring these children and evaluating their prognosis. For this study, we enrolled 48 normal control cases, 48 preoperative CHD cases including 16 without PAH, 16 with mild PAH, and 16 with moderate-to-severe PAH. We additionally enrolled a cohort of 32 other children with PAH-CHD that had undergone CHD correction prior to transfer to an intensive care unit (ICU).

A moderately extended time interval between hCG administration and oocyte retrieval is good for most patients with oocyte retrieval scheduled on the same day: a retrospective cohort study.

Evidence is limited regarding the time intervals between human chorionic gonadotropin (hCG) administration and oocyte retrieval in controlled ovarian hyperstimulation cycles, and it is difficult to determine proper schedules to optimise outcomes for patients undergoing oocyte retrieval on the same day. We aimed to identify correlations between factors pertaining to treatment outcomes and time intervals to facilitate working schedules of ART centres. Our study included 2509 patients who underwent ICSI cycles.

Distinct Prevalence of Drug-Resistant Tuberculosis in Gansu, China: A Retrospective Study on Drug Susceptibility Profiles Between 2010 and 2014.

Limited knowledge is available on regional distribution of antituberculosis (TB) drug resistance and on province-specific time-trends in TB drug susceptibility in China. To obtain the latest information about the dynamics of drug-resistant TB in Gansu province, we conducted a retrospective study and analyzed data on drug resistance among new TB cases diagnosed between June 2010 and May 2014 in Gansu, China. The data were collected from the only TB surveillance and treatment hospital in Gansu and, therefore, represented the epidemiology of TB in the province.

Effects of Taishan Pinus massoniana pollen polysaccharide on immune response of rabbit haemorrhagic disease tissue inactivated vaccine and on production performance of Rex rabbits.

Varied doses of Taishan Pinus massoniana pollen polysaccharide (TPPPS) and Astragalus polysaccharide (APS) extracted by hot water extraction and ethanol precipitation method were added to the vaccine in order to prepare polysaccharide-rabbit haemorrhagic disease (RHD) tissue inactivated vaccine. The purpose was to study effects of TPPPS on immune response of RHD tissue inactivated vaccine and on production performance of Rex rabbits. Results showed that each index in groups I, II, III and IV was higher than that in group V, especially groups I, II and IV, the difference between which and group V was much more significant (P<0.
