Formation of single-dominant-species patches of primarily influenced by understory light intensity.

Introduction: The fern community plays vital roles in nutrient sequestration, succession regulation, and ecological threshold control. However, the mechanisms underlying the formation of the -dominant community remain unclear.

Methods: This study established four different community types to investigate the effects of environmental factors on the formation of a -dominant community.

Trimethylamine N-oxide induces non-alcoholic fatty liver disease by activating the PERK.

Nonalcoholic fatty liver disease (NAFLD) is a liver disease causing different progressive pathological changes. Trimethylamine N-oxide (TMAO), a product of gut microbiota metabolism, is a specific agonist of the protein kinase R-like endoplasmic reticulum kinase (PERK) pathway, one of the endoplasmic reticulum stress (ERS) pathways. TMAO has been associated with the occurrence and development of NAFLD based on the results of previous studies, but whether the simple consumption of TMAO can directly induce NAFLD and its underlying mechanism remain unclear.

Prevalence and factors associated with dynapenia among middle-aged and elderly people in rural southern China.

To estimate the prevalence of dynapenia and examine potential risk factors for dynapenia using a sample of rural middle-aged and elderly Chinese. A cross-sectional study of 253 Chinese adults aged 50 years and older was conducted from June to August in 2022 in Nanjing. A questionnaire was used to collect data on all socioeconomic variables.

Comprehensive identification of terpene synthase genes and organ-dependent accumulation of terpenoid volatiles in a traditional medicinal plant L.

L. is a traditional medicinal plant of Nordic origin that produces an unusual amount and variety of terpenoids. The unique terpenoid composition of likely arises from the involvement of terpene synthases (TPSs) with different specificities, none of which has been identified.

Enhanced cadmium phytoremediation capacity of poplar is associated with increased biomass and Cd accumulation under nitrogen deposition conditions.

Nitrogen (N) deposition plays a significant role in soil cadmium (Cd) phytoremediation, and poplar has been considered for the remediation of contaminated soil because of its enormous biomass and strong Cd resistance. To reveal the underlying physiological and root phenotypic mechanisms of N deposition affecting Cd phytoextraction in poplar, we assessed root phenotypic characteristics, Cd absorption and translocation, chlorophyll fluorescence performance, and antioxidant enzyme activities of a clone of Populus deltoides × P. nigra through combined greenhouse Cd and N experiments.

Improving Electrochemical Performance of Thick Silicon Film Anodes with Implanted Solid Lithium Source Electrolyte.

Silicon is a potential next-generation anode material for a lithium-ion battery. However, the large-scale application of silicon is restricted by poor electrical conductivity, large volume change, and high irreversible capacity during the charge/discharge process. Here, we proposed a simple strategy by preimplanting a solid lithium source electrolyte (LiCO and LiO) into Si thick film to improve the electrochemical properties of Si materials.

Analysis of low sexual desire in Chinese women: a national population-based epidemiological survey in mainland China.

Unlabelled: Background Low sexual desire is the most prevalent female sexual health problem; however, national epidemiologic data on female sexual desire in China are absent. Understanding factors related to low sexual desire are essential in preparing educational and consultative programs and policies to improve women's sexual health.

Methods: A national epidemiological survey on female sexual function was conducted from February 2014 to January 2016 in mainland China.

A Population-Based Epidemiologic Study of Female Sexual Dysfunction Risk in Mainland China: Prevalence and Predictors.

Background: Epidemiologic data on female sexual dysfunction in China are sparse.

Aim: To assess the prevalence of risk of female sexual dysfunction in mainland China and its regional and sociodemographic variations and physiologic, pathologic, and behavioral risk factors.

Methods: A survey of the general female population was conducted in mainland China from February 2014 through January 2016.

FasL -844T/C and Fas -1377G/A: mutations of pulmonary adenocarcinoma in South China and their clinical significances.

Apoptosis is an important mechanism of malignant tumor formation and progression. Single nucleotide polymorphisms (SNPs) located within cell death genes may influence cancer risk. We explored the relationship between FasL -844T/C and/or Fas -1377G/A SNPs and pulmonary adenocarcinoma (AD).

New classification of Herlyn-Werner-Wunderlich syndrome.

Background: Uterus didelphys and blind hemivagina associated with ipsilateral renal agenesis are collectively known as Herlyn-Werner-Wunderlich syndrome (HWWS). In the literature, the syndrome often appears as a single case report or as a small series. In our study, we reviewed the characteristics of all HWWS patients at Peking Union Medical College Hospital (PUMCH) and suggested a new classification for this syndrome because the clinical characteristics differed significantly between the completely and incompletely obstructed vaginal septum.

Endometriosis in association with Herlyn-Werner-Wunderlich syndrome.

Objective: To describe the clinical characteristics of patients with Herlyn-Werner-Wunderlich syndrome (HWWS) and explore the relationship between an obstructive genital abnormality and pelvic endometriosis.

Design: Case series.

Setting: University hospital.

Clinical characteristics of 70 patients with Herlyn-Werner-Wunderlich syndrome.

Objective: To analyze the clinical characteristics of patients with Herlyn-Werner-Wunderlich (HWW) syndrome.

Methods: Seventy patients with a confirmed diagnosis of HWW syndrome admitted to the Peking Union Medical College Hospital between January 1995 and December 2010 were retrospectively reviewed, and long-term follow-up data were analyzed.

Results: The lateral distribution of hemivaginal obstruction and renal agenesis favored the right side in 42 patients (60.

[Study on pathological characteristics of eutopic endometrium in endometriosis].

Objective: To study the pathologic characteristics of eutopic endometrium in patients with endometriosis.

Methods: Pathologic characteristics of eutopic endometrium were studied in 176 patients with endometriosis in Peking Union Medical College Hospital from January 2007 to December 2008 retrospectively.

Results: About 72.

Microarray analysis of differentially expressed genes in vaginal tissues in postmenopausal women. The role of stress urinary incontinence.

Introduction And Hypothesis: This study aimed to explore gene expression and their regulatory mechanisms in etiology of stress urinary incontinence (SUI).

Methods: Tissue samples were taken from the paraurethral vaginal wall from three pairs of postmenopausal, age/body mass index/parity-matched SUI, and continent women and subjected to microarray analysis using the Affymetrix GeneChip® Human Genome U133 Plus 2.0 oligonucleotide chip set.

[Effects of laparoscopic Burch colposuspension and tension-free vaginal tape in treatment of female stress urinary incontinence: a comparative study].

Objective: To evaluate the efficacy and complications of laparoscopic Burch colposuspension and tension-free vaginal tape (TVT) in treatment of female stress urinary incontinence (SUI).

Methods: Thirty patients underwent laparoscopic Burch colposuspension and 67 age, BMI, parity, and grading-matched patients underwent TVT because of moderate to severe hypermotility urodynamic SUI from 2002 to 2006. Follow-up was conducted for (9 +/- 10) months.
