The Influence of Posture on Attention.

Smith et al. (2019) found standing resulted in better performance than sitting in three different cognitive control paradigms: a Stroop task, a task-switching, and a visual search paradigm. Here, we conducted close replications of the authors' three experiments using larger sample sizes than the original work.

Effect of Repetitive Transcranial Magnetic Stimulation in Inducing Weight Loss in Patients with Chronic Schizophrenia: A Randomized, Double-Blind Controlled 4-Week Study.

Objectives: There is emerging evidence that high-frequency (HF) repetitive transcranial magnetic stimulation (rTMS) may promote weight loss in individuals with obesity in the general population. However, no study has been conducted on patients with schizophrenia (SZ). This study evaluated the efficacy of 10Hz rTMS in reducing body weight in patients with chronic SZ.

A pre-registered, multi-lab non-replication of the action-sentence compatibility effect (ACE).

The Action-sentence Compatibility Effect (ACE) is a well-known demonstration of the role of motor activity in the comprehension of language. Participants are asked to make sensibility judgments on sentences by producing movements toward the body or away from the body. The ACE is the finding that movements are faster when the direction of the movement (e.

Effects of brain-derived neurotrophic factor on oocyte maturation and embryonic development in a rat model of polycystic ovary syndrome.

Brain-derived neurotrophic factor (BDNF) is expressed extensively in the mammalian female reproductive system and has been implicated in the development of follicles and oocytes. However, BDNF expression patterns in the ovary and its effects on oocyte maturation and embryonic development in polycystic ovary syndrome (PCOS) have not been established. In the present study, we established a PCOS model by treating the rats with insulin and human chorionic gonadotropin (hCG).

Prevalence and predictors of metabolic abnormalities in Chinese women with PCOS: a cross- sectional study.

Background: Polycystic ovary syndrome (PCOS) is a common condition estimated to affect 5.61% of Chinese women of reproductive age, but little is known about the prevalence and predictors in Chinese PCOS patients. This study aimed to determine the prevalence and predictors of the metabolic abnormalities in Chinese women with and without PCOS.

Prevalence of polycystic ovary syndrome in women in China: a large community-based study.

Study Question: What is the prevalence of polycystic ovary syndrome (PCOS) in Han Chinese women from different communities?

Summary Answer: The prevalence of PCOS in Chinese women aged 19-45 years is 5.6%.

What Is Known Already: The prevalence of PCOS is reported to range from 5 to 10% but to the best of our knowledge the Han Chinese population has not been studied.

Epidemiology of hirsutism among women of reproductive age in the community: a simplified scoring system.

Objective: The purpose of our research was to generate large sample evidence for the clinical diagnostic criteria of hirsutism and to simplify the modified Ferriman-Galwey (mF-G) scoring system for Asian women.

Study Design: This study was a large-scale, cross-sectional epidemiologic investigation conducted in 10 provinces of China. A total of 10,120 reproductive-age women in the community were involved in using the mF-G scoring system to evaluate hirsutism.

Nested real-time quantitative polymerase chain reaction assay for detection of hepatitis B virus covalently closed circular DNA.

Background: Successful treatment of hepatitis B can be achieved only if the template for hepatitis B virus (HBV) DNA replication, the covalently closed circular HBV DNA (cccDNA) can be completely cleared. To date, detecting cccDNA remains clinically challenging. The purpose of this study was to develop a nested real-time quantitative polymerase chain reaction (PCR) assay for detecting HBV cccDNA in peripheral blood mononuclear cells (PBMCs) and bone marrow mononuclear cells (MMNCs).

miR-122 affects the viability and apoptosis of hepatocellular carcinoma cells.

OBJECTIVE. miR-122 is highly abundant in liver and a hepato-specific microRNA. There is evidence to show that miR-122 expression is down-regulated in human hepatocellular carcinoma (HCC).

An empirical and computational investigation of perceiving and remembering event temporal relations.

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations.

[A multicenter prospective randomized open comparative study on the treatment of ovulatory menorrhagia with tranexamic acid and norethisterone in China].

Objective: To compare the efficacy and safety of tranexamic acid (TA) and norethisterone (NET) for the treatment of patients with ovulatory menorrhagia in China.

Methods: One hundred and thirty one patients with proven ovulatory menorrhagia from gynecologic clinics of 5 teaching hospitals located in 4 different cities in China were enrolled during Jul 2004 to Dec 2006. Among them 128 completed the study.

Perceiving and describing motion events.

According to Hurford, PREDICATE (x) is correlated with deictic object variables during event perception. This claim is inconsistent with some core literature on the perception of motion events. We point out that the perception of events involves the activation of the modal properties and amodal properties of underlying event structure, for which Hurford's target article fails to account.

[The pathogenetic role of peripheral T-lymphocytes activation-induced cell death in hemorrhagic fever with renal syndrome].

Objective: To study the activation-induced cell death (AICD) in peripheral blood T-lymphocytes (PBL-T) from patients of hemorrhagic fever with renal syndrome (HFRS) and the effect of AICD on the pathogenesis of HFRS.

Methods: The PBL-T of patients with HFRS were isolated by negative selection with magnetic beads and cultured with or without phytohemagglutinin (PHA) and ionomycin. The apoptotic ratio of PBL-T was detected with TUNEL staining and assessed with flow cytometry.

Question asking and eye tracking during cognitive disequilibrium: comprehending illustrated texts on devices when the devices break down.

The PREG model of question asking assumes that questions emerge when there is cognitive disequilibrium, as in the case of contradictions, obstacles, and anomalies. Participants read illustrated texts about everyday devices (e.g.

AutoTutor: a tutor with dialogue in natural language.

AutoTutor is a learning environment that tutors students by holding a conversation in natural language. AutoTutor has been developed for Newtonian qualitative physics and computer literacy. Its design was inspired by explanation-based constructivist theories of learning, intelligent tutoring systems that adaptively respond to student knowledge, and empirical research on dialogue patterns in tutorial discourse.

Serum and ascites levels of macrophage migration inhibitory factor, TNF-alpha and IL-6 in patients with chronic virus hepatitis B and hepatitis cirrhosis.

Objective: To study the potential role of macrophage migration inhibitory factor (MIF), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in the development of chronic virus hepatitis B (CH) and hepatitis cirrhosis (HC).

Methods: The serum concentrations of MIF, TNF-alpha and IL-6 in 18 patients with chronic virus hepatitis B and in 14 patients with hepatitis cirrhosis without ascitic fluid, and the serum and ascites cytokine concentrations in 22 HC patients with ascitic fluid were detected by enzyme linked immunity sorbed assay.

Results: The cytokine concentrations of the patients were significantly higher than those of the controls.

Role of activation-induced cell death in pathogenesis of patients with chronic hepatitis B.

Aim: To study and compare the difference of activation-induced cell death (AICD) in peripheral blood T-lymphocytes(PBL-Ts) from patients with chronic hepatitis B (CHB) and the normal people in vitro, and to explore the role of AICD in chronic hepatitis B virus (HBV) infection and the pathogenesis of CHB.

Methods: Twenty-five patients and fourteen healthy people were selected for isolation of PBL-Ts. During cultivation, anti-CD3 mAb, PMA and ionomycin were used for AICD of PBL-Ts.

[Hepatitis C virus nonstructural 5A protein inhibits tumor necrosis factor alpha mediated apoptosis of HepG2 cells].

Objective: To study the suppressive effect of HCV nonstructural 5A (NS5A) protein on tumor necrosis factor alpha (TNF alpha) mediated apoptosis of HepG2 cells.
