Knockdown of microRNA390 Enhances Maize Brace Root Growth.

Brace root architecture is a critical determinant of maize's stalk anchorage and nutrition uptake, influencing root lodging resistance, stress tolerance, and plant growth. To identify the key microRNAs (miRNAs) in control of maize brace root growth, we performed small RNA sequencing using brace root samples at emergence and growth stages. We focused on the genetic modulation of brace root development in maize through manipulation of miR390 and its downstream regulated ().

Impact of hypoxia on glucose metabolism and hypoxia signaling pathways in juvenile horseshoe crabs Tachypleus tridentatus.

Marine hypoxia poses a significant challenge in the contemporary marine environment. The horseshoe crab, an ancient benthic marine organism, is confronted with the potential threat of species extinction due to hypoxia, making it an ideal candidate for studying hypoxia tolerance mechanisms. In this experiment, juvenile Tachypleus tridentatus were subjected to a 21-day trial at DO:2 mg/L (hypoxia) and DO:6 mg/L conditions.

A phase 3 randomized, open-label study evaluating the immunogenicity and safety of concomitant and staggered administration of a live, pentavalent rotavirus vaccine and an inactivated poliomyelitis vaccine in healthy infants in China.

This open-label, randomized, phase 3 study in China (V260-074; NCT04481191) evaluated the immunogenicity and safety of concomitant and staggered administration of three doses of an oral, live, pentavalent rotavirus vaccine (RV5) and three doses of an intramuscular, inactivated poliomyelitis vaccine (IPV) in 400 healthy infants. The primary objective was the non-inferiority of neutralizing antibody (nAb) responses in the concomitant- versus the staggered-use groups. Antibody responses were measured at baseline and 1-month post-dose 3 (PD3).

Combined effects of norfloxacin and polystyrene nanoparticles on the oxidative stress and gut health of the juvenile horseshoe crab Tachypleus tridentatus.

Pollution with anthropogenic contaminants including antibiotics and nanoplastics leads to gradual deterioration of the marine environment, which threatens endangered species such as the horseshoe crab Tachypleus tridentatus. We assessed the potential toxic mechanisms of an antibiotic (norfloxacin, 0, 0.5, 5 μg/L) and polystyrene nanoparticles (10 particles/L) in T.

Physical condition and activity of daily living among aging inpatients with mental disorders in Guangzhou, China: a cross-sectional study.

Background: The number of elderly with mental disorders is increasing, but few studies have been concerned with the physical condition and activities of daily living (ADL) of these patients. This study aims to describe the physical condition and ADL of patients with mental illnesses (PMI) from different age groups, which provides evidence to improve mental health services for PMI.

Methods: In this prospective cross-sectional study, the samples were divided into three groups of less than 60 years old (group 1), 60-74 years old (group 2), and over 75 years old (group 3) for comparison.

Predictors of everyday functional impairment in older patients with schizophrenia: A cross-sectional study.

Objective: This study investigates the prevalence of everyday functional impairment among older adults with schizophrenia and builds a predictive model of functional decline.

Methods: A total of 113 hospitalized older patients enrolled in this study. Functional impairment is defined according to the Functional Activities Questionnaire (FAQ).

Psychological stress and psychological support of Chinese nurses during severe public health events.

The domestic health care system has been facing a difficult task, especially in medical care, and Chinese nurses are under tremendous psychological pressure. Psychological support is a protective factor to relieve stress. This study examined the stress level and characteristics of Chinese nurses with different psychological support-seeking behaviours.

Immunogenicity and safety of two novel human papillomavirus 4- and 9-valent vaccines in Chinese women aged 20-45 years: A randomized, blinded, controlled with Gardasil (type 6/11/16/18), phase III non-inferiority clinical trial.

Background: Human papillomavirus (HPV) infections were the main cause of anogenital cancers and warts. HPV 6/11/16/18 vaccines provide protection against the high-risk types of HPV responsible for 70% of cervical cancers and 90% of genital warts. This randomized, blinded, non-inferiority phase III trial was to determine whether immunogenicity and tolerability would be non-inferior among women after receiving two novel 4- and 9-valent HPV vaccines (4vHPV, HPV 6/11/16/18; 9vHPV, HPV 6/11/16/18/31/33/45/52/58) compared with those receiving Gardasil 4 (4-valent).

Molecular epidemiology and antimicrobial resistance of invasive non-typhoidal in China, 2007-2016.

Purpose: Human infections caused by invasive non-typhoidal (iNTS) are highly prevalent worldwide. However, data for such infections in China are scarce. This study reports the epidemiology of iNTS in China.

Molecular analysis of the CYP21A2 gene in Chinese patients with steroid 21-hydroxylase deficiency.

Objective: 21-Hydroxylase deficiency (21-OHD) is the most common cause of congenital adrenal hyperplasia (CAH), a family of autosomal recessive disorders involving impaired cortisol synthesis. This study aimed to design a reliable and rational approach for identifying mutations in the CYP21A2 gene and to characterize the molecular basis of 21-OHD in 30 Chinese patients.

Design And Methods: Copy number variations were investigated by multiplex ligation-dependent probe amplification (MLPA).

[Mutational spectrum of phenylalanine hydroxylase gene and identification of novel mutations in patients with hyperphenylalaninemia in Jiangsu province].

Objective: To study the characteristics of phenylalanine hydroxylase (PAH) gene mutations in patients with hyperphenylalaninemia from Jiangsu province by DNA sequencing, and to analyze the spectrum of PAH gene mutations.

Methods: A total of 70 patients and their parents were included in this study. All of the 13 exons and flanking introns of the PAH gene were analyzed with DNA sequencing.

[Development and application of a method for molecular diagnosis of 21-hydroxylase deficiency].

Objective: To develop a method for elucidating genetic basis of 21-hydroxylase deficiency.

Methods: Sanger sequencing of entire 21-hydroxylase coding gene CYP21A2 was carried out to detect point mutations, and multiplex ligation-dependent probe amplification (MLPA) and locus-specific PCR/enzyme restriction method were used to detect large deletions and conversion mutations.

Results: Nine children were analyzed.
