Plant health is intricately linked to crop quality, food security and agricultural productivity. Obtaining accurate plant health information is of paramount importance in the realm of precision agriculture. Wearable sensors offer an exceptional avenue for investigating plant health status and fundamental plant science, as they enable real-time and continuous in-situ monitoring of physiological biomarkers.

This study investigated whether motherwort injection, a traditional Chinese medicine preparation, was more effective than intramuscular (IM) oxytocin for preventing postpartum hemorrhage (PPH) in a real-world setting when intravenous (IV) oxytocin is administered. We conducted an active-controlled, propensity-score matched cohort study using an established pregnancy registry database.

An empirical study is promptly needed to reliably assess the causal effects of the mobility restriction. The purpose of this study was to quantify the causal effects of human mobility restriction on the spread of COVID-19.

This study aimed to assess HPV and HPV vaccine knowledge, and to evaluate the effect of a school-based educational intervention, immediately and one year later, on HPV knowledge and vaccine acceptability among adolescents in mainland China.
Methods: A school-based interventional follow-up study was conducted in seven representative cities in mainland China from May 2015 to May 2017.
Objective: To study the association between prepregnancy subnormal body weight and obstetrical outcomes after autologous in vitro fertilization (IVF) cycles.
Design: Systematic review and meta-analysis.
Setting: Not applicable.

Background: miR-30a is a microRNA associated with the progression of malignant tumors such as gastric cancer, colon cancer, prostate cancer, and lung cancer, and can regulate the proliferation and migration of breast cancer (BC) cells in vitro. However, its expression, function, clinical significance and relationship with the Wnt/β-catenin pathway in human BC were still unclear.
Methods: Immunohistochemistry, Western blotting and real-time quantitative PCR (RT-qPCR) were used to measure the expressions of miR-30a and β-catenin in 114 pairs of human BC tumor tissues and adjacent normal tissues which were collected from March 2014 to October 2015.
Background: Little is known about the knowledge and attitudes towards human papillomavirus (HPV) and its vaccines among adolescents in mainland China. Also, limited information has been available on how to improve their knowledge and willingness towards HPV and its vaccines to ensure a successful vaccination program in the future.
Methods: This was a school-based interventional follow-up study.
Malignant peritoneal mesothelioma (MPeM) is an incurable cancer with poor prognosis, and several biomarkers have been suggested for screening of MPeM. The aim of our study was to evaluate the prognostic significances of IMP3 and Fli-1 in MPeM. Diagnostic biopsies of 44 MPeM patients were centrally collected and were immunohistochemically analyzed for expression of IMP3, Fli-1, and Ki-67.

The polymorphisms of leptin (LEP) and leptin receptor (LEPR) may be associated with breast cancer by regulator of adipose tissue mass and tumor cell growth. A total of 794 cases and 805 matched controls were sequentially enrolled.

However, the molecular and cellular mechanisms underlying the pathogenesis of pulmonary fibrosis remain to be fully elucidated. The contribution of the phosphoinositide 3‑kinase (PI3K)/protein kinase B (Akt) pathway in fibrotic processes remains to be investigated.

However, its reduced osteoinductive ability may limit the utility of CPC. To increase its osteoinductive potential, this study aimed to prepare tissue-engineered CPC and evaluate its use in the repair of bone defects.

Objective: To evaluate the osteogenic functions of injectable biological bone cement during repairing inclusive bone defects in rabbit femoral condyles.
Methods: Encapsulated rhBMP-2 gene modified rabbit bone mesenchymal cells (BMSCs) were seeded into calcium phosphate cement (CPC) to prepare injectable biological bone cement. The live/dead cell ratio was detected by calcein-AM/ethidium homodimer staining and cement microstructure examined by electron microscope.
Objective: To screen differentially expressed brain proteins with proteomic method in cerebral cortex of neonatal rats with congenital hypothyroidism.
Method: From the 13th day of gestation, pregnant Wistar rats from the experimental group were given intragastrically with 2.5 ml of 1% propylthiouracil daily.
Background: Reversal of liver fibrosis is one of the key steps in the prevention and treatment of alcoholic liver disease (ALD), but the mechanism is unknown. This study was to investigate the effects of the Chinese medicine Kang Xian Fu Fang I (KXI) on prophylaxis and treatment of ALD in rats and its possible mechanism of action.
Methods: Eighty male Wistar rats were randomly divided into four groups: normal control; ALD model; treatment of ALD with KXI; and prophylaxis of ALD by KXI.

We have developed technologies for creating saturating libraries of sequence-defined transposon insertion mutants in which each strain is maintained. Phenotypic analysis of such libraries should provide a virtually complete identification of nonessential genes required for any process for which a suitable screen can be devised. The approach was applied to Pseudomonas aeruginosa, an opportunistic pathogen with a 6.

Objective: To investigate the role of hepatic and gastric alcohol dehydrogenase (ADH) in different pathologic stages of alcoholic liver disease (ALD).
Methods: Thirty-nine Wistar rats were divided randomly into two groups: model group (24) and control group (15). The ALD model was established by infusing alcohol into the stomach.
