In order to evaluate the feasibility of using sp. Y4 as a cadmium (Cd)-reducing bacterial agent in contaminated wheat fields, the changes in the rhizosphere soil microbial community and Cd available state, as well as the content and transport characteristics of Cd in the wheat root, basal node, internode, and grain under the treatment of strain Y4 were tested using microbial high-throughput sequencing, step-by-step extraction, subcellular distribution, and occurrence analyses. The results showed that root application of strain Y4 significantly reduced the root and grain Cd content of wheat by 7.

In order to explore the safety of the soil in the areas where grows,70 surface (0-25 cm) soil samples were collected from the main growing areas of in the eastsouth of Shanxi Province in July 2017. The concentration and composition characteristics of 16 polycyclic aromatic hydrocarbons (PAHs) in the sample soils were analyzed using chemical extraction and gas chromatography-mass spectrometry (GC-MS).

Even fewer studies have been conducted on industrial worker populations. Using a prospective cohort study design, this study collected health examination reports and personal dose monitoring data from 705 industrial irradiation workers who underwent regular physical examinations at Dongguan Sixth People's Hospital.

Radiologists compare the predicted brain age with the ground truth in order to provide a preliminary analysis of AD, which helps doctors diagnose AD as early in its development as possible. In this paper, a transfer learning-based method of predicting brain age using MR images and dataset of a public brain was proposed.

The concentrations of the different PAHs in the soil and plant tissues were analyzed using ultrasonic oscillation extraction and high-performance liquid chromatography-mass spectrometry (GC-MS) analysis methods.

To study the effect of plant protein and animal protein on amino acid metabolism spectrum of Qi and Yin deficiency type 2 diabetic rats. 110 male SD rats were randomly divided into blank group (n=10), diabetic model group (n=20), disease-symptoms group (n=80). The rats of blank group received ordinary feeding, while other groups were fed with high sugar and fat diets.

To investigate the microbial species, amount changes as well as the isolation and identification of domain strains at different fermentation time points of Pinelliae Rhizoma Fermentata, and provide basis for exploring the mechanism of Pinelliae Rhizoma Fermentata processing. Five samples were chosen at the time points (0, 18, 36, 54, 72 h) of Pinelliae Rhizoma Fermentata processing. Bacteria, mold and yeast from the samples were cultured; their colonies were counted, and the dominant strains were isolated and purified.

These seas were found to harbor high levels of fungal diversity, with 816 operational taxonomic units (OTUs) that span 130 known genera, 36 orders, 14 classes and 5 phyla. Ascomycota was the most abundant phylum, containing 72.

Objective: To study the effects of caffeine citrate on myelin basic protein (MBP) expression in the cerebral white matter of neonatal rats with hypoxic-ischemic brain damage (HIBD) and the related mechanism.
Methods: Forty-eight seven-day-old Sprague-Dawley neonatal rats were randomly assigned to 3 groups: sham operation (n=16), HIBD (n=16) and HIBD+caffeine citrate (n=16). The rats in the HIBD and HIBD+caffeine citrate groups were subjected to left common carotid artery ligation, and then were exposed to 80 mL/L oxygen and 920 mL/L nitrogen for 2 hours to induce HIBD.

Objective: To study risk factors for periventricular-intraventricular hemorrhage (PVH-IVH) in premature infants treated with mechanical ventilation.
Methods: A total of 205 premature infants who were admitted to the neonatal intensive care unit (NICU) and treated with mechanical ventilation between January 2009 and December 2011 were enrolled. They were classified into PVH-IVH and non-PVH-IVH groups according to the results of head ultrasonography performed at 3 to 7 days after birth.
