[Influencing Factors of Cadmium Content in Wheat Grain: A Meta-analysis and Decision Tree Analysis].

Rapid urbanization, industrialization, and agricultural intensification have resulted in serious soil problems, such as soil acidification and cadmium pollution, affecting food security and human health. Wheat is the second largest food crop in China and has a strong accumulation capacity for cadmium. Understanding the influencing factors of cadmium content in wheat grain is crucial to realize the safe production of wheat.

Sex-specific differences in the gut microbiota and fecal metabolites in an adolescent valproic acid-induced rat autism model.

Background: Alterations in the microbiota-gut-brain axis are associated with the onset of autism spectrum disorder (ASD). Numerous studies have reported that the gut microbiota (GM) is significantly altered in individuals with ASD and animal models of ASD. However, few studies have focused on sex-specific differences in the GM and fecal metabolites of ASD.

Clinical Characteristics of Visual Dysfunction in Carbon Monoxide Poisoning Patients.

Purpose: The aim of the present study was to analyze the clinical characteristics of visual dysfunction in patients with carbon monoxide (CO) poisoning.

Methods: A total of 436 patients with CO poisoning were enrolled in our hospital from October 2012 to December 2018, including 193 patients with moderate poisoning (MP group), 165 with severe poisoning (SP group), and 78 with delayed encephalopathy (DE group). The clinical characteristics of visual dysfunction in patients with CO poisoning were analyzed through the collection of medical history, regular physical examination, brain magnetic resonance imaging (MRI), ophthalmological examination, the National Eye Institute Visual Function Questionnaire (NEI-VFQ), and its influencing factors.

Microfluidic preparation of flexible micro-grippers with precise delivery function.

We used microfluidic technology for preparing gas-liquid Janus emulsions; we firstly proposed a one-step preparation method of micro-grippers and then characterized the function of oriented and precise delivery behavior. Because of the enrichment of Fe3O4 nanoparticles, the micro-gripper can reach a speed of 1.5 mm s-1 driven by a magnetic field.

Three new species of Calocybe (Agaricales, Basidiomycota) from northeastern China are supported by morphological and molecular data.

Three new species, Calocybe aurantiaca, C. convexa, and C. decolorata, are described based on collections made in Shenyang City, Liaoning Province, China.

The NGF point-injection for treatment of the sound-perceiving nerve deafness and tinnitus in 68 cases.

Objective: To observe the therapeutic effects of the point-injection with nerve growth factor (NGF) for the sound-perceiving nerve deafness and tinnitus.

Methods: The 140 cases in this series were randomly divided into a treatment group of 68 cases treated by NGF injection at the points of Yifeng (TE 17) and Wangu (GB 12), and a control group of 72 cases orally taking Xibiling and adenosine triphosphate (ATP) and intramuscular injection with VB1 and VB12.

Results: The total effective rate was 78.

[Factors affecting the outcome of extracorporeal shockwave lithotripsy for upper urinary tract stones].

Objective: To investigate the factors affecting the efficacy of extracorporeal shockwave lithotripsy (ESWL) for upper urinary tract stones.

Methods: Between January 2003 and January 2006, 366 patients with upper urinary tract stone underwent ESWL, and the results were identified by regular KUB/IVU or ultrasonography and evaluated 3 months after the treatment. The treatment success was defined as complete clearance of the stones without residual fragments.

25-gauge transconjunctival sutureless vitrectomy system in the surgical management of children with posterior capsular opacification.

Purpose: To evaluate the safety and efficacy of the 25-gauge transconjunctival sutureless vitrectomy (TSV) system in the surgical management of posterior capsular opacification (PCO) in pseudophakic children.

Methods: Pars plana membranectomy was performed for PCO in 10 pseudophakic eyes of six children (mean age 35.1 +/- 37.

[WEIDA LMW-1000 magnetic resonance imaging system communication with Windows 98 computer].

This paper introuduces two ways of WEIDA LMW-1000 Magnetic Resonance Imaging System's communication with Windows 98 computer. It has a practical value to the improvement of the system's operation interface.

Soluble expression and characterization of a GFP-fused pea actin isoform (PEAc1).

A pea actin isoform PEAc1 with green fluorescent protein (GFP) fusion to its C-terminus and His-tag to its N-terminus, was expressed in prokaryotic cells in soluble form, and highly purified with Ni-Chelating Sepharose Fast Flow column. The purified fusion protein (PEAc1-GFP) efficiently inhibited DNase I activities before polymerization, and activated the myosin Mg-ATPase activities after polymerization. The PEAc1-GFP also polymerized into green fluorescent filamentous structures with a critical concentration of 0.
