Retrospective Analysis of Death Cases of Oral Diphenidol Hydrochloride Poisoning.

Objectives: To explore the characteristics of postmortem examination, chemical examination and scene investigation of deaths caused by oral diphenidol hydrochloride poisoning, and so as to provide a reference for proper settlement and prevention of such deaths.

Methods: The data of 22 deaths caused by oral diphenidol hydrochloride poisoning in a city from January 2018 to August 2020 were collected, including case details, scene investigations, autopsies, chemical examinations and digital evidence. Thirty-one cases of deaths caused by oral diphenidol hydrochloride poisoning reported in previous literature were also collected.

[Low Temperature Ammonia Nitrogen Removal from an Iron, Manganese, and Ammonia Groundwater Purification Process with Different Concentrations of Iron and Manganese].

In a groundwater plant, removal of iron, manganese, and ammonia nitrogen was performed via a purification process using a filter column at a low temperature (5-6℃). Iron, manganese and ammonia [Fe(Ⅱ) 0-19.26 mg·L, Mn(Ⅱ) 0.

[Effect of Filter Speed and Water Quality on Ammonia Removal in Groundwater Containing Iron, Manganese, and Ammonia at Low Temperature].

In a groundwater plant we carried out a process operation test of biological removal of iron and manganese nitrification coupled with completely autotrophic ammonium removal over nitrite (CANON) (Fe(Ⅱ) 2.91-6.35 mg·L, Mn(Ⅱ) 0.

Isolation and characterization of microsatellite loci for (Rosaceae).

Premise Of The Study: Microsatellite primers were developed in (Rosaceae), a relict flora endemic in arid areas of the Asian interior, to investigate the genetic diversity, phylogeography, population structure, and history of the species.

Methods And Results: Fifty-one microsatellite loci, including di-, tri-, and tetranucelotide repeats, were identified using transcriptome sequencing and bioinformatic screening. The number of alleles ranged from seven to 11 and the levels of observed and expected heterozygosity ranged from 0.

Simulation of biatrial conduction via different pathways during sinus rhythm with a detailed human atrial model.

In order to better understand biatrial conduction, investigate various conduction pathways, and compare the differences between isotropic and anisotropic conductions in human atria, we present a simulation study of biatrial conduction with known/assumed conduction pathways using a recently developed human atrial model. In addition to known pathways: (1) Bachmann's bundle (BB), (2) limbus of fossa ovalis (LFO), and (3) coronary sinus (CS), we also hypothesize that there exist two fast conduction bundles that connect the crista terminalis (CT), LFO, and CS. Our simulation demonstrates that use of these fast conduction bundles results in a conduction pattern consistent with experimental data.

[Formaldehyde inhalation may damage olfactory bulb and hippocampus in rats].

Objective: To investigate the effects of formaldehyde inhalation on the morphological damage, and Glu, GABA and NOS contents in olfactory bulb and hippocampus of rats.

Methods: Twenty SD rats were equally divided into two groups: rats in the control group inhaled fresh air, while the animals in experimental group were exposed to the air containing formaldehyde (12.5 mg/m(3), 4 h/d) for 7 days.

Molecular mechanism for conformation mobility of the active center of glucose oxidase adsorbed on single wall carbon nanotubes.

A critical issue in bioelectrochemical applications, that use electrodes modified by nanomaterials, like enzyme sensor modified by Single Wall Carbon Nanotubes (SWCNTs), is to ensure high activity of the active center of an immobilized enzyme protein. Since Flavin Adenine Dinucleotide (FAD) along with other amino residues, including His559, Glu412 and His516, constitute the active center of the catalytic site conformation of which could determine the activity of enzyme, it is important to understand the molecular mechanism of their mobility and the potential impact on the catalytic activity while GOx is immobilized on SWCNTs. However, this dynamic mechanism still remains blurry at the atomic level due to the active center being embedded in the apo-GOx and the limitations of appropriate experimental methods.

Conformational Mobility of GOx Coenzyme Complex on Single-Wall Carbon Nanotubes.

A critical issue in bioelectrochemical applications that use electrodes modified by Single Wall Carbon Nanotubes (SWCNTs) is to ensure high activity of the catalytic site of an immobilized enzyme protein interacting with nanomaterials. Since Flavin Adenine Dinucleotide (FAD), a coenzyme of glucose oxidase (GOx), is the active center of the catalytic site, conformation of which could determine the activity of enzyme, it is important to understand the dynamic mechanism of its conformational mobility while GOx is adsorbed on SWCNTs with multiple orientations. However, this dynamic mechanism still remains unclear at the atomic level due to the coenzyme being embedded in the apo-GOx and the limitations of appropriate experimental methods.
