Halogen engineering of organic-inorganic hybrid perovskites displaying nonlinear optical, fluorescence properties and phase transition.

In order to meet the needs of social development, increasing research attention has been paid to multifunctional molecular-based phase-transition materials. The traditional phase-transition materials with a single functional property can be transformed into magnificent ones by adding additional functional properties-for instance photoluminescence and magnetic order- because having two or more functional properties simultaneously greatly broadens the fields of their applications. At present, there are very few multifunctional phase-transition materials showing excellent performance, and the crystal structure design and performance optimization of materials still need to be studied in depth.

Use of the alkaline comet assay for monitoring genotoxic effects of arsenic in human populations.

The alkaline comet assay has been widely used to determine genotoxicity in human populations exposed to arsenic. The sample sizes of earlier studies were usually small, and inconsistent results were found. Meta-analyses can merge the results of multiple studies of the same type and increase the credibility of the conclusion by increasing the sample size.

Sea Voyage Training and Motion Sickness Effects on Working Ability and Life Quality After Landing.

The effects of seasickness on working performance during motion exposure have been reported, while the aftereffects on working ability and life quality decline (WLD) still remain unclarified. Two cohorts of healthy male Chinese subjects received either a single (SSV) or repeated (RSV) sea voyage training program on different vessels. A seasickness incidence (SSI) questionnaire was administered to assess the prevalence of seasickness symptoms (vomiting, nausea, other, or no symptoms).

Micronucleus assay for monitoring the genotoxic effects of arsenic in human populations: A systematic review of the literature and meta-analysis.

The micronucleus (MN) assay has been used to determine the potential genotoxic effects in human populations exposed to arsenic. Some of these studies found an increase in MN frequency among exposed individuals, but others found no increase or inconclusive results. Thus, the main purpose of this current study was to investigate whether MN can be used as a biomarker for the arsenic exposure, as well as whether or not the different cell types that have been used to monitor MN frequency differ in their sensitivity to upon arsenic exposure.

Multiplex analysis of serum hormone and cytokine in patients with cervical cOPLL: towards understanding the potential pathogenic mechanisms.

Cervical ossification of the posterior longitudinal ligament (cOPLL) is one of the major causes of myelopathy. However, the mechanism underlying remains elusive. In the present study, using MILLIPLEX magnetic bead panel, we investigated four serum hormones and six serum cytokines in cOPLL patients and healthy subjects.

[The Real World Study on Evaluating the Effect of Chinese Medicine Combined Western Medicine in Treating Rheumatoid Arthritis].

Objective To observe the curative effect of Chinese medicine (CM) combined West- ern medicine (WM) in treating rheumatoid arthritis (RA) patients. Methods Totally 351 RA patients were allocated into two groups by their willingness, 52 cases in the control group and 299 cases in the combination group. Treatment of WM mainly included non-steroidal anti-inflammatory drugs, glucocorti- coids, and anti-rheumatic drugs.

Inhibitory effect of Zanthoxylum bungeanum seed oil on ovalbumin‑induced lung inflammation in a murine model of asthma.

The present study aimed to investigate the therapeutic efficacy of Zanthoxylum bungeanum seed oil (Z. seed oil) to alleviate airway inflammation in asthmatic mice. The asthmatic mice were treated with vehicle, ovalbumin (OVA), or OVA + Z.

Motion Sickness and Resting Energy Expenditure in Chinese Male Adults.

Background: Motion sickness can influence energy homeostasis by enhancing thermolysis. This study tested the hypothesis that resting energy expenditure (REE), as the major component of thermogenesis, might also play a role during motion sickness.

Methods: The effect of seasickness on REE at sea was examined in 71 healthy Chinese male volunteers.

Motion Sickness: Current Knowledge and Recent Advance.

Motion sickness (MS) is a common physiological response to real or virtual motion. Numerous studies have investigated the neurobiological mechanism and the control measures of MS. This review summarizes the current knowledge about pathogenesis and pathophysiology, prediction, evaluation, and countermeasures of MS.

Differential Gene Expression Profile in the Rat Caudal Vestibular Nucleus is Associated with Individual Differences in Motion Sickness Susceptibility.

Objective: To identify differentially expressed genes associated with motion sickness (MS) susceptibility in the rat caudal vestibular nucleus.

Methods: We identified MS susceptible (MSS) and insusceptible (inMSS) rats by quantifying rotation-induced MS symptoms: defecation and spontaneous locomotion activity. Microarray analysis was used to screen differentially expressed genes in the caudal vestibular nucleus (CVN) after rotation.

Temporal change in NMDA receptor signaling and GABAA receptor expression in rat caudal vestibular nucleus during motion sickness habituation.

Repeated exposure to a provocative motion stimulus leads to motion sickness habituation indicative of the existence of central processes to counteract the disturbing properties of the imposed motion. In the present study, we attempt to investigate whether NMDA and GABA(A) receptors in rat caudal vestibular nucleus neurons are involved in motion sickness habituation induced by repeated Ferris-wheel like rotation in daily session (2h/d). We showed that defecation response increased and spontaneous locomotion decreased within 4 sessions (sickness phase).

Decreased Fos protein expression in rat caudal vestibular nucleus is associated with motion sickness habituation.

We investigated the temporal change of Fos protein expression in the caudal vestibular nucleus of rats exposed to daily 2-h Ferris-wheel like (FWL) rotation. Repeated rotation (2h daily for 14 consecutive days) caused an initial increase in defecation, followed by a gradual decline back to the baseline level after 8 rotation sessions. Unlike defecation, the Kaolin consumption of rats showed a bitonic function during the daily rotation sessions (2h daily for 33 consecutive days) and finally recovered to the baseline after about 31 sessions.

[Association between incidence of idiopathic ventricular tachycardia and risk factors with short-term effects: a case-crossover study].

Objective: To explore the transient risks regarding idiopathic ventricular tachycardia (IVT).

Methods: A symmetric bidirectional case-crossover design was used to estimate the short-term risk of IVT. In the case-crossover design each case served as its own matched control while case-period were compared to two control-periods, 7 days before and after the case-period.

Excitatory pathways from the vestibular nuclei to the NTS and the PBN and indirect vestibulo-cardiovascular pathway from the vestibular nuclei to the RVLM relayed by the NTS.

Previous studies have confirmed the existence of vestibulo-sympathetic pathways in the central nervous system. However, the exact pathways and neurotransmitters underlying this reflex are unclear. The present study was undertaken to investigate whether the vestibulo-cardiovascular responses are a result of activated glutamate receptors in the caudal vestibular nucleus.

[Studies on the anaerobic phased solid digester system for municipal solid waste (MSW) treatment].

Through analyzing and detecting the leaching pollutant (COD) in two bioreactors, anaerobic phased solid digester system and leachate direct-recirculating landfill, the changing rule of municipal solid waste and the characteristics of methanogenesis were studied. The results showed that anaerobic phased solid digester system accelerated the process of degrading municipal solid waste and stabilizing landfill site. The relationship between the leaching pollutant (COD) and refuse age was logarithmic linear correlation.
