Two colistin resistance-producing strains, isolated from coastal waters in Zhejiang, China: characteristics, multi-drug resistance and pathogenicity.

Introduction: spp. are ubiquitous inhabitants of ecosystems, and many species are opportunistically pathogenic to humans and animals. Multidrug-resistant (MDR) species have been widely detected in hospitals, urban rivers, livestock, and aquatic animals.

Parallel detection of multiple zoonotic parasites using a real-time fluorogenic loop-mediated isothermal amplification-based quadruple-sample microfluidic chip.

Zoonotic parasites pose significant health risks globally. In the present study, we combined a microfluidic chip with loop-mediated isothermal amplification (on-chip LAMP) to detect five zoonotic parasites: , , , , and . This method enabled the simultaneous parallel analysis of five genetic markers from a maximum of four samples per chip.

Memory Retrieval-Extinction Combined With Virtual Reality Reducing Drug Craving for Methamphetamine: Study Protocol for a Randomized Controlled Trial.

Background: Relapse, often precipitated by drug-associated cues that evoke craving, is a key problem in the treatment of methamphetamine use disorder (MUD). Drug-associated memories play a major role in the maintenance of relapse. Extinction training is a common method for decreasing drug craving by suppressing drug-associated memories.

Aqua-(1,10-phenanthroline-κN,N')bis-(trimethyl-acetato)-κO,O';κO-cobalt(II).

In the title compound, [Co(C(5)H(9)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Co(II) atom is coordinated in a distorted octahedral environment by three carboxyl O atoms of two trimethyl-acetate ligands, one aqua O atom and two N atoms from 1,10-phen-anthroline. The crystal structure is stabilized by O-H⋯O hydrogen bonds and π-π stacking inter-actions [inter-planar distance between inter-digitating 1,10-phenanthroline ligands = 3.378 (2) Å].

A comparative clinical study of the effects of the traditional Chinese medicine Jinniu capsules and lofexidine on acute heroin withdrawal symptoms.

Objective: Jinniu capsules, comprised of herbs and marine product extracts, are traditionally used in Chinese medicine. In this randomized multicenter clinical trial we evaluated the efficacy and safety of Jinniu capsules used to treat the symptoms of heroin withdrawal, as compared with lofexidine.

Methods: Two hundred and twelve patients with heroin dependence were randomly assigned to the Jinniu capsule or lofexidine treatment groups during a 10-day double-blind clinical trial.

[Dopamine D2 receptor and transportor [corrected] in the medial prefrontal contex of morphine-induced conditioned place preference in Sprague-Dawley rats].

Objective: To investigate the expression of dopamine D2 receptors (D2R) and dopamine transportors (DAT) located in the medial prefrontal contex (mPFC) in high and low conditioned place preference (CPP) rats, and to unveil the possible mechanism leading to different CPP susceptibilities.

Methods: One hundred and sixty male Sprague-Dawley rats were randomly assigned into an experiment group (n = 130) and a control group (n = 30). The experiment group was re-classified into 2 groups according to CPP values:high preference group (HP group) and low preference group (LP group).

Association of different susceptibilities to morphine with the expression of 5-HTT and 5-HT1AR mRNA in brain regions of SD rats.

Objective: To investigate the possible mechanism for the different CPP susceptibilities.

Methods: Using a conditioned place preference (CPP) model, rats were selected into high and low preference groups. Using in situ hybridization, we examined the mRNA expression of 5-hydroxytryptamine transporter (5-HTT) and 5-hydroxytryptamine 1A receptor (5-HT1AR) in 3 crucial regions in addiction, namely the ventral tegmental area (VTA), the nucleus accumbens (NAc), and the medial prefrontal cortex (mPFC), during the dependence and withdrawal.

[Effect of electroacupuncture on drug-seeking behaviors induced by heroin priming and FosB expression in relevant brain regions].

Objective: To explore the effect of electroacupuncture on heroin seeking behavior and FosB expression in relevant brain regions.

Methods: Rat model of heroin relapse behaviors was developed with progressive fixed ratio program,and model rats were randomly divided into 3 groups: a restraint group, a needle retention group, and a electroacupuncture group. The heroin seeking behavior was elicited by a small dose of heroin.

5-HT2A receptor gene polymorphism and negative symptoms in first episode (drug-naive) Chinese Han nationality individuals with schizophrenia.

Objective: To investigate whether the 5-hydroxytryptamine 2A receptor (5-HT2A) gene T102C polymorphism is associated with the severity symptoms and negative symptoms in the first episode Chinese Han nationality patients with schizophrenia.

Methods: Altogether 201 first episode Chinese Han nationality patients with schizophrenia were enrolled in this study. Genotyping of 5-HT2A gene T102C polymorphism was performed by PCR-RFLP technique.

4,4,5,5-Tetra-methyl-2-(4-pyridyl)-imidazolidin-1-oxyl-3-oxide trichloroacetic acid solvate.

In the title compound, C(12)H(16)N(3)O(2)·C(2)HCl(3)O(2), the imidazolidine ring adopts a twist conformation. The crystal structure is stabilized by inter-molecular O-H⋯N hydrogen bonds.
