To enhance the interfacial interaction of activated carbon (AC) with volatile organic compounds (VOCs), the AC surface was modified by depositing metal oxide nanoparticles via an evaporation-induced self-assembly (EISA) method. Taking acetone, toluene and methanol as adsorbates, both dynamic and...

Carbon oxidation has two stages, the first is the formation of surface oxides and the second is the gasification of the surface oxides to CO2. Calcium carbonate (CaCO3) was used to catalyze the gasification of the surface oxides. The catalytic effect of on graphite oxidation and its catalytic me...

Benzodiazepines (BDZs) are widely prescribed in older people. The aims of the study are to assess the prevalence of inappropriate prescription of BZDs and the associated factors in acutely hospitalized older patients. Patients aged 65 years or more hospitalized from 2010 to 2017 in more than 100...

ObjectivesTo examine the association of benzodiazepines and anticholinergic drug usage with the risk of dementia.

IntroductionAlcohol withdrawal treatment varies widely. Benzodiazepines are the standard of care, with rapid onset and long durations of action. Recent drug shortages involving IV benzodiazepines have required incorporation of alternative agents into treatment protocols. Phenobarbital has simila...

An important predictor of opioid overdose is co-use of benzodiazepines, which are often prescribed for anxiety. Coping with anxiety may be particularly difficult among individuals with a history of abuse, as it is often linked to higher pain severity and poorer coping skills. We explored whether...

Everyday activity is based on a subtle equilibrium of excitatory and inhibitory neuronal systems. The most prominent players in neuronal inhibition are synaptic and extrasynaptic GABAA receptors. Benzodiazepines are popular drugs that act as positive allosteric modulators of a subset of these re...

ContextPatients with cancer often experience distressing symptoms such as anxiety or dyspnea, which can be managed with benzodiazepines; however, concerns regarding the impact of these drugs on survival may dissuade prescribing and compliance.

There are currently new drugs being developed that have benzodiazepine properties. This review will examine remimazolam, 3-hydroxyphenazapam, adinazolam, clonazolam, and deschloroetizolam as well as other novel agents. All benzodiazepines are protein bound and only moderately lipid soluble. In a...

The abuse of new psychoactive substances (NPS) has been increasing dramatically since the late 2000s worldwide. Between 2009 and 2017, a total of 803 individual NPS were reported to the United Nations Office of Drugs and Crime by 111 countries and territories. Although the most popular compounds...

BackgroundBenzodiazepine misuse is a growing public health problem, with increases in benzodiazepine-related overdose deaths and emergency room visits in recent years. However, relatively little attention has been paid to this emergent problem. We systematically reviewed epidemiological studies ...

The chemical and electrochemical reduction of the niobocene dichlorides [Nb(η5-C5H4SiMe3)2Cl2]1, [Nb(η5-C5Me5)2Cl2] 2 and [Nb(η5-C5Me4Et)2Cl2] 3, in the presence of carbon dioxide has been investigated. Formation of compounds of the type [Cp2Nb(CO2)] and [Cp2(∗)NbCl(CO2))] 1 has been establis...

Oxidations of 1 using copper(II) dichloride and silver tetrafluoroborate produces a niobocene dichloride cation in [Nb(η5-C5H4But)2Cl2][CuCl2] 1, and a mixed halide cation in [Nb(η5-C5H4But)2(Cl)F][BF4] 2.

The infrared and Raman spectra of niobocene dichloride were recorded and briefly discussed. The results were compared with the infrared spectra of niobocene di-iodide. The assignment of both infrared and Raman bands was proposed.

Trans-Dimethylammonium bis(oxalato)diaquaruthenate(III) tetrahydrate, trans-[(CH3)2NH2][Ru(C2O4)2(H2O)2]·4H2O, was synthesized by diffusion of dimethylamine (from dimethylformamide) into a refluxed aqueous solution of diruthenium(II,III) tetraacetate and oxalic acid. The structure of the comple...

The inorganic dye, ruthenium red, is an ammoniated form of ruthenium oxychloride. The purity of commercial samples of ruthenium red has been confused as commercial vendors often provide a “dye content” figure for their product, which some investigators have equated with purity. However, dye co...

Iron-doped titania nanobelts were prepared by a one-step alkaline hydrothermal method with use of iron(III) nitrate for in-situ Fe doping. The synthesis ensured Fe substitution for Ti in the oxide lattice and anatase growth. The Fe addition increased electronic donor density and induced a negati...

With increasing trend in industrialization, heavy metals possess a great threat to the environment due to their discharge in water and wastewater above permissible limits. Heavy metals have toxic effects on human and environment. However, advancement in newly budding and fangled nanotechnology o...

Thallium (Tl) contamination caused by the industrial wastewater leakage has become a serious environmental problem due to thallium's high toxicity. In this study, a novel titanium‑iron magnetic nano-sized adsorbent was synthesized and applied for the effective removal of thallium(I). The ph...

The effectiveness of the current UK iron oxide powder suspension formulation, ‘C-IOPS-09’ (Triton X-100 based), for fingermark or latent fingerprint visualization is shown to be affected by variations between batches of the recommended iron oxide powder from Fisher Scientific (I/1100/53). When...
