“Introduction There has been in recent years a growing

awareness and media coverage about psychological harassment at work and its devastating impact on victims, such as stress or burnout syndromes (Tarquinio et al. 2004) (Bowling and Beehr 2006; Hansen et al. 2006). Physical forms of workplace violence have been investigated as well, but there has been comparatively little

research on consequences of physical assaults against workers. As a matter of fact, many studies and reviews have concentrated on identifying risk factors and assessing the prevalence of this phenomenon (Barling et al. 2009; Dillon 2012). The healthcare setting has drawn particular attention (Gillespie et al. 2010; Kowalenko et al. 2012; Taylor and Rew 2011). Acts of physical violence at work are defined as assaults carried out by one or several perpetrators, by members of the same organization as the victim (internal violence) or by “outsiders” CHIR-99021 supplier (external violence) such as clients and patients. External forms of physical violence are more common than internal ones and affect more often, but not exclusively, “frontline staff” in the services industry (European Foundation for the Improvement of Living and Working Conditions 2007). Workplace violence seems to become more pervasive throughout the world and represents a growing health and security challenge for many organizations. An increase in the prevalence of physical workplace violence (from 4 to 6 % in the past 12 months) was reported in the European Working Conditions Surveys from 1995 to 2005 in Northern Europe. The same study showed that external physical violence was more frequent than internal physical violence. Substantial differences were observed according to the type of occupation.

“Background The metal nanoparticles (NPs) are powerful products of nanotechnology, providing broad variety of applications in life science [1, 2]. For example, drug delivery, cellular imaging, and biosensing have been extensively described [3–6]. The chemical versatility of metal NPs holds the potential to outclass in a number of applications [2]. These unique properties and applications of metal NPs are well reviewed [7–9]. Platinum is used in various applications such as catalysts in many organic reactions [10, 11], preparation of organic dyes [12], and biomedical applications [13,

14]. For example, the Pt NPs were employed for successful photothermal treatment of Neuro 2A cancer cell by using irradiation with 1,064 nm near-infrared pulse wave Verteporfin and the Nd YAG laser set at 3 W for 480 s. The Pt NPs increased 9°C in temperature leading to effective Selleck BIBF 1120 photothermal killing of cancer cells [15]. The Pt composite materials have gained much attention due to their good multifunctions [16, 17]. Pt NPs-chitosan composite particles have been extensively studied over the last decade [18, 19], and Pt NPs-chitosan composite bubbles are one of the most emerging and intriguing topics [20, 21]. Bubble particles have import features entrapping air bubbles inside. Due to their low density, bubble particles can float on liquid

surface for specific applications. They can also be applied as novel vehicles for ultrasound-mediated imaging and targeted drug delivery followed by burst release [22–27]. Besides, bubble particles can be utilized as absorbers

to facilitate adsorption of substrates due to a high-surface area. Pt NPs-chitosan composite bubbles can be applied in controlled release and tissue engineering; however, chitosan carrier substrates will disintegrate and dissolve in acid solution such as gastric juices. Therefore, Pt NPs-chitosan composite bubbles are limited in acidic condition. Fortunately, C-X-C chemokine receptor type 7 (CXCR-7) alginate polymer provides a solution to overcome this problem. Alginate polymer has a dense structure to pass the acid solution. To our best knowledge, Pt NPs-alginate composite (Pt NPs@alginate) bubbles are seldom reported in literatures, and they can provide applications for wide pH ranges. By extending our previous works to prepare uniform alginate particles [28–31] and alginate bubbles [32], this work further develops a novel one-step method to fabricate composite Pt NPs@alginate bubbles through a simple chemical reaction. The Pt NPs and bubbles within alginate particles are investigated and characterized. The manufactured alginate products will provide great promise for multifunctional applications. Methods Materials Alginic acid sodium salt (Na-alginate, brown algae with viscosities 150 cp and 350 cp in 2% (w/v) solution at 25°C) and dihydrogen hexachloroplatinate (IV) MLN8237 nmr hexahydrate, ACS, Premion, 99.

“Background Helicobacter pylori infection increases the risk of peptic ulcers and gastric adenocarcinoma of

the human stomach [1–3]. H. pylori adherence to the gastric epithelium and deliver effectors to induce inflammation [4, 5]. One of the best-studied adhesins is the blood group antigen binding adhesin (BabA), which binds Lewis b (Leb) and related ABO antigens [6, 7]. Putative adhesin, BabB, is encoded by babB, which shares Etofibrate nearly identical N- and C-terminal sequences with babA[7, 8]. The reversed chromosomal locations of babA and babB between strain J99 and 26695 prove the recombination events between these two genes [9, 10]. The two genes also show both geographic and allelic variation [11]. Moreover, the duplication of babA or babB gene is mediated by gene conversion between the different chromosomal loci [12–14]. Bäckström et al. [14] demonstrated that the silent babA gene of a Leb-nonbinding strain can be activated by recombination into the babB gene.

The studies on the applications of konjac glucomannan have been e

The studies on the applications of konjac glucomannan have been extended greatly from food and food additives to various fields [28, 29]. Herein, we explore the use of KGM in the preparation of nanosized materials and thus further promote its application in nanotechnology. BIIB057 In the present study, konjac glucomannan was introduced for the facile synthesis of gold nanoparticles, both as reducing agent and stabilizer (Figure  1). The synthesized gold nanoparticles were characterized in detail by transmission electron microscopy (TEM), X-ray diffraction (XRD), dynamic light

scattering (DLS), and Fourier transform infrared (FTIR) spectroscopy. Furthermore, the catalytic activity of the gold nanoparticles was investigated by the reduction of p-nitrophenol (4-NP) to p-aminophenol (4-AP). It should be noted that Konjac glucomannan, as an abundant natural polysaccharide, could be easily gained from Konjac plant tubers at low cost. Meanwhile, the gold nanoparticles reduced in the aqueous KGM solution exhibit great stability and dispersibility

due to specific properties of KGM. Figure 1 Schematic plot illustrating the formation and stabilization of AuNPs using konjac glucomannan. Methods Materials Chloroauric acid (HAuCl4 · 4H2O, 99.9%) was purchased from Aladdin (Shanghai, China). Purified konjac glucomannan was obtained from Shengtemeng Konjac Powder Co. (Sichuan, China). All solutions were prepared in double-distilled water, and all glassware

used was rinsed with aqua A-1155463 price regia solution (HCl/HNO3, 3:1) and then washed with double-distilled water before use. All other common reagents and solvents used in this study were of analytical grade. Synthesis of AuNPs in aqueous solution with KGM KGM powders (0.25 g) were Sclareol dispersed in double-distilled water (100 mL) by stirring for 1 h at room temperature, and then the solution was held at 80°C for 1 h. The preparation of gold nanoparticles is quite straightforward. In a typical preparation, sodium hydroxide solution (0.4 mL, 1 M) was added to KGM solution (20 mL, 0.25 wt%) under stirring, and then aqueous HAuCl4 (2 mL, 10 mM) solution was introduced. The mixture was incubated at 50°C for 3 h. The obtained gold nanoparticles were collected by centrifugation and washed thoroughly with DI water. Characterization All AP26113 molecular weight UV-visible (UV-vis) spectra were recorded on a Pgeneral TU-1810 spectrophotometer (Purkinje Inc., Beijing, China) with 1-cm quartz cells. At different time intervals, aliquots of the solution were taken out and the samples were cooled to ambient temperature and then tested immediately. The morphology of the prepared gold nanoparticles in KGM solutions was examined with a JEOL JEM-2100 F transmission electron microscope (TEM, JEOL Inc., Tokyo, Japan) operated at an acceleration voltage of 200 kV.

The BIND and HPRD interactions are shown in dashed lines, whereas the HIV-1-human protein interactions in solid lines with colored triangles representing different interaction types.

It has been hypothesized that cysteamine, which is a chemical pre

It has been hypothesized that cysteamine, which is a chemical precursor of the pantetheine moiety of coenzyme A, was formed in the primitive oceans from ethylene sulfide and ammonia or from ethylene imine and hydrogen sulfide (Keefe et al. 1995). However, our results suggest that cysteamine could have also formed readily from electric discharges. The recently discovered enzymatic conversion of cysteate into sulfopyruvate in the biosynthesis of coenzyme M (2-mercaptoethanesulfonic acid, HSCH2CH2SO3H) in Methanosarcina acetivorans (Graham et al. 2009) supports the idea that products of cysteine degradation and

other sulfur-bearing organic compounds SAHA HDAC cost of prebiotic origin may have been involved in early biological processes. The selection of the two thio-amino acids present in proteins is likely the outcome of a combination of their availability coupled with their functional utility (Cleaves 2010; Weber and Miller 1981). It has been suggested that cysteine could be an evolutionary replacement of an ancestral sulfhydryl-containing coenzyme (White 1982). However, it is possible that cysteine was first Selleck BI 10773 incorporated into proteins because of its ability to form RNA-recognizing zinc-fingers, to bind to Fe/S clusters and to dimerize and covalently link to form disulfide bonds that play a key role in maintaining functional three-dimensionally folded

protein structures. In addition to its role as a building block in proteins, methionine is the immediate selleckchem precursor

of S-adenosylmethionine (SAM), the major methyl-group donor in transmethylation reactions in contemporary biochemistry. It has been proposed that methyl group transfer from SAM to amines may be vestigial of prebiotic Oxymatrine methylation reactions involving formaldehyde (Waddell et al. 2000). However, the possibility that ribonucleotide-like coenzymes are remnants of an ancestral stage in which ribozymes played a more conspicuous role in metabolism (Orgel and Sulston 1971; White 1976) suggests that methionine may have been first incorporated into biological systems because of its involvement in methyltransferase activities that evolved in a primordial RNA-dependent world. In other words, it is possible that methionine was initially incorporated into the RNA world as a cofactor.
