Plastic is a ubiquitous material in our life, and its durability represents a great problem for the environment. Several studies reported the occurrence of plastic litter in different environmental compartments and, consequently, numerous efforts are currently focused on how improving its recycling process and produce environmentally friendly solutions. In recent years, biodegradable polymers/plastics (BPs) have been proposed to reduce environmental impacts in specific applications (e.g., when conventional plastics are difficult or expensive to remove from the environment). Their wide use in commercial products, especially in the packaging sector, is causing new pollution alarm. Research studies are ongoing to improve BPs manufacturing and characteristics, but few data are reported about their behavior and toxicity into the marine environment. This paper reviewed the current state of the art highlighting that, even though the degradation of BPs in simulated or real marine environments is quite investigated, only eleven papers reported their effects on marine organisms (e.g., behavioral and oxidative stress and potential cascading effects on marine ecosystems). Presently, the main benefits of BPs are linked to waste management (including collection and recycling of organic waste). Due to the existing knowledge gaps, BPs cannot be deemed yet as a solution to marine plastic pollution.The present paper is dedicated to analyze non-hazardous kinetic behaviour and modelling of green synthesized cobalt nanocatalyst (CoNCs), using an Artificial Neural Network (ANN). In order to supplement the trace metal in other applications, CoNCs were rapidly synthesized with a Cobalt sulphate solution at room temperature between 30 and 35 ºC at pH 7.2 under less reaction time. The Levenberg - Marquardt algorithm (LM) is used to investigate the experimental values by applying ANN. The results of variance using logistic ANN model depicts that the maximum nanoparticles were synthesized at its optimized stipulation of 0.5 h stirring time, 25 mL volume of extract and 20 mL volume of cobalt sulphate. The developed ANN model proved to be an efficient size determining tool in the biosynthesis of cobalt nanocatalyst. Experimental behavior using potentiometric analysis confirms that the linearity in CoNCs formation and size coincides (5-38 nm)with the predicted values of the ANN model. Techno economic analysis proved that, green synthesis reduced 30-40% in raw material cost and 60% in energy consumption.
When people suspect a child or young person is experiencing, or at risk of, abuse or neglect, they have to decide how to respond. However, the under and over reporting of child welfare issues indicate that people may struggle to identify an appropriate response.

To develop scenarios (for future training and research purposes) that closely resemble the child welfare situations health/allied health practitioners encounter, and for which there is a reasonable level of child protection professional consensus as to what the appropriate response for each situation should be.

We developed 285 scenarios from 190 child protection reports made by health/allied health practitioners to two Australian government child welfare agencies, that covered a range of appropriate response pathways and abuse types. An appropriate response pathway for each scenario was identified by having 34 child protection professionals provide their opinion and rationales.

Child protection professionals displayed moderate (e.g., krippendorf's alpha = 0.58, 95 % CI 0.52 to 0.62) interrater agreement as to the appropriate response pathway for the scenarios. For 127 of the 285 scenarios (44.56 %), there was strong consensus (K = 0.73, 95 % CI 0.66 to 0.78).

Professional consensus was higher than anticipated from previous research, although still low compared to generally acceptable levels of consensus. Our results suggest several promising avenues to increase professional consensus, such as improving the quality of information that people typically report to child welfare agencies.

Previous studies have found a high co-occurrence between Intimate Partner Violence exposure (IPVe) and other forms of victimization, such as physical and sexual abuse, yet little is known about this issue from community samples in Latin America or -in particular- Chile.

To examine the prevalence, sociodemographic correlates and co-occurrence of IPVe with other youth victimizations in Chile.

A secondary data analysis of the First Poly-victimization Survey in Children and Adolescents in Chile was conducted, which had 19,684 responses from 7
to 11
grade students attending publicly-funded, subsidized and independent schools in urban areas across the country.

The Juvenile Victimization Questionnaire was applied, and sociodemographic information was collected. Multiple logistic regression models were used.

The prevalence of lifetime IPVe was 13.0 % (95 % CI [12.4-13.6]), and 3.6 % (95 % CI [3.4-4.0]) for past-year IPVe. The factors that were positively associated with lifetime IPVe were female, over 14 years old, indigenous ethnicity, with a disability, mother with immigrant status, living with only one parent, and attending publicly-funded and subsidized schools. Most of these associations were maintained for past-year IPVe. All victimizations studied were positively associated with lifetime and past-year IPVe. Poly-victimization, maltreatment and witnessing sibling abuse showed the strongest associations (adjusted OR > 4.0). Co-occurrence was particularly high among IPVe youth, especially for community violence (86.2 %) and any maltreatment (81.5 %) in lifetime reports.

An integrated approach to assessing IPVe and other forms of victimizations would enrich research and clinical practice, especially early detection of IPVe occurrences.

IBK is an extremely contagious ocular disease of cattle. We report here the structure of the oligosaccharide derived from the lipooligosaccharide from M. bovoculi type strain 237 (also known as ATCC BAA-1259T). GLC-MS and correlation NMR analysis of the oligosaccharide revealed 5 sugar residues, with a notable central branched 3,4,6-α-D-Glcp. An additional α-D-Manp was present ~30% on the sub-terminal α-D-Manp of the 4-linked branch. This oligosaccharide structure was consistent with other members of the Moraxellaceae where no heptose was present and 5-linked Kdo was directly attached to the central 3,4,6-α-D-Glcp.Hesperetin (HSP) is a natural flavonoid that offers useful curative effects for cardiovascular diseases, but its effect on myocardial ischemia and its precise mechanism remains unclear. The aim of this study is to explore the potential cardioprotective mechanism of HSP on myocardial ischemia caused by isoproterenol (ISO). Adult male Kunming mice were randomly divided into five groups control, ISO, low-dose HSP (L-HSP, 25 mg/kg/d), high-dose HSP (H-HSP, 50 mg/kg/d), and verapamil (VER) group. Treatment groups of mice received HSP or VER for seven days, and the groups other than the control group were injected with ISO (100 mg/kg/d) subcutaneously for two consecutive days to establish a model of myocardial ischemia. Electrocardiogram and heart-histology changes were used to assess changes in myocardial architecture. The activities and the content of oxidative stress markers and inflammatory cytokines were determined and assayed using kits respectively. The expressions of proteins associated with apoptosis and the Sirt1/Nrf2 pathway were evaluated by Western blotting. selleck kinase inhibitor The results demonstrate that VER, L-HSP and H-HSP significantly reduced the J-point displacement, heart rate, cardiac pathomorphological changes, and the levels of creatine kinase, lactated dehydrogenase, malonaldehyde, interleukin-6, and tumor necrosis factor-α in serum while promoting the activation of superoxide dismutase, catalase, glutathione in serum in the ISO-treated animals. Furthermore, L-HSP and H-HSP also reversed the ISO-induced apoptosis and the changes in the Sirt1/Nrf2 signaling pathway, as evident from the levels of proteins Bax, Bcl-2, caspase-3, Sirt1, Nrf2, NQO-1, and HO-1. In conclusion, HSP plays a protective role in ISO-induced myocardial ischemia by modulating oxidative stress, inflammation, and apoptosis via Sirt1/Nrf2 pathway activation.
In recent years, magnetic nanoparticles (NMP) as novel materials have been widely used for biomedical, diagnostic and therapeutic purposes like microbial infection therapy. The purpose of this study is to synthesize PO coated iron oxide magnetic nanoparticles (Fe3O4@PO NPs) and their anti-leishmanial effects in vitro and in vivo against cutaneous leishmaniasis.

Fe3O4 magnetic nanoparticles were synthesized by the coprecipitation of Fe2+ and Fe3+ions and used as a nanocarrier for the production of Fe3O4@PO NPs. The in vitro antileishmanial effects of PO-coated Fe3O4 NPs and Fe3O4 NPs (10-200µg/mL) was determined against the intracellular amastigotes of Leishmania major (MRHO/IR/75/ER) and, then, examined on cutaneous leishmaniasis induced in male BALB/c mice by L. major. The rate of infectivity, production of nitric oxide (NO), and cytotoxic activates of Fe3O4 NPs and Fe3O4@PO NPs on J774-A1 macrophage cells were determined.

The size scattering of the Fe3O4 NPs and Fe3O4@PO NPs were in the range among 1-icity. The results also indicated that, although the possible anti-leishmanial mechanisms of Fe3O4@PO NPs have not been clearly understood, however, the triggering of NO may be considered as one of the possible anti-leishmanial mechanisms of these nanoparticles. However, additional studies, in particular in clinical contexts, are mandatory.
The results of this survey indicated the high potency of Fe3O4@PO NPs to inhibit the growth of amastigote forms of L. major as well as recovery and improvement CL induced by L. major in BALB/c mice without significant cytotoxicity. The results also indicated that, although the possible anti-leishmanial mechanisms of Fe3O4@PO NPs have not been clearly understood, however, the triggering of NO may be considered as one of the possible anti-leishmanial mechanisms of these nanoparticles. However, additional studies, in particular in clinical contexts, are mandatory.
Diabetes mellitus is related to cognitive impairments and molecular abnormalities of the hippocampus. A growing body of evidence suggests that Urtica dioica (Ud) and exercise training (ET) have potential therapeutic effects on diabetes and its related complications. Therefore, we hypothesized that the combined effect of exercise training (ET) and Ud might play an important role in insulin signaling pathway, oxidative stress, neuroinflammation, and cognitive impairment in diabetic rats.

Forty animals were divided into five groups (N=8) healthy-sedentary (H-sed), diabetes-sedentary (D-sed), diabetes-exercise training (D-ET), diabetes-Urtica dioica (D-Ud), diabetes-exercise training-Urtica dioica (D-ET-Ud). Streptozotocin (STZ) (Single dosage; 45mg/kg, i.p.) was used to induce diabetes. Then, ET (moderate intensity/5day/week) and Ud extract (50mg/kg, oral/daily) were administered for six weeks. We also investigated the effects of ET and Ud on cognitive performance (assessed through Morris Water Maze tests), antioxidant capacity, and lipid peroxidation markers in hippocampus.
