New therapeutic strategies against leishmaniasis are desirable, since the treatment against disease presents problems, such as the toxicity, high cost and/or parasite resistance. As consequence, new antileishmanial compounds are necessary to be identified, as presenting high activity against Leishmania, but low toxicity in mammalian hosts. In the present study, a Leishmania proteome mining strategy was developed, in order to select new drug targets with low homology to human proteins, but that are considered relevant for the parasite' survival.

Ischemia-reperfusion injuries produce reactive oxygen species that promote the peroxide lipid oxidation process resulting in the production of an endogenic lipid peroxide, 4-hydroxy-trans-2-nonenal (4-HNE), a highly cytotoxic aldehyde that induces cell death. We synthesized a novel 4-HNE scavenger - a carnosine-hydrazide derivative, l-carnosine hydrazide (CNN) - and examined its neuroprotective effect in a model of transient ischemia. PC-12 cells were pre-incubated with various doses (0-50 mmol/L) of CNN for 30 min, followed by incubation with 4-HNE (250 μM). Read More

Because the application of Bisphenol A (BPA) was restricted, many substitutes, such as Bisphenol F (BPF) and Bisphenol S (BPS), were developed as BPA substitutes. Therefore, environmental impacts of BPA and its substitutes on aquatic organisms should be concerned, especially their combined toxicity. In this study, the impacts of BPA, BPF, BPS and their mixture on the feeding behavior, reproduction and physiological function of daphnids were synthetically evaluated, involving the duration and mode of exposure.

This paper aims to evaluate the effects of a product containing colloidal silver in the aquatic environment, using duckweed Lemna gibba as a model plant. Therefore, growth parameters, photosynthetic pigments content and protein content as physiological indices were evaluated. Changes in the content of non-enzymatic antioxidants and activity of several antioxidant enzymes, alongside with the accumulation of hydrogen peroxide and lipid peroxidation end-products were assessed to explore the potential of colloidal silver to induce oxidative stress.

In this work, we designed polysaccharide-metal complex of dopamine-modified pectin linking ruthenium compound, which exhibited a certain inhibition specificity to human renal cell adenocarcinoma cell line 786-O. The chemical structure and physical properties of the polysaccharide-metal complex were well characterized by multiple analysis methods. The multi-spectral results revealed that pectin-dopamine have been successfully coordinated by ruthenium complex to form nano-conjugates, which self-assembled into relatively regular nanospheres of approximately 200 nm.

Body composition has gained increasing attention in oncology in recent years due to fact that sarcopenia has been revealed to be a strong prognostic indicator for survival across multiple stages and cancer types and a predictive factor for toxicity and surgery complications. Accumulating evidence over the last decade has unraveled the "pharmacology" of sarcopenia. Lean body mass may be more relevant to define drug dosing than the "classical" body surface area or flat-fixed dosing in patients with cancer. Read More

In this study, eighteen novel steroidal-furoxan derivatives with 3-glycosyl or 3-methoxy moiety (12a-c, 13a-c, 17a-c, 26a-c, 27a-c and 28a-c) were synthesized and their anti-proliferative activity was evaluated against eight drug-sensitive and three drug-resistant cancer cell lines HeLa, A2780, LNCaP, PC-3, MDA-MB-231, MCF-7, SW480, A549, MCF-7/ADR, A2780/CDDP and A2780/T. Most of them displayed significant anti-cancer potency in vitro with IC values at the nanomole level. Among them, 3-methoxy steroidal-furoxan hybrids expressed much better activity than that of 3-glycosyl substitute ones, while estrane and 5α-H-androstane scaffold were slightly more favorable to the improvement of anti-proliferative activity.

Abrin, an extremely cytotoxic Type-II ribosome inactivating protein (RIP), is a potential bio-warfare agent. Abrin A-chain (ABA) depurinates an adenosine of sarcin-ricin loop (SRL) from eukaryotic 28S rRNA thereby arresting protein synthesis and leading to cell death. Monoclonal antibody (mAb) D6F10 is the only known antibody that neutralizes ABA's activity in cell-free systems as well as abrin's toxicity in vitro and in vivo. Read More

Mutations of the SPAST gene, which encodes the microtubule-severing protein spastin, are the most common cause of Hereditary Spastic Paraplegia. Haploinsufficiency is the prevalent opinion as to the mechanism of the disease, but gain-of-function toxicity of the mutant proteins is another possibility. Here, we report a new transgenic mouse (termed SPASTC448Y mouse) that is not haploinsufficient but expresses human spastin bearing the HSP pathogenic C448Y mutation. Read More

Stroke is the result of blockage or rupture of blood vessels in the brain and is the leading cause of death and disability in the world. Currently only a very limited number of therapeutic approaches are available for treatment of stroke patients, and the vast majority of neuroprotective agents that tested positively in pre-clinical studies failed in clinical trials. In recent years, the clinical value of the use of exosomes for stroke treatment has received widespread attention due their unique characteristics such as low immunogenicity, low toxicity and biodegradability, ability to cross the blood-brain barrier (BBB), and their important role in communication between cells.

The European Commission intends to protect vertebrate wildlife populations by regulating Plant Protection Product (PPP) active substances that have endocrine disrupting properties with a hazard-based approach. In this paper we consider how the Commission's hazard-based Regulation and accompanying Guidance can be operationalised to ensure that a technically robust process is used to distinguish between substances with adverse population level effects and those for which it can be demonstrated that adverse effects observed (typically in the laboratory) do not translate into adverse effects at the population level. Our approach is to use population models within the adverse outcome pathway framework to link the non-linear relationship between adverse effects at the individual and population levels in the following way: (1) Use Specific Protection Goals for focal wildlife populations within an ecosystem services framework; (2) Model the effects of changes in population-related inputs on focal species populations using individual-based population models to determine thresholds between negligible and non-negligible (i.
