Title: Dissecting the Diverse Actions of Pro- and Mature Neurotrophins. VOLUME: 3 ISSUE: 1. Author(s):Barbara L. Hempstead. Affiliation:Department of Medicine,Weill Medical College of Cornell University, 1300 York Avenue, NewYork, NY 10021, USA.. Keywords:Neurotrophin, NGF, BDNF, proneurotrophin, sortilin, p75, Trk. Abstract: The neurotrophins mediate diverse actions in the developing peripheral and central nervous systems. They are initially synthesized as precursor forms, or proneurotrophins, that are cleaved to release C-terminal mature forms that bind to Trk receptor tyrosine kinases to enhance synaptic plasticity and neuronal survival. Recent studies suggest that proneurotrophins are not inactive precursors, but signaling proteins that can activate the p75 receptor to mediate diverse responses. Proneurotrophins can activate a heteromeric receptor complex of p75 and sortilin to initiate cell death, or bind to p75 in hippocampal neurons to enhance long term depression. Thus, neurotrophin ...

The FDA had warned that e-cig use poses acute health risks, that the dangers posed by their toxic chemicals . . . cannot seriously be questioned, and that they have caused a wide variety of potentially serious symptoms including racing pulse, dizziness, slurred speech, mouth ulcers, heartburn, coughing, diarrhea, and sore throat. (E-cigarettes - scientists want more safety studies before use..FDA had found that samples it tested contained detectable levels of known carcinogens and toxic chemicals to which users could be exposed. The FDA said the toxic chemicals included diethylene glycol, an ingredient used in antifreeze, [which] is toxic to humans; certain tobacco-specific nitrosamines which are human carcinogens; and that tobacco-specific impurities suspected of being harmful to humans -- anabasine, myosmine, and B-nicotyrine -- were detected in a majority of the samples tested. The FDA does not currently monitor or license e-cigs, and indeed considers them illegal ...

GW-405,833 (L-768,242) is a drug that acts as a potent and selective partial agonist for the cannabinoid receptor subtype CB2, with an EC50 of 0.65 nM and selectivity of around 1200x for CB2 over CB1 receptors.[1][2] Animal studies have shown it to possess antiinflammatory and anti-hyperalgesic effects at low doses, followed by ataxia and analgesic effects when the dose is increased.[3][4] Selective CB2 agonist drugs such as GW-405,833 are hoped to be particularly useful in the treatment of allodynia and neuropathic pain for which current treatment options are often inadequate.[5][6] ...

WP Number: 1708. Abstract: We study a setting where individuals prefer to coordinate with others but they differ on their preferred action. Our interest is understanding the role of linking in shaping behavior. So we consider the situation in which interactions are exogenous and a situation where individuals choose links that determine the interactions. Theory is permissive in both settings: conformism (on either of the actions) and diversity (with different groups choosing their preferred actions) are both sustainable in equilibrium. Our experiments reveal that, in an exogenous complete network, subjects choose to conform to the majoritys preferred action. By contrast, when linking is free and endogenous, subjects form dense networks (biased in favour of linking within same preferences type) but choose diverse actions. The convergence to diverse actions is faster under endogenous linking as compared to the convergence to conformity on the majoritys preferred action under the exogenous ...

Abstract: We present new observations of 26 symbiotic and symbiotic-like stars. The photoelectric UBV observations were made during the years 1982-92, the photographic in 1989-92 and visual in 1989-92. The most interesting results can be summarized as follows: EG And: There is an apparent increase in all three colours corresponding to the ascending branch of the secondary minimum. UV Aur: The long-term photoelectric photometry supports our earlier identification of the red giant component as the primary cause of light variations. BF Cyg: UBV data cover well the last active phase of the star with maximum around 1990 July. CH Cyg: The photoelectric data cover the sudden light brightening starting in Feb-Mar 1992 and decline in Sep 1992. CI Cyg: Long-term UBV observations are presented. AG Dra: UBV photometry cover almost all the interval since the last outburst. CQ Dra: The stars brightness has been decreasing monotonically during the present observational period.

In 2017, more than 5 million house structures were sprayed through the U.S. Presidents Malaria Initiative, protecting more than 21 million people in sub-Saharan Africa. New IRS formulations, SumiShield™ 50WG and Fludora Fusion™ WP-SB, became World Health Organization (WHO) prequalified vector control products in 2017 and 2018, respectively. Both formulations contain the neonicotinoid active ingredient, clothianidin. The target site of neonicotinoids represents a novel mode of action for vector control, meaning that cross-resistance through existing mechanisms is less likely. In preparation for rollout of clothianidin formulations as part of national IRS rotation strategies, baseline susceptibility testing was conducted in 16 countries in sub-Saharan Africa. While work coordinated by the WHO is ongoing to develop a suitable bottle bioassay procedure, there was no published guidance regarding clothianidin susceptibility procedures or diagnostic concentrations.

This means they are absorbed into every part of a plant - from the roots and stem, to leaves and flowers. Neonicotinoids are especially effective against sap-feeding insects like aphids. Although these low level exposures do not normally kill bees directly, they may impact some bees ability to foraging for nectar, learn and remember where flowers are located, and possibly impair their ability to find their way home to the nest or hive. Neonicotinoids are systemic chemicals, meaning that they are absorbed … Clothianidin and thiamethoxam were found responsible, via the talc used to allow treated seed to flow smoothly through the air-assisted planter equipment. For many products such as corn, its nearly impossible for farmers to buy seeds that are not treated. Since then a further six compounds have been put on the global market. Neonicotinoids, neonics for short, are a class of synthetic pesticides used to prevent insect damage on a variety of crops. They are a relatively new type of ...

Experimental evidence demonstrates that the toxicity of neonicotinoids increases with exposure time as much as with the dose, and therefore it has been described as time-cumulative toxicity. This pattern of toxicity, also found among carcinogenic compounds and other toxicants, has been ignored in ecotoxicology and risk assessments for a long time. The implications of the time-cumulative toxicity of neonicotinoids on non-target organisms of aquatic and terrestrial environments are far reaching. Firstly, neonicotinoids are incompatible with integrated pest management (IPM) approaches and secondly regulatory assessments for this class of compounds cannot be based solely on exposure doses but need also to take into consideration the time factor..

We are interested in understanding how kainate receptors, a family of ionotropic glutamate receptors in the mammalian CNS, operate at a molecular and biophysical level. Kainate receptors are modulatory proteins that help to balance excitatory and inhibitory tone through diverse actions at pre- and postsynaptic sites. They also have been shown to be promising drug targets in several pathologies (particularly epilepsy and chronic pain). A current project focuses on how an associated family of auxiliary proteins, known as Neto-1 and Neto-2, shape kainate receptor function. We would like to identify which domains in both the receptor subunits and auxiliary proteins are key for allosteric modulation by Neto proteins ...

p,Neonicotinoids are a widely used class of insecticides that are commonly applied as seed coatings for agricultural crops. Such neonicotinoid use may pose a risk to non-targetinsects, including pollinators and natural enemies of crop pests, and ecosystems. This study assessed neonicotinoid residues in groundwater, surface runoff water, soil, and native plants adjacent to corn and soybean crop fields with a history of being planted with neonicotinoid-treated seeds from 2008 to 2013. Data from six sites with the same crop management history, three with and three without in-field prairie strips, were collected in 2015-2016, 2-3 years after neonicotinoid (clothianidin and imidacloprid) seed treatments were last used. Three of the six neonicotinoids analyzed were detected in at least one environmental matrix: the two applied as seed coatings on the fields (clothianidin and imidacloprid) and another widely used neonicotinoid (thiamethoxam). Sites with prairie strips generally had lower concentrations ...

Neonicotinoid insecticides are widely used in both urban and agricultural settings around the world. Historically, neonicotinoid insecticides have been viewed as ideal replacements for more toxic compounds, like organophosphates, due in part to their perceived limited potential to affect the environment and human health. This critical review investigates the environmental fate and toxicity of neonicotinoids and their metabolites and the potential risks associated with exposure. Neonicotinoids are found to be ubiquitous in the environment, drinking water, and food, with low-level exposure commonly documented below acceptable daily intake standards. Available toxicological data from animal studies indicate possible genotoxicity, cytotoxicity, impaired immune function, and reduced growth and reproductive success at low concentrations, while limited data from ecological or cross-sectional epidemiological studies have identified acute and chronic health effects ranging from acute respiratory, cardiovascular,

Since their discovery in the late 1980s, neonicotinoid pesticides have become the most widely used class of insecticides worldwide, with large-scale applications ranging from plant protection (crops, vegetables, fruits), veterinary products, and biocides to invertebrate pest control in fish farming. In this review, we address the phenyl-pyrazole fipronil together with neonicotinoids because of similarities in their toxicity, physicochemical profiles, and presence in the environment. Neonicotinoids and fipronil currently account for approximately one third of the world insecticide market; the annual world production of the archetype neonicotinoid, imidacloprid, was estimated to be ca. 20,000tonnes active substance in 2010. There were several reasons for the initial success of neonicotinoids and fipronil: (1) there was no known pesticide resistance in target pests, mainly because of their recent development, (2) their physicochemical properties included many advantages over previous generations of ...

Final registration decisions on the chemicals are not due until the winter of 2018-19, so farmers and companies are unlikely to see any changes to their use of the chemicals before then.. Neonicotinoids are used to control insects in corn, soybeans, cotton, canola and many other crops. They have become a staple in the crop production industry, with millions of pounds of neonicotinoid insecticides applied to corn, soybean and cotton seed annually. However, the chemicals have been implicated in the decline in pollinator health, and EPAs registration review of the chemicals has been closely watched by industry, farmers and environmentalists worldwide as a result.. In this latest development, EPA released its preliminary pollinator-only risk assessments for the neonicotinoid insecticides clothianidin (Poncho), thiamethoxam (Cruiser), and dinotefuran, a preliminary aquatic risk assessment for imidacloprid (Gaucho), and an update to its preliminary pollinator-only risk assessment for imidacloprid ...

Why are the Bees Dying Off? Reason #1: Neonicotinoid Pesticides. It has become well known especially in Russia and Europe that neonicotinoid pesticides are linked to bees dying off. Consequently, Europe restricted the use of 3 neonicotinoids for two years starting December 1st, 2013. Neonicotinoids are a relatively new class of insecticides that have a chemical structure very similar to nicotine (hence their name), and work by severely disrupting the central nervous system of insects, leading to paralysis and death. Common neonicotinoids are imidacloprid, acetamiprid and clothianidin, with Bayers imidacloprid the most widely used insecticide in the world.. Numerous studies have linked neonicotinoids and CCD, such as:. - this 2012 Xerxes study which found that few field studies have been properly designed or conducted over a long enough period of time to assess the full risks to bees. Nevertheless, the overall evidence points to the fact that neonicotinoids are harming bees;. - this 2014 study ...

Genotoxicity of the Neonicotinoid Insecticide Poncho (Clothianidin) on CD1 Mice Based on Alkaline Comet and Micronucleus Assays. By María Elena Calderón-Segura, José Arturo Marcial Rojas, María de Guadalupe Mézquita Brito, Manuel TecCab, María del Carmen Calderón-Ezquerro and Sandra Gómez-Arroyo. Poncho is a commercial formulation of neonicotinoid insecticides and a new agrochemical in Mexico, and it has the active ingredient clothianidin. The genotoxic effects of this commercial formulation of clothianidin on CD1 male mice were analyzed using micronucleus and comet alkaline assays. Three concentrations of clothianidin (20, 40, and 80 mg/kg/body weight) as well as negative (deionized water) and positive controls (cyclophosphamide 40 mg/g/body weight) were intraperitoneally injected into groups of mice every 3 days for 21 days. Peripheral blood samples were drawn from the caudal vein and divided to carry out the comet alkaline and micronuclei assays. DNA damage was evaluated using three ...

Neonicotinoids are considered safe because of their low affinities to mammalian nicotinic acetylcholine receptors (nAChRs) relative to insect nAChRs. However, because of importance of nAChRs in mammalian brain development, there remains a need to establish the safety of chronic neonicotinoid exposures with regards to childrens health. Here we examined the effects of longterm (14 days) and low dose (1 μM) exposure of neuron-enriched cultures from neonatal rat cerebellum to nicotine and two neonicotinoids: acetamiprid and imidacloprid. Immunocytochemistry revealed no differences in the number or morphology of immature neurons or glial cells in any group versus untreated control cultures. However, a slight disturbance in Purkinje cell dendritic arborization was observed in the exposed cultures. Next we performed transcriptome analysis on total RNAs using microarrays, and identified significant differential expression (p < 0.05, q < 0.05, ≥1.5 fold) between control cultures versus nicotine-,

While the EU acted in accordance with scientific research from the European Food Safety Authority, it will completely ban three substances (imidacloprid, clothianidin, and thiamethoxam) known as neonicotinoids everywhere except greenhouses.. The way neonicotinoids work is by integration throughout a plants structure, NPR reported. Instead of staying on the surface of the plant - such as its leaves - the chemicals are sent to the flowers, pollen and nectar, which attacks bees nervous systems when encountered killing the crucial pollinators and keeping others from laying eggs.. Bee health remains of paramount importance for me since it concerns biodiversity, food production and the environment, Vytenis Andriukaitis, the EUs Commissioner for Health and Food Safety, said.. Bayer CropScience, Europes biggest seller of neonicotinoids, reacted to the ban by saying it will not improve the lot of bees or other pollinators and instead, it is a sad day for farmers and a bad deal for ...

Purpose: Survivin is an inhibitor of apoptosis protein (IAP) that is highly expressed in many cancers and represents an attractive molecule for targeted cancer therapy. Although primarily regarded as an intracellular protein with diverse actions, survivin has also been identified in association with circulating tumor exosomes.. Experimental Design: We have reported that active, specific vaccination with a long peptide survivin immunogen leads to the development of survivin-specific CD8-mediated tumor cell lysis and prolongation of survival in tumor-bearing mice. In addition to cellular antitumor responses, circulating anti-survivin antibodies are detected in the serum of mice and human glioblastoma patients following vaccination with the survivin immunogen.. Results: Here we demonstrate that survivin is present on the outer cell membrane of a wide variety of cancer cell types, including both murine and human glioma cells. In addition, antibodies to survivin that are derived from the immunogen ...

Nicotine is of importance as the addictive chemical in tobacco, pharmacotherapy for smoking cessation, a potential medication for several diseases, and a useful probe drug for phenotyping cytochrome P450 2A6 (CYP2A6). We review current knowledge about the metabolism and disposition kinetics of nicotine, some other naturally occurring tobacco alkaloids, and nicotine analogs that are under development as potential therapeutic agents. The focus is on studies in humans, but animal data are mentioned when relevant to the interpretation of human data. The pathways of nicotine metabolism are described in detail. Absorption, distribution, metabolism, and excretion of nicotine and related compounds are reviewed. Enzymes involved in nicotine metabolism including cytochrome P450 enzymes, aldehyde oxidase, flavin-containing monooxygenase 3, amine N-methyltransferase, and UDP-glucuronosyltransferases are represented, as well as factors affecting metabolism, such as genetic variations in metabolic enzymes, ...
