TL;DR: Data indicate that enzymatic activity is relevant for some pharmacological effects induced by crotoxin B (mainly lethal, myotoxic and anticoagulant activities), and also evidence that this subunit of crot toxin displays regions different from the active catalytic site which are involved in some of the toxic and pharmacological results induced by this phospholipase A(2).

TL;DR: In this article, the application, mechanisms and limitations of simple alkylating agents that can be used for the conversion of carboxylic acids to esters, phenols to aryl ethers, enols to enol ethers and thiols to thioethers are discussed.
Abstract: This review covers the application, mechanisms and limitations of simple alkylating agents that can be used for the conversion of carboxylic acids to esters, phenols to aryl ethers, enols to enol ethers and thiols to thioethers. Specific recent examples are provided to show the selectivity (regio or chemo) in these transformations. It is important to have access to these methods when considering alternatives to classical alkylating techniques.

TL;DR: The results of a genomewide association study of severe bipolar disorder (BP-I), using patients from the isolated population of the central valley of Costa Rica, report the most striking results were in proximal 8p, a region that has previously shown linkage to schizophrenia.
Abstract: Genomewide association studies may offer the best promise for genetic mapping of complex traits. Such studies in outbred populations require very densely spaced single-nucleotide polymorphisms. In recently founded population isolates, however, extensive linkage disequilibrium (LD) may make these studies feasible with currently available sets of short tandem repeat markers, spaced at intervals as large as a few centimorgans. We report the results of a genomewide association study of severe bipolar disorder (BP-I), using patients from the isolated population of the central valley of Costa Rica. We observed LD with BP-I on several chromosomes; the most striking results were in proximal 8p, a region that has previously shown linkage to schizophrenia. This region could be important for severe psychiatric disorders, rather than for a specific phenotype.

TL;DR: In this paper, the authors review the past decade of research on agricultural and ecological climate change impact models for Central America and provide insights into the expected impacts of climate change and suggest policy actions that can help minimize these impacts.
Abstract: Climate change will have serious repercussions for agriculture, ecosystems, and farmer livelihoods in Central America. Smallholder farmers are particularly vulnerable due to their reliance on agriculture and ecosystem services for their livelihoods. There is an urgent need to develop national and local adaptation responses to reduce these impacts, yet evidence from historical climate change is fragmentary. Modeling efforts help bridge this gap. Here, we review the past decade of research on agricultural and ecological climate change impact models for Central America. The results of this review provide insights into the expected impacts of climate change and suggest policy actions that can help minimize these impacts. Modeling indicates future climate-driven changes, often declines, in suitability for Central American crops. Declines in suitability for coffee, a central crop in the regional economy, are noteworthy. Ecosystem models suggest that climate-driven changes are likely at low- and high-elevation montane forest transitions. Modeling of vulnerability suggests that smallholders in many parts of the region have one or more vulnerability factors that put them at risk. Initial adaptation policies can be guided by these existing modeling results. At the same time, improved modeling is being developed that will allow policy action specifically targeted to vulnerable groups, crops, and locations. We suggest that more robust modeling of ecological responses to climate change, improved representation of the region in climate models, and simulation of climate influences on crop yields and diseases (especially coffee leaf rust) are key priorities for future research.
