Objective:To determine the potential effect of environment variables on cutaneous leishmaniasis occurrence using time-series models and compare the predictive ability of seasonal autoregressive integrated moving average(SARIMA)models and Markov switching model(MSM).Methods:This descriptive study employed yearly and monthly data of 49364 parasitologically-confirmed cases of cutaneous leishmaniasis in Isfahan province,located in the center of Iran from January 2000 to December *** data were provided by the leishmaniasis national surveillance system,the meteorological organization of Isfahan province,and Iranian Space Agency for vegetation *** SARIMA and MSM models were implemented to examine the environmental factors of cutaneous leishmaniasis ***:The minimum relative humidity,maximum relative humidity,minimum wind speed,and maximum wind speed were significantly associated with cutaneous leishmaniasis epidemics in different lags(P<0.05).Comparing SARIMA and MSM,Akaikes information criterion(AIC),and mean absolute percentage error(MAPE)in MSM were much smaller than SARIMA models(MSM:AIC=0.95,MAPE=3.5%;SARIMA:AIC=158.93,MAPE:11.45%).Conclusions:SARIMA and MSM can be a useful tool for predicting cutaneous leishmaniasis in Isfahan *** cutaneous leishmaniasis falls into one of two states of epidemic and non-epidemic,the use of MSM(dynamic)is recommended,which can provide more information compared to models that use a single distribution for all observations(Box-Jenkins SARIMA model).

Ammonium is an important nutrient in primary production; however, high ammonium loads can cause eutrophication of natural waterways, contributing to undesirable changes in water quality and ecosystem structure. While ammonium pollution comes from diffuse agricultural sources, making control difficult, industrial or municipal point sources such as wastewater treatment plants also contribute significantly to overall ammonium *** latter sources can be targeted more readily to control ammonium release into water systems. To assist policy makers and researchers in understanding the diversity of treatment options and the best option for their circumstance, this paper produces a comprehensive review of existing treatment options for ammonium removal with a particular focus on those technologies which offer the highest rates of removal and cost-effectiveness. Ion exchange and adsorption material methods are simple to apply, cost-effective, environmentally friendly technologies which are quite efficient at removing ammonium from treated water. The review presents a list of adsorbents from the literature, their adsorption capacities and other parameters needed for ammonium removal. Further, the preparation of adsorbents with high ammonium removal capacities and new adsorbents is discussed in the context of their relative cost, removal efficiencies, and limitations. Efficient, cost-effective, and environmental friendly adsorbents for the removal of ammonium on a large scale for commercial or water treatment plants are provided. In addition, future perspectives on removing ammonium using adsorbents are presented.

Precursor messenger RNA(pre-mRNA)splicing is a fundamental step in eukaryotic gene expression that systematically removes non-coding regions(introns)and ligates coding regions(exons)into a continuous message(mature mRNA).This process is highly regulated and can be highly flexible through a process known as alternative splicing,which allows for several transcripts to arise from a single gene,thereby greatly increasing genetic plasticity and the diversity of *** splicing is particularly prevalent in neuronal cells,where the splicing patterns are continuously changing to maintain cellular homeostasis and promote neurogenesis,migration and synaptic *** continuous changes in splicing patterns and a high demand on many cis-and trans-splicing factors contribute to the susceptibility of neuronal tissues to splicing *** resultant neurodegenerative diseases are a large group of disorders defined by a gradual loss of neurons and a progressive impairment in neuronal *** of the most common neurodegenerative diseases involve some form of splicing defect(s),such as Alzheimer’s disease,Parkinson’s disease and spinal muscular *** growing understanding of RNA splicing has led to the explosion of research in the field of splice-switching antisense oligonucleotide *** we review our current understanding of the effects alternative splicing has on neuronal differentiation,neuronal migration,synaptic maturation and regulation,as well as the impact on neurodegenerative *** will also review the current landscape of splice-switching antisense oligonucleotides as a therapeutic strategy for a number of common neurodegenerative disorders.
