Recent technical advances in electrophysiological measurements, organelle-targeted fluorescence imaging, and organelle proteomics have pushed the research of ion transport a step forward in the case of the plant bioenergetic organelles, chloroplasts and mitochondria, leading to the molecular identification and functional characterization of several ion transport systems in recent years. Here we focus on channels that mediate relatively high-rate ion and water flux and summarize the current knowledge in this field, focusing on targeting mechanisms, proteomics, electrophysiology, and physiological function. In addition, since chloroplasts evolved from a cyanobacterial ancestor, we give an overview of the information available about cyanobacterial ion channels and discuss the evolutionary origin of chloroplast channels. The recent molecular identification of some of these ion channels allowed their physiological functions to be studied using genetically modified Arabidopsis plants and cyanobacteria. The view is emerging that alteration of chloroplast and mitochondrial ion homeostasis leads to organelle dysfunction, which in turn significantly affects the energy metabolism of the whole organism. Clear-cut identification of genes encoding for chan- nels in these organelles, however, remains a major challenge in this rapidly developing field. Multiple stra- tegies including bioinformatics, cell biology, electrophysiology, use of organelle-targeted ion-sensitive probes, genetics, and identification of signals eliciting specific ion fluxes across organelle membranes should provide a better understanding of the physiological role of organellar channels and their contribution to signaling pathways in plants in the future.

CONCLUSION:The double-pass system provides accurate and reliable estimates of the SE that can be used for clinical *** technique can determine the correct focus position to assess the ocular optical ***,it has a relatively small measuring range in comparison with autorefractors(-8.00 to +5.00D),and requires prior information on the refractive state of the patient.

Wastewater treatment center（WTC） workers may be vulnerable to diseases caused by viruses, such as the common cold, influenza and gastro-intestinal infections. Although there is a substantial body of literature characterizing the microbial community found in wastewater, only a few studies have characterized the viral component of WTC aerosols,despite the fact that most diseases affecting WTC workers are of viral origin and that some of these viruses are transmitted through the air. In this study, we evaluated in four WTCs the presence of 11 viral pathogens of particular concern in this milieu and used a metagenomic approach to characterize the total viral community in the air of one of those WTCs. The presence of viruses in aerosols in different locations of individual WTCs was evaluated and the results obtained with four commonly used air samplers were *** detected four of the eleven viruses tested, including human adenovirus（h Ad V）,rotavirus, hepatitis A virus（HAV） and Herpes Simplex virus type 1（HSV1）. The results of the metagenomic assay uncovered very few viral RNA sequences in WTC aerosols, however sequences from human DNA viruses were in much greater relative abundance.

INTRODUCTION The presentation of cardiogenic shock （CS） is usually straightforward, and includes hypotension, absence of hypovolemia, and clinical signs of poor tissue perfusion such as oliguria, cyanosis, cool extremities and altered mentation. The most common etiology of CS is acute myocardial infarction, Here, we report a case of a 42-year-old male who presented with right flank pain, nausea and vomiting initially thought to be nephrolithiasis, which he had a history of but was ultimately diagnosed with CS due to a type II myocardial infarction. This case illustrates the importance of having a broad differential diagnosis especially when a patient＇s vital signs take a drastic turn since this patient initially resembled someone with nephrolithiasis.
