BACKGROUND: Little is known about the characteristics and real world life circumstances of ARDS (acute respiratory distress syndrome) patient populations. This knowledge is essential for transferring evidence-based therapy into routine healthcare. The aim of this study was to report socio-demographic and clinical characteristics in an unselected population of ARDS patients and to compare these results to findings from other large ARDS cohorts. METHODS: A German based cross-sectional observational study was carried out...

During the last decades, contrasted trends in forest fires among countries around the Mediterranean basin have been observed. In the northern/western countries, Land Use-Land Cover (LULC) changes led to more hazardous landscapes, with consequent increases in fires. This contrasted with fire trends in southern/eastern countries. The recent incidence of large fires in some of the latter prompted the question of whether they are now following the path of their neighbors decades earlier. In this study, we investigated recent LULC changes in southwestern Turkey, focusing on those that could affect fire, and the factors driving them...

Recombinations occur nonuniformly across the maize genome. To dissect the genetic mechanisms underlying the nonuniformity of recombination, we performed quantitative trait locus (QTL) mapping using recombinant inbred line populations. Genome-wide QTL scan identified hundreds of QTLs with both cis-prone and trans- effects for recombination number variation. To provide detailed insights into cis- factors associated with recombination variation, we examined the genomic features around recombination hot regions, including density of genes, DNA transposons, retrotransposons, and some specific motifs...

The germinal center (GC) is the site where activated B cells undergo rapid expansions, somatic hypermutation, and affinity maturation. Affinity maturation is a process of Ag-driven selection. The amount of Ag acquired and displayed by GC B cells determines whether it can be positively selected, and therefore Ag acquisition has to be tightly regulated to ensure the efficient affinity maturation. Cell expansion provides sufficient quantity of GC B cells and Abs, whereas affinity maturation improves the quality of Abs...

Hand, foot, and mouth disease (HFMD) is a common pediatric disease caused by enterovirus infection. It typically presents as a fever along with flat, discolored spots and bumps on the hands, feet, and mouth. Compared with other viruses, enterovirus 71 (EV71)-induced HFMD is more prone to cause severe complications in children, such as brainstem encephalitis, cardiopulmonary disorders, and even death. More in-depth studies are still necessary to understand the characteristics of EV71-induced HFMD, although some related research has been reported so far...

PURPOSE: To assess the presence of outer and inner retinal folds (RFs) and drop-out of the ellipsoid zone (EZ) occurring after surgical repair of macula-off rhegmatogenous retinal detachment (RRD) with different postoperative posture and preoperative use of adjuvant perfluorocarbon liquid (PFCO). METHODS: In this prospective study, 56 eyes of 56 consecutive patients affected by RRD were subjected to 23- or 25-gauge pars plana vitrectomy (PPV). The patients were randomized in four groups (14 prone 5 hr without PFCO, 14 supine 5 hr without PFCO, 14 prone 5 hr with PFCO and 14 supine 5 hr with PFCO) and followed up with spectral domain optical coherence tomography (SD-OCT)...

The microRNA (miRNA) can regulate the transcripts that are involved in eukaryotic cell proliferation, differentiation, and metabolism. Especially for plants, our understanding of miRNA targets, is still limited. Early attempts of prediction on sequence alignments have been plagued by enormous false positives. It is helpful to improve target prediction specificity by incorporating the other data sources such as the dependency between miRNA and transcript expression or even cleaved transcripts by miRNA regulations, which are referred to as trans-omics data...

Formaldehyde (HCHO) is the most important carcinogen in outdoor air among the 187 hazardous air pollutants (HAPs) identified by the US Environmental Protection Agency (EPA), not including ozone and particulate matter. However, surface observations of HCHO are sparse and the EPA monitoring network could be prone to positive interferences. Here we use 2005-2016 summertime HCHO column data from the OMI satellite instrument, validated with high-quality aircraft data and oversampled on a 5 × 5 km(2) grid, to map surface air HCHO concentrations across the contiguous US...

This study investigated the degradation kinetics and halonitromethanes formation potential (HNMsFP) of two nitro-based pharmaceuticals (i.e., ranitidine (RNTD) and nizatidine (NZTD)) during ultraviolet (UV) photolysis. It was found that the degradation kinetics of RNTD and NZTD exhibited pH-dependent trends, in accordance with their deprotonation equilibria. The neutral species of RNTD and NZTD were more photo-reactive than their corresponding deprotonated species, with their specific fluence-based first-order rate constants varying in the range of 5...

Addition of hydroxyl radicals to the C8 position of 2'-deoxyguanosine generates an 8-hydroxyguanyl radical that can be converted into either 8-oxo-7,8-dihydro-2'-deoxyguanosine or N-(2-deoxy-d-pentofuranosyl)-N-(2,6-diamino-4-hydroxy-5-formamidopyrimidine) (Fapy-dG). The Fapy-dG adduct can adopt different conformations and in particular, can exist in an unnatural α anomeric configuration in addition to canonical β configuration. Previous studies reported that in 5'-TGN-3' sequences, Fapy-dG predominantly induced G → T transversions in both mammalian cells and Escherichia coli, suggesting that mutations could be formed either via insertion of a dA opposite the 5' dT due to primer/template misalignment or as result of direct miscoding...

INTRODUCTION: The thoracolumbar fascia has been well studied and is known to have crisscrossing fibers. Based on surgical experience, we have hypothesized that the decussating fibers of this fascia may indicate a specific vertebral level. Therefore, the following anatomical study was performed. METHODS: Twenty adult fresh frozen cadavers aged 72-84 years old at death were placed in the prone position and the skin of the lumbar and upper sacrum was removed. Careful attention was given to the thoracolumbar fascia and any fibers of it that grossly crossed the midline to inderdigitate with its contralateral counterpart...

Postoperative visual loss is a rare and devastating complication. The estimated incidence is 0.01-1% after non ocular surgery. It has been reported after spine, cardiac and head and neck surgeries. We report a patient who was operated for cervical laminectomy in prone position and complained of loss of vision in one eye postoperatively. He was thoroughly investigated after visual loss. The case was diagnosed as central retinal artery occlusion (CRAO) of the left eye. Here we consider the potential etiological factors causing this unilateral loss of vision and try to suggest strategies to reduce the incidence of the complication in spinal surgery...

BACKGROUND: The treatment of people with acute abdominal pain differs if they have acute pancreatitis. It is important to know the diagnostic accuracy of serum amylase, serum lipase, urinary trypsinogen-2, and urinary amylase for the diagnosis of acute pancreatitis, so that an informed decision can be made as to whether the person with abdominal pain has acute pancreatitis. There is currently no Cochrane review of the diagnostic test accuracy of serum amylase, serum lipase, urinary trypsinogen-2, and urinary amylase for the diagnosis of acute pancreatitis...
