Tritrichomonas foetus (T. foetus) is a flagellated protozoa that infects the distal ileum and proximal colon of domestic cats, as well as the urogenital tract of cattle. Feline trichomonosis is recognized as a prevalent cause of chronic diarrhea in cats worldwide. The suspected route of transmission is fecal-oral, with cats in densely crowded environments at highest risk for infection. Thus, the recommended strategy for minimizing spread of infection is to identify and isolate T. foetus-positive cats from the general population...

BACKGROUND: Point-of-care (POC) testing is highly useful when treating critically ill patients. In case of difficult vascular access, the intraosseous (IO) route is commonly used, and blood is aspirated to confirm the correct position of the IO-needle. Thus, IO blood samples could be easily accessed for POC analyses in emergency situations. The aim of this study was to determine whether IO values agree sufficiently with arterial values to be used for clinical decision making. METHODS: Two samples of IO blood were drawn from 31 healthy volunteers and compared with arterial samples...

Brazil has a large population with a high waste generation. The municipal solid waste (MSW) generated is deposited mainly in landfills. However, a considerable fraction of the waste is still improperly disposed of in dumpsters. In order to overcome this inadequate deposition, it is necessary to seek alternative routes. Between these alternatives, it is possible to quote gasification and incineration. The objective of this study is to compare, from an energetic and economic point of view, these technologies, aiming at their possible implementation in Brazilian cities...

Two neutral cyclometalated Ir(iii)-tetrazolato complexes that differ by variations of the substituents on either the phenylpyridine or the tetrazolate ligand have been converted into the corresponding methylated and cationic analogues. NMR ((1)H and (13)C) characterization of the Ir(iii) complexes provided the results in agreement with the chemo- and regioselective character of methylation at the N-3 position of the Ir(iii)-coordinated tetrazolato ring. This evidence was further corroborated by the analysis of the molecular structures of the cationic complexes obtained by X-ray diffraction...

Ochatoxin A (OTA) is one of the most important mycotoxins based on its toxicity. The oral route is the main gateway of entry of OTA into the human body, and specialized epithelial cells constitute the first barrier. The present study investigated the in vitro cytotoxic effect of OTA (5, 15 and 45 μM) and production of OTA metabolities in Caco-2 and HepG2 cells using a co-culture Transwell System to mimic the passage through the intestinal epithelium and hepatic metabolism. The results derived from MTS cell viability assays and transepithelial electrical resistance measurements showed that OTA was slightly cytotoxic at the lowest concentration at 3 h, but significant toxicity was observed at all concentrations at 24 h...

Porcine reproductive and respiratory syndrome (PRRS) has caused huge economic losses to Chinese swine industry and remains a major threat since it was first reported in 1996. However, investigations of molecular epidemiological and genetic diversity of PRRS viruses (PRRSVs) in China were limited to a small number of representative strains collected in several areas. Moreover, lineage classifications reported by individual researchers were quite different. In the present study, we sequenced ORF5 sequences of 217 PRRSVs from clinical samples, retrieved all the available ORF5 sequences of PRRSVs isolated in China in 1996-2016 (n=2213) from GenBank, and systematically analyzed corresponding epidemiological data...

Kambo is a substance obtained from the skin secretions of a frog, Phyllomedusa bicolor, popular in the Amazon region, which is administered via the transdermal route. We report a case of 42-year-old man found dead in his house. Near the corpse, a plastic box labeled as "Kambo sticks" was found. The man was a chronic consumer of Kambo and no previous pathology or genetic disease emerged in clinical history from the declaration of his general practitioner. Autopsy investigations and toxicological analysis were performed...

PURPOSE: Tedizolid phosphate is a next-generation oxazolidinone prodrug that is transformed into the active moiety tedizolid. Its indication is acute bacterial skin and skin structure infections caused by gram-positive species, including methicillin-resistant Staphylococcus aureus. Although tedizolid phosphate has been marketed in Korea, no data on the pharmacokinetic (PK) properties or tolerability of tedizolid phosphate in Korean subjects are available. This study was designed to evaluate the PK properties, oral bioavailability, and tolerability with a single-dose oral and intravenous administration of tedizolid phosphate in healthy Korean male subjects...

Mitochondrial respiratory chain complex I consists of 44 different subunits and can be subgrouped into three functional modules: the Q-, the P- and the N-module. NDUFAF4 (C6ORF66) is an assembly factor of complex I that associates with assembly intermediates of the Q-module. Via exome sequencing, we identified a homozygous missense variant in a complex I-deficient patient with Leigh syndrome. Supercomplex analysis in patient fibroblasts revealed specifically altered stoichiometry. Detailed assembly analysis of complex I, indicative of all of its assembly routes, showed an accumulation of parts of the P- and the N-module but not the Q-module...

BACKGROUND: Metritis is an inflammatory disease of the uterus caused by bacterial infection, particularly Bacteroides, Porphyromonas, and Fusobacterium. Bacteria from the environment, feces, or vagina are believed to be the only sources of uterine contamination. Blood seeps into the uterus after calving; therefore, we hypothesized that blood could also be a seeding source of uterine bacteria. Herein, we compared bacterial communities from blood, feces, and uterine samples from the same cows at 0 and 2 days postpartum using deep sequencing and qPCR...

Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary pathogen of enzootic pneumonia, a chronic respiratory disease in pigs. Infections occur worldwide and cause major economic losses to the pig industry. The present paper reviews the current knowledge on M. hyopneumoniae infections, with emphasis on identification and analysis of knowledge gaps for optimizing control of the disease. Close contact between infected and susceptible pigs is the main route of M. hyopneumoniae transmission. Management and housing conditions predisposing for infection or disease are known, but further research is needed to better understand M...

The efficacy and safety of glycoprotein IIb/IIIa inhibitors via intracoronary (IC) route versus the intravenous (IV) route are not well known. We conducted this meta-analysis of randomized trials evaluating the role of IC versus IV glycoprotein IIb/IIIa in patients undergoing primary percutaneous coronary intervention. The analysis included 14 trials with a total of 3,754 patients. The primary outcome of major adverse cardiac events (MACE) had no statistically significant difference between the IC and the IV groups (relative risk [RR] 0...

Hepatitis E virus (HEV) causes acute or chronic hepatitis in humans and can be transmitted via the fecal-oral route. Pigs are one of the main reservoirs for this infection. Sixty pigs, 4-5 months of age, on a swine herd in Japan had detectable anti-HEV IgG antibodies, and five (8.3%) of them had ongoing infection of genotype 3 HEV. Five HEV strains obtained from the viremic pigs shared 98.8-100% nucleotide identity, and one representative strain (swHE1606845), whose entire genomic sequence was determined in this study, differed by 14...

Colorectal cancer (CRC) is the second leading cause of cancer death worldwide, and immune checkpoint blockade therapy provides an opportunity for improving the outcome of CRC patients. Recent studies suggest that programmed death ligand-1 (PD-L1) is only expressed in 12% of CRCs. Here, we demonstrate that PD-L2 is expressed in approximately 40% CRCs, and its expression independently associates with poor survival of CRC patients. By detection of PD-L2 expression by immunofluorescence in 124 CRC cases with 10-y survival data, we found significant association between PD-L2 overexpression in cancer cells and worse overall survival (46...

Nanoclays' functionalization with organic modifiers increases their individual barrier properties, thermal stability, and mechanical properties and allows for ease of implementation in food packaging materials or medical devices. Previous reports have shown that, while organic modifiers integration between the layered mineral silicates leads to nanoclays with different degrees of hydrophobicity that become easily miscible in polymers, they could also pose possible effects at inhalation or ingestion routes of exposure...

Lassa virus (LASV) causes a severe hemorrhagic fever endemic throughout western Africa. Because of the ability to cause lethal disease in humans, limited treatment options, and potential as a bioweapon, the need for vaccines to prevent LASV epidemic is urgent. However, LASV vaccine development has been hindered by the lack of appropriate small animal models for efficacy evaluation independent of biosafety level four (BSL-4) facilities. Here we generated an LASV-glycoprotein precursor (GPC)-pseudotyped Human immunodeficiency virus containing firefly luciferase (Fluc) reporter gene as surrogate to develop a bioluminescent-imaging-based BALB/c mouse model for one-round infection under non-BSL-4 conditions, in which the bioluminescent intensity of Fluc was utilized as endpoint when evaluating vaccine efficacy...

In 2014 we observed a noticeable increase in sudden deaths of green tree pythons (Morelia viridis). Pathological examination revealed accumulation of mucoid material within airways and lung, associated with enlargement of the entire lung. We performed full necropsy and histological examination on 12 affected green tree pythons from 7 different breeders to characterise the pathogenesis of this "mucinous" pneumonia. By histology we could show a marked hyperplasia of the airway epithelium and of faveolar type II pneumocytes...
