Two Gram-stain-positive, rod-shaped, non-motile, catalase-negative and facultative anaerobic strains, NCYUAST and BCRC 18859 (=NRIC 1947), were isolated from cow manure of Taiwan and coconut juice of Philippines, respectively. Comparative sequence analysis of 16S rRNA gene revealed that the novel strains were members of the genus Lactobacillus. These two strains had 100% of 16S rRNA gene sequence similarity and 98.6% of average nucleotide identity (ANI) value based on whole genome sequences. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus casei (99...

Pseudomyogenic hemangioendothelioma (PHE; epithelioid sarcoma-like hemangioendothelioma) is a rare entity, with 129 reported cases. It is a rarely metastasizing, low-grade vascular tumor that can histologically mimic epithelioid sarcoma and often presents as multiple discontinuous nodules in the extremities. PHEs characteristically and consistently show immunoreactivity for cytokeratins and endothelial markers. We present a case in the thigh of a 65-year-old-man with a 3-month history of painful lesions in the dermis and review the published literature...

BACKGROUND: In veterans, post-traumatic stress disorder (PTSD) is often associated with substance abuse, which in turn can lead to cirrhosis. Cirrhotic patients are prone to cognitive impairment, which is typically due to covert hepatic encephalopathy (CHE), but can also be affected by PTSD. The aim was to define the impact of PTSD on cognitive performance and the diagnosis of CHE in cirrhotic patients. METHODS: Outpatient veterans with cirrhosis underwent two separate modalities for CHE cognitive testing [Psychometric Hepatic Encephalopathy Scale (PHES) and Inhibitory Control Test (ICT)]...

Pseudomyogenic hemangioendothelioma (PHE) is an uncommon neoplasm with propensity for local recurrence. The tumor mimics epithelioid hemangioendothelioma and epithelioid sarcoma, representing a possible diagnostic pitfall. We investigated the clinicopathological, immunohistochemical and fluorescence in situ hybridization features of PHEs. Eight cases of PHE were retrieved from our pathology archives. The clinical and outcome information was available in six patients. In six cases the tumors were located in the lower limb while the upper limb was involved in two cases...

The taxonomic position of four phenotypically closely related strains isolated from faecal samples of yaks (Bos grunniens) collected from the Qinghai-Tibetan plateau, China, was determined by a polyphasic approach. The strains were non-spore-forming, non-motile Gram-stain-positive, ovoid cocci, occurring predominantly in pairs and short chains or in irregular clusters. The 16S rRNA gene of strain MN05(T) was related phylogenetically to those of Enterococcushaemoperoxidus, Enterococcusrotai, Enterococcusquebecensis, Enterococcusplantarum, Enterococcuscrotali, Enterococcusmoraviensis, Enterococcussilesiacus, Enterococcuscaccae, Enterococcustermitis, Enterococcusureasiticus and Enterococcusureilyticus, all belonging to the Enterococcusfaecalis species group...

Riemerella anatipestifer, an avian pathogen, has resulted in enormous economic losses to the duck industry globally. Notwithstanding, little is known regarding the physiological, pathogenic and virulence mechanisms of Riemerella anatipestifer (RA) infection. However, the role of Ferric uptake regulator (Fur) in the virulence of R. anatipestifer has not, to date, been demonstrated. Using a genetic approach, unmarked gene deletion system, we evaluated the function of fur gene in the virulence of R. anatipestifer...

BACKGROUND: Psychometric testing is used to identify patients with cirrhosis who have developed hepatic encephalopathy (HE). Most batteries consist of a series of paper-and-pencil tests, which are cumbersome for most clinicians. A modern, easy-to-use, computer-based battery would be a helpful clinical tool, given that in its minimal form, HE has an impact on both patients' quality of life and the ability to drive and operate machinery (with societal consequences). AIM: We compared the Cogstate™ computer battery testing with the Psychometric Hepatic Encephalopathy Score (PHES) tests, with a view to simplify the diagnosis...

A Gram-stain-positive, catalase-negative and short-rod-shaped organism, designated VTT E-94560, was isolated from beer in Finland and deposited in the VTT culture collection as a strain of Lactobacillus rossiae. However, the results of 16S rRNA gene sequence analysis showed that VTT E-94560 was only related to Lactobacillus rossiae JCM 16176(T) with 97.0 % sequence similarity, lower than the 98.7 % regarded as the boundary for the species differentiation. Additional phylogenetic studies on the pheS gene, rpoA gene and 16S-23S rRNA internally transcribed spacer region further reinforced the taxonomically independent status of VTT E-94560 and its related Lactobacillus species including L...

BACKGROUND: Lactic acid bacteria (LAB) are receiving more attention to act as cell factories for the production of high-value metabolites. However, the molecular tools for genetic modifying these strains are mainly vector-based double-crossover strategies, which are laborious and inefficient. To address this problem, several counterselectable markers have been developed, while few of them could be used in the wild-type host cells without pretreatment. RESULTS: The pheS gene encoding phenylalanyl-tRNA synthetase alpha subunit was identified in Lactococcus lactis NZ9000 genome...

The objective of this study was to assess the contamination level of potentially harmful elements (PHEs) in industrial soils and how this relates to environmental magnetism. Moreover, emphasis was given to the determination of the potential mobile fractions of typically "technogenic" metals. Therefore, magnetic and geochemical parameters were determined in topsoils (0-20 cm) collected around a chemical industry in Sindos Industrial Area, Thessaloniki, Greece. Soil samples were presented significantly enriched in "technogenic" metals such Cd, Pb, and Zn, while cases of severe soil contamination were observed in sampling sites north-west of the industrial unit...

OBJECTIVES: Periodic health examinations (PHEs) are the most common reason adults see primary care providers. It is unknown if PHEs serve as a "safe portal" for patients with mental health needs to initiate care. We examined how physician communication styles impact mental health service delivery in PHEs. STUDY DESIGN: Retrospective observational study using audio-recordings of 255 PHEs with patients likely to need mental health care. METHODS: Mixed-methods examined the timing of a mental health discussion (MHD), its quality, and the relationship between MHD quality and physician practice styles...
