BACKGROUND Several species of trichomonads are intestinal or urogenital parasites of humans and animals, with only a few species typically being located in the oral cavity. The prevalence of oral trichomoniasis in dogs is approximately 15-25 %, although the prevalence varies among different populations and depends on age, sex and the health of the oral cavity. CASE PRESENTATION A case of mand...

The genomes of the related crenarchaea Pyrobaculum aerophilum and Thermoproteus tenax lack any obvious gene encoding a single-stranded DNA binding protein (SSB). SSBs are essential for DNA replication, recombination, and repair and are found in all other genomes across the three domains of life. These two archaeal genomes also have only one identifiable gene encoding a chromatin protein (the Al...

Gloiopeltis tenax (G. tenax) is widely distributed along the Chinese coastal areas and is commonly used in the treatment of diarrhea and colitis. This study aimed at investigating the bioactivities of the volatile constituents in G. tenax. We extracted the essential constituents of G. tenax by supercritical carbon dioxide extraction (CO₂-SFE), then identified and analyzed the constituents by ga...

Tenax-resin has been originally developed for grabbing volatile organic compounds from gases. The resin is a porous polymer (2,6-diphenyl-p-phenylene oxide) and it has low affinity for water (floats on the surface). It has high affinity for hydrophobic organic contaminants (HOCs), thus capturing them efficiently from water. On the other hand, the HOCs can be quite easily be extracted from Tenax...

The role of the disaccharide trehalose, its biosynthesis pathways and their regulation in Archaea are still ambiguous. In Thermoproteus tenax a fused trehalose-6-phosphate synthase/phosphatase (TPSP), consisting of an N-terminal trehalose-6-phosphate synthase (TPS) and a C-terminal trehalose-6-phosphate phosphatase (TPP) domain, was identified. The tpsp gene is organized in an operon with a put...

background: trichomonas tenax, a commensal flagellated protozoan, inhabits in human oral cavity. this parasite is cos-mopoli­tan and frequently found in patients with poor oral hygiene and advanced periodontal disease. there is only one pub­lished study that rebound the prevalence of this parasite in iran. this pcr based study compared the prevalence of oral tricho­moni­asis in patients with or...

The objective of this study was to compare the adsorption/desorption of target compounds on homemade electrospun nanofibers, polystyrene (PS) nanofibers, acrylic resin (AR) nanofibers and PS-AR composite nanofibers with Tenax TA. Ten volatile organic compounds (VOCs) were analyzed by preconcentration onto different sorbents followed by desorption (thermal and solvent orderly) and analysis by ca...

Its frequency was 9% among the examined swabs. There were 50% infection rates for both males as well females. The highest incidence (11.25%) found 21-40 years-old while lowest (6.66%) in 41-60 years-old. no significant variations relation to residency. association between T. tenax and dental caries noticed at a rate of 66.7%. In addition, different observed patients with some other oral disease...

Eristalis tenax, belonging to order Diptera, family Syrphidae seldomly causes intestinal myiasis. Intestinal myiasis caused by E. tenax larvae is a rare manifestation found in both humans and other vertebrate animals. We report a 22-year-old woman presented with this myiasis. The larva in her stool sample was identified as E. tenax related to its typical morphology and authentic clues. Lack of ...

A kind of new multi-layer adsorbent including Tenax TA/multi-walled carbon nanotubes (MWCNTs)/Carboxen 564 was developed for collecting volatile organic compounds. The adsorption and desorption efficiencies of 11 kinds of adsorbents (including Activated charcoal, Tenax TA, Carboxen 564, Chromosorb 101, Chromosorb 102, Chromosorb 103, Chromosorb 105, Porapak Q, GDX 301, XAD-2, and MWCNTs) were c...
