Metal oxide gas sensors with integrated micro-hotplate structures are widely used in the industry and they are still being investigated and developed. Metal oxide gas sensors have the advantage of being sensitive to a wide range of organic and inorganic volatile compounds, although they lack selectivity. To introduce selectivity, the operating temperature of a single sensor is swept, and the measurements are fed to a discriminating algorithm. The efficiency of those data processing methods strongly depends on temperature uniformity across the active area of the sensor...

This work investigated the frequently observed "rebounds" of contaminants of concern in groundwater systems. Specifically, influences of bioaugmented microorganisms on the sorption and desorption of representative petroleum constituents [benzene, 1,3,5-trimethylbenzene and naphthalene (BTN)] were studied in freshly-spiked and historically-contaminated sediments. Capable microorganisms were enriched and supplemented to contaminated sediments to enhance biodegradation of petroleum hydrocarbons. In freshly-spiked sediments, when petroleum-degrading microorganisms were added, concentrations of dissolved petroleum constituents appeared to increase initially, and 12...

Butyrophilin molecules (commonly contracted to BTN), collectively take their name from the eponymous protein in cow's milk. They are considered to be members of the B7 family of costimulatory receptors, which includes B7.1 (CD80), B7.2 (CD86), and related molecules, such as PD-L1 (B7-H1, CD274), ICOS-L (CD275), and B7-H3 (CD276). These coreceptors modulate T cell responses upon antigen presentation by major histocompatibility complex and cognate αβ T cell receptor engagement. Molecules such as BTN3A1 (CD277), myelin oligodendrocyte glycoprotein, and mouse Skint1 and Btnl2, all members of the butyrophilin family, show greater structural and functional diversity than the canonical B7 receptors...

A gold millielectrode (GME) functionalized with a mixed (16-MHA + EG3SH) self-assembled monolayer (SAM) was used to fabricate an indirect enzyme-linked immunosorbent assay (ELISA) immunosensor for the sensitive detection of prostate-specific antigen (PSA), a prostate cancer (PCa) biomarker, in human serum samples. To address and minimize the issue of non-specific protein adsorption, an organic matrix (amine-PEG3-biotin/avidin) was assembled on the previously functionalized electrode surface to build up an ordered and hierarchically organized interfacial supramolecular architecture: Au/16-MHA/EG3SH/amine-PEG3-biotin/avidin...

TROP-2 is a type I transmembrane glycoprotein which is over-expressed in various malignancies, and is related to epithelial cell adhesion molecule (EpCAM), also called TROP-1, gp40, and KSA. In this study, we evaluated TROP-2 expression in papillary thyroid carcinoma (PTC) and compared it to other thyroid neoplastic and non-neoplastic lesions. Immunohistochemical (IHC) evaluation for TROP-2 was performed on 137 thyroid fine needle aspiration (FNA) cell blocks (CB) which included classic PTC (64), follicular variant PTC (FVPTC) (10), anaplastic thyroid carcinoma (AC) (2), medullary carcinoma (MC) (8), follicular neoplasms (FN) (8), Hurthle cell neoplasms (HCN) (9), follicular lesion of uncertain significance (FLUS) (12), and benign thyroid nodule (BTN) (24)...

Vγ2Vδ2 T cells play important roles in human immunity to pathogens and in cancer immunotherapy by responding to isoprenoid metabolites, such as (E)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate and isopentenyl pyrophosphate. The Ig superfamily protein butyrophilin (BTN)3A1 was shown to be required for prenyl pyrophosphate stimulation. We proposed that the intracellular B30.2 domain of BTN3A1 binds prenyl pyrophosphates, resulting in a change in the extracellular BTN3A1 dimer that is detected by Vγ2Vδ2 TCRs...

In this study, bovine mammary epithelial cells were used to study stress responses after cells were exposed to 42°C for 0.5, 1, 3, 5, 8 or 12 h, and 38°C as control. The transcription of the genes (HSP27, HSP70 and HSP90) of heat shock protein (Hsp) was significantly enhanced under heat stress (HS). The peak transcription of HSP70 was 14 times the control at 1 h. Expression of proteins Hsp27 and Hsp70 was gradually increased under HS, with rapid deposition of Hsp70 in epithelial cells. The major milk protein genes of β-casein (CSN2) and butyrophilin (BTN1A1) were down-regulated and the synthesis of total caseins was decreased...

Platelet-activating factor (PAF), a potent lipid mediator, is implicated in many inflammatory diseases, and therefore may serve as a direct target for anti-inflammatory drugs. We previously reported that synthetic biotinylated peptides having a Tyr-Lys-Asp-Gly sequence markedly inhibit PAF-induced inflammation by direct binding, and that two synthetic fluorescence-labelled heptapeptides (Lys-Trp-Tyr-Lys-Asp-Gly-Asp and D-Lys-Trp-Tyr-Lys-Asp-Gly-Asp) with high stability in plasma specifically bind to PAF-like lipids (oxidized- and lyso-phosphatidylchoine)...

Ischemia in the immature brain is an important cause of neonatal seizures. Temporal evolution of acquired neonatal seizures and their response to anticonvulsants are of great interest, given the unreliability of the clinical correlates and poor efficacy of first-line anti-seizure drugs. The expression and function of the electroneutral chloride co-transporters KCC2 and NKCC1 influence the anti-seizure efficacy of GABAA-agonists. To investigate ischemia-induced seizure susceptibility and efficacy of the GABAA-agonist phenobarbital (PB), with NKCC1 antagonist bumetanide (BTN) as an adjunct treatment, we utilized permanent unilateral carotid-ligation to produce acute ischemic-seizures in post-natal day 7, 10, and 12 CD1 mice...

Recently, butyrophilin (BTN) - a protein which shares cross-reactive epitopes with myelin oligodendrocyte glycoprotein (MOG) - has been found in milk. A high amount of milk BTN has been reported in the outer membrane of vesicular structures known as exosome and milk fat globule membrane (MFGM). These vesicles can act as Trojan horses, passing their BTN content through epidermis or other biologic barriers of the body. By altering the dose schedule and route of administration, the BTN-bearing vesicles (exosomes and MFGMs) may acquire enough potential to be used in MOG-specific immunotherapy program...

Host-viral genetic interaction has a key role in hepatitis C infection (HCV) and maybe in the viral selection. In a preliminary GWAS analysis, we identified BTN3A2 rs9104 to be associated with HCV genotype 1. Therefore, our aim was to determine the influence of BTN family on the selection of HCV genotype. We performed a fine-mapping analysis of BTN gene region in a cohort of chronic HCV infection (N=841), validating significant results in another independent chronic HCV infection cohort (N=637), according to selection of viral genotype...
