In relation to consumer demand, crustaceans and cephalopods are sold as both fresh and defrosted. It is well known that total volatile basic nitrogen (TVB-N) and volatile amine values, especially, biogenic amines and biogenic amine index, are expression of freshness of fish products, but there is a lack of knowledge of their acceptability limits, for crustaceans and cephalopods. In order to ass...

Avian leukosis virus (ALV) is an oncogenic virus causing a variety of neoplasms in chickens. The group of avian leukosis virus in chickens contains six closely related subgroups, A to E and J. The prevalence of ALVs in hosts may have imposed strong selective pressure toward resistance to ALVs infection. The tvb gene encodes Tvb receptor and determines susceptibility or resistance to the subgrou...

BACKGROUND microRNAs (miRs)-371-3 are suggested to be novel biomarkers of germ cell tumors (GCTs), but their specificity is unresolved. We aimed at clarifying the origin of miR 371a-3p by measuring this miR in peripheral vein blood, and in fluids present in the vicinity of GCTs. METHODS miR-371a-3p levels were measured by quantitative PCR in 9 tumor surrounding hydroceles and in cubital vein ...

The transcription factor Blimp-1 has emerged as a regulator of cell fate in embryonic (germ cell) and adult (Band T-cell immune effector and epithelial) lineages. It has also been proposed to act as a tumor suppressor in B-cell malignancy. Here, we present a novel in vivo system enabling the targeted genetic manipulation of cells expressing Prdm1, the gene encoding Blimp-1. We created bacterial...

This study was aimed to determine the changes of the local anchovy meal which is known as hamsi kaygana in Turkey during cold storage at +4°C ± 1°C. Physicochemical (pH, TVB-N, TMA-N, and TBA) shelf life analyses were carried out for hamsi kaygana samples. It was confirmed that the pH values obtained from research groups were within the limit values of the literature. No statistically significa...

* Sports commentators at ATV and TVB offered invaluable insights. They are not responsible for my errors, and vice versa.

Changes in total volatile bases (TVB), dimethylamine (DMA), formaldehyde (FA), trimethylamine (TMA) and trimethylamine oxide (TMAO) of whole hake (Merluccius merluccius L.) were evaluated at different temperatures of storage: -5, -12 and -20°C. Significant changes in TVB, DMA, TMA, TMAO nitrogen and FA were observed at 5°C. Only TMAO changed significantly at -12°C and -20°C. TMAO decrease was n...

Successful targeting methods represent a major hurdle to the use of retroviral vectors in cell-specific gene-delivery applications. We recently described an approach for retroviral targeting with a retroviral receptor-ligand bridge protein that was bound to the cognate cell-surface ligand receptors before viral challenge. We now report a significant improvement made to this viral targeting meth...

This is the second paper in a series in which we construct and analyze a class of TVB (total variation bounded) discontinuous Galerkin finite element methods for solving conservation laws ut + Ed I(fi(u))xi = 0. In this paper we present a general framework of the methods, up to any order of formal accuracy, using scalar one-dimensional initial value and initial-boundary problems as models. In t...
