The induction of strong CD8(+) T-cell responses against infectious diseases and cancer has remained a major challenge. Depending on the source of antigen and the infectious agent, priming of CD8(+) T cells requires direct and/or cross-presentation of antigenic peptides on major histocompatibility complex (MHC) class I molecules by professional antigen-presenting cells (APCs). However, both path...

Ciliates within the Mesodinium rubrum/Mesodinium major species complex harbor chloroplasts and other cell organelles from specific cryptophyte species. was recently described, new studies indicate that blooms of M. are just as common rubrum. Despite this, physiology has never been studied compared to In this study, growth, food uptake, chlorophyll a photosynthesis were measured at six different...

35 patients with unilateral sensorineural impairment and hearing levels within the normal range in the opposite ears were investigated by bilateral transtympanic electrocochleography (TIECoG). Only 19 patients (54%) satisfied the criteria for Meniere's disease and 16 patients (46%) showed sensorineural impairment due to other etiologies. Clinical studies have focused exclusively on the a mp...

ABSTRACT In this study, we isolated and characterized HSP70 cDNA from pufferfish (Takifugu rubripes). The 3053 bp full-length TrHSP70 sequence consisted of a 167 5′-UTR (untranslated region), 2535 open reading frame, 351 3′-UTR. BLAST analysis revealed that the shared high similarity with sequences in other species. our set 3 experimental groups as H1 group (20 °C), H2 (24 H3 (28 °C) for checki...

We investigated the negative effect of type I IFN (IFN-I) on the priming of specific CD8 T cell immunity. Priming of murine CD8 T cells is down-modulated if Ag is codelivered with IFN-I-inducing polyinosinic:polycytidylic acid (pI/C) that induces (NK cell- and T/B cell-independent) acute changes in the composition and surface phenotype of dendritic cells (DC). In wild-type but not IFN-I recepto...

Type I interferons (IFN-I) are expressed in the brain during many inflammatory and neurodegenerative conditions and have multiple effects on CNS function. IFN-I is readily induced in the brain by systemic administration of the viral mimetic, poly I:C (synthetic double-stranded RNA). We hypothesised that IFN-I contributes to systemically administered poly I:C-induced sickness behaviour, metaboli...

The performance of a product is often evaluated by several quality characteristics.  ptimizing the manufacturing process with respect to only one quality characteristic will not always lead to the optimum values for other characteristics. Hence, it would be desirable to improve the overall quality of a product by improving quality characteristics, which are considered to be important. The probl...

BACKGROUND The basic premise of preadjusted bracket system is accurate bracket positioning. It is widely recognized that accurate bracket placement is of critical importance in the efficient application of biomechanics and in realizing the full potential of a preadjusted edgewise appliance. AIM The purpose of this study was to design a calibrating system to accurately detect a point on a plan...
