Trichinella spiralis has the unique ability to make itself "at home" by creating and hiding in a new type of cell in the host body that is the nurse cell. From this immunologically privileged place, the parasite orchestrates a long-lasting molecular cross talk with the host through muscle larvae excretory-secretory products (ES L1). Those products can successfully modulate parasite-specific imm...

We investigate an electronic marketplace driven by suppliers that survey customer responses, determine market values of products, and sell products. A supplier creates and dispatches a mobile agent to potential buyers. The mobile agent carries with it information about the available stock and the residual price of the product. The objective is to maximize the gross returns to the supplier. The ...

Objective: The aim of this meta-analysis was to determine the effectiveness of neurofeedback treatments in adults with Attention Deficit/ Hyperactivity Disorder (ADHD). Methods: A total of 9 studies were selected, and meta-analysis was done on them. The data were gathered from the following databases: PubMed, ScienceDirect, Springer, SID based on methodological conditions, topic and research d...

Electrical stimulation (ES) of bovine carcasses is usually done to increase tenderness and has been hypothesized to increase the activity of proteolytic enzymes that may degrade structural proteins in muscle cells and cause fractures and breaks in muscle fibers, thus enhancing meat tenderness. Our objective was to compare postmortem (PM) changes in the muscle proteins, titin, nebulin, alpha-act...

BACKGROUND Conditional knockout mice are a useful tool to study the function of gene products in a tissue-specific or inducible manner. Classical approaches to generate targeting vectors for conditional alleles are often limited by the availability of suitable restriction sites. Furthermore, plasmid-based targeting vectors can only cover a few kB of DNA which precludes the generation of targeti...

The orphan nuclear receptor steroidogenic factor 1 (SF-1) is expressed in the adrenal gland and gonads and is an important regulator of the expression of cytochrome P-450 steroidogenic enzymes in cultured cells. Targeted disruption of the SF-1 gene in mice shows that it is a critical participant in the genetic program that promotes the development of urogenital mesoderm into the adrenal gland a...

Teladorsagia circumcincta is an important pathogenic nematode of sheep. It has been demonstrated previously that stimulation of murine T lymphocytes with excretory-secretory (ES) products derived from fourth stage larvae of T. circumcincta (Tci-L4-ES) results in de novo expression of Foxp3, a transcription factor intimately involved in regulatory T cell function. In the current study, Foxp3⁺ T ...
