The trace element selenium (Se) is essential for immune system development and function in animals. However, the exact functions of Se in the human immune system and the achievable health benefits from Se supplementation remain unclear. To test whether an increased intake of dietary Se affects immune function, we conducted a randomized, controlled trial of Se supplementation in healthy free-liv...

Clinical observations indicate that the antibody response to herpes simplex virus (HSV) in patients undergoing acyclovir treatment is reduced and, although the exact mechanism is not clear, some authors interpret it as immunosuppression. In order to clarify the mechanism, we cutaneously infected mice with HSV-1 and treated the resulting skin lesions with acyclovir. The immune response to infect...

BACKGROUND It was recently reported that iron oxide nanoparticles attenuated antigen-specific humoral responses and T cell cytokine expression in ovalbumin-sensitized mice. It is presently unclear whether iron oxide nanoparticles influence T helper 1 cell-mediated immunity. The present study aimed to investigate the effect of iron oxide nanoparticles on delayed-type hypersensitivity (DTH), whos...

Activated T lymphocytes play a crucial role in orchestrating cellular infiltration during a cell-mediated immune (CMI) reaction. TCA3, a C-C chemokine, is produced by Ag-activated T cells and is chemotactic for neutrophils and macrophages, two cell types in a murine CMI reaction. Using a gelatin sponge model for delayed-type hypersensitivity (DTH), we show that TCA3 is a component of the expres...

Günümüzde dış ticaret, ülkelerin kalkınmalarının sürdürülmesinde ve dünya ülkeleriyle bütünleşmenin sağlanmasında en önemli unsurlardan biri olarak görülmektedir. Özellikle, ekonomik kalkınma sürecinde, iç dinamikleri harekete geçiren ticaretin rolü çok fazladır. Küreselleşmenin fırsatlarından yararlanmak isteyen az gelişmiş gelişmekte olan ülkeler, ticaret yoluyla kazanımlar elde etmeyi başarı...

Journal: :Journal of Vibroengineering 2022

This paper presents a novel pneumatic Down-The-Hole (DTH) hammer with self-rotation bit used for rock drilling, and the mechanical structure working principle are mainly covered. A unique mechanism ratchet pawl incorporated in DTH is proposed percussion-rotation drilling to break rock. The drill can rotate while pipe stays still because of design reduces friction between borehole. Firstly, rati...

The entity of chronic daily headache (CDH) is well documented, but is not included in the current classification. We divided patients with CDH into groups with and without migrainous features. This division resulted in clearly distinguishable syndromes of daily migrainous headaches (DMH) and daily tension-type headaches (DTH). Family history of headaches was more common in patients with DMH. Pa...

The suppressor pathway that regulates the T cell response to p-azobenzenearsonate (ABA)-coupled cells has been studied. It has been found that the ability of anti-idiotypic second-order T suppressor cells (Ts2) to inhibit T cell-dependent delayed-type hypersensitivity (DTH) responses depended upon the presence of cross-reactive-idiotype (CRI)-bearing T cells present in ABA-primed mice. This sup...

Calorie restriction (CR) enhances immune response and prolongs life span in animals. However, information on the applicability of these results to humans is limited. T-cell function declines with age. We examined effects of CR on T-cell function in humans. Forty-six overweight, nonobese participants aged 20-42 years were randomly assigned to 30% or 10% CR group for 6 months. Delayed-type hypers...

4-Hydroxy-3-nitrophenyl acetyl (NP)-derivatized syngeneic spleen cells administered intravenously induced a population of suppressor T cells that could suppress mice previously primed to NP. The effect was demonstrable when the suppressor cells were transferred to NP-primed mice on the day of challenge for delayed-type hypersensitivity (DTH) responses. In contrast to the suppressor T cell popul...
