Resumen

La mondialisation des marchés impose une pression accrue envers la performance, la productivité et la profitabilité des entreprises. Cette nouvelle réalité se traduit, entre autres, par une accentuation du travail du savoir ainsi que par une diminution du temps passé au lit. De plus, l’activité physique peut être considérée à juste titre comme une composante du mode de vie qui a été malheureusement laissée de côté et qui doit être minimalement réinsérée dans les activités de tous les jours. En effet, l’activité physique est porteuse d’une stimulation corporelle qui affecte significativement le

Resumen

Ginseng is a popular herbal remedy that is reputed to increase resistance to stress and improve immune function. Regular exercise results in acute physiologic stress that affects the immune response. This study was conducted to investigate the effects of daily consumption of a standardized ginsenoside-containing North American ginseng (Panax quinquefolius) extract on immune function before, during, and after a moderate-exercise protocol in healthy sedentary men. Ten healthy males were randomized to receive either ginseng (1125 mg·d–1) or placebo for 35 days. After a 3 month washout period, sub

In this study, criteria are used to identify whether a subject has elicited maximal oxygen uptake. We evaluated the validity of traditional maximal oxygen uptake criteria and propose a novel set of criteria.

Traditional and novel maximal oxygen uptake criteria were evaluated.

Resumen

A decline in the human immune system that occurs with aging is known as immunosenescence. Several factors are involved in the process, including reduced neutrophil function and cytotoxic capacity of natural killer (NK) cells, thymus atrophy and reduced naïve T cell number, and lowered B cell antibody production in response to antigen. The endocrine system, specifically the hypothalamus–pituitary–adrenal axis, plays an important role in modulating immune function. With aging an imbalance occurs between two adrenal hormones, cortisol and DHEA, that have opposing actions on immune function. This

Abstract Human T-cell lymphotropic virus type 1 (HTLV-1)-specific CTL are thought to be immune effectors that reduce the risk of adult T-cell leukemia (ATL). However, in vivo conditions of anti-HTLV-1 CTL before and after ATL development have yet to be determined. To characterize anti-HTLV-1 CTL in asymptomatic HTLV-1 carriers (AC) and ATL patients, we analyzed the frequency and diversity of HTLV-1-specific CD8+ T cells in PBMC of 35 AC and 32 ATL patients using 16 distinct epitopes of HTLV-1 Tax or Env/HLA tetramers along with intracellular cytolytic effector molecules (IFN-γ , perforin, and

Background: Adjuvant chemotherapies are commonly used for treating early-stage breast cancer. However, whether chemotherapeutic regimens affect exercise tolerance and cardiovascular responses remains unclear. Therefore, we investigated the effects of receiving CAF and AC-T on exercise tolerance and cardiovascular responses in patients with early-stage breast cancer. Methods: Thirty-four patients with breast cancer (age: 44 ± 1 years; stage I-II) received either CAF (n = 15) or AC-T (n = 19), depending on clinical decisions.

Abstract In our study, we have measured in vitro proliferation and IL-2 production by human PBL to characterize the interactions between Th cells and accessory cells (AC) involved in responses to either conventional Ag or alloantigens. IL-2 production and proliferative responses to conventional Ag, such as influenza or tetanus, are exclusively dependent on the presence of CD4+ T cells and AC. In contrast, IL-2 and proliferative responses to alloantigen can be mediated by either CD4+ or CD8+ T cells.

The relatively strong SOI of silicene was demonstrated to induce a topological quantum edge state in the nanosystems by the local density of states, which eliminates the AC emittance response at the Dirac point.

Abstract Allergic conjunctivitis (AC) is a frequent disease that affects the ocular surface, The study of immune physiopathology of allergic conjunctivitis is focused on T helper cells. Recently it has been suggested that γδ T lymphocytes are necessary for the maintenance of the ocular allergic response, however there are not studies in humans about the role of γδ T lymphocytes in human AC. The aim of this study was to evaluate the frequency of γδ T cells and chemokines in tears of AC patients. Patients: 31 patients were included (16 men and 15 women), AC diagnosis was based on clinical histor

Resumen

Abstract Monoclonal antibody (MAb) GT2 defines a unique epitope on the CD2 molecule. GT2 triggers T cell mitosis in combination with any MAb directed against 9.6/T11(1) or D66, two previously defined CD2 epitopes. We have shown already that accessory cells (AC) are required for plenary T-PBL activation by any pair of Ab directed against D66 + 9.6/T11(1). In this study, we further investigated their role and found it to vary with the anti-CD2 pair used. When purified T-PBL preparation is used, the level of [3H]TdR incorporation observed with anti-(GT2 + 9.6/T11(1)) Ab was not significant; howev

Resumen

Viral myocarditis (VMC) is a common disease characterized by cardiac inflammation. AC-73, an inhibitor of CD147, disrupts the dimerization of CD147, which participates in the regulation of inflammation. To explore whether AC-73 could alleviate cardiac inflammation induced by CVB3, mice were injected intraperitoneally with AC-73 on the fourth day post-infection (dpi) and sacrificed on the seventh dpi. Pathological changes in the myocardium, T cell activation or differentiation, and expression of cytokines were analyzed using H&E staining, flow cytometry, fluorescence staining and multiplex

Resumen

The investigation of a Brownian particle subjected to an AC force that diffuses within a T-shaped chamber was conducted. This T-shaped chamber is composed of a strip cavity and a trapezoidal cavity positioned below it. The interplay between the AC force and asymmetric geometry creates a spatially bistable potential perpendicular to the AC force. With the assistance of noise, the particles can transition between two stable states and oscillate along the AC force at corresponding amplitudes at every spatially stable state. The asymmetric geometry facilitates the trapezoid cavity’s ability to mor

Primary chemotherapy sensitivity is best determined from the neoadjuvant setting, therefore we sought to determine if HR+ primary tumors are less sensitive to taxane chemotherapy than HR- tumors.

Abstract We have assessed the inhibitory effects of various monoclonal antibodies on the expression of the IL 2 receptor. Anti-LFA-1, but not anti-Ly-2, markedly inhibited the induction of the IL 2 receptor on the Ly-2+ subset. T-depleted spleen cells, L cells, and B lymphoma cells all functioned as potent accessory cells (AC) for the induction of the IL 2 receptor on L3T4+ T cells. Anti-LFA-1 inhibited the induction of the IL 2 receptor irrespective of the type of AC used. Anti-L3T4 only inhibited the induction of IL 2 receptor expression when L cells were the source of AC.

Anti-CD3 was unable to induce activation of AC-depleted T cells as determined by IL 2 receptor expression, IL 2 production, cell cycle analysis, or detectable DNA synthesis.
