Although there is now abundant evidence that certain personality features constitute risk factors for negative health outcomes, personality measures have received little attention to date in the behavioral immunology literature. The present study assessed the relationship between major dimensions of personality and tonic cardiovascular, neuroendocrine, and immunologic parameters in 276 healthy ...

Innate immune functions are proposed to develop rapidly post-hatch in altricial nestlings, compared with adaptive immune defenses that require development of receptor specifi city and memory. Studies of ontogenetic changes in altricial birds have been few until relatively recently and often do not encompass the entire developmental period. We examined the patterns of development in constitutive...

An inverse relation exists between melatonin and androgen in most of the seasonally breeding rodents, but the regulation of their receptors in modulation of immune function has never been reported. The present study accessed the expression pattern of melatonin receptor types (mt1R & mt2R), immune parameters (lymphoid organs weight, leucocyte count, delayed type hypersensitivity and lymphocyte p...

Several humoral immune factors were studied in a group of cultured halibut (Hippoglossus hippoglossus L.). The serum protein and IgM concentration was comparable to levels seen in other teleost species. A strong antibody activity against TNP-BSA was observed but not against other antigens tested. Lysozyme and anti-protease activity was detected and showed variable heat sensitivity. Unlike the a...

INTRODUCTION The rapid increase on life-expectancy represents a major challenge and economic burden for modern societies. Several studies have focused on the effects of polyunsaturated fatty acids (PUFA) upon the immune system; however less attention has been paid to the effects of monounsaturated fatty acids (MUFA). In this work we investigated the relationship of habitual consumption of diffe...

In vitro basophil responses have long been used in mechanistic studies to help assess the human allergic diathesis, particularly during therapeutic intervention. Recent evidence points to the use of dendritic cells (DCs) in also being valuable in evaluating therapies aimed at lessening disease through immunomodulation. This review article therefore takes a look at some of the recent advances in...

Extensive and informative immunological assessments of islet transplant recipients have been limited due, in part, to the smaller numbers of patients transplanted compared with solid organ trials. Limitations related to blood volume and the logistical challenges of collecting multiple posttransplant samples for drug levels as well as clinical and metabolic parameters also pose challenges. Sever...

this experiment was conducted in order to evaluate the effect of different levels of malva sylvestris extract on performance, carcass characteristics and some immune and blood parameters of broiler chickens with 16 experimental units with 4 treatment, 4 replicate and 11 broilers in each replicate  in completely randomized design for 42 days. the dietary treatments consisted of basal diet (contr...
