Human societies are increasingly and rapidly developing. These changes and revolutions influence human attitudes, world views, values and expectations along with changes in higher education. Universities as one of the most thoughtful institutes are responsible for fulfilling national development objectives. So, as their mission they ought to activate their member organs in accordance with devel...
BACKGROUND The atheromodulating activity of B cells during the development of atherosclerosis is well documented, but the mechanisms by which these cells are regulated have not been investigated. METHODS AND RESULTS Here, we analyzed the contribution of Qa-1-restricted CD8(+) regulatory T cells to the control of the T follicular helper-germinal center B-cell axis during atherogenesis. Genetic...
Hutchinson–Gilford Progeria Syndrome, Werner syndrome, and Cockayne syndrome are three genetic disorders, in which the children have premature aging features. To understand the phenomena of premature aging, the similarity of aging features in the syndromes to that in normal aging is investigated. Although these syndromes have different genetic backgrounds, the patients all have abnormal structu...
The anamniote lateral line system, comprising mechanosensory neuromasts and electrosensory ampullary organs, is a useful model for investigating the developmental and evolutionary diversification of different organs and cell types. Zebrafish neuromast development is increasingly well understood, but neither zebrafish nor Xenopus is electroreceptive and our molecular understanding of ampullary o...
Pelvic floor and perineum muscles play an important role in the formation of apparatus supporting pelvic organs. The functional insufficiency myofascial structures frequently leads to development urinary fecal incontinence, erectile dysfunction, prolapse internal organs, perineal hernias formation. Back 20th century, morphologists focused on skeletal perineum, highlighting their leading organs ...
a larger proportion of energy intake for reproduction and also low food availability maydecrease the growth rate of other organs during the late stage of the gonadal development. themain goal of this study is to examine the biological characteristics and organs growth pattern inclupeonella cultriventris during the late stages of gonad development. samples were collectedby capturing 300-350 kilk...
Tissue engineering and regenerative medicine (TE/RM) represents a broad spectrum of cell and biomaterial based approaches aiming to repair, augment and regenerate diseased tissues and organs. The successful recent clinical implantation of tissue engineered trachea, bladder and bladder derivative (Neo-Urinary ConduitTM) has highlighted the emergence of common methodological frameworks for the de...
The gut associated immune system fences off potentially harmful intestinal antigens from the systemic circulation and induces systemic tolerance against luminal antigens. Intestinal immune responses against luminal antigens include IgA secretion and induction of regulatory cells. Unlike few other cytokines, lymphotoxin alpha/beta regulates the development of intestinal lymphoid organs. The embr...
