We show that Indian Hedgehog (Ihh) regulates T-cell development and homeostasis in both fetal and adult thymus, controlling thymocyte number. Fetal Ihh(-/-) thymi had reduced differentiation to double-positive (DP) cell and reduced cell numbers compared with wild-type littermates. Surprisingly, fetal Ihh(+/-) thymi had increased thymocyte numbers and proportion of DP cells relative to wild type...

Double pylorus (DP) is a rare condition that is usually discovered incidentally through an upper endoscopy (UE) examination. While acquired DP, which is the most common type, often develops as a complication of peptic ulcer disease (PUD), congenital DP can be isolated associated with other congenital abnormalities such as heterotopic pancreatic tissue or gastric duplication [1, 2]. This article...

An efficient graphical acoustic computing (GRACO) method is introduced. Referring to the rendering of semi-transparent objects, depth peeling (DP) technique compounded with GRACO method, forming a combined and DP (GRACO–DP) consider backscattering multiple-layered structures in which contributions inner are included. After that, some examples GRACO–DP tested evaluate accuracy efficiency such me...

In the absence of selection, CD4+, CD8+ double-positive (DP) thymocytes will die after 3-4 days. The mechanism for regulating the life span of DP cells is unknown. Previously, we demonstrated that the zinc finger transcription factor, early growth response gene 3 (Egr3), promotes proliferation during the transition from double negative (DN) to DP. In this study we demonstrate a novel role for E...

Double pylorus (DP) is a rare condition characterized by the presence of two openings from the gastric antrum to the duodenal bulb, which may be congenital or acquired. Herein, we describe a case of DP in a cirrhotic patient.

Aim: The present study aimed to analyze if the exergaming exercise produces same acute effects as conventional training. Methods: Nintendo® Wii was chosen stimulus for this study. Participants should conduct a physical training session under Exergames Training (ET) and Conventional (CT). Both conditions use two aerobic exercises six strength exercises, which were always performed in sequence. g...

In this paper we show that the effects of transgenic coreceptor expression on thymocyte development depend on the onset of transgene expression. Thus, a CD8 transgene expressed on CD44+CD25+ (DN2) and CD44-CD25+ (DN3) cells causes a partial block at the stage when TCRbeta selection takes place and diminishes expansion at the subsequent developmental stages, resulting in increased DN3 and marked...

Abstract Introduction Parkinson’s (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons in substantia nigra. It has motor and non-motor symptoms which directly related to these people’s decreased autonomy quality life. Aquatic physical therapy (APT) non-drug treatment option that resource complement functional rehabilitation and/or prevention. Objective To analyz...

BACKGROUND CD4+/CD8+ double positive (DP) T cells have been described in healthy individuals as well as in patients with autoimmune and chronic infectious diseases. In chronic viral infections, this cell subset has effector memory phenotype and displays antigen specificity. No previous studies of double positive T cells in parasite infections have been carried out. METHODOLOGY/PRINCIPAL FINDI...

Both physiological and psychological stress cause thymic atrophy via glucocorticoïd (GC)-dependent apoptosis of double-positive (DP) thymocytes. Given the pervasiveness of stress, GC-induced thymic atrophy is arguably the most common type of acquired immunodeficiency. We recently reported that interleukin-21 (IL-21) has a unique ability to expand the small subset of DP thymocytes (CD69(+)) whic...
