lps-responsive beige-like anchor (lrba) deficiency is a disease which has recently been described in a group of patients with common variable immunodeficiency (cvid) in association with autoimmunity and/or inflammatory bowel disease (ibd)-like phenotype. we here describe a 10-year-old boy who experienced recurrent infections, mainly in the respiratory system, associated with thrombocytopenia an...

Influenza is an acute respiratory disease caused by the influenza A or B virus. It often occurs in outbreaks and epidemics worldwide, mainly during the winter season.

Exposure to chemical agents, both deliberate and accidental, over the past 100 years has resulted in the deaths of thousands and a significant number of casualties requiring hospitalization. The respiratory system is an important portal of entry into the human body for many of these agents, and pulmonary symptoms are a hallmark of many chemical exposures. The 4 major chemical warfare agents are...

background :despite the presence of many textile and dyeing plants in iran, we couldn’t find similar studies in this country. forthermore, considering progress in the dyeing process and engineering controls, assessment of respiratory system is important for these workers. the present study was performed to evaluate the respiratory system in dyeing workers.   methods : in a cross-sectional study...

background: proper analgesic agents should be used in combination with sedative agents. remifentanil is a synthetic narcotic/analgesic agent with a short duration effect and decreases the risk of apnea during recovery. bispectral index system (bis) is a new noninvasive technique for the evaluation of the depth of sedation. the aim of present clinical trial was to evaluate and compare the effi c...

in this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition petri nets. the mobile agent system contains two mobile agents called dca and una. it sends out agents to update antivirus on client computers in a network. each agent takes on a specified responsibility. first, dca roams through the network and check the last d...
