AIM The aim of this study was to investigate inflammatory and respiratory responses to welding fume exposure in patients with suspected occupational asthma. METHODS Sixteen patients referred to the Finnish Institute of Occupational Health underwent mild steel (MS) and stainless steel (SS) welding challenge tests, due to suspicion of OA. Platelet count, leucocytes and their differential count,...

Background: The Centers for Disease Control and Prevention estimates that 30 million Americans are living with diabetes and by 2050, 1 out of 3 U.S. adults could develop diabetes. Current screening and diagnostic methods for diabetes mellitus include the oral glucose tolerance test (OGTT), hemoglobin A1c (HbA1c), and fasting plasma glucose (FPG) levels, but each test when used alone will miss a...

Eleven hundred and nine iron mine workers aged 35 to 55 with normal chest radiographs were submitted to a pulmonary examination consisting of a questionnaire, a clinical examination, and pulmonary function testing including an acetylcholine challenge test. A positive response (decrease of FEV1 of more than 10%) was observed in 210 subjects (Ace+). The remaining 899 had a negative response (Ace-...

A 20-year-old white female nonsmoker presented to the pulmonary function laboratory for a methacholine challenge test. The patient denied wheezing, dyspnea, cough, or chest tightness. In fact, she competes in collegiate basketball and softball without respiratory complaints. She stated that her primary care physician wanted to “screen her for asthma,” because her father is asthmatic. Her medica...

Powering VLSI die up to 200A in sort test, especially for a structural test system, requires a High Current Device Power Supply (HCDPS) able to provide this amount of current within a very fast response. A new HCDPS structure is implemented to overcome the prober interface constraints and sustain applied voltage during die current transitions with high dI/dt.

BACKGROUND Central serotonergic mechanisms appear to participate in the pathogenesis of recurrent neurally mediated syncope. The aim of the study was to investigate the responsiveness of the central serotonergic system by measuring the prolactin and cortisol responses to intravenous administration of the serotonin reuptake inhibitor clomipramine. METHODS AND RESULTS Twenty subjects free of an...

Diagnosis of food allergy should be based on the observation of allergic symptoms after intake of the suspected food. The oral food challenge test (OFC) is the most reliable clinical procedure for diagnosing food allergy. The OFC is also applied for the diagnosis of tolerance of food allergy. The Japanese Society of Pediatric Allergy and Clinical Immunology issued the 'Japanese Pediatric Guidel...

BACKGROUND Oral food challenges (OFCs) are performed for diagnosis of a food allergy in cases where the allergy is not supported by patient history, or when a newly developed tolerance level needs to be established. OBJECTIVE We aimed to investigate the prevalence and severity of reactions during OFCs in preschool children. METHODS A retrospective study was conducted on children younger tha...

Background The prevalence of Food Allergy (FA) is increasing and the correct diagnosis is mandatory among patients with adverse reactions to foods. The oral food challenge tests (OFCT) remain the better tests for FA diagnosis and its usage is essential to avoid misdiagnosis. As severe reactions may occur, staff must be prepared to manage lifethreatening situations. The aim of this study was to ...

C ryptographic circuits need special test infrastructure due to the concern of security involved. Normal design for testability methods, such as scan chains, as applied to most ASICs cannot be applied directly to Cryptographic chips. These methods, though providing the highest testability, open backdoors or side-channels for attackers, to extract secret keys or Intellectual Property information...
