Filter by:The objective of this study is to correlate various diagnostic measurements taken during an escalating dose oral food challenge to the subject's response. This study will investigate whether non invasive objective biomarkers can indicate a positive response to an escalating dose OFC before a systemic reaction occurs.
Obesity is a chronic disease of multifactorial etiology that develops from the interaction of the influence of nutritive , metabolic , cellular and molecular psychological factors. Tadalafil is Is a drug inhibiting the enzyme phosphodiesterase-5 (PDE-5), responsible for inactivating the vasodilator nitric oxide. USING paragraph was mainly treat erectile dysfunction, and recently approved for the treatment of pulmonary hypertension , it is innovative because of its longer life means, provides efficacy after 36 hours and the highest selectivity. The aim of this study is to evaluate the effect of tadalafil on insulin sensitivity and insulin secretion in obese men. The investigators hypothesis is that the administration of tadalafil improve the insulin sensitivity and insulin secretion in obese men.
Currently FDA does not accept pharmacokinetic studies to show bioequivalence of locally-acting nasal suspension formulations. However, bioequivalence is defined as the absence of significant differences in pharmacokinetics of therapeutically equivalent drug products compared to the matching originally invented drug formulation. These there-called "generic drugs" are then interchangeable. Drug companies have to show that their generic version has the same active ingredient, the same label, is intended to be used for the same conditions or diseases and works at the same rate in the body. The aim of the study is to determine if pharmacokinetics is sensitive to differences in the particle size distribution of two different nasal suspension formulations of mometasone furoate during charcoal block. The result from this study will aid the FDA in finding methods to ensure that generic products are the same as the trade name drugs.
The purpose of this study is to determine the effect of gemcabene on insulin sensitivity as defined by average glucose disposal rate.
This study will evaluate the effect of circadian misalignment on insulin sensitivity in healthy lean subjects in a randomized cross-over design. Subjects will be admitted to the research facility for two study periods of 3 and 3.5 days. In one of the study periods, the behavioral cycle will be shifted by 12 hours. Insulin sensitivity will be measured with a hyperinsulinemic euglycemic clamp.
This is a randomized, parallel, single center, double masked, vehicle controlled study. The purpose of this study is to determine the activity and safety of NS2 in patients with grass, tree or ragweed-pollen induced seasonal allergic conjunctivitis . Subjects will be randomized 1:1 to receive multiple doses of NS2 Ophthalmic Drops (0.5%) or NS2 Ophthalmic Drops Vehicle (0.0%). Free aldehydes are thought to be related to inflammatory conditions such as allergic conjunctivitis. NS2, a small molecule aldehyde trap, is being evaluated to determine whether it may decrease inflammation by lowering aldehyde levels.
Study objectives Primary objective: This study wants to evaluate the safety of a latex safe protocol as proposed by the Australasian Society of Clinical Immunology and Allergy. In other words,the investigators hope to demonstrate that patients with known latex allergy or latex sensitisation can be treated safely in operating theatres without special requirements towards scheduling provided that all powdered latex gloves are removed from the OR environment( preparation rooms, theatres, recovery room and surroundings). In contrast, earlier guidelines require the theatre to be left unused during at least 3 hours before a patient with suspected latex allergy can be operated on in this theatre. Secondary objectives: - The investigators want to evaluate to what extend patients who report a latex allergy show risk factors of latex allergy. - To investigate to what extend latex allergy was proven by laboratory testing or skin testing in patients who report a latex allergy. - Type of latex allergic reaction when patients report a latex allergy. - The level of satisfaction of surgeons and OR scheduling staff with the new latex safe protocol and with the switching to powder free latex gloves.
This study of the tolerance and acceptability of an amino acid based feed will assess gastrointestinal (GI) tolerance, product intake and acceptability in relation to taste, smell, texture in 20 patients between 1-10 years currently using or requiring an amino acid based feed for the dietary management of Cows' Milk Allergy and food-allergy-associated conditions, over 4 weeks.
Skin prick test (SPT) was used for diagnostic test for type 1 hypersensitivity. The efficacy and safety of SPT were proved. The positive control of SPT is histamine. In Thailand, the most common concentration of histamine for SPT is 10 mg/ml. However, in some practice they use other concentration (1, 2.5 mg/ml). This study will find the proper concentration of histamine for positive control use in SPT.
The prevalence of Allergic rhinitis(AR) and asthma was increased world wide. In 1998, ISAAC found that prevalence of AR and asthma inThailand was in moderately high group. Tests for immediated reaction SPT and spIgE, were used for evaluated sensitization of allergen in patient. They guided the investigators for proper management as well as patient education. Clinician will use the result for choose allergen in case that might need immunotherapy. SPT is safe and more economic for patient. Specific IgE has an advantage in patient who cannot withhold antihistamine prior SPT. In United state had a trial of result between SPT and spIgE for cockroach, cat, house dust mite and mold. It showed the correlation between two tests. In Thailand, the investigators haven't had data about it yet.
