BACKGROUND Emphysema is defined as the abnormal enlargement of airspaces distal to the terminal bronchiole, but the limits of normality of airspace size have never been defined. The aims of the study were to examine the effects of age and sex on airspace size in non-smokers and to define the limits of normal airspace size. METHODS Airspace size was measured in terms of airspace wall surface a...
هدف این پژوهش به کارگیری skew-normal (sn) markov-switching(ms) garch جهت لحاظ نمودن چولگی در توزیع سریهای زمانی مالی است. انگیزه اصلی بیان این مدل آن است که روش متداول برای در نظر گرفتن عدم تقارن در مدل های normal(n) ms garch یعنی اضافه نمودن میانگین رژیم ها به مدل، منجر به ایجاد بازده های خود همبسته می گردد که امری نامطلوب است. جهت یک مقایسه کامل ، تمامی حالات ممکن مدل های sn ms garch و n ms g...
four patients were studied for intercostals nerve blockade in cholecystectomy. all of the patients were poor risks (class 4) and received premedication before the procedure. intercostals nerve blockade (icnb) of the 7th and 10th thoracic nerves on the right side was performed with lidocaine 1% plus adrenaline 5 ml. at each segment, t7-t10 (a total dose of 20 ml). ventilation was controlled usin...
BACKGROUND Echocardiographic upper normal limits of both main pulmonary artery (MPA) diameters (MPA-d) and ratio of MPA to aortic root diameter (MPA-r) are not defined in healthy adults. Accordingly, frequency of MPA dilatation based on echocardiography remains to be assessed in adults with Marfan syndrome (MFS). METHODS We enrolled 123 normal adults (72 men, 52 women aged 42 ± 14 years) and ...
A 25-year-old lady G2P1L1A0 presented to the emergency room with four-day history of lower abdominal pain and six weeks’ amenorrhea. Her sexual and past medical history was unremarkable. Her previous delivery was by cesarean section. The vital signs were within normal limits. Physical examination was also within normal limits except for mildto-moderate lower abdominal tenderness on palpation wi...
Indian J Dermatol Venereol Leprol | September-October 2009 | Vol 75 | Issue 5 of all routine investigations were within normal limits. Results of HIV antibody test and Mantoux test were negative. Collagen profile was within normal limits. Histological examination of the tissue from the lesion on the left side of nose showed multiple follicular and parakeratotic invaginations in the epidermis, a...
PURPOSE To compare intersubject variability and normal limits of threshold values between the new Swedish interactive test algorithm short wavelength automated perimetry (SITA SWAP) and the older Full Threshold SWAP programs (Carl Zeiss Meditec, Dublin, CA). METHODS Normal reduction of differential light sensitivity with age, age-corrected thresholds, intersubject variability, and normal limi...
The valve system in the mouth piece of two spacer devices was analysed. Pressures required to open and close the non-rebreathing valve were very low (less than 0.1 kPa). Inspiratory flow requirements were within physiological limits for infants' normal tidal breathing. Expiratory flow requirements varied significantly, and the flow required to prevent rebreathing from the chamber may exceed the...
