Tracheal mucous velocity measurements were made in 24 beagle dogs in five age groups, using a gamma camera to detect movement of instilled 99mTc-macroaggregated albumin. Age groups were defined as immature (9-10 mo), young adult (2.8-3.0 yr), middle aged (6.7-6.9 yr), mature (9.6-9.8 yr), and aged dogs (13.6-16.2 yr). Mean velocities were 3.6 +/- 0.4 (SE) mm/min in the immature dogs, 9.7 +/- 0....

Hearing loss accompanied with middle ear effusion was analyzed according to audiometric frequencies for different age group. Results for left and right ears were compared in/and between study and control group. Pure tone audiometry for bone and air conduction and tympanometry was performed in study group of ninety-eight children with conductive hearing loss and otitis media with effusion. Contr...

background lower gastrointestinal bleeding (lgib) in children has many different etiologies and is a serious problem that warrants careful diagnostic work-up. materials and methods 164 colonoscopies were done during one year for determining the etiologies of lgib in children who was referred to children's medical center hospital. analyses of results were based on age, sex, etiology and clinical...

the evaluation of immune status to measles among school children in south of tehran, blood samples were collected from 375 randomly selected school children of elementary schools, junior high schools and high schools. the measurement of measles antibody titer was made by haemagglutination inhibition test, with antibody titer > 1/4 considered as positive. among 375 school children, 6% of them we...

conclusions the vitamin d levels of children aged more than 2 years are lower than those of children aged less than 2 years. thus, prescribing vitamin d-containing supplements in children older than 2 years may be beneficial. results the final study consisted of 286 children, 140 males and 146 females, with a mean age of 4.46 ± 2.82 yr. of these, 218 (76.22%) children, with a mean age of 5.09 ±...

This study aimed to estimate the efficacy of inertial training in older women using the Inertial Training and Measurement System (ITMS), an original device. Forty-five active women age 53-74 yr performed inertial training with 2 different loads (0 or 5 kg) 3 times weekly for 4 wk. Training sessions consisted of exercises involving the shoulder muscles of the dominant and nondominant arms. The m...

Although tuberculosis involves every organ and has a wide range of clinical manifestation, however involvement of the thyroid gland is rare. We report a case of a 25-yr-old female with supraclavicular lymphadenitis that developed nodular swelling of the thyroid and had symptoms and sonographic features mimicking a nodule with a cystic component. The diagnosis was made by using fine needle aspir...

BACKGROUND Antibiotic use in infancy disrupts gut microflora during a critical period for immune system development. It is hypothesized that this could predispose to the development of allergic diseases. We investigated the associations of antibiotic use in the first 2 yr of life with the development of asthma, eczema or hay fever by age 7.5 yr in a longitudinal birth cohort. METHODS Subjects...

Prostate cancer is a heterogeneous disease. MiR-375 is a marker for prostate cancer progression, but its cellular function is not characterized. Here, we provide the first comprehensive investigation of miR-375 in prostate cancer. We show that miR-375 is enriched in prostate cancer compared to normal cells. Furthermore, miR-375 enhanced proliferation, migration and invasion in vitro and induced...
