During fire emergencies, firefighters wear personal protective devices (PC) and a self-contained breathing apparatus (S.C.B.A.) to be protected from injuries. The purpose of this study was to investigate the differences of aerobic level in 197 firefighters (age: 34±7 yr; BMI: 24.4±2.3 kg.m-2), evaluated by a Queen's College Step field Test (QCST), performed with and without fire protective garm...
ABSTRACT We present the results of an extensive analysis optical, ultraviolet, X-ray, and γ-ray data collected from observations BL Lac objects prototype Lacertae carried out over a period nearly 13 yr, between 2008 August 2021 March. The source is characterized by strongly variable emission at all frequencies, often accompanied spectral changes. In band several prominent flares have been detec...
We followed up swimming performance times of 321 women and 319 men who participated in the US Masters Swimming Championships over a 12-yr period. All swimmers placed in the top 10 in their age group over 3 yr (mean = 5 yr). A random coefficients model for repeated measures was used to derive a line of best fit from a group of regression lines for each subject. Both 50- and 1,500-m swimming perf...
On the basis of cross-sectional data, we previously reported that the absolute, but not the relative (%), rate of decline in maximal oxygen consumption (VO(2 max)) with age is greater in endurance-trained compared with healthy sedentary women. We tested this hypothesis by using a longitudinal approach. Eight sedentary (63 +/- 2 yr at follow-up) and 16 endurance-trained (57 +/- 2) women were ree...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...

BACKGROUND Age-related losses of muscle mass, strength, and function (sarcopenia) pose significant threats to physical performance, independence, and quality of life. Nutritional supplementation could positively influence aspects of sarcopenia and thereby prevent mobility disability. OBJECTIVE To test the hypothesis that a specific oral nutritional supplement can result in improvements in mea...
In this study, we report a Japanese boy with testotoxicosis due to a heterozygous mutation [p. A572V] in the LH/CGR gene, who was the first boy treated with a third-generation aromatase inhibitor (AI) and reached his adult height in Japan. He showed accelerated growth and rapid penile growth from 3 yr of age and was diagnosed as having testotoxicosis. Combined treatment with anastrozole and spi...
abstract: Hypospadias is one of the most common congenital malformations. Few studies have explored the association of age at time of surgery and the occurrence of complications after hypospadias repair. We undertook this study to determine whether age at hypospadias repair is a risk factor for development of complications. Hypospadias is one of the most common congenital malformations. Few stu...
