Sleep tendency (latency to sleep onset) was examined during extended waking in prepubertal and mature adolescents to determine whether sleep pressure is lower near bedtime in the latter group. Participants were nine prepubertal (pubertal stage Tanner 1, mean age 11.1 years, SD+/-1.3 years, five males) and 11 pubertally mature adolescents (Tanner 5, 13.9+/-1.2 years, three males). They spent 10 ...

The dynamic relationship between the predator and the prey has long been and will continue to be one of the dominant themes in population dynamics due to its universal existence and importance in nature 1 . In order to precisely describe the real ecological interactions between species such asmite and spidermite, lynx and hare, and sparrow and sparrow hawk, described by Tanner 2 and Wollkind et...

  A new technique in spring ligament reconstruction using medial half of posterior tibial tendon is demonstrated as a means of supporting the arch. In addition a new concept of double bundle PTT reconstruction based on anatomical attachments of original PTT is presented with the goal of obtaining the full function of PTT.

Introduction: Photothermal therapy (PTT) is a nanotechnology-assisted cancer hyperthermia approach in which the interaction between laser light and plasmonic nanoparticles generates a localized heating for thermoablation of the tumor. Recent efforts in the area of PTT follow two important aims: (i) exploitation of targeting strategies for preferential accumulation of plasmonic ...

The 3G era brings new opportunities to telecommunications industry. This article introduces current situation of using network technology in digital library, in the 3G network, PTT has its own advantages so that it is feasible to be used in digital library. We highlight instance about digital library using PTT, and then solve the issue of context-aware transformation and use SIP-based system ar...

The article presents preliminary data from a prospective investigation in a sample of healthy 14-17-year-old students from a technical school in Sao Paulo, Brazil. Ninety-six Tanner stage 5 and thirty-one Tanner stage 4 adolescents were evaluated: testicular volume was measured using a Prader orchidometer, and semen analysis was performed according to standard procedures. Median testicular volu...

INTRODUCTION Determine body composition changes in adiposity can assess an individual. OBJECTIVE The objective of this study was to evaluate total body fat percentage based on two and four compartment models in obese Chilean school children, adjusting for differences in sex and puberty status. METHODS Sixty-one obese school children (33 boys and 28 girls) between 8 and 13 years of age were ...

<p style='text-indent:20px;'>We identify two new traveling waves of the Holling-Tanner model with weak diffusion. One connects constant states; at one them, is undefined. The other a state to periodic wave train. We exploit multi-scale structure in diffusion limit. Our analysis uses geometric singular perturbation theory, compactification and blow-up method.</p>

Perinatal testicular torsion (PTT) is a rare entity. The management of PTT is controversial, due to the low viability of the testis and the possibility of bilateral torsion. This is a review of our experience with six cases of PTT, highlighting diagnostic and therapeutic difficulties of this condition.

Different components of the autonomic nervous system may be affected by different disorders to varying degrees. The aim of this study is to report first experiences with a new device (FAN(R), Schwarzer, Germany) which measures heart rate variability (HRV), sympathetic skin responses (SSR) and the pulse wave transit time (PTT). We examined 190 healthy volunteers (102 men, 88 women) and in 89 sub...
