Patterning of the Drosophila embryonic termini is achieved by localized activation of the Torso receptor by the growth factor Trunk. Governing this event is the perforin-like protein Torso-like, which is localized to the extracellular space at the embryo poles and has long been proposed to control localized proteolytic activation of Trunk. However, a protease involved in terminal patterning rem...

Figure 1 Kneeling trunk rotation (a) start position (b) final position. Sports such as tennis, golf, baseball, and hockey each involve a tremendous amount of trunk rotation. It is not just striking sports, but also throwing, kicking, running, swimming, skiing, etcwhichall require yourbody to rotate throughyour core. In order to transmit forces from your bigger, stronger leg muscles to your arms...

queueing model. We define a new concept of trunk as a group of voice traffic with identical destination and DSCP. It is assumed that at least one trunk should be established between the ingress router and corresponding egress router. Each trunk has a different voice traffic arrival rate and mean service timc. We assume that there are P types of queues. In a queue of typc lc (k = I, 2, ..., P), ...

The prevalence of low back disorders is dramatically high in viticulture. Field measurements that objectively quantify work exposure can provide information on the relationship between the adopted trunk postures and low back pain. The purposes of the present study were three-fold (1) to carry out a kinematics analysis of vineyard-workers' pruning activity by extracting the duration of bending a...

Difficulty in transferring, the ability to rise in and out of a bed and chair, is a common problem in older adults, particularly those residing in skilled nursing facilities. Focusing on one aspect of transferring, rising from supine to sitting position, we devised a set of bed mobility tasks to test key arm, leg, and trunk movements that likely contribute to successful rising from bed. Healthy...

The aim of this study was to determine the accuracy trunk displacement extracted from an inertial motion capture system (IMC) compared to an optical motion capture system (OMC). Participants walked overground while trunk displacement data from IMC and OMC were simultaneously recorded. The resultant trunk speed from both systems during walking and brief standing periods were compared. No differe...

An effective strategy for walking over rough terrain, flat plane, and wreckage includes transitioning from quadrupedal to bipedal locomotion. In this study, we designed a trunk mechanism that provides successful posture transition from quadrupedalism to bipedalism. The proposed trunk mechanism imitates the human trunk with redundant joints and elastic muscles supporting the trunk. The simulatio...

Social, psychological, and physiological studies have provided evidence indicating that laughter imposes an increased demand on trunk muscles. It was the aim of this study to quantify the activation of trunk muscles during laughter yoga in comparison with crunch and back lifting exercises regarding the mean trunk muscle activity. Muscular activity during laughter yoga exercises was measured by ...

[Purpose] To investigate the effects of Pilates breathing on trunk muscle activation. [Subjects and Methods] Twenty-eight healthy female adults were selected for this study. Participants' trunk muscle activations were measured while they performed curl-ups, chest-head lifts, and lifting tasks. Pilates breathing trainings were performed for 60 minutes per each session, 3 times per week for 2 wee...

OBJECTIVE To examine the effects of trunk exercises performed using the physio ball as against the plinth, on trunk control and functional balance in patients with acute stroke. DESIGN An observer-blinded pilot randomized controlled trial. SUBJECTS Thirty patients with acute stroke (mean post-stroke duration 12 (95% confidence interval (CI) 2-34) days) who had the first onset of unilateral ...
