Study on the relationship between muscle fatigue and motion sickness responses in different sitting postures under ship rocking conditions.

In a ship rocking environment, muscle activity in different sitting postures may impact passenger balance and stability, thereby aggravating or alleviating symptoms of motion sickness. This study aims to explore the relationship between motion sickness induced by ship rolling and muscle activity in various sitting postures, with the goal of informing the optimization of ship seat designs to enhance passenger comfort. The research focuses on the angle of backrest inclination and head-neck position as key variables.

Diagnostic Value of CT Window Technique for Primary Omentum Infarction.

Objective: The diagnostic value of CT window width technique in primary omentum infarction was evaluated by this study.

Methods: The abdominal CT data of 32 patients with clinically diagnosed abdominal omentum infarction were retrospectively selected and analyzed. The fixed window position was 50 HU, and the window width was 135 HU, 250 HU (abdomen), 350 HU (mediastinum), and 500 HU, respectively.

Experimental study of the effect on bone metabolism and bone histomorphometry of osteoporosis rats with birdpecking and revolving moxibustion on twelve back-shu points.

The aim of the study was to explore the effect of birdpecking and revolving moxibustion on twelve back shenshu points on the bone metabolism and bone histomorphometry of osteoporosis rats. The 50 female rats of 8 months old that did not pregnant were collected and randomly divided into sham-operation group, model group, moxibustion group, moxibustion and estrogen group, and estrogen group. All the rats, except for the rats in the sham-operation group, received ovarian surgery to establish the models.

Energy metabolism and survival of liver grafts from non-heart-beating donor rats with warm ischemia injury.

Background: The shortage of donor livers is a critical limiting factor for the use of liver transplantation in treatment of end-stage liver diseases. Organs from non-heart-beating donors seem to be an effective option to alleviate this problem. Warm ischemia injury, however, directly influences the grafts' activity and functional recovery after operation.
