On the basis of a study of the literature and a description of the parachute jump, the injury producing factors of civil parachuting is described. The majority of injury happens during landing; the assuming of a correct "prepare to land attitude" and the execution of a good parachute landing fall may prevent a great part of the injuries to the spine and the lower extremities. The factors mentioned are often correlated to ignorance, inexperience or to willful neglect of current regulations. A revision of the education of student parachuters and instructors in order to meet the same quality demands in all parachuting centres is proposed. Safer parachutes and a simplification of the parachute landing fall may also reduce the incidence of casualties.

Introduction: In England, increasing numbers of young people seek help from emergency healthcare services, such as ambulances and emergency departments, after they self-harm. One contributing factor is a lack of meaningful and available community-based alternative sources of support for self-harm. It is not clear what helps young people in this context, how or why.

Dynamic variables contribute to understand the mechanics of pedalling and can assist with injury prevention. Measuring pedal forces and joint moments and powers has a high cost, which can be mitigated by using trained artificial neural networks (ANN) to predict forces from kinematics. Thus, this study aimed at training and validating recurrent ANN to predict 3D pedal forces, lower limb joint moments and powers from lower limb kinematics.

Introduction: Doppler ultrasound is used to detect inert gas bubbles in the body following decompression from dives. Two sites may be monitored, the precordial (PC) and subclavian (SC) positions. PC is the predominant site, allowing observation of bubbles returning from the entire body.

Background: Despite advancements in bovine embryos cryopreservation techniques, challenges remain, warranting further investigation into their impact on embryo morphology and viability so that outcomes can be improved.
Objective: To analyze, through transmission electron microscopy (TEM), in vitro-produced bovine embryos vitrified using the Cryotop method.
Materials And Methods: Groups of embryos were transferred to a stabilization solution (SS) containing 7.
