Acute psychological and physiological benefits of exercising with virtual reality.

Exercise is a powerful tool for disease prevention and rehabilitation. Commercially available virtual reality (VR) devices and apps offer an immersive platform to gamify exercise and potentially enhance physiological and psychological benefits. However, no work has compared immersive exercise to closely matched 2D screen-based equivalents with the same visual and auditory stimuli.

Traumatic Tension Pneumothorax: A Tale of Two Pathologies.

Pneumothorax resulting from injury is a common phenomenon in both civilian and military trauma. A pneumothorax or simple pneumothorax is defined as air in the pleural space. A tension pneumothorax can evolve from a simple pneumothorax if there is a continued air leak from the lung without mechanism for egress.

Biopsychosocial Health Considerations for Astronauts in Long-Duration Spaceflight: A Narrative Review.

Long-duration spaceflights beyond low-Earth orbit, including missions to the Moon and Mars, pose significant health risks. Although biomedical approaches commonly appear in the literature, considering psychological and social factors alongside physiologic health offers a more holistic approach to astronaut care. Integrating the biopsychosocial (BPS) framework into medical planning addresses complex spaceflight challenges and aids in developing mitigation strategies.

Direct whole-cell patch-clamp recordings from small boutons in rodent primary neocortical neuron cultures.

Direct electrical recordings from conventional boutons in the mammalian central nervous system have proven challenging due to their small size. Here, we provide a protocol for direct whole-cell patch-clamp recordings from small presynaptic boutons of primary dissociated cultured neurons of the rodent neocortex. We describe steps to prepare primary neocortical cultures and recording pipettes, followed by identifying boutons and establishing a whole-cell bouton recording.

Cric in the Dark: Surgical Cricothyrotomy in Low Light Tactical Environments.

Background: Surgical cricothyrotomy (SC) is a difficult procedure with high failure rates in the battlefield environment. The difficulty of this procedure is compounded in a low-light tactical environment in which white light cannot be used. This study compared the use of red-green (RG) light and red (R) light in the performance of SC in a low-light environment.
