Unveiling the Chemical Diversity of the Deep-Sea Sponge .

Sponges are at the forefront of marine natural product research. In the deep sea, extreme conditions have driven secondary metabolite pathway evolution such that we might expect deep-sea sponges to yield a broad range of unique natural products. Here, we investigate the chemodiversity of a deep-sea tetractinellid sponge, , collected from ~800 m depth in Irish waters.

Anverenes B⁻E, New Polyhalogenated Monoterpenes from the Antarctic Red Alga .

The subtidal red alga was collected from the Western Antarctic Peninsula during the 2011 and 2017 austral summers. Bulk collections from specific sites corresponded to chemogroups identified by Young et al. in 2013.

Anatomy and biomechanics of the lateral side of the knee.

The posterolateral corner (PLC) of the knee is a critical element for a functional lower extremity. It consists of an array of complex ligamentous and musculotendinous structures. The primary function of the PLC is to resist varus and external rotation and posterior translation of the tibia.

Field-side and prehospital management of the spine-injured athlete.

Rapid on-field diagnosis and early stabilization can help to optimize the outcomes of spinal injury, which can have devastating consequences. Several basic principles will guide the rescuer through this process. Preinjury planning should include appointing a team leader, assessing the athletes' equipment, acquiring appropriate equipment to facilitate stabilization, and establishing lines of communication to emergency medical services (EMS).
