Impacts of Black Soldier Fly () Larval Meal on Intestinal Histopathology and Microbiome Responses in Hybrid Grouper ( ♀ × ♂): A Comprehensive Analysis.

This study examined the diversity and responses of intestinal microbiota in hybrid grouper ( ♀ × ♂) fed diets with varying levels of fishmeal replaced by black soldier fly larvae (BSFL). The 10% BSFL substitution (BSFL10) group showed the highest levels of trypsin and amylase. Substituting fishmeal with 30% and 50% BSFL weakened the intestinal wall, resulting in vacuoles, sparse striatal boundaries, and fewer villi.

Hypermagnesemia- and Hyperphosphatemia-Associated Cardiac Arrest after Injection of a Novel Magnesium-Based Bone Cement in Spinal Surgery.

We report a case of pulseless electrical activity (PEA) associated with profound hypermagnesemia immediately after cementation of a novel magnesium-based cement in spine surgery. During T8 to T12 posterior instrumentation and decompression laminectomy for vertebral metastasis secondary to lung cancer, a 61-year-old Chinese woman developed sudden hypotension and went into PEA immediately after injection of a novel magnesium-based cement. Intraoperative fluoroscopic imaging did not show any notable cement extravasation.

Outcomes of massive transfusion recipients administered ABO-incompatible fresh frozen plasma.

Background: The provision of ABO-incompatible fresh frozen plasma (FFP) in massive transfusion (MT) has become accepted to conserve AB FFP stock. There is an evidence gap in non-trauma settings. We compare characteristics of patients who received ABO-compatible or ABO-incompatible FFP during an MT episode due to any cause of critical bleeding, and assess the impact of incompatible FFP transfusion on inhospital mortality.

Could Metamaterials be the Next Frontier of Catalysis?

Plasmonic catalysis, whereby either an optically resonating metal couples to a catalytic material or a catalytic metal particle achieves optical resonance, has been a mainstay of photo-catalysis research for the past few decades. However, a new field of metal-dielectric metamaterials, including plasmonic metamaterials, is emerging as the next frontier in catalysis research. With new optical behaviors that can be achieved by sub-wavelength structures, in either periodic or semi-periodic arrangements, metamaterials can overcome some of the limitations of conventional plasmonic catalysis.
