SERIAL HEALTH ASSESSMENT WITH STANDARDIZED EXTERNAL SCORING AND HEMOLYMPH EVALUATION IN THE AMERICAN HORSESHOE CRAB ().

Serial health assessment of a managed population of American horseshoe crabs (HSC; ) was performed. Twenty HSC were examined once a month for 7 mon; this included a physical exam with a standardized scoring sheet, HR, morphometrics, and hemolymph evaluation with hemocyte count, copper concentration, and biochemistry panel. The HSC in this population had varying levels of external lesions at enrollment.

Polycystic ovarian disease in aquarium-managed cownose rays Rhinoptera bonasus.

Significant knowledge gaps remain in our understanding of the reproductive physiology and diseases of elasmobranchs. The objective of this work is to describe the clinical, imaging, and pathologic findings associated with polycystic ovaries in cownose rays housed in public aquariums. Ten adult female cownose rays Rhinoptera bonasus housed in 4 public aquariums presented with variable nonspecific (lethargy, anorexia, cutaneous discoloration) or no clinical signs.

Ocular and Systemic Risk Factors for Disease Worsening Among Patients with NPDR: Post Hoc Analysis of the PANORAMA Trial.

Purpose: Identify baseline systemic and ocular characteristics associated with nonproliferative diabetic retinopathy (NPDR) worsening, and the impact of intravitreal aflibercept injection (IAI) on these associations.

Design: Post hoc analysis of PANORAMA.

Participants: Patients with moderately severe to severe NPDR enrolled in the prospective PANORAMA phase 3 trial.

Nitrogen accountancy in space agriculture.

Food production and pharmaceutical synthesis are posited as essential biotechnologies for facilitating human exploration beyond Earth. These technologies not only offer critical green space and food agency to astronauts but also promise to minimize mass and volume requirements through scalable, modular agriculture within closed-loop systems, offering an advantage over traditional bring-along strategies. Despite these benefits, the prevalent model for evaluating such systems exhibits significant limitations.
