Futuristic perspectives: novel MCS devices.

Treatment of heart failure needs a firm understanding of anatomy and physiology of the circulatory system and the heart. Ancient India takes credit for the "modern concepts" of human circulation. This short review encompasses futuristic perspectives on mechanical circulatory devices (MCS).

PRELIMINARY EVALUATION OF SYMMETRIC DIMETHYLARGININE AS A BIOMARKER OF RENAL INSUFFICIENCY IN WILD AND REHABILITATED FLORIDA MANATEES ().

Currently, there are limited antemortem tests available to evaluate renal function in Florida manatees (). Although few reports of renal pathology in manatees exist in the veterinary literature, debilitated animals that present to rehabilitation centers are frequently dehydrated, may have sustained renal trauma secondary to watercraft injury, and may experience ischemic events related to coagulation disorders leading to renal compromise. Clinicians remain limited to the analysis of blood urea nitrogen, creatinine levels, and urinalysis (if urine is obtained) to determine the extent of renal insufficiency, which may not accurately reflect renal function.

Cytochemical staining of leukocytes and platelets in the Florida manatee (): identification of a bilobed monocyte similar to other members of the .

Manatees (Antillean-, Amazonian, and African-) and dugongs belong to the Order , and when combined with elephants and rock hyraxes, form the . A bilobed mononuclear cell has previously been identified in elephants and rock hyraxes, but not in manatees and dugongs, with cytochemical staining identifying these cells as bilobed monocytes in elephants. The objective of this study was to characterize leukocytes (white blood cells, WBC) and platelets in blood films of Florida manatees (;  = 8) using one routine hematological (Wright-Giemsa) and eight cytochemical stains: alkaline phosphatase (ALP), α-naphthyl butyrate esterase (ANBE), chloroacetate esterase (CAE), Luna, myeloperoxidase (MPx), periodic acid-Schiff (PAS), Sudan black B (SBB), and toluidine blue (TB).

Resonantly Coupled High-Efficiency Sensors for Assessment of Ventricular Chamber Size for Autonomous Control of Left Ventricular Assist Device.

Current left ventricular assist devices (LVADs) are set to a fixed rpm and are unable to adjust to physiological demands irrespective of preload or afterload. Autonomous control of LVADs has the potential to reduce septal shift, preserve right ventricle function, and meet physiological demands. A highly innovative resonantly coupled regimen is presented which can achieve this goal.

Diet composition of the African manatee: Spatial and temporal variation within the Sanaga River Watershed, Cameroon.

The present study aimed to investigate the diet of African manatees in Cameroon to better inform conservation decisions within protected areas. A large knowledge gap on diet and seasonal changes in forage availability limits the ability to develop informed local management plans for the African manatee in much of its range. This research took place in the Sanaga River Watershed, which includes two protected areas in the Littoral Region of Cameroon: the Douala-Edea National Park and the Lake Ossa Wildlife Reserve.
