Autotransplantation of spleen tissue has been done, in the past ten years, in children with schistosomiasis mansoni with bleeding varices. The purposes of this investigation were: (1) to study the morphology and function of the remnant spleen tissue; (2) to quantify the production of tuftsin; and (3) to assess the immune response to pneumococcal vaccine of these patients. Twenty three children,...

The authors extend the classical Cormack–Jolly–Seber mark-recapture model to account for both temporal and spatial movement through a series of markers (e.g., dams). Survival rates are modeled as a function of (possibly) unobserved travel times. Because of the complex nature of the likelihood, they use a Bayesian approach based on the complete data likelihood, and integrate the posterior throug...

Indo-Pacific humpback dolphins (Sousa chinensis) inhabiting Hong Kong waters are thought to be among the world's most anthropogenically impacted coastal delphinids. We have conducted a 5-year (2010-2014) photo-ID study and performed the first in this region comprehensive mark-recapture analysis applying a suite of open population models and robust design models. Cormack-Jolly-Seber (CJS) models...

Two novel research approaches were developed to facilitate controlled access to, and long-term monitoring of, juvenile Steller sea lions for periods longer than typically afforded by traditional fieldwork. The Transient Juvenile Steller sea lion Project at the Alaska SeaLife Center facilitated nutritional, physiological, and behavioral studies on the platform of temporary captivity. Temporarily...

S creening for gestational diabetes mellitus requires an oral glucose challenge test with a 50-g glucola beverage and venous blood sample after 1 h. A “positive screen” is defined as a venous blood glucose of either .130 mg/dL or 140 mg/dL (1,2), and the patient then undergoes a diagnostic fasting 3-h glucose tolerance test (GTT) with a 100-g glucola (1). However, up to 30% of pregnant women ca...

Radio tags, because of their high detectability, are often used in capture-recapture studies. A key assumption is that radio tags do not cease functioning during the study. Radio-tag failure before the end of a study can lead to underestimates of survival rates. We develop a model to incorporate secondary radio-tag failure data. This model was applied to chinook smolts (Oncorhynchus tshawytscha...

Five patients developed overwhelming infection as a result of congenital asplenia, which was previously unsuspected in all cases. Each illness followed a fulminant course resulting in death within 24 hours. They illustrate the respective roles of Haemophilus influenzae infection (n = 4) and adrenal haemorrhage (n = 4) in this condition. We suggest a management protocol for screening infants wit...
