Studies on human postmortem material report lower brain weights in older than in younger cohorts, whereas there is no apparent change with age in the rhesus monkey. In view of these contrasting results, we examined the pattern of brain weight across the life span in the chimpanzee, one of the closest biological relatives of humans. To place the study in(More)
Cross-sectional studies on adult human autopsy material have shown that younger cohorts have heavier brains than older groups. We sought to determine whether a similar pattern is present in the rhesus monkey, a species that serves as a useful model of human brain and cognitive aging. Data were obtained from necropsies of 399 rhesus monkeys (180 females; 219(More)
T lymphocytes are found within brains infected with human immunodeficiency virus (HIV) or simian immunodeficiency virus (SIV) where they are a minor, but consistently identified, population. However, little analysis of their phenotypes has been done, and questions concerning whether or not they are viral antigen specific has not been thoroughly examined. We(More)
Although magnetic resonance imaging has been used to examine the brain of domestic ruminants, detailed information relating the precise anatomical features in these species is lacking. In this study the brain structures of calves (Bos taurus domesticus), sheep (Ovis aries), goats (Capra hircus) and a mesaticephalic dog (Canis lupis familiaris) were examined(More)
SSBP proteins bind and stabilize transcriptional cofactor LIM domain-binding protein1 (LDB1) from proteosomal degradation to promote tissue-specific transcription through an evolutionarily conserved pathway. The human SSBP2 gene was isolated as a candidate tumor suppressor from a critical region of loss in chromosome 5q14.1. By gene targeting, we show(More)
BACKGROUND Dynamic contrast-enhanced MRI (DCE-MRI) biomarkers have proven utility in tumors in evaluating microvascular perfusion and permeability, but it is unclear whether measurements made in different centers are comparable due to methodological differences. PURPOSE To evaluate how commonly utilized analytical methods for DCE-MRI biomarkers affect(More)
We previously demonstrated that CBF activity is needed for cell proliferation and early embryonic development. To examine the in vivo function of CBF in differentiated hepatocytes, we conditionally deleted CBF-B in hepatocytes after birth. Deletion of CBF-B resulted in progressive liver injury and severe hepatocellular degeneration 4 weeks after birth.(More)
BACKGROUND To develop and evaluate the feasibility of emerging interventions, animal models with accurate anatomical environment are required. OBJECTIVES We aimed to establish a clinically relevant colorectal tumor model with canine transmissible venereal tumor (CTVT) utilizing endoscopic ultrasound (EUS) imaging guidance. DESIGN Survival study using a(More)
Neurological cases, especially in foals, are rare in the daily practical work. The most common causes are traumata and infectious diseases of the central nervous system (CNS). This case report provides further insights into the wide spectrum of possible neuropathological lesions by detailing a complex malformation with unilateral neurological signs that(More)
