Infection of the type II feline infectious peritonitis virus (FIPV) strain 79-1146 to primary feline alveolar macrophages and human monocyte cell line U937 was enhanced by the sera of cats experimentally infected with the 79-1146 strain, but not those of cats infected with KU-2 or UCD-1 strain of type I FIPV. The experiments using sera of cats with feline infectious peritonitis (FIP) and of cat...

We analyzed the endogenous requirement for Cerberus in Xenopus head development. 'Knockdown' of Cerberus function by antisense morpholino oligonucleotides did not impair head formation in the embryo. In contrast, targeted increase of BMP, Nodal and Wnt signaling in the anterior dorsal-endoderm (ADE) resulted in synergistic loss of anterior head structures, without affecting more posterior axial...

The use of embryonic stem cell (ESC) differentiation to generate functional hepatic or pancreatic progenitors and as a tool for developmental biology is limited by an inability to isolate in vitro equivalents of regionally specified anterior definitive endoderm (ADE). To address this, we devised a strategy using a fluorescent reporter gene under the transcriptional control of the anterior endod...

BACKGROUND Hepatocellular carcinoma (HCC) accounts for major cancer-related deaths despite current advanced therapies. Treatment and prognosis of HCC is better in patients with preserved liver function. Many natural products including ajwa dates (Phoenix dactylifera L.), are claimed to have hepatoprotective and HCC inhibitory effects, but most lack scientific validation. To prove our hypothesis...

BACKGROUND While the association between a drug and an adverse event (ADE) is generally detected at the level of individual drugs, ADEs are often discussed at the class level, i.e., at the level of pharmacologic classes (e.g., in drug labels). We propose two approaches, one visual and one computational, to exploring the contribution of individual drugs to the class signal. METHODS Having esta...

PURPOSE Physicians in the United States report fewer than 1% of adverse drug events (ADEs) to the Food and Drug Administration (FDA), but frequently document ADEs within electronic health records (EHRs). We developed and implemented a generalizable, scalable EHR-based system to automatically send electronic ADE reports to the FDA in real-time. METHODS Proof-of-concept study involving 26 clini...

A fractional advection-dispersion equation (ADE) is a generalization of the classical ADE in which the second-order derivative is replaced with a fractional-order derivative. In contrast to the classical ADE, the fractional ADE has solutions that resemble the highly skewed and heavy-tailed breakthrough curves observed in field and laboratory studies. These solutions, known as alpha-stable distr...
