Mechanical characteristics of bilayer lipid membranes (BLM) composed of dimyristoylphosphatidylcholine (DMPC) and cholesterol in the gel and liquid crystalline state were studied by measuring the modulus of elasticity in direction perpendicular to the BLM plane, E perpendicular. The value of E perpendicular varied nonmonotonically with the cholesterol concentration, with a maximum around c = 50...

A biological experiment of six weeks duration, followed by several laboratory investigations were carried out to study the effect of designer layer mash (DLM) containing full fat flaxseed, oil rich sardine fish, Holy Basil leaf meal (BLM), vitamin E and Organic selenium (Sel-plex), on haematology of layers. Both designer diet and BLM had significant effect on haematology of layers. They also ex...

The adenovirus (Ad) E1b55K and E4orf6 gene products assemble an E3 ubiquitin ligase complex that promotes degradation of cellular proteins. Among the known substrates are p53 and the Mre11-Rad50-Nbs1 (MRN) complex. Since members of the RecQ helicase family function together with MRN in genome maintenance, we investigated whether adenovirus affects RecQ proteins. We show that Bloom helicase (BLM...

The role of interleukin (IL)-18 in the protection from interstitial pneumonia and pulmonary fibrosis induced by bleomycin (BLM) was investigated by comparing the severity of BLM-induced lung injuries between wild-type and C57BL/6 mice with a targeted knockout mutation of the IL-18 gene (IL-18-/- mice). IL-18-/- mice showed much worse lung injuries than wild-type mice, as assessed by the surviva...

Previously we described a reliable method based on immunodepletion for isolating mesenchymal stem cells (MSCs) from murine bone marrow and showed that, after intracranial transplantation, the cells migrated throughout forebrain and cerebellum and adopted neural cell fates. Here we systemically administered MSCs purified by immunodepletion from male bleomycin (BLM)-resistant BALB/c mice into fem...

Bloom syndrome is a rare, autosomal recessive inherited disorder in humans. The product of the Bloom syndrome mutated gene, designated BLM, is a member of the RecQ helicase family. BLM has been proposed to function at the interface of replication and recombination, and to facilitate the repair of DNA damage. Here, we report in vivo physical interaction and colocalization of BLM and a DNA struct...

Spindle assembly checkpoint (SAC) ensures bipolar attachment of chromosomes to the mitotic spindle and is essential for faithful chromosome segregation, thereby preventing chromosome instability (CIN). Genetic evidence suggests a causal link between compromised SAC, CIN, and cancer. Bloom syndrome (BS) is a genetic disorder that predisposes affected individuals to cancer. BS cells exhibit eleva...

The present study investigated the effects of diesel exhaust (DE) on an experimental model of bleomycin (BLM)-induced lung injury and fibrosis in mice. BLM was intravenously administered to both Nrf2+/+ and Nrf2-/- C57BL/6J mice on day 0. The mice were exposed to DE for 56 days from 28 days before the BLM injection to 28 days after the BLM injection. Inhalation of DE induced significant inhibit...

In order for the Bureau of Land Management (BLM) to comply with the Government Performance and Results Act (GPRA), and better meet the needs of the public; a visitor satisfaction survey was conducted at 23 BLM recreation sites in 11 states during fiscal year 2008 (FY08). The survey was developed to measure each site's performance related to BLM GPRA Goal 3.1 Provide for a quality recreation exp...
