Tumor necrosis factor-alpha (TNF-alpha) is considered a promoter of bone resorption and a suppressor of osteogenesis, whereas bone morphogenetic protein (BMP) is a promoter of bone formation. In the present study, the osteogenic potential of the medullary cavity after bone marrow ablation was evaluated in association with the pattern of BMP, bone(More)
The purpose of this study was to evaluate the usefulness of a combination regimen of anabolic and antiresorptive agents in increasing skeletal quantity and quality in comparison to a single-drug regimen with these agents. We examined histomorphometrically and biomechanically the effects of separate and combined administration of intermittent parathyroid(More)
In vivo, the BLV proviral DNA usually resides in a transcriptionally inert state, and is hypermethylated. Upon short-term in vitro cultivation of the neoplastic or non-neoplastic lymphoid cells, the viral genome becomes transcriptionally active but without detectable change in its methylation state. Proviral DNA was found to be methylated in one but not in(More)
The two species of covalently closed circular DNA molecules of bovine leukemia virus were cloned in the lambda phage vector lambda gtWES X lambda B. Of the nine independent recombinant lambda-bovine leukemia virus clones that were analyzed, three were derived from the small and six were derived from the large circular molecules carrying, respectively, one(More)
Western blot analyses were performed on 444 serum specimens: 40 sera from microfilaraemic individuals, 10 sera from elephantiasis patients, 24 treated individuals, 50 sera from residents of endemic areas without anti-filarial IgG4 antibodies (endemic normals), 20 sera from amicrofilaraemic individuals with high anti-filarial IgG4 antibodies, 200 sera from(More)
Cocultivation of uninfected and bovine leukemia virus-producing bat cells yielded, in addition to the unintegrated linear DNA duplex, DNA molecules that migrated as 4.4- and 4.8-kilobase-pair DNA fragments in gel electrophoresis. These DNA molecules were purified by acid-phenol extraction and cleaved with restriction endonucleases EcoRI, and HindIII, which(More)
A total of 1,134 finger-pricked blood samples were collected from residents of Setiu, Terengganu. A drop of blood was used to make thick blood smear and about four drops were used for obtaining serum. The smears were stained and examined by the State Vector Control Unit in Kuala Terengganu, while the serum samples were tested for specific IgG4 antibodies to(More)
BACKGROUND Bone morphogenetic protein (BMP) activity has been found in cases of malignant fibrous histiocytoma (MFH) and osteosarcoma but only tumors in the latter category show evidence of ossification. The aim of this study was to try to understand this difference by examination of the distribution of BMP and its receptors (BMPR) for this bone inducing(More)
Sera from fifty subjects with different presentations of Brugian filariasis and from common soil-transmitted helminth infections were tested for specific anti-filarial IgG and its subclasses. Anti-filarial IgG, IgG1 and IgG3 showed cross-reactivities with soil-transmitted helminthic infections and no significant differences in optical densities among the(More)
