The purpose of this community service activity is to improve the welfare farming in Humbang Hasundutan, especially farmers Ria-Ria Village, Pollung District through marketing using online media. Farmers must be able adapt technological developments, and access latest information related agriculture marketing, where utilizing digital media a challenge for them. This method carried out by sociali...

The scarcity of mesenchymal stem cells (MSCs) in iliac crest bone marrow aspirate (ICBMA), and the expense and time in culturing cells, has led to the search for alternative harvest sites. The reamer-irrigation-aspirator (RIA) provides continuous irrigation and suction during reaming of long bones. The aspirated contents pass via a filter, trapping bony fragments, before moving into a 'waste' b...

A four-layer antispecies radioimmunoassay (RIA) was developed for the detection of adenovirus in stool specimens. Polystyrene beads were used as the solid phase, anti-adenovirus guinea pig immunoglobulin (1 microgram per bead) was used as the primary antibody, anti-adenovirus rabbit immunoglobulin (16 micrograms/ml) was used as the secondary antibody, and 125I-labeled sheep anti-rabbit immunogl...

Gentamicin levels were determined in 100 serum specimens by a new latex agglutination inhibition card test, a radioimmunoassay (RIA), and a bioassay. Correlation coefficients determined by linear regression analysis demonstrated that the levels obtained by the latex agglutination inhibition card test had a high degree of correlation with the RIA and could be performed much faster and more econo...

A new radioimmunoassay (RIA) method has been de scribed. This radioimmunoelectrophoretic binding (REB) technique has been applied to the carcinoembryonic antigen system. In contrast to the RIA method with the use of perchloric acid extraction, in the REB technique the require ment for lengthy and possibly biologically degrading pro cedures on relatively large volumes of sera has been eliminated...

A radioimmunoassay (RIA) has been developed using 125I-amikacin. Amikacin was iodinated by a modified BOLTON and HUNTER method. Dextran-charcoal was used to separate bound from free drug. The standard curve was linear on a logit-log plot in the range of 0.5 ng to 4 ng amikacin per tube. There was no cross-reactivity of amikacin antisera to the amino-glycosides gentamicin, tobramycin, netilmicin...

We report a case of a long-term local control and survival achieved in a patient affected by radiation-induced angiosarcoma (RIA). A 57-year-old woman had a history of breast-conserving surgery and radiation therapy for primary breast cancer. Eight years after the mastectomy, multiple nodal progression was diagnosed as RIA and subsequentially treated by salvage lymph node dissection followed by...

BACKGROUND Pregnancy-associated glycoproteins (PAGs) were first described as placental antigens present in the blood serum of the mother soon after implantation. Here, we describe the purification of several pregnancy-associated glycoproteins from water buffalo placenta (wbPAGs). A specific radioimmunoassay (RIA) was developed for early pregnancy diagnosis in buffalo species. RESULTS Amino-te...

These studies have evaluated a newly developed radioimmunoassay (RIA) for the measurement of colony-stimulating factor (CSF) in murine serum and other biologic fluids. The routine in vitro agar gel bioassay for CSF is influenced by high molecular weight serum lipoproteins and low molecular weight tissue-derived materials that are inhibitory to colony formation. Studies with normal serum reveale...

Residual flows are of major importance in coastal areas, driving environmental processes such as sediment transport or nutrient dispersion. Consequently, those areas where a large tidal stream energy resource is available, prior to the installation farm, it imperative assess how extraction affects residual and, particular, upwelling events. In this paper, potential effects different configurati...
