Doppler flow velocity waveform recording in the fetal ductus venosus and umbilical artery as well as maternal blood sampling for serum alpha-fetoprotein (MSAFP) was performed before and after transabdominal chorion Mtlus sampling (TACVS) in 36 women of advanced maternal age (3 36 years). Gestational age ranged between 11 and 13 weeks. No chromosomal anomaly was detected. No statistically sigrul...

OBJECTIVE The objective of this study was to assess the feasibility of transplanting embryonic chondrogenic cells within a collagen-fibrin substrate for the reconstitution of full-thickness cartilage defects in chicken knee joints. METHODS Full-thickness cartilage defects were created mechanically on the weight-bearing surface of the tibial condyle in 45 adult chickens and subsequently filled...

Four different paddy soils collected around the Gyeongju nuclear site were treated with TcO4 solution under the assumption of two contrasting contamination scenarios. Scenario I (SN-I) is for a pre-transplanting deposition of Tc followed by plowing, whereas SN-II is for its deposition onto the water surface shortly after transplanting. Rice plants were grown in lysimeters in a greenhouse. Plant...

The aim of this study was to assess the feasibility of transplanting mesenchymal stem cells (MSCs), genetically modified to express glial-derived neurotrophic factor (GDNF), to the contused rat spinal cord, and to subsequently assess their neural differentiation potential. MSCs expressing green fluorescent protein were transduced with a retroviral vector to express the neurotrophin GDNF. The tr...

A pre-nursery system fur raising coconut seedlings was compared with the conventional nursery. The two major refinements introduced in the pre-nursery system are the slicing of seed nuts and transplanting of sprouted seed nuts from pre-nursery beds to nurserv beds, soon after sprouting. The rate of sprouting in the Pre-nursery system was significantly superior. At the end of 20 weeks 76% of the...

The present study was conducted in an attempt to treat streptozotocin (STZ)-induced hyperglycemia by transplanting beta cells derived from pancreatic ductal cells. Ductal cells obtained from neonatal rats were cultured in vitro. Approximately 70% of the cells were converted to insulin-secreting cells by incubating with betacellulin and activin A. Differentiated cells responded to a depolarizing...

This study investigated changes in serum levels of hepatic, bone, and intestinal alkaline phosphatase (ALP) isoenzymes (ALP2, ALP3, ALP5, respectively) Holstein cows around parturition. Tartrate-resistant acid 5b (TRAP5b) activity calcium (Ca) concen-trations were also measured. We analyzed blood samples from 11 late-pregnant heifers (primipa-rous group) 13 multiparous (2-4 lactations; at 3 wee...
