Determination of gene expression is essential for understanding the role of a given gene in normal cell growth or disease processes. Recently, newly described microRNAs have been shown to play a key role in the regulation of gene expression; in particular, deregulation of microRNAs is often associated with a variety of human disorders including cancer.(More)
A study was undertaken to determine the predictive capability of Annualized Agricultural NonPoint Source (AnnAGNPS) model with respect to runoff volume, peak flows, and sediment yield from a 130.8 ha watershed in the Siwalik Hills of Nepal. AnnAGNPS simulations are compared with two years of field observations from the study watershed. The model predicted(More)
The purpose of this study was to develop single walled carbon nanotubes (SWCNT) and poly lactic-co-glycolic acid (PLAGA) composites for orthopedic applications and to evaluate the interaction of human stem cells (hBMSCs) and osteoblasts (MC3T3-E1 cells) via cell growth, proliferation, gene expression, extracellular matrix production and mineralization.(More)
The purpose of this study was to develop three-dimensional single-walled carbon nanotube composites (SWCNT/PLAGA) using 10-mg single-walled carbon nanotubes (SWCNT) for bone regeneration and to determine the mechanical strength of the composites, and to evaluate the interaction of MC3T3-E1 cells via cell adhesion, growth, survival, proliferation, and gene(More)

Diagnosis of breast cancer from mammograms is a crucial task. CBIR can support radiologists in their decision to retrieve similar mammograms out of a database to compare the past cases with current case. Pectoral muscle, labels, and artifacts, present in mammograms can bias the detection procedures. So extractions of these are an essential preprocessing(More)
Bone graft substitutes are widely used in the field of orthopedics and are extensively used to promote vertebral fusion. Fusion is the most common technique in spine surgery and is used to treat morbidities and relieve discomfort. Allograft and autograft bone substitutes are currently the most commonly used bone grafts to promote fusion. These approaches(More)
Summary The development of population in Bangladesh was affected by a succession of man-made and natural calamities, such as the Bengal Famine of 1943, refugee movements following the partition of India and Pakistan in 1947, devastating floods and cyclones around 1970, and the military action during the war of liberation. Though there had been a tradition(More)
The issues of water resources management are addressed with specific reference to the available water resources and water demand for the Chao Phraya River basin in Thailand. The water resources management practices in most of the countries in southeast Asia have been generally on a sectoral level without consideration of any intersectoral interference and(More)
