A series of biochemical determination and electrophoretic observations have been conducted to analyze the activities and characteristics of protease, α-amylase, and lipase of paddlefish Polyodon spathula. The results obtained have been compared with those of bighead carp (Aristichthys nobilis) and hybrid sturgeon (Huso dauricus ♀ × Acipenser schrenki Brandt(More)
To assess the effect of dietary ascorbate on lipid metabolism, 1-year black sea bream (Acanthopagrus schlegelii) were reared on a casein-based purified diet and an ascorbate fortified diet (1,100 mg of l-ascorbyl-2- monophosphate-Mg/kg diet). The fortified ascorbate was effectively incorporated into the fish body and elevated muscle carnitine content.(More)
Intermittent and low-dose parathyroid hormone (PTH) injection to stimulate bone formation has been used in the treatment of osteoporosis. The N-terminal fragment 1–34 of PTH is quite similar in structure and function to N-terminal PTH-related protein (PTHrP). PTH(1–34) and PTHrP also share a coreceptor, the PTH/PTHrP receptor. Therefore, some studies have(More)
Osteoporosis is one of the leading disorders among aged people. Bone loss results from a number of physiological alterations, such as estrogen decline and aging. Meanwhile, iron overload has been recognized as a risk factor for bone loss. Systemic iron homeostasis is fundamentally governed by the hepcidin-ferroportin regulatory axis, where hepcidin is the(More)
Iron overload has been associated with bone mass loss. To elucidate the effects of excess iron on bone metabolism, an iron-overloading mouse model was established by administering iron-dextran at 250 mg/kg to female BALB/c mice. After 4 weeks, the mice were sacrificed and the biomechanical properties of the femurs were examined. The results suggested a(More)
Fisher linear discriminant analysis(FLDA) is a classical and important algorithm for face recognition. However, the FLDA will fail when there have only one sample each object, because the intra-class scatter matrices cannot be calculated. In this paper, an adaptive virtual sample generation method based on singular value decomposition(SVD) is proposed to(More)
This study was performed to characterize the bone metabolism in ten 6-month-old male Goto-Kakizaki (GK) rats, a spontaneous type 2 diabetic model, with ten age- and sex-matched non-diabetic Wistar rats as controls. The femora and the fifth lumbar vertebrae were analyzed by a dual energy X-ray absorptiometry for bone mineral density. Histomorphometrical(More)
Iron is essential for the human being, involving in oxygen transport, energy metabolism and DNA synthesis. Iron homeostasis is tightly governed by the hepcidin-ferroportin axis, of which hepcidin is the master regulator. Excess iron is associated with various diseases including osteopenia and osteoporosis, which are closely related to the alternation of the(More)
Image segmentation is a huge task and challenge in the magnetic resonance images (MRI) and infrared images because of the intensity inhomogeneity, noisy and other problems. It is of importance to distinguish each region accurately to obtain a perfect segmentation result. Methods based on bias field theory can effectively overcome the intensity(More)
