To investigate in vitro differentiation of canine adipose tissue-derived stromal cells (ATSCs) into neuronal cells, ATSCs from celiac adipose tissue in clinically healthy beagle dogs were treated with 100 muM dibutyryl cyclic adenosine monophosphate (dbcAMP) and 125 muM isobuthylmethylxanthine (IBMX). ATSCs were morphologically changed into differentiated ATSCs from spindle-shaped cells to neuron-like cells with numerous processes after the treatment. Expression of neuron-specific enolase (NSE) as an early neuron specific marker protein was detected in both ATSCs and differentiated ATSCs, however diachronic increase of NSE expression was observed in differentiated ATSCs after the treatment with dbcAMP/IBMX. In addition, neurofilament-68 (NF-68) as an early to mature neuron specific marker protein was weakly expressed in differentiated ATSCs. Neuron specific glutamate and glucose transporter (EAAC1 and GLUT-3, respectively) mRNAs were strongly expressed in differentiated ATSCs compared with those in ATSCs, although glia specific glutamate transporter mRNA (GLT-1) was also detected in differentiated ATSCs. ATSCs can differentiate into early to mature neuronal cells and are candidate cells for autologous nerve regeneration therapy, although additional research is needed to examine functional characteristics of differentiated ATSCs. 相似文献

An epidemiological study of Babesia canis in dogs in Nigeria was performed. Four hundred blood samples collected from dogs in Nigeria were investigated using nested PCR and sequence analysis. On nested PCR screening, nine samples (2.3%) produced a band corresponding to a 698-bp fragment indicative of B. canis infection. Sequence analysis of the PCR products identified eight samples (2.0%) as B. canis rossi and the ninth (0.3%) as B. canis vogeli. This is the first report of the prevalence of B. canis rossi and B. canis vogeli in dogs in Nigeria. 相似文献

Recently, it has been reported that neonicotinoid pesticides (NNs) are transferred from mother to child and are assumed to affect the next generation, but the behavioral effects of NN exposure at different developmental stages have not been investigated. We exposed mice to no-observed-adverse-effect level (NOAEL) doses of clothianidin (CLO) during the fetal and lactational period, and then evaluated the neurobehavioral effects in juvenile and adult mice. Significant increases in anxiety-like behavior and locomotor activity were observed in juveniles and adults, respectively, and neuronal activity and neurogenesis in the hippocampal dentate gyrus were affected in both stages. These results suggest that fetal and lactational exposure to CLO may inhibit neurogenesis and cause different behavioral abnormalities at different developmental stages. 相似文献

A method for visualizing the sugar content in the flesh of melons was developed. This method was based on the sugar absorption band in the near-infrared (NIR) region to avoid bias caused by the color information of a sample. NIR spectroscopic analysis revealed that each of the two second-derivative absorbances at 874 and 902 nm had a high correlation with the sugar content of melons. A high-resolution cooled charged couple device camera with band-pass filters, which included the above two wavelengths, was used to capture the spectral absorption image of a half-cut melon. A color distribution map of the sugar content on the surface of the melon was constructed by applying the NIR spectroscopy theory to each pixel of the acquired images. 相似文献
