OBJECTIVE The aim of this study was to evaluate the microanatomy and histological features of the central myelin in the root exit zone of facial nerve. METHODS Forty facial nerves with brain stem were obtained from 20 formalin fixed cadavers. Among them 17 facial nerves were ruined during preparation and 23 root entry zone (REZ) of facial nerves could be examined. The length of medial REZ, fr...

The aim of this work was to evaluate the effect of earthworms (Lumbricidae) on the enzymatic activity and microbial functional diversity in the burrow system [burrow wall (BW) 0-3 mm, transitional zone (TZ) 3-7 mm, bulk soil (BS) > 20 mm from the BW] and cast aggregates of a loess soil under a pear orchard. The dehydrogenase, β-glucosidase, protease, alkaline phosphomonoesterase, and acid phosp...

Carcinoembryonic antigen (CEA), secretory component (SC), and epithelial IgA were traced by paired immunofluorescence staining in 102 large bowel carcinomas from 99 patients. The immunohistochemical results were evaluated semiquantitatively in relation to histological tumour grade, clinicopathological stage, and preoperative plasma CEA concentration. CEA expression was significantly increased (...

Using a farm household data from 3 agroecological zones of Ghana, this paper investigates the causal relationship between the adoption of improved maize variety and technical efficiency or productivity. The empirical results show a positive relationship between the adoption of improved maize variety and technical efficiency or productivity of farmers in the Semi-deciduous forest and Guinea Sava...

OBJECTIVE The tubercle of Zuckerkandl (TZ) is a lateral projection from the thyroid lobe in the vicinity of the extralaryngeal termination of the recurrent laryngeal nerve (RLN), which is a very useful landmark for identification of the RLN during thyroidectomy. The purpose of the present study was to test our hypothesis that the TZ is more consistently found and is larger on the right than on ...

We investigated the accuracy of a double-injection method for sequentially measuring cerebral blood flow (CBF) with N-isopropyl-(123I)p-iodoamphetamine (IMP) in simulation studies based on patient data and in clinical studies. The unidirectional clearance of IMP from the blood to the brain (K1; nearly equal to CBF) in the first and second sessions was calculated by means of a microsphere model....

PURPOSE To establish a tear analytical model by using Raman microspectroscopy to assess ocular surface diseases associated with infectious pathogens. METHODS The authors applied confocal Raman microspectroscopy based on the drop-coating deposition method on Ti/Au-coated glass slides to obtain sample spectra from different types of tears, including simplified synthetic tears (SSTs), SSTs mixed...
