The case of a 3 11/12-year-old Chinese boy with the dental abnormalities of "otodental" dysplasia is reported. Hearing was normal. Dental anomalies consisted of delayed eruption of globe-shaped molars, bulbous deciduous canines, and double pulp chambers in the molars. Radiographs taken 4 years later showed taurodontic molars, supernumerary microdontic teeth, retarded formation of premolars, and...

What are they? Dendritic spines are small protrusions that emerge from the dendrites of neurons (Figure 1). Most excitatory synapses in the brain are found on spine heads. Typically, a spine consists of a bulbous head, volume 0.001–1 μm3, at the end of a thin spine neck, diameter around 0.1 μm. A 100 μm length dendrite can contain several hundred spines. The human cerebral cortex is thought to ...

This study aimed (i) to assess the ability of electronic nose (e-nose) technology to differentiate between blood samples of experimentally infected and non-infected subjects, and (ii) to evaluate e-nose responses given by volatile organic compounds in relation to the acute phase reaction generated in the host. In an animal model of gram-negative bacterial infection (20 calves; intratracheal ino...

The electronic nose (e-nose) is designed to crudely mimic the mammalian nose in that most contain sensors that non-selectively interact with odor molecules to produce some sort of signal that is then sent to a computer that uses multivariate statistics to determine patterns in the data. This pattern recognition is used to determine that one sample is similar or different from another based on h...

A new genus and species, Yaobinthrips yangtzei, are described from Southwestern China sharing many character states with the Austro-Oriental genus Parabaliothrips within the Frankliniella genus-group. Within this group the new species is distinguished by the presence of tergal craspeda, a pair of uniquely bulbous modified setae on the fore tibiae, enlarged fore femora with a basal tooth, and pa...

In this paper, electronic nose (E-nose) was used to discriminate the 11 Chinese Materia Medica (CMM) from Umbelliferae by the difference of their odors. The E-nose generated data were analyzed by discriminant function analysis (DFA) and the responses of 18 sensors of E-nose were evaluated by CA analysis. Results showed that a rapid evaluation of complex response of the samples could be obtained...

background the efficiency of nasal surgeries can be determined by objective or subjective methods. we have assessed the effect of nasal obstruction after different nasal surgeries using acoustic rhinometry (ar) and nasal obstruction symptom evaluation (nose) scale. methods between may 2011 and may 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to otorhinol...

In this work, a hypothesis is presented that could explain the non-homogeneous lateral distribution of membrane components in Golgi vesicles. It is shown that the non-homogeneous lateral distribution of membrane components and the specific flattened shape of Golgi vesicles are strongly coupled. In agreement with experimental evidence, it is indicated that some of the membrane components may be ...

AbstractThis paper investigates a novel technique for extraction of the nose-tip from three-dimensional face image in any pose, which is needed for nose-tip based face registration. The present technique uses weighted median filter for smoothing. No normalization process is applied and the system correctly detects nose-tips across any pose variations. In our system, at first the range images ar...
