Microtubules are classically described as being transverse, which is perpendicular to the direction of cell elongation. However, fixation studies have indicated that microtubules can be variably aligned across the epidermis of elongating shoots. In addition, microtubules are reported to have different orientations on inner and outer epidermal surfaces, undermining the idea of hoop-reinforcement...

External thermal insulation systems often have durability problems, including cracking, hollowing, and falling off, which seriously affect safety energy-saving effects. Based on finite element theory using ANSYS software, this paper studies the distribution law of temperature field stress external system. It was found that, compared with an uninsulated wall, substrate in summer reduced by 52.9%...

INTRODUCTION Phyllodes tumors are uncommon biphasic fibroepithelial neoplasms of the breast of varying malignant potential occurring in middle aged women. They exhibit diverse biological behavior. Margin free excision is the mainstay of treatment. CASE PRESENTATION A 27 year-old lady was referred with a painless ulceroproliferative right breast lesion which had rapidly progressed over six mon...

BACKGROUND The epithelial reticular basement membrane (Rbm) of the airway wall thickens in patients with asthma. However, whether the thickening parallels whole airway wall thickening, which limits airflow, is unknown. The aim of this study was to examine the correlation between the bronchial Rbm thickening and whole airway wall thickening in asthma. In addition, the association of Rbm and whol...

Skeletal tuberculosis is usually seen in association with primary pulmonary form. Pulmonary tuberculosis of the chest wall is a rare entity. We herein report a case of tuberculosis of the chest wall without pulmonary involvement that presented with big ulcer in the anterior chest wall and responded completely to the antituberculosis therapy without any surgical intervention.

see through the wall radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars. in this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. then using a dielect...

Airway segmentation and analysis is an essential step in the understanding of pulmonary anatomy and early detection of lung diseases. In this paper, we evaluate a newly developed method for segmenting the inner and outer surfaces of the airway tree. This is the first approach reported to validate the segmentation of the double wall surfaces for the entire airway tree including bifurcations. Two...

PURPOSE Small artery and arteriolar walls thicken due to elevated blood pressure. Vascular wall thickness show a correlation with hypertensive subject history and risk for stroke and cardiovascular events. METHODS The inner and outer diameter of retinal arterioles from less than 10 to over 150 μm were measured using a multiply scattered light adaptive optics scanning laser ophthalmoscope (AOS...

The ascospore wall of the budding yeast Saccharomyces cerevisiae consists of inner layers of similar composition to the vegetative cell wall and outer layers made of spore-specific components that confer increased stress resistance on the spore. The primary constituents of the outer spore wall are chitosan, dityrosine, and a third component termed Chi that has been identified by spectrometry bu...
