The study of the effect on the internal organs of mice of the application of carcinogenic agents to the skin has occupied our attention during recent years, a preliminary analysis of findings in several thousand animals having already been published (1). Most of these earlier experiments were performed with the primary object of testing the reaction of the skin to various carcinogenic agents. M...

abstract currently in iran, some manual methods are used for measuring spray droplet size which is very laborious and time consuming. in this paper, a software is presented based on image processing techniques, which is suitable for small object detection purpose that can be used in blob analysis of sprayer calibration and other similar applications. the algorithms have been implemented and ada...

The striking success of antihistaminic agents such as pyribenzamine, benadryl and several others in controling the nasal turgescence and rhinorrhea of seasonal hay fever, and in relieving the symptoms of urticaria, led to exaggerated hopes of similar results in the treatment of asthma. While the effectiveness of antihistaminic agents has lent considerable support to the role of histamine in all...

OBJECTIVE The purpose of this study was to determine whether the continuous glucose monitoring system (CGMS) (MiniMed, Sylmar, CA) 1) is sufficiently representative of the overall metabolic control as assessed by HbA(1c), 2) could be used to identify a particular blood glucose threshold value affecting hemoglobin glycation; and 3) is able to show any relationship between particular glycemic pro...

This study compared the application and reliability of 4 methods for biofilm quantification (computerized, paper-weighing, point-counting, and planimetric) in complete dentures, verifying the correlation between them. The internal surfaces of 62 complete dentures were stained (5% erythrosine) and photographed. The slides were projected on paper, and the areas (total and biofilm-covered) were ou...

This paper presents a 3D phenotyping method applied to sunflower, allowing to compute the leaf area of an isolated plant. This is a preliminary step towards the automated monitoring of leaf area and plant growth through the plant life cycle. First, a model-based segmentation method is applied to 3D data derived from RGB images acquired on sunflower plants grown in pots. The RGB image acquisitio...

The proliferative response in a healing wound to a constant amount of injury offers an opportunity to study the factors that influence the velocity of growth of the injured cells. An attempt will be made to review here some of the studies on sterile wounds with reference to those factors which have been found to influence cellular proliferation, and to present the substantiating investigations ...

GREENWOOD et al. [1935] have discussed certain quantitative aspects of the capon comb response to androsterone. In view of the need for economy in both time and material a comparatively small degree of response is most suitable for assay work. Thus the criteria commonly used, a 20 % increase in area or an increase of 5 mm. in length+ height, take the capon comb only a fraction of the way toward...

Pressure ulcers (also known as bedsores or decubitus ulcers) are areas of localised injury to the skin and underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear forces. This type of ulcer is one of the most common complications in patients with spinal cord injury. Treatment with transcutaneous electrical stimulation, and with acupunctur...

Contractures of the fingers producing a claw hand may be due to nerve lesions (ulnar palsy), muscle lesions (haemophilia or traumatic Volkman's contracture and dermatomyositis), skin lesions (scleroderma), fascial lesions (Dupuytren's contracture), joint lesions (rheumatoid arthritis or osteo-arthritis), or lesions of the tendons and tendon sheaths. The most common lesion of the tendon is a tra...
