BACKGROUND Tissue expanders are used in breast reconstruction after mastectomy to stretch the remaining tissue to create space for placement of permanent breast implants. The AeroForm™ Tissue Expander, developed by AirXpanders™ Inc., contains electronic components designed to activate the release of carbon dioxide from an internal reservoir to inflate the expander. Breast cancer patients who un...
This study analyzed occlusal radiographs to compare the transverse changes produced in patients treated with rapid maxillary expansion using two types of appliances. The sample consisted of 31 children aged 7 to 10.6 years, of both genders, with posterior cross-bite. Fifteen children were treated with a tooth-borne expander and 16 were treated with a tooth-tissue-borne expander. Occlusal radiog...
BACKGROUND In this finite element (FE) study, the stress distribution and displacement pattern was evaluated in the mid-palatal area and around circum-maxillary sutures exerted by bone-borne palatal expander (BBPE) in comparison with conventional HYRAX rapid palatal expander in unilateral cleft lip and palate. METHODS Computed tomography scan images of a patient with unilateral cleft palate w...
An organic Rankine cycle (ORC) is a power cycle employing an organic working fluid. The term ORC is also applied generally to any Rankine cycle with a low-grade heat source (80° – 300 o C). Because ORC are often employed in small-scale applications, use of positive displacement equipment is favored over the centrifugal units used in large-scale power plants. A key feature of a positive displace...
Introduction: With the impossibility of prosthetic implantation with a definitive final volume due to dehiscence and posterior extrusion risks, the development of skin-sparing mastectomy provides an ideal condition for the use of a definitive expander implant. Therefore, this study aimed to demonstrate the use of a definitive expander implant and discuss its indications, cutaneous incision, and...
Use of tissue expander in the recent decade has revolutionized the plastic surgery. The tissue expansion technique is advantageous in body reconstruction because it makes it possible to resurface the defects resulting from excision of burn scars with neighboring skin similar in color and texture and superior to skin grafts or distant flaps. Treatment of burn alopecia was a major problem in the ...
Of 14 cases who underwent this operation only in one of them because of infection in operation site, we had to extract the expander. Also, in the first day of the operation that we injected serum inside the expander of two other patients, the wound opened up and the expander appeared and came out automatically. The remaining ten patients have tolerated the operation after treatment period witho...
Pregnant cows were fed pine needles (PN, 2 kg.cow-1.d-1) mixed with the diet to determine factors that affect abortion response. In Exp. 1, treatments were used to determine the effects of experimental stress and pelleting of pine needles. Pelleting needles and experimental stress delayed abortion response (P < .01). Stress-induced delay was associated with abnormal patterns of progesterone and...
