Mucinous carcinoid of the ovary: report of a case with metastasis in the contralateral ovary after ten years
Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate
A Thermoplastic Elastomer Belt Based Robotic Gripper
Novel robotic grippers have captured increasing interests recently because of
their abilities to adapt to varieties of circumstances and their powerful
functionalities. Differing from traditional gripper with mechanical
components-made fingers, novel robotic grippers are typically made of novel
structures and materials, using a novel manufacturing process. In this paper, a
novel robotic gripper with external frame and internal thermoplastic elastomer
belt-made net is proposed. The gripper grasps objects using the friction
between the net and objects. It has the ability of adaptive gripping through
flexible contact surface. Stress simulation has been used to explore the
regularity between the normal stress on the net and the deformation of the net.
Experiments are conducted on a variety of objects to measure the force needed
to reliably grip and hold the object. Test results show that the gripper can
successfully grip objects with varying shape, dimensions, and textures. It is
promising that the gripper can be used for grasping fragile objects in the
industry or out in the field, and also grasping the marine organisms without
hurting them
