Symptomatic bilateral massive pulmonary embolism and proximal and distal deep vein thrombosis following arthroscopic meniscus surgery
Autor: Geon Ho Kwon, Man Soo Kim, Sang Hyun Jeon
Publikováno v: Medicine
Rationale: The incidence of venous thromboembolism (VTE) after knee arthroscopy is remarkably lower than that of arthroplasty. We describe a patient with symptomatic bilateral massive pulmonary thromboembolism (PTE) and deep vein thrombosis (DVT) in

Association of bone mineral density with the development of knee osteoarthritis in men and women: a cross-sectional study using the fourth and fifth Korea National Health and Nutrition Examination Surveys
Autor: Kyoung Geun Lee, Man Soo Kim, Sang Hyun Jeon
Publikováno v: Archives of osteoporosis. 15(1)
Bone mineral density (BMD) and osteoarthritis (OA) were correlated but the relationship was varied according to sex. An association between lumbar spine and femur neck BMDs and OA showed a positive relation in women, while lumbar spine and pelvis BMD

Efficient Synthesis of Individual Single-Walled Carbon Nanotube by Water-Based Catalyst with Poly(vinylpyrrolidone)
Autor: Kay Hyeok An, Dong Jae Bae, Seung Yol Jeong, Minhee Yun, Gang Hee Han, Ha Ryong Hwang, Sang Hyun Jeon, Seuong Chu Lim, Chang Soo Han, Young Hee Lee
Publikováno v: Journal of Nanoscience and Nanotechnology. 8:329-334
Individual single-walled carbon nanotubes (SWCNTs) were synthesized on the patterned water-soluble catalyst by thermal chemical vapor deposition. The individual SWCNTs were obtained by introducing polyvinylpyrrolidone (PVP) as a dispersant. The numbe
