BACKGROUND While the treatment for displaced femoral neck fractures in the elderly (Garden types III and IV) is quite clear, the procedure for impacted or undisplaced femoral neck fractures (Garden types I and II) is still a subject of controversy. METHODS Thirty-seven (all >80 years old) patients with undisplaced femoral neck fractures were treated with(More)
Radio frequency identification has been developed and used in many applications in the real world. Due to the shared wireless channel between tags and the reader during communication, the tag collision arbitration is a significant issue for reducing the communication overhead. This paper presents a novel anti-collision algorithm named New Enhanced(More)
Triple-negative breast cancer (TNBC) is defined by a lack of expression of the estrogen receptor (ER), progesterone receptor (PR), and epidermal growth factor receptor 2 (HER 2). Therefore, targeted therapy agents may not be used, and therapy is largely limited to chemotherapy. Doxorubicin treatment consequently acquires undesired malignance characteristics(More)
IMPORTANCE Transnasal esophagoscopy or pandoscopy to conduct a tumor survey is routinely recommended for patients with head and neck squamous cell carcinoma (HNSCC). Despite this recommendation, the effect of routine esophageal screening remains unclear. OBJECTIVE To investigate the effect of routine esophageal screening on the detection of second primary(More)
Radio frequency identification has been developed for many years and it got much attention from researchers recently as there are lots of applications being used practically in the real world. Owing to the shared wireless channel between tags and reader during communication, the tag collision arbitration is a significant issue for reducing the communication(More)
C-reactive protein (CRP) is an acute phase reactant and its level rises rapidly during inflammation. Recent studies have suggested the potential involvement of CRP in the pathogenesis of age-related macular degeneration (AMD). To delineate the functional roles of CRP in inflammatory response by the ocular posterior segments, the effects of CRP on ARPE-19,(More)
BACKGROUND Jugular venous reflux (JVR) has been reported to cause cough syncope via retrograde-transmitted venous hypertension and consequently decreased cerebral blood flow (CBF). Unmatched frequencies of JVR and cough syncope led us to postulate that there should be additional factors combined with JVR to exaggerate CBF decrement during cough, leading to(More)
Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumor of the salivary glands made up of clear cells that form cords and nests in hyalinized stroma. To date, primary HCCCs of the paranasal sinus have not been described. This article presents 2 cases of HCCC of the maxillary sinus with unusual glandular formation and lymphoplasmacytic stroma in(More)
BACKGROUND Vascularized iliac bone-grafting has been reported to be successful for patients with osteonecrosis of the femoral head. However, its benefit in patients with segmental collapse of the femoral head has not been determined. The purpose of this study was to analyze the results of vascularized iliac grafting in osteonecrotic femoral heads with(More)
