Working memory (WM) has been thought to include not only short-term memory stores but also executive processes that operate on the contents of memory. The present study examined the involvement of WM in search using a dual-task paradigm in which participants performed visual search while manipulating or simply maintaining information held in WM. Experiments 1a and 2a involved executive WM tasks that required counting backward from a target digit and sorting a string of letters alphabetically, re

Inverted nipples have been treated by various methods by many authors, but the relationship between the grade of the deformity and the appropriate surgical procedure is not clearly described. One hundred seven inverted nipples in 60 patients were treated from 1993 to 1997. They were divided into three groups by the authors' system of grading. The grade was made by preoperative evaluation of severity of inversion and was confirmed by the surgical findings. In grade I, the nipple is easily pulled

These findings suggested that dexamethasone inhibits AKT and ERK phosphorylation, leading to decreased CYR61 expression, which in turn blocks TGF-β1-induced migration.

Neurofibromatosis type 1 (von Recklinghausen's disease, NF-1) is an autosomal-dominant neurocutaneous disorder characterized by abnormal skin pigmentation (café au lait spots and axillary freckling), cutaneous and plexiform neurofibromas, skeletal dysplasias, and Lisch nodules (pigmented iris hamartomas). Gastrointestinal stromal tumors (GISTs) are the most common tumors of mesenchymal origin in the gastrointestinal tract, mesentery, omentum, and retroperitoneum. Here, we report a case of GIST i

Human epidermal growth factor receptor 2 (HER2) is implicated in several cancers, including gastric cancer. However, limited data are available regarding its clinical significance in early gastric cancer (EGC). We evaluated the clinical significance of HER2 overexpression in patients with EGC. We retrospectively reviewed 727 patients who underwent surgical treatment for EGC between October 2010 and August 2017. HER2 expression was analysed in 680 EGC cases by immunohistochemistry and classified

In Korean SCI patients, FMP showed good correlation with the duration of SCI and the extent of SCI, while BMI did not. Especially in the motor complete tetraplegia group, the diagnostic value of BMI decreased as the duration after SCI increased. This study suggested that FMP could be used complementarily when evaluating the obesity of SCI patients.

Non-Hodgkin lymphoma only rarely occurs as a primary lung mass. We report a very rare case of primary pulmonary anaplastic large cell lymphoma presenting with acute atelectasis in a 55-year-old man. Chest computed tomography revealed a consolidated central mass in the left lung with obstructive pneumonia that had developed into total atelectasis. After a bronchoscopic examination failed to yield a definite diagnosis, supraclavicular lymph node biopsy was performed, revealing an anaplastic large

The transverse rectus abdominis musculocutaneous (TRAM) flap, as the standard for breast reconstruction, can be performed in selected patients with operation scars in the abdomen. It is questioned why the unilateral TRAM flaps raised from the abdomen with scars seem to have more blood supply to the periphery. The effect of the abdominal midline incision on the survival of the TRAM flap was studied with the rat model. The survival of the inferiorly based unilateral TRAM flap was compared between

OBJECTIVE: Numerous methods have been introduced for correction of the cleft lip nasal deformities, but no single procedure has given sufficiently satisfactory results to provide a surgical standard. Much effort has been put on restoring cartilaginous structures using alar cartilage modification and suspension. But even after the cartilage framework is repositioned well, redundant alar webbing is still unsightly and frequently conspicuous. This paper presents a procedure combining the usual open

Lung cancer may rarely appear with a solitary rectal metastasis and no other metastases. We report the first case of primary small cell lung cancer presenting with a solitary rectal metastasis in a 62-year-old man. Chest computed tomography revealed a soft tissue lesion in the subcarinal area. Following bronchoscopic biopsy, the patient was diagnosed with small cell lung cancer. The rectal mass was incidentally found during an imaging study for staging work-up. Histological examination revealed

Extreme Ultra Violet Lithography (EUVL) is one of the most advanced patterning technologies to overcome the critical resolution limits of current ArF lithography for 30nm generation node and beyond. Since EUVL mask manufacturing process has not been fully stabilized yet, it is still suffering from many defect issues such as blank defects, defects inside multilayer causing phase defects, CD defects, LERs (Line Edge Roughness), and so on. One of the most important roles in mask manufacturing proce

Head and neck squamous cell carcinoma (HNSCC) is a spectrum of heterogeneous malignancies. A variety of genetic, environmental, and lifestyle factors contribute to the development of HNSCC. Carcinogenesis is a multistep process in which cell proliferation-associated oncogenes and cell-cycle regulation-associated tumor suppressor genes are dysregulated, resulting in premalignant lesions. Immune evasion is a critical step in the progression of benign lesions to advanced cancer. This review discuss

BACKGROUND: Thalidomide has been reported to have antitumor activity for treating metastatic hepatocellular carcinoma (HCC). We evaluated the safety and efficacy of using thalidomide for treating selected patients with unresectable or metastatic HCC, and their disease was refractory to systemic chemotherapy. METHODS: Eight patients with measurable and metastatic HCC that had progressed with prior systemic chemotherapy and who desired further active therapy were enrolled in this study. Thalidomid

There is little consensus in the literature about the administration of crizotinib in patients with end-stage renal disease undergoing hemodialysis. A 69-year-old male patient, who was receiving regular hemodialysis due to end-stage renal disease, visited the hospital with symptoms of repeated abdominal pain. There was no suspicious finding of cancer within the thorax. After biopsy, the abdominal lymph nodes were identified as adenocarcinoma originating from the lung following computed tomograph
