Demonstrating quantum algorithm acceleration with NMR quantum computer

In general, a quantum circuit is constructed with elementary gates, such as one-qubit gates and CNOT gates. It is possible, however, to speed up the execution time of a given circuit by merging those elementary gates together into larger modules, such that the desired unitary matrix expressing the algorithm is directly implemented. We demonstrate this by taking the two-qubit Grover's algorithm implemented in NMR quantum computation, whose pseudopure state is generated by cyclic permutations of the state populations. This is the first exact time-optimal solution, to our knowledge, obtained for a self-contained quantum algorithm.Comment: 6 pages, revtex, 1 table, experimental details added, 1 figure adde

Optimal therapy for thymoma

Thymoma is the most common tumor of the anterior mediastinum. This tumor is associated with unique paraneoplastic syndromes (myasthenia gravis, pure red cell aplasia, hypogammaglobulinemia, and other autoimmune diseases). The rarity of this tumor has somewhat obscured the optimal treatment. Although the histologic classification of thymoma has remained a subject of controversy for many years, the WHO classification system, published in 1999, appeared to be an advance in our understanding of thymoma. The optimal treatment for thymoma depends on its clinical stage. Surgery remains the mainstay of treatment for thymic epithelial tumors. Thymomas also have a high response rate to chemotherapy or radiotherapy. Only surgical resection is performed for patients with stage I (non-invasive) thymoma. The value of postoperative radiotherapy in completely resected stage II or III tumors is questionable. Multimodality therapy involving surgery, chemotherapy and radiotherapy appears to increase the rate of complete resection and survival in advanced (stage III and IV) thymomas

Although the histologic classification of thymoma has remained a subject of controversy for many years, The WHO classification system, which published in 1999, appear to be an advance in our understanding of thymoma. The optimal treatment of thymoma is performed according to its clinical stage. Surgery remains the mainstay of treatment for thymic epithelial tumors. Thymomas also have a high response rate to chemotherapy or radiotherapy. There are several differences between thymoma and thymic carcinoma. Thymoma is a functional tumor, but thymic carcinoma is not. Thymoma has p 53 protein expressions infrequently, and lower incidence of DNA methylation of cancer-related genes comparing with thymic carcinoma. Although thymoma shows cytologically benign, it invades to neighbor organs, disseminates in the thoracic cavity, and rarely metastasizes to the lymph nodes or distant organs. The invasiveness of thymoma is related to increased expression of matrix metalloproteinase and tissue inhibitor of metalloproteinase

Resilience in cancer care : What should nurses do?

Cancer is a serious threat to human health worldwide. Attention to the quality of life (QoL) of cancer patients is increasingly recognized as an important component of and a fundamental task in cancer care. Recent studies illustrate that resilience is a key biological factor affecting cancer patients’ health status and QoL. However, few studies have focused on resilience during medical procedures of cancer patients from the perspective of nursing. In this study, we summarize recent literature exploring the clinical significance of resilience in oncology nursing, propose strategies for cancer care to improve the QoL of patients through interventions on resilience, and focus on emerging theories in oncology nursing. In summary, this will emphasize the importance of resilience in oncology nursing and benefit the clinical practices that improve patients’ QoL and reduce the social burden caused by cancer

The relation between the cancer screening rate and the cancer mortality rate in Japan

The aim of this research was to clarify the relation between the screening rates for five cancers (lung cancer, stomach cancer, colorectal cancer, uterus cancer, and breast cancer) and their mortality rate by using publicly accessible databases. The used information materials were those prepared by the Ministry of Health, Labour and Welfare, the Center for Cancer Control and Information Services, and the National Cancer Center. Our results were as follows : 1) regarding stomach and colorectal cancers, a positive correlation was found between the screening rate and the mortality rate (p<0.001) ; 2) in the relation between the screening rate and the mortality rate according to administrative divisions, the mortality rate decreased significantly when the lung cancer screening rate improved (p<0.005) ; 3) the mortality rate for breast cancer increased in those aged 50 or over ; 4) the mortality rate for uterus cancer had been slightly increasing since 1990 ; and 5) regarding the screening rate, a positive correlation was found between breast cancer and uterus cancer (p<0.001). In future, improvement in lifestyle and in the knowledge of cancer should be promoted to enhance the screening rates

Interventional bronchology in the lung cancer

Patients with advanced bronchogenic carcinomas that obstruct the central airway have been treated by Nd-YAG laser and tracheobronchial prostheses. The Nd-YAG laser delivers radiation at 1,064 nm, acts directly on malignant tissues causing thermonecrosis and vaporization. Tracheal and endobronchial prostheses have used as additional means for establishing and maintaining patent airway. These palliative therapies contribute to improving and maintaining the QOL of the patients. Methods of treatment for early superficial occult squamous cell carcinoma of the lung are bronchoscopic photodynamic therapy (PDT) and brachytherapy. PDT is used by photosensitizing agents (hematoporphyrin) that accumulate in malignant tissue and can be activated by a laser energy. Brachytherapy is technique for endobronchial irradiation involves the use of 192Ir. Both treatments are well effective for early superficial occult squamous cell carcinoma of the lung (CR rate is approximately 80%). They are safe and preserve pulmonary parenchyma
