[A Case of Chemotherapy with Low-Dose Paclitaxel and Bevacizumab for Elderly Recurrent Breast Cancer Patient].

An 86-year-old woman underwent mastectomy with sentinel lymph node biopsy for cStage ⅡA breast cancer. The subtype of tumor was triple negative breast cancer. Pulmonary metastasis was found 1 month after surgery.

Structural mechanism and photoprotective function of water-soluble chlorophyll-binding protein.

A water-soluble chlorophyll-binding protein (WSCP) is the single known instance of a putative chlorophyll (Chl) carrier in green plants. Recently the photoprotective function of WSCP has been demonstrated by EPR measurements; the light-induced singlet-oxygen formation of Chl in the WSCP tetramer is about four times lower than that of unbound Chl. This paper describes the crystal structure of the WSCP-Chl complex purified from leaves of Lepidium virginicum (Virginia pepperweed) to clarify the mechanism of its photoprotective function.

[A case of bone metastases from carcinoma of the lung demonstrating increased uptake of 99mTc-ECD].

A 48-year-old man with carcinoma of the lung had loss of consciousness during radiation therapy and underwent 99mTc-ethyl cysteinate dimer (99mTc-ECD) SPECT to evaluate brain tumor seen on CT scan. Incidentally 99mTc-ECD SPECT imaging showed intense accumulation in the frontal and occipital bone. The tumor in the occipital bone had been histologically proven to be a metastasis from carcinoma of the lung.

Crystallization and preliminary X-ray diffraction studies of cytochrome c6 from Porphyra yezoensis.

Cytochrome c(6) from the red alga Porphyra yezoensis has been purified and crystallized by the sitting-drop vapour-diffusion method. Two different crystal forms, tetragonal and orthorhombic, were obtained. The tetragonal crystals belong to space group P4(1)2(1)2 or P4(3)2(1)2, with unit-cell dimensions a = 49.

Number of lymph node metastases influences survival in patients with thoracic esophageal carcinoma: therapeutic value of radiation treatment for recurrence.

We retrospectively investigated whether the number of involved lymph nodes and the radiation therapy for recurrence affect survival in patients with thoracic esophageal carcinoma. Eighty-nine patients underwent surgical resection and reconstruction for thoracic esophageal squamous cell carcinoma beyond the mucosal layer. Patients were classified into three groups: group 1 comprised 40 patients without lymph node involvement; group 2 comprised 34 patients with 1-3 positive nodes; and group 3 comprised 15 patients with > or = 4 involved lymph nodes.
