Solid Papillary Carcinoma with Invasion in the Male Breast: A Case Report and Literature Review

Introduction: Solid papillary carcinoma (SPC) accounts for approximately 1% of all breast cancer cases and occurs primarily in postmenopausal women. We report a rare SPC with invasion in the male breast. Case Presentation: A 73-year-old Japanese man presented with bloody nipple discharge and a palpable left breast mass. Mammography revealed a well-defined high-concentration mass. Ultrasonography scans demonstrated an intracystic 10 mm mass under the left nipple without enlarged axillary lymph nodes. A core needle biopsy revealed a ductal carcinoma with nuclear grade 1, which excluded an invasive carcinoma. Magnetic resonance imaging exhibited a 7 mm intense early enhancement in the left breast. A left mastectomy and sentinel lymph node biopsy were performed. The patient was diagnosed with pathological stage IA (T1b N0 M0) breast carcinoma, an invasive pure SPC type without neuroendocrine markers. The patient was treated with oral tamoxifen and survived without any recurrence for 12 months. Conclusion: Invasive SPC of the male breast may occur as a palpable mass or nipple discharge in older men and has a good prognosis

Effect of Curing Conditions on Physical Properties of Mortar Blended with Expansive Agent

Assuming precast concrete using expansion material, we will confirm the influence of curing conditions on the basic physical properties of mortar with regard to the free expansion coefficient, constraint expansion coefficient and strength, using two types of expansive materials widely used in Japan . As a result, it was confirmed that the higher the curing temperature, the higher the strength regardless of the addition of the expansion material. In addition, it was confirmed that both the free expansion coefficient and the constrained expansion ratio had an effect irrespective of the curing temperature of the lime type expansion material

日本-スウェーデン共同南極トラバース2007/2008 実施報告：I. 企画立案・事前準備と科学研究成果の概要

南極地域観測第Ⅶ期5か年計画に基づき，2007/2008 年の南極の夏期シーズンに，国立極地研究所を中心とした研究グループは，スウェーデンの研究者グループと共同で，東南極内陸域のドロンイングモードランド地域の内陸部の氷床環境調査を実施した．本報告は，現地調査前に5年間を費やした研究計画の企画検討の経過や行った事前準備と，現地野外観測を終了した後の6年間に得られた研究成果の概要をまとめるものである．本プロジェクトの調査により，南極内陸高原部の氷床環境の時空間分布について，多くの科学的知見が明らかになった．本報告はその概要を報告する．現地調査の実行の経過は別途の報告に記述する．In the seventh five-year plan of the Japanese Antarctic Research Expedition, a group of Japanese scientists (led by the National Institute of Polar Research) together with a group of Swedish scientists, conducted field surveys to better understand the glaciology of the ice sheet in Dronning Maud Land, East Antarctica, during the 2007/2008 austral summer season. This paper reports on the planning and field preparations, and outlines the scientific achievements of the field expedition. We have gained numerous new scientific insights on the spatio-temporal distribution of the ice sheet environment in the inland plateau. Here, we provide an overview of the new knowledge gained

Mechanical design of the optical modules intended for IceCube-Gen2

IceCube-Gen2 is an expansion of the IceCube neutrino observatory at the South Pole that aims to increase the sensitivity to high-energy neutrinos by an order of magnitude. To this end, about 10,000 new optical modules will be installed, instrumenting a fiducial volume of about 8 km3. Two newly developed optical module types increase IceCube’s current sensitivity per module by a factor of three by integrating 16 and 18 newly developed four-inch PMTs in specially designed 12.5-inch diameter pressure vessels. Both designs use conical silicone gel pads to optically couple the PMTs to the pressure vessel to increase photon collection efficiency. The outside portion of gel pads are pre-cast onto each PMT prior to integration, while the interiors are filled and cast after the PMT assemblies are installed in the pressure vessel via a pushing mechanism. This paper presents both the mechanical design, as well as the performance of prototype modules at high pressure (70 MPa) and low temperature (−40∘C), characteristic of the environment inside the South Pole ice
