浸潤性発育を示した後腹膜孤立線維性腫瘍の1例 [PDF]

, 2002
56歳女.悪性後腹膜孤立性線維性腫瘍であり, 主訴は腹部腫瘤触知で, 腹部CT及びMRI検査にて左腎下方に接して, Gerota筋膜に沿うように発育する境界不明瞭な腫瘤を認めた.手術所見では後腹膜腔にゼラチン状の腫瘍を認め, 下行結腸周囲の脂肪組織やGerota筋膜周囲の脂肪組織に浸潤していた.Gerota筋膜内への浸潤は認めなかったので左腎は温存した.病理組織像では間質の膠原線維は著明に増殖し, hemangiopericytoma様のくちばし状を呈する血管も豊富に認められた ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Resin infiltration revolution in minimal invasive treatment – A review

Journal of Global Oral Health
The concept of the resin infiltration technique emerged for the very 1 st time in 1970 for the conservative management of initial smooth surface caries. The precept of resin infiltration is to halt the non-cavitated enamel by obstructing the subsurface porosity with resin, so-called caries ...

Shaping Ti3C2 MXene Nanospheres for Precision Near‐Infrared Photothermal Therapy

Advanced Functional Materials, EarlyView.
In this study, we report producing spherical MXenes via fs laser fragmentation of Ti3C2 flakes in liquid medium. The nanoparticles demonstrated pronounced light absorption and high photothermal conversion efficiencies of 68% and 63% under heating with NIR‐I and NIR‐II lasers, respectively.

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

Advanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

Biomimetic Nanovaccine Integrating Dendritic Cell Exosomes with Tumor Cell Membranes for Sustained Prophylaxis Against Glioblastoma

Advanced Functional Materials, EarlyView.
We have developed DEX/GM, an all‐natural, personalizable hybrid vaccine designed by coating dendritic cell‐derived exosomes (DEX) onto tumor cell membranes (GM) for sustained prophylaxis against glioblastoma (GBM). ABSTRACT Glioblastoma (GBM), one of the most aggressive and lethal brain tumors, remains incurable with a poor clinical prognosis.

Study on invasion and migration of malignant glioma

Chinese Journal of Contemporary Neurology and Neurosurgery, 2018
Glioma shows diffuse infiltrative growth in the brain parenchyma. Even following the principle of "maximum safe resection", the residual tumor cells are resistant to adjuvant chemoradiotherapy and continue to invase and migrate in the brain tissue.
