Cell Projection Volume Rendering.

The Journal of the Institute of Image Information and Television Engineers, 1999
We propose a new volume rendering technique called cell projection, which is a combination both forward and backward projections. It renders high-quality images as well as raycasting. Non-empty cells are forward projected onto the projection plane from each pixel within the projected region of the cell, a ray is back-projected to the cell, and the ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

3D ultrasound reconstruction based on free hand acquisitions with motion estimation [PDF]

International Journal of Electronics and Telecommunications
We present a method for motion artifacts reduction during 3D volume reconstruction of free hand 2D ultrasound sequences. Motion estimation and additional filtering improves quality of free hand 3D ultrasound data resulting in improved imaging ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Particle-based Volume Rendering

Transaction of the Visualization Society of Japan, 2007
本論文では，ボリュームデータを不透明な発光粒子の集合という離散モデルとして表現することによりアルファ合成およびソート計算を必要としない粒子ベースボリュームレンダリング法を提案する．本手法では，不透明属性を持つ発光粒子を，確率論的アプローチにより，利用者が与える伝達関数から推定される粒子密度分布に応じて発生する．そして，それらを画像面に投影することによってレンダリングを行う．さらに，本手法では，画像投影処理において粒子ごとの深さ情報の比較だけが必要とされるが，粒子半径を比較的大きく設定する，つまり各画素に1個程度の粒子が投影される場合には，ボリュームレンダリングの特徴である半透明表示が困難となる．このため，一つの画素に対して，複数の粒子が投影されるようにサブサンプリング処理を行い ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Real-time external labeling layout algorithm for Direct Volume Rendering

Revista Cubana de Informática Médica, 2016
Illustrations used in technical and scientific texts often employ labels to correlate the graphic elements and their textual descriptions. Researchers have proposed several algorithms to determine the layout of the annotations on images rendered at ...
