BACKGROUND Lymph node dissection is often performed as a part of surgical treatment for breast cancer and malignant melanoma to prevent malignant cells from traveling via the lymphatic system. Currently little is known about postoperative lymphatic drainage pattern alterations. This knowledge may be useful for management of recurrent cancer and prevention of breast cancer related lymphedema. We...
Sentinel lymph node biopsy (SLNB) is a minimally invasive method that was developed to stage the regional lymphatics of patients with cutaneous melanoma. Many studies performed worldwide have shown that SLNB is a feasible method to stage the cervical lymphatics in patients with head and neck squamous cell carcinoma (HNSCC). The accuracy of SLNB in patients with HNSCC is currently under investig...
background and objectives: involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. in the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. the aim of this study was determination of the relationship between the size of col...
Ligand-directed targeting of lymphatic vessels uncovers mechanistic insights in melanoma metastasis.
Metastasis is the most lethal step of cancer progression in patients with invasive melanoma. In most human cancers, including melanoma, tumor dissemination through the lymphatic vasculature provides a major route for tumor metastasis. Unfortunately, molecular mechanisms that facilitate interactions between melanoma cells and lymphatic vessels are unknown. Here, we developed an unbiased approach...
A 46-year-old woman was examined because of cellulitis of the right leg, which she said had been swollen for 30 years. This is lymphedema, a condition that results from obstruction or abnormalities in the lymphatic system (eg, hypoplasia or lymphangiectasia). It may also be caused by filariasis, which is common in the tropics. Lymphedema may be iatrogenic following irradiation or surgery for br...
Optical energy can trigger a variety of photochemical processes useful for therapies. Owing to the shallow penetration of light in tissues, however, the clinical applications of light-activated therapies have been limited. Bioluminescence resonant energy transfer (BRET) may provide a new way of inducing photochemical activation. Here, we show that efficient bioluminescence energy-induced photod...
this study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. in this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (galt) in chicken were selected. one hundred an...
Optically active nanomaterials promise to advance a range of biophotonic techniques through nanoscale optical effects and integration of multiple imaging and therapeutic modalities. Here, we report the development of porphysomes; nanovesicles formed from self-assembled porphyrin bilayers that generated large, tunable extinction coefficients, structure-dependent fluorescence self-quenching and u...
The pulmonary lymph flow, m e d by our previously published method, is reported in ten dogs after irradiation to anterior mediastinal portals which included the medial one-thud of both lungs. In group A (six dogs) the lymph flow of the lung was measured immediately after the course of radiation and in group B (four dogs) a period of about five months elapsed. Our results show that the lymph flo...
We demonstrate the ability to non-invasively and quantitatively image lymphatic architecture and contractile function using dynamic near-infrared (NIR) fluorescence imaging with injection of indocyanine green in normal and transgenic mice. Unlike normal mice, which showed well defined lymphatic drainage patterns and orthograde propagation of contraction waves, we observed tortuous and mispatter...
