Clinical assessment of fluorescence cystoscopy during transurethral bladder resection in superficial bladder cancer

The prognosis of superficial bladder cancer in terms of recurrence and disease progression is related to bladder tumor multiplicity and the presence of concomitant "plane" tumors such as high-grade dysplasia and carcinoma in situ.

Do liposome-binding constants of porphyrins correlate with their measured and predicted partitioning between octanol and water?

, 2002
We tested correlations between lipophilicity parameters and the partitioning of sensitizers into membranes. For this purpose we investigated 17 porphyrins and two chlorins having various chemical structures. Some of these compounds possess an amphiphilic

Pilot study on levels of chemical contaminants and porphyrins in Caretta caretta from the Mediterranean Sea

, 2014
Perfluorinated compounds (PFCs), synthetic musks compounds (SMCs), bisphenol A (BPA), para-nonylphenol (p-NP) and polybrominated diphenyl ethers (PBDEs) are known for their toxicity and ability to interfere with the endocrine system.

LTS3 gene controls light-independent chlorophyll biosynthesis in green algae Chlamydomonas reinhardtii

, 2010
The genetic control of light-independent chlorophyll biosynthesis in plant cells has been investigated using Chlamydomonas reinhardtii Lts3-mutants defective in dark chlorophyll biosynthesis on the stage before protochlorophyllide to chlorophyllide ...

Magnetic NTA -Based Affinity Mass Spectrometry for Rapid Detection of Indigenous Porphyrins

, 2013
紫質(Protoporphyrins)在身體代謝中扮演重要的角色，積累在腫瘤組織中的紫質為癌症的生物指標。然而，紫質在人體的癌症組織或細胞中含量很低，傳統偵測紫質方法不具足夠靈敏度以分析紫質。在此論文中，我們發展一個結合功能化磁性奈米粒子和質譜技術的新策略，能夠同時萃取和偵測紫質。 我們合成表面裝載三甘胺酸的功能化磁性奈米粒子，然後敖合鐵金屬離子，藉由鐵金屬離子和紫質中四個吡咯（pyrrole）環上的氮原子之間的親和力作用作為純化工具。使用紫質(protoporphyrins)標準品為模型 ...

Clinical value of fluorescence cystoscopy in the detection of superficial transitional cell carcinomas of the bladder

The prognosis of superficial bladder cancer in terms of local recurrence and transformation into invasive cancer is related to the multiplicity of tumor sites and the concomitant presence of "flat" tumours, such as dysplasia and carcinoma in situ.
