- International journal of cancer
- 20 December 2003
NIR Raman spectroscopy provides significant potential for the noninvasive diagnosis of lung cancers in vivo based on the optic evaluation of biomolecules, according to the results of this exploratory study. Expand
Real-time Raman spectroscopy for in vivo skin cancer diagnosis.
It is established that real-time Raman spectroscopy can be used to distinguish malignant from benign skin lesions with good diagnostic accuracy comparable with clinical examination and other optical-based methods. Expand
Automated Autofluorescence Background Subtraction Algorithm for Biomedical Raman Spectroscopy
An improved automated algorithm for fluorescence removal has been developed based on modified multi-polynomial fitting, but with the addition of a peak-removal procedure during the first iteration, and a statistical method to account for signal noise effects. Expand
Efficacy of once‐daily treatment regimens with calcipotriol/betamethasone dipropionate ointment and calcipotriol ointment in psoriasis vulgaris
- K. Kragballe, K. Noerrelund, +7 authors L. Persson
- The British journal of dermatology
- 1 June 2004
Background A two‐compound ointment containing calcipotriol 50 µg g−1 and betamethasone dipropionate 0·5 mg g−1 has recently been shown to be an effective treatment for psoriasis.
Detection and Analysis of Irregular Streaks in Dermoscopic Images of Skin Lesions

- Mathematics, Computer Science
- IEEE Transactions on Medical Imaging
- 14 January 2013
The previous algorithm to identify the absence or presence of streaks in a skin lesions is extended, by further analyzing the appearance of detected streak lines, and performing a three-way classification for streaks, Absent, Regular, and Irregular, in a pigmented skin lesion. Expand
Raman spectroscopy for optical diagnosis in normal and cancerous tissue of the nasopharynx—preliminary findings
Raman spectroscopy (RS), which can detect molecular changes associated with cancer, was explored as a means of distinguishing normal and cancerous nasopharyngeal tissue.
Raman spectroscopy of in vivo cutaneous melanin.
- Zhiwei Huang, H. Lui, X. Chen, Abdulmajeed Alajlan, D. McLean, H. Zeng
- Chemistry, Medicine
- Journal of biomedical optics
- 1 November 2004
The ability to acquire these unique in vivo melanin signals suggests that Raman spectroscopy may be a useful clinical method for noninvasive in situ analysis and diagnosis of the skin. Expand
Full range characterization of the Raman spectra of organs in a murine model.
The results suggest that organ specific Raman probe design and specific data processing strategies are required in order to get the most useful information. Expand
A randomized bilateral vehicle-controlled study of eflornithine cream combined with laser treatment versus laser treatment alone for facial hirsutism in women.
- I. Hamzavi, E. Tan, J. Shapiro, H. Lui
- Journal of the American Academy of Dermatology
- 1 July 2007
It is demonstrated that the addition of eflornithine to laser hair removal results in a more rapid and complete reduction of unwanted facial hair in women when the combination is used for up to 6 months. Expand
