We demonstrate the application of terahertz pulse imaging (TPI) in reflection geometry for the study of skin tissue and related cancers both in vitro and in vivo. The sensitivity of terahertz radiation to polar molecules, such as water, makes TPI suitable for studying the hydration levels in the skin and the determination of the lateral spread of skin(More)
The feasibility of using terahertz pulsed imaging to map margins of exposed breast tumors was investigated by imaging 22 excised human breast tissue specimens with carcinoma excised from 22 women (mean age, 59 years; range, 39-80 years). The study was approved by the local ethics research committee, and informed consent was obtained from all patients. The(More)
Terahertz pulse imaging has been used for the first time to study basal cell carcinoma ex vivo, the most common form of skin cancer. This noninvasive technique uses part of the electromagnetic spectrum in the frequency range 0.1-2.7 THz. A total of 21 samples were imaged; the study was performed blind and results were compared to histology. Each image(More)
Terahertz (THz) radiation lies between the infrared and microwave regions of the electromagnetic spectrum. Advances in THz technology have opened up many opportunities in this scientifically and technologically important spectroscopic region. The THz frequency range excites large amplitude vibrational modes of molecules as well as probing the weak(More)
Sera from 17 patients with bullous pemphigoid identified a range of polypeptides of relative molecular mass (Mr) 240,000, 230,000, 190,000, 180,000, 120,000 and 100,000 from extracts of SCaBER cells, cultured human keratinocytes or human epidermis, using an immunoblotting technique. The pattern of polypeptides was characteristic for the patient serum and(More)
A series of novel 2-arylbenzoxazoles that upregulate the production of utrophin in murine H2K cells, as assessed using a luciferase reporter linked assay, have been identified. This compound class appears to hold considerable promise as a potential treatment for Duchenne muscular dystrophy. Following the delineation of structure-activity relationships in(More)
Extramammary Paget's disease (EMPD) is a rare cutaneous malignancy, which usually occurs in the elderly. Wide local excision is the recommended treatment, although this may not always be feasible. We report our experience of EMPD treated by radiotherapy in five patients. The radiotherapy was well tolerated in each case, and there were no signs of recurrence(More)
The sebum excretion rate from forehead skin was measured in 44 patients with classic seborrhoeic dermatitis and 200 control subjects. The mean excretion rate was normal in the 29 men with seborrhoeic dermatitis and significantly reduced in the 15 women with the disease. This study showed that seborrhoeic dermatitis is not usually associated with seborrhoea,(More)
