US Patent No: 5554374
Skin preparation using nanospheres
Preparation for skin use comprising excipients, a drug carrier encapsulating beta-carotene and a
blend of UV-A and UV-B sun filters characterized in that: the drug carrier consisting of
nanospheres represents 3 to 6% by weight of the preparation; the proportion of UV-B filters is
greater than that of the UV-A filters; and the UV-B filters have a cinnamic structure. Application in
the treatment of melanic skin stains.
US Patent No: 5555885
Examination of breast tissue using time-resolved spectroscopy
A method of breast tissue examination using time-resolved spectroscopy includes the following
steps. A support that includes an input port and an output port separated by a selected distance is
positioned relative to the examined breast. Locations of the input and output ports are selected to
examine a tissue region of the breast. Light pulses of a selected wavelength and duration less than a
nanosecond are introduced into the breast tissue at the input port and detected over time at the
detection port. Signals corresponding to photons of detected modified pulses are accumulated over
time. Values of a scattering coefficient or an absorption coefficient of the examined breast tissue
are calculated based on the shape of the modified pulses. The examined breast tissue is
characterized based on the values of the scattering coefficient or the absorption coefficient.
Absorbing or fluorescing contrast agents may be introduced into the examined tissue. This method
may be used in conjunction with x-ray mammography, needle localization procedure or MRI
mammography.
US Patent No: 5556617
Composition providing a lasting cosmetic and/or pharmaceutical treatment of the upper epidermal layers
by topical application on the skin
A composition containing, in a suitable carrier, nanoparticles of one or more nonbiodegradable
polymer(s) encapsulating an oily phase which contains at least one active oil and/or at least one
carrier oil and/or at least one active ingredient in an active oil and/or a carrier oil. At least one
active ingredient is chosen from those with prolonged cosmetic and/or pharmaceutical activity. The
nanocapsules have a size of 100-1000 nm.
