The present invention provides non-invasive methods for detecting, monitoring, and diagnosing skin disease and pathological skin states such as irritated skin and psoriasis. The methods include using tape stripping to analyze expression in epidermal samples, of one or more skin markers. In illustrative examples, the tape stripping is performed using pliable tape that has a rubber adhesive. Furthermore, the present invention provides methods for predicting and monitoring response to therapy for a skin disease, such as psoriasis or dermatitis. Finally, the methods can include the use of a microarray.

The leading cause of graft failure is the subsequent development of intimal hyperplasia, which represents a response to injury that is thought to involve smooth muscle proliferation, migration, phenotypic modulation, and extracellular matrix (ECM) deposition. Surgical techniques typically employed for vein harvest—stretching the vein, placing the vein in low pH, solutions, and the use of toxic surgical skin markers—are shown here to cause injury. The invention therefore provides for non-toxic surgical markers than also protect against stretch-induced loss of functional viability, along with other additives. Devices and compositions for reducing physical stress or protecting from the effects flowing therefrom, also are provided.

The present invention provides non-invasive methods for isolating an miRNA molecule from an epidermal sample, as well as detecting, monitoring, and diagnosing skin disease and pathological skin states such as irritated skin and psoriasis. The methods include using tape stripping to obtain the miRNA from epidermal samples, and may be used to further analyze expression of one or more skin markers. In illustrative examples, the tape stripping is performed using pliable tape that has a rubber adhesive. Furthermore, the present invention provides methods for predicting and monitoring response to therapy for a skin disease, such as psoriasis or dermatitis. Finally, the methods can include the use of a microarray.

A multi-density skin marker for medical imaging exams is provided. The skin marker contains a multi-density imaging body. In one embodiment, a multi-density skin marker includes a marker substrate and a multi-density imaging body supported by the marker substrate. The multi-density imaging body comprises a first portion having a first radiographic density and a second portion having a second radiographic density. The two radiographic densities differ, such that a radiographic image of the multi-density skin marker comprises a plurality of shades.

Automated spine localizing, numbering and autoprescription system enhances correct location of diseased or injured tissue, even allow multi-spectral diagnosis. Externally located this tissue is facilitated by an integrated self adhesive spatial reference and skin marking system that is designed for a variety of modalities to include MRI, CT, SPECT, PET, planar nuclear imaging, radiography, XRT, thermography, optical imaging and 3D space tracking. The device ranges from a point localizer to a more multifunctional and complex grid / phantom system. The specially designed spatial reference(s) is affixed to an adhesive strip with corresponding markings so that after applying the unit to the skin / surface and imaging, the reference can be removed leaving the skin appropriately marked. The localizer itself can also directly adhere to the skin after being detached from the underlying strip. A spine autoprescription process performs image analysis that is able to identify vertebrae and discs even in the presence of abnormalities.

A surgical skin marker has a handle body and a removably attached marking tip that is provided in a protective sterilized bag. After a single use, the marking tip can be removed and discarded. A new marking tip can be attached for a subsequent surgical procedure or treatment. Such a marker can help maintain a sterile surgical environment while minimizing waste and costs.

The present invention provides methods for characterizing a skin sample of a subject as belonging to an age range by analyzing nucleic acid or protein molecules obtained from the subject. The methods include analyzing expression or mutations in epidermal samples, of one or more skin markers. The methods can include the use of a microarray to analyze gene or protein profiles from a sample and compare them with a known skin age index. Therapeutic and cosmetic formulations are also provided herein.

The present invention provides methods for diagnosing melanoma and / or solar lentigo in a subject by analyzing nucleic acid molecules obtained from the subject. The present invention also provides methods for distinguishing melanoma from solar lentigo and / or dysplastic nevi and / or normal pigmented skin. The methods include analyzing expression or mutations in epidermal samples, of one or more skin markers. The methods can include the use of a microarray to analyze gene or protein profiles from a sample

The invention discloses a thoracic tumor radiotherapy facilitating combined type positioning rack device. According to the upper portion of the thoracic tumor radiotherapy facilitating combined type positioning rack device, a support plate and armrests are arranged at the top; two side baffles are connected to both sides of an inclined plate; a pillow box is arranged in the middle of the inclined plate, the lower edges of the pillow box and the inclined plate are aligned; a soft plastic material base is arranged at the bottom. The thoracic tumor radiotherapy facilitating combined type positioning rack device can avoid random deviation of skin markers and ensure high repeatability and consistency of the skin positioning marker and is applied to limiting and fixing the thoracic position of a thoracic tumor patient during radiotherapy.

A one-time skin marking system and method. The system includes a marking implement with a hollow body portion and a marking tip extending therefrom. When liquid contained in the hollow body portion is introduced to the tip, the marking implement is used to mark a surgical site and then discarded. The marking liquid is indelible and has a volume not greater than an amount substantially equal to the liquid carrying capacity of the marking tip.

The invention relates to an invisible skin marker based on a rare earth up-conversion material, the marker is mainly prepared from an amine polymer modified manganese, ytterbium and erbium doped sodium yttrium tetrafluoride (NaYF4: Yb, Er, Mn) rare earth up-conversion material and a solvent, when the marker is coated or sprayed on the surface of the skin of a specific target, the marker is invisible under visible light, and the marker can be applied to the skin of the specific target. Manual removal of the marker can be avoided; and the marker displays strong fluorescence under near-infrared exciting light, has good anti-interference performance and washing resistance, and can provide a basis for identifying and recognizing suspects. The problems that part of existing markers do not have mark concealment and are not easy to mark for a long time, and the mark fluorescence color is easily interfered by the environment are effectively solved. The marker provided by the invention has good stability, anti-interference performance and relatively strong washing resistance.

The invention relates to the technical field of tactile sensors, in particular to a tactile fingertip sensor and an operating system and a data processing method.The tactile fingertip sensor comprises a tactile skin, a mark array sticker and a monocular camera, the mark array sticker is pasted on the inner side of the tactile skin, and the bottom of the tactile skin and the bottom of the tactile fingertip sensor form a hollow cavity; the monocular camera is installed at the bottom of the touch fingertip sensor and located in the hollow cavity, and the vision field of the monocular camera covers the inner side of the touch skin. According to the touch fingertip sensor disclosed by the invention, when a mechanical finger wearing the sensor touches an object, the sensor shoots an internal mark array image through the monocular camera, inputs the internal mark array image to the upper computer for image processing and data analysis, and finally converts the internal mark array image into various touch information; comprise the deformation condition of the contact surface, the size and direction of pressure at each marked position, contact torque and the like. By means of the design, contact in different directions can be sensed, distributed touch information is provided, and it is guaranteed that the sensor is compact in structure and light in weight.
