4 results about "Tinea capitis" patented technology

The invention discloses a tinea capitis detection method and device based on multi-channel fluorescence sensing, and the method comprises the steps: transmitting composite wave band excitation light to a to-be-detected scalp region, collecting a fluorescence spectrum signal and a short wave infrared diffuse reflection signal, and constructing a multi-mode optical signal; according to the environment baseline signal, adaptive filtering processing based on variational mode decomposition, blind source separation and correction are carried out on the multi-mode optical signal, and a net fluorescence signal is generated; spectral data cube construction and decomposition are carried out on the net fluorescence signals, and RGB three-color fluorescence intensity values are extracted; generating a fluorescence distribution lattice diagram according to the RGB three-color fluorescence intensity value, converting the fluorescence distribution lattice diagram into a recurrence plot matrix, and identifying a fungal infection area; performing super-pixel segmentation and spectral clustering on the fungal infection region to obtain multi-scale texture features and heterogeneity sub-region labels; and identifying the tinea capitis type and the infection degree grade based on the recurrence plot matrix, the multi-scale texture features and the heterogeneity sub-region labels. The efficiency and accuracy of tinea capitis detection can be effectively improved.

Methods and compositions for treating, preventing and controlling fungal infections, including superficial infections, using compounds of the β-carboline class are disclosed. Pharmaceutical compositions comprising β-carbolines alone, or in combination with therapeutically effective amounts of an antimycotic, are administered to a subject to treat or prevent a superficial fungus infection such as those caused by fungi selected from the Candida or Trichophyton genus, infections such as dermatomycosis, diaper rash (yeast dermatitis), athletes' foot (tinea pedis), jock itch (tinea cruris), ringworm (tinea capitis) and cutaneous candidiasis. Methods of treating, preventing or controlling fungal infections in a plant are also disclosed, wherein a composition comprising an agriculturally acceptable amount of a β-carboline and a fungicide is administered to the plant and / or the locus of the plant, β-carbolines having the following formula are preferred. (Formula I).
