Background: Tinea corporis (TC) is a common fungal infection affecting 20%-25% of the global population. Though diagnosing TC is straightforward, treatment has become challenging due to the use of certain medications and lack of follow-up, leading to resistance. Andrea et al.

- The study compares a tri-partite scoring system (TPSS) used in teledermatology with the International Contact Dermatitis Research Group (ICDRG) grading, which is the standard for interpreting patch test results.
- The TPSS showed high sensitivity and specificity, with excellent agreement between two investigators' scoring methods, indicating it is a reliable alternative.
- The findings suggest that TPSS can effectively reduce patient visits by 50%, making it a practical option especially during situations like the COVID-19 pandemic.

Background: Hand eczema (HE), foot eczema (FE), and hand-foot eczema (HFE) manifest on exposure to various agents in day-to-day life or in occupations or both.
Objectives: The objectives of this study were to identify pattern of allergens causing HE, FE, and HFE and to identify multiple and concurrent contact allergies.
Materials And Methods: A study was conducted from October 2013 to August 2015 which included 190 patients.

Article Synopsis
- * The acquired periungual fibrokeratoma is a specific variant, characterized by a "garlic clove" shape, and is thought to have a traumatic origin, mainly occurring on fingers and toes.
- * A case study of a 29-year-old man with a fibrokeratoma on his left little finger was reported, with surgical excision confirming the diagnosis, marking it as the first documented instance of this type on a little finger.
C-phycocyanin, a natural food colorant, is gaining importance worldwide due to its several medical and pharmaceutical applications. In the present study, aqueous two-phase extraction was shown to be an attractive alternative for the downstream processing of C-phycocyanin from Spirulina platensis. By employing differential partitioning, C-phycocyanin selectively partitioned to the polymer rich (top) phase in concentrated form and contaminant proteins to the salt rich (bottom) phase.

A new aqueous two phase system comprising polyethylene glycol and xanthan is reported together with its phase diagram. The phase composition of the bottom phase did not vary (PEG 1.6-1.
View Article and Find Full Text PDFElectrokinetic demixing of aqueous two-phase polymer/salt systems is demonstrated, resulting in significant enhancement in demixing rates by about 1-4-fold. The effect of field polarity, field strength, volume ratio, and phase composition on phase demixing has been studied. Further the influence of these parameters on phase demixing could be explained based on the hydrodynamic flow-electroosmotic flow (HEF) model.
