Understanding the disparate mixing patterns between quarks and leptons is one of the major challenges in particle theory today. I discuss some of the ways to understand this difference within the seesaw framework using new symmetries of quarks and leptons. After a brief introduction to the various types of seesaw formulae, proposals for understanding large solar and atmospheric mixings for the ...

proper differentiation between acral malignant melanoma and benign pigmented lesions like melanocytic nevi is of great value. to avoid unnecessary biopsies, dermatoscopy has been introduced as a non-invasive modality and has improved the clinical diagnostic accuracy in recent decades. we aimed to describe dermoscopic patterns of acral pigmented lesions of patients in the clinic of dermatology i...

Pigmentary mosaicisms are nevoid diseases characterized by the presence on the skin of hyperor hypopigmented macules with particular clinical patterns. Occasionally they show association with extracutaneous defects that may alter the normal development of the affected person. We present a compilation of all the cases of pigmentary mosaicism evaluated at our Department in the past decade (Dermat...
