Drug-induced pigmentation

Pigment International, 2022
Around 10% to 20% of all cases of acquired hyperpigmentation are drug-induced. The underlying pathogenesis for drug-induced pigmentation includes melanin accumulation, drug accumulation, toxic effects on melanocytes, and hypersecretion of ...

Diagnostic findings in Various Cutaneous Hypopigmented Disorders: A Scoping Review [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Medical conditions can cause the skin to become hypopigmented or depigmented, mainly due to decreased production of melanin. Hypomelanosis is mainly benign and rarely malignant.

Hypopigmented macules following quality-switched 1064 nm laser hair removal: A retrospective study

Journal of Dermatology and Dermatologic Surgery, 2020
Introduction: Laser hair removal (LHR) is a common procedure in dermatology. LHR using quality-switched (QS) 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) is very popular in our community despite lack of sufficient evidence on its efficacy and

Depigmentation therapies in vitiligo

Indian Journal of Dermatology, Venereology, and Leprology, 2012
Depigmentation therapy in vitiligo is an option in those with extensive vitiligo who have failed to respond to medical therapy and have obvious cosmetic disfigurement due to intervening patchy pigmented areas. Various aspects of this therapy such as the cost, treatment time, course, permanency of depigmentation, side effects, and the possibility of ...

ntimelanogenesis effect of ethyl acetate extract of avocado seeds (Persea americana Mill.) on B16F10 melanoma cells [PDF]

Journal of Pharmacy & Pharmacognosy Research
Context: Hyperpigmentation is frequently associated with ultraviolet radiation exposure. Natural tyrosinase inhibitors, such as catechin from avocado seeds (Persea americana Mill.), are increasingly studied due to their antioxidant and tyrosinase ...

The association between neural crest‐derived glia and melanocyte lineages throughout development and disease

Developmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient cell population that emerges from the dorsal neural tube during neurulation and migrates extensively throughout the embryo. Among their diverse derivatives, glial cells (such as Schwann and satellite ganglionic cells) and melanocytes represent two major lineages. In vitro studies suggested they share a common

Role of SoxE transcription factors in development and disease

Developmental Dynamics, EarlyView.
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Quantitative Assessment of Visible Nigrosome‐1 in Patients with Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background The nigrosome‐1 (N1) sign on susceptibility‐weighted imaging (SWI) typically disappears in Parkinson's disease (PD), though some patients can show uni−/bilaterally preserved N1. Objective Investigating whether visible nigrosomes in PD patients differ from those of healthy subjects (HC). Methods Forty‐eight PD and 35 HC underwent 3 T‐

Evaluation of Histologically and Histochemically Proven Cases of Vitiligo and its Correlation with CD4+ and CD8+ Lymphocyte Counts using Flow Cytometry [PDF]

Journal of Clinical and Diagnostic Research, 2017
Introduction: Vitiligo is an acquired cutaneous disorder characterized by progressive and selective destruction of melanocytes from the epidermis. Autoimmunity is strongly implicated in its pathogenesis.

“White and Clear” (WaC): A tunable hydrophilic tissue clearing strategy for multi‐species 3D imaging

VIEW, EarlyView.
Optical tissue clearing methods help scientists make tissues transparent to image structures deep inside organs in 3D, but many existing techniques are limited in performance and difficulty. In this study, we developed an optimized clearing method called WaC (White and Clear), which improves upon existing techniques by combining efficient tissue ...
