1. Occurrence of tayras (Eira barbara Linnaeus, 1758) with anomalous coloration in Cerrado remnants in the state of São Paulo, Brazil
Resumo: Colorações anômalas são desordens geralmente de origem genética, em que a pigmentação do corpo é reduzida (hipopigmentação) ou excessiva (melanismo), em partes ou totalmente. Casos de hipopigmentação já foram documentados em muitos mamíferos neotropicais, incluindo a irara (Eira barbara Linnaeus, 1758). Nós expandimos os relatos de oco

2. Multifocal oral melanoacanthoma associated with Addison’s disease and hyperthyroidism: a case report
SUMMARY Oral melanoacanthoma is a mucocutaneous, pigmented, rare, benign, and probably reactive lesion. This paper reports for the first time in the literature a case of multifocal oral melanoacanthoma in a patient diagnosed with Addison’s disease and concomitant Graves’ disease with hyperthyroidism. The patient presented with oral pigmented lesions, whi

3. Influence of rosmarinic acid and Salvia officinalis extracts on melanogenesis of B16F10 cells
Melanin is a photoprotective skin pigment, and pathologies characterized by hypo or hyperpigmentation are common. New compounds that regulate melanogenesis are, therefore, opportune, and many natural products with this property, as polyphenols, have been described. Salvia officinalis L., Lamiaceae, is a widely used food spice that contains high amounts of ph

4. Avaliação de alterações orais em pacientes submetidos a transplante de medula óssea
Bone marrow transplantation (BMT) is currently the best therapeutic option for patients with hematologic diseases, solid tumors or autoimmune disorders. It is characterized by intravenous infusion of hematopoietic stem cells in order to restore marrow function. However, this procedure requires concomitant immunosuppression treatment, which favors the develop

5. Investigação citogenética em indivíduos com mosaico pigmentar do tipo Ito / Cytogenetic analysis in individuals with mosaic pigmentary of Ito type
O Mosaico pigmentar tipo Ito é uma alteração cutânea frequente, caracterizada por hipopigmentação da pele que, na maioria dos casos, segue o padrão linhas de Blaschko, geralmente associada a anomalias extracutâneas, sobretudo anomalias do Sistema Nervoso Central (SNC). Sugere-se que esse padrão decorre da presença e migração de duas linhagens cel

6. Avaliação de extratos de plantas da região amazônica quanto à atividade inibitória da tirosinase / Evaluation of extracts made from Amazon Forest plants and their Tyrosinase inhibitory activity
Dermatological disorders related to pigmentation result in cutaneous hyperpigmentation or hipopigmentation. Cosmetic and pharmaceutical products with despigmentant activity are used for the treatment of patients who have hyperpigmentation disorders. Nowadays, skin whitening agents are not to tally effective and safe, reason for intense researches in order to

7. Transmissible spongiform encephalopathy in the gray tremor mutant mouse.
Gray tremor (gt) is an autosomal recessive mutation in the mouse linked to caracul (Ca) on chromosome 15. The complex mutant phenotype includes pigmentation defects, tremor, seizures, hypo- and dysmyelination in central and peripheral nervous systems, spongiform encephalopathy, and early death. The heterozygote (+/gt) is phenotypically normal but develops a

8. The Microphthalmia Transcription Factor (Mitf) Controls Expression of the Ocular Albinism Type 1 Gene: Link between Melanin Synthesis and Melanosome Biogenesis
Melanogenesis is the process that regulates skin and eye pigmentation. Albinism, a genetic disease causing pigmentation defects and visual disorders, is caused by mutations in genes controlling either melanin synthesis or melanosome biogenesis. Here we show that a common transcriptional control regulates both of these processes. We performed an analysis of t

9. Mutations in Mcoln3 associated with deafness and pigmentation defects in varitint-waddler (Va) mice
Deafness in spontaneously occurring mouse mutants is often associated with defects in cochlea sensory hair cells, opening an avenue to systematically identify genes critical for hair cell structure and function. The classical semidominant mouse mutant varitint-waddler (Va) exhibits early-onset hearing loss, vestibular defects, pigmentation abnormalities, and

10. The genetic basis of epidermolysis bullosa simplex with mottled pigmentation.
Epidermolysis bullosa simplex (EBS) is a group of autosomal dominant skin diseases characterized by blistering, due to mechanical stress-induced degeneration of basal epidermal cells. It is now well-established that the three major subtypes of EBS are genetic disorders of the basal epidermal keratins, keratin 5 (K5) and keratin 14 (K14). Here we show that a
