Dysregulation of neuropeptides may play an important role in aging-induced impairments. Among them, pituitary adenylate cyclase activating polypeptide (PACAP) is a potent cytoprotective peptide that provides an endogenous control against a variety of tissue-damaging stimuli. We hypothesized that the progressive decline of PACAP throughout life, and the well-known general cytoprotective effects of PACAP lead to age-related pathophysiological changes in PACAP deficiency, supported by the increased vulnerability to various stressors of animals partially or totally lacking PACAP...

Adult wild-type mice are not supposed to be proper models for ultraviolet radiation (UVR)-induced melanoma since melanocytes are confined to hair follicles and cannot be sufficiently reached by UVR. On the other hand, in mutated mouse models used for melanoma research limitations, including an altered immune system and selection of affected pathways, lead to tumors phenotypically quite different from naturally occurring melanomas. We compared the distribution of epidermal melanocytes in UVR and not-UVR-exposed wild-type C57BL/6 mice...

BACKGROUND: Podoconiosis (also known as endemic, non-filarial elephantiasis) affects about 4 million subsistence farmers in tropical Africa. Poor awareness of the condition and inadequate evidence for the efficacy of treatment mean that no government in an endemic country yet offers lymphoedema management for patients with podoconiosis. Among patients with filarial lymphoedema, trials suggest that limb care is effective in reducing the most disabling sequelae: episodes of acute dermatolymphangioadenitis...

OBJECTIVE: Research documents that even subtle changes in visible skin condition affect perceptions of age, health, and attractiveness. There is evidence that hair quality also affects the assessment of physical appearance, as variations in hair diameter, hair density, and hair style have systematic effects on perception. Here, we consider combined effects of hair color and skin color on the perception of female physical appearance. METHODS: In two experiments, we digitally manipulated facial skin color of lightly-pigmented, young women, both between-subjects (Experiment 1) and within-subjects (Experiment 2), and investigated possible interactions with hair color in regard to age, health, and attractiveness perception...

BACKGROUND: Early detection of several skin-related neglected tropical diseases (skin NTDs)-including leprosy, Buruli ulcer, yaws, and scabies- may be achieved through school surveys, but such an approach has seldom been tested systematically on a large scale in endemic countries. Additionally, a better understanding of the spectrum of skin diseases and the at-risk populations to be encountered during such surveys is necessary to facilitate the process. METHODS: We performed a school skin survey for selected NTDs and the spectrum of skin diseases, among primary schoolchildren aged 5 to 15 in Côte d'Ivoire, West Africa...

AIM: Non-melanoma skin cancer (NMSC) is the most commonly diagnosed and most costly cancer in Australasia. Cutaneous squamous cell carcinoma (cSCC) accounts for approximately 25% of NMSC. Despite this, reporting of cSCC is not mandatory in Australasia. This creates difficulties in planning, resourcing and improving outcomes in cSCC. Previous studies in New Zealand have lacked data on ethnicity. The aim of this study was to define the incidence and demographics of cSCC diagnosed in Northland, New Zealand, including data on ethnicity...

BACKGROUND: Cutaneous melanoma incidence may be modestly elevated in people with HIV (PWH) versus people without HIV. However, little is known about the relationship of immunosuppression, HIV replication, and antiretroviral treatment (ART) with melanoma risk. METHODS: PWH of white race in the North American AIDS Cohort Collaboration on Research and Design were included. A standardized incidence ratio (SIR) was calculated comparing risk with the white general population, standardizing by age, sex, and calendar period...

Psoriasis is characterized by excessive cell proliferation, angiogenesis, and regions of hypoxia. Hypoxia stimulates production of hypoxia inducible factors (HIFs) such as HIF1α. The aim of the present study is to investigate the possible role of HIF1α in pathogenesis of psoriasis and to correlate its expression with angiogenesis and proliferation in involved and uninvolved skin in patients with plaque psoriasis using CD34 and Ki-67. The current study was performed on 40 skin specimens of patients presented with chronic plaque psoriasis both involved and uninvolved together with 40 specimens from age- and sex-matched healthy volunteers as a control group...

Fabry disease is an X-linked genetic deficiency in the alpha-galactosidase enzyme resulting in intracellular accumulation of glycosphingolipids and multisystem organ dysfunction. Typically 50% of males and 20% of affected females have renal involvement, ranging from proteinuria or reduced renal function, renal parapelvic cysts and progressive renal disease ultimately requiring transplantation or dialysis. The phenotypic presentation of Fabry disease is incredibly varied and will even vary between family members with the same confirmed genetic mutation...

REVIEW
Sharon A Savage
Studies of rare and common illnesses have led to remarkable progress in the understanding of the role of telomeres (nucleoprotein complexes at chromosome ends essential for chromosomal integrity) in human disease. Telomere biology disorders encompass a growing spectrum of conditions caused by rare pathogenic germline variants in genes encoding essential aspects of telomere function. Dyskeratosis congenita, a disorder at the severe end of this spectrum, typically presents in childhood with the classic triad of abnormal skin pigmentation, nail dystrophy, and oral leukoplakia, accompanied by a very high risk of bone marrow failure, cancer, pulmonary fibrosis, and other medical problems...
