The present study was undertaken to study the sunscreen activity of herbal formulation. There is no evidence of the sun protection factor (SPF) studies on essential oil of Calendula flowers (Calendula officinalis L., Asteraceae). The study investigates the in vitro SPF by ultraviolet specrtophotometry method of Calendula flower oil in a cream formulation. Calendula oil was isolated by Clavenger...

Background: Recreational sun exposure has been associated with melanoma prevalence, and tourism settings are of particular interest for skin cancer prevention. Effective, affordable, and geographically flexible interventions to promote sun protection are needed. Objective: The aim of this study was to describe the protocol for a definitive randomized controlled trial (RCT) evaluating a smartpho...

BACKGROUND Pediatric visits during summer months may be especially opportune times for sun protection counseling for children and their parents. Few data exist on the extent of such counseling. OBJECTIVE To begin to assess this, we surveyed practicing Massachusetts pediatricians to examine current attitudes and practices of sun protection counseling. DESIGN AND SETTING Surveys mailed to Mas...

Background: Sun exposure, particularly during childhood, is an important contributing factor in developing melanoma later in life. Objective: To develop a family-centered, self-reinforcing sun protection educational intervention that supports pediatrician’s anticipatory guidance and assess the feasibility of delivering the sun protection intervention in pediatrician offices, and use of sun prot...

This paper aims to encapsulate into solid lipid nanoparticles a mixture of two bioactive compounds, a photoprotective agent and an antioxidant compound. The co-encapsulation effect of octocrylene sunscreen and flavonoid (luteolinon) has been studied on the specific properties like antioxidant activity, sun protection factor and photostability. Using the high preasure homogenization technique li...

OBJECTIVE An analysis of Canadian survey data was performed to identify independent predictors of different protective behaviours and of their use in combination. METHODS Data from light-skinned respondents of the 1996 National Survey on Sun Exposure & Protective Behaviours who spent 30+ minutes per day of their leisure time in the sun (N = 1,027) were analyzed. Multivariable logistic regress...

Outdoor workers are at a higher risk for developing skin cancer due to their increased sun exposure. The primary objective of this review was to synthesize the current research literature that addresses sociodemographic and psychological factors related to sun protection behaviors in outdoor workers. Two additional purposes were to provide an overview of sun exposure and describe sun protection...

Actinic keratosis (AK) or lesions of epidermal dysplasia occurring in skin chronically exposed to solar radiation is very prevalent in lighter skin persons, with chronic long-term sun exposure being the major risk factor. With an aging population it is expected that the prevalence of AK will further increase. AK can progress to nonmelanoma skin cancer (NMSC) and is a public health concern. Six ...

The role of the mass media in communicating health-related information to the wider population is the focus of this paper. Using the example of sun protection within the UK, we highlight some of the major challenges to raising awareness of steadily increasing melanoma rates and of effective sun protection strategies. The implications of potential barriers to official sun protection messages via...

LINC complexes, consisting of inner nuclear membrane SUN proteins and outer nuclear membrane KASH proteins, connect the nucleus to the cytoskeleton, transmitting forces that control the nucleus's position within the cell. But how LINC complexes affect the cytoskeleton, and thus the balance of forces across cells and tissues, is less well understood. Stewart et al. now demonstrate that the LINC ...
