This cross-sectional study was conducted in Antananarivo, Madagascar, from June to September 2012. We aim to evaluate the misuse of TC on the face for cosmetic purpose and the adverse effects due to its application. A questionnaire-based analysis was done among females who use topical corticosteroids on the face for cosmetic purpose. Of the 770 women questioned, 384 (49,8%) used topical corticosteroids for cosmetic purpose whose mean age was 38 years (range 16-73 years). Two hundred and sixty-one females (68%) used TC combined with handcrafted cosmetics, and 123 (32%) used TC alone...

A novel methodology for the initiation of free radical and free radical promoted cationic photopolymerizations by insource lightening in the near infrared (NIR) region using upconverting glass (UCG) is reported. This approach pertains to the laser irradiation of UCG at 975 nm in the presence of Fluorescein (FL) and pentamethyldiethylene triamine (PMDETA). FL excited by blue light emitted from the UCG undergoes electron transfer reactions with PMDETA to form free radicals capable of initiating polymerization of methyl methacrylate...

Railway track irregularity surveying is important for the construction and the maintenance of railway lines. With the development of inertial devices, systems based on Inertial Navigation System (INS) have become feasible and popular approaches in track surveying applications. In order to overcome the requirement of high precision control points, this paper proposes a railway track irregularity measurement approach using the INS combined with the Zero Velocity Updates (ZUPT) technique and sub-decimeter scale landmarks...

We report the case of a patient with long-term history of hypertension, presenting with transient neurological disorders and severe graft failure several years after kidney transplantation. Cause of end-stage renal disease was hypertensive nephrosclerosis. Chronic hemodialysis lasted for 1 year. After transplantation and throughout follow-up, serum creatinine ranged from 200 to 230 μmol/L and maintenance immunosuppression included sirolimus and low-dose steroids. Six years after transplantation, the patient presented with right hip pain radiating to the lower back, transient aphasia, confusion, and hemiparesis...

Li anodes have been rapidly developed in recent years owing to the rising demand for higher-energy-density batteries. However, the safety issues induced by dendrites hinder the practical applications of Li anodes. Here, Li metal anodes stabilized by regulating lithium plating/stripping in vertically aligned microchannels are reported. The current density distribution and morphology evolution of the Li deposits on porous Cu current collectors are systematically analyzed. Based on simulations in COMSOL Multiphysics, the tip effect leads to preferential deposition on the microchannel walls, thus taking full advantage of the lightening rod theory of classical electromagnetism for restraining growth of Li dendrites...

Innovations in health, such as the use of tablet computers, show promise in broadening the scope of work of community health workers (CHWs), and play an important role in keeping CHWs and their clients up to date with advancements in health. While the use of mobile phones and tablets is innovative, the applicability of these technologies in different contexts remains poorly understood. Furthermore, little is known about the acceptability and feasibility of the use of video teaching tools on such devices across diverse contexts...

In European folk medicine, the fruits of Juniperus communis are used in the treatment of skin-related disorders such as skin infection, itching, and psoriasis. Previously, we reported that the EtOAc fraction of J. communis (EAJC) contained tyrosinase inhibition properties in vitro non-cellular experiment. The aim of this study was to evaluate anti-melanogenic effect of standardized EAJC on a hyperpigmentation animal model. Therapeutic effects of EAJC toward skin hyperpigmentation were confirmed by both in vivo experiment and in vitro cell-based assay...

Hyperpigmentation of skin is caused by several factors. UV exposure, in addition to oxidative stress elevates inflammatory mediators stimulating melanogenesis. Herbal derived compounds for improving skin lightness are gaining interest as they are perceived to be milder, safer and healthier than fully synthetic products. This review briefly addresses the causes of skin hyperpigmentation and extensively summarizes the status of herbs currently used in skin lightening cosmetics. The properties of active compounds and their dose rate information is summarized where available, along with human or anamial relevant models for activity testing...

Whereas geometric illusions in human faces have been reported by several studies, illusions of color or lightness in faces have seldom been explored. Here, we psychophysically investigated whether lip color influences facial skin's perceived lightness. Results of Experiment 1 demonstrated that redder lips lightened and darker lips darkened the perceived complexion. These lightness or darkness inducing effects differ from the classical illusion of lightness contrast in nonface objects for two reasons. First, illusory effects are more assimilative than contrastive...

BACKGROUND: Melasma (facial dermatoses) is an acquired chronic disorder of hyperpigmentation over sun exposed parts and continues to be a therapeutic challenge due to the presence of melanin at varying depths in the epidermis and dermis, and many researchers are working hard to find a solution. The main culprit to remain is direct sun exposure, with other factors like drugs, genetic predisposition, thyroid abnormalities, pregnancy, phototoxic and photoallergic cosmetics. Melasma continues to have a remarkable impact on the well-being of affected patients causing deep psychological and social anguish, and with the expansion of cosmetic dermatology globally, treatments that are successful against skin diseases and boost beauty without prolonged recovery periods, or exposing patients to the risks of surgery, are increasingly recognised and acknowledged...

Six medicinal halophytes widely represented in North Africa and commonly used in traditional medicine were screened for pharmacological properties to set out new promising sources of natural ingredients for cosmetic or nutraceutical applications. Thus, Citrullus colocynthis, Cleome arabica, Daemia cordata, Haloxylon articulatum, Pituranthos scoparius and Scorzonera undulata were examined for their in vitro antioxidant (DPPH scavenging and superoxide anion-scavenging, β-carotene bleaching inhibition and iron-reducing tests), antibacterial (microdilution method, against four human pathogenic bacteria) and anti-tyrosinase activities...

Despite the critical role of melanin in the protection of skin against UV radiation, excess production of melanin can lead to hyperpigmentation and skin cancer. Pear fruits are often used in traditional medicine for the treatment of melasma; therefore, we investigated the effects of pear extract (PE) and its component, protocatechuic acid (PCA), on melanogenesis in mouse melanoma cells. We found that PE and PCA significantly suppressed melanin content and cellular tyrosinase activity through a decrease in the expression of melanogenic enzymes and microphthalmia-associated transcription factor (Mitf) in α-melanocyte stimulating hormone-stimulated mouse melanoma cells...

The obstetrics-gynecology community has issued a call to action to prevent toxic environmental chemical exposures and their threats to healthy human reproduction. Recent committee opinions recognize that vulnerable and underserved women may be impacted disproportionately by environmental chemical exposures and recommend that reproductive health professionals champion policies that secure environmental justice. Beauty product use is an understudied source of environmental chemical exposures. Beauty products can include reproductive and developmental toxicants such as phthalates and heavy metals; however, disclosure requirements are limited and inconsistent...

Maternal grandmothers invest more in childcare than paternal grandmothers. This bias is large where the expression of preferences is unconstrained by residential and lineage norms, and is detectable even where marriage removes women from their natal families. We maintain that the standard evolutionary explanation, paternity uncertainty, is incomplete, and present an expanded model incorporating effects of alloparents on the mother as well as on her children. Alloparenting lightens a mother's load and increases her residual nepotistic value: her expected fitness from later investments in personal reproduction and in her natal relatives...

Ethosome formulations containing phenylethyl resorcinol (PR) were developed. The formulation was produced from 0.5% w/v PR, 0.5% w/v cholesterol from lanolin, 3% w/v L-α-phosphatidylcholine from soybean, 30% v/v absolute ethanol, and water up to 100% v/v. It was characterized by a vesicular size of 389 nm, low polydispersity index of 0.266, zeta potential of -34.19 ± 0.44 mV, high PR entrapment efficiency of 71%, and good stability on storage at 4 and 30°C at 75% RH for 4 months. In vitro studies using pig skin revealed that permeation coefficient of PR from ethosomes was significantly higher than that from liposomes...

Hydroquinone (HQ) is one of the most frequently used and effective skin-lightening products to treat skin hyperpigmentation disorders, including postinflammatory hyperpigmentation, melasma and solar lentigines. HQ is also widely used in cosmetic products for skin whitening. However, HQ treatment can evoke substantial skin irritation, a side effect that remains poorly understood. Here we demonstrate that HQ is an activator of the peripheral irritant receptor transient receptor potential (TRP) cation channel member A1 (TRPA1)...

CONTEXT: Lupus nephritis is the most common complication that causes the death of systemic lupus erythematosus patients. CD28/CTLA4 and their ligands CD80 or CD86 costimulatory pathway play a pivotal role in autoimmune disease and organ transplantation. OBJECTIVES: We generated a monoclonal antibody (clone 1D1) against human CD86 (1D1) that could recognize both human and mouse CD86, and blocked the CD86/CD28 costimulatory pathway with our mAb on a murine lupus nephritis model induced with chronic graft-versus-host disease (cGVHD)...
