<p>Port-wine stain (PWS) is the second most common congenital vascular malformation characterized as ectatic capillaries and venules in the dermis that clinically appears as a deep red to purple patch on the skin. Typically, PWS progressively darken and may become hypertrophic or nodular without treatment. There are several treatment options available for PWS from topical antiangiogenic agents to laser therapies. Vascular-specific lasers are the gold standard in treating PWS and classically pulsed dye lasers are usually the treatment of choice...

<p>Purpose: Though hydroquinone (HQ) remains the gold standard for treatment of hyperpigmentation, concerns about its safety have prompted the development of HQ-free topical skin lightening systems. OBJECTIVE: To compare the efficacy and tolerability of a new HQ-free system and a popular HQ-based system for the improvement of facial hyperpigmentation and photoaging in darker skin types. METHODS: This investigator-blinded trial randomized 30 subjects of Fitzpatrick skin types III to VI with moderate to severe hyperpigmentation to a new 7-product HQ-free system or a 7-product HQ-based system for 12 weeks...

Compared to their rural non-farming peers, farmers are less likely to access preventive healthcare services; however, the reasons for this disparity are poorly understood. We conducted semi-structured interviews with a total of 30 farm household members in central New York. Interview topics included farming identity, perceptions of one's health, past experiences with acute and preventive healthcare, and attitudes toward seeking healthcare services. Grounded Theory analysis of the interview transcripts revealed that (1) utilizing healthcare services is felt to be in conflict with the farming identity, (2) the need to conserve time and money for farm applications poses a barrier to healthcare utilization, (3) farmers decide to seek healthcare when they believe it is necessary to ensure survival of the farm, and (4) the decision to seek healthcare is most strongly driven by the presence of intolerable symptoms, prompting from others, and the perception that treatment will yield clear benefits...

The 2017 Faraday Discussion on Complex Molecular Surfaces and Interfaces brought together theoreticians and experimentalists from both physical and chemical backgrounds to discuss the relevant applied and fundamental research topics within the broader field of chemical surface analysis and characterization. Main discussion topics from the meeting included the importance of "disordered" two-dimensional (2D) molecular structures and the utility of kinetically trapped states. An emerging need for new experimental tools to address dynamics and kinetic pathways involved in self-assembled systems, as well as the future prospects and current limitations of in silico studies were also discussed...

Laboratory colonies of phlebotomine sand flies are necessary for experimental study of their biology, behaviour and mutual relations with disease agents and for testing new methods of vector control. They are indispensable in genetic studies and controlled observations on the physiology and behaviour of sand flies, neglected subjects of high priority. Colonies are of particular value for screening insecticides. Colonized sand flies are used as live vector models in a diverse array of research projects, including xenodiagnosis, that are directed toward control of leishmaniasis and other sand fly-associated diseases...

Today, invasive and non-invasive home mechanical ventilation have become a well-established treatment option. Consequently, in 2010 the German Society of Pneumology and Mechanical Ventilation (DGP) has leadingly published the guidelines on "Non-Invasive and Invasive Mechanical Ventilation for Treatment of Chronic Respiratory Failure". However, continuing technical evolutions, new scientific insights, and health care developments require an extensive revision of the guidelines.For this reason, the updated guidelines are now published...

Akihiro Ohmoto, Shinichi Yachida
Inhibitors of poly(ADP-ribose) polymerases (PARPs), which play a key role in DNA damage/repair pathways, have been developed as antitumor agents based on the concept of synthetic lethality. Synthetic lethality is the idea that cell death would be efficiently induced by simultaneous loss of function of plural key molecules, for example, by exposing tumor cells with inactivating gene mutation of BRCA-mediated DNA repair to chemically induced inhibition of PARPs. Indeed, three PARP inhibitors, olaparib, rucaparib and niraparib have already been approved in the US or Europe, mainly for the treatment of BRCA-mutant ovarian cancer...

The purpose of this work was to prepare and characterize an innovative formulation for vaginal delivery of econazole nitrate, commonly used for the treatment of Candida infections. A novel biosurfactant isolated from a vaginal Lactobacillus strain was used to prepare phosphatidylcholine based mixed vesicles. Biosurfactant was produced by Lactobacillus gasseri BC9, isolated from the vagina of a healthy premenopausal woman, and was chemically characterized by FT-IR and ESI-MS. Mixed vesicles, obtained through film rehydration and extrusion method, were characterized in terms of size, zeta potential, encapsulation efficiency, mucoadhesion properties and econazole release...

BACKGROUND: With the development of chromosomal conformation capturing techniques, particularly, the Hi-C technique, the study of the spatial conformation of a genome is becoming an important topic in bioinformatics and computational biology. The Hi-C technique can generate genome-wide chromosomal interaction (contact) data, which can be used to investigate the higher-level organization of chromosomes, such as Topologically Associated Domains (TAD), i.e., locally packed chromosome regions bounded together by intra chromosomal contacts...

Naming game simulates the evolution of vocabulary in a population of agents. Through pairwise interactions in the games, agents acquire a set of vocabulary in their memory for object naming. The existing model confines to a one-to-one mapping between a name and an object. Focus is usually put onto name consensus in the population rather than knowledge learning in agents, and hence simple learning model is usually adopted. However, the cognition system of human being is much more complex and knowledge is usually presented in a complicated form...

Eosinophilic esophagitis (EoE) and celiac disease (CeD) are chronic immune mediated gastrointestinal disorders characterized by mucosal inflammation, both of which are related to food antigens, but with differences in clinical and histopathological features. When untreated, both diseases lead to destruction of the epithelium. While a strict gluten-free diet is the only effective therapy for CeD, several therapeutic options, such as proton pump inhibitors, topical steroids and diet elimination therapy are available for EoE...

Recently, a number of studies have demonstrated the existence of a link between the emotional and cognitive centres of the brain and peripheral functions through the bi-directional interaction between the central nervous system and the enteric nervous system. Therefore, the use of bacteria as therapeutics has attracted much interest. Recent research has found that there are a variety of mechanisms by which bacteria can signal to the brain and influence several processes in relation to neurotransmission, neurogenesis, and behaviour...

Speciation genetics research in diverse organisms shows the X-chromosome to be exceptional in how it contributes to 'rules' of speciation. Until recently, however, the nematode phylum has been nearly silent on this issue, despite the model organism Caenorhabditis elegans having touched most other topics in biology. Studies of speciation with Caenorhabditis accelerated with the recent discovery of species pairs showing partial inter-fertility. The resulting genetic analyses of reproductive isolation in nematodes demonstrate key roles for the X-chromosome in hybrid male sterility and inviability, opening up new understanding of the genetic causes of Haldane's rule, Darwin's corollary to Haldane's rule, and enabling tests of the large-X effect hypothesis...

Plant regeneration at the cellular and tissue level is a unique process. Similar to animals, the stem cells in plants have properties that help stimulate and regenerate plants after injury. The unique properties of plant stem cells have been a recent area of interest and focus both in developing new cosmetics and studying how these extracts/phytohormones will influence animal skin. This special report focuses on the current evidence-based trends in plant stem cell-based cosmetics and sheds light on the challenges that we need to overcome in order to see meaningful changes in human skin using topical cosmetics derived from plant stem cells...

Franck Courchamp, Corey J A Bradshaw
Reading scientific articles is a valuable and major part of the activity of scientists. Yet, with the upsurge of currently available articles and the increasing specialization of scientists, it becomes difficult to identify, let alone read, important papers covering topics not directly related to one's own specific field of research, or that are older than a few years. Our objective was to propose a list of seminal papers deemed to be of major importance in ecology, thus providing a general 'must-read' list for any new ecologist, regardless of particular topic or expertise...

PURPOSE/AIM: Glaucoma consists of a group of progressive optic neuropathies that are characterized by degeneration of the optic nerve and irreversible visual filed loss. Elevated intraocular pressure is the only proven treatable risk factor and commercial products used for glaucoma treatment are focused in lowering intraocular pressure. These drugs can have various undesirable side effects and this invites to look for new strategies. The purpose of this work is to study the use of a siRNA (small interfering RNA) to selectively silence beta2 adrenergic receptors and to see whether it reduces IOP (intraocular pressure)...
