In Persian nutrition culture, drinking aromatic waters (hydrosols, distillate) has a long history as functional beverages or therapeutic remedies. The co-distilled water with essential oils, which contains partial amounts of more water-soluble volatile compounds are diluted and used as beverages. Since the solubility of volatile components is different in water, the overall composition, and thus the biological activities of aromatic waters seem to be different from the essential oils they were co-distilled with...

1.Deciding when to terminate care of offspring is a key consideration for parents. Prolonging care may increase fitness of current offspring, but it can also reduce opportunities for future reproduction. Despite its evolutionary importance, few studies have explored the optimal duration of parental care, particularly among large carnivores. 2.We used a 40-year dataset to assess the trade-offs associated with the length of maternal care in leopards in the Sabi Sand Game Reserve, South Africa. We compared the costs imposed by care on the survival and residual reproductive value of leopard mothers against the benefits derived from maternal care in terms of increased offspring survival, recruitment and reproduction...

BACKGROUND: A lasagna plot is a graphical tool that can display multiple longitudinal outcomes. To our knowledge, lasagna plots have not been used in publications of surgical studies before. The objective of this study was to demonstrate the results of surgical randomized controlled trials (RCTs) with lasagna plots in order to assess whether this can lead to new observations of the data presented in the original studies. MATERIAL AND METHODS: Lasagna plots were created with R for an RCT comparing endovascular and open repair for patients with a ruptured abdominal aortic aneurysm (AJAX trial), an RCT comparing laparoscopy or open surgery combined with either fast track or standard care for patients with colon cancer (LAFA trial) and an RCT comparing preoperative biliary drainage and early surgery for patients with pancreatic cancer (DROP trial)...

Increasing evidence indicates that angiogenesis inhibitors regulate obesity. This study aimed to determine whether the lemon balm extract ALS-L1023 inhibits diet-induced obesity and nonalcoholic fatty liver disease (NAFLD) in female ovariectomized (OVX) mice. OVX mice received a low fat diet (LFD), a high fat diet (HFD) or HFD supplemented with ALS-L1023 (ALS-L1023) for 15 weeks. HFD mice exhibited increases in visceral adipose tissue (VAT) angiogenesis, body weight, VAT mass and VAT inflammation compared with LFD mice...

Lysozyme from hen egg white is composed by a unique linear chain of 129 amino acids. It is known to inhibit Gram positive bacteria and to form amyloid fibrils at low pH, under 75°C. This work investigates the effect of the fibrillation and/or adsorption onto a layered double hydroxide material on the antibacterial properties of lysozyme. The kinetics of adsorption follows a behavior of pseudo second order model. The X-ray diffraction and the Fourier transform infrared spectroscopy highlight that adsorption occurs only on the external surface of the material...

Cosmetics are part of the daily life of most of the people. Thus, a complete characterization of the products we applied in our skin is necessary. In this work, an analytical investigation of a wide variety of cosmetics from the point of view of total element content and metallic nanoparticles (NPs) has been performed. Firstly, we analyzed the total element content by ICP-MS and ICP-OES after acid digestion as an assessment of the presence of metal impurities. Prohibited elements in cosmetics, according to the European Commission regulation No 1223/2009, were not detected, and only elements mentioned in the label were found (e...

BACKGROUND: Mucosal melanomas are rare and highly aggressive tumors. Few studies evaluated mucosal melanomas of locations other than the head and neck region, and other than those of the Asian population. OBJECTIVES: The objective of this study was to analyze the clinical and histological features, as well as the mutational status of c-kit and b-raf gene of mucosal melanoma in any localization in a French series. METHODS: We investigated clinical (sex, age, performance status, survival, treatment of the patients and lack of pigmentation of the tumors) and histopathologic features (ulceration, Breslow's index, mitotic rate), as well as the mutational status of c-kit and b-raf of 86 mucosal melanomas diagnosed in 15 years in four French University Hospitals...

The rapid rise of two-dimensional nanomaterials implies the development of new versatile, high-resolution visualization and placement techniques. For example, a single graphene layer becomes observable on Si/SiO2 substrates by reflected light under optical microscopy because of interference effects when the thickness of silicon oxide is optimized. However, differentiating monolayers from bilayers remains challenging, and advanced techniques, such as Raman mapping, atomic force microscopy (AFM), or scanning electron microscopy (SEM) are more suitable to observe graphene monolayers...

Wildland firefighters suppressing wildland fires or conducting prescribed fires work long shifts during which they are exposed to high levels of wood smoke with no respiratory protection. Polycyclic aromatic hydrocarbons (PAHs) are hazardous air pollutants formed during incomplete combustion. Exposure to PAHs was measured for 21 wildland firefighters suppressing two wildland fires and 4 wildland firefighters conducting prescribed burns in California. Personal air samples were actively collected using XAD4-coated quartz fiber filters and XAD2 sorbent tubes...

Thiamine deficiency and beriberi are prevalent in Cambodia, although most infants with nonspecific clinical symptoms of beriberi, including tachypnea, lack echocardiographic evidence diagnostic of the disease. Camphor activates transient receptor potential vanilloid 3 (TRPV3), a nonselective ion channel expressed in the medial preoptic nucleus of the hypothalamus and thought to be important for thermo-sensitivity. Because camphorated ointments are used commonly among Cambodian infants, we hypothesized that topical camphor modulates thermoregulatory behaviors, causing beriberi-simulating tachypnea, separate from any influence of thiamine deficiency...

BACKGROUND: Many people use lip care products daily to prevent dry lips. However, some people, especially those with sensitive skin-consciousness, complain of various skin problems on their lips including contact dermatitis caused by lip care products. Dry lips have decreased water holding capacity and cutaneous barrier function as well as reduced stratum corneum ceramide levels. In this study, we investigated the usefulness of a newly formulated lip balm containing pseudo-ceramide for the dry lips of subjects with sensitive skin...

Layered double hydroxide (LDH) nanohybrid intercalated biomolecules, including oligonecluotides, genes and peptides/proteins, have attracted particular attention since they exhibit improved safety and effectiveness as successful delivery biosystems. The current study specifically investigated the adsorption of nisin peptide and precisely the control of the release of the payload. Adsorption occurred from peptide solution in contact with zinc-aluminum LDH at room temperature, looking out over the influence of the Zn(2+)/Al(3+) ratio, the anion exchange capacity, the nature of the intercalated anion, the host matrix, and the host morphology...

In this work, we report the design and the fine-tuning of boron nitride single nanopore and nanoporous membranes by atomic layer deposition (ALD). First, we developed an ALD process based on the use of BBr3 and NH3 as precursors in order to synthesize BN thin films. The deposited films were characterized in terms of thickness, composition, and microstructure. Next, we used the newly developed process to grow BN films on anodic aluminum oxide nanoporous templates, demonstrating the conformality benefit of BN prepared by ALD, and its scalability for the manufacturing of membranes...

Health disparities related to race, ethnicity, and socioeconomic status persist and are commonly encountered by practitioners of pediatric and adult pulmonary, critical care, and sleep medicine in the United States. To address such disparities and thus progress toward equality in respiratory health, the American Thoracic Society and the National Heart, Lung, and Blood Institute convened a workshop in May of 2015. The workshop participants addressed health disparities by focusing on six topics, each of which concluded with a panel discussion that proposed recommendations for research on racial, ethnic, and socioeconomic disparities in pulmonary, critical care, and sleep medicine...

During a field campaign in the Sahara Desert in southern Morocco, spring 2012, we sampled the vertical grain size distribution of two active dust devils that exhibited different dimensions and intensities. With these in situ samples of grains in the vortices, it was possible to derive detailed vertical grain size distributions and measurements of the lifted relative particle load. Measurements of the two dust devils show that the majority of all lifted particles were only lifted within the first meter (∼46...
