Polycyclic aromatic hydrocarbons (PAHs) are toxic, mutagenic and carcinogenic organic compounds that are widely present in the environment. The bioremediation of PAHs is an economical and environmentally friendly remediation technique, but it is limited because PAHs have low water solubility and fewer bioavailable properties. The solubility and bioavailability of PAHs can be increased by using surfactants to reduce surface tension and interfacial tension; this method is called surfactant-enhanced remediation (SER)...

Chiari type 1 Malformation (CM 1) is a structural defect consisting of a displacement of the cerebellar tonsils through the foramen magnum causing obstruction of cerebrospinal fluid (CSF) outflow. CM 1 has a variety of presentation with headache being the most common symptom. The evaluation and treatment of headache related to CM 1 are often difficult, because the pain in the occipital-suboccipital region or headache that is of cough-type suggests symptomatic CM 1, but patients suffering from CM 1 can also report migraine or tension-type headache...

Recently we presented a computational model of articular cartilage calibrated for normal human tissue explants. This model was able to capture the transient deformation of cartilage experiencing a cyclic load. The model takes into account the tension-compression nonlinearity of the cartilage and incorporates the dependency of the compressive stiffness and fluid permeability of cartilage on the deformation-dependent aggrecan concentration in cartilage tissue. As such it represents a leading constitutive model of articular cartilage...

The purpose of this study is to compare the results of 2 techniques, tension band wiring (TBW) and fixation with screws, in olecranon fractures in children affected with osteogenesis imperfecta (OI) type I. Between 2010 and 2014, 21 olecranon fractures in 18 children with OI (average age: 12 years old) were treated surgically. Ten patients were treated with the screw fixation and 11 with TBW. A total of 65% of olecranon fractures occurred as a result of a spontaneous avulsion of the olecranon during the contraction of the triceps muscle...

The segregation of different cell types into distinct tissues is a fundamental process in metazoan development. Differences in cell adhesion and cortex tension are commonly thought to drive cell sorting by regulating tissue surface tension (TST). However, the role that differential TST plays in cell segregation within the developing embryo is as yet unclear. Here, we have analyzed the role of differential TST for germ layer progenitor cell segregation during zebrafish gastrulation. Contrary to previous observations that differential TST drives germ layer progenitor cell segregation in vitro, we show that germ layers display indistinguishable TST within the gastrulating embryo, arguing against differential TST driving germ layer progenitor cell segregation in vivo We further show that the osmolarity of the interstitial fluid (IF) is an important factor that influences germ layer TST in vivo, and that lower osmolarity of the IF compared with standard cell culture medium can explain why germ layers display differential TST in culture but not in vivo Finally, we show that directed migration of mesendoderm progenitors is required for germ layer progenitor cell segregation and germ layer formation...

Headaches, including primary headaches such as migraine and tension-type headache, are a common clinical problem. Complementary and integrative medicine (CIM), formerly known as complementary and alternative medicine (CAM), uses evidence informed modalities to assist in the health and healing of patients. CIM commonly includes the use of nutrition, movement practices, manual therapy, traditional Chinese medicine, and mind-body strategies. This review summarizes the literature on the use of CIM for primary headache and is based on five meta-analyses, seven systematic reviews, and 34 randomized controlled trials (RCTs)...

Prediction and analysis of the shapes of liquid-vapor interface of droplets under the influence of external forces is critical for various applications. In this regard, a geometric model which can capture the macroscopic shape of the liquid-vapor interface in tandem with the subtleties near the contact line, particularly in the regime where the droplet shape deviates significantly from the idealized spherical cap geometry, is desirable. Such deviations may occur when external forces such as gravity or centrifugal dominate over the surface tension force...

INTRODUCTION: Sleeve fractures of the patella are rare fractures that only occur in children. The diagnosis is difficult both clinically and radiologically since the distal bony fragment may be too small to be detectable by radiography. A high-riding patella and hemarthrosis are important signs of sleeve fractures. CASE REPORT: A 12-year-old boy was admitted to the emergency room after having felt a severe pain in his left knee on kicking the ground while skateboarding earlier that day...

Genetic and genomic studies, including genome-wide association studies (GWAS) have accelerated the discovery of genes contributing to glaucoma, the leading cause of irreversible blindness world-wide. Glaucoma can occur at all ages, with Mendelian inheritance typical for rare early onset disease (before age 40) and complex inheritance evident in common adult-onset forms of disease. Recent studies have suggested possible therapeutic targets for some patients with early-onset glaucoma based on the molecular and cellular events caused by MYOC, OPTN and TBK1 mutations...

Researchers have described the difficulties of doing abortion work, including the psychosocial costs to individual providers. Some have discussed the self-censorship in which providers engage in to protect themselves and the pro-choice movement. However, few have examined the costs of this self-censorship to public discourse and social movements in the US. Using qualitative data collected during abortion providers' discussions of their work, we explore the tensions between their narratives and pro-choice discourse, and examine the types of stories that are routinely silenced - narratives we name "dangertalk"...

Emulsion technology has been utilized extensively in the pharmaceutical industry. This article presents a comprehensive review of the literature on an important subcategory of emulsions, microemulsions. Microemulsions are optically transparent, thermodynamically stable colloidal systems, 10-100nm diameter, that form spontaneously upon mixing of oil, water and emulsifier. This review is the first to address advantages and disadvantages, as well as considerations and challenges in multi-drug delivery. For the period 1 January 2011-30 April 2016, 431 publications related to microemulsion drug delivery were identified and screened according to microemulsion, drug classification, and surfactant types...

The arrival of DNA paternity testing in the 1980s was met with great enthusiasm in the Brazilian courts. Yet, over the past two decades, Brazilian legal doctrine and jurisprudence have increasingly rejected DNA proof as the sine qua non for paternity cases. Instead, DNA paternity testing has generated mountains of litigation, as biological proof has been challenged by the argument that paternity is primarily "socio-affective". Leading family law specialists describe this new conception of paternity as an outcome of the "revolutionary" provisions of the 1988 Constitution, which recognizes the "pluralism" of family forms in modern society and guarantees equal family rights for all children...

Nematic liquid crystals (NLCs) of achiral molecules and racemic mixtures of chiral ones form flat films and show uniform textures between circular polarizers when suspended in sub-millimeter size grids and immersed in water. On addition of chiral dopants to the liquid crystal, the films exhibit optical textures with concentric ring patterns and radial variation of the birefringence color. Both are related to a biconvex shape of the chiral liquid crystal film; the rings are due to interference. The curvature radii of the biconvex lens array are in the range of a few millimeters...

BACKGROUND: The prevalence of primary headache disorders in the general population provides a unique challenge in the evaluation of headache occurring in the context of sport. Despite a wealth of studies exploring the epidemiology of headache in the layperson, little is known about the prevalence and nature of headaches in collegiate student-athletes. These scenarios are challenging in the return to play context, as it is often unclear whether an athlete has an exacerbation of a primary headache disorder, new onset headache unrelated to trauma, or has suffered a concussive injury...
