BACKGROUND: In 2006, the first human papillomavirus (HPV) vaccine was licensed in Europe and in 2007 it was included in the service catalogue of the statutory health insurance. The HPV vaccine led to a controversy in public and print media even before it was licensed. We evaluated the quality of the newspaper coverage of the HPV vaccine during the controversy in Germany. METHODS: The LexisNexis print media database was scanned for health journalism articles on HPV in 4 high-circulation national newspapers and 4 magazines using pre-defined search terms for the period 2006-2009...

Gliomas are the most common primary central nervous system (CNS) neoplasms in children and adolescents and are thought to arise from their glial progenitors or stem cells. Although the exact cells of origin for most pediatric gliomas remain to be identified, our current understanding is that specific cell populations during CNS development are susceptible to particular oncogenic events during certain time windows and thus give rise to pediatric gliomas with distinct histological, molecular, and clinical features...

Biologic treatments have revolutionized the way we treat inflammatory bowel disease patients (IBD). Anti-tumor necrosis factor (anti-TNF) antibodies are superior to conventional therapies to achieve sustained remission without steroids and mucosal healing. The objective of IBD treatment has evolved from symptom alleviation to a combination of absence of symptoms and intestinal healing. Nevertheless, biologics are expensive and are associated with an increased risk of infections and possibly skin cancers. Therefore, the duration of these treatments may be questioned, and stopping them may be contemplated by some patients and clinicians, while it is sometimes even imposed by some jurisdictions across the world...

The terrestrial Antarctic Realm has recently been divided into 16 Antarctic Conservation Biogeographic Regions (ACBRs) based on environmental properties and the distribution of biota. Despite their prominent role in the primary production and nutrient cycling in Antarctic lakes, cyanobacteria were only poorly represented in the biological dataset used to delineate these ACBRs. Here we provide a first high-throughput sequencing (HTS) insight into the spatial distribution of benthic cyanobacterial communities in Antarctic lakes located in four distinct, geographically distant ACBRs and covering a range of limnological conditions...

There is growing evidence that hepatitis E virus (HEV) infection can present with extrahepatic manifestations including neurological disorders. Among these, neuralgic amyotrophy (NA) has been reported to occur in some industrialized countries. We investigated 35 patients with NA and a control group for markers of HEV infection. Acute HEV infection was found in NA patients only and was associated with an inflammatory response in the central nervous system. Shedding of HEV RNA into the cerebrospinal fluid and intrathecal production of anti-HEV IgM occurred in one patient suggesting that HEV is neurotropic...

Summary: Genomic sequences are assembled into a variable, but large number of contigs that should be scaffolded (ordered and oriented) for facilitating comparative or functional analysis. Finding scaffolding is computationally challenging due to misassemblies, inconsistent coverage across the genome, and long repeats. An accurate assessment of scaffolding tools should take into account multiple locations of the same contig on the reference scaffolding rather than matching a repeat to a single best location...

Androgens are one class of steroids that could cause endocrine disrupting effects in aquatic organisms. However, little information is available about androgens in wastewater treatment plants (WWTPs) with different treatment technologies. Here we investigated the occurrence, removal, and fate of fourteen natural and synthetic androgens in ten WWTPs of Guangdong province, south China. The results showed detection of ten androgens in the influents of the ten WWTPs, with concentrations up to 4650 ng/L (androsta-1,4-diene-3,17-dione)...

Reverse osmosis concentrate (ROC) of printing and dyeing wastewater remains as a daunting environmental issue, which is characterized by high salinity, chemical oxygen demand (COD), chroma and low biodegradability. In this study electro-oxidation process (PbO2 /Ti electrode) coupled with oxidation-reduction potential (ORP) online monitor was applied to treat such a ROC effluent. The results show that with the increase of specific electrical charge (Qsp ), the removal efficiencies of COD, TN and chroma increased significantly at the incipience and then reached a gentle stage; the optimal total current efficiency (12...

Increasing access to early care and education (ECE) for children in the child welfare system (CWS) remains a critical issue in the United States, as the numbers of young children entering this system steadily increases. Mounting evidence suggests that participation in at least some types of ECE can mitigate the need for child welfare supervision. Moreover, ECE participation has been linked to positive developmental and school readiness outcomes, lower rates of foster placement, and greater placement stability for children in the CWS...

We have synthesized a wide array of structurally related amphiphilic compounds, containing a functionalized pyrrolidine polar group coupled to different ether-linked hydrocarbon chains, to generate novel structures with antitumor activity. These newly synthesized amphiphilic pyrrolidine-derived compounds were classified in three different sub-libraries regarding the number of hydroxyl groups substituting the pyrrolidine moiety at C3 and C4. Pyrrolidine compounds with one or none hydroxyl groups showed a potent cell killing activity against pancreatic cancer cells, but they lacked selectivity for tumor cells...

Ruthenium (Ru) complexes are known for their promising anticancer activity presumably due to octahedral coordination geometry, slow ligand exchange rate, the range of different oxidation states and target specificity. This review article summarizes the physicochemical processes which are responsible for the selectivity of Ru complexes toward cancer cells over the normal cells. Emphasis has been given on the activation mechanism of Ru(III) complex administered as a prodrug and then the release of active species in an acidic environment of cancer cell through normal or photo induced hydrolysis or ligand oxidation...

In this research, a sono-assisted chemical precipitation method was developed for a quick and efficient water-based synthesis of zinc sulfide (ZnS) quantum dots (QDs), in room temperature. ZnS QDs as pure and doped with some transition metal ions (such as Cu2+ , Mn2+ , Ag+ ) were prepared in the presence of l-cysteine, as capping agent. In comparison with the previous conventional methods, applying the ultrasonic irradiation provides a significant decrease in the reaction time. In comparison with previous reported conventional chemical QD synthesis methods, the required time for a complete synthesis in the presence of ultrasonic irradiations was significantly reduced to a period as short as 15 min, in a temperature of 40 °C...

Mass spectrometry (MS) is considered today as one of the most popular detection methods, due to its high selectivity and sensitivity. In particular, this detector has become the gold standard for the analysis of complex mixtures such as biological samples. The first successful SFC-MS hyphenation was reported in the 80's, and since then, several ionization sources, mass analyzers and interfacing technologies have been combined. Due to the specific physicochemical properties and compressibility of the SFC mobile phase, directing the column effluent into the ionization source is more challenging than in LC...

Substance-related and behavioral addictions are extremely prevalent and represent a major public health concern. In the ongoing attempt to understand the addictive personality, contradictory results have arisen from studies that have explored personality traits in different addiction populations. The diversity across addiction types suggests that some of these inconsistencies stem from distinct personalities underlying each addiction. The present study compares the personality profiles of several addictions, representing both substance (drugs and alcohol) and behavioral (gambling and sex) subtypes...

A shooting event involved several types of ammunition that were all shot from a single firearm. GSR analysis of samples taken from the suspect's hands, hair and from his clothes was carried out. Mixed compositions particles were found among other GSR particles, attributed to the weapon memory effect. SEM/EDX analysis of these particles highlighted a particle with defined domains containing distinct groups of elements. Some of these elements were absent in the primers mixtures of the ammunition used in the shooting event...
