BACKGROUND: A sufficient amount of bone is essential to ensure long-term stability of dental implants. To support the bone regeneration process, different techniques and materials are available. It has been questioned whether these techniques and materials may compromise implant survival compared to pristine bone. To properly answer this question, long-term stability up to 20.2 years after insertion of implants placed in augmented or non-augmented sites was retrospectively analysed. METHODS: Retrospective analysis included 10,158 implants from 3095 patients in three private practices who underwent implant therapy with or without bone augmentation procedures...

Real-time imaging was used to study the effects of a novel Fusarium-specific cyanoacrylate fungicide (JS399-19) on growth and morphology of four Fusarium sp. This fungicide targets the motor domain of type I myosin. Fusarium graminearum PH-1, Fusarium solani f. sp. pisi 77-13-4, Fusarium avenaceum IBT8464, and Fusarium avenaceum 05001, which has a K216Q amino-acid substitution at the resistance-implicated site in its myosin type I motor domain, were analyzed. Real-time imaging shows that JS399-19 inhibits fungal growth but not to the extent previously reported...

Manganese (Mn) is an essential trace element required for optimal functioning of cellular biochemical pathways in the central nervous system. Elevated exposure to Mn through environmental and occupational exposure can cause neurotoxic effects resulting in manganism, a condition with clinical symptoms identical to idiopathic Parkinson's disease. Epigenetics is now recognized as a biological mechanism involved in the etiology of various diseases. Here, we investigated the role of DNA methylation alterations induced by chronic Mn (100 µM) exposure in human neuroblastoma (SH-SY5Y) cells in relevance to Parkinson's disease...

Intracellular transport is performed by molecular motors that pull cargos along cytoskeletal filaments. Many cellular cargos are observed to move bidirectionally, with fast transport in both directions. This behaviour can be understood as a stochastic tug-of-war between two teams of antagonistic motors. The first theoretical model for such a tug-of-war, the Müller-Klumpp-Lipowsky (MKL) model, was based on two simplifying assumptions: (i) both motor teams move with the same velocity in the direction of the stronger team, and (ii) this velocity matching and the associated force balance arise immediately after the rebinding of an unbound motor to the filament...

β-glucans from Basidiomycetes like Grifola frondosa (the maitake mushroom) are well known for their health benefits. Polysaccharide preparations from medicinal mushrooms such as G. frondosa have been successfully tested in a vast number of studies. Many mushroom extracts have been developed and today are merchandized for use medicinally and commercially. Studies could show that, in particular, chemical structural features such as the molecular size of β-glucans significantly influence their bioactivity. Thus it is highly important to explore the composition and structural properties of β-glucans extracted from medicinal mushrooms and their effects on human tumor cell viability...

Aging is associated with a rising incidence of cutaneous squamous cell carcinoma (cSCC), an aggressive skin cancer with the potential for local invasion and metastasis. Acquisition of a senescence-associated secretory phenotype (SASP) in dermal fibroblasts has been postulated to promote skin cancer progression in elderly individuals. The underlying molecular mechanisms are largely unexplored. We show that Chemerin, a previously unreported SASP factor released from senescent human dermal fibroblasts, promotes cSCC cell migration, a key feature driving tumor progression...

Genetically homogenous strains of Plasmopara halstedii differing in host specificity and fungicide tolerance were used to test the hypothesis that asexual genetic recombination occurs and may account for the high genotype diversity of this homothallic reproducing oomycete, which causes downy mildew in sunflower. Dual inoculation of sunflower seedlings with single zoospore strains of complementary infection characteristics caused sporulation under conditions where inoculation with each strain alone failed to infect...

Meanwhile, five years have passed since the approval of the anti-BAFF antibody belimumab as a first biological for SLE, but no further SLE drug candidate is even close to approval. There are still no clinical trial data available for the use of new oral anticoagulants in antiphospholipid syndrome. In spite of convincing evidence for the use of mycophenolate mofetil (MMF) in lupus nephritis, the German "Gemeinsame Bundesausschuss" (GBA) has not yet decided on its reimbursement. However, several of the ongoing clinical trials have potential to lead to important advances in SLE treatment in the future...

Carbon exhibits a large number of allotropes and its phase behaviour is still subject to significant uncertainty and intensive research. The hexagonal form of diamond, also known as lonsdaleite, was discovered in the Canyon Diablo meteorite where its formation was attributed to the extreme conditions experienced during the impact. However, it has recently been claimed that lonsdaleite does not exist as a well-defined material but is instead defective cubic diamond formed under high pressure and high temperature conditions...

A total of 124 Taylorella (T.) equigenitalis and five T. asinigenitalis field isolates collected between 2002 and 2014 were available for genotyping using REP- (repetitive extragenic palindromic) PCR and PFGE (pulsed-field gel electrophoresis). The study comprised 79 T. equigenitalis field isolates originating from ten defined breeds of German horses and revealed a spectrum of five REP (rep-E1-E4, rep-E3a) and 15 PFGE (TE-A1-A9, TE-B1-B3, TE-C, TE-E1, and TE-E2) genotypes. T. equigenitalis field isolates (n=40) obtained from Austrian Lipizzaner horses were differentiated into three REP (rep-E1, rep-E3a, and rep-E4) and three PFGE genotypes (TE-A2, TE-A5, and TE-D); those isolated from four Austrian Trotters belonged to the REP/PFGE genotype rep-E2/TE-A1...

Recently, calcium was suggested to be the active moiety of acamprosate. We examined plasma calcium concentrations in association with severity of alcohol dependence and its interaction with regulating pathways and alcohol craving in alcohol-dependent patients. 47 inpatient alcohol-dependent patients undergoing detoxification treatment underwent laboratory testing, including calcium, sodium, liver enzymes as well as serum concentrations of calcitonin, parathyroid hormone and vitamin D. The psychometric dimension of craving was analyzed with the Obsessive Compulsive Drinking Scale (OCDS)...

Infections with sexually transmitted high-risk Human Papillomavirus (hrHPV), of which there are at least 15 genotypes, are responsible for a tremendous disease burden by causing cervical, and subsets of other ano-genital and oro-pharyngeal carcinomas, together representing 5% of all cancer cases worldwide. HPV subunit vaccines consisting of virus-like particles (VLP) self-assembled from major capsid protein L1 plus adjuvant have been licensed. Prophylactic vaccinations with the 2-valent (HPV16/18), 4-valent (HPV6/11/16/18), or 9-valent (HPV6/11/16/18/31/33/45/52/58) vaccine induce high-titer neutralizing antibodies restricted to the vaccine types that cause up to 90% of cervical carcinomas, a subset of other ano-genital and oro-pharyngeal cancers and 90% of benign ano-genital warts (condylomata)...

Pronograde trunk orientation in small birds causes prominent intra-limb asymmetries in the leg function. As yet, it is not clear whether these asymmetries induced by the trunk reflect general constraints on the leg function regardless of the specific leg architecture or size of the species. To address this, we instruct twelve participants to walk at a self-selected velocity with four postures: regular erect, with 30°, 50° and maximal trunk flexion. In addition, we simulate the axial leg force (along the line connecting hip and centre of pressure) using two simple models: spring and damper in series, and parallel spring and damper...

BACKGROUND: Lower urinary tract symptoms are highly prevalent and a large proportion of these symptoms are known to be associated with a dysfunction of the afferent pathways. Diagnostic tools for an objective and reproducible assessment of afferent nerve function of the lower urinary tract are missing. Previous studies showed first feasibility results of sensory evoked potential recordings following electrical stimulation of the lower urinary tract in healthy subjects and patients. Nevertheless, a refinement of the methodology is necessary...

: Gammaretroviruses, such as murine leukemia viruses (MLVs), encode, in addition to the canonical Gag, Pol, and Env proteins that will form progeny virus particles, a protein called "glycogag" (glycosylated Gag). MLV glycogag contains the entire Gag sequence plus an 88-residue N-terminal extension. It has recently been reported that glycogag, like the Nef protein of HIV-1, counteracts the antiviral effects of the cellular protein Serinc5. We have found, in agreement with prior work, that glycogag strongly enhances the infectivity of MLVs with some Env proteins but not those with others...

A 74-year-old man presented with a congenital naevus of the scalp that has lost its pigmentation over lifetime. Lately, he noticed a newly darkening patch within the grey hair area covering the naevus. The clinical examination revealed a palm-sized area of heavily pigmented hair on a 15x20 cm irregularly pigmented, poorly demarcated brown patch. This article is protected by copyright.
