STUDY QUESTION: Does fetuin-B inhibit premature zona pellucida (ZP) hardening in mouse oocytes in vitro and thus increase IVF rate? SUMMARY ANSWER: Supplementation of oocyte in vitro maturation (IVM) media with recombinant mouse fetuin-B (rmFetuB) increased fertilization rate without affecting mouse embryo development into blastocysts. WHAT IS KNOWN ALREADY: Mice deficient in fetuin-B are infertile owing to premature ZP hardening. Premature ZP hardening also occurs during oocyte IVM leading to decreased fertilization rate...

STUDY QUESTION: Does antisense oligonucleotide (ASO)-mediated down-regulation of serum fetuin-B cause an infertility-like fetuin-B gene deficiency in female mice? SUMMARY ANSWER: Pharmacological fetuin-B down-regulation by ASO therapy results in reversible infertility in female mice. WHAT IS KNOWN ALREADY: Female fetuin-B deficient (Fetub(-/-)) mice are infertile owing to premature zona pellucida (ZP) hardening. Enzyme activity studies demonstrated that fetuin-B is a potent and highly specific inhibitor of the zona proteinase ovastacin, which cleaves ZP protein 2 (ZP2) and thus mediates definitive ZP hardening...

BACKGROUND: Despite an obvious stabilization the prevalence of childhood overweight and obesity is still too high. Since childhood obesity may track into adulthood and lead to major health consequences, effective primary prevention programs are of high relevance. OBJECTIVE: In recent years several universal primary prevention programs, measures or projects have been developed and evaluated in Germany. This paper gives an overview. METHODS: An internet search and a search in the archive of the Deutsche Ärzteblatt were conducted to identify universal programs in Germany from 2006 to 2015...

Immune system deregulation and evasion play a key role in cancers' evolution and progression, including squamous cell carcinoma of the head and neck (SCCHN). Development of basic research proposed a whole new vision of cancer treatment, based on a strong biological rational, and targeting intrinsic deregulations. Immunotherapies provide an encouraging strategy for patients' improved outcomes. Immune-based therapies could act on cancer growth and/or development throughout many pathways. If cetuximab is for now the only monoclonal antibody approved for SCCHN management, other strategies, e...

Thanks to recent advances achieved in oncologic systemic and local ablative treatment, the treatments become more and more efficient in term of local control and overall survival. Thus, the targeted therapies, immunotherapy or stereotactic radiotherapy have modified the management of patients, especially in case of oligometastatic disease. Many questions are raised by these innovations, particularly the diagnosis and management of new side effects or that of the combination of these different treatments, depending on the type of primary tumor...

Staphylococcus aureus is a major clinically important pathogen with well-studied phage contributions to its virulence potential. In this commentary, we describe our method to enrich and sequence stealth extra-chromosomal DNA elements in the bacterial cell, allowing the identification of novel extra-chromosomal prophages in S. aureus clinical strains. Extra-chromosomal sequencing is a useful and broadly applicable tool to study bacterial genomics, giving a temporal glance at the extra-chromosomal compartment of the cell and allowing researchers to uncover lower-copy plasmidial elements (e...

Neutrophils are essential for innate immunity and inflammation and many neutrophil functions are β2 integrin-dependent. Integrins can extend (E(+)) and acquire a high-affinity conformation with an 'open' headpiece (H(+)). The canonical switchblade model of integrin activation proposes that the E(+) conformation precedes H(+), and the two are believed to be structurally linked. Here we show, using high-resolution quantitative dynamic footprinting (qDF) microscopy combined with a homogenous conformation-reporter binding assay in a microfluidic device, that a substantial fraction of β2 integrins on human neutrophils acquire an unexpected E(-)H(+) conformation...

BACKGROUND: We designed the EURAMOS-1 trial to investigate whether intensified postoperative chemotherapy for patients whose tumour showed a poor response to preoperative chemotherapy (≥10% viable tumour) improved event-free survival in patients with high-grade osteosarcoma. METHODS: EURAMOS-1 was an open-label, international, phase 3 randomised, controlled trial. Consenting patients with newly diagnosed, resectable, high-grade osteosarcoma aged 40 years or younger were eligible for randomisation...

Con A hepatitis is regarded as a T cell-mediated model of acute liver injury. Mincle is a C-type lectin receptor that is critical in the immune response to mycobacteria and fungi but does not have a well-defined role in preclinical models of non-pathogen-mediated inflammation. Because Mincle can ligate the cell death ligand SAP130, we postulated that Mincle signaling drives intrahepatic inflammation and liver injury in Con A hepatitis. Acute liver injury was assessed in the murine Con A hepatitis model using C57BL/6, Mincle(-/-), and Dectin-1(-/-) mice...

Lyme borreliosis (LB) is a multisystem disease caused by spirochetes in the Borrelia burgdorferi sensu lato (Bbsl) genospecies complex. We previously described a novel Borrelia species (type strain MN14-1420T) that causes LB among patients with exposures to ticks in the upper midwestern United States. Patients infected with the novel species demonstrated high levels of spirochetemia and differing clinical symptoms as compared to other Bbsl genospecies. The organism was detected from human specimens using polymerase chain reaction, microscopy, serology and culture...

BACKGROUND: It has been frequently argued that tissues evolved to suppress the accumulation of growth enhancing cancer inducing mutations. A prominent example is the hierarchical structure of tissues with high cell turnover, where a small number of tissue specific stem cells produces a large number of specialized progeny during multiple differentiation steps. Another well known mechanism is the spatial organization of stem cell populations and it is thought that this organization suppresses fitness enhancing mutations...

BACKGROUND: Evidence based virtual environments (VEs) that incorporate compensatory strategies such as cueing may change motor behavior and increase exercise intensity while also being engaging and motivating. The purpose of this study was to determine if persons with Parkinson's disease and aged matched healthy adults responded to auditory and visual cueing embedded in a bicycling VE as a method to increase exercise intensity. METHODS: We tested two groups of participants, persons with Parkinson's disease (PD) (n = 15) and age-matched healthy adults (n = 13) as they cycled on a stationary bicycle while interacting with a VE...

BACKGROUND: A unique archive of Big Data on Parkinson's Disease is collected, managed and disseminated by the Parkinson's Progression Markers Initiative (PPMI). The integration of such complex and heterogeneous Big Data from multiple sources offers unparalleled opportunities to study the early stages of prevalent neurodegenerative processes, track their progression and quickly identify the efficacies of alternative treatments. Many previous human and animal studies have examined the relationship of Parkinson's disease (PD) risk to trauma, genetics, environment, co-morbidities, or life style...

BACKGROUND: Information regarding the association of comorbidity indices with readmission risk for older adults receiving postacute care is limited. The purpose of this study was to compare the discriminatory ability of five comorbidity indices in predicting 30-day all-cause hospital readmission following discharge to the community from postacute inpatient rehabilitation facilities (IRF). METHODS: The sample included Medicare fee-for-service beneficiaries with stroke, lower extremity joint replacement, and fracture, discharged from IRF in 2011 (N = 75,582)...

Every data-rich community research effort requires a clear plan for ensuring the quality of the data interpretation and comparability of analyses. To address this need within the Human Proteome Project (HPP) of the Human Proteome Organization (HUPO), we have developed through broad consultation a set of mass spectrometry data interpretation guidelines that should be applied to all HPP data contributions. For submission of manuscripts reporting HPP protein identification results, the guidelines are presented as a one-page checklist containing fifteen essential points followed by two pages of expanded description of each...
