Odontoid fractures are the most common upper cervical spine fracture. There are two mechanisms in which odontoid fractures occur, most commonly hyperflexion of the neck resulting in displacement of the dens anteriorly and hyperextension resulting in posterior dens displacement. Type 2 fractures are the most common and are associated with ...

More than a decade ago, 'plasticity' suddenly became a 'fashionable' topic with overemphasized implications for regenerative medicine. The concept of 'plasticity' is supported by old transplantation work, at least for embryonic cells, and metaplasia is a classic example of plasticity observed in patients. Nevertheless, the publication of a series of ...

Subregional hypoxia is a common feature of tumors and is recognized as a limiting factor for the success of radiotherapy and chemotherapy. TH-302, a hypoxia-activated prodrug selectively targeting hypoxic regions of solid tumors, delivers a cytotoxic warhead to the tumor, while maintaining relatively low systemic toxicity. The antitumor activity, different ...

Understanding effects of species loss in complex food webs with multiple trophic levels is complicated by the idiosyncrasy of the predator effects on lower trophic levels: direct and indirect effects intermingle and may increase, decrease or not affect ecosystem functioning. We introduce a reductionist approach explaining a predator's trophic effect ...

Human papillomavirus (HPV) testing is more sensitive and has higher negative predictive value (NPV) than the Pap test for the detection of cervical intraepithelial neoplasia (CIN) in patients with atypical squamous cells of undetermined significance (ASCUS) cytology, but has low specificity, leading to high referral rates to second-level triage. Our ...

Relationships are of great importance during adolescence. Because of their social, communication and behavioral impairments, adolescents with Asperger's syndrome (AS) or high functioning autism (HFA) probably suffer from considerable impairment of their quality of life when facing their peers in school. Nevertheless, only one recent study has been published on ...

There is some discrepancy in the literature regarding whether acute stress is immunostimulatory or immunosuppressive. Studies of domesticated (laboratory and food) animals and humans typically indicate that acute stress is immunostimulatory, whereas studies of non-domesticated species document both immunostimulatory and immunosuppressive results. Few studies have examined the mechanisms responsible for ...

Previously considered a human commensal, Staphylococcus epidermidis is a frequent cause of nosocomial infections and the most common cause of device-related infections. Because the expression of toxins and other obvious virulence factors is less in S. epidermidis, the biofilm-forming capacity is its major virulence factor. Biofilm growth is characterized by ...

Virus-like particles (VLPs) are shell-like viruses that lack virus-specific genetic materials. Many viral-structured proteins can assemble into VLPs, which mimic the overall structure of virus particles and can elicit strong immune responses in a host. Dengue viruses (DENVs), from the genus Flavivirus, are transmitted to humans through the bites of ...

FSH is a key hormonal regulator of Sertoli cell secretory activity, required to optimize sperm production. To fulfil its biological function, FSH binds a G protein-coupled receptor, the FSH-R. The FSH-R-transduced signaling network ultimately leads to the transcription or down-regulation of numerous genes. In addition, recent evidence has suggested that ...
