Background: The main goal of cervical screening programs is to detect and treat precancer before cancer develops. Human papillomavirus (HPV) testing is more sensitive than cytology for detecting precancer. However, reports of rare HPV-negative, cytology-positive cancers are motivating continued use of both tests (cotesting) despite increased testing costs. Methods: We quantified the detection of cervical precancer and cancer by cotesting compared with HPV testing alone at Kaiser Permanente Northern California (KPNC), where 1 208 710 women age 30 years and older have undergone triennial cervical cotesting since 2003...

Spatial synchrony and cycles are common features of forest insect pests, but are often studied as separate phenomenon. Using time series of timber damage caused by Dendroctonus frontalis Zimmermann (Coleoptera: Curculionidae) (southern pine beetle) in 10 states within the southern United States, this study examines synchrony in D. frontalis abundance, the synchronizing effects of temperature extremes, and the evidence for shared cycles among state populations. Cross-correlation and cluster analyses are used to quantify synchrony across a range of geographic distances and to identify groups of states with synchronous dynamics...

Ectopic heartbeats can trigger reentrant arrhythmias, leading to ventricular fibrillation and sudden cardiac death. Such events have been attributed to perturbed Ca2+ handling in cardiac myocytes leading to spontaneous Ca2+ release and delayed afterdepolarizations (DADs). However, the ways in which perturbation of specific molecular mechanisms alters the probability of ectopic beats is not understood. We present a multiscale model of cardiac tissue incorporating a biophysically detailed three-dimensional model of the ventricular myocyte...

RATIONALE: Cervical nerve root injury is one of the complications of traumatic cervical spine fracture. Although one of the most effective treatments to reduce inflammation in nerve root injuries is the use of corticosteroids or nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids and NSAIDs can inhibit bone healing. So, when nerve injury accompanies bone fractures, corticosteroids and NSAIDs have limitations as therapeutic agents. However, polydeoxyribonucleotide (PDRN) may be useful in the treatment of neuropathy or musculoskeletal pain patients with contraindication of the use of corticosteroids because of its anti-inflammatory effect, as revealed in previous studies...

Deep-sea hydrothermal vent is one of the most extreme environments on Earth with low oxygen and high levels of toxins. Decapod species from the family Alvinocarididae have colonized and successfully adapted to this extremely harsh environment. Mitochondria plays a vital role in oxygen usage and energy metabolism, thus it may be under selection in the adaptive evolution of the hydrothermal vent shrimps. In this study, the mitochondrial genome (mitogenome) of alvinocaridid shrimp Shinkaicaris leurokolos (Kikuchi & Hashimoto, 2000) was determined through Illumina sequencing...
