Individuals within monogamous species form bonds that may buffer against the negative effects of stress on physiology and behavior. In some species, involuntary termination of the mother-offspring bond results in increased symptoms of negative affect in the mother, suggesting that the parent-offspring bond may be equally as important as the pair bond. To our knowledge, the extent to which affect in paternal rodents is altered by involuntary termination of the father-offspring bond is currently unknown. Here, we investigated to what extent separation and paternal experience alters passive stress-coping behaviors and dendritic morphology in hippocampal subfields of California mice (Peromyscus californicus)...

Serpentinization is a widespread geochemical process associated with aqueous alteration of ultramafic rocks that produces abundant reductants (H2 and CH4) for life to exploit, but also potentially challenging conditions, including high pH, limited availability of terminal electron acceptors, and low concentrations of inorganic carbon. As a consequence, past studies of serpentinites have reported low cellular abundances and limited microbial diversity. Establishment of the Coast Range Ophiolite Microbial Observatory (California, U...

The production of hydrogen and methane by geochemical reactions associated with the serpentinization of ultramafic rocks can potentially support subsurface microbial ecosystems independent of the photosynthetic biosphere. Methanogenic and methanotrophic microorganisms are abundant in marine hydrothermal systems heavily influenced by serpentinization, but evidence for methane-cycling archaea and bacteria in continental serpentinite springs has been limited. This report provides metagenomic and experimental evidence for active methanogenesis and methanotrophy by microbial communities in serpentinite springs of the Voltri Massif, Italy...

PURPOSE: To develop a volumetric modulated arc therapy (VMAT) planning and delivery methodology for lung stereotactic body radiation therapy (SBRT) that addresses the unique geometric challenges presented when using an Elekta VersaHD linear accelerator. METHODS: The Elekta VersaHD imaging panels are fixed at 160cm SID when deployed, limiting the ability to perform non-coplanar treatments due to collisions with the treatment table. The panels can be folded in a stored position for non-coplanar treatments, but in this configuration, longitudinal table travel is restricted by the space required for the folded panels...

The naviculocuneiform articulation is composed of the navicular proximally and the 3 cuneiforms distally. It is not uncommon to perform surgical interventions at this joint for multiple pathologic foot etiologies. To date, no detailed anatomic measurement is available for each cuneiform articulation on the navicular. The purpose of the present study was to present an anatomic description of this complex joint to aid in better surgical understanding and improve surgical outcomes. Ten fresh, frozen, and thawed below-the-knee cadaveric specimens were used for anatomic dissection of the navicular and associated cuneiforms...

Mark A Prissel, Christopher F Hyer, Gregory C Berlet
Total ankle replacement (TAR) is an accepted treatment for end-stage ankle arthritis. When concurrent subtalar joint pathologic features exist, ipsilateral subtalar joint arthrodesis (STJA) can be performed either simultaneous with TAR or as a staged procedure. Limited data exist on the effect of talar component subsidence and prosthesis survivorship. The present study purpose was to evaluate the effect of STJA on talar component subsidence after primary TAR and its effect on TAR survivorship. All patients, a minimum of 18 years old, from a single institution with modern-generation TAR and 1-year minimum follow-up data available were evaluated...

BACKGROUND: Several studies have identified the association between ambient temperature and mortality; however, several features of temperature behavior and their impacts on health remain unresolved. We obtain daily counts of nonaccidental all-cause mortality data in the elderly (65 + years) and corresponding meteorological data for Melbourne, Australia during 1999 to 2006. We then characterize the temporal behavior of ambient temperature development by quantifying the rates of temperature change during periods designated by pre-specified windows ranging from 1 to 30 days...

Ankle fractures are a common injury treated by orthopaedic surgeons. The distal tibiofibular syndesmosis can be injured during these fractures as well as in isolation. They pose a significant challenge with regard to the diagnosis of instability as well as evaluating reduction after fixation. Multiple studies have demonstrated that traditional radiographic analysis fails to accurately identify syndesmotic diastasis, instability, or malreduction. Ankle arthroscopy has been proposed as an alternative way to evaluate the syndesmosis...

First metatarsophalangeal joint arthritis can stem from a biomechanical imbalance as in hallux abducto valgus, metabolic arthritidies such as rheumatoid or gout, and even in posttraumatic cases. Advanced arthritis in the foot and ankle can often become debilitating. Surgical intervention is often necessary. Revision of failed first metatarsophalangeal joint arthroplasty is often in the setting of bony erosion and lysis, cystic changes, and loss of bone stock. In this article, we describe first metatarsophalangeal distraction arthrodesis technique using tricortical calcaneus autograft with the aim of simplifying donor site graft harvesting and decreasing donor site morbidity while attaining successful osseous union...
