Background The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging. Materials and Methods This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups...

Urban songbirds of several species more vigorously defend their territories in response to conspecific song playback than do their rural counterparts, but the hormonal basis of this behavioral difference is unclear. It is well established in vertebrates that both testosterone and corticosterone affect the intensity of territoriality. Previous studies have found no evidence that initial (i.e., immediately follow territorial challenge, but prior to restraint) plasma testosterone accounts for the elevated territorial aggression of urban birds...

Surface functionalization of nanoparticles (NPs) with stealth polymers (e.g., hydrophilic and zwitterionic polymers) has become a common strategy to resist non-specific protein adsorption recently. Understanding the role of surface decoration on NP-biomembrane interactions is of great significance to promote the application of NPs in biomedical fields. Herein, using coarse-grained molecular dynamics (CGMD) simulations, we investigate the interactions between stealth polymer-coated gold nanoparticles (AuNPs) and lipid membranes...

During July 2016-January 2017, two unrelated measles cases were identified in the Denver, Colorado area after patients traveled to countries with endemic measles transmission. Each case resulted in multiple exposures at health care facilities and public venues, and activated an immediate and complex response by local and state public health agencies, with activities led by the Tri-County Health Department (TCHD), which serves Adams, Arapahoe, and Douglas counties. To track the economic burden associated with investigating and responding to single measles cases, personnel hours and supply costs incurred during each investigation were tracked prospectively...

BACKGROUND: Staged subpectoral expander-implant breast reconstruction is widely performed. Disruption of the pectoralis major origin and the frequent occurrence of animation deformity and functional discomfort associated with subpectoral reconstruction remain ongoing concerns. Prepectoral single-stage direct-to-implant reconstruction resolves many of these issues. In this study, the authors explored the rationale for prepectoral single-stage implant-based breast reconstruction with anterior AlloDerm coverage as an alternative to the staged approach...

Prepectoral breast reconstruction has emerged as an excellent technique for postmastectomy reconstruction, as it allows for full preservation of a patient's pectoralis major muscle and chest wall function. This reduces pain, eliminates animation deformity, and results in high patient satisfaction. Safely performed prepectoral breast reconstruction requires a careful patient selection process before committing to the procedure, taking into account comorbidities, radiation status, and oncologic criteria such as tumor location and breast cancer stage...

We study effective two- and three-body interactions between non-active colloidal inclusions in an active bath of chiral or non-chiral particles, using Brownian dynamics simulations within a standard, two-dimensional model of disk-shaped inclusions and active particles. In a non-chiral active bath, we first corroborate previous findings on effective two-body repulsion mediated between the inclusions by elucidating the detailed non-monotonic features of the two-body force profiles, including a primary maximum and a secondary hump at larger separations that was not previously reported...

It is argued that the mesolimbic system has a more general function in processing all salient events, including and extending beyond rewards. Saliency was defined as an event that is unexpected due to its frequency of occurrence and elicits an attentional-behavioral switch. Using functional magnetic resonance imaging (fMRI), signals were measured in response to the modulation of salience of rewarding and nonrewarding events during a reward-based decision making task, the so called desire-reason dilemma paradigm (DRD)...

Aims: Investigators have proposed that cardiovascular magnetic resonance (CMR) should have restrictions similar to those of ionizing imaging techniques. We aimed to investigate the acute effect of 1.5 T CMR on leucocyte DNA integrity, cell counts, and function in vitro, and in a large cohort of patients in vivo. Methods and results: In vitro study: peripheral blood mononuclear cells (PBMCs) were isolated from healthy volunteers, and histone H2AX phosphorylation (γ-H2AX) expression, leucocyte counts, and functional parameters were quantified using flow cytometry under the following conditions: (i) immediately following PBMC isolation, (ii) after standing on the benchside as a temperature and time control, (iii) after a standard CMR scan...
