Our experiments demonstrate that the use of the DC field achieves higher log removal efficiencies than the use of AC field.Computed tomography (CT) scanning is being increasingly employed in the study of natural history, particularly to investigate the internal anatomy of unique specimens in museum collections. Different techniques to enhance the contrast between tissues have been developed to improve the quality of the scans while preserving the integrity of these rare specimens. Diffusible iodine-based contrast enhanced computed tomography (diceCT) was found to be particularly effective and reversible for staining tissues in formalin preserved specimens. While it can also be effectively employed to stain ethanol-preserved specimens of small size, the reversibility of this process and the applicability to large-bodied animals has never been thoroughly tested. Here, we describe a novel diceCT protocol developed to stain and de-stain ethanol-preserved prenatal specimens of baleen whales (Mysticeti, Cetacea). These large (10-90 cm in length only considering early fetal stages) specimens present unique challenges as they are rare infeatures without recurring to dissection or other irreversible procedures. We also provide tips to best apply this protocol, from how to mix the solutions to how to minimize the staining time.
The purpose of this study was to assess whether the Strategic Partnership for Interprofessional Collaborative Education in the Pediatric Dentistry (SPICE-PD) program at the UCLA School of Dentistry positively affected interprofessional experiences and practice patterns of pediatric and general dentistry residents, pediatric medical residents, and pediatric nurse practitioner students (PNPs).
Data collection included a year-end online survey given to participants in the interprofessional program upon graduation from their UCLA dental/medical/nursing programs. Of the 318 participants who were recruited into SPICE-PD, 208 (65%; 208/318) completed the survey. Chi-square tests were used to assess differences in key outcome variables by dental/medical specialty.
Most dental, medical, and nursing participants thought SPICE-PD helped them learn to work more effectively with interprofessional colleagues and reported knowing more about the abilities and contributions of other health professionals as a result of the program. While most pediatric medical residents and PNPs thought SPICE-PD improved their skills to screen for early childhood caries (N=91% and N=100%), PNPs were more likely than pediatric medical residents to report SPICE-PD improved their skills to apply fluoride varnish (98%versus 72%; p<0.001). Almost all pediatric medical residents and PNPs thought primary care providers should incorporate oral health into routine patient care and provide referrals to dental professionals when necessary.
Increased interprofessional education and coordination of care through programs such as SPICE-PD can help bridge the gap between dental and medical care and lead to improved oral health outcomes and more comprehensive and preventive patient care.

The Interpersonal Psychological Theory of Suicide proposes two constructs that serve as a final common pathway to suicidal ideation thwarted belongingness and perceived burdensomeness. There have been few translations of this theory to clinical care. This study aimed to address this limitation by targeting burden cognitions with novel interventions.
A pilot clinical trial was conducted in an evidence-based intensive outpatient program for suicidal youth. Participants were 123 adolescents who completed measures at intake, discharge, and one-month follow-up. The experimental group consisted of standard care plus study interventions, which was compared with an active control group of standard care. Feedback on intervention acceptability was gathered through qualitative interviews with parents and adolescents.
There was a statistically significant drop in thwarted belongingness at discharge and an improvement in perceived burdensomeness at discharge (not statistically significant, small effect size). Feedback on acceptability was favorable and supported implementation.
This study adds to the literature by being the first to utilize the construct of perceived burdensomeness in clinical interventions for suicidal youth; illustrating one potential avenue for translating theory to practice. The unexpected effects on thwarted belongingness have implications for the role of these constructs in a treatment setting.

In ecotonal coastal wetland ecosystems, woody mangroves are encroaching into herbaceous salt marshes owing to changes in temperature, precipitation, and sediment dynamics. Increasing mangrove biomass in wetlands often increases carbon storage, which is high in these productive ecosystems, but little is known about how mangrove growth will change in response to warming. selleck chemicals To address this knowledge gap, we deployed warming experiments at three coastal wetland sites along a latitudinal gradient in northeast Florida where Avicennia germinans, black mangroves, are encroaching into salt marshes. We achieved air temperature warming (+1.6°C during the day) at all three sites and measured stem elongation, canopy height and area changes, and leaf and node number. After 2 yr of warming, we found that mangrove growth rate in height increased due to warming. Warming increased stem elongation by 130% over unwarmed control plots after 1 yr at the northern site.
