Rape Prevention and Education 2021: Principles-Focused Evaluation Measurement Tools
Throughout 2020, sexual violence (SV) preventionists across Nebraska came together to identify prevention principles for Nebraska RPE. Preventionists identified and agreed upon the following eight prevention principles
Characterization of substrates and inhibitors of the human heterodimeric transporter 4F2hc-LAT1 using purified protein and the scintillation proximity radioligand binding assay.
Amino acids have diverse and essential roles in many cellular functions such as in protein synthesis, metabolism and as precursors of different hormones. Translocation of amino acids and derivatives thereof across biological membranes is mediated by amino acid transporters. 4F2hc-LAT1 is a heterodimeric amino acid transporter that is composed of two subunits belonging to the SLC3 (4F2hc) and SLC7 (LAT1) solute carrier families. The ancillary protein 4F2hc is responsible for the correct trafficking and regulation of the transporter LAT1. Preclinical studies have identified 4F2hc-LAT1 as a valid anticancer target due to its importance in tumor progression. The scintillation proximity assay (SPA) is a valuable radioligand binding assay that allows the identification and characterization of ligands of membrane proteins. Here, we present a SPA ligand binding study using purified recombinant human 4F2hc-LAT1 protein and the radioligand [3H]L-leucine as tracer. Binding affinities of different 4F2hc-LAT1 substrates and inhibitors determined by SPA are comparable with previously reported K m and IC 50 values from 4F2hc-LAT1 cell-based uptake assays. In summary, the SPA is a valuable method for the identification and characterization of ligands of membrane transporters including inhibitors. In contrast to cell-based assays, where the potential interference with other proteins such as endogenous transporters persists, the SPA uses purified protein making target engagement and characterization of ligands highly reliable

Implant-Based Breast Reconstruction after Mastectomy, from the Subpectoral to the Prepectoral Approach: An Evidence-Based Change of Mind?
Over the last years, prepectoral implant-based breast reconstruction has undergone a
renaissance due to several technical advancements regarding mastectomy techniques and surgical
approaches for the placement and soft tissue coverage of silicone implants. Initially abandoned due
to the high incidence of complications, such as capsular contraction, implant extrusion, and poor
aesthetic outcome, the effective prevention of these types of complications led to the prepectoral
technique coming back in style for the ease of implant placement and the conservation of the
pectoralis muscle function. Additional advantages such as a decrease of postoperative pain, animation
deformity, and operative time contribute to the steady gain in popularity. This review aims to
summarize the factors influencing the trend towards prepectoral implant-based breast reconstruction
and to discuss the challenges and prospects related to this operative approach
Efficacy of Cyclooctadepsipeptides and Aminophenylamidines against Larval, Immature and Mature Adult Stages of a Parasitologically Characterized Trichurosis Model in Mice
The genus Trichuris includes parasites of major relevance in veterinary and
human medicine. Despite serious economic losses and enormous impact on public
health, treatment options against whipworms are very limited. Additionally,
there is an obvious lack of appropriately characterized experimental infection
models. Therefore, a detailed parasitological characterization of a Trichuris
muris isolate was performed in C57BL/10 mice. Subsequently, the in vivo
efficacies of the aminophenylamidines amidantel, deacylated amidantel (dAMD)
and tribendimidine as well as the cyclooctadepsipeptides emodepside and in
particular PF1022A were analyzed. This was performed using various
administration routes and treatment schemes targeting histotropic and further
developed larval as well as immature and mature adult stages. Duration of
prepatent period, time-dependent localization of larvae during period of
prepatency as well as the duration of patency of the infection were determined
before drugs were tested in the characterized trichurosis model. Amidantel
showed no effect against mature adult T. muris. Tribendimidine showed
significantly higher potency than dAMD after oral treatments (ED50 values of
6.5 vs. 15.1 mg/kg). However, the opposite was found for intraperitoneal
treatments (ED50 values of 15.3 vs. 8.3 mg/kg). When emodepside and PF1022A
were compared, the latter was significantly less effective against mature
adults following intraperitoneal (ED50 values of 6.1 vs. 55.7 mg/kg) or
subcutaneous (ED50 values of 15.2 vs. 225.7 mg/kg) administration. Only
minimal differences were observed following oral administration (ED50 values
of 2.7 vs. 5.2 mg/kg). Triple and most single oral doses with moderate to high
dosages of PF1022A showed complete efficacy against histotropic second stage
larvae (3 Ă 100 mg/kg or 1 Ă 250 mg/kg), further developed larvae (3 Ă 10
mg/kg or 1 Ă 100 mg/kg) and immature adults (3 Ă 10 mg/kg or 1Ă100 mg/kg).
Histotropic first stage larvae were only eliminated after three doses of
PF1022A (3 Ă 100 mg/kg) but not after a single dose. These results indicate
that the cyclooctadepsipeptides are a drug class with promising candidates for
further evaluation for the treatment of trichurosis of humans and livestock
animals in single dose regimens
Flexural Fatigue Behavior of an EBC CMC Composite System In Air and Steam at High Temperature
Both coated and uncoated SiCSiC ceramic matrix composite (CMC) samples were tested in flexure under sustained peak low cycle fatigue (SPLCF) conditions in air or steam at elevated temperatures. The SiCSiC composites were reinforced with 2-D plies of boron nitride coated Hi-Nicalon Type-S SiC fibers which were woven as 5 harness satin (5HS) cloth. The composites were densified by chemical vapor infiltration (CVI) followed by slurry melt infiltration (SMI). A multilayer barium strontium aluminosilicate (BSAS) coating was applied to the samples by a plasma spray method. Fatigue loading limits were determined from monotonic flexure tests at room temperature and 1200oC. Stress levels under the proportional limit of the composite material were selected for the SPLCF tests. After cyclic testing, the composites were evaluated to determine crack propagation and failure modes in the coated and uncoated composites. Microstructural examination was used to identify coating degradation and failure modes of the EBCCMC system

The definitive version was published in Journal of Geophysical Research-Solid Earth 124(7), (2019): 6625-6652, doi: 10.1029/2019JB017611.The Southeastern United States is an ideal location to understand the interactions between mountain building, rifting, and magmatism. Line 2 of the Suwannee suture and Georgia Rift basin refraction seismic experiment in eastern Georgia extends 420 km from the Inner Piedmont to the Georgia coast. We model crustal and upper mantle VP and upper crustal VS. The most dramatic model transition occurs at the HigginsâZietz magnetic boundary, north of which we observe higher upper crustal VP and VS and lower VP/VS. These observations support the interpretation of the HigginsâZietz boundary as the Alleghanian suture. North of this boundary, we observe a lowâvelocity zone less than 2 km thick at ~5âkm depth, consistent with a layer of sheared metasedimentary rocks that forms the Appalachian detachment. To the southeast, we interpret synrift sediments and decreasing crustal thickness to represent crustal thinning associated with the South Georgia Rift Basin and subsequent continental breakup. The correspondence of the northern limit of thinning with the interpreted suture location suggests that the orogenic suture zone and/or the Gondwanan crust to the south of the suture helped localize subsequent extension. Lower crustal VP and VP/VS preclude volumetrically significant mafic magmatic addition during rifting or associated with the Central Atlantic Magmatic Province. Structures formed during orogenesis and/or extension appear to influence seismicity in Georgia today; earthquakes localize along a steeply dipping zone that coincides with the northern edge of the South Georgia Basin and the change in upper crustal velocities at the HigginsâZietz boundary.The SUGAR experiment would not have been possible without the help of local landowners, county and state officials, the University of Texas El Paso seismic source facility, IRIS PASSCAL instrument center, and the team of students who scouted, deployed, and recovered the geophones. We thank Jim Knapp, Susie Boote, and Ross Cao for helpful discussion and providing the sonic log data from GGSâ3080; Lindsay Worthington for discussion and sharing codes; Bradley Hacker and Mark Behn for sharing their lower crust velocity constraints; Emily Hopper and Karen Fischer for discussions; and Fred Cook for an image of processed COCORP data.
