scar ECM biophysical properties evolve from the acute to chronic stages of MI. The obtained information will help establish a knowledge basis about the dynamics of scar ECM to better understand post-MI cardiac remodeling.Advanced neck finite element modeling and development of neck injury criteria are important for the design of optimal neck protection systems in automotive and other environments. They are also important in virtual tests. The objectives of the present study were to develop a detailed finite element model (FEM) of the human neck and couple it to the existing head model, validate the model with kinematic data from legacy human volunteer and human cadaver impact datasets, and derive lateral impact neck injury risk curves using survival analysis from the upper and lower neck forces and moments. The detailed model represented the anatomy of a young adult mid-size male. It included all the cervical and first thoracic vertebrae, intervening discs, upper and lower spinal ligaments, bilateral facet joints, and passive musculature. Material properties were obtained from literature. Frontal, oblique, and lateral impacts to the distal end of the model was applied based on human volunteer and human cadaver experimental davailable in published literatures, and they can be used in virtual testing and advancing restraint systems for improving human safety.A comprehensive characterization was performed to investigate the composition and mineralogy of soils from a gold mining region and their correlation with arsenic (As) total concentration and its bioaccessible fraction. The arsenic bioaccessible (BAC) fraction was determined through in vitro test and calculated as the ratio between the amounts of As released and the total As concentration in the soil sample. Among the minor constituents of environmental concern, only arsenic is significantly higher (median of 748.0 mg kg-1) than the national guidelines (agricultural, 35 mg kg-1 and residential, 55 mg kg-1). All the other trace elements showed concentrations below the investigation values established for residential areas. The mean bioaccessible As was 7.0 mg kg-1, with a median value of 4.4 mg kg-1, and a median As BAC percentage of 0.7%. The Brunauer-Emmett-Teller (BET) surface area showed a consistent increase with the increase of the acid-soluble Al content in the soil samples. The distribution of As in the soil samples is not correlated with the abundance of As-minerals and the fraction of adsorbed As. Arsenic was shown to be trapped in oriented aggregates of crystalline (Al-)Fe-(hydr)oxides nanoparticles (the main metalloid reservoirs), as demonstrated by scanning and transmission electron microscopy analyses. This unique pattern supports the significant difference between total As concentration and the bioaccessible amount. There was a positive correlation between soluble Al (within the Fe-(hydr)oxides phases and minor gibbsite) and As concentration in the soil samples, and a negative correlation with bioaccessible As. Therefore, although Al in the soil is associated with high As levels, it also makes the metalloid less bioaccessible. The risk to human health from As exposure to these soils is low.Historical variations (1966-2016) in the exposure to inorganic elements in raptors of South West Spain have been little studied. Therefore, uncertainty exists concerning whether environmental or anthropogenic inputs, as well as dietary strategy shift, may cause changes in exposure patterns. To address this gap, essential and non-essential inorganic elements were measured in Common kestrel (Falco tinnunculus) feathers from museum specimens and free-living individuals spanning a 50-year period. Moreover, stable isotopes of δ13C and δ15N were also measured as proxies of Common kestrel feeding ecology over time. In general, all elements showed significant increasing trends overtime, suggesting changes of inputs from local sources. Moreover, δ15N signatures were correlated to the variations in Al, Cr, Cu, Fe, K, Li, Mg, Mn, Ni, P, Pb, Rb, Sr, Ti, V and Zn concentrations, suggesting trophic changes in this kestrel population as well as possible biomagnification processes. Finally, some values of Cr, Mn and Pb were above the threshold concentrations of potential toxicity.

To compare time spent on day of surgery and post-surgical outcomes for sialendoscopy procedures at an ambulatory surgery center versus in a hospital operating room.

Retrospective chart review for patients who underwent sialendoscopy for sialadenitis or sialolithiasis from March 2017 to May 2020 were included. Surgery location (ambulatory surgery center or hospital operating room) was compared. Primary outcomes included total time in hospital, operative time, total time in operating room. and recovery time. Secondary outcomes included rate of symptoms resolutions, requiring further medical management, and requiring further surgical intervention.

A total of 321 procedures were included. Sialendoscopy in an ambulatory surgery center compared to main operating room decreased median hospital time (166min reduction, p<0.001), operative time (18min reduction, p<0.001), total time in operating room (34min reduction, p<0.001), and recovery time (64min reduction, p<0.001). Sialendoscopy in an ambulatory surgery center had similar rates of post-operative resolution of symptoms and further medical or surgical intervention compared to procedures in a hospital operating room.

Sialendoscopy can be safely performed in an ambulatory surgery center for sialadenitis or appropriate sialolithiasis cases while decreasing hospital time, operative time, total time in operating room time, and recovery time.

Women of childbearing age are the predominate population affected by SLE. In this study, we generated an iPS cell line from a 30-year-old female who was pregnant with a gestational age of 27 weeks and diagnosed with severe preeclampsia, SLE and psoriasis. this website This patient-specific iPSC line will be useful to create the specific disease model of systemic lupus erythematosus to elucidate the pathological mechanisms and develop drug screening.
