Furthermore, the relationships between gene expression and lipid/fatty acid accumulation and some candidate key lipid genes were discussed.

This study provided the global patterns of fatty acid and lipid biosynthesis-related gene expression, which are critical to understanding the molecular basis of lipid biosynthesis and identifying the lipid accumulation rate-limiting genes during seed development.

The purpose of this study was to identify symptom profiles among U.S. military personnel within 1year after combat injury and assess the relationship between the symptom profiles and long-term quality of life (QoL).

The study sample consisted of 885 military personnel from the Expeditionary Medical Encounter Database who completed (1) a Post-Deployment Health Assessment (PDHA) within 1year following combat injury in Iraq or Afghanistan, and (2) a survey for the Wounded Warrior Recovery Project (WWRP), a longitudinal study tracking patient-reported outcomes (e.g., QoL) in injured military personnel. Fifteen self-reported symptoms from the PDHA were assessed using latent class analysis to develop symptom profiles. Multivariable linear regression assessed the predictive effect of symptom profiles on QoL using the physical (PCS) and mental (MCS) component summary scores from the 36-Item Short Form Survey included in the WWRP. Time between PDHA and WWRP survey ranged from 4.3 to 10.5years (M = 6.6, SD = 1.3).

Prognosis in ANCA-associated vasculitis (AAV) has greatly improved with immunosuppressive use whereas incidence of treatment-related comorbidities such as osteoporosis has increased. However, studies investigating bone disease in AAV are limited. Fracture Risk Assesment Tool (FRAX) was developed to estimate 10-year hip and major osteoporotic fracture risks. Aim of this study was to estimate FRAX scores in AAV patients and compare them to healthy controls.

30 AAV patients and 20 healthy controls were included. Demographic, disease, and medication history were recorded from patient files. Femoral neck, lumbar spine and forearm bone mineral densitometry, and thoracolumbar radiographs were performed. FRAX fracture risk scoring was assessed for all participants.

There were 18 male and 12 female patients. Mean age was 58.5 ± 11.7years. Osteoporosis and osteopenia were present in 23.3% and 50% of patients, respectively. There were fractures in eight patients (26.7%). FRAX major fracture (9.4 ± 7.3% vs 5.9 ± 3.2%, p = 0.02) and hip fracture (2.2 ± 3.2% vs 0.9 ± 0.8%, p = 0.03) scores were higher in patients than controls. In seven (23.3%) patients, the 10-year probability of hip fracture was  ≥ 3% and in five (16%) patients the 10-year risk of a major osteoporosis-related fracture was  ≥ 20%. None of the controls exceeded these thresholds.

AAV patients are at high risk for future fractures as calculated with FRAX. Life-long monitoring for bone disease and fractures are essential. Large studies with longer follow-up are needed to determine the accuracy of FRAX risk scoring in predicting fractures.

Moderate-to-high correlations have been reported between the [
C]PiB PET-derived relative tracer delivery rate R
and relative CBF as measured using [
O]H
O PET, supporting its use as a proxy of relative CBF. As longitudinal PET studies become more common for measuring treatment efficacy or disease progression, it is important to know the intrinsic variability of R
. The purpose of the present study was to determine this through a retrospective data analysis.

Test-retest data belonging to twelve participants, who underwent two 90 min [
C]PiB PET scans, were retrospectively included. The voxel-based implementation of the two-step simplified reference tissue model with cerebellar grey matter as reference tissue was used to compute R
images. Next, test-retest variability was calculated, and test and retest R
measures were compared using linear mixed effect models and a Bland-Altman analysis.

Test-retest variability was low across regions (max. 5.8 %), and test and retest measures showed high, significant correlations (R
=0.92, slope=0.98) and a negligible bias (0.69±3.07 %).

In conclusion, the high precision of [
C]PiB R
suggests suitable applicability for cross-sectional and longitudinal studies.

The Watchman and the Amulet are the two most frequently used devices for LAAC but no randomized study has so far assessed their comparative leak rates after intervention. The "Comparison of Amplatzer Amulet vs Watchman devices in patients undergoing left atrial appendage closure" (Swiss-Apero, clinicaltrial.gov NCT03399851) is an academic-sponsored multicenter, randomized clinical trial comparing Amulet versus Watchman/FLX devices among patients undergoing a clinically indicated LAAC. The study is designed to assess the superiority of Amulet vs. Watchman/FLX in terms of leaks detected by cardiac computed tomography angiography (CCTA) at 45 days (primary endpoint) and 13 months (secondary endpoint) after intervention by an imaging Core Laboratory. The Swiss-Apero study is the first randomized clinical trial comparing Amulet and Watchman/FLX with respect to the prevalence of post-procedural leak as assessed with CCTA.Pulpitis is a complicated chronic inflammatory process which can be in a dynamic balance between damage and repair. The extracellular matrix plays an important regulatory role in wound healing and tissue repair. The aim of this study was to explore the role of the epigenetic mark, enhancer of zeste homolog 2 (EZH2) on the degradation of extracellular matrix during pulpitis. Quantitative polymerase chain reaction was used to assess the expression of matrix metalloproteinases (MMPs) and type I collagen in human dental pulp cells (HDPCs) upon EZH2 and EI1 (EZH2 inhibitor) stimulation. The mechanism of EZH2 affecting extracellular matrix was explored through quantitative polymerase chain reaction and Western blot. A rat model of dental pulp inflammation was established, and the expression of type I collagen in dental pulp under EZH2 stimulation was detected by immunohistochemical staining. EZH2 upregulated the expression of MMP-1, MMP-3, MMP-8, and MMP-10 and decreased the production of type I collagen in HDPCs, while EI1 had the opposite effect.
