ing the knee and ankle joints. Together with the observed findings on ankle and knee muscle co-contraction, it is essential to change running shoes after a long wearing time in both healthy and genu varus females.The human visual system is continuously exposed to a natural environment with static and moving objects that the visual system needs to continuously integrate and process. Glass patterns (GPs) are a class of visual stimuli widely used to study how the human visual system processes and integrates form and motion signals. GPs are made of pairs of dots that elicit a strong percept of global form. A rapid succession of unique frames originates dynamic GPs. Previous psychophysical studies showed that dynamic translational GPs are easier to detect than the static version because of the spatial summation across the unique frames composing the pattern. GSK046 purchase However, it is not clear whether the same mechanism is involved in dynamic circular GPs. In the present study, we psychophysically investigated the role of the temporal and spatial summation in the perception of both translational and circular GPs. We manipulated the number of unique frames in dynamic GPs and the update rate of the frames presentation. The results suggest that spatial and temporal summation across unique frames takes place for both translational and circular GPs. Moreover, the number of unique frames and the pattern update rate equally influence the discrimination thresholds of translational and circular GPs. These results show that form and motion integration is likely to be processed similarly for translational and circular GPs.

In 2017, the American College of Cardiology/ American Heart Association (ACC/AHA) guidelines redefined the threshold of high blood pressure (BP) for non-pregnant adults. Several studies aimed to determine whether lowering these thresholds should be considered for pregnancies to prevent poor neonatal outcomes, but the results were inconclusive.

We perform a systematic review and meta-analysis to evaluate the association between BP groups defined by the 2017 ACC/AHA guidelines and pregnancy outcomes. Relevant literature was searched in PubMed, Google Scholar, Embase, and Web of Science up to 18 May 2021.

Sixteen eligible studies from twelve articles with a total of 303,131 pregnancies were identified, encompassing 233,084, 20,859, 39,379 individuals with normal BP, elevated BP, and stage 1 hypertension, respectively. When compared with normal BP, the combined odds ratio (95% confidence interval) of elevated BP for adverse pregnancy outcomes was not significant; whereas, that of stage 1 hypertension were 1.25 (1.13-1.39), 1.16 (1.03-1.31), 1.50 (1.28-1.77) and 1.12 (1.00-1.25) for preterm delivery, small for gestational age, low birth weight, and early-term delivery, respectively.

Our results indicated that stage 1 hypertension increased the risk of poor neonatal outcomes, highlighting the importance of recognition of stage 1 hypertension as a risk indicator for poor pregnancy outcomes.

Musculoskeletal (MSK) models based on literature data are meant to represent a generic anatomy and are a popular tool employed by biomechanists to estimate the internal loads occurring in the lower limb joints, such as joint reaction forces (JRFs). However, since these models are normally just linearly scaled to an individual's anthropometry, it is unclear how their estimations would be affected by the personalization of key features of the MSK anatomy, one of which is the femoral version angle.

How are the lower limb JRF magnitudes computed through a generic MSK model affected by changes in the femoral version?

We developed a bone-deformation tool in MATLAB (shared at https//simtk.org/projects/bone_deformity) and used it to create a set of seven OpenSim models spanning from 2˚ femoral retroversion to 40˚ anteversion. We used these models to simulate the gait of an elderly individual with an instrumented prosthesis implanted at their knee joint (5th Grand Challenge dataset) and quantified both the changK anatomical features might be necessary for accurate estimation of JRFs with these models.During the winemaking process, fining materials derived from milk and egg products are traditionally used to remove undesirable substances to reduce bitterness and astringency. The possible residues of allergens in treated wine may pose a potential risk for allergy patients. In this study, we developed a method for the simultaneous quantification of eight allergens (αS1-casein, αS2-casein, β-casein, κ-casein, β-lactoglobulin, lysozyme, ovalbumin and ovotransferrin) in red wine by ultrahigh-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS). The sample was extracted with polyvinylpolypyrrolidone (PVPP) solution, following trypsin digestion and peptide-level purification by solid-phase extraction (SPE). A strategy based on standard addition was used for the accurate quantification of the target allergens in wine products. The limits of detection (LODs) were shown to be 0.003-0.015 μg/mL for milk allergens and 0.1 μg/mL for egg allergens. This economical and reliable method would be appropriate for routine analysis and further allergen label management for red wine.Hepatolenticular degeneration (HLD) is an inherited disorder associated with human copper metabolism. Gandou decoction (GDD), a traditional Chinese medicinal formula, has been used as a therapeutic agent for the treatment of HLD in China for decades. Recent pharmacological evaluation in our laboratory has demonstrated that GDD exerts positive and beneficial effects on HLD model rats. However, its underlying therapeutic mechanisms are not yet well understood. To explore the potential therapeutic effects of GDD against HLD, liver and urine metabolomics approach combined with histopathological examination were performed to reveal the underlying mechanisms. Changes in metabolic profiles were estimated by ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) coupled with multivariate statistical analyses. The results indicated that GDD could significantly improve liver pathological variations. Moreover, 19 and 11 significantly altered metabolites were found in the liver and urine between the normal and model groups, respectively.
