The etiology of patellofemoral pain has remained elusive, potentially due to an incomplete understanding of how pain, motor control, and kinesiophobia disrupt central nervous system functioning.

To directly evaluate brain activity during experimental knee pain and its relationship to kinesiophobia in patients with patellofemoral pain.

Cross-sectional.

Young females clinically diagnosed with patellofemoral pain (n = 14; 14.4 [3.3]y; body mass index = 22.4 [3.8]; height = 1.61 [0.1]m; body mass = 58.4 [12.7]kg). A modified Clarke test (experimental pain condition with noxious induction via patella pressure and quadriceps contraction) was administered to the nondominant knee (to minimize limb dominance confounds) of patients during brain functional magnetic resonance imaging (fMRI) acquisition. Patients also completed a quadriceps contraction without application of external pressure (control contraction). Kinesiophobia was measured using the Tampa Scale of Kinesiophobia. The fMRI analyses assessed brain ted with alterations in central nociceptive processing. These findings may provide novel complementary pathways for targeted restoration of patient function.

The single hop for distance (SHD) and Limb Symmetry Index are often used to assess readiness for returning to sport postinjury. However, the sensitivity of SHD Limb Symmetry Index for detecting functional abnormalities is questionable due to the methodological inconsistencies in the literature. The common methods use few repetitions; lacking consideration of repeated maximum performance, or the effect of fatigue (or failed attempts) on repeated maximum performance, required for sport. The objectives were to review the SHD for evaluating repeated maximum performance, and the effect of failed attempts on consistency of performance, in a healthy population of sportspersons.

A quantitative, nonexperimental, same-subject, repeated-measures design with 15 healthy Cardiff University students.

Participants performed the SHD up to 30 times on each limb, with standardized rests. A failed attempt, if the landing was not controlled, was noted but distance not recorded. Participants stopped if 3 consecutive distanceHD is not achieved until multiple repetitions have been conducted. Repeated maximum performance does not drop-off until over 21 repetitions have been conducted. Consistency of repeated maximum performance varies depending on whether failed attempts are included in the analysis. Further investigation into the reasons for failed attempts is required to improve clinical decision making for return to sport postinjury.Transition from professional sport to nonsport endeavors has implications for postcareer health and well-being of athletes. The purpose of the current study was to examine associations among transition-related psychosocial factors and current mental health outcomes in former National Football League (NFL) players. Participants were former NFL players (n = 1,784; mean age = 52.3 ± 16.3 years) who responded to a questionnaire assessing the nature of their discontinuation from professional football (i.e., any degree of voluntary choice vs. forced discontinuation), prediscontinuation transition planning (yes vs. no), and current symptoms of depression and anxiety. After adjusting for relevant covariates, having an involuntary discontinuation and no transition plan prior to discontinuation were associated with greater depressive and anxiety symptom severity. Autonomy in discontinuation and pretransition planning are important to former NFL football players' mental health. Increasing autonomy in the discontinuation decision and pretransition planning represent psychoeducational intervention targets for this population.
The study aimed to examine predicted differences of 2 different behavior change patterns on physical fitness (PF).

Participants were 241 students (51% girls) aged 11-14years from China. Light physical activity, moderate to vigorous physical activity (MVPA), and sedentary behavior (SB) were objectively measured. Sleep was obtained by subtracting from awake time. According to Chinese National student PF standards, 5 components of PF, including body mass index, cardiorespiratory fitness, speed, muscular explosive power and strength endurance, and flexibility, were assessed. The effects of different time reallocations between 24-hour movement behaviors on PF were estimated based on adjusted compositional multiple linear regression models with isometric log ratios.

Compared with MVPA substituting for the remaining behaviors, MVPA replacing SB or light physical activity produced more favorable changes on the comprehensive PF score, cardiorespiratory fitness, explosive power, and speed. MVPA replacing 30minutes of SB was associated with favorable changes in PF (+1.9 [0.53, 3.18] points), 50-m run (-0.17 [-0.31, -0.04] s), long-distance running (-5.54s [for girls]/7.25s [for boys]), and long jump (+0.05 [0.01, 0.09] m). When sleep replaced SB, PF improved.

MVPA substituting SB or light physical activity is a strategy with a greater improvement in PF.

We propose that food first should mean "where practically possible, nutrient provision should come from whole foods and drinks rather than from isolated food components or dietary supplements." There are many reasons to commend a food first strategy, including the risk of supplement contamination resulting in anti-doping violations. However, a few supplements can enhance health and/or performance, and therefore a food only approach could be inappropriate. We propose six reasons why a food only approach may not always be optimal for athletes (a) some nutrients are difficult to obtain in sufficient quantities in the diet, or may require excessive energy intake and/or consumption of other nutrients; (b) some nutrients are abundant only in foods athletes do not eat/like; (c) the nutrient content of some foods with established ergogenic benefits is highly variable; (d) concentrated doses of some nutrients are required to correct deficiencies and/or promote immune tolerance; (e) some foods may be difficult to consume immediately before, during or immediately after exercise; and (f) tested supplements could help where there are concerns about food hygiene or contamination. In these situations, it is acceptable for the athlete to consider sports supplements providing that a comprehensive risk minimization strategy is implemented. As a consequence, it is important to stress that the correct terminology should be "food first but not always food only."Accumulation of plastic waste is harming eco-systems and it is time to move towards a circular plastic economy. Sustainable production and recycling processes for plastics are challenged mostly by the lack of renewable building blocks. This study investigates hydrothermal processing (HTP) as a platform for depolymerization of two commonly used plastic polymers. Subcritical water (300 °C; 10 MPa) was tested as a solvent to treat polyethylene terephthalate (PET) and nylon-6 individually and in a mixture for a short reaction time of 90 min. Monomer recovery, gaseous emissions, and the effect of polymer mixture were evaluated by comprehensive analyses of all reaction products. Terephthalic acid (TPA), one of two monomers of PET was recovered as a solid product with a mass yield of 75%. ε-caprolactam (CPL), the single monomer of nylon-6 was recovered as a liquid product with a mass yield of 92.5%. Following PET + nylon-6 co-processing, TPA recovery decreased by 20%, whereas CPL recovery was not affected. Since TPA and CPL were recovered in different phases, an easy separation can likely be created for co-processing of PET and nylon-6. While most HTP studies neglect analysis of the gas phase, acetaldehyde and cyclopentene emissions were detected during HTP of PET and nylon-6, respectively. As shown here, gaseous emissions, which may be toxic, should be addressed in future developments of HTP for plastics. The results presented here can contribute to developing HTP processes for plastic recycling, that will be part of a circular plastic economy and a more sustainable future.At the time of writing, more than 440 million confirmed coronavirus disease 2019 (COVID-19) cases and more than 5.97 million COVID-19 deaths worldwide have been reported by the World Health Organization since the start of the outbreak of the pandemic in Wuhan, China. During the COVID-19 pandemic, many variants of SARS-CoV-2 have arisen because of high mutation rates. N501Y, E484K, K417N, K417T, L452R and T478K in the receptor binding domain (RBD) region may increase the infectivity in several variants of SARS-CoV-2. In this study, we discovered that GB-1, developed from Chiehyuan herbal formula which obtained from Tian Shang Sheng Mu of Chiayi Puzi Peitian Temple, can inhibit the binding between ACE2 and RBD with Wuhan type, K417N-E484K-N501Y and L452R-T478K mutation. In addition, GB-1 inhibited the binding between ACE2 and RBD with a single mutation (E484K or N501Y), except the K417N mutation. In the compositions of GB-1, glycyrrhizic acid can inhibit the binding between ACE2 and RBD with Wuhan type, except K417N-E484K-N501Y mutation. Our results suggest that GB-1 could be a potential candidate for the prophylaxis of different variants of SARS-CoV-2 infection because of its inhibition of binding between ACE2 and RBD with different mutations (L452R-T478K, K417N-E484K-N501Y, N501Y or E484K).Paeoniflorin is a water-soluble monoterpenoid glycoside that can be derived from multiple herbaceous plants, such as Radix Paeoniae Rubra, Radix Paeoniae Alba, Paeonia suffruticosa and Cimicifugae Foetidae. Multiple studies have suggested that Paeoniflorin possesses an excellent anti-tumor effect in variety of tumors, including liver cancer, gastric cancer, breast cancer, lung cancer, pancreatic cancer, colorectal cancer and bladder cancer. It can induce cell apoptosis, inhibit proliferation, invasion and metastasis via different molecular mechanisms, which are mainly involved in nuclear transcription factor kappα (NF-κB), B-cell lymphoma-2(Bcl-2) family, MicroRNA, neural precursor cell expressed developmentally down-regulated protein 4(NEDD4) signaling pathway, transcription activating factor (STAT3), p21, p53/14-3-3 signaling pathway, transforming growth factor-β1(TGF-β1)/Smads signaling pathway, Mitogen-activated protein kinase (MAPK) signaling pathway and Notch-1. Current studies on anti-tumor effect and mechanism of action of Paeoniflorin remain unclear. Therefore, this study reviews the research progress in the anti-tumor effect and mechanism of Paeoniflorin in an attempt to provide a new thought and theoretical basis for further development and clinical application of Paeoniflorin.
