Spermidine is a natural polyamine, central to cellular homeostasis and growth, that promotes macroautophagy/autophagy. The polyamine pathway is highly conserved from bacteria to mammals and spermidine (prominently found in some kinds of aged cheese, wheat germs, nuts, soybeans, and fermented products thereof, among others) is an intrinsic part of the human diet. Apart from nutrition, spermidine is available to mammalian organisms from intracellular biosynthesis and microbial production in the gut. MEK inhibitor Importantly, externally supplied spermidine (via drinking water or food) prolongs lifespan, activates autophagy, improves mitochondrial function, and refills polyamine pools that decline during aging in various tissues of model organisms, including mice. In two adjacent studies, we explored how dietary spermidine supplementation enhances eEF5/EIF5A hypusination, cerebral mitochondrial function and cognition in aging Drosophila melanogaster and mice.Mixed acute rejection is a clinicopathological entity that is difficult to accurately diagnose, and so may be under-reported. Allografts are lost more often than in either humoral or cellular rejection. The diagnosis requires both histological and immunological studies on renal biopsy and blood specimens from the transplant recipient to provide the required rescue therapy to abolish the allogeneic response against the graft. We present a clinical case report of an active mixed acute rejection driven by a de novo donor-specific complement-binding anti-DQB1*0301 antibody and intraepithelial CD8 T-cells in a patient with a kidney transplant. The patient was diagnosed, treated, and followed up as per the local institution's procedure with a full recovery of graft function. Our case emphasises the challenge of a mixed acute rejection and supports the view of the need to improve the post-transplant outcome of recipients and their grafts.Impact loading has been associated with running-related injuries, and gait retraining has been suggested as a means of reducing impact loading and lowering the risk of injury. However, gait retraining can lead to increased perceived awkwardness and effort. The influence of specifically trained and self-selected running gait modifications on acute impact loading, perceived awkwardness and effort is currently unclear. Sixteen habitual rearfoot/midfoot runners performed forefoot strike pattern, increased step rate, anterior trunk lean and self-selected running gait modifications on an instrumented treadmill based on real-time biofeedback. Impact loading, perceived awkwardness and effort scores were compared among the four gait retraining conditions. Self-selected gait modification reduced vertical average loading rate (VALR) by 25.3%, vertical instantaneous loading rate (VILR) by 27.0%, vertical impact peak (VIP) by 16.8% as compared with baseline. Forefoot strike pattern reduced VALR, VILR and peak tibial acceleration. Increased step rate reduced VALR. Anterior trunk lean did not reduce any impact loading. Self-selected gait modification was perceived as less awkward and require less effort than the specifically trained gait modification (p less then 0.05). These findings suggest that self-selected gait modification could be a more natural and less effortful strategy than specifically trained gait modification to reduce acute impact loading, while the clinical significance remains unknown.In this study, we aimed to investigate treatment options and the prognosis of patients with WM in China. This retrospective study included 1141 patients diagnosed with symptomatic WM between January 2003 and December 2019 at 35 tertiary hospitals in 22 provinces of China. Fifty-four patients (7.3%) received monotherapy, 264 (36.0%) received chemoimmunotherapy, 395 (53.8%) received other combination regimens without rituximab, and 21 (2.9%) received ibrutinib. Using a multivariable Cox regression model, age > 65 years old, platelets 65 years, LDH ≥250 IU/L, ALB less then 3.5 g/dl and β2 microglobulin ≥4 mg/L) together with PLT ≤ 100 × 109/L indicate a poor prognosis for patients with WM.To test predictions of the extended process model of emotion regulation, we conducted a pre-registered replication and extension of Sheppes et al.'s Study 3 ([2014]. Emotion regulation choice A conceptual framework and supporting evidence. Journal of Experimental Psychology General, 143(1), 163-181. doi10.1037/a0030831) on the effects of intensity and temporal goal on reappraisal choice. In the original study, participants chose reappraisal over distraction more in response to low intensity stimuli than high intensity stimuli and when given a long-term emotion regulation goal than an immediate emotion regulation goal. We attempted a replication in a larger sample and extended the research to test whether individual differences in the tendency to consider future consequences of one's actions (CFC) would moderate the effect of goal on emotion regulation choice. We replicated the effects of intensity, but not temporal goal, on choice. CFC interacted with temporal goal participants low in CFC chose reappraisal more often if given a short-term goal than a long-term goal, but participants high in CFC chose reappraisal more often if given a long-term goal than a short-term goal. Although the effects of temporal goal did not replicate, our results suggest that it may interact with individual differences to influence emotion regulation choice. These findings contribute to a growing interest in factors that influence emotion regulation behaviour.Emotion malleability beliefs, or beliefs that emotions are changeable versus fixed, may be an important and modifiable determinant of emotion regulation strategy employment and psychological distress. The present study evaluated the prospective relationship between college students' emotion malleability beliefs, depression and anxiety symptom severity, cognitive and behavioural avoidance, social engagement, and cognitive reappraisal. Participants were college students (N = 177) who completed a battery of questionnaires at the beginning of the academic year and again at a 6-month follow-up. Linear regression analyses indicated that emotion malleability beliefs predicted anxiety and depression, although this effect was not found when controlling for baseline symptom severity. Increases in emotion malleability beliefs were associated with more cognitive reappraisal and less cognitive and behavioural avoidance at follow-up when controlling for baseline levels of each variable. To the extent that emotion malleability beliefs predicted less avoidance at follow-up, anxiety and depression symptom severity was lower.
