Serum metabolomic markers of the Dietary Approaches to Stop Hypertension (DASH) diet are previously reported. In an independent study, the similarity of urine metabolomic markers are investigated.
In the DASH-Sodium trial, participants are randomly assigned to the DASH diet or control diet, and received three sodium interventions (high, intermediate, low) within each randomized diet group in random order for 30 days each. Urine samples are collected at the end of each intervention period and analyzed for 938 metabolites. Two comparisons are conducted 1) DASH-high sodium (n = 199) versus control-high sodium (n = 193), and 2) DASH-low sodium (n = 196) versus control-high sodium. Significant metabolites identified using multivariable linear regression are compared and the top 10 influential metabolites identified using partial least-squares discriminant analysis to the results from the DASH trial. Nine out of 10 predictive metabolites of the DASH-high sodium and DASH-low sodium diets are identical. Most candidate biomarkers from the DASH trial replicated. N-methylproline, chiro-inositol, stachydrine, and theobromine replicated as influential metabolites of DASH diets.
Candidate biomarkers of the DASH diet identified in serum replicated in urine. Replicated influential metabolites are likely to be objective biomarkers of the DASH diet.

To determine the effects of systematic calcitonin administration on post-orthodontic relapse in rat model.
This experimental animal model involved 36 male Wister rats. check details The maxillary right first molars were moved mesially, using a modified orthodontic appliance delivered 50 gm, for 14 days, retained for 4 days and left to relapse for 10 days. The study group was divided into three subgroups in which a single injection of calcitonin (20 IU/Kg), three injections of calcitonin (20 IU/Kg), each every other day, and normal saline were administered subcutaneously after orthodontic tooth movement has finished. The relapse ratio, histomorphometric analysis including osteoblasts, osteoclasts numbers and bone area and immunohistochemical analysis including the expression of receptor activator of nuclear factor kappa Β (RANK), receptor activator of nuclear factor kappa Β ligand (RANKL) and osteoprotegerin (OPG) were measured and assessed.
The relapse ratio was significantly reduced in the three-dose calcitonin group (28%) compared to the single dose calcitonin group (34%) and the control group (46%). This was accompanied by a nonsignificant increase in osteoblasts number and bone area in three-dose calcitonin group and a nonsignificant reduction in osteoclast number. However, the immune histochemical expression of RANK, RANKL and OPG did not show statistically significant difference at the end of relapse period.
Systemic administration of three doses of calcitonin may minimize the relapse ratio in experimentally moved rat molars.

Here, we identify Tnfaip2 as an inhibitor of reprogramming of mouse fibroblasts into induced pluripotent stem cells. Tnfaip2 knockout impairs differentiation of embryonic stem cells (ESCs), and knockdown of the planarian para-ortholog, Smed-exoc3, abrogates in vivo tissue homeostasis and regeneration-processes that are driven by somatic stem cells. When stimulated to differentiate, Tnfaip2-deficient ESCs fail to induce synthesis of cellular triacylglycerol (TAG) and lipid droplets (LD) coinciding with reduced expression of vimentin (Vim)-a known inducer of LD formation. Smed-exoc3 depletion also causes a strong reduction of TAGs in planarians. The study shows that Tnfaip2 acts epistatically with and upstream of Vim in impairing cellular reprogramming. Supplementing palmitic acid (PA) and palmitoyl-L-carnitine (the mobilized form of PA) restores the differentiation capacity of Tnfaip2-deficient ESCs and organ maintenance in Smed-exoc3-depleted planarians. Together, these results identify a novel role of Tnfaip2 and exoc3 in controlling lipid metabolism, which is essential for ESC differentiation and planarian organ maintenance.Coronavirus disease 2019 (COVID-19) has been an unprecedented and continuously evolving healthcare crisis. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) spread rapidly and initially little was known about the virus or the clinical course for infected children. In the United States of America, the medical response has been regionalized, based on variation in community transmission of the virus and localized outbreaks. Pediatric pulmonary and sleep divisions evolved in response to administrative and clinical challenges. As the workforce transitioned to working remotely, video conferencing technology and multicenter collaborative efforts were implemented to create clinical protocols. The COVID-19 pandemic challenges the framework of current medical practice but also highlights the dynamic and cooperative nature of pediatric pulmonology and sleep medicine. Our response to this pandemic has laid the groundwork for future challenges.Eighty-seven percent of a large sample of children with autism spectrum disorder (ASD) are at risk for motor impairment (Bhat, Physical Therapy, 2020, 100, 633-644). In spite of the high prevalence for motor impairment in children with ASD, it is not considered among the diagnostic criteria or specifiers within DSM-V. In this article, we analyzed the SPARK study dataset (n = 13,887) to examine associations between risk for motor impairment using the Developmental Coordination Disorder-Questionnaire (DCD-Q), social communication impairment using the Social Communication Questionnaire (SCQ), repetitive behavior severity using the Repetitive Behaviors Scale - Revised (RBS-R), and parent-reported categories of cognitive, functional, and language impairments. Upon including children with ASD with cognitive impairments, 88.2% of the SPARK sample was at risk for motor impairment. The relative risk ratio for motor impairment in children with ASD was 22.2 times greater compared to the general population and that risk communication, repetitive behavior, cognitive, and functional impairment. It is important to recognize motor impairments as one of the diagnostic criteria or specifiers for ASD and there is a need to administer appropriate motor screening, assessment, and interventions in children with ASD.With the development of positive psychology, gratitude, as a typical positive emotion, has attracted significant attention. Gratitude has a profoundly positive effect on cultivating people's positive traits, and negative emotions affect many aspects of people's daily lives. Many studies have explored the inhibiting effect of gratitude on negative emotions. In this study, based on the coping theory and the broaden-and-build theory of positive emotion, we used scenario method to discuss the inhibiting effect of trait gratitude and state gratitude on a common and typical negative emotion situational envy. We randomly recruited 326 undergraduate students as participants and asked them to complete the Gratitude Questionnaire, Dispositional Envy Scale, state gratitude materials, and situational envy materials. Our results showed that (1) state gratitude inhibits situational envy and (2) state gratitude plays a partial mediating role between trait gratitude and situational envy. This article suggests educational field for future school should devote more attention to gratitude, and lay a good foundation for students' future development in society. Taken together, these results verify the positive role of gratitude, help to expand relevant theories about inhibiting envy, and provide a theoretical reference for cultivating people's positive traits and countering negative emotions.
The aim of this study was to determine the demographic profile of driver gene alterations, especially low-frequency gene alterations in Chinese patients with non-small cell lung cancer (NSCLC).
A total of 7395 Chinese patients with NSCLC were enrolled in the study. Next-generation sequencing (NGS) was performed on formalin-fixed paraffin-embedded specimens collected via either surgical resection or biopsy.
The frequent genomic alterations found in the study were EGFR mutations (51.7%), KRAS mutations (13.1%), MET alterations (5.6%; 3.2% copy number gains and 0.5% exon 14 skipping mutation), HER2 alterations (7.0%; 2.0% copy number gains and 5.4% mutations), ALK alterations (7.2%; 3.9% rearrangements), RET rearrangements (1.4%), ROS1 rearrangements (0.9%), and NTRK rearrangements (0.6%). The EGFR mutation rate was found to be significantly higher in women than in men (69.1% vs. 38.5%, P < 0.001), while the KRAS mutation (17.5% vs. 7.3%, P < 0.001) and MET alteration rates (6.5% vs. 4.5%, P < 0.0 the frequency of different driver genes was diverse in different age-gender groups. What this study adds It may enable clinicians to make clinical decisions, and assist government, pharmaceutical researchers and insurance companies develop public healthcare strategies.
To assess the efficacy and safety of glucose-lowering drugs used as an adjunct to insulin therapy in adults with type 1 diabetes.
We searched Medline, Embase and the Cochrane Central Register of Controlled Trials up to 24 January 2020 for randomized controlled trials. Our primary outcome was change in HbA1c. We additionally assessed eight efficacy and six safety secondary endpoints. We performed random effects frequentist network meta-analysis to estimate mean differences (MDs) and odds ratios (ORs), alongside 95% confidence intervals (CIs). We assessed risk of bias and evaluated confidence in the evidence for the primary outcome.
We included 58 trials comprising 13 216 participants. Overall, sodium-glucose co-transporter (SGLT) inhibitors, liraglutide, glibenclamide, acarbose and metformin reduced HbA1c compared with placebo (MDs ranging from -0.46% [95% CI -0.64% to -0.29%] for empagliflozin to -0.20% [-0.35% to -0.06%] for metformin). SGLT inhibitors, exenatide daily, liraglutide and metformin reduceowever, low quality of evidence and an increased risk of diabetic ketoacidosis, genital infections or gastrointestinal adverse events should be taken into consideration by healthcare providers and patients. Future long-term trials are needed to clarify their benefit-to-risk profile and elucidate their role in clinical practice.Plant diversity and plant-consumer/pathogen interactions likely interact to influence ecosystem carbon fluxes but experimental evidence is scarce. We examined how experimental removal of foliar fungi, soil fungi and arthropods from experimental prairies planted with 1, 4 or 16 plant species affected instantaneous rates of carbon uptake (GPP), ecosystem respiration (Re ) and net ecosystem exchange (NEE). Increasing plant diversity increased plant biomass, GPP and Re , but NEE remained unchanged. Removing foliar fungi increased GPP and NEE, with the greatest effects at low plant diversity. After accounting for plant biomass, we found that removing foliar fungi increased mass-specific flux rates in the low-diversity plant communities by altering plant species composition and community-wide foliar nitrogen content. However, this effect disappeared when soil fungi and arthropods were also removed, demonstrating that both plant diversity and interactions among consumer groups determine the ecosystem-scale effects of plant-fungal interactions.
