Relationship between protein intake and PheOx.
<p>6 participants completed 34 metabolic trials with a range of test protein intake (0.2–2.8 g·kg<sup>-1</sup>·d<sup>-1</sup>). The breakpoint estimated the average protein requirement. The breakpoint was determined by using a biphasic linear regression crossover analysis. The average protein requirement and recommended protein intake were estimated to be 1.53, 1.70 g·kg<sup>-1</sup>·d<sup>-1</sup> respectively (R<sup>2</sup> = 0.85).</p

The effect of protein intake on phenylalanine fluxes.
<p>Values are means ± SD. No significant differences (P > 0.05) in phenylalanine flux were observed within each participant because of various test protein intakes.</p

Petasin Activates AMP-Activated Protein Kinase and Modulates Glucose Metabolism
Petasin (<b>1</b>), a natural
product found in plants of
the genus <i>Petasites</i>, has beneficial medicinal effects,
such as antimigraine and antiallergy activities. However, whether
or not <b>1</b> modulates metabolic diseases is unknown. In
this study, the effects of <b>1</b> on AMP-activated protein
kinase (AMPK), which is considered a pharmacological target for treating
metabolic diseases, are described. It was found that an extract of <i>Petasites japonicus</i> produces an increase in the phosphorylation
of AMPK in vitro, and the main active compound <b>1</b> was
isolated. When this compound was administered orally to mice, activation
of AMPK in the liver, skeletal muscle, and adipose tissue was observed.
Moreover, pretreatment with <b>1</b> enhanced glucose tolerance
following the administration of a glucose solution to normal mice.
The mechanism by which <b>1</b> activates AMPK was subsequently
investigated, and an increased intracellular AMP/ATP ratio in the
cultured cells treated with <b>1</b> occurred. In addition,
treatment with petasin inhibited mitochondrial respiratory chain complex
I. Taken together, the present results indicated that <b>1</b> modulates glucose metabolism and activates AMPK through the inhibition
of mitochondrial respiration. The preclinical data suggested that
petasin (<b>1</b>) could be useful for the treatment of metabolic
diseases in humans

Risk of disease flares after SARS-CoV-2 mRNA vaccination in patients with systemic lupus erythematosus
This study aims to elucidate the effectiveness and safety of SARS-CoV-2 mRNA vaccination in patients with systemic lupus erythematosus (SLE). We enrolled uninfected SLE patients who received two vaccine doses (BNT162b2 or mRNA-1273) and historical unvaccinated patients. Neutralizing antibodies, adverse reactions, and disease flares were evaluated 4 weeks after the second vaccination. Ninety patients were enrolled in each group. Among the vaccinated patients, SLE Disease Activity Index (SLEDAI), and prednisolone doses before vaccination were 2, and 5 mg/d, respectively. After the second vaccination, 19 (21.1%) had no neutralizing antibodies. Adverse reactions occurred in 88.9% within 3 d. Negative antibodies were associated with anemia and mycophenolate mofetil administration. SLEDAI increased modestly but significantly after vaccination, with 13 (14.4%) experiencing flares and 4 (4.4%) severe flares (nephritis in three and vasculitis in one). The flare rate was higher in vaccinated patients than unvaccinated controls. The mean duration between the second vaccination and flares was 35 d, and flares occurred at least 8 days after vaccination. Multivariable analysis showed that high SLEDAI and anti-dsDNA antibodies were associated with flares. The vaccine type, neutralizing antibody titer, and adverse reaction frequency did not affect flares. Therefore, residual disease activity before vaccination increases flare risk.</p

Functional annotation of differentially expressed proteins in pSS patient sera. Nodes indicate molecular concepts or set of biologically related genes. Name of each node is indicated in black text on the node. The node size represents the proportion of differentially expressed gene symbols in the concepts (e.g., the “chemokine signaling pathway” and “extracellular region” concepts contain 14 and 58 genes, respectively). Length of lines between nodes represents degree of overlap between symbols. Colored lines indicate strength of functional relationship from strong to weak, as follows: red, yellow, green and gray. Green nodes indicate immune response-related molecular concepts, and red nodes indicate platelet-related molecular concepts. (TIF 9752 kb
