Abstract
ABSTRACT We obtained breath-hold zero TE (ZTE) magnetic resonance imaging for the evaluation of pulmonary arteriovenous malformations before and after embolotherapy. To the best of our knowledge, there have been no reports of ZTE for the entire lung imaging in single breath-hold scan time such as 20 seconds. Breath-hold ZTE magnetic resonance imaging can be a useful technique for magnetic resonance-based follow-up of vascular lung diseases without using contrast media, reducing the undesired artifacts from metallic devices.

Abstract
Zero echo time (ZTE) sequence is recent advanced magnetic resonance technique that utilizes ultrafast readouts to capture signals from short-T2 tissues. This sequence enables T2- and T2* weighted imaging of tissues with short intrinsic relaxation times by using an extremely short TE, and are increasingly used in the musculoskeletal system. We review the imaging physics of these sequences, practical limitations, and image reconstruction, and then discuss the clinical utilities in various disorders of the musculoskeletal system. ZTE can be readily incorporated into the clinical workflow, and is a promising technique to avoid unnecessary radiation exposure, cost, and time-consuming by computed tomography in some cases. LEVEL OF EVIDENCE: 4 TECHNICAL EFFICACY: Stage 1.

Abstract
Carnosic acid (CA) is a phenolic diterpene widely distributed in herbal plants, rosemary and sage. Although its medicinal properties, such as antioxidant, antimicrobial, and neuroprotective effects, have been well-documented, its relevant biochemical processes and molecular targets have not been fully explored yet. In the present study, we conducted an untargeted whole-genome transcriptomics analysis to investigate CA-induced early biological and molecular events in human amniotic epithelial stem cells (hAESCs) with the aim of exploring its multiple tissue-specific functionalities and potential molecular targets. We found that seven days of CA treatment in hAESCs could induce mesoderm-lineage-specific differentiation. Tissue enrichment analysis revealed that CA significantly enriched lateral plate mesoderm-originated cardiovascular and adipose tissues. Further tissue-specific PPI analysis and kinase and transcription factor enrichment analyses identified potential upstream regulators and molecular targets of CA in a tissue-specific manner. Gene ontology enrichment analyses revealed the metabolic, antioxidant, and antifibrotic activities of CA. Altogether, our comprehensive whole-genome transcriptomics analyses offer a thorough understanding of the possible underlying molecular mechanism of CA.

Abstract
BACKGROUND Oxytocin (OXT), a neuropeptide involved in mammal reproductive and prosocial behaviors, has been reported to interact with various stressor-provoked neurobiological changes, including neuroendocrine, neurotransmitter, and inflammatory processes. In view of disturbances in psychosocial relationships due to social isolation and physical distancing measures amid the COVID-19 pandemic, being one of the triggering factors for the recent rise in depression and anxiety, OXT is a potential candidate for a new antidepressant. METHODS In this present study, we have aimed to investigate the effects of oral administration of Rosmarinus officinalis extract (RE), extracted from distillation residue of rosemary essential oil, on central OXT level in the context of other stress biomarkers and neurotransmitter levels in mice models. Tail suspension test (TST) and elevated plus maze test (EPMT) following LPS injection were employed to assess depressive- and anxiety-like behavior in mice, respectively. FINDINGS Pretreatment with RE for seven days significantly improved behavior in TST and EPMT. Whole-genome microarray analysis reveals that RE significantly reversed TST stress-induced alterations in gene expressions related to oxytocinergic and neurotransmitter pathways and inflammatory processes. In both models, RE significantly increased central Oxt and Oxtr expressions, as well as OXT protein levels. RE also significantly attenuated stress-induced changes in serum corticosterone, brain and serum BDNF levels, and brain neurotransmitters levels in both models. INTERPRETATION Altogether, our study is the first to report antidepressant- and anxiolytic-like activities of RE through modulating oxytocinergic system in mice brain and thus highlights the prospects of RE in the treatment of depressive disorders of psychosocial nature.

Abstract
Maslinic acid (MA) is a pentacyclic triterpene abundant in olive peels. MA reportedly increases skeletal muscle mass and strength in older adults; however, the underlying mechanism is unknown. This study aimed to investigate the effects of MA on denervated muscle atrophy and strength and to explore the underlying molecular mechanism. Mice were fed either a control diet or a 0.27% MA diet. One week after intervention, the sciatic nerves of both legs were cut to induce muscle atrophy. Mice were examined 14 days after denervation. MA prevented the denervation-induced reduction in gastrocnemius muscle mass and skeletal muscle strength. Microarray gene expression profiling in gastrocnemius muscle demonstrated several potential mechanisms for muscle maintenance. Gene set enrichment analysis (GSEA) revealed different enriched biological processes, such as myogenesis, PI3/AKT/mTOR signaling, TNFα signaling via NF-κB, and TGF-β signaling in MA-treated mice. In addition, qPCR data showed that MA induced Igf1 expression and suppressed the expressions of Atrogin-1, Murf1 and Tgfb. Altogether, our results suggest the potential of MA as a new therapeutic and preventive dietary ingredient for muscular atrophy and strength.

Abstract
Many living organisms on earth have clock systems in their body. It has increasingly become clear that a disturbance in the internal clocks has negative effects on our body. Terpenes are organic compounds found in various plants that are reported to have several pharmacological actions. In this study, we focused on commercially available 27 triterpenoids and evaluated their influence on the circadian rhythm of human U2OS cells and mouse NIH3T3 cells. The expression level of Per2, one of the core clock genes, was measured using luminescent reporters over the time period of a few days. We found that 8 triterpenoids reset the phase of the circadian clocks. Representative compounds were corosolic acid, cucurbitacin B, and celastrol; similar effects were also confirmed with some structural analogues of cucurbitacin B and celastrol. These compounds shifted the phase bilaterally depending on the stimulus timing and also acted as synchronizers in desynchronized cells. The effective concentrations of cucurbitacin B and celastrol were less than 0.5 μM. In addition, cucurbitacin B and celastrol were also found to be effective in tissue explants in mice. Furthermore, celastrol dose-dependently shortened the period length of NIH3T3 cells. Some of these compounds are found in edible and medicinal plants and may help regulate our circadian clocks in everyday life.

Abstract
Excessive intake of fat is a major risk factor for lifestyle-related diseases such as heart disease and also affects brain function such as object recognition memory, social recognition, anxiety behavior, and depression-like behavior. Although oxytocin (OXT) has been reported to improve object recognition, social recognition, anxiety behavior, and depression-like behavior in specific conditions, previous studies did not explore the impact of OXT in high-fat diet (HFD)-fed mice. Furthermore, it remains unclear whether intake of HFD affects OXT/oxytocin receptor (OXTR) in the brain. Here, we demonstrated that peripheral OXT administration improves not only social recognition but also object recognition and depressive-like behavior in HFD-fed mice. In contrast, peripheral OXT administration to HFD-fed male mice increased fear and anxiety-related behavior. In addition, we observed that intake of HFD decreased OXTR and c-fos mRNA expression in the hippocampus, specifically. Furthermore, peripheral OXT administration increased OXT mRNA expression in the hypothalamus. Altogether, these findings suggest that OXT has the potential to improve various recognition memory processes via peripheral administration but also has side effects that increase fear-related behavior in males.

Abstract
Chronic knee joint pain is common in the elderly and associated with poor quality of life. This study, an open-label clinical trial, aimed to examine how the intake on a daily basis of maslinic acid-containing product (30 mg maslinic acid) on 29 elderly residents (mean 70.7 ± 10.1 years) of Nakajima Island, Ehime, Japan. Study participants consumed 10 g jelly containing maslinic acid daily for 16 weeks and at 0 (baseline), 4, 8, 12 and 16 weeks, assessed for health-related quality of life (Short Form-8) and knee pain score (Japanese Knee Osteoarthritis Measure). After 16 weeks, the physical quality of life, more specifically, the level of Bodily Pain and Physical Component Summary, but not mental quality of life, was significantly improved by maslinic acid intake. Furthermore, maslinic acid intake significantly decreased the Japanese Knee Osteoarthritis Measure at week 8 and tended to decrease Visual Analogue Scale score at weeks 4 and 16. These results suggest that consumption of maslinic acid has a protective effect against chronic knee pain in elderly residents in a community where knee pain causes high quality of life burden.

Abstract
Consumption of olives (Olea europaea L.) is associated with a low incidence of inflammation-related diseases. Olive fruit is rich in bioactive pentacyclic triterpenoids, mainly maslinic acid. This study, a randomized, double-blind, and placebo-controlled trial, examined the effects of an orally administered maslinic acid supplement, olive fruit extract, on 20 middle-aged and elderly volunteers with mild knee joint pain. Each subject (58 ± 7 years) received either olive fruit extract, containing 50 mg maslinic acid (n = 12), or placebo (n = 8) daily for 12 weeks and evaluated for pain and physical functions as primary outcome measures. Secondary outcome measures included body composition and inflammatory biomarkers in serum. Although both groups exhibited improved pain visual analogue scale score and quality of life after supplementation, symptoms were better in the maslinic acid group than in the placebo group. After 12 weeks, maslinic acid group exhibited significant decrease in body weight and body mass index suggesting that maslinic acid affected the weight of volunteers with mild knee joint pain. Therefore, olive products containing maslinic acid may be useful as a new preventive and therapeutic food ingredient for arthritic diseases. Since this clinical study is a preliminary study, it was not registered in a publicly accessible database.

Abstract
SCOPE Consumption of olives (Olea europaea L.), including table olives and oil, is associated with low incidence of inflammation-related diseases. In this study, the effects of maslinic acid (MA), the main constituent of olive pomace, on the expression of genes and proteins involved in inflammatory activity in RAW 264.7 cells were investigated. Furthermore, the effect of MA on carrageenan-induced paw edema and collagen antibody induced arthritis in mice was determined. METHODS AND RESULTS We confirmed the suppressive effects of MA on LPS-induced tumor necrosis factor α production and on the expression of inflammatory response associated genes in RAW 264.7 cells. We also clarified the suppressive effect of MA on LPS-induced nuclear factor-kappa B activation as well as the phosphorylation of IκB-α. Furthermore, MA (200 mg/kg in the edema model or 100 mg/kg in the arthritis model) exerted anti-inflammatory and antiarthritis effects as shown by the suppression of paw edema, arthritis score, inflammatory cells, and destruction of synovium in knee joints. CONCLUSION Olive products containing MA are useful as a new preventive and therapeutic food ingredient for inflammatory and arthritic diseases.

Abstract
α-Linolenic acid (ALA), a major fatty acid in flaxseed oil, has multiple functionalities such as anti-cardiovascular and anti-hypertensive activities. In this study, we investigated the effects of ALA on lipid metabolism and studied the possible mechanisms of its action in differentiated 3T3-L1 adipocytes using DNA microarray analysis. From a total of 34,325 genes in the DNA chip, 87 genes were down-regulated and 185 genes were up-regulated at least twofold in differentiated 3T3-L1 adipocyte cells treated with 300 μM ALA for a week, 5-12 days after induction of cell differentiation, compared to ALA-untreated 3T3-L1 adipocytes (control). From the Reactome analysis results, eight lipid metabolism-related genes involved in cholesterol and triacylglycerol biosynthesis pathway and lipid transport were significantly down-regulated by ALA treatment. Furthermore, ALA significantly decreased the mRNA expressions of sterol regulatory element binding protein (SREBP)-2, SREBP-1a, SREBP-1c and fatty acid synthase (FAS) in 3T3-L1 adipocyte cells. On the other hand, the average levels of the gene expressions of carnitine palmitoyltransferase 1a (CPT-1a) and leptin in 300 μM ALA treatment were increased by 1.7- and 2.9-fold, respectively, followed by an increase in the intracellular ATP content. These results show that ALA is likely to inhibit cholesterol and fatty acid biosynthesis pathway by suppressing the expression of transcriptional factor SREBPs. Furthermore, ALA promotes fatty acid oxidation in 3T3-L1 adipocytes, thereby increasing its health benefits.

Abstract
The effects of flaxseed lignan (secoisolariciresinol diglucoside [SDG]) intake on hypercholesterolemia and liver disease risk factors in moderately hypercholesterolemic men were investigated. In a previous study, we reported that SDG attenuates high-fat, diet-induced hypercholesterolemia in mice. Here, we report a double-blinded, randomized, and placebo-controlled study in moderately hypercholesterolemic men in which we investigated the hypothesis that oral administration of SDG (20 or 100 mg) would decrease the level of blood cholesterol and liver disease risk factors induced by hypercholesterolemia in humans. Thirty men with total cholesterol levels of 4.65 to 6.21 mmol/L (180-240 mg/dL) were randomly assigned to 3 groups; 2 groups received flaxseed lignan capsules (SDG, 20 or 100 mg/d) and the other received placebo capsules for 12 weeks. We found that, compared to the subjects who received placebo, those who received 100 mg of SDG exhibited a significant reduction in the ratio of low-density lipoprotein/high-density lipoprotein cholesterol at baseline (P < .05) and at week 12 (P < .05). In addition, in SDG-treated subjects, we also observed a significant percentage decrease in the levels of glutamic pyruvic transaminase and gamma-glutamyl transpeptidase relative to the levels at baseline (P < .01) and a significant percentage decrease in the level of gamma-glutamyl transpeptidase relative to the placebo-treated group (P < .05). These results suggest that daily administration of 100 mg SDG can be effective at reducing blood level of cholesterol and hepatic diseases risk in moderately hypercholesterolemic men.

Abstract
Background: As there are few available data regarding cancers in Viet Nam, the aim of the present study was to evaluate cancer risk ratios and geographical differences in cancer incidences between the south and north populations in the 1990s. Methods: Data for cancer incidences in Ho Chi Minh (HCM) and Hanoi were derived from published reports. The method for comparison of cancer incidence in two groups used in the present study was the Mantel-Haenszel test. Results: In HCM, all cancers were observed to be lower in males, (RR = 0.87, 95% CI = 0.83-0.91) but higher in females, (RR = 1.06, 95% CI = 1.01-1.12) than in Hanoi. For males, significantly higher incidences in HCM were observed for cancers of the oesophagus (RR = 1.66, 95% CI = 1.19-2.32), liver (RR = 1.22, 95% CI = 1.09-1.36), gall bladder (RR = 5.95, 95% CI = 2.49-14.23), and larynx (RR = 3.54, 95% CI = 2.26-5.55). In contrast, there were much lower incidences in HCM for cancers of the nasopharynx (RR = 0.5, 95% CI = 0.41-0.61), stomach (RR = 0.76, 95% CI = 0.67-0.86), and lung (RR = 0.7, 95% CI = 0.64-0.78). For females, breast cancer incidence was much lower (RR = 0.65, 95% CI = 0.57-0.73) but that of cervical cancer was significantly higher in HCM than in Hanoi, (RR = 3.94, 95% CI = 3.36-4.62), especially for the age group 55-64, (RR = 8.7, 95% CI = 5.9-13.3). Conclusion: The present findings show that cancer risk is quite different in the south and north populations within Viet Nam.

Abstract
It is unclear whether Helicobacter pylori infection is essential to the development of peptic ulcers. In this study, we examined the rates of H. pylori-negativity among patients with peptic ulcers. We also attempted to clarify the characteristics of H. pylori-negative peptic ulcers to throw light on the pathogenesis of peptic ulcers. The study included 215 consecutive patients with gastric ulcers (GUs) and 120 consecutive patients with duodenal ulcers (DUs). After routine endoscopic examination and phenol red dye endoscopy, forceps biopsies were performed for culture, histology, and the rapid urease test. A patient was considered H. pylori-negative when the serum anti-H. pylori IgG and the three tests on biopsied specimens were all negative. H. pylori-negative rates were 3.2% in the patients with GUs and 1.7% in the patients with DUs. Lack of atrophy of the gastric mucosa was significantly more common in the H. pylori-negative patients with GUs. A history of ulcer disease was less common and antral ulcers were more common in H. pylori-negative GU patients, but not significantly so. As the urea breath test had not been performed, the possibility of a false-negative result cannot be completely ruled out, but we believe that the H. pylori-negative rate in our study is more reliable than these rates in previous reports, because we visualized H. pylori distribution by phenol red dye endoscopy to avoid false-negative results in biopsies, and we used both biopsy and serum anti-H. pylori IgG findings to establish an H. pylori-negative diagnosis. Since H. pylori-negative peptic ulcers certainly exist, H. pylori infection is thought not to be essential to the development of peptic ulcers. There were few differences between the characteristics of H. pylori-negative and H. pylori-positive peptic ulcers in our study. A large-scale study is required to clarify the characteristics of H. pylori-negative peptic ulcers.

Abstract
The role of insulin in the pathogenesis of hypertension was explored in normal men and male patients with impaired glucose-tolerance. They were classified as normal (n = 94), borderline (n = 164), impaired tolerance (IGT, n = 104), or diabetes mellitus (n = 100) according to their response to an oral 75g glucose challenge. Besides routine laboratory examinations, fasting immunoreactive insulin and post-glucose insulin levels at 30 minutes were measured. Patients with impaired glucose tolerance were older and more obese than the normal subjects. Serum cholesterol and triglyceride concentrations increased with severity of the glucose tolerance impairment. However, renal function, as estimated by blood urea nitrogen levels did not differ among these four groups. Multiple regression analysis revealed that blood pressure correlates significantly with the obesity index, blood glucose, serum cholesterol and serum insulin in all four groups. Among these groups, the partial F ratios for the obesity index were the greatest in both normal and diabetic groups, but in both borderline and IGT groups those for insulin were the greatest. These results indicate that in patients with impaired glucose tolerance is hypertension associated more closely with hyperinsulinemia than it is in normal subjects or diabetic patients.
