Abstract
OBJECTIVE Skin ageing is inevitably exposed through its typical features such as wrinkles and sagging. Therefore, skin anti-ageing is a major issue in cosmetic research to prevent and improve ageing symptoms using effective ingredients. Chondroitin sulphate (CS), a type of glycosaminoglycan, is an important structural component of the extracellular matrix (ECM) and is involved in various biological processes, such as cell proliferation, differentiation and migration. Here, we aimed to investigate the effects of CS on skin regeneration and examine its efficacy as a potential safe and effective skin anti-ageing ingredient. METHODS We investigated the effects of CS on cell proliferation in normal human keratinocytes and fibroblasts. Then, cell migration, ECM synthesis and related signalling pathways were examined in fibroblasts through gene and protein expression analysis. Finally, the effect on skin wound healing and regeneration was validated using a full-thickness skin wound model and an aged skin model. RESULTS Chondroitin sulphate treatment increased the proliferation of keratinocytes and fibroblasts. It also stimulated the migration and synthesis of ECM components of fibroblasts. Further analysis revealed that CS induced the expression of type I procollagen by activating the extracellular signal-regulated kinase pathway. Using a full-thickness skin wound model and an aged skin model, we confirmed that CS treatment promoted skin wound healing and regeneration. CONCLUSION Together, our results indicated that CS has the potential to facilitate skin regeneration, implying that CS could be clinically applied to improve skin ageing.

Abstract
Transcranial Doppler (TCD) ultrasound is a standard tool used in the setting of recent sub-arachnoid hemorrhage (SAH). By tracking velocity in the circle-of-Willis vessels, vasospasm can be detected as interval velocity increase. For this disease process, repeated TCD velocity measurements over many days is the basis for its usefulness. However, a key limitation to TCD is its user dependence, which is itself largely due to the fact that exact information about probe positioning is lost between subsequent scans. Surface point cloud ultrasound (SPC-US) was recently introduced as a general approach combining ultrasound and three-dimensional surface imaging of patient + probe. In the present proof-of-principle demonstration, we have applied SPC-US to TCD and co-registered the skin surface with that from MRA images to provide a roadmap of the vasculature in 3D space for better speed, accuracy, reproducibility, and potential semi-automation of TCD. Collating the acronyms, we call the combined approach SPC-US-TCD. TCD of the M1 was obtained while three-dimensional photographic images were obtained with the Structure Sensor camera. MRA imaging was also obtained. SPC-US-TCD and corresponding MRA 3D reconstruction images were co-registered in MeshMixer using the skin surfaces for alignment. A cylinder the width of the TCD probe was placed over the fused images and aligned with the direction and orientation of the TCD probe to demonstrate the acoustic beam. In the fused images, the acoustic beam intersects the right M1 segment of the middle cerebral artery (MCA). The angle of insonation is well demonstrated and measurable in various planes. Distance measurements made in Blender localized the TCD probe position based on three skin surface landmarks, and tabulated orientation based on three angles along the corresponding directions. SPC-US-TCD provides valuable information that is otherwise not present in TCD studies. By co-registering SPC-US-TCD data with that from cross sectional vessel imaging, precise probe location relative to external skin surface landmarks as well as 3D vessel location relative to TCD probe placement offers the potential to provide a roadmap that improves exam reproducibility, speed of acquisition, and accuracy. The goal of future work is to demonstrate this improvement statistically by application to multiple patients and scans.

Abstract
BACKGROUND The demanding environment at medical school results in some students being prone to a high risk of mental health issues. GMC recommendations include positioning personal tutors for pastoral support and to act as academic role models. Tutors who are clinicians, such as GPs, could help students develop their academic and professional narratives. Our study explores interactions between GP tutors and students and evaluates how personal tutoring can support the ways in which students respond to the medical school culture and its demands. METHOD Six pairs of GP tutors and medical students had three personal tutor meetings over 9 months. Twelve meetings were recorded. A dialogical narrative analytical approach was used to assess how students' problems and reflective processes were negotiated with tutors. Three themes were formed to consolidate findings. RESULTS Tutors' affirmations helped students develop an alternative narrative to perfectionism focusing on 'doing well' and self-care. Reflection on students' perceptions of a medical career were prompted by tutors who encouraged students to keep an open-minded and enthusiastic outlook. Active participation from students sometimes required tutors to relinquish hierarchical power and share personal experiences. CONCLUSION GP tutors can help reframe student narratives of perfectionism and professionalism by expressing their vulnerabilities and working collaboratively. With clear guidance, there is potential for personal tutors working as GPs, to benefit students in the long run both academically and professionally. However, this should go hand in hand with a transformation of medical school culture to prevent sole focus on building student resilience.

Abstract
More effective treatments for people with psychotic disorders are urgently required. Here, we make three suggestions for progress: 1. Targeting the disorders' core phenomenological features ('phenomenological phenotype'), 2. Addressing social disconnection, isolation and loneliness, and 3. Leveraging 'hot' cognitions and using symptom capture approaches that combine psychotherapy with advances in technology and neuroscience.

Abstract
We report the first measurement of the (e,e^{'}p) three-body breakup reaction cross sections in helium-3 (^{3}He) and tritium (^{3}H) at large momentum transfer [⟨Q^{2}⟩≈1.9 (GeV/c)^{2}] and x_{B}>1 kinematics, where the cross section should be sensitive to quasielastic (QE) scattering from single nucleons. The data cover missing momenta 40≤p_{miss}≤500 MeV/c that, in the QE limit with no rescattering, equals the initial momentum of the probed nucleon. The measured cross sections are compared with state-of-the-art ab initio calculations. Overall good agreement, within ±20%, is observed between data and calculations for the full p_{miss} range for ^{3}H and for 100≤p_{miss}≤350 MeV/c for ^{3}He. Including the effects of rescattering of the outgoing nucleon improves agreement with the data at p_{miss}>250 MeV/c and suggests contributions from charge-exchange (SCX) rescattering. The isoscalar sum of ^{3}He plus ^{3}H, which is largely insensitive to SCX, is described by calculations to within the accuracy of the data over the entire p_{miss} range. This validates current models of the ground state of the three-nucleon system up to very high initial nucleon momenta of 500 MeV/c.

Abstract
Abstract
Introduction
Based on past studies, a child’s temperament and parenting style greatly affect a child’s sleep. However, there are limited studies that have investigated how parenting styles and a child’s temperament interact and affect the child’s sleep in obese children. Thus, this study investigated parenting styles as a moderator in the relationship between temperament and sleep in obese children.
Methods
Seventy-seven obese children (male=66.2%, average BMI = 27.35±2.78) participated in the study. The mean age of the participants was 10.82(± 1.00) years. The primary caregiver (mother) of the participants completed the Junior Temperament and Character Inventory (J-TCI), and Parents as Social Context Questionnaire (K-PSCQ), and Children’s Sleep Habits Questionnaire (CSHQ). Among the different subscales, only Novelty Seeking (NS) and Reward Dependence (RD) were used for analysis among Junior Temperament and Character Inventory (J-TCI) components.
Results
In this sample, 66 children (85.7%) reported significant levels of sleep problems based on the CSHQ. Novelty seeking (NS) and reward dependence (RD) significantly predicted sleep problems (B=-.771, p<.05, B=-.683, p<.01). Additionally, mother’s negative parenting style moderated the relationship between NS and the child’s sleep problem [B=.03, 95% CI=.007, .049] and the relationship between RD and the child’s sleep problem [B=.031, 95% CI=.013, .049]. The more negative mother’s parenting style, the higher the child’s NS or RD scores had a negative effect on sleep.
Conclusion
The results of this study show that obese children experience high levels of sleep disturbance. Additionally, the mother’s negative parenting style moderated the relationship between temperament and sleep problems in obese children. The results suggest that sleep interventions for obese children should include the mother, especially in children with high novelty seeking and reward dependence.

Abstract
Optical amplification by the stimulated emission of Cs(6p2P3/2)-Ar atomic pairs, observed in pump-probe experiments over a ∼290 GHz-wide spectral region lying to the red of the Cs D2 line (852.1 nm), has been realized by photoexciting thermalized, ground state Cs-Ar atoms in the 834-849 nm wavelength interval. When the gain medium is pumped at the peak of the CsAr B2Σ1/2+←X2Σ1/2+ transition at 836.7 nm, maximum gain occurs between 852.2 nm and 852.3 nm and >28% of the energy stored in the upper laser level is extracted with 8 ns (FWHM) probe pulses in a single pass. From the measured rate of saturation of the extracted pulse energy with increasing probe intensity, the product of γ0L and Esat, the saturation pulse energy, is measured directly to be 400 ± 20 µJ and the lower limit for the saturation intensity (Isat) of this amplifier is estimated to be 10 kW-cm-2 at 852.2 nm. Circularly polarizing the optical pump beam increases the optical-to-optical conversion efficiency by 20%, and the storage lifetime of the upper laser level is observed from temporally-resolved gain spectra to be 5 ± 1 ns. Pump excitation spectra also reveal a significant contribution from Ar-Cs-Ar (3-body) photoassociation and suprathermal Ar atoms generated by the dissociation of the CsAr B2Σ1/2+ complex. Multipass-amplifier geometries with broad-bandwidth probe signals are expected to yield upper state energy extraction efficiencies above 50%. This alkali-rare gas amplifier demonstrates the efficiencies available with the storage of energy in, and optical extraction from, excited atomic collision pairs.

Abstract
SETTING: Tuberculosis (TB) and diabetes mellitus (DM) remain global health concerns. Metformin has recently received attention for its anti-tuberculosis effects.OBJECTIVE: To evaluate the risk of TB development in elderly DM patients treated with metformin compared with sulfonylureas.DESIGN: We performed a retrospective cohort study using the National Health Insurance Service-Senior database. The participants were type-2 DM (T2DM) patients aged ≥60 years between 1 January 2003 and 31 December 2013. We matched each metformin user to a sulfonylurea user using a propensity score. A Cox proportional hazards model was used to compare the risk of TB in metformin and sulfonylurea users.RESULTS: After propensity score matching, 12,582 patients were in each group. The TB incidence was 280.2/100 000 person-years (py) for metformin users and 394.5/100 000 py for sulfonylurea users. Metformin users had a lower risk of TB development than sulfonylurea users (adjusted hazard ratio 0.74, 95%CI 0.58-0.95), and the results were stronger for male participants. A dose-response relationship between metformin use and TB development was found in both sexes.CONCLUSION: Metformin use was associated with a decreased risk of TB development among elderly T2DM patients compared with sulfonylurea use.

Abstract
Direct replication of microscale patterns onto metal surfaces by compression molding with patterned dies is used to fabricate metal-based structures for microsystem applications. Micron scale plasticity governs both the mechanical molding response and the geometric fidelity of replicated patterns. Microscale molding replication offers a technologically relevant example in which various plasticity size effects manifest themselves and control the effectiveness of the fabrication process. Microscale compression molding of a single-crystal Al specimen was studied by combining experimentation with conventional and strain gradient plasticity finite element simulations. In the single-punch molding configuration, single rectangular punches with different widths and lengths were used. In the double-punch configuration, two identically-dimensioned rectangular punches with a spacing in between were used. Under single-punch molding at the micron scale, both the absolute punch width as well as the length-to-width ratio affected the characteristic molding pressure. Under double-punch molding, both the measured characteristic molding pressure and the material flow to fill the gap between the two rectangular punches exhibited a significant dependence on the spacing to punch-width ratio and-when this ratio was fixed-on the absolute spacing between punches. The present study elucidates the impact of plasticity size effects on the efficacy of pattern replication by molding at the micron scale.

Abstract
The anisotropic optical dielectric functions of slanted columnar layers fabricated using polymethacrylate based stereolithography are reported for the terahertz-frequency domain using generalized spectroscopic ellipsometry. The slanted columnar layers are composed of spatially coherent columnar structures with a diameter of 100 µm and a length of 700 µm that are tilted by 45° with respect to the surface normal of the substrates. A simple biaxial (orthorhombic) layer homogenization approach is used to analyze the terahertz ellipsometric data obtained at three different sample azimuthal orientations. The permittivity along the major polarizability directions varies by almost 25%. Our results demonstrate that stereolithography allows tailoring of the polarizability and anisotropy of the host material, and provides a flexible alternative metamaterials fabrication method for the terahertz spectral range.

Abstract
OBJECTIVE The objective of this study was to examine whether osteoarthritis (OA) in the knees was associated with total immunoglobulin E (IgE), allergen-specific IgE, or allergic sensitizations in a nationally representative population. METHODS The study population comprised of 785 adults aged 50 years or more in the Korea National Health and Nutrition Examination Survey 2010. OA was diagnosed as radiographic (rOA) and symptomatic osteoarthritis (sxOA). We performed multivariable logistic regression analyses to investigate relationships of OA in a knee with serum total IgE, allergen (Dermatophagoides farinae, cockroach, and dog allergens)-specific IgE, and allergic sensitizations. RESULTS Participants with the highest tertile of the total IgE had 92% and 242% increased risk of knee rOA and sxOA, respectively. Those with D. farinae-specific IgE had 2.2 times increased risk of knee sxOA compared to the lowest tertile. Participants with high total IgE (>150kU/L) had a 60% increased risk of knee rOA. Those with D. farinae-specific sensitization (>0.35kU/L) had 2.0 times increased risk of knee sxOA in compared to those without sensitization. Population-attributable fractions of knee rOA caused by high total IgE and knee sxOA caused by D. farinae-specific sensitization were 9.8% and 15.3%, respectively. CONCLUSIONS Total IgE and D. farinae-specific IgE were significantly associated with OA in knees of Korean adults. High total IgE and D. farinae-specific sensitization were also associated with their OA.

Abstract
This study aimed to develop a chromatographic method to quantitatively determine phenol in fish tissues. This method involves solvent extraction of acidified samples, followed by derivatization to phenyl acetate and analysis with gas chromatography coupled with mass spectrometry (GC–MS). Phenol in a representative tissue sample (belly, gill, or renal tubules), which was homogenized with 2 N sulfuric acid, was extracted with ethyl acetate and derivatized to phenyl acetate using acetic anhydride and K2CO3 in water. An n-butyl acetate extract was injected into the GC–MS. The linearity (r2) of the calibration curve was greater than 0.996. The analytical repeatability, which is expressed as the relative standard deviation, was less than 6.14%, and the recovery was greater than 96.3%. The method detection limit and the limit of quantitation were 8.0 μg/kg and 26 μg/kg, respectively. The proposed method is also applicable to the analysis of other biological tissues for phenol and its analogs, such as pentachlorophenol.

Abstract
In this paper analytical expressions are derived to describe the spin motion of a particle in magnetic and electric fields in the presence of an axion field causing an oscillating electric dipole moment (EDM). These equations are used to estimate statistical sensitivities for axion searches at storage rings. The estimates obtained from the analytic expressions are compared to numerical estimates from simulations in Chang et al. (Phys Rev D 99(8):083002, 2019). A good agreement is found.

Abstract
Background Patient and public involvement (PPI) has become enshrined as an important pillar of health services empirical research, including PPI roles during stages of research development and analysis and co-design approaches. Whilst user participation has been central to qualitative evidence synthesis (QES) for decades, as seen in the Cochrane consumer network and guidelines, meta-ethnography has been slow to incorporate user participation and published examples of this occurring within meta-ethnography are sparse. In this paper, drawing upon our own experience of conducting a meta-ethnography, we focus on what it means in practice to ‘express a synthesis’ (stage 7). We suggest the methodological importance of ‘expression’ in Noblit and Hare’s seven stage process (Noblit, GW and Hare, RD. Meta-ethnography: synthesizing qualitative studies, 1988) has been overlooked, and in particular, opportunities for PPI user participation within it. Methods Meta-ethnography comprises a seven-stage process of evidence synthesis. Noblit and Hare describe the final 7th stage of the meta-ethnography process as ‘expression of synthesis’, emphasizing co-construction of findings with the audience. In a previous study we conducted a meta-ethnography exploring patient and student experience of medical education within primary care contexts. We subsequently presented and discussed initial meta-ethnography findings with PPI (students and patients) in focus groups and interviews. We transcribed patient and student PPI interpretations of synthesis findings. As a research team, we then translated these into our existing meta-ethnography findings. Results We describe, with examples, the process of involving PPI in stage 7 of meta-ethnography and discuss three methodological implications of incorporating PPI within an interpretative approach to QES: (1) we reflect on the construct hierarchy of user participants’ interpretations and consider whether incorporating these additional 1st order, 2nd level constructs implies an additional logic of 3rd order 2nd level constructs of the QES team; (2) we discuss the link between PPI user participation and what Noblit and Hare may have meant by ideas of ‘expression’ and ‘audience’ as integral to stage 7; and (3) we link PPI user participation to Noblit and Hare’s underlying theory of social explanation, i.e. how expression of the synthesis is underpinned by ideas of translation and that the synthesis must be ‘translated in the audience’s (user participants) particular language’. Conclusions The paper aims to complement recent attempts in the literature to refine and improve guidance on conducting a meta-ethnography, highlighting opportunities for PPI user participation in the processes of interpretation, translation and expression. We discuss the implications of user participation in meta-ethnography on ideas of ‘generalisability’.

Abstract
We present the first demonstration of THz driven bunch compression and timing stabilization of a relativistic electron beam. Quasi-single-cycle strong field THz radiation is used in a shorted parallel-plate structure to compress a few-fC beam with 2.5 MeV kinetic energy by a factor of 2.7, producing a 39 fs rms bunch length and a reduction in timing jitter by more than a factor of 2 to 31 fs rms. This THz driven technique offers a significant improvement to beam performance for applications like ultrafast electron diffraction, providing a critical step towards unprecedented timing resolution in ultrafast sciences, and other accelerator applications using femtosecond-scale electron beams.

Abstract
ObjectivesThe objective of the current study was to determine the efficacy of dipping pork trimmings in acetic acid on Salmonella reduction.Materials and MethodsPork loins were purchased from a commercial purveyor and trimmed of external fat and connective tissues, leaving only the longissimus muscle, which was further cut into 2.5 cm (W) × 2.5 cm (L) × 1.3 cm (H) cubes. Pork cubes were randomly assigned to a negative control (no inoculation, no dipping; NEG), a positive control (inoculation, no dipping; POS), acetic acid dipping at 21°C (ACC) and acetic acid dipping at 50°C (ACH) with a 15-, 45-, or 75-s dipping duration (n = 10 per treatment × time combination). Two inoculation levels, 108 Colony Forming Unit (CFU)/cube of bioluminescent gene-modified (Lux) or 105 CFU/cube of nalidixic acid-resistant Salmonella enteritica serovar Typhimurium, were inoculated onto pork cubes to determine the antibacterial effects of each treatment condition by in vivo bioluminescence imaging system (IVIS) or direct CFU measurement on XLD agar, respectively. In Experiment 1, the cubes were dipped for 15 s to measure the reduction effects by employing both IVIS and CFU. In Experiment 2, cubes were dipped with three dipping durations and the CFU were calculated. The common logarithm of Lux and CFU were calculated and analyzed by the GLIMMIX procedure of SAS v9.4 (SAS Institute Inc., Cary, NC). Actual probability values were reported.ResultsIn Experiment 1, at 108 inoculation level, ACC and ACH reduced the growth of Salmonella by 1.8 and 1.6 log, respectively (P < 0.001) without treatment difference (P = 0.207). However, at 105 inoculation level, ACC and ACH reduced Salmonella by 0.2 and 0.3 log, respectively (P ≤ 0.026). In Experiment 2, at 105 inoculation level with three dipping durations, the ACH treatment reduced Salmonella by 0.9 log more than the ACC treatment (P < 0.001). The 75-s dipping duration was the most effective, providing a reduction of 0.7-log more than the 15-s duration (P = 0.001). No 2-way treatment × time interaction was observed (P = 0.104).ConclusionThe present study suggests that the pork trimmings be dipped into 3% acetic acid solution at 50°C for at least 75 s to ensure the safety of further processed pork products.

Abstract
AIM To evaluate the safety and clinical efficacy of interventional treatment for arterial injury during blind, central venous catheterisation in the upper thorax at two tertiary medical centres. MATERIALS AND METHODS Eighteen consecutive patients (37-81 years; M:F=8:10) who underwent interventional treatment for the arterial injuries that occurred during central venous catheterisation without any imaging guidance between November 2007 and December 2018 were included. Clinical data, angiographic findings, detailed interventional procedures, and technical and clinical outcomes were analysed retrospectively. RESULTS Arterial injury sites were the subclavian artery/branches (n=12), axillary artery/branches (n=2), and common carotid artery (n=4). The target vein was not correlated with the corresponding artery/branches in eight patients (44.4%); internal jugular vein to subclavian artery branches. Angiographic findings were pseudoaneurysm (66.7%, 12/18), contrast medium extravasation (22.2%, 4/18), or both (11.1%, n=2). A stent graft was inserted for the main trunk injuries in nine patients, with (n=2) or without (n=7) prior arterial branch embolisation to prevent potential endoleak, while embolisation for the arterial branch injuries was performed in nine patients. Direct percutaneous access with thrombin injection to the pseudoaneurysm or residual arteriovenous fistula was utilised in two. The technical and clinical success rate was 94.4% (17/18) each. There were no procedure-related complications. In one patient without immediate clinical success, there was a persistent pseudoaneurysm after stent graft placement, which was treated with in-stent balloon dilation. CONCLUSION Interventional treatment serves as a safe and effective treatment modality for inadvertent arterial injury related to blind, central venous access catheterisation in the upper thorax.

Abstract
AIM To investigate the diagnostic performance of proton density fat fraction (PDFF) and simultaneous R2* for focal vertebral bone marrow lesion (VBML) assessment, compared with the apparent diffusion coefficient (ADC). MATERIALS AND METHODS One hundred and ninety-two spinal magnetic resonance imaging (MRI) examinations performed in 126 patients with focal VBMLs from March 2016 to November 2018 were reviewed retrospectively. The lesions were divided into metastases and benign VBMLs. The protocol consisted of routine morphological MRI sequences, followed by complex-based chemical shift imaging (CSE)-MRI and diffusion-weighted (DW)-MRI with a 1.5 T system. PDFF, R2*, and the ADC values were compared using the Mann-Whitney U-test. Receiver operating characteristic curve analysis was carried out to assess the diagnostic performance for differentiating metastases from focal benign VBMLs. RESULTS PDFF, R2*, and mean ADC values in metastases were significantly lower than those in benign VBMLs (p<0.05). The PDFF (area under the curve [AUC]= 0.968; 95% confidence interval [CI]=0.932-0.988) showed a significantly larger AUC compared with R2* (AUC=0.670; 95% CI=0.599-0.736) and ADC (AUC=0.801; 95% CI=0.738-0.855). The optimal cut-off value of the PDFF for predicting metastases was 9%; this threshold corresponded to a sensitivity of 96.67%, specificity of 90.28%, and accuracy of 94.27%. CONCLUSION PDFF is significantly more accurate than ADC and R2* for differentiating focal benign VMBLs from metastases.

Abstract
Background
Evidence for the benefit of intensive blood pressure lowering in diabetic nephropathy is not clear at this time. The objective of this study was to demonstrate whether lower mean blood pressure (BP) in treated hypertensive patients with diabetic nephropathy is associated with better prognosis.
Methods
From the National Health Insurance Service (NHIS) Health Examination Database, diabetic hypertensive subjects with proteinuria between 2009 and 2010 were selected and followed-up until 2015 (N=8,663). Mean of the recorded systolic and diastolic BP during follow-up health examinations were stratified into five categories (SBP: <120, 120 to <130, 130 to <140, 140 to <150, and ≥150 mmHg; DBP: <70, 70 to <80, 80 to <90, 90 to <100, and ≥100 mmHg). All-cause death, myocardial infarction (MI), stroke, and renal outcome (progression to end stage renal disease or doubling of serum creatinine) were examined by Cox proportional hazard models with the propensity scores adjusted method.
Results
Compared to SBP of 130 to <140 mmHg, SBP of 120 to <130 mmHg was associated with lower risk of all-cause death (HR=0.78; 95% CI, 0.64–0.95), stroke (HR: 0.65; 95% CI, 0.45–0.94), and renal outcome (HR: 0.81; 95% CI, 0.68–0.97). SBP of <120 mmHg was associated with benefit for renal outcomes (HR: 0.69; 95% CI 0.55–0.88) but not with elevated risk of other outcomes. Compared to DBP of 80 to <90 mmHg, DBP of 70 to <80 mmHg were associated with lower risk of all-cause death (HR: 0.75; 95% CI, 0.64–0.88) but with higher risk of MI (HR: 1.52; 95% CI, 1.05–2.21). DBP of <70 mmHg was associated with reduced risk of all-cause death (HR: 0.79; 95% CI, 0.64–0.98).
Conclusion
In diabetic hypertensive subjects with overt proteinuria, deterioration of renal function decreased with decreasing SBP and the lowest risk of all-cause death and stroke were observed in SBP <130 mmHg. Low DBP was associated with low risk of all-cause death but there was a J curve phenomenon for MI in DBP of 70 to <80 mmHg.

Abstract
Abstract
Introduction
Cardiorespiratory Fitness (CRF), defined as the integrated ability to properly oxygenate skeletal muscles during physical activity, is associated with a high risk of cardiovascular disease and all-cause mortality. The reference range for CRF may differ among nations, with Asians under-represented in previous data.
Purpose
In this study, we sought to establish reference values of CRF for Asians using a recent Korean cohort.
Methods
We analyzed 2646 healthy Korean adults recently enrolled in the Korea Institute of Sports Science Fitness Standards (KISS FitS) project with estimated maximal oxygen uptake (VO2max) values during treadmill test. Patients with cardiovascular or renal disease, systemic infection, pregnant women and those with orthopedic injuries unable to measure physical fitness were excluded. Age-specific mean VO2max values were compared with those from recent American, Norwegian, Danish cohorts and old Korean data.
Results
Age-specific reference values for healthy Korean adults in this cohort were as shown (Table). We were able to draw a nomogram to predict exercise capacity for a given age and MET value (Figure). When compared to other countries, less CRF reduction by aging was seen in Asians than in other Westerners. When compared to old Korean data from the 1980s, values were similar after adjustment for difference in methods, except for those under 30 years old which were decreased.

Conclusions
While there was no significant change in CRF over time in the same ethnic group, there was a clear inter-ethnic difference. CRF should be assessed according to ethnic or national standards, and it is necessary to establish a reference for each nation or ethnicity with periodic updates.

Abstract
Abstract
Introduction
Circulating microparticles (MPs) from patients with coronary artery diseases (CAD) have been shown to promote endothelial senescence and dysfunction involving the pro-oxidant local angiotensin system. Sodium-glucose cotransporters (SGLTs)2 inhibitors decreased the risk of cardiovascular disease in patients with type 2 diabetes and this effect appears to be independent of glycemic control. Moreover, high glucose and H2O2 have been shown to cause a redox-sensitive upregulation of SGLT1 and 2 in coronary artery endothelial cells (ECs).
Aim
Therefore, this study examined whether angiotensin II (Ang II, a potent NADPH oxidase-dependent inducer of oxidative stress) and CAD MPs stimulate SGLT1 and 2 expression in ECs, and assessed their role in the induction of endothelial dysfunction.
Methods
ECs were isolated from porcine coronary arteries. The protein expression level was assessed by Western blot analysis and immunocytochemical staining, oxidative stress using dihydroethidium staining, and senescence by senescence-associated beta-galactosidase activity (SA-beta-gal activity). Circulating CAD MPs were collected from blood samples of patients (61–79 year) with established cardiovascular disease.
Results
Control ECs expressed low levels of SGLT1 and SGLT2 proteins. Exposure of ECs to Ang II caused a time- and concentration-dependent increase in the protein level of SGLT1 and SGLT2 with a significant increase observed at concentrations as low as 10 nM. Exposure of ECs to CAD MPs (10 nM PhtdSer eq) from 3/5 patients increased the SGLT1 and SGLT2 protein level. An increased SGLT1 and SGLT2 immunofluorescence signal was also observed in response to Ang II and H2O2. Ang II increased the level of oxidative stress, SA-beta-gal activity, senescence markers (p53, p21 and p16), VCAM-1, MCP-1, tissue factor (TF) and the local angiotensin system (ACE, AT1R), and down-regulated that of eNOS. CAD MPs from 4/5 patients decreased eNOS level and from 5/5 patients increased VCAM-1 level. All the Ang II-induced effects were prevented by the dual SGLT1/2 inhibitor LX-4211 and the selective SGLT2 inhibitor, empagliflozin.
Conclusions
The present findings indicate that CAD MPs and Ang II upregulate the expression of SGLT1 and SGLT2 protein levels in ECs, and that they promote endothelial dysfunction. They further suggest that inhibition of SGLT1 and/or SGLT2 might be an attractive strategy to protect the arterial wall and, hence, the development of cardiovascular diseases.

Abstract
OBJECTIVE Osteoarthritis (OA) is characterized by cartilage degeneration resulting from hypertrophic changes in chondrocytes caused by altered gene expression. The involvement of Ras homolog enriched in brain (RHEB) in OA regulation is unclear. METHODS Human knee articular cartilage samples - were analyzed for structural and biological changes by histology, immunohistochemistry, real time PCR and western blotting. OA-mouse model developed by surgical destabilization of the medial meniscus (DMM) were treated with adenovirus harboring Rheb gene to analyze onset and progression of OA. Histological scoring, immunohistochemistry, and TUNEL assay was performed to assess cartilage damage across the entire joint. RESULTS Human and mouse OA cartilage is degenerated and has markedly reduced levels of RHEB. Human OA-degenerated chondrocytes (DC) exhibited a fibroblastic phenotype and 80 % of degenerative cartilage were senescent, with higher levels of reactive oxygen species (ROS). Gene expression analysis of DC revealed almost no COL2A1 expression and reduced SOX9 and RHEB expression. Transient transfection of RHEB rescued the DC phenotype and reduced senescence and ROS levels markedly. RHEB overexpression also increased COL2A1 and SOX9 expression. In an OA-mouse model, the Rheb protein level decreased as the severity of OA increased. Ectopic expression of Rheb using adenovirus in mouse-OA cartilage suppressed surgically-induced OA pathogenesis accompanied by modulation of Adamts5, Mmp 13, Col 10, and Col2a1 expression. Rheb induction significantly reduced apoptosis in OA-cartilage. CONCLUSION RHEB plays an important role in maintaining the chondrogenic characteristics of chondrocytes, and has potential in preventing progression of OA in the destabilize the medial meniscus (DMM) mouse model of OA.
