Abstract
Background The region where the ulnar nerve (UN) is swollen in baseball players with ulnar neuropathy is not apparent. This study investigated the UN's cross-sectional area (CSA) at each entrapment point in baseball players. We also aimed to clarify the relationship between valgus instability and the CSA of the UN. Methods Forty baseball players were separated into healthy and ulnar neuropathy groups. The CSA and valgus instability were measured using ultrasonography (US). Relative to the medial epicondyle (MEC), the arcade of Struthers (SA) was 5 cm proximal, the cubital tunnel was the posterior part, and Osborne's ligament was defined as 3 cm distal. The ulnohumeral joint space was imaged as a low-echo space between the distal-medial corner of the trochlea and the proximal edge of the sublime tubercle. Results The UN in the ulnar neuropathy group had significant swelling in the cubital tunnel and Osborne's ligament. We found a weak positive correlation between the CSA and ulnohumeral joint space, and the ulnohumeral joint space at rest and valgus stress. Conclusion Evaluation and treatment of UN, especially cubital tunnel and Osborne's ligament, are necessary for the rehabilitation of baseball players presenting with ulnar neuropathy and valgus instability.

Abstract
[Purpose] We aimed to determine the autonomic response in patients with rotator cuff tear-related nocturnal pain using nonlinear analysis of heart rate variability. [Participants and Methods] Twenty-eight patients with nocturnal pain who were diagnosed with a rotator cuff tear and received steroid injections, and whose nocturnal pain improved, were divided into a control group (14 patients) and a failure group (14 patients). Pulse wave was measured continuously using BACS Advance equipment (TAOS Co.) for a total of 17 min: 5 min before isometric hand grip, 2 min during isometric hand grip, 5 min after isometric hand grip, and 10 min after isometric hand grip. The autonomic nervous system activity was assessed using detrended fluctuation analysis and approximate entropy. [Results] The α1 values obtained from the detrended fluctuation analysis were significantly higher in the failure group than in the control group at each measurement period. The approximate entropy was normal in 12 (85%) patients in the control group and six (42%) patients in the failure group; it was abnormal in two (15%) patients in the control group and eight (58%) patients in the failure group. [Conclusion] Among patients experiencing nocturnal pain, several have abnormal autonomic response during isometric hand grip.

Abstract
[Purpose] We investigated the effects of low-intensity pulsed ultrasound (LIPUS) irradiation of the infrapatellar fat pad (IFP) combined with therapeutic exercise for management of knee osteoarthritis (knee OA). [Participants and Methods] The study included 26 patients with knee OA, who were randomized into the LIPUS group (patients underwent LIPUS + therapeutic exercise) and the therapeutic exercise group (patients underwent sham LIPUS + therapeutic exercise). We measured changes in the patellar tendon-tibial angle (PTTA) and in IFP thickness, IFP gliding, and IFP echo intensity after 10 treatment sessions to determine the effects of the aforementioned interventions. We additionally recorded changes in the visual analog scale, Timed Up and Go Test, the Western Ontario and McMaster Universities Osteoarthritis Index, and Kujala scores, as well as range of motion in each group at the same end-point. [Results] Compared with patients in the therapeutic exercise group, those in the LIPUS group showed significant post-treatment improvements in PTTA, VAS, and Kujala scores, as well as in range of motion. [Conclusion] The combined use of LIPUS irradiation of the IFP and therapeutic exercise is a safe and effective modality to reduce IFP swelling, relieve pain, and improve function in patients with knee OA.

Abstract
Abstract
Introduction
VA ECMO is effective in cardiogenic shock, but complications of cardiogenic pulmonary edema due to increased afterload are problematic. The advent of percutaneous left ventricular assist devices (Impella) has enabled effective reduction of left ventricular intraventricular pressure and has avoided these complications, but differential hypoxia can still occur during VA ECMO + Impella (Ecpella) management, requiring conversion to V-AV ECMO. Cases may be experienced.
Purpose
Elucidate the frequency of differential hypoxia and its pathogenesis, which requires the transition from VA ECMO to V-AV ECMO.
Methods
We retrospectively reviewed 52 consecutive patients who underwent E-CPR from January 2017 through November 2021 in our institute. 8 patients who received ECMO alone were excluded, and 44 patients were recruited. 22 patients underwent VA ECMO with IABP (VA ECMO + IABP group) and 22 patients underwent VA ECMO with Impella (VA ECMO + Impella group). The 30-day survival rate and the rate of transition VA ECMO to VA-V ECMO, The date just before VA ECMO to V-AV ECMO were assessed.
Results
The 30-day all-cause mortality was no significant difference between the two groups. 2 patients (9%) in the VA ECMO + IABP group and 8 patients (36%) in the VA ECMO + Impella group were transferred to V-AV ECMO (P=0.025). At the time of addition of V-AV ECMO, SaO2 (right radial artery) was 87±7.1% and 91.3±1.9% (p=0.112) in the VA ECMO + IABP and VA ECMO + Impella groups, respectively, and the P/F ratio was 86±37.1 and 95±24.6 (p=0.685). Mean pulmonary artery wedge pressure was 23±1.4 mmHg in the VA ECMO + IABP group and 16.3±3 mmHg in the VA ECMO + Impella group (p=0.0193), significantly lower in the Impella group.
Conclusion
The Impella group was more likely to have hypoxia due to factors other than cardiogenic pulmonary edema. In cases of cardiopulmonary arrest requiring V-AV ECMO management, differential hypoxia due to causes other than cardiogenic pulmonary edema may become apparent earlier in the Impella group, suggesting that careful management, including the addition of V-AV ECMO, is required.

Abstract
Abstract
Background
Aortic dissection (AD) is a catastrophic disease that occurs suddenly. The acute mortality is high and those who survived frequently suffer from serious complications such as aneurysm formation and distal ischemia due to progressive destruction of the aortic walls. Currently, no predictor of AD onset is available nor therapeutic intervention to specifically prevent the progressive destruction in AD, because the molecular pathogenesis is largely unknown. Clinical and experimental studies highlighted the importance of inflammation in AD, although the regulatory mechanism of inflammation remains unclear. Recently, we found that cell proliferation precedes the inflammatory response in AD. Because cell proliferation causes cellular senescence that can induce inflammatory response, we hypothesized that cellular senescence participates in AD pathogenesis.
Objective
We investigated if cellular senescence contributes to AD development and progression in mouse AD model.
Methods and results
A mouse AD model was created by continuous infusion of beta-aminopropionitrile and angiotensin II (BAPN+AngII), where AD starts to develop in 3 days and occurs to most of the mice in 14 days accompanied by frequent AD rupture and death. Infusion of BAPN+AngII resulted in the induction of senescence markers Ink4a from day 3 before AD onset and persisted for the 14 days of the observational period.
Cellular senescence, as demonstrated by the expression of senescence-associated beta-galactosidase, was evident in intimal endothelial cells, medial smooth muscle cells, adventitial macrophages and fibroblasts. We examined the role of cellular senescence in AD pathogenesis by oral administration of ABT263 which is known as “senolytics” that eliminates senescent cells. ABT263 treatment reduced the expression of the senescence marker, prevented the death by AD rupture, and ameliorated the severity of AD lesion compared to the vehicle treatment. Transcriptome analysis revealed that ABT treatment suppressed the immune and inflammatory response in AD. Quantitative RT-PCR confirmed that ABT treatment prevented the induction of p21Cip1, interleukin-6, several chemokines and their receptors by 3-day infusion of BAPN+AngII.
Conclusions
These findings demonstrated that senescence of multiple cell types precedes AD development, which is likely to induce the inflammatory response. Elimination of senescent cells effectively prevented AD progression and death. Therefore, cellular senescence represents a potential predictor and a therapeutic target for AD.

Abstract
Abstract
Study question
We investigated the effects of the presence or absence of sERC on subsequent embryonic development and the ploidy of embryos.
Summary answer
The acquisition rates for euploidy embryos were similar to those for the embryos derived from oocytes without smooth endoplasmic reticulum cluster (sERC).
What is known already
The effects of the presence of sERC have been reported on embryonic development processes and pregnancy rate after embryo transfer (ET). In this study, we investigated the effects of the presence of sERC not only on embryonic development and pregnancy rate, but also on the ploidy of embryos from the oocytes with sERC.
Study design, size, duration
The subjects comprised women from whom oocytes were collected from January 2019 to November 2021. The group with the oocytes with sERC was designated as sERC(+), and the other group without sERC as sERC(-).
Participants/materials, setting, methods
Retrospective analysis was performed using a time-lapse system (EmbryoScope+). They were divided into two groups according to the presence of sERC. The groups were compared for fertilization rate, degeneration rate, abnormal fertilization rate (1PN, 3PN, 2.1PN), blastocyst rate, and good-quality-blastocyst rate after ICSI. The prognosis of the transferred embryos was followed up on. In addition, the embryos that were subjected to NGS analysis were investigated for effects of the presence of sERC on their ploidies.
Main results and the role of chance
The sERC(+) group exhibited a significantly lower fertilization rate (74.8%) compared to that of the sERC(-) group (82.4%, P < 0.01). The sERC(+) group exhibited a significantly higher abnormal fertilization rate (14.8%) compared to that of the sERC(-) group (6.6%, P < 0.01). The sERC(+) group showed a significantly higher blastocyst formation rate (57.4%) compared to the sERC(-) group (45.2%, P < 0.01). With respect to after ET prognosis, eight women gave birth with no confirmed congenital anomality. At the very least, the presence of sERC has been shown to have no effect on childbirth. The investigation on ploidy showed that the oocytes in the sERC(+) group included 24.2% euploidy (8/33), 9.1% mosaic (3/33), and 66.7% aneuploidy (22/33) embryos, while the oocytes in the sERC(-) group included 30.4% euploidy (137/451), 12.4% mosaic (56/451), and 57.2% aneuploidy (258/451) embryos. Thus, there was no difference due to the presence of sERC. Three out of the eight euploidy blastocysts in the sERC (+) group had been transferred, one of which reached childbirth.
Limitations, reasons for caution
PGT-A is still under clinical research in Japan.
Wider implications of the findings
Many reports suggested that oocytes with sERC can be used as embryos appropriate for transfer when they develop into blastocysts. The investigation into the ploidy of sERC(+)-derived blastocysts in this study confirmed that the presence of sERC did not affect the ploidy of embryos and that these embryos were transferable.

Abstract
Abstract
Study question
Abnormal cleavage (AC) has been confirmed at early development. We performed an NGS analysis on AC-derived blastocysts to investigate ploidy of the resulting embryos.
Summary answer
Group in which AC occurred during second division showed significantly higher rates for embryos appropriate for transfer than group where AC occurred during first division.
What is known already
Early division is important in embryogenesis and serves as an indicator of subsequent embryonic development. The occurrence of AC during early development can be identified with the advent of the time-lapse incubator, which in turn has led to difficulties in determining whether such AC-derived blastocysts can be used embryo transfer. In this study, we performed NGS analysis on AC-derived blastocysts to investigate the ploidy of the resulting embryos.
Study design, size, duration
The subjects comprised women from whom oocytes were collected for NGS analysis from January 2019 to November 2021. Retrospective analysis was performed using a time-lapse system (EmbryoScope+). Embryos were categorized into two groups: those with abnormal divisions observed during the first and second divisions and those in which normal divisions were observed in the same cycle.
Participants/materials, setting, methods
The group with AC observed was designated the AC group and the other with normal divisions as the Normal Cleavage (NC) group. Within the AC group, the subgroup with AC observed during first division was designated as the First (AC-F) group and the subgroup with AC observed during second division as the Second (AC-S) group for comparing the acquisition rates for euploidy embryos and embryos appropriate for transfer.
Main results and the role of chance
The AC group (17.3%) showed a significantly lower rate of good blastocyst formation than did the NC group (53.4%) (P < 0.01). The cutoff point for mosaicism was defined as > 20% of abnormal cells. Percentage <20 were classified as normal (euploid); >80, abnormal (aneuploidy); and 20-80, mosaic. Using a cutoff of 50% to differentiate ‘‘low’’ mosaics from ‘‘high’’ mosaics. There was no difference between the two groups in the acquisition rates for euploidy embryos (30.8-35.1%) and the embryos appropriate for transfer, including low-mosaic ones (44.3-46.1%). There also was no difference in the acquisition rates for euploidy embryos (24.0-37.0%) between the AC-F and AC-S groups. However, the AC-S group (59.3%) showed significantly higher acquisition rates than the AC-F group (32.0%) for the embryos appropriate for transfer, including low-mosaic ones (P < 0.05).
Limitations, reasons for caution
PGT-A is still under clinical research in Japan.
Wider implications of the findings
The group in which AC occurred during second division showed significantly higher acquisition rates for the embryos appropriate for transfer than the group in which AC occurred during first division. This indicates that the most important factor for identifying euploidy embryos is going through the two-cell phase during first division.

Abstract
[Purpose] The purpose of this study was to examine, using a plethysmogram of the
fingertips, autonomic responses at motor intensities of 30% or 50% of maximum voluntary
contraction (MVC) during isometric handgrip exercise (IHG). [Participants and Methods] The
participants of this study were 15 healthy persons. The finger volume pulse wave of each
participant was measured continuously, using a BACS Advance equipment (TAOS Co.), for a
total of 17 minutes: 5 minutes before IHG (Pre), 2 minutes during IHG (IHG), the first 5
minutes after IHG (Post 5), and then the second 5 minutes after IHG (Post 10). To evaluate
autonomic nervous system activity, we used the Detrended fluctuation analysis (DFA) and
Approximate Entropy (ApEn). [Results] During IHG, the pulse rate was significantly higher
and the ApEn value was significantly lower than during the other periods of measurement.
Compared to other analyzed parameters, ApEn decreased during IHG, but returned to its
initial Pre period level during the Post 5 period. The α1 value derived from
the DFA analysis remained at a value of 1 during each measurement time point, indicating
the absence of malfunctions in autonomic response. [Conclusion] Isometric handgrip
exercise with 30% MVC seemed to be useful for the assessment of autonomic nervous system
response.

Abstract
BACKGROUND In patients with knee osteoarthritis (KOA), the descending genicular artery (DGA) showed abnormal angiogenesis. However, the non-invasive assessment method of DGA remains unclear. The aim of this study was to clarify the characteristics of blood flow velocity of the DGA in patients with KOA and to examine the factors involved in the changes. METHODS The KOA group included 22 knees of 22 patients with KOA (4 males, 18 females; mean age, 72.3 ± 7.5 years) and the control group included 22 knees (4 males, 18 females; mean age, 71.3 ± 5.4 years) of 22 healthy adults. The peak systolic blood flow velocity (PSV) in each group was measured using ultrasonography. The KOA group was classified into the effusion group and the non-effusion group based on observed effusion, and the PSV was compared between the two groups. The relationships between PSV and suprapatellar bursa intracavitary distance, pain, femorotibial angle, Japanese Knee Osteoarthritis Measure were also investigated. RESULTS The PSV in the KOA group (51.5 ± 12.9 cm/s) was significantly higher than that in the control group (29.3 ± 4.4 cm/s) (P < 0.01). In the KOA group, PSV in the effusion group (55.5 cm/s (51.2-59.4 cm/s)) was significantly higher than that in the non-effusion group (39.1 cm/s (35.1-44.4 cm/s)) (P < 0.01). The PSV was positively and significantly correlated with both suprapatellar bursa intracavitary distance (r = 0.81: P < 0.01) and pain (r = 0.48: P < 0.05). CONCLUSIONS The PSV measurement in the DGA is useful for the evaluation of non-invasive synovitis of patients with KOA.

Abstract
[Purpose] This study aimed to clarify the influence of the isometric contraction of the
quadriceps (ICQ) with low intensity on the circulation in the infrapatellar fat pad (IFP).
[Participants and Methods] The participants were 7 males and 5 females, with an average
age of 21.5 ± 1.4 years. IFP hardness was measured using shear wave ultrasound
elastography and Biodex. Tissue oxygenation was measured via near-infrared spectroscopy
using oxygenated hemoglobin (O2Hb), deoxygenated hemoglobin (HHb), and total hemoglobin
(cHb) as indices. The mean values were calculated for three periods: 1 min of rest
immediately before the exercise task (before ICQ), the lower limit of the 10 sets during
the exercise task (during ICQ), and 3–4 min after the exercise task (after ICQ). IFP
hardness was compared between resting conditions and ICQ, and tissue oxygenation was
compared before, during, and after ICQ. [Results] ICQ significantly increased IFP
hardness. Tissue hemoglobin, O2Hb, and cHb decreased significantly during ICQ and
increased after ICQ compared to that before ICQ. HHb decreased during ICQ and recovered
significantly after ICQ. [Conclusion] In healthy participants, low-intensity ICQ increases
the hardness and oxygenation of the IFP. This study may partly explain the unknown pain
relief mechanism of exercise therapy.

Abstract
Abstract
Background
Aortic dissection (AD) is a catastrophic disease that occurs suddenly. The acute mortality is high and those who survived frequently suffer from serious complications such as aneurysm formation and distal ischemia due to progressive destruction of the aortic walls. Currently, no reliable predictor is available for AD development and surgical intervention is the only therapeutic option to prevent the fatal events after AD development, because the pathogenesis of AD is largely unknown.
Clinical and experimental studies highlighted the importance of inflammation in AD pathogenesis, although the trigger of inflammation remains unclear. Recently, we found that cell proliferation precedes the inflammatory response in AD. Because cell proliferation triggers cellular senescence and senescent cells secrete of proinflammatory cytokines and matrix metalloproteinases, we hypothesized that cellular senescence may participate in AD pathogenesis.
Objective
We investigated if cellular senescence contributes to AD development and progression in a mouse model of AD.
Methods and results
A mouse AD model was created by continuous infusion of beta-aminopropionitrile and angiotensin II (BAPN+AngII), where AD starts to develop in 3 days and occurs to most of the mice in 14 days accompanied by frequent AD rupture and death. Infusion of BAPN+AngII resulted in the appearance of senescent cells that are positive for senescence-associated beta-galactosidase, and expression of senescence markers Arf and Ink4a in the aortic walls. Appearance of cellular senescence occurred in one day of BAPN+AngII infusion and continued throughout the observational period of 14 days. We examined the role of cellular senescence in AD pathogenesis by oral administration of ABT263 which is known as “senolytics” that eliminates senescent cells. ABT263 treatment reduced the expression of the senescence markers. In the vehicle-treated group, the mortality was 66.7% (12/18), whereas that of ABT263-treated group was 35% (14/20, P<0.05 by log-rank test). The severity of AD, as assessed by the lesion length in vehicle group was33.2±3.1 mm, whereas that in ABT263 group was 24.6±1.8 mm (P<0.05).
Conclusions
These findings demonstrated that cellular senescence precedes AD development, and ABT263 effectively prevented AD progression and death, indicating the involvement of cellular senescence in AD pathogenesis. Therefore, cellular senescence represents a potential predictor and a therapeutic target for AD.

Abstract
Abstract
Background
Aortic dissection (AD) is a fatal disease where the intimomedial layer of the aorta suddenly fail. Although it is widely accepted that hemodynamic stress on the aortic wall triggers its destruction that is further promoted by inflammatory response as exemplified by the infiltration of neutrophils and macrophages, molecular mechanism is unknown for the link of aortic wall stress, inflammation and tissue destruction. In general, mechanical stress to the tissue is converted to the cellular response through the cell adhesion molecules and the activation of focal adhesion kinase (Fak). Although it has been reported that Fak is involved in pathogenesis of aortic aneurysm by promoting migration and activation of macrophages, its role in AD is unknown. We hypothesized that Fak may be involved in AD pathogenesis.
Purpose
We investigated the involvement of Fak in AD pathogenesis, focusing on its role in inflammatory cells.
Methods and results
We created a mouse model of AD by continuous infusion of beta-aminopropionitrile, a collagen crosslink inhibitor, and angiotensin II (BAPN + Ang II). Immunostaining for activated Fak revealed that Fak was not activated in normal aorta, but was activated in the infiltrating inflammatory cells and in interstitial cells of the aortic wall after AD development. We examined the role of Fak by oral administration of PND-1186, a specific Fak inhibitor, in mouse AD model. Vehicle-treated group showed 63.6% mortality, whereas PND-1186-treated group showed 20% mortality (P<0.01, n=20 for each group) in 14 days of the observational period. The aortic arch lesion, the most critical part in AD, was improved from 1.96±0.41 mm in vehicle group to 0.66±0.29 mm in PND group (P<0.05). We next examined the cell type-specific role of Fak in AD by creating macrophage and granulocyte-specific deletion of Fak driven by LysM-Cre and floxed Fak system. Unexpectedly, the genetic deletion of Fak in macrophages and granulocytes had no impact on the mortality nor the severity of AD.
Conclusions
These findings proved that Fak plays a critical role in AD progression and death. Because Fak is dispensable for macrophages and granulocytes, other cell types, possibly aortic wall interstitial cells, may be regulated by Fak in AD pathogenesis. Deciphering the role of Fak would provide the fundamental understanding of AD pathogenesis.

Abstract
Abstract
Background
Suppressor of cytokine signaling-3 (SOCS3) is a cytokine-inducible negative regulator of signal transducer and activator of transcription-3 (STAT3) signaling pathway. We have previously shown that cardiac-specific SOCS3 deficiency spontaneously develop cardiac dysfunction with advanced age. However, the role of SOCS3 in smooth muscle cells in cardiovascular pathophysiology remains elusive. In this study, we determined whether STAT3 and SOCS3 in smooth muscle cells would play a role in cardiovascular pathophysiology.
Methods and results
To target inactivation of the SOCS3 gene to smooth muscle cells, SOCS3-flox mice were bred with transgenic mice expressing Cre recombinase under control of the mouse SM22-α promoter (sm-SOCS3-KO mice). Left ventricular weight to body weight ratio was significantly increased in sm-SOCS3-KO mice compared with wild-type mice at 12 months of age (p<0.05). Echocardiographic analyses of smSOCS3-KO mice showed significantly increased left ventricular diastolic dysfunction compared with wild-type from 12 months of age (p<0.05). Sirius-red staining revealed that thickness of pericardium and cardiac interstitial fibrosis in sm-SOCS3-KO mice were markedly greater compared with wild-type mice at 12 months of age (p<0.05). Western blot analyses showed that phosphorylated STAT3 was significantly increased in sm-SOCS3-KO hearts compared with wild-type mice at 12 months of age (p<0.05), whereas no significant differences were observed at 2 months of age. To investigate the mechanism that gave rise to promoted cardiac fibrosis and diastolic dysfunction during aging in sm-SOCS3-KO, we conducted a real-time PCR array analysis for fibrosis. The expression of pro-fibrotic CTGF (connective tissue growth factor), PDGFb (platelet growth factor-b), and TGF (transforming growth factor) family genes including TGFb1, TGFb2, and TGFb3, were significantly higher in sm-SOCS3-KO hearts than those in wild-type at 6 months of age.
Conclusion
Thus, smooth muscle cell-specific SOCS3 deletion induces increased pericardial fibrosis, cardiac interstitial fibrosis, and increased diastolic dysfunction in aging mice, possibly through the augmentation of pro-fibrotic growth factors.

Abstract
Abstract
Background
Aortic dissection (AD) is one of the destructive and fatal aortic diseases, for which molecular pathogenesis is largely unknown. Recent studies have highlighted the importance of inflammatory response in AD. We and others reported that B cells and immunoglobulins participate in pathogenesis of abdominal aortic aneurysm, another form of aortic destructive disease, by promoting inflammatory response. It is not known whether and how B cells participate in AD pathogenesis.
Methods and results
Immunohistochemical staining of human AD tissue revealed that B cells were clustered together with T cells, macrophages and neutrophils at the entry site of AD with medial disruption. B cell cluster was also observed at the site of medial disruption in mouse model of AD that was induced by continuous infusion of beta-aminopropionitrile and angiotensin II (BAPN+AngII). In muMT mouse, which is deficient for B cells and immunoglobulins due to genetic deletion of immunoglobulin heavy chain, BAPN+AngII induced significantly less severe AD compared to that in wild type. Depositions of IgG and fibrinogen, one of the endogenous antigen for natural IgG, were observed after BAPN+AngII infusion before and after AD development in wild type mice. Deposition of fibrinogen was also observed in mMT mice after BAPN+AngII infusion. The rate of aortic rupture and sudden death was approximately 42% in wild type mice, while that in muMT mouse was 12% (P<0.05). Administration of mouse normal polyclonal IgG to muMT mice resulted in dramatic increase in aortic rupture and sudden death, starting at day 7 of BAPN+AngII infusion, and reaching 69% of rupture rate, indicating the critical role of IgG in AD.
Conclusion
These findings demonstrated B cells and IgG are critically involved in the destructive inflammation of AD pathogenesis. Further, the deposition of fibrinogen, one of the targets of natural IgG, precedes the development of AD. Our findings may provide the conceptual foundation of the diagnostic strategy for on-going tissue destruction and for the therapeutic opportunities to intervene the progressive tissue destruction in AD.

Abstract
We consider a differentially rotating flow of an incompressible electrically conducting and viscous fluid subject to an external axial magnetic field and to an azimuthal magnetic field that is allowed to be generated by a combination of an axial electric current external to the fluid and electrical currents in the fluid itself. In this setting we derive an extended version of the celebrated Hain-Lüst differential equation for the radial Lagrangian displacement that incorporates the effects of the axial and azimuthal magnetic fields, differential rotation, viscosity, and electrical resistivity. We apply the Wentzel-Kramers-Brillouin method to the extended Hain-Lüst equation and derive a comprehensive dispersion relation for the local stability analysis of the flow to three-dimensional disturbances. We confirm that in the limit of low magnetic Prandtl numbers, in which the ratio of the viscosity to the magnetic diffusivity is vanishing, the rotating flows with radial distributions of the angular velocity beyond the Liu limit, become unstable subject to a wide variety of the azimuthal magnetic fields, and so is the Keplerian flow. In the analysis of the dispersion relation we find evidence of a new long-wavelength instability which is caught also by the numerical solution of the boundary value problem for a magnetized Taylor-Couette flow.

Abstract
Abstract
Background
Aortic dissection (AD) is a fatal disease where the media of the aorta suddenly fail. Currently, Molecular pathogenesis of AD is unknown. Recently, we discovered that the activity of MRTF-A, a mechanosensitive transcriptional regulator, promotes AD development. The activity of MRTF-A is regulated by mechanical stress to cells, which is transduced through focal adhesion and actin dynamics. However, it is currently unknown whether the mechanotransduction mechanism is involved in AD pathogenesis.
Purpose
We investigated the role of focal adhesion kinase (FAK), a signaling molecule that transduces mechanostress from focal adhesion to actin dynamics, in AD pathogenesis.
Methods
We created a mouse model of AD with a continuous infusion of beta-aminopropionitrile (150 mg/kg/day), a collagen crosslink inhibitor, and angiotensin II (1,000 ng/kg/min) (BAPN + AngII) by an osmotic pump. This model caused about 60% death in all mice due to AD rupture within 2 weeks. In this model, we examined the severity and mortality rate of aortic dissection after 2 weeks in mice administered with PND-1186, an orally available FAK inhibitor, and in those treated with vehicle (n=20 for each group). We performed immunochemical staining, immunofluorescence staining and Western blot for activated (phosphorylated) FAK (pFAK) to evaluate the activation status of FAK in the aortic tissue. We also performed transcriptome analysis of the aortic tissue in with and without PND-1186 with BAPN + AngII stimulation before AD development.
Results
Immunochemical staining revealed that FAK was inactive in normal mouse aorta, but was strongly activated in the aortic walls after AD development. Immunofluorescence staining showed that FAK was activated mainly in smooth muscle cells after AD development. Western blot analysis also revealed that FAK was activated in 3 days after BAPN + AngII infusion before AD development, followed by transient reduction at day 7, and re-activation after AD at day 14. Significantly, administration of PND-1186 resulted in a significant reduction in the severity of AD in the aortic arch (1.96±0.41 mm in vehicle group, 0.66±0.29 mm in PND group, P<0.05). In addition, survival rate improved from 36.4% to 80.0% by administration of PND-1186 (P<0.01). In immunofluorescence staining, the PND-1186 treated group showed weaker staining of pFAK. Transcriptome analysis showed that genes for hematopoiesis and immune system were suppressed in PND-1186 treated group.
Conclusions
These findings proved that FAK plays a central role in the pathogenesis of AD probably by transmitting pathological stress to the aortic wall to cause tissue destruction. We propose that FAK is a potential therapeutic target for limiting the fatal destruction of the aortic wall of AD.

Abstract
Abstract
Background
Suppressor of cytokine signaling-3 (SOCS3) is an intrinsic negative-feedback regulator of signal transducer and activator of transcription-3 (STAT3) signaling pathway. We have previously shown that myocardial SOCS3 plays an important role in cardiac hypertrophy and survival; however, the role of SOCS3 in smooth muscle cells in cardiovascular pathophysiology remains elusive. In this study, we determined whether STAT3 and SOCS3 in smooth muscle cells would play a role in cardiovascular pathophysiology.
Methods and results
To target inactivation of the SOCS3 gene to smooth muscle cells, SOCS3-flox mice were bred with transgenic mice expressing Cre recombinase under control of the mouse SM22-α promoter (sm-SOCS3-KO mice). Left ventricular weight to body weight ratio was significantly increased in sm-SOCS3-KO mice compared with wild-type mice at 52 weeks of age (p<0.05). Echocardiographic analyses of sm-SOCS3-KOmice showed significantly decreased cardiac function compared with wild-typefrom 52 weeks of age (p<0.05). Interestingly, Sirius-red staining revealed that thickness of pericardium in sm-SOCS3-KOmice was markedly greater compared with wild-typemice at 52 weeks of age (p<0.05). Cardiac interstitial fibrosis in sm-SOCS3-KOmice was also greater compared with wild-typemice (p<0.05). Western blot analyses showed that phosphorylated STAT3 was significantly increased in sm-SOCS3-KOhearts compared with wild-typemice at 52 weeks of age (p<0.05), whereas no significant differences were observed at 7 weeks of age. Immunostaining revealed that phosphorylated STAT3 positive cells were in thickened pericardial area in sm-SOCS3-KOhearts. Some infiltrated inflammatory cells were also found in thickened pericardial area in sm-SOCS3-KOmice hearts.
Conclusion
These results suggest that STAT3 and its negative-feedback regulator SOCS3 in smooth muscle cells play an important role in the pathogenesis of pericardial fibrosis and cardiac dysfunction.

Abstract
Abstract
Background
Multiple myeloma (MM) is a plasma cell dyscrasia accounting for approximately 13% of hematologic malignancies. Patients with MM have an increased risk of cardiovascular adverse events (CAEs) due to disease burden and/or anti-myeloma treatment-related risk factors. However, little is known about the incidence of cardiovascular toxicity of patients with MM.
Methods
We analyzed 42 consecutive patients (Male/Female 22/20, age 67±10 years old) who received anti-MM therapies between October 2016 and September 2018 from our University Cardio-REnal Oncology (CREO) registry. We examined the incidence of CAEs through January 2019 including congestive heart failure and cardiomyopathy (CHF/CM), ischemic cardiac event, newly symptomatic arrhythmias included atrial fibrillation or flutter requiring treatment, and venous thromboembolism (VTE).
Results
Within the 408-day median follow-up period (range 15–844 days), CAEs occurred in 23.8% (n=10); CHF/CM in 11.9%, newly diagnosed atrial fibrillation in 4.8%, VTE in 4.8%, vasospastic angina in 2.4%, and death in 28.6%. There were no significant differences between CAEs group and non-CAEs group in terms of sex, body mass index (BMI), incidence of hypertension, ischemic heart disease, prior history of heart failure, cardiovascular medications, left ventricular ejection fraction, serum high-sensitivity troponin-I, estimated glomerular filtration rate, blood urea nitrogen and N-terminal pro-brain natriuretic peptide levels at the time of enrollment. The use of various types of proteasome inhibitors and immunomodulatory drugs were not associated with the increased risk of CAEs. By multivariate analysis, a history of prior anti-myeloma therapies was identified as an independent risk factor for CAEs.
Conclusion
CAEs were significantly associated with the recurrent MM in Japanese MM patients.

Abstract
Abstract
Background
Aortic dissection (AD) is a serious clinical condition with unknown etiology that frequently results in fatal outcome. Recent studies showed essential role of inflammatory response both in promoting AD and aortic aneurysm (AA). However, the difference of the molecular pathogenesis between AD and AA is unclear. Previously, we reported that Syk, a tyrosine kinase that regulates differentiation and activation of inflammatory cells, promotes AA formation in a mouse model.
Objective
In the current study, we investigated the role of Syk in AD.
Methods and results
A mouse AD model was created by continuous infusion of beta-aminopropionitrile (125 mg/kg/day) and angiotensin II (1,000 ng/min/kg) (BAPN+AngII), which caused AD in approximately 80% of mice within 14 days. Immunohistochemical staining for activated (phosphorylated) Syk (pSyk) revealed that Syk was inactive in normal mouse aorta, but was activated in the aortic walls after AD development. Double immunofluorescence staining for pSyk and smooth muscle alpha actin showed that Syk was active not only in the infiltrating inflammatory cells, but also in smooth muscle cells in AD tissue. Western blot analysis revealed that BAPN+AngII treatment caused Syk activation at 3 days before AD development, followed by transient suppression, and reactivation at 14 days after AD development. We examined the significance of Syk activation in AD by treating mice with fostamatinib, a specific Syk inhibitor, before and during BAPN+AngII infusion. Notably, fostamatinib-treated group developed more severe AD compared to the vehicle-treated group. The AD lesion length was 3.80±0.86 mm for vehicle group and 8.87±1.69 mm for fostamatinib group (P<0.05, n=12 for each group). In addition, fostamatinib significantly worsened the mortality of mice due to the rupture of the aorta from 0% to 42% (P<0.05, n=12 for each group). Transcriptome analysis revealed that fostamatinib suppressed both positive and negative regulators of immune response, defense response and inflammatory response.
Conclusions
These findings uncovered the previously unrecognized role of Syk for protecting the aortic tissue in AD pathogenesis, and suggested fundamentally different disease mechanisms of AD and AA.

Abstract
Abstract
Background
The prognosis of cancer patients has been improved partly because of the progress in cancer therapy, which increases the cancer survivors in the society. It may raise a concern regarding the development of heart failure (HF), because the anticancer agents have some serious side effects on cardiovascular system, especially in the aging society including Japan. However, the epidemiological data for the risk of HF in the cancer survivors is limited due to the lack of comprehensive dataset in the aging society. In this regard, the electronic health record (EHR), a big data, from the National Health Insurance in Japan provides a unique opportunity to obtain the suitable dataset.
Purpose
The purpose of this study was to clarify the prevalence and the risk factors of HF in cancer survivors, focusing on the impact of their age, using EHR in Japan.
Methods
We examined the EHR of 17.8 million patients, covering 14% of the total Japanese population. The EHR includes the diagnoses as coded with International Classification of Diseases, 10th revision (ICD-10), and the information for therapeutics. We extracted 159,380 patients who received anticancer agents between April 2008 to January 2017. HF patients were identified accordingto ICD-10 codes and the record for the use of therapeutic drugs for HF at least once after the HF diagnosis following the treatment with anticancer agents. We excluded the patients if they had other conditions indistinguishable from HF or if they had past history of HF before receiving anticancer agents.
Results
The mean follow-up period was 1.75 years and mean age (standard deviation) was 68.9 (11.6) years. The population over 75 years old were 37%, while males were 59.5%. There were prostate cancer (28.1%), lung cancer (13.4%), and colon cancer (12.6%)in males, and breast cancer (42.8%), colon cancer (11.5%), and lung cancer (8.6%)in females. Among them, 5,529 patients were diagnosed with HF, corresponding to the prevalence of 3.8%. The mean time form the initiation of chemotherapy to the HF onset was 1.03 year. In the Cox's proportional hazard model after the adjustments for comorbidity, HF was more prevalent in males with hazard ratio (HR) 1.07 and 95% C.I. 1.01–1.13 (p<0.05) and in those with obesity (HR 1.18, 95% C.I. 1.09–1.26, p<0.01).We divided the subjects into three age groups (younger; <65 years, intermediate; 65–74 years, older; ≥75 years). HF was more prevalent in older group than younger group (HR 1.72, 95% C.I. 1.60–1.85, p<0.01). Among the anticancer agents, doxorubicin showed HR 2.09 (95% C.I. 1.89–2.3, p<0.01), and trastuzumab showed HR 1.47 (95% C.I 1.25–1.73, p<0.01).
Conclusion
We showed that the average prevalence of HF after anticancer agentwas 3.8%. The independent risk factors for HF were older age, male, obesity, and the use of doxorubicin or trastuzumab. This study also demonstrated the usefulness of EHR in Japan, to investigate the cardiovascular risk associated with the anticancer agents.

Abstract
Abstract
Background
Interleukin-22 (IL-22) is a member of the IL-10 cytokine family, which mainly targets epithelial cells and does not target immune cells. Recently, it has been reported that IL-22 play roles in tissue repair in the skin and the liver; however, role of IL-22 in the process of tissue repair after myocardial infarction (MI) is unknown. Here, we investigated the role of IL-22 in tissue repair process after MI.
Methods and results
First, we examined the expression of IL-22 and its receptor IL-22RA1 in the wild type (WT) mice by real-time PCR. The expression of IL-22 and IL-22RA1 in the hearts were significantly increased 3 days after MI (p<0.05). To clarify the role of IL-22 in the heart after MI, we produced MI model in the WT mice and IL-22 knockout (KO) mice. We found that the IL-22 KO mice had significantly higher mortality than the WT mice after MI (p<0.05). Approximately 80% of the IL-22 KO mice died with cardiac rupture after MI. The infarct size which was estimated by evans blue dye and triphenyltetrazolium chloride staining at 3 days after MI was comparable between the IL-22 KO mice and the WT mice. Next, we performed real time PCR and PCR array analysis for tissue fibrosis and repair genes. We found that alpha-smooth muscle actin (aSMA), NF-kB, TNF-a and MMP13 (also known as collagenase-3) were significantly increased in the infarct area of IL-22 KO mice compared to WT mice. Immunostaining showed that the myofibroblast marker aSMA positive cells in the border area after MI were markedly higher in the IL-22 KO mice compared with the WT mice (p<0.05). Approximately 70% of cardiac rupture after MI in the IL-22 KO mice were occurred in the infarct area adjacent to the border area. Furthermore, we found aSMA positive cells and MMP13 positive cells around the ruptured site of the heart.
Conclusion
Thus, IL-22 KO mice exhibit high mortality and increased cardiac rupture after MI. And expression of aSMA and MMP13 were highly expressed in the ruptured site after MI in the IL-22 KO mice. These results suggest that IL-22 may play an important role in the tissue repair process after MI.

Abstract
OBJECTIVE Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, with the risk of frailty and poor quality of life. This study aimed to clarify the clinical characteristics of sarcopenia and to investigate the effects of comprehensive cardiac rehabilitation (CCR), including nutrition, physical exercise and medication, in patients with cardiovascular disease (CVD). METHODS We retrospectively studied 322 inpatients with CVD (age 72±12 years). Muscle mass, muscle strength and physical performance were assessed before and after exercise training in patients with and without sarcopenia, which was defined as either a gait speed of <0.8 m/s or reduced handgrip strength (<26 kg in males and <18 kg in females), together with lower skeletal muscle index (SMI) (<7.0 kg/m2 in males and <5.7 kg/m2 in females). The actual daily total calorie and nutrient intake was also calculated. RESULTS Sarcopenia was identified in 28% of patients with CVD, these patients having a higher prevalence of symptomatic chronic heart failure and chronic kidney disease. SMI was significantly associated with protein intake and statin treatment. The ratio of peak VO2 and SMI was significantly higher in the statin treatment group. Handgrip strength, gait speed, leg weight bearing index, and nutritional intake improved after exercise training in patients both with and without sarcopenia. CONCLUSIONS The present findings suggest that CCR is a promising strategy for prevention and treatment of sarcopenia in patients with CVD.

Abstract
BACKGROUND Impaired functional performance and decreased muscle strength and muscle atrophy generally persist for a long period after total hip arthroplasty (THA). AIM To investigate the effects of weight-bearing (WB) and non-weight-bearing (NWB) exercises on functional performance, Harris hip score (HHS), muscle strength and muscle thickness in women after THA. DESIGN A randomised, controlled trial. SETTING Community. POPULATION Sixty-five women who had undergone unilateral or bilateral THA at least 6 months before enrolment in the study. METHODS Participants were randomly allocated to the following groups: WB (n = 22), NWB (n = 21) and control (n = 22) groups. Participants in the WB and NWB groups performed daily home exercise programs for 8 weeks. Functional performance (timed up and go, sit-to-stand, stair climbing, walking speed and 3-min walk test), HHS, isometric muscle strength of the hip and knee muscle and gluteus and quadriceps muscle thickness were measured at baseline and after 8 weeks. RESULTS An intention-to-treat analysis revealed that both the intervention groups exhibited significant improvements in almost all functional performance measures compared with the control group. Furthermore, the WB group showed significantly greater pre-post changes in the sit-to-stand and 3-min walk test compared with the NWB group. In terms of HHS, only the WB group showed significantly greater improvement compared with the control group. Relative to the control group, improvements in all isometric strength measures were observed in both the intervention groups. Significant improvement in quadriceps muscle thickness was observed in the WB group compared with the control group. However, no significant difference was observed among the three groups in pre-post changes in gluteus muscle thickness. CONCLUSION WB and NWB home exercise programs were both effective for improving functional performance and muscle strength in women after THA. However, the WB exercise was more effective than the NWB exercise for improving sit-to-stand ability and walking endurance. CLINICAL REHABILITATION IMPACT In this study, we demonstrated that the WB exercise was more effective than the NWB exercise for improving functional performance in patients after THA.

Abstract
OBJECTIVES The aim of this study was to examine the effect of phosphoenolpyruvate (PEP), a glycolytic intermediate, on organ damage during cold preservation of liver. METHODS An ex-vivo mouse liver cold-preservation model and an in-vitro liver injury model induced by hydrogen peroxide in HepG2 cells were leveraged. KEY FINDINGS PEP attenuated the elevation of aminotransferases and lactate dehydrogenase leakage during organ preservation, histological changes and changes in oxidative stress parameters (measured as thiobarbituric acid reactive substance and glutathione content) induced by 72 h of cold preservation of the liver. The effects were comparable with the University of Wisconsin solution, a gold standard organ preservation agent. The decrease in ATP content in liver during the cold preservation was attenuated by PEP treatment. PEP prevented the cellular injury and increases in intracellular reactive oxygen species in HepG2 cells. In addition, PEP scavenged hydroxyl radicals, but had no effect on superoxide anion as evaluated by an electron paramagnetic resonance spin-trapping technique. CONCLUSIONS PEP significantly attenuated the injury, oxidative stress and ATP depletion in liver during cold preservation. The antioxidative potential of PEP was confirmed by in-vitro examination. We suggest that PEP acts as a glycolytic intermediate and antioxidant, and is particularly useful as an organ preservation agent in clinical transplantation.
