Abstract
Skeletal muscles in animal models of Duchenne muscular dystrophy (DMD) are more susceptible to contraction-induced functional loss, which is not related to fatigue. Valproic acid (VPA) reportedly improves serological and histological markers of damage in dystrophin-deficient murine muscle. Here, we tested whether VPA would reduce the susceptibility to contraction-induced functional loss in two murine DMD models. Adult female mdx (mild) and D2-mdx (severe) DMD murine models were administered VPA (240 mg/kg) or saline for 7 days. Some VPA-treated mdx mice also performed voluntary running in a wheel, which is known to reduce the susceptibility to contraction-induced functional loss; that is, isometric force drop following eccentric contractions. In situ muscle function was assessed before, during and after eccentric contractions. Muscle utrophin and desmin expression were also evaluated using immunoblotting. Interestingly, VPA reduced the isometric force drop following eccentric contractions in both murine models, without change in the relative eccentric maximal force and in the expression of utrophin and desmin. VPA for 7 days combined with voluntary running had no additive effect compared to VPA alone. Furthermore, VPA reduced the absolute isometric maximal force before eccentric contractions in both murine models. The results of our study indicated that VPA in both murine DMD models reduced the susceptibility to contraction-induced functional loss but increased muscle weakness.

Abstract
BACKGROUND Myocardial infarction (MI) induces a repair response that ultimately generates a stable fibrotic scar. Although the scar prevents cardiac rupture, an excessive profibrotic response impairs optimal recovery by promoting the development of noncontractile fibrotic areas. The mechanisms that lead to cardiac fibrosis are diverse and incompletely characterized. We explored whether the expansion of cardiac fibroblasts after MI can be regulated through a paracrine action of cardiac stromal cells. METHODS We performed a bioinformatic secretome analysis of cardiac stromal PW1+ cells isolated from normal and post-MI mouse hearts to identify novel secreted proteins. Functional assays were used to screen secreted proteins that promote fibroblast proliferation. The expressions of candidates were subsequently analyzed in mouse and human hearts and plasmas. The relationship between levels of circulating protein candidates and adverse post-MI cardiac remodeling was examined in a cohort of 80 patients with a first ST-segment-elevation MI and serial cardiac magnetic resonance imaging evaluations. RESULTS Cardiac stromal PW1+ cells undergo a change in paracrine behavior after MI, and the conditioned media from these cells induced a significant increase in the proliferation of fibroblasts. We identified a total of 12 candidates as secreted proteins overexpressed by cardiac PW1+ cells after MI. Among these factors, GDF3 (growth differentiation factor 3), a member of the TGF-β (transforming growth factor-β) family, was markedly upregulated in the ischemic hearts. Conditioned media specifically enriched with GDF3 induced fibroblast proliferation at a high level by stimulation of activin-receptor-like kinases. In line with the secretory nature of this protein, we next found that GDF3 can be detected in mice and human plasma samples, with a significant increase in the days after MI. In humans, higher GDF3 circulating levels (measured in the plasma at day 4 after MI) were significantly associated with an increased risk of adverse remodeling 6 months after MI (adjusted odds ratio, 1.76 [1.03-3.00]; P=0.037), including lower left ventricular ejection fraction and a higher proportion of akinetic segments. CONCLUSIONS Our findings define a mechanism for the profibrotic action of cardiac stromal cells through secreted cardiokines, such as GDF3, a candidate marker of adverse fibrotic remodeling after MI.

Abstract
For the last 20 years, integrins have been a therapeutic target of interest in the treatment of fibrotic diseases, particularly regarding the integrins of the αV family. Initially developed as anti-cancer drugs but with modest benefits, inhibitors of integrins (such as the anti-αV cilengitide) have shown interesting anti-fibrotic effects in different organs including the heart. Cardiac fibrosis is defined as an accumulation of stiff extracellular matrix in the myocardium, and ultimately leads to heart failure, one of the leading causes of mortality worldwide. Understanding the determinants of cardiac fibrosis and the involvement of integrins is a major matter of public health. This review presents the current knowledge on the different types of cardiac fibrosis and their etiologies, and report on first data supporting specific integrin inhibition therapy as a novel anti-fibrotic strategy, in particular to treat cardiac fibrosis.

Abstract
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8 m class telescopes. The vAPP is a geometric-phase patterned coronagraph that is inherently broadband, and its manufacturing is enabled only by direct-write technology for liquid-crystal patterns. The vAPP generates two coronagraphic point spread functions (PSFs) that cancel starlight on opposite sides of the PSF and have opposite circular polarization states. The efficiency, that is, the amount of light in these PSFs, depends on the retardance offset from a half-wave of the liquid-crystal retarder. Using different liquid-crystal recipes to tune the retardance, different vAPPs operate with high efficiencies (${\gt}96\%$) in the visible and thermal infrared (0.55 µm to 5 µm). Since 2015, seven vAPPs have been installed in a total of six different instruments, including Magellan/MagAO, Magellan/MagAO-X, Subaru/SCExAO, and LBT/LMIRcam. Using two integral field spectrographs installed on the latter two instruments, these vAPPs can provide low-resolution spectra (${\rm{R}} \sim 30$) between 1 µm and 5 µm. We review the design process, development, commissioning, on-sky performance, and first scientific results of all commissioned vAPPs. We report on the lessons learned and conclude with perspectives for future developments and applications.

Abstract
Isolated fallopian tube torsion is a rare but potentially serious event occurring at different times in reproductive life. This diagnosis is often overlooked before surgery. It should be evoked in front acute pelvic pain in patients with history of hydrosalpinx or paratubal cyst. Conservative management must be privileged especially in woman of childbearing age and in a pediatric population.
Introduction and importance Isolated fallopian tube torsion (IFTT) is a rare but potentially serious cause of pelvic pain in women. Despite being a surgical emergency, this diagnosis is often overlooked before surgery. To raise awareness of this diagnosis among clinicians, we describe here five cases, which occurred at different times in reproductive life. Cases presentation We present five cases of isolated fallopian tube torsion at different ages (13–54 years). It often manifests with sudden onset of acute pelvic pain in four cases and chronic pelvic pain in one case. At admission, patients were suspected of adnexal torsion (3 cases), genital infection (1 case), and renal pain (1 case). CT-scan showed IFTT in only one patient. Laparoscopic surgical management, performed by experienced surgeons, consisted of salpingectomy in 4 cases and conservative treatment in one case. The latter was complicated with hydrosalpinx 6 years later. All patients were followed in outpatient clinic at least one time after surgery and had favorable outcomes. Clinical discussion Given the rarity of the pathology and the lack of pathognomonic imaging, IFTT is rarely diagnosed before surgery. Its etiology is still unknown but hydrosalpinx following an infectious process seems to be a major risk factor. Conclusion Increasing awareness of this rare entity is advocated, especially in woman of reproductive age. Torsion should be evoked in front acute pelvic pain in patients with hydrosalpinx or paratubal cyst. Conservative management must be privileged especially in women of childbearing age and in pediatric population.

Abstract
There is currently no therapy to limit the development of cardiac fibrosis and consequent heart failure. We have recently shown that cardiac fibrosis post-myocardial infarction (MI) can be regulated by resident cardiac cells with a fibrogenic signature and identified by the expression of PW1 (Peg3). Here we identify αV-integrin (CD51) as an essential regulator of cardiac PW1+ cells fibrogenic behavior. We used transcriptomic and proteomic approaches to identify specific cell-surface markers for cardiac PW1+ cells and found that αV-integrin (CD51) was expressed in almost all cardiac PW1+ cells (93% ± 1%), predominantly as the αVβ1 complex. αV-integrin is a subunit member of the integrin family of cell adhesion receptors and was found to activate complex of latent transforming growth factor beta (TGFβ at the surface of cardiac PW1+ cells. Pharmacological inhibition of αV-integrin reduced the profibrotic action of cardiac PW1+CD51+ cells and was associated with improved cardiac function and animal survival following MI coupled with a reduced infarct size and fibrotic lesion. These data identify a targetable pathway that regulates cardiac fibrosis in response to an ischemic injury and demonstrate that pharmacological inhibition of αV-integrin could reduce pathological outcomes following cardiac ischemia.

Abstract
KEY POINTS Desmin, similar to dystrophin, is associated with costameric structures bridging sarcomeres to the extracellular matrix. Deletion of the desmin gene in mdx mice [double knockout (DKO) mice] induces marked muscle weakness and fatigue resistance compared to mdx mice. Muscle fragility (higher susceptibility to contraction-induced injury) was also aggravated in DKO mice compared to mdx mice. By contrast to mdx mice, the DKO mice did not undergo muscle hypertrophy. Desmin cDNA transfer with adeno-associated virus in newborn mdx mice reduced muscle weakness. Overall, desmin plays important and beneficial roles in muscle wasting, performance and fragility in dystrophic muscle. ABSTRACT Duchenne muscular dystrophy (DMD) is a severe neuromuscular disease caused by dystrophin deficiency. Desmin, similar to dystrophin, is associated with costameric structures bridging sarcomeres to the extracellular matrix that contributes to muscle function. In the present study, we attempted to provide further insight into the roles of desmin, for which the expression is increased in the muscle from the mouse mdx DMD model. We show that a deletion of the desmin gene (Des) in mdx mice [double knockout (DKO) mice, mdx:desmin-/-] induces a marked muscle weakness; namely, a reduced absolute maximal force production and increased fatigue compared to that in mdx mice. Fragility (i.e. higher susceptibility to contraction-induced injury) was also aggravated in DKO mice compared to mdx mice, despite the promotion of supposedly less fragile muscle fibres in DKO mice, and this worsening of fragility was related to a decreased muscle excitability. Moreover, in contrast to mdx mice, the DKO mice did not undergo muscle hypertrophy, as indicated by smaller and fewer fibres, with a reduced percentage of centronucleated fibres, potentially explaining the severe muscle weakness. Notably, Desmin cDNA transfer with adeno-associated virus in newborn mdx mice improved specific maximal force normalized to muscle weight. Overall, desmin plays important and beneficial roles in muscle wasting, performance and fragility in dystrophic mdx mice, which differ, at least in part, from those observed in healthy muscle.

Abstract
Abstract
Background
Activated cardiac fibroblasts produce extracellular matrix proteins that accumulate during cardiac fibrosis. We have recently shown that PW1 is expressed in a subset of cardiac stromal cells and that cardiac PW1+ cells represent a cellular source of fibroblasts in the ischemic hearts.
Purpose
We aimed to further identify new cell surface markers expressed by cardiac PW1+ cells and to investigate their role in the fibrogenic behavior of these cells.
Methods and results
We first performed transcriptomic and proteomic profiling of FACS-isolated cardiac PW1+ from normal and ischemic hearts. RNA-sequencing output files were processed with bioinformatics algorithms to identify 378 specific cell-surface markers for cardiac PW1+ cells. By comparing these candidates with the proteomic profile, we then cross-identified 9 cell surface proteins primarily involved in cell motility, adhesion to the matrix, inflammatory response and response to wounding. One of these candidates (i.e., aV-integrin or CD51) was expressed in almost all cardiac PW1+ cells (93±1%), and was predominantly found in cells expressing PW1 in the myocardium. Cardiac PW1+ cells showed a predominant expression of aVβ1 complex which is known to mediate fibrosis through TGF-beta activation in a number of tissues. The transfer of isolated cardiac PW1+CD51+ cells into ischemic hearts was associated with fibrosis development. We further demonstrated that inhibition of aV-integrin in cardiac PW1+ cells reduces their profibrotic gene expression profile and their ability to differentiate into fibroblasts. Lastly, a pharmacological blockade of aV-integrin improved cardiac function and animal survival following myocardial infarction coupled with a reduced infarct size and fibrotic lesion.
Conclusions
These data identify a targetable pathway that regulates cardiac fibrosis in response to an ischemic injury and demonstrate that pharmacological inhibition of aV-integrin leads to reduced pathological outcomes following cardiac ischemia.
