Amplifying effect of chronic lisinopril therapy on diastolic function and the angiotensin-(1-7) Axis by the G1 agonist in ovariectomized spontaneously hypertensive rats. Transl Res 2021; 235:62-76. [PMID: 33915312 DOI: 10.1016/j.trsl.2021.04.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 04/07/2021] [Accepted: 04/13/2021] [Indexed: 10/21/2022]
Abstract
G protein-coupled estrogen receptor (GPER) activation by G1 attenuates diastolic dysfunction from estrogen loss, which may be partly due to suppression of angiotensin II pathological actions. We aimed to determine the independent effects of 8 weeks of G1 (100 µg/kg/d, subcutaneous pellet), ACE-inhibition (ACEi; lisinopril 10 mg/kg, drinking water), or combination therapy versus vehicle in the ovariectomized (OVX) spontaneously hypertensive rat (SHR) on cardiac function and morphometrics (echocardiography), serum equilibrium of angiotensins (mass spectroscopy) and cardiac components of the RAS (Western blotting). G1 alone and when combined with ACEi enhanced myocardial relaxation (é: 30 and 17%) and diastolic wall strain (DWS: 76 and 68%) while reducing relative wall thickness (RWT: 20 and 33%) and filling pressures (E/é: 30 and 37%). Cardiac expression levels of Mas receptor (Mas-R) and ACE2 also increased in the presence of G1. Strong antihypertensive effects of lisinopril monotherapy were associated with reductions in RWT, collagen deposition and E/é without overtly altering é or DWS. Chronic ACEi also increased cardiac levels of Mas-R and AT1-R and tilted the circulating RAS toward the formation of Ang-(1-7), which was amplified in the presence of G1. In vitro studies further revealed that an inhibitor to prolyl endopeptidase (PEP), but not to neprilysin, significantly reduced serum Ang-(1-7) levels in G1-treated rats, suggesting that G1 might be increasing Ang-(1-7) formation via PEP. We conclude that activating GPER with G1 augments components of the cardiac RAS and improves diastolic function without lowering blood pressure, and that lisinopril-induced blood pressure control and cardiac alterations in OVX SHR are permissive in facilitating G1 to augment Ang-(1-7) in serum, thereby strengthening its cardioprotective benefits.

Physical Exercise Combined with Antihypertensive Drug Therapy on Left Ventricular Hypertrophy: Systematic Review and Meta-Analysis. High Blood Press Cardiovasc Prev 2020; 27:493-503. [PMID: 32776302 DOI: 10.1007/s40292-020-00403-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 07/28/2020] [Indexed: 10/23/2022] Open
Abstract
INTRODUCTION Physical exercise and antihypertensive drugs contribute to reduce or prevent hypertensive heart disease (HHD). The effect on blood pressure (BP) of both combined therapy is well documented, but not for the left ventricular (LV) function. AIM A systematic review and meta-analysis was conducted for LV biomarkers analysis regarding to HHD on subjects treated with antihypertensive drugs combined with physical exercise practice. METHODS The search was conducted on the Pubmed, Bireme, Lilacs, Central (Cochrane) and Science direct databases, comprising undetermined period of time, including randomized studies comparing trained and sedentary subjects, both treated with antihypertensive drugs. We analyzed the influence of combined therapy on echocardiogram parameters and BP. A significance level of 5% and 95% CI was considered for all outcomes. RESULTS Five studies (N = 1738) were included in meta-analysis. Combined therapy decreased significantly LV mass (CI - 21.63 to - 1.81, N = 783) and heart rate (HR; CI - 4.23 to - 1.59, N = 1738), compared to antihypertensive drugs alone. There was a trend to decrease LV mass index (LVMI; CI - 5.57 to 0.71, N = 1674), systolic BP (CI - 2.47 to 1.23, N = 1674) and diastolic BP (CI - 2.16 to 0.28, N = 1674), a trend to increase of ejection fraction (EF; 95% CI - 0.50 to 2.12, N = 783) and LV end-diastolic diameter (CI - 0.85 to 0.92, N = 847) was similar. CONCLUSION The antihypertensive therapy combined with physical exercise practice can reduce LV mass and HR. Therefore, combined therapy prescription should be considered for prevention and treatment of LV hypertrophy of hypertensive subjects.

Avocado (Persea americana) pulp improves cardiovascular and autonomic recovery following submaximal running: a crossover, randomized, double-blind and placebo-controlled trial. Sci Rep 2020; 10:10703. [PMID: 32612186 PMCID: PMC7329896 DOI: 10.1038/s41598-020-67577-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2019] [Accepted: 02/19/2020] [Indexed: 11/28/2022] Open
Abstract
Previous studies have demonstrated that regular avocado consumption presents advantageous effects on cardiovascular system. However, little attention has been paid to the use of avocado as a dietary supplement, in particular, for individuals involved in physical exercise training. Therefore, this study aims to evaluate the effect of acute avocado pulp intake on cardiovascular and autonomic recovery subsequent to moderate exercise. Using a crossover, randomized, double-blind and placebo-controlled trial design, 16 healthy female adults underwent two protocols: Avocado pulp (600 mg in capsule) and placebo (600 mg starch in capsule). After the ingestion of Avocado pulp or placebo, the subjects were seated for 60 min at rest, followed by running on a treadmill at a submaximal level and then remained seated for 60 min during recovery from the exercise. Heart rate (HR), heart rate variability (HRV) [rMSSD, SD1, HF (ms2)] and skin conductance were evaluated before and during exercise, as well as during recovery. HR, systolic blood pressure, HRV and skin conductance recovered faster when subjects were given avocado pulp prior to exercise. In conclusion, avocado pulp improved cardiovascular and autonomic recovery after exercise, suggesting a reduced risk of cardiovascular events after exertion. The current results support the beneficial effects of ingestion of avocado prior to submaximal treadmill running.

Abstract
The focal adhesion kinase-growth factor receptor 2 (FAK-Grb2) protein-protein interaction is implicated in pathogenesis of stress-induced cardiac hypertrophy. The focal adhesion targeting (FAT) domain of FAK unfolds to form a structural intermediate that interacts with a multibinding hot spot in the SH2 domain of Grb2. Disruption of the Grb2-FAT interaction is a therapeutic strategy for prevention of pathological cardiac hypertrophy. A pharmacophore was generated on the basis of structural and electrostatic properties of FAT bound to FAK using the Forge tool (Cresset). This pharmacophore was used as a query for Blaze server (Cresset) to screen a selectively enriched chemical library of 4,32,508 small molecules. The compounds selected were further filtered by hierarchical flexible docking approach using AutoDock v4. From the favorably docked compounds, five were selected on the basis of good adsorption, distribution, metabolism, excretion, and toxicity (ADMET) properties using SwissADME, MedChem Designer v.3, and MOLINSPIRATION. Stability of the binding mode of the inhibitors was further confirmed by molecular dynamic simulation study with AMBER v15 for a simulation time of 50 ns in aqueous environment. PM2307 was identified as the best inhibitor in terms of pharmacophoric features, dock score, and in silico ADMET analysis. The calculated binding affinity of PM2307 was better than that of the FAT-Grb2 complex as well as a previously reported small molecule inhibitor. PM2307 is also a quinolyl derivative sharing a similar scaffold with ofloxacin drugs, asserting its drug-like properties. Thus, it was proposed as a lead compound for development of drugs for pathological cardiac hypertrophy.

Abstract
Stress induced by driving has been revealed to increase the chances of cardiovascular complications and is involved or related to traffic accidents. In order to develop strategies to avoid health problems during driving we aimed to evaluate the acute effects of auditory stimulation with music on heart rate variability (HRV) during driving in congested urban traffic. This is a prospective cross-sectional randomized controlled pilot study conducted with five healthy women. Subjects were evaluated on two different random days, whose order of execution was established through a randomization process. In the music protocol the volunteers were exposed to music for the entire 20 min of traffic while in the control protocol the subjects performed the same procedures but were not exposed to any music. We noted that all Higuchi fractal dimension parameters except Kmax 10, Kmax 130 and Kmax 140 were reduced between pre-driving in the control protocol vs. driving in the control protocol. The same changes were noted between pre-driving in the music protocol vs. driving in the control protocol. In conclusion, musical auditory stimulation improved nonlinear HRV changes induced by driving.

Fisetin inhibits cardiac hypertrophy by suppressing oxidative stress. J Nutr Biochem 2018; 62:221-229.

Abstract
Cardiac hypertrophy is a pathophysiological response to various pathological stresses and ultimately leads to heart failure. Oxidative stress is one of the critical processes involved in hypertrophy development. Fisetin, a small molecular flavonoid, has been shown to have anti-oxidative, anti-proliferative and anti-inflammatory properties. However, the effect of fisetin on cardiac hypertrophy remains unknown. In our present study, we showed that fisetin inhibited pressure overload-induced cardiac hypertrophy, improved cardiac function in vivo and suppressed phenylephrine (PE)-induced cardiomyocyte hypertrophy in vitro. Reactive oxygen species (ROS) levels were markedly decreased by fisetin treatment in both hypertrophic hearts and cardiomyocytes. Moreover, fisetin significantly up-regulated the expression of antioxidative genes, including catalase (CAT), superoxide dismutase 1 (SOD1) and heme oxygenase 1 (HO-1). Furthermore, co-treatment with N-acetylcysteine (NAC; ROS scavenger) and fisetin did not have synergistic inhibitory effects on PE-induced cardiomyocyte hypertrophy, indicating that the anti-hypertrophic effects of fisetin are mainly associated with the blockade of oxidative stress. Finally, the pro-hypertrophic signaling pathways, mitogen-activated protein kinase (MAPK) and mammalian target of rapamycin (mTOR) kinase, were found to be suppressed by fisetin after pressure overload and PE treatment. In conclusion, our study revealed that fisetin protects against cardiac hypertrophy and that oxidative stress inhibition may be one of the pivotal mechanisms involved.

Short-Term Treatment with Esmolol Reverses Left Ventricular Hypertrophy in Adult Spontaneously Hypertensive Rats via Inhibition of Akt/NF- κB and NFATc4. BIOMED RESEARCH INTERNATIONAL 2018; 2018:2691014. [PMID: 29670896 PMCID: PMC5835291 DOI: 10.1155/2018/2691014] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2017] [Revised: 12/24/2017] [Accepted: 01/03/2018] [Indexed: 11/20/2022]
Abstract
Our group has previously demonstrated that short-term treatment with esmolol reduces left ventricular hypertrophy (LVH) in spontaneously hypertensive rats (SHRs). The present study aimed to assess the molecular mechanisms related to this effect. Fourteen-month-old male SHRs were treated intravenously with saline as vehicle (SHR) or esmolol (SHR-E) (300 μg/kg/min). Age-matched vehicle-treated male Wistar-Kyoto (WKY) rats served as controls. After 48 hours of treatment, the hearts were harvested and left ventricular tissue was separated and processed for Western blot analysis to determine the levels of Akt, NF-κB, NFATc4, Creb1, Serca2a, Erk1/2, and Sapk/Jnk. Biomarkers of oxidative stress, such as catalase, protein carbonyls, total thiols, and total antioxidant capacity were evaluated. Esmolol reversed the levels of p-NFATc4, p-Akt, and p-NF-κB in SHRs to the phospholevels of these proteins in WKY rats without modifying p-Erk1/2, p-Sapk/Jnk, p-Creb1, or Serca2a in SHR. Compared with SHR, esmolol increased catalase activity and reduced protein carbonyls without modifying total thiols or total antioxidant capacity. Short-term treatment with esmolol reverses LVH in aged SHRs by downregulation of Akt/NF-κB and NFATc4 activity. Esmolol treatment also increases catalase activity and reduces oxidative stress in SHRs with LVH.

Dronedarone produces early regression of myocardial remodelling in structural heart disease. PLoS One 2017; 12:e0188442.

Abstract
Background and aims Left ventricular hypertrophy (LVH) in hypertension is associated with a greater risk of sustained supraventricular/atrial arrhythmias. Dronedarone is an antiarrhythmic agent that was recently approved for the treatment of atrial fibrillation. However, its effect on early regression of LVH has not been reported. We tested the hypothesis that short-term administration of dronedarone induces early regression of LVH in spontaneously hypertensive rats (SHRs). Methods Ten-month-old male SHRs were randomly assigned to an intervention group (SHR-D), where animals received dronedarone treatment (100 mg/kg) for a period of 14 days, or to a control group (SHR) where rats were given vehicle. A third group with normotensive control rats (WKY) was also added. At the end of the treatment with dronedarone we studied the cardiac anatomy and function in all the rats using transthoracic echocardiogram, cardiac metabolism using the PET/CT study (2-deoxy-2[18F]fluoro-D-glucose) and cardiac structure by histological analysis of myocyte size and collagen content. Results The hypertensive vehicle treated SHR rats developed the classic cardiac pattern of hypertensive cardiomyopathy as expected for the experimental model, with increases in left ventricular wall thickness, a metabolic shift towards an increase in glucose use and increases in myocyte and collagen content. However, the SHR-D rats showed statistically significant lower values in comparison to SHR group for septal wall thickness, posterior wall thickness, ventricular mass, glucose myocardial uptake, size of left ventricular cardiomyocytes and collagen content. All these values obtained in SHR-D rats were similar to the values measured in the normotensive WKY control group. Conclusion The results suggest by three alternative and complementary ways (analysis of anatomy and cardiac function, metabolism and histological structure) that dronedarone has the potential to reverse the LVH induced by arterial hypertension in the SHR model of compensated ventricular hypertrophy.

Abstract
Background There was limited published data on target organ damage (TOD) and the effect of nonadherence to practice guidelines in Ethiopia. This study determined TOD and the long term effect of nonadherence to clinical guidelines on hypertensive patients. Methods An open level retrospective cohort study has been employed at cardiac clinic of Gondar university hospital for a mean follow-up period of 78 months. Multivariate Cox regression was conducted to test associating factors of TOD. Results Of the total number of 612 patients examined, the overall prevalence of hypertensive TOD was 40.3%. The presence of comorbidities, COR = 1.073 [1.01–1.437], AOR = 1.196 [1.174–1.637], and nonadherence to clinical practice guidelines, COR = 1.537 [1.167–2.024], AOR = 1.636 [1.189–2.251], were found to be predicting factors for TOD. According to Kaplan-Meier analysis patients who were initiated on appropriate medication tended to develop TOD very late: Log Rank [11.975 (p = 0.01)]. Conclusion More than forty percent of patients acquired TOD which is more significant. Presence of comorbidities and nonadherence to practice guidelines were correlated with the incidence of TOD. Appropriate management of hypertension and modification of triggering factors are essential to prevent complications.

Abstract
Background: Heart disease as a result of Hypertension is known to occur. Anatomical and functional changes of the heart can easily be detected by echocardiography, which is a safe and readily available study. Objectives: The aims of this study were to evaluate the prevalence of common echocardiographic changes in chronic hypertensive patients and to compare these changes in male and female populations. Design/methods: The study was a community-based cross-sectional study, on 227 hypertensive patients, 60 years and older, seen in St. Joseph's Family Medicine at Clifton, with integrated clinical and echocardiographic data. Results: Study population consisted of 227 hypertensive patients, over the age of 60 years who had echocardiography done. Overall 92.5% of the echocardiograms had abnormal findings including but not limited to TR, Diastolic dysfunction, MR, and LVH. There was significant difference between the rate of MR in male and female population. Conclusion: A variety of echocardiographic abnormalities can be found in hypertensive patients. Drug selection in hypertension should be driven by the underlying cardiac pathology. Certain drugs have more effectiveness for diastolic dysfunction, LVH, systolic dysfunction and pulmonary hypertension and are superior choices when these conditions are present. Echocardiogram is a non-invasive and easily available tool in order to help us to select the best treatment strategy to optimize hypertensive control in the challenging group of elderly patients. The results of our study should influence us to liberally use echocardiography in these patients to guide treatment decision and drug selection. Abbreviations: LVH: left ventricular hypertrophy; MR: mitral valve regurgitation; TR: tricuspidvalve regurgitation; LVD: left ventricular dilation; LVEF: left ventricular ejection fraction.

Abstract
Patients with Fabry disease (FD) are at a high risk for developing chronic kidney disease and cardiovascular disease. The availability of specific but costly therapy has elevated the profile of this rare condition. This KDIGO conference addressed controversial areas in the diagnosis, screening, and management of FD, and included enzyme replacement therapy and nonspecific standard-of-care therapy for the various manifestations of FD. Despite marked advances in patient care and improved overall outlook, there is a need to better understand the pathogenesis of this glycosphingolipidosis and to determine the appropriate age to initiate therapy in all types of patients. The need to develop more effective specific therapies was also emphasized.

Abstract
INTRODUCTION Left Ventricular Hypertrophy (LVH) often reflects as a physiological adaptation to chronic pressure overload. It has been identified as a strong independent risk factor of all-cause mortality and adverse cardiac events. Since not all subjects with hypertension develop LVH, understanding the clinical factors contributing to the development of LVH and the appropriate diagnostic and treatment strategies may help clinicians in conducting more definitive evaluation and managing the disease effectively. AIM To assess the incidence of LVH in hypertensive subjects and the factors influencing its development and reversal. The study also evaluated the most effective diagnostic technique and therapy that could improve the disease symptoms and prognosis. MATERIALS AND METHODS The prospective study, conducted at Jagadguru Sri Shivarathreeshwara (JSS) Medical College JSS University, Mysore, India, included 50 patients with hypertension. Detailed history of the recruited subjects was collected from patient records and through physical examination. Demographic and clinical characteristics such as age, gender, BMI, and stage of hypertension (stage I HTN and stage II HTN) were also obtained. Funduscopic examination was done for all patients for evidence of hypertensive retinopathy. Echocardiography (ECHO), electrocardiography (ECG), and chest X-Ray were used for detection of LVH. The patients were reviewed after six months and reassessment of LVH was carried out. Statistical analysis was conducted using SPSS software and R 3.2 package. RESULTS Angiotensin-Converting Enzyme (ACE) inhibitors were found to be more effective in the treatment of LVH when compared to calcium channel blockers and beta blockers. ECHO was found to be the best method to diagnose LVH. In patients with stage I HTN, 47.1% had normal LVM. Around 53% of the subjects with stage I HTN and all with stage II HTN had abnormal LVM. Retinal changes were noted in 96.2% of abnormal LVM patients and 50% of normal LVM patients. A positive association between BMI and LVH (OR: 1.39) was also noted. CONCLUSION BMI may positively influence LVH regression. The presence of retinopathy, in addition to LVH, suggests an increased chance of regression with anti-hypertensive treatment.

Abstract
Ventricular hypertrophy is a powerful and independent predictor of cardiovascular morbid events. The vascular properties of low-dose acetyl salicylic acid (aspirin) provide cardiovascular benefits through the irreversible inhibition of platelet cyclooxygenase 1; however, the possible anti-hypertrophic properties and potential mechanism of aspirin have not been investigated in detail. In this study, healthy wild-type male mice were randomly divided into three groups and subjected to transverse aortic constriction (TAC) or sham operation. The TAC-operated mice were treated with the human equivalent of low-dose aspirin (10 mg·kg(-1)·d(-1)); the remaining mice received an equal amount of phosphate buffered saline with 0.65% ethanol, which was used as a vehicle. A cardiomyocyte hypertrophy model induced by angiotensin II (10 nmol·L(-1)) was treated with the human equivalent of low (10 or 100 μmol·L(-1)) and high (1000 μmol·L(-1)) aspirin concentrations in plasma. Changes in the cardiac structure and function were assessed through echocardiography and transmission electron microscopy. Gene expression was determined through RT-PCR and western blot analysis. Results indicated that aspirin treatment abrogated the increased thickness of the left ventricular anterior and posterior walls, the swelling of mitochondria, and the increased surface area in in vivo and in vitro hypertrophy models. Aspirin also normalized the upregulated hypertrophic biomarkers, β-myosin heavy chain (β-MHC), atrial natriuretic peptide (ANP), and b-type natriuretic peptide (BNP). Aspirin efficiently reversed the upregulation of β-catenin and P-Akt expression and the TAC- or ANG II-induced downregulation of GSK-3β. Therefore, low-dose aspirin possesses significant anti-hypertrophic properties at clinically relevant concentrations for anti-thrombotic therapy. The downregulation of β-catenin and Akt may be the underlying signaling mechanism of the effects of aspirin.

Abstract
Background There is growing interest in sex differences and RAS components. However, whether gender influences cardiac angiotensin I-converting enzyme (ACE) and angiotensin-converting enzyme 2 (ACE2) activity is still unknown. In the present work, we determined the relationship between ACE and ACE2 activity, left ventricular function and gender in spontaneously hypertensive rats (SHRs). Methodology / Principal Findings Twelve-week-old female (F) and male (M) SHRs were divided into 2 experimental groups (n = 7 in each group): sham (S) and gonadectomized (G). Fifty days after gonadectomy, we measured positive and negative first derivatives (dP/dt maximum left ventricle (LV) and dP/dt minimum LV, respectively), hypertrophy (morphometric analysis) and ACE and ACE2 catalytic activity (fluorimetrically). Expression of calcium handling proteins was measured by western blot. Male rats exhibited higher cardiac ACE and ACE2 activity as well as hypertrophy compared to female rats. Orchiectomy decreased the activity of these enzymes and hypertrophy, while ovariectomy increased hypertrophy and ACE2, but did not change ACE activity. For cardiac function, the male sham group had a lower +dP/dt than the female sham group. After gonadectomy, the +dP/dt increased in males and reduced in females. The male sham group had a lower -dP/dt than the female group. After gonadectomy, the -dP/dt increased in the male and decreased in the female groups when compared to the sham group. No difference was observed among the groups in SERCA2a protein expression. Gonadectomy increased protein expression of PLB (phospholamban) and the PLB to SERCA2a ratio in female rats, but did not change in male rats. Conclusion Ovariectomy leads to increased cardiac hypertrophy, ACE2 activity, PLB expression and PLB to SERCA2a ratio, and worsening of hemodynamic variables, whereas in males the removal of testosterone has the opposite effects on RAS components.

Abstract
Fabry disease is induced by a mutation in the alpha-galactosidase A gene, causing a deficiency of the enzyme alpha-galactosidase A. (1) The enzyme defect leads to progressive intracellular accumulation of globotriaosylceramide in lysosomes of various tissues and organs, including heart, kidney and nerve system. Cardiac involvement is common and is presenting as concentric left ventricular hypertrophy. Myocardial replacement fibrosis is a typical feature of more advanced stages of Fabry cardiomyopathy, first limited to the mid-myocardial layers of the basal postero-lateral wall, then spreading to transmural fibrosis. Since 2001, enzyme replacement therapy is available. If therapy is started early, before myocardial fibrosis has developed, a long-term improvement of myocardial morphology, function and exercise capacity can be achieved. In end-stage cardiomyopathy enzyme replacement therapy might prevent further progression of the disease. This review provides an overview of Fabry disease, with a focus on cardiac involvement with its characteristic features, clinical presentation and possible treatment.

Abstract
Certain β-adrenergic blockers have proven useful in the regression of ventricular remodeling when administered as long-term treatment. However, early regression of left ventricular hypertrophy (LVH) has not been reported, following short-term administration of these drugs. We tested the hypothesis that short-term administration of the cardioselective β-blocker esmolol induces early regression of LVH in spontaneously hypertensive rats (SHR). Fourteen-month-old male SHRs were treated i.v. with vehicle (SHR) or esmolol (SHR-E) (300 μg kg(-1) min(-1)). Age-matched vehicle-treated male Wistar-Kyoto (WKY) rats served as controls. After 48 h, left ventricular morphology and function were assessed using M-mode echocardiograms (left ventricular mass index (LVMI), ejection fraction and transmitral Doppler (early-to-atrial filling velocity ratio (E/A), E-wave deceleration time (Edec time)). The standardized uptake value (SUV) was applied to evaluate FDG (2-deoxy-2[18F]fluoro-D-glucose) uptake by the heart using PET/CT. Left ventricular subendocardial and subepicardial biopsies were taken to analyze changes in cross-sectional area (CSA) of left ventricular cardiomyocytes and the fibrosis was expressed as collagen volume fraction (CVF). LVMI was lower in SHR-E with respect to SHR (P=0.009). There were no significant differences in EF, E/A ratio or Edec time in SHR-E compared with SHR (P=0.17, 0.55 and P=0.80, respectively). PET acquisitions in SHR-E showed lower (18)F-FDG uptake than SHR (P=0.003). Interestingly, there were no significant differences in SUV in either SHR-E or WKY (P=0.63). CSA in subendocardial and subepicardial regions was minor in SHR-E with respect to SHR (P<0.001), and there were no significant differences in CVF between both groups. Esmolol reverses early LVH in the SHR model of stable compensated ventricular hypertrophy. This is the first study to associate early regression of LVH with administration of a short-term β-blocker.

Abstract
BACKGROUND Hydatidiform mole (HM) is characterized by abnormal proliferation of human trophoblast with producers functioning tissues of human chorionic gonadotropin. It can evolve with ovarian cysts tecaluteínicos, hypertension of pregnancy or hyperthyroidism. The incidence of HM is variable and its etiology poorly known, associated with nutritional factors, environmental, age, parity, history of HM, oral contraceptives, smoking, consanguinity or defects in germ cells. There is no reference in literature on HM resulting from sexual violence, objective of this report. METHOD Description of two cases of HM among 1146 patients with pregnancy resulting from sexual violence treated at Hospital Pérola Byington, São Paulo, from July 1994 to August 2011. RESULTS The cases affected young, white, unmarried, low educated and low parity women. Sexual violence was perpetrated by known offenders unrelated to the victims, under death threat. Ultrasound and CT of the pelvis showed bulky uterus compatible with HM without myometrial invasion. One case was associated with theca lutein cysts. The two cases were diagnosed in the second trimester of pregnancy and evolved with hyperthyroidism. There was no hypertension, disease recurrence, metastasis or sexually transmitted infection. CONCLUSION The incidence of HM was 1:573 pregnancies resulting from rape, within the range estimated for Latin American countries. Trophoblastic material can be preserved to identify the violence perpetrator, considering only the paternal HM chromosomes. History of sexual violence should be investigated in cases of HM in the first half of adolescence and women in a vulnerable condition.

Abstract
Background Memantine attenuates heart stress due cold stress, however, no study focused its effects on liver and adrenal gland. We evaluated its effects on lipid depletion in adrenal gland and glycogen depletion in liver of rats exposed to cold stress. Methods Male rats divided into 4 groups: 1)Control (CON); 2)Memantine (MEM); 3)Induced cold stress (IH) and; 4)Induced cold stress memantine (IHF). Memantine were administrated by gavage (20 mg/kg/day) during eight days. Cold stress were performed during 4 hours once at - 8°C. Lipid and glycogen depletion were presented as its intensity levels. Results Rats exposed to cold stress presented the highest glycogen (p < 0.001) and lipid depletion (p < 0.001) in liver and adrenal gland, respectively. We noted that memantine significantly reduced lipid depletion in adrenal gland and glycogen depletion in liver. Conclusion Memantine prevented glycogen depletion in liver and lipid depletion in adrenal gland of rats under a cold stress condition.

Abstract
OBJECTIVE To evaluate the effect of spironolactone on ventricular stiffness in spontaneously hypertensive adult rats subjected to high salt intake. INTRODUCTION High salt intake leads to cardiac hypertrophy, collagen accumulation and diastolic dysfunction. These effects are partially mediated by cardiac activation of the renin-angiotensin-aldosterone system. METHODS Male spontaneously hypertensive rats (SHRs, 32 weeks) received drinking water (SHR), a 1% NaCl solution (SHR-Salt), or a 1% NaCl solution with a daily subcutaneous injection of spironolactone (80 mg.kg⁻¹) (SHRSalt- S). Age-matched normotensive Wistar rats were used as a control. Eight weeks later, the animals were anesthetized and catheterized to evaluate left ventricular and arterial blood pressure. After cardiac arrest, a double-lumen catheter was inserted into the left ventricle through the aorta to obtain in situ left ventricular pressure-volume curves. RESULTS The blood pressures of all the SHR groups were similar to each other but were different from the normotensive controls (Wistar = 109 ± 2; SHR = 118 ± 2; SHR-Salt = 117 ± 2; SHR-Salt-S = 116 ± 2 mmHg; P < 0.05). The cardiac hypertrophy observed in the SHR was enhanced by salt overload and abated by spironolactone (Wistar = 2.90 ± 0.06; SHR = 3.44 ± 0.07; SHR-Salt = 3.68 ± 0.07; SHR-Salt-S = 3.46 ± 0.05 mg/g; P < 0.05). Myocardial relaxation, as evaluated by left ventricular dP/dt, was impaired by salt overload and improved by spironolactone (Wistar = -3698 ± 92; SHR = -3729 ± 125; SHR-Salt = -3342 ± 80; SHR-Salt-S = -3647 ± 104 mmHg/s; P < 0.05). Ventricular stiffness was not altered by salt overload, but spironolactone treatment reduced the ventricular stiffness to levels observed in the normotensive controls (Wistar = 1.40 ± 0.04; SHR = 1.60 ± 0.05; SHR-Salt = 1.67 ± 0.12; SHR-Salt- S = 1.45 ± 0.03 mmHg/ml; P < 0.05). CONCLUSION Spironolactone reduces left ventricular hypertrophy secondary to high salt intake and ventricular stiffness in adult SHRs.
