The purpose of this study was to investigate the cardiac adrenergic neuronal changes induced by diabetes and hypertension by using an analogue of norepinephrine, meta-iodobenzylguanidine (MIBG), and to compare these changes with the contractile state of ventricular papillary muscle. The tissue concentration of norepinephrine in the cardiac apex was also measured for direct comparison with [123I]MIBG uptake. One week following the induction of diabetes by streptozotocin injection (55 mg/kg, i.v.), male Sprague – Dawley rats were given subcutaneous injections of a hypertension-inducing agent, deoxycorticosterone acetate (DOC A, 25 mg/kg), or DOCA vehicle twice weekly for 3, 6, 9, or 12 weeks. At the end of each time point, the animals were injected intravenously (15 mCi/mg; 1 Ci = 37 GBq) with [123I]MIBG. The results showed a progressive decrease in MIBG uptake into the hearts of diabetic, hypertensive, and diabetic–hypertensive rats during the 12-week observation period, compared with the control group. However, length–tension papillary muscle studies at 12 weeks indicated that only the diabetic group had a diminished performance compared with control. Furthermore, an inverse relationship was observed between MIBG uptake and norepinephrine levels in the cardiac apex of the diabetic and diabetic–hypertensive groups. Therefore, we concluded that either MIBG does not provide an accurate indication of adrenergic integrity or that there is no relationship between sympathetic activity and myocardial function at the time points measured. MIBG did not prove to be a useful marker for myocardial dysfunction in diabetic rats.Key words: diabetes, deoxycorticosterone acetate hypertension, meta-iodobenzylguanidine, adrenergic function, heart.

Abstract Aim To investigate the possible beneficial effect of mirabegron [a selective β3-adrenoceptor (AR) agonist] treatment on erectile dysfunction (ED) in streptozotocin-induced diabetic rats. Methods Sprague-Dawley rats (n=20) were divided into two groups: control group and streptozotocin-induced diabetic group. In vivo erectile responses were evaluated after intracavernosal injection of mirabegron (0.4 mg/kg) in rats. The relaxation responses to electrical field stimulation (EFS, 10 Hz), sodium nitroprusside (SNP, 10 nM) and sildenafil (1 μM) of corpus cavernosum (CC) strips were examined after the incubation with mirabegron (10 μM). β3-ARs expression and localization were determined by Western blot and immunohistochemical analyses in CC tissue. Results In vivo erectile responses of diabetic rats [intracavernasal pressure (ICP) / mean arterial pressure, 0.17±0.01] were decreased, which were restored after administration of mirabegron (0.75±0.01, P<0.001). The basal ICP (7.1±0.6 mmHg) in diabetic rats was markedly increased after mirabegron (36.1 ±5.4 mmHg, P<0.01). Mirabegron caused markedly relaxation in diabetic rat CC after phenylephrine precontraction. The relaxation responses to EFS and sildenafil were reduced in diabetic CC, which were increased in the presence of mirabegron. Mirabegron enhanced SNP-induced relaxation response in both groups. The expression and immunoreactivity of β3-ARs localized to CC smooth muscle were observed in control and diabetic rats. Conclusions This is the first study to show that intracavernosal administration of mirabegron improved erectile function and neurogenic relaxation of CC in diabetic rats. These results may be supported by further studies using combinations of mirabegron and phosphodiesterase type 5 (PDE5) inhibitors for the treatment of diabetic ED, especially in patients who do not respond to PDE5 inhibitor therapy.

Myocyte Contractility

Introduction. High energy defibrillation is recognized to increase postresuscitation myocardial dysfunction. We examined the effects of defibrillation energies on contractility and intracellular Ca 2+ dynamics at the single cardiomyocyte level. Hypothesis. Increasing the defibrillation energy would produce correspondent reduction in myocyte contractility and impairment of intracellular Ca 2+ dynamics. Methods. Ventricular cardiomyocytes, obtained from adult Sprague-Dawley rat hearts, were loaded with Fura-2/AM. The myocytes were then placed in a chamber mounted on an inverted microscope and superfused with a buffer solution at 37 °C. The cells were field stimulated to contract at 0.5 Hz with a field stimulator (IonOptix Corporation, Milton, MA). Mechanical properties were assessed using a video-based edge-detection system (IonOptix Corporation, Milton, MA) and expressed as cell shortening percentage. Intracellular Ca 2+ dynamics were evaluated with a dual-excitation fluorescence photomultiplier system (IonOptix Myocam System) and inferred from the ratio of the fluorescence intensity at the two different wavelengths. Myocytes were randomized into 4 groups of 10 cells each, to receive: a single 0.5 Joule biphasic shock; a single 1 Joule biphasic shock; a single 2 Joule biphasic shock; and a control group without shock. The myocytes were paced for additional 4 min after the shock. Results. A 0.5 Joule shock did not have effects on cardiomyocyte contractility and intracellular Ca 2+ dynamics. Higher energy shock, i.e. 1 or 2 Joule, significantly impaired cardiomyocyte contractility and intracellular Ca 2+ dynamics (p < 0.01). These adverse effects were greater when higher energy was employed (p < 0.01). Table Conclusions. Higher defibrillation energy significantly impairs myocyte contractility. Reductions in cardiomyocyte shortening and intacellular Ca 2+ dynamics abnormalities were greater when higher energy shock was employed. Results

Fermented rice bran (FRB), a prospective supplement, has been proven to ameliorate certain medical conditions. However, its nutraceutical effect on muscle atrophy has never been investigated. The present study aimed to evaluate the effect of FRB on muscle atrophy in a streptozotocin (STZ)-induced diabetic rat model. Three groups of Sprague-Dawley rats, namely the control, STZ, and FRB groups, were treated as follows. The diabetic groups (STZ and FRB) were injected intraperitoneally with STZ (40 mg/kg BW), whereas the control group was injected with the vehicle. The STZ and control groups were fed the AIN93M diet, and the FRB group was fed 10% of FRB based on the AIN93M diet. The diabetic groups had reduced muscle size compared to the control group; however, these changes were alleviated in the FRB group. Moreover, the FRB group had a significantly lower expression of FBXO32/Atrogin-1 and TRIM63/MuRF1 (p < 0.05) due to blocked NF-κB activation. In conclusion, the anti-inflammatory effect of FRB may be beneficial for ameliorating muscle atrophy in diabetic conditions.

Abstract Purpose To investigate the effects of the selective NLRP3 inflammasome inhibitor MCC950 on post-resuscitation myocardial function and survival in a rat model of cardiopulmonary resuscitation (CPR). Methods Thirty-six Sprague Dawley rats were randomized into three groups: (1) MCC950, (2) control, and (3) sham. Each group consisted of a 6 h non-survival subgroup (n = 6) and a 48 h survival subgroup (n = 6). Ventricular fibrillation (VF) was induced and untreated for 6 min. CPR was initiated and continued for 8 min. Resuscitation was attempted with a 4 J defibrillation. MCC950 (10 mg/kg) or vehicle was administered via intraperitoneal injection immediately after the return of spontaneous circulation (ROSC). Myocardial function and sublingual microcirculation were measured after ROSC in the non-survival subgroups. Plasma levels of interleukin Iβ (IL-1β) and cardiac troponin I (cTnI) were measured at baseline and 6 h in the non-survival subgroups. Heart tissue was harvested to measure the NLRP3 inflammasome constituents, including NLRP3, apoptosis-associated speck-like protein (ASC), Caspase-1, and IL-1β. Survival duration and neurologic deficit score (NDS) were recorded and evaluated among survival groups. Results Post-resuscitation myocardial function and sublingual microcirculation were improved in MCC950 compared with control (p < 0.05). IL-1β and cTnI were decreased in MCC950 compared to control (p < 0.01). The MCC950 treated groups showed significantly reduced ASC, caspase-1, and IL-1β compared with the control group (p < 0.05). Survival at 48 h after ROSC was greater in MCC950 (p < 0.05) with improved NDS (p < 0.05). Conclusion Administration of MCC950 following ROSC mitigates post-resuscitation myocardial dysfunction and improves survival.

Introduction: Post-resuscitation myocardial dysfunction has been recognized as one of the major causes of fatal outcomes after initial successful cardiopulmonary resuscitation (CPR). Previous research demonstrated that Netrin-1 improved post ischemic injury cardiac function via preservation of mitochondrial integrity. In the present study, we investigated the role of netrin-1 after cardiac arrest. Hypothesis: We hypothesized that the netrin-1 alleviated post-resuscitation myocardial dysfunction in a rat model of cardiac arrest. Methods: A total of sixteen male Sprague-Dawley rats (450-550 g) were randomized to two groups as follows: (1) Control group (C group); (2) Netrin-1 group (N group). Ventricular fibrillation was induced and untreated for 8 mins followed by 8 mins of CPR. Netrin-1 or saline were given at the onset of precordial compression. Ejection fraction (EF) was measured by echocardiography at baseline, 1,2,3 and 4 hours after ROSC. Results: Eight rats were resuscitated in the netrin-1 group and 7 rats were resuscitated in the saline group. In both groups, EF decreased after resuscitation when compared to the baseline (#p < 0.05). In the netrin-1 group, EF decreased from ( 68.1±3.4)% at baseline to (51.1±5.0)% at 1 hour post-resuscitation. In the saline group, EF decreased from (67.7±2.1)% at baseline to (44.5±5.3)% at 1 hr post-resuscitation. EF was better in the netrin-1 group than in the saline group at 2, 3 and 4 hours post-resuscitation (*p < 0.05) ( Figure 1). Conclusion: Netrin-1 alleviates post-resuscitation myocardial dysfunction in a rat model of cardiac arrest.

Diabetes mellitus has a deleterious effect on the male reproductive system, especially on sperm quality and spermatogenesis. Gynura procumbens (G. procumbens) is a traditional herb known for its ability to improve the fertility of diabetes-induced male rats. This study was designed to identify the differential expression of sperm proteins after treatment with G. procumbens aqueous extract on diabetes-induced male rats. The sperm proteome was profiled using label-free shotgun proteomics analysis. Sprague Dawley rats used in this study were divided randomly into four groups. One group was a normal control group (healthy rats), while the three other groups were induced with 50 mg/kg  bodyweight (BW) of streptozotocin (STZ) to emulate the diabetic condition. The diabetic rats were divided into negative control (non-treated diabetic), metformin-treated (positive control) and G. procumbens aqueous extract-treated (450 mg/kg BW) groups. Oral treatments were administered for 14 consecutive days before the rats were euthanized. Total sperm protein samples were extracted from the caudal epididymis and run through SDS-PAGE. Later, samples were digested using trypsin before liquid chromatography-tandem mass spectrometry (Thermo Orbitrap Fusion) analysis. The acquired data were processed using MaxQuant and Perseus software. The mass spectrometry proteomics data is available through ProteomeXchange Consortium via the PRIDE partner repository, with the dataset identifier PXD011373.
