Cardiac function is reduced following myocardial infarction (MI) due to myocardial injury and alterations in the viable non‑ischemic myocardium, a process known as cardiac remodeling. The current treatments available for patients with acute MI (AMI) reduce infarct size, preserve left ventricular (LV) function and improve survival; however, these treatments do not prevent remodeling, which can lead to heart failure. The aim of the present study was to investigate the effects of thyroid hormone (TH) treatment following MI in an in vivo rat model...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

Ischemia-reperfusion (I-R) injury is a serious pathology that is often encountered with thrombotic events, during surgery when blood vessels are cross-clamped, and in organs for transplantation. Increased oxidative stress is the main pathology in I-R injury, as assessed in studies on the heart, kidney, and brain with little data available on gastric I-R (GI-R). Liraglutide is a GLP-1receptor agonist that has insulinotropic and weight reducing actions, and melatonin that has much studied as a chronotropic hormone; have also studied as being antioxidative stress agents...

Metabolic syndrome (MetS) and ovarian hormone deficiency could affect bladder storage dysfunction. Epigallocatechin-3-gallate (EGCG), a polyphenolic compound in green tea, has been shown to protect against ovarian hormone deficiency induced overactive bladder (OAB). The present study investigated oxidative stress induced by MetS and bilateral ovariectomy (OVX), and elucidated the mechanism underlying the protective effect of EGCG (10 umol/kg/day) on bladder overactivity. Rats were fed with high fat high sugar (HFHS) diet to induce MetS and received ovariectomy surgery to deprive ovarian hormone...

Psychological processes may mediate the relationship between minority stress and mental health though limited data exist showing this pathway among trans women. Trans women's degree of satisfaction with their body is associated with mental health outcomes. This study used a model of minority stress to explore for indirect effects on the association between transphobia-based victimization and anxiety and depression through one's degree of body satisfaction. Analysis also explored for racial differences. Transgender women ( N = 233) were recruited in 2013 using respondent-driven sampling...

The adrenal gland regulates stress responses by releasing steroid hormones, whose synthesis and secretion are influenced by adrenal blood flow. Adrenalectomy is commonly performed in rabbits to study the function of the adrenal gland. Although knowledge of the arterial supply to the adrenal gland forms the anatomical basis of the surgery, its description in prior studies is incomplete for the rabbit. Therefore, we observed the adrenal arteries in 27 male and 11 female New Zealand White rabbits using the colored latex injection method...

Treatments for endometriosis include pharmacological or surgical procedures that produce significant side effects. We aimed to determine how environmental enrichment (EE) could impact the progression of endometriosis using the autotransplantation rat model. Female rats were exposed to EE (endo-EE: toys and nesting materials, 4 rats per cage, larger area enclosure) or no enrichment (endo-NE: 2 rats per cage) starting on postnatal day 21. After 8 weeks, sham surgery or surgical endometriosis was induced by suturing uterine horn tissue next to the intestinal mesentery, then allowed to progress for 60 days during which EE or NE continued...

Prostate cancer (PCa) is the third leading cause of death in men in the United States and its treatment options include surgery, anti-hormonal drugs for androgen sensitive tumors, and radiotherapy. An alternative treatment is the use of photodynamic therapy (PDT), which involves the activation of a photosensitizer by a defined wavelength of light in the presence of oxygen, generating transient concentrations of reactive oxygen species (ROS). In this study, we explored the anti-cancer potential and mechanism of action of PDT using pheophorbide (Pheo) as a photosensitizer in combination with 670nm LEDs...
