Cardiotonic drugs and exercise training promote cardiac inotropic effects, which may affect training-induced cardiac adaptations. This study investigated the effects of long-term administration of digoxin on heart structure and function, and physical performance of rats submitted to high-intensity interval training (HIIT). Male Wistar rats, 60 days old, were divided into control (C), digoxin (DIGO), trained (T), and trained with digoxin (TDIGO). Digoxin was administered by gavage (30 µg/kg/day) for 75 days...

Kidney disease represents an important health concern among HIV-infected individuals, with an estimated prevalence ranging between 2.4 and 17%. The widespread use of antiretroviral drugs has changed the epidemiology of kidney disease in the HIV positive population, drastically reducing the percentage of patients affected by HIV-associated nephropathy (HIVAN), a complication characterized by apoptosis and de-differentiation of renal epithelial cells and podocytes. However, impaired kidney function remains an important issue among HIV-infected patients because of their long-term exposure to antiretroviral drugs and the growing burden of traditional risk factors associated with chronic renal disease...

Ketamine, one anesthetic used as an illicit drug, has been detected both in freshwater and marine ecosystems. However, knowledge of its impact on aquatic life is still limited. This study aimed to test its effects in zebrafish embryos by analyzing its time- and dose-dependent developmental toxicity and long-term behavioral changes. The 24h-LC50 was calculated from percent survival using probit analysis. Based on the 24h-LC50 (94.4mgL(-1)), embryos (2hour post-fertilization - hpf) were divided into four groups, including control, and exposed for 24h to ketamine concentrations of 50, 70 or 90mgL(-1)...

BACKGROUND: Potentially inappropriate medication (PIM) is defined as medication with uncertain therapeutic effects and/or potential adverse drug reactions outweighing the clinical benefits. The prescription rate of PIM for oldest-old patients is high despite the existence of lists of PIM (e.g. the PRISCUS list) and efforts to raise awareness. This study aims at identifying general practitioners' views on PIM and aspects affecting the (long-term) use of PIM. METHODS: As part of the CIM-TRIAD study, we conducted semi-structured, qualitative interviews with 47 general practitioners, discussing 25 patients with and 22 without PIM (according to the PRISCUS list)...

Some observational studies raised concern that statins may cause memory impairment, leading to a US Food and Drug Administration warning. Similar questions were raised regarding proprotein convertase subtilisin/kexin-type 9 inhibitors (PCSK9i) and neurocognitive function. No prospectively designed study has evaluated the relationship between long-term PCSK9i use and cognition changes. Patients with prior cardiovascular disease treated with maximally tolerated statin enrolled in FOURIER (the randomized, double-blind, placebo-controlled cardiovascular outcome study of the PCSK9i evolocumab) could participate in this prospective assessment of cognitive function (EBBINGHAUS)...

Polycystic ovary syndrome (PCOS) is a common endocrine disorder, affecting 9-18% of women in reproductive age that causes hyperandrogenism and infertility due to dysfunctional follicular maturation and anovulation. The etiology of PCOS is still poorly known, and information from experimental animal models may help improve current understanding of the mechanisms of PCOS initiation and development. Therefore, we conducted a systematic review of currently available methods for simulation of PCOS in experimental models, focusing on two main endocrine traits: ovarian morphology changes and circulating levels of sex hormones and gonadotropins...

By acting on serotonin 5-HT2A receptors (5-HT2A Rs), serotonergic psychedelic drugs induce perceptual and visual hallucinations by increasing neuronal excitability and altering visual-evoked neuronal responses. The present study was designed to examine whether the perceptual alterations induced by a serotonergic psychedelic drug would affect the integrity of hippocampal-dependent, visually guided spatial cognition. phenylalkylamine hallucinogen TCB-2 is a selective agonist of 5-HT2A Rs. Mice received TCB-2 (1...

Herpes zoster (HZ) is a painful, blistering skin eruption in a dermatomal distribution caused by reactivation of a latent varicella zoster virus in the dorsal root ganglia (DRG). Post-herpetic neuralgia (PHN) is the most common complication of acute herpes zoster (AHZ).Severe prodrome, greater acute pain and dermatomal injury, and the density of the eruption are the risk factors and predictors for developing PHN. PHN has a substantial effect on the quality of life; many patients develop severe physical, occupational, social, and psychosocial disabilities as a result of the unceasing pain...

BACKGROUND: With the development of left ventricular assist device (LVAD), the long-term support has been paid more attention by various researchers. According to previous researches, the combination of LVAD and pharmacological therapy can significantly improve the heart rate recovery and survival rate of patient. However, the effect of pharmacological therapy on the cardiovascular hemodynamic states with LVAD support is still unclear. METHODS: In this study, pharmacokinetic model of captopril is established to describe the relationship between plasma-drug concentration and time...

Mass spectrometry imaging is being increasingly used in metal-based anticancer drug development to study elemental and/or molecular drug distributions in different biological systems. The main analytical tools employed are SIMS (especially nanoSIMS), LA-ICP-MSI and MALDI-MSI as well as a combination of complementary imaging techniques. Main challenges are appropriate sample preparation methods, reliable and validated quantification strategies and a trade-off between sensitivity and spatial resolution. So far, research has mostly focused on the development of analytical methods for imaging with the long term goal to study drug uptake into tumor tissue and toxicity affected organs and to identify cellular targets of metal-based drugs...

Urokinase-type plasminogen activator-severe combined immunodeficiency (uPA/SCID) mice transplanted with human hepatocytes are permissive for hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. However, one of the problems affecting uPA transgenic mice is the expansion of mouse hepatocyte colonies due to homologous recombination of the uPA gene. In this study, we attempted to infect HBV and HCV in humanized cDNA-uPA/SCID mice, a novel uPA transgenic mouse model designed to overcome this disadvantage...

Proton pump inhibitors (PPI) are among the safest class of drugs used by all care providers, including gastroenterologists. They are the mainstay in treatment of acid-related disease, in particular, gastroesophageal reflux disease. Without them, many patients would experience a major decrement in their quality of life. However, no drug is without side effects or adverse events. In the past decade, numerous reports, principally case control studies and meta-analyses, have raised questions about important adverse events related to the use of PPIs...

RATIONALE: Zebrafish have a sophisticated color- and shape-sensitive visual system, so we examined color cue-based novel object recognition in zebrafish. We evaluated preference in the absence or presence of drugs that affect attention and memory retention in rodents: nicotine and the histone deacetylase inhibitor (HDACi) phenylbutyrate (PhB). OBJECTIVES: The objective of this study was to evaluate whether nicotine and PhB affect innate preferences of zebrafish for familiar and novel objects after short- and long-retention intervals...

Painful events early in life have been shown to increase the incidence of interstitial cystitis/painful bladder syndrome in adulthood. However, the intrinsic mechanism is not well studied. We previously reported that neonatal bladder inflammation causes chronic visceral hypersensitivity along with molecular disruption of spinal GABAergic system in rats. The present study investigates whether these molecular changes affect the integrative function and responses of bladder-sensitive primary afferent and spinal neurons...

The current pharmacological approach to Alzheimer's disease (AD) treatment, mostly based on acetylcholinesterase inhibitors (AChEIs), is being revisited, especially in terms of the temporal frames and the potential benefits of their noncanonic actions, raising the question of whether inhibitors of AChE might also act in a disease-modifying manner. Besides, in the last decades, the pharmacophoric moieties of known AChEIs have been covalently linked to other pharmacophores in the pursuit of multitarget hybrid molecules that are expected to induce long-lasting amelioration of impaired neurotransmission and clinical symptoms but also to exert disease-modifying effects...

Mesotherapy, or intradermal therapy, is a therapeutic approach that is gaining popularity, but there is still a significant lack of information on its mechanisms of action or the pharmacokinetics of the therapeutic regimens. This retrospective study on 220 records compared the short-term and long-term effects of mesotherapy using a mixture of drugs versus normal saline solution in the treatment of patients with chronic spinal pain (CSP). At the end of treatment, outcome measures showed a significant improvement (P<0...
