BACKGROUND: Social crowding and isolation are recognized as major stressors and risk factors for development of psychiatric disorders. Chronic isolation stress (IS) and crowding stress (CS) activate neuroendocrine and neurochemical mechanisms, that activate the hypothalamic-pituitary-adrenal (HPA) axis. Changes of the plasma level of interleukin-1β (IL-1β), ACTH and corticosterone (CORT) after chronic psychosocial IS and CS were investigated. METHODS: Control rats were kept 5 per cage and not stressed...

Diabetes mellitus is associated with abnormal bone health and an increased risk of fracture even though patients have normal or higher BMD. The mechanisms behind diabetes mellitus- induced various skeletal disorders remain unclear. Anti-diabetic drugs may have negative or positive impact on bone metabolism. For instance, thiazolidinediones increases the bone loss and risk of fracture possibly through PPARγ activation in bone marrow cells and hamper osteoblastogenesis via decreasing Runx2 transcription factor, IGF-1 and Wnt signalling pathways...

In 2013, cardiovascular disease was responsible for 30.8% (800,937) of all 2,596,993 deaths, or approximately 1 of every 3 deaths while stroke caused about 1 of every 20 deaths in the United States [1]. To put it in context, about 795,000 people continue to have a new or recurrent stroke (ischemic or hemorrhagic) [1] in the USA. Mechanical vascular recanalization and thrombolysis with tissue plasminogen activator are the only clinically useful approaches available now for the management of ischemic stroke [2]...

BACKGROUND: In humans, orofacial pain has a high prevalence and is often difficult to treat. Magnesium is an essential element in biological a system which controls the activity of many ion channels, neurotransmitters and enzymes. Magnesium produces an antinociceptive effect in neuropathic pain, while in inflammatory pain results are not consistent. We examined the effects of magnesium sulfate using the rat orofacial formalin test, a model of trigeminal pain. METHODS: Male Wistar rats were injected with 1...

BACKGROUND: Epilepsy is one of chronic neurological disorders that affects 0.5-1.0% of the world's population during their lifetime. There is a still significant need to develop novel anticonvulsant drugs that possess superior efficacy, broad spectrum of activities and good safety profile. METHODS: α-Asaronol and two current antiseizure drugs (α-asarone and carbamazepine (CBZ)) were assessed by in vivo anticonvulsant screening with the three most employed standard animal seizure models, including maximal electroshock seizure (MES), subcutaneous injection-pentylenetetrazole (PTZ)-induced seizures and 3-mercaptopropionic acid (3-MP)-induced seizures in mice...

BACKGROUND: Brain-derived neurotrophic factor (BDNF) influences neuron differentiation during development as well as the synaptic plasticity and neuron survival in adulthood. BDNF has been implicated in the pathogenesis of schizophrenia and depression. Val66Met polymorphism and BDNF serum level are potential biomarkers in neuropsychiatric disorders. The aim of this study was to determine the effect of BDNF gene Val66Met functional polymorphism on serum BDNF concentration in patients with schizophrenia, during depression episode and in healthy control group...

Multiple sclerosis (MS) is a disease of suspected autoimmune origin leading to neurodegeneration. The disease pathomechanism is considered to be primarily based on neuroinflammation directed against myelin antigens caused by autoreactive T cells. MS etiology remains still unknown, which makes it difficult to create an efficient therapy, therefore, MS treatment targets mechanisms involved in disease pathology. In this review, we present the mechanism of action of three newly registered drugs for MS. Dimethyl fumarate (DMF) is an agent presenting a broad spectrum of action...

BACKGROUND: Penile corpus cavernosum is an extremely vascularized tissue and cavernosal smooth muscle tone is regulated by the balance between contractile and relaxant factor. We investigated the possible role of arachidonic acid/cyclooxygenase cascade, phosphodiesterase IV (PDEIV) and Rho-kinase in exogenous hydrogen sulfide (H2S)-induced relaxation in mouse corpus cavernosum. METHODS: The relaxant response to H2S (NaHS as exogenous H2S; 1-1000μM) were obtained in isolated mouse corpus cavernosum tissues which pre-contracted by phenylephrine (5μM)...

BACKGROUND: Vitamin D preparations reduce titers of thyroid antibodies in women with autoimmune thyroiditis. The same effect was induced by high-dose, but not moderate-dose-, statin therapy. No previous study has investigated the impact of concomitant treatment with a statin and vitamin D on thyroid autoimmunity. METHODS: The study included three matched groups of women with Hashimoto's thyroiditis and low vitamin D status. Groups B (n = 19) and C (n = 20) were treated with vitamin D (2000 IU daily)...

BACKGROUND: The combination of Opisthorchis viverrini (OV) infection and chemical carcinogen induces cholangiocarcinoma (CCA) in hamsters via inflammation-mediated mechanisms. Thus, suppression of inflammatory cells at the initial stages of CCA development would be of benefit. We aimed to investigate whether IL-17-producing CD4+ T cells (Th17) and CD4+ Foxp3+ T cells (Treg) are involved in the early stages of CCA genesis and can be targeted for suppression by melatonin. METHODS: Inflammation, an initial stage of CCA development, was induced in hamsters by a combination of O...

C-Phycocyanin (C-PC) has been shown to be promising in cancer treatment; however, although several articles detailing this have been published, its main mechanisms of action and its cellular targets have not yet been defined, nor has a detailed exploration been conducted of its role in the resistance of cancer cells to chemotherapy, rendering clinical use impossible. From our extensive examination of the literature, we have determined as our main hypothesis that C-PC has no one specific target, but rather acts on the membrane, cytoplasm, and nucleus with diverse mechanisms of action...

Depression is nowadays a major contributor to global burden of disease. The most commonly prescribed drugs influence monoaminergic pathways, mainly concentrating on serotonin. Unfortunately, there are several drawbacks associated with these drugs, namely late onset of action, risk of suicide and adverse effects: mainly nausea, vomiting and sexual dysfunction. Therefore there is still need for new drugs with possibly high efficacy and fewer side effects. In this paper selected compounds which inhibit serotonin reuptake by acting on the serotonin transporter (SERT) and various serotoninergic receptors are presented...

BACKGROUND: Low effectiveness of anti-melanoma therapies makes it necessary to search for new drugs that could improve or replace the standard chemotherapy. Fluoroquinolones are a group of synthetic antibiotics, used in the treatment of wide range of bacterial infections. Moreover, this class of antibiotics has shown promising anti-tumor activity in several cancer cell lines. The aim of this study was to examine the effect of ciprofloxacin on cell viability, apoptosis and cell cycle distribution in COLO829 melanoma cells...

BACKGROUND: N-acetyl-p-aminophenol (APAP, acetaminophen, paracetamol) is a widely used analgesic/antipyretic with weak inhibitory effects on cyclooxygenase (COX) compared to non-steroidal anti-inflammatory drugs (NSAIDs). The mechanism of action of APAP is mediated by its metabolite that activates transient receptor potential channels, including transient receptor potential vanilloid 1 (TRPV1) and TRP ankyrin 1 (TRPA1) or the cannabinoid receptor type 1 (CB1). However, the exact molecular mechanism and target underlying the cellular actions of APAP remain unclear...
