Depression associated with poor general medical condition, such as post-stroke (PSD) or post-myocardial infarction (PMID) depression, is characterized by resistance to classical antidepressants. Special treatment strategies should thus be developed for these conditions. Our study aims to investigate the mechanism of action of 2-morpholino-5-phenyl-...

CRH system integrates responses to stress challenges, whereas antipsychotics may impinge on this process. Effect of haloperidol (HAL) and aripiprazole (ARI) on chronic mild stress (CMS) induced neurobehavioral and CRH/CRHR1 system changes was studied in functionally interconnected rat brain areas including prefrontal cortex (PFC), bed nucleus of th...

L-17 is a thiadiazine derivative with putative anti-inflammatory, neuroprotective, and antidepressant-like properties. In this study, we applied combined in silico, ex vivo, and in vivo electrophysiology techniques to reveal the potential mechanism of action of L-17. PASS 10.4 Professional Extended software suggested that L-17 might have pro-cognit...
Article
The field of ageing research has been rapidly advancing in recent decades and it had provided insight into the complexity of ageing phenomenon. However, as the organism-environment interaction appears to significantly affect the organismal pace of ageing, the systematic approach for gerontogenic risk assessment of environmental factors has yet to b...

Congenital lung masses (CLM) the rare group of causes of acute respiratory insufficiency (RI) in newborns include congenital airway pulmonary malformation (CAPM), congenital overinflation, bronchopulmonary sequestration, and bronchial atresia. The presenting group consists of 13 newborns who were admitted to the Neonatal Department of Intensive Med...
Article
The healthy development of the fetus depends on the exact course of pregnancy and delivery. Therefore, prenatal hypoxia remains between the greatest threats to the developing fetus. Our study aimed to assess the impact of prenatal hypoxia on postnatal development and behavior of the rats, whose mothers were exposed to hypoxia (10.5 % O2) during a c...
Article
Prenatal hypoxia (PH) has negative consequences on the cardiovascular system in adulthood and can affect the responses to additional insults later in life. We explored the effects of PH imposed during embryonic day 20 (10.5% O 2 for 12 h) on circadian rhythms of systolic blood pressure (BP) and heart rate (HR) in mature male rat offspring measured...

Indole derivatives such as isatin (a natural compound), cemtirestat, stobadine, and its derivatives (synthetic compounds) are known to have numerous positive effects on human health due to regulation of oxidative status. The aim of the study was to assess radical scavenging capacities of these compounds and explore their potential protective effect...

Full-text available
Perinatal hypoxia is still one of the greatest threats to the newborn child, even in developed countries. However, there is a lack of works which summarize up-to-date information about that huge topic. Our review covers a broader spectrum of recent results from studies on mechanisms leading to hypoxia-induced injury. It also resumes possible primar...
Article
This article reports the relationship between prenatal respiratory infections such as human respiratory adenovirus (HRAV) and/or human respiratory syncytial virus (HRSV) and orofacial clefts (OFC). Specific antibodies against HRAV and HRSV were investigated serologically (ELISA) in newborns with orofacial cleft and their mothers. The results were c...

SMe1EC2M3 is a pyridoindole derivative related to the neuroleptic drug carbidine. Based on the structural similarities of SMe1EC2M3 and known serotonin (5-HT), norepinephrine, and dopamine reuptake inhibitors, we hypothesized that this compound may also have triple reuptake inhibition efficacy and an antidepressant-like effect. PreADMET and Dragon...

We investigate the long-term effect of very-low dose exposure to a mixture of six pesticides associated with hydrophilic vitamin deficiency on the neurobehavioral outcomes of rats. Two hundred Wistar rats were divided into four groups, two control groups, a vitamin sufficient control group and a vitamin deficiency control group and 2 test groups, a...
Article
Two important aspects of cardiac adaptive response to pregnancy have been studied in normal as well as hypoxic conditions: (1) intercellular signaling mediated by myocardial connexin-43 (Cx43) that is crucial to synchronize heart function; (2) extracellular signaling mediated by matrix metalloproteinase-2 (MMP-2) that is an early marker of extracel...
Article
The paper published by Ruczyszky and Liu (2017) reports on the biosynthesis of ergothioneine under both aerobic and anaerobic conditions. We would like to suggest a hypothesis as to what could be the reason that microorganisms on the Earth synthesized ergothioneine under anaerobic conditions.
Article

Handling is a form of experience which can result in physiological changes depending on the period of postnatal age when performed. There is a lot of evidence about the positive effect of neonatal handling, but a lack dealing with handling of adult rats. Behavioral changes and memory deficits are present in dementia-like disorders. In the present w...
Article
Depression during pregnancy and in the post-partum period is a growing health issue. Venlafaxine, a representative of serotonin and noradrenaline reuptake inhibitors, is used to treat a wide spectrum of mood disorders. However, the limited number of prenatal and perinatal studies raises the question about the long-term consequences of venlafaxine t...

5-hydroxymethyl-2-furfural (5-HMF) is a thermal decomposition product of saccharides. There are two main ways for the formation of 5-HMF. First, 5-HMF is forming during Maillard reaction and second, during thermic dehydration of saccharides under acid conditions. Significant parameters of 5-HMF formation are temperature, time, pH, water activity, t...

Article
Objectives: There are several models of depression. Chronic unpredictable mild stress (CMS) appears to have the greatest validity, although it is often being criticized for low reliability. Methods: Male Wistar/DV rats were used in this study to assess our modified 2-week model of CMS as a combination of psychosocial, physical and metabolic stre...

The idea of antioxidant therapy attenuating Alzheimer disease (AD) neuropathology starts to be attractive. Animal models are often used in these studies. An AD-like model of trimethyltin (TMT)-induced neurodegeneration, targeting the hippocampus, involves neuronal cell death and cognitive impairment. Effect of the pyridoindole SMe1EC2 (3×50 mg/kg)...

Article
It is well known that the names of discoverers are commonly used in medical terminology, especially in everyday use. The advantage of an eponym is that a complex description of a certain syndrome, surgical procedure, manifestations of a particular disease, or its details, can be expressed in a single word (Holomáňová & Brucknerová 2003). Current of...
Article
Safety is a rising challenge to the community. It is clear that emerging new compounds and technologies require the responsibility not only from the regulators but also from the industry and people themselves. In the last 100 years over 70,000 new chemicals have been brought into commercial production and released to the environment. The current im...
