OBJECTIVES: The menopausal transition is the time from the onset of menstrual changes until one year after the final menstrual period. During this phase, perimenopausal women experience a variety of health-related symptoms, which seemingly derive from declining level of estrogen secretion. It has long been recognized that some essential oils have the efficacy of alleviating menopausal symptoms. On the basis of this, it is possible that these essential oils have the potency to facilitate estrogen secretion in women...

A 26-year-old Japanese woman presented with adrenal insufficiency, and treatment was started with cortisone and fludrocortisone in 1975. A few years later, she presented with hypoparathyroidism and was diagnosed with autoimmune polyendocrine syndrome type I (APS I), and treatment with calcium and alfacalcidol was started. She was found to have subacute thyroiditis and relative adrenal failure in 2006. Her condition remained stable under treatment with cortisone, fludrocortisone, levothyroxine, calcium lactate, precipitated calcium carbonate and alfacalcidol...

HIV Infection resulting in AIDS remains serious global public health problem. In the fight with the global health problem plays a key role a simple, reliable and fast diagnostics. An important method in diagnostics is the identification and detection of viral capside p24 antigen levels. Fourth generation tests for the diagnostics of HIV infection simultaneously detect the presence of HIV antibodies and p24 antigen. Based on the monitoring of CD4 count, we can estimate the stage in which the infection is, and we can also suggest a therapeutic approach...

OBJECTIVES: Glutathione belongs to the family of small-molecular weight antioxidants like ascorbic acid, cysteine, α-tocopherol, uric acid, etc. These molecules play important role in the neutralization of free radicals and reactive oxygen species (ROS). Oxidative stress may lead to ageing and the development of large scale of pathological states of organism. This low molecular weight antioxidant´s level can alter under pathological conditions from reduced (GSH, thiols) to oxidized (oxidized glutathione -GSSG, disulfides) form...

OBJECTIVES: Extensive effort has been made to identify early markers of neurodegeneration as late stages have no chance of treatment. Recently, many experimental models have been used to study hallmarks of neuronal injury. One of them is the model of trimethyltin (TMT)-induced damage associated with cognitive decline, thus called a model of Alzheimer-like disease. OBJECTIVE AND METHODS: Our aim was to study neuronal transmission in hippocampal slices of male Wistar rats affected with a single dose of TMT (7...

OBJECTIVES: Ellipticine is an anticancer agent that functions through multiple mechanisms participating in cell cycle arrest and initiation of apoptosis. This drug forms covalent DNA adducts after its enzymatic activation with cytochrome P450 (CYP), which is one of the most important ellipticine DNA-damaging mechanisms of its cytotoxic effects. The improvements of cancer treatment are the major challenge in oncology research. Nanotransporters (nanoparticles) are promising approaches to target tumor cells, frequently leading to improve drug therapeutic index...

OBJECTIVES: The term "endocrine disruptor" (ED) is used for compounds that mimic or antagonize the effects of endogenous hormones. Synthetic estrogen 17α-ethinylestradiol (EE2) and a human carcinogen benzo[a]pyrene (BaP) are assigned as exogenous endocrine disruptors and an estrogenic hormone estradiol is a natural endogenous disruptor. Here, the potency of these three disruptors administered to rats individually and in combination to induce expression of cytochrome P450 (CYP) enzymes involved in their own metabolism (CYP1A1, 2C and 3A) in vivo was investigated...

OBJECTIVES: Chemical restraint of wild animals is practiced to accomplish intended procedures such as capture, clinical examination, collection of diagnostic samples, treatment and/or transport. Extra-label use of animal medicinal drugs is often necessary in wildlife because most approved therapeutics do not list wild species on the labelling. Here, we used cellular in vitro models, a cutting-edge tool of biomedical research, to examine cytotoxicity of anaesthetic agents in fallow deer and extrapolate these data for anaesthetic risks in wildlife...
