Vomeronasal system - structure and role in the biology of vertebrates, especially rodents
Autorzy:: Tlałka, Aleksandra
Opis:: Vomeronasal organ (VNO), also known as Jacobson organ has been described for the first time by Danish doctor Jacobson in 1811. The additional olfactory system is responsible for the perception of pheromones. Through years scientist did various studies on its presence, structure and function in different species of animals. The aim of this work is recapitulation of previous research and analysis of additional olfactory system, describe the structure, mechanisms of action and function in different groups of vertebrates.
Narząd womeronasalny (VNO), znany również jako organ Jacobsona został opisany po raz pierwszy przez duńskiego lekarza Jacobsona w 1811 roku. Dodatkowy układ węchowy odpowiada za percepcję feromonów. Przez lata naukowcy prowadzili różne badania dotyczące jego występowania, struktury i funkcji jaką pełni u poszczególnych gatunków zwierząt. Celem prezentowanej pracy było zgromadzenie dotychczasowej wiedzy i wyników badań nad tymże układem węchowym, opisanie jego struktury, mechanizmów działania oraz funkcji pełnionej u Vertebrata.

Opis:: This paper presents an objective method for early diagnosis of disorders and diseases of olfactory system. To achieve this goal the author designed a fragrance dosing prototype, which is synchronized with the dedicated recorder of olfactory evoked potentials. Automatic synchronization of registration of olfactory event-related potentials with dosing of stimulus fragrances enables precise determination of latency occurring between stimulation and response of the central nervous system. Obtained results allow to prove that developed prototype enables the evaluation of the olfactory system disorders in the context of neurodegenerative disorders. However it is necessary to establish a standardization procedures, before a wide implementation in a clinical practice. That is why the developed method requires a broader research which is an issue of a much larger group of patients and significantly longer duration of the study.

Opis:: The paper presents an analysis of objective evaluation of speech quality. As an example, the recovering process after stroke for patients with vascular lesion of a central nervous system has been taken into account. Application of neural networks gives possibility for objective evaluation of speech quality of patient suffering from disorder of speech motor.

Tytuł:: Antidepressant-like activity of magnesium in the olfactory bulbectomy model is associated with the AMPA/BDNF pathway

Opis:: Rationale. Numerous studies suggest agents that act on glutamatergic transmission as potential antidepressants. Preclinical and clinical evidence suggests that magnesium, an N-methyl-d-aspartate receptor blocker, may be useful in the treatment of depression. Objective. The aim of this study was to investigate the effects of magnesium on behavior; protein levels of GluN2A, GluN2B [N-methyl-d-aspartate receptor (NMDAR) subunits], GluA1 [α-amino-3-hydroxy-5 methyl-4-isoxazolepropionic acid (AMPA) subunit], phospho-Ser-831-GluA1 (P-S831), phospho-Ser-845-GluA1 (P-S845), and brain-derived neurotrophic factor (BDNF); and messenger RNA (mRNA) levels of GluN2A and GluN2B in different brain areas in the olfactory bulbectomy (OB) model of depression in rats. Methods. Magnesium was administered once daily for 14 days at three doses (10, 15, and 20 mg/kg, intraperitoneal) to sham and OB rats. Following treatment, open field and passive avoidance tests were performed in the sham and OB rats. After 24 h, the hippocampus, the prefrontal cortex (PFC), and the amygdala of rats treated with the most active dose (15 mg/kg) were harvested, and the protein and mRNA levels were determined. Results. Chronic administration of magnesium (15 and 20 mg/kg) reduced the number of trials required to learn passive avoidance and reduced the OB-induced hyperactivity. OB increased the P-S845 level in the hippocampus, which was reduced by magnesium treatment. Magnesium significantly increased the levels of BDNF, GluN2B, P-S831, and P-S845 protein (and mRNA) primarily in the PFC and the hippocampus in OB rats. Conclusion. For the first time, the present results demonstrate the antidepressant-like activity of magnesium in the OB animal model of depression and indicate the potential involvement of the AMPA/BDNF pathway in this activity.

Opis:: Exposure to phenol causes ultrastructural disorders in supporting and receptor cells in the peripheral segment of the olfactory organ of yellowfin (Cottocomephorus grewingkii) and in cells in peripheral blood of stone sculpins (Paracottus knerii), yellowfin and perch (Perca fluviatilis). Identical responses to phenol exposure in the blood cells were observed in endemic Lake Baikal fish and in nonendemic fish. Differences were found only in the rate and intensity of the recovery response. Fast activation of immune processes were found in the coastal nonendemic perch, but they were slow in the stone sculpin, a coastal endemic species.
