The results indicate that olanzapine has proneurogenic effects on the adult rat SVZ, as the mean number of sex determining region Y-box 2 and doublecortin-positive cells increased significantly, while there was a similar tendency in the subgranular zone. Collectively, these results suggest that long-term treatment with olanzapine may stimulate neurogenic stem cell formation in the SVZ which supports adult neurogenesis.
Aim: To describe the case of rare benign lymphoproliferative disorder — pulmonary nodular lymphoid hyperplasia in the patient with previous pulmonary tuberculosis. Materials and Methods: In the case of pulmonary nodular lymphoid hyperplasia clinical, laboratory, instrumental and morphological examination was performed. Results: 44-year-old woman in 7 years after successfully treated infiltrative drug-susceptible tuberculosis of the right lung, was hospitalized with a suspected tumor of the left lung root. The patient underwent left-sided pneumonectomy with lymph nodes dissection. The results of histopathological and immunohistochemical studies evidenced on nodular lymphoid hyperplasia of the left lung. Conclusion: Pulmonary nodular lymphoid hyperplasia is a rare lymphoproliferative disorder of the lung with favorable prognosis. For the purpose of differential diagnosis, it is necessary to apply immunohistochemistry.
Ribbon synapses located exclusively within retinal, cochlear and vestibular connections belong to the most interesting cellular structures but their molecular nature and functions had remained unclear. The study has provided a descriptive morphological analysis of rat eye ribbon synapses using high-resolution transmission electron microscopy (TEM). An original collection of untypical, rarely present in the literature sagittal or tangential sections through the single RIBEYE domain of the particular ribbon have been delivered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
