Characterisation of Neurospheres-Derived Cells from Human Olfactory Epithelium.

A major problem in psychiatric research is a deficit of relevant cell material of neuronal origin, especially in large quantities from living individuals. One of the promising options is cells from the olfactory neuroepithelium, which contains neuronal progenitors that ensure the regeneration of olfactory receptors. These cells are easy to obtain with nasal biopsies and it is possible to grow and cultivate them in vitro.

[Prospects for a passive acoustic research method in otorhinolaryngology].

The authors of the article reviewed acoustic research methods in otorhinolaryngology. All acoustic diagnostic methods are divided into active and passive. Active acoustic methods are based on the emission of acoustic vibrations, in some cases with the subsequent reception and processing of reflected vibrations.

[ENT care in the context of the new coronavirus infection COVID-19].

The spread of the pandemic of the new coronavirus infection COVID-19 inevitably makes adjustments to the medical care. Given that the main route of transmission is airborne, otorhinolaryngologists are at increased risk of infection. Based on the literature data of leading otorhinolaryngologists, as well as their own experience working with patients with the new coronavirus infection COVID-19, the authors present relevant recommendations on the organization of specialized otorhinolaryngological care in the context of the COVID-19 pandemic.

[Eustachian tube drug delivery to the tympanum in patients with otitis media with effusion].

There are no reliable data on the volume of the drug reaching the affected tympanic cavity during the catheterization of Eustachian tube (ET). Objective: to conduct an experiment and to study the effectiveness of administering a drug into the tympanic cavity of the middle ear using an original ear catheter, which allows catheterization of ET in the direction of its lumen. The study included patients with unilateral OME (=21, the duration of the disease from 2 to 3 months), who were recommended for the ventilation tube insertion.

[Observation of the intra-adenoid cysts in the nasopharynx].

The objective of the present study was to demonstrate the clinical significance and possibilities of diagnostics and treatment of the intra-adenoid cysts in the nasopharynx as exemplified by an original observation of an individual case. The cystic structures in the nasopharynx rarely manifest themselves clinically and are known to produce the non-specific symptoms. The patients admitted to the L.

A novel device for minimally invasive harvest of the sural nerve.

The sural nerve is ideal for autologous nerve reconstruction. Traditional open harvest techniques result in a large prominent scar, delayed ambulation and poor patient satisfaction. Accordingly, we have designed a neurotome device to exclusively harvest the sural nerve as a safe and effective alternative to traditional techniques.

Differences between two tight ADP binding sites of the chloroplast coupling factor 1 and their effects on ATPase activity.

Purified chloroplast ATP synthase (CF1) contains 1.2-2 mol of tightly bound ADP/mol of enzyme that resists removal by gel filtration or dialysis. CF1 was depleted of its endogenous nucleotide by treatment with alkaline phosphatase.
