Preliminary Study

The production of soluble toxic substances in broth cultures of these bacteria is well known. Berkefeld nitrates of such cultures are usually toxic for the rabbit upon intravenous injection. A review of the literature has been given by Ecker (1917, 1925) and by Branham (1925). Subsequent studies of these workers have shown that Berkefeld filtrates of synthetic medium (Braun and Cahn-Bonner, 1921) cultures yielded toxic substances inducing a similar reaction in the rabbit. Little is known concerning the nature of these substances beyond that they are relatively thermostabile; on dialysis of the broth culture nitrate the toxin is withheld within the collodium sac.

The article presents a review of the literature on the use of a variety of herbal remedies, showing pronounced immunotropic and adaptogenic properties, as correctors of violations of the immune status, developing in various pathological conditions. The information about the advantages of the use of drugs of plant origin in comparison with synthetic drugs, such as "soft" immunomodulatory effect, low toxicity, beneficial effect on metabolic processes, a wide range of biological effects due to the ability of herbal remedies to activate the functions of not only immune but also neuroendocrine systems. In addition, the article discusses some of the mechanisms of immunometabolic, antioxidant and adaptogenic effects of some herbal remedies, which serve as the basis for further study of their biological properties in order to expand the possibilities of phytopreparations in the arsenal of modern pharmacology.

A review of the literature discusses the deterioration of the hygienic state of the oral cavity and denture after the surgical, chemo-radiation and orthopedic stages of treatment for cancer of the maxillofacial region. The purpose of the study is to generalize and analyze modern research in the tield of the complex therapeutic effect of phytocomposites from medicinal plants, including anti-in^ammatory, antimicrobial, antioxidant, and oncoprotective components for use in oncological dentistry.Mouth rinses of plant origin, along with a pronounced local antimicrobial and cleansing effect, improve oral hygiene and have a phytotherapeutic effect on the body as a whole. Mouth rinses based on phytocompositions prevent the effects of chemoradiotherapy and the further development of the oncological process. The antioxidant, oncoprotective, immunomodulating and antimicrobial effects of plant ^avonoids, alkaloids and polysaccharides that systemically inhibit the process of metastasis are described.

Dense Vesicles

The sinus gland is a neurohemal organ located in the crayfish eyestalk and represents a storage site for neurohormones prior to their release into the circulation. The sinus gland contains 3 classes of dense, membrane-limited granules: 1) granules measuring less than 1000 Å in diameter, 2) granules measuring 1100-1400 Å in diameter, and 3) granules measuring 1500-2000 Å in diameter. Class 3 granules are the most electron-dense of the granules found in the sinus gland, while class 2 granules are the most abundant. Generally, all granules appear to undergo similar changes during release.Release of neurosecretory granules may be initiated by a preliminary fragmentation of the “parent granule” into smaller, less dense vesicles which measure about 350 Å in diameter (V, Figs. 1-3). A decrease in density of the granules prior to their fragmentation has been observed and may reflect a change in the chemical nature of the granule contents.

Freeze Etching

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.

Purpose We conducted a systematic review of the literature regarding adult telepractice services (screening, assessment, and treatment) from approximately 2014 to 2019. Method Thirty-one relevant studies were identified from a literature search, assessed for quality, and reported. Results Included studies illustrated feasibility, efficacy, diagnostic accuracy, and noninferiority of various speech-language pathology services across adult populations, including chronic aphasia, Parkinson's disease, dysphagia, and primary progressive aphasia. Technical aspects of the equipment and software used to deliver services were discussed. Some general themes were noted as areas for future research. Conclusion Overall, results of the review continue to support the use of telepractice as an appropriate service delivery model in speech-language pathology for adults. Strong research designs, including experimental control, across multiple well-described settings are still needed to definitively determine effectiveness of telepractice services.
