A novel water-soluble polymer nanocomposite containing ultra-small iron oxide nanoparticles, intercalated into a biocompatible matrix of 1-vinyl-1,2,4-triazole and -vinylpyrrolidone copolymer has been synthesized for the first time. The use of an original polymer matrix ensured effective stabilization of the crystalline phase of iron oxides at an early stage of its formation in an ultra-small (2-8 nm, average diameter is 4.8 nm) nanosized state due to its effective interaction with the functional groups of copolymer macromolecules.

Background: Sporadic multiple parathyroid gland disease is ¼ cases of primary hyperparathyroidism (PHPT). However, a single tactic for diagnosing and operating volume in patients with this variant of PHPT has not yet been developed. One of the possible directions in the search for pathogenetically substantiated methods of diagnosis and treatment is the study of the molecular genetic features of the disease and associated clinical and laboratory factors.

An antimicrobial polyacrylic silver salt (freshly prepared, stored for one year and model-aged) was studied by physical-chemical techniques for nanoparticle detection. In all cases, this salt represents a composite of radical-enriched macromolecules and silver(0) nanoparticles. As time passed, the initial small spherical nanoparticles were converted into larger non-spherical silver nanoparticles.

The antitumor properties of aqueous extracts of Inonotus rheades basidiomycete mushrooms were evaluated when the fungi were cultured on wood discs and wood shavings (birch) at 25 ± 1°C in the dark and under constant illumination with blue light (12.8 W/m). The aqueous fraction containing water-soluble polysaccharides was isolated and analyzed: WS-5 fraction cultured on wood discs under blue light illumination, WS-8 fraction grown under similar conditions on wood shavings; WS-6 fraction grown in the dark on wood discs; and WS-7 fraction grown under similar conditions on wood shavings.

A bright far-red emitting unsymmetrical -CF-BODIPY fluorescent dye with phenyl and pyrazolyl substituents was synthesized by condensation of trifluoropyrrolylethanol with pyrazolyl-pyrrole, with subsequent oxidation and complexation of the formed dipyrromethane. This BODIPY dye exhibits optical absorption at λ ≈ 610-620 nm and emission at λ ≈ 640-650 nm. The BODIPY was studied on Ehrlich carcinoma cells as a lysosome-specific fluorescent dye that allows intravital staining of cell structures with subsequent real-time monitoring of changes occurring in the cells.

Article Synopsis
  • A study examined the effectiveness of biologic early prophylaxis for preventing endoscopic post-operative recurrence (ePOR) in Crohn's disease patients after ileocecal resection (ICR).
  • It included 297 patients and found that ePOR occurred in about 41.8% of cases within one year, with varying rates across treatment groups: 40.2% for anti-TNF, 33% for vedolizumab (VDZ), and 61.8% for ustekinumab (UST).
  • The results indicated no significant differences in ePOR risk between the anti-TNF therapy and the other biologics after adjusting for patient factors, suggesting early prevention was effective for around 60% of patients regardless of

The presence of diethyl-, dibutyl-, and 2-ethylhexyl phthalates in spontaneous animal tumors was determined for the first time. Small-cell breast cancer of the dog and Ehrlich ascites carcinoma with the cells are particularly rich of these compounds. It is assumed that the level of phthalates in these cells is due to the activity of expression of nuclear receptors for estrogens and progesterone, as well as the peculiarities of the metabolism of xenobiotics.

A new hydrophilic polymeric nanocomposite containing AgNPs was synthesized by chemical reduction of metal ions in an aqueous medium in the presence of the copolymer. A new water-soluble copolymer of 1-vinyl-1,2,4-triazole and vinylsulfonic acid sodium salt (poly(VT-co-Na-VSA)) was obtained by free-radical copolymerization and was used as a stabilizing precursor agent. The structural, dimensional, and morphological properties of the nanocomposite were studied by UV-Vis, FTIR, X-ray diffraction, atomic absorption, transmission and scanning electron microscopy, dynamic and electrophoretic light scattering, gel permeation chromatography, thermogravimetric analysis, and differential scanning calorimetry.

A new original copper nanocomposite based on poly-N-vinylimidazole was synthesized and characterized by a complex of modern physicochemical and biological methods. The low cytotoxicity of the copper nanocomposite in relation to the cultured hepatocyte cells was found. The possibility to involve the copper from the nanocomposite in the functioning of the copper-dependent enzyme systems was evaluated during the incubation of the hepatocyte culture with this nanocomposite introduced to the nutrient medium.

In this case report the authors inform about late diagnosis of giant adenoma of the parathyroid gland with primary hyperparathyroidism (PHPT) and the development of fibrocystic osteitis with a «brown» tumor of the upper jaw. The patient has been under the care endocrinologist with type 2 diabetes mellitus and multinodular goiter for 8 years.The last 5 years there was a clinical manifestation of PHPT, but the diagnosis was made by an oncologist after the detection of a «brown» tumor of the upper jaw.

Introduction And Importance: Parathyromatosis is a rare cause of recurrent hyperparathyroidism. The main cause of this pathology is secondary implantation into the surrounding tissues of the damaged parathyroid gland (rough manipulation of the gland tissue) during the primary operation. Nowadays, parathyromatosis remain a difficult diagnostic and therapeutic task.

Background: At the time of seeking medical help, some patients have nodular/multinodular goiter of large and gigantic sizes, which leads to compression of the neck organs. In the structure of benign diseases, neck compression is diagnosed in 10% of cases, and tracheal narrowing is found in 84% of patients in this group. It was experimentally established that narrowing of the trachea leads to the development of hypertension in the pulmonary circulation.
