A Quality Improvement Network for Interdisciplinary Training in Developmental Disabilities.

Children with developmental disabilities (DD), such as autism spectrum disorder (ASD), have complex health and developmental needs that require multiple service systems and interactions with various professionals across disciplines. The growing number of children and youth identified with ASD or DD, including anxiety and depression, has increased demand for services and need for highly qualified pediatric providers. Federally funded Leadership Education in Neurodevelopmental and related Disabilities (LEND) programs across the United States address today's health care shortages by providing comprehensive, interdisciplinary training to providers from multiple pediatric disciplines who screen, diagnose, and treat those with ASD and DD.

Long-term outcomes of ruxolitinib therapy in steroid-refractory graft-versus-host disease in children and adults.

Acute and chronic steroid-refractory graft-versus-host disease (srGVHD) is a life-threatening complication of allogeneic stem cell transplantation. There are a number of reports on case series describing efficacy of ruxolitinib in both acute and chronic srGVHD. We conducted a prospective study (NCT02997280) in 75 patients with srGVHD (32 acute, 43 chronic, 41 adults, and 34 children).

The role of progestogen supplementation (dydrogesterone) in the prevention of preeclampsia.

Our goal was determine the effects of dydrogesterone supplementation to reduce the incidence of preeclampsia (PE) in early pregnancy (from 6 to 20 weeks of gestation). A total of 406 pregnant women were involved into the study. The Study group enrolled 169 women, supplemented with dydrogesterone at a dose of 30 mg/d 6-20 weeks of gestation compared with the control group (237 subjects) - without dydrogesterone supplementation.

[Structural and functional changes in the retinal layers in patients with primary glaucoma and possible means of retinoprotection].

Unlabelled: Glaucoma is one of the most severe forms of ophthalmic pathology which can lead to low vision and blindness. Therapy aimed only at reducing intraocular pressure (IOP) may be insufficient in patients with this disease.

Purpose: To study the structural and functional changes occurring in the retina and the effect of peptide bioregulator on the state of various retinal layers in patients with primary open-angle glaucoma (POAG).

[Young and old animals use different strategies for forming an immune response to infectious agents (Pseudomonas aeruginosa и Escherichia coli).].

Features of the immune response to injection of suspension of bacteria (Pseudomonas aeruginosa and Escherichia coli) in young (3 months) and old (20 months) Wistar rats at 3, 5 and 7 days after infection were investigated. The dynamics of the content of circulating immune complexes (CEC), complement C3 fragments, and the activity of oxygen-dependent and oxygen-independent phagocytosis were determined. It was shown that infection was accompanied by a multiple increase in the content of circulating immune complexes in young and, especially, in old animals.

miRNA profiling, detection of BRAF V600E mutation and RET-PTC1 translocation in patients from Novosibirsk oblast (Russia) with different types of thyroid tumors.

Background: The postoperative typing of thyroid lesions, which is instrumental in adequate patient treatment, is currently based on histologic examination. However, it depends on pathologist's qualification and can be difficult in some cases. Numerous studies have shown that molecular markers such as microRNAs and somatic mutations may be useful to assist in these cases, but no consensus exists on the set of markers that is optimal for that purpose.

Eye Movements as Indicators of Vestibular Dysfunction.

Virtual reality technologies are in wide use in sport psychology. An advantage of this kind of technology is the possibility to assess sportspeople's readiness to perform complex movements. This study is aimed at developing a method for the evaluation of vestibular function disturbances in young skaters.

Synthesis of ZnO tetrapods for flexible and transparent UV sensors.

ZnO tetrapods (ZnO-Ts) were synthesized in a vertical flow reactor by gas phase oxidation of Zn vapor in an air atmosphere. The morphology of the product was varied from nearly spherical nanoparticles to ZnO-Ts, together with the partial pressure of Zn and reaction temperature. MgO introduced during synthesis, increased the band gap, the optical transparency in the visible range, and also changed the ZnO-T structure.

Comparative evaluation of the depth of collagen and hyaluronic acid hydrolysis in vitro by collagenase and hyaluronidase preparations.

The molecular weights of collagen and hyaluronic acid solutions after their incubation with collagenase and hyaluronidase were evaluated by capillary viscosimetry. The results indicate high amylolytic activity of collagenase and the absence of proteolytic activity in hyaluronidase in an in vitro system.

Dynamics of hydration of cicatricial tissue during local therapy with collagenase preparations.

The components of complex dielectric permeability of cicatricial tissue at the frequency of 55 GHz were studied during local therapy of cicatrices with Fermenkol (a complex of collagenolytic proteases). Electrical characteristics of tissues in the microwave range were interpreted in terms of hydration parameters (total content of water in tissues and the ratio of structured and free water). The rightfulness of interpretations is discussed on the basis of the results of measurements of cell suspension models (native blood and its fractions brought to a standard hematocrit).

[The levels of nitrites and medium molecular-weight molecules in the blood of neonatal infants with posthypoxic cardiopathy].

A hundred and four neonatal infants underwent clinical and functional studies in early neonatality. The levels of nitrites and medium molecular-weight molecules were determined in cardiologically healthy neonatal infants and children with posthypoxic cardiopathy. The magnitude of increases in biochemical parameters was found to be associated with clinical type of cardiopathy: their level significantly elevates in transient myocardial ischemia, their values achieve the maximum level in neonatal pulmonary hypertension and in the presence of functioning fetal communications.

[Biochemical criteria in diagnosis of some causes of death].

The article presents biochemical indices of blood and tissues obtained at autopsy which can be used for diagnosis of strangulation asphyxia, poisoning with alcohol substitutes, hyperglycemic coma and hepatic insufficiency.

Role of sex hormones in cardiovascular resistance to atropine in rats at rest and during stress.

Castration of males and females reduces the sensitivity of cardiac chronotropic function to atropine and potentiates the vascular component in the reaction to atropine in females (during stress) and males (at rest and during stress). Our results show that estrogens and androgens increase the sensitivity of the cardiovascular system to cholinergic influences at rest and during stress.

Prenatal stress alters cardiovascular responses in adult rats.

Environmental factors in early life are clearly established risk factors for cardiovascular disease in later life. Most studies have focused on nutritional programming and analysed basal cardiovascular parameters rather than responses. In the present study we have investigated whether prenatal stress has long-term effects on cardiovascular responses in adult offspring.

[Effect of prenatal hyperandrogenism during pregnancy and on postnatal development of rats].

Hyperandrogenia was modelled in the female rats within the whole term of pregnancy by means of testosterone or dihydrotestosterone. Both androgens have been established to induce significant prenatal mortality and high percentage of mortinatus and postnatal mortality of progeny. Hyperandrogenization influenced negatively the sexual development and reproductive function of the female progeny versus the male one.

Collagenolytic protease preparations from invertebrates: biochemical aspects of medical and cosmetological applications.

Collagenolytic proteases from invertebrates, the active matter of new structure-destroying enzyme preparations (Collagenase from hydrobionts, Polycollagenase-K, Fermenkol), ensure deep hydrolysis of polypeptide substrates (native or partially denatured collagen types, elastin, fibrin, hemoglobin, and casein) that cannot be attained by collagenases and serine proteases. Biochemical properties of collagenolytic proteases from invertebrates, techniques and doses that may be important for elaboration and employment of preparations based on this complex are described.

Effects of collagenolytic protease preparations from invertebrates on the immune system.

We studied the effects of an active ingredient of new enzyme preparations containing collagenolytic proteases from various hydrobionts (Collagenase from hydrobionts, Polycollagenase-K, and Fermenkol). These substances in therapeutic doses did not affect the humoral immune response estimated by hemagglutination and local hemolysis in gel and caused no local irritation and allergic reactions after long-term application to the skin.

Collagenolytic protease preparations from invertebrates: experimental study of acute and chronic toxicity.

Toxicity of active matter of new structure-destroying enzyme preparations containing a complex of collagenolytic proteases from invertebrates (Collagenase from hydrobionts, Polycollagenase-K, Fermenkol) was studied. The absence of acute toxicity in skin application is proved, and LD(50) for intraperitoneal administration to mice and rats were determined. A long-term treatment with clinical doses under various types of application does not affect body weight gain, biochemical indices of the plasma, ECG, diuresis, and urine content.

The preparation of soft-tritium-labelled proteins and their application for the collagenolytic activity investigations.

Tritium-labelled Type I collagen from rat skin with specific activity of 8 mCi/mg and mixture of the crab hepatopancrease collagenolytic enzymes with specific activity of 25 mCi/mg have been obtained by the method of high-temperature solid-state catalytic isotope exchange (HSCIE) without loss of native features. Tritium-labelled Type I collagen kept its ability to form native fibrils being resistant to trypsin hydrolysis. Tritium-labelled collagenase keeps about 70% of its proteolytic activity.

[Vitamin D and calcium metabolism in relation to different levels of vitamins B6 and D].

The influence of vitamin B6 deficiency on some vitamin D-dependent processes was studied in animals. The following parameters changing in relation to the level of vitamin D providing were investigated: activity of alkaline phosphatase in the serum and small intestine mucosa, the levels of Ca, P and parathormone, concentration of vitamin D metabolites and enzyme activity; and only 25-hydroxyvitamin D (25-OVD) concentration in the blood serum, under conditions of combined vitamin B6 and D deficiency was significantly lower as compared to cases with vitamin D deficiency alone. In the presence of vitamin B6 deficiency recovery of 25-OVD level in the blood serum, after vitamin D administration to the animals, had a tendency to delay as compared to that in the animals provided with vitamin B6.
