Comparative analysis of the dispersion modeling and dose projection results performed under BARCO international project.

Radiological assessments on zones to take protective actions in case of a nuclear or radiological emergency involve a series of real-time forecasts of radiological impact on the public at various distances from the release point, using actual weather or forecast data, information on the source term or facility status, and primary radiation monitoring data. This practice is implemented during the operation of emergency centers around the world in order to promptly report the occurrence and possible consequences of radiological accidents in the country and abroad in the event of a possible transboundary impact. Since the Chornobyl disaster, a lot of emergency exercises, research programs and projects, in particular, benchmarking, have served as international platforms for improving modeling capacity in atmospheric dispersion.

Bioenergetic and Inflammatory Alterations in Regressed and Non-Regressed Patients with Autism Spectrum Disorder.

Autism spectrum disorder (ASD) is associated with multiple physiological abnormalities. Current laboratory and clinical evidence most commonly report mitochondrial dysfunction, oxidative stress, and immunological imbalance in almost every cell type of the body. The present work aims to evaluate oxygen consumption rate (OCR), extracellular acidification rate (ECAR), and inflammation-related molecules such as Cyclooxygenase-2 (COX-2), chitinase 3-like protein 1 (YKL-40), Interleukin-1 beta (IL-1β), Interleukin-9 (IL-9) in ASD children with and without regression compared to healthy controls.

Preliminary assessment of the radiological consequences of the hostile military occupation of the Chornobyl Exclusion Zone.

The full-scale invasion of Ukraine by Russian military forces on 24 February 2022 put the radiological well-being of the people in Ukraine under unprecedented threat. Apart from the risks linked to operating nuclear power plants, there was substantial evidence of looting of facilities of all kinds, including those holding radioactive materials, as well as the scope for physical disturbance of radioactively contaminated areas and waste storage facilities. The actions of Russian military personnel invading Ukraine through the territory of the Chornobyl Exclusion Zone (the ChEZ) were of serious concern.

A Bayesian approach to investment in innovation projects with the presence of fake innovators.

The paper proposes a game-theoretic model of interaction between investors and innovators, taking into account the existence of so-called "fake" innovators offering knowingly unprofitable projects. The model is a Bayesian non-cooperative, repetitive game with recalculated payments and partly unobservable player types. It allows quantifying the parameters of the strategy for all player types to find equilibrium solutions.

Risk Factor Analysis Between Newly Screened and Established Hepatitis C in GI and Hepatology Clinics.

Background: Several studies show inconsistencies in the rate of hepatitis C virus (HCV) detection among baby boomers (born 1945-1965). We conducted a cross-sectional HCV screening followed by a case-controlled comparison of the newly screened population with established HCV subjects.

Method: Enrollment was offered to subjects aged 40-75 at our gastroenterology and hepatology clinics.

Targeting VEGF-encapsulated immunoliposomes to MI heart improves vascularity and cardiac function.

Recent attempts at rebuilding the myocardium using stem cells have yielded disappointing results. The lack of a supporting vasculature may, in part, explain these disappointing findings. However, concerns over possible side effects have hampered attempts at revascularizing the infarcted myocardium using systemic delivery of proangiogenic compounds.

Internal capsule size in good-outcome and poor-outcome schizophrenia.

Converging lines of research suggest that white matter abnormalities may be central to the pathophysiology of schizophrenia. The purpose of this study was to examine regional white matter in the anterior limb of the internal capsules in patients with schizophrenia. The authors obtained high-resolution magnetic resonance imaging in 106 patients with schizophrenia and 42 age and sex-matched healthy comparison subjects.

[Relation between body fat mass and lipid status in the obese working population].

Introduction: Obesity can be defined as an excessive accumulation of health threatening body fat, caused by positive energetic balance. It can be classified according to body mass index as normal body mass, excessive body mass, significant obesity and extreme obesity. According to WHR (waist-hip ratio), it can be classified to android and gynoid type depending on fat tissue distribution.

Dynamical effects of an unconventional current-phase relation in YBCO dc SQUIDs.

The predominant d-wave pairing symmetry in high-temperature superconductors allows for a variety of current-phase relations in Josephson junctions, which is to a certain degree fabrication controlled. In this Letter, we report on direct experimental observations of the effects of a nonsinusoidal current-phase dependence in YBCO dc SQUIDs, which agree with the theoretical description of the system.

Introduction: Monitoring the health status of the employed in the meat industry "Neoplanta", a high prevalence of cardiovascular risk factors was observed. It was also observed that workers employed in the meat industry have specific dietary habits as a result of working practice. Their hypercaloric diet is with high dietary animal fat and protein intake.

[Obesity, hypertension and the lumbar syndrome in workers at the Neoplanta Meat Plant in Novi Sad].

Introduction: Obesity is more and more considered a serious medical problem associated with hyperlipoproteinemia, diabetes, cardiovascular disease, locomotor system diseases not only in the workers with hypertension and increased body fat, but also in the workers with lumbar syndrome. The objective of this study was to examine obesity and trends in frequency of lumbar syndrome and hypertension in workers employed in the meat industry, starting from the premise that obese workers are more prone to developing lumbar syndrome, hypertension or both diseases jointly.

Material And Methods: The following data: sex, age, years of employment in meat industry, body mass and height were filled out in the epidemiological questionnaire.

[Epithelioid leiomyoma of the stomach--its current diagnosis].

A case of a 62-years-old woman with mobile tumor in the upper abdomen is reported. With the contemporary methods of examination, including percutaneous thin needle biopsy, the diagnosis of epithelioid leiomyoma of the stomach was established. The patient was successfully treated surgically.

Use of high performance liquid chromatography for the structural identification of technetium-99m radiopharmaceuticals at the NCA level.

Technetium-99m (99mTc) complexes of dithiooxalate (dto) and maleonitriledithiolate (mnt) were prepared by ligand substitution of 99mTcNCl4-, dithionite reduction of 99mTcO4-, and ligand jexchange of [99mTc]gluconate (Sn). All complexes were characterized by high performance liquid chromatography (HPLC) on a C18 column using gradient elution with a tetrabutylammonium phosphate buffer (40-85% methanol). By performing HPLC of mixtures of the 99mTc complexes with structurally characterized 99Tc complexes of the ligands, it has been shown that at the no carrier added (NCA) level, 99mTcNCl4- labeling leads to the production of [99mTcN(dto)2]2- and [99mTcN(mnt)2]2-.

Simultaneous determination of decachlorobiphenyl, octachloronaphthalene and decachloro-1,4-dihydronaphthalene in mixtures, by HPLC.

Gas-liquid chromatography cannot distinguish between octachloronaphthalene and decachloro-1,4-dihydronaphthalene, because of the dechlorination of the latter during the chromatographic separation. High-pressure liquid chromatography on S50DS in the reverse-phase mode, with methanol as the solvent, has been successfully used in analytical (both qualitative and quantitative) and semi-preparative applications, involving the major products of the perchlorination of PCBs and PCNs: decachlorobiphenyl, octachloronaphthalene and decachloro-1,4-dihydronaphthalene.

[Functional radioisotope diagnosis in myocardial infarct].

The general and regional hemodynamics was studied in 50 patients with clinical, paraclinical and electrographic data on myocardial infarction in chronic and subacute stage via quantitative radiocardiography (ECG) and via the determination of the total coronary output (TCO). A significant reduction was radiocardiographically established of the indices of cardiac output as well as of the ejection fractions of the right and left ventricles, a manifestation of disturbed contractility of myocardium. TCO was substantially reduced (49.
