The publicism of Yevhen Yavorivskyi (1893—1954) in the Ukrainian periodicals
Authors: Nakonechna Zoriana
Published: February 2020

The journalistic and editorial activities of the Ukrainian pedagogue, journalist, active public figure Yevhen Yavorivskyi have been studied. The main topics raised in his publications have been identified. The press publications he cooperated with, have been comprehensively explored, specifically, the periodicals of the concern «Ukraiinska Presa».

The relevance of the topic is determined by insufficient research on the Yevhen Yavorivskyi’s activities. He greatly influenced the development of the Ukrainian press in a positive way. The Yevhen Yavorivskyi’s journalism was published on the pages of such Ukrainian periodicals: «Dilo» (Lviv, 1880—1939s), «Zhyttia i Znannia» (Lviv, 1927—1939s), «Ukrainske Slovo» (Yavoriv, 1929—1939s); also its publisher and the editor-in-chief), «Litopys Chervonoi Kalyny» (Lviv, 1929—1939s), «Zmahannia» (Sokal, 1931—1932s), «Litavry» (Kyiv, 1941), «Vinnytski visti» (Vinnytsya, 1941—1943s), «Dniprova khvylia» (Kremenchuk, 1941—1943s), «Lvivski visti» (Lviv, 1941—1944s), «Nashi Dni» (Lviv, 1941—1944s) and others. While in Lviv, Yevhen Yavorivskyi actively participated in the activities of the publishing house of I. Tiktor’s «Ukrainska Presa». He published his articles in the newspapers «Novyi Chas», «Narodnia Sprava», «Nash Prapor», and also had been responsible for the preparation of books of this concern. For many years, Yevhen Yavorivskyi actively cooperated with «Svoboda» — the Ukrainian newspaper in the USA. According to the reference sources, after leaving his native land (Ukraine) in 1944, he moved first to Innsbruck (Austria), then from 1950 he relocated to the USA). Over there he was a member of the editorial board of the «Vilna Ukraina» magazine (Detroit, since 1954). Moreover, we have managed to elucidate that he was a regular contributor to the «Narodna Volia» (Olyphant, 1911—1913; Scranton, 1913).

The main topics of Yevhen Yavorivskyi’s journalistic (memoir) publications were the reminiscences of 1917—1921s (at that time he served in the ranks of the Ukrainian Galician Army), the analysis of Ukrainian political events, the explanation of the necessity for enlightenment, specifically reading, as well as the organization of the Ukrainian educational institutions, informing about the current state as well as novelties in the Ukrainian book publishing.

Key words: Yevhen Yavorivskyi, magazine, article, journalism, memoirs, publishing concern, «Ukrainska presa», editor.
«True art» — «the need for the soul to express itself»: Hryhoriy Smolsky’s publicism
Authors: Sereda Oksana
Published: February 2020

The article deals with the journalistic achievements of the Ukrainian artist, local historian and publicist Hryhoriy Smolsky, analyzes the problems and genre of his articles in the Lviv press during the 1920s and 1970s. The long and thorny path of H. Smolsky to art was revealed. It is highlighted that this artist managed to restore his historical and artistic studios in Lviv only at the age of 28 years due to the then military situation in the Western Ukraine. It is emphasized that H. Smolsky was one of the five first students of the O. Novakivsky Art School and this was the defining moment in the formation of his artistic priorities. It became clear that the young artist’s collaboration with the Lviv press began in the late 1920s — he was part of the editorial board of «Literaturni Visti» and published two reviews on its pages. His publications about the history of the beginning and activities of the O. Novakivsky’s Art School in the «Novy Chas» newspaper and the «Svit» journal were rediscovered. It is accentuated on another facet of H. Smolsky’s talent — the writing of travel notes, which appeared in the 1930s in the «Dilo» and «Nazustrich» periodicals. It is highlighted that these features comprehensively revealed the artist’s journalistic talent. The H. Smolsky’s articles written during the German occupation, specifically in the «Lvivski Visti» diaries, were also introduced into the scholarly circulation and analyzed.

It is revealed that with the advent of Soviet rule, the artist kept «silent» for 15 years and was not present in artistic life. A number of publications by H. Smolsky of the late 1950s and 1970s were studied. They prove that the author was able to maintain his socio-cultural position even in the conditions of the rigid ideological framework. The artist’s significant contribution in illuminating the history of the O. Novakivsky Art School’s achievements is highlighted. It is summarized that H. Smolsky is a talented publicist, and although his journalistic legacy (rediscovered today) has only 22 articles, those are an important source of study of the Ukrainian artistic environment of Galicia in the 1920s–1940s.

Key words: H. Smolsky, journal, article, art, O. Novakivsky Art School.
Nostalgia for Chivalry and the Myth of the Knight: The Post-Medieval Reception of Arthurian Tales
Authors: BENOZZO FRANCESCO
Published: February 2020

Abstract The role of Renaissance writers in discovering Medieval Arthurian texts has been a crucial one, and somehow precedes the cultural process of Romantic authors. In this article a few narrative strategies and attitudes are analysed, with reference to authors like Pierre
Sala, Mossen Gras, Alain Bouchart, Jorge Ferreira de Vasconcelos, Niccolò degli Agostini, Luigi Alamanni, and with comparative considerations about Malory, Ariosto and Boiardo.
Analysing Nostalgia in Cross-Linguistic Perspective
Authors: FARESE GIAN MARCO , ASANO-CAVANAGH YUKO
Published: February 2020

Abstract This paper presents a contrastive semantic analysis of the English nostalgia, the Italian nostalgìa and the Japanese natsukashii adopting the methodology of the Natural Semantic Metalanguage. It is argued that: (i) emotion terms of different
languages reflect different and culture-specific conceptualisations of human feelings; (ii) the Anglo conceptualisation of feelings is not valid for all cultures; (iii) linguistic analysis is central to the analysis of human feelings. The paper challenges the claim made by some psychologists
that the English word nostalgia expresses a feeling which is “pancultural” and criticizes the use of English emotion terms as the basis for discussions on human feelings.

Published: February 2020

Five Saccharomyces cerevisiae strains (Chinese indigenous yeasts SC5, WC5, SC8, CC17 and commercial starter F15) were inoculated into Cabernet sauvignon grape must and fermented at pilot scale. For the first time, combination of 1H NMR, HS-SPME/GC-MS and HPLC-DAD-ESI-MS/MS metabonomic profiling techniques was performed to analyze the global chemical fingerprints of sampled wines at the end of alcoholic and malolactic fermentation respectively, then 13 non-volatile flavor compounds, 52 volatile organic aromas and 43 polyphenolic molecules were identified and determined correspondently. All principal component analysis (PCA) of two fermentation stages based on the analytical results of 1H NMR, HS-SPME/GC-MS and HPLC-DAD-ESI-MS/MS divided these strains into three clusters: (1) SC5 and SC8, (2) WC5 and F15 and (3) CC17. The wine fermented by indigenous yeast, CC17, showed a very unique chemical profile, such as low pH and high color intensity, reduced amino acids (including proline) and the lowest total higher alcohols levels, most of the fixed acids, glycerol, ethyl esters and anthocyanins concentrations. The statistical results indicate that CC17 strain possesses very special anabolism and catabolism abilities on such substances in grape juice and has potentiality to produce characteristic wines with high qualities.

Published: February 2020

Fresh Echinacea purpurea plant is a rich source of caffeic acid derivatives, which actively participate in the regulation of immune function. Herein, we describe a novel process for the production of fresh Echinacea purpurea juice rich in caffeic acid derivatives. This novel process includes steam heating (100°C, 15 min) before squeezing the juice to increase the recovery of caffeic acid derivatives from the flower or leaf by 1.5 to 3.7 fold. The recovery was further enhanced by 11–20% using ultrasonication at 500 W for 30 min. The flower, leaf, and root juice of Echinacea purpurea could be preserved for 4 weeks (4°C) or 6 months (−18°C) following ultra-high-pressure pasteurization (300 MPa, 15 min). Under these conditions, more than 90% of active cichoric acid was retained. Furthermore, the frozen-stored Echinacea purpurea juice exhibited similar or better immunoenhancement properties when measured by organ index, ear swelling, and carbon clearance test in mice compared with that of the positive control group (P < 0.05). Our results suggest that a combination of steam, ultrasound, and ultra-high-pressure treatment could serve as a superior process for the preparation of functional Echinacea purpurea juice.

The objective of present study was to analyze and compare the nephroprotective effects of petroleum ether extracts of seeds of Nigella sativa and Silybum marianum in Swiss albino mice. Petroleum ether extracts of seeds of Nigella sativa and Silybum marianum were administered (200 mg kg–1) orally for 14 days following one dose of cisplatin injection (16 mg kg–1 i.p.) on 4th day. Cisplatin toxicity was identified in mice by loss of body weight, reduced triglycerides levels, elevated blood glucose, blood urea nitrogen and creatinine levels (P < 0.05). Silybum marianum and Nigella sativa significantly enhanced the body weight (9%) of diabetic rats. Silybum marianum had significantly reduced the elevated blood glucose (–106%), and BUN levels (–9%) as compared to the Nigella sativa administration. Silybum marianum extract also significantly elevated the levels of triglycerides (257%) which were much reduced after the cisplatin injection. Histological study showed that the cisplatin treated group demonstrated the necrosis signs in the glomerulus of Bowman’s capsule, hyalinization and severe cellular damage. The animals administered with extracts showed nearly normal kidney architecture, however, the kidney tissues of Silybum marianum-treated animals showed some improvement with slight signs of cellular damages.

In this study, polyphenols were extracted from different parts (seed husks, seeds, young and old leaves) of Toona sinensis collected from Taihe District, Anhui province, China, through ultrasound-assisted extraction. During in vitro experiments, seed husks polyphenol extracts exhibited inhibitory effects against α-amylase and α-glucosidase up to 89% and 86.7%, respectively, and these values were slightly lower than the inhibitory rates of acarbose (91% and 90.5% on each enzyme) at the same concentrations. During in vivo experiments, treatment with high-dose seed husks polyphenol extracts (120 mg/kg body weight) significantly reduced the blood glucose levels, increased the glucose tolerance and insulin tolerance of diabetic mice (P < 0.05); In addition, the contents of triglyceride, total cholesterol, non-esterified fatty acid, high-density lipoprotein cholesterol and low density lipoprotein cholesterol in serum could be reduced, and the influence on total cholesterol was significantly different (P < 0.01). Moreover, the activity of superoxide dismutase and glutathione could be Obviously improved, the content of malonaldehyde could be reduced in serum, among those the effect on glutathione enzyme was extremely significant (P < 0.01). The results showed that the seed husks polyphenol extracts from T. sinensis had obvious hypoglycemic effect, and the mechanism of hypoglycemic might be related to the improvement of insulin sensitivity by repairing damaged islet cells. Meanwhile, antioxidant enzyme activity was improved, oxidative stress injury was reduced, and lipid metabolism was enhanced.

Published: February 2020

Breast cancer is most common tumour diagnosis for women worldwide. Over the last almost 40 years widespread adoption of mammographic screening has established Breast Conserving Surgery (BCS) followed by irradiation as the most practised treatment of choice. However, in absence of tools to determine the optimal quantum of tissue to be excised the debate continues for achieving a balance between the effectiveness of surgical intervention and the later stage personalisation of treatment, and so, a wide variation in practice is a common phenomena globally. We attempt to introduce a definite measure that determines efficacy of BCS while protecting aesthetic value of life for women affected with breast cancer.
74 mammography examinations and the surgical interventions of those women underwent for the management of breast cancer were used to compute the coefficient of lesion. In first step the lesion and the mammary gland proper are measured applying geometry. In the second step volume of tissue mass to be removed was calculated taking into account the measures from the 1st step and we present the coefficient of lesion mathematically. We empirically illustrated our methodological approach for determining the tissue mass to be excised.
Conventionally, it is assumed that if the volume of tissues to be removed does not exceed 25 % of the volume of the mammary gland, a Breast-conserving surgery (BCS), is performed, however, our empirical illustration demonstrated that the established decision making parameter is not tenable for determining the extent / type of surgery undertaken.
We have developed a coefficient aligned with the stage of the carcinoma and founded the base for developing a statistical (mathematical) model. Application of such a model accommodating tumor biology and patient characteristics shall not only provide intraoperative real time information to surgeons but also predict the prognosis of optimal surgical intervention of breast cancer.
Key words: coefficient of lesion for mammary gland, optimum surgical intervention, breast cancer, survival, probit regression model.
La deserción en la universidad argentina: algunos ejes para el replanteo de las políticas universitarias y de empleo
Authors: Aparicio de Santander Miriam
Published: February 2020

La presente comunicación remite a un estudio inserto en un programa de investigaciones más amplio sobre Evaluación de la Calidad de la Universidad, realizado en el marco del Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) y del Consejo de Investigaciones de la Universidad Nacional de Córdoba (CIUNC). El mismo resultó seleccionado en la Convocatoria efectuada por la Secretaría de Políticas Universitarias1 a efectos de profundizar en las causas de la deserción en Argentina. El programa incluye tres subproyectos cuyos ejes son (a) el éxito, (b) el retraso y (c) el fracaso (deserción) académico y socioprofesional. El que aquí nos ocupa tuvo por objeto dilucidar las raíces del fracaso en la Universidad por ser éste un problema que -pese a asumir hoy dimensiones dramáticas en el mundo y resultar preocupante en Argentina- ha sido insuficientemente estudiado desde una perspectiva integradora que recupere los factores estructurales e institucionales junto al actor psicosocial. Se elaboró al efecto un modelo sui generis que incluye 212 variables de diferente índole con el objeto de observar el peso relativo de ellas en su interacción autosostenida. Como es sabido, al amparo de hiperfuncionalismos, sociologismos y psicologismos, unas y otras han sido descuidadas a la hora de las explicaciones. La metodología fue cuantitativa-cualitativa haciéndose hincapié en el análisis de procesos antes que de resultados. Varias fueron las técnicas cualitativas usadas. El desarrollo del proyecto comportó un importante trabajo de campo (seguimiento en domicilio de una muestra de casi 3.000 desertores que hacen su ingreso a la UNC a partir de 1980 a 18 carreras). Los resultados fueron contrastados con los obtenidos dentro del mismo programa de investigaciones en dos submuestras: graduados y sujetos retrasados, lo que arroja especial luz sobre la importancia de los diferentes factores en lo que a logro se refiere. Los hallazgos acusan la franca incidencia de factores estructurales, institucionales y psicosociales en una interacción sostenida que aleja de determinismos mecanicistas y lecturas lineales. El balance global y “evaluación de lo evaluado” que aquí se ofrece invita a un replanteo en orden a la implementación de nuevas políticas y estrategias.
Una mirada al conocimiento científico desde el paradigma de la complejidad

Published: February 2020

“La enfermedad de la teoría está en el doctrinarismo y en el dogmatismo, que cierran a la teoría sobre ella misma y la petrifican. La patología de la razón es la racionalización, que encierra a lo real en un sistema de ideas coherente, pero parcial y unilateral, y que no sabe que una parte de lo real es irracionalizable, ni que la racionalidad tiene por misión dialogar con lo irracionalizable” (Morin, 1994, p. 34).

Published: February 2020

This study develops a new electrochemical method for quantification of Pb in soft water using stripping voltammetry with a glassy carbon electrode modified with the functionalized azulene: (2E)-2-(azulen-1-ylmethylidene) hydrazine carbothioamide (L) as a complexing polymer film. The optimized steps of the proposed method consisted in experimental establishing of four parameters, namely: reduction time; reduction potential; complexation time; pH in acetate buffer and phosphate buffer. The modified electrodes were prepared in L solutions (1mM) in acetonitrile (CH3CN) containing tetra n-butyl ammonium perchlorate (0.1 M TBAP) as supporting electrolyte. The electrochemical method includes four main operations: 1) polymeric film formation by controlled potential electrolysis (CPE) at 1.7V using a charge of 1 mC; 2) film conditioning in 0.1 M buffer acetate solution using cyclic voltammetry; 3) 25 min complexation time in a standard solution prepared from lead nitrate (II) using as matrix ultrapure water or a real sample; 4) stripping by differential pulse voltammetry method (DPV) in acetate buffer at pH 4.0, after 120 s reduction time at a reduction potential of -1.0 V. Determination time for a single standard solution or real sample was around 45 min. Evaluation of the method performance parameters (linearity, working range, detection limit, quantification limit, repeatability, and recovery) was done. It confirms that the proposed method is suitable to detect and quantify lead content over 1.2 �g/L in soft water samples.

Arachnoid cerebral cysts can create great anxiety to families of the affected child. In children prospective studies of arachnoid cerebral cyst series are focused on the surgical treatment and no medication associated tot this pathology was analysed until yet. We want to show how medication for neurological disorders found in children which have had also arachnoid cysts was used, and that not only surgery is the first line treatment in all types of arachnoid cysts.There are not extensive studies yet for the different contexts which are involving arachnoid cerebral cystsin children. This study was made for the first time in the cabinet of neurology from the Children Clinic Emergency Hospital Sfantul Ioan Galati in a 111 case series under clinic-imagistic surveillance and EEG between 2014-2017. A male predominance is seen as also a prevalence at the ages of 6-10 years of age and 2-5 years of age. Treatment were of different types due to the neurologic disorder which the children have had ( antiepileptic, neurotrophic, antiiinflammatory, nonsteroid and steroid and migraine treatment) after the international guidelines in use.The formulation of a diagnosis of epilepsy must be done with great responsibility because of many parioxistic nonepileptic events, where can exist associated arachnoid cysts, but we can have particulary family structures , because of the parents working places , so the waiting of the next paroxistic events and observing of the child is a wise attitude.But arachnoid cerebral cysts can be considered cerebral structural marker in some of the analysed cases.

The reproductive system of the vertebrates - mainly of the adult males -seems to be vulnerable to the action of endocrine disruptors. The aim of this study was to evaluate the effect of octylphenol (OP) on histological structure of testis in NMRI mice. The mice were divided in three groups (5 mice for each group) such as: control group (C - untreated); vehicle group (V - treated with a mixture of ethanol and corn oil 1:10) and experimental group (E � treated with OP in concentration of 160 mg/kg body weight). The solution of OP was prepared in ethanol, administered by subcutaneous injection in the thigh region (1 ml total volume), for seven consecutive days. For histological examination, after slaughtering, the testes were fixed in 10% neutral formalin, embedded in paraffin, sectioned to a thickness of 5 �m and stained with Mallory�s trichrome method. Microscopic analysis reveals in the individuals from the C and V groups, the normal morphology of the seminiferous tubules. In the case of individuals in the E group, treated with OP, in the testicular parenchyma occurs changes consisting in: detachment of the seminiferous tubule epithelium, mild proliferation of germ cells, the presence of apoptotic bodies among the cells of seminal line, diffuse hyperplasia of the Leydig interstitial cells and hypertrophy of the peritubular capillary. Experimental data obtained in this study demonstrated that the treatment with octylphenol induces irreversible changes in the testicular parenchyma with the disruption of spermatogenesis process.

Authors: Arsenescu Georgescu Catalina , Anghel Larisa
Published: February 2020

The aim of our study was to evaluate the impact of new LBBB on left ventricular systolic function and arrhythmic risk in patients with acute myocardial infarction and unicoronarian lesion. We prospectively studied the patients with acute myocardial infarction with and without LBBB and unicoronarian lesion after a mean of 16.51 � 2.41 months from the onset of acute coronary event. We observed a higher risk of ventricular premature beats and left ventricular systolic disfunction in patients with left bundle branch block. Also, the presence of left bundle branch block (F = 3.64; p [ 0.005; partly h2= 0.33) and the duration of the QRS complex (F = 4.17; p [ 0.005; partly h2= 0.36) was statistically significantly correlated with the value of left ventricular ejection fraction. Almost a double number of patients with left bundle branch block had an ejection fraction below 30%, despite an early revascularization. Patients with acute myocardial infarction and left bundle branch block represent a relatively small group but with an increased risk of malignant ventricular arrhythmias and left ventricular systolic dysfunction, and they should therefore benefit from a promptly and appropriately treatment in order to improve long term outcome.

Published: February 2020

This research was conducted to study fatty acids composition, especially content of n-3 FA; c9,t11-CLA (rumenic acid) and t11-C18:1 (vaccenic acid) and health lipid indices of milk according to the feeding practices in sheep. The exeperimental diets consisted of: P - pasture without any diet supplementation, PC - pasture + standard concentrate (500 g/d), PCs - pasture + fat-enriched concentrate (camelina seed-based concentrate: 500 g/d). Camelina seeds (Cs - Camelina sativa L) were used to increase the beneficial FA concentration in milk fat. PC diet as compared to P diet increases daily milk yield and the content of milk fat, but it adversely affects the quality of milk fats. Fat in the milk of PC ewes had a higher content of hypercholesterolemic FA, while the polyunsaturated FA (PUFA) concentration decreased (p [ 0.001). The use Cs in the concentrate mixture (PCs diet) increased by more than double the c9,t11-CLA, C20:5n-3 (EPA), C22:6n-3 (DHA), C18:3n-3 (ALA) and t11-C18:1 (VA) (p [ 0.001) in milk fat, without any negative effects on milk yield and composition. Beneficial changes of health lipid indices milk fat (atherogenic index, thrombogenic index, n-6/n-3 FA) were detected when the diet of ewes was supplemented with fat-enriched concentrate (PCs group) because of high concentration of c9,t11-CLA, n-3 FA which has sanogenic properties. It is concluded that, when pasture quality and availability do not limit dairy production, supplementation of grazing ewes with concentrate mixture is not recommended, because compromised the milk FA profile. The using camelina seeds in strategies for supplementing the diet of ewes on pastures is a good choice both for the daily milk yield and even more so for the sanogenetic quality of milk fats.

Methicillin-resistance phenomenon regarding Staphylococcus aureus which is often met as etiologic agent of severe systemic infections with oral-maxillofacial portal of entry imposes the first-line therapeutic schemes readjustment in patients with significant risk factors. Minimum inhibitory concentration (MIC) determination for every isolated S.aureus strain is useful for the antibiotherapy guiding, in order to choose the appropriate antimicrobial substances and to avoid the selection of resistant mutants. There have been studied and tested 9036 bacterial strains isolated from patients hospitalized in the Sf.Spiridon Emergency County Hospital between 2013-2016. Minimum inhibitory concentrations (MIC), MIC 50 and MIC 90 values were determined for the following antibiotics: Penycilline, Erithromycin, Oxacylline, Tetracycline, Gentamycin, Tobramycine, Kanamycin, Ryfampicyn, Trimethoprim-Sulfamethoxazole, Ofloxacine, Ciprofloxacine and Vancomycin.The classification of each identified bacterial strain into sensitive or resistant was accomplished according to the breakpoints recommended by CLSI 2016 (Clinical and Laboratory Standard Institute). We considered intermediately susceptible isolates as being resistant. S.aureus antibioresistance was high to tetracycline, erythromycin and kanamycin, with elevated MIC 90 values (64�g). The rate of resistance to penicillin in the case of S.aureus was 94.7%. The lowest MIC values regarding Pseudomonas aeruginosa were for imipenem, meropenem and colistin and the highest ones for piperacillin-tazobactam, ceftazidime and amikacin. Third generation cephalosporins demonstrated their inefficiency in the staphylococcal infections� treatment as a consequence of an increasing resistance to this category of betalactams. Vancomycin remains a saving in-hospital therapeutic option in the case of MRSA implication, next to teicoplanin and linezolid.

Nowadays opportunistic infections are not the only threat in the case of HIV-infected patients, being upstaged by microbial or fungal severe infections, especially after the introduction of ultimate generation antiretroviral therapy. The aim of this study is to investigate the factors that are predictive for an unfavourable prognosis and the causality of severe sepsis in HIV-immuno-depressed hosts. The study included 42 HIV-seropositive patients, found out in the evidence of HIV/AIDS Regional Centre from Iasi, that have been diagnosed with severe sepsis with confirmed etiology between the January 2012 and December 2016. The study group was subdivided in two subgroups: the first batch represented by twenty patients HIV-infected in childhood (pediatric cohort) and the second batch represented by 22 patients HIV-infected in adulthood. The medium age at the time of the sepsis diagnosis was significantly lower in the first group compared to the second one (25.0�2.58 vs 34.9�11.8). The lowest CD4 cells levels were noted in the case of patients infected in childhood, being in C2/C3 disease stage. The bacterial etiology was variate in both studied subgroups, with the predominance of Escherichia coli (33.3%), Staphylococcus aureus meticilino-rezistent (26.2%) and Streptococcus pneumoniae (19%) strains. The liver and kidney disfunctions were frecvently present in HIV-infected patients with severe sepsis (n=28 respectiv 31). A high percentage of patients associated criptocococcosis meningoencephalitis (33.3%), the most affected were those from the second subgroup (40.9%). Systemic infections in HIV-seropositive patients presumes an additional risk of unfavourable outcome, especially in the context of non-adherence and non-compliance to ARV-therapy and a long-term HIV infection history.
Setting Some Milestones when Modelling Cell Gene Expression Regulatory Circuits Under Variable-volume Whole-cell Modelling Framework. II
Authors: Maria Gheorghe , Scoban Andreea Georgiana
Published: February 2020

While in the first part of the study, general concepts of the novel whole-cell simulation of metabolic processes in living cells are presented, by considering a variable-volume modelling framework, in the present paper exemplification is made for approaching several case studies when building-up modular model structures, for instance by developing modular kinetic representations of the homeostatic gene expression regulatory modules (GERM) that control the protein synthesis and homeostasis of metabolic processes. Past and current experience with GERM linking rules is presented in order to point-out how optimized globally efficient kinetic models for the genetic regulatory circuits (GRC) can be obtained to reproduce experimental observations. Based on quantitative regulatory indices evaluated vs. simulated dynamic and stationary environmental perturbations, the paper exemplifies with GERM-s from E. coli, at a generic level, how this methodology can be extended to characterize the GERM module efficiency, species connectivity, and system stability.
Interventional Clinical and Chemical Studies in Romania, Legal Guarantees
Authors: Simiti Ionut Vida
Published: February 2020

The risks of medical treatment are due not only to the patient�s anatomic and physiological state, but also to the scientific and technical level of medicine when providing the medical service, which may progress through interventional clinical studies. In Romania, between 2012-2016 were issued annually between 192 and 221 authorizations for performing interventional clinical studies, the majority being phase III studies and almost half in oncological, respiratory and nervous diseases, although the pathology which represents the main mortality cause is the cardiovascular one. The goal of this study is the analysis of the legal requirements for the patients to participate to these interventional clinical studies, within the ample proceedings that aim to the approval of chemical substances as human use drugs. At present, the legal guarantees for interventional clinical studies are offered by the EU Regulation 536/2014 of the European Parliament and of the Council of 16 April 2014 regarding interventional clinical studies with drugs for human use, which through art. 4-27 of the Regulation settles a preliminary authorization procedure meant to avoid any deviation from public order and good morals, and through art. 28-36 of the Regulation protects the patient�s private interest through a special regulation of his consent when accepting an unusual clinical practice.
AGRICULTURA EMPRESARIAL, POVOS E COMUNIDADES TRADICIONAIS:

O objetivo deste artigo é refletir sobre os mecanismos de dominação simbólica presentes no discurso dos representantes dos grandes proprietários de terra e empresários agroindustriais quando dirigidos aos povos e comunidades tradicionais. Busco identificar a natureza de seus argumentos e perceber como as “diferenças fundamentais” (Gramsci, 1972) se exprimem na linguagem dessas elites e de seus porta-vozes. De uma perspectiva mais geral, procuro mostrar que, como parte do processo de constituição do agronegócio, a ampliação da representação e a diversificação de interesses em comum entre grandes proprietários de terra, produtores rurais e empresários agroindustriais organicamente constituídos incidem diretamente no modo como eles atuam junto aos seus adversários, em especial diante da luta dos povos indígenas e comunidades tradicionais e seus aliados e na produção de uma linguagem de classe orientada por três grandes argumentos, que se complementam e são acionados dependendo da conjuntura: (1) a desqualificação dos adversários e de seus aliados; (2) a concepção de que as criticas a eles endereçadas são preconceituosas, falsas e equivocadas; e (3) o discurso produtivista e apologético do agronegócio.

Em contextos de ambientalização de conflitos sociais na Amazônia, a roça permanece a duras penas co- mo símbolo vivo e prática tradicional, constituinte de identidade e territórios, de campesinatos que resistem ao autoritarismo da vigilância e do controle ambiental do Estado. Em áreas de reforma agrária sob cobertura florestal na chamada Transamazônica, como no emblemático caso do Programa de Desenvolvimento Sustentável (PDS) Virola-Jatobá no município de Anapu/PA, enquanto vigia-se e se controla a prática da roça, o manejo florestal comunitário e os sistemas agroflorestais são alternativas legalmente permitidas para conciliar desenvolvimento rural e conservação ambiental. Esta pesquisa-ação interdisciplinar identifica e discute distintas interpretações sobre impactos de políticas públicas ambientais vinculadas à vigilância e controle do desmatamento nesse PDS. Evidenciam-se extremos diferenciais nas relações de poder, que demandam transformações não apenas de ordem técnica ou jurídica, mas sobretudo política. Conclui-se que, na relação desse campesinato com a sociedade e o Estado, em meio à proliferação de normativas ambientais e crescente vigilância e controle, são necessárias novas competências aos atores enfocados pela pesquisa. Essas competências incluem processos de territorialização na transformação dos sistemas de produção, em que se vislumbra uma aproximação entre a roça e o manejo florestal comunitário.

A literatura, ao tratar da motivação de jovens filhos de agricultores para o trabalho no espaço rural, mostra dilemas entre “sair e ficar” no estabelecimento familiar. Contrariamente, os nossos primeiros contatos no campo indicaram apenas o desejo de permanência. Motivadas por esse contraste, investigamos a questão e, neste artigo, analisamos a motivação de jovens para trabalhar na sua região de origem. Amparada na sociologia rural e do trabalho, a pesquisa foi realizada por meio de um estudo de caso na localidade de Perseverança, São Domingos do Capim (PA). Observações e entrevistas com jovens e seus pais constaram nos procedimentos de pesquisa. Concluímos que, em sua maioria, os jovens têm interesse em continuar vivendo e trabalhando na localidade, mas o desejo de autonomia pessoal e financeira motiva-os a buscar uma formação profissional para conquistar um trabalho assalariado ou mais remunerado perto de casa ou no seu próprio estabelecimento. Há variação de motivações para o trabalho segundo o recorte de gênero, mas a condição de precariedade alcança todos os jovens entrevistados.
