Published: October 2021

Fundamentado no aporte teórico-metodológico da História Oral, este artigo analisa a trajetória inicial da Seleção Brasileira de Handebol Feminino desde sua primeira formação até a conquista da primeira vaga olímpica (1983 – 2000). Para tanto, foram realizadas seis entrevistas, sendo cinco com ex-atletas da Seleção e uma com um ex-técnico, as quais foram cotejadas com fontes documentais. A partir das análises, foi possível evidenciar que o início da Seleção se deu motivado pelo surgimento de competições continentais classificatórias para os Jogos Olímpicos e Campeonato Mundial. No que diz respeito ao seu desenvolvimento, percebemos que o movimento de se aproximar do handebol europeu, por meio dos intercâmbios, foram significativos para alcançar a hegemonia da modalidade no continente americano e adentrar nos Jogos Olímpicos.
SOMALIA – STUDIU DE CAZ PRIVIND FRAGMENTAREA UNUI STAT OMOGEN ETNIC ŞI CONFESIONAL
Authors: POPESCU Alba Iulia Catrinel 
Published: October 2021

Orice curs de geopolitică internă a statului începe prin a afirma că stabilitatea internă şi integritatea teritorială sunt rezultatul interacţiunii dintre forţele secesioniste, centrifuge, şi forţele unificatoare, centripete. Acelaşi curs de geopolitică mai spune că omogenitatea etnică şi confesională se înscrie în categoria celor mai puternice forţe centripete, alături de o formă cât mai rotundă a teritoriului statal, de centralitatea capitalei, de o distribuţie uniformă a infrastructurii de transport şi comunicaţii, de o distribuţie cât mai echitabilă a bogăţiei, de o puternică idee şi voinţă naţională. Somalia este un stat omogen etnic şi confesional. Mai mult, toţi aceşti etnici nu îşi arogă o altă identitate în afara celei somaleze şi cu toţii vorbesc limba somali, limba oficială a statului, alături de arabă – limba Coranului. În Somalia nu se înregistrează uriaşa diversitate lingvistică specifică altor state africane postcoloniale, nu există diferenţe cultural-civilizaționale, nu există discrepanţe majore în privinţa dezvoltării regionale şi a distribuţiei infrastructurii de comunicaţii şi transport în teritoriu. Şi, cu toate acestea, statul somalez reprezintă expresia noţiunii de stat eşuat, răvăşit de război civil, de secesionism, de piraterie maritimă, de terorism, de criminalitate organizată şi de insecuritate. În ultimii ani, Somalia a fost plasată constant în rândul celor mai periculoase destinaţii de pe glob. În prima jumătate a anului 2021, ea se situa pe locul al şaselea în clasamentul celor mai riscante destinaţii turistice, după Afganistan, Siria, Irak, Sudanul de Sud şi Yemen[i]. Care sunt cauzele secesionismului somalez şi ale prăbuşirii statului? Şi, dacă ar fi să ierarhizăm, în funcţie de intensitatea efectului, factorii secesionişti care acţionează pe teritoriul Somaliei, care ar fi ordinea acestora?

Background
Secondary salinized soil in greenhouses often contains excess nitrate. Inoculation of Bacillus megaterium NCT-2 with nitrate assimilation ability represents an attractive approach for soil remediation. However, the effects of NCT-2 on the structure and function of soil microbial communities have not been explored.

Methods
Greenhouse experiments were carried out to investigate changes in soil properties, Brassica chinensis L. growth, bacterial, and fungal community structure and function in response to NCT-2 inoculation.

Results
The NCT-2 inoculant significantly reduced the nitrate content in B. chinensis and inhibited the rebound of soil nitrate in the later stage. The shifts of bacterial community structure and function by NCT-2 was negligible, and a greater disturbance of soil fungal community structure and function was observed, for example the strong inhibitory effect on ectomycorrhizal fungi. These results indicated that the NCT-2 inoculant likely achieved the remediation effect in secondary salinized soil by shifting fungal community. The present findings add to the current understanding of microbial interactions in response to bacterial inoculation and can be of great significance for the application of NCT-2 inoculants in secondary salinized soil remediation.

Pseudomonas aeruginosa is one of the most widespread gram-negative microorganisms identified in the clinical samples and most common causes of hospital acquired infection. P. aeruginosa is affecting both indoor and outdoor patients throughout the world. Due to frequent mutation in P. aeruginosa highly resistant strain developed rapidly. The aim of the study to determine the prevalence of P. aeruginosa species in different samples isolated from a Tertiary care Hospital as well as determination their diverse antibiotic resistance pattern. This cross-sectional study was carried out to determine in-vitro resistance pattern of P. aeruginosa isolates to common antimicrobial agents by disc diffusion method. Various clinical samples were collected from Bangladesh Health Sciences Hospital (BIHS) General Hospital, Dhaka. This research was carried out in the Department of Microbiology of Bangladesh University of Health Sciences (BUHS). Isolation, identification and antibiogram were performed for P. aeruginosa following standard microbiological laboratory procedure. A total of 218 P. aeruginosa were isolated from 3062 different clinical specimens which are statistically significant (p<0.0001). Among the highest number of P. aeruginosa were isolated from outdoor patients 140 compare to Indoor patients which are significantly higher (p <0.013). In this study Male (68.3%) are more vulnerable to P. aeruginosa infection compare to females (31.7%) which is also statistically significant. Young people (less than 35 years) were more susceptible to P. aeruginosa infection which is also statistically significant (p< 0.01). The highest number of P. aeruginosa was isolated from wound (43.12%), followed by pus (40.33%), sputum (8.71%) urine (7.80%). The maximum number of P. aeruginosa in various samples was resistant to aztreonam and co-tromoxazole followed by cephalosporins, aminoglycosides, carbapenems. The most sensitive antibiotic was colistin of followed by gentamycin and tetracycline. To control the spread of resistant bacteria, it is disparagingly vital to have stringent antibiotic guidelines. The antibiotic susceptibility pattern of P. aeruginosa requires to be continuously monitored in specialized clinical units and the results readily made available to the clinicians to minimize the resistance.

Published: October 2021

Background: Current treatment with statins has become an integral part of vascular diseases but monotherapy has a significant residual event rate. Due to particularly one of the factor associated with atherogenic lipid phenotype that is characterized by a low high-density lipoprotein (HDL) cholesterol and increase in non-HDL cholesterol like Low-Density Lipoprotein (LDL). Omega-3 Fatty acids have demonstrated a preventiverole in primary and, particularly secondary cardiovascular diseases. Hence this study was planned to compare the efficacy of Atorvastatin alone with Atorvastatin and Omega-3 fatty acids in treatment in hyperlipidaemia patients.
Methods: The study was comparative, randomized, and prospective and open labeled conducted in MI patients. A total of 100 patients were selected based on inclusion and exclusion criteria. They were divided randomly into two Groups (Group–A and Group-B). Group-A was given Atorvastatin 10mg/day and Group-B was given Atorvastatin 10mg/day and Omega-3 fatty acids 600mg/day for 6 months. Follow up was done every month and efficacy was measured by assessing the lipoprotein levels in serum.
Results: The results were compared before treatment and after 6 months treatment.The levels were significantly decreased Total Cholesterol (TC), LDL, Low-Density Lipoprotein (VLDL), Triglycerides (TG) and HDL levels were increased in Group–A and Group-B. When these results compared between two Groups the HDL levels were increased also it shown high significance (<0.001) but there were no significance changes in other cholesterol levels.
Conclusion: The present study results showed that Atorvastatin and Omega-3 fatty acids treatment was more effective than Atorvastatin alone treatment in improving HDL-C levels from base line and it may have a additive effect in major coronary artery diseases.

Published: October 2021

AbstractA new design of a macro‐to‐micro interface that can be used for simple and reliable control of comprehensive microfluidic cell culture processes is introduced making microfluidic procedures easily accessible to biological laboratories. The novel macro‐to‐micro interface is evaluated by adapting a workflow for single‐cell, cell pair, and cell cluster encapsulation into hydrogel beads acting as 3D microenvironment with subsequent long‐term cultivation. For the first time, the coupling of single‐cell time‐lapse microscopy data with phenotypic (immunofluorescence) and genotypic (single‐molecule RNA fluorescence in situ hybridization) endpoint measurements as well as downstream compatibility in a single chip is shown. The presented platform will be a valuable tool for performing studies of dynamic biological processes coupled to a multiparametric endpoint characterization at the single‐cell level as well as for gaining more detailed mechanistic insights into gene function relationships and the behavior of biological systems.

Authors: Blanco Matías , Cembellín Sara , Agnoli Stefano , Alemán José 
Published: October 2021

AbstractA half‐sandwich ruthenium‐p‐cymene organometallic complex has been immobilized at Single Walled Carbon Nanotubes (SWNT) sidewalls through a stepwise covalent chemistry protocol. The introduction of amino groups by means of diazonium‐chemistry protocols leads the grafting at the outer walls of the nanotubes. This hybrid material is active in the transfer hydrogenation of ketones to yield alcohols, using as hydrogen source 2‐propanol. SWNT−NH2−Ru presents a broad scope, performing the reaction under aerobic conditions and can be recycled over 9 consecutive reaction runs without losing activity or leaching ruthenium out. Comparison of the activity with related homogeneous catalysts reveals an improved performance due to the covalent bond between the metal and the material, achieving turnover frequencies as high as 192774 h−1.

Published: October 2021

AbstractNeopentyl glycol (NPG) synthesis by condensation disproportionation of formaldehyde and isobutyraldehyde (IBD) with sodium hydroxide as catalyst was studied in a continuous‐flow microreactor under various experimental conditions, such as reaction temperature, residence time, and the molar ratio of reactants. All the conditions were determined by Box‐Behnken experimental design and the response surface method based on the preferred range selected by single‐factor experiments. For comparison, NPG was synthesized by condensation disproportionation of the same reactants in a batch reactor. The results showed that higher NPG yield and shorter residence time were achieved in a continuous‐flow microreactor than in a batch reactor when the other experimental conditions were similar.

Published: October 2021

AbstractVisual pathways of the brain are organized into parallel channels that code different features of the external environment. In the current study, we investigated the anatomical organization of parallel pathways from the superior colliculus (SC) to the pulvinar nucleus in the mouse. Virus injections placed in the ipsilateral and contralateral SC to induce the expression of different fluorescent proteins define two pulvinar zones. The lateral pulvinar (Pl) receives ipsilateral SC input and the caudal medial pulvinar (Pcm) receives bilateral SC input. To examine the ultrastructure of these projections using transmission electron microscopy, we injected the SC with viruses to induce peroxidase expression within synaptic vesicles or mitochondria. We quantitatively compared the sizes of ipsilateral and contralateral tectopulvinar terminals and their postsynaptic dendrites, as well as the sizes of the overall population of synaptic terminals and their postsynaptic dendrites in the Pl and Pcm. Our ultrastructural analysis revealed that ipsilateral tectopulvinar terminals are significantly larger than contralateral tectopulvinar terminals. In particular, the ipsilateral tectopulvinar projection includes a subset of large terminals (≥ 1 μm2) that envelop dendritic protrusions of postsynaptic dendrites. We also found that both ipsilateral and contralateral tectopulvinar terminals are significantly larger than the overall population of synaptic terminals in both the Pl and Pcm. Thus, the ipsilateral tectopulvinar projection is structurally distinct from the bilateral tectopulvinar pathway, but both tectopulvinar channels may be considered the primary or “driving” input to the Pl and Pcm.
