title: Synergy in penicillin, cephalosporin, amphenicols, and aminoglycoside against MDR S. aureus isolated from Camel milk

description: Abstract This study investigated the synergy testing of penicillin, cephalosporin, amphenicols, and aminoglycoside in the camel milk (n=768 samples), subsequently used for isolation of MDR S. aureus targeting mecA gene. Antibiotic susceptibility of S. aureus showed &gt;90% isolates were sensitive to ciprofloxacin and trimethoprim and resistant against oxacillin, ampicillin, and cefoxitin. Further, 50-85% of the S. aureus were sensitive to gentamicin, oxytetracycline, and chloramphenicol and resistant against cefotaxime, vancomycin, and cefixime. Minimum inhibitory concentration (MIC) of cefotaxime, (C) and ampicillin (A) in combination with gentamicin (G) was reduced by 99.34% and 70.46%, respectively, while with chloramphenicol (Ch), reduction was 57.49% and 60%, respectively. In addition, the Fractional Inhibitory Concentration Index (FICI) of G+A, Ch+C and Ch+G combinations showed synergy against 80%, 60%, and 30% of MDR S. aureus, respectively. Similarly, C+A and Ch+G displayed indifferent interaction against 70 % and 30% of isolates, respectively, while the later showed additive interaction against 10% of MDR S. aureus. Altogether, our results described effective combination of gentamicin and chloramphenicol with ampicillin and cefotaxime to combat MDR S. aureus.

title: Global therapies, local psychiatrists: shock treatment circulation and its implementation in Rosario, Argentina, 1936-1944

description: Abstract This article analyses the implementation of biological shock treatments in the Psychiatric Institute of Rosario, Argentina, during the interwar period. The aim is to illuminate the impact that a global phenomenon, referred to the strengthening of the discipline and the emergence of new therapies, had on an Argentinean psychiatric care space. Thus, it will analyse the relevance that budgetary limitations, the experimentation of alternatives and the presence of international experts had in the incorporation of therapeutic novelties. It is argued that the strategies deployed by the Institute to implement them expose the local nuances of a global phenomenon, as well as its contribution to the experimentation of treatments.

title: Japanese imperial psychiatry in Tokyo: two Korean immigrants in a psychiatric hospital, 1920-1945

description: Abstract During the first half of the twentieth century, Western psychiatry was quickly absorbed in Japan, particularly the versions from Germany and Austria. By 1940, over 130 psychiatric hospitals were caring for approximately thirty thousand patients in cities, while in rural areas about sixty thousand people still depended on family members for care. Japan’s empire expanded during this same period, and many immigrants came to the country. Growth in immigration from Korea was particularly important. Korean immigrants encountered Japanese psychiatric hospitals during the second quarter of the twentieth century, and this paper examines the complex nature of their hospital stays.

title: Characterization of new late-spring-frost-tolerant apricot hybrids: physical and biochemical fruit quality attributes, volatile aroma compounds

description: ABSTRACT: Late spring frosts is one of the most important restricting abiotic stress factors of apricot growing worldwide. In this study; some physical, biochemical fruit quality characteristics and volatile aroma compounds were determined in fresh fruit samples of thirteen late spring frost tolerant apricot hybrids recently obtained from Turkish apricot breeding programme. A wide variation was reported among apricot genotypes in all of the evaluated physical and biochemical fruit characteristics and also volatile aroma compounds.Fruit size varied between 27.2 and 60.5 g, total soluble solids between 13.6 and 17.4 %, total carotene 26.6 and 42.8 (mg.100 g-1), and total phenolics content 354.2 and 673.1 (GAE.100 g-1). A total of 42 flavor components belonging to various flavor compound groups were identified. The main volatile aroma compound groups detected in the assessed apricot genotypes were; aldehydes, ketones, esters, alcohols, terpenes, acids, and other compounds. Among the detected compounds; Hexanal, 2-Hexenal, 1-Hexanol, 2-Hexen-1-ol, Limonene were the most abundant compounds in terms of concentration. Hexanal varied between 55.8 and 528.5 µg.kg-1, and 2-Hexen-1-ol changed between 25.7 and 297.9 µg.kg-1 fresh weight. Correlation analysis revealed significant correlations among some aroma compounds and biochemical fruit quality characteristics. Significant correlations were reported for esters with titratable acidity (r=0.79) and total carotene (r=-0.61) and aldehydes were found as highly correlated with total soluble solids (r=-0.69). The results of the study will be beneficial in terms of food analysis, cultivation, and breeding studies of apricot.

title: Fermentative profile of corn silages with the inclusion of chemical additives or bacterial inoculant

description: ABSTRACT The objective was to evaluate the inclusion of chemical additives or bacterial inoculant in corn silage. The experimental design was completely randomized with five treatments: silage without additive; silage added with urea (3.0%); silage with limestone (3.0%); silage added with crystal sugar (3.0%); and silage with a bacterial inoculant. Five of them were opened during the fermentation process (15 days) to measure pH, and three were opened 60 days after ensiling to evaluate the ammonia nitrogen and organic acids content. For the pH at the end of the fermentation process, higher values were found for the limestone additive, followed by the silage with urea, which had higher participation of lactic acid, 19.06 ppm for limestone and 18.95 ppm for urea. Higher concentrations of acetic acid were observed in inoculant silages (18.49ppm) or silage without additive (18.46ppm). The ammonia nitrogen content was higher in the silage with urea (23.74mg dL-1), followed by the silage without additive (7.54mg dL-1), which also had the highest concentration of butyric acid (4.19ppm). The use of additives reduced the concentration of butyric acid in the silage. The bacterial inoculant was the most efficient in decreasing the pH of the ensiled material.

title: Recombinant expression and antigenicity of two peptide families of neurotoxins from Androctonus sp.

description: Abstract Background: Scorpion neurotoxins such as those that modify the mammalian voltage-gated sodium ion channels (Nav) are the main responsible for scorpion envenomation. Their neutralization is crucial in the production of antivenoms against scorpion stings. Methods: In the present study, two in silico designed genes - one that codes for a native neurotoxin from the venom of the Anatolian scorpion Androctonus crassicauda, named Acra 4 - and another non-native toxin - named consensus scorpion toxin (SccTx) obtained from the alignment of the primary structures of the most toxic neurotoxins from the Middle Eastern and North African scorpions - were recombinantly expressed in E. coli Origami. Results: Following bacterial expression, the two expressed neurotoxins, hereafter named HisrAcra4 and HisrSccTx, were obtained from inclusion bodies. Both recombinant neurotoxins were obtained in multiple Cys-Cys isoforms. After refolding, the active protein fractions were identified with molecular masses of 8,947.6 and 9,989.1 Da for HisrAcra4 and HisrSccTx, respectively, which agreed with their expected theoretical masses. HisrAcra4 and HisrSccTx were used as antigens to immunize two groups of rabbits, to produce either anti-HisrAcra4 or anti-HisrSccTx serum antibodies, which in turn could recognize and neutralize neurotoxins from venoms of scorpion species from the Middle East and North Africa. The antibodies obtained from rabbits neutralized the 3LD50 of Androctonus australis, Leiurus quinquestriatus hebraeus and Buthus occitanus venoms, but they did not neutralize A. crassicauda and A. mauritanicus venoms. In addition, the anti-HisrAcra4 antibodies did not neutralize any of the five scorpion venoms tested. However, an antibody blend of anti-HisrAcra4 and anti-HisrSccTx was able to neutralize A. crassicauda and A. mauritanicus venoms. Conclusions: Two recombinant Nav neurotoxins, from different peptide families, were used as antigens to generate IgGs for neutralizing scorpion venoms of species from the Middle East and North Africa.

title: COVID-19 and breast cancer screening in Brazil: a comparative analysis of the pre-pandemic and pandemic periods

description: Abstract The scope of this study was to evaluate the impacts of COVID-19 on breast cancer screening in Brazil. Data were collected from the Ambulatory Information System relating to “bilateral screening mammography” from January/2015 to December/2021. Analyses were performed by region and for Brazil. The average of exams in each month of the year was calculated based on 2015-2019 data, which was compared, monthly, with the number of exams in 2020 and 2021, obtaining the gross and percentage difference between these values. The same analysis was performed for the total number of exams in 2020 and 2021, individually, and for the two years combined. In 2020 there were reductions in the number of exams, which ranged from 25% (North) to 48% (Northeast), resulting in 1.749 million fewer exams than expected in the country (a drop of 44%). In 2021, the Midwest region presented a number of exams 11% higher than expected, while the other regions presented drops between 17% (North) and 27% (Southeast/South), resulting in 927 thousand exams fewer than expected in Brazil (reduction of 23%). In the joint analysis (2020/2021), reductions varied by region from 11% (Midwest) to 35% (Southeast/South), culminating in 2.676 million exams fewer than expected in Brazil (reduction of 33%).

title: Prospecting for candidate molecules from Conus virgo toxins to develop new biopharmaceuticals

description: Abstract Background A combination of pharmacological and biomedical assays was applied in this study to examine the bioactivity of Conus virgo crude venom in order to determine the potential pharmacological benefit of this venom, and its in vivo mechanism of action. Methods Two doses (1/5 and 1/10 of LC50, 9.14 and 4.57 mg/kg) of the venom were used in pharmacological assays (central and peripheral analgesic, anti-inflammatory and antipyretic), while 1/2 of LC50 (22.85 mg/kg) was used in cytotoxic assays on experimental animals at different time intervals, and then compared with control and reference drug groups. Results The tail immersion time was significantly increased in venom-treated mice compared with the control group. Also, a significant reduction in writhing movement was recorded after injection of both venom doses compared with the control group. In addition, only the high venom concentration has a mild anti-inflammatory effect at the late inflammation stage. The induced pyrexia was also decreased significantly after treatment with both venom doses. On the other hand, significant increases were observed in lipid peroxidation (after 4 hours) and reduced glutathione contents and glutathione peroxidase activity, while contents of lipid peroxidation and nitric oxide (after 24 hours) and catalase activity were depleted significantly after venom administration. Conclusion These results indicated that the crude venom of Conus virgo probably contain bioactive components that have pharmacological activities with low cytotoxic effects. Therefore, it may comprise a potential lead compound for the development of drugs that would control pain and pyrexia.
