title: Trueperella pyogenes as an abortion cause in a cow - case report

description: ABSTRACT Trueperella pyogenes is an opportunistic bacterium associated with mastitis, metritis and occasional abortion in bovines. Here we report an uncommon case of abortion by T. pyogenes in a cow. An aborted female Brahman bovine fetus, at 8 months of gestational age was submitted for anatomopathological examination and complementary diagnostic tests. Macroscopic findings at necropsy included large amounts of free serum-blood fluid and moderate fibrin deposition covering both the visceral pleura and pericardial sack. The lungs were diffusely reddened and markedly consolidated, showing widespread smaller than 1cm, hard, white nodules. Necrosuppurative pneumonia, fibrinopurulent pleuritis, and purulent placentitis were the main histopathologic alterations observed. Trueperella pyogenes was isolated from liver, lungs, abomasa contents and placental samples. All tissue samples were PCR-negative for Neospora caninum, Toxoplasma gondii and bovine viral diarrhea virus (BVDV). Although T. pyogenes is often involved in suppurative bronchopneumonia and abscesses formation, macro and microscopic lesions in the present report were compatible with those commonly attributed to Brucella abortus fetal infections. Trueperella pyogenes is an important bovine pathogen with a neglected zoonotic potential being responsible for infections that can mimic other diseases’ typical presentations.

title: Nutritional status of rice plants supplied with silicon in response to Pyricularia oryzae infection

description: ABSTRACT Considering the importance of silicon (Si) to increase rice resistance to blast, this study investigated the nutritional status of rice plants supplied with this element in response to Pyricularia oryzae infection. Plants were grown in nutrient solutions containing 0 and 2 mmol·L-1 of Si (referred to -Si and +Si plants, respectively). The area under blast progress curve decreased for +Si plants due to a significant increase of 714% on the foliar Si concentration in contrast to -Si plants. For +Si plants, the foliar N, P, K, Ca, Mg, Cu, and B concentrations were significantly lower in comparison to -Si plants. On infected plants, the foliar N, K, and Cu concentrations were significantly lower in comparison to noninfected ones. The foliar Zn, Fe, and Mn concentrations were significantly lower for -Si inoculated plants in comparison to -Si noninoculated ones. The foliar Mn and S concentrations were significantly lower for +Si inoculated plants in comparison to +Si noninoculated ones. The foliar Fe concentration was significantly lower for +Si inoculated plants in comparison to +Si noninoculated ones. Foliar Zn and Mn concentrations were significantly lower for +Si plants in comparison to -Si plants regardless of their inoculation with P. oryzae. Foliar Fe and S concentrations were significantly lower for +Si plants in comparison to -Si plants, respectively, for noninoculated and inoculated plants. Taken together, Si stood for itself in reducing blast symptoms without the need of high foliar concentrations of either macro or micronutrients that could affect plantgrowth.

title: Extracellular vesicles isolated from Trypanosoma cruzi affect early parasite migration in the gut of Rhodnius prolixus but not in Triatoma infestans

description: The protozoan Trypanosoma cruzi has the ability to spontaneously secrete extracellular vesicles (EVs). In this paper, T. cruzi EVs derived from epimastigote forms were evaluated during interaction with triatomine bugs Rhodnius prolixus and Triatoma infestans. T. cruzi EVs were purified and artificially offered to the insects prior to infection with epimastigote forms. No effect of EVs was detected in the parasite counts in the guts of both vectors after 49-50 days. On the other hand, pre-feeding with EVs delayed parasite migration to rectum only in the gut in R. prolixus after 21-22 days. Those data suggest a possible role of T. cruzi EVs during the earlier events of infection in the invertebrate host.

title: Clinical and therapeutic aspects of infection by Mycobacterium bovis in domestic cat - case report

description: ABSTRACT This article aims to report a case of Mycobacterium bovis infection in a six-month-old domestic cat, emphasizing its clinical and therapeutic aspects. The feline presented as history the intake of unboiled cow's milk and later developed signs of anorexia, non-productive cough and lymphadenomegaly. Additional imaging, hematological, cytological and polymerase chain reaction (PCR) tests were performed to elucidate the diagnosis. In the presence of Mycobacterium infection, treatment was instituted by the combination of three antimicrobials (Enrofloxacin 5mg/kg, Clarithromycin 10mg/kg, and Rifampicin 15mg/kg) orally every 12 hours, to which the animal responded positively, presenting significant decrease of the clinical signs, however after 60 days of treatment the cat died accidentally, hit by a car on the street. It is concluded that the treatment in cats affected by tuberculosis can cause improvement of clinical signs and that although rare in Brazil, this disease should be included as a differential diagnosis of infectious diseases in this species.

title: CHEMICAL ASPECTS IN THE INVESTIGATION OF SOME TYPES OF EFFLORESCENCE IN CULTURAL ASSETS

description: The preservation of Cultural Heritage is undoubtedly important for the society, and Conservation Science must dedicate itself to attempts to minimize the inherent processes of degradation to which cultural assets are susceptible. In this context, the evaluation of the chemical aspects of the composition of the objects and their relation with the environment where they are located are essential for the understanding of the decay signs observed, supporting the establishment of effective conservation strategies. These characteristics are demonstrated here by vibrational spectroscopy, scanning electron microscopy and microbiological analysis of efflorescences observed in two types of paintings: a tempera on canvas painting ("Barco com bandeirinhas e pássaros", Alfredo Volpi, 1955) and an oil mural painting of the Throne Room of the National Palace of Mafra (18th-19th century, Mafra, Portugal). The challenges involved in the investigation of the efflorescences are demonstrated in both cases, suggesting the occurrence of degradation processes of different origins: in Alfredo Volpi's tempera on canvas painting, the migration of substances from the preparation layer to the surface of the pictorial layer and microbiological colonization; and in the mural painting the migration of calcium salts from the constituent materials of plaster and of neoformation, besides associated microbiological colonization.

title: From yeast to humans: Understanding the biology of DNA Damage Response (DDR) kinases

description: Abstract The DNA Damage Response (DDR) is a complex network of biological processes that protect cells from accumulating aberrant DNA structures, thereby maintaining genomic stability and, as a consequence, preventing the development of cancer and other diseases. The DDR pathway is coordinated by a signaling cascade mediated by the PI3K-like kinases (PIKK) ATM and ATR and by their downstream kinases CHK2 and CHK1, respectively. Together, these kinases regulate several aspects of the cellular program in response to genomic stress. Much of our understanding of these kinases came from studies performed in the 1990s using yeast as a model organism. The purpose of this review is to present a historical perspective on the discovery of the DDR kinases in yeast and the importance of this model for the identification and functional understanding of their mammalian orthologues.

title: DNA repair genes in astrocytoma tumorigenesis, progression and therapy resistance

description: Abstract Glioblastoma (GBM) is the most common and malignant type of primary brain tumor, showing rapid development and resistance to therapies. On average, patients survive 14.6 months after diagnosis and less than 5% survive five years or more. Several pieces of evidence have suggested that the DNA damage signaling and repair activities are directly correlated with GBM phenotype and exhibit opposite functions in cancer establishment and progression. The functions of these pathways appear to present a dual role in tumorigenesis and cancer progression. Activation and/or overexpression of ATRX, ATM and RAD51 genes were extensively characterized as barriers for GBM initiation, but paradoxically the exacerbated activity of these genes was further associated with cancer progression to more aggressive stages. Excessive amounts of other DNA repair proteins, namely HJURP, EXO1, NEIL3, BRCA2, and BRIP, have also been connected to proliferative competence, resistance and poor prognosis. This scenario suggests that these networks help tumor cells to manage replicative stress and treatment-induced damage, diminishing genome instability and conferring therapy resistance. Finally, in this review we address promising new drugs and therapeutic approaches with potential to improve patient survival. However, despite all technological advances, the prognosis is still dismal and further research is needed to dissect such complex mechanisms.

title: DNA replication stress: oncogenes in the spotlight

description: Abstract Precise replication of genetic material is essential to maintain genome stability. DNA replication is a tightly regulated process that ensues faithful copies of DNA molecules to daughter cells during each cell cycle. Perturbation of DNA replication may compromise the transmission of genetic information, leading to DNA damage, mutations, and chromosomal rearrangements. DNA replication stress, also referred to as DNA replicative stress, is defined as the slowing or stalling of replication fork progression during DNA synthesis as a result of different insults. Oncogene activation, one hallmark of cancer, is able to disturb numerous cellular processes, including DNA replication. In fact, extensive work has indicated that oncogene-induced replication stress is an important source of genomic instability in human carcinogenesis. In this review, we focus on main oncogenes that induce DNA replication stress, such as RAS, MYC, Cyclin E, MDM2, and BCL-2 among others, and the molecular mechanisms by which these oncogenes interfere with normal DNA replication and promote genomic instability.

title: Critical Requirements for Nursing Practice in Rural Disasters Caused by Floods

description: ABSTRACT Objective: To identify critical requirements for nursing practice when responding to hydrological disasters in the rural area. Method: A descriptive, exploratory and qualitative study was developed. The Critical Incidents Technique was adopted. Twenty public health nurses who worked during the flood season in the years of 2014 and 2015 in a rural area in Southern Brazil were interviewed. Content analysis of the data was developed. Results: Critical requirements for nurses’ practice were derived from the situations (n=78), critical behaviors (n=98) and consequences to the population (n=43) and to the nurses (n=38) identified. Conclusion / Final considerations: Although the requirements could be related to the established international referential for nurses’ practice in disasters, some were described only in this study. They can contribute to the education and practice of nurses in primary health care, strengthening its capacity to face disaster situations by flood in the rural area.

title: RAMAN STUDIES OF BIS(PHENYLTERPYRAZINE)IRON(II) AND SUPRAMOLECULAR SPECIES WITH PENTACYANIDOFERRATE(II) IONS

description: The chemistry and spectroscopy of the iron(II) phenylterpyrazine complex, [Fe(phtpz)2]2+, were investigated in comparison with the analogous phenylterpyridine species, Fe(phtpy)2]2+, and the results indicated a strong electronic delocalization on the Fe(II) terimine chromophore encompassing the lateral pyrazyl groups. The delocalized nature of the molecular orbitals involved in the electronic excitation precluded a direct assignment of the pyridine and pyrazine vibrations in the complex. However, the capability of the terpyrazine complex to bind transition metal ions, such as the [Fe(CN)5]3- species, allowed to generate pentanuclear complexes displaying characteristic charge-transfer and resonance Raman spectra, revealing the pyrazine vibrations in the complex. The [Fe(CN)5]3- containing species also yielded polymeric compounds in presence of transition metal ions, exhibiting intervalence transfer bands and chemical similarities with the Prussian Blue complex.

title: Sucrose-free milk chocolate manufacture using bulking agents and a non-caloric sweetener

description: Abstract Sucrose is important in the production of chocolates because it contributes to its texture and sensory acceptance. The aim was to evaluate the effect of adding bulking agents and a non-caloric sweetener in the preparation of a sucrose-free milk chocolate. One control sample (with sucrose) and 11 treatments were taken varying the ratio between bulking agents (maltitol, polydextrose, inulin) and non-caloric sweetener (stevia), preserving the sweetness of control. Sensory acceptance of each treatment was evaluated by preference tests and taste profile. Principal component analysis (PCA) showed that formulations with maltitol and stevia (F7); and maltitol, polydextrose, inulin and stevia (F10) were the most similar to control in their sensory and quality properties. Polydextrose concentration at levels higher than 25% negatively affected the product texture. F10 showed higher fiber contribution due to the presence of inulin.

title: Processes for alcohol-free beer production: a review

description: Abstract Since the invention of beer by the Sumerian people in 5000 BC, alcohol was the main reason of the interest of consumers on beer. Only in the beginning of the 20th century alcohol-free beer was demanded and since then technology has advanced dramatically in the production of those beverages. The aim on alcohol-free beer production is to have products that taste similarly to their alcoholic equivalents, the sole absence of alcohol and low concentrations of esters and higher alcohols and the higher concentration of aldehydes create a “worty” organoleptic impression of those products. Alcohol-free beers can be obtained by the restriction of alcohol formation during fermentation, the use of special yeast strains that consume or don’t produce alcohol, the thermal removal of alcohol and by the removal of alcohol trough membrane processes. Membrane separated alcohol-free beers preserve more of the natural constituents of beer aroma and those products usually taste better than those obtained through other processes. Pervaporation techniques show a broad spectrum of use and can even be combined with other processes and perform the removal of undesired products or separation and recuperation of aromatic substances.
