Relationship between the inflammatory infiltrate and the degree of differentiation of the canine cutaneous squamous cell carcinoma

AbstractThe inflammatory response may have pro or anti-neoplastic effects in tumors, depending on the histological type and malignancy level of the tumor. This study aimed to evaluate the profile of predominant inflammatory cells by immunohistochemistry in cutaneus squamous cell carcinoma (SCC) of dogs, comparing it with the degree of differentiation of the tumor. Twenty samples of SCC were analyzed. The tumors were histologically classified into two groups, differentiated SCC (SCCd=12) and undifferentiated SCC (SCCu=08). The tumor inflammatory infiltrate was determined by immunohistochemistry, in order to identify macrophages, lymphocytes and plasma cells. The comparison between groups, SCCd and SCCu, was not significant concerning the density of macrophages (P=1.0), T lymphocytes (P=0.335) and plasma cells (P=0.075). However, when comparing the inflammatory infiltrate in each group, the macrophages were the predominant cell type in both groups, a significant difference was found in the SCCd with plasma cells (P<0.0001). In the SCCu the difference occurred with lymphocytes (P<0.05) and plasma cells (P=0.0006). It could be concluded that the presence of inflammation in cases of SCC does not play a role in the differentiation of the neoplasm, since the inflammatory infiltrate was similar in both groups of SCC

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Estudo genômico do nível de infecção por Babesia bovis em bovinos da raça angus

A bovinocultura é um setor com importante destaque no agronegócio brasileiro. O carrapato Ripicephalus (Boophilus) microplus é responsável por perdas econômicas significativas aos pecuaristas e é vetor de hemoparasitoses como Anaplasma spp e Babesia spp. Sabe-se que os bovinos Bos taurus taurus são mais susceptíveis à infestação por carrapatos do que Bos taurus indicus. Acredita-se que o mesmo ocorra para a infecção por Babesia bovis. Neste trabalho, foram avaliados, em duas colheitas, 355 bovinos da raça Angus, pertencentes a uma fazenda de Uruguaiana-RS, nos quais foram realizadas contagens de carrapatos e colheitas de amostras de sangue para quantificação de B. bovis, pela técnica de qPCR, e genotipagem com chip de 150.000 marcadores SNP. Para qPCR utilizaram-se sequências iniciadoras que flanqueiam um fragmento do gene do citocromo B (mt-cytB), como oligonucleotídeos iniciadores. Após genotipagem dos bovinos com o chip Gene Seek Genomic Profiler™ (GGP-HD) da Illumina Infinium®, foi realizado imputação de genótipos, para recuperação de genótipos faltantes, e controle de qualidade. Foi realizada análise de associação genômica ampla (GWAS), para cada uma das características, infecção por B. bovis e resistência a carrapatos, através do método denominado “Single Step Genomic BLUP” (ssGBLUP). Todos os animais apresentaram infestação por carrapatos e infecção por B. bovis, determinada pela qPCR, e altos valores médios para ambas as características. Algumas regiões cromossômicas foram identificadas como significativas para as características estudadas, sendo que, sete dos cromossomos identificados no presente estudo já haviam sido descritos em outros trabalhos. Neste sentido, o presente estudo corrobora com outros resultados indicando que a técnica de qPCR é um método sensível de detecção de B. bovis em animais Angus e que as regiões genômicas identificadas como significativas podem ser importantes para a variação das características estudadas.The cattle industry is a sector with importance in the Brazilian agribusiness. The Ripicephalus (Boophilus) microplus is responsible for economic losses and is a vector for hemoparasitoses, such as Anaplasma spp and Babesia spp. It is known that the Bos tauros animals are more susceptible to infestation by ticks when compared with infestation in Bos indicus animals. It is believed that the same behavior keeps for infection by Babesia bovis. They were evaluated, in two collections, 355 Angus cattle, from a farm in Uruguaiana city, estate of Rio Grande do Sul, where were performed tick counts, quantification of B. bovis by qPCR and genotyping with a 150K chip. Were used as primers, in the qPCR, sequences that flanking the fragment of the cytochrome b gene. The technique was standardized and optimized using specimens of isolates of B. bovis. After genotyping, imputation was carried out, for recovery of missing genotypes, and quality control. Genome association analysis was performed (GWAS), to each of the characteristics, through the method called "Single Step Genomic BLUP" (ssGBLUP). All animals showed tick infestation and infection by B. bovis and high average values for both characteristics. Some regions on chromosomes were identified as significant to the characteristics tick infestation and infection by B. bovis, and seven chromosomes, identified in the present study, were already described in other studies. The present study agrees with other results indicating that the qPCR technique is a sensitive method to detecting B. bovis in Angus and genomic regions identified may be significant for the variation of these characteristics.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Pharmacological Potential of Flavonoids against Neurotropic Viruses

Flavonoids are a group of natural compounds that have been described in the literature as having anti-inflammatory, antioxidant, and neuroprotective compounds. Although they are considered versatile molecules, little has been discussed about their antiviral activities for neurotropic viruses. Hence, the present study aimed to investigate the pharmacological potential of flavonoids in the face of viruses that can affect the central nervous system (CNS). We carried out research from 2011 to 2021 using the Pubmed platform. The following were excluded: articles not in the English language, letters to editors, review articles and papers that did not include any experimental or clinical tests, and papers that showed antiviral activities against viruses that do not infect human beings. The inclusion criteria were in silico predictions and preclinical pharmacological studies, in vitro, in vivo and ex vivo, and clinical studies with flavonoids, flavonoid fractions and extracts that were active against neurotropic viruses. The search resulted in 205 articles that were sorted per virus type and discussed, considering the most cited antiviral activities. Our investigation shows the latest relevant data about flavonoids that have presented a wide range of actions against viruses that affect the CNS, mainly influenza, hepatitis C and others, such as the coronavirus, enterovirus, and arbovirus. Considering that these molecules present well-known anti-inflammatory and neuroprotective activities, using flavonoids that have demonstrated both neuroprotective and antiviral effects could be viewed as an alternative for therapy in the course of CNS infections

Erythrogram, leukogram, and acute phase protein reference intervals for healthy newborn Murrah buffalo calves (Bubalus bubalis) within the first month of life

Establishing of reference intervals (RI) for hematologic variables and blood serum acute phase proteins (APP) of healthy newborn buffaloes is an important tool for monitoring alterations during infection and inflammation. Considering the scarcity of published data on newborns, the aim of the study was to establish RI for hematologic variables and APP from healthy newborn buffaloes. Blood samples from 28 healthy Murrah buffalo calves, 10–30 days old, were selected to determine RI. Fourteen hematologic and four blood APP variables were analyzed. Before collection of blood samples, calves were subjected to physical examination (rectal temperature, degree of dehydration, and fecal consistency) and only calves that were considered healthy were included in the study. The Anderson-Darling test was used to assess normal distribution of values. The Dixon test and Tukey test were used to identify outliers. RI and 90% CI were determined using standard/robust methods and Box-Cox transformation. RI for variables analyzed were the following: (1) hematologic variables: RBC 7.5–12.9 × 106/μL, HGB 10.6–19.0 g/dL, packed cell volume 33.1–54.8%, mean corpuscular volume 36.2–50.6 fL, mean corpuscular hemoglobin 12.1–17.3 pg, mean corpuscular hemoglobin concentration 28.1–42.9 g/dL, platelets 361–1081 × 103/μL, WBC 6.56–18.2 × 103/μL, lymphocytes 4.15–12.8 × 103/μL, segmented neutrophils 0.950–10.6 × 103/μL, band neutrophils 0–0.160 × 103/μL, monocytes 0–0.754 × 103/μL, eosinophils 0–0.326 × 103/μL, and basophils 0–0.149 × 103/μL and (2) APP variables: fibrinogen 2.49-9.50 g/L, haptoglobin 0.02-0.56 g/L, serum amyloid A (SAA) 3.70-97.51 μg/mL, and C-reactive protein (CRP) 0.02-2.78  μg/mL. In conclusion, hematologic and acute phase protein RI have been documented and can be used as a physiologic database to help the interpretation of laboratory results of newborn buffaloes during infection and inflammation conditions

Diarreia epidêmica suína – uma enfermidade emergente na suinocultura mundial: Uma Revisão

The Porcine Epidemic Diarrhoea (PED) is an important cause of economic losses in the worldwide swine industry. Many countries of Europe and Asia have reported cases of the disease and recently a major outbreak has been affecting USA and Canada, showing that PED has reached the American continent. The infirmity is caused by a Coronavirus and has a clinical syndrome similar to Transmissible Gastroenteritis (TGE), the main clinical signs are watery diarrhoea, vomit, fast dehydration and high piglet mortality. The transmission occurs mainly through the fecal-oral route. Fomites, the introduction of breeders from infected herds and the international trade of live pigs are important ways of introducing the disease in regions where it is no present. Despite of being the main way to combat an outbreak, supportive treatment and vaccination are not very effective. The control, regulation and surveillance of the international trade of swines are the main forms of preventing the DES from reaching the Brazilian swine herds and also to avoid bigger losses to the national swine breeding.A Diarreia Epidêmica Suína (DES) causa importantes prejuízos na suinocultura mundial. Diversos países da Europa e Ásia já reportaram casos da enfermidade, e mais recentemente um grande surto tem assolado a indústria suinícola dos EUA e Canadá, evidenciando que a doença já chegou as Américas. A DES foi primeiramente relatada no Reino Unido em 1971, e seu agente identificado somente em 1978. A Doença é causada por um Coronavirus e apresenta síndrome clínica semelhante à Gastroenterite Transmissível Suína (GTS), com sinais clínicos como diarreia aquosa, vômitos, rápida desidratação e alta mortalidade em leitões. A transmissão da enfermidade acontece principalmente pela via fecal-oral, como consequência da introdução de reprodutores provenientes de propriedades com a enfermidade, inclusive que pode ser oriundo do comércio internacional de suínos vivos. Tratamento de suporte e a vacinação não apresentam bons resultados, porém são as únicas formas de se conseguir o controle seletivo dos surtos. Em locais indenes como o Brasil, a regulamentação sanitária e vigilância do trânsito internacional de suínos são as principais formas de se prevenir a entrada da enfermidade e assim evitar prejuízos incalculáveis à suinocultura nacional
