Chemical, Physical And Oxidative Characteristics Of Broilers Meat Supplemented With Passion Fruit Seed Oil

Residues that could be discarded and transformed in high biological value protein is a measure of environmental preservation combined with the sustainability of animal production. This study evaluated the effects of the addition of passion fruit seed oil (PFSO) on broiler diet under the resistance of skin, physical-chemical characteristic, fatty acid profile and lipid oxidation (under storage) of breast meat obtained from these animals. There was improvement in the condition of skin rupture and meat tenderness; apart from that, oxidative reactions decreased, as PFSO was added to the diet (P<0.05). On the other hand, no effect on colour, pH, water retention capacity and weight loss on cooking (P>0.05) was observed. There was a linear effect increasing only for the margaric (C17:0) and cis10-Heptadecanoic (C17:1; P<0,05) fatty acids. However, due to the low amount of these fatty acids in PFSO, the found content was still low in all evaluated treatments. However, the evaluated levels did not contribute to the increase of the polyunsaturated fatty acid profile (P>0.05). Thus, it can be concluded that PFSO improves the resistance of broiler skin, which becomes softer and less susceptible to oxidative effects due to the oil’s antioxidant action, suggesting that it may be an ingredient that brings substantial benefits in the poultry industry

Distribution of alien tetrapods in the Iberian Peninsula

We present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and management plans, and research at the biological community level on alien species. This dataset summarizes inventories and data sources on the taxonomy and distribution of alien tetrapods in the Iberia Peninsula, comprising known locations from published literature, expert knowledge and citizen science platforms. An expert-based assessment process allowed the identification of unreliable records (misclassification or natural dispersion from native range), and the classification of species according to their status of reproduction in the wild. Distributional data was harmonized into a common area unit, the 10 × 10 km Universal Transverse Mercator (UTM) system (n = 6,152 cells). The year of observation and/or year of publication were also assigned to the records. In total, we assembled 35,940 unique distribution records (UTM × species × Year) for 253 species (6 amphibians, 16 reptiles, 218 birds and 13 mammals), spanning between 1912 and 2020. The species with highest number of distribution records were the Mediterranean painted frog Discoglossus pictus (n = 59 UTM), the pond slider Trachemys scripta (n = 471), the common waxbill Estrilda astrild (n = 1,275) and the house mouse Mus musculus (n = 4,043), for amphibians, reptiles, birds and mammals, respectively. Most alien species recorded are native to Africa (33%), followed by South America (21%), Asia (19%), North America (12%) and Oceania (10%). Thirty-six species are classified by IUCN as threatened in their native range, namely 2 Critically Endangered (CR), 6 Endangered (EN), 8 Vulnerable (VU), and 20 species Near Threatened (NT). Species maps are provided in DataSet1, as well R code and GIS layers to update them as new records are obtained.info:eu-repo/semantics/publishedVersio

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Número de cromossomos em populações de Achyrocline satureioides Lam. (marcela) do Estado do Rio Grande do Sul, Brasil

A caracterização citogenética das plantas medicinais de um país amplia as perspectivas da conservação da diversidade vegetal de espécies comumente utilizadas na medicina popular. Das espécies utilizadas medicinalmente no Brasil, algumas são nativas, dentre as quais se destaca, Achyrocline satureioides Lam. (marcela) da Família Asteraceae. Neste estudo, pela primeira vez, foi realizada a contagem do número cromossômico de populações de marcela, nativas do estado do Rio Grande do Sul. Foram coletadas sementes de cinco populações de marcela em seus locais de origem, as quais foram colocadas para germinar em ambiente controlado. Após a germinação, as pontas de raízes foram coletadas e pré-tratadas com paradiclorobenzeno durante cinco horas, fixadas em álcool absoluto:ácido acético glacial (3:1) por 24h a temperatura ambiente e, posteriormente, conservadas em álcool 70%, até o seu uso. A análise do número cromossômico foi feita a partir da confecção de lâminas das pontas das raízes, sendo que para o preparo das lâminas utilizou-se a técnica do esmagamento, hidrólise em HCl 5N por 10min, aplicação de ácido acético 45% durante 1min, esmagamento das pontas das raízes e coloração com orceína acética a 2%. Todas as populações estudadas apresentaram 2n=24 cromossomos, o que sugere ser esse o número diplóide da espécie
