Intraoperative thermal mapping of mammary tumors in dogs

Abstract In this study, videothermometry’s application in detecting mammary tumors in dogs is explored in-depth. The research hypothesizes that this technique can effectively identify cancerous tissues during surgery by analyzing thermal patterns. The methodology involved comparing thermal imaging results from dogs with palpable mammary nodules against a control group, focusing on capturing real-time thermal patterns. Results were significant, showing distinct thermal patterns in carcinomas. This indicates videothermometry’s capability in accurately identifying micro metastases and differentiating between neoplastic and non-neoplastic changes. The study concludes that videothermometry has considerable potential in enhancing surgical precision, especially in tumor resection and safety margin definition, but emphasizes the need for further research to thoroughly understand the thermal signatures of various mammary tumors in dogs

New technique of intragastric sleeve: viability and survival in a pig model

Abstract Developing a less invasive, practical and cost-effective operative technique for obesity treatment represents a pressing need for our society. In this way, intragastric single port sleeve by endoplication was tested in six pigs during 18 weeks. Celiotomy was performed with animal placed in dorsal decubitus position. Single port gastrostomy was performed and double tobacco pouch sutures were made in fundic region, making a gastric sleeve. At the end, stomach layers and skin were closed in a conventional manner. Means and the standard deviations of surgical time were calculated. The procedure was simple and all animals survived; there were no significant blood loss and no intra and postoperative complications. The procedure was fast (67.4 minutes). The technique has the advantage of not requiring the use of mechanical sutures, making it less costly. The innovation of this procedure was the use of a single port gastrostomy device to perform an intraluminal sleeve. What made this technique less invasive were the use of a single port, nonmanipulation of the stomach intra-abdominally, ease of execution and no need of pneumoperitoneum. The new technique is acceptable and has reproducible viability, had a short procedure time without intra and postoperative complications

Absorção e redistribuição de boro em coqueiro-anão-verde Boron absorption and redistribution in green dwarf coconut tree

O objetivo deste trabalho foi verificar se ocorre redistribuição de boro em coqueiros (Cocos nucifera), quando a aplicação de ácido bórico é realizada na axila foliar ou no solo. Foram empregados os seguintes tratamentos com ácido bórico: 30 g aplicados sobre a axila da folha número 10; 60 g aplicados ao solo; e controle, sem aplicação. Foram realizadas duas aplicações de B, com um intervalo de cinco meses entre elas. A unidade experimental consistiu de duas plantas, com seis repetições, em delineamento inteiramente casualizado. Foram determinados os teores de boro nas folhas 2, 6, 10, 14 e 18, aos dois e quatro meses após a primeira aplicação de ácido bórico, e aos dois e cinco meses após a segunda aplicação. O boro se redistribuiu pela planta de coqueiro, independentemente da forma de aplicação. A elevação do teor de boro nas folhas persistiu por mais tempo, quando a aplicação de ácido bórico foi feita ao solo. As doses de ácido bórico aplicadas não causaram fitotoxidade, mesmo quando a aplicaçãofoi repetida após um curto período.<br>The aim of this work was to verify if boron redistribution occurs among the coconut palm (Cocos nucifera) fronds, when boric acid is applied on frond axils or on soil. The treatments with boric acid were: 30 g applied on the axil of frond number 10; 60 g applied to the soil; and a control without boric acid application. The B applications were repeated after five-month interval. The experimental unit consisted of two plants, with six replicates, in a randomized complete block design. Boron contents were determined in fronds number 2, 6, 10, 14 and 18, two and four months after the first boric acid application, and two and five months after the second application. Boron was redistributed in coconut plants, regardless of the application form. Increases in boron concentration in fronds persisted longer when boric acid was applied to the soil. The applied doses of boric acid hadno phytotoxity effect, even when the application was repeated after five months

Diversity of Brazilian Fungi

Abstract Knowledge about the Brazilian fungal diversity was, until 2010, recorded in few taxonomy and ecology publications, as well as in a handful of species lists. With the publication of the Catálogo de Plantas e Fungos do Brasil and the continued availability of an online list, it has been possible to aggregate this dispersed knowledge. The version presented here adds 2,111 species names to the 3,608 listed in 2010. A total of 5,719 species of fungi distributed in 1,246 genera, 102 orders and 13 phyla represents a considerable increase over the last five years, when only 924 genera and 78 orders were registered. Basidiomycota (2,741 species in 22 orders) and Ascomycota (1,881 species in 41 orders) predominate over other groups. The Atlantic Rainforest has the largest number of records, with 3,017 species, followed by Amazon Rainforest (1,050), Caatinga (999), Cerrado (638) and Pampa and Pantanal with 84 and 35 species, respectively. The Northeast region has the greatest richness (2,617 species), followed by Southeast (2,252), South (1,995), North (1,301) and Central-West (488 species). Regarding the States of the Federation, São Paulo with 1,846 species, Pernambuco with 1,611 and Rio Grande do Sul with 1,377 species are the most diverse
