Factors Affecting False Lumen Thrombosis In Type B Aortic Dissection. / Fatores que Afetam a Trombose da Falsa Luz na Dissecção Aórtica Tipo B.

BACKGROUND: Complete thrombosis of the false lumen facilitates remodeling of type B aortic dissection (TBAD). Morphological characteristics affect thrombosis in the false lumen. OBJECTIVES: Discuss the factors present before admission that influence false lumen thrombosis in patients with TBAD. METHODS: We studied 282 patients diagnosed with TBAD in our hospital between January 2008 and December 2017. We divided the subjects into a thrombotic group and a non-thrombotic group based on whether any thrombus was detectable in the false lumen. We analyzed the differences between the two groups with respect to clinical data, the vertical length of the dissection, and the diameter of the aorta. P values < 0.05 were considered statistically significantly different. RESULTS: Significant differences between the thrombotic group and non-thrombotic group were found with respect to age (53.92 ± 11.40 vs. 50.36 ± 10.71, p = 0.009) and proportion of patients with renal insufficiency (7.83% vs. 16.38%, p = 0.026). In zones 3-9, the true lumen diameter of the thrombotic group was significantly larger than in the non-thrombotic group (p < 0.05). Binary logistic regression analysis showed that true lumen diameter in zone 5 and renal insufficiency were independent predictors of false lumen thrombosis. CONCLUSIONS: Age and renal function were associated with thrombosis in the false lumen. Potentially, the difference between the diameter of the true lumen diameter and that of the false lumen may influence the thrombosis of the false lumen.

FUNDAMENTO: A trombose completa da falsa luz facilita a remodelação da dissecção aórtica tipo B (DATB). As características morfológicas afetam a trombose na falsa luz. OBJETIVOS: Discutir os fatores pré-admissão presentes, que influenciam a trombose da falsa luz em pacientes com DATB. METODOLOGIA: Ao todo, 282 pacientes diagnosticados com DATB em nosso hospital foram estudados, no período entre janeiro de 2008 e dezembro de 2017. Os indivíduos foram divididos em um grupo trombótico e um grupo não trombótico, com base na detecção de qualquer trombo na falsa luz. Analisamos as diferenças entre os dois grupos com relação aos dados clínicos, o comprimento vertical da dissecção e o diâmetro da aorta. Valores de p < 0,05 foram considerados estatisticamente diferentes de modo significativo. RESULTADOS: Diferenças significativas entre o grupo trombótico e o grupo não trombótico foram encontradas com relação à idade (53,92 ± 11,40 vs. 50,36 ± 10,71, p = 0,009) e proporção de pacientes com insuficiência renal (7,83% vs. 16,38%, p = 0,026). Nas zonas 3­9, o diâmetro da luz verdadeira do grupo trombótico foi significativamente maior do que no grupo não trombótico (p < 0,05). A análise de regressão logística binária mostrou que o diâmetro da luz verdadeira na zona 5 e a insuficiência renal foram preditores independentes de trombose da falsa luz. CONCLUSÕES: A idade e a função renal estiveram associadas à trombose na falsa luz. Potencialmente, a diferença entre o diâmetro da luz verdadeira e o da falsa luz pode influenciar na trombose da falsa luz.

Bovine TMEM95 gene: Polymorphisms detecting in five Chinese indigenous cattle breeds and their association with growth traits

BACKGROUND: Transmembrane protein 95 (TMEM95) plays a role in male fertility. Previous studies showed that genes with a significant impact on reproductive traits can also affect the growth traits of livestock. Thus, we speculated that the genetic variation of TMEM95 gene may have effects on growth traits of cattle. RESULTS: Two SNPs were genotyped. The rs136174626 and rs41904693 were in the intron 4 and 30 -untranslated region, respectively. The linkage disequilibrium analysis illustrated that these two loci were not linked. The rs136174626 was associated with six growth traits of Nanyang cattle, four traits of Luxi cattle, and three traits of Ji'an cattle. For rs41904693 locus, the GG individuals had greater body height and abdominal girth in Ji' an cattle than TT and TG individuals. In Jinnan cattle, GG and TT individuals had greater body height, height at hip cross, body length, and heart girth than TG individuals. The potential splice site prediction results suggest that the rs136174626 may influence the splicing efficiency of TMEM95, and the miRNA binding site prediction results showed that the rs41904693 may influence the expression of TMEM95 by affecting the binding efficiency of Bta-miR-1584 and TMEM95 30 -UTR. CONCLUSIONS: The findings of the study suggested that the two SNPs in TMEM95 could be a reliable basis for molecular breeding in cattle.

Microsurgical anatomy of language.

The localizationist model, which focused on classical cortical areas such as Broca's and Wernicke's, can no longer explain how language processing works. Over recent years, several studies have revealed new language-related cortical and subcortical areas, resulting in a transition from localizationist concepts to a hodotopical model. These studies have described language processing as an extensive and complex network of multiple interconnected cortical areas and subcortical pathways, differing from the classical circuit described by the localizationist perspective. The hodotopical model was made possible by a paradigm shift in the treatment of cerebral tumors, especially low-grade gliomas: total or subtotal tumor resections with cortical and subcortical mapping on awake patients have become the gold standard treatment for lesions located in the dominant hemisphere. In this article, we review current understating of the microsurgical anatomy of language.

Hippocampal vascularization: Proposal for a new classification.

BACKGROUND: Anatomy of the hippocampal arterial supply is key to successful surgeries in this area. The goal of the current study is to present the results we obtained from our microsurgical dissections of the temporal lobe and to propose a new classification for the hippocampal arteries (HAs). METHODS: Fifty-six brain hemispheres were analyzed. All dissections in this study were made using 3-40× at the surgical microscope. RESULTS: The hippocampal arterial vasculature can be divided into six groups, according to their frequencies: Group A: mixed arterial vasculature originating from the anterior choroidal artery anterior choroidal artery, posterior cerebral artery (PCA), anterior infratemporal artery (AIA), and splenic artery (SA). Group B: Main origin at the temporal branches - main inferotemporal trunk, middle inferotemporal artery, posterior inferotemporal artery, AIA, or main branch of PCA. Group C: AIA as the main branch of the hippocampus. Group D: HAs originating from the main branch of PCA. Group E: A single hippocampal artery with the origin at the main branch of PCA. This single artery covered all of the structure and is named Ushimura's artery. Group F: The hippocampal vessels arose exclusively from the parieto-occipital artery, calcarine artery (CA), and the SA. CONCLUSION: This study proposes a new classification for the hippocampal vascularization, according to the origin of HAs. One of the groups has not yet been described in the literature - in which the HAs arise from the parieto-occipital artery, SA, and CA.

Cytotoxic and anti-infective sesquiterpenes present in Plagiochila disticha (Plagiochilaceae) and Ambrosia peruviana (Asteraceae).

A pharmacological screening of the ethanol extract and fractions of two Peruvian medicinal plants, Plagiochila disticha and Ambrosia peruviana, led to the isolation and characterization of three ENT-2,3-secoaromadendrane-type sesquiterpenoids, named plagiochiline A ( 1), I ( 2), and R ( 3), as well as of two pseudoguaianolids, damsin ( 4) and confertin ( 5), which exhibited significant cytotoxic activity against a panel of human tumor cell lines. Compounds 1, 4, and 5 were also investigated for their in vitro antileishmanial, trypanocidal, and antituberculosis activity against Leishmania amazonensis axenic amastigotes and Trypanosoma cruzi trypomastigotes, as well as against MDR and sensitive strains of Mycobacterium tuberculosis, respectively.
