Abstract Introduction Anterior cruciate ligament (ACL) reconstruction is the most performed orthopedic surgical procedure. The result of ACL reconstructions depends on multiple technical variables, including tension to be applied to the graft for fixation, knee-flexion angle during fixation and the type of fixation to the bone. Objective To carry out a survey of the literature with the best evidence on these themes. Methods Literature review about methods of tibial-graft fixation in ACL reconstructions – ...

Materiais mesoporosos tipo SBA-15 e MCM-48 foram sintetizados com sucesso pelo método hidrotérmico e impregnados com níquel nas proporções de 5-20 peso% visando à captura de CO2. Os materiais obtidos foram caracterizados por meio de análise por difração de raios X, adsorção de N2 e microscopia eletrônica de varredura. Testes de captura de CO2 foram conduzidos em pressões entre 100 e 4000 KPa à temperatura constante de 298 K e revelaram que as capacidades de adsorção variam significativamente com ...

Tregidgo et al. (1) show that size-selective overfishing has drastically depleted and downsized populations of tambaqui ( Colossoma macropomum ) along the Purus River, Amazonia. Because fishers have historically targeted the largest individuals, tambaqui ∼1,000 km upriver are twofold larger than those near the Manaus rainforest metropolis (1). Here, we demonstrate that this overfishing shadow has cascading consequences, reaching beyond the sustainability of this fishery. By effectively dispersing seeds ...

Abstract This study aimed to investigate the relationship between genetic ancestry inferred from autosomal and Y chromosome markers and HLA genotypes in patients with Type 1 Diabetes from an admixed Brazilian population. Inference of autosomal ancestry; HLA-DRB1 , -DQA1 and -DQB1 typifications; and Y chromosome analysis were performed. European autosomal ancestry was about 50%, followed by approximately 25% of African and Native American. The European Y chromosome was predominant. The HLA-DRB1*03 and ...

The development of products and processes which are more ecological has been a source of interest in research in recent decades. Thus, researchers have developed several methods to improve the synthesis of oxides and metals in a more ecological way. Green synthesis has become a method that is being widely used for presenting low temperature, low cost and great availability of raw material. Some biological sources such as fungi, bacteria and plants are used in this route, but plant extracts are the ...

Type 1 diabetes (T1D) is a chronic disease characterized by the immune-mediated destruction of the pancreatic beta cells responsible for insulin production. The secreted insulin and C-peptide are equimolar. Due to its longer half-life, C-peptide has become a safer means of assessing the pancreatic reserve. C-peptide levels were evaluated in a population of patients with T1D, focusing on the relationship between this variable and other factors. In addition, the influence of C-peptide on metabolic ...
