38. Sarcopenia predicts prognosis of patients with renal cell carcinoma: A systematic review and meta-analysis
ABSTRACT Sarcopenia, a concept reflecting the loss of skeletal muscle mass, was reported to be associated with the prognosis of several tumors. However, the prognostic value of sarcopenia in patients with renal cancer remains unclear. We carried out this metaanalysis and systematic review to evaluate the prognostic value of sarcopenia in patients with renal

40. Immunohistochemical analysis of S100-positive epidermal Langerhans cells in dermatofibroma,
Abstract Dermatofibroma is a dermal fibrohistiocytic neoplasm. The Langerhans cells are the immunocompetent cells of the epidermis, and they represent the first defense barrier of the immune system towards the environment. The objective was to immunohistologically compare the densities of S100-positive Langerhans cells in the healthy peritumoral epidermis ag

41. Analysis of the Gene Expression and RNAi-Mediated Knockdown of Chitin Synthase from Leaf-Cutting Ant Atta sexdens
Chitin synthase (CHS) is the enzyme specifically associated with chitin synthesis, an important component of diverse organisms including insects. Two alternative spliced transcripts of the CHS gene (AsCHS-A1 and AsCHS-A2) were identified by quantitative reverse-transcription polymerase chain reaction (RT-qPCR) during the development of the leaf-cutting ant A

42. Cross-cultural adaptation of the Internet Gaming Disorder Scale – Short Form (IGDS9-SF) to the Brazilian context
Abstract Introduction The Internet Gaming Disorder Scale – Short Form (IGDS9-SF) assesses the severity, harmful effects and/or consequences of excessive online and offline gaming. Its conciseness and theoretical foundations on current diagnostic criteria of gaming disorders make it a useful resource for clinical and screening settings. Objective To descr

43. Fast Verification of Buffalo’s Milk Authenticity by Mid-Infrared Spectroscopy, Analytical Measurements and Multivariate Calibration
Mid-infrared spectroscopy (MID), chemical composition and physicochemical characteristics associated with chemometrics were used to rapidly detect and quantify the amount of cow’s milk added in buffalo’s milk. A total of 165 samples, divided into buffalo’s milk, buffalo’s milk added with cow’s milk (10 to 90%) and cow’s milk were evaluated to obt

44. Cost minimization analysis of an in-house molecular test for cytomegalovirus in relation to a commercial molecular system
ABSTRACT Introduction: Cytomegalovirus may cause severe disease in immunocompromised patients. Nowadays, quantitative polymerase chain reaction is the gold-standard for both diagnosis and monitoring of cytomegalovirus infection. Most of these assays use cytomegalovirus automated molecular kits which are expensive and therefore not an option for small labora

47. In vitro anti-aging activities of ginkgo biloba leaf extract and its chemical constituents
Abstract To determine in vitro anti-aging activity and identify the active chemical constituents in Ginkgo leaf extracts. The antioxidant properties of Ginkgo biloba leaves extracts were evaluated using 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging and 2,2’-azino-bis (3-ethylbenzothiazoline)-6 sulfonic acid radical (ABTS) scavenging assays. The i

48. Quantification of mitochondrial DNA damage and copy number in circulating blood of patients with systemic sclerosis by a qPCR-based assay,
Abstract Background: Although not fully understood, oxidative stress has been implicated in the pathogenesis of different autoimmune diseases such as systemic sclerosis. Accumulating evidence indicates that oxidative stress can induce mitochondrial DNA (mtDNA) damage and variations in mtDNA copy number (mtDNAcn). Objective: The aim of this study was to exp
