Background/aims: To assess the technical feasibility and outcomes of femtosecond laser-assisted Bowman layer transplantation (FLABOLT) in stabilizing progressive, advanced keratoconus, which is ineligible for corneal crosslinking.
Methods: This single-center retrospective study included 50 eyes of 49 patients with progressive advanced keratoconus, ineligible for corneal crosslinking, that underwent FLABOLT with both the donor graft and recipient mid-stromal pocket using a femtosecond laser.
Results: The mean follow-up was 13.
Background: Remote ischemic perconditioning (rPER) is the newest technique described to mitigate ischemia and reperfusion (IR) injury. Local postconditioning (POS) is also an effective technique for this purpose. It is uncertain if adding local POS to rPER provides superior liver protection, so we tested this hypothesis.

Method: 32 male Wistar rats were randomly assigned into four groups: control group (1), total splenectomy group (2), splenectomy and implantation of allograft group (3) and double spleen group (4). Each group was subdivided into two subgroups: A and B, based on the death of the animals after 30 or 120 days of monitoring.
Purpose: To describe a new model to passive smoking for rodents.
Methods: Twenty rats were distributed into two study groups (N=10): control group (CG), that was not exposed to tobacco smoke and used as normal standard for biochemical and histological analysis; Experimental Group (EG), that Animals were exposed to the passive smoking; Euthanasia was performed after 14 days of exposure. The serum level of nicotine and histological analysis were performed.
Objective: To evaluate the influence of the understanding of brain death in relation to organ donation in patients from the Marco School Health Center, which is linked to the Universidade do Estado do Pará.
Methods: A total of 136 patients were interviewed based on a research protocol. The interview results were subsequently analyzed with regard to the understanding of brain death and organ donation in addition to the collection of sociodemographic data.
Objective: Verify whether a journal's impact factor is a mechanism that modifies the ethical requirements described in the instructions provided to authors of articles published in Brazilian medical journals.
Methods: 48 selected journals were divided into two groups: impact-factor (n=24), and no-impact-factor (n=24). The number of ethical requirements was compared between both groups based on a specific research protocol, ranging from zero to six points, analyzing the presence of an approval by a research ethics committee; reference to the fact that the research follows the precepts of the Declaration of Helsinki and the rules of Resolution 196/96; use of an informed consent; information about the authors' conflicts of interest; and a request for registration of clinical trials in the Brazilian Clinical Trials Registry.
Objective: To evaluate the protective effect of remote ischemic per-conditioning in ischemia and reperfusion-induced renal injury.
Methods: Fifteen rats (Rattus norvegicus) were randomized into three groups (n = 5): Group Normality (GN), Control Ischemia and Reperfusion (GIR) and Group remote ischemic per-conditioning (GPER). With the exception of the GN group, all others underwent renal ischemia for 30 minutes.
Purpose: To evaluate the key words used in Acta Cirurgica Brasileira from 1997 to 2012.
Methods: All the key words of all articles published in regular issues between 1997 and 2012 were analyzed, ensuring that these key words were in the MeSH database (Medical Subjects Headings) and the most used subject headings and most wrong repeated key words were ranked.
Results: > 4230 key words used in 990 articles were analyzed.
