Identifying units of biological diversity is a major goal of organismal biology. An increasing literature has focused on the importance of cryptic diversity, defined as the presence of deeply diverged lineages within a single species. While most discoveries of cryptic lineages proceed on a taxon-by-taxon basis, rapid assessments of biodiversity are needed to inform conservation policy and decision-making. Here, we introduce a predictive framework for phylogeography that allows rapidly identifying cryptic diversity...

There has been a resurgence of interest in aerosolization of antibiotics for treatment of patients with severe pneumonia, caused by multi-drug resistant pathogens. A combination formulation of amikacin/fosfomycin is currently undergoing clinical testing although the exposure response-relationships of these drugs have not been fully characterized. The aim of this study was to describe the individual and combined antibacterial effects of simulated epithelial lining fluid exposures of aerosolized amikacin and fosfomycin against resistant clinical isolates of Pseudomonas aeruginosa (MICs 16 mg/L; 64 mg/L) and Klebsiella pneumoniae (MICs 2 mg/L; 64 mg/L) using the dynamic hollow-fiber infection model over 7-days...

Anthropology has increasingly questioned the hegemony of biomedical knowledge in ethical review processes of social research projects prevailing in Brazil, which was governed until 2012 by the Human Research Ethics Committee of each institution under the auspices of the National Research Ethics Commission (CONEP). This was mandated through Resolution No. 196/1996 prevailing in 2012 when this field research was conducted. The scope of this study is to recount and reflect upon the barriers to obtaining approval in 2012 for my master's research project from the Human Research Ethics Committee of the Federal University of Santa Catarina (CEP/UFSC) in Florianopolis...

The current research explores the idea that self-defeating behaviors represent means toward individuals' goals. In this quality, they may be automatically initiated upon goal activation without individual's voluntary intention and thus exemplify the long-held idea that the end justifies the means. To investigate this notion empirically we explored one of the most problematic self-defeating behavior: engagement in sex exchange for crack cocaine. This behavior is common among female drug users despite its well-known health and legal consequences...

The study examined sexual delay discounting, or the devaluation of condom-protected sex in the face of delay, as a risk factor for sexually transmitted infection (STI) among college students. Participants (143 females, 117 males) completed the sexual delay discounting task (Johnson & Bruner, 2012) and questionnaires of risky sexual behavior, risk perception, and knowledge. Participants exhibited steeper sexual delay discounting (above and beyond general likelihood of having unprotected sex) when partners were viewed as more desirable or less likely to have a STI, with males demonstrating greater sexual delay discounting than females across most conditions...

In many vertebrate cell types, the proximal part of the primary cilium is positioned within an invagination of the plasma membrane known as the ciliary pocket. Recent evidence points to the conclusion that the ciliary pocket comprises a unique site for exocytosis and endocytosis of ciliary proteins, which regulates the spatiotemporal trafficking of receptors into and out of the cilium to control its sensory function. In this chapter, we provide methods based on electron microscopy, 3D reconstruction of fluorescence images as well as live cell imaging suitable for investigating processes associated with endocytosis at the ciliary pocket...

Patients with cervical cancer (CxCa) typically present an infiltrate of tumor-associated macrophages, which is associated with a poor prognosis. We found that CxCa cell lines (HeLa, SiHa, and C-33A) secreted factors involved in regulating tumor growth including IL-6, IL-4, PDGFAA, HGF, VEGF, ANG-2, and TGF-β3. We assessed the effects of culture supernatants from these cell lines on macrophages derived from the THP-1 cell line. Macrophages treated with culture supernatants from CxCa cells developed an M2-like phenotype with expression of CD163, low nitric oxide release, and high secretion of IL-6, PDGFAA, HGF, ANG-2, and VEGF...

Leptospiral infection is widespread in wildlife. In this context, wild ecosystems in tropical countries hold a vast biodiversity, including several species that may act as potential reservoirs of leptospires. The Pantanal biome presents highly favorable environmental conditions for the occurrence of leptospirosis, such as high temperatures, constant flooding, and high biodiversity. The purpose of this study was to detect wild animals as carriers of Leptospira sp. using direct methods (PCR and culture) in the Pantanal biome, Brazil...

Bovine leukemia virus (BLV) infection is widespread mainly in dairy cattle and 5-10% of infected animals will die due to lymphosarcoma; most cattle remain asymptomatic but 30% develop persistent lymphocytosis (PL). BLV transmission depends on infected cell exchange and thus, proviral load is determinant. Understanding the mechanisms which govern the control of viral dissemination will be desirable for the design of effective therapeutic or preventive strategies for BLV. The development of high proviral load (HPL) or low proviral load (LPL) might be associated to genetic factors and humoral immune responses, however cellular responses are not fully described...

Photothermal therapy has shown to be a promising technique for local treatment of tumors. However, the main challenge for this technique is the availability of localized heat sources to minimize thermal damage in the surrounding healthy tissue. In this work, we demonstrate the use of optical fiber microheaters for inducing thermal lesions in soft tissue. The proposed devices incorporate carbon nanotubes or gold nanolayers on the tips of optical fibers for enhanced photothermal effects and heating of ex vivo biological tissues...
