#1
Fermin Roland Schramm
Bioethics of protection (BP) was proposed in the early 21st century in bioethics, built in Latin America following attempts by researchers to work on the possibilities of public health policies being morally legitimate, socially fair (equitable) and respectful of human rights, after noting the limits of traditional bioethical tools, essentially implemented in and restricted to interpersonal conflicts between moral agents and patients involved in the practice of biomedicine. Methodologically, BP tries to negotiate distinct problematic disciplinary realms that are, however, interlinked through interdisciplinary dialogue and common concern with the quality of life of the human population, considered in its natural, technological, social and cultural contexts: Public Health, concerned with the health and well-being of individuals and populations; Bioethics, concerned primarily with the moral legitimacy of practices that affect their quality of life; Biopolitics, concerned with the social effects of health policies...

OBJECTIVE: Law powerfully influences health and can be a critical tool for promoting population well-being. Evaluation research is needed to measure the health effects of law and guide policy making and implementation. The purpose of this study was to assess trends in National Institutes of Health (NIH) funding for scientific public health law research (PHLR). METHODS: Using data from the UberResearch NIH grant repository, we collected and coded all grants with a focus on health law between FY'85 and FY'14 and then analyzed the grants by funding agency and topic areas...

PURPOSE: Vascular inflammation and leakage in sepsis is mediated by Angiopoietin-1 (Ang-1) and -2 (Ang-2) and their phosphorylation of the endothelial Tie-2 receptor. Levels of Ang-2 change in adults and children during sepsis, which is associated with severity of sepsis. This study investigates levels of Ang-1 and Ang-2 in newborns to gain insight in the vascular pathophysiology of early onset sepsis (EOS) within 72 hours after birth. METHODS: A prospective cohort study was performed amongst 71 Surinamese newborns treated with antibiotics for suspected EOS and 20 control newborns...

Hypoxia is a common intrauterine stressor, often resulting in intrauterine growth restriction and increased risk for cardiovascular disease later in life. The aim of this work was to test the hypothesis that microRNA-210 (miR-210) mediates the detrimental suppression of glucocorticoid receptor (GR) in response to hypoxia in fetal rat cardiomyocytes. Cardiomyocytes isolated from gestational day 21 Sprague Dawley fetal rats showed increased miR-210 levels and reduced GR abundance after exposure to ex vivo hypoxia (1% O2)...

Bone morphogenetic protein-4 (BMP-4) is considered to have therapeutic potential for various diseases including cancers; however, the high expression of biologically active recombinant human BMP-4 (rhBMP-4) needed to manufacture rhBMP-4 for therapeutic purposes has yet to be established. In the current study, we established a recombinant Chinese hamster ovary (rCHO) cell line overexpressing rhBMP-4 as well as a production process using 7.5-l bioreactor (5 l working volume). The expression of the mature rhBMP-4 was significantly enhanced by recombinant furin expression...

Purpose of the Study: Capacity to manage finances and make financial decisions can affect risk for financial exploitation and is often the basis for legal determinations of conservatorship/guardianship. Several structured assessments of financial capacity have been developed, but have not been compared regarding their focus, validity, or reliability. Therefore, we conducted a review of financial capacity measures to examine these factors. Design and Methods: We searched electronic databases, reference lists in identified articles, conference proceedings and other grey literature for measures of financial capacity...

BACKGROUND: Yarrowia lipolytica, one of the most widely studied "nonconventional" oleaginous yeast species, is unable to grow on cellulose. Recently, we identified and overexpressed two endogenous β-glucosidases in Y. lipolytica, thus enabling this yeast to use cello-oligosaccharides as a carbon source for growth. Using this engineered yeast platform, we have now gone further toward building a fully cellulolytic Y. lipolytica for use in consolidated bioprocessing of cellulose. RESULTS: Initially, different essential enzyme components of a cellulase cocktail (i...

Hydrogels derived from adipose tissue extracellular matrix (AdECM) have shown potential in the ability to generate new adipose tissue in vivo. To further enhance adipogenesis, a composite adipose derived delivery system (CADDS) containing single- and double-walled dexamethasone encapsulated microspheres (SW and DW Dex MS) has been developed. Previously, our laboratory has published the use of Dex MS as an additive to enhance adipogenesis and angiogenesis in adipose tissue grafts. In the current work, AdECM and CADDS are extensively characterized, in addition to conducting in vitro cell culture analysis...

Hepatoma-derived growth factor (HDGF) is present in the endometrium of cows and other mammals. Recombinant HDGF (rHDGF) improves bovine blastocyst development in vitro. However, specific culture conditions and essential aspects of HDGF uterine physiology are yet unknown. In this work we quantified total HDGF protein in uterine fluid (UF) by multiple reaction monitoring (MRM), and analyzed effects of rHDGF on specific embryonic stages with Day-6 bovine embryos cultured in vitro with and without BSA, and on pregnancy viability and calf phenotypes after embryo transfer to recipients...

BACKGROUND: Access to adequate antenatal care (ANC) is critical in ensuring a good maternal health and in preventing maternal and neonatal morbidity and mortality. South Sudan has one of the world's poorest health indicators due to a fragile health system and a combination of socio-cultural, economic, and political factors. This study was conducted to identify barriers to utilisation of ANC services in Rumbek North County. METHODS: Using a qualitative design, data were collected through 14 focus group discussions with 169 women and 45 men and 12 key informant interviews with community leaders, staff working in health facilities, and the staff of the County Health Department...

The cultural turn in critical suicidology notes the limitations of dominant acontextual, biomedical, quantitative approaches to suicide prevention. Qualitative methods are idealized within this cultural turn as the only way to advance suicidology. Qualitative methods, however, also have limitations. Drawing on our research with traditional healers in South Africa, we explore tensions associated with making truth claims based on qualitative research. Turning the critical gaze on our work we consider the question of what we can claim to know about suicide prevention when investigating culture using qualitative methods...

The current standard protocols for characterizing the optogenetic circuit of bacterial cells using flow cytometry in light tubes and light exposure of culture plates are tedious, labor-intensive, and cumbersome. In this work, we engineer a bioreactor with working volume of ~10 mL for in vivo real-time optogenetic characterization of E. coli with a CcaS-CcaR light-sensing system. In the bioreactor, optical density measurements, reporter protein fluorescence detection, and light input stimuli are provided by four light-emitting diode sources and two photodetectors...

Regenerative medicine is taking great advantage from the use of biomaterials in the treatments of a wide range of diseases and injuries. Among other biomaterials, self-assembling peptides are appealing systems due to their ability to spontaneously form nanostructured hydrogels that can be directly injected into lesions. Indeed, self-assembling peptide scaffolds are expected to behave as biomimetic matrices able to surround cells, to promote specific interactions, and to control and modify cell behavior by mimicking the native environment as well...

In this work, a biomimetic synthesis reaction for the production of hydroxyapatite (HA)/natural rubber (NR) composites is presented. HA was synthesized in the presence of solubilized NR in tetrahydrofuran (THF), which permits that negatively charged domains in proteins and lipids in NR work as nucleation sites for hydroxyapatite. The mechanical and physicochemical properties of composites containing 10, 20 and 30wt% HA were studied. NR influenced HA crystallite morphology, shape and size and was able to disperse the HA particles in THF...
