Multifunctional liposomes (mf-LIPs) having a curcumin-lipid ligand (to target amyloids) together with two ligands to target the transferrin, and the low-density apolipoprotein receptor of the blood-brain-barrier (BBB) on their surface, were previously studied (in vitro) as potential theranostic systems for Alzheimer's disease (AD) (Papadia et al., 2017, Eur. J. Pharm. Sciences; 101:140-148). Herein, the targeting potential of mf-LIPs was compared to that of BBB-LIPs (liposomes having only the two BBB-specific ligands) in FVB mice (normal), as well as in double transgenic mice (APP/PS1) and their corresponding littermates (WT), by live-animal (in vivo) and explanted organ (ex vivo) imaging...

Lactoferrin and lysozyme are 2 glycoproteins with great antimicrobial activity, being part of the nonspecific defensive system of human milk, though their use in commercial products is difficult because human milk is a limited source. Therefore, many investigations have been carried out to produce those proteins in biological systems, such as bacteria, yeasts, or plants. Mammals seem to be more suitable as expression systems for human proteins, however, especially for those that are glycosylated. In the present study, we developed a bicistronic commercial vector containing a goat β-casein promoter and an internal ribosome entry site fragment between the human lactoferrin and human lysozyme genes to allow the introduction of both genes into bovine adult fibroblasts in a single transfection...

BACKGROUND: Studies evaluating the relationship between soluble transferrin receptor (sTfR), a biomarker inversely related to body iron stores, and risk of type 2 diabetes mellitus (T2DM) are scarce and inconclusive. Furthermore, sTfR concentrations have been observed to be significantly higher in obese than in nonobese individuals. Therefore, the aim of this study was to assess the relationship between sTfR and the risk of T2DM in obese and nonobese subjects. DESIGN: A nested case-control study of 153 cases of newly diagnosed diabetic subjects, 73 obese and 80 nonobese, and 306 individually matched controls, 138 obese and 166 nonobese, who did not develop T2DM for a median 6-year follow-up (interquartile range: 3·9-6·5) was conducted using data from the PREvention with MEDiterranean Diet (PREDIMED) cohort (http://www...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and increases risk of stroke by nearly 5-fold. While warfarin has been employed successfully to reduce the risk of stroke in these patients, there are a number of challenges with therapy. These include the need for therapeutic monitoring due to variability in patient response, frequent dose adjustments, numerous drug-drug, drug-food, and drug-disease interactions, and a heightened risk of thrombosis and bleeding due to these issues. Current guidelines recommend that the vitamin K antagonists (VKA) or direct oral anticoagulants (DOACs) should be used for thromboprophylaxis in patients with nonvalvular AF at risk for stroke or systemic embolic events...

Regardless of practice setting, it is imperative that pharmacists be able to either participate in generating new knowledge or use the ever-expanding body of literature to guide patient care. However, competing priorities in Pharm.D. curricula and residency training programs have resulted in limited emphasis on acquiring research and scholarly skills. Factors likely contributing to this reduced focus include the lack of curricular and postgraduate training standards emphasizing the development of research skills, time to commit to scholarly activity, and accessibility to experienced mentors...

BACKGROUND: Genome-wide gene expression profiling of mammalian cells is becoming a staple of many published biomedical and biological research studies. Such data is deposited into data repositories such as the Gene Expression Omnibus (GEO) for potential reuse. However, these repositories currently do not provide simple interfaces to systematically analyze collections of related studies. RESULTS: Here we present GENE Expression and Enrichment Vector Analyzer (GEN3VA), a web-based system that enables the integrative analysis of aggregated collections of tagged gene expression signatures identified and extracted from GEO...

Genomics, epigenomics, transcriptomics, proteomics and metabolomics efforts rapidly generate a plethora of data on the activity and levels of biomolecules within mammalian cells. At the same time, curation projects that organize knowledge from the biomedical literature into online databases are expanding. Hence, there is a wealth of information about genes, proteins and their associations, with an urgent need for data integration to achieve better knowledge extraction and data reuse. For this purpose, we developed the Harmonizome: a collection of processed datasets gathered to serve and mine knowledge about genes and proteins from over 70 major online resources...

BACKGROUND: Pharmacists and health care professionals are faced with increasing and changing health care needs around the world. To meet these demands, they are required to continuously upgrade and develop their professions. Reprofessionalization is therefore crucial to the successful delivery of health services, but traditional theories might provide little practical guidance to evaluating the overall status of a profession. OBJECTIVE: This study proposes a new conceptual framework of three interrelated professional sectors: education, regulation and practice, and uses it to identify and analyze challenges facing the pharmacy profession in Jordan...

Burst release was observed when ethylene vinyl acetate copolymer (EVA) intravaginal rings were tested for progesterone release in our previous work (Helbling et al. Pharm Res. 31(3):795-808, 2014). Burst release is undesirable in controlled delivery devices because release is uncontrollable and higher levels of active pharmaceutical ingredient could lead to the occurrence of adverse effect. The present contribution is about the use of membranes to coat EVA rings to eliminate burst release. Physicochemical state of progesterone in uncoated rings and the solubility and diffusion coefficient in membrane were studied...

Diarrhea caused by Shigella, Salmonella, and Yersinia is an important public health problem, but development of safe and effective vaccines against such diseases is challenging. A new antigen delivery platform called bacterium-like particles (BLPs) was explored as a means for delivering protective antigens from the type III secretion systems (T3SS) of these pathogens. BLPs are peptidoglycan skeletons derived from Lactococcus lactis that are safe for newborns and can carry multiple antigens. Hydrophobic T3SS translocator proteins were fused to a peptidoglycan anchor (PA) for BLP attachment...

This study was designed to assess the effects of cooling rate, storage temperature, and formulation composition on trehalose phase distribution and protein stability in frozen solutions. The data demonstrate that faster cooling rates (>100°C/min) result in trehalose crystallization and protein aggregation as determined by Fourier Transform Near-Infrared (FT-NIR) spectroscopy and size-exclusion chromatography, respectively. Conversely, at slower cooling rates (≤1°C/min), trehalose remains predominantly amorphous and there is no effect on protein stability...
