Transmission-blocking vaccines (TBVs) that target sexual stage parasite development could be an integral part of measures for malaria elimination. Pfs25 is a leading TBV candidate, and previous studies conducted in animals demonstrated an improvement of its functional immunogenicity after conjugation to EPA, a recombinant, detoxified ExoProtein A from Pseudomonas aeruginosa. In this report, we describe results of an open-label, dose-escalating Phase 1 trial to assess the safety and immunogenicity of Pfs25-EPA conjugates formulated with Alhydrogel®...

The development of nanomedicines for the treatment of cancer focuses on the local targeted delivery of chemotherapeutic drugs to enhance drug efficacy and reduce adverse effects. The nanomedicines which are currently approved for clinical use are mainly successful in terms of improved bioavailability and tolerability but do not necessarily increase drug performance. Therefore, there is a need for improved drug carrier systems which are able to deliver high doses of anti-cancer drugs to the tumor. Stimuli responsive carriers are promising candidates since drug release can be triggered locally in the tumor via internal (i...

Acquired psychogenic or functional speech disorders are a subtype of functional neurologic disorders. They can mimic organic speech disorders and, although any aspect of speech production can be affected, they manifest most often as dysphonia, stuttering, or prosodic abnormalities. This chapter reviews the prevalence of functional speech disorders, the spectrum of their primary clinical characteristics, and the clues that help distinguish them from organic neurologic diseases affecting the sensorimotor networks involved in speech production...

The clinical importance of blood group antigens relates to their ability to evoke immune antibodies that are capable of causing hemolysis. The most important antigens for safe transfusion are ABO and D (Rh), and typing for these antigens is routinely performed for patients awaiting transfusion, prenatal patients, and blood donors. Typing for other blood group antigens, typically of the Kell, Duffy, Kidd, and MNS blood groups, is sometimes necessary, for patients who have, or are likely to develop antibodies to these antigens...

Clinical errors are common and can lead to adverse events and patient death. Health professionals must work within interprofessional teams to provide safe and effective care to patients, yet current curricula is lacking with regards to interprofessional education and patient safety. We describe the development and implementation of an interprofessional course aimed at medical, nursing, and pharmacy learners during their clinical training at a large academic medical centre. The course objectives were based on core competencies for interprofessional education and patient safety...

Pain is a widespread and debilitating symptom of multiple sclerosis (MS), a chronic inflammatory demyelinating disease of the central nervous system. Although central neuroinflammation and demyelination have been implicated in MS-related pain, the contribution of peripheral and central mechanisms during different phases of the disease remains unclear. In this study, we used the animal model experimental autoimmune encephalomyelitis (EAE) to examine both stimulus-evoked and spontaneous pain behaviors, and neuroinflammatory changes, over the course of chronic disease...

The nature of chemical bonding of molybdenum in high level nuclear waste glasses has been elucidated by ab initio molecular dynamics simulations. Two compositions, (SiO2)57.5-(B2O3)10-(Na2O)15-(CaO)15-(MoO3)2.5 and (SiO2)57.3-(B2O3)20-(Na2O)6.8-(Li2O)13.4-(MoO3)2.5, were considered in order to investigate the effect of ionic and covalent components on the glass structure and the formation of the crystallisation precursors (Na2MoO4 and CaMoO4). The coordination environments of Mo cations and the corresponding bond lengths calculated from our model are in excellent agreement with experimental observations...

Discovery and validation of genetic variants that influence disease severity in children with sickle cell anemia (SCA) could lead to early identification of high-risk patients, better screening strategies, and intervention with targeted and preventive therapy. We hypothesized that newly identified genetic risk factors for the general African American population could also impact laboratory biomarkers known to contribute to the clinical disease expression of SCA, including variants influencing the white blood cell count and the development of albuminuria and abnormal glomerular filtration rate...

Transcription factor EKLF (Erythroid Krüppel-Like Factor) belongs to the group of Krüppellike factors, which regulate proliferation, differentiation, development and apoptosis of mammalian cells. EKLF factor is present in erythroid cells, where it participates in regulation of hematopoiesis, expression of genes encoding transmembrane proteins (including blood group antigens), and heme biosynthesis enzymes. It is also a key factor in downregulation of γ-globins and activation of β-globin gene expression...

Pigs (Sus scrofa) have played an important cultural role in Hawaii since Polynesians first introduced them in approximately AD 1200. Additional varieties of pigs were introduced following Captain Cook's arrival in Hawaii in 1778 and it has been suggested that the current pig population may descend primarily, or even exclusively, from European pigs. Although populations of feral pigs today are an important source of recreational hunting on all of the major islands, they also negatively impact native plants and animals...

The occurrence of the sandbar shark Carcharhinus plumbeus at Norfolk Island is confirmed. Carcharhinus plumbeus occurs over the mid to outer insular shelf from 38 m to at least 53 m depth, and appears to be at least as abundant as C. galapagensis in this habitat. No C. plumbeus were caught from shore despite most fishing effort being land-based. The presence of young-of-the-year confirms C. plumbeus breeds on the Norfolk Island shelf. Size at birth and the timing of parturition appear similar to that reported for eastern Australia...

Genetic variability in Plasmodium falciparum malaria parasites hampers current malaria vaccine development efforts. Here, we hypothesize that to address the impact of genetic variability on vaccine efficacy in clinical trials, conserved antigen targets should be selected to achieve robust host immunity across multiple falciparum strains. Therefore, suitable vaccine antigens should be assessed for levels of polymorphism and genetic diversity. Using a total of one hundred and two clinical isolates from a region of high malaria transmission in Uganda, we analyzed extent of polymorphism and genetic diversity in four recently reported novel blood-stage malaria vaccine candidate proteins: Rh5 interacting protein (PfRipr), GPI anchored micronemal antigen (PfGAMA), rhoptry-associated leucine zipper-like protein 1 (PfRALP1) and Duffy binding-like merozoite surface protein 1 (PfMSPDBL1)...

Lung transplant recipients (LTR) are at high risk of cutaneous squamous cell carcinoma (SCC). Voriconazole exposure after lung transplant has recently been reported as a risk factor for SCC. We sought to study the relationship between fungal prophylaxis with voriconazole and the risk of SCC in sequential cohorts from a single center. We evaluated 400 adult LTR at UCLA between 7/1/2005 and 12/22/2012. On 7/1/2009 our center instituted a protocol switch from targeted to universal antifungal prophylaxis for at least 6 months post-transplant...

BACKGROUND: In the US familial hypercholesterolemia (FH), patients are underidentified, despite an estimated prevalence of 1:200 to 1:500. Criteria to identify FH patients include Simon Broome, Dutch Lipid Clinic Network (DLCN), or Make Early Diagnosis to Prevent Early Deaths (MEDPED). The use of these criteria in US clinical practices remains unclear. OBJECTIVE: To characterize the FH diagnostic criteria applied by US lipid specialists participating in the FH Foundation's CASCADE FH (CAscade SCreening for Awareness and DEtection of Familial Hypercholesterolemia) patient registry...

In vitro activities of omadacycline, a new aminomethylcycline, were determined for Mycoplasma and Ureaplasma spp. in comparison to azithromycin, clindamycin, moxifloxacin, tetracycline, and doxycycline. All omadacycline MICs were < 2 μg/ml. MIC90s were 0.063 μg/ml for Mycoplasma hominis, 0.25 μg/ml for Mycoplasma pneumoniae, and 2 μg/ml for Ureaplasma spp. Omadacycline had the lowest MIC90 among all drugs tested against M. hominis Omadacycline activity was not affected by macrolide, tetracycline, or fluoroquinolone resistance...
