Porous scaffold biomaterials may offer a clinical alternative to bone grafts; however, scaffolds alone are typically insufficient to heal large bone defects. Numerous studies have demonstrated that osteoinductive growth factor significantly improves bone repair. In this study, a strategy combining degradable bioactive borate glass (BG) scaffolds with platelet-rich plasma (PRP) was tested. The b...

BACKGROUND Breast cancer risk education enables women make informed decisions regarding their options for screening and risk reduction. We aimed to determine whether patient education regarding breast cancer risk using a bar graph, with or without a frequency format diagram, improved the accuracy of risk perception. METHODS We conducted a prospective, randomized trial among women at increased...

Most of our motor skills are not innately programmed, but are learned by a combination of motor exploration and performance evaluation, suggesting that they proceed through a reinforcement learning (RL) mechanism. Songbirds have emerged as a model system to study how a complex behavioral sequence can be learned through an RL-like strategy. Interestingly, like motor sequence learning in mammals,...

The notation and terminology used here have been introduced in the following papers: [1], [2], [4], [3], and [5]. For simplicity, we use the following convention: Y is a non empty set, a is an element of BVF(Y ), G is a subset of PARTITIONS(Y ), and A, B, C, D are partitions of Y . Next we state a number of propositions: (1) If G is a coordinate and G = {A,B, C,D} and A 6= B and A 6= C and A 6=...

OBJECTIVE To determine whether an educational intervention for medical house staff improves blood glucose (BG) in hospitalized patients. RESEARCH DESIGN AND METHODS All 116 medicine residents at an academic medical center were assigned to online or classroom training on inpatient dysglycemia in fall 2008. Both groups were offered an online refresher course in spring 2009 addressing gaps in cl...

Folding of the cortex and the persistence of radial glia (RG)-like cells called Bergmann glia (BG) are hallmarks of the mammalian cerebellum. Similar to basal RG in the embryonic neocortex, BG maintain only basal processes and continuously express neural stem cell markers. Past studies had focused on the function of BG in granule cell migration and how granule cell progenitors (GCP) regulate ce...

Background: Compact cyclotrons are getting popular to fulfill enormous current demands of PET tracers. Aga Khan University Hospital, Karachi, Pakistan has acquired the first smallest footprint of BG-75 Generator for 18FDG-based PET/CT clinical imaging. We are sharing our experience of BG-75 in the first year (December 2015-November 2016) after commissioning. Mater...

Background and Aim: Most dentists rely on the patient's history when assessing a patient's medical status although many patients are unaware of their medical condition. We aimed to evaluate patients' knowledge of their blood pressure (BP) and blood glucose (BG) at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2018. Materials and Methods: In this cross-sect...

Two commercially available Bifidobacterium spp. (Bifidobacterium infantis and Bifidobacterium lactis) were compared for their capacities to protect immunodeficient bg/bg-nu/nuand bg/bg-nu/+mice from orogastric and lethal candidiasis. Both Bifidobacterium spp. prolonged the survival of Candida albicans-colonized adult and neonatal bg/bg-nu/numice. The bifidobacteria affected the production of an...

Polymer scaffold systems consisting of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) have proven to be possible matrices for the three-dimensional growth of chondrocyte cultures. However, the engineered cartilage grown on these PHBV scaffolds is currently unsatisfactory for clinical applications due to PHBV's poor hydrophilicity, resulting in inadequate thickness and poor biomechanical proper...
