Clinical Pharmacist Services on Admission to a Large Correctional Center.

The clinical role of pharmacists in a correctional facility has not been fully described. We report the proportion of patients assessed by a pharmacist within 48 hours of admission to a large correctional facility. Of those assessed, the frequency and type of pharmacist interventions were described. A retrospective chart review was conducted for patients admitted to the Edmonton Remand Center (ERC) from September to November 2017. From 1,500 patients, 518 (34.5%) were assessed by a pharmacist, and 511 (98.6%) of those received one or more pharmacist interventions. Interventions were most commonly health care provider interactions (89.0%) and drug therapy interventions (76.1%). ERC pharmacists assessed a sizable proportion of admitted patients, with most receiving at least one pharmacist intervention.

Graphene nanoplatelet-induced strengthening of ultrahigh molecular weight polyethylene and biocompatibility in vitro.

Graphene nanoplatelets (GNPs) are added as reinforcement to ultrahigh molecular weight polyethylene (UHMWPE) with an intended application for orthopedic implants. Electrostatic spraying is established as a potential fabrication method for synthesizing large-scale UHMWPE-GNP composite films. At a low concentration of 0.1 wt % GNP, the composite film shows highest improvement in fracture toughness (54%) and tensile strength (71%) as compared to UHMWPE. Increased GNP content of 1 wt % leads to improvement in elastic modulus and yield strength but fracture toughness and tensile strength are reduced significantly at higher GNP content. The strengthening mechanisms of the UHMWPE-GNP system are highly influenced by the GNP concentration, which dictates its degree of dispersion and extent of polymer wrapping. The fraction of GNPs oriented along the tensile axis influences the elastic deformation, whereas the wrapping of polymer and GNP-polymer interfacial strength determines the deformation behavior in the plastic regime. The cytotoxicity of GNP to osteoblast is dependent on its concentration and is also influenced by agglomeration of particles. Lowering the concentration of GNPs in UHMWPE improves the biocompatibility of the composite surface to bone cells. The survivability of osteoblasts deteriorates up to 86% on 1 wt % GNP containing surface, whereas much smaller (6-16%) reduction is observed for 0.1 wt % GNP over 5 days of incubation.

Pre: Surgical orthopedic pre-maxillary alignment in bilateral cleft lip and palate patient.

Pre-surgical orthopedic appliances are mainly used to retract and align the protruded and deviated pre-maxilla and to facilitate initial lip repair. This article presents a case report of a five year old male child patient with bilateral cleft lip and palate in whom a special custom made pre-surgical orthopedic appliance was delivered. Use of a special custom made presurgical orthopedic appliance for repositioning pre-maxilla in bilateral cleft lip and palate patient is discussed in this article.

Genetic transformation of Neurospora tetrasperma, demonstration of repeat-induced point mutation (RIP) in self-crosses and a screen for recessive RIP-defective mutants.

The pseudohomothallic fungus Neurospora tetrasperma is naturally resistant to the antibiotic hygromycin. We discovered that mutation of its erg-3 (sterol C-14 reductase) gene confers a hygromycin-sensitive phenotype that can be used to select transformants on hygromycin medium by complementation with the N. crassa erg-3+ and bacterial hph genes. Cotransformation of hph with PCR-amplified DNA of other genes enabled us to construct strains duplicated for the amplified DNA. Using transformation we constructed self-fertile strains that were homoallelic for an ectopic erg-3+ transgene and a mutant erg-3 allele at the endogenous locus. Self-crosses of these strains yielded erg-3 mutant ascospores that produced colonies with the characteristic morphology on Vogel's sorbose agar described previously for erg-3 mutants of N. crassa. The mutants were generated by repeat-induced point mutation (RIP), a genome defense process that causes numerous G:C to A:T mutations in duplicated DNA sequences. Homozygosity for novel recessive RIP-deficient mutations was signaled by self-crosses of erg-3-duplication strains that fail to produce erg-3 mutant progeny. Using this assay we isolated a UV-induced mutant with a putative partial RIP defect. RIP-induced mutants were isolated in rid-1 and sad-1, which are essential genes, respectively, for RIP and another genome defense mechanism called meiotic silencing by unpaired DNA.

Genetic analysis of wild-isolated Neurospora crassa strains identified as dominant suppressors of repeat-induced point mutation.

Repeat-induced point mutation (RIP) in Neurospora results in inactivation of duplicated DNA sequences. RIP is thought to provide protection against foreign elements such as retrotransposons, only one of which has been found in N. crassa. To examine the role of RIP in nature, we have examined seven N. crassa strains, identified among 446 wild isolates scored for dominant suppression of RIP. The test system involved a small duplication that targets RIP to the easily scorable gene erg-3. We previously showed that RIP in a small duplication is suppressed if another, larger duplication is present in the cross, as expected if the large duplication competes for the RIP machinery. In two of the strains, RIP suppression was associated with a barren phenotype--a characteristic of Neurospora duplications that is thought to result in part from a gene-silencing process called meiotic silencing by unpaired DNA (MSUD). A suppressor of MSUD (Sad-1) was shown not to prevent known large duplications from impairing RIP. Single-gene duplications also can be barren but are too short to suppress RIP. RIP suppression in strains that were not barren showed inheritance that was either simple Mendelian or complex. Adding copies of the LINE-like retrotransposon Tad did not affect RIP efficiency.
