Tricyclic Antidepressant Overdose Manikin Simulation in Student Pharmacists.

Pharmacists must be knowledgeable of medication use within the scope of both typical dosing and atypical dosing. In the United States, antidepressants are the fourth most common substance in overdose situations and are ranked first for serious exposures per year. The purpose of this study is to design, implement, and assess the efficacy of an antidepressant overdose simulation using a high-fidelity manikin.

Beyond the Classroom: An Observational Study to Assess Student Pharmacists' Confidence and Perception of a High-Fidelity Manikin Chemotherapy Infusion Reaction Simulation.

To assess the impact of a high-fidelity manikin chemotherapy infusion simulation on student pharmacists' confidence in applying clinical knowledge and perception of oncology pharmacy practice. One cohort of third professional year student pharmacists completed a high-fidelity manikin simulation during the last week of their didactic training. The 10-minute manikin experience simulated an acute paclitaxel infusion reaction, requiring students to apply their knowledge on how to provide patient care during a chemotherapy-induced infusion reaction.

Urine Single-Cell RNA Sequencing in Focal Segmental Glomerulosclerosis Reveals Inflammatory Signatures.

Introduction: Individuals with focal segmental glomerular sclerosis (FSGS) typically undergo kidney biopsy only once, which limits the ability to characterize kidney cell gene expression over time.

Methods: We used single-cell RNA sequencing (scRNA-seq) to explore disease-related molecular signatures in urine cells from subjects with FSGS. We collected 17 urine samples from 12 FSGS subjects and captured these as 23 urine cell samples.

The tumor specificity of JAA-F11, a novel monoclonal antibody specific for the Thomsen-Friedenreich cancer antigen (TF-Ag-alpha linked), has been comprehensively studied by in vitro immunohistochemical (IHC) staining of human tumor and normal tissue microarrays and in vivo biodistribution and imaging by micro-positron emission tomography imaging in breast and lung tumor models in mice. The IHC analysis detailed herein is the comprehensive biological analysis of the tumor specificity of JAA-F11 antibody performed as JAA-F11 is progressing towards preclinical safety testing and clinical trials. Wide tumor reactivity of JAA-F11, relative to the matched mouse IgG (control), was observed in 85% of 1269 cases of breast, lung, prostate, colon, bladder, and ovarian cancer.

Humanization of JAA-F11, a Highly Specific Anti-Thomsen-Friedenreich Pancarcinoma Antibody and InVitro Efficacy Analysis.

JAA-F11 is a highly specific mouse monoclonal to the Thomsen-Friedenreich Antigen (TF-Ag) which is an alpha-O-linked disaccharide antigen on the surface of ~80% of human carcinomas, including breast, lung, colon, bladder, ovarian, and prostate cancers, and is cryptic on normal cells. JAA-F11 has potential, when humanized, for cancer immunotherapy for multiple cancer types. Humanization of JAA-F11, was performed utilizing complementarity determining regions grafting on a homology framework.

RNA-Generated and Gene-Edited Induced Pluripotent Stem Cells for Disease Modeling and Therapy.

Cellular reprogramming by epigenomic remodeling of chromatin holds great promise in the field of human regenerative medicine. As an example, human-induced Pluripotent Stem Cells (iPSCs) obtained by reprograming of patient somatic cells are sufficiently similar to embryonic stem cells (ESCs) and can generate all cell types of the human body. Clinical use of iPSCs is dependent on methods that do not utilize genome altering transgenic technologies that are potentially unsafe and ethically unacceptable.

Physiologically Based Pharmacokinetic (PBPK) Modeling of Metabolic Pathways of Bromochloromethane in Rats.

Bromochloromethane (BCM) is a volatile compound and a by-product of disinfection of water by chlorination. Physiologically based pharmacokinetic (PBPK) models are used in risk assessment applications. An updated PBPK model for BCM is generated and applied to hypotheses testing calibrated using vapor uptake data.

The impact of sexually abstaining groups on persistence of sexually transmitted infections in populations with ephemeral pair bonds.

Neoplastic transformation and tumorigenesis associated with sam68 protein deficiency in cultured murine fibroblasts.

Sam68 is a multimeric 68-kDa RNA-binding nuclear protein of unknown function that interacts with, and is tyrosine-phosphorylated by, the oncogenic protein Src during mitosis. Random homozygous knock-out (RHKO) is a retroviral-based antisense RNA strategy that can identify chromosomal genes whose functional disablement leads to reversible tumorigenic capabilities. Here we report that RHKO-induced Sam68 deficiency results in neoplastic transformation of murine NIH3T3 fibroblasts.

Modular bacterial artificial chromosome vectors for transfer of large inserts into mammalian cells.

To facilitate the use of large-insert bacterial clones for functional analysis, we have constructed new bacterial artificial chromosome vectors, pPAC4 and pBACe4. These vectors contain two genetic elements that enable stable maintenance of the clones in mammalian cells: (1) The Epstein-Barr virus replicon, oriP, is included to ensure stable episomal propagation of the large insert clones upon transfection into mammalian cells. (2) The blasticidin deaminase gene is placed in a eukaryotic expression cassette to enable selection for the desired mammalian clones by using the nucleoside antibiotic blasticidin.

Reversible tumorigenesis induced by deficiency of vasodilator-stimulated phosphoprotein.

Random homozygous knockout (RHKO) is an antisense RNA strategy capable of identifying genes whose homozygous functional inactivation yields a selectable phenotype in cells growing in culture. Using this approach, we isolated NIH 3T3 fibroblast clones that showed the ability to form colonies on 0.5% agar and tumors in nude mice.

CCG repeats in cDNAs from human brain.

Expansion mutations of trinucleotide repeats and other units of unstable DNA have been proposed to account for at least some of the genetic susceptibility to a number of neuropsychiatric disorders, including bipolar affective disorder, schizophrenia, autism, and panic disorder. To generate additional candidate genes for these and other disorders, cDNA libraries from human brain were probed at high stringency for clones containing CCG, CGC, GCC, CGG, GCG, and GGC repeats (referred to collectively as CCG repeats). Some 18 cDNAs containing previously unpublished or uncharacterized repeats were characterized for chromosomal locus, repeat length polymorphism, and similarity to genes of known function.

Direct gene transfer to the respiratory tract of mice with pure plasmid and lipid-formulated DNA.

Direct gene transfer into the respiratory system could be carried out for either therapeutic or immunization purposes. Here we demonstrate that cells in the lung can take up and express plasmid DNA encoding a luciferase reporter gene whether it is administered in naked form or formulated with cationic liposomes. Depending on the lipid used, the transfection efficiency with liposome-formulated DNA may be higher, the same as, or less than that with pure plasmid DNA.

Proximal and distal effects of sequence context on ultraviolet mutational hotspots in a shuttle vector replicated in xeroderma cells.

Hotspots are a standard feature of mutational spectra induced by mutagens in a variety of marker genes. While it is generally believed that sequence context exerts an important influence on hotspot location, direct experimental evidence is quite limited. We have studied ultraviolet mutagenesis in a suppressor tRNA marker gene (supF) carried in a mammalian shuttle vector and replicated in Xeroderma pigmentosum cells in culture.

Construction of primary and subtracted cDNA libraries from early embryos.

By modifying current cDNA cloning and electroporation methods, large and representative murine cDNA libraries were synthesized from 10 to 100 ng mRNA isolated from unfertilized egg and preimplantation mouse embryos. High cloning efficiency is essential for complete representation of genes expressed in egg and preimplantation embryos and for the isolation of stage-specific genes using subtractive hybridization. Because the mouse embryo contains no more than 50 pg of poly(A)+ mRNA at any stage of preimplantation development, approximately 5000-10,000 embryos are required to obtain enough mRNA to synthesize libraries using current methods.

DH11S: an Escherichia coli strain for preparation of single-stranded DNA from phagemid vectors.
