The Combination of Trametinib and Ganitumab is Effective in RAS-Mutated PAX-Fusion Negative Rhabdomyosarcoma Models.

Purpose: PAX-fusion negative rhabdomyosarcoma (FN RMS) is driven by alterations in the RAS/MAP kinase pathway and is partially responsive to MEK inhibition. Overexpression of IGF1R and its ligands is also observed in FN RMS. Preclinical and clinical studies have suggested that IGF1R is itself an important target in FN RMS.

Evaluation of an Occupational Safety and Health Training for Cannabis Cultivation Workers.

Objectives: As the commercial cannabis industry grows, there is an increased need to characterize potentially hazardous workplace exposures and provide training to workers to mitigate these exposures with the goal of reducing accidents and injuries from cannabis cultivation, processing, and manufacturing. Public health and safety stakeholders in Colorado developed a worker-focused training designed to improve hazard awareness, recognition, and controls related to commercial cannabis cultivation. This paper describes the evaluation of this training.

Eosinophils Do Not Drive Acute Muscle Pathology in the mdx Mouse Model of Duchenne Muscular Dystrophy.

Eosinophils are present in muscle lesions associated with Duchenne muscular dystrophy and dystrophin-deficient mdx mice that phenocopy this disorder. Although it has been hypothesized that eosinophils promote characteristic inflammatory muscle damage, this has not been fully examined. In this study, we generated mice with the dystrophin mutation introduced into PHIL, a strain with a transgene that directs lineage-specific eosinophil ablation.

Current Marijuana Use by Industry and Occupation - Colorado, 2014-2015.

The effects of marijuana use on workplace safety are of concern for public health and workplace safety professionals. Twenty-nine states and the District of Columbia have enacted laws legalizing marijuana at the state level for recreational and/or medical purposes. Employers and safety professionals in states where marijuana use is legal have expressed concerns about potential increases in occupational injuries, such as on-the-job motor vehicle crashes, related to employee impairment.

Splenogonadal fusion: a rare etiology of solid testicular mass.

A 35-year-old man presented with a painless left scrotal mass. Pathologic examination after orchiectomy revealed splenogonadal fusion. Splenogonadal fusion is an exceptionally rare, typically benign, congenital anomaly.

Optimizing Frozen Sample Preparation for Laser Microdissection: Assessment of CryoJane Tape-Transfer System®.

Laser microdissection is an invaluable tool in medical research that facilitates collecting specific cell populations for molecular analysis. Diversity of research targets (e.g.

Tissue preparation for MALDI-MS imaging of protein and peptides.

Matrix-assisted laser desorption/ionization (MALDI) imaging is rapidly gaining importance in the -biomarkers field because it is able to detect several analytes at the same time and to assign to each one of them not only an m/z value but also spatial distribution. Here we present the detailed description of sample preparation for protein and peptide MALDI imaging assays. This chapter describes the microtomy performed in a cryostat to produce tissue slides mounted onto glass slides suitable for MALDI.

Increased calcium levels and prolonged shelf life in tomatoes expressing Arabidopsis H+/Ca2+ transporters.

Here we demonstrate that fruit from tomato (Lycopersicon esculentum) plants expressing Arabidopsis (Arabidopsis thaliana) H(+)/cation exchangers (CAX) have more calcium (Ca2+) and prolonged shelf life when compared to controls. Previously, using the prototypical CAX1, it has been demonstrated that, in yeast (Saccharomyces cerevisiae) cells, CAX transporters are activated when the N-terminal autoinhibitory region is deleted, to give an N-terminally truncated CAX (sCAX), or altered through specific manipulations. To continue to understand the diversity of CAX function, we used yeast assays to characterize the putative transport properties of CAX4 and N-terminal variants of CAX4.

Genetic manipulation for enhancing calcium content in potato tuber.

Increased calcium (Ca) in potatoes may increase the production rate by enhancing tuber quality and storability. Additionally, increased Ca levels in important agricultural crops may help ameliorate the incidence of osteoporosis. However, the capacity to alter Ca levels in potato tubers through genetic manipulations has not been previously addressed.

Efficient and genotype-independent Agrobacterium--mediated tomato transformation.

An efficient method to transform five cultivars of tomato (Lycopersicon esculentum), Micro-Tom, Red Cherry, Rubion, Piedmont, and E6203 is reported. A comparison was made of leaf, cotyledon, and hypocotyl explants on 7 different regeneration media without Agrobacterium tumefaciens cocultivation and on 11 different media with cocultivation. Although all cultivars and explants formed callus and regenerated on the initial 7 media, cocultivation with A.

How accurate is frozen section for skin cancers?

Frozen section analysis has been used to increase the likelihood of complete excision of skin cancers and to minimize the risk for recurrence. The question of its accuracy has been addressed in many studies and this article adds data to the discussion. A retrospective study was performed of 60 consecutive cases in which frozen section diagnoses were compared with permanent sections.

An evaluation of the Man to Man self-help group in Colorado and Utah.

Purpose: Two surveys were conducted to evaluate the Man to Man program, a prostate cancer self-help group of the American Cancer Society (ACS).

Description Of Study: The study involved two surveys in Colorado and Utah in 2001, one of program participants, the other of area urologists, respectively. A focus group also was conducted of African American men with prostate cancer in Denver, Colo.
