Among them, 67.7% reported daily pain, 53.2% screened positive for PTSD, 38.7% reported a new functional limitation in an activity of daily living, and 59.1% have not returned to work. Compared with population norms, overall physical and mental health-related quality of life was significantly reduced among firearm injury survivors. Compared with matched MVC survivors (n = 255), firearm injury survivors were significantly more likely to have daily pain [adjusted odds ratio (OR) 2.30, 95% confidence interval (CI) 1.08-4.87], to screen positive for PTSD (adjusted OR 3.06, 95% CI 1.42-6.58), and had significantly worse physical and mental health-related quality of life. Conclusions This study highlights the need for targeted long-term follow-up care, physical rehabilitation, mental health screening, and interventions for survivors of firearm violence.The movement of intracellular cargo, such as transcripts, proteins, and organelles, is fundamental to cellular function. Neurons, due to their long axons and dendrites, are particularly dependent on proper intracellular trafficking and vulnerable to defects in the movement of intracellular cargo that are noted in neurodegenerative and neurodevelopmental disorders. Thiomyristoyl Accurate quantification of intracellular transport is therefore needed for studying the mechanisms of cargo trafficking, the influence of mutations, and the effects of potentially therapeutic pharmaceuticals. In this article, we introduce an algorithm called "Kymolyzer." The algorithm can quantify intracellular trafficking along a defined path, such as that formed by the aligned microtubules of axons and dendrites. Kymolyzer works as a semi-autonomous kymography software application. It constructs and analyzes kymographs to measure the movement and distribution of fluorescently tagged objects along a user-defined path. The algorithm can be used under a wide variety of experimental conditions and can extract a diverse array of motility parameters describing intracellular movement, including time spent in motion, percentage of objects in motion, percentage of objects that are stationary, and velocities of motile objects. This article serves as a user manual describing the design of Kymolyzer, providing a stepwise protocol for its use and illustrating its functions with common examples. © 2020 Wiley Periodicals LLC Basic Protocol Kymolyzer, a semi-autonomous kymography tool to analyze intracellular motility.This protocol describes a method based on iodine and a base as mild coupling reagents to synthetize deoxyribonucleic guanidines (DNGs)-oligodeoxynucleotide analogues with a guanidine backbone. DNGs display unique properties, such as high cellular uptake with low toxicity and increased stability against nuclease degradation, but have been impeded in their development by the requirement for toxic and iterative manual synthesis protocols. The novel synthesis method reported here eliminates the need for the toxic mercuric chloride and pungent thiophenol that were critical to previous DNG synthesis methods and translates their synthesis to a MerMadeTM 12 automated oligonucleotide synthesizer. This method can be used to synthesize DNG strands up to 20 bases in length, along with 5'-DNG-DNA-3' chimeras, at 1- to 5-μmol scales in a fully automated manner. We also present detailed and accessible instructions to adapt the MerMadeTM 12 oligonucleotide synthesizer to enable the parallel synthesis of DNG and DNA/RNA oligonucleotides. Because DNG linkages alter the overall charge of the oligonucleotides, we also describe purification strategies to generate oligonucleotides with varying lengths and numbers of DNGs, based on extraction or preparative-scale gel electrophoresis, along with methods to characterize the final products. Overall, this article provides an overview of the synthesis, purification, and handling of DNGs and mixed-charge DNG-DNA oligonucleotides. © 2020 Wiley Periodicals LLC.

We set out to determine whether FMOD could be of help in diagnosing borderline lymphoproliferative disorders (LPD). Methods We established 3 flow cytometry-defined groups (CLL [n = 65], borderline LPD [n = 28], broadly defined as those with CLLflow score between 35 and -20 or discordant CD43 and CLLflow, and non-CLL LPD [n = 40]). FMOD expression levels were determined by standard RT-PCR in whole-blood samples. Patients were included regardless of lymphocyte count but with tumor burden ≥40%. Results FMOD expression levels distinguished between CLL (median 98.5, interquartile range [IQR] 37.8-195.1) and non-CLL LPD (median 0.012, IQR 0.003-0.033) with a sensitivity and specificity of 1. Most borderline LPDs were CD5/CD23/CD200-positive with no loss of B-cell antigens and negative or partial expression of CD43. 16/22 patients with available cytogenetic analysis showed trisomy 12. In 25/28 (89%) of these patients, FMOD expression levels fell between CLL and non-CLL (median 3.58, IQR 1.06-6.21). Discussion This study could suggest that borderline LPDs may constitute a distinct group laying in the biological spectrum of chronic leukemic LPDs. Future studies will have to confirm these results with other biological data. Quantification of FMOD can potentially be of help in the diagnosis of phenotypically complex LPDs.Background Promoter hypermethylation is common in Breast Cancer (BC) with studies mainly in histological specimens showing frequent methylation of tumor suppressor genes (TSGs) compared with normal tissues. The aim of this study was to estimate the frequency of promoter methylation of RAR-β2 and RASSF1A genes in breast FNAB material aiming to evaluate the methylation status of these two genes as biomarker for detecting BC in Greek population. Methods FNAB material from 104 patients was collected for cytological evaluation and epigenetic analysis. DNA was extracted and subjected to bisulfite conversion. A methylation-specific PCR was carried out and the final products were separated with electrophoresis in 2% agarose gels. Results From 104 samples, RASSF1A hypermethylation was observed in 78 (75%) and RAR-β2 hypermethylation in 64 (61.6%). 84% and 78% of the cases diagnosed with breast malignancy (n = 50) were methylated for RASSF1A and RAR-β2, respectively. Methylated RASSF1A and RAR-β2 were also detected in 88.
