Reliable PCR amplification from Neurospora crassa genomic DNA obtained from conidia

Boil-mediated lysis of Neurospora conidia (Boil-prep) is an extremely rapid, convenient and useful technique to obtain sufficient genomic DNA template for PCR amplification. We routinely use this technique for screening molecular markers, sequencing, and preliminary confirmation of transformants

Establishing the acute physiological and sleep disruption characteristics of wind farm versus road traffic noise disturbances in sleep: a randomized controlled trial protocol

Advance access publication 6 September 2023Study Objectives: Despite the global expansion of wind farms, effects of wind farm noise (WFN) on sleep remain poorly understood. This protocol details a randomized controlled trial designed to compare the sleep disruption characteristics of WFN versus road traffic noise (RTN). Methods: This study was a prospective, seven night within-subjects randomized controlled in-laboratory polysomnography-based trial. Four groups of adults were recruited from; 15 s events) from sleep by each noise type with acute (20-s) and more sustained (3-min) noise exposures. Secondary analyses will compare dose–response effects of sound pressure level and noise type on EEG K-complex probabilities and quantitative EEG measures, and cardiovascular activation responses. Group effects, self-reported noise sensitivity, and wake versus sleep noise exposure effects will also be examined. Conclusions: This study will help to clarify if wind farm noise has different sleep disruption characteristics compared to road traffic noise.Gorica Micic, Branko Zajamsek, Bastien Lechat, Kristy Hansen, Hannah Scott, Barbara Toson, Tessa Liebich, Claire Dunbar, Duc Phuc Nguyen, Felix Decup, Andrew Vakulin, Nicole Lovato, Leon Lack, Colin Hansen, Dorothy Bruck, Ching Li Chai-Coetzer, Jeremy Mercer, Con Doolan and Peter Catchesid

Steps to prevent SUDEP: the validity of risk factors in the SUDEP and seizure safety checklist: a case control study

Our objectives were to compare people with epilepsy (PWE) who died of sudden unexpected death in epilepsy (SUDEP) with live controls using the risk factor items of the SUDEP and Seizure Safety Checklist. All 48 SUDEPs of 93 epilepsy deaths which occurred in Cornwall UK 2004–2012 were compared to 220 live controls using the SUDEP and Seizure Safety Checklist, an evidenced based tool used to communicate person centered risk of SUDEP to PWE. The odds ratio for having a specific factor in those who died was compared to controls and ranked according to P value using a sequential Bonferroni correction for multiple comparisons. Of the 17 modifiable and non-modifiable risk factors analyzed 9 were statistically significant of which 7 are potentially modifiable. Well known modifiable factors such as nocturnal monitoring, compliance and sleeping position featured prominently in the risk association. This is the first case control study exploring the risk factors for SUDEP since 2009. The findings are compared to the current considered risk factors as identified in a major recent review. The study further validates certain SUDEP risk factors. It highlights that the majority of risk factors strongly associated with SUDEP are potentially modifiable. There is an emerging profile to rank the risk factors. It furthers the evidence to use structured risk assessment and communication tools such as the SUDEP and Seizure Safety Checklist in daily clinical practice. It highlights key areas for a person centered discussion to empower PWE to mitigate risk

A rapid wire-based sampling method for DNA profiling*

First published: 28 December 2011This paper reports the results of a commission to develop a field deployable rapid short tandem repeat (STR)-based DNA profiling system to enable discrimination between tissues derived from a small number of individuals. Speed was achieved by truncation of sample preparation and field deployability by use of an Agilent 2100 Bioanalyser™. Human blood and tissues were stabbed with heated stainless steel wire and the resulting sample dehydrated with isopropanol prior to direct addition to a PCR. Choice of a polymerase tolerant of tissue residues and cycles of amplification appropriate for the amount of template expected yielded useful profiles with a custom-designed quintuplex primer set suitable for use with the Bioanalyser™. Samples stored on wires remained amplifiable for months, allowing their transportation unrefrigerated from remote locations to a laboratory for analysis using AmpFlSTR® Profiler Plus® without further processing. The field system meets the requirements for discrimination of samples from small sets and retains access to full STR profiling when required.Tong Chen, David E. A.
