Model acetylcholinesterase-Fc fusion glycoprotein biotechnology system for the manufacture of an organophosphorus toxicant bioscavenging countermeasure.

Organophosphate (OP) toxicants remain an active threat to public health and to warfighters in the military. Current countermeasures require near immediate administration following OP exposure and are reported to have controversial efficacies. Acetylcholinesterase (AChE) fused to the human immunoglobulin 1 (IgG1) Fc domain (AChE-Fc) is a potential bioscavenger for OP toxicants, but a reproducible AChE-Fc biomanufacturing strategy remains elusive.

Identification of meaningful individual-level change thresholds for worsening on the patient-reported outcomes version of the common terminology criteria for adverse events (PRO-CTCAE®).

Background: We derived meaningful individual-level change thresholds for worsening in selected patient-reported outcomes version of the common terminology criteria for adverse events (PRO-CTCAE®) items and their composite scores.

Methods: We used two data sources, the PRO-TECT trial (Alliance AFT-39) that collected PRO-CTCAE data from adults with advanced cancer at 26 United States (U.S.

Who let the dogs out? A 10-year review of maxillofacial dog bite injuries.

Dog bites are common within the United Kingdom, with their incidence increasing over recent years. Bites to the head and neck region can have substantial and multifactorial implications for victims, and can provide a challenge to maxillofacial departments. This study is a 10-year retrospective review of head and neck dog bites that required input from the maxillofacial team within the Cwm Taf Morgannwg University Health Board.

Reactivation by novel pyridinium oximes of rat serum and skeletal muscle acetylcholinesterase inhibited by organophosphates.

The treatment of organophosphate (OP) anticholinesterases currently lacks an effective oxime reactivator of OP-inhibited acetylcholinesterase (AChE) which can penetrate the blood-brain barrier (BBB). Our laboratories have synthesized novel substituted phenoxyalkyl pyridinium oximes and tested them for their ability to promote survival of rats challenged with lethal doses of nerve agent surrogates. These previous studies demonstrated the ability of some of these oximes to promote 24-h survival to rats challenged with a lethal level of highly relevant surrogates for sarin and VX.

Impact of gender representativeness in online symptom survey and clinical trial participation among patients with myeloproliferative neoplasms.

Patients with myeloproliferative neoplasms (MPNs) face chronic symptom burden. Online symptom assessment studies allow for recruitment of large numbers of motivated patients, but patient self-selection can lead to sampling bias. This study evaluated how gender representativeness in MPN symptom surveys and trials impacted symptom score mean estimates, using data from 4825 survey respondents and 291 trial participants with MPNs.
