Overcoming barriers for investigating nickel-pincer nucleotide cofactor-related enzymes.

Unlabelled: The nickel-pincer nucleotide (NPN) cofactor is a modified pyridinium mononucleotide that tri-coordinates nickel and is crucial for the activity of certain racemases and epimerases. LarB, LarC, and LarE are responsible for NPN synthesis, with the cofactor subsequently installed into LarA homologs. Hurdles for investigating the functional properties of such proteins arise from the difficulty of obtaining the active, NPN cofactor-loaded enzymes and in assaying their diverse reactivities.

Application of calcium sulfate as graft material in implantology and maxillofacial procedures: A review of literature.

Calcium sulphate (plaster of Paris) has been used since 1892 to fill bone defects and as a good bone graft substitute. Calcium sulphate is an osteoconductive, inorganic substance. Following 75 years, many other authors reported variable and a better result in grafting of bone defects and in several cases of immediate and delayed dental implants for good osseointegrations, with no complications attributed to the calcium sulphate.

Association Between Clinical Severity, Neuroimaging, and Electroencephalographic Findings in Children with Subacute Sclerosing Panencephalitis.

Background: Children diagnosed with subacute sclerosing panencephalitis (SSPE) display a range of neuroimaging abnormalities during different stages of the disease, but their exact clinical significance remains unclear.

Methods: In this retrospective cohort study, our objective was to examine magnetic resonance imaging (MRI) abnormalities in the brains of patients aged 18 years or younger with subacute sclerosing panencephalitis. We aimed to correlate these MRI abnormalities with clinical severity, sociodemographic variables, electroencephalographic (EEG) abnormalities, and cerebrospinal anti-measles antibody titers.

Parkinson's-linked LRRK2-G2019S derails AMPAR trafficking, mobility, and composition in striatum with cell-type and subunit specificity.

Parkinson's disease (PD) is a multifactorial disease that affects multiple brain systems and circuits. While defined by motor symptoms caused by degeneration of brainstem dopamine neurons, debilitating non-motor abnormalities in fronto-striatal-based cognitive function are common, appear early, and are initially independent of dopamine. Young adult mice expressing the PD-associated G2019S missense mutation in also exhibit deficits in fronto-striatal-based cognitive tasks.

Lassa fever research priorities: towards effective medical countermeasures by the end of the decade.

In 2016, WHO designated Lassa fever a priority disease for epidemic preparedness as part of the WHO Blueprint for Action to Prevent Epidemics. One aspect of preparedness is to promote development of effective medical countermeasures (ie, diagnostics, therapeutics, and vaccines) against Lassa fever. Diagnostic testing for Lassa fever has important limitations and key advancements are needed to ensure rapid and accurate diagnosis.

Parkinson's LRRK2-G2019S risk gene mutation drives sex-specific behavioral and cellular adaptations to chronic variable stress.

Anxiety is a psychiatric non-motor symptom of Parkinson's that can appear in the prodromal period, prior to significant loss of brainstem dopamine neurons and motor symptoms. Parkinson's-related anxiety affects females more than males, despite the greater prevalence of Parkinson's in males. How stress, anxiety and Parkinson's are related and the basis for a sex-specific impact of stress in Parkinson's are not clear.

Detection of intrinsic transcription termination sites in bacteria: consensus from hairpin detection approaches.

We compare the WebGeSTer and INtrinsic transcription TERmination hairPIN (INTERPIN) databases used for intrinsic transcription termination (ITT) site prediction in bacteria. The former deploys inverted nucleotide repeat detection for identification of RNA hairpin, while the latter a pair-potential function - the hairpin energy score evaluation being identical for both. We find INTERPIN more sensitive than WebGeSTer with about 6% and 51% additional predictions for ITTs in chromosomal and plasmid operons, respectively.

Innovation in the field, including TCR-T, allogeneic or "off the shelf" CAR-T, and autoantigen/armored CAR-Ts are likely to increase the efficacy and applications of these therapies. The unique aspects of these cell-based therapeutics; patient-derived cells, intracellular expression, in vivo expansion, and phenotypic changes provide unique bioanalytical challenges to develop pharmacokinetic and immunogenicity assessments.

Biotransformation of 2,4,6-trinitrotoluene by Diaphorobacter sp. strain DS2.

Diaphorobacter strain DS2 degrades 3-nitrotoluene and 2-nitrotoluene via ring oxidation with 3-nitrotoluene dioxygenase (3NTDO). In the current study, we hypothesized that 3NTDO might also be involved in the degradation of 2,4,6-trinitrotoluene (TNT), a major nitroaromatic explosive contaminant in soil and groundwater. Strain DS2 transforms TNT as a sole carbon and nitrogen source when grown on it.
