Abstract Objectives An increasing body of evidence indicates altered DNA methylation in Parkinson's disease, yet the reproducibility and utility of such methylation changes are largely unexplored. We aimed to further elucidate the role of dysregulated DNA methylation in Parkinson's disease and to evaluate the biomarker potential of methylation‐based ...

Relationship of cognitive decline with glucocerebrosidase activity and amyloid‐beta 42 in DLB and PD
Abstract Objective Dementia with Lewy bodies (DLB) and Parkinson's disease (PD) share clinical, pathological, and genetic risk factors, including GBA1 and APOEε4 mutations. Biomarkers associated with the pathways of these mutations, such as glucocerebrosidase enzyme (GCase) activity and amyloid‐beta 42 (Aβ42) levels, may hold potential as predictive ...

Staphylococcus aureus still resembles one of the primary causes of food poisoning induced specifically by milk and its products. Recent studies from neighbor countries of Iraq showed the presence of this bacterium in the milk of cattle, sheep, and goat.

Micropropagation of three genotypes of Indian mustard [{Brassica juncea} (L.) Czern.] using seedling-derived transverse thin cell layer (tTCL) explants [PDF]
Micropropagation of three genotypes of Indian mustard [\textit{Brassica juncea} (L.) Czern.] using 7-days old seedling-derived transverse thin cell layer (tTCL) explants was accomplished. The genotype, explant source and addition of silver nitrate to the medium significantly influenced shoot bud induction.

Heterozygous variants in AP4S1 are not associated with a neurological phenotype
Abstract Biallelic loss‐of‐function variants in AP4S1 cause childhood‐onset hereditary spastic paraplegia. A recent report suggested that heterozygous AP4S1 variants lead to a syndrome of lower limb spasticity and dysregulation of sphincter function. We critically evaluate this claim against clinical observations in 28 heterozygous carriers of the same

Sympatric speciation: compliance with phenotype diversification from a single genotype [PDF]
A novel mechanism for sympatric speciation that takes into account complex bio-processes within each individual organism is proposed. According to dynamical systems theory, organisms with identical genotypes can possess differentiated physiological states and may coexist `symbiotically' through appropriate mutual interaction.

Targeted Long‐Read Sequencing as a Single Assay Improves the Diagnosis of Spastic‐Ataxia Disorders
ABSTRACT Objective The hereditary spastic‐ataxia spectrum disorders are a group of disabling neurological diseases. The traditional genetic testing pathway is complex, multistep and leaves many cases unsolved. We aim to streamline and improve this process using long‐read sequencing. Methods We developed a targeted long‐read sequencing strategy with the

ABSTRACTObjectiveCerebrospinal fluid (CSF) orexin‐A has been suggested to be a biomarker of Alzheimer disease (AD). In both cognitively unimpaired healthy older adults and individuals with symptomatic AD, CSF orexin‐A is positively associated with CSF Aβ42, p‐tau181, and total tau (t‐tau) concentrations.

Genotypes of irreducible representations of finite p-groups [PDF]
For any characteristic zero coefficient field, an irreducible representation of a finite $p$-group can be assigned a Roquette $p$-group, called the genotype. This has already been done by Bouc and Kronstein in the special cases Q and C. A genetic invariant of an irrep is invariant under group isomorphism, change of coefficient field, Galois conjugation,
