Genome-wide association neural networks identify genes linked to family history of Alzheimer's disease.

Augmenting traditional genome-wide association studies (GWAS) with advanced machine learning algorithms can allow the detection of novel signals in available cohorts. We introduce "genome-wide association neural networks (GWANN)" a novel approach that uses neural networks (NNs) to perform a gene-level association study with family history of Alzheimer's disease (AD). In UK Biobank, we defined cases (n = 42 110) as those with AD or family history of AD and sampled an equal number of controls.

A retrospective study of the aetiology of increased mean platelet volume in dogs presented to a small animal teaching hospital in Greece.

Background: The aetiology of increased mean platelet volume in dogs is currently uncertain. Our aim was to investigate the aetiology of increased mean platelet volume in dogs with and without thrombocytopenia.

Methods: The database of a teaching hospital was retrospectively searched for dogs with increased mean platelet volume (>14.

Initiation and maintenance of the pluripotent epiblast in pre-implantation human development is independent of NODAL signaling.

The human blastocyst contains the pluripotent epiblast from which human embryonic stem cells (hESCs) can be derived. ACTIVIN/NODAL signaling maintains expression of the transcription factor NANOG and in vitro propagation of hESCs. It is unknown whether this reflects a functional requirement for epiblast development in human embryos.

Cerebral cortical encephalitis in adults with myelin oligodendrocyte glycoprotein antibody-associated disease: A national case series.

Background And Purpose: Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is a relatively recently described disease, most commonly presenting with optic neuritis and longitudinally extensive transverse myelitis. Cerebral cortical encephalitis is a rare manifestation of MOGAD.

Methods: We identified patients presenting with cerebral cortical encephalitis with positive MOG antibodies in serum across a large specialized service.

Stress Granule Assembly in Pulmonary Arterial Hypertension.

The role of stress granules (SGs) in pulmonary arterial hypertension (PAH) is unknown. We hypothesized that SG formation contributes to abnormal vascular phenotypes, and cardiac and skeletal muscle dysfunction in PAH. Using the rat Sugen/hypoxia (SU/Hx) model of PAH, we demonstrate the formation of SG puncta and increased expression of SG proteins compared to control animals in lungs, right ventricles, and soleus muscles.
