An infertile male patient with a 45,X peripheral blood karyotype and a 45,X/46,X,del(Y)(pter----q11.1:) mosaic skin fibroblast karyotype is described. Steroid sulphatase (STS) activity was normal. Recombinant DNA studies using Y chromosome specific probes suggest that almost the entire long arm of the Y chromosome is deleted.

Significant progress in determining the molecular origins and resistance mechanisms of mantle cell lymphoma (MCL) has improved our understanding of the disease's clinical diversity. These factors greatly impact prognosis in MCL patients. Given the dynamic alterations in MCL clones and disease evolution, it is crucial to recognize high-risk prognostic factors at diagnosis and relapse.

Background: Sex is an important factor that contributes to both clinical and biological heterogeneity in Alzheimer's disease (AD), but the regulatory mechanisms underlying sex differences in AD are still not well understood. DNA methylation (DNAm) is an epigenetic modification that regulates gene transcription and is known to be involved in AD. However, due to analytical and biological complexity, few previous DNAm studies analyzed the X chromosome, where many genes influencing cognitive abilities and immune functions are located.

During sexual reproduction in the ciliate , meiosis occurs in the germline micronucleus, resulting in the formation of four haploid micronuclei. Of these, only one is selected to evade autophagy, and subsequently migrates to the membrane junction with the partner cell for reciprocal pronuclear exchange. We previously demonstrated that the transmembrane protein Semi1 is essential for this nuclear migration.

Background: Alzheimer's Disease (AD) is a common form of dementia among the elderly with a large percentage of estimated heritability. Conventional polygenic risk analysis only accounts for the linearly combined genomic effects of single nucleotide polymorphisms (SNPs). On the other hand, a deep-learning-based approach is able to uncover nonlinearly associated effects from data with high-dimensional features such as genomics.

Background: Obesity, diabetes, hypertension, hyperlipidemia, and depression are relevant Alzheimer's Disease (AD) modifiable risk factors (RFs). However, little is known about how the duration of these conditions, influenced by unmodifiable AD risk factors, such as chromosomal sex and APOE genotype, affects the associated risk. Modeling interactions between patient's temporal and clinical patterns, integrated with the probability of developing AD remains challenging, particularly when considering the multifactorial progression of AD.
