Enhancing nature's palette through the epigenetic breeding of flower color in chrysanthemum.

Flower color is an important character of ornamental plants and one of the main target traits for variety innovation. We previously identified a CmMYB6 epigenetic allele that affects the flower color in chrysanthemum, and changes in flower color are caused by the DNA methylation level of this gene. However, it is still unknown which DNA methyltransferases are involved in modifying the DNA methylation levels of this gene.

Genome-Wide Network Analysis of DRG-Sciatic Nerve Network-Inferred Cellular Senescence and Senescence Phenotype in Peripheral Sensory Neurons.

Accumulation of senescent neurons in the dorsal root ganglion (DRG) is an important tissue phenotype that causes age-related degeneration of peripheral sensory nerves. Senescent neurons are neurons with arrested cell cycle that have undergone cellular senescence but remain in the tissue and play various biological roles. To understand the accumulation of senescent neurons in the DRG during aging, we aimed to elucidate the mechanism that induces cellular senescence in DRG neurons and the role of senescent DRG neurons.

Patients And Methods: Patients diagnosed with extensive-stage small cell lung cancer at our hospital between September 2019 and August 2023, who were treated with atezolizumab plus carboplatin and etoposide and had pathological tissue immunostained with SP142, were retrospectively examined to determine whether treatment efficacy differed depending on the expression of PD-L1.

Results: Twenty-nine patients were analyzed.

Right Posterior Segment Graft in Adult Living-Donor Liver Transplantation: A Report of 17 Years of Experience at a Single Institution.

Objectives: The right posterior segment graft can be selected in cases where neither the right nor left lobe graft satisfies the selection criteria for adult living donor liver transplant. However, vascular and biliary anatomy may cause technical difficulties in procurement of posterior segments in donors of living donor liver transplant and may require specific attention in vascular and biliary reconstruction in the recipient. In this study, we examined the feasibility of right posterior segment grafts in adult living donor liver transplants through donor safety and recipient outcomes and clarified the anatomic points of the surgical technique.

Possible negative impact of polypharmacy on surgical outcomes in older patients with lumbar spinal stenosis.

Aim: Older patients with lumbar spinal stenosis (LSS) have a higher incidence of polypharmacy attributed to comorbidities and the use of pain relief medications. This study aimed to explore the effect of polypharmacy and hyperpolypharmacy on surgical outcomes in older patients with LSS based on health-related quality of life (HRQOL) and locomotive syndrome.

Methods: Consecutive patients aged ≥65 years who underwent lumbar spinal surgery for LSS were retrospectively reviewed.

[Association of Gut and Oral Microbiota with Cerebral Aneurysms].

In recent years, the association of the microbiome with various diseases has been reported. The oral and gut microbiomes have been linked to cerebral aneurysms and are involved in the systemic inflammatory response, which is mediated mainly via the immune system. Chronic inflammation plays an important role in the pathogenesis and rupture of cerebral aneurysms, and the microbiome is potentially involved in this process.
