Department of Neurosurgery, Guangzhou Red Cross Hospital, Jinan University, Guangzhou, China.
Objective: Potassium voltage-gated channel sub-family A member 1 (Kv1.1), as a shaker homolog potassium channel, displays a special mechanism for posttranscriptional regulation called RNA editing. Adenosine deaminase acting on RNA 2 (ADAR2) can cause abnormal editing or loss of normal editing, which results in cell damage and related diseases.

Bone consists of a complex mineralised matrix that is maintained by a controlled equilibrium of synthesis and resorption by different cell types. Hyaluronan (HA) is an important glycosaminoglycan in many tissues including bone. Previously, the importance of HA synthesis for bone development during embryogenesis has been shown.

Background: Although separate lines of research indicated a moderating role of sex in both sleep-wake disruption and in the interindividual vulnerability to Alzheimer's disease (AD)-related processes, the quantification of sex differences in the interplay between sleep-wake dysregulation and AD pathology remains critically overlooked. Here, we examined sex-specific associations between circadian rest-activity patterns and AD-related pathophysiological processes across the adult lifespan.
Methods: Ninety-two cognitively unimpaired adults (mean age = 59.
Combined Solid Organ Transplant and Transfusion-Associated Graft-Versus-Host Disease in a Lung Transplant Recipient: An Uncertain Culprit With Lethal Complications.
Case Rep Transplant

Norton Thoracic Institute, St. Joseph's Hospital and Medical Center, Phoenix, Arizona, USA.
Although graft-versus-host disease (GVHD) is a common complication of hematopoietic stem cell transplantation, it is rare after solid organ transplantation (SOT) or blood transfusion. We present a rare case of SOT-derived and/or transfusion-associated graft-versus-host disease (TA-GVHD) in a 66-year-old man with interstitial lung disease who underwent bilateral lung transplantation (LT) from a 12-year-old female donor and required three units of packed red blood cells intraoperatively. He presented with signs and symptoms consistent with GVHD, and a bone marrow biopsy revealed an XX karyotype.

The study by López-Gómez , reports a significantly low prevalence (4.5%) of () infection in esophageal cancer patients, contrasting sharply with the general population's infection rate. This finding challenges the established negative association between and gastric malignancies, suggesting a potential protective role of against esophageal carcinoma, particularly in the context of widespread proton pump inhibitor use.
