Purpose: Many patients with skull base meningiomas (SBMs) develop cranial neuropathies, though there is a paucity in literature regarding cranial neuropathy improvement following treatment. This is even more profound when isolating for patients who received stereotactic radiotherapy (SRT) as their primary treatment without additional open surgery. Our goal was to investigate the effect of SRT on cranial neuropathies secondary to SBMs and identify predictors of favourable treatment response.

Article Synopsis
  • Alzheimer's disease (AD) is more prevalent in women than in men, with factors beyond longevity, like metabolic changes, influencing this increased risk.
  • A study conducted metabolomic profiling of blood samples from male and female patients with mild cognitive impairment (MCI), revealing significant metabolic differences related to sex, particularly in lipid and peptide energy metabolism pathways.
  • The research identified specific metabolites unique to each sex, such as higher levels of 1-palmitoleoyl glycerol in females, suggesting these could be potential biomarkers to enhance our understanding of MCI and AD prevention strategies.

Alzheimer's disease (AD) affects more women than men. Although women live longer than men, it is not longevity alone, but other factors, including metabolic changes, that contribute to the higher risk of AD in women. Metabolic pathways have been implicated in AD progression, but studies to date examined targeted pathways, leaving many metabolites unmeasured.

Epigenetic clocks, DNA methylation-based predictive models of chronological age, are often utilized to study aging associated biology. Despite their widespread use, these methods do not account for other factors that also contribute to the variability of DNA methylation data. For example, many CpG sites show strong sex-specific or cell-type-specific patterns that likely impact the predictions of epigenetic age.

Background: Regression is an immunological phenomenon described in cutaneous melanoma whereby tumor is replaced with tumor-infiltrating lymphocytes, granulation tissue, and mature fibroblasts often accompanied by pigment incontinence (accumulation of melanin in the upper dermis). Pigment incontinence results in grossly pigmented lesions that may be mistaken for viable tumor and has not been described in sinonasal mucosal melanoma (SNMM). This study investigates the presence of regression and pigment incontinence in patients with SNMM.

Article Synopsis
  • Succulence refers to the ability of plants to store water in their tissues, helping them function and survive in dry conditions.* -
  • A study with nine shrub species showed that higher leaf and stem succulence leads to more usable water and a better ability to buffer changes in soil moisture.* -
  • However, while root succulence helps prolong the time before plants desiccate, it doesn’t necessarily delay overall water loss, indicating different roles for succulence in aboveground vs. root systems.*

Reference sequences and annotations serve as the foundation for many lines of research today, from organism and sequence identification to providing a core description of the genes, transcripts and proteins found in an organism's genome. Interpretation of data including transcriptomics, proteomics, sequence variation and comparative analyses based on reference gene annotations informs our understanding of gene function and possible disease mechanisms, leading to new biomedical discoveries. The Reference Sequence (RefSeq) resource created at the National Center for Biotechnology Information (NCBI) leverages both automatic processes and expert curation to create a robust set of reference sequences of genomic, transcript and protein data spanning the tree of life.

Maribavir is approved for management of post-transplant cytomegalovirus (CMV) infections refractory and/or resistant to CMV therapies at a dose of 400 mg twice daily (BID). Population pharmacokinetic (PopPK) and exposure-response analyses were conducted to support the appropriateness of 400 mg BID dosing. A PopPK model was developed using non-linear mixed-effects modeling with pooled maribavir plasma concentration-time data from phase 1 and 2 studies (from 100 mg up to 1200 mg as single or repeated doses) and the phase 3 SOLSTICE study (400 mg BID).

  • The study aimed to evaluate how high-intensity interval training (HIIT) affects the frequency and duration of hypoglycemia in individuals with type 1 diabetes and impaired awareness of hypoglycemia.
  • Researchers conducted a post-hoc analysis of four weeks of continuous glucose monitoring data from a study comparing HIIT plus monitoring versus no exercise.
  • Results indicated that HIIT did not increase overall hypoglycemia episodes and was associated with a significant reduction in nocturnal hypoglycemia compared to those who did not exercise.

The inbred Babraham pig serves as a valuable biomedical model for research due to its high level of homozygosity, including in the major histocompatibility complex (MHC) loci and likely other important immune-related gene complexes, which are generally highly diverse in outbred populations. As the ability to control for this diversity using inbred organisms is of great utility, we sought to improve this resource by generating a long-read whole genome assembly and transcriptome atlas of a Babraham pig. The genome was de novo assembled using PacBio long reads and error-corrected using Illumina short reads.
