Recent advances in machine perfusion have revolutionised the field of transplantation by prolonging preservation, permitting evaluation of viability prior to implant and rescue of discarded organs. Long-term perfusion for days-to-weeks provides time to modify these organs prior to transplantation. By using long-term normothermic machine perfusion to facilitate liver splitting and subsequent perfusion of both partial organs, possibilities even outside the clinical arena become possible.

Transposable Elements (TEs) are implicated in aging and neurodegenerative disorders, but the impact of brain TE RNA dynamics on these phenomena is not fully understood. Therefore, we quantified TE RNA changes in aging post-mortem human and mouse brains and in the neurodegenerative disorders Huntington's Disease (HD) and Parkinson's Disease (PD). We tracked TE small RNAs (smRNAs) expression landscape to assess the relationship to the active processing from TE long RNAs (lnRNAs).

Article Synopsis
  • Sensory stimuli gain motivational significance through learned associations, but there's still much to discover about how these associations are processed in the brain.
  • This study compared the mouse anteromedial olfactory tubercle (OT) and ventral pallidum (VP) to understand their roles in reward processing, revealing that OT neurons are mainly focused on identifying odors, while VP neurons primarily encode reward expectations.
  • Findings suggest that OT encodes complex odor identities in a detailed manner, whereas VP simplifies this information into a more general sense of reward, indicating a specialized mapping of sensory information to motivational value in the brain’s circuitry.

Nitroaromatic compounds are found in brown carbon aerosols emitted to the Earth's atmosphere by biomass burning, and are important organic chromophores for the absorption of solar radiation. Here, transient absorption spectroscopy spanning 100 fs-8 μs is used to explore the pH-dependent photochemical pathways for aqueous solutions of -nitrophenol, chosen as a representative nitroaromatic compound. Broadband ultrafast UV-visible and infrared probes are used to characterize the excited states and intermediate species involved in the multistep photochemistry, and to determine their lifetimes under different pH conditions.

Recent studies have suggested that Transposable Elements (TEs) residing in introns frequently splice into and alter primary gene-coding transcripts. To re-examine the exonization frequency of TEs into protein-coding gene transcripts, we re-analyzed a Drosophila neuron circadian rhythm RNAseq dataset and a deep long RNA fly midbrain RNAseq dataset using our Transposon Insertion and Depletion Analyzer (TIDAL) program. Our TIDAL results were able to predict several TE insertions from RNAseq data that were consistent with previous published studies.

Unlabelled: Transposable elements (TEs) pose a threat to genome integrity, and the piRNA pathway in animal gonads plays a crucial role in silencing TE activity. While the transcriptional regulation of the piRNA pathway components in germ cells has been documented in mice and flies, the mechanisms orchestrating the transcriptional program of the somatic piRNA pathway in ovaries remains unresolved. Here, we demonstrate that Traffic jam (Tj), an orthologue of a large Maf transcription factor in mammals, is a master regulator of the piRNA pathway in ovarian somatic cells, playing a crucial role in maintaining TE silencing and genomic integrity in somatic tissues.

  • The study focuses on a special group of genes called piRNAs that help female animals stay fertile by stopping bad DNA pieces known as transposons from becoming active.
  • Scientists experimented with parts of these genes to learn how they work and found that a protein called Traffic Jam helps control them.
  • By looking at the effects of reducing Traffic Jam, the researchers discovered that it not only affects the piRNAs but also helps prevent problems caused by the transposons.

Article Synopsis
  • There is a strong connection between math anxiety and math achievement, where higher anxiety levels generally lead to lower performance in math.
  • The review discusses two main theories: Reduced Competency Theory, which posits that low math skills can lead to increased anxiety, and Processing Efficiency Theory, which argues that anxiety distracts cognitive resources, hindering performance.
  • It introduces 'math avoidance' as a significant factor that mediates this relationship, indicating that avoidance behaviors can create a cycle that worsens both anxiety and math proficiency.
