• Actomyosin contraction in the follicular epithelium provides the major mechanical force for follicle rupture during <em>Drosophila</em> ovulation September 18, 2024
  Ovulation is critical for sexual reproduction and consists of the process of liberating fertilizable oocytes from their somatic follicle capsules, also known as follicle rupture. The mechanical force for oocyte expulsion is largely unknown in many species. Our previous work demonstrated that Drosophila ovulation, as in mammals, requires the proteolytic degradation of the posterior follicle […]

• C1ql1 expression in oligodendrocyte progenitor cells promotes oligodendrocyte differentiation September 11, 2024
  Myelinating oligodendrocytes arise from the stepwise differentiation of oligodendrocyte progenitor cells (OPCs). Approximately 5% of all adult brain cells are OPCs. Why would a mature brain need such a large number of OPCs? New myelination is possibly required for higher-order functions such as cognition and learning. Additionally, this pool of OPCs represents a source of […]

• Glial modulation of synapse development and plasticity: oligodendrocyte precursor cells as a new player in the synaptic quintet September 11, 2024
  Synaptic communication is an important process in the central nervous system that allows for the rapid and spatially specified transfer of signals. Neurons receive various synaptic inputs and generate action potentials required for information transfer, and these inputs can be excitatory or inhibitory, which collectively determines the output. Non-neuronal cells (glial cells) have been identified […]

• Ultraplex microscopy: versatile highly-multiplexed molecular labeling and imaging across scale and resolution September 4, 2024
  The molecular organization of cells and tissue is challenging to study due to the inefficiency of multiplexed molecular labeling methods and the limited options for combining microscopy modalities in a single specimen, especially when high spatial resolution is needed. Here we describe ultraplex microscopy, which combines serial multiplexing, ultrathin sectioning, and reversible embedding to circumvent […]

• Evaluation of Pain-Associated Behavioral Changes in Monoiodoacetate-Induced Osteoarthritic Rats Using Dynamic Weight Bearing Analysis August 29, 2024
  Pain is the primary clinical indication of osteoarthritis (OA), and behavioral assessments in rodent pain models are widely used to understand pain patterns. These preclinical pain assessments can also help us to understand the effectiveness of emerging therapeutics for prolonged OA pain management. Along with evoked methods like mechanical allodynia and thermal hyperalgesia, non-evoked methods […]

• LRRK2 in Parkinson's disease: upstream regulation and therapeutic targeting August 17, 2024
  Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common causes of Parkinson's disease (PD) to date. Dysfunction in LRRK2 enzymatic activities and elevated protein levels are associated with the disease. How is LRRK2 activated, and what downstream molecular and cellular processes does LRRK2 regulate? Addressing these questions is crucial to decipher the disease […]

• Ventricular-subventricular zone stem cell niche adaptations in a mouse model of post-infectious hydrocephalus August 15, 2024
  Congenital post-infectious hydrocephalus (PIH) is a condition characterized by enlargement of the ventricular system, consequently imposing a burden on the associated stem cell niche, the ventricular-subventricular zone (V-SVZ). To investigate how the V-SVZ adapts in PIH, we developed a mouse model of influenza virus-induced PIH based on direct intracerebroventricular injection of mouse-adapted influenza virus at […]

• The prevalence and patterns of hearing loss in Jordan: A cross-sectional study August 15, 2024
  CONCLUSION: The rate of hearing loss in Jordan is higher than worldwide prevalence, which was assumed to be due to genetic factors impacting the auditory system. These findings will assist in creating effective hearing conservation programs to reasonably prevent or minimize the spread of hearing loss in Jordan.

• Neural Delays in Processing Speech in Background Noise Minimized after Short-Term Auditory Training July 26, 2024
  Background noise disrupts the neural processing of sound, resulting in delayed and diminished far-field auditory-evoked responses. In young adults, we previously provided evidence that cognitively based short-term auditory training can ameliorate the impact of background noise on the frequency-following response (FFR), leading to greater neural synchrony to the speech fundamental frequency(F0) in noisy listening conditions. […]

• Myelin basic protein mRNA levels affect myelin sheath dimensions, architecture, plasticity, and density of resident glial cells July 18, 2024
  Myelin Basic Protein (MBP) is essential for both elaboration and maintenance of CNS myelin, and its reduced accumulation results in hypomyelination. How different Mbp mRNA levels affect myelin dimensions across the lifespan and how resident glial cells may respond to such changes are unknown. Here, to investigate these questions, we used enhancer-edited mouse lines that […]

• 3D Biological/Biomedical Image Registration with enhanced Feature Extraction and Outlier Detection July 15, 2024
  In various applications, such as computer vision, medical imaging and robotics, three-dimensional (3D) image registration is a significant step. It enables the alignment of various datasets into a single coordinate system, consequently providing a consistent perspective that allows further analysis. By precisely aligning images we can compare, analyze, and combine data collected in different situations. […]

• Sex differences in neural projections of fear memory processing in mice and humans July 10, 2024
  It remains unexplored in the field of fear memory whether functional neuronal connectivity between two brain areas is necessary for one sex but not the other. Here, we show that chemogenetic silencing of centromedial (CeM)-Tac2 fibers in the lateral posterior BNST (BNSTpl) decreased fear memory consolidation in male mice but not females. Optogenetic excitation of […]

• Taxonomy of introns and the evolution of minor introns June 29, 2024
  Classification of introns, which is crucial to understanding their evolution and splicing, has historically been binary and has resulted in the naming of major and minor introns that are spliced by their namesake spliceosome. However, a broad range of intron consensus sequences exist, leading us to here reclassify introns as minor, minor-like, hybrid, major-like, major […]
