Background: Morphologic sex differences between males and females typically emerge after the primordial germ cell migration and gonad formation, although sex is determined at fertilization based on chromosome composition. A key debated sexual difference is the embryonic developmental rate, with in vitro produced male embryos often developing faster. However, the molecular mechanisms driving early embryonic sex differences remain unclear.

Diffusion Tensor Imaging (DTI) is a crucial imaging technique for accurately assessing pathological changes in Cervical Spondylotic Myelopathy (CSM). However, the segmentation of spinal cord DTI images primarily relies on manual methods, which are labor-intensive and heavily dependent on the subjective experience of clinicians, and existing research on DTI automatic segmentation cannot fully satisfy clinical requirements. Thus, this poses significant challenges for DTI-assisted diagnostic decision-making.

In this study, we report a highly sensitive CRISPR/Cas13a-based electrochemiluminescence (ECL) biosensor for detecting α-synuclein oligomers, early biomarkers for neurodegenerative diseases. The system integrates aptamer recognition, T7 transcription, CRISPR/Cas13a cleavage, and EXPAR amplification. α-Synuclein binding triggers the release of the T7 promoter, leading to RNA production that activates Cas13a, initiating collateral cleavage and EXPAR, generating double-stranded DNA that interacts with [Ru(phen)₂dppz] to produce a measurable ECL signal.

Since the first description of a set of characteristics of aging as so-called hallmarks or pillars in 2013/2014, these characteristics have served as guideposts for the research in aging biology. They have been examined in a range of contexts, across tissues, in response to disease conditions or environmental factors, and served as a benchmark for various anti-aging interventions. While the hallmarks of aging were intended to capture generalizable characteristics of aging, they are derived mostly from studies of rodents and humans.

(Lepidoptera: Crambidae) is a severe pest of plants, which produce high-priced agarwood. The larval stage of this pest is gregarious, usually forming large aggregates during young instars and becoming solitary during the fifth instar. We hypothesize that the cuticle chemicals of young-instar larvae could promote larval aggregating, whereas the cuticle chemicals of late-instar larvae would no longer attract young-instar larvae.

Article Synopsis
  • High linear energy transfer (LET) radiation enhances tumor-killing, but the link between LET and treatment success in Carbon-ion radiotherapy (CIRT) for locally advanced non-small-cell lung cancer (LA-NSCLC) is unclear.
  • The study analyzed data from 62 patients treated with CIRT and found that lower mean LET values in the tumor were associated with increased local recurrence rates.
  • Results indicated that a significant threshold of LET (at least 40 keV/µm) can help predict local recurrence, highlighting the importance of LET distribution in improving treatment outcomes for LA-NSCLC.

Rice blast, caused by rice blast fungus (Magnaporthe oryzae), is a global threat to food security, with up to 50% yield losses. Panicle blast is a severe form of rice blast, and disease responses vary between cultivars with different genotypes. Reactive oxygen species (ROS)-mediated signaling reactions and the phenylpropanoid pathway are important defense mechanisms involved in recognizing and resisting against fungal infection.

Mesenchymal stromal cells (MSCs) have the potential to be used as therapeutics, but their efficacy varies due to cellular heterogeneity, which is not fully understood. After characterizing donor-matched bovine MSC from adipose tissue (AT), bone marrow (BM), and peripheral blood (PB), we performed single-cell RNA sequencing (scRNA-seq) to evaluate overarching similarities and differences across these three tissue-derived MSCs. Next, the transcriptomic profiles of the bovine MSCs were compared to those of equine MSCs, derived from the same tissue sources and previously published by our group, and revealed species-specific differences.

Chloroplast and mitochondrial DNA (cpDNA and mtDNA) are apart from nuclear DNA (nuDNA) in a eukaryotic cell. The transcription system of chloroplasts differs from those of mitochondria and eukaryotes. In contrast to nuDNA and animal mtDNA, the transcription of cpDNA is still not well understood, primarily due to the unresolved identification of transcription initiation sites (TISs) and transcription termination sites (TTSs) on the genome scale.

The progression and remission of cervical spondylotic myelopathy (CSM) are quite unpredictable due to the ambiguous pathomechanisms. Spontaneous functional recovery (SFR) has been commonly implicated in the natural course of incomplete acute spinal cord injury (SCI), while the evidence and underlying pathomechanisms of neurovascular unit (NVU) compensation involved in SFR remains poorly understood in CSM. In this study, we investigate whether compensatory change of NVU, in particular in the adjacent level of the compressive epicenter, is involved in the natural course of SFR, using an established experimental CSM model.

Among patients with cervical myelopathy, the most common level of stenosis at spinal cord of all ages was reported to be between cervical levels C5-6. Previous studies found that time-frequency components (TFCs) of somatosensory evoked potentials (SEPs) possess location information of spinal cord injury (SCI) in single-level deficits in the spinal cord. However, the clinical reality is that there are multiple compressions at multiple spinal cord segments.
