EPISeg: Automated segmentation of the spinal cord on echo planar images using open-access multi-center data.

Functional magnetic resonance imaging (fMRI) of the spinal cord is relevant for studying sensation, movement, and autonomic function. Preprocessing of spinal cord fMRI data involves segmentation of the spinal cord on gradient-echo echo planar imaging (EPI) images. Current automated segmentation methods do not work well on these data, due to the low spatial resolution, susceptibility artifacts causing distortions and signal drop-out, ghosting, and motion-related artifacts.

The Population History of Domestic Sheep Revealed by Paleogenomes.

Sheep was one of the first domesticated animals in Neolithic West Eurasia. The zooarchaeological record suggests that domestication first took place in Southwest Asia, although much remains unresolved about the precise location(s) and timing(s) of earliest domestication, or the post-domestication history of sheep. Here, we present 24 new partial sheep paleogenomes, including a 13,000-year-old Epipaleolithic Central Anatolian wild sheep, as well as 14 domestic sheep from Neolithic Anatolia, two from Neolithic Iran, two from Neolithic Iberia, three from Neolithic France, and one each from Late Neolithic/Bronze Age Baltic and South Russia, in addition to five present-day Central Anatolian Mouflons and two present-day Cyprian Mouflons.

The effects of fumonisin B1 on intercellular communications and miRNA modulations: Non-genotoxic carcinogenesis mechanisms in human kidney cells.

Fumonisin B1 (FB1), which is produced by Fusarium species, is one of the most prevalent mycotoxins known to exert several toxic effects, particularly nephrotoxicity. While its genotoxic carcinogenic mechanisms have been extensively studied, its influence on non-genotoxic pathways including intercellular communication and microRNA (miRNA) regulation remain underexplored. The present study investigates the effects of FB1 on gap junctions, miRNA expression profiles, and their relationship in human kidney cells (HK-2 and HEK293).

Sex and gender considerations in cross-cultural traumatic stress studies.

Following the 1st Conference of the Global Collaboration on Traumatic Stress, the consortium committed to systematically integrating sex and gender considerations in their endeavours, which aligns with the 's Gender Policy. This initiative is vital for understanding trauma's complex impacts, but also presents significant challenges in cross-cultural research. This letter, co-authored by researchers from across the globe, outlines these challenges and proposes mitigation strategies.

Aims: To assess histopathological effects of adipose tissue-derived SVF/gel and nasal steroids on nasal mucosal healing.

Material And Methods: Forty-two Wistar Albino rats with right nasal mucosal injury were randomly divided into three groups: control (saline), Mometasone Furoate (MF), and SVF/gel.

The multistressor effect of pH reduction, microplastic and lanthanum on sea urchin Arbacia lixula.

pH reduction (Low pH), microplastic (MP), and lanthanum (La) are substantial stressors due to their increasing trends in marine ecosystems and having adverse effects on marine species. This study investigates the single and combined effects of those stressors (Low pH: 7.45, polyethylene MP: 26 μg L, and La: 9 μg L) on the physiology and histology of sea urchin Arbacia lixula.

Dual- or single rinse? The tubular sealer penetration of endodontic chelating agents.

Introduction: In this study, we aimed to compare the effectiveness of various chelating agents, ethilenediaminetetraacetic acid (EDTA), citric acid (CA), and etidronic acid (HEDP) mixed in two different forms, in removing the smear layer and promoting the penetration of an endodontic sealer into the dentinal tubules of extracted single-rooted teeth.

Methods: The study used 75 teeth divided into five groups: 17% EDTA, 10% CA, 9% HEDP + NaOCl, 9% HEDP + distilled water (DW), and a control (DW) group. Scanning electron microscopy was used to assess smear layer removal and confocal laser microscopy was used to evaluate tubular sealer penetration at different depths from the apical tip.

Correlation of metal ions with specific brain region volumes in neurodegenerative diseases.

Background/aim: There are reports stating that deteriorations in metal homeostasis in neurodegenerative diseases promote abnormal protein accumulation. In this study, the serum metal levels in Alzheimer's disease (AD) and Parkinson's disease (PD) and its relationship with the cortical regions of the brain were investigated.

Materials And Methods: The patients were divided into 3 groups consisting of the AD group, PD group, and healthy control group (n = 15 for each).

Ancient Sheep Genomes Reveal Four Millennia of North European Short-Tailed Sheep in the Baltic Sea Region.

Sheep are among the earliest domesticated livestock species, with a wide variety of breeds present today. However, it remains unclear how far back this diversity goes, with formal documentation only dating back a few centuries. North European short-tailed (NEST) breeds are often assumed to be among the oldest domestic sheep populations, even thought to represent relicts of the earliest sheep expansions during the Neolithic period reaching Scandinavia <6,000 years ago.

Population Genomic History of the Endangered Anatolian and Cyprian Mouflons in Relation to Worldwide Wild, Feral, and Domestic Sheep Lineages.

Once widespread in their homelands, the Anatolian mouflon (Ovis gmelini anatolica) and the Cyprian mouflon (Ovis gmelini ophion) were driven to near extinction during the 20th century and are currently listed as endangered populations by the International Union for Conservation of Nature. While the exact origins of these lineages remain unclear, they have been suggested to be close relatives of domestic sheep or remnants of proto-domestic sheep. Here, we study whole genome sequences of n = 5 Anatolian mouflons and n = 10 Cyprian mouflons in terms of population history and diversity, comparing them with eight other extant sheep lineages.

Microbial lectins as a potential therapeutics for the prevention of certain human diseases.

Lectins are protein or glycoprotein molecules with a specific ability to bind to carbohydrates. From viruses to mammals, they are found in various organisms and exhibit remarkable diverse structures and functions. They are significant contributors to defense mechanisms against microbial attacks in plants.

An analysis of the relationship of "the Mozart effect" with BDNF levels in anatomy education.

In 1993, an increase was observed in the spatial IQ scores of the volunteers who listened to Mozart's sonata K448 for 10 min, and this phenomenon entered the literature as the "Mozart effect." Other studies have shown that this effect is particularly evident in spatial skill tests. A large body of research has provided evidence that spatial ability is associated with success in learning anatomy.

Recent developments and future avenues for human corticospinal neuroimaging.

Non-invasive neuroimaging serves as a valuable tool for investigating the mechanisms within the central nervous system (CNS) related to somatosensory and motor processing, emotions, memory, cognition, and other functions. Despite the extensive use of brain imaging, spinal cord imaging has received relatively less attention, regardless of its potential to study peripheral communications with the brain and the descending corticospinal systems. To comprehensively understand the neural mechanisms underlying human sensory and motor functions, particularly in pathological conditions, simultaneous examination of neuronal activity in both the brain and spinal cord becomes imperative.

Disulfide bridge-dependent dimerization triggers FGF2 membrane translocation into the extracellular space.

Fibroblast growth factor 2 (FGF2) exits cells by direct translocation across the plasma membrane, a type I pathway of unconventional protein secretion. This process is initiated by phosphatidylinositol-4,5-bisphosphate (PI(4,5)P)-dependent formation of highly dynamic FGF2 oligomers at the inner plasma membrane leaflet, inducing the formation of lipidic membrane pores. Cell surface heparan sulfate chains linked to glypican-1 (GPC1) capture FGF2 at the outer plasma membrane leaflet, completing FGF2 membrane translocation into the extracellular space.

Reliability of task-based fMRI in the dorsal horn of the human spinal cord.

The application of functional magnetic resonance imaging (fMRI) to the human spinal cord is still a relatively small field of research and faces many challenges. Here we aimed to probe the limitations of task-based spinal fMRI at 3T by investigating the reliability of spinal cord blood oxygen level dependent (BOLD) responses to repeated nociceptive stimulation across two consecutive days in 40 healthy volunteers. We assessed the test-retest reliability of subjective ratings, autonomic responses, and spinal cord BOLD responses to short heat pain stimuli (1s duration) using the intraclass correlation coefficient (ICC).
