This systematic review and meta-analysis evaluated the impact of intraoperative epidural steroid-soaked gelatin sponge in lumbar spine surgery for conditions like spinal stenosis and nerve root compression. Surgery often involves removing structures to decompress the nerves. Steroids are used to alleviate inflammation and pain, with gelatin sponges serving as carriers to extend their effect.

The accumulation of Cd by rice poses significant health risks. Foliar fertilization with Zn can reduce grain Cd contents in rice grown in Cd-contaminated soils. However, atmospheric deposition on leaves is another vector of Cd contamination, and it remains unclear how Zn application affects the allocation of such Cd.

Article Synopsis
  • Modern humans have seen rapid population growth recently, potentially due to relaxed selective pressures from increased food availability since the Last Glacial Maximum.* -
  • A study analyzed mitochondrial DNA from 26,419 East Eurasian genomes, finding higher N/S ratios in populations that expanded, suggesting weaker purifying selection and retention of mildly harmful mutations.* -
  • These findings imply that the expanded populations faced less selective pressure, allowing for the accumulation of mutations that could influence current health and disease trends.*

  • * In a study of 2,877 Han Chinese individuals, haplogroup M7 was identified as significantly linked to lower body mass index, waist circumference, and waist-to-hip ratio, making it a potential factor in reduced obesity risk.
  • * Among the M7 haplogroup, the subhaplogroup M7b1a1 was highlighted as most associated with lower obesity risk, and specific mutations in it could impact mitochondrial function, with additional interactions noted with certain nuclear variants.

Studying language evolution brings a crucial perspective to bear on questions of human prehistory. As the most linguistically diverse region on earth, East and Southeast Asia have witnessed extensive sociocultural and ethnic contacts among different language communities. Especially, the Kra-Dai language family exhibits tremendous socio-cultural importance in these regions.

Synchrotron-based micro-X-ray fluorescence analysis (µXRF) is a nondestructive and highly sensitive technique. However, element mapping of rare earth elements (REEs) under standard conditions requires care, since energy-dispersive detectors are not able to differentiate accurately between REEs L-shell X-ray emission lines overlapping with K-shell X-ray emission lines of common transition elements of high concentrations. We aim to test REE element mapping with high-energy interference-free excitation of the REE K-lines on hyperaccumulator plant tissues and compare with measurements with REE L-shell excitation at the microprobe experiment of beamline P06 (PETRA III, DESY).

Rare earth elements (REEs) are critical for numerous modern technologies, and demand is increasing globally; however, production steps are resource-intensive and environmentally damaging. Some plant species are able to hyperaccumulate REEs, and understanding the biology behind this phenomenon could play a pivotal role in developing more environmentally friendly REE recovery technologies. Here, we identified a REE transporter NRAMP REE Transporter 1 (NREET1) from the REE hyperaccumulator fern .

Dicranopteris linearis is the best-known hyperaccumulator species of rare earth elements (REEs) and silicon (Si), capable of dealing with toxic level of REEs. Hence, this study aimed to clarify how D. linearis leaves cope with excessive REE stress, and whether Si plays a role in REE detoxification.

Salt stress is one of the major causes of reduced crop production, limiting agricultural development globally. Plants have evolved with complex systems to maintain the balance between growth and stress responses, where signaling pathways such as hormone signaling play key roles. Recent studies revealed that hormones are modulated by microRNAs (miRNAs).

  • Efforts to restore degraded mine lands face challenges due to unclear drivers of biodiversity recovery and ecosystem function.
  • Plant-soil feedbacks (PSFs) play a crucial role in shaping vegetation and community structure, but mining disturbances create unique conditions that require special consideration.
  • Understanding PSFs can help predict and improve ecosystem recovery, but further research is needed to address existing challenges in this field.

The exploitation of ion-adsorption rare earth element (REE) deposits in South China has left large areas of mine tailings. However, limited remediation practices on these tailings have been reported, and how the remediation strategies and economic plants cultivation affect the biogeochemical cycles of nutrients, REEs and Al remains unclear. The aim of the present study was to investigate the effects of the combination of the addition of soil amendment and the root development and activity of a fiber plant ramie (Boehmeria nivea L.

Article Synopsis
  • Organic acids play a key role in the tolerance, uptake, and translocation of rare earth elements (REE) in hyperaccumulators like Phytolacca americana, although the mechanisms are not well understood.
  • This study is the first to illustrate how P. americana enhances REE tolerance and accumulation through the secretion of organic acids from its roots, particularly highlighting the effect of yttrium (Y) on oxalate secretion.
  • The research showed that while oxalate secretion does not prevent Y uptake, it leads to increased levels of malate and citrate, which aid in redistributing Y from roots to shoots, suggesting a complex mechanism of detoxification and transport involving specific transport proteins.

The population prehistory of Xinjiang has been a hot topic among geneticists, linguists, and archaeologists. Current ancient DNA studies in Xinjiang exclusively suggest an admixture model for the populations in Xinjiang since the early Bronze Age. However, almost all of these studies focused on the northern and eastern parts of Xinjiang; the prehistoric demographic processes that occurred in western Xinjiang have been seldomly reported.

The molecular mechanism of the maintenance and differentiation of plant stem cells is an eternal theme in studies on plant growth and development. Recent advances in single-cell RNA sequencing (scRNA-seq) methods have completely changed the understanding of cell heterogeneity and cell function, allowing research precision to identify the differentiation trajectory of stem cells maintained and differentiated at the cellular level. This review aimed to mainly discuss the novel insights provided by scRNA-seq for the maintenance and initiation of plant stem cells, cell differentiation, cell response to environmental changes, and improvement strategies for scRNA-seq.

The expansion of anatomically modern humans (AMHs) from Africa around 65,000 to 45,000 y ago (ca. 65 to 45 ka) led to the establishment of present-day non-African populations. Some paleoanthropologists have argued that fossil discoveries from Huanglong, Zhiren, Luna, and Fuyan caves in southern China indicate one or more prior dispersals, perhaps as early as ca.

The Fujian Tanka people are officially classified as a southern Han ethnic group, whereas they have customs similar to Daic and Austronesion people. Whether they originated in Han or Daic people, there is no consensus. Three hypotheses have been proposed to explain the origin of this group: (1) the Han Chinese origin, (2) the ancient Daic origin, (3) and the admixture between Daic and Han.

Injury severity is correlated with poor prognosis after traumatic brain injury (TBI). It is not known whether triglycerides (TGs) or total cholesterol (TC) is good biomarker of increased injury of neuroinflammation and apoptosis in a high fat diet (HFD)-treated rat after TBI episodes. Five-week-old male Sprague-Dawley (SD) rats were fed a HFD for 8 weeks.

Background: Pregnancy is a known risk factor for spontaneous spinal epidural hematoma. During cesarean section or vaginal delivery, the unstable hemodynamic status that may occur owing to fluctuation of intra-abdominal pressure increases the possibility of spontaneous spinal epidural hematoma. During labor and the postpartum period, neurologic symptoms may be masked by labor pain or anesthesia block, which makes early diagnosis difficult, especially in the obstetric clinic without a neurologist or neurosurgeon.
