Background: The peripheral nervous system (PNS) exhibits remarkable regenerative capability after injury. PNS regeneration relies on neurons themselves as well as a variety of other cell types, including Schwann cells, immune cells, and non-neuronal cells.

Objectives: This paper focuses on summarizing the critical roles of immune cells (SCs) in the injury and repair processes of the PNS.

Article Synopsis
  • China's initiatives to increase public awareness of cervical cancer have led to more HPV diagnoses, with psychological stress affecting both HPV-infected women and their spouses.
  • A study conducted with 11 couples revealed themes around stress perception, communication, and adjustment in coping with HPV.
  • The findings suggest that healthcare professionals should support couples in managing their stress together and improve their coping strategies as a partnership.

Fenitrothion (FNT) is a common organophosphorus pesticide that is widely used in both agricultural and domestic pest control. FNT has been frequently detected in various environmental media, including the human body, and is a notable contaminant. Epidemiological investigations have recently shown the implications of exposure to FNT in the incidence of various metabolic diseases, such as diabetes mellitus in humans, indicating that FNT may be a potential endocrine disruptor.

Snake gourd is a seasonal vegetable with a high water content and medicinal value, but the short harvest period limits the large-scale application of snake gourd. Therefore, the effects of freeze-thaw pretreatment (FT) combined with hot air (HD) on the drying characteristics, active ingredients and bioactivities of snake gourd were investigated. The results showed that FT pretreatment reduced browning and shortened the drying time by 44%; the Page model was the best fit for describing the drying process.

Nerve injury is a common condition that occurs as a result of trauma, iatrogenic injury, or long-lasting stimulation. Unlike the central nervous system (CNS), the peripheral nervous system (PNS) has a strong capacity for self-repair and regeneration. Peripheral nerve injury results in the degeneration of distal axons and myelin sheaths.

  • Acrylamide (ACR) is a harmful food contaminant found in many foods, raising health concerns, particularly regarding its impact on insulin-resistant cells.
  • The study created a model using BRL cells to investigate how insulin resistance affects the cells' response to different concentrations of ACR, finding that exposure decreased glucose uptake and increased fat levels, aggravating metabolic disorders.
  • Results indicated that ACR exposure heightened the activation of stress and apoptosis pathways in insulin-resistant BRL cells, suggesting that ACR is more toxic to cells that already have insulin resistance due to enhanced endoplasmic reticulum stress.

Article Synopsis
  • - The study investigates how Fas-L affects the repair and regeneration of peripheral nerve injuries in rats, specifically looking at its role in neuronal cell apoptosis and axonal regeneration.
  • - Results show that Fas-L levels decrease after sciatic nerve injury, and manipulating Fas-L expression can either promote axon regeneration and reduce cell death or inhibit these processes, depending on whether it is increased or decreased.
  • - The findings suggest that Fas-L plays a significant role in regulating dorsal root ganglion function and peripheral nerve repair by influencing various signaling pathways, which could provide insights for better approaches in nerve injury treatment.

Although efficiency analysis could reflect the state and quality of tourism's economic development, no research has been conducted investigating the spatiotemporal evolution and mechanisms of county-level tourism efficiency. We quantified tourism efficiency and its decomposition in 63 counties of Zhejiang, employing the bootstrap data envelopment analysis (DEA), hot spot analysis, and quantile regression to explore the spatiotemporal evolution and influencing factors of tourism efficiency, and examine its driving and constraining mechanisms. The results uncovered obvious upward trends in the tourism efficiency of Zhejiang's counties, with the mean value increasing from 0.

Injuries caused by trauma and neurodegenerative diseases can damage the peripheral nervous system and cause functional deficits. Unlike in the central nervous system, damaged axons in peripheral nerves can be induced to regenerate in response to intrinsic cues after reprogramming or in a growth-promoting microenvironment created by Schwann cells. However, axon regeneration and repair do not automatically result in the restoration of function, which is the ultimate therapeutic goal but also a major clinical challenge.

Accurate hyperspectral remote sensing information is essential for feature identification and detection. Nevertheless, the hyperspectral imaging mechanism poses challenges in balancing the trade-off between spatial and spectral resolution. Hardware improvements are cost-intensive and depend on strict environmental conditions and extra equipment.

A novel, to the best of our knowledge, gallium nitride (GaN)-based resonant cavity light-emitting diode (RCLED) with single-longitudinal-mode light emission was demonstrated. A TaO/SiO dielectric distributed Bragg reflector (DBR) with a filter-film structure was adopted as the top mirror. In contrast to the flat-topped reflectivity spectrum of the conventional high-reflective-structure DBR, for this filter-film-structure DBR, there is a light-transmitting concave band on the reflectivity spectrum.

Article Synopsis
  • Silicon films are highly effective anode materials for lithium batteries due to their high capacity, but their practical use is hindered by significant volume expansion and unstable solid electrolyte interphase (SEI) issues.
  • Coating silicon nanocolumns with lithium fluoride (LiF) via glancing angle evaporation helps improve lithium ion diffusion and stabilizes the SEI, addressing the key challenges.
  • The LiF-coated silicon nanocolumns demonstrate better performance, including enhanced rate capability and cycling stability compared to uncoated silicon, showcasing the benefits of this coating approach.

The emergence of DNA origami greatly accelerated the development of DNA nanotechnology. A thorough understanding of origami thermodynamics is very important for both fundamental studies and practical applications. These thermodynamic transitions usually take place in several seconds or even less, and are very difficult to monitor by conventional methods.

Leaves are essential organs for plants. We previously identified a functional gene possibly encoding a component of the SWI/SNF complex named Leaf and Flower Related (LFR) in Arabidopsis thaliana. Loss-of-function mutants of LFR displayed obvious defects in leaf morphogenesis, indicating its vital role in leaf development.

Excitotoxicity plays an important role in neuronal loss in glaucoma. Previous studies indicate melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) are more injury-resistant. However, whether melanopsin-expressing ipRGCs are resistant to N-methyl-d-aspartate (NMDA) induced excitotoxicity is not well understood.

Specification of distinct cell types from Müller glial cells is key to the potential application of endogenous repair in retinal regeneration. Sonic hedgehog (SHH) has been established as a potent mitogen for rat Müller glial cells, which also induces Müller glial cells to dedifferentiate and adopt the phenotype of rod photoreceptors. The present study investigated the effects of purmorphamine, a small molecule that activates the SHH‑pathway, in the proliferation, dedifferentiation and transdifferentiation of Müller glial cells, as determined by several methods including immunofluorescence, polymerase chain reaction and western blotting.
