Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Multi-level assessment of soil quality – linking reductionistic and holistic methodologies [PDF]

open access: yes, 2000
Soil quality is often used as a qualitative, general term. However, quantification is an important feature of the scientific approach to nature. On the other hand, addressing specific soil parameters as indicators of soil quality includes a reduction of ...

Case study on low-frequency time-code signal during the 10–15 November 2025 geomagnetic storm: observations and analysis

open access: yesFrontiers in Astronomy and Space Sciences
IntroductionGeomagnetic storms are typical solar eruption activities. When high-speed solar wind or coronal mass ejections from solar eruptions strike the Earth, they trigger rapid severe geomagnetic disturbances and further induce ionospheric variations.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

open access: yesFEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Reasearch and evaluation of electromagnetic fields of refrigerators / Šaldytuvų elektromagnetinių laukų tyrimai ir vertinimas

open access: yesMokslas: Lietuvos Ateitis, 2013
The use of refrigerators causes the occurence of electromagnetic fields that are invisible and intangible, which therefore makes difficulties in protecting ourselves from them. A refrigerator is an irreplaceable item in domestic household and thus can be

Exploring the influence of lactoferrin on wound healing and related signaling pathways: a systematic review

open access: yesFEBS Open Bio, EarlyView.
Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.

Test and Analysis of the Influence of Lake Water Obstacle on the Near-field Timing Signal of BPC

open access: yesMeasurement Science Review
The lake water environment is a common and complex scenario for the application of radio time synchronization. When the timing signal enters lake water, signal strength attenuation and phase shift occur, which greatly affect time service performance.
