Summary: The proportion of methane explosion accidents in coal mine production accidents has been increasing in recent years. A D-shaped PCF methane gas sensor based on SPR was proposed in this study to address the difficulty of filling methane gas into the inner air holes in PCFs. Simulation results showed that the designed sensor achieved a measurement sensitivity of 9.88 nm/% at methane concentrations of 0%-3.5%, with a linearity of 99.8%. The sensor is considered a candidate for methane gas leakage detection due to its simplicity and feasibility.

Summary: A dual-channel sensor for refractive index (RI) and temperature measurement was proposed by modifying the gap on the D-shaped surface of a photonic crystal fiber. The sensing performance for RI was improved by applying Ag films based on surface plasmon resonance (SPR) effect, while the temperature channel was enhanced by overlaying a PDMS film. Additionally, a TiO2 film was introduced to protect the Ag film from oxidation and optimize the sensing performance. The highest sensitivities of RI and temperature, achieved with an Ag film thickness of 45 nm and a TiO2 film thickness of 13 nm, were 6700 nm/RIU and -21 nm/degrees C respectively.

Summary: This paper proposes a D-type highly sensitive surface plasmon resonance (SPR) sensor based on multilayer films coated with photonic crystal fiber (PCF). Silver is chosen as the plasmon material due to its sharper SPR spectrum compared to gold. Additionally, titania (TiO2) is used as the second layer film to prevent silver oxidation and enhance the SPR effect. The refractive index sensing performances are simulated using the finite element method (FEM). The optimized multilayer film structure shows a significant improvement in the wavelength sensitivity of the sensor, with a maximum sensitivity of 11,000 nm/RIU, an increase of 139% compared to a single silver film. The high sensitivity and figure of merit (FOM) of this sensor make it suitable for accurately detecting medical treatments and organic chemicals.

Summary: The objective of this study was to analyze the value of serum miRNA-122 expression in the diagnosis, severity, and prognosis of Acute Cerebral Infarction (ACI), as well as the correlation mechanism of serum miRNA-122 on the proliferation and apoptosis of vascular endothelial cells in ACI. The results showed that serum miRNA-122 expression in patients with ACI was significantly higher than that in healthy controls, indicating its potential as a diagnostic marker for ACI. Furthermore, miRNA-122 may regulate ACI by inhibiting cell proliferation, increasing apoptosis, and inhibiting vascular endothelial cell regeneration through the CCNG1 channel.
