Aperiodic Pupil Fluctuations at Rest Predict Orienting of Visual Attention.

The aperiodic exponent of the power spectrum of signals in several neuroimaging modalities has been found to be related to the excitation/inhibition balance of the neural system. Leveraging the rich temporal dynamics of resting-state pupil fluctuations, the present study investigated the association between the aperiodic exponent of pupil fluctuations and the neural excitation/inhibition balance in attentional processing. In separate phases, we recorded participants' pupil size during resting state and assessed their attentional orienting using the Posner cueing tasks with different cue validities (i.

Improved Optical Waveguide Microcantilever for Integrated Nanomechanical Sensor.

This paper reports on an improved optical waveguide microcantilever sensor with high sensitivity. To improve the sensitivity, a buffer was introduced into the connection of the input waveguide and optical waveguide cantilever by extending the input waveguide to reduce the coupling loss of the junction. The buffer-associated optical losses were examined for different cantilever thicknesses.

Thinning increases understory diversity and biomass, and improves soil properties without decreasing growth of Chinese fir in southern China.

Sustainable forestry requires adopting more ecosystem-informed perspectives. Tree thinning improves forest productivity by encouraging the development of the understory, which in turn improves species diversity and nutrient cycling, thereby altering the ecophysiological environment of the stand. This study aimed to quantify tree growth, understory vegetation, and soil quality of 9- and 16-year-old Chinese fir (Cunninghamia lanceolata (Lamb.

Comparative Study of Atropine Combined with Sodium Nitroprusside Pretreatment to Prevent Trigemino Cardiac Reflex after Trigeminal Ganglion Compression.

Introduction: Manipulation of percutaneous compression of the trigeminal ganglion (PCTG) for trigeminal neuralgia (TN) can lead to significant haemodynamic changes, which were termed trigemino cardiac reflex (TCR). Nevertheless, many studies indicated that atropine pretreatment can reduce the incidence of bradycardia and cardiac arrest, but do not take precautions against abrupt rise of blood pressure.

Aim: The purpose of our study was to compare control group {patients receiving Sodium Nitro-Prusside (SNP) pretreatment before PCTG} with study groups (patients receiving different doses of atropine combined with SNP pretreatment before PCTG) in cardiovascular parameters {Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP) and Heart Rate (HR)} at 5 periods during Total Intravenous Anaesthesia (TIVA).

Comparative study of trigeminocardiac reflex after trigeminal ganglion compression during total intravenous anesthesia.

Background: Percutaneous compression of the trigeminal ganglion (PCTG) is an alternative surgical treatment for trigeminal neuralgia (TN). Manipulation of PCTG can lead to significant hemodynamic changes, which may increase the risk of cardiovascular complications. However, to our knowledge, few studies have focused on anesthesia experience during PCTG as treatment for TN so far.

Perturbing effects of carvedilol on a model membrane system: role of lipophilicity and chemical structure.

Carvedilol, a beta-adrenergic blocker used to treat cardiovascular diseases, protects cell membranes from lipid peroxidative damage. Previous studies suggested the drug resides in a non-polar environment and partitions into cell membranes, perturbing their fluidity. Here differential scanning calorimetry (DSC) and fluorescence spectroscopy were applied to further investigate interactions of carvedilol with a liposome model.
