(p<0.005) and (B) BOLD changes (p<0.005) during right hand movement displayed on an inflated cortical surface with white arrow indicating the central sulcus. (C) shows the locations of peak BOLD changes and time course of BOLD percentage change derived from these two regions (baseline is from -4 s to 0 s). ACCOMPANYING EVENT-RELATED DECREASE OF ALPHA BAND EEG AND SUSTAINED NEGATIVE BOLD RESPONS...

Journal: :F1000Research 2023

Background: Percutaneous nephrolithotomy (PCNL) is the preferred treatment for removal of large kidney stones, sized &gt;20 mm. However, there still an ongoing debate concerning best anesthesia PCNL. This study aimed to compare efficacy and safety between general spinal PCNL. Methods: A systematic review meta-analysis study.<ns4:bo...

Background: Cholangiocarcinoma (CCA) incidence in Northeastern Thailand is very high and a major cause of mortality. CCA patients typically have poor prognosis short-term survival rate due to late-stage diagnosis. the first Southeast Asian country approve medicinal cannabis treatment, especially for palliative care with advanced cancer patients.<...

Background: The exponential increase in pattern of vehicles on the roads demands a need to develop vehicular infrastructure that may not only ease congestions and provide better experience but also pivot levels safety among users. The development wireless technology has made it convenient for machines, devices interact with one another. efficacy ...

Journal: :F1000Research 2023

Background: We report the clinical outcomes, operational and training model from first diagnostic interventional nephrology (DIN) department in a UK renal unit. Methods: Patient outcomes were evaluated for an array of therapeutic procedures performed at DIN unit, SDIN (the Sunderland Diagnostic Intervention Unit), within year its ...

A fluorescent hydroxyl- and hydrazone-based covalent organic framework (TFPB–DHTH COF) was synthesized as an “OFF–ON” sensor for cysteine l-histidine.

Journal: :F1000Research 2022

Background: Among individuals with vestibular dysfunction, the loss of vestibular sensory information is found to alter cognitive abilities that coordinate spatial and non-spatial information. P300 an event-related potential commonly used assess processing. The aim present stu...

The blood oxygenation level-dependent (BOLD) response has been strongly associated with neuronal activity in the brain. However, some neuronal tuning properties are consistently different from the BOLD response. We studied the spatial extent of neural and hemodynamic responses in the primary visual cortex, where the BOLD responses spread and interact over much longer distances than the small re...

We compare fMRI-BOLD responses in anesthetized cats with local field potentials (LFPs), aggregate high-frequency responses (analog-Mua) and spiking activity recorded in primary and higher visual cortex of alert animals. The similarity of the activations in these electrophysiological signals to those in the BOLD is quantified by counting recording sites where different stimuli elicit the same re...
