Ultrasonic doppler flowmeter-guided occipital nerve block [PDF]

, 2010
BACKGROUND: Greater occipital nerve block is used in the treatment of headaches and neuralgia in the occipital area. We evaluated the efficacy of ultrasonic doppler flowmeter-guided occipital nerve block in patients experiencing headache in the occipital

Stability and Performance of Sn–Zn/C versus Sn–Cu/C Bimetallic Catalysts for Electrochemical Formic Acid Production Under Realistic Diluted Feed Conditions

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Beyond Pure CO2: Sn–Zn/C and Sn–Cu/C show comparable formic acid production under pure CO2 (40.81% vs. 29.17% FE), but only Sn–Zn/C maintains activity under realistic 50% CO2 dilution (42.7% retention) while Sn–Cu/C fails completely. Multimodal characterization reveals that thermodynamic oxide phase compatibility and textural stability are critical ...

Long‐term effects of moderate and severe hypoxia on growth, intermediary metabolism, monoamine neurotransmitters, and fatty acids in juveniles of coho salmon, Oncorhynchus kisutch

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Hypoxia concerns have increased in recent decades, reducing fish fitness and becoming a critical challenge in salmon aquaculture. We investigated the effect of long‐term hypoxia on the physiological response of coho salmon (Oncorhynchus kisutch).

Combined multi‐metric assessment of diaphragm contractile function in healthy humans: Feasibility, validity and reliability

Experimental Physiology, Volume 111, Issue 4, Page 2308-2323, 1 April 2026.
Abstract The combined use of subcostal ultrasonography and respiratory manometry represents a novel, integrative method for quantifying diaphragm contractile function (force, velocity and power). We evaluated the technical feasibility, construct validity and within‐day test–retest reliability of this method during non‐volitional, volitional and ...

Ultrasonic flowmeter setup.

, 2013
Molar mass was measured in a sidestream ultrasonic flowmeter (USFM) and flow was measured in a mainstream USFM. Oxygen (O2), and carbon dioxide (CO2) were measured in sidestream sensors.

Cardiovascular, respiratory and splenic responses to rebreathing and apnoea during exercise

Experimental Physiology, Volume 111, Issue 4, Page 1971-1987, 1 April 2026.
Abstract We investigated integrative physiological responses to eupnoeic exercise (EX), rebreathing exercise (RB), dynamic apnoea (DA) and dynamic apnoea with cold‐water face immersion (DAFI) in 20 healthy participants. Trials involved non‐steady‐state cycle exercise at 60 W for an average duration of 66 s.
