Factors Influencing Acceptance of Microalgae-Based Iron Supplements in Romanian Adults With Self-Reported Iron-Deficiency Anemia: A Cross-Sectional Study. [PDF]

Anemia
Microalgae‐derived iron preparations are entering clinical discourse as a potentially better‐tolerated alternative to conventional ferrous salt supplementation, which fails a substantial proportion of the approximately 571 million women globally affected by iron‐deficiency anemia (IDA) due to gastrointestinal adverse effects.

Pregabalin contributes to increased recovery time from isoflurane anaesthesia for magnetic resonance imaging in horses. [PDF]

Equine Vet J
Abstract Background Pregabalin reduces excitatory neurotransmitter release and is used for anxiolysis in humans, cats, and horses. The effects of pregabalin on equine recovery following isoflurane anaesthesia are unknown. Objectives To determine if pre‐anaesthetic oral pregabalin influences recovery time and/or quality from isoflurane anaesthesia in ...

Outcome of Liver Retransplantation in Patients With Primary Sclerosing Cholangitis. [PDF]

Liver Int
ABSTRACT Background and Aims Primary sclerosing cholangitis (PSC) is among the most common indications for liver transplantation in the Nordic countries and with an increasing trend in Europe and North America. Due to post‐transplant complications and high prevalence of disease recurrence this group is at risk of requiring retransplantation (re‐LTX ...

An Improved Passivity-based Control of Electrostatic MEMS Device [PDF]

Micromachines, 2020
It is commonly known that the performance of an electrostatic microelectromechanical system (MEMS) device is limited to a specific range of the full gap distance due to the inherited “pull-in instability” phenomenon.

Robust interconnection and damping assignment energy-based control for a permanent magnet synchronous motor using high order sliding mode approach and nonlinear observer

Energy Reports, 2022
Several advantages are provided by the permanent magnet synchronous motor (PMSM) over DC motors and is gradually replacing them in industry. The dynamics of the PMSM can be described by time-varying non-linear equations considering unknown external ...

Interconnection and damping assignment passivity-based non-linear observer control for efficiency maximization of permanent magnet synchronous motor

Energy Reports, 2022
The permanent magnet synchronous motor (PMSM) has several advantages over the DC motor and is gradually replacing it in the industry. The dynamics of the PMSM are described by non-linear equations; it is sensitive to unknown external disturbances (load),
