The Impairment of Body Condition Transiently Increases Oxidative Stress: A Dietary Restriction Experiment in Partridges

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT A proper body condition determines the correct functioning of physiological processes and the optimal expression of fitness‐related traits. Among these processes, maintaining the redox balance is essential to protect the organism from damage caused by oxidative stress.

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Systematic in‐hospital screening and treatment for osteoporosis in a geriatric population with hip fractures

Journal of Hospital Medicine, EarlyView.
Abstract Background Low‐trauma fractures of the hip signify osteoporosis and increase the risk of a second fracture. However, screening for secondary osteoporosis and initiating osteoporosis treatment can be challenging in a geriatric population.

Optimal Power Distribution Control for Multicode MC-CDMA with Zero-Forcing Successive Interference Cancellation

EURASIP Journal on Advances in Signal Processing, 2005
Multicarrier CDMA (MC-CDMA) has become a promising candidate for future wireless multimedia communications for its robustness to frequency-selective fading and its flexibility for handling multiple data rates.

Improved and Automated Detection of Papillary Muscle Infarction Using Joint Bright‐ and Black‐Blood Late Gadolinium Enhancement MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Papillary muscle infarction (PMI) has been linked to significantly increased mortality and is associated with ventricular arrhythmias and mitral regurgitation. Reference bright‐blood late gadolinium enhancement (LGE) imaging provides poor scar‐to‐blood contrast, making PMI visualization challenging. Black‐blood LGE imaging overcomes

Optimized Long‐TE 1H sLASER MR Spectroscopic Imaging at 3T for Separate Quantification of Glutamate and Glutamine in Glioma

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Glutamate and glutamine are critical metabolites in gliomas, each serving distinct roles in tumor biology. Separate quantification of these metabolites using in vivo MR spectroscopy (MRS) at clinical field strengths (≤ 3T) is hindered by their molecular similarity, resulting in overlapping, hence indistinguishable, spectral peaks ...
