6. A Highly Water‐ and Air‐Stable Iron‐Containing MRI Contrast Agent Sensor for H2O2.

Abstract

A highly water‐ and air‐stable Fe(II) complex with the quinol‐containing macrocyclic ligand H4qp4 reacts with H2O2 to yield Fe(III) complexes with less highly chelating forms of the ligand that have either one or two para‐quinones. The reaction increases the T1‐weighted relaxivity over four‐fold, enabling the complex to detect H2O2 using clinical MRI technology. The iron‐containing sensor differs from its recently characterized manganese analog, which also detects H2O2, in that it is the oxidation of the metal center, rather than the ligand, that primarily enhances the relaxivity.

8. Hip thrust and back squat training elicit similar gluteus muscle hypertrophy and transfer similarly to the deadlift.

Abstract

Purpose: We examined how set-volume equated resistance training using either the back squat (SQ) or hip thrust (HT) affected hypertrophy and various strength outcomes., Methods: Untrained college-aged participants were randomized into HT or SQ groups. Surface electromyograms (sEMG) from the right gluteus maximus and medius muscles were obtained during the first training session. Participants completed nine weeks of supervised training (15-17 sessions), before and after which we assessed muscle cross-sectional area (mCSA) via magnetic resonance imaging and strength via three-repetition maximum (3RM) testing and an isometric wall push test., Results: Glutei mCSA growth was similar across both groups. Estimates [(-) favors HT; (+) favors SQ] modestly favored the HT compared to SQ for lower [effect ± SE, -1.6 ± 2.1 cm 2 ], mid [-0.5± 1.7 cm 2 ], and upper [-0.5 ± 2.6 cm 2 ], but with appreciable variance. Gluteus medius+minimus [-1.8 ± 1.5 cm 2 ] and hamstrings [0.1 ± 0.6 cm 2 ] mCSA demonstrated little to no growth with small differences between groups. Thigh mCSA changes were greater in SQ for the quadriceps [3.6 ± 1.5 cm 2 ] and adductors [2.5 ± 0.7 cm 2 ]. Squat 3RM increases favored SQ [14 ± 2.5 kg] and hip thrust 3RM favored HT [-26 ± 5 kg]. 3RM deadlift [0 ± 2 kg] and wall push strength [-7 ± 13 N] similarly improved. All measured gluteal sites showed greater mean sEMG amplitudes during the first bout hip thrust versus squat set, but this did not consistently predict gluteal hypertrophy outcomes., Conclusion: Nine weeks of squat versus hip thrust training elicited similar gluteal hypertrophy, greater thigh hypertrophy in SQ, strength increases that favored exercise allocation, and similar strength transfers to the deadlift and wall push.

Abstract

A highly water- and air-stable Fe(II) complex with the quinol-containing macrocyclic ligand H 4 qp4 reacts with H 2 O 2 to yield Fe(III) complexes with less highly chelating forms of the ligand that have either one or two para-quinones. The reaction increases the T 1 -weighted relaxivity over four-fold, enabling the complex to detect H 2 O 2 using clinical MRI technology. The iron-containing sensor differs from its recently characterized manganese analog, which also detects H 2 O 2 , in that it is the oxidation of the metal center, rather than the ligand, that primarily enhances the relaxivity., (© 2022 Wiley-VCH GmbH.)
