Chemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022 Structural and biochemical data demonstrate that 4‐phenylbenzoic acid binds within the active site of the cytochrome P450 monooxygenase CYP199A4, but no oxidation occurs. Protein engineering and molecular dynamic simulations establish that aromatic oxidation is enabled by a subtle shift of the substrate relative to the heme, thus improving our ...

Influence of Valine Analogues on Protein Synthesis of Chicken Embryo Myoblasts
The Journal of Poultry Science, 2014 The influence of various valine analogues on protein synthesis of chicken embryo myoblasts was examined. Valine and its analogues (D-valine, methylvaline, valinol) were supplemented into Medium 199 containing 20 ng/ml of chicken insulin-like growth ...

Interference-Normalised Least Mean Square Algorithm [PDF]
IEEE Signal Processing Letters, Vol. 14, No 12, pp. 988-991, 2007, 2016 An interference-normalised least mean square (INLMS) algorithm for robust adaptive filtering is proposed. The INLMS algorithm extends the gradient-adaptive learning rate approach to the case where the signals are non-stationary. In particular, we show that the INLMS algorithm can work even for highly non-stationary interference signals, where previous ...

Bandwidth Extension of Narrowband Speech for Low Bit-Rate Wideband Coding [PDF]
Proc. IEEE Speech Coding Workshop (SCW), 2000, pp. 130-132, 2016 Wireless telephone speech is usually limited to the 300-3400 Hz band, which reduces its quality. There is thus a growing demand for wideband speech systems that transmit from 50 Hz to 8000 Hz. This paper presents an algorithm to generate wideband speech from narrowband speech using as low as 500 bits/s of side information.

Branched-chain amino acids linked to depression in young adults
Frontiers in Neuroscience, 2022 Depression is a heterogeneous mental health problem affecting millions worldwide, but a majority of individuals with depression do not experience relief from initial treatments. Therefore, we need to improve our understanding of the biology of depression.

Perceptually-Motivated Nonlinear Channel Decorrelation For Stereo Acoustic Echo Cancellation [PDF]
Proceedings of Joint Workshop on Hands-free Speech Communication
and Microphone Arrays (HSCMA), pp. 188-191, 2008, 2016 Acoustic echo cancellation with stereo signals is generally an under-determined problem because of the high coherence between the left and right channels. In this paper, we present a novel method of significantly reducing inter-channel coherence without affecting the audio quality.

Targeting HIBCH to reprogram valine metabolism for the treatment of colorectal cancer
Cell Death and Disease, 2019 Valine catabolism is known to be essential for cancer cells but the detailed mechanism remains unclear. This study is to explore the critical roles of 3-hydroxyisobutyryl-CoA hydrolase (HIBCH) in colorectal cancers (CRC) and to develop a new therapy ...
