A critical assessment of possible pitfalls in absolute configuration assignment using Vibrational Circular Dichroism
Vibrational Circular Dichroism (VCD) is no longuer a curious novelty in the field of molecular spectroscopy as VCD spectrometers are commercially available as well as the algorithms to calculate the spectra, which are implemented in various software packages. This makes VCD routinely applicable for …

Finite-Difference and Analytic-Gradient Approaches for Simulating Vibrational Circular Dichroism Using Second-Order Møller-Plesset Perturbation Theory and Configuration Interaction
Vibrational circular dichroism (VCD) is defined as the differential absorption of left- and right-circularly polarized light in the infrared region of the electromagnetic spectrum. Application of this spectroscopy is primarily directed towards the elucidation of molecular absolute configuration. As …

Characterization of Residual Ovarian Tissue in Mice following 4-vinylcyclohexene Diepoxide-induced Ovarian Failure
… of these disorders. The present studies used the VCD-treated follicle-depleted mouse model of menopause to test the hypothesis that residual ovarian tissue retains steroidogenic capacity following ovarian failure and, thus, affects the development of these disorders. Microarray technology was used …

Biocapacitance Sensors for In-Line Viable Cell Density Monitoring in Complex Bioreactors
The precise monitoring of Viable Cell Density (VCD) in bioreactors is crucial for optimizing bioprocesses, improving yield, and maintaining product quality. VCD can be effectively indicated by biocapacitance, a capacitance associated with the viable cell membrane, which can be detected through …

The Neuroprotective Effects of Exercise Against Menopause Induced Alterations in Alzheimer’s Disease Neuropathogenesis
… the oil vehicle or 4-vinylcyclohexene diepoxide (VCD) to induce gradual ovarian failure. All mice were given pre- and post-cardiovascular tests at two timepoints, to assess the effects of exercise or being sedentary for 12 weeks. All 24 WoA mice remained sedentary throughout the study. Half of the …
