C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Variables posturométricas en pacientes desdentados totales con rehabilitación protésica

open access: yesRevista Información Científica
Introducción: en los pacientes que han perdido todos sus dientes, el reborde alveolar residual tiende a experimentar una mayor reabsorción. Esto hace necesario llevar a cabo una rehabilitación oclusal que sea lo más fisiológica posible y considerar entre

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Digital Photo Analysis as a Predictor of Physiological Vertical Dimension

open access: yesJournal of Dentistry Indonesia, 2013
Determination of the vertical dimension is based on patient's resting jaw position, which is the physiological vertical dimension. Objective: To examine the accuracy of physiological vertical dimension using digital photography. Methods: The research was

Forward Modeling and Model Test of Ground-Penetrating Radar toward Typical Asphalt Pavement Distresses

open access: yesAdvances in Civil Engineering, 2023
As the total mileage of roads with asphalt concrete pavement is increasing rapidly, using ground-penetrating radar (GPR) to estimate the dimension of internal distresses of the asphalt pavement is of great significance for pavement maintenance.

Lo Sagrado y la Memoria: hacia una teoría sociológica de la religión [PDF]

open access: yes, 2014
En este artículo hemos tratado de mostrar, desde una perspectiva teórica, los desarrollos y las transformaciones acaecidas, durante las últimas décadas, en dos sistemas de creencias distintos: la filosofía y, especialmente, la religión.

Intraband absorption for normal illumination in quantum dot intermediate band solar cells [PDF]

open access: yes, 2010
In the current intermediate band solar cells made with InAs quantum dots (QDs) in GaAs, the transitions by absorption of photons between the intermediate band and the conduction band for illumination normal to the cell surface is very weak or, more often,

ALS With and Without Upper Motor Neuron Signs: A Comparative Study Supporting the Gold Coast Criteria

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The Gold Coast criteria permit diagnosis of amyotrophic lateral sclerosis (ALS) even without upper motor neuron (UMN) signs. However, whether ALS patients with UMN signs (ALSwUMN) and those without (ALSwoUMN) share similar characteristics and prognoses remains unclear.
