H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

open access: yesThe FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Dental Factors Associated With Oropharyngeal Dysphagia in Institutionalised Older Adults: A Systematic Review

open access: yesGerodontology, EarlyView.
ABSTRACT Background Aging is associated with a decline in physiological functions. Dysphagia, a disorder among older adults, impairs feeding and is related to morphological and functional changes in the stomatognathic system, which worsen with age‐related physiological decline, particularly among institutionalised older adults.

Prediction of organic acid concentration in BRS Capiaçu elephant grass silage

open access: yesGrassland Science, EarlyView.
Abstract This study aimed to develop prediction models for organic acid concentrations in Capiaçu grass (Pennisetum purpureum Schum) silage, based on fermentation parameters and chemical composition. Data were obtained from an experiment that evaluated BRS (Brazil Seeds) Capiaçu grass silage with the inclusion of dehydrated cashew pseudofruit ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...
