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 ...

Prognostic Value of an Early Response to Tolvaptan and Its Clinical Implications in Patients With Cirrhosis and Hepatic Edema: A Nationwide Multicenter Cohort Study

open access: yesHepatology Research, EarlyView.
In a nationwide multicenter cohort, an early response to tolvaptan (≥ 1.5‐kg weight loss within 7 days) was independently associated with improved long‐term survival in patients with cirrhosis and hepatic edema. Early initiation before renal impairment or hyponatremia may optimize treatment response and prognosis. ABSTRACT Aim Hepatic edema indicates a

The Roles of Vocabulary Size, Word Part Knowledge, and Semantic Transparency in Vocabulary Learning Through the Word Part Technique

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study investigated the influence of learner‐ and word‐related variables on L2 vocabulary learning through the word part technique (WPT), a morphological mnemonic designed to strengthen form–meaning associations through knowledge of affixes and stems.
