Objective: Creak is an acoustic feature found to discriminate speakers with adductor laryngeal dystonia (AdLD) from typical speakers with outstanding diagnostic accuracy. Yet creak is also used by typical speakers as a phrase-boundary marker. This study aims to compare the prevalence of creak across estimated breath groups in speakers with AdLD and controls to delineate physiological mechanisms underlying creak in AdLD.

Article Synopsis
  • Understanding pork tenderness and quality is complicated due to insufficient knowledge of the molecular factors involved, which this study aims to address through metabolomic and proteomic profiling.
  • The research involved analyzing 100 pork chops, aged for about two weeks, categorized by their tenderness using a star probe instrument, to identify differences in protein and metabolite levels.
  • Significant variations in the presence of 84 proteins and 22 metabolites were found between the most tender (Category A) and least tender pork chops (Category D), suggesting that tenderness is linked to slower pH decline and changes in muscle proteins.

Article Synopsis
  • - The PERSEUS study analyzed the effects of adding daratumumab (D) to the standard treatment VRd (bortezomib, lenalidomide, and dexamethasone) for adults with newly diagnosed multiple myeloma to see if it could improve outcomes.
  • - Participants were divided into two groups: one receiving D-VRd initially followed by D-R maintenance, and the other receiving standard VRd followed by lenalidomide alone.
  • - After about four years, results indicated that those who received D-VRd had better treatment responses and were more likely to remain alive and disease-free compared to the VRd-only group, with side effects being consistent with expectations for both treatments.

It was hypothesized that the longissimus thoracis (LT) muscle proteome, phosphoproteome, and metabolome could explain postmortem metabolism and tenderness differences in muscle from cattle supplemented zinc (Zn) and/or ractopamine hydrochloride (RH). High percentage Angus steers (N = 20) were fed in a 2 × 2 factorial assigned to Zn and RH treatments: control (CON; n = 10; analyzed 36 mg Zn/kg dry matter [DM]) or supranutritional Zn supplementation (SUPZN; n = 10; control diet + 60 mg Zn/kg DM [from ZnSO4] + 60 mg Zn/kg DM [from Zn-amino acid complex]) for the entire 89-d trial. During the 28 d before harvest, steers were blocked by body weight within Zn treatments to RH treatments of 0 (NO; n = 10) or 300 mg (RAC; n = 10) per steer per day.

The objective was to understand the impacts of secondary lipid oxidation products on calpain-2 activity and autolysis and, subsequently, to determine the quantity and localization of modification sites. 2-Hexenal and 4-hydroxynonenal incubation significantly decreased calpain-2 activity and slowed the progression of autolysis, while malondialdehyde had minimal impact on calpain-2 activity and autolysis. Specific modification sites were determined with LC-MS/MS, including distinct malondialdehyde modification sites on the calpain-2 catalytic and regulatory subunits.
