Article Synopsis
  • A genome-wide association study identified two significant QTLs on chromosome B09 linked to resistance against early and late leaf spots in peanuts, which are major diseases causing substantial economic losses.
  • A total of 46 QTLs were discovered, with eight classified as major QTLs, indicating that the B sub-genome has more resistance potential than the A sub-genome.
  • The study also pinpointed 74 non-redundant genes associated with resistance, including 12 candidate genes located in critical genomic areas for ELS and LLS, which could facilitate breeding efforts for disease-resistant peanuts.

Objective: This randomized, double-blind, placebo-controlled study evaluated the safety and efficacy of an intravenous (IV) nanocrystal formulation of meloxicam in subjects with moderate-to-severe pain following a standardized unilateral bunionectomy.

Methods: Fifty-nine subjects aged 18-72 years were randomized to receive doses of either 30 mg (n=20) or 60 mg (n=20) meloxicam IV or placebo (n=19), administered once daily as bolus IV injections over 15-30 seconds (two or three doses). Safety, the primary objective, was assessed by physical examination, clinical laboratory tests, and the incidence of adverse events (AEs).

Purpose: Interleukin (IL)-1β, an inflammatory molecule, contributes to the development of atherothrombosis and worsening of islet β-cell function. Canakinumab, a human monoclonal antibody, targets IL-1β-dependent inflammation and reduces the vascular inflammatory biomarker, high-sensitivity C-reactive protein (hsCRP), and other inflammatory cardiovascular biomarkers. Here, we aimed to assess the pharmacokinetic (PK) and pharmacodynamic characteristics, including the effect on hsCRP, of canakinumab in patients with type 2 diabetes mellitus (T2DM) after a 2-hour single-dose intravenous infusion.

Background: We aimed to assess the safety and tolerability of different doses of canakinumab versus placebo in patients with type 2 diabetes mellitus (T2DM).

Methods: Data were pooled from three studies in 1026 T2DM patients with different routes of administration, treatment regimens and follow-up duration. Canakinumab groups were categorised as low (0.

Background: To test formally the inflammatory hypothesis of atherothrombosis, an agent is needed that reduces inflammatory biomarkers such as C-reactive protein, interleukin-6, and fibrinogen but that does not have major effects on lipid pathways associated with disease progression.

Methods And Results: We conducted a double-blind, multinational phase IIb trial of 556 men and women with well-controlled diabetes mellitus and high cardiovascular risk who were randomly allocated to subcutaneous placebo or to subcutaneous canakinumab at doses of 5, 15, 50, or 150 mg monthly and followed over 4 months. Compared with placebo, canakinumab had modest but nonsignificant effects on the change in hemoglobin A1c, glucose, and insulin levels.

Background: Insulin therapy is often a delayed strategy in patients with type 2 diabetes mellitus because it is associated with weight gain, hypoglycaemia, and the need for subcutaneous injections. We aimed to assess the efficacy and safety of prandial Technosphere inhaled insulin compared with twice daily biaspart insulin.

Methods: In this randomised, open-label, parallel-group study, adult patients with type 2 diabetes mellitus and poor glycaemic control despite insulin therapy, with or without oral antidiabetes drugs, were enrolled from ten countries between Feb 23, 2006, and Aug 8, 2007.

Background: The purpose of this study was to compare treatment satisfaction among people with type 1 and type 2 diabetes after switching from insulin lispro to insulin aspart in continuous subcutaneous insulin infusion (CSII). Efficacy of glycemic control between treatments was also investigated.

Methods: Subjects using CSII with insulin lispro for 6 months or longer continued this therapy over a 4-week period and then switched to insulin aspart in CSII for 12 weeks.

Objective: The safety and efficacy of insulin aspart continuous subcutaneous insulin infusion (CSII) was compared with that of insulin lispro CSII in children and adolescents with type 1 diabetes.

Research Design And Methods: Children and adolescents aged 4-18 years with diagnosed type 1 diabetes >or=1 year previously and treated with insulin analog in a CSII >or=3 months were randomly assigned 2:1 to 16 weeks of insulin aspart CSII (n = 198) or insulin lispro CSII (n = 100) in this open-label, parallel-group, multicenter study. Standard diabetes safety and efficacy parameters were assessed.

Context: Weight-based dosing of GH is the standard of care for short children, although IGF-I is thought to be the main mediator of GH actions on growth.

Objective: The objective of the study was to test whether IGF-I levels achieved during GH therapy are determinants of the growth responses to GH treatment.

Design: This was a 2-yr, open-label, randomized, IGF-I concentration-controlled trial.
