Volatile Byproducts of Carotenoid Degradation as Biomarkers of Maize Infestation by the Maize Weevil () (Motsch.).

Maize () is a major global food crop and a source of industrial raw materials. Effective postharvest storage is important for national food security programs, international trade, and global agriculture economics. The maize weevil () is a primary postharvest insect pest that infests maize during storage and leads to significant losses.

The costs of competition in distributing scarce research funds.

Research funding systems fundamentally influence how science operates. This paper aims to analyze the allocation of competitive research funding from different perspectives: How reliable are decision processes for funding? What are the economic costs of competitive funding? How does competition for funds affect doing risky research? How do competitive funding environments affect scientists themselves, and which ethical issues must be considered? We attempt to identify gaps in our knowledge of research funding systems; we propose recommendations for policymakers and funding agencies, including empirical experiments of decision processes and the collection of data on these processes. With our recommendations, we hope to contribute to developing improved ways of organizing research funding.

Ibrutinib in Early-Stage Chronic Lymphocytic Leukemia: The Randomized, Placebo-Controlled, Double-Blind, Phase III CLL12 Trial.

Purpose: The CLL12 trial reassesses the watch-and-wait consensus for early-stage chronic lymphocytic leukemia (CLL) in the context of targeted therapies.

Methods: The German CLL Study Group conducted a randomized, double-blind, placebo-controlled phase III trial with 363 patients with asymptomatic, treatment-naïve Binet stage A CLL at increased risk of progression to receive ibrutinib (n = 182) at a daily dose of 420 mg or placebo (n = 181). Additionally, 152 low-risk patients were allocated to the watch-and-wait group.

The origin and metabolic fate of 4-hydroxybenzoate in Arabidopsis.

The contribution of p-coumarate β-oxidation and kaempferol cleavage to the pools of glycosylated, free and cell wall-bound 4-hydroxybenzoate is organ-dependent in Arabidopsis. 4-Hydroxybenzoate (4-HB) is a vital precursor for a number of plant primary and specialized metabolites, as well as for the assembly of the plant cell wall. In Arabidopsis, it is known that 4-HB is derived independently from phenylalanine and tyrosine, and that the metabolism of phenylalanine into 4-HB proceeds via at least two biosynthetic routes: the β-oxidation of p-coumarate and the peroxidative cleavage of kaempferol.

The vices and virtues of medical models of obesity.

Despite numerous public health organizations supporting the pathologization of obesity and considering recent obesity rates a health crisis, many researchers in the humanities, social sciences, and even in the health sciences remain unconvinced. In this paper, we address a set of arguments coming from these academic fields that criticize medical models of obesity for their supposedly flawed diagnostic categories that shift focus onto individuals and support moralizing judgements. Clarifying some key claims in these models and explicating the view of obesity in terms of energy dysregulation, we aim to tease apart misunderstandings and argue that not only do these models not say what they are often accused of saying, but their apparent vices may actually be virtues in helping to combat stigma.
