TL;DR: Multi-approach strategies, involving the development of improved recipes and processing, nutrition education, access to safe water, good sanitation, economic empowerment of women, reduction in workload, and promotion of breastfeeding, are recommended solutions to the problems of weaning foods in West Africa.
Abstract: This paper reviews the weaning practices and weaning food problems in West Africa. Traditional weaning foods in the region have low-density value and are characterized by low protein low energy density and high bulk. In addition factors such as early introduction of solid foods and poor hygienic practices place infants at high risk of malnutrition growth retardation infection and high mortality resulting from diseases such as diarrhea whooping cough and acute respiratory infection. Addressing the problems of weaning foods in West Africa requires multi-approach strategies including formulation and development of weaning foods of high nutritive value nutrition education access to safe water and sanitation development of recipe books for weaning foods of high nutrient density improvement of purchasing power of women appropriate time allocation for women and breast-feeding promotion.

TL;DR: An optimized mammalian transient expression system, capable of producing up to 400mg/L of native secreted antibodies in less than a week, is described, composed of commercially available components and based on expression in the fast growing suspension cell line, FreeStyle™ 293-F (HEK-293F).

TL;DR: The authors investigated the effect of NaCl at 0, 1 and 2% (w/w, flour base) on the gluten network formation during dough development, the dough rheology, and the baking characteristics of two commercial flours containing different levels of protein (9.0 and 13.5%).

TL;DR: Young adult rats were fed diets that included low protein or 60% and 40% of carbohydrate calories for 1 mo, and the reduced total IGF-I under these dietary conditions could not be explained by an increase in IGFBP-3 protease activity, or a decrease in the association of IGF-i with IGF BP-3 and the acid labile subunit.
Abstract: The hierarchy of diet components (e.g., protein, carbohydrate, vitamins, and minerals) influencing growth hormone (GH), insulin-like growth factor-I (IGF-I), and their binding proteins (BP) is not well defined. Young adult rats were fed diets for 1 mo that included low protein or 60% and 40% of carbohydrate calories. We hypothesized that levels of both hormones, their dominant BPs and liver IGF-I mRNA would fall, and that part of the mechanism for decreasing serum IGF-I would be enhanced IGFBP-3 protease activity. By day 30, caloric deprivation to 40% lowered serum GH, GHBP, IGF-I and IGFBP-3, and liver IGF-I mRNA. This was the only condition resulting in body weight loss (-15%) vs 39% gain in controls. Restriction to 60% calories had no impact on BP levels, slightly lowered IGF-I (-12%) in the face of a 95% inhibition of GH levels, while allowing a modest 9% body weight gain. Protein deprivation lowered serum GH, IGF-I and IGFBP-3, and liver IGF-I mRNA, while GHBP levels were normal. The reduced total IGF-I under these dietary conditions could not be explained by an increase in IGFBP-3 protease activity, or a decrease in the association of IGF-I with IGFBP-3 and the acid labile subunit.

TL;DR: It is argued here that plant protein quality is subject to considerable variation from genetic and environmental influences and thus may significantly impact herbivore performance and the behavioral and physiological adaptations of insects to variation in protein quality.
Abstract: Protein quality has received comparatively little attention as a factor in host plant suitability for insects. It is argued here that plant protein quality is subject to considerable variation from genetic and environmental influences and thus may significantly impact herbivore performance. Furthermore, other phytochemicals that are ingested with protein may negatively impact protein utilization. There is a wide distribution of alkylating agents found in plants (e.g., quinones, phenolics, aldehydes, pyrrolizidine alkaloids, sesquiterpene lactones, isothiocyanates) that form covalent bonds with nucleophilic side chains of proteins (e.g., -SH, -NH, -NH2) and potentially limit amino acid availability. The behavioral and physiological adaptations of insects to variation in protein quality are also discussed. Finally, preliminary evidence for physiological adaptation to low protein quality in Helicoverpa zea is provided. The potential role of protein quality in host plant specialization is summarized. © 1996 Wiley-Liss, Inc.
