The 'photosynthetic C pathway' links carbon assimilation and growth in California poplar.

Although primarily studied in relation to photorespiration, serine metabolism in chloroplasts may play a key role in plant CO fertilization responses by linking CO assimilation with growth. Here, we show that the phosphorylated serine pathway is part of a 'photosynthetic C pathway' and demonstrate its high activity in foliage of a C tree where it rapidly integrates photosynthesis and C metabolism contributing to new biomass via methyl transfer reactions, imparting a large natural C-depleted signature. Using CO-labelling, we show that leaf serine, the S-methyl group of leaf methionine, pectin methyl esters, and the associated methanol released during cell wall expansion during growth, are directly produced from photosynthetically-linked C metabolism, within minutes of light exposure.

Prevalence and key determinants of the triple burden of childhood malnutrition in Southeast Asian countries: a systematic review and meta-analysis within an adapted socio-ecological framework.

The triple burden of malnutrition (TBM) is increasing globally, but significant evidence gaps exist regarding its burden and drivers among children in Southeast Asian (SEA) countries. We systematically searched four databases (PROSPERO-CRD42023420129) and Google Scholar through February 2024. We assessed stunting and overweight prevalence among children aged 0-18 years old across four SEA countries (Indonesia, Malaysia, Thailand, and Vietnam) from recent national surveys.

The Role of Complementary Feeding Practices in Addressing the Double Burden of Malnutrition among Children Aged 6-23 Months: Insight from the Vietnamese General Nutrition Survey 2020.

: Optimal infant and young child feeding (IYCF) practices are crucial to addressing the double burden of malnutrition (DBM), encompassing undernutrition (including micronutrient deficiencies) and overnutrition. This study examined the demographic and socioeconomic determinants of IYCF practices, and their impacts on the DBM among 2039 Vietnamese children aged 6-23 months from the General Nutrition Survey 2020. Thirteen IYCF indicators recommended by the WHO/UNICEF were evaluated.

Quantitative Characterization of Fluorine-Centered Noncovalent Interactions in Crystalline Benzanilides.

Six isomeric molecules, featuring a minimum of three fluorine atoms on either the benzoyl or aniline side, have been synthesized, crystallized and characterized through single crystal X-ray diffraction (SCXRD). In addition, two other compounds, containing six fluorine atoms, three on each of the benzoyl and aniline side of the benzanilide scaffold have also been characterized through SCXRD. This current study aims to augment the capacity for hydrogen bond formation, specifically involving organic fluorine, by elevating the acidity of the involved hydrogens through the incorporation of highly electronegative fluorine atoms, in the presence of strong N-H⋅⋅⋅O=C H-bonds.
