AI Article Synopsis

  • - Biofortification aims to enhance micronutrient levels in staple crops to help combat global deficiencies, with this paper reviewing its effectiveness in real-world settings through four different Impact Pathways.
  • - The systematic review included 25 studies, revealing that particularly in farmer households (Impact Pathway 4), there is evidence of improved micronutrient status, notably vitamin A from orange sweet potato.
  • - The findings suggest that biofortified crops can effectively contribute to reducing micronutrient deficiencies, emphasizing the need for continued research to explore their impact through the other three pathways for broader implementation.

Article Abstract

Biofortification is the process of increasing the concentrations and/or bioavailability of micronutrients in staple crops and has the potential to mitigate micronutrient deficiencies globally. Efficacy trials have demonstrated benefits of consuming biofortified crops (BFCs); and in this paper, we report on the results of a systematic review of biofortified crops effectiveness in real-world settings. We synthesized the evidence on biofortified crops consumption through four Impact Pathways: (1) purchased directly; (2) in informal settings; (3) in formal settings; or (4) in farmer households, from their own production. Twenty-five studies, covering Impact Pathway 1 (five studies), Impact Pathway 2 (three), Impact Pathway 3 (three), Impact Pathway 4 (21) were included. The review found evidence of an improvement in micronutrient status via Impact Pathway 4 (mainly in terms of vitamin A from orange sweet potato) in controlled interventions that involved the creation of demand, the extension of agriculture and promotion of marketing. In summary, evidence supports that biofortified crops can be part of food systems interventions to reduce micronutrient deficiencies in farmer households; ongoing and future research will help fully inform their potential along the other three Impact Pathways for scaling up.

Increasing frequencies of heatwaves threaten marine ectotherm species but not all alike. In exposed habitats, some species rely on a higher capacity for passive tolerance at higher temperatures, thereby extending time-dependent survival limits. Here we assess how the involvement of the cardiovascular system in extended tolerance at the margins of the thermal performance curve is dependent on warming rate.

A global decline in male fertility has been reported, and climate change is considered a major cause of this. Climate change refers to long-term shifts in temperatures and weather patterns, and results from greenhouse gas emissions like carbon dioxide and methane that act as a blanket wrapped around the earth, trapping heat and elevating temperatures. Sad to say, the consequences of climatic variation are beyond the dramatic elevated temperature, they include cold stress, increased malnutrition, air pollution, cardiovascular diseases respiratory tract infections, cancer, sexually transmitted infections, mental stress, and heat waves.

Most blood cells derive from hematopoietic stem cells (HSCs), originating from endothelial cells. The induction of HSCs from endothelial cells occurs during mid-gestation, and research has revealed multiple steps in this induction process. Hemogenic endothelial cells emerge within the endothelium, transition to hematopoietic cells (pre-HSCs), and subsequently mature into functional HSCs.

Non-small cell lung cancer (NSCLC) is the most common and prevalent subtype of lung cancer and continues to be one of the leading causes of cancer-related deaths worldwide. Despite various treatment options, a majority of NSCLC patients continue to experience disease progression and associated side effects, which are largely attributed to drug resistance, indicating the need for alternative strategies to combat this deadly disease. Among various applicable alternative approaches, repurposed drugs such as arsenic compounds have been shown to exert anticarcinogenic properties against NSCLC and possess the ability to overcome drug resistance mechanisms.
