The histone demethylase KdmB is part of a trimeric protein complex and mediates virulence and mycotoxin production in Penicillium expansum
Fungal Genet Biol. 2023 Sep 16:103837. doi: 10.1016/j.fgb.2023.103837. Online ahead of print.ABSTRACTEpigenetic modification of chromosome structure has increasingly been associated with alterations in secondary metabolism and sporulation defects in filamentous fungal pathogens. Recently, the epigenetic reader protein SntB was shown to govern virulence, spore production and mycotoxin synthesis in the fruit pathogen Penicillium expansum. Through immunoprecipitation-coupled mass spectrometry, we found that SntB is a member of a protein complex with KdmB, a histone demethylase and the essential protein RpdA, a histone deacety...

Policy, Systems, and Environmental Changes in Child Nutrition Programs: A Systematic Literature Review
Adv Nutr. 2023 Sep 14:S2161-8313(23)01377-7. doi: 10.1016/j.advnut.2023.09.004. Online ahead of print.ABSTRACTThe National School Lunch Program (NSLP) provides healthy food to millions of children annually. To promote increased lunch consumption, policy, systems, and environmental (PSE) change strategies are being implemented in child nutrition programs. An evaluation of the current evidence supporting PSE interventions in school nutrition programs is needed to facilitate evidence-based practices across the nation for programs. This systematic review aims to determine the quality and breadth of available evidence of the ef...

Cold atmospheric plasma fumigation suppresses postharvest apple Botrytis cinerea by triggering intracellular reactive oxygen species and mitochondrial calcium
In this study, the effects of cold atmospheric plasma (CAP) fumigation on apple B. cinerea under different exposure times and intensities were investigated. The growth of B. cinerea in vitro and in vivo was significantly suppressed by the CAP fumigation at least 700 μL/L for 5 min. To reveal the possible mechanism of antifungal activity of CAP fumigation, the pathogen was exposed to 700 μL/L and 1000 μL/L for 5 min, respectively. The results indicated that the CAP-treated spores of the pathogen underwent shrinkage, cell membrane collapse and cytoplasmic vacuolation. The results obtained from the fluorescent probe assay ...

Trade liberalization and nutrition transition: Evidence from China
Econ Hum Biol. 2023 Sep 9;51:101304. doi: 10.1016/j.ehb.2023.101304. Online ahead of print.ABSTRACTWe examine the impact of trade liberalization on the nutrition transition between 1997 and 2011. Our findings demonstrate that the reduction in tariff rates has had a significant effect on the dietary patterns of both rural and urban residents in the country. With the decrease in tariffs, there has been a noticeable increase in the consumption of animal products (such as meat and aquatic products), vegetables, beans and nuts, as well as packaged and processed foods. Simultaneously, there has been a decrease in the demand for ...

What turns an ant into a soldier or a forager? It may be all in their heads
Most worker carpenter ants have one of two fates: They either become foragers who look for food or soldiers who defend the nest. Levels of key hormones influence which role they crawl into. Now, a new study shows the ants’ blood-brain barrier plays a crucial role in this decision, regulating how much of one critical hormone seeps into developing ants’ brains by actively breaking it down. The findings, published last week in Cell , suggest the blood-brain barrier may play a previously unappreciated role in influencing social behavior in animals , including mammals, the authors argue. “[The study]...

Valorization of onion peel waste: From trash to treasure
Chemosphere. 2023 Sep 13:140178. doi: 10.1016/j.chemosphere.2023.140178. Online ahead of print.ABSTRACTGlobally, fruit and vegetables are consumed as raw, processed, or as an additive, accounting for approximately 50% of total food wastage. Among the fruits and vegetables, onion is well known for its potential bioactive components; however, peels of onion are a major concern for the environment and food industries. Effective utilization of onion peel methods should be needed to develop value-added products, which are more eco-friendly, cost-effective, and sustainable. Therefore, this review attempts to emphasize the conven...

Four new alkylamides from the fruits of < em > Piper retrofractum < /em > and antityrosinase evaluation
Nat Prod Res. 2023 Sep 15:1-10. doi: 10.1080/14786419.2023.2258542. Online ahead of print.ABSTRACTFour new alkylamides named retroframides A-D (1-4) together with twenty-two known compounds were isolated from the fruits of Piper rectrofractum. The structures of new compounds were elucidated on the basis of spectroscopic data including 2D NMR and chemical derivatization followed by GC-MS analysis. Of isolated compounds, piperine (25) and pellitorine (26) revealed moderate inhibition against tyrosinase with percentage inhibition of 36.1 and 40.7.PMID:37715311 | DOI:10.1080/14786419.2023.2258542
