Structure, Mechanical Properties, and Rheological Characteristics of Poly(Butylene Adipate-co-Terephthalate)-Polylactic Acid Blends Modified via In Situ Maleic Anhydride Grafting.

Polylactic acid (PLA) materials face inherent limitations in many applications due to their low toughness. To address this challenge, this study employed a reactive melt-grafting method to prepare maleic anhydride (MA)-grafted poly(butylene adipate-co-terephthalate) (PBAT-MA), providing an effective approach to improve the interfacial compatibility between PLA and PBAT, thereby significantly enhancing the toughness and impact resistance of PLA and expanding its application scope. The grafting reaction process of PBAT-MA was investigated, as well as its toughening mechanism and effect on PLA.

Recurrent mutations drive the rapid evolution of pesticide resistance in the two-spotted spider mite .

The genetic basis of pesticide resistance has been widely studied, but the exact nature of this evolutionary process in the field is often unclear, particularly when a limited number of populations is considered and when there is a lag between the evolutionary event and its investigation. We showed that an unprecedented number of recurrently evolved mutations in an arthropod pest, the two-spotted spider mite , drive the rapid evolution of resistance to a recently commercialized acaricide, cyetpyrafen. We first observed high levels of resistance that appeared and became widespread within three years.

Genomes of Two Monophagous Weevils and Their Host Plant Provide Insights Into Evolution of Plant Defence and Insect Counter-Defence.

Plant secondary metabolites play important roles in defence against herbivorous insects. However, many insects can overcome plant defences even when they produce a rich toxin load, and an arms race between plants evolving new toxins and insects evolving to counter them is expected. Here, we deciphered genomic features linked to a potential race between the tree of heaven and two monophagous weevils that only feed on this tree species, with the tree of heaven producing a rich set of secondary metabolites involving about 745 compounds.

Endothelin receptor antagonists (ERAs) can potentially be used as therapeutic drugs to reduce hypertension caused by small molecule tyrosine kinase inhibitors (TKIs).

The emergence of targeted anti-tumor drugs has significantly prolonged the lifespan and improved the prognosis of cancer patients. Among these drugs, vascular endothelial growth factor (VEGF) inhibitors, particularly novel small molecule tyrosine kinase inhibitors (TKIs), are extensively employed as VEGF inhibitors; however, they are also associated with a higher incidence of complications, with hypertension being the most prevalent cardiovascular toxic side effect. Currently, it is widely accepted that TKIs-induced hypertension involves multiple mechanisms including dysregulation of the endothelin (ET) axis, reduced bioavailability of nitric oxide (NO), imbalance in NO-ROS equilibrium system, vascular rarefaction, and activation of epithelial sodium calcium channels; nevertheless, excessive activation of ET system appears to be predominantly responsible for this condition.

Hierarchical architecture of neo-sex chromosomes and accelerated adaptive evolution in tortricid moths.

Sex chromosomes can expand through fusion with autosomes, thereby acquiring unique evolutionary patterns. In butterflies and moths (Lepidoptera), these sex chromosome-autosome (SA) fusions occur relatively frequently, suggesting possible evolutionary advantages. Here, we investigated how SA fusion affects chromosome features and molecular evolution in leafroller moths (Lepidoptera: Tortricidae).

PpNAP4 and ethylene act in a regulatory loop to modulate peach fruit ripening and softening.

Ripening significantly influences fruit quality and commercial value. Peaches (Prunus persica), a climacteric fruit, exhibit increased ethylene biosynthesis and decreased fruit firmness during ripening. NAC-like proteins activated by AP3/P1 (NAP) proteins are a subfamily of NAC transcription factors, and certain NAPs have been shown to intervene in fruit ripening.

Preparation of high-performance antibacterial/antifungal citric acid-starch adhesives based on physical entanglement and chemical crosslinking.

Starch-based wood adhesives are widely used as environmentally friendly and formaldehyde-free alternatives in the manufacturing of wood products. However, their poor water resistance and inability to inhibit bacterial/fungal growth limit their practicality. To address this issue, a physicochemical double-crosslinked network structure between citric acid, starch, and wood was prepared in this study by physically entangling the wood structure and chemically crosslinking the starch molecules, with citric acid preventing the activity of various enzymes and denatured proteins within microbial cells, thereby inhibiting bacterial and fungal growth.

SlECA4, an epsin-like clathrin adaptor protein, improves tomato heat tolerance via clathrin-mediated endocytosis.

Clathrin-mediated endocytosis (CME) is one of the main pathways for plant cells to internalize membrane proteins in response to changing environmental conditions. The Epsin-like Clathrin Adaptor (ECA) proteins play important roles in the assembly of the clathrin coat; however, their involvement in plant responses to heat stress remains unclear. Here we report that in tomato (Solanum lycopersicum), Epsin-like Clathrin Adaptor 4 (SlECA4) expression responded to heat stress.
