Does season regulate heterochronous leaf growth? Mechanisms of petiole-lamina trade-offs in broad-leaved woody plants of the Tianshan Mountains.

As the core of leaf functional traits, the trade-off relationship between the petiole and lamina expresses the plant's adaptability to the environment in terms of support structure and photosynthesis. We investigated the proportions of allometric growth in the relationship between the petiole and the lamina of broadleaf woody plants in temperate highland Tianshan Mountains montane forests through three dimensions (length, area, and mass), including the length of the lamina (LL) and the length of the petiole (PL), and the area of the lamina (LA) and petiole cross sectional area (PCA) versus the mass of the lamina (LM) and the mass of the petiole (PM), as well as exploring the characteristics of the variance in response to seasonal changes. We found that the functional traits in all three dimensions showed a clear convergent evolution as the seasons progressed, that is, a "seasonal effect" of increasing and then decreasing.

From a bee's eye: Effects of UV bullseye size on reproductive success in a dioecious vine (Cucurbitaceae).

Descriptions of floral traits based on the visual capabilities of pollinators would advance our understanding of flower evolution and plant-pollinator relationships. One such trait is the contrasting UV bullseye color pattern, which is invisible to human eyes but can be perceived by bee pollinators. However, it remains largely unknown how UV bullseye size affects male and female reproductive fitness.

The crosstalk between senescence, tumor, and immunity: molecular mechanism and therapeutic opportunities.

Cellular senescence is characterized by a stable cell cycle arrest and a hypersecretory, proinflammatory phenotype in response to various stress stimuli. Traditionally, this state has been viewed as a tumor-suppressing mechanism that prevents the proliferation of damaged cells while activating the immune response for their clearance. However, senescence is increasingly recognized as a contributing factor to tumor progression.

Connection between oral health and chronic diseases.

Chronic diseases have emerged as a paramount global health burden, accounting for 74% of global mortality and causing substantial economic losses. The oral cavity serves as a critical indicator of overall health and is inextricably linked to chronic disorders. Neglecting oral health can exacerbate localized pathologies and accelerate the progression of chronic conditions, whereas effective management has the potential to reduce their incidence and mortality.
