Construction costs and tradeoffs in carnivorous pitcher plant leaves: towards a pitcher leaf economic spectrum.

Background: Leaf economic theory holds that physiological constraints to photosynthesis have a role in the coordinated evolution of multiple leaf traits, an idea that can be extended to carnivorous plants occupying a particular trait space that is constrained by key costs and benefits. Pitcher traps are modified leaves that may face steep photosynthetic costs: a high-volume, three-dimensional tubular structure may be less efficient than a flat lamina. While past research has investigated the photosynthetic costs of pitchers, the exact suite of constraints shaping pitcher trait variation remain under-explored-including constraints to carnivorous function.

Characterization of the complete mitochondrial genome of Wang, Othman, Qiu and Borzée, 2023 (Amphibia, Caudata, Hynobiidae) and its phylogenetic implications.

(Caudata, Hynobiidae) is a recently described species, identified in 2022, and is thus not widely known. In this study, we sequenced and annotated the complete mitogenome of . The resulting mitochondrial genome is 16,406 bp in length and comprises 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNA), 22 transfer RNA genes, and a non-coding region.

A comprehensive analysis of the prognostic value, expression characteristics and immune correlation of MKI67 in cancers.

Background: nuclear-associated antigen Ki67 (Ki67) emerges as a clinically practical biomarker for proliferation assessment among many cancer types. However, the definite prognostic value of Ki67 against a specific cancer type has remained vague. This study aims to perform a comprehensive pan-cancer analysis of the prognosis value of Ki67 across various cancer types.

Effects of different concentrations of chlormequat chloride on bacterial community composition and diversity in peanut soil.

The application of pesticides may have significant impacts on soil environment and communities. In order to understand the deep relationship between the application of chlormequat chloride (CC) and the bacterial community in peanut soil, high-resolution characterization was performed using peanut soil samples (12 points; 0-20 cm rhizosphere soil) from untreated and sprayed with different concentrations of CC. Experimental data showed that with the increase of concentration, operational taxonomic units (OTUs) richness showed a decreasing tendency.

Efficient and stable near-infrared InAs quantum dot light-emitting diodes.

Visible quantum dot light-emitting diodes have satisfied commercial display requirements. However, near-infrared counterparts considerably lag behind due to the inferior quality of near-infrared quantum dots and limitations in device architecture suitable for near-infrared electroluminescence. Here, we present an efficient strategy using zinc fluoride to balance ZnSe shell growth across different core quantum dot facets, producing highly regular InAs/InP/ZnSe/ZnS quantum dots with near-unity quantum yield.
