Reaction of BiCl3 with 2-(2-hydroxy-3-methoxyphenyl)benzimidazole (HL) in tetrahydrofuran (THF) under reflux gave mononuclear complex of formula [Bi(HL)2Cl3·H2O]. The binding interaction of the complex with bovine serum albumin (BSA) was investigated using the fluorescence quenching method. The experimental results showed that the complex could bind to BSA in the proportion of about 1:1. The binding reaction was spontaneous and hydrophobic force played major role in the reaction. The binding of the complex to BSA could change the microenvironment and conformation of BSA.

Benggang (collapsing hill) erosion is one of the most serious ecological problems in the south of China. Understanding the relationship between Benggang erosion and landscape pattern is conducive to the study of Benggang occurrence and development from the perspective of landscape ecology, with great significance for Benggang prevention and ecological protection. We classified the Lanxi River Basin in Anxi County, Fujian Province into 32 small watersheds.

Spin-dependent charge tunneling transport of magnetic nanocomposites under alternating current or direct current has revolutionized the understanding of the quantum-mechanical phenomenon in complex granular solids. The tunnel magnetodielectric (TMD) and tunnel magnetoresistance (TMR) effects are two critical functionalities in this context, where dielectric permittivity and electrical resistance, respectively, change in response to an applied magnetic field due to charge tunneling. However, the structural correlation between TMD and TMR, as well as the mechanisms, remains poorly understood, largely due to the challenges in directly characterizing nanoscale intergranular interactions.

Objectives: Tinea capitis remains a common fungal infection in children worldwide. Species identification is critical for determining the source of infection and reducing transmission. In conventional methods, macro- and microscopic analysis is time-consuming and results in slow fungal growth or low specificity.

We present an iron-photocatalyzed decarboxylative alkylation strategy involving carboxylic acids and Morita-Baylis-Hillman (MBH) acetates to synthesize -type tri- and tetrasubstituted alkenes with moderate to excellent stereoselectivity (/ ratio up to >19:1). This method is applicable to a broad range of structurally diverse primary, secondary, and tertiary alkyl carboxylic acids, as well as complex pharmaceutical and natural carboxylic acids, achieving efficient alkylation of various MBH acetates under mild conditions (>60 examples, with yields up to 96%). This approach offers a powerful strategy for streamlined alkylation.

Background: Traditional DNA microinjection methods used in mammals are difficult to apply to avian species due to their unique reproductive characteristics. Genetic manipulation in chickens, particularly involving immature follicles within living ovaries, has not been extensively explored. This study seeks to establish an efficient method for generating transgenic chickens through ovarian injection, potentially bypassing the challenges associated with primordial germ cell (PGC) manipulation and fertilized egg microinjection.
