AI Article Synopsis
- Twenty-eight microsatellite markers were used to study the genetic variation of two local chicken breeds, Dagu Chicken and Beijing Fatty Chicken, across different farms using 125 samples.
- Genetic analysis revealed high polymorphism in the populations, with heterozygosity and polymorphic information content (PIC) values exceeding 0.5, indicating strong genetic diversity.
- Despite overall biodiversity retention, distinct genetic differences were noted between farms housing the same chicken breeds, suggesting variability in conservation effectiveness.
Article Abstract
Twenty-eight microsatellite markers were used to analyze the conservation efficiency of two local chicken breeds (Dagu Chicken and Beijing Fatty Chicken) in different farms. Genotypes were detected in 125 samples. The genetic variations among and within the populations were calculated by the number of alleles, gene frequency, genetic heterozygosity (H), PIC, F-statistics, Nei's genetic distance and UPGMA. High polymorphism was found in the four populations, and H and PIC values of each population were more than 0. 5. All loci detected in the study showed polymorphism and the number of alleles ranged from 2 to 22 in total population. Most of these loci were at Hardy-Weinberg equilibrium except two loci (LE110194, MCW0032). The four conservation farms for the two breeds were shown to have retained substantial biodiversity, indicating that the conservation programs are efficient. However, differences between the farms of the same breeds were observed.

Proton conducting electrochemical cells (PCECs) are efficient and clean intermediate-temperature energy conversion devices. The proton concentration across the PCECs is often nonuniform, and characterizing the distribution of proton concentration can help to locate the position of rate-limiting reactions. However, the determination of the local proton concentration under operating conditions remains challenging.

Hydrogel-based sensors have been widely studied for perceiving the environment. However, the simplest type of resistive sensors still lacks sensitivity to localized strain and other extractable data. Enhancing their sensitivity and expanding their functionality to perceive multiple stimuli simultaneously are highly beneficial yet require optimal material design and proper testing methods.

This study presents the synthesis and characterization of CsNaBiCl nanocrystals (NCs) doped with varying concentrations of In to improve their luminescent properties. Utilizing a colloidal solution method, we systematically varied the In concentration to identify the optimal alloying level for enhancing the photoluminescence (PL) properties of the CsNaBiCl NCs. Structural analysis confirmed that the In-alloyed NCs maintained high crystallinity and a uniform cubic shape.
