Article Synopsis
- Recent advancements in quasi-2D perovskites, particularly ((PEA)(CsPbBr3)PbBr), have highlighted their exceptional optoelectronic properties and environmental resilience, creating diverse application possibilities.
- Structural differences in these materials, caused by varying values of "", lead to unique nonlinear behaviors that have not been fully explored yet.
- Comparative studies reveal that the = 5 quasi-2D perovskite showcases superior saturable absorption and optimal performance in laser applications, making it promising for ultrafast optics due to its favorable characteristics.
Widespread implementation of on-site water reuse is hindered by the limited availability of monitoring approaches that ensure microbial quality during operation. In this study, we developed a methodology for monitoring microbial water quality in on-site water reuse systems using inexpensive and commercially available online sensors. An extensive dataset containing sensor and microbial water quality data for six of the most critical types of disruptions in membrane bioreactors with chlorination was collected.

August 2002
Well spread pachytene bivalents with high-resolution multiple bands of zebrafish were obtained after the testes were treated with alkaline hypotonic solution and high chloroform fixative solution. This might be the pattern with the largest number of multiple bands obtained from fish chromosomes so far published. Both the number and character of the bands in each bivalent were stable.

- - The study successfully produced clear G-banding patterns in the chromosomes of Rana plancyti using natural aging, chloroform, and EDTA treatment for the first time, showcasing distinctive results.
- - A thorough analysis revealed that the characteristic and count of bands on homologous chromosomes from the same metaphase figures matched well, indicating consistency in the G-banding patterns.
- - The method described is straightforward, cost-effective, and yields stable results, potentially benefiting cytogenetic research in Rana plancyt and other amphibians.
Adipose tissue triacylglycerols are the quantitatively most important source of stored energy in animals. Hormone-sensitive lipase encoded by hormone-sensitive lipase gene (Hsl) is a multifunctional enzyme that catalyzes the hydrolysis of triacylglycerol stored in adipose tissue and cholesterol esters in the adrenals, ovaries, testes and macrophages. Using pig Hsl gene inserted into pBS labeled by the radioactive isotope and the digoxigenin as the probes respectively one band, 11.

A 512 bp long DNA fragment has been isolated by polymerase chain reaction from rice field eel genomic DNA using the primers for amplifying zinc finger repeats 7 to 13 of mammalian and reptilian ZFX-related genes.

- - Researchers used human sex chromosome probes to examine metaphase spreads of three fish species: Monopterus albus, Danio rerio, and Mastacembelus aculeatus, to study the conservation of sex chromosomal segments across different species.
- - The study found that the human X chromosomal probes revealed a varying number of conserved syntenic segments in the fish species' karyotypes—4 in Monopterus, 8 in Danio, and 6 in Mastacembelus—found across different homologous chromosomes.
- - No conserved segments were detected when probing with human Y chromosomal probes, leading to a discussion about the evolution of the X chromosome in vertebrates.
Article Synopsis
- A standard light microscope was modified to collect Z chromosomes from quail during mitotic-metaphase, followed by DNA extraction and amplification using DOP-PCR.
- The resulting DNA fragments, sized between 200-1,400 bp, were cloned into plasmids to create a specific DNA library for Z chromosomes.
- Subsequent chromosome painting showed strong signals on quail Z chromosomes, indicating the inserts were specific to these chromosomes, enabling further studies on syntenic groups and evolution of sex chromosomes in birds.
Article Synopsis
- The study explores how genome duplication and chromosome rearrangement contribute to vertebrate genome evolution, specifically focusing on Hox genes as evidence for this theory.
- Researchers mapped the chromosomal locations of Hox genes in the rice field eel, identifying 6 potential Hox clusters across several chromosomes (1, 2, 3, 6, 8, 10) with specific positional data.
- These findings align with previous chromosome microdissection studies and enhance understanding of the evolutionary origins of rice field eel chromosomes, supporting the concept of genome duplication.
