π-Spacer Engineering: Driving Near-infrared Aggregation Induced-emission and Mechanofluorochromism in Carbazole-biscyanostilbenes.

In this study, we report the design and synthesis of two novel carbazole-based bis-cyanostilbenes incorporating phenyl and thiophene π-spacer units to investigate their distinct impacts on photophysical properties. Notably, the thiophene-based derivative exhibits remarkable far-red/near-infrared (NIR) solid-state emission, with an emission peak at 732 nm, which shifts to 750 nm upon mechanical grinding, demonstrating pronounced mechanochromic fluorescence in the NIR region. Although its quantum yield is moderate, the ability to modulate its emission through mechanical stimuli opens exciting opportunities for stimuli-responsive NIR applications.

Evaluation of Antibacterial Activities of Aqueous Extract of Black Pepper (Piper nigrum L) Seeds against the Gram Positive Staphylococcus aureus and Gram-Negative Escherichia coli.

Antibiotic resistance (AMR) represents a serious threat to public health and poses challenges in disease prevention and treatment despite various efforts to combat it. Evaluation of the in vitro antibacterial activity of aqueous extracts of black pepper seeds (Piper nigrum L.) against two infectious pathogens: Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli.

Glowing discoveries: Schiff base-cyanostilbene probes illuminating metal ions and biological entities.

Schiff bases featuring cyanostilbene units have emerged as versatile and highly effective probes for the selective detection of various metal ions as well as biologically important species. This review comprehensively highlights recent advances in the development and application of the probes, which exhibit remarkable Aggregation-Induced Emission (AIE), Twisted Intramolecular Charge Transfer (TICT), and Excited-State Intramolecular Proton Transfer (ESIPT) properties. These unique structural characteristics facilitate their potential applications in the detection of biologically important metal ions such as Zn, Fe, Cu, Hg and Co ions with high sensitivity and selectivity.

Representation of Racially Minoritized Patients on Dermatology Private Practice Websites.

Images on the homepages of private practice dermatology websites often do not reflect the racial diversity of the metropolitan area in which each practice is located. A Google Maps scraper (Apify) was used to identify websites for private practices in 27 United States metropolitan areas selected from the 2020 U.S.

Profitability and meat quality of fast-, medium- and slow-growing meat-type chicken genotypes as affected by growth and length of rearing.

The study aimed to evaluate the profitability, meat quality, and carcass parameters of fast-, medium-, and slow-growing meat-type chicken genotypes of Bangladesh. Nine hundred DOCs were randomly allocated to 6 treatments: T = commercial broilers, T = CPF-3 (central poultry farm-3), T = cockerel, T = , T = NDD (non-descriptive ), and T = , having 5 replications of 30 chicks each. Birds were reared under complete confinement until their respective market ages (commercial broilers = 35 d; CPF-3 = 45 d; cockerel = 56 d, and  = 77 d;  = 63 d and NDD = 77 d) and fed commercial broiler diets.
