Crystals in urinary sediment are commonly recognized structures, typically identified by a combination of crystal morphology and urine pH. In this paper, we present the first reported case of EDDP (2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidene) crystals, the primary metabolite of methadone, in a 67-year-old male with hepatorenal syndrome. Routine urinalysis revealed numerous needle-shaped crystals, which prompted further investigation.

Background: The present research work was done to evaluate the anatomical differences among selected species of the family Bignoniaceae, as limited anatomical data is available for this family in Pakistan. Bignoniaceae is a remarkable family for its various medicinal properties and anatomical characterization is an important feature for the identification and classification of plants.
Methodology: In this study, several anatomical structures were examined, including stomata type and shape, leaf epidermis shape, epidermal cell size, and the presence or absence of trichomes and crystals (e.

Bacterial biofilms formed by and pose significant challenges in treating cystic fibrosis (CF) airway infections due to their resistance to antibiotics. New therapeutic approaches are urgently needed to treat these chronic infections. This study aimed to investigate the antibiofilm potential of various plant extracts, specifically targeting mucoid and small colony variants of and and strains.

This approach significantly optimizes thermal compensation and facilitates rapid assessment of the light-emitting behavior trends of Tm: YAG lasers. Firstly, the thermal behavior of conventional and multi-segment bonded Tm: YAG crystals is analyzed.

Acetyl xylan esterase plays a crucial role in the degradation of xylan, the major plant hemicellulose, by liberating acetic acid from the backbone polysaccharides. Acetyl xylan esterase B from Aspergillus oryzae, designated AoAxeB, was biochemically and structurally investigated. The AoAxeB-encoding gene with a native signal peptide was successfully expressed in Pichia pastoris as an active extracellular protein.
