Audit of 100 consecutive basal cell carcinoma specimens at a secondary care centre in the UK.

Objective: To audit basal cell carcinoma resections against standard guidelines.

Methods: The retrospective study was done at the Department of Pathology, Sherwood Forest Hospital, Nottinghamshire, United Kingdom, from July 2020 to December 2020 and comprised basal cell carcinoma cases regardless of age and gender. All parameters laid down by the Royal College of Pathologists were matched with the data.

Chemoenzymatic surface decoration of Nisin-shelled nanoemulsions: Novel targeted drug-nanocarriers for cancer applications.

Nisin, a peptide used as a natural food preservative, is employed in this work for the development of a novel nanocarrier system. Stable and uniform nisin-shelled nanoemulsions (NSNE) with a diameter of 100 ± 20 nm were successfully prepared using 20 kHz flow-through ultrasonication technique. The NSNE showed limited toxicity, high bactericidal activity and high drug loading capacity (EE 65 % w/w).

The mechanism of sonochemical degradation of a cationic surfactant in aqueous solution.

The sonochemical degradation of the cationic surfactant, laurylpyridinium chloride (LPC), in water was studied at concentrations of 0.1-0.6 mM, all below its critical micelle concentration (15 mM).

Kinetics and mechanism for the sonochemical degradation of a nonionic surfactant.

The sonolytic degradation of the nonionic surfactant, octaethylene glycol monododecyl ether (C(12)E(8)), has been studied at various initial concentrations below and above its critical micelle concentration (CMC). It has been observed that the degradation rate increases with an increase in the initial concentration of the surfactant until the CMC is reached. Above the CMC an almost constant degradation rate is observed, suggesting that the surfactant in its monomer form is involved in the degradation process.

Sonochemical degradation of martius yellow dye in aqueous solution.

The sonolytic degradation of the textile dye martius yellow, also known as either naphthol yellow or acid orange 24, was studied at various initial concentrations in water. The degradation of the dye followed first-order kinetics under the conditions examined. Based on gas chromatographic results and sonoluminescence measurements of sonicated aqueous solutions of the dye, it is concluded that pyrolysis does not play a significant role in its degradation.
