To enhance anthralin efficacy against psoriasis and reduce its notorious side effects, it was loaded into various liposomal and ethosomal preparations. The nanocarriers were characterized for drug encapsulation efficiency, size, morphology and compatibility between various components. Optimum formulations were dispersed in various gel bases and drug release kinetics were studied. Clinical efficacy and safety of liposomal and ethosomal Pluronic®F-127 gels were evaluated in patients having psoriasis (clinicaltrials.gov identifier is NCT03348462). Safety was assessed by recording various adverse events. Drug encapsulation efficiency ≥97.2% and ≥77% were obtained for liposomes and ethosomes, respectively. Particle sizes of 116 to 199 nm and 146 to 381 nm were observed for liposomes and ethosomes, respectively. Fourier-Transform infrared (FT-IR) spectroscopy and differential scanning calorimetry (DSC) studies confirmed the absence of interaction between anthralin and various nanocarrier components. Tested gel bases showed excellent ability to sustain drug release. At baseline, the patients had a median Psoriasis Area and Severity Index (PASI) of 3.4 for liposomes and 3.6 for ethosomes without significant difference. After treatment, mean PASI change was −68.66% and −81.84% for liposomes and ethosomes, respectively with a significant difference in favor of ethosomes. No adverse effects were detected in both groups. Anthralin ethosomes could be considered as a potential treatment of psoriasis.

A combination of salt (NaCl) high concentration and curing salt was investigated for their role in warmed-over flavor (WOF) and color changes during charqui meats processing. WOF was measured by TBARS method in uncured charqui meat (CH) and in cured charqui known in Brazil as Jerked beef (JB). WOF occurred substantially in CH and sodium nitrite was able to inhibit 40-45% (p<0.05)

Pyridwotine (PYR), a mature collagen crosslink, ‐was measured in Ross hen breast meat, Pectoralis major, age ranging from 20 to 540 days and its concentration varied between 0.009 to 0.101 mol/mol collagen, respectively. PYR concentration was inversely related to collagen solubility in muscle homogenates (P>0.05) and total collagen content increased from 0.448 to 0.568% from 20 to 540 days, respectively. Shear values analyzed by texturometer showed a direct relationship between PYR amount with advancing poultry aging irrespective of collagen quantity (P > 0.05). Finally, there was also a direct relationship between the increase of PYR concentration and collagen solubility measured in Ringer solution.
