Investigating antimicrobial and antioxidant activity of liquid smoke and physical-chemical stability of bacon subjected to liquid smoke and conventional smoking.

Liquid smoke, an alternative to traditional wood burning smoking, enhances product value by imparting desirable characteristics such as aroma, flavor, and color. Furthermore, it contains components with inherent antimicrobial and antioxidant properties. This study compares the effects of liquid smoke and conventional smoking methods in bacon processing.

Rosacea-specific quality of life questionnaire: translation, cultural adaptation and validation for Brazilian Portuguese.

Background: Brazil does not have a rosacea-specific quality of life questionnaire.

Objectives: translation into Brazilian Portuguese, development of cultural adaptation, and validation of the RosaQoL disease-specific questionnaire for rosacea of any subtype.

Methods: the recommended procedures for translation, cultural adaptation, and validation of an instrument were followed, and three interviews were conducted: baseline; seven to fourteen days after baseline; and at four to six months.

In vivo confocal Raman spectroscopy for intrinsic aging and photoaging assessment.

Background: In vivo confocal Raman spectroscopy is a non-invasive method to assess either the epidermis or the dermis composition. Few studies have focused on dermis collagen alterations through intrinsic aging and photoaging.

Objective: This study evaluated the in vivo Raman spectra from the dermis of a photoexposed site versus a non-photoexposed region in different age groups, and evaluated the correlation between peak intensities and age, photoaging score and the amount of collagen assessed with histology and high frequency ultrasound (HFUS).
