Spores are the most resistant form of microbial cells, thus difficult to inactivate. The pathogenic or food spoilage effects of certain spore-forming microorganisms have been the primary basis of sterilization and pasteurization processes. Thermal sterilization is the most common method to inactivate spores present on medical equipment and foods. High pressure processing (HPP) is an emerging and commercial non-thermal food pasteurization technique. Although previous studies demonstrated the effectiveness of thermal and non-thermal spore inactivation, the in-depth mechanisms of spore inactivation are as yet unclear...

Cervical carcinoma is a frequent malignancy in developing countries despite being a preventable disease. For the first time, four screening tests were used simultaneously for identifying women with a risk of developing cervical cancer, to help clinicians and policy makers to implement the best strategy for reducing the burden of this disease. Women visiting a hospital in India were enrolled after institutional ethics clearance and informed consent. Visual inspection using acetic acid and Pap smear tests were performed on 2683 women, and 104 had abnormal cytology: atypical squamous cells of undetermined significance (n = 29), low-grade squamous intraepithelial lesion (n = 41), high-grade squamous intraepithelial lesion (n = 17), and squamous cell carcinoma (n = 17)...
