BACKGROUND: Commonly the magnitude and frequency of bradycardia is underestimated in the neonatal unit due to the long averaging time used in bedside oximeters. We aimed to assess the frequency and severity of bradycardia in preterm infants using the lowest averaging time (2 s) available on a clinical oximeter, compared with bradycardia detected using electrocardiogram (ECG), and whether bradycardia severity and postmenstrual age affected cerebral oxygenation. METHODS: Preterm infants (10 M/9F) were studied longitudinally at 26-31 (very preterm) and 32-38 weeks (late preterm) postmenstrual age...

Saponification is the process in which triglycerides are combined with a strong base to form fatty acid metal salts during the soap-making process. The distribution of unsaturated and saturated fatty acid determines the hardness, aroma, cleansing, lather, and moisturizing abilities of soaps. Plant extracts, such as rosemary, vegetable, and essential oils are frequently added to soaps to enhance quality and sensory appeal. Three natural soaps were formulated using cold saponification to produce a base or control bar (BB), hibiscus rosehip bar (H), and a forest grove bar (FG)...

Neoadjuvant treatment options for human epidermal growth factor receptor-2 (HER-2)-enriched and luminal B molecular subtypes of clinical breast cancer include HER-2-targeted therapy with chemotherapy or anti-hormonal therapy. These treatment options result in systemic toxicity and acquired tumor resistance. Minimally toxic naturally occurring phytochemicals may represent testable alternatives to conventional therapy. HER-2-overexpressing tumorigenic human mammary epithelial 184-B5/HER cells represent a model for the HER-2-enriched breast cancer subtype...

Pressure treatment of ready-to-eat (RTE) meats extends the shelf life and reduces risks associated with Listeria monocytogenes . However, pressure reduces numbers of Listeria on ham by less than 5 log (CFU/g) and pressure effects on other meat microbiota are poorly documented. This study investigated the impact of pressure and RTE meat microbiota, with or without nisin and rosemary oil, on survival of Listeria after refrigerated storage. Ham was inoculated with a 5-strain cocktail of L. monocytogenes alone or with a cocktail of RTE meat microbiota consisting of Brochothrix thermosphacta , Carnobacterium maltaromaticum , Leuconostoc gelidum , and Lactobacillus sakei ...
