Ultrasound (US) imaging is a well-established diagnostic technique to image soft tissues in real time, while photoacoustic (PA) is an emerging imaging technique employed to collect molecular information. Integration of PA and US imaging provides complementary information enhancing diagnostic accuracy without employing ionizing radiations. The development of contrast agents able to combine PA and US features is pivotal to improve the significance of PAUS imaging and for PAUS-guided treatment of neoplasms. Here, we demonstrate in relevant ex-vivo models that disassembling passion fruit-like nano-architectures (pfNAs) can be employed in PAUS imaging...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease mainly caused by high fat diets and sudden feed changes, vitamin and energy deficiency, and inflammatory processes. Fatty liver leads to cirrhosis, hepatocellular carcinoma as well as liver failure. Lifestyle-modifying such as weight loss and healthy diet have an inverse correlation with the risk of fatty liver. The promising effect of a diet rich in vegetables and fruits against fatty liver has been evidenced by several empirical studies focused on flavonoids...

Frank R Greer
There is a long history of the use of starch in infant feeding. Proprietary infant foods (1867-1920) contained added starch from either cereal grains or malted carbohydrates. When evaporated milk became available in the 1920s, the use of proprietary foods fell out of favor. Evaporated milk formulas were a mixture of milk, water, and modified starch or milk sugar (lactose). By the late 1920s, however, corn syrup became the most common modified starch added to evaporated milk formulas as it was widely available, inexpensive, and readily accepted...

No data exist on the prevalence of ideal cardiovascular health metrics in a national sample of U.S. veterans. We assessed the prevalence of ideal Life's Simple Seven (LSS) metrics in a cross-sectional study of 554,855 U.S. veterans enrolled in the Million Veteran Program (MVP) from 2011 to 2017. We used the American Heart Association's established criteria to categorize each LSS metric as either poor, intermediate, or ideal for a veteran at time of MVP enrollment. Information on adiposity/body mass index, smoking status, diet, and physical activity was obtained from self-reported survey data, and clinical measurements for total cholesterol, blood pressure, and plasma glucose were obtained from electronic health records...

Foods are natural sources of substances that may exert crucial effects on the nervous system in humans. Some of these substances are the neurotransmitters (NTs) acetylcholine (ACh), the modified amino acids glutamate and γ-aminobutyric acid (GABA), and the biogenic amines dopamine, serotonin (5-HT), and histamine. In neuropsychiatry, progressive integration of dietary approaches in clinical routine made it necessary to discern the more about some of these dietary NTs. Relevant books and literature from PubMed and Scopus databases were searched for data on food sources of Ach, glutamate, GABA, dopamine, 5-HT, and histamine...
