Objectively measured eating behaviors and their relation to food intake in school and hospital settings
(Inst för biovetenskaper och näringslära / Dept of Biosciences and Nutrition, 2021-05-28)Introduction. The measurement of food intake (what and how much we eat and drink) is of great importance due to its involvement in three great challenges facing humanity: 1) obesity/overnutrition, 2) undernutrition and 3) ... -
PAK4 in organ development and cancer initiation
(Inst för biovetenskaper och näringslära / Dept of Biosciences and Nutrition, 2021-05-28)Tumors are complex organs with a unique ecosystem containing tumor cells entangled with various infiltrating cells. Tumors have distinct signaling signatures, which confers upon it the ability to grow in the primary host ... -
Estrogen receptor beta transcriptional regulation : a potential mechanism for colon cancer prevention
(Inst för biovetenskaper och näringslära / Dept of Biosciences and Nutrition, 2021-05-07)Colorectal cancer (CRC) is the third leading cause of death from cancer in both men and women in the Western world.
