Low-Energy Dense Potato- and Bean-Based Diets Reduce Body Weight and Insulin Resistance: A Randomized, Feeding, Equivalence Trial
AbstractWe evaluated the effect of diets low in energy density (1 kcal/g) and high in either potatoes (Potato) or pulses (Bean) on blood glucose control in participants with insulin resistance. We hypothesized that the Potato and Bean diets would have equivalent effects. This was an 8-week randomized, parallel design, controlled feeding study comparing Potato and… Continue reading Low-Energy Dense Potato- and Bean-Based Diets Reduce Body Weight and Insulin Resistance: A Randomized, Feeding, Equivalence Trial
Dysregulated amino acid sensing drives colorectal cancer growth and metabolic reprogramming leading to chemoresistance
Background and AimsCRC is a devastating disease highly modulated by dietary nutrients. mTORC1 contributes to tumor growth and limits therapy responses. Growth factor signaling is a major mechanism of mTORC1 activation. However, compensatory pathways exist to sustain mTORC1 activity following therapies that target oncogenic growth factor signaling. Amino acids potently activate mTORC1 via amino acid… Continue reading Dysregulated amino acid sensing drives colorectal cancer growth and metabolic reprogramming leading to chemoresistance
Mono-(2-ethyl-5-hydroxyhexyl) phthalate promotes uterine leiomyoma cell survival through tryptophan-kynurenine-AHR pathway activation
Uterine leiomyomas (or fibroids) represent the most common tumor affecting up to 80% of reproductive-age women. Epidemiological studies consistently indicate a positive association between exposure to endocrine-disrupting phthalates and leiomyoma risk; however, the underlying mechanisms remain unclear. Here, we demonstrate that the ubiquitous environmental pollutant mono-(2-ethyl-5-hydroxyhexyl) phthalate [MEHHP, the major metabolite of di-(2-ethylhexyl) phthalate] promotes… Continue reading Mono-(2-ethyl-5-hydroxyhexyl) phthalate promotes uterine leiomyoma cell survival through tryptophan-kynurenine-AHR pathway activation
Effects of a Low-Carbohydrate Dietary Intervention on Hemoglobin A1cA Randomized Clinical Trial
Importance Low-carbohydrate diets decrease hemoglobin A1c (HbA1c) among patients with type 2 diabetes at least as much as low-fat diets. However, evidence on the effects of low-carbohydrate diets on HbA1c among individuals with HbA1c in the range of prediabetes to diabetes not treated by diabetes medications is limited.Objective To study the effect of a behavioral intervention promoting a low-carbohydrate diet… Continue reading Effects of a Low-Carbohydrate Dietary Intervention on Hemoglobin A1cA Randomized Clinical Trial
Association between hypercholesterolemia and mortality risk among patients referred for cardiac imaging test: Evidence of a “cholesterol paradox?”
Aim: Some observational studies have observed a lower, rather than higher, mortality rate in association with hypercholesterolemia during follow-up of patients after cardiac stress testing. We aim to assess the relationship of hypercholesterolemia and other CAD risk factors to mortality across a wide spectrum of patients referred for various cardiac tests.Methods and results: We identified four cardiac… Continue reading Association between hypercholesterolemia and mortality risk among patients referred for cardiac imaging test: Evidence of a “cholesterol paradox?”
A dietary intervention for vasomotor symptoms of menopause: a randomized, controlled trial
Objective Postmenopausal vasomotor symptoms disrupt quality of life. This study tested the effects of a dietary intervention on vasomotor symptoms and menopause-related quality of life.Methods Postmenopausal women (n = 84) reporting at least two moderate-to-severe hot flashes daily were randomly assigned, in two successive cohorts, to an intervention including a low-fat, vegan diet and cooked soybeans (½ cup [86… Continue reading A dietary intervention for vasomotor symptoms of menopause: a randomized, controlled trial
Zinc ions prevent α-synuclein aggregation by enhancing chaperone function of human serum albumin
Metal ions present in cellular microenvironment have been implicated as drivers of aggregation of amyloid forming proteins. Zinc (Zn2+) ions have been reported to directly interact with α-synuclein (AS), a causative agent of Parkinson's disease and other neurodegenerative diseases, and promote its aggregation. AS is a small intrinsically disordered protein (IDP) i.e., understanding molecular factors… Continue reading Zinc ions prevent α-synuclein aggregation by enhancing chaperone function of human serum albumin
Dietary intake of thiamine and riboflavin in relation to severe headache or migraine: A cross-sectional survey
AbstractObjectiveThe purpose of this study was to identify the prevalence of severe headache or migraine and the association between dietary thiamine and riboflavin intake with headache history using a large, nationally representative population sample.BackgroundSevere headache and migraine are common and disabling neurological disorders worldwide. Previous studies revealed that the B vitamin group, as an important… Continue reading Dietary intake of thiamine and riboflavin in relation to severe headache or migraine: A cross-sectional survey
