Alternate day fasting

Shannon N Zenk, Stephen A Matthews, Amber N Kraft, Kelly K Jones
This study examined the number of days of global positioning system (GPS) monitoring needed to measure attributes of an individual's routine activity space. Multiple alternative activity space representations (cumulative, mean daily), measures (kernel density, route buffer, convex hull), and attributes (area size, supermarkets, fast food restaurants, parks) were examined. Results suggested wide variability in required GPS days to obtain valid estimates of activity space attributes (1-23 days). In general, fewer days were needed for mean daily activity space representations, kernel density measures, and densities of environmental exposures (vs...

Autotrophic denitrification with sulfur is an underexplored alternative to heterotrophic denitrification to remove nitrate from wastewater poor in organics. The application on ion exchange regeneration water (19.4-32.1 mS cm-1 ) is novel. Three fixed bed reactors were tested at 15 °C for >4 months, inoculated with activated sludge from sewage treatment. All were fast in start-up (<10 days) with high performance (94 ± 2% removal efficiency). pH control with NaOH rendered higher nitrate removal rates than limestone addition to the bed (211 ± 13 vs...

Exhaled breath condensate (EBC) is receiving increased attention as a novel, entirely non-invasive technique for collecting biomarker samples. This increased attention is due to the fact that EBC is simple, effort independent, rapid, can be repeated frequently, and can be performed on young children and patients suffering from a variety of diseases. By having a subject breathe tidally through a cooling system for 15-20 min, a sufficient amount of condensate is collected for analysis of biomarkers in clinical studies...

Herein, we reveal a double emulsion method combining the sol-gel method to prepare poly(lactic-co-glycolic acid) microspheres with different porous structures for sequential release of two types of biomolecules. By controlling the ripening time of the emulsion, multiple interconnected chambers could be easily chosen to be either embedded in microspheres or opened to the surface. These two types of microspheres exhibited different kinetics for the release of both small molecules and proteins, where the release from microspheres with open pores (5 day over 90%) was much faster than the release from microspheres with embedded pores (25 day over 90%)...

OBJECTIVE: Pain in chronic venous ulcers (CVUs) notably increases with the usual cleaning of the wound. Chronic pain is usually poorly controlled even with the multiple analgesic treatments available. Analgesics can have different serious adverse effects and medical interactions in old patients with several comorbidities. This study reports the efficacy and safety of topical sevoflurane for treatment of pain in CVUs. METHODS: We report a descriptive and retrospective study of 30 patients older than 65 years with painful CVUs refractory to conventional analgesic treatments...

The neural bases of cognition may be greatly informed by relating temporally defined developmental changes in behavior with concurrent alterations in neural function. A robust improvement in performance in spatial learning and memory tasks occurs at 3 wk of age in rodents. We reported that the developmental increase of spontaneous alternation in a Y-maze was related to changes in temporal dynamics of fast glutamatergic synaptic transmission in the hippocampus. We also showed that, during allothetic behaviors in the Y-maze, network oscillation power increased at frequency bands known to support spatial learning and memory in adults...

The aim of the present work was to investigate the potential of microemulsions for the buccal administration of triamcinolone acetonide. Microemulsions were developed by the construction of pseudoternary phase diagrams, using the aqueous titration method. Among all microemulsions prepared and tested for stability, three were selected and submitted to characterization and in vitro permeation/retention experiments, using pig esophageal epithelium, an accepted model of the buccal mucosa. Furthermore, one microemulsion was added of excipients (stearylamine, CTAB and chitosan) able to alter the charge of droplets...

The goal of childhood obesity lifestyle interventions are to positively change body composition, however it is unknown if interventions also modulate factors that are related to energy intake. This study aimed to examine changes in eating behaviors and plasma leptin concentrations in overweight and obese children participating in a 1-year family-centered lifestyle intervention. Interventions were based on Canadian diet and physical activity (PA) guidelines. Children were randomized to 1 of 3 groups: Control (Ctrl; no intervention), Standard treatment (StnTx: 2 servings milk and alternatives/day (d), 3x/wk weight-bearing PA), or Modified treatment (ModTx: 4 servings milk and alternatives/day; daily weight-bearing PA)...

BACKGROUND: Prior studies have shown that intermittent fasting is capable of producing improvements in body weight and fasted health markers. However, the extent to which intermittent fasting incurs compensatory changes in the components of energy balance and its impact on postprandial metabolism are yet to be ascertained. METHODS: A total of 30-36 lean participants and 30-36 overweight/obese participants will be recruited to provide two separate study groups who will undergo the same protocol...

PURPOSE: The capacity to match carbohydrate (CHO) oxidation with CHO availability (deemed metabolic flexibility (MetFlex)) may be important for type 2 diabetes prevention. In adults, impaired MetFlex is associated with insulin resistance (IR), which can be improved with as little as 7 days of exercise. Whether this occurs similarly in children is unknown. We hypothesized 7 consecutive days of exercise would improve MetFlex and IR in children with obesity. METHODS: Twelve children (8 boys, 4 girls) completed 2 study visits before (PRE) and 2 study visits after (POST) exercise training...

OBJECTIVE: The most productive methods of recruitment for a videogame for health (G4H) trial are not known. Success or failure of recruitment methods has been reported for a variety of clinical trials, but few specifically for G4H trials. This study's goal was to recruit 444 overweight or obese (body mass index percentile between the 84.5th-99.4th percentiles) children between the ages of 10-12 years. The article reports the results of different methods of participant recruitment. MATERIALS AND METHODS: Participants had to agree to three fasting blood samples (baseline, immediately after, and 2 months later); be willing to wear an accelerometer for 7 days at each assessment; read and speak English fluently (because the games were in English); have no history of any condition that would affect what he/she could eat or how much physical activity he/she could get; and have an eligible home computer purchased in the last 5 years with high-speed internet...

Intermittent fasting (IF) was suggested to be a powerful nutritional strategy to prevent the onset of age-related neurodegenerative diseases associated with compromised brain bioenergetics. Whether the application of IF in combination with a mitochondrial insult could buffer the neurodegenerative process has never been explored yet. Herein, we defined the effects of IF in C57BL/6J mice treated once per 24 h with rotenone (Rot) for 28 days. Rot is a neurotoxin that inhibits the mitochondrial complex I and causes dopamine neurons degeneration, thus reproducing the neurodegenerative process observed in Parkinson's disease (PD)...
