3% in men vs. 7.4% in women, p=0.10), but the prevalence of iron deficiency was significantly higher in women (1.3% vs. 17.9%, p<0.001). The prevalences of copper (2.3%) and selenium (3.2%) deficiencies were low, and none of the participants had vitamin B12 or magnesium deficiency.

There were high prevalences of vitamin D, folate, vitamin B1, and iron deficiencies in bariatric patients in Korea. Nutritional deficiencies should be corrected prior to surgery to prevent subsequent further depletion. Routine analysis of vitamin B12, magnesium, copper, and selenium before surgery should be considered and studied in more detail.

Furthermore, the measuring process is very rapid. These characteristics of chlorophyll fluorescence measurements make them a suitable tool to screen mutants of photosynthesis-related genes. Furthermore, it has been shown that genes with a wide range of functions can be also analyzed by chlorophyll fluorescence through metabolic interactions. In this short review, we would like to first introduce the basic principle of the chlorophyll fluorescence measurements, and then explore the advantages and limitation of various screening methods. The emphasis is on the possibility of chlorophyll fluorescence measurements to screen mutants defective in metabolisms other than photosynthesis.Experimental and theoretical studies have provided structural information regarding the shift from inactive to active EGFR, throughout which both conformations are linked via binding to specific tyrosine kinase inhibitors. For HER2, an intermediate active-inactive receptor conformation is present in the PDB, which has been co-crystallized with tak-285. The affinity of HER2 in monomeric state to tak-285 has been previously reported. However, the lack of structural knowledge of HER2 limits our capacity to understand whether tak-285, or other known HER2 inhibitors, selectively bind active, inactive, or intermediate forms of HER2. To elucidate mechanisms by which tak-285 binds to HER2, we first obtained information regarding the structural features of the active state of HER2 via microsecond MD simulations from the crystallized intermediate structure previously determined. Based on these HER2 conformers, together with the inactive HER2 conformer obtained in a previous study, we used docking and MD simulations coupled to MMGBSA approach to assess binding of tak-285 and lapatinib, known HER2/EGFR dual inhibitors, to HER2. Structural and energetic studies revealed that tak-285 binds with a greater affinity than lapatinib to active and intermediate active-inactive forms of HER2. This is in accordance with experimental findings that showed the tak-285 inhibitor has increased activity relative to lapatinib in breast cancer cell lines.A considerable body of evidence has been accumulated showing the interrelationship between zinc and the plasma thyroid hormone (TH) distributor protein, transthyretin (TTR). TTR is a multi-functional protein, which emerged from 5-hydroxyisourate hydrolase (HIUHase) by neo-functionalization after gene duplication during early chordate evolution. HIUHase is also a zinc-binding protein. Most biochemical and molecular biological findings have been obtained from mammalian studies. However, in the past two decades, it has become clear that fish TTR displays zinc-dependent TH binding. After a brief introduction on plasma zinc, THs and their binding proteins, this review will focus on the role of zinc in TTR functions of various vertebrates. In particular primitive fish TTR has an extremely high zinc content, with an increased number of histidine residues which are involved in TH binding. However, zinc-dependent TH binding may have been gradually lost from TTRs during higher vertebrate evolution. Although human TTR has a low zinc content, zinc plays an essential role in TTR functions other than TH binding the stability of TTR-holo retinol binding protein 4 (holoRBP4) complex, TTR amyloidogenesis, the sequestration of amyloid β (Aβ) fibrils and cryptic proteolytic activity. The interaction of TTR with metallothioneins may be a critical step in the exertion of some of these functions. Evolutionary and physiological insights on zinc-dependent functions of TTRs are also discussed.Hepatitis B (HBV) is endemic in Haiti, therefore Haitian immigrants should be screened to identify and link affected individuals to care. Current screening approaches are ineffective. We assessed the acceptability and feasibility of home-based screening among Haitian immigrants using community health workers (CHWs). We recruited participants exiting a pragmatic trial evaluating strategies to improve care delivery (NCT02970136). Participants completed an acceptability questionnaire. Blood drawn by CHWs at participants' homes or community sites was tested for hepatitis B surface antigen, hepatitis B surface antibody and hepatitis B core antibody. Of 60 participants, 59 found screening acceptable; 53 had blood drawn. Of those, 45.3% had HBV previously, 49.1% remained susceptible and 5.7% were vaccinated. Respondents cited various reasons community members might find screening unacceptable. The high prior HBV rate highlights the need for effective outreach programs. Home-based HBV screening was both acceptable and feasible among Haitian immigrants.

We report the 48-week results of an ongoing study to assess the efficacy and safety of switching older people with HIV to bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF).

This was a 96-week, phase 3b, open-label, single-arm study (GS-US-380-4449; NCT03405935). Virologically suppressed individuals aged ≥ 65years receiving elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide or a tenofovir disoproxil fumarate-based regimen were switched to B/F/TAF. Primary endpoint was the percentage of participants with HIV-1 RNA < 50 copies/ml at week 24.

Eighty-six participants (median age 69 [range 65-80] years; 87% male; 95% white) were enrolled and treated in five European countries. Rates of virologic suppression were 97.7% at week 24 and 90.7% at week48; none had HIV-1 RNA ≥ 50 copies/ml, and 100% had virologic suppression by missing = excluded analysis at both time points. No treatment-emergent resistance was observed. There were no grade 3-4 study drug-related adverse events (AEs) or study drug-related serious AEs or deaths. Three AEs led to premature discontinuation; one (moderate abdominal discomfort) was attributed to the study drug by the investigator. At week 48, median changes from baseline in weight and estimated glomerular filtration rate were + 0.1kg (interquartile range [IQR] - 1.0, 2.3) and - 6.0ml/min (IQR - 10.2, 0.0), respectively. There were no clinically relevant changes from baseline to week 48 in fasting lipid parameters. Treatment satisfaction improved, and health-related quality of life was maintained from baseline through week 48. Median adherence to the study drug was 98.6% (IQR 96.0, 100).

Switching to B/F/TAF was effective and well tolerated through 48weeks in virologically suppressed adults aged ≥ 65years.

It has been assumed that this intrinsic stochasticity is purely additive (position independent) in quiescent (unperturbed) swarms. Here, I identify the hallmarks of intrinsic multiplicative (position dependent) stochasticity and show that they are evident in quiescent laboratory swarms of the non-biting midge Chironomus riparius. In accordance with theoretical expectations, the smallest well-documented laboratory swarms (containing between 14 and 46 individuals) are found to have q-Gaussian density profiles with [Formula see text] 1, whereas larger laboratory swarms have Gaussian ([Formula see text]1) density profiles. I show that these newly identified states are analogous to interstellar clouds and thereby extend a long-standing analogy between insect swarms and self-gravitating systems. Smaller laboratory swarms have been observed and are predicted to be gas-like, filling the available space rather than occupying just a small proportion of it. The new results unify laboratory swarms with wild swarms. Unlike laboratory swarms, wild swarms must contend with environmental (extrinsic) noise and have density profiles that are accurately represented by q-Gaussians with [Formula see text] 1. Finally, it is shown how intrinsic multiplicative noise allows for the nucleation of swarms away from prominent visual features (basins of attraction) known as swarm markers.The global human population has recently experienced an increase in life expectancy with a mounting concern about the steady rise in the incidence of age-associated chronic diseases and socio-economic burden. Calorie restriction (CR), the reduction of energy intake without malnutrition, is a dietary manipulation that can increase health and longevity in most model organisms. However, the practice of CR in day-to-day life is a challenging long-term goal for human intervention. Recently, daily fasting length and periodicity have emerged as potential drivers behind CR's beneficial health effects. Numerous strategies and eating patterns have been successfully developed to recapitulate many of CR's benefits without its austerity. These novel feeding protocols range from shortened meal timing designed to interact with our circadian system (e.g., daily time-restricted feeding) to more extended fasting regimens known as intermittent fasting. Here, we provide a glimpse of the current status of knowledge on different strategies to reap the benefits of CR on metabolic health in murine models and in humans, without the rigor of continuous reduction in caloric intake as presented at the USU State of the Science Symposium.

There is a higher prevalence of lifestyle-related diseases among Irish farmers than the general adult population. Lifestyle interventions that increase physical activity and improve dietary patterns have been associated with reduced chronic disease risk and improved quality of life among high-risk populations. The impact of lifestyle interventions among Irish farmers is unknown.

To assess the effectiveness of a community-based intervention on farmer health, cardiovascular fitness, lower limb strength endurance, and dietary intake.

A 6-week physical activity and lifestyle education intervention involving two 60-min circuit-based exercise training sessions and one 60-min health education workshop per week was implemented. Pre- and post-measurements included total body weight, body fat percentage, lean muscle mass, resting blood pressure, fasting blood glucose, cholesterol, triglycerides, cardiovascular fitness, lower limb strength, perceived physical and mental health, and dietary intake.

Thirty farmers completed the intervention giving an adherence rate of 75%.
