The purpose of this study was to compare the effects of different chromatographic columns for the separation of seven flavonoids. Four different stationary phases are available, including BEH, BEH 2-EP, CSH fluorophenyl and HSS C18 SB. The analytes included calycosin, genistein, medicarpin, calycosin-7-O-β-d-glucoside, formononetin, formononetin-7-O-β-d-glucoside and liquiritigenin. The CSH fluorophenyl column was determined to be the most suitable and provided the fastest separation within 17 min using gradient elution with carbon dioxide as the mobile phase and methanol as the co-solvent...

INTRODUCTION: This study compared the effects of ad libitum consumption of different beverages and foods on fluid retention and nutrient intake following exercise. METHODS: Ten endurance trained males (mean±SD; Age=25.3±4.9years, VO2max=63.0±7.2ml·kg·min(-1)) performed four trials employing a counterbalanced, crossover design. Following 60min of exercise (matched for energy expenditure and fluid loss) participants consumed either water (W1 and W2), a sports drink (Powerade® (P)) or a milk-based liquid meal supplement (Sustagen Sport® (SS)) over a four hour recovery period...

A 58-year-old male with alcoholic liver cirrhosis and a 58-year-old male with diabetes mellitus presented with high fever and urinary retention. Prostatic abscess was diagnosed by a computed tomography scan, which showed fluid collection in the prostate in both patients. Despite systematic antibiotic therapies, urinary retention persisted even after fever diminished. They underwent prostatic abscess drainage by transurethral resection (TUR). Urinary retention was released, and the recurrence of prostatic abscess has not been observed after TUR...

BACKGROUND: Chronic Lung Allograft Dysfunction (CLAD) is the main limitation to long-term survival after lung transplantation. Although CLAD is usually not responsive to treatment, earlier identification may improve treatment prospects. METHODS: In a nested case control study, 1-year post transplant surveillance bronchoalveolar lavage (BAL) fluid samples were obtained from incipient CLAD (n = 9) and CLAD free (n = 8) lung transplant recipients. Incipient CLAD cases were diagnosed with CLAD within 2 years, while controls were free from CLAD for at least 4 years following bronchoscopy...

BACKGROUND: Heart failure is a condition in which the heart does not pump enough blood to meet all the needs of the body. Symptoms of heart failure include breathlessness, fatigue and fluid retention. Outcomes for patients with heart failure are highly variable; however on average, these patients have a poor prognosis. Prognosis can be improved with early diagnosis and appropriate use of medical treatment, use of devices and transplantation. Patients with heart failure are high users of healthcare resources, not only due to drug and device treatments, but due to high costs of hospitalisation care...

Diabetes mellitus (DM) is a chronic disease with long-term complications. Glycemic control is an important part in management of DM. The first line in treatment of type 2 DM (T2DM) is diet and life style change. Metformin is the first choice of medication in T2DM patients. Sulfonylureas have high risk of hypoglycemia. Glinides are associated with lower risk of hypoglycemia in comparison to sulfonylureas. Also α-glucosidase inhibitors decrease the polysacarides digestion in small intestine and less effective in comparison to metformin and sulfonylureas in lowering hemoglobin A1c (HbA1c)...

The past decade has witnessed great advances in the treatment of chronic myeloid leukemia (CML), brought about in large part by the development of BCR-ABL tyrosine kinase inhibitors (TKIs). Bosutinib joins the armamentarium of approved TKIs for the treatment of chronic phase (CP), accelerated phase (AP), and blast phase (BP) Philadelphia chromosome (Ph)-positive CML resistant to or intolerant of prior therapy. Bosutinib has an adverse-event (AE) profile distinct from that of other TKIs. Diarrhea is the predominant toxicity associated with bosutinib treatment; other commonly reported nonhematologic AEs include rash and liver enzyme elevations...

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are a novel category of oral antidiabetic drugs that inhibit renal glucose reabsorption and increase renal glucose excretion, thus lowering plasma glucose levels. This unique mechanism of SGLT2i action is insulin independent, thus improving glycemic control without promoting hypoglycemia in the absence of exogenously administered insulin. METHODS: The present narrative review addresses the putative associations between SGLT2i and several cardiovascular (CV) and microvascular risk factors, as well as their effects on cardiac and renal function...

OBJECTIVE: Due to limited economic conditions, we tried to provide "fitted" dialysis doses instead of the doses recommended by the international guidelines to the individual patients. In the present cross-sectional study, we studied the dialysis adequacy and nutritional status of 5 peritoneal dialysis patients who had a low dialysis dose (2 bags, 4,000 mL/day). METHODS: The 3-day dietary records were reviewed to calculate patients' energy, protein, and nitrogen intake (NI)...

RATIONALE: Refined cottonseed oil has widespread applications in the food and chemical industries. Although the major lipids comprising cottonseed oil (triacylglycerols) are well known, there are many diverse lipid species in cotton seeds that occur at much lower levels and have important nutritional or anti-nutritional properties. METHODS: The lipid technical samples were prepared in chloroform. The biological samples were extracted using a mixture of isopropanol:chloroform:H2 O (2:1:0...

Early innovations in the delivery of peritoneal dialysis (PD) markedly improved its acceptability and lowered peritonitis rates. The standard osmotic agent was, and continues to be dextrose, an agent that is not ideal as it is readily absorbed. The development of icodextrin-containing dialysis fluid has allowed a long dwell time to provide more effective ultrafiltration. The development of a smaller, more easily used automated cycler, led to an increase in the proportion of patients on the cycler as opposed to CAPD...

Heart failure is one of the leading causes of death worldwide. It is a complex clinical syndromethat includes fatigue, dyspnea, exercise intolerance, and fluid retention. Changes in myocardial structure, electrical conduction, and energy metabolism develop with heart failure, leading to contractile dysfunction, increased risk of arrhythmias, and sudden death. Hypertensive heart disease is one of the key contributing factors of cardiac remodeling associated with heart failure. The most commonly-used animal model mimicking hypertensive heart disease is created via surgical interventions, such as by narrowing the aorta...

Male factor infertility is involved in almost half of all infertile couples. Lack of the ejaculated sperm due to testicular malfunction has been reported in 6-10% of infertile, a condition named non-obstructive azoospermia (NOA). In this study, we investigated untargeted metabolomic profiling of the seminal plasma in NOA men using gas chromatography-mass spectrometry (GC-MS) and advance chemometrics. In this regard, the seminal plasma fluids of 11 NOA men with TESE-negative (AZN), 9 NOA men with TESE-positive (AZP) and 10 fertile (F) healthy men (as a control group) were collected...

A particle exposure assessment based on the dose deposited in the lungs would be the gold standard for the evaluation of any resulting health effects. Measuring particles in exhaled breath condensate (EBC)-a matrix containing water and airway lining fluid-could help to evaluate particle retention in the lungs. This study aimed to (1) validate a nanoparticle tracking analysis (NTA) method for determining the particle number concentration and their hydrodynamic size distribution in EBC, and (2) apply this method to EBC collected from workers exposed to soapstone (n = 55) or quartz dust (n = 12) and controls (n = 11)...

INTRODUCTION: The success of antiretroviral therapy has led to dramatic changes in causes of morbidity and mortality among U.S. Veterans with human immunodeficiency virus (HIV). Among the 25,000 Veterans treated for HIV, 70% are over age 50 and the rate of obesity has doubled in this population. Veterans with HIV have a 50% increased risk of myocardial infarction yet have limited presence in prevention-related programs designed to lower cardiovascular disease risk. METHODS: This mixed methods study (focus groups, Schwarzer and Renner physical activity, and nutrition self-efficacy questionnaires) was used to explore factors related to health behavior and identify barriers that overweight Veterans with HIV face in enrolling in the MOVE weight management program...

When an SFC column is operated in a traditional oven with forced air at low pressures near the critical temperature, severe efficiency losses can occur. The mobile phase cools as it expands along the column, forming axial and radial temperature gradients. In this study we present a simple model based on a virtual fluid to predict the conditions which lead to the onset of efficiency loss. The model shows that the Joule-Thomson coefficient is an important factor leading to efficiency loss in packed columns under forced air conditions...
