BACKGROUND: Dry immersion (DI), a ground-based model of microgravity previously used in Russia, has been recently implemented in France. The aim of this study was to analyze early events in a short-term DI model in which all conditions are met to investigate who is first challenged from osteo- or adipo-kines and to what extent they are associated to insulin-regulating hormones. METHODS: Twelve healthy men were submitted to a 3-day DI. Fasting blood was collected during pre-immersion phase for the determination of the baseline data collection (BDC), daily during DI (DI24h, DI48H and DI72h), then after recovery (R+3h and R+24h)...

BACKGROUND: Subclinical hypothyroidism (SCH) is defined as high TSH and normal thyroxine. Data on the effects of early substitution by levothyroxine on psychophysical health in SCH are still not consistent enough to support its introduction. METHODS: Clinical parameters, biochemical data and quality of life (Short Form 36 questionnaire) were measured before the intervention and 3 months after the euthyroid state had been achieved in SCH patients. RESULTS: Significant reduction in body weight (p=0...

Cell migration depends on a combination of the cell's intrinsic capacity to move and the proper interpretation of external cues. This multistep process enables leukocytes to travel long distances in organs in just a few hours. This fast migration is partly due to the leukocytes' high level of plasticity, which helps them to adapt to a changing environment. Here, we review recent progress in understanding the mechanisms used by leukocytes to move rapidly and efficiently in intricate anatomical landscapes. We shall focus on specific cytoskeletal rearrangements used by neutrophils and dendritic cells to migrate within confined environments...

The cell composition of bronchoalveolar lavage fluid (BAL) is an important indicator of airway inflammation. It is commonly determined by cytocentrifuging leukocytes on slides, then staining, identifying, and counting them as eosinophils, neutrophils, macrophages, or lymphocytes according to morphological criteria under light microscopy, where it is not always easy to distinguish macrophages from lymphocytes. We describe here a one-step, easy-to-use, and easy-to-customize 8-color flow cytometric method for performing differential cell count and comparing it to morphological counts on stained cytospins...

Adrenal incidentalomas (AIs) are usually discovered incidentally after imaging unrelated to adrenal glands. We aimed to evaluate standard risk factors for systemic atherosclerosis and echocardiographic changes in patients with nonfunctioning AIs and compare them with normal subjects. We evaluated 70 patients diagnosed with AIs and 51 healthy controls. Mean levels were determined for HbA1c, LDL, uric acid, fasting plasma insulin, HOMA, and neutrophil-to-lymphocyte ratio (NLR), and these values were found to be significantly higher in the patients than the controls...

OBJECTIVES: To detect whether the mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are contributing factors in the diagnosis and severity of sleep apnea in obese children. INTRODUCTION: Obesity is a public health problem, and its prevalence increases daily. Although PSG is the gold standard test in the investigation of sleep apnea, the application of this test requires equipment, personnel, time, and cost. There is no simple laboratory test for diagnosing and determining the severity of sleep apnea...

PURPOSE: Non-alcoholic fatty liver disease is highly associated with morbidity and mortality in population. Although studies have already demonstrated that the immune response plays a pivotal role in the development of non-alcoholic fatty liver disease, the comprehensive regulation is unclear. Therefore, present study was carried out to investigate the non-alcoholic fatty liver disease development under neutrophil depletion. METHODS: To achieve the aim of the study, C57BL/6 J mice were fed with high fat diet for 6 weeks before treated with neutrophil deplete antibody 1A8 or isotype control (200 μg/ mouse every week) for another 4 weeks...

Shift workers suffer from a constellation of symptoms associated with disruption of circadian rhythms including sleep abnormalities, and abnormal hormone secretion (e.g. melatonin, cortisol). Recent, but limited, evidence suggests that shift workers have elevated levels of circulating white blood cells (WBCs) compared to their day working counterparts. Interestingly, recent reviews highlight the strong linkage between the immune system and circadian rhythms which includes, but is not limited to, circulating cell populations and functions...

Obesity is characterized by chronic low-grade inflammation driven by activation and tissue infiltration of circulating leukocytes. Although exercise has anti-inflammatory effects, the impact of exercise on mediators of leukocyte migration is unclear. PURPOSE: To determine the impact of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT), in the absence of weight/fat loss, on circulating chemokines and leukocyte chemokine receptors. METHODS: Thirty-seven inactive obese adults were randomized to 2 wk (10 sessions) of HIIT or MICT with fasting blood samples collected before and after training...

Introduction. The neutrophil-lymphocyte ratio (NLR) is a significant systemic predictor of cardiovascular disease (CVD). The coronary artery calcium score (CACS) reflects coronary artery calcification and is an independent risk factor for coronary artery stenosis. In the present study, we explored the relationship between the NLR and CACS in terms of subclinical inflammation and coronary artery calcification. Materials and Methods. We evaluated males and females who did not have CVD, diabetes, high blood pressure, or high fasting blood sugar levels...
