This study was aimed to evaluate the relationship between normal serum uric acid (SUA) level and metabolic syndrome (MetS) risk. This cross-sectional study involved 1914 subjects with MetS and 3 659 healthy controls aged 18-79 years. All participants filled out questionnaires and underwent physical examination and blood sample collection for biochemical examination. Demographic and clinical characteristics data were analyzed by t-test or chi-squared test. Normal SUA levels were divided into quartiles. Associations between quartiles of normal SUA level and the risk of MetS were explored using logistic regression analysis and receiver operating characteristic (ROC) curve analysis...

Alterations in birth weight impact postnatal outcome and adult metabolic health. Therefore, fetal growth regulation is crucial for preventing chronic metabolic diseases. Leptin has been suggested to play an important role in placental and fetal growth, albeit its specific mechanisms of action have not been elucidated. The aim of this study was to analyze leptin concentrations in placenta, cord blood, and maternal blood of SGA, AGA, and LGA (small, adequate and large for gestational age, respectively) newborns, as well as placental leptin receptor (LEPRa and LEPRb) protein expression...

Infertility affects millions of couples worldwide resulting in distress and depression. In the past several decades, in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) have been developed with high efficiency and success rate. The possible effects of gonadotropin administration on follicular metabolism have been discussed but the outcomes remain controversial. The aim of this study was to identify whether serum progesterone on the day of human chorionic gonadotropin (hCG) administration and the ratio of serum progesterone and the number of oocyte retrieved (P/O) had a predictive role for the outcomes of IVF/ICSI...

Macular edema is one of the most common causes of permanent vision loss in patients with uveitis. The current understanding of water balance and metabolism within the retina has given us better insight into the mechanisms underlying macular edema arising from both acute and chronic inflammation. Uveitic macular edema (UME) occurs when the equilibrium between water influx and efflux is lost, and more importantly when compensatory mechanisms are overwhelmed. While in the acute setting, control of inflammation can reestablish homeostasis, chronic inflammation can lead to alternate pathways to establish a water balance...

Macular edema is most often clinically defined as an accumulation of serous fluid within the neurosensory retina with increased thickness of the central retina. In exudative age-related macular degeneration the leakage of fluid from the choroidal new vessels may be the origin of macular edema. Their abnormal permeability and the inflammatory reaction are mechanisms involved in this accumulation of fluid, which occurs in all layers. Cystoid macular edema is more often associated with subepithelial occult choroidal neovascularization (CNV) than it is with pre-epithelial classic CNV...

The macula is predisposed to edema in various retinal conditions, even when the insult is remote from the macula. The various factors that may predispose the macula to edema include high metabolic activity, radial arrangement of the Henle's layer, lack of inner layers at the fovea, and lack of blood supply at the fovea. The edema is most pronounced in the outer plexiform layer (Henle's layer). Alteration in the blood-retinal barrier and ischemia cause disturbances in vascular permeability as well as with the function of Müller cells...

Cri-du-chat syndrome (CDCS) is a rare innate disease attributed to chromosome 5p deletion characterized by a cat-like cry, craniofacial malformation, and altered behavior of affected children. Metabolomic analysis and a chemometric approach allow description of the metabolic profile of CDCS as compared to normal subjects. In the present work, UHPLC/MS was employed to analyze blood samples withdrawn from CDCS carriers (n=18) and normal parental subjects (n=18), all aged 0-34 years, aiming to set up a representative CDCS profile constructed from 33 targeted amino acids and biogenic amines...

Generation of free radicals through incomplete reduction of oxygen during ischemia/ reperfusion is well-described. On the other hand, molecular hydrogen (H<sub>2</sub>) reduces oxidative stress due to its ability to react with strong oxidants and easily penetrate cells by diffusion, without disturbing metabolic redox reactions. This study was designed to explore cardioprotective potential of hypoxic postconditioning (HpostC) against ischemia/reperfusion (30-min global I/120-min R) in isolated rat hearts using oxygen-free Krebs-Henseleit buffer (KHB)...

The 7-oxysterols are recognised as strong enhancers of inflammatory processes in foamy macrophages. Atheroma-relevant 7-oxysterol mixtures induce a mixed type of cell death in macrophages, and trigger cellular oxidative stress responses, which mimic oxidative exposures observed in atherosclerotic lesions. However, the macrophage proteome has not previously been determined in the 7-oxysterol treated cell model. The aim of the present study was to determine the specific effects of an atheroma-relevant 7-oxysterol mixture on human macrophage proteome...

Honeybees (Apis mellifera) are constantly subjected to many biotic stressors including parasites. This study examined honeybees infected with Nosema ceranae (N. ceranae). N. ceranae infection increases the bees energy requirements and may contribute to their decreased survival. RNA-seq was used to investigate gene expression at days 5, 10 and 15 Post Infection (P.I) with N. ceranae. The expression levels of genes, isoforms, alternative transcription start sites (TSS) and differential promoter usage revealed a complex pattern of transcriptional and post-transcriptional gene regulation suggesting that bees use a range of tactics to cope with the stress of N...

OBJECTIVES: Preeclampsia is divided into early-onset (delivery before 34 weeks of gestation) and late-onset (delivery at or after 34 weeks) subtypes, which may rise from different etiopathogenic backgrounds. Early-onset disease is associated with placental dysfunction. Late-onset disease develops predominantly due to metabolic disturbances, obesity, diabetes, lipid dysfunction, and inflammation, which affect endothelial function. Our aim was to use cluster analysis to investigate clinical factors predicting the onset and severity of preeclampsia in a cohort of women with known clinical risk factors...

Targeted mutant models are common in mechanistic toxicology experiments investigating the absorption, metabolism, distribution, or elimination (ADME) of chemicals from individuals. Key models include those for xenosensing transcription factors and cytochrome P450s (CYP). Here we investigated changes in transcript levels, protein expression, and steroid hydroxylation of several xenobiotic detoxifying CYPs in constitutive androstane receptor (CAR)-null and two CYP-null mouse models that have subfamily members regulated by CAR; the Cyp3a-null and a newly described Cyp2b9/10/13-null mouse model...

BACKGROUND: Evidence-based plastic surgery guidelines support the effectiveness of once-daily enoxaparin prophylaxis. Despite prophylaxis, one in 25 highest risk patients has a venous thromboembolism event. The authors examined the pharmacodynamics of standard enoxaparin doses in plastic surgery patients to examine whether patient-level factors predict enoxaparin metabolism, whether inadequate enoxaparin dose predicts downstream venous thromboembolism events, and whether a pharmacist-driven dose-adjustment protocol was effective...

BACKGROUND: Gold nanostars are unique nanoplatforms that can be imaged in real time and transform light energy into heat to ablate cells. Adipose-derived stem cells migrate toward tumor niches in response to chemokines. The ability of adipose-derived stem cells to migrate and integrate into tumors makes them ideal vehicles for the targeted delivery of cancer nanotherapeutics. METHODS: To test the labeling efficiency of gold nanostars, undifferentiated adipose-derived stem cells were incubated with gold nanostars and a commercially available nanoparticle (Qtracker), then imaged using two-photon photoluminescence microscopy...

BACKGROUND: Metabolic syndrome is characterized by a pronounced sympathetic overactivity as documented by the marked increase in muscle sympathetic nerve traffic (MSNA) as well as in plasma norepinephrine values reported in this condition. Whether and to what extent heart rate (HR) reflects the abovementioned adrenergic alterations in metabolic syndrome remains largely undefined. It is also undefined the validity of the abovementioned adrenergic markers in reflecting the main features of the metabolic syndrome...

Although hyperglycemia is common in neonates, especially preterm infants, a diagnosis of neonatal diabetes mellitus (NDM) is rarely made. NDM can be permanent (45%), transient (45%) or syndromic (10%). Of the 95% of identifiable mutations for NDM, methylation defects in 6q24, KCNJ11, ABCC8, and INS account for the majority. Two cases of transient NDM in extremely preterm, 24 weeks' gestational age (GA) triplets, due to a missense mutation c.685G>A in the KCNJ11 gene are presented. Both patients were successfully transitioned from insulin to Glyburide (Glibenclamide) at 2 months of age...
