The aim of the research. Assessing the impact of chronic hyperglycemia on the parameters of the protein, lipid metabolism and platelet-coagulation haemostasis in patients with active phase of acromegaly. Materials and methods: The research included 58 patients with the active phase of acromegaly (36 women and 28 men), median age 50 (43, 57) years, disease duration 9.0 (5.0, 15.0) years, 26 of whom had verified diabetes mellitus. Results: Biochemical parameters and parameters of haemostasis in patients with active phase of acromegaly with normoglycemia differed from the control group by higher levels of total cholesterol, high-density lipoproteins, an increase in the average volume of platelet aggregation and enhancement of their function. The presence of diabetes mellitus was accompanied by the increase in concentration of total cholesterol, triglycerides, decrease in high-density lipoproteins, and increase in fibrinogen concentration, soluble fibrin-monomeasured complexes, as well as reduction of disaggregation properties of platelets and enhancement of ejection reactions. Conclusion: The presence of diabetes mellitus with acromegaly can be regarded as a significant risk factor for atherogenic dyslipidemia, hyperfibrinogenemia and platelet disfunction.

Sports form the metabolic response caused by the body’s adaptation to increased physical stress, which leads to the restructuring of metabolism for energy and plastic maintenance of sport activities. The restructuring of carbohydrate and lipid metabolism is caused primarily by the increasing energy request body, depending on type and intensity of sports activity. In this research blood serum lipids were studied depending on the orientation of the training process. A total of 108 athletes (men and women) aged 15 to 20 years of different sports qualification (I sports category, Candidate Master of Sports and Master of Sports) were examined, and a control group of 28 persons of the same age and gender. Depending of the direction of the training process there were isolated 3 groups: cyclical sport that develops mainly endurance (academic rowing); sports of complex nature (football, volleyball, handball and Nordic combined); and complex coordinated sports (artistic gymnastics). Were studied: total cholesterol, high density lipoproteins, low-density lipoproteins, atherogenic coefficient and triglycerides. The study was conducted in the preparatory period of the training cycle. The research had shown that the level of blood lipids depends on the orientation of training process and sports training. The most marked reduction of total cholesterol and high-density lipoproteins has been observed both in men and women in cyclic kinds of sports, developing mainly stamina that indicates that intense exercise in athletes who train primarily for endurance, cause the connection of lipids to the processes of energy supply of muscle activity.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

Dyslipidemia is a typical trait of patients with chronic kidney disease (CKD) and it is typically characterized by reduced high-density lipoprotein (HDL)-cholesterol(c) levels. The low HDL-c concentration is the only lipid alteration associated with the progression of renal disease in mild-to-moderate CKD patients. Plasma HDL levels are not only reduced but also characterized by alterations in composition and structure, which are responsible for the loss of atheroprotective functions, like the ability to promote cholesterol efflux from peripheral cells and antioxidant and anti-inflammatory proprieties. The interconnection between HDL and renal function is confirmed by the fact that genetic HDL defects can lead to kidney disease; in fact, mutations in apoA-I, apoE, apoL, and lecithin–cholesterol acyltransferase (LCAT) are associated with the development of renal damage. Genetic LCAT deficiency is the most emblematic case and represents a unique tool to evaluate the impact of alterations in the HDL system on the progression of renal disease. Lipid abnormalities detected in LCAT-deficient carriers mirror the ones observed in CKD patients, which indeed present an acquired LCAT deficiency. In this context, circulating LCAT levels predict CKD progression in individuals at early stages of renal dysfunction and in the general population. This review summarizes the main alterations of HDL in CKD, focusing on the latest update of acquired and genetic LCAT defects associated with the progression of renal disease.

Modest Effect

High density lipoproteins (HDL) are a highly heterogeneous population of particles composed of various lipids and proteins. They have been demonstrated to possess a diverse variety of functional properties which are thought to contribute to protection against cardiovascular disease (CVD). Proteomics studies have identified up to 75 different proteins which can associate with HDL. The basis for the compositional diversity of HDL is not known but a better understanding will yield important information about its broad functional diversity. To investigate the impact of common HDL apolipoproteins on the distribution of other apolipoproteins, we have begun to systematically fractionate plasma from various HDL apolipoprotein KO mice. Plasma from apoA-I, apoA-IV and apoA-II global KO mice was applied to gel filtration chromatography to distinguish HDL size populations. HDL particles sequestered by a phospholipid binding resin were proteomically analyzed by electrospray ionization mass spectrometry. By comparing elution volume shifts (i.e. particle size variations) for each HDL protein between WT controls and the KO models, we assessed the impact of the deleted protein on HDL size distributions. Ablation of apoA-I, while decreasing total HDL phospholipid by 70%, had a surprisingly small impact on the distribution of the majority of other HDL associated proteins - affecting only 9 of them. Genetic apoA-IV ablation had a similar modest effect shifting a distinct subset of 9 proteins. However, loss of apoA-II, in addition to causing a similar 70% reduction in overall HDL phospholipids, affected the size distribution of some 45 HDL proteins (including several complement proteins and paraoxonase-1). These data suggest that apoA-I, while associated with the majority of HDL phospholipid, may actually interact with relatively few of the lower abundance proteins known to be associated with HDL. ApoA-II on the other hand, may interact with many of these, perhaps acting as a docking site or adaptor molecule.

OBJECTIVE: The present study aimed to evaluate the effect of feeding diets enriched with fatty fish from the Amazon basin on lipid metabolism. METHODS: Male Wistar rats were divided into four groups: control group treated with commercial chow; Mapará group was fed diet enriched with Hypophthalmus edentatus; Matrinxã group was fed diet enriched with Brycon spp.; and, Tambaqui group was fed diet enriched with Colossoma macropomum. Rats with approximately 240g±0.60 of body weight were fed ad libitum for 30 days, and then were sacrificed for collection of whole blood and tissues. RESULTS: The groups treated with enriched diets showed a significant reduction in body mass and lipogenesis in the epididymal and retroperitoneal adipose tissues and carcass when compared with the control group. However, lipogenesis in the liver showed an increase in Matrinxã group compared with the others groups. The levels of serum triglycerides in the treated groups with Amazonian fish were significantly lower than those of the control group. Moreover, total cholesterol concentration only decreased in the group Matrinxã. High Density Lipoprotein cholesterol levels increased significantly in the Mapará and Tambaqui compared with control group and Matrinxã group. The insulin and leptin levels increased significantly in all treatment groups. CONCLUSION: This study demonstrated that diets enriched with fatty fish from the Amazon basin changed the lipid metabolism by reducing serum triglycerides and increasing high density lipoprotein-cholesterol in rats fed with diets enriched with Mapará, Matrinxã, and Tambaqui.

Abstract Type 2 Diabetes mellitus in obese persons is becoming threatening disease due to increasing prevalence of its microvascular and macro vascular complications. A multi targeted treatment can be considered better over single targeted treatment; in view of multiple pathways involved in pathogenesis of diabetes and its complications. This open labelled randomized controlled clinical Study was aimed to evaluate clinical efficacy of ‘Vidangadi Lauha’(An Ayurveda formulation) in comparison with metformin for obese type II diabetes mellitus. Participants were divided into two groups. Trial group received Vidangadi Lauha 5gm BID and control group received tablet metformin 500mg BID for duration of 3 months. Among 550 screened participants 120 participants were eligible, out of them 100 participants were enrolled and randomized by computer generated method, out of them 80 patients (40 in each group) completed the trial. Both the treatments were equally effective in reducing blood sugar fasting(F), post meal(PM) glycated Haemoglobin (HbA1C) and Body Mass Index (BMI). Vidangadi Lauha is more effective in reducing Ayurvedic Symptoms, waist hip ratio and cholesterol as compared to Metformin. High Density Lipoproteins (HDL) were improved by minor clinical difference in both the groups. Both the treatment does not have statistically significant effect in reducing Low Density Lipoproteins (LDL).

Abstract Background Blood glucose levels during pregnancy may reflect the severity of insulin secretory defects and/or insulin resistance during gestational diabetes mellitus (GDM) pregnancy. We hypothesized that suboptimal glycemic control in women with GDM could increase the risk of postpartum type 2 diabetes mellitus (T2DM) or prediabetes. Our objective was to evaluate the impact of plasma glucose levels throughout GDM pregnancy on the risk of postpartum T2DM or prediabetes. Methods The medical records of 706 women with GDM who underwent a postpartum 75-g, 2-hour oral glucose tolerance test at our institution between January 2011 and December 2018 were reviewed. These women were classified into 2 groups according to glycemic control during pregnancy: ≤ 1 occasion of either fasting glucose ≥ 95 mg/dL or 2-hour postprandial glucose ≥ 120 mg/dL was defined as optimal glycemic control or else was classified as suboptimal glycemic control. Rates of postpartum T2DM and prediabetes were compared between women with optimal (n = 505) and suboptimal (n = 201) glycemic control. Results The rates of postpartum T2DM and prediabetes were significantly higher in the suboptimal glycemic control group than in the optimal glycemic control group: 22.4% vs. 3.0%, P < 0.001 for T2DM and 45.3% vs. 23.5%, P < 0.001 for prediabetes. In a multivariate analysis, suboptimal glucose control during pregnancy was an independent risk factor for developing either postpartum T2DM or prediabetes. The adjusted odds ratios were 8.4 (95% confidence interval, 3.5–20.3) for T2DM and 3.9 (95% confidence interval, 2.5–6.1) for prediabetes. Conclusion Our findings suggest that blood glucose levels during GDM pregnancy have an impact on the risk of postpartum T2DM and prediabetes.

Diabetic bladder dysfunction (DBD), a prevalent complication of diabetes mellitus (DM), is characterized by a broad spectrum of symptoms including urinary urgency, frequency, and incontinence. As DBD is commonly diagnosed late, it is important to understand the chronic impact of DM on bladder tissues. While changes in bladder smooth muscle and innervation have been reported in diabetic patients, the impact of DM on the specialized epithelial lining of the urinary bladder, the urothelium (UT), is largely unknown. Quantitative polymerase chain reaction analysis and electron microscopy were used to evaluate UT gene expression and cell morphology 3, 9, and 20 wk following streptozotocin (STZ) induction of DM in female Sprague-Dawley rats compared with age-matched control tissue. Desquamation of superficial (umbrella) cells was noted at 9 wk DM, indicating a possible breach in barrier function. One causative factor may be metabolic burden due to chronic hyperglycemia, suggested by upregulation of the polyol pathway and glucose transport genes in DM UT. While superficial UT repopulation occurred by 20 wk DM, the phenotype was different, with significant upregulation of receptors associated with UT mechanosensation (transient receptor potential vanilloid subfamily member 1; TRPV1) and UT autocrine/paracrine signaling (acetylcholine receptors AChR-M2 and -M3, purinergic receptors P2X2 and P2X3). Compromised barrier function and alterations in UT mechanosensitivity and cell signaling could contribute to bladder instability, hyperactivity, and altered bladder sensation by modulating activity of afferent nerve endings, which appose the urothelium. Our results show that DM impacts urothelial homeostasis and may contribute to the underlying mechanisms of DBD.
