Impact of treatment modalities on quality of life and depression in type 2 diabetes.

Objective: Type 2 diabetes mellitus (T2DM) is a chronic disease with numerous complications that increase mortality and reduce the quality of life (QoL). The current study compares QoL in T2DM patients treated with insulin to those treated with oral antihyperglycemics (OAHs), as well as the frequency and severity of depression in patients.

Subjects And Methods: This prospective cross-sectional study included 200 patients with insulin or OAHs.

The Na/K-ATPase: A potential therapeutic target in cardiometabolic diseases.

Cardiometabolic diseases (CMD) are a direct consequence of modern living and contribute to the development of multisystem diseases such as cardiovascular diseases and diabetes mellitus (DM). CMD has reached epidemic proportions worldwide. A sodium pump (Na/K-ATPase) is found in most eukaryotic cells' membrane and controls many essential cellular functions directly or indirectly.

Redox and biometal status in Wistar rats after subacute exposure to fluoride and selenium counter-effects.

This study aimed to investigate the effect of 150 mg/L sodium fluoride (NaF) on redox status parameters and essential metals [copper (Cu), iron (Fe), and zinc (Zn)] in the blood, liver, kidney, brain, and spleen of Wistar rats and to determine the protective potential of selenium (Se) against fluoride (F) toxicity. Male Wistar rats were randomly distributed in groups of five (n=5) receiving tap water (control) or water with NaF 150 mg/L, NaF 150 mg/L + Se 1.5 mg/L, and Se 1.

Hypothyroidism and Risk of Cardiovascular Disease.

Thyroid hormones (TH) have a significant impact on cellular oxidative metabolism. Besides that, they maintain vascular homeostasis by positive effects on endothelial and vascular smooth muscle cells. Subclinical (SCH) and clinical (CH) hypothyroidism influences target organs by changing their morphology and function and impaired blood and oxygen supply induced by accelerated atherosclerosis.

Follicular and serum levels of vitamin D in women with unexplained infertility and their relationship with fertilization outcome: an observational pilot study.

Introduction: Follicular and serum vitamin D are considered potential markers of the oocyte and embryos' quality and predictors of fertilization (IVF) outcomes.

Methods: This retrospective cross-sectional study correlated vitamin D in sera and follicular fluid of women with unexplained infertility mutually and with IVF outcomes. ELISA was used for measuring vitamin D.

Leptin and Obesity: Role and Clinical Implication.

The peptide hormone leptin regulates food intake, body mass, and reproductive function and plays a role in fetal growth, proinflammatory immune responses, angiogenesis and lipolysis. Leptin is a product of the obese () gene and, following synthesis and secretion from fat cells in white adipose tissue, binds to and activates its cognate receptor, the leptin receptor (LEP-R). LEP-R distribution facilitates leptin's pleiotropic effects, playing a crucial role in regulating body mass a negative feedback mechanism between adipose tissue and the hypothalamus.

Effects of Metformin-Single Therapy on the Level of Inflammatory Markers in Serum of Non-Obese T2DM Patients with NAFLD.

Hyperbaric Oxygen Therapy and Vascular Complications in Diabetes Mellitus.

Vascular complications in patients with diabetes mellitus (DM) are common. Since impaired oxygen balance in plasma plays an important role in the pathogenesis of chronic DM-associated complications, the administration of hyperbaric oxygen therapy (HBOT) has been recommended to influence development of vascular complications. Hyperbaric oxygen therapy involves inhalation of 100% oxygen under elevated pressure from 1.

Effects of Root on Vascular Diseases.

Background: Gentiana lutea (GL), commonly known as yellow gentian, bitter root, and bitterwort, belongs to family Gentianaceae. GL belongs to genus Gentiana, which is a rich natural source of iridoids, secoiridoids, xantones, flavonoids, triterpenoids, and carbohydrates. Medicinal plants from Gentiana species have anti-oxidant, anti-inflammatory, anti-mitogenic, anti-proliferative, and lipidlowering effects, as well as a cardioprotective, hypotensive, vasodilator and anti-platelet activities.

Regulation of nitric oxide production in hypothyroidism.

Hypothyroidism is a common endocrine disorder that predominantly occurs in females. It is associated with an increased risk of cardiovascular diseases (CVD), but the molecular mechanism is not known. Disturbance in lipid metabolism, the regulation of oxidative stress, and inflammation characterize the progression of subclinical hypothyroidism.

Redox control of vascular biology.

Redox control is lost when the antioxidant defense system cannot remove abnormally high concentrations of signaling molecules, such as reactive oxygen species (ROS). Chronically elevated levels of ROS cause oxidative stress that may eventually lead to cancer and cardiovascular and neurodegenerative diseases. In this review, we focus on redox effects in the vascular system.

Serum nitric oxide levels correlate with quality of life questionnaires scores of hypothyroid females.

Primary hypothyroidism can affect lipid metabolism, cardiovascular (CV) function, and overall patients' quality of life (QoL). Decrease in serum nitric oxide (NO) levels could promote the atherosclerosis acceleration in hypothyroid patients. Our hypothesis is that serum NO level is altered in hypothyroidism; more specifically, we hypothesize that the early vascular changes that can be observed in hypothyroidism could be due to these alterations and that serum NO levels are associated with lipid levels in female patients diagnosed with subclinical hypothyroidism (SCH) or clinical hypothyroidism (CH).

Effect of Hyperbaric Oxygen Therapy on Fatty Acid Composition and Insulin-like Growth Factor Binding Protein 1 in Adult Type 1 Diabetes Mellitus Patients: A Pilot Study.

Objective: Metabolic changes in type 1 diabetes mellitus (T1DM) impair vasodilation, and this leads to tissue hypoxia and microvascular pathology. Hyperbaric oxygen therapy (HBOT) can significantly improve the outcome of ischemic conditions in T1DM patients and reduce vascular complications. The aim of our study was to assess the effects of HBOT on plasma fatty acid (FA) composition, and expression of insulin-like growth factor binding protein 1 (IGFBP-1) in T1DM patients.

Drug Delivery Systems for Diabetes Treatment.

Background: Insulin is essential for the treatment of Type 1 diabetes mellitus (T1DM) and is necessary in numerous cases of Type 2 diabetes mellitus (T2DM). Prolonged administration of anti-diabetic therapy is necessary for the maintenance of the normal glucose levels and thereby preventing vascular complications. A better understanding of the disease per se and the technological progress contribute to the development of new approaches with the aim to achieve better glycemic control.

Early Effects of Hyperbaric Oxygen on Inducible Nitric Oxide Synthase Activity/Expression in Lymphocytes of Type 1 Diabetes Patients: A Prospective Pilot Study.

This study aimed at examining the early effects of hyperbaric oxygen therapy (HBOT) on inducible nitric oxide synthase (iNOS) activity/expression in lymphocytes of type 1 diabetes mellitus (T1DM) patients. A group of 19 patients (mean age: 63 ± 2.1) with T1DM and with the peripheral arterial disease were included in this study.

Hypothesis regarding the effects of gonadotropins on the level of free fatty acids and phospholipids in serum and follicular fluid during controlled ovarian stimulation.

Controlled ovarian stimulation (COS) is used to augment the number of retrieved oocytes in in vitro fertilization (IVF). Follicular fluid (FF) contributes significantly to oocyte quality. Since the FF is composed of follicular secretions and plasma exudation, it reflects alterations in granulosa and thecal cells secretion as well as changes in the level of plasma constituents.

17β-estradiol inhibits hepatic iNOS via the activation of the estrogen receptor ER-α and inhibition of erk1/2-mir-221 axis.

17β-Estradiol (E2) is known to negatively regulate inducible nitric oxide (NO) synthase (iNOS) expression via estrogen receptor alpha (ER-α) activation in aortic vascular smooth muscle cells.Therefore, we sought to determine whether E2 can inhibit iNOS in hepatic tissue via the activation of ER-α and whether extracellular signal-regulated kinases 1/2 (ERK1/2)-miR-221 axis is involved in this process. Male Wistar rats were treated with a bolus injection of E2 intraperitoneally (40 μg/kg), and 24 hours after treatment the animals were sacrificed and the livers excised.

Genetic Markers for Coronary Artery Disease.

Coronary artery disease (CAD) and myocardial infarction (MI) are recognized as leading causes of mortality in developed countries. Although typically associated with behavioral risk factors, such as smoking, sedentary lifestyle, and poor dietary habits, such vascular phenotypes have also long been recognized as being related to genetic background. We review the currently available data concerning genetic markers for CAD in English and non-English articles with English abstracts published between 2003 and 2018.

Estradiol-mediated regulation of hepatic iNOS in obese rats: Impact of Src, ERK1/2, AMPKα, and miR-221.

This study aimed to investigate in vivo effects of estradiol on the regulation of hepatic inducible nitric oxide synthase (iNOS) expression in the high fat (HF) diet-induced obesity. Also, we aimed to investigate whether activation of the extracellular signal-regulated kinase (ERK1/2), adenosine monophosphate-activated protein kinase (AMPK), Src kinase, and miR-221 is involved in estradiol-mediated regulation of iNOS in the liver of obese male Wistar rats. Male Wistar rats were fed a standard laboratory diet or a HF diet for 10 weeks.

Involvement of PI3K, Akt and RhoA in Oestradiol Regulation of Cardiac iNOS Expression.

Background: Oestradiol is an important regulatory factor with several positive effects on the cardiovascular (CV) system. We evaluated the molecular mechanism of the in vivo effects of oestradiol on the regulation of cardiac inducible nitric oxide (NO) synthase (iNOS) expression and activity.

Methods: Male Wistar rats were treated with oestradiol (40 mg/kg, intraperitoneally) and after 24 h the animals were sacrificed.

PCSK9 and Hypercholesterolemia: Therapeutic Approach.

Despite the intensive research and progress in modern pharmacotherapy, hypercholesterolemia and related cardiovascular complications remain one of the leading causes of mortality and disability in the modern world. A significant contribution to the treatment of hypercholesterolemia was made by the discovery of proprotein convertase subtilisin/kexin type 9 (PCSK9). This enzyme is responsible for the degradation of the low-density lipoprotein (LDL) receptor (LDLR) found at the surface of the plasma membrane in the liver and directly associated with serum LDL level.

Regulation of Na+/K+-ATPase by Estradiol and IGF-1 in Cardio-Metabolic Diseases.

Background: The sodium/potassium- adenosine- triphosphatase (Na+/K+-ATPase) is an important mediator in vasculature tone and contractility, and its abnormal regulation has been implicated in many diseases such as obesity, insulin resistance, diabetes, and hypertension. Decreased Na+/K+-ATPase abundance and its altered isoform expression induce cardiomyocytes death and cardiac dysfunction, possibly leading to the development of myocardial dilation and heart failure. Therefore, the regulation of Na+/K+-ATPase activity/expression could be important in treatment and possible prevention of cardio-metabolic diseases.

17β-Estradiol protects against the effects of a high fat diet on cardiac glucose, lipid and nitric oxide metabolism in rats.

The aim of this study was to investigate the in vivo effects of 17β-estradiol (E) on myocardial metabolism and inducible nitric oxide synthase (iNOS) expression/activity in obese rats. Male Wistar rats were fed with a normal or a high fat (HF) diet (42% fat) for 10 weeks. Half of the HF fed rats were treated with a single dose of E while the other half were placebo-treated.

Hormonal Regulation of Nitric Oxide (NO) in Cardio-metabolic Diseases.

Background: Nitric oxide (NO) is a potential biochemical, cardio-metabolic risk marker. The production of NO is catalyzed by different isoforms of enzymes, NO synthases (NOS). An altered NO level is associated with obesity, insulin resistance (IR), diabetes and cardiovascular diseases (CVD).
