Metabolic syndrome in association with novel dietary index, metabolic parameters, nesfatin-1 and omentin-1

BackgroundMetabolic syndrome is a prevalent and common health problem and numerous studies have revealed the role of diet and lifestyle change in prevention of metabolic syndrome. However, the novel dietary index, cardioprotective index (CPI) and its association with metabolic syndrome is not investigated yet. In the current study, we evaluated the association between metabolic syndrome and its components, CPI, Nesfatin-1 and Omentin-1in a cross-sectional study.MethodsThree hundred forty eight overweight and obese individuals with metabolic syndrome were recruited. Subjects underwent anthropometric and laboratory assays including metabolic markers, Nesfatin-1 and Omentin-1 with commercial kits.ResultsThose at the first tertile of CPI had lower high density lipoprotein concentrations (HDL) and higher low density lipoprotein concentrations (LDL), triglyceride (TG), systolic and diastolic blood pressures (SBP, DBP) levels compared with those at the highest tertiles (P < 0.05). After adjustment for the confounding effects of age, sex, body mass index, physical activity and total calorie intake, LDL lost its significance across CPI tertiles. Moreover, serum total cholesterol, insulin and insulin resistance were not significant across CPI tertiles neither in crude nor in adjusted models (P > 0.05). Additionally, being at the third tertile of CPI was accompanied with significantly higher Nesfatin-1 and Omentin-1 levels compared with lowest tertiels (P < 0.05) in crude and confounder – adjusted models. Conclusions: To our findings, CPI was in positive relationship with metabolic parameters, blood pressure, Nesfatin-1 and Omentin-1 levels in metabolic syndrome. Further future studies will help to elaborate the causality.Clinical trial numberNot applicable.

Antidepressant and anxiolytic effects of Wuling Capsule in CSDS mice: Alleviating HPA axis hyperactivity via the Nesfatin-1/NF-κB signaling pathway

Ethnopharmacological relevanceWuling capsule, composed of the traditional Chinese medicine Wuling mycelia powder, is made by fermenting and processing Xylaria nigripes (Kl.) Sacc. Clinically, it is commonly used to alleviate depression and anxiety. However, the mechanisms through which Wuling capsule exerts its therapeutic benefits have not been clearly defined. Aim of the studyThis study aims to elucidate the mechanisms by which Wuling capsule alleviates depression and anxiety like behaviors induced by chronic social defeat stress (CSDS) in mice. Materials and methodsHigh-performance liquid chromatography-tandem mass spectrometry system was used to identify the components of the Wuling capsule. Mice were subjected to CSDS to induce depression and anxiety-like behaviors. The expression of hypothalamic corticotropin-releasing hormone (CRH) and Nesfatin-1, as well as serum levels of adrenocorticotropic hormone (ACTH) and corticosterone (CORT) were quantified. Behavioral assessments included the open field test, elevated plus maze, sucrose preference test, and forced swim test to evaluate depression and anxiety levels. Specific manipulation of Nesfatin-1 in the paraventricular nucleus of the hypothalamus (PVN) or cells was achieved through stereotaxic virus injection or plasmid transfection. Intracerebral cannula implantation was used for PVN-specific drug administration. ResultsA total of 123 different components were identified in Wuling capsule. CSDS induced depression and anxiety-like behaviors in mice, along with hyperactivation of the HPA axis, increased hypothalamic Nesfatin-1 levels, and elevated nuclear factor kappa-B (NF-κB) phosphorylation. Overexpression of Nesfatin-1 in the hypothalamus mimicked the effects of CSDS. Conversely, knockdown of hypothalamic Nesfatin-1 or PVN-specific administration of Nesfatin-1 antibody or NF-κB antagonist mitigated CSDS-induced depression and anxiety-like behaviors and hypothalamic-pituitary-adrenal (HPA) axis hyperactivity. In neuroblastoma-2a (N2a) cells, overexpression of Nesfatin-1 led to increased NF-κB phosphorylation and CRH levels, whereas knockdown of Nesfatin-1 produced the opposite effects. Treatment with Wuling capsule alleviated CSDS-induced depression and anxiety-like behaviors, HPA axis hyperactivity, and activation of the hypothalamic Nesfatin-1/NF-κB pathway. ConclusionsThe hypothalamic Nesfatin-1/NF-κB pathway plays a significant role in depression by modulating the HPA axis and is involved in the antidepressant and anxiolytic effects of Wuling capsule.

Uncovering nesfatin-1 and irisin hormones in schizophrenia and psychosis patients: A comparative investigation

ObjectiveThis study aims to elucidate the potential roles of the hormones nesfatin-1 and irisin in the pathophysiology of schizophrenia and psychosis. MethodsThe study involved 80 participants, divided into three groups: schizophrenia (n=30), psychosis (n=20), and controls (n=30). Blood samples were collected from these participants, and the levels of irisin and nesfatin-1 were measured using the ELISA method. ResultsThe findings revealed that nesfatin-1 levels in schizophrenia patients were significantly higher compared to those in psychosis patients and controls. Additionally, nesfatin-1 levels in psychosis patients were significantly higher than in controls. In contrast, irisin levels were significantly lower in schizophrenia patients compared to both psychosis patients and controls. DiscussionThese results suggest that nesfatin-1 and irisin may have important implications for understanding and treating schizophrenia and psychosis. Further research is needed to explore the roles of these hormones in the etiology, diagnosis, and treatment of these conditions.

The role of nesfatin-1 in kidney diseases.

Nesfatin-1 is a recently discovered protein with a pleiotropic function on various organs, including kidneys. This molecule presents antiapoptotic, antihyperglycemic, antioxidative, and anorectic features. Available data regarding the role of nesfatin-1 in kidney function and diseases focuses on chronic kidney disease, acute kidney injury, blood pressure, and renal cell carcinoma. Various studies have shown that the levels of nesfatin-1 were increased in patients with diabetic kidney disease (DKD); therefore, it was suggested that nesfatin-1 might act as an early DKD marker. Furthermore, the potential protective function of nesfatin-1 against inflammation, oxidative stress, fibrosis, and apoptosis in kidney tissues was described in several studies. Alternatively, as reported in the literature, a positive correlation between blood pressure elevation and nesfatin-1 levels was noted. Moreover, nesfatin-1 might exert influence on renal cell carcinoma progression and invasion of cancerous cells. Nesfatin-1 shows considerable potential for acting as a prognostic marker or a defensive factor for kidney diseases; however, further investigation, especially in the pediatric population, is still required.

Evaluation of the Effects of Naringenin on the Hypothalamic mRNA Levels of nesfatin-1 and CRH in a Rat Model of PCOS

Background: Polycystic ovary syndrome (PCOS) is a common endocrine disorder and a leading cause of infertility in women. Studies suggest that naringenin may improve ovarian function; however, its molecular mechanism within the hypothalamus-pituitary-gonad (HPG) axis remains unclear. Objectives: This study investigated the role of naringenin on the expression of corticotropin-releasing hormone (CRH) and nesfatin-1 genes in the hypothalamus of PCOS rats. Methods: Twenty rats, each weighing 180 - 200 g, were divided into four groups (n = 5). Polycystic ovary syndrome was induced by administering estradiol valerate (2 mg per rat). The control and PCOS groups received saline, while the other two PCOS groups received intraperitoneal injections of naringenin at doses of 20 and 50 mg/kg for 14 days. Hypothalamic samples were collected to measure gene expression via real-time PCR. Results: The PCOS group showed a significant decrease in CRH and nesfatin-1 gene expression compared to the control group (P ≤ 0.05). Naringenin treatment significantly increased the expression of CRH and nesfatin-1 genes in comparison to the PCOS group (P ≤ 0.05). Conclusions: Naringenin appears to have therapeutic potential in improving ovarian function in PCOS. Its effects are mediated through up-regulation of hypothalamic neuropeptides upstream of GnRH neurons.

Comparison of Serum Nesfatin-1 and Visfatin Levels Between Patients with Rheumatoid Arthritis and Healthy Controls

Even though elevated nesfatin-1 levels were reported in patients with rheumatoid arthritis (RA) previously, the possible role of body mass index (BMI) was not excluded. The aim of the present study was to compare serum nesfatin-1 and visfatin levels between patients with RA and healthy controls who have normal BMI values (18.50.05). It seems that nesfatin-1 levels are significantly higher in RA patients compared to healthy peers. However, nesfatin-1 levels were not found related to disease activity.

Nesfatin-1 enhances vascular smooth muscle calcification through facilitating BMP-2 osteogenic signaling

Vascular calcification (VC) arises from the accumulation of calcium salts in the intimal or tunica media layer of the aorta, contributing to higher risk of cardiovascular events and mortality. Despite this, the mechanisms driving VC remain incompletely understood. We previously described that nesfatin-1 functioned as a switch for vascular smooth muscle cells (VSMCs) plasticity in hypertension and neointimal hyperplasia. In this study, we sought to investigate the role and mechanism of nesfatin-1 in VC. The expression of nesfatin-1 was measured in calcified VSMCs and aortas, as well as in patients. Loss- and gain-of-function experiments were evaluated the roles of nesfatin-1 in VC pathogenesis. The transcription activation of nesfatin-1 was detected using a mass spectrometry. We found higher levels of nesfatin-1 in both calcified VSMCs and aortas, as well as in patients with coronary calcification. Loss-of-function and gain-of-function experiments revealed that nesfatin-1 was a key regulator of VC by facilitating the osteogenic transformation of VSMCs. Mechanistically, nesfatin-1 promoted the de-ubiquitination and stability of BMP-2 via inhibiting the E3 ligase SYTL4, and the interaction of nesfatin-1 with BMP-2 potentiated BMP-2 signaling and induced phosphorylation of Smad, followed by HDAC4 phosphorylation and nuclear exclusion. The dissociation of HDAC4 from RUNX2 elicited RUNX2 acetylation and subsequent nuclear translocation, leading to the transcription upregulation of OPN, a critical player in VC. From a small library of natural compounds, we identified that Curculigoside and Chebulagic acid reduced VC development via binding to and inhibiting nesfatin-1. Eventually, we designed a mass spectrometry-based DNA-protein interaction screening to identify that STAT3 mediated the transcription activation of nesfatin-1 in the context of VC. Overall, our study demonstrates that nesfatin-1 enhances BMP-2 signaling by inhibiting the E3 ligase SYTL4, thereby stabilizing BMP-2 and facilitating the downstream phosphorylation of SMAD1/5/9 and HDAC4. This signaling cascade leads to RUNX2 activation and the transcriptional upregulation of MSX2, driving VC. These insights position nesfatin-1 as a potential therapeutic target for preventing or treating VC, advancing our understanding of the molecular mechanisms underlying this critical cardiovascular condition.

Investigation of the Relationship between Plasma Nesfatin-1 Levels and Neutering in Dogs.

Neutering of dogs, whether male or female, provides various benefits such as contraception, population control, and the prevention of reproductive disorders and undesirable sexual behaviors. However, it is also associated with an increased risk of obesity, which may be directly linked to post-neutering hormonal changes. Our study aims to determine the effects of neutering on plasma levels of nesfatin-1, serotonin, dopamine, TSH, and T4-hormones implicated in obesity and metabolic regulation. Fourteen dogs (seven males and seven females), aged between 1 and 3 years, were included in this study. Male dogs underwent orchiectomy and females underwent ovariohysterectomy. Blood samples were collected before surgery and on days 7 and 14 post-operatively to measure the plasma levels of these hormones using ELISA. The results showed a significant decrease in nesfatin-1, serotonin, and T4 levels, along with a significant increase in TSH levels in both male and female dogs post-neutering. While these hormonal changes are likely part of the body's adaptive response to neutering, they may represent a potential mechanism that contributes to the long-term tendency toward obesity in neutered dogs.

Evaluating the impact of metabolic and cognitive stress on ghrelin and nesfatin-1 hormones in patients with diabetes and diabetic depression.

Nesfatin-1 and ghrelin, initially recognised as hormones involved in regulating energy, have emerged as crucial players with vital functions in various human body systems. In this study, we conducted a comparative assessment of nesfatin-1 and ghrelin responses in individuals experiencing metabolic stress due to diabetes, those with depressive diabetes characterised by both metabolic and mental stress, and healthy controls. We collected blood samples from a total of 90 participants, consisting of 30 people with type II diabetes mellitus (DM), 30 people with type II DM and major depressive disorders, and 30 healthy individuals. Diabetes was diagnosed based on glycated haemoglobin (HbA1c) levels, while depression was assessed using DSM-V criteria. Insulin resistance (HOMA-IR) was calculated, and serum ghrelin and nesfatin-1 levels were measured using ELISA kits. We observed statistically significant decreases in nesfatin-1 and ghrelin levels in the diabetic group (p<0.0001). However, in the depressive diabetic group, nesfatin-1 levels increased significantly, while ghrelin levels decreased further. The nesfatin-1 to ghrelin ratio decreased in the diabetic group but increased significantly in the depressive diabetic group (p<0.0001). Nesfatin-1 and ghrelin hormones exhibit parallel impacts in response to metabolic stress, but nesfatin-1 demonstrates contrasting actions compared to ghrelin when mental stress is added to metabolic stress. The findings of this study suggest that nesfatin-1 and ghrelin hormones may play active roles as protective, prognostic, and even etiological factors in various stress situations, particularly those involving mental stress, in addition to their known functions in regulating energy.

Relationship of Serum Nesfatin-1 and Insulin-Like Growth Factor-1 Levels with Adverse Pregnancy Outcomes in Patients with Polycystic Ovary Syndrome.

To investigate the relationship between serum nesfatin-1 and insulin-like growth factor-1 (IGF-1) levels and adverse pregnancy outcomes (APOs) in patients with polycystic ovary syndrome (PCOS). Observational study. Place and Duration of the Study: The study was performed from June 2021 to 2023 in the General Gynaecology section at the Maternity & Child Care Center of Qinhuangdao, Hebei, China. A total of 120 pregnant women with PCOS were divided into the control and study groups. The control group consisted of 70 pregnant women who successfully delivered healthy newborns, whereas the study group included 50 pregnant women who experienced APOs. The serum nesfatin-1 and IGF-1 levels in both groups were measured upon admission. The potential influencing factors of APOs in pregnant women with PCOS and the predictive value of serum nesfatin-1 and IGF-1 for APOs were analysed. Serum nesfatin-1 and IGF-1 levels were significantly higher in the study group than in the control group (p <0.05). Multivariate analysis revealed that testosterone ≥45μg/L, body mass index ≥25kg/m², waist-hip ratio ≥0.80, gestational diabetes mellitus, nesfatin-1, and IGF-1 were independent risk factors of APOs in patients with PCOS. The AUC for IGF-1 plus nesfatin-1 in predicting APOs in pregnant women with PCOS was 0.900 (95% CI: 0.845, 0.955). Elevated serum nesfatin-1 and IGF-1 levels are associated with pregnancy outcomes of patients with PCOS.

Investigation of the Effectiveness of Nutrition at the Molecular Level in Patients with Sepsis

Objective: The aim of this study was to compare inflammatory and anti-inflammatory molecule levels in sepsis patients receiving normal (1.3 mg/kg/day) and high (2 mg/kg/day) protein supplementation. Methods: Two groups of patients were compared based on protein supplementation: normal (1.3 mg/kg/day) and high (2 mg/kg/day). Levels of kallistatin, nesfatin-1, plasminogen activator inhibitor-1 (PAI-1), and high mobility group box-1 (HMGB-1) were measured. Disease severity was assessed using APACHE II, SAPS, and SOFA scores. Results: Demographic characteristics and intensive care scores were similar between groups (p&gt;0.05). Group 1 had significantly higher 0-hour levels of HMGB-1, kallistatin, PAI-1, and nesfatin-1 compared to 24 and 48 hours (p&lt;0.001). Group 2 had higher 0-hour levels, but changes were not significant (p&gt;0.05) Conclusions: High-dose protein feeding in sepsis patients may not suppress inflammation-related protein synthesis despite the presence of oxidative damage and muscle catabolism.

Electroacupuncture negatively regulates the Nesfatin-1/ERK/CREB pathway to alleviate HPA axis hyperactivity and anxiety-like behaviors caused by surgical trauma

BackgroundHyperactivity of the hypothalamic–pituitary–adrenal (HPA) axis constitutes a pivotal response by surgical trauma, manifesting as a critical aspect of the acute stress reaction. This hyperactivity resulted in adverse surgical outcomes and is often associated with increased postoperative anxiety. Increased evidence suggests that Nesfatin-1 plays a crucial role in stress responses and stress-related psychiatric disorders. Electroacupuncture (EA) is widely used to alleviate stress responses and anxiety, although its mechanism of action remains unclear. This study aimed to assess the mechanisms by which hypothalamic Nesfatin-1 contribute to the alleviation of HPA axis hyperactivity and anxiety by EA.MethodsPartial hepatectomy (HT) was performed to simulate surgical trauma, and EA was applied at Zusanli (ST36) and Sanyinjiao (SP6). The levels of hypothalamic Nesfatin-1, c-Fos, and corticotropin-releasing hormone (CRH) were detected, and serum adrenocorticotropic hormone (ACTH) and corticosterone (CORT) were regarded as indicators of HPA axis activity. Anxiety levels were assessed through open field tests (OFT), elevated plus maze (EPM), and light–dark box tests (LDBT). To investigate the role of Nesfatin-1, its expression was modulated using stereotactic viral injections or plasmid transfections. Transcriptome sequencing was employed to explore the downstream signaling pathways of Nesfatin-1. Additionally, brain cannula implantation was performed to facilitate targeted drug administration.ResultsOur findings demonstrated that EA reduced the hypothalamic overexpression of CRH and Nesfatin-1, as well as serum levels of ACTH and CORT. Additionally, it alleviated anxiety-like behaviors resulting from surgical trauma. We observed that overexpression of Nesfatin-1 in the hypothalamic paraventricular nucleus (PVN) triggered hyperactivity of the HPA axis and anxiety. Conversely, knocking down Nesfatin-1 in the PVN reversed these effects caused by surgical trauma. Transcriptome sequencing identified the extracellular regulated protein kinases (ERK)/cAMP-response element binding protein (CREB) pathway as a key mediator in the impacts of surgical trauma and EA on the hypothalamus. Both in vivo and in vitro studies showed that overexpression of Nesfatin-1 activated the ERK/CREB pathway. Furthermore, administering ERK or CREB inhibitors into the PVN mitigated HPA axis hyperactivity and anxiety-like behaviors induced by surgical trauma. Finally, EA was observed to decrease the phosphorylation levels of ERK and CREB in the PVN.ConclusionEA alleviates HPA axis hyperactivity and anxiety-like behaviors caused by surgical trauma through inhibition of Nesfatin-1/ERK/CREB pathway in the hypothalamus.

Estimation of NESFATIN-1 and VEGFA Levels in Iraqi Celiac Disease Patients Infected with Helicobacter pylori

Celiac disease is an autoimmune disease. It is associated with atrophy of the intestinal villi, leading to reduced absorbed nutrients. Nesfatin-1 is a peptide that is used as a laboratory detection tool in CD detection. VEGF plays a role in the permeability of endothelial functions. Helicobacter pylori are colonized and cause stomach injury in adults and children. H. pylori are cause chronic gastritis, duodenal ulcers, and adenocarcinomas. The study was estimated the NESFATIN-1 and VEGFA in CD with H. pylori. (41) CD with H. pylori and (31) CD without H. pylori, (42) control group is included in the study. Nesfatin-1 and VEGFA were measured in the entire participant. Nesfatin-1 was higher in CD than in the control group. It was lower in men than women and lowered in persons under 35 years of age than in persons over 35 years of age. VEGF was higher in patients with CD, it was higher in men than in women, and higher in persons less than 35 years of age than in persons with more than 35 years of age; also, it was higher in less than 35 years of age than in more than 35 years of age, a high level of VEGFA was detected in CD. VEGF expression change is reported in some tumors; it is unsuitable for detecting celiac disease but can be used for patients' follow-ups. CD cases have higher nesfatin-1 levels than in IBS-D or the control group. Deficiencies of minerals and vitamins are detected in CD patients irrespective of age and gender. All CD cases had nutritional deficiencies.

Dynamics of Serum Inflammatory Markers and Adipokines in Patients: Implications for Monitoring Abnormal Body Weight: Preliminary Research.

This study aimed to investigate the influence of abnormal body weight on inflammatory markers and adipokine levels across varied body mass index (BMI) categories. The cohort included 46 participants categorized into normal BMI (group I; n = 19), overweight (group II; n = 14), and obesity (group III; n = 13). Inflammatory markers (hsCRP and IL-6) and adipokines (Adiponectin, Leptin, Nesfatin-1, and Zinc-α2-glycoprotein) were assessed to discern effective indicators of inflammation in individuals with abnormal body weight. Additionally, the full lipid profile was also assessed (total cholesterol, triglycerides, LDL-C, HDL-C). The results indicated significant biochemical changes, particularly in IL-6 and Leptin levels, in participants with a BMI over 25. The levels of ZAG protein were negatively correlated with the HDL-C and LDC-L levels with statistical significance (Pearson: -0.57, p = 0.001, and Pearson: -0.41, p = 0.029, for HDL-C and LDL-C, respectively), suggesting that the level of ZAG is also inversely proportional to the amount of cholesterol. Statistical analyses revealed decreased Zinc-α2-glycoprotein (ZAG) levels and increased Adiponectin, Leptin, and IL-6 levels in individuals with abnormal body weight. Correlation analyses demonstrated a statistically significant upward trend for IL-6 (p = 0.0008) and Leptin (p = 0.00001), with a similar trend observed for hsCRP without statistical significance (p = 0.113). IL-6 levels in the overweight group were 158.71% higher than in the normal-weight group, while the obese group exhibited a 229.55% increase compared to the normal-weight group. No notable changes have been recorded for the levels of Nesfatin-1. Based on our results, we propose IL-6, Leptin, and ZAG as potential biomarkers for monitoring interventions and assessing patient conditions in those with abnormal BMIs. Further research with a larger patient cohort is warranted to validate these correlations in overweight and obese individuals.

Effect of cinnamaldehyde on nesfatin-1 levels in diabetic rats

Purpose: To evaluate the effect of cinnamaldehyde (CA) on fasting blood glucose (FBG), body weight, lipid profile, and nesfatin-1 levels in healthy and diabetic (DM) rats. &#x0D; Methods: Ten groups with eight rats per group were used. Healthy and diabetic sham groups were administered 1 mL of saline for 28 days by intragastric gavage. Healthy and diabetic control groups were administered 1 mL 0.5 % dimethyl sulfoxide (DMSO) for 28 days by intragastric gavage. Other diabetic and healthy groups (HG) received 10, 20, and 40 mg/kg CA for 28 days by intragastric gavage, once daily. Diabetes was induced with streptozotocin (50 mg/kg intraperitoneally). Rats were defined as diabetic when FBG was &gt; 250 mg/dL. Enzyme-linked immunosorbent assay (ELISA) was used to assess serum nesfatin-1 concentrations. Fasting blood glucose (FBG) values were evaluated with a glucometer. &#x0D; Results: Day 28 weights of all DM and HG + 40 mg/kg CA groups were lower than day 1 weights (p &lt; 0.05). Triglyceride values of DM + 40 mg/kg CA group were lower than DM sham and control group (p ≤ 0.001). Low-density lipoprotein (LDL) and cholesterol levels of the CA-administered healthy groups were higher than healthy control groups (p ≤ 0.001). Nesfatin-1 levels of all DM groups were lower than all healthy groups, and nesfatin-1 levels of all CA-administered healthy and DM groups were lower than healthy and DM sham and control groups, but these were not significant (p &gt; 0.001). &#x0D; Conclusion: Although not significant, the decrease in nesfatin-1 level is evidence that CA has an anti-obesity effect in both healthy and diabetic rats. In contrast to its antihyperlipidemic effect in diabetic conditions, CA has hyperlipidemic effect in healthy conditions.

Leptin, Nesfatin-1, Orexin-A, and Total Ghrelin Levels in Drug-Naive Panic Disorder.

This study aimed to examine the changes in serum nesfatin-1, leptin, orexin-A, and total ghrelin levels of patients diagnosed with drug-naive panic disorder (PD) before and after six weeks of the treatment and to compare the findings with the healthy subjects. The neuropeptides were measured in venous blood samples taken from 32 patients and 32 healthy subjects. The blood samples of the patients who used paroxetine 20 mg/day plus alprazolam 0.5 mg/day were retaken again after six weeks. Measurements were performed with the Enzyme-Linked Immunosorbent Assay (ELISA) method. Serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were found to be significantly lower than the control group (p<0.001, p<0.001, p<0.001, and p<0.001, respectively). When the serum nesfatin-1, leptin, orexin-A and total ghrelin levels of the patient group were compared before and after treatment, significant differences were found in terms of orexin-A and total ghrelin levels (p=0.046, p<0.001, respectively). However, no significant differences were found in terms of nesfatin-1and leptin levels (p=0.205, p=0.988, respectively). This study reports that PD, like other anxiety disorders, may affect serum nesfatin-1, leptin, orexin-A, and total ghrelin levels, and there may be a relationship between PD treatment and the levels of these neuropeptides. The variability of this relationship among the neuropeptides examined indicates that various factors other than treatment play a role in this process.

The Relation between Plasma Nesfatin-1 Levels and Aggressive Behavior in Pit Bull Dogs.

Aggression is a prevalent and concerning behavioral issue in dogs. Pit Bull dogs, known for their high levels of aggression, are recognized as a focus of concern in society. In our study, we aimed to investigate the behavioral characteristics of Pit Bull dogs and explore the potential roles of peptides involved in the neurobiology of aggression. Initially, female, and male dogs underwent aggression tests, and their aggression levels were categorized. Plasma nesfatin-1, serotonin, oxytocin, and dopamine levels were quantified using ELISA, with blood samples collected after a 24 h fasting period and 2 h post-refeeding. Our findings indicate that aggression in Pit Bull dogs correlates with decreased plasma nesfatin-1, serotonin, and oxytocin levels, while dopamine levels increase. The study's findings indicate that fasted dogs exhibited lower plasma levels of nesfatin-1, serotonin, and dopamine, while plasma oxytocin levels were higher. Furthermore, while the research findings do not suggest a significant relationship between the severity of aggression and the gender of the dog, male Pit Bull breeds appear to have higher plasma nesfatin-1 and serotonin levels compared to their female counterparts. The study's findings demonstrate that nesfatin-1, serotonin, oxytocin, and dopamine play pivotal roles in Pit Bull dogs' aggression, indicating potential interactions among these neuropeptides at the central nervous system level.

Assessment of serum markers in preeclampsia: A prospective study

Preeclampsia is a disease characterized by hypertension, proteinuria, and edema that occurs after the 20th gestational week. It is among the most important reasons for maternal/perinatal morbidity and mortality. Although many studies have been carried out, the pathophysiology of the disease is not fully known. Many methods have been proposed for evaluating risk factors leading to preeclampsia. In the past, the methods used to predict preeclampsia have usually been focused on non-biochemical markers, but nowadays there is a shift towards biochemical markers. Recently, many biochemical agents have been started to be used in the prediction of preeclampsia. In this study, the evaluation of some serum biomarkers in the follow-up preeclampsia was aimed. Serum nesfatin, ezrin, placental protein 13, hypoxia-inducible factor 1-α subunit (HIF1A), and neuropilin 1 levels were examined with the ELISA method. In the study, 90 samples taken from subjects, including pre-treatment preeclampsia (n =35), post-treatment preeclampsia (n = 35), and healthy control (n = 20) groups were evaluated. The data obtained from the study was analyzed with SPSS 22.0. As a result of the statistical analysis, pre-treatment nesfatin-1, and ezrin levels were found significantly lower than post-treatment and the healthy control group and HIF-1A levels were found significantly higher. As a result of these analyses, pre-treatment and post-treatment PP13 levels were found to be significantly higher than the healthy control group.Considering the results obtained from the study, we can say that nestin, ezrin, HIF1A, PP13, and NRP1 are important biomarkers for predicting preeclampsia.

The effect of aerobic and resistance training on Omentin-1 and Nesfatin-1 levels in adults: A systematic review and meta -Analysis

The effect of aerobic and resistance training on Omentin-1 and Nesfatin-1 levels in adults: A systematic review and meta -Analysis

Blood nesfatin-1 levels in patients with polycystic ovary syndrome: a systematic review and meta-analysis.

Previous studies have investigated the relationship between nesfatin-1 level and polycystic ovary syndrome (PCOS). However, these studies have produced conflicting results. Thus, in this meta-analysis, we aimed to clarify the association between blood nesfatin-1 levels and PCOS, and the ability of nesfatin-1 as a biomarker in PCOS. Meta-analysis was performed using STATA 12.0 software. We computed standard mean difference (SMD) and 95% confidence interval (CI) regarding the comparison of blood nesfatin-1 in patients with PCOS and controls. The present meta-analysis showed no significant difference in blood nesfatin-1 level between patients with PCOS and controls with a random effects model (SMD = 0.03; 95%CI: -0.71, 0.77; I2 = 97.1%, p value for Q test < 0.001). Subgroup analysis for different ethnicities reported no significant difference in blood nesfatin-1 level between patients with PCOS and controls in both Caucasian and Asian populations. Subgroup analysis for different sample types reported no significant difference in serum nesfatin-1 level between patients with PCOS and controls. Subgroup studies reported no significant difference in blood nesfatin-1 level between PCOS and controls in both obese and non-obese populations. In conclusion, there is no significant relationship between blood nesfatin-1 levels and PCOS.
