Diagnosing insulin resistance promptly and accurately is essential for adequately managing and intervening in metabolic disorders. Several diagnostic methods have been developed to assess insulin resistance. However, each method has advantages and disadvantages. The most precise test is the hyperinsulinemic-euglycemic clamp, which examines the direct impact of insulin on glucose uptake by tissues. However, it is primarily utilized in research due to its complexity and intrusiveness. Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and the Quantitative Insulin Sensitivity Check Index (QUICKI) are the second most used Insulin resistance tests in the clinical setup. These tests are based on measuring the fasting glucose and insulin levels. The Oral Glucose Tolerance Test (OGTT), Insulin tolerance test, and the Matsuda Index are further diagnostic procedures that shed light on insulin sensitivity. The improved techniques, such as the insulin suppression test and the minimal model analysis, provide substitutes for unique clinical circumstances. Additionally, including extra measurements with these tests, like waist circumference, lipid profiles, and inflammatory markers, can improve the evaluation of insulin resistance. In summary, identifying insulin resistance is essential for the early detection and treatment of various metabolic illnesses. To make educated judgments and improve patient care, healthcare workers should be aware of the different available diagnostic tests and how they are used in each situation. Insulin resistance detection and monitoring will require further study to improve current diagnostic approaches and create novel, less invasive techniques.","PeriodicalId":13224,"journal":{"name":"Hormone Molecular Biology and Clinical Investigation","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141901586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hypoxia, ischemia, and oxidative stress induced by free radicals have been associated with development of PE. Ischemia-modified albumin (IMA) is a chemically modified albumin due to oxidative stress. IMA, a serum biomarker of hypoxia, ischemia, and oxidative free radicals is a potential biomarker for PE. The aim of the current proposal was to study serum IMA as a diagnostic biomarker of pre-eclampsia (PE) in pregnant females and to evaluate the correlation between serum IMA and different markers of pre-eclampsia (BP, urinary protein, LFT, KFT, serum total protein & uric acid).Methods: A total of 60 pregnant women aged between 21 and 35 years were recruited (30 PE cases and 30 normal pregnancy). Serum IMA was measured by spectrophotometric method developed by Bar-Or D. BP and biochemical parameters (urinary protein, LFT, KFT, serum total protein & uric acid) were also assayed and compared between two groups. Correlation analysis was done for analyzing the relationship between serum IMA and biochemical parameters.Results: The mean serum IMA was significantly higher in normotensive pregnant females (0.93 ABSU) than PE cases (0.71 ABSU). Kidney function and liver function parameters were more deranged in PE cases than in controls. Serum IMA was positively correlated with serum creatinine (r=0.322), serum uric acid (r=0.54) and urinary protein (0.376) whereas negatively correlated with total serum bilirubin (r=-0.515) and serum albumin (r=-0.380).Conclusions: Elevated serum IMA concentrations in normotensive pregnant controls as compared to PE cases suggest that apart from ongoing ischemia and oxidative stress in placenta IMA values are influenced by many other mechanisms in pregnancy.","PeriodicalId":13224,"journal":{"name":"Hormone Molecular Biology and Clinical Investigation","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141787878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of DR had no significant association with the prevalence of ACE I/D genotype compared to those without DR either in the recessive model (p=0.588) or in the dominant model (p=0.891).

MMP9 and MMP2 expression increased significantly in both cell lines under EGF treatment, and melatonin increased these genes' expression in both cell lines (p<0.05).

This study investigates the subsequent development of a novel Omicron sublineage, JN.1, which displays distinctive mutations in the spike protein. The study delves into the phylogenetic differences between these variants and their potential implications. A comprehensive analysis of the genomic profiles and mutation patterns of JN.1 and BA.2.86 was conducted, utilizing SARS-CoV-2 database. The study explores the unique mutations, such as S:L455S in JN.1, associated with increased transmissibility and immune escape. Furthermore, a comparison with prevalent strains like XBB.1.5 and HV.1 highlights the substantial genetic divergence of JN.1. JN.1, first detected in August 2023, exhibits a notable spike protein mutation profile, including the reappearance of earlier variants' mutations (E484K and P681R). The variant's increased transmissibility and immune evasion potential are attributed to specific spike protein mutations like R21T, S50L, V127F, R158G, and others. The study also explores the distribution and prevalence of JN.1 globally, with a focus on the rising cases in India. JN.1 poses a unique challenge as one of the most immune-evading variants, with potential implications for COVID-19 transmission. The study emphasizes the importance of monitoring and understanding emerging variants, especially those with distinct spike protein mutations. The observed cases in India highlight the need for vigilance and prompt public health responses. As JN.1 continues to evolve, ongoing surveillance, vaccination strategies, and adherence to preventive measures are crucial to mitigating its potential impact on global public health.","PeriodicalId":13224,"journal":{"name":"Hormone Molecular Biology and Clinical Investigation","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140694272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
