Echo time optimization for in-vivo measurement of unsaturated lipid resonances using J-difference-edited MRS.

Purpose: Measuring lipid composition provides more information than just total lipid content. Hence, the non-invasive measurement of unsaturated lipid protons with both high efficiency and precision is of pressing need. This study was to optimize echo time (TE) for the best resolving of J-difference editing of unsaturated lipid resonances.

4-Octyl itaconate attenuates glycemic deterioration by regulating macrophage polarization in mouse models of type 1 diabetes.

Background: Pancreatic beta cell dysfunction and activated macrophage infiltration are early features in type 1 diabetes pathogenesis. A tricarboxylic acid cycle metabolite that can strongly activate NF-E2-related factor 2 (Nrf2) in macrophages, itaconate is important in a series of inflammatory-associated diseases via anti-inflammatory and antioxidant properties. However, its role in type 1 diabetes is unclear.

Automated Measurement of Pancreatic Fat Deposition on Dixon MRI Using nnU-Net.

Background: Pancreatic fat accumulation may cause or aggravate the process of acute pancreatitis, β-cell dysfunction, T2DM disease, and even be associated with pancreatic tumors. The pathophysiology of fatty pancreas remains overlooked and lacks effective imaging diagnostics.

Purpose: To automatically measure the distribution of pancreatic fat deposition on Dixon MRI in multicenter/population datasets using nnU-Net models.

Clinical and genetic analysis of pseudohypoparathyroidism complicated by hypokalemia: a case report and review of the literature.

Background: Pseudohypoparathyroidism (PHP) encompasses a highly heterogenous group of disorders, characterized by parathyroid hormone (PTH) resistance caused by mutations in the GNAS gene or other upstream targets. Here, we investigate the characteristics of a female patient diagnosed with PHP complicated with hypokalemia, and her family members.

Case Presentation And Gene Analysis: A 27-year-old female patient occasionally exhibited asymptomatic hypocalcemia and hypokalemia during her pregnancy 1 year ago.

Metabolic Syndrome and Its Components Are Associated With Altered Amino Acid Profile in Chinese Han Population.

Objective: Recent studies have found that the levels of plasma amino acids, such as branched-chain amino acids and aromatic amino acids, were associated with visceral obesity, insulin resistance, future development of diabetes and cardiovascular diseases. However, few studies have involved a Chinese Han population. This study aimed to examine the association between amino acid profile and metabolic syndrome (MetS) and its components in the Chinese Han population.

CircRNF111 Protects Against Insulin Resistance and Lipid Deposition via Regulating miR-143-3p/IGF2R Axis in Metabolic Syndrome.

Abnormal expression of circRNAs (circular RNAs), a subclass of non-coding RNAs, has been documented in numerous human diseases. Herein, we explored whether circRNAs act as ceRNAs (competing endogenous RNAs) to modulate the pathological process-insulin resistance, as well as dyslipidemia of MetS (Metabolic Syndrome). The profile of circRNAs in serume of MetS and control samples was characterized by circRNA deep sequencing.

Knockdown of insulin-like growth factor 2 gene disrupts mitochondrial functions in the liver.

Even though insulin-like growth factor 2 (IGF2) has been reported to be overexpressed in nonalcoholic fatty liver disease (NAFLD), its role in the progression of NAFLD and the potential mechanism remain largely unclear. Using in vitro models, we found that IGF2 was the key overexpressed gene in steatosis, suggesting a possible association between IGF2 and NAFLD. Interestingly, loss-of-function experiments revealed that inhibition of IGF2 protein impaired mitochondrial biogenesis and respiration.

Small cell lung cancer with panhypopituitarism due to ectopic adrenocorticotropic hormone syndrome: A case report.

Background: Small cell lung cancer (SCLC) accounts for 15% of lung cancers, and it commonly expresses peptide and protein factors that are active as hormones. These secreting factors manifest as paraneoplastic disorders, such as ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS). The clinical features are abnormalities in carbohydrate metabolism, hypokalemia, peripheral edema, proximal myopathy, hypertension, hyperpigmentation, and severe systemic infection.

Liraglutide ameliorates cognitive decline by promoting autophagy via the AMP-activated protein kinase/mammalian target of rapamycin pathway in a streptozotocin-induced mouse model of diabetes.

Diabetic cognitive dysfunction has gained widespread attention for its deleterious impact on individuals with diabetes. However, few clinical interventions are available to prevent the disorder. The glucagon-like peptide-1 analog liraglutide exerts neuroprotective effects in several models of neurodegenerative diseases.

The endoplasmic reticulum stress/autophagy pathway is involved in cholesterol-induced pancreatic β-cell injury.

Lipotoxicity has been implicated in pancreatic β-cell dysfunction in type 2 diabetes, but the exact mechanisms remain unknown. The current study explored the role of the endoplasmic reticulum (ER) stress pathway in cholesterol-induced lipotoxicity. Two different insulinoma cell lines were treated with cholesterol with or without inhibitors.

Clinical analysis of 65 cases of hyperemesis gravidarum with gestational transient thyrotoxicosis.

Aim: We investigated thyroid function and the impact of gestational transient thyrotoxicosis (GTT) on pregnancy outcome in patients with hyperemesis gravidarum (HG; n = 143) who were hospitalized for rehydration.

Methods: Serum thyroid-stimulating hormone (TSH), free T3 (FT3), free T4 (FT4), thyroid globulin antibody (TgAb), thyroid peroxidase antibody (TPOAb) and hCG were measured after admission.

Results: The total prevalence of thyrotoxicosis in HG was 48.
