The objective of this study was to investigate the effect and the mechanism of action of fernenediol as insulin secretagogue. Wistar rats were treated with 0.1; 1 and 10 mg/kg fernenediol and then induced hyperglycemia by oral glucose. The glycaemia, insulin, LDH, calcium and hepatic glycogen were analyzed. Considering the intestine and pancreas as targets for the triterpene action, the duodenum was used to verify the influence of fernenediol on intestinal glycosidases. Additionally, pancreatic islets were used for studies of 14 C-deoxyglucose uptake and influx of 45 Ca2+ in hyperglycemic medium with/without fernenediol in the presence/absence of an inhibitor/activator of KATP channels, glibenclamide, diazoxide, nifedipine, calcium chelator (BAPTA- AM) and H-89 and ST the inhibitors of the PKA and PKC enzymes...

Obesity is a complex disease associated with environmental and genetic factors. 3-Iodothyronamine (T1AM) has revealed great potential as an effective weight loss drug. We used metabolomics and associated transcriptional gene and protein expression analysis to investigate the tissue specific metabolic reprogramming effects of subchronic T1AM treatment at two pharmacological daily doses (10 and 25 mg/kg) on targeted metabolic pathways. Multi-analytical results indicated that T1AM at 25 mg/kg can act as a novel master regulator of both glucose and lipid metabolism in mice through sirtuin-mediated pathways...

REVIEW
Harriet S Cheng, Marius Rademaker
Increasingly, existing evidence indicates that methotrexate-associated liver injury is related to comorbid risk factors such as diabetes, alcoholism, and obesity, rather than to methotrexate itself. Despite this fact, significant effort continues to be expended in the monitoring of low-dose methotrexate in patients with psoriasis. The gold standard investigation has been liver biopsy, but this is associated with significant morbidity and mortality. As methotrexate-induced liver injury is uncommon, the risk/benefit ratio of liver biopsy has been questioned...

The association between type 1 diabetes mellitus (T1DM) and bone health has garnered interest over the years. Fracture risk is known to be increased in individuals with T1DM, although bone health assessment is not often performed in the clinical setting. We describe the case of a 21-year-old male with longstanding T1DM with multilevel vertebral fractures on imaging, after presenting with acute back pain without apparent trauma. Dual-energy X-ray absorptiometry (DXA) revealed significantly reduced bone mineral density at the lumbar spine and femoral neck...

The chemiresistive sensing characteristics of metal oxide gas sensors depend closely on ambient humidity. Herein, we report that gas sensors using Tb-doped SnO2 yolk-shell spheres can be used for reliable acetone detection regardless of the variations in humidity. Pure SnO2 and Tb-doped SnO2 yolk-shell spheres were prepared via ultrasonic spray pyrolysis and their chemiresistive sensing characteristics were studied. The sensor resistance and gas response of the pure SnO2 yolk-shell spheres significantly changed and deteriorated upon exposure to moisture...

Diabetes mellitus is a group of metabolic disorders characterized by elevated blood sugar and abnormalities in insulin secretion and action. There are many anti-diabetic plants, which might supply useful sources for developing new medicines that can be used in treatment of diabetes mellitus. The primary objective of the present investigation is to evaluate the anti-diabetic properties of the aerial parts of Amygdalus lycioides in streptozocin-induced diabetic rats. Sixty rats were divided into 6 groups: streptozocin-induced diabetic control, insulin-treated diabetic group, and four Amygdalus lycioides -treated diabetic groups (125, 250, 500, and 1000 mg/kg/day)...

REVIEW
Mohamed A A Mahdy
Skeletal muscle regenerates efficiently following injuries and diseases. However, muscle regeneration is compromised in several conditions by adipocyte infiltration and excessive collagen deposition. Adipocyte infiltration is a characteristic feature of sarcopenia, diabetes, cachexia, muscular dystrophies and advanced cases of Duchenne muscular dystrophy (DMD), while excessive collagen deposition is a hallmark of muscular dystrophies and severe muscle injuries, such as lacerations, contusions and strains. Muscle adipogenesis and fibrosis are major causes of muscle weakness that impairs muscle function...

Among women in Taiwan, thyroid cancer is the fifth most common malignant neoplasia. However, genomic profiling of papillary thyroid cancer (PTC) cases from Taiwan has not been attempted previously. We used whole-exome sequencing to identify mutations in a cohort of 19 PTC patients. Sequencing was performed using the Illumina system; Sanger sequencing was used to validate all identified mutations. We identified new somatic mutations in APC, DICER1, LRRC8D and NDRG1. We also found somatic mutations in ARID5A, CREB3L2, MDM4, PPP2R5A and TFPT; mutations in these genes had been found previously in other tumors, but had not been described previously in PTC...

Diabetes-associated nociceptive hypersensitivity affects diabetic patients with hard-to-treat chronic pain. Because multiple tissues are affected by systemic alterations in insulin signaling, the functional locus of insulin signaling in diabetes-associated hypersensitivity remains obscure. Here, we used Drosophila nociception/nociceptive sensitization assays to investigate the role of Insulin receptor (Insulin-like receptor, InR) in nociceptive hypersensitivity. InR mutant larvae exhibited mostly normal baseline thermal nociception (absence of injury) and normal acute thermal hypersensitivity following UV-induced injury...
