Unlabelled: We present the case of a patient with a history of symptomatic hypoglycaemic episodes and a negative 72-hour fasting test with histological confirmation of insulinoma. A literature review of hyperinsulinaemic hypoglycaemia with a negative fasting test was performed.
Learning Points: The 72-hour fasting test is the gold standard for insulinoma diagnosis.Few cases of insulinoma with a negative fasting test have been reported.New strategies for insulinoma diagnosis are being investigated.

Background: Obesity can arise from various physiological disorders. This research examined the impacts of the bacteriocin, gassericin A, which is generated by certain gut bacteria, using an in vivo model of obesity.
Methods: Fifty Swiss NIH mice were randomly assigned to five different groups.
Association of vitamin D receptor gene polymorphisms, metabolic features and susceptibility to polycystic ovary syndrome: a preliminary study.
Reprod Biomed Online

Research Question: Are the combined genotypes and haplotypes of vitamin D receptor (VDR) gene polymorphisms (FokI, ApaI and TaqI) associated with susceptibility to polycystic ovary syndrome (PCOS) and metabolic features of the disease?
Design: This case-control study included 46 women with PCOS and 48 controls. Genotypes of the VDR gene were determined using the polymerase chain reaction-restriction fragment length polymorphism method. Waist circumference, and parameters of lipid and glucose metabolism were evaluated in all women.
Adenylate kinase 5 deficiency impairs epididymal white adipose tissue homeostasis and decreases fat mass.

Importance: The brain and adipose tissue interact metabolically, and if there is a problem with the energy metabolism of the brain, it cannot maintain the energy balance with the adipose tissue. Therefore, when adenylate kinase 5 (), which regulates energy metabolism in the brain, is knocked out, problems with lipid metabolism may occur.
Objective: We aimed to elucidate the metabolic function and phenotype of , a gene with an unknown function in metabolism.

Purpose: Polycystic ovary syndrome (PCOS) is a frequent disorder among women. Exercise training has been known as an effective treatment for this disorder; however, there is small amount of evidence examining the optimal exercise programs. We evaluated the function of combined (COM) training on metabolic, hormonal parameters, and biomarkers of oxidative stress and inflammation in PCOS patients.

The first step to reducing the growing burden of cardiovascular disease (CVD) is to find modifiable risk factors with the highest burden in each population. Urban and rural citizens may have different priorities in this regard. This study aimed to compare the 10-year incidence probability of CVD events and its associated risk factors between rural and urban areas in Iran.
