Cellular circadian period length inversely correlates with HbA 1c levels in individuals with type 2 diabetes

AbstractAims/hypothesisThe circadian system plays an essential role in regulating the timing of human metabolism. Indeed, circadian misalignment is strongly associated with high rates of metabolic disorders. The properties of the circadian oscillator can be measured in cells cultured in vitro and these cellular rhythms are highly informative of the physiological circadian rhythm in vivo. We aimed to discover whether molecular properties of the circadian oscillator are altered as a result of type 2 diabetes.MethodsWe assessed molecular clock properties in dermal fibroblasts established from skin biopsies taken from nine obese and eight non-obese individuals with type 2 diabetes and 11 non-diabetic control individuals. Following in vitro synchronisation, primary fibroblast cultures were subjected to continuous assessment of circadian bioluminescence profiles based on lentiviral luciferase reporters.ResultsWe observed a significant inverse correlation ( ρ = −0.592;p

Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...

AbstractObjectivesDiabetic scleredema (DS) is reported rarely in China and its features are poorly documented. We aim to describe the characteristics of Chinese patients with DS clinically, radiologically, and histologically.MethodsOf 9825 hospitalized participants with diabetes older than 18  years, 15 type 2 diabetes patients with DS as well as 15 non-DS patients with type 2 diabetes were included in this observational study.ResultsAll the individuals with DS presented diffuse erythema, non-pitting, and painless indurations on the skin of the nape and upper back. Patients with DS were mainly middle-aged or elderly (...

This study suggests that exocrine glands can be induced from pluripotent stem cells for organ replacement regenerative therapy. Replacement of Aged Microglia Partially Reverses Cognitive Decline in Mice https://www.fightaging.org/archives/2018/10/replacement-of-aged-microglia-partially-reverses-cognitive-decline-in-mice/ Researchers here report on a compelling demonstration that shows the degree to which dysfunctional microglia contribute to age-related neurodegeneration. The scientists use a pharmacological approach to greatly deplete the microglial population and then allow it to recover naturally. The...

Abstract Calciphylaxis is a rare disease characterized by calcification of small- to medium-sized blood vessels in the dermis and subcutaneous fat, resulting in cutaneous necrosis. Although most commonly shown in patients with end-stage kidney disease, it has also been reported in patients with other diseases, including alcoholic cirrhosis and malignancies. Here, we report an unusual case of calciphylaxis in an orthotopic liver transplant recipient with acute kidney injury. The patient, a 43-year-old white female with a history of type 2 diabetes mellitus, alcoholic cirrhosis, and normal kidney function, presented...

Conclusions: Peroral arsenic has little effect on local airway immune responses to bacteria but compromises respiratory epithelial barrier integrity, increasing systemic translocation of inhaled pathogens and small molecules. https://doi.org/10.1289/EHP1878 Received: 09 March 2017 Revised: 14 August 2017 Accepted: 16 August 2017 Published: 28 September 2017 Address correspondence to M.B.

Conclusion: To address the many challenges posed by EDCs, we argue that Africans should take the lead in prioritization and evaluation of environmental hazards, including EDCs. We recommend the institution of education and training programs for chemical users, adoption of the precautionary principle, establishment of biomonitoring programs, and funding of community-based epidemiology and wildlife research programs led and funded by African institutes and private companies. https://doi.org/10.1289/EHP1774 Received: 16 February 2017 Revised: 22 May 2017 Accepted: 24 May 2017 Published: 22 August 2017 Address correspond...

In this study, researchers analysed data of millions of British patients between 1995 and 2015 to see if this claim held true. They tracked people who were obese at the start of the study, defined as people with a body mass index (BMI) of 30 or more, who had no evidence of heart disease, high blood pressure, high cholesterol or diabetes at this point. They found these people who were obese but "metabolically healthy" were at higher risk of developing heart disease, strokes and heart failure than people of normal weight. No such thing as 'fat but fit', major study finds Several studies in the pas...

Recruitment of brown adipose tissue (BAT) has emerged as a potential tool to combat obesity and associated metabolic complications. Short-term cold acclimation has been shown not only to enhance the presence and activity of BAT in lean humans but also to improve the metabolic profile of skeletal muscle to benefit glucose uptake in patients with type 2 diabetes. Here we examined whether short-term cold acclimation also induced such adaptations in 10 metabolically healthy obese male subjects. A 10-day cold acclimation period resulted in increased cold-induced glucose uptake in BAT, as assessed by [18F]fluorodeoxyglucose posi...

Discussion This is the first randomised clinical trial assessing dipeptidyl peptidase-4 inhibition therapy in psoriasis. We hypothesise that sitagliptin therapy in combination with NB-UVB improves psoriasis severity compared to NB-UVB monotherapy. Trial registration ClinicalTrials.gov Identifier NCT02347501 (Date of registration: 27 January 2015).
