Effects of hypertension on cerebral cortical thickness alterations in patients with type 2 diabetes

In 2013, a large cross-sectional survey based on 170, 287 people in China showed that the overall prevalence of total diabetes was up to 10.9% [1]. Previous study showed that type 2 diabetes mellitus(T2DM)increased the risk of various complications in multiple organs, including the brain [2]. T2DM related complications in the brain may accelerate cognitive dysfunction and even increase the risk of dementia [3,4]. We have recently shown that T2DM is associated with cerebral cortical thickness(CT) reduction and that CT reduction may explain the association between T2DM and cognitive dysfunction [5].

In this study, we found that cofilin competes with tau for direct microtubule binding in vitro, in cells, and in vivo, which inhibits tau-induced microtubule assembly. Genetic reduction of cofilin mitigates tauopathy and synaptic defects in Tau-P301S mice and movement deficits in tau transgenic C. elegans. The pathogenic effects of cofilin are selectively mediated by activated cofilin, as active but not inactive cofilin selectively interacts with tubulin, destabilizes microtubules, and promotes tauopathy. These results therefore indicate that activated cofilin plays an essential intermediary role in neurotoxic signaling th...

​BY FREDDIE IRIZARRY-DELGADO; VAROON KAKAIYA; &AHMED RAZIUDDIN, MDAn 86-year-old African-American woman was brought to the ED by her daughter after two days of nutritional neglect, abdominal pain, and altered mental status. Her daughter said her mother felt lightheaded, appeared dehydrated, and vomited nonbilious watery fluid once. The patient had a history of diabetes mellitus type 2, DVT/PE, dementia, and early signs of parkinsonism.Her vital signs were remarkable only for tachypnea (24 bpm). Her troponin I was markedly elevated at 1.7 ng/mL. A D-dimer was ordered because of her history of unprovoked DVT/PE, and it...

In this study, we aimed to develop an experimental animal model for type 2 diabetes mellitus (T2DM) using a combination of monosodium glutamate (MSG) and high sucrose diet (HSD). Young male Wistar rats (20-30 g) were injected with MSG (2 or 4 mg/g, i.p. for 4 days). These rats were also fed an HSD, while the control group was fed a starch diet (SFD) for 150 days. Parameters assessed periodically were body weight, feed intake, blood glucose level, and oral glucose tolerance test (OGTT), lipid profile, liver and kidney function tests, skeletal muscle glucose uptake, cognitive function tests, and microvascular changes using i...

Conclusions: IR is associated with impaired CVR; the relationship appears to be driven by the degree of IR and not by obesity. These rarely reported results suggest that early forms of cerebrovascular dysfunction exist among obese middle-aged individuals with significant IR but without type 2 diabetes mellitus. These functional vascular abnormalities may help explain the associations among IR, diabetes, and dementia, and suggest that interventions aiming to improve IR or CVR may help prevent cognitive decline later in life.

In conclusion, healthcare initiatives could be adopted in order to increase the understanding of the pathogenic contributions of each element on MetS and how they can be modified. These actions will be useful to reduce healthcare costs and can lead to more effective prevention of metabolic disease, thus promoting good health.

In conclusion, hTERT expression strictly limits telomerase activation in most of somatic cells, whereas mTERT expression is detectable in most of mouse tissue cells. The interspecies differences between human and mice suggest an improved mouse line, in which both telomerase regulation and telomere length controls are humanized, would considerably benefit the studies of human aging and cancer using mouse models.

The effects of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) on dementia risk in patients with type 2 diabetes mellitus (DM) and hypertension remain unknown. We investigated the effects of ACEIs and ARBs on dementia risk in patients with type 2 DM and hypertension.

Conclusions In conclusion, since there are now numerous animal and epidemiological studies indicating that environmental pollutants could contribute to the global obesity epidemic, there is an urgent need to reduce the burden of environmental contaminants so that obesity does not become the normal outlook in the future. The workshop attendees concluded that public health efforts should focus on the importance of early obesity prevention by means of reducing chemical exposures, rather than only treating the established disease. Just as a bad start can last a lifetime and beyond, a good start can last a lifetime as well. Re...
