Preparation of novel berberine nano-colloids for improving wound healing of diabetic rats by acting Sirt1/NF-κB pathway

Publication date: Available online 14 November 2019Source: Colloids and Surfaces B: BiointerfacesAuthor(s): Peng Zhang, Libang He, Jie Zhang, Xifan Mei, Yiyao Zhang, He Tian, Zhenhua ChenAbstractIn the present work, novel berberine nano-colloids hydrogel (BNH) was prepared for improving wound healing of diabetic rats. Polyvinyl alcohol (PVA), sodium alginate (Alg) were adopted as building blocks to form BNH. Calcium ions was used as crosslink agent to construct BNH. The skin injury model of diabetic rats was successfully established, and the prepared hydrogel was applied to the wound. Animal experiments proved that BNH could promote wound healing of diabetic rats. Further molecular mechanism research revealed that BNH could inhibit the expression of NF-κB, TNF-a and IL-6, but increase the expression of F VEGF, CD 31 and SMA by activating Sirt 1 which were benefit for wound healing of diabetic rats.Graphical abstract

(Broad Institute of MIT and Harvard) Researchers tested approximately 4,518 drug compounds on 578 human cancer cell lines and found nearly 50 that have previously unrecognized anti-cancer activity. These drugs have been used to treat conditions such as diabetes, inflammation, alcoholism, and even arthritis in dogs. The findings suggest a possible way to accelerate the development of new cancer drugs or repurpose existing drugs to treat cancer.

I am continually amused by the claims of Trumpistas that the U.S. is experiencing an economic resurgence and utopia, for which of course the vulgarian in chief deserves all the credit. Joseph Stiglitz, who unlike them and me has won a Nobel Memorial Prize in economics (it's not a real Nobel prize, economists added it later because they wanted one too)knows otherwise.This is a fairly dense essay which it's difficult to summarize without quoting, but I'll try. Meanwhile one pull quote:Two years ago, a few rare corporate leaders were concerned about climate change, or upset at Trump ’s misogyny and bigotry. Most, howeve...

In this report, we present the case of a patient who was diagnosed with primary biliary cholangitis and metabolic syndrome. Initial evaluation also revealed diabetes with elevated fasting plasma glucose and glycated hemoglobin. After eight weeks of treatment with ursodeoxycholic acid, a complete normalization of the hepatic biological tests was observed. A few months later, while body weight and abdominal perimeter remained stable, fasting blood glucose and glycated hemoglobin decreased significantly, compatible with diabetes disappearance. This finding supports the concept that the inflamed liver plays a major role in the...

Conclusions: Patients with comorbidities such as chronic obstructive pulmonary disease, obesity, diabetes, and alcoholism are a high-risk group for VAP. Particular attention should be paid to patients admitted to the ICU with multi-organ trauma, fractures, and hemorrhage/hemorrhagic shock as patients predisposed to VAP. There is a need for further research into risk factors for non-modifiable VAP such as comorbidities and reasons for ICU admission in order to allow closer monitoring of these patients for VAP.

We describe evidence for substance use as a risk factor for new-onset diabetes, prevalence of use in people with diabetes, evidence linking substance use with diabetes-related health outcomes, and evidence on the management of these co-occurring conditions.

Background: Hypertension is a well-known risk factor for intracerebral hemorrhage (ICH). On many of the other potential risk factors, such as smoking, diabetes, and alcohol intake, results are conflicting. We assessed risk factors of ICH, taking also into account prior depression and fatigue. Methods: This is a population-based case-control study of 250 primary ICH patients, conducted in Helsinki University Hospital, Finland. The controls (n  = 750) were participants of the FINRISK study, a large Finnish population survey on risk factors of chronic noncommunicable diseases, matched with cases by sex and age.

Publication date: Available online 15 January 2020Source: Aggression and Violent BehaviorAuthor(s): Tobore Onojighofia ToboreAbstractAlcohol use is known to result in disinhibition. However, evidence suggests that alcohol consumption could also result in inhibition. Several hypotheses have been proposed for this confounding alcohol-induced behavior, but none explains it adequately at the level of the brain. In this paper, oxidative stress is put forth as the underlying cause of alcohol toxicity and behavioral impairments. The implications of this understanding and how oxidative stress influences behavior in obesity, diabet...
