Nerve damage happen as a result of many factors including metabolic disorders, oxidative and nitrosative stress, changes in the blood vessels that supply the peripheral nerves and changes in ion channel expression in peripheral fibres. However, the molecular basis for DN is poorly understood. Adenosine monophosphate activated protein kinase (AMPK) has been shown to regulate the activity of some kinases including protein kinase B (AKT), mitogen-activated protein kinases (MAPK) and mammalian target of rapamycin complex 1 (mTORC1) that represent important signalling pathways modulating the function of peripheral nociceptive neurons. Donepezil can activate AMPK and exerts neuroprotective effects. Diabetic mice showed reduced expression of p-AMPK in sciatic nerves with consequent activation of AKT/MAPK/4EBP1. In addition, a significant upregulation of the N-Methyl-D-aspartate (NMDA) receptors in spinal cord of diabetic mice was observed. Therefore, Donepezil could be a potential pharmacological agent for management of DN.","PeriodicalId":21118,"journal":{"name":"Records of Pharmaceutical and Biomedical Sciences","volume":"204 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78764450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many findings describe the roles of over nutrition-associated hypothalamic inflammation in neurodegeneration and impaired adult neurogenesis as well as defective neural stem cell regeneration and their significance in obesity and related disease. Metabolic disorders include oxidative stress, insulin resistance, obesity and inflammation. Collectively, metabolic syndrome perturbs brain function and increases the incidence of neurodegenerative diseases, reflecting the possible involvement of obesity induced metabolic syndrome in development of Alzheimer's disease (AD) which is the most common form of dementia. Its key symptoms include progressive decline in the memory, impairment in speech, language, spatial orientation and dysfunction in the sensor motor system . Alzheimer's disease (AD) is a chronic neurodegenerative disease that usually start slowly and worsens over time. It is the cause of 60-70% of cases of dementia .

The main chemical constituents of Ulva lactuca methanolic crude extract and its fractions were investigated in this study using different phytochemical and chromatographic methods. Biologically guided fractionation of plants or seaweeds extracts is considered the first step in drug discovery. So, the algal crude extract was fractionated then in vitro bioscreened for the determination of diphenylpicrylhydrazyl (DPPH) antioxidant, (Nitric Oxide) NO radical scavenging and anti-inflammatory activities. Results showed that water fraction was the most active fraction. Phenolic content, detected from HPLC, play a role in the antioxidant activity.

In cross-sectional studies, T2DM had various adverse health effects, including cognitive impairment. The association of T2DM with decreased cognitive function suggests that T2DM can contribute to Alzheimer's disease (AD) The relationship between T2DM and AD continues to grow rapidly. It has been suggested that AD can be considered \"type 3 diabetes”. Along with the processing of amyloid precursor protein (APP) and tau phosphorylation, the molecular links between T2DM and AD provide clues for new therapeutic targets such as glucagon-like peptide-1 (GLP-1), butyrylcholinesterase and receptor for advanced glycosylation end products (AGE). A possible mechanism correlating T2DM and AD is the alteration in insulin signaling in the brain. Insulin signaling is involved in several neuronal functions, and plays a vital role in the pathophysiology of AD. Therefore, the modification of neuronal insulin signaling by diabetic conditions may contribute to AD progression. Another possible mechanism is cerebrovascular changes, a common pathological change observed in both diseases. The importance of amyloid beta peptide (Aβ) induced cerebrovascular dysfunction in AD has been reported, indicating that pathological interactions between AGE receptor and Aβ have a role in this disorder.","PeriodicalId":21118,"journal":{"name":"Records of Pharmaceutical and Biomedical Sciences","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91239308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our study, we found that the Alpha diversity was enriched in obese men than obese females this may be due to the hormonal disturbance in the females which make the change in immunity and thereby, change in richness and diversity of gut microbiota composition.

Thymelaeaceae family have been the subject of numerous phytochemical studies. Initially, interest may have been due to the marked toxicity of these plants, but the widespread use of some species medicinally was certainly a reason for this interest. Thymelaea hirsuta is a perennial, evergreen and dioecious shrub, which is native to North Africa. Thymelaea hirsuta is a widespread invasive weed, is commonly known as “Methnane” and has been used traditionally as having antiseptic, antimelanogenesis, antioxidant and diabetic. There are numerous phytochemical studies lead to its richness in a variety of different classes of natural products, especially, coumarins, lignans, steroids and flavones. In addition, it used as a new fiber source for handmade paper.
