NPY is abundantly expressed in the extended amygdala and is critically involved in the regulation of negative affective states in rats, also is involved with neurobiological responses to ethanol and other drug of abuse. Genetic, molecular and pharmacological evidences suggest that NPY is an important neurobiological substrate for the predisposition to alcoholism. Administration, as well as the withdrawal of ethanol, alters central NPY expression. Alcohol-preferring rats exhibit basal NPY deficits in central amygdala. In the latter, NPY may rescue dependence-induced increases in anxiety and alcohol drinking. Low NPY levels in some brain regions following ethanol withdrawal contribute to the increased sensitivity to seizure and the heightened levels of anxiety characteristic of withdrawal responses. Mice with deletion of NPY gene exhibit a high-anxiety, high-alcohol-drinking phenotype. Pharmacological and genetic manipulations suggest that central NPY signaling modulates ethanol consumption via Y1, Y2, and Y5 receptors. Analysis of chromosomal regions (QTLs) associated with alcohol consumption identified NPY as one of the genes that influence alcohol dependence and as a promising target for pharmacotherapeutics to combat alcohol associated disorders. Consequently, NPY is a potentially new pharmacological target for the treatment of alcohol diseases.","PeriodicalId":8906,"journal":{"name":"Biomedical Reviews","volume":"68 1","pages":"27-40"},"PeriodicalIF":0.0,"publicationDate":"2017-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85208577","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 this context, nanorobotics has emerged as a highly-advanced technology for designing the fully functional smart devices or robots at nano scale. Development of these highly-controlled and functional nanostructures for sensing, information processing, signaling, and actuation may provide remarkable breakthroughs in medicine such as the improved imaging or targeted therapeutic interventions. Besides the detection and destroying the toxic materials and ecosystem restoration, the stimuli-responsive nanorobots may be used for the diagnosis or treatment of cardiac disorders, traumatic injuries, diabetes, and bacterial or viral infections. These molecular tools with nanoscale resolution facilitates early diagnosis in cancer and precise localization of anticancer agents leading to the minimal side effects. Nanorobots may easily traverse the human body and repair the cells or assist an improper functioning organ. These tiny devices integrated with wireless locomotion, external or internal power supply, artificial intelligence, and smart sensors may also be used for targeted delivery of genes or drugs into the single cells or tissues, tele-operation, or patient monitoring. Indeed, development of the medical nanorobots with a wide range of capabilities is a proof of concept and art in modern science and a breakthrough in nanotechnology which has been highlighted in the present manuscript.","PeriodicalId":8906,"journal":{"name":"Biomedical Reviews","volume":"101 2 1","pages":"19-26"},"PeriodicalIF":0.0,"publicationDate":"2017-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77264371","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}

Resveratrol, a polyphenolic compound which is found in various plant species, has emerged as a promising nutraceutical with therapeutic potentials in neuropsychiatric, cardiometabolic and cancer diseases, also aging. The abundance of research providing promising findings about the multi-spectrum therapeutic applications of resveratrol and its encouraging potential to treat or prevent chronic and age-related disorders has raised a considerable number of clinical trials. Recently, resveratrol is implicated the biology of nerve growth factor (NGF), a critical player in the maintenance of neuronal growth and function. Furthermore, resveratrol affects the endocannabinoid signalling (eCBs) which exerts modulatory effects in the survival signalling pathways, neural plasticity, and a variety of neuroinflammatory and neurodegenerative processes. The therapeutic effects of this ubiquitous signalling system in Alzheimer’s disease, epilepsy, multiple sclerosis, mood and movement disorders, spinal cord injury, and stroke have been well-documented. In the present review, the implication of NGF and eCBs in the mechanism of action of resveratrol, that may be of therapeutic significance in neurological and non-neurological disorders, is highlighted.

Generally, herbal and plant-derived products containing multiple compounds are administered orally for therapeutic purposes. Currently, targeted drug-delivery systems are being developed and investigated for the treatment of cardio-respiratory disorders, pain relief, wound healing, and life threatening diseases like cancers. A number of novel nanofiber membranes and devices are available for sustained release and to deliver steady supply of natural bioactive ingredients, herbal-based extracts, and a few have been approved by US-FDA and other drug regulatory agencies. The purpose of this mini review is to provide an update on the role of nanofiber devices used for the targeted-delivery of therapeutically active ingredients of plant and herbal origin as well as to underscore the potential for the delivery of cost-effective herbal ingredients and natural plant-based extracts for their biomedical applications in wound healing, inflammation-related diseases and cancer treatment.

Most authors suggest that higher serum cholesterol may be associated with a lower risk of Parkinson`s disease. Debates exist as to whether essential tremor shares similar neuropathological mechanisms as Parkinson`s disease. We investigated serum total cholesterol and triglyceride levels in a clinical setting of Parkinson`s disease versus essential tremor patients. Two hundred and sixteen Parkinson`s disease patients (126 males), aged 68.04 years, with 4.58 years disease duration and 342 essential tremor patients (118 males), aged 69.39 years, with 5.3 years disease duration were included, hospitalized during a period of 7 years in First Clinic of Neurology, University St Marina Hospital, Varna, Bulgaria. We found insignificantly higher levels of serum total cholesterol and triglyceride in essential tremor patients. Results differ statistically only on gender level with increased cholesterol in males and triglycerides in females.
