Advances in the knowledge of the microbiota and concepts related to it have triggered a wake-up call in biomedicine. The development in various scientific areas has enabled a better and broader approach to everything concerning the set of families of microorganisms that coexist with an individual and are able to function as one more organ in its body. Among the aforementioned scientific areas, those worth mentioning are the advances/progress in biotechnological resources and, in particular, molecular biology and related areas...

Multiple classes of natural products, such as antiandrogens or steroids have been used as antioxidants and anti-inflammatory treatments in neurodegenerative diseases. This paper aims to review current knowledge on these substances and their possible relationship with free radicals as an alternative therapy and prevention of common neurological disorders. An exhaustive review of the neurochemical mechanisms of these substances in the central nervous system of humans and animal models has yet to be undertaken in the literature, particularly regarding their importance and increasing use...

Generation of nascent functional neurons from neural stem cells in the adult brain has recently become largely accepted by the neuroscience community. In adult mammals including humans, the process of neurogenesis has been well documented in two brain regions; the subventricular zone of the lateral ventricles and the subgranular zone in the dentate gyrus of the hippocampus. Some evidence has indicated neurogenesis in other regions of the adult mammalian brain such as the neocortex, cerebellum, striatum, amygdala and hypothalamus...

Despite the great effort spent over the last decades to unravel the pathological mechanisms underpinning the development of central nervous system disorders, most of them remain still unclear. In particular, the study of rare brain diseases is hurdled by the lack of post-mortem samples and of reliable epidemiological studies, thus the setting of in vitro modeling systems appears essential to dissect the puzzle of genetic and environmental alterations affecting neural cells viability and functionality The isolation and expansion in vitro of embryonic (ESC) and fetal neural stem cells (NSC) from human tissue has efficiently allowed to model several neurological diseases "in a dish" and has also provided a novel platform to test potential therapeutic strategies in a pre-clinical setting...

Huntington's disease (HD) is an autosomal-dominant, progressive neurodegenerative disease characterized by selective loss of neurons in the striatum and cortex, which leads to progressive motor dysfunction, cognitive decline and behavioral symptoms. HD is caused by a trinucleotide (CAG) repeat expansion in the gene encoding for huntingtin (HTT). Despite the fact that the HD gene was identified over 20 years ago, there is no effective disease-modifying therapy for HD and only symptomatic therapies are available to date...

Parkinson's disease (PD) is the most prevalent movement disorder in the world. The major pathological hallmarks of PD are death of dopaminergic neurons and the formation of Lewy bodies. To the moment, there is no cure for PD; current treatments are symptomatic. Investigators are searching for neuroprotective agents and disease modifying strategies to slow the progress of PD. However, due to ignorance of the main pathological sequence of PD, many drug targets failed recently to provide neuroprotective effects in human trials...

BACKGROUND: Brain-derived neurotrophic factor (BDNF) plays a crucial role in promoting survival and differentiation of neurons and neural stem cells (NSCs), but the downstream regulating mechanisms remain poorly understood. OBJECTIVE: We investigated whether BDNF exerts its effect by triggering the phosphoinositide 3-kinase (PI3K), protein kinase B, PKB (AKT), glycogen synthase kinase-3β (GSK-3β) and β-catenin signaling pathway in cultured neurons and NSCs derived from the rat embryonic spinal cord...

Status epilepticus (SE), which can cause neuronal injury, neuronal death and alteration of neuronal networks, is characterized by high mortality and morbidity. Recently, inflammation was shown to play a significant role in SE pathogenesis. We also found that microRNA-146a was highly expressed in SE rats with severe inflammation. The role of miRNA-146a in the inflammatory response of SE is not clear. Thus, in our study, we investigated the relationship between inflammation and miR-146a expression. We assessed the effects of thymoquinone, an anti-inflammatory drug, and found it had a neuroprotective effect on SE by inhibiting the inflammatory reaction...

Ketamine, a noncompetitive NMDA receptor antagonist, exhibits a rapid antidepressant effect, but the underlying mechanism remains obscure. Ketamine and imipramine, a tricyclic antidepressant, share the same targets on AMPA receptors and CREB, whereas ketamine exerts fast-actioning responses compared to traditional antidepressants' slow onset. To figure out why there is a significant discrepancy of their antidepressant efficiency is important for elucidating the mechanisms underlying ketamine's antidepressant effects as well as discovering new rapid antidepressants...

Worldwide, at least 2.8 million people die each year as a result of being overweight or obese, that causes about 35.8 million (2.3%) of global Disability-Adjusted Life Year (DALYs). Obesity leads to metabolic syndrome, a pathological condition characterized by adverse metabolic effects on blood pressure, cholesterol, triglycerides and insulin resistance. Population-based investigations have suggested that obesity and metabolic syndrome may be associated with poorer cognitive performance and could be considered a possible risk factor for vascular Dementia and Alzheimer's Disease...

Delta (9)-tetrahydrocannabinol is the main psychoactive compound in cannabis and is commonly identified in blood samples from arrested drivers assumed to drive under the influence of drugs. Changing social norms towards cannabis and higher acceptability towards the drug emphasize the need for comprehensive understanding of the severe neurocognitive and psychomotor effects caused by cannabis and how these effects are correlated to driving skills and performance. In this review, PubMed, Cochrane Central, Scopus, Web of Science, Science Direct and EMBASE databases were used to identify and select publications up to January 2017 dealing with acute and chronic neurocognitive effects induced by cannabis and ability to drive...

A considerable amount of data suggests the age-related impairments of mitochondrial functions in the development of sporadic forms of neurodegenerative pathologies. These includes a decrease in the calcium retention capacity of mitochondria, which leads to the disturbance of the functional activity of neurons, and increased sensitivity of mitochondria towards the induction of the permeability transition. This in turn provoke the neuronal death enhancing the development of neurodegenerative processes. Inhibitors of mitochondrial permeability transition, which increases calcium retention capacity of mitochondria, are considered as promising neuroprotective drugs able not only to halt the neurodegenerative cascade, but also to increase the functional activity of neurons...

Since ancient times it is well documented the use of cannabis as a medicine due to its potential therapeutic activity while subsequently its use as drug of abuse spread increasingly. The present review sought to give an insight in the history of medical and recreational use of cannabis in India. Indian use of cannabis dates back to Vedic time, mostly for the ritualistic and religious purposed, as documented in the ancient literature. It was India that introduced the medical use of cannabis to neighboring countries...

Concurrent use of cannabis and alcohol is frequent. According different studies, the prevalence is among 20-34% depending on different samples studied. In contrast with the wide evidence available about neuropsychiatric effects associated to the use of cannabis or alcohol separately, there are few studies of the neuropsychiatric effects of their combination. Our aim was to review the literature regarding this topic. We performed a search in MEDLINE and from 114 potentially eligible studies, 27 were selected...

Treatment resistant depression (TRD) and suicidal behavior are among the most important public health problems and are commonly associated with significant disability and psychosocial impairment. Although there have been recent advances in identifying neurobiological correlates of these complex conditions, their pathophysiology still remains unclear. Although the recent advances concerning the neurobiological determinants underlying these complex conditions, their pathophysiology still remains unclear. Compared to non-suicidal subjects, higher mean concentrations of inflammatory mediators have been found in both the periphery and brain of individuals at risk for suicide...

Synthetic Cannabinoids (SC) are the widest and most diffused class of Novel Psychoactive Substances. SC are chemically heterogeneous and structurally dissimilar from delta-9-tetrahydrocannabinol, being full agonists of the endocannabinoid system receptors CB1 and CB2. Desired effects include euphoria, talkativeness, feelings of joy and laughter, relaxation. With respect to cannabis, SC intake may also be associated with quicker arise of the effects, shorter duration of action, and larger levels of hangover...

Cannabis is the most widely used illicit drug. The two most important natural cannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). The THC content of cannabis has been increasing during the last years and recently appeared in the market a series of synthetic cannabinoids with potent agonist activity. Recreational users frequently combine cannabis with other drugs of abuse as alcohol, amphetamines and derivatives, nicotine and cocaine. In addition these subjects can be taking medicines for acute and chronic medical conditions...

Medical cannabis is increasingly used as a treatment or adjunct treatment with different levels of efficacy in several neurological disorders or related symptoms (such as multiple sclerosis, autism, Parkinson and Alzheimer disease, Tourette's syndrome, Huntington's disease, neuropathic pain, epilepsy, headache), as well as in other medical conditions (e.g. nausea and vomiting, glaucoma, appetite stimulation, cancer, inflammatory conditions, asthma). Nevertheless, a number of neurological adverse effects from use of medical cannabis on the short- and on the long- term have been reported, in addition to other adverse health events...

BACKGROUND: Cannabidiol (CBD) is among the major secondary metabolites of Cannabis devoid of the delta-9-tetra-hydrocannabinol psychoactive effects. It is a resorcinol-based compound with a broad spectrum of potential therapeutic properties, including neuroprotective effects in numerous pathological conditions. CBD neuroprotection is due to its antioxidant and antiinflammatory activi-ties and the modulation of a large number of brain biological targets (receptors, channels) involved in the development and maintenance of neurodegenerative diseases...
