Sedative effects of the essential oil from the leaves of Lantana camara occurring in the Republic of Benin via inhalation in mice
AbstractLantana camara Linn. (Verbenaceae) is used traditionally for its numerous medicinal properties such as antimalarial, antibacterial, anticancer and anti-inflammatory. In the present study, we investigated the chemical composition of essential oil from the leaves ofL. camara (LCEO) occurring in the Republic of Benin (West Africa) in comparison with LCEOs from other regions; evaluated its sedative effects in mice via inhalation administration; and identified the compounds responsible for activity. LCEO was extracted by hydrodistillation and chemical analyses of the oil were performed by GC and GC/MS. The oil was dominated by monoterpene hydrocarbons (60.58%) and oxygenated monoterpenes (33.39%), among which sabinene (38.81%) and 1,8-cineole (28.90%) were the most abundant. LCEO administered via inhalation to mice significantly decreased locomotor activity in a dose-dependent manner, mainly at the doses of 0.0004 and 0.04 mg per 400 μL of triethyl citrate (TEC). The oil was fractionated to give two fractions, which were further investigated, and revealed that both sabinene and 1,8-cineole were the principal active compounds. The results of the present study indicated that via inhalation administration, LCEO and it s main constituents could be considered as promising candidates for the management of dementia, insomnia, attention deficit hyperactivity disorder and other central nervous system-associated diseases.Graphic abstract
DEMENTIA can be tricky to pick up on in the earliest stages. However, mounting research indicates a certain time of day when symptoms may be more noticeable. What time do you need to be on full alert?
CONCLUSIONS: Individually customized, multicomponent exercise programs lead to improved levels of cognitive function, depression, and quality of life, especially among those who are more frail. PMID: 33029968 [PubMed]
Conclusion: SLT induces relaxation of rat isolated tail artery through endothelium-independent mechanisms. The SLT-induced vasodilatation appeared to be jointly meditated by blockages of extracellular Ca2+ influx via receptor-gated and voltage-gated Ca2+ channels and inhibition of the release of Ca2+ from the sarcoplasmic reticulum.

In conclusion, in this database study of elderly patients coded with NAFLD no independent association with incident dementia was detected. Risk assessment regarding dementia in patients with NAFLD should be carried out in the same way as for metabolic burdened patients.

FRIDAY, Oct. 9, 2020 -- Patients with type 2 diabetes (T2D) are more likely to develop vascular dementia and nonvascular dementia compared with controls without diabetes, according to a study presented at the annual meeting of the European...
Conclusion: The ADE (adverse drug event) signal detection based on FAERS is helpful to clarify the potential adverse events related to ribavirin-interferon combination for novel coronavirus therapy; clinicians should pay attention to the adverse reactions of gastrointestinal and blood systems, closely monitor the fluctuations of the platelet count, and carry out necessary mental health interventions to avoid serious adverse events.

CONCLUSIONS: Findings provide a novel understanding of ARND prevalence in a previously understudied area, although the prevalence estimate is conservative and should be interpreted cautiously for reasons discussed. Findings also highlight an inconsistency between diagnoses presented in nosological systems (e.g., International Classification of Diseases-10th Revision) and those used in practice and therefore a need to evaluate novel diagnostic conceptualizations of alcohol-related neurocognitive impairment.

Conclusion Our case is the second to describe worsened choreoathetoid movements with fluoxetine and psychostimulants in HD, and the first with melatonin. These observations are objectified by our patient’s marked improvements in movement and handwriting assessments (Figure 1). We calculated Naranjo adverse event scores of 5, 5, and 2 for fluoxetine, lisdexamfetamine, and melatonin, respectively, based on several years of this individual’s outpatient medical records and current available literature (Table 1). Due to physiological and biochemical changes associated with HD progression, these medications co...
Conclusion Healthcare providers in general, and specifically those in the mental health and substance abuse fields, should keep in mind that nootropic use is an under recognized and evolving problem. Nootropic use should be considered in cases where there are sudden or unexplained exacerbations of psychiatric symptoms in patients who have been stable and medication adherent. It is also important to remember that most nootropics are not detected on standard drug toxicology screening tests. We have very little clinical information on how nootropics may interact with psychotropics (or other medications) and potentially cause ...
