Abstract
BACKGROUND Cannabinoid-based therapy has been shown to be promising and is emerging as crucial for the treatment of cognitive deficits, mental illnesses, and many diseases considered incurable. There is a need to find an appropriate therapy for Alzheimer's disease, and cannabinoid-based therapy appears to be a feasible possibility. CASE PRESENTATION This report addresses the beneficial effect of cannabinoids in microdoses on improving memory and brain functions of a patient with mild-stage Alzheimer's disease. The patient is a 75-year-old white man presenting with main symptoms of memory deficit, spatial and temporal disorientation, and limited daily activity. The experimental therapeutic intervention was carried out for 22 months with microdoses of a cannabis extract containing cannabinoids. Clinical evaluations using Mini-Mental State Examination and Alzheimer's Disease Assessment Scale-Cognitive Subscale were performed. CONCLUSIONS Here we provide original evidence that cannabinoid microdosing could be effective as an Alzheimer's disease treatment while preventing major side effects. This is an important step toward dissociating cannabinoids' health-improving effects from potential narcotic-related limitations.

Abstract
RATIONALE Aporphine alkaloids represent a large group of isoquinoline natural products with important roles in biological and biomedical areas. Their characterization by electrospray ionization tandem mass spectrometry (ESI-MS/MS) can contribute to their rapid identification in complex biological matrices. METHODS We report the fragmentation of protonated 7,7-dimethylaporphine alkaloids by ESI-MS/MS, and the putative annotation of aporphine alkaloids in plant extracts. We used low- and high-resolution MS/MS analyses to rationalize the fragmentation pathways, and employed the B3LYP/6-31 + G(d,p) density functional theory (DFT) model to provide thermochemical parameters and to obtain the reactive sites. RESULTS DFT calculations of a set of 7,7-dimethylaporphine alkaloids suggested the heterocyclic amino group as the most basic site due to the proton affinity of the nitrogen atom. Collision-induced dissociation experiments promoted • OCH3 elimination instead of the expected neutral loss of the heterocyclic amino group, pointing to the [M - 15 + H]•+ ion as the diagnostic fragment for 7,7-dimethylaporphine alkaloids. The analysis of plant extracts led to the annotation of 25 aporphine alkaloids. Their fragmentation initiated with the loss of the amino group followed by formation of a cyclic carbocation. Further reactions derived from consecutive charge-remote and/or charge-induced fragmentations of the substituents attached to the aromatic system. The mechanisms were re-examined based on plausible gas-phase ion chemistry reactions. CONCLUSIONS Taken together, the diagnostic product ions and the series of radical and neutral eliminations provided information about the location of methylenedioxy, aromatic methoxy, and vicinal methoxy and hydroxy groups in aporphine alkaloids, assisting their characterization via MS/MS.

Abstract
The present study aimed to analyze the chemical composition of five species of the genus Piper (P. aduncum L.; P. crassinervium Kunth.; P. malacophyllum Prels.; P. gaudichaudianum Kunth.; P. marginatum L.), and assess their toxicity to the adults of Drosophila suzukii (Diptera: Drosophilidae) and the pupal parasitoid Trichopria anastrephae Lima (Hymenoptera: Diapriidae). The major compounds were monoterpene hydrocarbons (5.3-60.9%); oxygenated monoterpenes (13.3%); sesquiterpenes hydrocarbons (8.3-45.3%), oxygenated sesquiterpenes (5.2-58.8%); and arylpropanoids (15.2-29.6%). In bioassays of ingestion and topical application, essential oils (EOs) from P. aduncum, P. gaudichaudianum, and P. marginatum killed approximately 100% of adults of D. suzukii, similarly to the insecticide based on spinetoram (75 mg L-1) (96.2% of mortality). Besides, the dry residues from P. aduncum, P. gaudichaudianum, and P. marginatum provided a repellent effect on oviposition (≅ 7 eggs/fruits) and negative effects on egg viability (≅ 2 larvae/fruits) of D. suzukii on artificial fruits. Based on the estimate of the lethal concentration required to kill 90% of exposed flies, EOs from P. aduncum, P. crassinervium, P. gaudichaudianum, P. malacophyllum, and P. marginatum provided low toxicity to the parasitoid T. anastrephae in a bioassay of ingestion and topical application (mortality < 20%), similarly to the water treatment (≅ 5% of mortality). EOs of Piper species tested in this work showed to be promising plant insecticides for the management of D. suzukii.

Abstract
This is the first time that composition, antimicrobial potential and antioxidant ability of essential oil from the leaves of Baccharis oreophila are reported. Essential oil was obtained by hydrodistillation and analyzed by GC/MS. Antimicrobial potential was evaluated by diffusion disk and broth microdilution methods. ABTS.+ , DPPH. and FRAP methods were employed for antioxidant activity evaluation. Essential oil yield was 0.47 %. Sixty-five compounds were identified, representing 88.53 % of the total essential oil, which showed to be rich in oxygenated (37.88 %) and hydrocarbons sesquiterpenes (34.84 %). The main constituents were khusimone (16.37 %) and spathulenol (16.12 %). Antimicrobial activity was verified against S. aureus (10.33±0.5 mm, MIC: 1250 μg mL-1 ) and C. albicans (8.66±0.5 mm, MIC: >2500 μg mL.1 ). Antioxidant ability was evidenced by FRAP (4.09 μmol FeSO4 E mL-1 ), ABTS.+ (1.45 μmol TE mL-1 ) and DPPH. (1.04 μmol TE mL-1 ) scavenging capacity. Results showed that this essential oil has interesting biological potential, encouraging further investigations especially in relation to action mechanisms of antimicrobial and antioxidant activity.
