Abstract
Passiflora cincinnata Mast. is described as a native Caatinga species, used by nutritional and medicinal purposes, although there are still few studies and pharmacological data related to this species. This paper aims to evaluate the safety profile and hypolipidemic potential of the fruit peel of this species in mice. It was analyzed the chemical composition of ethanolic extract (EtOH-Pc) by HPLC-DAD-MS/MS, and the organic and inorganic composition of flour (MF-Pc). Also were evaluated the acute toxicity, the lipid-lowering potential of these samples, through of a pretreatment (oral: 100 and 200 mg/kg), and a single treatment with the same doses, after hyperlipidemic induction with triton WR-1339, using as animal model Swiss Mus musculus mice, besides histopathological analysis. The presence of flavonoids in the extract was confirmed, mainly C-glycosides, and antioxidant minerals and pectin, in flour. No clinical signs of toxicity or death were reported in the study. In the hyperlipidemia study model used, the analyzed substances, at all doses, notably decreased the lipid levels of TC, TG, LDL-c and VLDL-c and increase the HDL-c levels in the induced hyperlipidemic mice (p < 0.05). The results of the histopathological analysis showed that in the group only induced was identified the discrete presence of hepatic steatosis, in 2 animals at the analysis of 24 h, not being visualized in the groups treated with the substances evaluated. The results obtained in the present study suggest a hypolipidemic potential of the extract and flour, obtained from the fruit peel of Passiflora cincinnata Mast.

Abstract
Resumo O presente estudo refere-se ao impacto do uso de agrotóxicos sobre a saúde humana no Submédio do Vale do São Francisco. Por meio de entrevistas objetivou-se analisar a influência dos condicionantes sociais, culturais e econômicos no processo saúde-doença dos trabalhadores expostos a agrotóxicos. Para a coleta de dados foram entrevistados 339 trabalhadores rurais de perímetros irrigados dos municípios de Juazeiro-BA e Petrolina-PE. Todos do sexo masculino, sendo 182 (53,7%) proprietários rurais e 157 (46,3%) empregados, predominando indivíduos entre 40 e 59 anos entre os proprietários e abaixo de 39 anos entre os trabalhadores. Mais de 50% apresentou baixo nível de escolaridade e 55,2% tinha rendimentos mensais menor ou igual a 2 salários mínimos. Muitos sabem da importância do uso de EPIs e da obrigatoriedade do receituário agronômico para a utilização e a compra de agrotóxicos, entretanto cerca de 40% não usam EPIs ou fazem uso de forma incompleta e 28,9% não apresentam receituário durante a compra. Mais de 9% dos participantes relataram casos de intoxicação, no entanto, menos de 7% procuraram atendimento especializado. Os trabalhadores sabem que o uso de agrotóxicos nas lavouras os expõem a situações de risco, mas essa informação não é suficiente para alterar a conduta no exercício laboral.

Abstract
Inflammatory diseases result from the body's response to tissue damage, and if the resolution is not adequate or the stimulus persists, there will be progression from acute inflammation to chronic inflammation, leading to the development of cancer and neurodegenerative and autoimmune diseases. Due to the complexity of events that occur in inflammation associated with the adverse effects of drugs used in clinical practice, it is necessary to search for new biologically active compounds with anti-inflammatory activity. Among natural products, essential oils (EOs) present promising results in preclinical studies, with action in the main mechanisms involved in the pathology of inflammation. The present systematic review summarizes the pharmacological effects of EOs and their compounds in in vitro and in vivo models for inflammation. The research was conducted in the following databases: PubMed, Scopus, BIREME, Scielo, Open Grey, and Science Direct. Based on the inclusion criteria, 30 articles were selected and discussed in this review. The studies listed revealed a potential activity of EOs and their compounds for the treatment of inflammatory diseases, especially in chronic inflammatory conditions, with the main mechanism involving reduction of reactive oxygen and nitrogen species associated with an elevation of antioxidant enzymes as well as the reduction of the nuclear factor kappa B (NF-κB), reducing the expression of proinflammatory cytokines. Thus, this review suggests that EOs and their major compounds are promising tools for the treatment of chronic inflammation.

Abstract
BACKGROUND Passiflora cincinnata Mast. is described as a native species from the Caatinga biome, and used by traditional medicine for several pharmacological purposes, such as inflammatory disorders. However, studies that prove its biological activities are scarce. HYPOTHESIS/PURPOSE This paper aims to evaluate the antinociceptive and anti-inflammatory activities of the aerial parts of Passiflora cincinnata (Pc-EtOH) in mice. METHODS The chemical composition of Pc-EtOH was assessed by high-performance liquid chromatography coupled to diode array detector (HPLC-DAD). The antinociceptive profile of the extract (given orally: 100, 200 and 400 mg/kg) was established using the in vivo chemical models (acetic acid-induced abdominal constriction and formalin-induced paw licking test) and thermal (hot plate test) of nociception. The role of opioid, potassium channels, TRPV-1, muscarinic, serotoninergic (5-HT3) receptors and the participation of the nitric oxide pathway also was determined. The rota-rod test was used to verify the possible interference of the extract treatment in motor performance. Paw edema induced by carrageenan or histamine, and leukocyte migration, determination of total protein and nitric oxide to the peritoneal cavity were used for anti-inflammatory profile. RESULTS The presence of flavonoids in the extract was confirmed using HPLC-DAD. At all doses tested the Pc-EtOH significantly reduced the number of writhing and decreased the paw licking time in both phases of the formalin test (p < 0.05). In the hot plate test, the extract increased the reaction time, reducing painful behavior. The antinociceptive mechanism probably involves central and peripheral pathways, involving the pathway of opioid and muscarinic receptors with influence of potassium channels and the nitric oxide pathway. However, the motor coordination test indicated that in the time of 120 min the extract decreases the stay time of the animal in the rota-rod. Pc-EtOH inhibited significantly (p < 0.05) the increase of the edema volume after administration of carrageenan and histamine. In the peritonitis test, acute pre-treatment with Pc-EtOH inhibited leukocyte migration, with a reduction in the number of neutrophils and concentration of total proteins and nitric oxide. CONCLUSION The present study suggests that Pc-EtOH possesses peripheral and central antinociceptive action, and showed potential in inhibition of release of mediators of the inflammatory process.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Croton conduplicatus Kunth (Euphorbiaceae) is a Brazilian aromatic medicinal plant, widely known as "quebra-faca". In folk medicine, its leaves and stem-barks are used as a natural analgesic for the treatment of headaches. AIM OF THE STUDY In this study, we describe for the first time the neuropharmacological potential of the essential oil obtained from the leaves of Croton conduplicatus (EO) in experimental models of pain, anxiety and insomnia. The mechanisms of action involved in these activities were also investigated. MATERIAL AND METHODS Different experimental models were used to evaluate the antinociceptive (acetic acid, formalin-induced nociception and hot plate tests), anxiolytic (elevated plus maze and hole board tests) and sedative (thiopental-induced sleeping time) effects of EO in mice. EO was evaluated in three different doses (25, 50 and 100 mg/kg, i.p.) and compared with positive and negative controls in all experimental protocols. When appropriate, animals were pretreated with pharmacological antagonists (naloxone, atropine and flumazenil) in order to evaluate the mechanisms of action involved. A docking study also was performed to identify possible targets involved. RESULTS EO (25, 50 and 100 mg/kg, i.p.) demonstrated a significant antinociceptive activity in all experimental models. Pretreatment with naloxone or atropine reversed the antinociceptive response (p < 0.05), suggesting the involvement of opioid and muscarinic receptors, respectively. A docking study was performed with the major components identified in EO (1,8 cineole - 21.42%, spathulenol - 15.47%, p-cymene - 12.41% and caryophyllene oxide - 12.15%), demonstrating favorable interaction profile with different subtypes of muscarinic (M2, M3 and M4) and opioids (delta and mu) receptors. EO also showed anxiolytic (mainly at doses of 25 and 50 mg/kg, i.p.) and sedative (only at the dose of 100 mg/kg, i.p.) effects in mice. These pharmacological responses were reversed by flumazenil (p < 0.05), indicating possible involvement of GABAA receptors. CONCLUSION Our findings support the traditional use of this plant as a natural analgesic and suggest that EO is a multi-target natural product, presenting not only antinociceptive effect but also anxiolytic and sedative activities depending on the dose used.

Abstract
INTRODUCTION Depression is a serious mood disorder and is one of the most common mental illnesses. Despite the availability of several classes of antidepressants, a substantial percentage of patients are unresponsive to these drugs, which have a slow onset of action in addition to producing undesirable side effects. Some scientific evidence suggests that cyclodextrins (CDs) can improve the physicochemical and pharmacological profile of antidepressant drugs (ADDs). The purpose of this paper is to disclose current data technology prospects involving antidepressant drugs and cyclodextrins. AREAS COVERED We conducted a patent review to evaluate the antidepressive activity of the compounds complexed in CDs, and we analyzed whether these complexes improved their physicochemical properties and pharmacological action. The present review used 8 specialized patent databases for patent research, using the term 'cyclodextrin' combined with 'antidepressive agents' and its related terms. We found 608 patents. In the end, considering the inclusion criteria, 27 patents reporting the benefits of complexation of ADDs with CDs were included. EXPERT OPINION The use of CDs can be considered an important tool for the optimization of physicochemical and pharmacological properties of ADDs, such as stability, solubility and bioavailability.
