Abstract This study aimed to analyze the phytochemical profile of essential oil obtained from the leaves of Coriandrum sativum L., and its antifungal activity against Candida spp. The research consisted of an in vitro study including collecting the vegetable product, analysis of its macronutrients, extraction, and chemical analysis of the essential oil, and assaying antifungal activity through minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC), with growth inhibition kinetics, and the product’s effects on multi-species Candida biofilm. Nitrogen (47.08 g Kg-1), phosphorus (5.3 g Kg-1) and potassium (50.46 g Kg-1) levels were within the normal range. The major constituents were octanal, decanal, dec-(2E)-enal, and dodecanal. The MIC and MFC of the product evaluated against 11 tested Candida strains ranged from 31.25 to 250 μg/mL. There was inhibition of fungal growth during 24 hours of exposure at the 3 concentrations tested (250, 125, and 62.5 μg/mL). The concentration of 80 mg/mL promoted the greatest reduction in multispecies biofilm (70% reduction in biofilm). Coriandrum sativum L. essential oil extract is principally constituted of alcohols and aldehydes and presents fungicidal activity against Candida spp. in its in planktonic and biofilm forms.

O extrato aquoso da casca do caule, na concentração de 10.000 µg/mL, inibiu o crescimento de Staphylococcus aureuscom halo de 20 mm. Já o extrato hidroalcoólico da casca do caule inibiu apenas S. aureuscom halo de 18 mm, enquanto o extrato da folha inibiu o crescimento de dois dermatófitos, Trichophyton mentagrophytese Microsporum canis. Por outro lado, o extrato hidroalcoólico da casca da raiz inibiu apenas M. caniscom halo de 15 mm de diâmetro. Das frações do extrato aquoso da folha, apenas acetato de etila inibiu o crescimento de Streptococcus epidermides, Candida albicans, T. metagrophytese M. canis.Para o extrato etanólico do caule, a fração aquosa inibiu S. epidermidese S. aureus.

The species Dioclea grandifloraMart. ex. Benth., Fabaceae is a plant that belongs to the Fabaceae family, popularly known as "mucunã-de-caroço" and "olho-de-boi". It can be found distributed in mountainous regions and in the scrub savanna of Brazil. The aqueous, ethanol and hydroalcoholic extracts of stem bark, root bark and leaves of D. grandifloraon concentration from 313 µg/mL to 10.000 µg/mL, were analyzed by the agar diffusion technique, front to twenty microorganisms, representatives of Gram-positive and Gram-negative bacteria, filamentous fungi and yeasts. The aqueous extract of stem bark, on concentration of 10.000 µg/mL, inhibited the growth of Staphylococcus aureuswith a 20 mm halo. Hydroalcoholic extract of stem bark only inhibited S. aureuswith a halo of 18 mm, while leaves extract inhibited the growth of two dermatophytes, Trichophyton mentagrophytes and Microsporum canis. On the other hand, hydroalcoholic extract of root bark only inhibited M. caniswith a halo of 15 mm diameter. From the fractions of aqueous extract of leaves, only ethyl acetate inhibited the growth of Streptococcus epidermides, Candida albicans, T. mentagrophytese M. canis. For the ethanol extract of stem bark, the aqueous fraction inhibited S. epidermides and S. aureus.

OBJECTIVE: Non-pituitary tumors have been reported in a subset of patients harboring germline mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene. However, no detailed investigations of non-pituitary tumors of AIP-mutated patients have been reported so far. PATIENTS: We examined a MEN1- and p53-negative mother-daughter pair with acromegaly due to somatotropinoma. Subsequently, the mother developed a large virilizing adrenocortical carcinoma and a grade II B-cell non-Hodgkin's lymphoma. DESIGN: Mutational analysis was performed by automated sequencing. Loss-of-heterozygosity (LOH) analysis was carried out by sequencing and microsatellite analysis. AIP expression was assessed through quantitative PCR (qPCR) and immunohistochemistry. RESULTS: The functional inactivating mutation c.241C>T (R81X), which blocks the AIP protein from interacting with phosphodiesterase 4A (PDE4A), was identified in the heterozygous state in the leukocyte DNA of both patients. Analyzing the tumoral DNA revealed that the AIP wild-type allele was lost in the daughter's somatotropinoma and the mother's adrenocortical carcinoma. Both tumors displayed low AIP protein expression levels. Low AIP gene expression was confirmed by qPCR in the adrenocortical carcinoma. No evidence of LOH was observed in the DNA sample from the mother's B-cell lymphoma, and this tumor displayed normal AIP immunostaining. CONCLUSIONS: Our study presents the first molecular analysis of non-pituitary tumors in AIP-mutated patients. The finding of AIP inactivation in the adrenocortical tumor suggests that further investigation of the potential role of this recently identified tumor suppressor gene in non-pituitary tumors, mainly in those tumors in which the cAMP and the 11q13 locus are implicated, is likely to be worthwhile.

INTRODUÇÃO: Pacientes com deficiência de hormônio de crescimento (GH) apresentam diversas alterações clínicas (ex: redução de massa muscular e de função cardíaca) e psíquicas (ex: quadros fóbicos, sintomas depressivos, déficits cognitivos). OBJETIVO: Avaliar o impacto da terapêutica com rh-GH em adultos com deficiência de GH. MÉTODO: Nove pacientes foram diagnosticados com deficiência de GH e então submetidos a ensaio clínico, duplo-cego, controlado, recebendo rh-GH (0,250UI/Kg/semana) ou placebo, por período de 6 meses. RESULTADOS: Houve melhora significativa (p<0,05) em parâmetros clínicos ( aumento de massa muscular, redução do índice de massa corpórea (BMI), aumento de gasto energético), psiquiátricos (sintomas depressivos avaliados pelas escalas de Beck e Hamilton (p= 0,043)) e neuropsicológicos (testes de atenção (p= 0,035), fluência verbal (FAS: p= 0,02), além da melhora de eficiência cognitiva (testes do WAIS-R: vocabulário (p= 0,027) , Arranjo de Figuras (p= 0,017), Compreensão (p= 0,01) ). CONCLUSÃO: Prejuízos clínicos, psíquicos e neuropsicológicos causados pela deficiência de GH em adultos podem ser reduzidos pela terapêutica com rh-GH.

BACKGROUND: Untreated GH-deficient adults have a diversity of dysfunctions (e.g. reduced muscle strength, emotional instability during stress, depressive symptoms) that may cause deleterious effects on quality of life, and may be positively influenced by recombinant human growth hormone (rh-GH) therapy. AIM: To evaluate the impact of a clinical intervention with rh-GH therapy on GH - deficient adults. METHOD: The physical, psychiatric and neuropsychological status of 9 GH-deficient adults was determined before and after the administration of rh-GH (0.250 IU/Kg/week) in a double blind placebo-controlled trial for six months. Patients then received rh-GH for a further period of 6 months and their status was re-evaluated. RESULTS: Rh-GH was significant better than placebo at 6th month (p<0.05), producing increased serum Insulin like growth factor-I (IGF-1) levels, reduced body mass index (BMI) and body fat, increased lean body mass and water, reduced waist/hip ratio and increased energy expenditure. The rh-GH therapy was also significantly better than placebo on depressive features as measured by the Hamilton Depression Scale (17-items) (p= 0.0431) and the Beck Depression Inventory (p= 0.0431). Neuropsychological evaluations showed significant improvements in measures of Attention: Digit Backward (p= 0.035),Verbal Fluency (FAS) (p= 0.02) and Cognitive Efficiency (WAIS-R tests): Vocabulary (p= 0.027) , Picture Arrangements (p= 0.017), and Comprehension (p= 0.01) following rh-GH therapy. CONCLUSION: The clinical, psychiatric, and neuropsychological impairments of untreated GH-deficient adults can be decreased by rh-GH therapy.
