RESUMEN

As one of notable works of HUANG Yuanyu, a renowned physician from the Qing Dynasty, The Indications of Classics by Four Medical Sage emphasize the theoretical paradigm of “one qi circulation” with a particular focus on the middle qi. Building upon disease differentiation and treatment, HUANG Yuanyu attaches great importance to understanding the underlying cause of the disease. It is believed that the imbalance of the six climatic factors is the fundamental cause of diseases. The concept of mutual interaction between the physiological and pathological aspects of the six climatic factors is proposed to grasp the basic pathogenesis. Based on the individual's specific condition of six climatic factors, excess or deficiency, specific prescriptions are formulated. The diagnosis and treatment system can be summarized as a “differentiation of diseases → disease etiology → differentiation of the condition of six climatic factors → individualized pathogenesis of traditional Chinese medicine (TCM) → prescription of TCM” model based on the holistic view. HUANG Yuanyu' s diagnosis and treatment system is highly practical and can provide reference for clinical diagnosis and treatment of diseases in TCM.

RESUMEN

Biofilm is recognized as one of the virulence factors of uropathogenic Escherichia coli. It offers bacteria significantly increased tolerance to antibiotics and makes difficulties in infection eradication. In this study, the biofilm formation ability of clinical isolates of uropathogenic E. coli as well as the antibiofilm activity of the common Garden sage, Salvia officinalis L. extracts were investigated in vitro. The influence of growth conditions (nutrient composition and incubation period) on biofilm formation of E. coli strains was evaluated using crystal violet staining procedure. The tested strains better formed biofilms after a longer incubation period (48 h). In addition, biofilm formation depended on nutrient medium composition. The eight strains were slime producers (Congo red agar assay). The water, ethanol, acetone and diethyl ether S. officinalis extracts were screened for their ability to inhibit the formation and metabolic activity of E. coli biofilms using crystal violet and resazurin assay, respectively. The water extract was not active, while ethanol, acetone and diethyl ether extract exhibited antibiofilm activity (MBIC= 2.5-10 mg/mL). The microscopic visualization of treated E. coli LM1 biofilm has shown morphological and density changes. In addition, the concentrations of phenolic compounds were determined spectrophotometrically. The highest content of total phenolics was found in acetone extract while the flavonoids in water extract

RESUMEN

Abstract: Tissue culture technique is one of the best methods to reproduce salvia plant Therefore, the aim of this research was to enhance the in-vitro callus proliferation and production of secondary metabolites of S. moorcroftiana using different combinations of auxin, cytokinin and melatonin. Initially, callus induction was optimized using indole acetic acid (IAA), 2, 4-dichlorophenoxy acetic acid (2,4-D), and naphthalene acetic acid (NAA) applied at different concentrations in combination with 1 mg L-1 of 6-benzylaminopurine (BAP). The results indicates that earliest days to callus induction (14.67 days) was occurred in the media fortified with 2, 4-D+BAP (2.0+1.0 mgL-1). Whereas the highest callus initiation (100%) was induced on MS medium incorporated with 2,4-D+BAP (1+1mgL-1). Furthermore, maximum fresh weight was obtained when 2,4- D + BAP at the rate of (1+ 1mg L-1) was incorporated and dry weight was attained when 2,4- D + BAP at the rate of (2+1 mg L-1) was added to MS media. The maximum fresh and dry weight was obtained when melatonin at rate of 1.5 mg L-1 was supplemented with MS media including 2,4-D + BAP (1+1mg L-1), moreover the maximum DPPH scavenging activity, total phenolic and flavonoid content was noted when supplemented with melatonin at rate of 1.5 mg L-1. In conclusion, among various concentrations of plant growth regulators, 2,4- D + BAP at the rate of (1+ 1mg L-1) along with 1.5 g L-1 melatonin was the best for callus growth and production of secondary metabolites of S. moorcroftiana.

RESUMEN

Traditionally, chimeric RNA is thought to be generated by chromosome rearrangement, and its products (RNAs and proteins) were once considered as unique features of cancer. However, with the advancement of next-generation sequencing technologies and the development of bioinformatics software tools, increasing numbers of chimeric RNAs are being identified from various RNA-Seq database. Recently, numerous chimeric RNAs were discovered in human normal tissues and cell lines, with physiological functions. Besides chromosome rearrangement, chimeric RNAs are formed by different molecular mechanisms, including trans-splicing, cis-splicing of adjacent genes. Chimeric RNAs, without chromosomal changes, are regulated at the transcriptional level, and they show specific physiological functions and regulation patterns. Their dysregulation may induce cell differentiation and tumorogenisis. In addition, chimeric RNAs also play roles in normal cell growth and/or migration, cell cycle and apoptosis, induce genomic aberration by influencing chromosome rearrangement, act as potential competitive endogenous RNA, and influence stem cell differentiation. The expression of chimeric RNAs in specific tissues and cell development stages has the potential to be used as diagnostic and therapeutic biomarkers. Histological mapping studies can improve the specificity of treatment for unique cell types, and the chimeric RNA provides a new perspective to achieve this goal. The widespread existence of chimeric RNAs suggests that they may extend the diversity of genomes in human and higher animals.

RESUMEN

Lettuce is susceptible to several diseases, especially soft rot caused by bacteria of the genus Pectobacterium. Due to the adaptability of this pathogen and the lack of disease control registered for the crop, the objective of this work was to evaluate the effects of essential oils in the management of soft rot caused by P. aroidearum in lettuce. The study was developed at the Universidade do Estado da Bahia, Juazeiro, BA, Brazil, and the essential oils (EOs) of orange, bergamot, lemongrass, palmarosa, citronella, cloves, tea tree, rosemary, sage, and ginger were used in concentrations of 0.25; 0.5; 0.75 and 1.0% to assess the in vitro growth inhibition of the bacterium. Subsequently, the curative effects of the disease were evaluated by applying the EOs that obtained the best results in vitro in lettuce plants of the susceptible variety "Mônica". The treatments were applied, via spraying, 12 hours after inoculation using the bite method with bacterial suspension. The best in vivo treatment was selected to assess its preventive and curative activity, as well as to find the ideal concentration for reducing epidemiological variables and chromatographic characterization. The EOs of palmarosa, sage, citronella, lemongrass, and cloves (0.25%), and that of sage (0.75%), inhibited bacterial growth in vitro. The EO of salvia showed the best results in vivo, inhibiting the growth of the disease in concentrations of 0.50 and 0.75%, so it was selected for the preventive and curative control tests alone. The preventive treatment was not efficient for the management of soft rot in lettuce, however, from the regression analysis, a concentration of 0.64% of the salvia EO was found as a potential for curative control of this bacteriosis, as it reduces the incidence and severity of the disease. Linalyl acetate and linalool were found in higher concentrations in the chromatographic analysis. These components, probably, conferred the bactericidal capacity of the EO of sage, being potential for the use in the control of P. aroidearum in lettuce.

RESUMEN

Backgraund: This study was designed to evaluate the phytochemical profile and the antimicrobial potential of the essential oil of Salvia brachyodon Vandas growing wild in Croatia. Short tooth sage (S. brachyodon Vandas),an endemic species that grows in the south east areas of the Adriatic coast in Croatia, Bosnia and Herzegovina, and Montenegro. It is a perennial plant that grows up to 70-80 cm in height and flowers from July to September. Methodology: The phytochemical components of the essential oil were identified by gas chromatography-mass spectrometry (GC-MS) analysis. The antimicrobial activity was assessed against a panel of representative Gram-positive and Gram-negative bacteria as well as fungi. The antimicrobial activities of the oil against pathogenic microorganisms were determined by using agar disc diffusion and broth microdilution methods. Results: From the thirty-eight identified constituents representing 95.7% of the oil, 1,8-cineole (16.7%), β-pinene (19.7%) and α-pinene (7.6%), were the major components. The levels of oxygenated monoterpenes such as camphor (5.6%), borneol (4.2%), myrtenol (2.4 %) and terpinen-4-ol were significant. Other important compounds were sesquiterpenes hydrocarbons β-caryophyllene (6.6%), α-humulene (4.9%), viridiflorol (3.0%), spathulenol (2.9%) and aromadendrene. Preliminary antimicrobial screening revealed that the oil exhibited a very interesting antimicrobial profile. The oil exhibited moderate in vitro antibacterial activity after it was tested against twenty pathogenic bacteria and fungal strains, but high antimicrobial activity observed against medically important pathogens such as E. coli O157:H7, Listeria monocytogenes and Candida albicans. Conclusion: Results presented here may suggest that the essential oil of S. brachyodon possess antimicrobial properties, and is, therefore, a potential source of antimicrobial ingredient in food and pharmaceutical industry. The obtained results are preliminary and a further research is needed in order to obtain information regarding the practical effectiveness of essential oil to prevent the growth of foodborne and spoilage microbes under specific application conditions.

RESUMEN

ABSTRACT Medicinal plants with essential oils in their composition havetypicallybeen shown to be promising in plant control. Sage (Salvia officinalis L.) is cited for its allelopathic effects. This study evaluated the allelopathic potential of dried sage leaves in vegetation, soil and the development of Lycopersicon esculentum Mill. (tomato), Panicum maximum Jacq. (guinea grass) and Salvia hispanica L. (chia) plants. Three seedlings were transplanted seven days after germination in 1 kg plastic containers with soil, in a greenhouse. The grinded dry mass of sage was placed at rates of 3.75; 7.5 15 t ha-1, and a control (no mass). After 30 days, the chlorophyll index of tomato and guinea grass plants were inhibited with 7.5 and 15 t ha-1 sage cover crops. Tomato shoot length was inhibited in all tested rates, and guinea grass plants showed some reduction in growth when using the highest rate of sage mass (15 t ha-1). The dry mass of tomato and guinea grass plants was reduced when using the15 t ha-1, and 7.5 and 15 t ha-1 of sage cover crops, respectively. It can be concluded that there was some effect of sage coverage on the soil in tomato and guinea grass, but no effect was observed on chia plants.


RESUMO As plantas medicinais que apresentam óleos essenciais em sua composição normalmente têm se mostrado promissoras no controle de plantas. A sálvia (Salvia officinalis L.) é citada por seus efeitos alelopáticos. Assim, esse estudo avaliou o potencial alelopático das folhas secas de sálvia na cobertura vegetal, no solo, sobre o desenvolvimento das plantas de Lycopersicon esculentum Mill. (tomate), Panicum maximum Jacq. (capim mombaça) e Salvia hispanica L. (chia). Três plântulas foram transplantadas, sete dias após germinação, em vasos plásticos de 1 kg, com terra, em casa de vegetação. Sobre elas foi disposta a massa seca triturada de sálvia nas proporções 3,75; 7,5 e 15 t ha-1, além da testemunha (sem massa). Após 30 dias, o teor de clorofila das plantas de tomate e capim mombaça foi inibido com 7,5 e 15 t ha-1 de sálvia em cobertura. O comprimento da parte aérea do tomate foi inibido em todas as proporções testadas e as plantas de capim mombaça apresentaram redução do crescimento quando se utilizou 15 t ha-1 de sálvia como cobertura. A massa seca das plantas de tomate e capim mombaça reduziu com o uso de 15 t ha-1 e, 7,5 e 15 t ha-1 de sálvia como cobertura, respectivamente.

RESUMEN

In the present research we investigated the anti-proliferative activity of Salvia menthifolia Ten. (formerly Salvia menthaefolia), Lamiaceae, on a glioblastoma cell line, since up to date poor therapeutic results have been reported for treatment of malignant glioblastoma. Methanol extracts from different anatomical parts of S. menthifolia were tested on DBTRG-05MG cell line by MTT assay. The most active primary stems extract was also evaluated for apoptosis induction. Results confirmed the anti-tumor property of all the organs and demonstrated that the primary stems extract induced apoptosis after 4 h with the highest values of DNA fragmentation after 6 to 24 h. Some extracts were also HPLC analyzed for polyphenols, althought activities could be due also to other constituents and to synergistic interactions. Rosmarinic acid, caffeic acid, luteolin-7-O-glucosyde and quercitrin were found in all the extracts. The good performance revealed for S. menthifolia towards this extremely aggressive human glioblastoma cell line confirms that the genus Salvia is a natural source of anti-tumor agents though there are great differences among the various species.

RESUMEN

La infección por el virus de inmunodeficiencia humana (VIH), adquirida a través de relaciones sexuales de riesgo, conlleva una importante morbilidad y mortalidad, sobre todo en personas jóvenes. Con una adecuada prevención, los adolescentes podrían determinar el futuro de la epidemia adoptando comportamientos sexuales responsables, por lo que nos propusimos caracterizar a los adolescentes e implementar una intervención educativa. Para esto, y de forma prospectiva, se encuestó a una muestra de 240 adolescentes de décimo grado del Instituto Preuniversitario Vocacional de Ciencias Exactas "Carlos Marx", de Matanzas, en el período 2008-2009. Se realizó un análisis estadístico mediante el programa Statcalc de Epiinfo y se compararon conocimientos y actitudes, antes y después de la intervención. Predominó el sexo femenino con edades entre 15 y 16 años. Poco más de la mitad de los estudiantes inició las relaciones sexuales a una edad media de 13,8 años, y de ellos, solo dos tercios utilizaron el condón de forma permanente. No conocían la diferencia entre sexo seguro y sexo protegido. Los medios de comunicación masiva fueron las principales fuentes de información. Tuvieron dificultades para diferenciar el portador del enfermo, así como el momento de realizar la prueba del VIH. La actitud hacia la enfermedad se valora de positiva y se demostró la influencia de pares para tomar decisiones. Se constató incremento de los conocimientos sobre el VIH, pero disonancia con el comportamiento sexual, lo que indica una necesaria continuidad en el trabajo educativo.


The infection by human immunodeficiency virus (HIV), acquired by risky sexual intercourses, entails a significant morbidity and mortality mainly in young people. With a proper prevention, adolescents could to determine the future of epidemics adopting responsible sexual behaviors, thus, authors to characterize adolescents and to apply an educational intervention. In a prospective way 240 adolescents from tenth degree from the "Carlos Marx" Exact Sciences Vocational Pre-university of Matanzas were polled from 2008 to 2009. A statistic examination was carried out by Epiinfo Statcalc program comparing the knowledges and attitudes before and after intervention. There was predominance of female sex with ages between 15 and 16 years. A few more than half of students started sexual intercourses at a mean age of 13,8 years and of them, only two thirds used condom in a permanent way. There was a lack of knowledge about the safe sex and protected sex. Media were the main sources of information. Had difficulties to differentiate the sick carrier as well as the moment to perform the HIV test. Attitude towards disease is assessed as positive demonstrating the influence of pairs to take decisions. There was an increase of knowledges on HIV, but a disagreement with the sexual behavior suggesting a necessary continuity in the educational work.

RESUMEN

Os óleos essenciais são alternativas ao uso de promotores de crescimento antibióticos na avicultura, devido à sua ação antimicrobiana, além de possuírem propriedades antioxidante e imunomoduladora. Este estudo foi realizado com o objetivo de avaliar o efeito da suplementação dietética de três doses de óleos essenciais (OLES) de orégano (Origanum vulgare L.), sálvia (Salvia officinalis L.), alecrim (Rosmarinus officinalis L.) e extrato de pimenta (Capsicum frutescens L.) em frangos de corte, pela análise do perfil eletroforético de soroproteínas e da peroxidação lipídica plasmática. Os animais (n=910) foram alocados de forma aleatória em cinco tratamentos, com sete repetições de 26 aves cada: o grupo controle (Tc), que recebeu dieta basal sem aditivos; o grupo que recebeu promotor de crescimento antibiótico na dieta (Tatb); e os grupos T50, T100 e T150, alimentados com OLES na doses de 50, 100 e 150mg kg-1, respectivamente. Aos 42 dias de idade, sete animais foram aleatoriamente selecionados (um de cada repetição) para o estudo do perfil eletroforético de soroproteínas e para a avaliação da peroxidação plasmática de lipídeos, pelo teste de formação de substâncias reativas ao ácido tiobarbitúrico (TBARS). Houve diminuição na concentração de globulinas totais no T150 e na fração betaglobulina nos grupos Tatb e T150 em relação ao grupo controle e ao T50 (P<0,05). Além disso, os níveis de TBARS plasmático foram menores nos grupos que receberam OLES em comparação ao Tc (P<0,05). Dessa forma, pode-se inferir que o efeito dos OLES, na maior dose administrada, sugere menor estímulo ao sistema inume humoral de frangos de corte, assim como acontece com a suplementação de promotores de crescimento antibióticos. Adicionalmente, ocorre menor peroxidação plasmática de lipídios e, consequentemente, menos dano oxidativo em frangos de corte, em resposta ao uso dos OLES.


Essential oils are an alternative to growth promoters based on antibiotics used in animal diets, due to its antimicrobial potential, and immunomodulatory properties. Serum proteins electrophoresis and plasma lipid peroxidation were evaluated in broilers fed with diets supplemented with antibiotics or essential oils from oregano (Origanum vulgare L.), sage (Salvia officinalis L.), rosemary (Rosmarinus officinalis L.) and pepper (Capsicum frutescens L.) crude extract (OLES). The animals (n=910) were distributed within five treatment groups and seven replicates containing 26 birds each one: control group (diet without additives); the group receiving an antibiotic growth promoter diet (Tatb); and the groups T50, T100 and T150 (supplemented with 50, 100 and 150mg kg-1 of OLES, respectively). After 42 days, seven animals were randomly selected for serum proteins electrophoretic fractionation and plasma lipid peroxidation evaluation by thiobarbituric acid reactive species (TBARS) test. Total globulins (T150), betaglobulin fraction (Tatb and T150) and plasma TBARS levels in the groups that received OLES (P<0.05) presented a decrease in relation to the control group. These results suggests lower stimulus to the humoral immune response at the higher dose of OLES, as occurred in the antibiotic growth promoter group. Moreover, it suggests lower lipid peroxidation and, consequently, lower oxidative damage caused by OLES use in broiler chickens.

RESUMEN

Methanolic extracts of eight Salvia species, namely S. aethiopis, S. candidissima, S. limbata, S. microstegia, S. nemorosa, S. pachystachys, S. verticillata, and S. virgata, sampled from Eastern Anatolia in Turkey, were screened for their possible antioxidant activities by two complementary test systems, namely DPPH free radical scavenging and b-carotene/linoleic acid. Total phenolic content of the extracts of Salvia species were performed Folin-Ciocalteu reagent and gallic acid used as standard. A wide variation has been observed among species in terms of antioxidant activity and total phenolic content. In both DPPH and b-carotene system, the most active plant was Salvia verticillata with a value of IC50=18.3 μg/ml and 75.8 percent, respectively. This specie also has the highest total phenolic content (167.1 mgGAE/g DW). The total amount of phenolics was between 50.3 to 167.1 mg GAE/g DW among species. A positive linear correlation was observed between total phenolic content and antioxidant activity of the extracts. The results suggest that the extract of Salvia species, notably Salvia verticillata with the highest antioxidant activity, can be used as natural antioxidants in the food industry.
