TL;DR: La conclusion general es that el consumo of cafeina, hasta 300 mg/dia, no constituye un mayor riesgo of infarto al miocardio, of hipertension, o of modificacion of los niveles plasmaticos de indicadores of riesgos cardiovascular, como the proteina C reactiva y the homocisteina.
Abstract: La cafeina es el principal componente activo del cafe y los efectos del consumo de cafe se asocian mayoritariamente a la cafeina, una metilxantina que actua como antagonista de los receptores de adenina en el sistema nervioso. Son numerosos los efectos en la salud atribuidos a la cafeina, siendo algunos beneficos y otros deletereos: en la salud cardiovascular, diabetes tipo 2, tolerancia a la glucosa y sensibilidad a la insulina, en la cinosis hepatica y el carcinoma hepatocelular, entre otros efectos. Este articulo realiza una revision de dos aspectos de preocupacion en la salud publica relacionados con el consumo de cafe y la cafeina: su efecto en la salud cardiovascular y en la salud maternal (periodo perinatal). La conclusion general es que el consumo de cafeina, hasta 300 mg/dia, no constituye un mayor riesgo de infarto al miocardio, de hipertension, o de modificacion de los niveles plasmaticos de indicadores de riesgo cardiovascular, como la proteina C reactiva y la homocisteina. En relacion a la salud maternal, las conclusiones son similares, un consumo moderado de cafeina (300 mg/dia o menos) no constituye un riesgo de menor concepcion, de diabetes gestacional, de menor crecimiento fetal, o de defectos congenitos. La ausencia de riesgo, sin embargo, no constituye un estimulo al consumo de cafe durante el embarazo. Si el consumo de cafe por parte de la futura madre es moderado, puede considerarse la continuacion del consumo durante el embarazo bajo supervision medica

TL;DR: In this paper, the authors evaluated the potential in the extraction of biocomponents in the coffee processing process using two water samples (M1, M2) and found mesophiles, coliforms and staphylococci in both samples.
Abstract: espanolEn el procesamiento del cafe, solo se aprovecha el 5 % del producto fresco y se generan residuos como aguas mieles (AM), que pueden llegar hasta 40 L/Kg de cafe pergamino seco y al ser vertidas pueden provocar contaminacion de alto impacto ambiental. Consecuentemente, el objetivo fue caracterizar fisicoquimica y microbiologicamente dos muestras de AM (M1, M2) con el fin de evaluar el potencial en la extraccion de biocomponentes. Los parametros medidos a las dos muestras de agua fueron Demanda Quimica de Oxigeno (DQO), nitrogeno, amonio, cromo, oxigeno disuelto (OD), pH, conductividad, acidez volatil, fosforo, cloruros, solidos, color y, adicionalmente se cuantificaron mesofilos, coliformes totales y estafilococos. Se identificaron diferencias significativas entre las muestras y un efecto del procesamiento del cafe, sobre las caracteristicas evaluadas. M2 mostro mayor concentracion de OD, conductividad y cambio de color respecto al control, mientras que M1 tuvo mayor concentracion para los demas parametros evaluados. Cromo y amonio estuvieron por debajo del limite de deteccion de la prueba empleada, por el contrario, la DQO fue superior a lo reglamentado para aguas domesticas. En el analisis microbiologico, se encontraron mesofilos en ambas muestras, y M2 presento coliformes y estafilococos. Con lo anterior se evidencia que el metodo de procesamiento de cafe afecta los parametros de calidad de las aguas residuales y por ende se deben implementar metodologias de tratamiento y/o aprovechamiento acordes a las caracteristicas intrinsecas de cada proceso. EnglishIn the coffee processing, only 5 % of the fresh product is used and waste is generated as wastewater (WW), which can reach up to 40 L / Kg of dry parchment coffee and when spilled can cause pollution of high environmental impact. Consequently, the objective was to characterize physicochemical and microbiologically two WW samples (M1, M2) in order to evaluate the potential in the extraction of biocomponents. The parameters measured to the two water samples were Chemical Oxygen Demand (COD), nitrogen, ammonium, chromium, dissolved oxygen (DO), pH, conductivity, volatile acidity, phosphorus, chlorides, solids, color and, in addition, mesophiles, total coliforms and staphylococci were also quantified. Significant differences between the samples and an effect of coffee processing on the characteristics evaluated were identified. M2 showed a higher concentration of OD, conductivity and color change with respect to the control, while M1 had a higher concentration for the other parameters. Chromium and ammonium were below the detection limit of the test used, on the contrary, the COD was higher than what was regulated for domestic waters. In the microbiological analysis, mesophiles were found in both samples, and M2 presented coliforms and staphylococci. With the above it is evident that the coffee processing method affects the parameters of wastewater quality and therefore treatment and/or exploitation methodologies must be implemented according to the intrinsic characteristics of each process. portuguesNo processamento de cafe, apenas 5 % do produto fresco e utilizado e os residuos sao gerados como aguas residuais (AR), que pode chegar a 40 L / Kg de cafe em pergaminho seco e quando derramado pode causar poluicao de alto impacto ambiental.

Na analise microbiologica, mesofilos foram encontrados em ambas as amostras, e M2 apresentou coliformes e estafilococos. Com o exposto, e evidente que o metodo de processamento do cafe afeta os parâmetros da qualidade das aguas residuais e, portanto, as metodologias de tratamento e / ou exploracao devem ser implementadas de acordo com as caracteristicas intrinsecas de cada processo.

TL;DR: The objective of determining the incidence of phytohormone kinetin in the growth of four varieties of Arabica coffee, grafted on robust pattern, was executed in the nursery of the experimental farm of the Southern State University of Manabi.
Abstract: The project tends to achieve the production of higher plants, tolerant to pests and diseases; it was executed in the nursery of the experimental farm of the Southern State University of Manabi, located in the Andil site; with the objective of determining the incidence of phytohormone kinetin in the growth of four varieties of Arabica coffee: Sarchimor 1669, Sarchimor 4260, Pache and red Catuai, grafted on robust pattern. The applied methodology was experimental-factorial of A x B with random block designs with 8 treatments, one for each variety used with hormone and one for each variety without hormone and four repetitions; For the evaluation of the averages, the Tukey test was used at 95% confidence; the following variables were analyzed: height of plants, diameter of plants, length of leaves, number of leaves, leaf width, leaf area, root length, root volume, root weight and vigor of the plants, in a period of six months from January 20, 2017. The results of the arrest at 15 days after the grafting in the four varieties considered determined the following percentages: pache, 98.50%; Sarchimor 1669, 98.00%; Catuai red, 97.75% and Sarchimor 4260, 97.25%. Subsequently we proceeded to quantify the values of the variables based on which it was recommended to strengthen the results obtained by performing other tests of similar characteristics.

TL;DR: Inclusion of up to 10% coffee pulp in the diet of ewe lambs for 16 days prior to breeding improves oxidative status without causing adverse effects on pregnancy, estrus or prolificacy.
Abstract: Background: Coffee pulp has a high content of antioxidants capable of modifying the oxidative status in small ruminants. However, high amounts for a prolonged time can reduce fertility. Objective: To determine the effect of two inclusion levels of coffee pulp during estrous synchronization on reproductive variables and oxidative status of primiparous ewes. Methods: Sixty Suffolk x Dorset primiparous ewes were distributed into three treatments in a completely randomized design; T0: (n=20) 1.5 kg balanced diet, Tl: (n=20) 1.5 kg balanced diet and 5% coffee pulp, T2: (n=20) 1.5 kg balanced diet and 10% coffee pulp. Supplementation was given for 16 days before estrus synchronization and until the beginning of the breeding season. A progestogen (CIDR®) was inserted for ll days and a dose of PGF2a was applied two days prior to its withdrawal. Estrus detection started 12 hours after CIDR withdrawal. Blood samples were obtained during the supplementation period to measure oxidative status, antioxidant capacity, glucose and insulin, and up to 9 days after breeding to determine progesterone concentration. Pregnancy diagnosis was performed at 30 and 60 days post-breeding. An analysis of repeated measures of mixed effects and frequency analysis were carried out. Results: Inclusion of coffee pulp for a short period prior to breeding did not affect reproductive parameters, nor progesterone, glucose or insulin concentrations (p>0.05); however, antioxidant capacity increased, while lipid oxidation showed an opposite trend (p<0.05). Conclusion: Inclusion of up to 10% coffee pulp in the diet of ewe lambs for 16 days prior to breeding improves oxidative status without causing adverse effects on pregnancy, estrus or prolificacy.
