Determining the permeability of different types of landscape matrices to animal movement is essential for conserving populations in fragmented landscapes. We evaluated the effects of habitat patch size and matrix type on diversity, isolation, and dispersal of ithomiine butterflies in forest fragments surrounded by coffee agroecosystems in the Colombian Andes. Because ithomiines prefer a shaded ...

Nicaraguan smallholder cooperative leaders working in partnership with a California-based small-scaleroasting company pioneered an alternative approach to confronting the post-1999 coffee crisis. They builtcoffee tasting laboratories and integrated grassroots organizing efforts to create a national smallholdercooperative association that dramatically improved the quality, consistenc...

Coffee roasting affects the taste, color, and aroma of coffee. The Maillard reaction, a major reaction during the roasting process, produces melanoidin, which affects the overall antioxidant capacity and anti-inflammatory effects of coffee. In this experiment, coffee roasting was divided into four degrees: Light, Medium, City, and French. To examine the in vivo antioxidant and anti-inflammatory...

Asian palm civet coffee or kopi luwak (Indonesian words for coffee and palm civet) is well known as the world's priciest and rarest coffee. To protect the authenticity of luwak coffee and protect consumer from luwak coffee adulteration, it is very important to develop a robust and simple method for determining the adulteration of luwak coffee. In this research, the use of UV-Visible spectra com...

Coffee is a commonly consumed beverage with potential health benefits. This review will focus on cardiovascular disease. There are three preparations of coffee that are commonly consumed and thus worthy of examination; boiled unfiltered coffee, filtered coffee, and decaffeinated coffee. Coffee has over a thousand chemicals, many formed during the roasting process. From a physiological point of ...

Kopi Luwak, an exotic Indonesian coffee, is made from coffee berries that have been eaten by the Asian palm civet ( Paradoxurus hermaphroditus ). Despite being known as the world's most expensive coffee, there is no reliable, standardized method for determining its authenticity. GC-MS-based multimarker profiling was employed to explore significant metabolites as discriminant markers for authent...

Coffee consumption has been shown to have adverse effects on various biological markers of coronary heart disease (CHD) risk, including serum cholesterol (1 ), blood pressure (2 ), insulin resistance (3 ), and plasma homocysteine (4 ). In contrast, higher coffee consumption has not been associated with a higher risk of CHD in prospective cohort studies (5–7 ). What could be the explanation for ...

OBJECTIVES To study prospectively the relation of coffee drinking with fatal and nonfatal coronary heart disease (CHD) and all-cause mortality and to perform a cross-sectional analysis at baseline on the association between coffee drinking and CHD risk factors, diagnosed diseases, self-reported symptoms, and use of medicines. METHODS The study cohort consisted of 20 179 randomly selected east...

Coffee is widely consumed, especially during mental stress conditions. Cardiovascular impact of coffee remains debated because the underlying mechanisms of action are complex. We reported previously differential cardiovascular stimulation of coffee at rest depending on habitual consumption. The present study was designed to evaluate the effects of coffee on cardiovascular response to mental str...

and Applied Immunology , which later resulted in the general rejection of chlorogenic acid’s role in allergic disease. It was not until 1978 that Lehrer et al. [5] reported on the extraction and analysis of coffee-bean allergens, demonstrating that coffee-bean allergens differ from the allergen of castor beans. This was followed by a number of important serological and clinical studies establis...
