Seeds are a vital component of the world’s diet. Cereal grains alone, which comprise -90% of all cultivated seeds, contribute up to half of the global per capita energy intake. Not surprisingly then, seed biology is one of the most extensively researched areas in plant physiology. Even in relation to the topics reviewed here, a casual perusal of the Agricola database reveals that well over 5000...

BACKGROUND In 2 meta-analyses of randomized controlled trials, increased coffee intake was associated with slightly higher blood pressure. However, these trials were short in duration (<85 d). OBJECTIVE We conducted a systematic review and meta-analyses of long-term prospective studies that examined the association of habitual coffee consumption with risk of hypertension. DESIGN We searched...

European physicians treat benign prostatic hyperplasia (BPH) with saw palmetto extract (SPE), while American physicians generally disregard SPE because "research is lacking." The authors investigated this discrepancy with a literature search and a clinical trial. The literature search began with MEDLINE, then expanded to "alternative" databases, including AGRICOLA, EMBASE, IBIS, and Cochrane, p...

Definitions Abbreviation: A shortened form of a word, term or phrase used chiefly in writing to represent the full form (for example: 0 C for degree centigrade, N for nitrogen, ha for hectare, etc.) Acronym: More commonly used in writing and conversation, an acronym is formed by taking the initial letters of a name, term, or title (such as WO for Washington Office, NFS for National Forest Syste...

OBJECTIVES An increasing number of reports suggest that chemical and physical agents in the environment, introduced and spread by human activity, may affect male fertility in humans. This article aims at evaluating the impact of environmental exposures (pesticides, phthalates, PCBs, air pollution, trihalomethanes (THMs), mobile phones) on semen quality, by reviewing most recent published litera...

For (S; ) a measurable space, let C1 and C2 be convex, weak* closed sets of probability measures on . We show that if C1[C2 satis…es the Lyapunov property then there exists a set A 2 such that min 12C1 1(A) > max 22C2 2(A). We give applications to Maxmin Expected Utility and to the core of a lower probability. 1 Main result If 1 and 2 are two probability measures on a -algebra , then (by de…nit...

We design a laboratory experiment to investigate two-sided link formation in a setting where payo s are heterogeneous and depend on direct links only. Our link formation rule is decentralized and players can make link o ers and counter-o ers, as in a Beckerian marriage market. The game is designed in such a way that if participants play a myopic payo -maximizing best response, it leads to an un...
