Evaluation of hops essential oil cytotoxicity and anti-cryptosporidium activity
Background. Hops essential oil (HEO) is a by-product of the brewing industry with proven antibacterial and antifungal activities. Its antiparasitic activity, however, has not been explored extensively. We sought to evaluate the ability of HEO and myrcene, a monoterpene predominantly present in HEO, …

Hops Production in Virginia: Nutrition, Fungal Pathogens, and Cultivar Trials
In the United States, hops (Humulus lupulus L.) are grown mainly in the Pacific Northwest (PNW). For this reason, most cultural information is based on the growing conditions of the PNW. Growing conditions in Virginia differ drastically and present unique disease and production challenges. Three …

A preliminary investigation of the chemistry of hops: Methods for extraction and alpha-acid isomerization kinetics
<p>Humulus lupulus, a climbing perennial vine, is grown and used extensively in the brewing industry as a natural preservative and to impart the bitter flavor and aroma typically found in beer. The flowering cones of the female H. lupulus plant are of particular importance as they contain the main …

Flavor Chemistry of Regional Hops (Humulus lupulus L.) and Novel Aroma Application of Hop-derived Products
… of understanding on aroma chemistry of regional hops limited their prosperity. Moreover, suitable postharvest drying and packaging practices for VA hop producers are not available. This dissertation aims to address above issues by investigating the aroma chemistry of VA hops by varieties …

Activation of proestrogens from hops by human intestinal bacteria: conversion of isoxanthohumol into the potent phytoestrogen 8-prenylnaringenin
Hop, an essential ingredient in beer, contains different prenylflavonoids, among which 8-prenylnaringenin (8-PN) would be the most potent phytoestrogen currently known. Therefore, hop extracts are now marketed to relief menopausal complaints but efficiency varies greatly among individuals. As …

Investigation of the hops α-acids isomerization and occurring losses of iso-α-acids during wort preparation in the brewhouse
… in order to avoid using an unnecessary amount of hops and thus to save raw material. The aim of the present dissertation is to clarify these factors in their combinatorial effect with regard to wort composition as well as wort treatment and to identify the substance, which binds hop bitter acids, …

Analysis of the United States Hop Market
<p>Hops are one of the four main ingredients used to produce beer. Many studies have been done to analyze the science behind growing and harvesting hops, creating hop hybrids, and how to brew beer with hops. However, there has been little research done revolving around the economic demand and …

Ground Reaction Force Analysis of the Anterior and Cross-Over Single Leg Hop Tests
… hop tests are commonly begun with anterior hops for distance and time, and then gradually move to cross-over hops for distance and time using a 15 cm cross-over. It is thought that the 15 cm cross-over hop is an optimal distance to stimulate excess forces on the lower extremity when compared …

Characterization Of A Novel Interactor/substrate For The Pro-apoptotic Serine Protease Omi/htra2
… This screening identified a novel protein (HOPS), as a specific interactor of Omi. The predicted amino acid sequence of this protein does not provide any information about its potential function in mammalian cells. However, experiments show that HOPS is cleaved in vitro by Omi. Furthermore, …
