Effect of ghrelin on gonadotrophin secretion in women during the menstrual cycle
(2009)It has been suggested that ghrelin may affect reproduction in animals by decreasing pituitary LH secretion. The role of ghrelin on LH secretion in women has not been investigated. Our aim was to assess the effect of ghrelin ... -
Effect of prolonged aflatoxin B-1 administration on blood serum oestradiol-17 beta and progesterone concentrations of goats during the anoestrus period
(2015)The effect of prolonged aflatoxin B-1 (AFB(1)) administration on blood serum oestradiol-17 beta and progesterone concentrations in goats during the anoestrus period was investigated. Thirty Greek indigenous goats were used; ... -
Exceptional Longevity in the Tephritid, Ceratitis rosa, a Close Relative of the Mediterranean Fruit Fly
(2012)This study shows that the fruit fly, Ceratitis rosa (Karsch), has a significantly longer life span than the medfly, C. capitata (Wiedemann); the species used as a model organism for the demographics of insect aging. This ... -
Inhibitory Effect of Submaximal Doses of Ghrelin on Gonadotropin Secretion in Women
(2014)The effect of ghrelin on gonadotropin secretion has been equivocal. Recent data have shown an inhibitory effect of repeated injections of ghrelin on nocturnal LH and FSH secretion in women. The aim of this study was to ... -
Isozyme, protein, and RAPD markers within a half-sib family of buffelgrass segregating for apospory
(1996)Isolation of genes controlling apomixis would be useful to plant breeders for fixing hybrid vigor. A single gene codes for aposporous apomixis in buffelgrass [Pennisetum ciliare (L.) Link]. This study was undertaken to ... -
Oestradiol plus progesterone treatment increases serum leptin concentrations in normal women
(2001)BACKGROUND: Previous studies have alluded to a role for both oestradiol and progesterone in the secretion of leptin from fat cells in the human, although direct evidence has yet to be obtained. The study aim was to assess ... -
Ovarian allometry and the use of the gonosomatic index: a case study in the Mediterranean sardine, Sardina pilchardus
(2004)The gonosomatic or gonadosomatic index [GSI =( ovary weight/fish weight) x 100] has been widely used in. sheries science and experimental reproductive studies as a simple, low-cost measure of reproductive condition. However, ... -
Performance of the tobacco aphid Myzus persicae (Hemiptera : Aphididae) on Oriental and Virginia tobacco varieties
(2003)1 The life parameters of one red and one green clone of Myzus persicae reared on 11 Oriental tobacco type varieties (KP7, K63, KZ10/z, MA13/b, BX2/a, N34/4, KP14/a, Kolindros, S79, TA21 and BX81) and on five Virginia ones ... -
Response of local and commercial tomato cultivars and rootstocks to Meloidogyne javanica infestation
(2011)Fifty two local Greek tomato (Solanum lycopersicum) cultivars and accessions and ten commercial nematode-resistant tomato cultivars and rootstocks were evaluated under controlled environmental conditions for resistance ... -
Size-related habitat use, aggregation patterns and abundance of anglerfish (Lophius budegassa) in the Mediterranean Sea determined by generalized additive modelling
(2003)Spatial distribution patterns of black anglerfish, Lophius budegassa were examined in relation to size category bathymetry, locational covariates, and season. Data were collected during a 2-y period (1998-1999) of ... -
Social interactions regulate resource utilization in a Tephritidae fruit fly
(2009)Previous studies have suggested that social interactions (e.g., the actions and reactions elicited by the interaction of co-specific individuals) induce individual fruit flies (Tephritidae) to ingest more food, especially ... -
Sperm DNA fragmentation measured by Halosperm does not impact on embryo quality and ongoing pregnancy rates in IVF/ICSI treatments
(2015)Sperm DNA fragmentation (SDF) has been proposed to be one of the main markers regarding male infertility. A prospective study was performed to assess primarily whether sperm DNA damage has any impact on embryological data ... -
Supplementation of lactating ewes with a glucogenic preparation or beta-carotene in mid- to late lactation on subsequent milk yield and luteinizing hormone secretion
(2007)The effects of a glucogenic preparation (Nutrimix((R))) or beta-carotene (Rovimix((R)) beta carotene) supplementation of ewes during mid- to late-lactation on their milk yield were assessed in a study where 66 Chios-breed ... -
USE OF PRUSSIAN CARP, CARASSIUS GIBELIO, PITUITARIES IN THE ARTIFICIAL PROPAGATION OF FEMALE COMMON CARP, CYPRINUS CARPIO
(2008)Background. The usage of common carp pituitaries has been associated with very high costs, resulting from sacrificing the valuable broodstock. A close taxonomic proximity between the Common carps Cyprinus carpio L. and ...
