A Survey in Hawaii for Parasitoids of Citrus Whiteflies (Hemiptera: Aleyrodidae), for Introduction into Greece.

Whitefly species of (Quaintance) and Ashby (Hemiptera: Aleyrodidae) are serious pests of citrus and other important fruit crops. The problem of citrus has initiated the successful introduction of several natural enemies for biocontrol programs in Hawaii and many other countries. Here, we summarized the history of infestation and biocontrol efforts of the two whiteflies in Hawaii for possible parasitoid importation into Greece.

Plant viruses induce plant volatiles that are detected by aphid parasitoids.

Aphis gossypii (Sternorrhyncha: Aphididae) aphids are vectors of important plant viruses among which cucumber mosaic virus (CMV) and potato virus Y (PVY). Virus-infected plants attract aphid vectors and affect their behavior and growth performance either positively or negatively depending on mode of transmission. Viruses cause changes in the composition and the amount of volatile organic compounds (VOCs) released by the plant that attract aphids.

Electrophysiological responses of Philaenus spumarius and Neophilaenus campestris females to plant volatiles.

The spittlebugs Philaenus spumarius and Neophilaenus campestris (Hemiptera: Aphrophoridae) are xylem-feeder insects that have been identified as vectors of Xylella fastidiosa in Europe. In the present study, we aim to identify volatile organic compounds (VOCs) that may act as semiochemicals for these species. Using the dynamic headspace technique, we collected VOCs from Olea europaea L.

Susceptibility of different developmental stages of parasitoids to insecticides commonly used in the Mediterranean olive agroecosystem.

Insecticide application and augmentative parasitoid releases are often considered incompatible. However, pesticide applications and parasitoid releases can be integrated into a pest management scheme if there is careful time scheduling of these interventions. In this study, we assessed the influence of commonly used insecticides (chlorpyrifos-methyl, deltamethrin, pyriproxyfen, thiamethoxam) in olive agroecosystems to two currently present Trichogramma parasitoids in the Mediterranean basin.

Oviposition-Induced Volatiles Affect Electrophysiological and Behavioral Responses of Egg Parasitoids.

In response to an attack by herbivores, plants emit a variety of compounds that may act as semiochemicals. Oviposition-induced volatiles (OIPVs) have been shown to mediate interactions between plants and natural enemies. Here, we investigated the role of OIPVs by towards two egg parasitoids, and .

Data on the scale insect (Hemiptera: Coccomorpha) fauna of Greece, with description of two new species.

Surveys of the scale insect (Hemiptera: Coccomorpha) fauna of Greece were carried out in 2013 and 2014. Altogether 93 scale insect species were collected, belonging to 11 families. Thirty-eight species (41%) proved to be new to the Greek fauna, including two species new to science (Anophococcus hellenicus Kaydan & Szita sp.

Myomas and Adenomyosis: Impact on Reproductive Outcome.

Among uterine structural abnormalities, myomas and adenomyosis represent two distinct, though frequently coexistent entities, with a remarkable prevalence in women of reproductive age. Various mechanisms have been proposed to explain the impact of each of them on reproductive outcome. In respect to myomas, current evidence implies that submucosal ones have an adverse effect on conception and early pregnancy.

Effect of male mating history and age on remating by female European corn borer.

If mating with an inferior male has high fitness costs, females may try to avoid mating with these males. Alternatively, females may accept an inferior male to ensure they have obtained at least one mate, and/or to avoid the costs of resisting these males. We hypothesized that females compensate for mating with an inferior male by remating.

Addition of low-dose hCG to rFSH during ovarian stimulation for IVF/ICSI: is it beneficial?

Purpose: The aim of the study was to assess the eftect ot the addition or iow-cose numan cnononic gonauoiropm (hCG) to ovarian stimulation with recombinant follicle stimulating hormone (rFSH) on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcome.

Materials And Methods: This retrospective clinical study was conducted on 141 women undergoing ICSI through a short GnRH-agonist protocol with rFSH and the addition of low-dose (100 IU/day) hCG. The control group consisted of 124 women undergoing ovarian stimulation with a similar protocol devoid of hCG.

Microarray Analyses Reveal Marked Differences in Growth Factor and Receptor Expression Between 8-Cell Human Embryos and Pluripotent Stem Cells.

Previous microarray analyses of RNAs from 8-cell (8C) human embryos revealed a lack of cell cycle checkpoints and overexpression of core circadian oscillators and cell cycle drivers relative to pluripotent human stem cells [human embryonic stem cells/induced pluripotent stem (hES/iPS)] and fibroblasts, suggesting growth factor independence during early cleavage stages. To explore this possibility, we queried our combined microarray database for expression of 487 growth factors and receptors. Fifty-one gene elements were overdetected on the 8C arrays relative to hES/iPS cells, including 14 detected at least 80-fold higher, which annotated to multiple pathways: six cytokine family (CSF1R, IL2RG, IL3RA, IL4, IL17B, IL23R), four transforming growth factor beta (TGFB) family (BMP6, BMP15, GDF9, ENG), one fibroblast growth factor (FGF) family [FGF14(FH4)], one epidermal growth factor member (GAB1), plus CD36, and CLEC10A.

Sublethal effects of the insecticidal fusion protein ω-ACTX-Hv1a/GNA on the parasitoid Eulophus pennicornis via its host Lacanobia oleracea.

Background: The neurotoxin peptide ω-ACTX-Hv1a, fused to the carrier molecule GNA, presents potential for insect control as a biopesticide, being orally toxic to insect pests from different orders. However, thorough evaluation is required to assure its safety towards non-target invertebrates. Effects of this novel biopesticide on the parasitoid Eulophus pennicornis via its host Lacanobia oleracea are presented.

Single nucleotide polymorphisms in the Anti-Müllerian hormone (AMH Ile(49)Ser) and Anti-Müllerian hormone type II receptor (AMHRII -482 A>G) as genetic markers in assisted reproduction technology.

Purpose: The aim of the study was to evaluate whether the presence Antimullerian hormone (AMH) and Antimullerian hormone type II receptor (AMHRII) single nucleotide polymorphisms (SNPs) Ile(49)Ser and -482A>G respectively are related to the assisted reproduction outcome.

Methods: A prospective cross-sectional observational study was conducted in order to assess the distribution of AMH and AMHRII SNPs in two cohorts, one of healthy women (N = 100) and the control group and the IVF/ICSI group (N = 151) consisted of women undergoing IVF/ICSI treatment for infertility. Furthermore, a prospective longitudinal observational study was performed on the latter group to assess possible associations of these SNPs with patients' characteristics and controlled ovarian stimulation (COS) and pregnancy outcome.

The effect of CRH and its inhibitor, antalarmin, on in vitro growth of preantral mouse follicles, early embryo development, and steroidogenesis.

In vitro growth systems of preantral follicles allow studying the effect of various endocrine, paracrine, and autocrine factors on follicular growth and oocyte maturation. CRH is a 41-amino-acid neuropeptide responsible for endocrine, autonomic, immunological, and behavioral responses of mammals to stress and has two receptors, CRH receptor type 1 (CRH-R1) and CRH-R2. Antalarmin, a CRH-R1 antagonist, has been used to elucidate the role of CRH in stress, inflammation, and reproduction.

LH receptor gene expression in cumulus cells in women entering an ART program.

Purpose: Luteinizing hormone (LH) exerts its actions through its receptor (LHR), which is mainly expressed in theca cells and to a lesser extent in oocytes, granulosa and cumulus cells. The aim of the present study was the investigation of a possible correlation between LHR gene and LHR splice variants expression in cumulus cells and ovarian response as well as ART outcome.

Methods: Forty patients undergoing ICSI treatment for male factor infertility underwent a long luteal GnRH-agonist downregulation protocol with a fixed 5-day rLH pre-treatment prior to rFSH stimulation and samples of cumulus cells were collected on the day of egg collection.

Expression profiling of vulvar carcinoma: clues for deranged extracellular matrix remodeling and effects on multiple signaling pathways combined with discrete patient subsets.

The molecular mechanisms of vulvar squamous cell carcinoma (VSCC) remain obscure. To this end, we investigated systematically for the first time the expression profile of VSCC using the microarray technology, in a total of 11 snap-frozen samples, from five VSCC patients covering early and advanced stages of VSCC undergoing radical surgery and from six matched healthy controls. All experiments were performed using Affymetrix Human Genome U133A 2.

Genetic profile of SNP(s) and ovulation induction.

Obtaining an adequate number of good quality oocytes while minimizing adverse drug reactions (ADRs) and cycle cancellation rates is considered the gold standard in controlled ovarian hyperstimulation (COH) for fertility treatment. Patients who undergo IVF/ICSI cycles tend to present with different responses to exogenous gonadotrophin administration. Research has shown that the secret probably lies in the various single nucleotide polymorhisms (SNPs) in their receptor genes.

p16 INK4A is a strong biomarker for cervical intraepithelial neoplasia and invasive cervical carcinoma: a reappraisal.

To assess the role of p16( INK4A), bcl-2, and p53 in cervical cancer screening, we conducted a retrospective trial of prospectively collected data. Sixty two women with abnormal Pap smears were subjected to colposcopy and biopsies from any abnormal lesion. Human papillomavirus (HPV)-DNA typing, histology, and immunochemistry for p16(INK4A), bcl-2, and p53 were performed for these women.
