The recently described oak gall wasp Zapatella davisae Buffington & Melika (Hymenoptera: Cynipidae) has caused extensive damage and mortality to black oak trees, Quercus velutina L. (Fagales: Fagaceae), in coastal parts of New England, United States. Like many newly described and/or newly introduced species, it is unclear how long populations of Z. davisae have existed in this region. However, as this species forms galls on the woody-tissue of its host, it may be possible to obtain historical information about changes in its population size by examining the presence of galls in relation to annual growth nodes. Here, we explore the utility of this approach to determine population size changes in Z. davisae densities on Nantucket, Martha's Vineyard, and Cape Cod, Massachusetts, through dissection of black oak branches. In addition, we calculated parasitism rates during the years of study and obtained morphological and molecular identifications for the parasitoids associated with Z. davisae. Our results show significant changes in population sizes, with higher levels of parasitism at sites on Martha's Vineyard and Cape Cod compared to sites on Nantucket. In addition, morphological examinations, in combination with DNA sequencing, identified the associated parasitoids as five species in the genus Sycophila Walker (Hymenoptera: Eurytomidae). We comment that considerable morphological variation within several of these recovered species was observed, present the first record of males for a species from which only females have been described, and suggest that future work is required to clarify the species boundaries for this important parasitoid group.

Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae) is a preponderant endoparasitoid wasp, attacking the larvae of many lepidopteran pests. We present the first body transcriptome dataset for M...
Parasitoid wasps are among the most speciose animals, yet have relatively few available genomic resources. We report a draft genome assembly of the wasp Diachasma alloeum (Hymenoptera: Braconidae), a ...
Gall bladder cancer (GBC) is associated with abdominal pain, lump, nausea, vomiting, and jaundice due to either gall bladder mass or the involved adjacent peritoneal structures. Gall bladder cancer pr...
The actin nucleator Arp2/3 generates pushing forces in response to signals integrated by SCAR and WASp. In Drosophila, the activation of Arp2/3 by WASp is specifically required for Notch signaling fol...
Gall bladder anomalies may be in the form of abnormalities in the shape, position, or number. It could be true duplication being completely separated or Y-shaped being united with single cystic duct.
Dendritic cells (DC) play a key role in the pathogenesis of allergic diseases. The regulation of blood dendritic cells in patients with hymenoptera venom allergy before and during immune t...
The aim of this study is to show that flow cytometry can be an accurate tool to help physicians regarding the diagnosis, the SIT decision and the SIT arrest of hymenoptera venom allergy. ...

It is a cross sectional study in which we are tying to determine frequency of type of gall stones in our setup(Lahore, Pakistan).
This study included group (A) (60 patients with liver cirrhosis and complaining of gall stone) in whom LC was done using traditional method (TM) by clipping both cystic duct and artery and...
Venoms from animals of the phylum Arthropoda. Those most investigated are from scorpions and spiders of the class Arachnidae and from ant, bee, and wasp families of the Insecta order Hymenoptera. The venoms contain protein toxins, enzymes, and other bioactive substances and may be lethal to man.
ANTHRAX outbreak that occurred in 1979 and was associated with a research facility in Sverdlovsk, in the Ural mountain region of central RUSSIA. Most victims worked or lived in a narrow zone extending from the facility. The zone of anthrax-caused livestock mortality paralleled the northerly wind that prevailed shortly before the outbreak. It was concluded that an escape of ANTHRAX caused outbreak.
Venoms produced by the wasp (Vespid) family of stinging insects, including hornets; the venoms contain enzymes, biogenic amines, histamine releasing factors, kinins, toxic polypeptides, etc., and are similar to bee venoms.
WASP protein is mutated in WISKOTT-ALDRICH SYNDROME and is expressed primarily in hematopoietic cells. It is the founding member of the WASP protein family and interacts with CDC42 PROTEIN to help regulate ACTIN polymerization.
Biological adaptation, such as the rise of EPINEPHRINE in response to exercise, stress or perceived danger, followed by a fall of epinephrine during RELAXATION. Allostasis is the achievement of stability by turning on and turning off the allostatic systems including the IMMUNE SYSTEM; the AUTONOMIC NERVOUS SYSTEM and NEUROENDOCRINE SYSTEMS.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
