Tettigoniidae (Orthoptera) ovipositing in old galls of Dryocosmus kuriphilus (Hymenoptera: Cynipidae)

2016

Authors report some biological notes on two species of Orthoptera Tettigoniidae emerged from old spongy-woody galls of Dryocosmus kuriphilus Yasumatsu, 1951 collected in April 2015 from some areas of Sicily (Italy): Leptophyes sicula Kleukers, Odé et Fontana, 2010 (Phaneropterinae) and Cyrtaspis scutata (Charpentier, 1825) (Meconematinae). Between the end of April and the first days of May 30 neanids emerged from the galls, were reared and their cycle followed. While L. sicula laid eggs in groups, C. scutata laid single eggs inside the galls; both species have shown that in a few years they adapted in exploiting this new shelter for egg laying. No interaction with the gall inducing insect w…

Meconium microbiota types dominated by lactic acid or enteric bacteria are differentially associated with maternal eczema and respiratory problems in…

2013

Background Culture-dependent methods have shown that meconium, the newborn's first intestinal discharge, is not sterile, but the diversity of bacteria present in this material needs to be further characterized by means of more sensitive molecular techniques. Objective Our aims were to characterize molecularly the meconium microbiota in term infants, to assess whether it contributes to the future microbiota of the infants' gastrointestinal tract, and to evaluate how it relates to lifestyle variables and atopy-related conditions. Methods We applied high-throughput pyrosequencing of the 16S rRNA gene to study the meconium microbiota in twenty term newborns from a Spanish birth cohort. For comp…

Variability of isozyme pattern, chromosome number, and latex colour and components in the closely related Papaver duhium L. and P. lecoqii Lamotte in…

1995

Summary The variability of nine different isozyme systems, chromosome number, colour of fresh and dried latex and presence or absence of meconic acid was investigated in altogether 45 populations of Papaver dubium and P. lecoqii mainly from C Europe. It was found that P. dubium is hexaploid with 2n = 42 chromosomes, has brown dried latex, and contains meconic acid. P. lecoqii is tetraploid with 2n = 28 chromosomes, has red dried latex, and lacks meconic acid. The two taxa can also be distinguished by differences in three of the nine isozymes analysed, and are almost completely monomorphic for their respective isozyme pattern. It is concluded that the two taxa, which cannot be reliably disti…

Occurrence of biomarkers of pesticide exposure in non-invasive human specimens.

2015

Biomonitoring has been used in many types of investigations, including national programmes and epidemiological studies, to explore the occurrence of biomarkers of pesticide exposure in the general population or relevant groups. This review discusses recent studies that measure levels of biomarkers of pesticide exposure in non-invasive human specimens such as urine, breast milk, meconium and hair. Specific and non-specific metabolites of organophosphate and pyrethroid insecticides have been widely investigated in urine, where some of the suitable biomarkers present rates of detection higher than 80%, which stand for an ongoing chronic exposure to traces of these chemicals. Hair is a promisin…

Evolution of gynoecium morphology in Old World Papaveroideae: a combined phylogenetic/ontogenetic approach.

2011

PREMISE OF THE STUDY: The correct assessment of homology is an important prerequisite for reconstructing phylogenetic relationships and character evolution. Old World Papaveroideae (Papaver, Meconopsis, Roemeria, Stylomecon) show substantial diversity in gynoecium and capsule morphology. In particular, capsules can have distinct styles (Meconopsis p.p., Stylomecon) or a sessile stigmatic disc (Papaver). Molecular phylogenetic analyses of Old World Papaveroideae had shown that neither taxa with styles nor those with stigmatic discs represent monophyletic lineages. We here investigate whether either styles or stigmatic discs have arisen repeatedly during the diversification of Old World Papav…

Meconial peritonitis in a rare association of partial ileal apple-peel atresia with small abdominal wall defect.

2014

Intestinal atresia type III B (apple peel) and gastroschisis are both congenital malformations who require early surgical correction in neonatal age. Their association is very rare. We present the case of a full term infant with partial apple peel ileal atresia and a small defect of the anterior abdominal wall, complicated by in utero intestinal perforation and subsequent meconial peritonitis. We observed a partial atresia of small intestine, with involvement of terminal ileus savings of jejunum and a large part of the proximal ileum, small anterior abdominal wall defect with herniation of few bowel loops, intestinal malrotation. Paralytic ileus and infections are the main causes of morbidi…

Congenital cytomegalovirus related intestinal malrotation: a case report

2016

Background: Cytomegalovirus is the most common cause of congenital infection in the developed countries. Gastrointestinal involvement has been extensively described in both adult and paediatric immunocompromised patients but it is infrequent in congenital or perinatal CMV infection. Case presentation: We report on a case of coexistent congenital Cytomegalovirus infection with intestinal malrotation and positive intestinal Cytomegalovirus biopsy. At birth the neonate showed clinical and radiological evidence of intestinal obstruction. Meconium passed only after evacuative nursing procedures; stooling pattern was irregular; gastric residuals were bile-stained. Laparatomy revealed a complete i…

High frequencies of antibiotic resistance genes in infants' meconium and early fecal samples

2016

The gastrointestinal tract (GIT) microbiota has been identified as an important reservoir of antibiotic resistance genes (ARGs) that can be horizontally transferred to pathogenic species. Maternal GIT microbes can be transmitted to the offspring, and recent work indicates that such transfer starts before birth. We have used culture-independent genetic screenings to explore whether ARGs are already present in the meconium accumulated in the GIT during fetal life and in feces of 1-week-old infants. We have analyzed resistance to β-lactam antibiotics (BLr) and tetracycline (Tcr), screening for a variety of genes conferring each. To evaluate whether ARGs could have been inherited by maternal tr…

Analytical methods for human biomonitoring of pesticides. A review.

2015

Biomonitoring of both currently-used and banned-persistent pesticides is a very useful tool for assessing human exposure to these chemicals. In this review, we present current approaches and recent advances in the analytical methods for determining the biomarkers of exposure to pesticides in the most commonly used specimens, such as blood, urine, and breast milk, and in emerging non-invasive matrices such as hair and meconium. We critically discuss the main applications for sample treatment, and the instrumental techniques currently used to determine the most relevant pesticide biomarkers. We finally look at the future trends in this field.
