Attenuation of sucrose consumption in mice by chronic mild stress and its restoration by imipramine
1995
Chronic exposure to mild unpredictable stressors (CMS) has previously been found to reduce the consumption of palatable, sweet solutions in rats. In the present study, the utility of this procedure was assessed in mice. Male AP mice subjected to CMS showed reduced consumption of a 2% or 4% sucrose solution. This effect was reversed by chronic (3 weeks) treatment with the tricyclic antidepressant imipramine (20 mg/kg per day). These results extend previous reports of a generalized decrease in sensitivity to reward (anhedonia) in rats caused by CMS and the efficacy of antidepressant treatment in this paradigm. Chronic unpredictable mild stress in mice appears to provide a realistic animal mod…
Differential Infectivity of Two Pseudomonas Species and the Immune Response in the Milkweed Bug, Oncopeltus fasciatus (Insecta: Hemiptera)
2002
Pseudomonas aeruginosa and Pseudomonas putida show a profound differential infectivity after inoculation in Oncopeltus fasciatus. Whereas P. putida has no significant impact on nymphs, P. aeruginosa kills all experimental animals within 48 h. Both Pseudomonas species, however, induce the same four hemolymph peptides in O. fasciatus. Also injection of saline solution and injury induced these peptides. In general peptide induction was stronger in nymphs than in adult males. A significantly higher number of nymphs survived a challenge with P. aeruginosa when an immunization with P. putida preceded. The antibacterial properties of the hemolymph were demonstrated in inhibition experiments with P…
Gamete intrafallopian transfer in the treatment of infertility: the first series at the University of Palermo
1986
Twenty-six couples with unexplained infertility (UI), nine women with repeated failures of artificial insemination with donor semen (AID), three women with mild endometriosis, three with periadnexal adhesions, one with hostile (not immunologic) cervical mucus, and one couple in which the male partner was affected by asthenospermia were treated by the gamete intrafallopian transfer (GIFT) technique. Three different protocols for controlled ovarian hyperstimulation were used, and an adequate follicular growth and oocyte maturation were achieved in all cases. Seventeen pregnancies were obtained, for a global pregnancy rate of 38.6%. Two pregnancies (11.7%) ended in clinical abortions, and one …
The genus Tuponia Reuter, 1875 in Romania, with two new synonymies (Heteroptera: Miridae)
2021
Based on recently collected material and on type specimens deposited in the collections of Muzeul de Istorie Naturală “Grigore Antipa”, Bucharest, Romania, and of the Zoologische Museum, Universität Hamburg, Germany, the following new synonymies are proposed: Tuponia (Chlorotuponia) prasina (Fieber, 1864) = Tuponia (Chlorotuponia) linnavuorii Wagner, 1961, syn. n.; Tuponia (Tuponia) montandoni Reuter, 1899 = Tuponia (Tuponia) macedonica Wagner, 1957, syn. n. Lectotype and paralectotype are designated for Tuponia (Tuponia) montandoni Reuter, 1899. Tuponia (Chlorotuponia) hippophaes (Fieber, 1861), Tuponia (Tuponia) arcufera Reuter, 1879 and Tuponia (Tuponia) elegans (Jakovlev, 1867) are reco…
Chilocoris capensis n. sp., the first species of the genus Chilocoris Mayr, 1865 (Hemiptera: Heteroptera: Cydnidae) recorded in the Republic of South…
2016
Chilocoris capensis n. sp. collected from fallen ripe figs of broom cluster fig Ficus sur Forsskal, 1775, the first burrower bug species of the genus Chilocoris Mayr, 1865 recorded in the Republic of South Africa, is described and compared with Chilocoris laevicollis Horvath, 1919, the morphologically most closely allied Afrotropical species. Additionally, an annotated checklist of burrower bug species recorded in the Republic of South Africa is provided. The known biology of Afrotropical Chilocoris species is briefly summarized.
New Afrotropical species of the genus Coridiellus J.A. Lis, 1990 with a key to its species (Hemiptera: Heteroptera: Dinidoridae)
2020
Coridiellus pseudocyclopeltus, a new species of the dinidorid subfamily Dinidorinae, is described from Zaire and is compared with Coridiellus cyclopeltus (Distant, 1890). It is the seventh species of this genus known from Afrotropical Region. A key to all the species of the genus Coridiellus is also provided. Male parameres are used for identification and their photographs are given for the first time for all species of the genus.
Zofenopril and ramipril in patients with left ventricular systolic dysfunction after acute myocardial infarction: A propensity analysis of the Surviv…
2016
Introduction: This was a propensity score analysis of the prospective, randomized, double-blind Survival of Myocardial Infarction Long-term Evaluation (SMILE) 4 study in which one-year treatment with zofenopril 60 mg plus acetylsalicylic acid (ASA) 100 mg gave superior results compared to ramipril 10 mg plus ASA in terms of death or hospitalization for cardiovascular causes in patients with acute myocardial infarction (AMI) complicated by left ventricular dysfunction (LVD). Materials and methods: A total of 716 patients of the intention-to-treat population were divided into homogeneous propensity quintiles (Q) using a logistic regression model (QI: best risk profile; QV: worst risk profile)…
Functional networks of motor inhibition in conversion disorder patients and feigning subjects
2016
The neural correlates of motor inhibition leading to paresis in conversion disorder are not well known. The key question is whether they are different of those of normal subjects feigning the symptoms. Thirteen conversion disorder patients with hemiparesis and twelve healthy controls were investigated using functional magnetic resonance tomography under conditions of passive motor stimulation of the paretic/feigned paretic and the non-paretic hand. Healthy controls were also investigated in a non-feigning condition. During passive movement of the affected right hand conversion disorder patients exhibited activations in the bilateral triangular part of the inferior frontal gyri (IFG), with a…

Illustrations of the tarsi and male genitalia are presented for the first time.
Evolutionary Hysteresis and Ratchets in the Evolution of Periodical Cicadas
2019
It has been previously hypothesized that the perfectly synchronized mass emergence of periodical cicadas (Magicicada spp.) evolved as a result of a switch from size-based to age-based emergence. In the former case, cicada nymphs emerge immediately (at the first opportunity) on reaching maturity, whereas in the latter case, nymphs wait in order to emerge at a specific age. Here we use an individual-based model to simulate the cicada life cycle and to study the evolution of periodicity. We find that if age-based emergence evolves in a constant abiotic environment, it typically results in a population that is protoperiodic, and synchronous emergence of the whole population is not achieved. How…
