New alien insect pests to Portugal on urban ornamental plants and additional data on recently introduced species

The spread of invasive pests is an important topic in pest control and early detection is crucial for containment of invasive aliens. In this study the results of recent surveys on alien insects of ornamental urban plants in Portugal are reported. Overall, 13 alien species associated with allochthonous ornamental plants were recorded. Seven of these pests are new to the Portuguese fauna: Tinocallis kahawaluokalani (Kirkaldy); Illinoia liriodendri (Monell); Appendiseta robiniae (Gillette) (Hemiptera: Aphididae); Acizzia jamatonica (Kuwayama) (Hemiptera: Psyllidae); Dasineura gleditchiae (Osten Sacken); Obolodiplosis robiniae (Haldeman) (Diptera: Cecidomyiidae); and Phytoliriomyza jacarandae Steyskal & Spencer (Diptera: Agromyzidae). Additional distribution data are also provided for other recently introduced alien pests in Portugal: Myzocallis (Lineomyzocallis) walshii (Monell) (Hemiptera: Aphididae); Platycorypha nigrivirga Burckhardt; Glycaspis brimblecombei Moore (Hemiptera: Psyllidae); Calophya schini Tuthill (Hemiptera: Calophyidae); Corythucha ciliata (Say) (Hemiptera: Tingidae); and Lantanophaga pusillidactylus (Walker) (Lepidoptera: Pterophoridae). Three species in particular (Illinoia liriodendri, Obolodiplosis robiniae and Phytoliriomyza jacarandae) were not previously found in the Iberian Peninsula. Details on current distribution, host plants and biological remarks are given for each species. Possible origin areas, pathways and impacts are also discussed.     

Acetyltransferase p300 regulates NBS1-mediated DNA damage response

The role of p300 in DNA damage response is unclear. To understand how ATM-dependent phosphorylation of p300 affects its function in response to DNA damage, we present evidence that S106 of p300, which is phosphorylated by ATM, regulates stability of NBS1 and recruitment into damaged DNA, possibly leading to regulation of DNA repair. Non-phosphorylatable p300 (S106A) destabilized NBS1 and decreased NBS1–p300 interaction. The recruitment of NBS1 into damaged DNA was impaired in the presence of S106A. Also, a dominant negative p300 lacking enzymatic activity induced destabilization of NBS1, suggesting that its acetyltransferase is required for NBS1 stability. These results indicate that phosphorylation of p300 can regulate NBS1-mediated DNA damage response, and that these events occur in an acetylation-dependent manner.

Leptin to high-molecular-weight adiponectin ratio is independently correlated with carotid intima-media thickness in men,but not in women

Background: The leptin:adiponectin ratio (L:A ratio) is an independent predictor of carotid intima-media thickness (CIMT).

Objective: To evaluate whether the leptin:high-molecular-weight adiponectin ratio (L:HA ratio) is associated with CIMT in the general population.

Methods: We investigated the relationship between the L:HA ratio and CIMT in 233 Japanese study participants (106 men and 127 women).

Results: After adjustment for confounding factors, CIMT was significantly correlated with the log L:HA ratio (β?=?0.11, p?=?0.014) in men, whereas no correlation was observed in women (β?=?0.01, p?=?0.50).

Conclusion: The L:HA ratio is closely correlated with CIMT in men, but not in women.     

Direct demonstration of NCAM cis-dimerization and inhibitory effect of palmitoylation using the BRET technique

Biological activity of the neural cell adhesion molecule (NCAM) depends on both adhesion and activation of intra-cellular signaling. Based on in vitro experiments with truncated extra-cellular domains, several models describing homophilic NCAM trans- and cis-interactions have been proposed. However, cis-dimerization in living cells has not been shown directly and the role of the cytoplasmic part in NCAM dimerization is poorly understood. Here, we used the bioluminescence resonance energy transfer (BRET²) technique to directly demonstrate that full-length NCAM cis-homodimerizes in living cells. Based on BRET²50 values we suggest that the intra-cellular part of NCAM inhibits cis-dimerization, an effect mainly dependent on the palmitoylation sites.

Les Abeilles de Martinique (Antilles françaises) et leurs relations avec la flore butinée (Hymenoptera: Apoidea: Megachilidae,Apidae)

Checklist of bees from Martinique (French West Indies) and their relations with visited flowers (Hymenoptera: Apoidea: Megachilidae, Apidae). An annotated checklist of the bees (Hymenoptera: Apoidea: Anthophila) of Martinique, Lesser Antilles is presented. The bee fauna is constituted by 14 species: one endemic; five known only from the Insular Caribbean; four that occur both on mainland and the West Indies and three adventive species to the West Indies. Seven species are new island records: Megachile (Eutricharaea) concinna Smith 1879, Megachile (Pseudocentron) vitraci Pérez 1884, Centris (Hemisiella) barbadensis Cockerell 1939, Centris (Centris) decolorata Lepeletier 1841, Centris (Centris) versicolor (Fabricius 1775), Exomalopsis (Exomalopsis) analis Spinola 1853 and Exomalopsis (Exomalopsis) similis (Cresson 1865). The list is arranged with data from literature and field researches carried out by the junior author between 2006 and 2014. A list of the visited flowers along with ecological notes for each species is also given.     

The frequency of transposition of the maize element Activator is not affected by an adjacent deletion

Summary The maize mutable allele bz-m2 (Ac), which arose from insertion of the 4.6 kb Ac element in the bz (bronze) locus, gives rise to stable bz (bz-s) derivatives that retain an active Ac element closely linked to bz. In the derivative bz-s:2114 (Ac), the Ac element is recombinationally inseparable from bz and transposes to unlinked sites at a frequency similar to that in the progenitor allele bzm2 (Ac). Both alleles have been cloned and sequenced. The bz-s:2114 (Ac) mutation retains Ac at the original site of insertion, but has lost a 789 pb upstream bz sequence adjacent to the insertion, hence the stable phenotype. The 8 bp target site direct repeat flanking the Ac insertion in the bz-m2 (Ac) allele is deleted in bz-s: 2114 (Ac), yet the Ac element is not impaired in its ability to transpose. The only functional Ac element in bz-s:2114 (Ac) is the one at the bz locus: in second-cycle derivatives without Ac activity, the loss of Ac activity correlated with the physical loss of the Ac element from the bz locus. The deletion endpoint in bz-s: 2114 (Ac) corresponds exactly with the site of insertion of a Ds element in a different bz mutation, which suggests that there may be preferred integration sites in the genome and that the deletion originated as the consequence of an abortive transposition event. Finally, we report two errors in the published Ac sequence.

A biomarker of tissue damage,lactate dehydrogenase,is associated with fibulin-1 and oxidative stress in blacks: the SAfrEIC study

Context: Extracellular matrix (ECM) remodeling and oxidative stress is present in hypertension and associated arterial stiffness, but little is known on the physiological link among lactate dehydrogenase (LDH), fibulin-1, and reactive oxygen species (ROS).

Objective: The objective of this study is to explore the link among a marker of tissue damage (LDH), fibulin-1 (as ECM biomarker), and ROS.

Methods: We included 316 black and 305 white South Africans and determined the above-mentioned biomarkers along with additional cardiometabolic risk factors.

Results: LDH associated positively with fibulin-1 (β?=?0.23; p?<?0.001) and ROS (β?=?0.11; p?=?0.30) in blacks only.

Conclusion: Our finding suggests that increased circulating levels of LDH may be due to early ECM remodeling and oxidative stress in blacks that are subjected to detrimental and uncontrolled lifestyle risk factors.     

Revision of the Indo‐African Pachycerus Schoenherr, 1823, with a description of four new species (Coleoptera: Curculionidae: Lixinae)

The Indo‐African species of the genus Pachycerus (Curculionidae: Lixinae: Cleonini) are revised. The identification of Cleonus senegalensis Gyllenhal, 1834 is discussed, its holotype rediscovered and the synonymy between C. senegalensis and Ammocleonus hieroglyphicus (Olivier, 1807) is confirmed. A neotype is established for Pachycerus opimus (Gyllenhal, 1834). Lectotypes for Pachycerus vestitus (Fåhraeus, 1834), Pachycerus badeni (Faust, 1888), and Pachycerus sellatus Faust, 1904 are designated. Pachycerus sahelicus sp. nov. (type locality: Senegal, Bambey), Pachycerus hippali sp. nov. (type locality: Saudi Arabia: Jeddah, Taif), Pachycerus barclayi sp. nov. (type locality: southern India: Manapparai), and Pachycerus simonae sp. nov. (type locality: Morocco, Western Sahara, Cap Boujdour) are described. Some remarks on taxonomy and biogeography of the species are added.
