Herpies

Recent survey efforts in Costa Rica have documented many new species of planthoppers, primarily in the families Derbidae and Cixiidae, on palms. Recently, a specimen was collected sweeping palms in the Los Angeles cloud forest in Costa Rica and was identified as belonging to the genus Herpis (Derbidae). It was subsequently determined to represent a previously undescribed species. Herein, the new species, Herpis circumsoros Bahder & Bartlett sp. n. is described with supplemental molecular data for the cytochrome c oxidase subunit I (COI) gene and 18S rRNA gene to support placement of the new species in the genus Herpis...

Recent survey efforts in the Neotropics have documented a variety of new species of planthoppers associated with palms. Herein, a new species, Herpis soros sp. n., is described from palms in lowland tropical rainforest from Costa Rica. Other species in the genus (H. metcalfi, H. albida, and H. fuscovittata) are evaluated to provide an updated diagnosis of the genus Herpis. The New World Phaciocephalus is examined because two species were described in the genus Herpis with P. fimbriolata being recorded for both Herpis and Phaciocephalus...

We present surveys of derbid planthoppers associated with coconut (Cocos nucifera L.) and oil palm (Elaeis guineensis Jacq.) collected in Northeastern (Sergipe) and North (Pará and Roraima) Brazil. The surveys were intended to contribute to our knowledge of possible vectors of phytoplasmas or other phloem-restricted plant pathogens. Eight derbid taxa were found, two in the subfamily Cedusinae, tribe Cedusini (Cedusa yipara Kramer and C. yowza Kramer) and six in the subfamily Derbinae, tribe Cenchreini: Herpis sp...

The aim of this study is to describe the development of nanoemulsion-loaded hydrogels to deliver pentyl gallate (PG), a gallic acid n-alkyl ester, through the skin. PG is an antioxidant agent; however, it seems to be a promising agent for herpis labialis treatment. Aristoflex AVC® and chitosan were used as gelling agents for nanoemulsion thickening. The developed formulations presented suitable PG content (94.4-100.3% w/w), nanometric droplet sizes (162-297 nm), high zeta potentials, and a non-Newtonian pseudoplastic behavior...

GH is important in metabolic control, and mice with disruption of the gene encoding the GH receptor (GHR) and GH binding protein (GHR-/- mice) are dwarf with low serum IGF-1 and insulin levels, high GH levels, and increased longevity, despite their obesity and altered lipid and metabolic profiles. Secondary complications of high-fat diet (HFD)-induced obesity are reported to be associated with hypothalamic inflammation and gliosis. Because GH and IGF-1 can modulate inflammatory processes, our objective was to evaluate the effect of HFD on hypothalamic inflammation/gliosis in the absence of GH signaling and determine how this correlates with changes in systemic metabolism...

Herpis simplex 1 infection involving the orophaiynx in an adult is a rare entity, as, primary infection with type I herpes simplex is commonly seen in children and c auses a severe vesicular and ulcertive stomatitis and occasionally spreads to the oropharynx.

The adaptive evolution of the hemagglutinin (HA) segment of the human influenza H1N1 and H3N2 viruses is not well understood due to antigenic mutations under selection pressures. This paper identified significant antigenic selection sites and discussed the structural relevance of these mutations. We discovered four positively selected sites for H1N1 (position 206 for the 1A lineage - 2009 swine influenza, and positions 144, 190, and 192 for the 1B lineage), and eight positively selected sites for H3N2 with the loop regions near residues 157 and 225 as the latest antigenic mutations, which may be targeted for vaccine development...

This paper describes a modification of the combined bilateral sagittal split osteotomy and total subapical osteotomy procedure; a representative case treated with this approach is presented. In addition, diagnostic and treatment planning considerations for the comprehensive surgical-orthodontic therapy of individuals presenting with differential sagittal discrepancy between the mandibular corpus and symphysis are discussed, along with limitations of diagnostic criteria commonly used in cephalometric appraisal of the facial soft tissue outline...

This study was undertaken to quantitate the effects of needle trauma to the arterial wall during microvascular anastomoses. End-to-end anastomoses performed on rat femoral arteries were used as a model. Two weeks post-anastomoses, the specimens were processed and measured with a planimeter. The results were analysed statistically to evaluate the effects of different types of needles on the arterial wall. We found significant thickening of the arterial wall (P less than 0.01) but no difference in the amount of thickening between any of the needles evaluated...

This monitoring and evaluation study of third molar surgery complications took place over a 6-month period of time. The goal of the study was to determine complication rates following third molar extraction. A comparison was made between the staff's and residents' post-operative complication rates and patients receiving tetracycline powder in the extraction sockets vs. no antibiotics. Complication rates were compared in males vs. females, and in four different age groups. The study helped improve patient care by showing that alveolar osteitis rates decreased when all patients received topical tetracycline...
