Mite communities (Acari, Mesostigmata) associated with Ips typographus (Coleoptera, Scolytidae) in managed and natural Norway spruce stands in Central Europe
The objective of this study was to compare mesostigmatid mite communities associated with the Norway spruce pest Ips typographus in managed and natural forest stands separated by spruce-free belt. The study sites were located in Białowieża National Park (NE Poland) as well as in the Izery Mountains (Szklarska Poręba Forest District — SW Poland), which were destroyed in 1981–1987 by an ecological disaster. In total, 30 Borregard pipe traps containing the commercial attractant Ipsodor W (Chemipan, Poland) were set up at each study site and collected in August 2010. In total, 7214 bark beetles and 1804 mites were c...

Ulcerative dermatitis in C57BL/6 mice exhibits an oxidative stress response consistent with normal wound healing.
Abstract Ulcerative dermatitis (UD) is a common syndrome of unknown etiology that results in profound morbidity in C57BL/6 mice and lines on a C57BL/6 background. The lesions are due to severe pruritus-induced self-trauma, progressing from superficial excoriations to deep ulcerations. UD may be behavioral in origin, with ulcerative lesions resulting from self-mutilating behavior in response to unresolved inflammation or compulsion. Alternatively, abnormal oxidative damage may be a mechanism underlying UD. To evaluate whether UD behaves similarly to normal wounds, consistent with a secondary self-inflicted lesion, o...

Markers for heightened monitoring, imminent death, and euthanasia in aged inbred mice.
Abstract The goal of this study was to identify objective criteria that would reliably predict spontaneous death in aged inbred mice. We evaluated male and female AKR/J mice, which die at a relatively young age due to the development of lymphoma, as well as male C57BL/6J and BALB/cByJ mice. Mice were implanted subcutaneously with an identification chip that also allowed remote measurement of body temperature. Temperatures and body weights were measured weekly until spontaneous death occurred or until euthanasia was performed for humane reasons. In AKR/J mice, hypothermia and weight loss began about 4 wk prior to de...

Expression of Maspin in the Early Pregnant Mouse Endometrium and Its Role during Embryonic Implantation.
Abstract Maspin (serpin B5), a tumor-suppressing member of the serine protease inhibitor family, participates in cell migration, adhesion, invasion, and apoptosis. These processes are also critical for embryo implantation, but the role of maspin in embryo implantation remains poorly understood. The aim of the present study was to investigate the spatiotemporal expression of maspin in early pregnant mouse endometrium and its role in embryo implantation. Real-time quantitative PCR analysis, immunohistochemistry, and Western blotting were used to detect mRNA and protein expression of maspin in the endometria of nonpre...

Genomic analysis and pathogenic characteristics of lymphocytic choriomeningitis virus strains isolated in Japan.
Abstract Lymphocytic choriomeningitis virus (LCMV) is a zoonotic pathogen of which mice are the natural reservoir. Different strains and clones of LCMV show different pathogenicity in mice. Here we determined the complete genomic sequences of 3 LCMV strains (OQ28 and BRC which were isolated from mice in Japan and WE(ngs) which was derived from strain WE). Strains OQ28 and BRC showed high sequence homology with other LCMV strains. Although phylogenetic analyses placed these 2 Japanese strains in different subclusters, they belonged to same cluster of LCMV isolates. WE(ngs) and WE had many sequence substitutions betw...

Modeling perimenopause in sprague-dawley rats by chemical manipulation of the transition to ovarian failure.
We examined long-term (11 to 20 mo), dose-dependent effects of VCD on reproductive function in 1- and 3-mo-old female Sprague-Dawley rats. Twenty-five daily doses of VCD (80 or 160 mg/kg daily compared with vehicle alone) depleted ovarian follicles in a dose-dependent fashion in rats of both ages, accelerated the onset of acyclicity, and caused dose-dependent increases in follicle-stimulating hormone that exceeded those naturally occurring with age in control rats but left serum levels of 17β-estradiol unchanged, with continued ovarian production of androstenedione. High-dose VCD caused considerable nonovarian toxicities ...

Abstract A 1-y-old male miniature pig housed in our laboratory facility was evaluated for weight loss and rough coat condition. CBC results revealed neutrophilia. Radiography of the thoracic area showed increased opacity throughout the thoracic cavity except for the right caudal lobe. (18)F-labeled fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET-CT) revealed elevated standard uptake values in the area corresponding to the radiologic findings. Follow-up thoracic radiography taken 2 wk after FDG-PET-CT showed several interval changes, including markedly decreased opacity throughout the en...

Effects of Extended-Release Injectable Naltrexone on Self-Injurious Behavior in Rhesus Macaques (Macaca mulatta).
This study is the first to assess the efficacy of extended-release naltrexone in the pharmacologic treatment of SIB in rhesus macaques (Macaca mulatta). In an acute pharmacokinetic study of 4 macaques, we determined the mean naltrexone plasma concentration was maintained above the therapeutic level (2 ng/mL) after administration of a single dose (20 mg/kg) of 28-d extended-release naltrexone throughout the release period. For a subsequent treatment study, we selected 8 singly housed macaques known to engage in SIB. The study comprised a 4-wk baseline phase; an 8-wk treatment phase, during which each macaque received 2 dose...

Variation in CCL3L1 Copy Number in Rhesus Macaques (Macaca mulatta).
Abstract We used real-time quantitative PCR (qPCR) methodology to examine copy number variation (CNV) of the CCL3L1 gene among pure Indian-origin, pure Chinese-origin, and hybrid Indian-Chinese rhesus macaques (Macaca mulatta). CNV among purebred macaques fell within expected ranges, with Indian macaques having lower copy numbers than those of Chinese macaques. Compared with the purebred macaques, Indian-Chinese hybrid rhesus macaques showed much greater variance in copy number and an intermediate average copy number. Copy numbers of CCL3L1 in rhesus macaque trios (sire, dam, and offspring) were consistent with Men...

Nonhuman primate models.
Abstract Two captive cottontop tamarins (Sanguinus oedipus) died within 5 d of each other from systemic infection by Francisella tularensis (tularemia). One tamarin experienced mild clinical signs, including malaise, anorexia, and a mucoid nasal discharge for 4 d before death, whereas the other experienced a more rapid progression of disease that lasted less than 24 h. Differential diagnoses included gram-negative septicemia by an organism such as Escherichia coli, Salmonella, or Yersinia; protozoal infection such as Toxoplasma gondii or an acute viral infection such as lymphocytic choriomeningitis. F. tularensis i...

Interpatch foraging in honeybees-rational decision making at secondary hubs based upon time and motivation.
Abstract For honeybees, Apis mellifera, the hive has been well known to function as a primary decision-making hub, a place from which foragers decide among various directions, distances, and times of day to forage efficiently. Whether foraging honeybees can make similarly complex navigational decisions from locations away from the hive is unknown. To examine whether or not such secondary decision-making hubs exist, we trained bees to forage at four different locations. Specifically, we trained honeybees to first forage to a distal site "CT" 100 m away from the hive; if food was present, they fe...

Computing evolutionary distinctiveness indices in large scale analysis.
We present optimal linear time algorithms for computing the Shapley values and 'heightened evolutionary distinctiveness' (HED) scores for the set of taxa in a phylogenetic tree. We demonstrate the efficiency of these new algorithms by applying them to a set of 10,000 reasonable 5139-species mammal trees. This is the first time these indices have been computed on such a large taxon and we contrast our finding with an ad-hoc index for mammals, fair proportion (FP), used by the Zoological Society of London's EDGE programme. Our empirical results follow expectations. In particular, the Shapley values are very strongly correlat...

Plasma melatonin secretion rhythms in cattle under varying seasonal conditions
In conclusion, this study, which was the first to use spectral analysis to evaluate the cyclic rhythm of MEL in cattle, revealed that MEL secretion cycles did not differ among the seasons. These findings are inconsistent with previous study results in that previous reports suggested that the MEL secretion cycle differed under different lighting conditions.

Determination of GHG and ammonia emissions from stored dairy cattle slurry by using a floating dynamic chamber
ABSTRACT We developed a system for measuring emissions from stored slurry by using a floating dynamic chamber. CH4, CO2, N2O and NH3 emitted from the storage tank of a dairy cattle farm in eastern Hokkaido were measured during summer 2008 (7/16–8/6), fall 2008 (10/2–10/26), spring 2009 (6/2–6/21) and winter 2009 (3/11). Average daily gas emission rates in summer, fall and spring were, respectively, 54.8, 54.2 and 34.3 g/m2 for CH4; 602, 274 and 254 g/m2 for CO2; 55.4, 68.2 and trace mg/m2 for N2O; and 0.55, 0.73 and 0.46 g/m2 for NH3. CH4, CO2 and NH3 emission rates during the brief measurement period in winter were ...

Retrograde labeling and fine structure of olfactory receptor neurons in cat sharks.
Abstract Ciliated and microvillar olfactory receptor cells have been reported in many fish species, including teleosts and elasmobranchs. Morphological studies have suggested that microvillar cells are the only olfactory receptor cells in the elasmobranchs; however, there is no direct evidence for this hypothesis. Here we used a cat shark (Scyliorhinus torazame) to determine the cell type of the olfactory receptor cells in elasmobranchs. Retrograde labeling with a fluorescent dye, Dil, labeled only cells in the second layer from the surface of the olfactory epithelium, suggesting that ciliated cells located in the ...

Evolutionary Meaning of Non-Synchronous Medusa Release and Spawning in the Most Advanced Bivalve-Inhabiting Hydrozoan, Eugymnanthea japonica.
Abstract Circadial spawning times of medusa of the bivalve-inhabiting hydrozoans Eugymnanthea japonica Kubota and Eutima japonica Uchida are confirmed to be morning (possibly sunrise) for the former species and night for the latter. Eugymnanthea, with small, short-lived, univoltine medusae, seems to have evolved from a form similar to Eutima japonica, with larger, longer-lived, multivoltine medusae; the morning spawning of medusae in Eugymnanthea may therefore be a newly evolved trait. Medusa release from polyps and spawning of medusae are not synchronous in Eugymnanthea japonica. This non-synchrony may represent a...

Comparative Phylogeography of Two Crow Species: Jungle Crow Corvus macrorhynchos and Carrion Crow Corvus corone.
Abstract The jungle crow Corvus macrorhynchos Wagler, 1827, and the carrion crow Corvus corone L., 1758, are two closely related species with similar ecological requirements that occupy wide distribution ranges in the Palearctic. We studied patterns of their genetic variation by using sequences of the mitochondrial cytochrome b gene. Corvus macrorhynchos demonstrates a low level of variation and differentiation throughout its range, except for a highly diverged population of Cheju Island (Korea). The haplotype network shows two haplogroups. The island group comprises populations of Sakhalin, Hokkaido, Honshu, and K...

Prostaglandin e(2) increases both osteoblastic and osteoclastic activity in the scales and participates in calcium metabolism in goldfish.
zuki N Abstract Using our original in vitro assay system with goldfish scales, we examined the direct effect of prostaglandin E(2) (PGE(2)) on osteoclasts and osteoblasts in teleosts. In this assay system, we measured the activity of alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) as respective indicators of each activity in osteoblasts and osteoclasts. ALP activity in scales significantly increased following treatment at high concentration of PGE(2) (10(-7) and 10(-6) M) over 6 hrs of incubation. At 18 hrs of incubation, ALP activity also significantly increased in the PGE(2) (10(-9) to 1...

The inheritance of intrasexual dimorphism in female diving beetles (coleoptera: dytiscidae).
Abstract Many species of Dytiscus diving beetles exhibit intrasexual dimorphism, e.g., the elytra is smooth in some females and grooved in others. However, the expression of the grooves and whether they are a product of heredity or the environment remain unknown. One Japanese species, Dytiscus sharpi sharpi Wehncke, 1875 , also shows female dimorphism, with grooved and smooth morphs, while D. sharpi validus Régimbart, 1899, only has a single morph (the grooved type). A hybrid of the two species should therefore provide a means of sorting out how the grooves are inherited. We found two independent wetlands of D. sh...

The Repertoire of Chemical Defense Genes in the Coral Acropora digitifera Genome.
Abstract Scleractinian corals are of fundamental ecological significance in tropical and sub-tropical shallow water. This ecological success is attributed to their ability of formation of obligate endosymbioses with dinoflagellates of the genus Symbiodinium. Nevertheless, approximately one-third of reef-building coral species are critically endangered and the remainder are under threat from the effects of climate change and local impacts. Molecular and cellular mechanisms involved in stress responses and the establishment and collapse of the symbiosis are therefore an urgent subject of research. Metazoans possess l...

Cryptic diversity of the eel goby, genus taenioides (gobiidae: amblyopinae), in Japan.
Abstract The eel goby, genus Taenioides (Gobiidae: Amblyopinae), inhabits muddy bottoms of estuaries or shallow areas of seas in the Indo-Pacific Ocean. Among congeners, T. cirratus ( Blyth, 1860 ) has been thought to be distributed in Japan, but taxonomic confusions remain as to which scientific names are applicable to Japanese Taenioides species, or more fundamentally, how many Taenioides species are distributed in Japan, due in part to the rarity of this group in museum collections and the morphological similarity among species. To clarify the species diversity of the genus Taenioides in Japan, we conducted phyl...

Ovary structure and early oogenesis in the remipede, Godzilliognomus frondosus (Crustacea, Remipedia): phylogenetic implications.
Abstract Remipedia are enigmatic crustaceans of uncertain phylogenetic position with the general consensus that they are crucial for understanding the crustacean/arthropod evolution. It has been demonstrated previously that the features of the ovary organization and subcellular aspects of oogenesis are useful in resolving phylogenetic relationships in arthropods such as hexapods and onychophorans. The structure of the female gonads in Remipedia remains largely unknown; therefore, we examined the gross morphology and ultrastructural details of the ovary in a remipede, Godzilliognomus frondosus, with special emphasis...
