Neonatal exposure to diethylstilbestrol leads to impaired action of androgens in adult male hamsters
(Elsevier, 2004-11)Neonatal treatment with diethylstilbestrol (DES) leads to disruption of spermatogenesis in adult animals after apparently normal testicular development during puberty indicating aberrant androgen action in DES-exposed adult ... -
A new cryptic species and review of the east-Andean leaf chafer genus Mesomerodon Ohaus, 1905 (Coleoptera, Scarabaeidae, Rutelinae)
(Pensoft Publishers, 2017-04-26)The Neotropical scarab beetle genus Mesomerodon Ohaus (Scarabaeidae: Rutelinae: Rutelini) is distributed in the western (lowland) Amazonian region from Colombia to Bolivia. Based on our research, the genus includes three ... -
New Nebraska occurrences of the endangered American burying Beetle (Coleoptera: Silphidae)
(The Coleopterists Society, 1992-12)Six new records for the endangered American burying beetle, Nicrophorus americanus Olivier, are reported from the Nebraska Sandhills. Nebraska is one of only four states in the United States where this beetle remains extant. -

(Pensoft Publishers, 2022-10-17)The phytophagous scarab genus Macraspis MacLeay (Scarabaeidae, Rutelinae, Rutelini) is reviewed from the Brazilian Amazon region. Three new species are described and illustrated from the states of Amazonas, Pará, and ... -
A new species of Parachrysina Bates (Coleoptera: Scarabaeidae: Rutelinae) from Nuevo León, Mexico
(The Coleopterists Society, 1991-09)Parachrysina borealis is described as new, and a revised key to the species is provided. Parachrysina borealis represents the northernmost extent of the genus and is the only species of Areodina known from northeastern Mexico. -
A new species of Pelidnota (Coleoptera: Scarabaeidae: Rutelinae) from Panama
(The Coleopterists Society, 1989-09)Pelidnotah irsutiphallica new species, is described as new from Colón and Bocas del Toro provinces in Panama. It is incorporated into the most recent key to the genus and distinguished from its congeners. -
A new species of Viridimicus Jameson from Honduras (Scarabaeidae: Rutelinae)
(The Coleopterists Society, 1999)Viridimicus omoaensis Jameson is described from Honduras. This species extends the distribution of the genus from Guatemala southwards in Mesoamerica. The characters that define the genus are expanded to include V. ... -
Next-generation sampling: pairing genomics with herbarium specimens provides species-level signal in solidago (asteraceae)
(Botanical Society of America, 2015-06)Premise of the study: The ability to conduct species delimitation and phylogeny reconstruction with genomic data sets obtained exclusively from herbarium specimens would rapidly enhance our knowledge of large, taxonomically ... -
Nitrogen-fixation activity and the abundance and taxonomy of nifH genes in agricultural, pristine, and urban prairie stream sediments chronically exposed to different levels of nitrogen loading
(Springer Berlin Heidelberg, 2018-05)Small streams exert great influences on the retention and attenuation of nitrogen (N) within stream networks. Human land use can lead to increased transport of dissolved inorganic N compounds and downstream eutrophication. ... -
No free refills: Prior drying and vertebrate colonisation alter ecological functioning and vertebrate fitness within experimental aquatic systems
(John Wiley and Sons Inc, 2023-07-21)1. Intermittent streams are hydrologically dynamic within and among years, leading to episodic bouts of local extirpations and subsequent recolonization of vertebrate groups such as fish and larval amphibians. As these ... -
No interaction between competition and herbivory in limiting introduced Cirsium vulgare rosette growth and reproduction
(Springer, 2009-08)Both competition and herbivory have been shown to reduce plant survival, growth, and reproduction. Much less is known about whether competition and herbivory interact in determining plant performance, especially for ... -

Novel dual inhibitors of vascular endothelial growth factor and VEGFR2 receptor
(Wiley-Blackwell, 2012-10)Eur J Clin Invest 2012; 42 (10): 10611067 Abstract Background Vascular endothelial growth factor (VEGF) helps control tumour growth via causing new capillaries growth in tumours. Four cardiac hormones [i.e. vessel dilator, ... -
The occurrence and regional distribution of DR4 on herniated disc cells: a potential apoptosis pathway in lumbar intervertebral disc
(Lippincott, Williams & Wilkins, 2008-02-15)Study Design. Intervertebral discs surgically obtained from 60 herniated patients and 5 normal individuals were examined to correlate the regional distribution of DR4-receptor and apoptosis. Objective. To explore the ... -
Oligosaccharide mapping reveals hormone-specific glycosylation patterns on equine gonadotropin alpha-subunit Asn56
(The Endocrine Society, 1996-06)Equine gonadotropin alpha-subunit glycosylation was examined by releasing oligosaccharides using a sequential enzymatic deglycosylation protocol and comparing the released oligosaccharide populations using a high resolution ... -
Oxidative cell damage in Kat-sod assay of oxyhalides as inorganic disinfection by-products and their occurrence by ozonation
(Springer New York, 2000-01)Nine oxyhalides as possible inorganic disinfection by-products were tested for oxidative cell damage by Kat-sod assay with E. coli mutant strains deficient in the active oxygen-scavenging enzymes. Chlorine dioxide, chlorite, ... -
Oxidative stress in phenylketonuria animal model
(PubMed, 2002-05)Oxidative stress is seen in various metabolic disorders for unknown reasons. Oxidative stress is defined as an imbalance between pro-oxidant and antioxidant status in favor of the former. This study investigated whether ... -
Pahhph-5: a mouse mutant deficient in phenylalanine hydroxylase
