Histopathological Evaluation of the Exposure by Cyanobacteria Cultive Containing [d-Leu1]Microcystin-LR on Lithobates catesbeianus Tadpoles

open access: yesToxins, 2018
This study evaluated the effects of [d-Leu1]Microcystin-LR variant by the exposure of Lithobates catesbeianus tadpole to unialgal culture Microcystis aeruginosa NPLJ-4 strain.

Fluxes, moduli fixing and MSSM-like vacua in a simple IIA orientifold

open access: yes, 2005
We study the effects of adding RR, NS and metric fluxes on a T^6/(\Omega (-1)^{F_L} I_3) Type IIA orientifold. By using the effective flux-induced superpotential we obtain Minkowski or AdS vacua with broken or unbroken supersymmetry.

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Constraints on Low-Dimensional String Compactifications [PDF]

open access: yes, 1996
We study the restrictions imposed by cancellation of the tadpoles for two, three, and four-form gauge fields in string theory, M-theory and F-theory compactified to two, three and four dimensions, respectively.

Cervical Small Cell Neuroendocrine Carcinoma Initially Detected on Cytology: Diagnostic Pitfalls and Clues

open access: yesCytopathology, EarlyView.
This case describes the initial detection of cervical small cell neuroendocrine carcinoma on conventional endometrial and cervicovaginal liquid‐based cytology. Given its rarity and high aggressiveness, early recognition and rapid, intensive treatment are crucial for improving patient outcomes.

Poor biosecurity could lead to disease outbreaks in animal populations. [PDF]

open access: yesPLoS ONE, 2018
Human-mediated disease outbreaks due to poor biosecurity practices when processing animals in wild populations have been suspected. We tested whether not changing nitrile gloves between processing wood frog (Lithobates sylvaticus) tadpoles and co-housing

Star Formation in Tadpole Galaxies [PDF]

open access: yes, 2014
Tadpole Galaxies look like a star forming head with a tail structure to the side. They are also named cometaries. In a series of recent works we have discovered a number of issues that lead us to consider them extremely interesting targets.

The Effect of Heterospecific Song and Anthropogenic Sound on the Development of Life History Traits in a Field Cricket

open access: yesEthology, EarlyView.
We raised fall field crickets in acoustic environments of silence, their own song, traffic noise, or the song of the recently introduced Japanese burrowing cricket and measured development, size, and adult survival. We found that crickets reared with burrowing cricket song developed more quickly than crickets reared in silence.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ

open access: yesJournal of Anatomy, EarlyView.
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...
