Corneal curvatures and refractions of Central American anurans

, 1997
We employed neutralizing infrared videophotorefraction and photokeratometry to examine the manifest refractions and corneal curvatures of 21 species of anurans (frogs and toads) in five families (Dendrobatidae, Bufonidae, Centrolenidae, Leptodactylidae ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

The Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

ANK1 and EPB41 Variants and The Risk of Glucocorticoid‐Induced Osteonecrosis

Arthritis &Rheumatology, EarlyView.
Objective Steroid‐induced osteonecrosis of the femoral head (SONFH) is a refractory skeletal disorder influenced by genetic and environmental factors. However, conclusive pathogenic genetic evidence remains elusive due to the limited exploration of rare damaging variants. In this study, we aimed to identify rare variants associated with SONFH.

Ammonia as a Pheromone in Anuran Tadpoles

Physiological Research, 2011
In laboratory experiments, conspecific excretions and ammonia solutions evoked avoidance reactions in tadpoles of three anuran species, Bufo bufo, Rana temporaria, and Rana arvalis. A differential sensitivity of ammonia chemoreception was determined for two anuran species.

Targeting Amastigote and Trypomastigote Phases: Multi‐Epitope Vaccine Strategy Against Trypanosoma cruzi

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Effective vaccines against Trypanosoma cruzi, the causative agent of Chagas disease, are urgently needed. Here, we report the design and in silico validation of a novel multiepitope vaccine construct targeting the key surface proteins ASP‐2 and gp82. Using a comprehensive immunoinformatics pipeline, we identified and selected 38 potent T‐cell (

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

British Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.

Variation in Southeast Asian anurans [PDF]

, 2008
This dissertation reports studies of variation in Southeast Asian frog species as it affects their ability to respond to environmental change. First, using museum specimens of Bornean anurans, I found that clutch size did not increase with altitude, as ...

Lethal and Sublethal Effects of Glyphosate (Roundup® Active) to Embryos of Colombian Anurans

Acta Biológica Colombiana, 2013
Glyphosate is an herbicide widely used in agriculture, which may affect non-target species. The aim of this study was to determine the lethal (Median lethal concentration - LC50) and sublethal effects (changes on body size and development) of glyphosate (
