Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

The acute Toxicological effects of Gammalin 20 on the lung and Pancreas of Guinea Pig

Journal of Applied Sciences and Environmental Management, 2005
The acute toxicological effects of Gammalin 20 (gamma Isomer of hexachlorocyclohexane) on the lungs and Pancreas of Guinea Pig were investigated. Twenty-Eight Guinea Pigs of 300gm average body wt were used for the study.

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part II Deriving instrument‐specific correction equations for meta‐analyses using published data

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin‐D28k, parvalbumin, glial fibrillary acidic protein, and Iba‐1 during pre‐hibernation and hibernation

The Anatomical Record, EarlyView.
Abstract Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of Spermophilus xanthoprymnus during pre‐hibernation and hibernation periods using immunohistochemical ...

Effects of Tegaserod on Ileal Peristalsis of Guinea Pig In Vitro

Journal of Pharmacological Sciences, 2004
The mechanisms of prokinetic action of tegaserod in the gastrointestinal tract has not been studied in detail. The aim of this study was to investigate the effect of tegaserod on peristaltic reflexes and propagating peristaltic waves in guinea pig ileum.

Isolation of a peptide in guinea pig liver homogenate and its turnover of leucine [PDF]

, 1948
Leucine was synthesized with C14 in the carboxyl group. 10 mg. of the radioactive amino acid (DL) and 0.66 gm. (wet weight) of guinea pig liver homogenate were added to a reaction mixture containing 1.3 per cent of an amino acid mixture corresponding to ...

Inter‐microscope comparability of dental microwear texture data obtained from different optical profilometers: Part I Reproducibility of diet inference using different instruments

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

The effects of diet on anatomy, physiology and health in the guinea pig [PDF]

, 2017
Given the increasing popularity of the guinea pig as a pet, it is perhaps surprising that relatively little is published as to their husbandry and dietary requirements.

The role of external broadcasting in a closed political system [PDF]

, 2011
This article investigates the role and impact of external broadcasting (radio and television) on a closed political system, through the example of the two post-war German states: the West German Federal Republic of Germany (FRG) and the East German ...
