Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II

The Anatomical Record, EarlyView.
Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

The Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

The Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

Reversion-inducing cysteine-rich protein with kazal motifs and matrix metalloproteinase-9 are prognostic markers in skull base chordomas [PDF]

, 2010
Prognosis of chordomas is difficult to predict based solely on histological findings. The purpose of this study was to assess expressions of reversion-inducing cysteine-rich protein with kazal motifs (RECK) and matrix metalloproteinase (MMP)-2, MMP-9 in ...

A man of his time: Joseph Leidy, racial science, and American anatomy

Anatomical Sciences Education, EarlyView.
Abstract Professor Joseph Leidy M.D. was arguably the most influential anatomist in the nineteenth‐century United States, having written over 500 publications and serving as the first President of the Association of American Anatomists. While many of Leidy's diverse contributions to American science and medicine are well‐known, scholars have said much ...

Delayed Wound Infection Associated with Bone Wax in Lateral Skull Base Surgery

, 2013
Background: Bone wax (Ethicon, Somerville, NJ) is a commonly used agent in neurotologic and skull base procedures. Its pliable nature makes it well suited for both hemostasis, especially for marrow-related bleeding, and obliteration of bony air cell ...

A biomechanical optimized Zr58Cu25Al14Nb3 bulk metallic glass dental implant improves peri‐implant stress distribution and bone quality under physiological loading

BMEMat, EarlyView.
This study reports a novel Zr58Cu25Al14Nb3 bulk metallic glass that possesses high mechanical strength and low elastic modulus, which further promotes efficient mechanotransduction and significantly improves peri‐implant bone quality upon cyclic occlusal loading.
