The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

OBSERVATIONS ON STRUCTURAL FEATURES AND CHARACTERISTICS OF BIOLOGICAL APATITE CRYSTALS: 4. OBSERVATION ON ULTRASTRUCTURE OF HUMAN BONE CRYSTALS

open access: yes, 1993
In a series of studies to investigate the structural features of the biological crystals such as the tooth and bone, following the previous observations of the tooth crystal using an electron microscope, we examined the ultrastructure of the human bone ...

Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

open access: yesThe Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Influence of decalcification procedures on immunohistochemistry and molecular pathology in breast cancer

open access: yes, 2016
Distant breast cancer metastases are nowadays routinely biopsied to reassess receptor status and to isolate DNA for sequencing of druggable targets. Bone metastases are the most frequent subgroup.

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK Pathways

open access: yesArthritis &Rheumatology, EarlyView.
Objective Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

Positional Relationship Between the Orbicularis Oculi and Zygomaticus Complex Muscles by Ultrasonography: New Anatomical Insights for Crow's Feet Injection

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The orbicularis oculi muscle (OOc) is strongly associated with facial aging as its contraction causes the formation of crow's feet. Botulinum neurotoxin (BoNT) injection is a representative treatment targeting muscle. The aim of this study was to demonstrate the anatomical relationship between the OOc and the zygomaticus complex muscles, and ...

Influence of various factors on decalcification time of bone tissue samples

open access: yes, 2023
Kosti dajejo našemu telesu oporo, varujejo notranje organe ter so zaloga kalcijevih in fosforjevih ionov. V histopatološkem laboratoriju so vzorci kostnega tkiva podvrženi dekalcinaciji, saj ta omogoči njihovo zmehčanje.

Histopathologic Analysis of the Morpho‐Functional Zones of the Human Acetabular Labrum

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The structural and functional adaptation of soft tissues to mechanical load controls their ability to withstand injury and influences their capacity for healing. Similar to the knee meniscus, the acetabular labrum exhibits zonal differences in mechanical load distribution, resulting in distinct regions with unique structural and functional ...

New Insights Into the Anconeus Epitrochlearis Muscle and Its Relationship to the Ulnar Nerve: Anatomical Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Ulnar neuropathy due to compression at the cubital tunnel is common. However, our understanding of the relationships between this type of nerve compression and the variant anconeus epitrochlearis muscle (AEM) is poorly understood. Therefore, the present anatomical study was performed to better elucidate these relationships.
