Bone mineral density (BMD) is an important factor in understanding nutritional intake. For human skeletal remains, it is a useful metric to assess quality of life in both juveniles and adults, particularly in fatal starvation and neglect cases. This paper provides guidelines for scanning human skeletal remains for forensic purposes.

To assess the in vivo effects of therapeutic interventions for muscle disease, methods are needed to quantitate force generation and fatigability in treated muscle. We detail an approach to evaluating myo-mechanical properties in explanted mouse hindlimb muscle. This analysis provides a robust approach to quantitating the effects of genetic modification on muscle function, as well as comparison of therapies in mouse models of muscle disease.

Zebrafish are an emerging system for modeling human disorders of the skeletal muscle. We describe a fast and efficient method to isolate skeletal muscle myofibers from embryonic and larval zebrafish. This method yields a high-density myofiber preparation suitable for study of single skeletal muscle fiber morphology, protein subcellular localization, and muscle physiology.

The zebrafish is now an established and powerful tool for modeling muscular dystrophies, congenital myopathies, and related neuromuscular diseases. Birefringence and touch-evoked escape behavior are two common noninvasive assays used to determine the degree of muscular disorganization and locomotive impairment of zebrafish embryos during early development.

Immunohistochemical staining of myosin heavy chain isoforms has emerged as the state-of-the-art discriminator of skeletal muscle fiber-type (i.e., type I, type IIA, type IIX, type IIB). Here, we present a staining protocol along with a novel semi-automated algorithm that facilitates rapid assessment of fiber-type and fiber morphology.
FAQs
Bone morphology, measurements, microscopic structure, damage, and chemical or genetic signals contribute different kinds of biological evidence. Morphology describes form, measurements provide quantitative comparisons, and microscopy examines structure at a smaller scale. Damage records physical alteration, while chemical or genetic signals add additional evidence. Considering them together supports estimates of age, stature, population affinity, species, and trauma.
Taphonomic interpretation helps determine whether observed damage reflects activity-related change or postmortem alteration. Decomposition and environmental conditions can modify bones and teeth after soft tissues decay, potentially changing the evidence available for analysis. By considering those influences alongside the recorded damage, investigators can avoid treating every alteration as evidence of events during life or at death.
Species identification and population-affinity assessment are related but distinct goals. Species concerns which biological group the remains represent, whereas population affinity addresses patterns of biological variation within the examined material. Skeletal morphology, measurements, microscopic structure, and chemical or genetic signals may contribute to these interpretations, allowing biology, zoology, archaeology, and forensic work to ask different questions of the same evidence.
Age and stature are estimates rather than direct readings from a skeleton. Analysts derive them from observable biological evidence, including bone and tooth morphology, measurements, and microscopic structure, while recognizing that decomposition and environmental alteration may affect what remains available. This makes careful documentation and evidence-based interpretation important when reconstructing biological characteristics from altered material.
A basic workflow begins with examining the available bones and teeth, then documenting morphology, taking measurements, assessing microscopic structure, and recording visible damage. Where supported by the material, chemical or genetic signals can add another line of evidence. The analysis must also account for decomposition and environmental alteration so observations are interpreted in relation to preservation conditions.
Archaeologists can use the findings to investigate biological variation and aspects of past lives, while forensic investigators can apply them to biological characteristics, trauma, and death circumstances. Zoological studies may focus on species-level interpretation. The same evidence therefore supports different applications, but its meaning depends on the question and the context in which remains are examined.
In biology, the method connects anatomy with taphonomy and evidence-based interpretation. Anatomical observations describe the form and structure preserved in bones and teeth, whereas taphonomic considerations address decomposition and environmental alteration. This connection helps researchers separate biological variation from changes produced after death, supporting reconstructions of past lives, death circumstances, and variation among biological groups.
