Background: Stature is an important indicator for identification like other phenotypic traits; it is determined by a combination of genetic and environmental factors. Stature or body height is one of the most important and useful anthropometric parameters that determine the physical identity of an individual, it is also considered as one of the important and significant parameters for the establishment of personal identity in the forensic medical examination or anthropological studies, particularly with the alarming increase in the frequency of road, floods, deliberate mutilation, and natural disasters.
Objectives: To predict stature and sex from the percutaneous length of arm and forearm bones in an adult Nigeria population.
Methods: The sample group used for this research consists of staff, students, and volunteers from the University of Lagos, comprising 222 individuals (115 males and 107 females) aged between 18-65 years. Various anthropological instruments such as Stadiometer: a product of SECA alpha® model 770, Germany, anthropometric Tape: calibrated in centimeters, weighing balance, and caliper were used for taking the measurement.
Results and Conclusion: Logistic regression showed statistical significance in sex prediction with the highest value gotten from the intercondylar width. All parameters showed a positive correlation with stature with the strongest from ulnar while the weakest was in the intercondylar measurement. Percutaneous measurement of arm and forearm length of both males and females provides good reliability in the estimation of stature and predicting of sex. Sexual dimorphism correlates more with the intercondylar. Simple and multiple linear regressions proved that the best way to predict and estimate stature is by taking the foot length.

Nanotechnology acts as a powerful classical tool for the purpose of identification, individualization and evaluation of materials with evidentiary value. The novel properties introduced by the changes in physical and chemical properties of the material are utilized for the forensic purposes in the detection of latent fingerprints, drugs, explosive materials etc. Nanomaterials area also proved to enhance the PCR efficiency and thereby benefits the DNA analysis. The nano-based analytical equipments such as Atomic Force Microscopy (AFM), Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS), Raman Micro spectroscopy and Time of Flight mass Spectroscopy (TOF-MS) are utilized for the visualization and the detection of evidences of trace amount. Among these, AFM possess wide range of applications in Forensic applications in a variety of fields such as determination of sequence of strokes, time since death, age of bloodstain etc and therefore focused in this paper, along with other nanoparticles applications.

In the mid 1980s, forensic DNA testing has been introduced It has played a very comprehensive role in providing service to the mankind via race finding, population determination, cast analysis, parental lineage, declaring punishment to the culprit and providing relief to the innocent. Remains of the victims of the mass disasters and of the missing people have been recombined for the identification purpose through linking them with the reference samples. The advancement of the new technologies have enhanced the capabilities of the laboratories working in recovering DNA results with more accuracy and improved sensitivity. Forensic laboratories have fully adopted automation for the sample preparation and for data analysis in order to provide efficient results. In forensic DNA analysis Short Tandem Repeat (STR) typing continues to be the most dependable and durable one although other genetic markers are also available and used for specific purposes.
