Analysis Of Skeletal Trauma: Examining Current And Potential, Maia Stevenson

D.U.Quark

Skeletal trauma is an important component of death investigations which is often discovered through postmortem computed tomography (PMCT) scanning. The analysis of skeletal trauma is a key process in the medicolegal field which could provide information on the cause and manner of death of the individual. Though PMCT provides useful imaging data for discovery, there is a lack of reliable technological tools for analyzation of such data. More definitive skeletal reconstruction tools and injury mechanism categorization tools would increase the efficiency of the post-mortem examination process. This review observes the current methods of discovering skeletal trauma through PMCT and surveys …

Numerical Variations In The Thoracic And Lumbar Vertebrae Within The John A. Williams Skeletal Collection, Western Carolina University, Cullowhee, Nc (Usa), Leanna Annette Sanford

Department of Anthropology: Theses and Student Research

This research is on how human variation can lead to the identification of remains based on skeletal variation. The data were collected by performing a morphoscopic trait study of the John A. Williams (J.A.W.) Documented Human Skeletal Collection at Western Carolina University in Cullowhee, NC (USA). Morphoscopic traits are nonmetric traits, visually identified using the knowledge of osteology. The study was performed to study variation of the vertebral column, specifically focusing on morphoscopic traits of the thoracic and lumbar vertebrae. The focus of this research is centralized on the presence of numerical variations in the vertebral column such as eleven …

The Osteobiography Of Human Remains From The Seaview And Indian Town Trail Archaeological Sites, Maggie M. Klemm

Department of Anthropology: Theses and Student Research

Extensive site surveys and excavations on the Island of Barbuda led by Sophia Perdikaris have identified over 62 sites spanning from the Archaic time period to Historic times. Over the last 18 years, these multidisciplinary teams have focused on mapping all sites and performing rescue excavations on sites threatened by sea level rise, erosion or development. Two such sites are the Saladoid site of Seaview (BA016) and the Troumassoid site of Indian Town Trail (BA01). The dunes surrounding the site of Seaview receive the brunt of storms and hurricanes. In 1998 hurricane Georges exposed skeletal material now part of the …

The Development And Evaluation Of A Method For Complete Collagenase I Digestion Of Bos Taurus Bone Samples, Reilly Price

Master of Science in Forensic Science Directed Research Projects

Current methods for processing aged forensic bone samples for DNA analysis involve pulverization and organic extraction, which further destroys already degraded DNA and uses large amounts of limited samples. Additionally, the success rates for this type of analysis vary widely as homogenization incorporates PCR inhibitors into the sample. Little research has explored how pulverization results in DNA damage in profiles obtained from skeletal remains. This study proposes an enzymatic digestion method to separate osteocytes from PCR inhibitors in the extracellular bone matrix to improve the quality and quantity of DNA isolated from aged bone samples. The technique described here used …

Comparison Of Hydrolysis Efficiency And Performance Of Four Recombinant Β- Glucuronidase Enzymes For The Detection Of Opioids In Urine Samples By Lc-Ms/Ms, Christina Fernandez

Student Theses

The United States has been experiencing a nationwide public health crisis since introducing prescription opioids in the 1990s. A central problem with opioids is their highly addictive nature causing a dose-dependent respiratory depression leading to overdoses and deaths. Drug overdose deaths have risen in the past two decades, with opioids being the dominant driver of this epidemic. Given the circumstances, accurate and efficient confirmatory analysis of opioids in urine is essential to monitoring patients’ compliance and preventing drug diversion in clinical and forensic settings. The development of recombinant β-glucuronidases allows for the hydrolysis of glucuronidated opioids using a shorter incubation …

Ohio Forensic Nurse Examiners: Readiness To Care For Victims Of Sexual Assault With Disability, Deanna Nicole Smith

Doctor of Nursing Practice Scholarly Projects

Forensic nurse examiners (FNEs) care for crime victims in acute care settings. These nurses are specifically trained in trauma-informed care and evidence collection in cases of sexual assault, domestic violence, abuse, and human trafficking (RAINN, 2022). The scholarly project focuses on the care of victims of sexual assault living with disability, as this population is three times more likely to be victimized than any other population (NSVRC, 2022). The project literature review reveals a lack of data on preparation standards for FNEs on caring for victims with disability and providing accommodations during forensic examination. Currently, it is unknown if FNEs …

Elisa Validation Method For The Detection Of Ketamine In Hair, Daria A. Centonza

Student Theses

An ELISA method was developed and validated to detect ketamine in human hair samples. Ketamine is an anesthetic drug that causes memory loss, dissociative sensations, and hallucinations. Due to these adverse effects, ketamine is a common drug used in drug facilitated sexual assaults (DFSAs). It is very important to be able to detect the substances used in DFSAs over a longer period of time due to the delayed reporting of these crimes. Victims, often out of fear and from the sedative/memory loss effects of the drugs, tend to report these crimes when it is too late to use urine and …

Development Of A Non-Invasive Dna Extraction Method From Teeth, Monalisa Heng

Honors Theses

Forensic dentistry has evolved from simple morphological investigations to genetic and molecular analysis. One of the most important techniques is DNA analysis which requires viable samples from an individual or crime site. The orofacial region can be a good source for DNA samples because the tissues can resist environmental, thermal, electrical, and mechanical challenges. Teeth are especially useful as a source of genetic material because the DNA located in the pulp is surrounded by protective mineral tissue. The DNA in the pulp tissue is currently accessed through destructive methods involving crushing, pulverization, and splitting the tooth. Unfortunately, destructive methods destroy …

Core Point Pixel-Level Localization By Fingerprint Features In Spatial Domain, Xueyi Ye, Yuzhong Shen, Maosheng Zeng, Yirui Liu, Huahua Chen, Zhijing Zhao

Computational Modeling & Simulation Engineering Faculty Publications

Singular point detection is a primary step in fingerprint recognition, especially for fingerprint alignment and classification. But in present there are still some problems and challenges such as more false-positive singular points or inaccurate reference point localization. This paper proposes an accurate core point localization method based on spatial domain features of fingerprint images from a completely different viewpoint to improve the fingerprint core point displacement problem of singular point detection. The method first defines new fingerprint features, called furcation and confluence, to represent specific ridge/valley distribution in a core point area, and uses them to extract the innermost Curve …

Pain That Only She Must Bear: On The Invisibility Of Women In Judicial Abortion Rhetoric, Francesca Laguardia

Department of Justice Studies Faculty Scholarship and Creative Works

The graphic and bodily facts of a legal question of rights are relevant to the courts, particularly in questions that directly implicate physical bodies and pain, such as right to die cases, or what level of search may be allowable and when. However, in the case of abortion, or more specifically the bodily ramifications of pregnancy and childbirth, this detail is conspicuously absent. This article, relying on a content analysis of over 220 legal opinions on abortion rights, documents this absence of rhetoric. Particularly in the context of other discussions of pain and physical health risks in these very same …

Investigation Of Postmortem Methamphetamine Cases Submitted To The New York City Office Of Chief Medical Examiner, Isaiah Jewell

Student Theses

Methamphetamine (N-methylamphetamine) is a central nervous system stimulant (CNS) and sympathomimetic drug with a high addiction potential. In the United States, there has been a significant increase in the presence of methamphetamine in recent years, specifically in the Northeastern region of the country. The New York City Office of Chief Medical Examiner (NYC-OCME) postmortem methamphetamine casework from 2018 and 2019 was analyzed and revealed that the presence of the drug increased drastically within a span of one year, jumping from 65 cases in 2018 to 99 cases in 2019. Males were overwhelmingly responsible for much of the casework, taking up …

The Absence Or Misuse Of Statistics In Forensic Science As A Contributor To Wrongful Convictions: From Pattern Matching To Medical Opinions About Child Abuse, Keith A. Findley

Dickinson Law Review (2017-Present)

The new scrutiny that has been applied to the forensic sciences since the emergence of DNA profiling as the gold standard three decades ago has identified numerous concerns about the absence of a solid scientific footing for most disciplines. This article examines one of the lesser-considered problems that afflicts virtually all of the pattern-matching (or “individualization”) disciplines (largely apart from DNA), and even undermines the validity of other forensic disciplines like forensic pathology and medical determinations about child abuse, particularly Shaken Baby Syndrome/Abusive Head Trauma (SBS/AHT). That problem is the absence or misuse of statistics. This article begins by applying …

Pornography: Social, Emotional And Mental Implications Among Adolescents, William Kelly Canady

National Youth Advocacy & Resilience Conference

This presentation will explain the historical development of pornography. It will highlight four segments: 1- Porn’s impact on brain development of reward pathways, ultimately increasing the appetite for more porn. 2- Porn can be a false substitute for real intimacy, resulting in decreased sexual satisfaction with a real person and increased verbal and physical aggression. 3- Porn promotes sex trafficking, promotes multiple sex partners and reduced STD prevention. 4- A review of interventions available to assist clients in navigating a lifestyle away from pornography.

Extracellular vesicles (EVs) shuttle microRNA (miRNA) throughout the circulation and are believed to represent a fingerprint of the releasing cell. We isolated and characterized serum EVs of breast tumour-bearing animals, breast cancer (BC) patients, and healthy controls. EVs were characterized using transmission electron microscopy (TEM), protein quantification, western blotting, and nanoparticle tracking analysis (NTA). Absolute quantitative (AQ)-PCR was employed to analyse EV-miR-451a expression. Isolated EVs had the appropriate morphology and size. Patient sera contained significantly more EVs than did healthy controls. In tumour-bearing animals, a correlation between serum EV number and tumour burden was observed. There was no significant relationship …
