Analogs of Ridge Skin and Papillary Patterns in the Nature and the Significance of Their Study for Forensic Science and Forensic Examination

Patterns similar to the papillary patterns of human fingers, palms, and soles can be found in living and inanimate nature. Studying such patterns and the structure of the ridged skin of humans and primates in comparison with similar formations on other objects is necessary for forensic science, forensic traceology, fingerprinting, and biometric identification. The article analyzes the history of the study of the ridged skin of humans, primates, and other animals by forensic scientists, zoologists, anthropologists, and representatives of other sciences.The author proposes systemizing and classifying the information about the analogs of papillary patterns and ridged skin on such grounds as the genus and type of carrier objects, relief structure, degree of comparability with the papillary pattern of human hands and soles.The article presents the most indicative varieties of analogs of papillary patterns in mammals, birds, fish, insects, corals, plants, and fungi. The author has studied and systemized structural features of the striped pattern of the skin of tigers and zebras, crests and stripes in corals, stripes and ridged patterns in fish. The data obtained on ridge formations, which are similar in structure and shape to the papillary patterns of human fingers and palms, will help to avoid expert errors during fingerprinting examination or erroneous placement of images of such formations in forensic databases.Knowledge of the structural features and properties of striped patterns of skins of specially protected wild animals, as well as the crest surface of paleontological museum objects, should be used for their identification by photo and video images in cases of embezzlement, smuggling, illegal hunting, and illegal trafficking.

Modern Classification of the Properties of Papillary Patterns of Human Hands and Feet for the Solution of Identification and Non-Identification Problems in Forensic Expert Activities

The relevance and novelty of the topic of the article is connected with the fact that for the first time the improved classification of the properties of human papillary patterns and their displays and the dynamic trend of expanding the legal base of fingerprint registration in the world are considered. The goal is to systematize the properties of human papillary patterns and their representations. General scientific and special methods were used. The analysis of the literature and the author's practice allow us to identify and consider the following properties of papillary patterns and their mappings, which were divided into three groups for cognitive purposes: their own properties, the properties of mappings, and the properties of the fat-rich substance of the human papillary pattern and its trace. For the first time, the properties of the poly-fat substance of the human papillary pattern and its trace are presented, which is important in view of the trend in the development of complex fingerprint examination. For the first time, the first and second groups are conditionally divided into four subgroups: for solving identification, diagnostic, classification and situational problems. For the first time, the third group is further conditionally divided into four subgroups: according to the interaction of the human body fat with the carrier object; according to the isolation of the human body fat trace; according to the dynamics of the preservation and contrast of the display of the fat-free substance of the human papillary pattern. On the other hand, the properties of papillary patterns themselves are divided into basic properties and properties for solving identification and non-identification problems, respectively. The author's definition of the following concepts is presented: "basic properties of human papillary patterns" and "properties of human papillary patterns", "basic properties of human papillary patterns mappings" and "properties of human papillary patterns mappings", "basic properties of human papillary matter" and "properties of human papillary matter", "basic properties of human papillary matter" and" properties of human papillary matter". This provides an opportunity for specialists and teachers to improve their cognitive and practical activities, and for those responsible and competent for the organization of examinations to consider creating a center for comprehensive fingerprint examination.

Comparative Study on Frequency of Various Papillary Pattern Types in Estonian Men and Women

The authors of the article conducted a comparative study to determine the incidence frequency of various papillary patterns in men and women. In the framework of this study, the authors collected and performed analysis on data published in the subject literature. Comparative analysis was performed to check for potential similarities and differences in papillary patterns, types, and groups in men and women, using data on the patterns in both hands. This article presents the results of the study.

Fingerprint analysis (AFIS) and biometric system of identification by fingerprints: issue of artificial papillary pictures

The article discusses the theoretical and applied aspects, as well as prospects for the development of fingerprint examination, fingerprint records (automated fingerprint identification systems-AFIS) in the disclosure and uncovering of crimes, as well as biometric identification systems by fingerprints to protect personal data, control access to corporate and personal information, time tracking in the information sector of the economy. The paper presents methods form an ufacturing models with artificial papillary patterns (falsification of papillary patterns of fingerprints), the results of experiments that consisted in creating a model (dummy) of the nail phalanx of the finger with an artificial papillary pattern and verification of a biometric scanner using biometric technologies.

Axillary Nodal Metastasis with Papillary Morphology: An Uncommon Origin

<b><i>Background:</i></b> Metastases to axillary lymph nodes are commonly and readily confirmed by fine needle aspiration cytology (FNAC). Most likely, these arise from breast primaries. However, the diagnosis can become complicated when unusual cytomorphology is encountered. <b><i>Case:</i></b> We report a 60-year-old woman presenting with bilateral axillary lymphadenopathies but without breast lesions. History showed increasing CA-125 levels. FNAC yielded carcinoma cells showing prominent papillary pattern, being composed of mild to moderately differentiated malignant cells, with focal abortive glandular formation and squamous metaplasia. IHC stains were done and the tumor cells were PAX-8 positive, but GATA-3 and GCDFP-15 negative. Coupled with the clinical history, a diagnosis of metastatic endometrioid adenocarcinoma was made. <b><i>Conclusion:</i></b> Nodal metastases with papillary cytomorphology can rarely arise from nonbreast primaries. The presence of papillary pattern, particularly in the absence of a clinically detectable breast lesion, should raise the possibility of a metastasis. Correlation with patient history, imaging findings and judicious use of IHC studies are crucial for a correct diagnosis.
