BACKGROUND: Prostatic enlargement was first correctly recognized as a prostatic hyperplasia by professor of anatomic pathology, Stanisław Ciechanowski (1869-1945) in Cracow on contrary to Parisian urologist Jean Casimir Félix Guyon's concepts of progressing atherosclerosis as a morphological cause of prostatic overgrowth and mechanical insufficiency of lower urinary tract. METHODS: Primary resources were analyzed about Stanisław Ciechanowski mainly from depositories of the Section of Special Collection, Stanisław Konopka Main Medical Library Warsaw and Polish bibliograhy of Estreichers at Jagiellonian University...

BACKGROUND: The anatomic variations of the visceral arteries are not uncommon. The liver arterial blood supply shows 50% variability between humans, with the most common anatomy being one hepatic artery arising from the celiac trunk and one pancreatico-duodenal arcade between the celiac trunk and the superior mesenteric artery. Occlusion of one artery are mostly asymptomatic but may become clinically relevant when surgery of the liver, bile duct or the pancreas is required. If these pathologies are not reversible, an oncologic pancreatic head resection cannot be performed...

Many Anglo-American universities have undertaken a paradigm shift in how the dissection of human material is approached, such that students are encouraged to learn about the lives of body donors, and to respectfully "personalize" them as human beings, rather than treating the specimens as anonymous cadavers. For the purposes of this study, this provision of limited personal information regarding the life of a body donor will be referred to as "personalization" of body donors. At this time, it is unknown whether this paradigm shift in the personalization of body donors can be translated into the German-speaking world...

This article presents a hitherto unknown memorandum authored by Kurt Gerstein, the Confessing Church's resistance fighter and witness to the Holocaust. In this memorandum, submitted to the Reich Ministry of the Interior in April 1938, Gerstein deals extensively with the contemporary system of anatomical body procurement, its roots and predicaments. Putting the memorandum into the wider context of his discordant life allows a gap to be closed in Gerstein's biography, whereby his relationship with medicine presented a means of moral reorientation between a Christian requirement and the National Socialist reality...

Twice in fifteen months the popular press has published reports of the discovery of a new human organ. The claims that the mesentery and interstitium are organs come from medical practitioners, not from anatomical scientists. Although both of these anatomical entities are important in the functioning of the body, neither satisfies the requirements that an organ be composed of two or more tissues and perform a special function. Also missing, in the recent claim that the interstitium, that is, connective tissues with fluid-filled spaces, is an organ, is a statement to that effect in the original research report...

Phantoms simulating the human body play a central role in radiation dosimetry. The first computational body phantoms were based upon mathematical expressions describing idealised body organs. With the advent of more powerful computers in the 1980s, voxel phantoms have been developed. Being based on three-dimensional images of individuals, they offer a more realistic anatomy. Hence, the International Commission on Radiological Protection (ICRP) decided to construct voxel phantoms representative of the adult Reference Male and Reference Female for the update of organ dose coefficients...

Both in mainland China and around the world, regional anatomy stands as one of the most important basic science courses in medical school curricula. As such, dissection of human cadavers and use of prosected specimens remains the most essential teaching method in anatomy education. However, medical educators have raised increasing concerns about an ongoing shortage of cadavers for medical use in mainland China, a problem which may seriously limit the future development of human anatomy education. Based on a survey on cadaver usage in anatomy education in mainland China, this study found that the cadaver resources of most given medical schools in mainland China are associated with their geographic location, academic ranking, and local support for body donation policies...

Epidemiological investigation is an important approach to assessing the risk of late effects after radiotherapy, and organ dosimetry is a crucial part of such analysis. Computed tomography (CT) images, if available, can be a valuable resource for individualizing the dosimetry, because they describe the specific anatomy of the patient. However, CT images acquired for radiation treatment planning purposes cover only a portion of the body near the target volume, whereas for epidemiology, the interest lies in the more distant normal tissues, which may be located outside the scan range...

PURPOSE: Pancreatic cancer is the fourth cause of death by cancer worldwide. Lymph node (LN) involvement is known to be the main prognostic factor. However, lymphatic anatomy is complex and only partially characterized. The aim of the study was to study the pancreatic lymphatic system using computer-assisted anatomic dissection (CAAD) technique and also to update CAAD technique by automatizing slice alignment. METHODS: We dissected three human fetuses aged from 18 to 34 WA...

The mammillary bodies as part of the hypothalamic nuclei are in the central limbic circuitry of the human brain. The mammillary bodies are shown to be directly or indirectly connected to the amygdala, hippocampus, and thalami as the major gray matter structures of the human limbic system. Although it is not primarily considered as part of the human limbic system, the thalamus is shown to be involved in many limbic functions of the human brain. The major direct connection of the thalami with the hypothalamic nuclei is known to be through the mammillothalamic tract...

OBJECTIVE: Computational human body models (HBMs) are nominally omnidirectional surrogates given their structural basis in human anatomy. As a result, such models are well suited for studies related to occupant safety in anticipated highly automated vehicles (HAVs). We utilize a well-validated HBM to study the head and neck kinematics in simulations of nontraditional occupant seating configurations. METHODS: The GHBMC M50-O v. 4.4 HBM was gravity settled into a generic seat buck and situated in a seated posture...

BACKGROUND: Laron syndrome is an autosomal disease resulting from mutations in the growth hormone receptor (GHR) gene. The only therapeutic treatment for Laron syndrome is recombinant insulin-like growth factor I (IGF-I), which has been shown to have various side effects. The improved Laron syndrome models are important for better understanding the pathogenesis of the disease and developing corresponding therapeutics. Pigs have become attractive biomedical models for human condition due to similarities in anatomy, physiology, and metabolism relative to humans, which could serve as an appropriate model for Laron syndrome...

A PC Program for x ray Monte Carlo (PCXMC) has been used to calculate organ doses in patient dosimetry and for the exposure assessment in epidemiological studies of radiogenic health related risks. This study compared the dosimetry from using the built-in stylized phantoms in the PCXMC to that of a newer hybrid phantom library with improved anatomical realism. We simulated chest and abdominal x ray projections for 146 unique body size computational phantoms, 77 males and 69 females, with different combinations of height (125-180 cm) and weight (20-140 kg) using the built-in stylized phantoms in the PCXMC version 2...

The purpose of this study was to suggest modifications of autopsy techniques in order to improve post-mortem diagnosis of arterial gas embolism (AGE) based on multidisciplinary investigation of SCUBA diving fatalities. Five adult human cadavers from the voluntary donation program of the Human Anatomy Laboratory, and eight judicial autopsied bodies of SCUBA divers from the Forensic Pathology Service were assessed. Before performing any autopsies, we accessed the diving plan and the divers' profiles for each case...

BACKGROUND: With the resurgence of tick-borne diseases such as Lyme disease and the emergence of new tick-borne pathogens such as Powassan virus, understanding what distinguishes vectors from non-vectors, and predicting undiscovered tick vectors is a crucial step towards mitigating disease risk in humans. We aimed to identify intrinsic traits that predict which Ixodes tick species are confirmed or strongly suspected to be vectors of zoonotic pathogens. METHODS: We focused on the well-studied tick genus Ixodes from which many species are known to transmit zoonotic diseases to humans...

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has become an important and validated objective measure in surgical decision making and post-operative assessment. Isolated grade I or II PCL injuries can usually be treated non-operatively...
