Who, When, and Where Wrote the Book of Genesis?

  Who, When, and Where Wrote the Book of Genesis?  A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN     CONTENT [i]   Abstract [ii]   Introduction [iii]   Egyptian physician [iv]   Asian diviner [v]   Conclusion [vi]   References [vii]   Application [i]   Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research.

[ii]   Introduction One of the first studies devoted to the diagnosis of LCF injury demonstrated a variety of symptoms: groin pain, hip stiffness, sometimes long-standing minimal clinical findings, or signs similar to osteoarthritis (1997GrayA_VillarRN). More than a decade later, researchers concluded: "Unfortunately, there is no specific test for detecting LCF tears." The signs known at that time were nonspecific and were also observed in other intra-articular pathologies of the hip joint (2010CerezalL_Pérez-CarroL). The a...

[ii]   Annotation Background:  Intraarticular hip pain represents a substantial clinical challenge, with recent studies implicating lesions in the ligamentum teres as potential contributors. Even more so, damage to the ligamentum teres is particularly prevalent among young patients undergoing joint-preserving interventions. Although several studies have investigated the biomechanical attributes of the ligamentum teres,...

1884SuttonJB

  Fragments from the article Sutton JB. Ligaments: Their Nature and Morphology (1884). The author discovered that in the ostrich the ligamentum capitis femoris (LCF) was not continuous with the ambiens muscle, but with a muscular slip which ran parallel with the-muscle, and ended in the adductor mass. This publication develops the theme of article 1883SuttonJB .   Quote pp. 228-229 I must now pass on to consider certain ligaments of the appendicular skeleton, commencing with some additional remarks on the ligamentum teres. The Journal of Anatomy and Physiology, vol. xvii January 1883, contains a short article on the ligamentum teres, in which I have endeavoured to point out that many ligaments are the tender of muscles which were originally in relation with the joint; but the parent muscle has either formed new attachments or become obsolete, whilst the tendon remains as a passive element in the articulation. In addition to the ligamentum teres the following structures ...

  Abstract of the article Chen HH, Li AF, Li KC, Wu JJ, Chen TS, Lee MC. Adaptations of ligamentum teres in ischemic necrosis of human femoral head (1996). The authors investigate the strength of the ligamentum capitis femoris (LCF)  in avascular necrosis and femoral neck fracture.  The text in Russian is available at the following link: 1996ChenHH_LeeMC . Annotation   Little is known about the biomechanical properties of human ligamentum teres. To more fully understand the ligamentum teres, its dimensions and mechanical properties were measured in 22 cases of acute fracture of the femoral neck and 21 cases of ischemic necrosis of the femoral head. The specimens first were preconditioned and then loaded to failure with a testing machine at a fast strain rate of 100% s(-1). The ischemic necrosis group had a significantly larger volume (3.09 +/- 1.81 ml versus 1.30 +/- 0.62 ml) and cross section area (65.3 +/- 59.1 mm2 versus 30.6 +/- 27.2 mm2) than did the acute f...

  Ancient Textual Sources on Ligamentum Teres: Context and Transmission S.V. Arkhipov, I.V. Prolygina   KEYWORDS: ancient medicine; ancient traumatology; Galen; Hippocrates; hip joint; ligamentum capitis femoris; ligament of head of femur; ligamentum teres. SUMMARY Background. One of the least researched anatomical structures of the human body is the ligament of head of femur, most often referred to as ligamentum teres. The history of the nomination of this term, medical contexts of its use, the etymology and the first synonyms (Figure 1) are not sufficiently understood. Purpose. The purpose of the article is to present the most complete collection of evidence from ancient medical authors about the term ligamentum teres, trace the history of its nomination and analyze the gradual changes in the level of knowledge about the anatomy, mechanical and geometric properties of this structure, its pathology and treatment methods. Methods. The study is based on an inter...
