Título: The Aleph and the écorché
Fuente: Eur. j. anat;23(4):313-314, jul. 2019. ilus.
Idioma: en.
Resumen: The woodcuts in Vesalius' De humani corporis fabrica reflect both philosophical and theological ideas. A previously unrecognized Hebrew symbol in De humani is the écorché in the second muscle tableau. Its pose is evocative of an Aleph, the first letter of the Hebrew alphabet. The Aleph is a symbol of the brain and represents the highest level of knowledge and wisdom beneath that of god himself. With arms pointing to heaven and earth, the second écorché appears to anthropomorphize this ancient Hebrew symbol and may be a Humanist re-imagination of Old Testament imagery to demonstrate the famous Latin aphorism, nosce te ipsum, and the importance of anatomic dissection for the understanding of the human condition

Título: The lumbo-sacral transitional vertebra (LSTV) sacrum with negligible sacral kyphosis: a case report with an evolutionary review
Fuente: Eur. j. anat;23(4):307-312, jul. 2019. ilus, tab.
Idioma: en.
Resumen: Monkey and other hominids species have 5 sacral segments in 10% cases. The similar frequencies for each 6-segmented and 4-segmented sacra in human are known as lumbo-sacral transitional vertebra (LSTV). Achieving the erect posture in human has necessitated much skeletal modification, but these are more apparent in the lumbosacral region. Sacral kyphosis is a distinguishing feature of the human sacrum, which helps to differentiate them from the animal. The monkey has a sacral index near 80, and humans a sacral index is near 100. The sacral index was 88 in six-segmented sacra with negligible sacral kyphosis, having sacralisation of the 5th lumbar vertebra. Therefore, SI is 88 and lack of sacral kyphosis challenge its human origin. On the contrary, gross morphology, actual sacral index, and comparison with apes gave sufficient evidence of human origin. Later excluding 5th Lumbar vertebra, the sacral index is 107.34 and might belong to a male which corresponds with bone bank record

Título: The debatable Arcade of Struthers: is it still time to consider it?
Fuente: Eur. j. anat;23(4):301-305, jul. 2019. ilus.
Idioma: en.
Resumen: The Arcade of Struthers is reported to be a structure that may play a role in ulnar nerve compression in the arm. The aim of this research is to better understand the relationship between the ulnar nerve and this anatomical structure of the medial aspect of the arm, and to investigate its morphology. In 54 fresh arms (26 female, 28 male, 24 left and 30 right limbs), with a median age of 67 years (range 45-83 years), the ulnar nerve and all the surrounding structures were dissected from the brachial plexus to the ulnar groove of the medial epicondyle. We identified muscular fibers from the medial head of the triceps over the ulnar nerve in 12 examined limbs (24%). In all specimens the ulnar nerve was not compressed by any band and no sign of hourglass constriction was found. The extension of the muscular fibers was 34mm (min 20 mm, max 51 mm) and their average distance from the medial epicondyle was 61 mm (min 25 mm, max 80 mm). The findings of this study are not supportive for the presence of an arcade as previously described. Although this structure was reported to be a rare site of ulnar nerve compression at the elbow, it was not described by Struthers. The terminology "Arcade of Struthers" seems to be misleading due to the similarity with the other eponym "Ligament of Struthers"

Título: Efficacy of six artemisinin-based combination therapies in the attenuation of Plasmodium berghei-induced testicular toxicity in Swiss mice
Fuente: Eur. j. anat;23(4):289-300, jul. 2019. ilus, graf, tab.
Idioma: en.
Resumen: Many artemisinin-based combination therapies (ACTs) have been approved for malaria treatment, yet reports indicate that some ACTs pose reversible testicular toxicity; however there is no comparative study of these ACTs on the testes in a curative malarial model. We investigated the ameliorative activity of six ACTs on Plasmodium berghei (PB) induced perturbations in testicular antioxidants, serum testosterone levels, sperm motility and the testes microanatomy. Forty male Swiss mice were divided into 8 groups of 5 each: Group 1 normal control (NC), uninfected and untreated, received placebo; group 2 was parasitized non-treated (PNT), while groups 3 - 8 received PB inoculum intraperitoneally. Initial parasitemia was established after 72 hours. Groups 3 - 8 thereafter received oral therapeutic doses of artesunate/amodiaquine (PBAA), artesunate/mefloquine (PBAM), artesunate/sulfadoxine-pyrimethamine (PBASP), artemisinin-piperaquine (PBAP), dihydroartemisinin/piperaquine (PBDP) and artemether/lumefantrine (PBAL) per kg body weight respectively. final parasitemia was performed 24 hours after last treatment, and animals euthanized. Result for parasitemia level was significantly (p < 0.05) declined in ACT-treated groups, except PBASP compared with PNT. Enzymatic antioxidants were significantly (p < 0.0001) altered in ACT-treated groups compared to PNT. Non-enzymatic antioxidants were significantly (p < 0.0001) increased in PBDP compared to NC and PNT. Progressive sperm motility significantly (p < 0.0001) declined in PNT, PBASP, PBAP and PBDP groups compared to NC. Testosterone showed decreasing trend in PBAP compared to PNT, and severe testicular distortions were demonstrated in PNT, PBASP, PBAP and PBDP. This study concludes that therapeutic doses of AA, AM and AL moderately protects against the deleterious effects of Plasmodium berghei-induced testicular toxicity in Swiss mice

Título: Variations in origin and branching pattern of hepatic arteries and their clinical significance
Fuente: Eur. j. anat;23(4):279-287, jul. 2019. ilus, tab.
Idioma: en.
Resumen: Hepatobiliary surgeries require extensive knowledge of variations in the origin and branching pattern of arteries extending from the coeliac trunk till the cystic artery. This study was aimed at documenting all possible variations observed in the hepatic arterial tree by meticulous dissection of livers in formalin-fixed cadavers. Twenty formalin-fixed cadavers were meticulously dissected to study the hepatic arterial variations.The common hepatic artery originated from the coeliac trunk, common hepatogastric trunk and common hepatosplenic trunk in 85%, 5%, and 5% respectively. It was absent in 5%. It gave rise to the gastroduodenal and proper hepatic arteries in 85%, trifurcated into gastroduodenal, left and right hepatic arteries in 5%, and left hepatic, right hepatic and cystic arteries in 5%. The proper hepatic artery continued from the common hepatic artery in 85%, and was absent in 15%. It bifurcated into left and right hepatic arteries in 45%, showed a trifurcating pattern in 20% cases, gave rise to 3 separate hepatic branches in 5%, and continued as left hepatic artery alone in 15%. The left hepatic artery originated either from the proper hepatic artery or was a direct continuation of it in 85%, from the common hepatic artery in 10%, and the superior mesenteric artery in 5% cases. It gave rise to the cystic artery in 5%. The right hepatic artery originated from proper hepatic artery in 70%, abdominal aorta in 5%, coeliac trunk in 10%, superior mesenteric artery in 5%, common hepatic artery trifurcation in 10%, and gave rise to the cystic artery in 80%. The cystic artery was absent in 5%. Some of the findings have been reported in other studies, while some were newly reported in the present study. Knowledge of hepatic arterial variations is necessary to prevent complications involving several specialties including interventional radiology, endovascular surgery, chemotherapeutic procedures, hepatobiliary surgery as well as living donor liver transplantation surgeries

Título: Prevalence and distribution of dilacerations in the permanent dentition of an Iranian population
Fuente: Eur. j. anat;23(4):273-277, jul. 2019. graf, tab.
Idioma: en.
Resumen: A thorough knowledge of external dental root morphology is fundamental for having successful endodontic, orthodontic and surgical treatments in dentistry. The aim of this anatomical study was to determine the incidence of tooth dilacerations in Kerman, a province in the Southeastern Islamic Republic of Iran. A cross-sectional study was performed on a total of 3150 teeth from 800 PA radiographs; 100 radiographs from each 8 anatomic divisions of the dental arch, within a Kerman population. The numbers of radiographs were equal between 2 genders; 400 from females and 400 from males. Radiographs were studied by 3 specialists in this field in order to determine and record the prevalence and distribution of dilacerations in different teeth of this population. Amongst the total of 3150 teeth from 800 radiographs, 52 teeth (1.65%) showed dilacerations. The prevalence of this anomaly was 7.5% in males and 5% in females, and the distribution was almost equal between different teeth of the maxilla (2%-4%); meanwhile in the mandible, the maximum prevalence was in third molars (14%) and the rate was nil in anterior teeth (Spss and Excel softwares, IBM). The prevalence of tooth dilacerations was almost equal between genders in the Kerman population that was studied. The findings indicated that the presence of dilacerated roots was more prevalent in females in the mandibular arch, while this anomaly was more prevalent in males in the maxillary arch. Interestingly, none of the mandibular incisor teeth displayed this anomaly

Título: Is lead in Nagabhasma toxic to liver? - A histological evaluation
Fuente: Eur. j. anat;23(4):267-272, jul. 2019. ilus.
Idioma: en.
Resumen: Ayurvedic medicines is known to use heavy metals in their preparation. Nagabhasma is one such form of a lead-based medicine. Even though lead is known to be toxic to several systems of the human body, according to Ayurveda, the metallic toxicity of the lead gets nullified and thereby imbibes medicinal property when it is prepared using many herbs and stringent traditional methods. Therefore, the present study is designed to evaluate the effect of such detoxified lead in various stages of authentically prepared Nagabhasma on the histopathology of liver in comparison with lead acetate and commercially available Nagabhasma-administered animals. Less than the human-equivalent doses of Nagabhasma at four intermittent stages of its preparation were administered orally for 30 days and 60 days (short term and long term exposure) to Wistar rats. In another set of experiment, test-material-administered animals were kept under observation for an additional period of two months to record the residual effect. Immediately after the administration and after the observation period, the animals were sacrificed to collect the liver for histopathological examination. The histopathological results of the immediate and residual effects showed varying alterations in the microarchitecture of the liver as the stages of Nagabhasma preparation advanced. The final product (stage 4 bhasma), showed very less toxic effect in comparison with other stages. In conclusion, the results state that, by following the traditional procedures while preparing Nagabhasma, the metallic lead gets converted into non-toxic organometallic compound

Título: Accessory mandibular foramina and bifid mandibular canals - an anatomical study
Fuente: Eur. j. anat;23(4):261-266, jul. 2019. ilus, tab.
Idioma: en.
Resumen: Bifid mandibular canals associated with accessory mandibular foramina are claimed to pose complications in oral surgery and allied procedures resulting in paraesthesia and haemorrhage, due to injury to the divisions of inferior alveolar nerves and vessels passing through them. Sometimes these nerves escape the effect of anaesthetics leading to difficult inferior alveolar nerve block. These variant canals serve as a source of spread of cancer from cortical to cancellous part of the mandible. The current descriptive study included thirty intact, dry, adult human mandibles. They were examined macroscopically to note the presence of accessory mandibular foramina and the accessory mandibular canals arising from them. These aberrant canals were probed and their length was noted. The probed mandibles were X-rayed to observe the course of these canals. The location of the foramina was determined from nearby anatomical landmarks.Six mandibles (20%) showed accessory mandibular foramina. The length of the accessory mandibular canals originating from the accessory mandibular foramina was found to vary from 0.9 cm to 4.5 cm. On X-ray films, the variant canals were noted to proceed towards third molar or towards the angle of mandible. Some of these canals merged with the main mandibular canal. The findings of the study will be helpful in oral surgery, radiology and cancer therapy

Título: The 3-D muscular structure of the human pancreaticobiliary junction
Fuente: Eur. j. anat;23(4):253-259, jul. 2019. ilus.
Idioma: en.
Resumen: The musculature of the human pancreaticobiliary junction (PBJ) is implicated in several pathologies and is of significance to clinicians who perform endoscopic retrograde cholangiopancreatography (ERCP). This study sought to describe the musculature of the human PBJ by generating a three-dimensional reconstruction of histologic sections. A single pancreaticoduodenal specimen was removed en bloc from an embalmed cadaver with no pancreaticoduodenal disease. Sections were stained with Masson's trichrome and the staining pattern of muscle fibers was used to generate information regarding their location and orientation. The outline of groups of muscle fibers taken from photomicrographs of alternate thin serial sections were highlighted based upon their orientation (circular or longitudinal) and location (duodenal or papillary). Data point co-ordinates were used to create a 3-D image reconstruction.A total of 91 composite serial cross-sections were reconstructed. Circular and longitudinal muscle fibers formed a completely investing muscle layer around both the bile and pancreatic ducts, and there was a clear distinction between the intrinsic muscles of the PBJ and those of the duodenal wall. Circular fibers were particularly dense distal to the confluence of the ducts. Longitudinal fibers were incompletely distributed around the pancreaticobiliary sphincter and did not extend to the tip of the major duodenal papilla. This model supports the well-established concept of an intrinsic pancreaticobiliary sphincter composed of circular and longitudinal muscle fibers, distinct from the surrounding duodenal muscle. Targeting the distal end of the PBJ during ERCP would only partially disrupt this muscular sphincter mechanism

Título: Atomoxetine enhances memory and proliferation in adult male rat hippocampus
Fuente: Eur. j. anat;23(4):243-251, jul. 2019. ilus, graf.
Idioma: en.
Resumen: Atomoxetine (ATX) is a noradrenaline reuptake inhibitor used to treat Attention deficit hyperactive syndrome (ADHD), or improve cognition in normal subjects. The cognitive effects of ATX require inputs from the hippocampus. Moreover, proliferation is said to be located in the dentate gyrus (DG) of the hippocampus.In the present study, we hypothesised that ATX improves memory and proliferation of the adult rat hippocampus. To test this hypothesis, 5 intraperitoneal injections of ATX (30 mg/kg/day) over 5 consecutive days were delivered to rats. 30 minutes after the last injection, spatial memory was tested using the Novel location recognition (NLR) test. Proliferation of hippocampal cells was quantified using immunohistochemistry for the proliferative marker Ki67. ATX-treated rats showed cognitive enhancement in the NLR task and increase in cell proliferation in the Subgranular zone (SGZ) of the DG, compared to saline-treated controls. The results demonstrate that ATX is able to enhance cognition through increasing the levels of proliferation in the adult rat brains
