A major component of tooth innervation is made of capsaicin-sensitive primary afferents (CSPA). These fibers play a key role in tooth pain and inflammation; little is known, however, about the role of CSPA in tooth eruption. The aim of this study was to examine the role of the capsaicin-sensitive afferents in the process of eruption of intact rat incisors. CSPA fibers in several rat groups, were subjected to one of the following experimental procedures: systemic chemical ablation, systemic ablation followed by chemical sympathectomy and localized activation...

Chronic testicular pain remains an important challenge for urologists. Investigation of the innervation of male gonads thus becomes essential for deepening our understanding of their regulatory roles in male reproductive physiology and pathophysiology. Studies of testicular innervation are mainly limited to the intratesticular peptidergic nerves of the testis by immunohistochemical and acetylcholinesterase histochemical investigations in some animals. Little is known about the detailed, overall distribution in general experimental animal testis...

Parkinson's disease is caused by damage to substantia nigra dopaminergic neurons. Factors such as oxidative stress, inflammatory factors, and acetylcholinesterase activity may induce this disease. On the other hand, crocin-one of the active ingredients of saffron-has anti-oxidant and anti-inflammatory properties. This study was performed to evaluate the protective effect of crocin to decrease dopaminergic neuron damage and Parkinson's disease complications induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)...

The increase in autoimmune diseases in recent years has drawn attention back to the thymus, with new approaches to improve and/or restore immune function being investigated. As the primary lymphoid organ responsible for functional T cell development, studies on the pre-/post-natal development of this organ and T lymphocytes in human and other species are of special interest. During our screening studies we observed structures that had not been described or mentioned previously, and named them "epitheliostromal sheaths"...

We developed a technique to analyze the high-resolution three-dimensional (3D) structure of seminiferous tubules. It consists of segmentation of tubules in serial paraffin sections of the testis by marking the basement membrane with periodic acid-Schiff or a fluorescent anti-laminin antibody followed by 3D reconstruction of tubules with high-performance software. Using this method, we analyzed testes from mice at different ages and accurately elucidated the 3D structure of seminiferous tubules, including the number and length of tubules as well as the numbers of connections with the rete testis, branching points, and blind ends...

Osteons are the primary sites of cortical bone lesions. However, many aspects of osteon microstructure remain poorly understood. This study aimed to explores interindividual differences in the osteon morphotype distributions in the human femoral diaphysis by evaluating the secondary osteon distributions in samples from human femurs. Two anonymized bone fragments from two modern Japanese femurs were examined. Twelve continuous transverse femoral diaphysis specimens were prepared from each fragment. Imaging examinations were conducted using a circularly polarized light microscope, and cross-sectional images were rendered using graphical synthesis software...

Using an immunocytochemical technique, we have studied the distribution of fibers and cell bodies containing somatostatin-28 (1-12) [SOM-28 (1-12)], calcitonin gene-related peptide (CGRP), and substance P (SP) in the brainstem of Saimiri sciureus. The distribution of the peptidergic cell bodies was very restricted: perikarya containing SOM-28 (1-12) were only observed in the substantia grisea centralis, while no immunoreactive cell bodies containing CGRP or SP were visualized. Fibers containing SOM-28 (1-12), CGRP, or SP were widely distributed in the brainstem: immunoreactive fibers containing SOM-28 (1-12) showed the most widespread distribution and were the most abundant...

The rotator cable is a semicircular thickening of the glenohumeral joint capsule. It travels between tubercles of the humerus and interweaves with the supra- and infraspinatus muscle tendons. The rotator cable anchors these tendons to the tubercles, playing the role of a suspension bridge. However, little is known about the modifications of this cable that result from pathologies to the rotator cuff tendons. Thus, we aim to compare the morphology of the normal rotator cable with cables in specimens with rotator cuff injuries...

The pampas deer (Ozotoceros bezoarticus) is a medium-sized deer that weighs 20-40 kg. Historically, it was a widely distributed species that occupied a wide range of open habitats, including pastures, pampas, and Brazilian savanna. However, it is currently considered to be a species at risk of extinction. Anatomical descriptions of the arterial supply are very useful when working with exotic mammals. Knowledge of the locations, the distribution pattern, and the anatomical relationships of the arteries is required when performing any intervention...

Coronary vessel development has been investigated in avian and mouse embryonic hearts. Quail embryos are a useful tool to examine vascular development, particularly because the QH1 antibody and transgenic quail line, Tg (tie1:H2B-eYFP), are useful to trace endothelial cells. However, there are only a few descriptions of the quail coronary vessels. Using ink injection coronary angiography, we examined the course of coronary vessels in the fetal quail heart. The major coronary arteries were the right and left septal arteries, which, respectively, branched off from the right and left coronary stems...

The pancake kidney (PK) is a rare type of renal anomaly in which both kidneys completely fuse without an isthmus. In the previous reports, PKs have double ureters and are located in the pelvic cavity. We encountered a rare case of PK with a single ureter, which is located in the left retroperitoneal space, in a 95-year-old female cadaver, which was detected during a dissection course. In our case, the major calyces joined to form a single renal pelvis, which continued as a single ureter. To the best of our knowledge, this is the first report on PK with a single ureter that is located not in the pelvic cavity but in the retroperitoneal space...

To evaluate the anatomical classification and location of breast sentinel lymph nodes, preoperative computed tomography-lymphography examinations were retrospectively reviewed for sentinel lymph nodes in 464 cases clinically diagnosed with node-negative breast cancer between July 2007 and June 2016. Anatomical classification was performed based on the numbers of lymphatic routes and sentinel lymph nodes, the flow direction of lymphatic routes, and the location of sentinel lymph nodes. Of the 464 cases reviewed, anatomical classification could be performed in 434 (93...

The lateral ligament complex of the ankle is involved in a large proportion of ankle sprains. The calcaneofibular ligament (CFL) is often involved in severe injuries. The purpose of this study was to evaluate the anatomical variation and laterality of the CFL to improve our understanding of the mechanisms of CFL-related injuries. This study utilized 110 paired ankles from 55 formalin-fixed Japanese cadavers (33 male and 22 female). The length and width of the CFL and the angle created by the CFL and long axis of the fibula (CF angle) were measured after exposing the CFL by careful dissection from the surrounding tissues...

Clavicle fracture is known to be one of the injuries frequently occurring in the elderly. The purpose of this study was to characterise the internal structures that might correlate with the higher incidence of lateral clavicle fracture in the elderly. Twenty clavicles were collected from ten Japanese cadavers ranging from 70 to 99 years (83.6 ± 7.6), scanned, and three-dimensional computed tomography (3D CT) images reconstructed. The clavicle lengths were divided into five equal segments. The four demarcation lines from the acromial end of the clavicle were defined as the observation points A, B, C, and D...

During an organism's evolution, functional adaptations help species to become better suited to their ecological niches. From the morphological aspect, these adaptations are reflected in the anatomical specializations of different organs. Specializations of the lingual organ is a critical adaptation of birds, such as the white-headed duck (Oxyura leucocephala), that enables their nutritional requirements to be met. For optimal use of the available food resources, the white-headed duck utilizes three methods of food collection, namely pecking, grazing and filter-feeding...
