Temporal expression and specific localization of tenomodulin with reference to vascular endothelial growth factor A and calcitonin gene-related peptide in developing diaphragm in mice.

Tenomodulin (TNMD) is related to chondromodulin-1, a cartilage-derived growth regulator. It is specifically expressed in hypovascular connective tissues, including tendons and ligaments. Vascular endothelial growth factor A (VEGF-A) and calcitonin gene-related peptide (CGRP) correlate with angiogenesis and neurogenesis, respectively, during development.

Anatomical study of brachial plexuses of a koala, a Tasmanian devil, and a common ringtail possum.

Background: Marsupials have a narrower range of forelimb morphological features than placental mammals. It is hypothesized that this is due to a constraint in the reproductive biology of marsupials. The constraint is that newborn marsupials must crawl into their mother's pouch.

Vascular anatomy of the lateral meniscus with special focus on the joint capsule.

Previous studies have reported that the lateral meniscus (LM) has two regions, the popliteal hiatus area (PH) with a scarce blood supply and the roots with an abundant one. However, the description of its vascular anatomy remains insufficient. We hypothesized that the difference in the width of the meniscus hilum (MH) affects the scarcity and abundance of blood supply to the LM.

Effects of female bone marrow transplantation on male reproductive organs.

Graft-versus-host disease (GVHD), an adverse effect after bone marrow transplantation (BMT), may affect male reproductive function. It is hypothesized that a sex-mismatched BMT induces GVHD in male reproductive organs because female immune cells are not immunologically tolerant to specific antigens of the male organs. However, this hypothesis has not been experimentally verified using male (M) recipient animals following BMT from the female (F) donors.

Serum ANGPTL4 and SIRT1 factor levels and the Carotid Atherosclerotic plaque stability relationship analysis.

This study was to investigate the relationship between the levels of Angiopoietin-Like Protein 4 (ANGPTL4) and Silent Mating-type Information Regulation 2 Homolog 1 (SIRT1) and the stability of carotid atherosclerotic plaque. For this purpose, 108 patients with coronary heart disease in our hospital from Jan 2021 to May 2022 were selected as the coronary heart disease (CHD) group and 80 patients with the healthy examination as the control group. Patients' serum levels of ANGPTL4 and SIRT1 were collected, and their stability of carotid atherosclerotic plaque was determined by carotid ultrasound.

Pathophysiological consequences and treatment strategy of obstructive jaundice.

Obstructive jaundice (OJ) is a common problem in daily clinical practice. However, completely understanding the pathophysiological changes in OJ remains a challenge for planning current and future management. The effects of OJ are widespread, affecting the biliary tree, hepatic cells, liver function, and causing systemic complications.

Structural and CBCT analysis of mandibular canal microvessels expressing neurotransmitters in human cadavers.

Purpose: This study focused on the detailed structure of microvessels of the neurotransmitter-positive vasa nervorum of the inferior alveolar nerve, vein, and artery in the mandibular canal (MC) to obtain information for improved safety in dental treatments. We also observed the detailed structure of the MC from the mental foramen to the mandibular foramen using cone-beam computed tomography (CBCT).

Methods: In this study, mandibles from 45 sides of 23 human cadavers aged 76-104 years were examined by microscopy, immunohistochemistry, and CBCT analysis.

Expression of neurotransmitters, vasculogenesis markers and myosin heavy chain isoforms in the masseter muscle of senescence-accelerated mouse prone 8 mice.

Background: Learning and memory deficits and pathologic changes in the hippocampus caused by toothlessness and soft diet feeding are related to reduced masseter muscle (MM) function.

Objective: Myosin heavy chain (MyHC) isoform expression in the MM also changes under different chewing conditions. The neurotransmitter calcitonin gene-related peptide (CGRP) and vascular endothelial growth factor A (VEGF-A) are involved in MM formation.

[Purpose] This study aimed to determine the relationship between thoracic lateral deviation, the bilateral ratio of the thoracic shape, and the bilateral ratio of the thoracic and lumbar iliocostalis muscles during resting sitting and thoracic lateral translation. [Participants and Methods] We included 23 healthy adult males in the study. The measurement tasks were resting sitting and thoracic lateral translation relative to the pelvis.

The interrelationship between three-dimensional foot mobility and bodyweight bearing.

[Purpose] To clarify the three-dimensional nature of foot mobility and its interrelationships within the foot due to bodyweight bearing. [Participants and Methods] Data regarding left foot mobility due to body weight bearing were collected from 31 healthy adults. Foot shape differences while sitting and standing, and their interrelationship were examined.

Relationship between the thoracic asymmetry in standing position and the asymmetry of ankle moment in the frontal plane during gait.

[Purpose] We aimed to investigate the relationship of thoracic asymmetry in standing position with asymmetry of the internal ankle moment in the frontal plane during gait. [Participants and Methods] The following measurements were recorded in 22 healthy adult males using a 3D motion analyzer and force plates: thoracic lateral deviation, asymmetrical ratios of the upper and lower thoracic shape, internal ankle moment in the frontal plane, mediolateral deviations of the center of mass and center of pressure. [Results] In the standing position, the thorax was deviated to the left relative to the pelvis, and the upper and lower thoracic shapes were asymmetrical.

Neonatal corticosterone administration increases p27-positive Sertoli cell number and decreases Sertoli cell number in the testes of mice at prepuberty.

Cortisol and corticosterone (CORT) are steroid, antistress hormones and one of the glucocorticoids in humans and animals, respectively. This study evaluated the effects of CORT administration on the male reproductive system in early life stages. CORT was subcutaneously injected at 0.

The mechanism of Yinchenhao decoction in treating obstructive-jaundice-induced liver injury based on Nrf2 signaling pathway.

Background: Obstructive jaundice (OJ) is caused by bile excretion disorder after partial or complete bile duct obstruction. It may cause liver injury through various mechanisms. Traditional Chinese medicine (TCM) has a lot of advantages in treating OJ.

GIT1 is an untolerized autoantigen involved in immunologic disturbance of spermatogenesis.

Male haploid cells, spermatids and spermatozoa, that appear after the establishment of immune tolerance express novel cell surface and intracellular proteins that can be recognized as foreign antigens by the self-immune system. However, these germ cells do not normally evoke a pathological immune response. The immune-privileged micro-circumstance in testis involving the blood-testis-barrier formed by Sertoli cells protects these germ cells from autoimmune attack.

Characteristic expression of CGRP and osteogenic and vasculogenic markers in the proximal and distal regions of the rib during male mouse development.

Background: Neuropeptide calcitonin gene-related peptide (CGRP) is a neurotransmitter related to vasculogenesis and osteogenesis during bone formation and organ development. From the foetal period to the postnatal period, the thorax, which is necessary for lung respiration, forms. The thorax exhibits the same cartilage ossification as the bones of the extremities, but a specific system within the thorax exists as costal cartilage after birth.

Heat shock protein A4L is a potent autoantigen for testicular autoimmunity in mice.

Experimental autoimmune orchitis (EAO) may be used as a model to investigate immunological infertility in men. Murine EAO is induced via immunization with auto-immunogenic antigens (AIAgs) from testicular germ cells (TGCs). CD4 + T cells play a crucial role in EAO induction.

Neonatal maternal separation increases the number of p27-positive Sertoli cells in prepuberty.

Neonatal maternal separation (NMS) is an experimental model for early life stress, which affects the growth and development of various organs, resulting in adverse health effects in humans and animals. In our previous study, we demonstrated that NMS [(0.5-, 1-, 2-h/day NMS, from postnatal day (PND) 1-10] induced morphological changes to the male reproductive system, including decreased Sertoli cell numbers in mouse testes at PND 70.

Cytonuclear Estrogen Receptor Alpha Regulates Proliferation and Migration of Endometrial Carcinoma Cells.

Objective: The effects of estrogen on cells are mediated by the estrogen receptor α (ERα) which localizes at the peri-membrane, cytoplasm, and the nucleus of cells. Therefore, we intended to investigate how cytonuclear ERα plays its roles in different cellular activities.

Methods: We used amino acid substituted ERα that localized at the cytoplasm and nucleus but has no direct DNA-binding activities.

Comparison of CGRP distributions in the maxillary sinus and trigeminal ganglion between elderly dentulous and edentulous humans.

Thickening of the Schneiderian membrane (SM, mucosa of the maxillary sinus) appears in the paranasal sinus. Information on SM thickening is available for patients receiving sinus lift treatments, which is a risk factor for SM excretory dysfunction. However, more information is needed on the structure of the SM and the relationship between the maxilla sinus and palatine with the alveolar bone and the SM for dental implant treatment in the human maxilla.

The topography and morphometrics of the pubic ligaments.

Background: Conflicting anatomical reports and the little attention given to the pubic ligaments impede the interpretation of radiological and clinical examinations on groin pain. Morphometric data on the pubic ligaments are lacking.

Methods: The muscular relations of the symphysis pubis were examined in layered dissection (n = 10), hemipelves (n = 60) and (un)stained plastinated body slices of body donors (n = 3).

Analysis of the mylohyoid nerve in elderly Japanese cadavers for dental implant surgery.

Objectives: Injury to the mandibular nerve (MN) branches may cause pain and irregular occlusal movement during mastication after mandibular dental treatments. Growing evidence indicates that the calcitonin gene-related peptide (CGRP) plays a key role in the development of peripheral sensitization and the associated enhanced pain, suggesting it may be a sign to ensure a safe and reliable dental implant treatment. Our focus was on the distribution of the MN branches and their communication with the lingual nerve (LN), the localized expression of CGRP, and the identification of a pain area related to the mylohyoid muscle (MM) fascia in the mandibular floor.

The arterial blood supply of the symphysis pubis - Spatial orientated and highly variable.

Background: Open surgical treatment of the pubic region and adductor related pathologies require an exact knowledge of the arterial blood supply of the symphysis pubis that seems furthermore important to explain the hematogenous occurrence of symphysitis. Pubic bone marrow oedema (PBME) is a frequent occurring magnetic resonance imaging finding in groin pain. However, even asymptomatic athletes present PBME and a correlation to the physical activity or higher blood flow was suggested.

Neonatal maternal separation causes decreased numbers of sertoli cell, spermatogenic cells, and sperm in mice.

Neonatal maternal separation is an experimental model used to evaluate the effects of toxic stress in neonates, or early life stress. Although various physiological and psychological stresses during childhood have been reported, the effects of neonatal maternal separation on the male reproductive system remain unclear. Therefore, the present study evaluated the effects of neonatal maternal separation on the male reproductive system.

miR-499a promotes PANC-1 cell proliferation by down-regulating PDCD4 expression in pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive digestive system tumors, but study of the molecular mechanism of occurrence and development of PDAC is considerably limited. In order to better understand the potential pathogenesis, the differentially expressed miRNAs were screened in PDAC and adjacent tissues using miRNAs microarrays. We found that miR-499a was significantly up-regulated in PDAC tissues compared with adjacent tissues, and protein-protein interaction (PPI) and gene ontology (GO) analyses indicated programmed cell death protein 4 (PDCD4) is a key target gene of miR-499a, which is involved in the regulation of transcription, cellular biosynthetic process, RNA metabolic process, and other multiple biologic processes.
