Changes in bite force, masticatory muscle thickness, and facial morphology between primary and mixed dentition in preschool children with normal occlusion.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The study of stomatognathic system development can provide useful data for recognition of deviations from normality. Thus, a longitudinal examination of 14 children with normal occlusion from primary (stage I, mean age 59.21+/-8.40 months) to early mixed dentition (stage II, 77.57+/-5.92) was performed. Bite force was measured with a pressurized tube and correlated with ultrasonographic masseter and anterior portion of temporalis muscle thicknesses (at rest and maximal intercuspation), facial dimensions, age, and body mass index (BMI). Facial dimensions were assessed by standardized frontal photographs as follows: ante...

The precision of four commonly used surgical landmarks for locating the facial nerve in anterograde parotidectomy in humans.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In addition to using intra-operative facial nerve monitoring in helping to locate the position of the facial nerve in anterograde parotidectomy, numerous soft tissue and bony landmarks have been proposed to assist the surgeon in the early identification of this nerve. There is still dispute within the literature as to the most effective method, if any, of locating the nerve. The purpose of this study was to measure the distance (in twenty-six embalmed cadavers) from four of the most commonly used surgical landmarks to the main trunk of the facial nerve-the posterior belly of digastric muscle (PBDM), the tragal pointer ...

Some variations in lymphatic drainage of selected bronchopulmonary segments in human lungs.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Interest in the role of the pulmonary lymphatic system in the pathophysiology of pulmonary and systemic diseases induced us to carry out anatomical research on the lung lymphatic system in the Polish population. The aim of the study was to evaluate whether lymphatic vessels respect bronchopulmonary segment borders and to determine how often lymphatic vessels run to nodes of another lymphatic region. A block of organs comprising the lungs with the trachea, larynx and tongue, the heart and esophagus was removed from the cadavers at autopsy. The research involved 96 lungs (48 left and 48 right), which were taken from 31 m...

Structure and function of dendritic spines within the hippocampus.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Most excitatory input in the hippocampus impinges on dendritic spines. Therefore, the dendritic spines are likely to be of major importance for neural processing. The morphology of dendritic spines is very diverse and changes in spine size as well as in their density are thought to reflect changes in the strength of synaptic transmission. Thus, alterations in dendritic spine densities or shape are suspected to be morphological manifestations of psychopathological, pathophysiological, physiological and/or behavioural changes. However, in spite of a long history of research, the specific function of dendritic spines with...

Cataracta ossea - Ultrastructural and specimen analysis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Due to the small number of cases, the mechanisms and preconditions of osseous metaplasia of the lens are not understood in detail, but injury to the lens capsule and availability of blood supply are being discussed. Both were present in this case, in which the luxated lens ended up in the ciliary body region. The mechanism resembled enchondral ossification rather than intramembranous ossification, which is seen in osseous metaplasia of other intraocular structures.

Observations on the synaptic ribbon morphology in retinas of two human subjects at autopsy.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Retinal photoreceptor and bipolar cell axon terminals possess synaptic ribbons (SR) that aid in the trafficking of synaptic vesicles at active zones. In rodents, besides SR, a number of other synaptic elements [e.g., synaptic spheres (SS)] are known to appear when exposed to altered ambient illumination. Here, we report changes of ribbon shape in photoreceptor and bipolar cell axon terminals in retinas of two persons at autopsy who suffered from brain hemorrhage. In both subjects, retinal hemorrhage was present in the outer and inner nuclear layers. SR were bent or swollen and transformed into SS. A count revealed that...

Insights into the nature of human testicular peritubular cells.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Human testicular peritubular cells are myofibroblast-like cells that surround the seminiferous tubules and are responsible for tubular contractility and sperm transport. In the last few years, several reports have augmented this simplified view, showing that peritubular cells are not only structural cells but also actively secrete paracrine mediators, thereby influencing the homeostasis of the testicular environment. This review is focussed on general aspects and functions of testicular peritubular cells, their potential role in male infertility and also on the recently described in vitro culture systems of human testi...

Fascicles of the adult human Achilles tendon - An anatomical study.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The Achilles or calcaneal tendon is the structural base for the biomechanical work of the ankle joint. The purpose of this study is to describe the internal structure of the human Achilles tendon. The anatomy of the Achilles tendon has been described in lower mammals in which it has three parts which can be dissected from its beginning to the insertion onto the calcaneus. The partial ruptures of each part suggest that the human Achilles tendon may also be composed of parts. The Achilles tendon is one of the most commonly torn tendons in the human body. Each segment of the Achilles tendon described by us can be ruptured...

Expression of glucose transporter isoforms and the insulin receptor during hamster preimplantation embryo development.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
During preimplantation development, embryos of many species are known to express up to five isoforms of the facilitative glucose transporter proteins (GLUT). Development of hamster blastocysts is inhibited by glucose. We therefore investigated GLUT isoform and insulin receptor (IR) expression in hamster preimplantation embryos cultured in glucose-free medium from the 8-cell stage onwards. We show that GLUT1, 3 and 8 mRNA are constitutively expressed from the 8-cell to the blastocyst stage. The IR is expressed from the morula stage onwards. Messenger RNA of the insulin-responsive GLUT4 was not detected at any stage. GLU...

Cryo-electron tomography in biology and medicine.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
During the last six decades electron microscopy (EM) has been essential to ultra-structural studies of the cell to understand the fundamentals of cellular morphology and processes underlying diseases. More recently, electron tomography (ET) has emerged as a novel approach able to provide three-dimensional (3D) information on cells and tissues at molecular level. Electron tomography is comparable to medical tomographic techniques like CAT, PET and MRI in the sense that it provides a 3D view of an object, yet it does so at a cellular scale and with nanometer resolution. Electron tomography has the unique ability to visua...

Based on a large homogeneous sample from a Japanese population, anatomic variations in the celiac trunk (CT) and the hepatic artery were studied. Previously we analyzed the branching mode of the CT in 450 Japanese cadavers. In order to maximize the database on the CT and hepatic artery, we examined the anatomy of these arteries in 524 cadavers, a total of 974 cases. A total of 89.8% of cases showed the classical trifurcation of the CT. The typical normal pattern of the CT and the hepatic artery was confirmed in 66.6% and 72.4% of the cadavers, respectively. Variant left and right hepatic arteries were observed in 11.0%...

Activation and dedifferentiation of chondrocytes: Implications in cartilage injury and repair.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Cartilage injury remains a major challenge in orthopedic surgery due to the fact that articular cartilage has only a limited capacity for intrinsic healing. Cartilage impaction is followed by a post-traumatic inflammatory response. Chondrocytes and synoviocytes are activated to produce inflammatory mediators and degradative enzymes which can induce a progradient cartilage self-destruction finally leading to secondary osteoarthritis (OA). However, an anti-inflammatory compensatory response is also detectable in cartilage by up-regulation of anti-inflammatory cytokines, probably a temporary attempt by chondrocytes to res...

Recently, we examined one of the most perfectly preserved mummies of the Joseon Dynasty (1392-1910) ever found in Korea. The individual was an elderly man and a high-ranking general who had lived sometime during the 16th or 17th century in Korea. When computerized tomography (CT) radiographs were taken, a fracture line was observed on the left side of the mandible. A post-factum dissection also provided crucial clues to the cause of death. First of all, blood clots were still evident at the fracture site, indicating that the mandibular fracture had occurred just before death. Second, we also found feces exclusively in ...

Electrical stimulation of paralyzed vibrissal muscles reduces endplate reinnervation and does not promote motor recovery after facial nerve repair in rats.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The outcome of peripheral nerve injuries requiring surgical repair is poor. Recent work has suggested that electrical stimulation (ES) of denervated muscles could be beneficial. Here we tested whether ES has a positive influence on functional recovery after injury and surgical repair of the facial nerve. Outcomes at 2 months were compared to animals receiving sham stimulation (SS). Starting on the first day after end-to-end suture (facial-facial anastomosis), electrical stimulation (square 0.1ms pulses at 5Hz at an ex tempore established threshold amplitude of between 3.0 and 5.0V) was delivered to the vibrissal muscle...

Histology is a child of the 19th century, and its status in medicine was long in doubt. Was "microscopic anatomy" to be viewed as a refinement of the traditional discipline or as a technically complex subject of doubtful practical value?

Orientation of the rotator cuff insertion facets on the humerus: Comparison between individuals with intact and torn rotator cuffs.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The purpose of this work has been to compare the orientation of the rotator cuff insertions on the humerus between individuals with intact and torn rotator cuffs, respectively, to look for anatomical factors involved in the pathogenesis of rotator cuff tears. A total of 60 patients evaluated by arthro-computed tomography (CT) were divided into an intact rotator cuff group (31 patients) and a torn rotator cuff group (29 patients). The orientation angles of the lesser humeral tubercle facet and of the superior, middle and inferior facets of the greater humeral tubercle were measured in the sagittal plane between the hori...

Soluble and membranous vascular endothelial growth factor receptor-1 in pregnancies complicated by pre-eclampsia.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Vascular endothelial growth factor receptor-1 (VEGFR-1) is essential for the normal development and function of the placenta. Defective placental vasculogenesis and trophoblast function may lead to pre-eclampsia, a pregnancy-specific syndrome of hypertension and proteinuria. In order to study the association of VEGFR-1 with the development of pre-eclampsia, a cross-sectional study was carried out to evaluate the concentration of soluble VEGFR-1 (sVEGFR-1) in 360 serum samples and to analyze the expression of membranous VEGFR-1 in 40 placental samples of normal and pre-eclamptic pregnant women. Serum and placental sampl...

Bio-technologies for a glandular stem cell cardiomyopexy.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The glandular stem cell cardiomyopexy should become a treatment option for end-stage heart failure. It combines an expected regenerative potential of transformed adult glandular stem cells into cardiomyocytes within the myocardium or onto the myocardium of the recipient and the potential of a hypercapillarized latissimus dorsi muscle (LDM) wrapped around the heart for stem cell nutrition and girdling.

A study on the relationship between intraglandular arterial distribution and thyroid lobe shape: Implications for biotechnology of a bioartificial thyroid.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We have recently hypothesized that structural and secretory components of the adult human thyroid gland maintain constant reciprocal and geometrical relationships, even if changes occur in the three-dimensional (3D) architecture of any of these elements. This means that thyroid morphology could be studied from the point of view of a 3D topology. As a consequence, we have investigated anatomical aspects that could support this assumption. In the present study, we show that the presence of a constant relationship can be demonstrated between the vascular arrangement of the gland, including the extension of intraglandular ...

Controlling alpha-SMA expression in adult human pancreatic stem cells by soluble factors.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In the application of adult stem cells in regenerative medicine, it is indispensable to control stem cell behaviour in vitro. Since stem cells spontaneously differentiate into several cell types, it is mandatory to identify methods to enrich the desired cell types and concurrently block other differentiation pathways. More precisely, generation of a defined cell population is a key prerequisite for a therapeutic application of stem cells. Here we have demonstrated that it is possible to influence the differentiation of human pancreatic stem cells (hPSCs). During activation of mesodermal differentiation, the cytoskeleta...

Insights into the transcriptional and chromatin regulation of mesenchymal stem cells in musculo-skeletal tissues.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Utilizing adult stem cells for regenerative medicine of skeletal tissues requires the development of molecular and biochemical tools that will allow isolation of these cells and direction of their differentiation towards a desired lineage and tissue formation. Stem cell commitment and fate decision into specialized functional cells involve coordinated activation and silencing of lineage-specific genes. Transcription factors and chromatin-remodeling proteins are key players in the control process of lineage commitment and differentiation during embryogenesis and adulthood. Transcription factors act in cooperation with c...

Mesenchymal stem cells as a potential pool for cartilage tissue engineering.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Osteoarthritis (OA) resulting from trauma, degenerative or age-related disease presents a major clinical challenge due to the limited repair capacity of articular cartilage. This poor self-repair capacity of osteochondral defects has resulted in the development of a wide variety of new treatment approaches. Although the use of chondrocytes in applications of cartilage tissue engineering is still prevalent, concerns associated with donor-site morbidity, cell de-differentiation and the limited lifespan of these cells have brought the use of mesenchymal stem cells (MSCs) to the forefront of such applications. Therefore, i...

Magnetic resonance imaging of heterotaxis syndrome.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report on a 20-year-old young woman who presented to the emergency room with upper abdominal pain. On chest X-ray, dextrocardia was noted. Ultrasound was inconclusive. Barium studies demonstrated non-rotation of the intestine. Magnetic resonance imaging (MRI) of the abdomen confirmed heterotaxis with abnormal arrangement of abdominal organs and vasculature. This is the first radiographic description of LRA in MRI. It provides a unique contribution to the wide morphological variety of lateralization defects in a single examination within 15min and without the risks of ionizing radiation. In addition, a literature overvie...

Save this article to My Clippings. Discuss or comment on this article.
This study, showing decreased IGFBP4 in different brain regions of SOD1(G93A) transgenic mice, may provide clues to understanding the differential susceptibility of neural structures in ALS, suggesting a role of IGFBP4 in an abnormality of cognitive and/or motor function in ALS. The mechanisms and functional implications of these decreases require elucidation. PMID: 18823765 [PubMed - as supplied by publisher] (Source: Annals of Anatomy)
