The developing chick limb has the remarkable ability to regulate for the loss of large amounts of mesenchyme and maintain a normal limb pattern in early (Hamburger and Hamilton Stage 19; E3) limbs. How the limb can regulate for tissue loss and why this ability is lost as development proceeds (aft...

In the last decade, diffusion tensor imaging (DTI) has been used increasingly to investigate three-dimensional (3D) muscle architectures. So far there is no study that has proved the validity of this method to determine fascicle lengths and pennation angles within a whole muscle. To verify the DT...

KPC-2 β-lactamase demonstrates a wide substrate spectrum that includes carbapenamases, oxyimino-cephalosporins, and cephamycins. In addition, strains harboring KPC-type β-lactamases are often identified as resistant to standard β-lactamase inhibitors. Thus, KPC-2 carbapenems present a signific...

Enzymes involved in the pyrimidine biosynthesis pathway have become an important target for the pharmacological intervention. One among those enzymes, Aspartate Trans Carbamoylase (ATCase), catalyses the condensation of aspartate and carbamoyl phosphate to form N-carbamoyl-l-aspartate and inorgan...

Using the double immunostaining method, the glia limitans on the surfaces of mouse and monkey brain and spinal cord were studied systematically. The results showed that the superficial glia limitans of mouse brain and spinal cord comprise a layer of surface astrocytes, while the glia limitans of ...

The skull is considered a modular structure in which different parts are influenced by different factors and, as a result, achieve adult shape at different ages. Previous studies have suggested that the basicranium presents a modular pattern that distinguishes sagittal and lateral parts, probably...

German anatomical institutes had always had problems obtaining sufficient cadavers for research and training. In the National Socialist (NS) period this changed. Universities could count on “extraordinary opportunities for cadaver delivery”. Most frequently tacitly, many bodies were those of ...

The aim of this study was to provide data on various dimensions of the normal cochlea using three-dimensional reconstruction based on high-resolution micro-CT images. The petrous parts of 39 temporal bones were scanned by micro-computed tomography (CT) with a slice thickness of 35 μm. The micro-...

Nerve fibers contributing to the superior hypogastric plexus (SHP) and the hypogastric nerves (HN) are currently considered to comprise an adrenergic part of the autonomic nervous system located between vertebrae (T1 and L2), with cholinergic aspects originating from the second to fourth sacral s...

Cutaneous scarring is currently an inevitable outcome following skin injury. Abnormal pigmentation within scars makes them more noticeable, causing distress for patients, particularly as there is no reliable and effective treatment available to date. The Duroc pig, known to scar badly, was used t...

Although the ovine spine is a useful research model for intervertebral disc pathology and vertebral surgery, there is little peer-reviewed information regarding the MRI anatomy of the ovine spine. To describe the lumbar spine MRI anatomy, 10 lumbar segments of cadaver ewes were imaged by 1.5-Tesl...

The present study clarifies developmental organization of the oxytalan fiber system in the periodontal space of both the enamel (labial) and cementum (lingual) sides of rat incisors. The number of oxytalan fibers per unit area (μm2) was counted in rat incisors at stages of embryonic day 20 (E20)...

The binding of ciprofloxacin to lysozyme in the presence of three Ag nano-particles of varying sizes was for the first time investigated by multispectroscopic and isothermal titration calorimetry techniques at pH 7.4. The results indicated that ciprofloxacin quenched the fluorescence intensity of...

The metameric pattern of the axial skeleton is established during embryogenesis by somite formation from the unsegmented paraxial mesoderm (presomitic mesoderm). Here, we have investigated the morphology of the anterior presomitic mesoderm of chick embryos using scanning electron microscopy. We f...

Periodontal ligament (PDL) cells, a major component of the tooth supporting apparatus, share osteoblastic characteristics including their responsiveness to parathyroid hormone (PTH). Clinical studies have already pointed to the benefit of PTH in supporting regenerative processes in the craniofaci...
