Particulate matter (PM), a major air pollutant has been demonstrated to cause intracellular inflammation by inducing reactive oxygen species (ROS) generation in human keratinocytes. Although PM shown be associated with various skin disorders, including atopic dermatitis, eczema, and aging, there have few studies on the effect of hairs. The aim this study was investigate potential role oxidative...

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open a...

This research was conducted to analyze the hardness, microstructural morphology, and crystallography of MgB2 compound in form a SS 304-sheathed superconducting wire. wire with 304 outer sheath manufactured using an ex-situ rolling process. The results Vickers hardness test load 0.3 N showed value 355.1 HV. observations SEM-EDS (scanning electron microscopy-energy dispersive spectroscopy) agglom...

The Pacinian corpuscle has a framework of cytoplasmic lamellae arranged concentrically in the outer zone, and bilaterally in the core. Between these is an intermediate growth zone. The inner core shows an unexpected complexity in that its component lamellae are arranged in two symmetrical groups of nested cytoplasmic sheets. Longitudinal tissue spaces form clefts separating the two groups. The ...

Kinetics of phospholipid constituents transferred from the axon to the myelin sheath were studied in the oculomotor nerve (OMN) and the ciliary ganglion (CG) of chicken. Axons of the OMN were loaded with transported phospholipids after an intracerebral injection of [2-all]glycerol or Jail]labeled choline. Quantitative electron microscope radioautography revealed that labeled lipids were transpo...

0305-7364/0 * For corre { Present Durham, NC Paspalum dilatatum occupies di€erent topographic positions in the Flooding Pampa, Argentina. Populations from di€erent positions are subjected to various regimes of ̄ooding and drought, both of which may occur in the same growing season. We investigated the constitutive and plastic anatomical traits of P. dilatatum populations from habitats with contr...

We read with interest Luzardo et al’s technical note in the December issue of the AJNR. Although we are pleased that the new Envoy 6F guide catheter (Cordis, Miami Lakes, Fla) facilitated a dualmicrocatheter procedure with a single arterial access, it should be noted that this is by no means a new technique. The 6F Envoy guide catheter with an inner diameter of 0.070 inches and outer diameter o...

root resorption (rr) is defined as the loss of dental hard tissues because of clastic activity inside or outside of tooth the root. in the permanent dentition, rr is a pathologic event; if untreated, it might result in the premature loss of the affected tooth. several hypotheses have been suggested as the mechanisms of root resorption such as absence of the remnants of hertwig's epithelial root...

Here we present the case of a 36-year-old man who was found to have a symptomatic malignant neural sheath tumor growing from the C2 nerve root following a period of progressively worsening headaches. The patient was successfully treated with surgical resection resulting in resolution of cranial nerve deficits. Though uncommon, malignant peripheral nerve sheath tumor must be considered in the di...
