The objective of this study was to evaluate the bond strength of fiberglass posts (Reforpost ®) cemented with RelyX U200 and RelyX Luting 2, with (A) and without (WA) ultrasonic activation in the root canal of bovine teeth. The penetration of the cements into dentine tubules was also assessed. Methods: Forty bovine incisors were selected and endodontically treated, and then divided into 4 groups (n = 10). Fiberglass posts were cemented with RelyX U200 and RelyX Luting 2 and activated with an ITSMO ultrasound insert in 2 groups; the other two groups received no ultrasonic activation. After 24 hours of cementation, the roots were sectioned into slices of approximately 1 mm each. Confocal microscopy and push-out test were performed, and all specimens were subjected to 200× magnification optical microscopy for mode of failure evaluation. Statistical analysis was done with three-way ANOVA, followed by the Fisher’s test (α = 0.05)

Hydatid disease is an important emerging neglected disease worldwide, with significant geographic variation in seroprevalance. The disease is commonly diagnosed on basis of clinical suspicion, imaging and serology. This study was conducted to evaluate our experience with serology in diagnosing hydatid disease in terms of identifying the numbers of patients testing positive for antibodies against Echinococcus, and to study their clinical profile.

MicroscopyStevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a disease continuum of potentially life threatening, severe allergic drug reactions which result in cellular apoptosis in the skin, mucous membranes, and ocular surface. The exact pathophysiologic mechanisms leading to this apoptosis is unclear but genetic predisposition and abnormal immune regulations play a role.

A translucent UV protecting poly (methyl methacrylate) (PMMA)/TiO2 nanocomposite has been fabricated using anatase TiO2 nanoparticles by solution method. The myristic acid capped titania nanoparticles were synthesized via a simple sol-gel method, involving hydrolysis of titanium tetra isopropoxide (TTIP).

Titanium dioxide (TiO2) (<100 nm) has been widely used in the production of paints, paper, and plastics, as well as in food additives and colorants .It has been classified as biologically inert in both humans and animals. Here we studied the toxicity of TiO2 on Wister rat. Main exposure area of NPs is caudal vein of Wistar rat.

Here we describe the case of a 35 year old male, with a harmonic phenotype, who sought medical assistance to assess the etiology of his infertility. As a result of clinical examination, karyotyping, FISH and molecular studies, we obtained the following karyotype: mos 45,X[18]/46,XY,idic(Y)q(11.2)[82]. Furthermore, the Y chromosome was characterized by the absence of the regions AZF2 (former AZFb, within the 11.22 band, and AZFc, within the 11.23 band), whereas the region AZF1 was conserved. Male infertility can be caused by several genetic alterations.

Anodisation of pure titanium has been carried out in sulphuric and in phosphoric acid solutions at potentials ranging from 50 to 150V. The SEM and AFM morphological analysis indicates that, within this potential range, oxidation in sulphuric acid solution produces better developed mesoporous oxide layers.

Vertical Cu2ZnSnS4 (CZTS) nanowire arrays have been synthesized via two-step electroplating method into anodized aluminum oxide template. For deposition of CZTS nanowires, anodized aluminum oxide (AAO) was used as the growth mask for the growth of the nanowires. AAO templates with hole sizes of 70 nm in diameter were used in the experiments.

In this paper, we report on the synthesis of BaTiO3 nanowires via the anodic aluminum oxide template method. To fill in the precursors of BaTiO3 into anodic aluminum oxide templates, the vacuum and drop loading method developed in our previous study was used. Ba(CH3COO)2 (barium acetate) and C12H28O4Ti (tetraisopropyl orthotitanate) were used as Ba and Ti sources, respectively. Anodic aluminum oxide membranes with the through-hole diameter of ~200 nm were used as the template for BaTiO3 nanowires.
