Purpose/aim: To examine with immunohistochemical assay MTA1 protein expression levels in pancreatic cancer tissues defining its prognostic value. MATERIAL AND METHODS: The specimens derived from 51 patients who underwent surgery. The levels of MTA1 protein were compared with the age of the patients, their survival, and prognosis. Also, we studied clinical and histopathological factors such as the degree of tumor differentiation and its stage in correlation with MTA1 protein levels. In parallel, there was correlation between the expression of the ΜΤΑ1 protein and the aforementioned factors regarding survival rate...

AIM: The aim of this study was to investigate the inclusion of silver nanoparticles (Ag NPs) in the mineral trioxide aggregate (MTA) composition to know which changes will result in the radiopacity of the material. MATERIALS AND METHODS: The experiment was performed according to the American National Standard Institute/American Dental Association specification no. 57/2000 and ISO 6876/2001. Five plates with five holes measuring 1 mm in depth and 5 mm in internal diameter were filled according to the different experimental groups as follows: white mineral trioxide aggregate (WMTA) + NP50 - W MTA with liquid Ag NP 50 ppm, WMTA + NP30 - W MTA with liquid Ag NP 30 ppm, WMTA + NP22 - W MTA with liquid Ag NP 22 ppm, WMTA + NPP - white MTA with liquid Ag NP and powder 1%, WMTA (control)...

OBJECTIVE: Qualitative interviews with 183 young adults (YA) in the follow-up of the Multimodal Treatment Study of Children With and Without ADHD (MTA) provide rich information on beliefs and expectations regarding ADHD, life's turning points, medication use, and substance use (SU). METHOD: Participants from four MTA sites were sampled to include those with persistent and atypically high SU, and a local normative comparison group (LNCG). Respondents were encouraged to "tell their story" about their lives, using a semistructured conversational interview format...

Microtubule-targeting agents (MTAs) are some of the clinically most successful anti-cancer drugs. Unfortunately, instances of multidrug resistances to MTA have been reported, which highlights the need for developing MTAs with different mechanistic properties. One less explored class of MTAs are [1,2,4]triazolo[1,5-a]pyrimidines (TPs). These cytotoxic compounds are microtubule-stabilizing agents that inexplicably bind to vinblastine binding site on tubulin, which is typically targeted by microtubule-destabilizing agents...

INTRODUCTION: Over the past many years various root end filling materials have been used which have been tested for their physical properties but each of them had certain limitations. In clinical practice, root end filling materials are exposed to oral tissue fluids which may compromise their longevity. AIM: The aim of this study was to investigate the effects of oral tissue fluids on compressive strength of Mineral Trioxide Aggregate (MTA) and biodentine. MATERIALS AND METHODS: MTA and biodentine cylinders measuring 6 mm × 4 mm were prepared using acrylic blocks...

tRNA molecules undergo extensive modifications during their maturation process and these modifications play important cellular roles. TrmL is a tRNA-modification enzyme that catalyzes the transfer of a methyl group to the 2' hydroxyl group of the pyrimidines at the wobble position 34 in two tRNA(L)(eu) isoacceptors, but the mechanism remains elusive. In this study, we determined the crystal structure of TrmL from Thermus Thermophilus (TtTrmL) to 1.7 Å. The enzyme contains only the conserved minimal SPOUT fold, but displays distinct biochemical behaviors from its Escherichia coli counterpart EcTrmL...

BACKGROUND/PURPOSE: Bioaggregates such as Portland cement (PC) can be an economical alternative for mineral trioxide aggregate (MTA) with additional benefit of less discoloration. MTA has been known to induce differentiations of several dental cells. MicroRNAs are important regulators of biological processes, including differentiation, physiologic homeostasis, and disease progression. This study is to explore how PC enhances the differentiation of periodontal ligament (PDL) cells in microRNAs level...

BACKGROUND: During the apexification procedure for teeth with open apices, mineral trioxide aggregate (MTA) may be unintentionally extruded. The aim of the present study was the retrospective evaluation of the healing of periapical lesions in permanent incisor teeth with open apices after the unintentional extrusion of MTA. METHODS: The clinical and radiographic records of 55 maxillary permanent central teeth treated by MTA apexification were evaluated. Filled teeth with unintentionally extruded MTA were selected as group 1 (n = 21), whereas the teeth with no MTA extrusion were selected as group 2 (n = 34)...

BACKGROUND: The identification and introgression of major-effect QTLs for grain yield under drought are some of the best and well-proven approaches for improving the drought tolerance of rice varieties. In the present study, we characterized Malaysian rice germplasm for yield and yield-related traits and identified significant trait marker associations by structured association mapping. RESULTS: The drought screening was successful in screening germplasm with a yield reduction of up to 60% and heritability for grain yield under drought was up to 78%...

An important challenge in neuronal tissue engineering is to create innovative tools capable of promoting cellular response in terms of neuronal differentiation and neurite orientation that may be used as investigational platforms for studying neurobiological events and neurodegenerative disorders. A novel membrane bioreactor was created to provide a 3D well-controlled microenvironment for neuronal outgrowth. The bioreactor consisted of poly-L-lactic acid highly aligned microtube array (PLLA-MTA) membranes assembled in parallel within a chamber that establish an intraluminal and an extraluminal compartment whose communication occurs through the pores of the MTA membrane walls...

Teeth with open apices, such as in immature teeth or those with apical root resorption are clinical cases with difficult immediate resolution. With the use of mineral trioxide aggregate (MTA) in dentistry, it was possible to optimize the treatment time of these cases by immediate placement of apical plug and the root canal filling. However, some negative effects can occur if MTA is extruded beyond the apex. To avoid this accident, it has been recommended to use of an apical matrix prior to placement of MTA...
