OBJECTIVES The formation of biofilm around implants, which is induced by immediate bacterial colonization after installation, is the primary cause of post-operation infection. Initial surface modification is usually required to incorporate antibacterial agents on titanium (Ti) surfaces to inhibit biofilm formation. However, simple and effective priming methods are still lacking for the developm...

The separability problem for word languages of a class C by languages of a class S asks, for two given languages I and E from C, whether there exists a language S from S that includes I and excludes E, that is, I ⊆ S and S ∩E = ∅. In this work, we assume some mild closure properties for C and study for which such classes separability by a piecewise testable language (PTL) is decidable. We chara...

Purpose: To compare the complications and survival rate after different treatment modalities of advanced laryngopharyngeal cancer. Methods: Retrospective study included 619 advanced laryngopharyngeal carcinoma, treated with either primary total laryngectomy (PTL), or salvage (STL) after partial laryngectomy, radio, chemoradiotherapy. Complications and survival rate were documented. Results: Fiv...

We discuss the problem of constructing PT-nets with localities (PTL-nets) from transition systems with arcs labelled by multisets of transitions (steps). We first outline how this can be done within the existing general solution based on the regions of step transition systems and fixed co-location relations. We then drop the latter assumption and show that this does not really matter when one a...

Magnitude comparison is one of the basic functions used for sorting in microprocessor, digital signal processing, so a high performance, effective magnitude comparator is required. The main objective of this paper is to provide new low power, area solution for Very Large Scale Integration (VLSI) designers. At circuit level, Hybrid PTL/CMOS Logic style gives best results over CMOS only and PTL o...

Papillary thyroid cancer (PTC) represents 80-85% of thyroid cancer and its prevalence has been rising in the last decades. Primary thyroid lymphoma (PTL) accounts for 3% of extranodal lymphomas and about 5% of thyroid malignancies, having a prevalence of one or two cases per million people. Mucosa-Associated Lymphoid Tissue lymphoma represents approximately 30% of PTL. Both entities have an ind...

Primary testicular lymphoma (PTL) is a rare, clinically aggressive form of extranodal lymphoma. The vast majority of cases are histologically diffuse large B-cell lymphoma, but rarer subtypes are clinically important and must be recognized. In this review, we discuss the incidence, clinical presentation, and prognostic factors of PTL and present a summary of the recent advances in our understan...

This study aimed to determine the mechanism of uterine activation during labour, both term (TL) and preterm (PTL). We hypothesized that the peripheral leucocytes are recruited to uterine tissues by locally produced cytokines where they contribute to the initiation of parturition. Mouse uteri were collected (i) during gestation, TL and post-partum (PP), (ii) during PTL initiated by intrauterine ...

We previously reported a two-step biochemical diagnosis to discriminate classic 21-hydroxylase deficiency (C21OHD) from P450 oxidoreductase deficiency (PORD) by using urinary steroid metabolites: the pregnanetriolone/tetrahydrocortisone ratio (Ptl / the cortisol metabolites 5α- and 5β-tetrahydrocortisone (sum of these metabolites termed THEs), and 11β-hydroxyandrosterone (11OHAn). The objective...
