In order to avoid both natural and artificial stone decay, mainly due to the interaction with atmospheric pollutants (both gases such as NOx and SO2 and particulate matter), polymeric materials have been widely studied as protective coatings enable to limit the penetration of fluids into the bulk material. In the current work, an air hardening calcic lime mortar (ALM) and a natural hydraulic lime mortar (HLM) were used as substrates, and commercially available Si-based resins (Alpha®SI30 and Silres®BS16) were adopted as protective agents to give hydrophobicity features to the artificial stones...

BACKGROUND/AIM: To study the characteristics of interleukin 6 (IL6), soluble form of interleukin 6 receptor (sILR)/IL6 complex in obese children and adolescents and its relationship with insulin resistance (IR). SUBJECTS AND METHODS: 66 obese children and adolescents [34 boys, mean age 10.3 ± 2.9 years, z-score of body mass index (BMI) 4.76 ± 1.36] and 24 non-obese healthy sex- and age-matched controls. Fasting levels of glucose, insulin, IL6, sIL6, sgp130 were measured...

Pigment epithelium-derived factor (PEDF) has anti-inflammatory and anti-thrombogenic properties both in cell culture and animal models. Although adipose triglyceride lipase (ATGL) and laminin receptor (LR) are two putative receptors for PEDF, which receptor mainly mediates the beneficial effects of PEDF is largely unknown. In this study, we addressed the issue. siRNA raised against LR (siLR) and siATGL transfection dramatically decreased LR and ATGL levels in human cultured myeloma cells, respectively. Ten nM PEDF significantly reduced vascular endothelial growth factor (VEGF), monocyte chemoattractant protein-1 (MCP-1), intercellular cell adhesion molecule-1 (ICAM-1) and plasminogen activator inhibitor-1 (PAI-1) mRNA levels in siCon- or siATGL-transfected myeloma cells, whereas PEDF increased rather than decreased these gene expressions in siLR-transfected cells...

Menopause is the transitional event of female life creating a considerable degree of clinical and psychological as well as social problem and it is known to affect the risk markers of cardiovascular diseases. Hormone replacement therapy (HRT) was though to be a cornerstone in the management of menopause, but evidences accumulated in the recent past have raised serious questions regarding its safety and usability. In this context, phytoestrogens are getting increasingly more attention for therapeutic (as an alternate of HRT) and dietary interventions...

The aim of this study was to investigate the prevalence of silver resistance genes in 172 bacterial strains which had been isolated from both human and equine wounds. PCR screening for 8 currently named genes in 3 silver resistance transcriptional units, silE, silRS and silP, silCBA and silF was performed on total DNA extracted from all clinical isolates. Plasmids were isolated from sil-positive strains to determine if the genes were present on the chromosome. MICs and zone of inhibition assays were utilised to examine phenotypic resistance to silver nitrate and ionic silver...

Bacterial resistance to Ag(I) has been reported periodically with isolates from many environments where toxic levels of silver might be expected to occur, but initial reports were limited to the occurrence of resistant bacteria. The availability of silver-resistance conferring DNA sequences now allow genetic and mechanistic studies that had basically been missing. The genes determining Ag(I) resistance were sequenced from a plasmid found in a burn ward isolate. The 14.2 kb determinant contains seven recognized genes, arranged in three mRNA transcriptional units...

BACKGROUND: Proinflammatory cytokines are important mediators in heart failure (HF). Recently, urinary levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) have been determined. AIMS: The purpose of this study was to measure the urinary levels of TNF-alpha and IL-6 receptors, sTNF-RI, sTNF-RII, sIL-6R, and the relationship with plasma levels and NYHA classes in HF. METHODS: Plasma and urine were collected from 114 HF patients and sTNF-RI, sTNF-RII and sIL-6R (ng/ml) were analyzed...

Simon Silver
Resistance to silver compounds as determined by bacterial plasmids and genes has been defined by molecular genetics. Silver resistance conferred by the Salmonella plasmid pMGH100 involves nine genes in three transcription units. A sensor/responder (SilRS) two-component transcriptional regulatory system governs synthesis of a periplasmic Ag(I)-binding protein (SilE) and two efflux pumps (a P-type ATPase (SilP) plus a three-protein chemiosmotic RND Ag(I)/H+ exchange system (SilCBA)). The same genes were identified on five of 19 additional IncH incompatibility class plasmids but thus far not on other plasmids...

Silver compounds are used as antimicrobial agents in medicine and bacteria that develop resistance to silver cations (Ag(+)) pose problems similar to those of antibiotic-resistant bacteria. The first set of Ag(+) resistance genes (sil) was from plasmid pMG101, now assigned to the IncHI incompatibility group. Questions of whether sil genes are unique to pMG101 or are more widely found, and whether they are associated with a specific incompatibility group or occur in many plasmid groups and on bacterial chromosomes were addressed...

Using a genetic screen we have identified two chromosomal genes, cusRS (ylcA ybcZ), from Escherichia coli K-12 that encode a two-component, signal transduction system that is responsive to copper ions. This regulatory system is required for copper-induced expression of pcoE, a plasmid-borne gene from the E. coli copper resistance operon pco. The closest homologs of CusR and CusS are plasmid-borne two-component systems that are also involved in metal responsive gene regulation: PcoR and PcoS from the pco operon of E...

Here we report the genetic and proposed molecular basis for silver resistance in pathogenic microorganisms. The silver resistance determinant from a hospital burn ward Salmonella plasmid contains nine open reading frames, arranged in three measured and divergently transcribed RNAs. The resistance determinant encodes a periplasmic silver-specific binding protein (SilE) plus apparently two parallel efflux pumps: one, a P-type ATPase (SilP); the other, a membrane potential-dependent three-polypeptide cation/proton antiporter (SilCBA)...

396 patients, treated with hemorrhoidectomy (278 Parks, 118 Milligan-Morgan) were submitted to preoperative manometry, which, in 158 patients (39.9%), revealed high anal resting pressure (TBS), with or without an associated anal fissure; this group was submitted to a regulated lateral sphincterotomy (SILR) in association with the haemorroidectomy. The manometric follow-up, two mounts after the operations showed similar TBS values in both groups of patients. The authors conclude that normal values of TBS after Hemorroidectomy can be reached only by associating sphincterotomy in manometrically selected cases...

Laboratory parameters which are modified following administration of zidovudine are becoming increasingly useful in monitoring the efficacy of treatment of early stages of HIV-1 infection. The serum levels of soluble interleukin (sILR)-2 receptor, which have been reported to increase early in HIV-1 infection, were found to be significantly lower in 24 patients being treated with zidovudine than in 69 patients who were not treated, 28 of whom had CD4+ counts greater than 400 x 10(6)/l, and 41 less than 400 x 10(6)/l, respectively (P less than 0...
