Microbial Leakage through Three Different Implant-Abutment Interfaces on Morse Taper Implants In Vitro.

The objective of this study was to evaluate microbial leakage by means of genome counts, through the implant-abutment interface in dental implants with different Morse taper abutments. Fifty-six samples were prepared and divided in four groups: CMC TB (14 Cylindrical Implants-14 TiBase Abutments), CMX TB (14 Conical Implants-14 TiBase Abutments), CMX PU (14 Conical Implants-14 Universal Abutment) and CMX U (14 Tapered Implants-14 UCLA Abutments). Assemblies had their interface submerged in saliva as the contaminant.

Isoflurane anesthesia suppresses gastric myoelectric power in the ferret.

Background: Gastric myoelectric signals have been the focus of extensive research; although it is unclear how general anesthesia affects these signals, and studies have often been conducted under general anesthesia. Here, we explore this issue directly by recording gastric myoelectric signals during awake and anesthetized states in the ferret and explore the contribution of behavioral movement to observed changes in signal power.

Methods: Ferrets were surgically implanted with electrodes to record gastric myoelectric activity from the serosal surface of the stomach, and, following recovery, were tested in awake and isoflurane-anesthetized conditions.

Effect of elastomeric urethane monomer on physicochemical properties and shrinkage stress of resin composites.

Purpose: The aim of this randomized study was to examine the efficacy of two high intensity educational programs: the conversation maps-based (CM™) education and the individual education (IE), compared to usual care (UC) in a cohort of type 2 diabetic (T2DM) patients.

Methods: Ninety T2DM outpatients (30 per group) were randomized and 79 finished the study and were analyzed. The CM™ and IE groups received four educational sessions at 0, 4, 8 and 12 weeks, while the UC group received two brief individual sessions at 0 and 12 weeks.

Dentigerous cysts associated with impacted third molars in adults after decompression: a prospective survey of reduction in volume using computerised analysis of cone-beam computed tomographic images.

We prospectively investigated in adults the decompression of dentigerous cysts associated with impacted third molars at high risk of iatrogenic damage during extraction. The computerised calculated volumetric postoperative reductions measured by cone-beam computed tomography at four and eight months were correlated with the duration of treatment, initial volume, and patient's age. We prospectively monitored 14 adult patients with 14 dentigerous cysts that were associated with impacted third molars, for eight months after decompression.

Integrated insulin pump therapy with continuous glucose monitoring for improved adherence: technology update.

Insulin pump therapy combined with real-time continuous glucose monitoring, known as sensor-augmented pump (SAP) therapy, has been shown to improve metabolic control and to reduce the rate of hypoglycemia in adults with type 1 diabetes compared to multiple daily injections or standard continuous subcutaneous insulin infusion. Glycemic variability is also reduced in patients on SAP therapy. This approach allows patients to monitor their glucose levels being informed of glycemic concentration and trend.

Efficacy of real-time continuous glucose monitoring on glycaemic control and glucose variability in type 1 diabetic patients treated with either insulin pumps or multiple insulin injection therapy: a randomized controlled crossover trial.

Background: The aim of this study was to determine the efficacy of real-time continuous glucose monitoring in T1D patients treated with insulin pump therapy or multiple daily insulin therapy.

Methods: Twenty adult patients (ten insulin pump therapy and ten multiple daily insulin) with poor glycaemic control (HbA1c  > 8.0%) were randomized into two groups for 6 months: the continuous glucose monitoring arm (using real-time continuous glucose monitoring) and the SMBG arm.

Healing of chronic necrobiosis lipoidica lesions in a type 1 diabetic patient after pancreas-kidney transplantation: a case report.

Necrobiosis lipoidica (NL) is a degenerative disease of dermal connective tissue of unknown etiology characterized by erythematous plaques preferentially localized to distal extremities. Skin lesions show a chronic relapsing nature. NL is often associated with diabetes mellitus and satisfactory treatment options are lacking.

Diabetic mastopathy: a case report.

Diabetic mastopathy, although reported since 1984, is a poorly recognized diabetes complication. It more frequently affects pre-menopausal women with Type 1 diabetes mellitus and microvascular complications. The pathogenesis of this condition is believed to involve mammary tissue autoimmune reaction to the accumulation of abnormal matrix proteins, caused by hyperglycemia.

The estimated completeness of our register was 99.2%.

Detection and characterization of biodeteriogens on stone cultural heritage by fluorescence lidar.

Biodeteriogens are an important cause of the weathering of a monument, particularly those made of stone, and their detection at an early stage of development helps to protect the monument from deterioration. Frequent mapping of biodeteriogen accumulation is therefore highly necessary. The use of fluorescence lidar for this purpose was introduced in 1995 and has been developed in subsequent years.

Regulation of norepinephrine in the medial preoptic area of Siberian hamsters by gonadal steroids.

Photoperiod has profound effects upon the neuroendocrine axis underlying reproductive physiology in seasonally breeding mammals. For long-day (LD) breeders, such as the Siberian hamster, exposure to a short-day (SD) photoperiod results in declines in circulating levels of gonadal steroids, luteinizing hormone (LH), and prolactin (PRL). The current study sought to investigate the effects of photoperiod and steroid levels on norepinephrine (NE), one of the major neurochemical regulators of gonadotropin-releasing hormone (GnRH) function.

Genotypic diversity and typing of cyanobacterial strains of the genus Arthrospira by very sensitive total DNA restriction profile analysis.

Arthrospira maxima and A. platensis are two species of cyanobacteria cultivated and sold as health food, animal feed and source of food additives and fine chemicals. The genotypic diversity of several strains attributed to these two species on the basis of morphological criteria was investigated using very sensitive total DNA restriction profile analysis.

Phototrophic biodeteriogens on lithoid surfaces: An ecological study.

For two strains, the green alga Pleurococcus CVB4 and the cyanobacterium Lyngbya CCB2, isolated from the pioneering algal biocoenosis present on a marble statue, we determined the optimum range of growth in selective cultural media in relation to pH, light intensity, and temperature, together with the ability of these organisms to colonize stone surfaces that differed either in the structure-texture or in the physico-chemical composition of the various lithotypes. The results showed a higher capacity of the green alga to withstand environmental factor changes. For both organisms the preferential colonization of the stone surface was correlated primarily, together with the environmental factors (pH, temperature, irradiance), to the physical characteristics (roughness and porosity) and secondarily to the chemical composition of the assayed lithotypes.

Incidence of type I diabetes in the district of Catania, Sicily.

The incidence of type I (insulin-dependent) diabetes was determined in the district of Catania (eastern Sicily) in children under 15 years of age over a 3-year period (1 January 1989 to 31 December 1991). Two independent sources of information were used. The primary source was contact with all medical services in the province, and the secondary source was the personal identification cards issued to all diabetic patients by the National Health System necessary for obtaining free medical care.

Survival of diazotrophic cyanobacteria in soil.

The survival under drough conditions for one year of 12 heterocystous cyanobacterial strains inoculated in three different soil types (silt clay, calcareous clay and silt loam) gave the highest survival (50%) forScytonema 208L.Fischerella 288L andNostoc OP25 also showed significant survival. Moreover, the soils inoculated withFischerella 288L andScytonema 208L had a higher total N content than non-inoculated soils.
