With the invention of new techniques and modalities “see and treat” has become the norm of management now a days. Diagnostic hysteroscopy combined with histological examination of an endometrial biopsy is considered the ‘gold standard’ in the diagnosis of intrauterine abnormalities. The importance of office hysteroscopy lies in the fact that there is no need of any anesthesia and after the procedure the patient can return into his routine activity only with the minimal aid of NSAIDs. Two different types of hysteroscopes are used worldwide: flexible or rigid, which are made in different sizes. Optic miniaturization has been one of the greatest technological advancements in the field of hysteroscopy, both for rod-lens and fiberoptic scopes. The main concerns in office hysteroscopy are the need for necessary expertise, pain management and management of the complications in the office setting and the high cost of the equipment needed for the procedure. But office hysteroscopy has already demonstrated good correlation of findings compared with inpatient hysteroscopy, providing distinct advantages such as reduced anesthesia risks, enhanced time and cost-effectiveness, and faster recovery with less time away from work and home.

Abstract. Noise studies of planar thin-film Ni-P resistors made in/on Printed Circuit Boards, both covered with two different types of cladding or uncladded have been described. The resistors have been made of the resistive-conductive-material (Ohmega-Ply©) of 100 Ώ/sq. Noise of the selected pairs of samples has been measured in the DC resistance bridge with a transformer as the first stage in a signal path. 1/f noise caused by resistance fluctuations has been found to be the main noise component. Parameters describing noise properties of the resistors have been calculated and then compared with the parameters of other previously studied thin- and thick-film resistive materials.

Abstract Background Idiopathic Pulmonary Fibrosis (IPF) is a degenerative interstitial lung disease with both a poor prognosis and quality of life once the diagnosis is made. In the last decade many features of the disease have been investigated to better understand the pathological steps that lead to the onset of the disease and, moreover, different types of biomarkers have been tested to find valid diagnostic, prognostic and therapy response predictive ones. In the complexity of IPF, microRNA (miRNAs) biomarker investigation seems to be promising. Methods We analysed the expression of five exosomal miRNAs supposed to have a role in the pathogenesis of the disease from serum of a group of IPF patients (n = 61) and we compared it with the expression of the same miRNAs in a group of healthy controls (n = 15). Results In the current study what emerged is let-7d down-regulation and, unexpectedly, miR-16 significant down-regulation. Moreover, through a cross-sectional analysis, a clustering of the expression of miR-16, miR-21 and miR-26a was found. Conclusions These findings could help the individuation of previously unknown key players in the pathophysiology of IPF and, most interestingly, more specific targets for the development of effective medications.

Abstract Despite the well-established benefits of social participation for individuals and communities, little is known about how it varies throughout the life course. Drawing upon data collected between 1957 and 2011 by the Wisconsin Longitudinal Study (22,023 observations from a cohort of 6,627), this study provides four valuable results. One, I find evidence of five distinct social participation trajectories between the ages of 35 and 71; the majority of which demonstrate social disengagement over time. Two, these participation declines are primarily attributable to changes in meeting friends and group exercise activity. Three, the most pronounced activity differences separating those in more favorable and unfavorable participation trajectories are cultural event attendance and voluntary group membership. Lastly, I identify particular high school activities that are associated with social participation decades later. In total, these results highlight heterogeneity among different types of social activities, and underscore the possible consequences of membership decisions made in early adulthood.

The DNV-RP-C203 Fatigue Design of Offshore Steel Structures is being used by a number of different companies for fatigue assessment of different types of structures. This has resulted in questions to DNV about background for the different sections in the document. It is therefore important that the basis for this document is open to the industry. Quite a lot of the background material has also been published earlier at conferences and in journals. In some situations it has been found that the content can be improved to better suite the industry. The document is presented in an electronic version making revisions easy. Therefore it has been revised several times since the last official presentation of a revision in 2005. The present paper gives an overview of the most significant changes made in the document since the 2005 revision. Some of these changes are already included in the present version of DNV-RP-C203. The remaining changes will be included in a revision dated 2010.

Enormous progress has been made in the last few years towards the elucidation of the mechanism of protein synthesis, and great interest is centred on the steps leading to cellular differentiation and specific protein synthesis. We know that genetic information is passed on from one generation of cells to the next by deoxyribonucleic acid (DNA), and that this material directs all protein synthesis by the intermediary of the different types of ribonucleic acid (RNA). A simple in vitro system described by O'Brien (1959) seemed to offer an excellent tool for the study of the differentiation of the blood islands, and the initial formation of a well-known protein, haemoglobin (Hb), in chick embryonic tissues. After de-embryonation, chick blastoderms, from the stage of primitive streak onwards, can be cultured in vitro on a saline agar medium supplemented with glucose.

Manufacturers offer different types of ballistic barrels made in according to various standards. The paper presents comparison of three types of ballistic barrels: pressure, velocity and accuracy made according to C.I.P. and NATO EPVAT standards. Projectile velocities in a several measuring points on the flight path and propellant gas pressures in the barrels were measured and compared. The main aim of the article is to discuss whether all types of barrels to conduct most ballistic tests are needed, or whether one, the most universal in a specific caliber is enough.

ABSTRACT Antimicrobial susceptibility testing (AST) provides critical information for the management of patients with infections. The gold standard methods for assessing organism susceptibility are still based on growth and require incubation over relatively long periods of time. Until now, little progress has been made in developing rapid, growth-based, phenotypic AST systems. This commentary puts the recently FDA-cleared Accelerate PhenoTest (P. Pancholi et al., J Clin Microbiol 56:e01329-17, 2018, https://doi.org/10.1128/JCM.01329-17) in context by providing a historical perspective on attempts to accelerate phenotypic susceptibility results. In addition, some promising new innovations that promise to shorten the turnaround time for phenotypic AST will be briefly reviewed.

SUMMARYThe study of Escherichia coli and its plasmids and bacteriophages has provided a vast body of genetical information, much of it relevant to the whole of biology. This was true even before the development of the new techniques, for cloning and analysing DNA, that have revolutionized biological research during the past decade. Thousands of millions of dollars are now invested in industrial uses of these techniques, which all depend on discoveries made in the course of academic research on E. coli. Much of the background of knowledge necessary for the cloning and expression of genetically engineered information, as well as the techniques themselves, came from work with this organism.

Acute upper gastrointestinal bleeding (UGIB) is a common disorder and a gastroenterological emergency. With the development of new techniques and devices, the survivability after gastrointestinal bleeding is improving. However, at the same time, we are facing the difficulty of severely complicated cases with various diseases. For example, while endoscopic examination with a normal diameter endoscope is essential for the diagnosis and treatment of UGIB, there are several cases in which it cannot be used. In these cases, transnasal endoscopy (TNE) may be a viable treatment option. This report reviews current hemostatic devices for endoscopic treatment and the safety and efficiency of using TNE in complicated cases. The latter will be demonstrated in a case report where TNE was employed in a patient with severe esophageal stenosis. This review summarizes the advances made in the devices used and will provide further ideas for the physician in terms of combining these devices and TNE.

A 46- year-old woman presented a uterine adenosarcoma originating in the lower uterine segment. The diagnosis was made in an endometrial biopsy and confirmed in the pathological examination of the complete surgical specimen, both identifying heterologous malignant elements. In addition, complementary immunohistochemical studies were performed. We reviewed the literature, illustrating the clinical and morphological characteristics and the differential diagnoses to be evaluated.
