Prevalence of lymph nodes in the parametrium of radical vaginal trachelectomy (RVT) specimen
2011
Objective: In order to evaluate radicality in fertility preserving surgery in women with early invasive cervical cancer we analyzed the parametrium of specimens of patients treated by radical vaginal trachelectomy for the presence of lymph nodes. We tried to identify morphologic factors associated with the presence of parametrial lymph nodes. Methods: We analyzed surgical specimens of 112 patients who underwent radical trachelectomy between June 2004 and April 2009 at the Department of Gynecologic Oncology at Charité Campus Benjamin Franklin and Campus Mitte. All parametrial tissue was step sectioned and a total of 1878H&E stained histological sections were analyzed. Results: In 8 patients …
Values of broad band turbidity coefficients in a mediterranean coastal site
1999
Abstract The Angstrom turbidity coefficient, the Linke turbidity factor, and the Unsworth–Monteith coefficient have been determined and analysed based on measurements of normal direct irradiance and global horizontal irradiance taken in Valencia, Spain, between January 1990 and December 1996. The data, which were acquired automatically and continuously, have been filtered to select only those values corresponding to clear sky conditions. To determine the Angstrom turbidity coefficient the method proposed by Louche et al. has been used whilst the expression for δCDA proposed by Kasten was used to obtain the Linke turbidity coefficient. The Angstrom turbidity coefficient showed a minimum in w…
Quo plura possis, plura patienter feras. Agamennone modello di sapienza nelle Troiane di Seneca
2022
The paper deals with the quarrel between Pyrrhus and Agamemnon in the Troades, with an analysis of Greek and Latin antecedents, focusing in particular on the characterisation of the Achaean commander. The character of Agamemnon, who embodies the suffering of the defeated, shows a new model of royalty in line with Senecan ideology.
A Bio-Inspired Cognitive Agent for Autonomous Urban Vehicles Routing Optimization
2017
Autonomous urban vehicle prototypes are expected to be efficient even in not explicitly planned circumstances and dynamic environments. The development of autonomous vehicles for urban driving needs real-time information from vehicles and road network to optimize traffic flows. In traffic agent-based models, each vehicle is an agent, while the road network is the environment. Cognitive agents are able to reason on the perceived data, to evaluate the information obtained by reasoning, and to learn and respond, preserving their self-sufficiency, independency, self-determination, and self-reliance. In this paper, a bio-inspired cognitive agent for autonomous urban vehicles routing optimization…
RNA2-encoded VP37 protein of Broad bean wilt virus 1 is a determinant of pathogenicity, host susceptibility, and a suppressor of post-transcriptional…
2020
Abstract Broad bean wilt virus 1 (BBWV‐1, genus Fabavirus, family Secoviridae) is a bipartite, single‐stranded positive‐sense RNA virus infecting many horticultural and ornamental crops worldwide. RNA1 encodes proteins involved in viral replication whereas RNA2 encodes two coat proteins (the large and small coat proteins) and two putative movement proteins (MPs) of different sizes with overlapping C‐terminal regions. In this work, we determined the role played by the small putative BBWV‐1 MP (VP37) on virus pathogenicity, host specificity, and suppression of post‐transcriptional gene silencing (PTGS). We engineered a BBWV‐1 35S‐driven full‐length cDNA infectious clone corresponding to BBWV‐…
Annoyance due to residential road traffic and aircraft noise: Empirical evidence from two European cities
2021
Based on a study in two European cities, Mainz in Germany and Zurich in Switzerland, the article investigates both acoustical and non-acoustical factors affecting indoor annoyance due to residential road traffic and aircraft noise. We specifically focus on three factors: (1) the role of windows as a feature of the building where people live; (2) the role of individual environmental concern as a general attitude; and (3) the role of household income as an indicator of socioeconomic resources. Empirical results show that closed windows in general and closed high-quality windows in particular are an important barrier against outdoor road traffic and aircraft noise, as well as a helpful subject…
Perineural Invasion is a Strong Prognostic Moderator in Ampulla of Vater Carcinoma
2018
Objective Ampulla of Vater carcinoma (AVC) has a broad spectrum of different prognoses. As such, new moderators of survival are urgently needed. We aimed at clarifying the prognostic role of perineural invasion in AVC. Methods Using PubMed and SCOPUS databases, we conducted the first systematic review and meta-analysis on this topic. Results Analyzing 29 articles for a total of 2379 patients, we found that the presence of perineural invasion increased the risk of all-cause mortality more than 2 times (relative risk [RR], 2.07; 95% confidence interval [CI], 1.78-2.42 [P < 0.0001]; hazard ratio [HR], 2.72; 95% CI, 1.86-3.97 [P < 0.0001]), of cancer-specific mortality more than 6 times (…
Positron preferential annihilation in Bi-Sb alloys
2009
We report the measurements of the positron annihilation characteristics, i.e., positron lifetime and coincidence Doppler broadening spectra performed on five Bi-Sb alloys having a Bi content between 12.5 and 81 at.%. The strong effect of the preferential annihilation of positrons with the electrons of the Bi atoms has been revealed in these alloys.
Bioactive saponins from plants: An update
2000
Plant saponins are a group of naturally occuring triterpene or steroid glycosides which include a large number of biologically and pharmacologically active compounds. Saponins have been shown in both in vitroand in vivoexperimental test systems during the last decade to possess a broad spectrum of biological and pharmacological activities. This review will summarize some of the recent advances concerning cancer-related activity, immunostimulating, immunoadjuvant, antihepatotoxic, antiphlogistic, antiallergic, molluscicidal, hemolytic, antifungal, antiviral, and hypoglycemic activities. In addition, the effects on the cardiovascular system and the central nervous system will be discussed tog…
Medicinal Mushrooms: Bioactive Compounds, Use, and Clinical Trials
2021
Medicinal mushrooms have important health benefits and exhibit a broad spectrum of pharmacological activities, including antiallergic, antibacterial, antifungal, anti-inflammatory, antioxidative, antiviral, cytotoxic, immunomodulating, antidepressive, antihyperlipidemic, antidiabetic, digestive, hepatoprotective, neuroprotective, nephroprotective, osteoprotective, and hypotensive activities. The growing interest in mycotherapy requires a strong commitment from the scientific community to expand clinical trials and to propose supplements of safe origin and genetic purity. Bioactive compounds of selected medicinal mushrooms and their effects and mechanisms in in vitro and in vivo clinical stu…
