Enhancing a Transition to a Circular Economy in the Water Sector: The EU Project WIDER UPTAKE
2021
A novel approach for resource recovery includes forward osmosis (FO) as a concentration step in municipal wastewater treatment. The current study investigates different pre-treatment strategies including biological treatment with a moving-bed bioreactor (MBBR) at different loading rates and particle removal by filtration and sedimentation. Membrane performance and recovery potential for energy and nutrients were investigated in laboratory-scale FO experiments in batch mode using pre-treated municipal wastewater as feed and 35 g/L NaCl as a draw solution. Initial water fluxes were in the range of 6.3 to 8.0 L/(m2·h). The baseline fluxes were modelled to account for flux decline due to concen…
Environmental Assessment of an Innovative High-Performance Experimental Agriculture Field
2022
To increase food availability, optimizing production systems and reducing burdens related to human activities is essential in a scenario of population growth and limited natural resources. In this context, the life cycle methodology can represent a valuable asset for assessing the environmental performance of agricultural products and services. This study sought to investigate and characterize potential impacts of an experimental tomato field at the University of Perugia and evaluate if the production increment obtained using high-reflective mulching compensated for the emissions caused by this extra component. The first-year crop campaign was the baseline reference to measure the system’s …
Design, Synthesis and Characterization of a Visible-Light-Sensitive Molecular Switch and Its PEGylation Towards a Self-Assembling Molecule.
2022
HBDI-like chromophores represent a novel set of biomimetic switches mimicking the fluorophore of the green fluorescent protein that are currently studied with the hope to expand the molecular switch/motor toolbox. However, until now members capable of absorbing visible light in their neutral (i. e. non-anionic) form have not been reported. In this contribution we report the preparation of an HBDI-like chromophore based on a 3-phenylbenzofulvene scaffold capable of absorbing blue light and photoisomerizing on the picosecond timescale. More specifically, we show that double-bond photoisomerization occurs in both the E-to-Z and Z-to-E directions and that these can be controlled by irradiating …
Bioactivity of Carlina acaulis essential oil and its main component to the olive fruit fly, Bactrocera oleae: ingestion toxicity, electrophysiologica…
2021
In recent years, botanical insecticides based on essential oils (EOs), or their main components, have received much attention as promising tools for Integrated Pest Management, due to their environmental safety and low side effects on non-target organisms. In this study, Carlina acaulis EO and its main component, carlina oxide, recently proven to be effective larvicidal and adulticidal agents against some insect pests, were analyzed for their toxicity, electroantennographic (EAG), and behavioral responses to adult olive fruit fly (Bactrocera oleae). The C. acaulis EO was more toxic to the tephritid than the carlina oxide, and both were more toxic to the same insect pest than EOs from other …
Development of choroidal neovascularization following transpupillary thermotherapy (TTT) for a small malignant melanoma of the choroid at the posteri…
2010
Abstract Introduction The malignant melanoma of the choroid is the most common primary malignant intraocular tumor in adults. There are currently several methods available for the treatment of choroidal melanomas. Among others, hyperthermia represents a therapeutic approach in which infrared radiation is delivered through the dilated pupil, called “transpupillary thermotherapy (TTT)”. The method was initially assumed to cause only a few side effects but gradually more and more complications have been observed. The treatment is associated with a number of vascular responses, for example arterial and venous occlusions. However neovascularizations of the choroid have only been detected twice s…
Subcutaneous Vulvar Flap Viability Evaluation With Near-Infrared Probe and Indocyanine Green for Vulvar Cancer Reconstructive Surgery: A Feasible Tec…
2021
Introduction: Vulvar cancer is a rare condition affecting older women and accounts for 3–5% of all gynecological cancers. Primary surgical treatment involves the removal of a large amount of tissue for which reconstructive surgery is often necessary with a high rate of postoperative complications. Despite several techniques for the evaluation of vulvar flap viability have been proposed, many methods cannot be performed during surgery and require expensive devices often missing in a gynecological clinic. This study aims to verify the feasibility and the safety of the vulvar flap viability evaluation through a near-infrared endoscopic probe and Indocyanine green (ICG) tracer in a small group …
Morphologische und funktionelle Ergebnisse nach transpupillarer Thermotherapie (TTT) maligner Aderhautmelanome
2006
BACKGROUND The aim of this study was to evaluate the course of tumor regression and visual impairment in choroidal melanomas treated by transpupillary thermotherapy (TTT) alone. PATIENTS AND METHODS In a prospective, non-randomized analysis 26 patients suffering from primary choroidal melanoma (posterior to the equator with base < or = 12 and thickness < or = 4.5 mm) were treated with the TTT standard protocol and followed for 33 - 45 months. Fluorescein and ICG angiographies were performed initially and after tumor regression clinically. RESULTS 22 tumors were significantly flattened after 1 - 3 TTT sessions. 4 tumors required additional therapy with ruthenium plaque. Visual acuity remaine…
Kinetik von Indozyaningrün (ICG) und adjuvanter Einsatz zur transpupillaren Thermotherapie (TTT) pigmentarmer kleiner Aderhautmelanome
2004
BACKGROUND To determine the efficacy of intravenous indocyanine green (ICG) as an adjuvant to TTT for hypopigmented choroidal melanomas. PATIENTS AND METHODS ICG kinetics in melanoma tissue were evaluated by taking standardized ICG angiograms in 28 eyes with small choroidal melanomas. In a prospective non-randomized analysis 12 eyes with hypopigmented choroidal melanomas (posterior to the equator with thickness </= 4.5 mm) were treated with the TTT standard protocol developed by an intravenous injection of 100 mg ICG in 10 ml aqueous solvent 2 minutes after starting TTT. These eyes were followed-up for at least 22 months (mean 29). RESULTS Pharmacokinetic analyses revealed the onset of fluo…
EP1155 Endoscopic near infrared and indocyanine green to verify the viability of the subcutaneous flap for vulvar cancer
2019
Introduction/Background Vulvar cancer often requires radical vulvectomy with subsequent vulvar flap due to tumor aggressiveness and a high percentage of relapses. Approximately in 20–60% of cases, there are post-operative complications ranging from infection to wound dehiscence, lymphocele and flap necrosis that often require reoperation. Several methods have been described to verify the vitality of the flap, especially in plastic surgery, but these are often expensive and require specific machinery that is not generally present in a gynecological clinic. We present a viability verification of V-Y fasciocutaneous advancement flap for vulvar reconstruction by Endoscopic Near-Infrared and Ind…
EP626 Lymph vascular space invasion, an independent risk factor of sentinel node mapping failure in endometrial cancer, the sentifail study: a multic…
2019
Introduction/Background Sentinel lymph node (SLN) mapping has become the gold standard for surgical staging of early stage endometrial cancer. Side-specific systematic lymphadenectomy is suggested if SLN mapping failed. The objective of this study is to identify clinical and pathological factors associated with failed mapping. Methodology We prospectively evaluated a consecutive series of early stage endometrial cancer patients submitted to SLN mapping with indocyanine green (ICG) near-infrared compatible surgical platforms in two oncological referral centers from January 2018 to January 2019. Indocyanine green was injected intracervical. Bilateral mapping and failed bilateral SLN mapping g…
