Advanced treatment of urban wastewater by UV-C/free chlorine process: Micro-pollutants removal and effect of UV-C radiation on trihalomethanes formation.

The effect of the UV-C/free chlorine (FC) process on the removal of contaminants of emerging concern (CECs) from real urban wastewater as well as the effect of UV-C radiation on the formation of trihalomethanes (THMs) compared to FC process alone was investigated. Unlike of FC process, UV-C/FC was really effective in the degradation of the target CECs (carbamazepine (CBZ), diclofenac, sulfamethoxazole and imidacloprid) in real wastewater (87% degradation of total CECs within 60 min, Q = 1.33 kJ L), being CBZ the most refractory one (49.

Contaminants of emerging concern removal from real wastewater by UV/free chlorine process: A comparison with solar/free chlorine and UV/HO at pilot scale.

The removal of contaminants of emerging concern (CECs) from urban wastewater treatment plants (UWTPs) is really important to minimize the risk for human health and environment. In this study, the homogeneous advanced oxidation process (AOP) UV-C/free chlorine (UV-C/FC) was investigated at pilot scale in the degradation of a mixture of four CECs, in different water matrices and compared to a consolidated AOP, namely UV-C/HO. As matter of fact 90% degradation of CECs was observed after 15 min (Q = 0.

[Contribution of a combination of alpha and beta benzopyrones, flavonoids and natural terpenes in the treatment of lymphedema of the lower limbs at the 2d stage of the surgical classification].

Hypothesis: To create a phlebolymphologic therapy in order: to activate venous system; to activate lymphatic system; to activate macrophagic system; to reduce the proteic lymphatic load.

Experimental: A study was performed on the use of an ideal phlebolymphological association (Tonka Beans, Gingko Biloba, Melilotus Officinalis) as a practical standpoint in the treatment of lymphedema of lower limbs in order to create an efficacious dose of Coumarin, Benzopyrones and Ginkolidi. CLINICAL: We investigated a population of 76 patients treated in an open-label study for six-eight months with a dosage of Coumarin 60 mg/daily + Gingko Biloba 40 mg/daily + Melilotus 40 mg/daily.

["Simulated walking" in the duplex evaluation of the venous system. The clinical and instrumental correlations].

The goals of non-invasive duplex vascular diagnosis of the venous system of the lower limbs are: 1) To make evaluation of the venous system during deambulation feasible under physiological, pathological and post-surgical or elastocompressive conditions. Moreover, any such evaluation must be achieved using a standardized, easy, highly reproducibly method which is inexpensive and utilizes the diagnostic instruments available. 2) To achieve detailed, selective localization of the valvular and parietal dysfunctions at the basis of any reflux pathology.

[The implantation of a heterologous prosthesis in reparative abdominal-thoracic surgery. Experience with the use of clindamycin in preventing prosthesis-related infection].

The authors point out how infection of heterologous prosthesis, widely used in surgery, can be a dramatic event. On the other hand, antibiotic prophylaxis is difficult because of the difference between "in vitro" and "in vivo" activity of many antibiotics, due to the production, by many bacteria, of the so-called glycocalyx. This would allow bacteria to clump and adhere to many surfaces, forming micro-colonies, causing delay in phagocytosis, and reducing the efficacy of antibiotics.
