Localization and classification of space objects using EfficientDet detector for space situational awareness.

Space situational awareness (SSA) systems play a significant role in space navigation missions. One of the most essential tasks of this system is to recognize space objects such as spacecrafts and debris for various purposes including active debris removal, on-orbit servicing, and satellite formation. The complexity of object recognition in space is due to several sensing conditions, including the variety of object sizes with high contrast, low signal-to-noise ratio, noisy backgrounds, and several orbital scenarios.

Minimally Invasive Pilonidal Excision: Preliminary Report.

Background: The aim of this study was to report on the application of a minimally invasive technique to the radical extirpation of primary and recurrent pilonidal disease. This technique does not require specific equipments, is ordinarily performed under local anesthesia on an outpatient basis, and provides optimal cosmetic results.

Methods: A total of 187 patients including 68% of patients with previous pilonidal surgery and 12% cases of extensive disease underwent surgery as day case.

Minimally invasive surgery for the treatment of pilonidal disease. The Gips procedure on 2347 patients.

Background: Pilonidal disease is a quite common chronic inflammatory disease that causes discomfort, embarrassment and absence from work or school. In line with its acquired pathogenesis, a number of surgical alternatives to conventional en bloc excision have been proposed over the last decades, yielding encouraging results. We reviewed our experience with minimally invasive sinusectomy to evaluate its safety and efficacy.

A 15-year experience of two hundred and twenty five consecutive right hepatectomies.

Background: In case of liver tumor, surgical resection is the therapeutic gold standard to increase patient survival. Among liver resections, right hepatectomy (RH) is defined as a major hepatectomy. The first aim of this study was to analyze the overall morbidity and mortality of patients undergoing RH, the second aim was to assess changes in both patients characteristic and surgical parameters and mortality rates in a single center institution.

Obesity-independent association of human adenovirus Ad37 seropositivity with nonalcoholic fatty liver disease.

Objective: Adenoviruses Ad36 and Ad37 increase adiposity in animals and are associated with obesity in humans; effects on the liver have been reported. The association of Adenovirus Ad36 seropositivity (Ad36+) with obesity but not with the severity of nonalcoholic fatty liver disease (NAFLD) has been previously shown. We investigate whether nondiabetic Ad37+ patients show a different prevalence of NAFLD and ultrasound Bright Liver score.

Adenovirus-36 seropositivity enhances effects of nutritional intervention on obesity, bright liver, and insulin resistance.

Background: Obesity and liver steatosis are both currently attributed to inappropriate lifestyle and nutrition. Higher prevalence of human adenovirus Ad36 seropositivity (Ad36+) is reported only in obesity.

Aims: To investigate whether a lifestyle-nutritional intervention achieves different outcomes in NAFLD patients, i.

Video-assisted versus open ileocolic resection in primary Crohn's disease: a comparative case-matched study.

Despite the technical difficulties, laparoscopic ileocolic resection for Crohn's disease (CD) has become widely accepted in recent years, due to its potential benefits. There are numerous reports concerning the use of laparoscopy in successfully treating CD, including two randomized trials and few comparative studies. For the most part, these reports outline use of laparoscopic approach in primary distal ileal or ileocolic disease, with a careful selection of the patients.

[Role of anastomotic configuration in ileocolic resection for Crohn's disease].

Crohn's disease is characterised by a high incidence of perianastomotic recurrence after ileocolic resection. The influence of the anastomotic configuration on the incidence of reoperation was evaluated in patients undergoing resection for Crohn's disease. In our Institution, from 1993 to 2007, 308 consecutive patients affected by ileocolic Crohn's disease were submitted to 343 ileocolic resections or right colectomies.

Isothiazole derivatives as antiviral agents.

We recently described the synthesis and antiviral activity of the compounds 5-phenyl-3-(4-cyano-5-phenylisothiazol-3-yl) disulphanyl-4-isothiazolecarbonitrile and S-(4-cyano-5-phenylisothiazol -3-yl)-O-ethyl thiocarbonate, which were found to be effective against both HIV-1 (IIIB) and HIV-2 (ROD). We have now evaluated these compounds against both RNA and DNA viruses, obtaining high selectivity indexes for poliovirus 1 (SI: 223 and 828, respectively) and Echovirus 9 (SI: 334 and 200, respectively). In our previous studies, 3-methylthio-5-(4-OBn-phenyl)-4-isothiazolecarbonitrile was found to exhibit a broad spectrum of action against picornaviruses, we therefore selected this compound and S-(4-cyano-5-phenylisothiazol-3-yl)-O-ethyl thiocarbonate as the model for the synthesis of a new isothiazole derivative, S-[4-cyano-5-(4-OBn-phenyl)isothiazol-3-yl]-O-ethyl thiocarbonate.

[Perforated jejunal diverticulum: a rare cause of acute abdomen].

Jejunal diverticulum is an uncommon, acquired condition, and the majority of patients are usually asymptomatic. Jejunal diverticula become clinically relevant when complications, such as diverticulitis, intestinal bleeding, obstruction, or perforation occur. A rare case of acute abdomen due to a perforated jejunal diverticulum is presented.

Isothiazole derivatives as novel HIV replication inhibitors.

A series of 3,4,5-trisubstituted isothiazoles has been screened against HIV-1 (IIIB) and HIV-2 (ROD) at sub-toxic concentrations in acutely infected MT-4 cells. Among the tested compounds, only 3-mercapto-5-phenyl-4-isothiazolecarbonitrile was found to inhibit the replication of HIV-1 (IIIB) and HIV-2 (ROD) at 50% effective concentrations (EC50) of 7.8 and 9.
