Infections of susceptible and resistant mouse strains with herpes simplex virus type 1 and 2.

1980

The spread of HSV of type 1 and 2 was investigated after intraperitoneal, intraplantar and intracerebral infections of resistant (C57/bl) and susceptible (NMRI) mice. The virus spreads after i.p. infection to the spleen and the liver to the same extent in both strains of mice. However, virus is eliminated earlier in resistant mice. Intracerebral infections revealed a peculiar type of resistance of C57/bl mice especially for type 2 of HSV. HSV multiplies in the thymus at the early stage of infection and can be detected in this organ in sick mice of NMRI strain. HSV-1 and 2 can be detected in the spinal cord of C57/bl mice without sickness or death of these animals.

Somatotypes and handgrip strength analysis of elite Serbian sambo athletes

2021

The aim of this study was to establish whether there are differences between weight categories in different anthropometric measurements and handgrip strength between elite Serbian male and female sambo athletes divided into weight categories. A total of 70 elite Serbian sambo athletes participated in the study, who were participants of the World Cadet Sambo Championship held in Novi Sad. Athletes are classified into categories according to gender and official weight categories. Using anthropometry, we calculated somatotypes and hand-grip strength. For statistical analysis, we used a one-way analysis of variance and Tukey’s post hoc tests to compare group differences by weight categories. So…

Analysis of gut microbiota in advanced non-small cell lung cancer (NSCLC) patients treated with immune-checkpoints blockers

2019

Abstract Background The microbiota community is considered as an organ of the human body. Recent studies have found that dysbiosis may have an impact on the interaction between immune regulation and tumor treatment. The main objective of this study is to characterize the gut microbiota in patients with non-small cell lung cancer (NSCLC) in advanced stages, and its relationship with obesity, smoking habits, clinical pathological features and response to treatment with immune-checkpoints blockers (ICB). Methods 16S rRNA gene sequencing was performed on 48 stool samples from advanced NSCLC patients prior to treatment with ICB (PD-1 inhibitor and PD-L1 inhibitor). The database used for the taxo…

Occupational exposure to pesticides and congenital malformations: A review of mechanisms, methods, and results

1998

Pesticides are chemicals that are widely used all over the world. Human beings can be exposed through environmental contamination and/or occupational use of pesticides. Although there is substantial information on the acute toxicity of many of these chemicals, available knowledge on delayed effects is much more limited. This paper reviews epidemiological studies on occupational exposure to pesticides, mainly in agricultural workers, and risk of congenital malformations. The discussion includes postulated mechanisms for birth defects from paternal or maternal exposure, a detailed review of method of the studies carried out so far on the relationship between occupational exposure to pesticide…

Tissue classification by texture and spectral analysis of intracoronary ultrasound radio-frequency data

2002

Imaging of vascular structures by intracoronary ultrasound allows in principal the recognition of different lesion types due to the echomorphology in the B-mode image. The subjective visual diagnosis is often difficult, especially the differentiation between thrombi and non-calcified plaque. The aim of this study was the extraction of features from the ultrasound radio-frequency signal for an objective characterization of coronary tissue. Methods of texture analysis and frequency analysis were used to differentiate red and white thrombi in vitro. Eight texture parameters of first and second order significantly differentiated red and white thrombi. The backscatter transfer function of red th…

Lasso Technique for Retrieval of a Dislocated and Impacted Esophageal Stent

2004

In vitro evaluation of forces exerted by a new computer-assisted colonoscope (the NeoGuide Endoscopy System).

2006

Background: The NeoGuide Endoscopy System (NES) utilizes a fully articulated, computer-controlled insertion tube that allows proximal segments of the colonoscope to follow the path taken by the tip as it is manually advanced through the colon. The system was designed to eliminate looping and scope displacement during colonoscopy. Material and methods: Using in vitro testing, an inanimate flexible model of the colon incorporating four force transducers located at the key flexure points was employed to measure the axial forces on the colon wall during colonoscopy. In the second part of the study, 10 gastroenterologists performed colonoscopies, using a training latex-based simulator, with the …

Oral squamous cell carcinoma mimicking osteonecrosis of the jaw: a case report

2021

Osteonecrosis of the jaw (ONJ) is a well-known adverse drug reaction to bisphosphonate (BP) treatment. ONJ diagnosis is usually based on the patient’s medical/medication histories and on the clinical/radiological features of necrotic bone (frequently exposed). Furthermore, in case of mandibular involvement, patients may present pain and/or hypesthesia of the inferior alveolar nerve. There are no pathognomonic clinical and radiological signs of ONJ, and in doubtful cases, the histologic examination is recommended. We report a case of a woman attending to our sector of Oral Medicine (AOUP “P. Giaccone” Palermo, Italy) with a mandibular bone exposure after implants loss and a medical history o…

Colonoscopy, Tumors, and Inflammatory Bowel Disease - New Diagnostic Methods

2006

Accurate detection of premalignant lesions and early cancers in the colon is essential for curative endoscopic or surgical therapy, since the prognosis for the affected patients is closely related to the size and stage of the neoplastic lesion. Total colonoscopy is the accepted gold standard for screening and surveillance of colorectal cancer. This review summarizes recently published diagnostic developments and key findings in the areas of colonoscopy, colonic tumors, and inflammatory bowel diseases. Relevant findings have been reported for chromo-endoscopy in the diagnosis of colitis-associated neoplasia, as well as flat and depressed adenomas. Real-time Doppler capabilities have now been…

Tips and tricks in office hysteroscopy

2015

Abstract Office hysteroscopy is a minimally invasive procedure that has been shown to be highly accurate in diagnosing abnormalities of the endometrial cavity and the endocervical canal. It allows the direct visualizing of uterine pathology without the need for general anesthesia and the use of an operating room, generating cost savings and greater compliance among patients. The advent of small-diameter hysteroscopes, the use of saline solution as a distension media, as well as the vaginoscopic technique have widely contributed to the diffusion of this technique worldwide, and currently it can be considered the gold standard for the examination of the uterine cavity. The improved technology…
