The high acquisition of drug resistance by Mycobacterium tuberculosis necessitates the ongoing search for new drugs to be incorporated in the tuberculosis (TB) regimen. Compounds used for the treatment of other diseases have the potential to be repurposed for the treatment of TB. In this study, a high throughput screening of compounds against thiol-deficient M. smegmatis strains and subsequent validations with thiol-deficient M. tuberculosis strains, revealed that Δ egtA and Δ mshA mutants had increased susceptibility to azaguanine (Aza) and sulfaguanidine (Su), Δ egtB and Δ egtE mutants had increased susceptibility to bacitracin (Ba) and Δ egtA , Δ mshA , and Δ egtB mutants had increased susceptibility to fusaric acid (Fu)...

The stress response of permanently crosslinked gelatin gels was recently observed to display glass-like features, namely, a stretched-exponential behavior terminated by an exponential decay, the characteristic time scales of which increase dramatically with decreasing temperature. This phenomenon is studied here using a model of flexible polymer gel network where relaxation proceeds via elementary monomer exchanges between helix and coil segments. The relaxation dynamics of a full network simulation is found to be nearly identical to that of a model of independent strands, which shows that for flexible polymer gels in the range of elastic moduli of interest, both strand contour length disorder and elastic couplings are irrelevant...

The walls and mural paintings of Pompeii exposed directly to the rainfalls are the most impacted in view of the observed decay. However, there are also wall paintings in protected rooms showing evidences of decaying. The aim of this research was to study the salts formed in such protected wall paintings only by non-invasive and in-situ Raman spectroscopy to understand their decaying processes. The perystile of the House of the Gilded Cupids (Regio VI, Insula 16), one of the most important houses of Pompeii was studied...

Surgical treatment of elderly patients with meningioma is has proved to be safe, especially when patients are selected using dedicated surgical scores. These scores take into account tumor size, edema, location and patient's co-morbidities. Neuropsychological functioning (NPF) of this kind of patients has been poorly studied in literature and it is not taken into account by these scores. Aim of our study was to describe the long-term outcome in terms of NPF of elderly patients undergoing surgery. Patients older than 70 years of age affected by intracranial meningioma and selected with the Clinical-Radiological Grading Score were included in our study...

CONTEXT: Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible...

RATIONALE: Spinal cord stimulation (SCS) is an effective option for neuropathic pain treatment. New technological developments, as high-frequency (HF) and theta burst stimulation (TBS), have shown promising results, although putative mechanisms of action still remain debated. METHODS: thirty patients with lower back pain were enrolled and underwent LF, HF, and TBS. Laser evoked potentials (LEPs) were recorded by using a Nd:YAG laser. Amplitudes and latencies of the main two components (N1, N2/P2) were compared among different experimental sessions...

A simple protocol is described for locating the site of action of an antioxidant (AO) in a micro-heterogeneous mixture, based on the pattern of the reactivity curve towards the AO of a series of 4-alkanoyl TEMPO radicals. The resulting cut-off curves yield information regarding the hydrophobic microenvironment surrounding the reactive AO group, and its accessibility by the probe. Convex curves are an indication of an AO located in a more hydrophilic environment, while concave plots originate from AOs in a more hydrophobic location in the micro-heterogeneous system...

The copper oxides present the highest superconducting temperature and properties at odds with other compounds, suggestive of a fundamentally different superconductivity. In particular, the Abrikosov vortices fail to exhibit localized states expected and observed in all clean superconductors. We have explored the possibility that the elusive vortex-core signatures are actually present but weak. Combining local tunneling measurements with large-scale theoretical modeling, we positively identify the vortex states in YBa_{2}Cu_{3}O_{7-δ}...

AIM: Inadequate sun exposure impairs Vitamin D activity and favors low bone density, more so in patients at increased risk for osteoporosis, as those affected by Inflammatory Bowel Disease. Sun exposure (SE) was investigated in a large series of IBD patients in a Mediterranean Country, Italy, where this risk is considered less likely to occur compared to those from higher latitudes. METHODS: Case-control study in 292 IBD patients (132 Crohn's Disease and 160 Ulcerative Colitis), 80 diseased and 540 healthy controls, administering a validated questionnaire to quantify SE...

Major surgeries can result in high rates of adverse postoperative events. Reliable prediction of which patient might be at risk for such events may help guide peri- and postoperative care. We show how archiving and mining of intraoperative hemodynamic data in orthotopic liver transplantation (OLT) can aid in the prediction of postoperative 180-day mortality and acute renal failure (ARF), improving upon predictions that rely on preoperative information only. From 101 patient records, we extracted 15 preoperative features from clinical records and 41 features from intraoperative hemodynamic signals...

This study reviewed the link between social media and the growing epidemic of childhood obesity in Europe. A task force from the European Academy of Paediatrics and the European Childhood Obesity Group searched published literature and developed a consensus statement. It found that there was evidence of a strong link between obesity levels across European countries and childhood media exposure and that parents and society needed a better understanding of the influence of social media on dietary habits. CONCLUSION: Health policies in Europe must take account of the range of social media influences that promote the development of childhood obesity...

Caroli's disease is a very rare congenital malformation, currently included in cystic diseases of the biliary tract, and is characterized by ectasia and dilatation of the intrahepatic bile ducts. Two clinical entities can be distinguished, Caroli's disease in which congenital hepatic impairment is limited to cystic dilatation and Caroli's syndrome in which congenital hepatic fibrosis coexists. We present two cases of atypical presentations of Caroli's disease. Case one was a 76-year-old man who was referred to our hospital for chronic non-remitting epigastric pain prior to diagnosis...

The present study investigated: (a) the presence of antiphospholipid antibodies and (b) the obstetric outcome in healthy pregnant women showing false-positive TORCH-Toxoplasmosis, Other: syphilis, varicella-zoster, Rubella, Cytomegalovirus (CMV), and Herpes infections-results. Data from 23 singleton healthy pregnancies with false-positive TORCH results were collected. Each woman was systematically screened for TORCH IgG and IgM during the pre-conception assessment and/or at the beginning of pregnancy. In the presence of IgM positivity, when indicated (CMV, toxoplasmosis, rubella, herpes simplex virus), IgG avidity was evaluated and, if possible, polymerase chain reaction was performed on an amniotic fluid sample in order to distinguish between primary infection or false positivity...

The association between choline uptake and androgen receptor (AR) expression is suggested by the upregulation of choline kinase-alpha in prostate cancer. Recently, detection of AR aberration in cell-free DNA as well as early 18F-fluorocholine positron emission tomography/computed tomography (FCH-PET/CT) were associated with outcome in metastatic castration-resistant prostate cancer (mCRPC) patients treated with abiraterone and enzalutamide. We aimed to make a direct comparison between circulating AR copy number (CN) and choline uptake at FCH-PET/CT...

OBJECTIVES: Biofilm formation (BF) by fungal isolates may dramatically complicate infection. We determined the ability of C. parapsilosis isolates from single fungaemia episodes to form biofilms and we analysed biofilm subgroups for antifungal susceptibility and pathogenic potential. We then correlated BF with clinical characteristics and outcomes of the episodes. METHODS: BF was measured using the crystal-violet biomass assay, antifungal susceptibility of preformed biofilms was assessed, and virulence was studied using the Galleria mellonella model...

PURPOSE: The role of 18F-choline positron emission tomography/computed tomography (FCH-PET/CT) in patients with metastatic castration-resistant prostate cancer (mCRPC) has been firmly established in recent years. We analyzed the prognostic value of functional parameters such as mean standardized uptake volume (SUVmean), maximum standardized uptake volume (SUVmax), metabolic total volume (MTV; the volume of interest consisting of all spatially connected voxels within a fixed threshold of 40% of the SUVmax), and total lesion activity (TLA: the product of MTV and mean standardized uptake value) estimated with FCH-PET/CT in mCRPC patients in progression after docetaxel and treated with new antiandrogen receptor therapies, abiraterone or enzalutamide...

Chronic infection with the hepatitis C virus induces liver fibrosis, but it is unknown why some patients progress to advanced fibrosis while others remain with mild disease. Recently, an inverse association between serum levels of dehydroepiandrosterone sulphate (DHEA-S) and liver fibrosis in patients with nonalcoholic fatty liver disease was described and it was postulated that dehydroepiandrosterone (DHEA) has anti-fibrotic effects. Our aim was to compare serum DHEA-S levels with liver fibrosis in hepatitis C patients...
