Consensus guidelines for the detection of immunogenic cell death

2014

Apoptotic cells have long been considered as intrinsically tolerogenic or unable to elicit immune responses specific for dead cell-associated antigens. However, multiple stimuli can trigger a functionally peculiar type of apoptotic demise that does not go unnoticed by the adaptive arm of the immune system, which we named "immunogenic cell death" (ICD). ICD is preceded or accompanied by the emission of a series of immunostimulatory damage-associated molecular patterns (DAMPs) in a precise spatiotemporal configuration. Several anticancer agents that have been successfully employed in the clinic for decades, including various chemotherapeutics and radiotherapy, can elicit ICD. Moreover, defect…

Recurrent intraoral HSV-1 infection : a retrospective study of 58 immunocompetent patients from Eastern Europe

2010

Objectives. To revise the clinical features of the recurrent intraoral herpetic infection (RIOH) with respect to precipitating factors, demographic, clinical features and outcome. Study design. Fifty-eight, unrelated Caucasian, immunocompetent patients with positive laboratory test for intraoral Herpes simplex virus infection were studied. Results. The mean age in the women?s group (n=42) was 41.23 years (± 21.73) and in the men?s group was 32.25 years (± 15.68). Possible trigger factors were identified in 9 cases (15.5%). General symptoms were noted in 20 cases (34.48%). Most of patients in this study presented multiple lesions. 14 patients had vermillion lesions associated with intraoral …

Three cases of neonatal herpes simplex virus infection presenting as fulminant hepatitis

1990

We report three cases of neonatal herpes simplex virus (HSV) infection presenting as fulminant hepatitis. None of the patients had clear risk factors for HSV infection and they all died. Antiviral treatment for HSV is currently available but must be administered early in the course of the disease before irreversible liver tissue damage is present. Since the diagnosis may be difficult to establish, we wish to draw the attention of clinicians to the presentation of neonatal HSV infection and suggest that in such cases viral cultures, including culture of liver tissue, should be obtained early and antiviral treatment administered while awaiting the culture results.

Traditional Chinese herbal medicine at the forefront battle against COVID-19: Clinical experience and scientific basis.

2020

Abstract Background Throughout the 5000-year history of China, more than 300 epidemics were recorded. Traditional Chinese herbal medicine (TCM) has been used effectively to combat each of these epidemics’ infections, and saved many lives. To date, there are hundreds of herbal TCM formulae developed for the purpose of prevention and treatment during epidemic infections. When COVID-19 ravaged the Wuhan district in China in early January 2020, without a deep understanding about the nature of COVID-19, patients admitted to the TCM Hospital in Wuhan were immediately treated with TCM and reported later with >90% efficacy. Approach We conducted conduct a systematic survey of various TCM herbal pre…

CYTOLOGY AND CLINICAL SPECTRUM OF SEXUALLY TRASMITTED INFECTIONS IN LEBANESE WOMEN ARE REVEALED BY PAP SMEAR: A CROSS-SELECTION STUDY FROM 2002-2006

2011

OBJECTIVE: To study the cytology profile of cervical smears and the respective prevalence and incidence of certain cervico-vaginal infections detectable by routine Pap smear cytology in Lebanese women from 2002 to 2006. METHODS: Pap smear cytology results were compiled from the archives of the “Institut National de Pathologie” for the period extending from 2002 until 2006. This study covered 118,230 cervical specimens obtained from Lebanese women attending clinics and hospitals in all the five districts of Lebanon; prevalence and incidence rates for infections detectable by routine Pap smear examination were determined. RESULTS: A rise in prevalence of these infections by 2.1% (2,555) from …

Prediction of banana quality indices from color features using support vector regression

2015

Banana undergoes significant quality indices and color transformations during shelf-life process, which in turn affect important chemical and physical characteristics for the organoleptic quality of banana. A computer vision system was implemented in order to evaluate color of banana in RGB, L*a*b* and HSV color spaces, and changes in color features of banana during shelf-life were employed for the quantitative prediction of quality indices. The radial basis function (RBF) was applied as the kernel function of support vector regression (SVR) and the color features, in different color spaces, were selected as the inputs of the model, being determined total soluble solids, pH, titratable acid…

Influence of double infections on the induction of thymidine kinase by UV-irradiated herpes simplex virus types 1 and 2 and pseudorabies virus

1975

Simultaneous infection of primary rabbit kidney cells with HSV type 1 TK+ and a TK- strain results in a mutual influence of both viruses on the induction of thymidine kinase (TK). TK+ virus has an enhancing and TK- virus a depressing effect on TK induction by a superinfecting TK+ virus. The enzyme induction depends on the ratio of multiplicities of both viruses. The mutual influence on TK induction depends further on the time of addition of the superinfecting virus: the effect of the second virus can still be observed when given 6 hours after primary infection. Identical phenomena can be observed using combinations with HSV type 2 or Pseudorabies viruses. The ability of HSV to induce TK is …

HSV-1 Glycoprotein D and Its Surface Receptors: Evaluation of Protein–Protein Interaction and Targeting by Triazole-Based Compounds through In Silico…

2023

Protein–protein interactions (PPI) represent attractive targets for drug design. Thus, aiming at a deeper insight into the HSV-1 envelope glycoprotein D (gD), protein–protein docking and dynamic simulations of gD-HVEM and gD-Nectin-1 complexes were performed. The most stable complexes and the pivotal key residues useful for gD to anchor human receptors were identified and used as starting points for a structure-based virtual screening on a library of both synthetic and designed 1,2,3-triazole-based compounds. Their binding properties versus gD interface with HVEM and Nectin-1 along with their structure-activity relationships (SARs) were evaluated. Four [1,2,3]triazolo[4,5-b]pyridines were i…
