By taking advantage of naturally stable Envs, gp41ECTO swapping may represent a universal approach for the generation of stable trimers with the desired structural and antigenic properties for downstream in vivo evaluation and vaccine development.Aim Human Leukocyte Antigen-G (HLA-G) is a non-classical class I molecule that is involved in maternal-fetal immunotolerance. In cancer, this molecule contributes to the tumor escape. The aim of this study was to evaluate the 14 bp In/Del and +3142 C > G polymorphisms of the HLA-G 3' UTR and its relation with plasma and tissue HLA-G expression in patients with grade IV (high-grade) and grade I/II (low-grade) gliomas and controls.Patients and methods Peripheral blood and tumor biopsies were collected from 85 patients with gliomas and blood samples from 94 controls. Polymorphisms were analyzed from blood DNA. Soluble HLA-G (sHLA-G) was measured by ELISA in plasma of the subjects and the tissue expression by immunohistochemistry on patient's tissue.Results Higher levels of sHLA-G were observed in grade IV gliomas patients than in controls (p  less then  0.0001). In grade IV patients, the heterozygous 14pb In/Del, +3142 C/G genotypes and Del/C*In/G haplotype were associated with higher sHLA-G levels (p  less then  0.0001) when compared with controls. GBM patients were stratified into high and low sHLA-G expression and an association was found between +3142 C allele and high sHLA-G plasmatic levels (p = 0.0095). Tissue HLA-G immunolabel was higher in high-grade than low-grade gliomas (p = 0.0033).Conclusion This was the first study evaluating HLA-G 3' UTR polymorphisms and expression in patients with gliomas. The 14 bp In/Del and +3142 C/G genotypes and haplotypes showed high influence over sHLA-G expression, suggesting a heterozygous advantage in the tumor context and may contribute to a worse prognosis in glioma patients.Microtubules (MTs) play an essential role in mitosis; hence they are identified as potential targets to design novel anti-mitotic agents. MT's are composed of α/β-tubulin isotypes that are associated with differential drug-resistant effects against MT-targeting agents. Peloruside-A (PLA) is a potent anti-mitotic agent showing excellent activity against taxol-resistant carcinoma. PLA alters MT dynamics by binding to the 'non-taxoid' site of β-tubulin. The abundance of βII and βIII tubulin isotypes in human ovarian carcinoma affects the efficacy of PLA. Nevertheless, the mechanism of PLA resistance due to βII and βIII tubulin isotype is not well understood. Therefore, we investigated the interactions of PLA with αβIIa, αβIIb, and αβIII tubulin isotypes which are predominantly expressed in the human ovarian carcinoma, using a molecular modeling approach. A sequence analysis study shows that the βIII isotype has seven residue variations at the 'non-taxoid' site compared to the βIIa and βIIb isotypes. Molecular docking and molecular dynamics simulation revealed that residue variation at the 'non-taxoid' site of βIII isotype affect PLA binding. Furthermore, binding energy calculations showed that αβIIa has the highest binding towards PLA, whereas αβIIb and αβIII isotypes shows weaker associations with PLA. Our computational study provides valuable structural and energetic information to increase understanding into the origin of PLA resistance in human ovarian carcinoma and could be helpful to develop potential PLA analogs against specific β-tubulin isotypes expressed in cancer cells.Communicated by Ramaswamy H. Sarma.Background Rhythmic masticatory muscle activity (RMMA) in sleep is usually not considered pathological unless associated with bruxism. On the other hand, so-called sleep-related rhythmic movement disorders (SRRMD) are a recognized category of sleep disorders, which involve prolonged rhythmic activity of large muscle groups, such as the whole body, the head, or a limb, but typically not the masticatory muscles.Clinical Presentation A polysomnographic description of a patient with symptomatic RMMA without bruxism, fulfilling the diagnostic criteria of an SRRMD, is presented. The symptoms were initially misdiagnosed as bruxism and then as sleep-related epilepsy, which delayed an adequate treatment. Therapy of the comorbid obstructive sleep apnea with a positive airway pressure device (APAP) led to a self-reported improvement.Conclusion The differential diagnosis of jaw movement in sleep is vast; a correct diagnosis is of the essence for adequate treatment. The prevalence of isolated RMMA resulting in perturbation of sleep warrants further exploration.Aim of the Study Cardioembolic stroke accounts for approximately 15-25% of ischemic strokes and is characterized by a poor prognosis. Atrial fibrillation (AF) is more commonly diagnosed in the elderly.The aim of the study was the assessment of the manifestations of AF in patients hospitalized due to cerebral stroke, with particular attention paid to newly diagnosed AF.Methods A retrospective analysis was performed on 998 cerebral stroke patients. The data were analyzed for sex, age, cerebral stroke risk factors, drugs, NIHSS, RANKIN scores and ECG recordings on admission and at discharge.Results The mean age of disease onset was 73 ± 16 years. Women accounted for 50.8% of patients. read more AF prior to hospital admission was diagnosed in 20.1% of patients, while de novo AF in 26.3% of patients during hospitalization. Hypercholesterolemia, hypertriglyceridemia and smoking were more commonly reported in ischemic stroke patients without AF compared to patients with ischemic stroke and AF. Ischemic heart disease, more frequent deaths, and a worse prognosis were more frequently observed in patients with ischemic stroke and AF compared to patients without AF. The first manifestation of AF in 25% of stroke patients was related to the period of the first 10 days of hospitalization.Discussion The above data should prompt neurologists, cardiologists and family doctors to try to detect AF as a risk factor for ischemic stroke which worsens patient prognosis, prolongs hospital stay and contributes to increase in mortality, especially when more effective drug treatment is currently possible.
