PURPOSE To better understand the efficacy and safety of anti-PD-1/PD-L1 therapy (atezolizumab, pembrolizumab, nivolumab) in patients with previously treated advanced non-small-cell lung cancer (NSCLC). METHODS The Cochrane Controlled Trial Register, Embase, Medline, and the Science Citation Index were searched for prospective published reports of atezolizumab, pembrolizumab, nivolumab in prev...

Depression is common and may occur at any stage in the long history of Parkinson’s disease, markedly affecting a patient’s threshold to discomfort, but it is particularly difficult to assess before clear clinical features are evident. The rate of depression in patients with Parkinson’s disease vary, partly because of differences in the definition of depression, difficulties in distinguishing be...

background: cognitive impairment in patients with parkinson’s disease (pd) mainly involves executive function (ef). the frontal assessment battery (fab) is an efficient tool for the assessment of efs. the aims of this study were to determine the validity and reliability of the psychometric properties of the persian version of fab and assess its correlation with formal measures of efs to provide...

Density functional theory has been used to investigate the thermodynamics and activation barriers associated with the direct oxidation of methane to acetic acid catalyzed by Pd2+ cation in concentrated sulfuric acid. Pd2+ cations in such solutions are ligated by two bisulfate anions and by one or two molecules of sulfuric acid. Methane oxidation is initiated by the addition of CH4 across one of...

Patterned 2-photon glutamate uncaging and local GABA iontophoresis were used to test, in brain slices, whether basal and oblique dendrites possess the biophysical machinery to contribute to the directional selectivity exhibited by many sensory neocortical neurons. On average, Distal-to-Proximal (DP) sequences of glutamate stimuli along individual dendrites produced ~1.5-fold larger responses th...

New chiral S,N- and S,P-ligands starting from tert-butanesulfinamide were synthesized in four steps, applying Pd-catalyzed asymmetric allylic substitutions of dimethyl 2-fluoromalonate. The induced effect of the Pd/S,N-ligand catalyst on the enantioselectivity depends on the steric demand of the substituent at the o-position of the pyridine ring. This method produced monofluorinated allylation ...

BACKGROUND Recent studies have suggested that melatonin-a hormone produced by the pineal gland under circadian control-contributes to PD-related sleep dysfunction. We hypothesized that degenerative changes to the neural structures controlling pineal function (especially the suprachiasmatic nuclei of the anterior hypothalamus) may be responsible for reduced melatonin output in these patients. We...

The role of PD-1 expression on CD4 T cells during HIV infection is not well understood. Here, we describe the differential expression of PD-1 in CD127high CD4 T cells within the early/intermediate differentiated (EI) (CD27highCD45RAlow) T cell population among uninfected and HIV-infected subjects, with higher expression associated with decreased viral replication (HIV-1 viral load). A significa...

parkinson’s disease (pd) is a prevalent neurodegenerative disease that usually affects individuals over 50 years of age. age at onset in a small subset of pd cases is considerably lower, and these are considered early-onset pd (eopd) patients. most pd cases appear sporadic, but approximately 15% are familial, and some of the familial cases exhibit mendelian inheritance. genetic analysis of fami...
