BACKGROUND: Inhibitory receptor programmed cell death protein-1 (PD-1) is upregulated on a variety of immune cells, including natural killer (NK) cells, during chronic virus infection and tumorigenesis. Blockade of PD-1 or its ligands produces durable clinical responses with tolerable side effects in patients with a broad spectrum of cancers. However, the underlying molecular mechanisms of how PD-1 regulates NK cell function remain poorly characterized. OBJECTIVE: We sought to determine what effect PD-1 signaling has on NK cells...

BACKGROUND: Precision medicine and prediction of therapeutic response requires monitoring potential biomarkers before and after treatment. Liquid biopsies provide noninvasive prognostic markers such as circulating tumor DNA and RNA. Circulating tumor RNA (ctRNA) in blood is also used to identify mutations in genes of interest, but additionally, provides information about relative expression levels of important genes. In this study, we analyzed PD-L1 expression in ctRNA isolated from various cancer types...

AIMS: The accumulation of α-synuclein is a hallmark in the pathogenesis of Parkinson's disease (PD). Natural resistance-associated macrophage protein-1 (Nramp1) was previously shown to contribute to the degradation of extracellular α-synuclein in microglia under conditions of iron overload. This study was aimed at investigating the role of Nramp1 in α-synuclein pathology in the neuron under MPTP/MPP+ treatment. METHODS: The expression of Nramp1 and pathological features (including iron and α-synuclein accumulation) were examined in the dopaminergic neurons of humans (with and without PD) and of mice (with and without receiving chronic 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intoxication)...

OBJECTIVES: Falls are a common problem in older people. Postural hypotension contributes to falls but is often asymptomatic. In the absence of symptoms, postural hypotension is only infrequently checked for in clinical practice. We undertook this study to derive, validate and explore the prospective associations of a prediction tool to identify people likely to have unrecognised postural hypotension. DESIGN AND SETTING: Cross-sectional and prospective multivariable cohort analysis...

We have elaborated a two-step catalytic approach to nafoxidine, a key precursor to lasofoxifene. Firstly, an efficient α-arylation of 6-methoxy-3,4-dihydronaphthalen-1(2H)-one with chlorobenzene was developed, which operates at low 0.1 mol% Pd-132 catalyst loading in the presence of 1.9 equivalents of sodium tert-butoxide at 60 °C in 1,4-dioxane and provides 6-methoxy-2-phenyl-3,4-dihydronaphthalen-1(2H)-one in 90% yield. Secondly, we have demonstrated that 6-methoxy-2-phenyl-3,4-dihydronaphthalen-1(2H)-one can be converted to nafoxidine in 61% yield via CeCl3 promoted reaction with (4-(2-(pyrrolidin-1-yl)ethoxy)phenyl)lithium, which is formed in-situ from the corresponding arylbromide precursor and n-butyllithium...

Neuroinflammation is a common pathogenic mechanism for a number of neurodegenerative disorders including Alzheimer's and Parkinson's diseases. Microglia, the immune cells of the brain, contribute to the onset and progression of the neuroinflammation observed in these diseases. Microglia become activated and initiate an inflammatory response by interacting with a diverse set of molecules, including the group of endogenous proteins released upon cell damage, termed damage-associated molecular patterns (DAMPs)...

The development of immune checkpoint inhibitors (monoclonal antibodies targeting PD-1/PD-L1 or CTLA-4) represents a significant advance in the treatment of multiple cancers. Given their particular mechanism of action, which involves triggering CD4+/CD8+ T-cell activation and proliferation, they are associated with a specific safety profile. Their adverse events are primarily immune-related, and can affect practically all organs. In this context, dermatological toxicity is the most common, though it mostly remains mild to moderate and does not require discontinuation of treatment...

We investigate what supervised classification models using clinical and wearables data are best suited to address two important questions about the management of Parkinson's Disease (PD) patients: 1) does a PD patient require pharmacotherapy or not, and 2) whether therapies are having an effect. Currently, patient management is suboptimal due to using subjective patient reported episodes to answer these questions. METHODOLOGY: Clinical and real environment sensor data (memory, tapping, walking) was provided by the mPower study (6805 participants)...

Sang Moon Lee, Sung Chang Hong, Sung Su Kim
A Pd/Ni-YSZ porous membrane with different palladium loadings and hydrazine as a reducing reagent was prepared by electroless plating and evaluated for the steam methane reforming activity. The steam-reforming activity of a Ni-YSZ porous membrane was greatly increased by the deposition of 4 g/L palladium in the low-temperature range (600 °C). With an increasing amount of reducing reagent, the Pd clusters were well dispersed on the Ni-YSZ surface and were uniform in size (∼500 nm). The Pd/Ni-YSZ catalytic porous membrane prepared by 1 of Pd/hydrazine ratio possessed an abundant amount of metallic Pd...

Fimasartan is the ninth and latest Angiotensin Receptor Blockers for the treatment of hypertension. Fimasartan is a derivative of losartan in which the imidazole ring has been replaced, a change that provided higher potency and longer duration than losartan. It provides a selective type 1 angiotensin II receptor antagonist effect with noncompetitive, insurmountable binding. Fimasartan is rapidly absorbed following oral administration with an oral bioavailability of 18.6 ± 7.2 %. Fimasartan is relatively stable in terms of metabolism and more than 90 % of circulating fimasartan moieties in the plasma are in the parent form; fecal elimination and biliary excretion are the predominant elimination pathways of fimasartan...

B cell interaction with follicular helper T cells and their subsequent differentiation into high-affinity antibody producing cells normally takes place in secondary lymphoid organs. The costimulator ICOS plays a key role in this process and is therefore considered as an attractive target to modulate exaggerated B cell responses in autoimmune or allergic diseases. Inflamed tissues were recently recognized as additional sites of active T cell/B cell interaction. To analyze whether ICOS costimulation is also important there, we employed a mouse airway inflammation model which allows to directly compare immune reactions in the lung-draining lymph node and the lung tissue and also to assess the relative importance of dendritic cells versus B cells as antigen-presenting cells...
