6% female; mean age, 46.3years; 52.9% with diabetic gastroparesis) were included. Treatment with velusetrag 30mg significantly increased the proportion of subjects with ≥20% reduction from baseline GE t

compared with placebo (52% vs 5%, P=0.002), and GE t

was numerically reduced following all three doses of velusetrag relative to placebo treatment. Efficacy was similar between subjects with diabetic and idiopathic gastroparesis. Velusetrag treatment was generally well tolerated; most TEAEs were mild and related to GI transit acceleration.

Velusetrag accelerates GE in subjects with diabetic or idiopathic gastroparesis and is generally well tolerated in this population (Clinicaltrials.gov NCT01718938).

Insight into the influence of each vinyl-conjugated electron-donating group on both vis-NIR absorption and fluorescence emission properties is provided. These trends are further corroborated by density functional theory computational analysis. Two of this series containing the 3,5-bis(vinyltriphenylamine) and 3,5-bis(vinylferrocenyl) substituents exhibit significant absorption cross sections in the biological transparency window justifying further investigation of their photoacoustic emission properties via both optical photoacoustic z-scan and photoacoustic tomography experiments. Both the 3,5-bis(vinyltriphenylamine) and 3,5-bis(vinylferrocenyl) substituted BODIPY dyes exhibit quantitative photoacoustic quantum yields. Relative to the commercially available methylene blue and indocyanine green molecular photoacoustic contrast agents, the 3,5-bis(vinyltriphenylamine)-derived BODIPY exhibits the greatest photoacoustic emission and contrast upon excited-state absorption at 685 nm excitation at a low power laser fluence ( less then 20 mJ cm-2 ).

This study aimed to assess associations between neutrophil-related primary immunodeficiencies (PIDs) and the presence of periodontal disease and other oral diseases and response to periodontal treatment.

Presence of neutrophil-related PIDs is thought to be a major risk factor for development of periodontitis.

This study had both a cross-sectional and cohort design. XCT790 Twenty-four children (age 4-16) with PIDs and 24 age-matched systemically healthy subjects received a dental clinical examination, including measures of probing pocket depths (PPD), clinical attachment loss (CAL) and bleeding on probing (BOP). Those found to be affected by periodontal disease were offered periodontal treatment and reassessed 6months later.

Diagnosis of PIDs was associated with increased odds of presence of periodontal disease (p=.008 adjusted for age, gender, plaque, OR=10.0, 95% CI=1.83-54.38) and with continuous measures of periodontal disease such as number of PPDs >4mm, mean PPD and mean CAL (all p<.001) and BOP (p=.001). However, only 7 out of 24 children were diagnosed with periodontitis. PIDs were also associated with a history of oral ulcers (p=.001, OR 12.47, 95% CI 2.71-57.29). An improvement in periodontal parameters (PPD and CAL) was detected following oral hygiene instructions and non-surgical periodontal therapy.

Although children affected by neutrophil-associated PIDs exhibited a higher prevalence of periodontal disease compared with systemically healthy children, severe periodontitis was rarely seen. This suggests that good systemic control of the PIDs may reduce their impact on the periodontium.

This study aimed to investigate the role of superoxide dismutase, an active molecule in the regulation of oxidative stress in the body, in the prevention of Treg apoptosis induced by specific Ags. Ag-specific Tregs were isolated from the DO11.10 mouse intestine. A food allergy mouse model was developed with ovalbumin as the specific Ag and here, we observed that exposure to specific Ag induced Treg apoptosis through converting the precursor of TGF-β to its mature form inside the Tregs. Oxidative stress was induced in Tregs upon exposure to specific Ags, in which Smad3 bound the latency-associated peptide to induce its degradation, converting the TGF-β precursor to its mature form, TGF-β. Suppressing oxidative stress in Tregs alleviated the specific Ag-induced Treg apoptosis in in vitro experiments and suppressed experimental food allergy by preventing the specific Ag-induced Treg apoptosis in the intestine. In conclusion, exposure to specific Ags induces Treg apoptosis and it can be prevented by upregulating superoxide dismutase or suppressing reactive oxidative species in Tregs.Polyamines are nitrogen-rich polycationic ubiquitous bioactive molecules with diverse evolutionary-conserved functions. Their activity interferes with numerous genes' expression resulting in cell proliferation and signaling modulation. The intracellular levels of polyamines are precisely controlled by an evolutionary-conserved machinery. Their transient synthesis is induced by heat stress, radiation, and other traumatic stimuli in a process termed the polyamine stress response (PSR). Notably, polyamine levels decline gradually with age; and external supplementation improves lifespan in model organisms. This corresponds to cytoprotective and reactive oxygen species scavenging properties of polyamines. Paradoxically, age-associated neurodegenerative disorders are characterized by upsurge in polyamines levels, indicating polyamine pleiotropic, adaptive, and pathogenic roles. Specifically, arginase overactivation and arginine brain deprivation have been shown to play an important role in Alzheimer's disease (AD) pathogenesis.
