Only fermented flours showed the presence of protocatechuic acid compound. The solid-state fermentation was efficient to obtain extracts of granadilla seed flour enrichment of antioxidant bioactive compounds with potential of application in food, cosmetic and pharmaceutical industries.

Rapamycin is a clinically approved mammalian target of rapamycin inhibitor that has been shown to be neuroprotective in animal models of stroke. However, the mechanism of rapamycin-induced neuroprotection is still being explored. Our aims were to determine if rapamycin improved leptomeningeal collateral perfusion, to determine if this is through eNOS (endothelial nitric oxide synthase)-mediated vessel dilation and to determine if rapamycin increases immediate postreperfusion blood flow.

Wistar and spontaneously hypertensive rats (≈14 weeks old, n=22 and n=15, respectively) were subjected to ischemia by middle cerebral artery occlusion (90 and 120 minutes, respectively) with or without treatment with rapamycin at 30-minute poststroke. Changes in middle cerebral artery and collateral perfusion territories were measured by dual-site laser Doppler. Nedometinib molecular weight Reactivity to rapamycin was studied using isolated and pressurized leptomeningeal anastomoses. Brain injury was measured histologically or with triphenyltetrazoliuombectomy to improve reperfusion blood flow.

Rapamycin increased collateral perfusion and reperfusion cerebral blood flow in both Wistar and comorbid spontaneously hypertensive rats that appeared to be mediated by enhancing eNOS activation. These findings suggest that rapamycin may be an effective acute therapy for increasing collateral flow and as an adjunct therapy to thrombolysis or thrombectomy to improve reperfusion blood flow.

Brain atrophy can be regarded as an end-organ effect of cumulative cardiovascular risk factors. Accelerated brain atrophy is described following ischemic stroke, but it is not known whether atrophy rates vary over the poststroke period. Examining rates of brain atrophy allows the identification of potential therapeutic windows for interventions to prevent poststroke brain atrophy.

We charted total and regional brain volume and cortical thickness trajectories, comparing atrophy rates over 2 time periods in the first year after ischemic stroke within 3 months (early period) and between 3 and 12 months (later period). Patients with first-ever or recurrent ischemic stroke were recruited from 3 Melbourne hospitals at 1 of 2 poststroke time points within 6 weeks (baseline) or 3 months. Whole-brain 3T magnetic resonance imaging was performed at 3 time points baseline, 3 months, and 12 months. Eighty-six stroke participants completed testing at baseline; 125 at 3 months (76 baseline follow-up plus 49 delayed recrr the first year after stroke. Rapid brain volume loss in the first 3 months after stroke may represent a potential window for intervention. Registration URL https//www.clinicaltrials.gov. Unique identifier NCT02205424.

In December 2019, an outbreak of severe acute respiratory syndrome coronavirus causing coronavirus disease 2019 (COVID-19) occurred in China, and evolved into a worldwide pandemic. It remains unclear whether the history of cerebrovascular disease is associated with in-hospital death in patients with COVID-19.

We conducted a retrospective, multicenter cohort study at Mount Sinai Health System in New York City. Using our institutional data warehouse, we identified all adult patients who were admitted to the hospital between March 1, 2020 and May 1, 2020 and had a positive nasopharyngeal swab polymerase chain reaction test for severe acute respiratory syndrome coronavirus in the emergency department. Using our institutional electronic health record, we extracted clinical characteristics of the cohort, including age, sex, and comorbidities. Using multivariable logistic regression to control for medical comorbidities, we modeled the relationship between history of stroke and all-cause, in-hospital death.

We identified 3248 patients, of whom 387 (11.9%) had a history of stroke. Compared with patients without history of stroke, patients with a history of stroke were significantly older, and were significantly more likely to have a history of all medical comorbidities except for obesity, which was more prevalent in patients without a history of stroke. Compared with patients without history of stroke, patients with a history of stroke had higher in-hospital death rates during the study period (48.6% versus 31.7%,

<0.001). In the multivariable analysis, history of stroke (adjusted odds ratio, 1.28 [95% CI, 1.01-1.63]) was significantly associated with in-hospital death.

We found that history of stroke was associated with in-hospital death among hospitalized patients with COVID-19. Further studies should confirm these results.

Although it is recommended that elderly patients with non-ST-segment elevation myocardial infarction (NSTEMI) should undergo an assessment for invasive revascularization, these patients undergo fewer coronary interventions despite the current guidelines. The aim of the study is to evaluate the effectiveness of percutaneous coronary intervention on all-cause mortalities monthly and annually in the population.

Three hundred and twenty-four patients with NSTEMI aged 65 years or older who underwent coronary angiography and treated with conservative strategy or percutaneous coronary intervention were included in the study. All demographic and clinical characteristics of the patients were recorded and one-month and one-year follow-up results were analysed.

Two hundred eight cases (64.19%) were treated with percutaneous coronary intervention and 116 cases (35.81%) of the participant were treated with conservative methods. The mean age of the participants was 75.41 ± 6.65 years. The treatment strategy was an independent predictor for the mortality of one-year (HR 1.965). Furthermore, Killip class ≥2 (HR2.392), Left Ventricular Ejection Fraction (HR2.637) and renal failure (HR 3.471) were independent predictors for one-year mortality.

The present study has revealed that percutaneous coronary intervention was effective on one-year mortality in NSTEMI patients over the age of 65. It is considered that percutaneous coronary intervention would decrease mortality in these patients but it should be addressed in larger population studies.
