Enzyme-assisted aqueous extraction combined with experimental designs allows the obtaining of a high-quality and yield pecan nut oil
In this study, pecan nut oil was obtained by EAE and mechanical pressing (MP), and its physicochemical properties and chemical composition were compared. The extraction conditions were selected applying the enzymes Alcalase® and/or Celluclast® used either singly or in combination. After using the Plackett-Burman design followed by a Central Composite Rotatable Design, the highest extraction yield (65.3%) was obtained using Alcalase® (1.50 g/100 g) after 4 h, in pH 8.00, at 52 °C, and substrate concentration of 0.40 g/mL. The peroxide values (1.99 and 1.90 mEq O2/kg of oil obtained by EAE and MP, respectivel...

Corbicula fluminea rapidly accumulate pharmaceuticals from an effluent dependent urban stream.
Abstract
Freshwater bivalve populations are stressed by watershed development at the global scale. Though pharmaceuticals released from wastewater treatment plant effluent discharges are increasingly reported to bioaccumulate in fish, an understanding of bioaccumulation in bivalves is less defined. In the present study, we examined accumulation of 12 target pharmaceuticals in C. fluminea during a 42 day in situ study in Pecan Creek, an effluent dependent wadeable stream in north central Texas, USA. Caged clams were placed at increasing distances (5 m, 643 m, 1762 m) downstream from a municipal efflu...

Independent and incremental value of Ventilation/Perfusion PET/CT and CT pulmonary angiography for pulmonary embolism diagnosis: results of the PECAN pilot study
Conclusions: In this pilot study, we have demonstrated the feasibility and potential utility of V/Q PET/CT for the management of patients with suspected acute PE. V/Q PET/CT may be of particular relevance in cases of equivocal findings or isolated subsegmental findings on CTPA, adding further discriminatory information to allow important decision-making regarding application or withholding of treatment courses of therapeutic anticoagulation, which may confer an increased risk of bleeding. Given the other advantages of V/Q PET/CT (reduced acquisition time, low radiation dose), and with increasing availability of 68Ga-genera...

Cellular Evaluation of the Antioxidant Activity of U.S. Pecans [Carya illinoinensis (Wangenh.) K. Koch]
This study examined antioxidant efficacy of U.S. pecans using a modified cellular antioxidant activity (CAA) assay with comparisons to data from in vitro antioxidant assays (hydrophilic-oxygen radical absorbance capacity {H-ORACFL} and ferric reducing antioxidant power {FRAP}). Crude phenolic extracts from both raw and roasted pecans were analyzed. In the CAA assay, pecan phenolics were taken up by human colorectal adenocarcinoma (Caco-2) cells and bestowed CAA, determined by monitoring the fluorescence of 2′,7′-dichlorofluorescein. Phenolics (25-100 μg/mL) demonstrated a reduction in fluorescence by 37-69% for raw an...

Abstract
31 years old female with a history of contact dermatitis, eczema, allergic rhinitis, pernicious anemia, alopecia areata and latent tuberculosis was treated concurrently with methotrexate along with isoniazid and pyridoxine. Five months into the therapy she developed acute onset jaundice progressing into fulminant liver failure with altered mentation and worsening liver function tests. Extensive workup including serological and histopathological evaluation revealed drug-induced liver injury as the etiology of her liver failure and she...

A sustainable approach to produce activated carbons from pecan nutshell waste for environmentally friendly supercapacitors
Publication date: July 2019Source: Carbon, Volume 148Author(s): D.C. Martínez-Casillas, I. Mascorro-Gutiérrez, C.E. Arreola-Ramos, H.I. Villafán-Vidales, C.A. Arancibia-Bulnes, V.H. Ramos-Sánchez, A.K. Cuentas-GallegosAbstractActivated carbons are key electrode materials for supercapacitors (SCs) widely used in commercial devices. Here we investigate the preparation of activated solar carbons (ASCs) from pecan nutshell waste for their use as electrode materials for SCs. The ASCs are prepared using a sustainable process where concentrated solar energy is used as heat source for the one-step carbonization/chemical activa...

Validation of Enterococcus faecium as a surrogate for Salmonella under different processing conditions for peanuts and pecans.
Abstract
Food Safety and Modernization Act (FSMA) Preventive Control rules require nut processors validate thermal processes to ensure a desirable log reduction of Salmonella is achieved. Due to the complex nature of nut and nut products, processes and equipment, it is difficult to use one validation study for all and may requires individual equipment be validated at the plant level. In plant validation studies, pathogens such as Salmonella cannot be used due to the risk of contamination, thus the suitability of a non-pathogenic organism, Enterococcus faecium as a surrogate for Salmonella was evaluated for...

The effect of nuts and oilseeds enriching on the quality of restructured beef steaks
The objective of the study was to determine the effect of enrichment of restructured beef steaks with various types of nuts and oilseeds on their quality. According to our results, the addition of nuts and oilseeds affected the quality of the various features of the products. Among the studied nuts and oilseeds, flaxseeds showed the most adverse effect on the quality of the product. It caused, i.a.: significant (P < 0.05) increase in cooking loss (from control 12.2–14.9%), reduction of shear force (from control 91.5 to 35.6 N) and penetration force (from control 47,7–19.1 N), color change (increase L*, a*, b* p...
