“DNA has proved to be an exquisite substrate to compute at the molecular scale. However, nonlinear computations (such as amplification, comparison or restoration of signals) remain costly in term of strands and are prone to leak. Kim et al. showed how competition for an enzymatic resource could be exploited
in hybrid DNA/enzyme circuits to compute a powerful nonlinear primitive: the winner-take-all (WTA) effect. Here, we first show theoretically how the nonlinearity of the WTA effect allows the robust and compact classification of four patterns with only 16 strands and three enzymes. We then generalize this WTA effect to DNA-only circuits SIS3 and demonstrate similar classification capabilities with only 23 strands.”
“Thoracic mobile aortic mural thrombus (TAMT) of the aortic arch is a rare condition. We report 3 cases of symptomatic TAMT treated with systemic alteplase (tissue Selleck Tipifarnib plasminogen activator [t-PA]) thrombolysis. The first patient was symptomatic with repetitive thromboembolism to the left brachial artery. She was treated with repetitive thrombolysis after surgical embolectomy of the brachial artery. The second patient was symptomatic with splenic infarction and mesenteric ischemia.
She was treated with a single cycle of systemic thrombolysis followed by ileocoecal resection. The third patient presented with a TAMT obstructing the left common carotid artery, causing ischemic stroke. After systemic thrombolysis, a reduction in thrombus size was documented; however, the patient died later, of acute heart failure, during the clinical course. On follow-up 6 months after the incidences, the 2 surviving patients were in good condition and free of thromboembolic events. We show that systemic thrombolytic therapy can be performed successfully in patients with TAMT.”
“Edible oil industries suffer from the problem selleck chemicals of seed meal utilization, which is recognized as a byproduct of edible oil. Present work has investigated production of peptide antioxidants, from oil seed meals to
meet the increasing crave for natural antioxidants in food and pharmaceutical industries. Metalloendopeptidase ‘Protease A Amano 2G’ (Aspergillus oryzae) was used to hydrolyze seed protein isolate in enzyme membrane reactor (EMR) and protein hydrolysate was sequentially fractionated by ultrafiltration to obtain potential peptide fraction. Degree of hydrolysis was varied within enzyme to substrate ratio 0.1-2 g/100 g and hydrolysis time 10-60 min to maximize peptide yield and antioxidant activity of peptides in vitro. Controlled hydrolysis with enzyme dose of 2 g/100 g, exhibited peptide yield of 4.60 +/- 0.08 mg/100 mg meal protein in membrane reactor (DH 30.7%) and 4.23 +/- 0.22 mg/100 mg meal protein in batch mode of hydrolysis (DH 29.3%). Antioxidant potential of peptide fractions were compared with commercial non-peptidic antioxidants and major findings confirm superior activity for protein fragments (IC50-0.
