timolol is a non-selective beta-adrenergic receptor antagonist administered for treating glaucoma, heart attacks and hypertension. in the present study, we set out to determine whether or not timolol can provoke cataract formation, thus the influence of timolol on the amyloid-type aggregation of crystallin was investigated. we then provided experimental evidence of crystallin aggregation and it...

Aggregation is a sub-task of Natural Language Generation (NLG) that improves the conciseness and readability of the text outputted by NLG systems. Till date, approaches towards the aggregation task have been predominantly manual (manual analysis of domain specific corpus and development of rules). In this paper, a new algorithm for aggregation in NLG is proposed, that learns context sensitive a...

S100 proteins are small dimeric calcium-binding proteins which control cell cycle, growth and differentiation via interactions with different target proteins. Intrinsic disorder is a hallmark among many signaling proteins and S100 proteins have been proposed to contain disorder-prone regions. Interestingly, some S100 proteins also form amyloids: S100A8/A9 forms fibrils in prostatic inclusions a...

Motivated by the previously developed multilevel aggregation method for solving structural analysis problems a novel two-level aggregation approach for efficient iterative solution of Principal Component Analysis (PCA) problems is proposed. The course aggregation model of the original covariance matrix is used in the iterative solution of the eigenvalue problem by a power iterations method. The...

This study was performed to assess the clopidogrel activity in inhibition of platelet aggregation in suspected angina patients on a daily dosag of 75 mg of clopidogrel for at least 7 days. This clinical trial was conducted in the outpatients department of Cardiology, Post graduate Medical Institute, Lady Reading Hospital, Peshawar from 15th October 2007 to 20th December 2007. We included 105 su...

In this paper, we address the problem of data aggregation scheduling problem to minimize the latency in wireless sensor networks (WSNs). An efficient distributed synchronous aggregation scheduling method is proposed to structure a collision-free schedule for data aggregation in WSNs. By using a connected dominating set (CDS) as an aggregation tree, we implement the synchronous aggregation sched...

To solve data aggregation problems, several algorithms have developed to operate efficient networks. However, a current data aggregation still includes a design weakness. This paper proposes to design distributed aggregation for a confidential data using Software Robot (SR) in cluster sensor networks. Software robot of smart software is based on homomorphic encryption to aggregate secure sensin...

A major problem in the formulation of therapeutic proteins is the irreversible protein aggregation. Recombinant human interferon alpha2b (rhIFN2b) has poor stability and undergoes physical degradation. The aim of this study was to investigate the effect of solution conditions on the heat-induced aggregation of rhIFNα2b. The protein was incubated for 1 h at 40°C–70°C and for up to 240 h at 50C...
