Selectively retrieving a subset of previously studied information can cause forgetting of related, nonretrieved information. Such retrieval-induced forgetting (RIF) has typically been attributed to inhibitory control processes. Examining participants with a mean age of about 70 years, previous work reported intact RIF in older adults, suggesting efficient inhibition in older adults’ episodic me...

BACKGROUND Introduction of Xpert® MTB/RIF assay has revolutionalised the diagnosis of tuberculosis (TB) by simultaneously detecting the bacteria and resistance to rifampicin (rif), a surrogate marker for multi-drug resistant TB (MDR-TB) as well as one of the principal first-line anti-tuberculosis drugs. In general, rpoB mutations can be found in 96.1% of rif-resistant Mycobacterium tuberculosis...

An eecient sparse LU factorization algorithm on popular shared memory mul-tiprocessors is presented. Interprocess communication is critically important on these architectures-the algorithm introduces O(n) synchronization events only. No global barrier is used and a completely asynchronous scheduling scheme is one central point of the implementation. The algorithm aims at optimizing the single n...

People often talk to others about their personal past. These discussions are inherently selective. Selective retrieval of memories in the course of a conversation may induce forgetting of unmentioned but related memories for both speakers and listeners (Cuc, Koppel, & Hirst, 2007). Cuc et al. (2007) defined the forgetting on the part of the speaker as within-individual retrieval-induced forgett...

Abstract A hybrid of montmorillonite (Mnt) and rifampicin (RIF) was synthesized the structure stability drug carrier system clarified. Density functional theory calculations involving dispersion corrections (DFT-D3) were performed to characterize interactions acting in interlayer space intercalated with rifampicin. The RIF-Mnt complex determined. Calculations revealed deformation molecular afte...

BACKGROUND In patients with intrathoracic lymphadenopathy, differentiating tuberculosis from sarcoidosis is often difficult. We hypothesized that Xpert MTB/RIF assay, a semi-automated hemi-nested PCR would help in this regard. OBJECTIVE To evaluate the performance of Xpert MTB/RIF in the differential diagnosis of tuberculosis and sarcoidosis. METHODS This was a retrospective analysis of pat...

Banded linear systems with large bandwidths can be solved by similar methods as full linear systems. In particular, parallel algorithms based on torus-wrap mapping and Gaussian elimination with partial pivoting have been used with success. These algorithms are not suitable, however , if the bandwidth is small, say, between 1 and 100. As the bandwidth limits the amount of parallelism available a...

OBJECTIVES To assess the performance of Xpert MTB/RIF, an automated molecular test for Mycobacterium tuberculosis (MTB) and resistance to rifampin (RIF), against smear microscopy and culture method for diagnosis of MTB infection. Methods: This is a retrospective analysis of 103 respiratory and 137 non-respiratory patient specimens suspected of tuberculosis at King Khalid University Hospital, Ri...

Dexamethasone (DEX) is a potent and widely used anti-inflammatory and immunosuppressant glucocorticoid. It can bind and activate the pregnane X receptor (PXR), which plays a critical role as xenobiotic sensor in mammals to induce the expression of many enzymes, including cytochromes P450 in the CYP3A family. This induction results in its own metabolism. We have used a series of transgenic mouse...
