The serine-rich repeat (SRR) glycoproteins are a family of adhesins found in many Gram-positive bacteria. Expression of the SRR adhesins has been linked to virulence for a variety of infections, including streptococcal endocarditis. The SRR preproteins undergo intracellular glycosylation, followed by export via the accessory Sec (aSec) system. This specialized transporter is comprised of SecA2,...

BACKGROUND We compared the efficacy of microdissection testicular sperm extraction (microdissection TESE) and conventional TESE in patients with non-obstructive azoospermia (NOA) and related the positive sperm recovery to certain variables: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels, testicular volume and histology. METHODS Sperm retrieval rates (SRR) in patients w...

This paper proposes a method for the enhancement of reverberant speech using the knowledge of the excitation source of speech production. The degradation level in the reverberant speech is measured in terms of Speechto-Reverberation component Ratio (SRR). From perception and processing point of view high SRR regions are important. Hence the proposed method identifies and enhances the speech in ...

We present a systematic numerical study, validated by accompanied experimental data, of individual and coupled split ring resonators (SRRs) of a single rectangular ring with one, two and four gaps. We discuss the behavior of the magnetic resonance frequency, the magnetic field and the currents in the SRRs, as one goes from a single SRR to strongly interacting SRR pairs in the SRR plane. We show...

The input workload of an irregular application must be evenly distributed among its threads to enable cutting-edge performance. To address this need in OpenMP, several loop scheduling strategies were proposed. While having this ever-increasing number of strategies at disposal is helpful, it has become a non-trivial task to select the best one for a particular application. Nevertheless, this cha...

Osteoporosis is a disease in which the microarchitecture of bone tissue deteriorates, with consequent loss of bone mass. Strontium ranelate (SrR) is currently used for treatment of the condition. SrR may have a dual effect: anabolic (stimulating pre-osteoblast replication) and anti-catabolic (reducing osteoclastic activity). However, its mechanism of action has not yet been completely elucidate...

d-Serine is an endogenous ligand for NMDARs generated from l-serine by the enzyme serine racemase (Srr). Both neuronal and glial localizations have been reported for d-serine and Srr. 3-Phosphoglycerate dehydrogenase is an exclusively astrocytic enzyme that catalyzes the first committed step of l-serine biosynthesis. Using transgenic mice expressing enhanced green fluorescent protein under the ...

Perl Status Reporter (SRr) [1] is a data mining tool and in this research work we illustrate the use of SRr on spatio-temporal database. Spatio–temporal data are associated with time and space and used vastly in different applications of diversified areas such as geography, geology, city planning, agriculture, environmental study, traffic navigation, aerospace industries, and so on. We exploit ...

Higher spatial resolution imaging data is always desirable to the international community of planetary scientists interested in improving understanding of surface formation processes. We have previously developed a novel Super-resolution restoration (SRR) technique (Tao & Muller, 2016) using Gotcha sub-pixel matching, orthorectification, and segmented 4th order PDE-TV, called GPT SRR, which is ...

Osteoporosis is a bone disease that afflicts millions of people around the world, and a variety of spinal integrity issues, such as degenerative spinal stenosis and spondylolisthesis, are frequently concomitant with osteoporosis and are sometimes treated with spinal interbody fusion surgery. Previous studies have demonstrated the efficacy of strontium ranelate (SrR) treatment of osteoporosis in...
