Automated SG-DBR Tunable Laser Calibration Optimized for Optical Coherence Tomography Applications
<p>SG-DBR lasers look to solve many problems associated with present OCT sources by being cost effective, smaller in size, more robust, and by operating at faster repetition rates. Swept Source Optical Coherence Tomography (SS-OCT) requires a tunable laser source that exhibits linear frequency …

Subgroups of the Torelli group
Let Mod(Sg) be the mapping class group of an orientable surface of genus g, Sg. The action of Mod(Sg) on the homology of Sg induces the well-known symplectic representation: <BR> <BR> <center>Mod(Sg) ---> Sp(2g, Z).</center> <BR> The kernel of this representation is called the Torelli group, I(Sg). …

A NOVEL MAGNETIC THREE-DIMENSIONAL LEVITATED PRIMARY CELL CULTURE SYSTEM FOR THE DEVELOPMENT OF IN VITRO SALIVARY GLAND-LIKE ORGANOIDS
Salivary gland (SG) hypofunction and dry mouth leads to oral complications and impaired quality of life. Recently, researchers have proposed to repair hypo-functional SG via various cell-based approaches in three-dimensional (3D) scaffold-based systems. The majority have nonhuman-based components. …

Ο ρόλος της σεργλυκίνης στη ρύθμιση του συμπληρώματος και στην έκφραση των μεταλλοπρωτεϊνασών σε μυελωματικά πλασματοκύτταρα: βιοχημική, μοριακή και κλινικοεργαστηριακή προσέγγιση
Η σεργλυκίνη (SG) είναι μια πρωτεογλυκάνη που εκφράζεται και εκκρίνεται από το σύνολο σχεδόν των αιμοποιητικών κυττάρων, ενώ αποτελεί την κύρια πρωτεογλυκάνη η οποία εκκρίνεται από τις κυτταρικές σειρές πολλαπλού μυελώματος (ΠΜ). Έχει βρεθεί ότι η SG συμμετέχει στη ρύθμιση πληθώρας παραγόντων που …

Sam68, Stress Granules, and translational control of HIV-1 nef mRNA
… macromolecular structure called stress granules (SG). In addition, we demonstrated that these variants bound to nef mRNA in a sequence-specific manner. Furthermore, we showed that these variants co-localized with nef mRNA in SG. Importantly, we validated these findings in the context of HIV-1 …

The Role of Streptococcus Gallolyticus Subspecies Gallolyticus In Colon Cancer Development
… may play a role in the development of CRC. <em>Sg</em>, formerly S. <em>bovis </em>biotype I, has been shown to be highly associated with CRC. In observing patients with either <em>Sg </em>bacteremia or endocarditis it was found that 25-80% of patients with <em>Sg </em>bacteremia had tumors and …

Double Minority Youth Mental Health: An investigation of challenges and opportunities to support Chinese sexual/gender minority young people in New Zealand
Objectives: Most research on sexual and gender (SG) minority mental health has been conducted with European (White) populations in the United States. Very little is known about the mental health needs and challenges faced by young people who are both ethnic and SG minorities (i.e. those who are not …

Soil Organic Carbon Sequestration Potential by Perennial Biomass Crops in Southern Ontario, Canada
Switchgrass (Panicum virgatum, SG) and Miscanthus (Miscanthus spp., Mis), C4 perennial biomass crops (PBCs), are being cultivated in Ontario, Canada, on degraded agricultural (Ag) fields to enhance soil organic carbon (SOC) sequestration. This study assessed SOC stocks in SG and Mis fields compared …

Measurement and Analysis of Calcium-Dependent Exocytosis in Giant Excised Membrane Patches
… recordings show that secretory granules (SGs) containing serotonin are mostly lost from excised patches. Small vesicles that are retained (non-SGs) do not contain substances detected by amperometry. Non-SG fusion is reduced by tetanus toxin light chain treatment, however, it is unaffected …

Μελέτη της έκφρασης και του ρόλου της σεργλυκίνης στις κακοήθειες
Η σεργλυκίνη (SG) είναι η κύρια πρωτεογλυκάνη που εκφράζεται από τα αιμοποιητικά κύτταρα και συμμετέχει στη ρύθμιση διαφόρων παραγόντων που εμπλέκονται στις αντιδράσεις φλεγμονής. Επιπλέον, φαίνεται ότι διαδραματίζει σημαντικό ρόλο στη βιολογία του πολλαπλού μυελώματος αφού αναστέλλει τη …

Investigating pathological mechanisms in the Thy1-hTDP43 ALS mouse model
… such as the formation of stress granules (SGs). SGs are typically transient structures that sequester translationally-stalled mRNA, RNA-binding proteins, ribosomal components, and translation initiation factors to promote cell survival upon stress induction. In ALS and other …

Agronomic assessment of grazing method of corn residues on cow performance, residue utilization, crop yield, and soil properties
… properties. Two grazing methods (strip grazing, (SG) and continuous grazing, (CG)) and a control (ungrazed, (CT)) were arranged in a randomized complete block design with 3 replications each yr for 3 yr. Within SG, subplots were assigned with a grazing order (1, 2, 3). Thirty-six spring-calving, …

Technoeconomic analysis of a steam generation system with carbon capture
… primarily for the purpose of steam generation (SG). The proposed SMR-MR-SG system converts NG to clean-burning hydrogen (H2), burns H2 to generate steam, and captures and concentrates CO2. Unused NG and H2 are recycled back into the system with uncaptured CO2 to increase efficiency. The …
