[EX Q]: Our previous in-vivo and in-vitro studies demonstrated that inflammation accelerated the progression of atherosclerosis via the dysregulation of the low-density lipoprotein receptor (LDLr) pathway. The current study aimed to investigate the effects and their underlying mechanisms of inflammation on lipid accumulation in the radial arteries of endstage renal disease (ESRD) patients with arteriovenostomy.', '30 ESRD patients with arteriovenostomy were included. The patients were divided into two groups based on their plasma levels of C-reactive protein: a control (n = 16) and an inflamed group (n = 14). The expression of tumor necrosis factor-alpha (TNF-alpha) and monocyte chemotactic protein-1 of the radial arteries were increased in the inflamed group. Foam cell formation and lipid droplet accumulation were examined by hematoxylin and eosin (H & E) and Oil Red O staining. Intracellular cholesterol trafficking-related proteins were examined by immunohistochemistry and immunofluorescent staining.', 'There was significant lipid accumulation in the radial arteries of the inflamed group compared with the control. Further analysis demonstrated that this accumulation was correlated with the increased protein expression of LDLr, sterol regulatory element-binding protein-2 (SREBP-2), and SREBP cleavageactivating protein (SCAP). Confocal microscopy showed that inflammation enhanced the translocation of SCAP escorting SREBP-2 from the endoplasmic reticulum to the Golgi, thereby activating LDLr gene transcription. Interestingly, upregulated LDLr expression was positively associated with the increased protein expression of mammalian target of rapamycin (mTOR), which had enhanced coexpression with SREBP-2. This finding suggests that the activation of mTOR may be involved in LDLr pathway disruption through the upregulation of SREBP-2 expression.
[EX A]: Does activation of mTOR contribute to foam cell formation in the radial arteries of patients with end-stage renal disease?

[EX Q]: To construct phage display library of anti-chymopapain scFv.', 'V(H) and V(L) gene repertoires were amplified from splenocyte mRNA by RT-PCR and joined by a (Gly(4)ser)3 linker to obtain scFv genes. The scFv genes were then cloned into phagemid pFAB5C to construct phage display library. Affinity selection and ELISA were used to identify specific phage antibody to chymopapain.', 'After 4 rounds of panning, high affinity scFv was obtained.

[EX Q]: Existing dogma that a female is born with fixed number of eggs was challenged by the detection of stem cells in adult mammalian ovary. Data has accumulated in support of ovarian stem cells (OSCs) proliferation, maintenance in culture, formation of germ cell nests and differentiation into oocytes and primordial follicle assembly using different strategies.', 'Flow cytometry analysis identified >8\xa0μm OSCs which are DDX1 positive and are considered equivalent to spermatogonial stem cells (SSCs) in testis. Analysis of both ovarian and testicular smears obtained after enzymatic digestion has led to the identification of an additional stem cell population termed very small embryonic-like stem cells (VSELs). VSELs and OSCs/SSCs differ from each other in their size and OCT-4 expression. VSELs express pluripotent markers including nuclear OCT-4 whereas OSCs/SSCs express cytoplasmic OCT-4 suggesting a differentiated state. VSELs can be studied by flow cytometry as small sized cells which are LIN-/CD45-/Sca-1+. We have reported 0.02\u2009±\u20090.008, 0.03\u2009±\u20090.017 and 0.08\u2009±\u20090.03\xa0% of total cells as VSELs in normal, chemoablated and after FSH treatment to chemoablated mouse ovary.
