Question: Context: To investigate whether intracavitary physiotherapy is superior to endometrial scratching in patients with recurrent implantation failure (RIF) after in vitro fertilization/intracytoplasmic sperm injection- embryo transfer (IVF/ICSI-ET) cycles.', 'According to the inclusion criteria defined by our hospital, 63 patients with RIF were included in the retrospective study. 20 patients who received intracavitary physiotherapy were classified into Group A, 8 patients with both intracavitary physiotherapy and endometrial scratching were into Group B, and 35 patients who underwent endometrial scratching were into Group C. The primary outcome measures were implantation and clinical pregnancy rates. The secondary outcome measure was pregnancy outcome.', 'There were no statistical differences in implantation and clinical pregnancy rates between Groups A and C (29.41 vs 35.59 %, 45.00 vs 48.57 % respectively, P > 0.05), Groups B and C (36.36 vs 35.59 %, 50.00 vs 48.57 % respectively, P > 0.05). In addition, no statistical differences were discovered in pregnancy outcomes between Groups A and C (P > 0.05), Groups B and C (P > 0.05).\Question: Is intracavitary physiotherapy inferior to endometrial scratching in patients with recurrent implantation failure?

Answer: Intracavitary physiotherapy is not inferior to endometrial scratching on improving implantation and clinical pregnancy rates in patients with RIF after IVF/ICSI cycles.

Question: Context: We have previously shown that phospholipid oxidation products of 1-palmitoyl-2-arachidonoyl-sn-glycero-3-phosphorylcholine (ox-PAPC) inhibit lipopolysaccharide (LPS)-induced E-selectin expression and neutrophil binding in human aortic endothelial cells (HAECs). The current studies identify specific phospholipids that inhibit chemokine induction by Toll-like receptor-4 (TLR4) and -2 (TLR2) ligands inECs and macrophages.', 'Measurements of interleukin (IL)-8 and monocyte chemotactic protein-1 levels secreted from ox-PAPC- and LPS-cotreated ECs indicate that ox-PAPC inhibits activation of TLR4 by LPS. The effects of IL-1beta and tumor necrosis factor-alpha, which utilize the same intracellular signaling molecules, were not inhibited. Cell fractionation and immunofluorescence analyses demonstrate that LPS induces membrane translocation of the LPS receptor complex to a lipid raft/caveolar fraction in ECs. Ox-PAPC inhibits this translocation and alters caveolin-1 distribution. Supporting an important role for caveolae in LPS action, overexpression of caveolin-1 enhanced LPS-induced IL-8 synthesis. Ox-PAPC also inhibits the effect of TLR2 and TLR4 ligands in human macrophages.\Question: Do specific phospholipid oxidation products inhibit ligand activation of toll-like receptors 4 and 2?

Answer: These studies report a novel mechanism that involves alterations to lipid raft/caveolar processing, by which specific phospholipid oxidation products inhibit activation by TLR4 and TLR2 ligands. These studies have broader implications for the role of ox-PAPC as a regulator of specific lipid raft/caveolar function.

Question: Context: The extent of ischemic injury in response to cerebral ischemia is known to be affected by native vasculature. However, the nonvascular and dynamic vascular responses and their genetic basis are not well understood.', 'We performed a genome-wide association study in 235 mice from 33 inbred strains using the middle cerebral artery occlusion model. Population structure and genetic relatedness were accounted for using the efficient mixed-model association method. Human orthologs to the genes associated with the significant and suggestive single-nucleotide polymorphisms from the mouse strain survey were examined in patients with M1 occlusions admitted with signs and symptoms of acute ischemic stroke.', 'We identified 4 genome-wide significant and suggestive single-nucleotide polymorphisms to be associated with infarct volume in mice (rs3694965, P=2.1710(-7); rs31924033, P=5.6110(-6); rs32249495, P=2.0810(-7); and rs3677406, P=9.5610(-6)). rs32249495, which corresponds to angiopoietin-1 (ANGPT1), was also significant in the recessive model in humans, whereas rs1944577, which corresponds to ZBTB7C, was nominally significant in both the additive and dominant genetic models in humans. ZBTB7C was shown to be upregulated in endothelial cells using both in vitro and in vivo models of ischemia.\Question: Do integrative Mouse and Human Studies Implicate ANGPT1 and ZBTB7C as Susceptibility Genes to Ischemic Injury?

Answer:
Genetic variations of ANGPT1 and ZBTB7C are associated with increased infarct size in both mice and humans. ZBTB7C may modulate the ischemic response via neuronal apoptosis and dynamic collateralization and, in addition to ANGPT1, may serve as potential novel targets for treatments of cerebral ischemia.
