BACKGROUND Patients with peripheral artery disease and associated intermittent claudication can experience significant short-term (for instance, day-to-day) variations in their walking ability. This variability is often viewed as a complication in establishing reliable baseline walking performance levels for individual patients in multi-patient supervised walking programs. METHODS In contrast, the present five-month-long quantified community walking program deliberately focuses on the variability referred to above, searching for its causes. I designed this program to have its training regimen evolve based upon short-term correlations of my daily activities with intermittent claudication. In each walking session in my community, I measured the maximum amount of time I could walk before being stopped by intolerable calf pain and then immediately following that, the amount of time required to recover from that pain, repeating this cycle as many times as I could. I also kept track of the total distance that I covh no need to rest at all in 6.6 (0.3) km covered at an average speed of 3.8 (0.1) km/hr. CONCLUSIONS This research indicates that there can be significant motivational and performance benefits to bringing patients' own perspectives more fully into the design and execution of individualized, quantified community walking programs. OBJECTIVE To establish a murine abdominal aortic aneurysm rupture model using a combination of elastase treatment and angiotensin II infusion. METHODS The murine abdominal aorta was treated with elastase. Angiotensin II was infused at a dose of 1000 ng/kg/min via an osmotic pump placed subcutaneously. A saline osmotic pump was used as the control. The aortas were harvested from the mice 4 weeks later, or earlier if mice died. The abdominal aorta was inspected using ultrasound and microscopy for aneurysm formation and/or signs of rupture. The aneurysm outcome was measured using aortic expansion and proinflammatory cytokine expression. It was also compared with the established conventional elastase perfusion and angiotensin II infusion abdominal aortic aneurysm models. RESULTS By day 28 after surgery, all abdominal aortas of mice treated in the modified group had dilated and progressed to abdominal aortic aneurysms with 60% ruptured aneurysms, whereas none of the control aortas treated with saline became aneurysmal. In mice treated with elastase solution alone, 100% developed aneurysms and only one had a ruptured aneurysm. In mice given angiotensin II infusion alone, 37.5% developed aneurysms and none had a ruptured aneurysm. Histological examination of the modified murine abdominal aortic aneurysm rupture model was identical to those observed in the conventional elastase model. Quantitative polymerase chain reaction analysis revealed similarly increased levels of proinflammatory cytokines. this website CONCLUSIONS We modified two current murine abdominal aortic aneurysm models to develop a murine abdominal aortic aneurysm model with consistent aneurysm formation and high rupture incidence, which can be used for studying abdominal aortic aneurysm rupture and treatment. Cancer cells undergo metabolic reprogramming to sustain their own survival under an environment of increased energy demand; however, the mechanism by which cancer cells ensure survival under glucose deprivation stressed conditions remains elusive. Here, we show that deprivation of glucose, dramatically activated the glycogen pathway, accompanied by elevated phosphoglucomutase 1 (PGM1) expression. We further identified that AMP-activated protein kinase (AMPK) stimulated PGM1 expression by inducing histone deacetylase 8 (HDAC8) phosphorylation. Moreover, we demonstrated that glucose deprivation-induced AMPK activation stimulated the translocation of HDAC8 from the nucleus to the cytoplasm, consequently disrupting the binding between HDAC8 and histone 3. PGM1 expression was also found to be critical for lung cancer glycolysis, the oxidative pentose phosphate pathway, and oxidative phosphorylation under glucose deprivation conditions, and further led to the aberrant expression of metabolic enzymes involved in glucose metabolism mediated by ERK1/2. Finally, PGM1 was found to be highly expressed in lung cancer tissues from patients, which correlated with a poor prognosis. Taken together, these results revealed that AMPK activation by glucose deprivation leads to enhanced PGM1 expression, an essential component of the metabolic switch, to facilitate cancer progression, suggesting PGM1 as promising anti-cancer treatment targets. We have reported that E6F6, a mouse monoclonal antibody, is a promising treatment option for patients with chronic hepatitis B (CHB). A humanized E6F6 antibody B11 with affinity loss was obtained by CDR-grafting approach. To address this issue, in silico affinity maturation through scanning mutagenesis using CHARMM force field methods was performed on an predicted immune complex model of the B11HBsAg. We chose four variants with top increased interaction energy for further characterization. The antibody huE6F6-1 within two point mutations (Heavy Chain Asp65Val; His66Leu) was identified to restore the parental antibody's high binding affinity, neutralization activity, and potent efficacy of viral suppression in vivo. Crystal structure (1.8 Å resolution) based molecular docking proved more stabilized and compact hydrogen bond interactions formed in huE6F6-1.The smaller and dispersed HBV immune complexes of huE6F6-1 by electron microscopy suggested it will have the same therapeutic efficacy as the parental E6F6 mAb. Preclinical study and pharmacokinetics of huE6F6-1 demonstrated that it is a stable and desirable lead candidate to improve the clinical management of CHB. Notably, our structure guided approach may facilitate the humanization and affinity maturation of other rodent antibody candidates during drug development. V.BACKGROUND & AIMS Quantification of anti-HBs and anti-HBc predicts the risk of HBV reactivation (HBVr) in lymphoma patients receiving rituximab treatment. However, it remains unclear whether the quantification is predictive of HBVr in leukemia patients undergoing immunosuppression. METHODS and patients Clinical and laboratory data of the leukemia patients with resolved HBV infection diagnosed between January 2013 and March 2018 were retrospectively collected. Data series of HBV seromarkers and HBV DNA levels before the patients receiving chemotherapy and/or hematopoietic stem cell transplantation (HSCT) and during follow-up duration were analyzed. RESULTS In total, 533 leukemia patients with resolved HBV infection were included. The incidences of HBVr were 5.7% (25/441) and 2.2% (2/92) in patients receiving HSCT and chemotherapy, respectively. In patients receiving HSCT, acute lymphoid leukemia had a significantly higher incidence of HBVr than acute myeloid leukemia (8.9% vs 3.9%, P  less then  0.05). The incidence varied almost zero to 40% due to the differences in the profiles of HBV antibodies.
