Hepatocyte transplantation is an alternative to whole liver transplantation. Yet, efficient liver repopulation by transplanted hepatocytes is low in livers of old animals. This restraint might be because of the poor proliferative capacity of aged donor hepatocytes or the regenerative impairment of the recipient livers. The age-dependent liver repopulation by transplanted wild-type hepatocytes was investigated in juvenile and senescent rats deficient in dipeptidyl-peptidase IV. Repopulation was quantified by flow cytometry and histochemical estimation of dipeptidyl-peptidase IV enzyme activity of donor cells in the negative host liver...

An endoplasmic reticulum (ER)-resident protein that regulates cytosolic and ER free-Ca(2+) concentration by induction of store-operated calcium entry. That is the original definition of STIM2 and its function. While its activity strongly depends on the amount of calcium stored in the ER, its function goes further to intracellular signalling and gene expression. Initially undercovered by the prominent function of STIM1, STIM2 became to be vital in mice, gradually emerging as an important player in the nervous system, and cooperating with STIM1 in the immune system...

Alongside the rapid growth in aging populations worldwide, prevention and therapy for age-related memory decline and dementia are in great demand to maintain a long healthy life. Here we found that iso-α-acids, hop-derived bitter compounds in beer, enhance microglial phagocytosis and suppress inflammation via activation of the peroxisome proliferator-activated receptor (PPAR-γ). In normal mice, oral administration of iso-α-acids led to a significant increase both in CD11b and CD206 double-positive anti-inflammatory type microglia (P<0...

Life is maintained through alternating phases of cell division and quiescence. The causes and consequences of spontaneous mutations have been extensively explored in proliferating cells, and the major sources include errors of DNA replication and DNA repair. The foremost consequences are genetic variations within a cell population that can lead to heritable diseases and drive evolution. While most of our knowledge on DNA damage response and repair has been gained through cells actively dividing, it remains essential to also understand how DNA damage is metabolized in cells which are not dividing...

OBJECTIVES: Stakeholder engagement and public involvement are considered as integral to developing effective public health interventions and is encouraged across all phases of the research cycle. However, limited guidelines and appropriate tools exist to facilitate stakeholder engagement-especially during the intervention prioritisation phase. We present the findings of an online 'Delphi' study that engaged stakeholders (including young people) in the process of prioritising secondary school environment-focused interventions that aim to increase physical activity...

OBJECTIVE: To synthesis the qualitative studies of children's experiences of chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME). DESIGN: Systematic review and meta-ethnography. BACKGROUND: CFS/ME is an important disabling illness, with uncertain cause and prognosis. As a result, children with CFS/ME can find themselves living with greater uncertainty and stigma, exacerbating the impact of the condition. There is a growing body of qualitative research in CFS/ME, yet there has been no attempt to systematically synthesis the studies involving children...

Outcomes for acute myeloid leukemia (AML) patients who fail to achieve complete remission remain poor. Hematopoietic cell transplantation (HCT) has been shown to induce long-term survival in AML patients with active disease. HCT is largely performed with HLA-matched unrelated or HLA-matched related donors. Recently, HCT with HLA-haploidentical related donors has been identified as a feasible option when HLA-matched donors are not immediately available. However, there is little data comparing outcomes of AML patients with active disease who receive haploidentical versus traditionally matched HCT...

Current conditioning regimens provide insufficient disease control in relapsed/refractory acute leukemia (AL) patients undergoing hematopoietic stem cell transplantation (HSCT) with active disease. Intensification of chemotherapy and/or total body irradiation (TBI) is not feasible because of excessive toxicity. Total marrow and lymphoid irradiation (TMLI) allows for precise delivery and increased intensity treatment via sculpting radiation to sites with high disease burden or high risk for disease involvement, while sparing normal tissue...

Oxidant stress contributes to the initiation and progression of hypertension (HTN) by enhancing endothelial dysfunction and/or causing perturbations in nitric oxide homeostasis. Differences in mitochondrial function may augment this process and provide insight into why age of onset and clinical outcomes differ among individuals from distinct ethnic groups. We have previously demonstrated that variation in normal mitochondrial function and oxidant production exists in endothelial cells from individuals of Caucasian and African-American ethnicity and that this variation contributes to endothelial dysfunction...

BACKGROUND: Resident loved ones of patients with COPD can play an important role in helping patients to engage in physical activity. We aimed to compare activity levels and exercise motivation between COPD patients and their resident loved ones; to compare the same outcome measures in patients after stratification for the physical activity level of the loved ones; and to predict the likelihood of being physically active in patients with a physically active resident loved one. METHODS: 125 patient-loved one dyads were cross-sectionally and simultaneously assessed...

Ischemic postconditioning (PostC) is defined as a series of rapid intermittent interruptions of blood flow at the phase of reperfusion, which produces neuroprotection against cerebral ischemia/reperfusion injury via mobilizing the brain's own endogenous adaptive mechanisms. Now the concept of conventional ischemic PostC has been extended to limb remote ischemic PostC and chemical PostC with hypoxia, volatile anesthetic, CO2, etc. According to the different temporal profile of PostC, it is divided into rapid and delayed PostC...

CD28 is well characterized as an essential co-stimulatory receptor critical for activation, proliferation and survival processes in CD4(+) T cells. Populations of CD4(+)CD28(null) T cells, with apparently contradictory physiological roles, have recently been reported, along with the co-expression of the NK activating receptor NKG2D, in autoimmune diseases and chronic viral inflammation. Paradoxically, studies in cancer suggest that an expanded CD4(+)NKG2D(+) population may be armed with immunosuppressive properties...

INTRODUCTION: Denosumab specifically inhibits the receptor activator for nuclear factor-kappa B ligand (RANKL), and prevents osteoporotic fractures. Several reports have analyzed the effects of denosumab and alendronate alone on bone mineral density (BMD) or reduction of fracture risk. The objective of this study was to analyze the effects of antiresorptive osteoporosis pharmacotherapy on pain relief in patients with fresh vertebral fracture. METHODS: This retrospective, single-center study included 80 patients (10 males, 70 females) with fresh osteoporotic vertebral fractures treated using denosumab at a dose of 60 mg subcutaneously every 6 months (40 patients) or alendronate at a dose of 35 mg orally every week (40 patients) for 6 months in our hospital...
