Bone marrow concentrate (BMC), which is enriched in mononuclear cells (MNCs) and platelets, has recently attracted the attention of clinicians as a new optional means for bone engineering. We previously reported that the osteoinductive effect of bone morphogenetic protein-2 (BMP-2) could be enhanced synergistically by co-transplantation of peripheral blood (PB)-derived platelet-rich plasma (PRP). This study aims to investigate whether BMC can effectively promote bone formation induced by low-dose BMP-2, thereby reducing the undesirable side-effects of BMP-2, compared to PRP...

OBJECTIVES: To estimate the impact of hypothetical antimalarial and nutritional interventions (which reduce the prevalence of low midupper arm circumference [MUAC]) on the incidence of low birth weight (LBW). METHODS: We analyzed data from 14 633 pregnancies from 13 studies conducted across Africa and the Western Pacific from 1996 to 2015. We calculated population intervention effects for increasing intermittent preventive therapy in pregnancy (IPTp), full coverage with bed nets, reduction in malaria infection at delivery, and reductions in the prevalence of low MUAC...

BACKGROUND: Acute coronary syndrome (ACS) patients, despite treatment with dual antiplatelet therapy (DAPT), have up to 10% risk of recurrent major adverse cardiac events (MACE) in the short term. METHODS: Here we review studies using more potent antithrombotic agent combinations to reduce this risk, namely triple therapy (TT) with the addition of an oral anticoagulant, PAR-1 antagonist, or cilostazol to DAPT (mainly aspirin and clopidogrel), and discuss the limitations of trials to date...

3-Acetyl-oleanolic acid (3Ac-OA) is a derivative of oleanolic acid (OA), which has shown therapeutic beneficial effects on diabetes and metabolic syndrome. In this study we investigated whether 3Ac-OA exerted beneficial effect on non-alcoholic fatty liver disease (NAFLD) in rats and its potential underlying mechanisms. Treatment with 3Ac-OA (1-100 μmol/L) dose-dependently decreased the intracellular levels of total cholesterol (TC) and triglyceride (TG) in FFA-treated primary rat hepatocytes and human HepG2 cell lines in vitro...

Women with high-AMH levels have an increased risk of ovarian hyperstimulation syndrome (OHSS). Studies have suggested that highly purified menotropin (HP-hMG) Menopur® reduces the risk. We, therefore, studied use of low-dose (112.5 IU/day) HP-hMG in ovulatory and anovulatory patients with high AMH (>32 pmol/L). The primary endpoint was the distribution of patients with appropriate, excessive, and inadequate response (5-14, ≥15, and ≤4 oocytes). Another endpoint was frequency of OHSS. Totally 115 women were included and 78 (67...

BACKGROUND: Average CT has been shown to be more accurate than conventional helical CT in quantitation of the PET data. The risk of CT irradiation of a cardiac implantable electronic device (CIED) causing an adverse event is low and is generally outweighed by the clinical benefit of a medically indicated examination. However, irradiation of CIED over one breath cycle in cine CT scan for average CT could impose risks on a patient who is pacing dependent. The purpose of this study was to demonstrate that low-dose average CT can be safe for CIED...

The design of optimal protocols plays an important role in cancer treatment. However, in clinical applications, the outcomes under the optimal protocols are sensitive to variations of parameter settings such as drug effects and the attributes of age, weight, and health conditions in human subjects. One approach to overcoming this challenge is to formulate the problem of finding an optimal treatment protocol as a robust optimization problem (ROP) that takes parameter uncertainty into account. In this chapter, we describe a method to model toxicity uncertainty...

INTRODUCTION: The fat and protein content can impact late postprandial glycemia; therefore, prolonged insulin boluses for high-fat/-protein meals are recommended for patients with type 1 diabetes on insulin pump therapy. It is not clear how to translate these findings to multiple daily injection (MDI) therapy. We hypothesized that regular insulin with a slower onset and a longer duration of action might be advantageous for such meals. METHODS: Twenty-five patients with well-controlled type 1 diabetes (mean HbA1c 6...

REVIEW
Edward J Calabrese
The interaction of background disease processes with environmental induced diseases has long been an issue of considerable interest and debate with respect to its impact on risk assessment. Whether and to what extent these processes should be considered independent or additive to background has been the principal focus of debate. The concept of hormesis, a biphasic dose response characterized by a low dose stimulation and a high dose inhibition, as framed within the context of post-conditioning, reveal the occurrence of a third type of "background" possibility, that of "subtraction to background"...

Inflammation and oxidative stress are implicated in the development of neurodegenerative diseases. Osthole is a compound that is extracted from She Chuang Zi, which is a type of traditional Chinese medicine. Osthole has previously been demonstrated to exhibit anticancer activities and has a low toxicity. However, to the best of our knowledge, the anti‑inflammatory effects of osthole in microglial cells have not been investigated extensively. The aim of the present study was to investigate the potential protective effects of osthole against inflammation induced by lipopolysaccharide (LPS) in microglial cells...

Phthalocyanines (Pcs) are a group of promising photosensitizers for use in photodynamic therapy (PDT). However, their extremely low solubility and their strong tendency to aggregate in aqueous solution greatly restrict their application. Conjugation of Pc macrocycles with peptide ligands could be a very useful strategy to optimize the physical properties of Pcs not only by increasing their water solubility and reducing their aggregation but also by endowing the conjugates with a tumor-targeting capability. To develop highly potent photosensitizers for tumor PDT, we prepared new peptide-conjugated photosensitizers using silicon Pc (SiPc), which has much higher photodynamic activity than zinc Pcs, as the light activation moiety and the cRGDfK peptide (or simply cRGD) as the peptide moiety...

Rhabdoid tumors, which tend to occur prior to the age of 2 years, are one of the most aggressive malignancies and have a poor prognosis due to the frequency of metastasis. Silibinin, a natural extract, has been approved as a potential tumor suppressor in various studies, however, whether or not it also exerts its antitumor capacity in rhabdoid tumors, particularly with regards to tumor migration and invasion, is unclear. The rhabdoid tumor G401 cell line was used in the present in vitro study. An MTT assay was used to assess the cytotoxicity of silibinin on G401 cells, cell migration was studied using a wound healing assay and a Transwell migration assay, and cell invasion was determined using a Transwell invasion assay...
