We investigated the optical properties of colloidal-synthesized ZnO spherical nanoparticles prepared from 1-octadecene (OD), a mixture of trioctylamine (TOA) and OD (1:10), and a mixture of trioctylphosphine oxide (TOPO) and OD (1:12). It is found that the green photoluminescence (PL) of samples from the mixture of TOA/ OD and TOPO/OD is largely suppressed compared with that from pure OD. Moreo...

Studies were conducted in rats to determine the effect of maternal diabetes and the consequent hyperglycemia on cardiovascular function in the offspring. Diabetes was induced in pregnant Wistar rats through streptozotocin injection (50 mg/kg). Cardiovascular parameters were measured in 2-mo-old offspring animals of diabetic (OD, n=12) and control rats (OC, n=8). Arterial pressure (AP), heart ra...

objectives : stem cell (sc) therapy is a promising technique for tissue regeneration. this study aimed to compare the viability and proliferation ability of periodontal ligament stem cells (pdlscs) isolated from the periodontium of healthy and periodontitis-affected teeth to obtain an autologous, easily accessible source of scs for tissue regeneration in periodontitis patients. materials and me...

background: atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. oxidized low-density lipoprotein (oxldl) is considered as an important determining factor in the pathogenesis of atherosclerosis. objective: the purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

We assessed the blockade of the renin-angiotensin system (RAS) achieved with 2 angiotensin (Ang) antagonists given either alone at different doses or with an ACE inhibitor. First, 20 normotensive subjects were randomly assigned to 100 mg OD losartan (LOS) or 80 mg OD telmisartan (TEL) for 1 week; during another week, the same doses of LOS and TEL were combined with 20 mg OD lisinopril. Then, 10...

Research in discourse processing has identi ed two representational requirements for discourse planning systems. First, discourse plans must adequately represent the intentional structure of the utterances they produce in order to enable a computational discourse agent to respond e ectively to communicative failures [15]. Second, discourse plans must represent the informational structure of utt...

This paper proposes a holistic equilibrium theory of organizational development (OD). The theory states that there are three driving forces in organizational change and development—rationality, reality, and liberty. OD can be viewed as a planned process of change in an organization so as to establish equilibrium among these three interacting forces. Existing OD theories, concepts and their impl...

The diameter diam(H) of a (directed) graph H is the maximum value computed over the lengths of all shortest (directed) paths in H . Given a bridgeless connected graph G, the oriented diameter OD(G) is given by OD(G) = min{diam(H) : H is an orientation of G}. In this paper, we show that OD(G) ≤ 2diam(G) +1 for every connected bridgeless interval graph G. Further, for every 2-connected proper int...

BACKGROUND There is no consensus on the optimal form of venous thromboembolic prophylaxis treatment in hip and knee arthroplasty patients, or on the safety and complication profile of the available chemical prophylaxis modalities. In this study we aimed to measure the return to theatre rate for any cause related to wound complications in patients undergoing total hip replacement and total knee ...

Microwave irradiation, as opposed to formalin exposure, has not routinely been used in the preparation of killed vaccines despite the advantages of decreased chemical toxicity, ability to kill cells quickly, ease of completion requiring only a standard microwave, and potential increased protein conservation during irradiation. We evaluated the potential of microwave irradiation versus formalin ...
