The hepatoprotective effect of Annona muricata and Polyalthia cerasoides (Annonaceae) were monitored by estimating the serum transaminases (SGOT and SGPT), serum alkaline phosphatase (SALP), liver and brain lipid peroxidation (LOP) and their total protein content. Both drugs at a dose of 100 μg/kg significantly prevented the increase in serum transaminases, SALP, liver and brain LOP and decreas...
In our previous studies (Li and Zhong, 2021a; Li 2021b), the commonly reported issue that most of existing mapped WENO schemes suffer from either losing high resolutions or generating spurious oscillations in long-run simulations hyperbolic problems has been successfully addressed, by devising improved schemes, namely MOP-WENO-X, where “X” stands for version scheme. However, all MOP-WENO-X brin...
In 2004 Newman [43] suggested a semidefinite programming relaxation for the Linear Ordering Problem (LOP) that is related to the semidefinite program used in the Goemans-Williamson algorithm to approximate the Max Cut problem [22]. Her model is based on the observation that linear orderings can be fully described by a series of cuts. Newman [43] shows that her relaxation seems better suited for...
Loss of photoreversibility (LOP) of the ultraviolet (UV) damage which prevents reinitiation of deoxyribonucleic acid (DNA) replication occurred with incubation of Escherichia coli B/r thy trp cultures after UV doses of 240, 320, and 400 ergs/mm(2). LOP occurred at the time of reinitiation of DNA replication in the cultures (i.e., after postirradiation lag periods of 45 min or more). Neither the...
Recently, Windey, Gevers, and Cleeremans (2013) proposed a level of processing (LoP) hypothesis claiming that the transition from unconscious to conscious perception is influenced by the level of processing imposed by task requirements. Here, we carried out two experiments to test the LoP hypothesis. In both, participants were asked to classify briefly presented pairs of letters as same or diff...
This paper discusses the potential problems due to cultural differences, which foreign companies may face in Malaysia concerning information security. Top five investing countries in Malaysia: Japan, US, Singapore, Germany and UK are examined. Potential problems concerning people management are developed by using Geert Hofstede’s and Edward Hall’s cultural frameworks. Analyzed are the problems ...
BACKGROUND This study investigated gender dependent differences by the comparison of periodontal status and oral hygiene between diabetic patients and non-diabetic subjects. METHODS 517 mostly obese subjects (171 non-diabetic, 205 type 2 diabetic with oral and 141 with insulin therapy; mean: 59 years) completed an oral hygiene questionnaire and had a clinical examination, including periodonta...
RATIONALE The impact of prevention strategies and risk factors for early-onset (EOP) versus late-onset (LOP) ventilator-associated pneumonia (VAP) are still debated. OBJECTIVES To evaluate, in a multicenter cohort, the risk factors for EOP and LOP, as the evolution of prevention strategies. METHODS 7,784 patients with mechanical ventilation (MV) for at least 48 hours were selected into the ...
In order to evaluate traits related to drought stress in eight sesame (sesamum indicum L.) genotypes, two experiments were carried out in randomized complete design with three replications in the field of the Research Station of College of Agriculture, Shiraz University, Iran. The two experiments differed with respect to their irrigation regimes. Yield related traits (number of days to maturati...
Ant-based algorithms are successful tools for solving complex problems. One of these problems is the Linear Ordering Problem (LOP). The paper shows new results on some LOP instances, using Ant Colony System (ACS) and the StepBack Sensitive Ant Model (SB-SAM).
