Data on the effect of lead concomitant noise on oxidative stress in rats

Exposure to chemical and physical factors occur in many occupations. Exposure to ambient pollutants such as noise, heavy metals, drugs enhance free radicals and can cause oxidative stress. The aim of the present project was to investigate noise and lead as two workplace stressors in rats. 20 male rats were assigned into 4 groups randomly. Rats in control group was not exposed to any stressor agent, while the first group was exposed to noise (105 dB, 4 kHz), the second group was exposed to lead acetate (gavage,4 mg/kg), and the last group was exposed to both lead and noise. In order to assess oxidative stress, the serum levels of malondialdehyde (MDA), as a product of lipid peroxidation was measured by thiobarbituric acid and also total antioxidant capacity (TAC) were measured by using ELISA kits. Our research showed significant enhancement in levels of malondialdehyde in exposed groups compare to control group. Also our results showed considerable decrease in levels of TAC in exposed groups compared to control group. Lead and noise exposure for 30 days caused a statistically significant enhancement in MDA level and significant decrease in the serum TAC level. On the other hand, statistically no significant difference was observed between the MDA and TAC levels between exposed groups. Moreover, body weight between exposed groups have decreased compared to control group. The outcomes of this study confirms the effect of noise and lead on lipid peroxidation. However, further studies are needed to clarify the mechanisms of oxidative stress through lead and noise exposure. © 201

The Application of Problem Bassed Learning to Improve Learning Motivation Skills, of Scientific Inquiry and Argumentation Skills of Students SMPN Kediri on the Material Changes and Environmental Pollutan

This study aimed to measure the effectiveness of problem based learning design study on the motivation skills, of inquiry and scientific argumentation skills. This is the type of study design non-equivalent control group design in class VII SMPN 1 Grogol Kediri on 12 up to 23 May 2015 on the material changes and environmental pollutan. Used some of the instruments to support research that motivation questionnaire and inquiry skill rubric (process and product). And rubric scientific argumentation skills are integrated in the cognitive achievement tes. Data tabulated later in the analysis using the program SPSS 16 for windows 2007. The study is showed that: 1) students motivation treatment group (80%) higher than the control group (70%); 2) inquiry skills of the control group with the treatment process is the same (α= 0,181>0,05) but the product of inquiry skills between the two group differed (α= 0,01<0,05); 3) ANACOVA test study showed that the skills of scientific argument between the treatment group and the control group is different (α=0,000<0,05). Concluded that the model of problem-based learning can increase learning motivation, skills of inquiry, the ability of the scientific arguments.

The effects of radiofrequency radiation on mice fetus weight, length and tissues

The public concern of harmful effects of radiofrequency radiation exposure, especially with rapid increase in the use of wireless and telecommunication devices, is increasing. Some studies show fetal and developmental abnormalities as the result of radiofrequency radiation exposure. We aimed to investigate possible teratogenic effects of radiofrequency in 915 MHz on mice fetus and protective role of vitamin C. 21 pregnant mice were divided into 3 groups. Control group was in normal condition without any stressor agent. Exposure group was exposed to 915 MHz RFR (8 h/day for 10 days) and 0.045 µw/cm2 power density. The exposure plus vitamin C group received 200 mg/kg vitamin C by gavage and was exposed to 915 MHz RFR (8 h/day for 10 days) and 0.045 µw/cm2 power density. The fetus weight, C-R length were measured by digital balance and caliper. Tissues were assessed after staining with H & E. Our results showed significant increase in fetus weight and C-R length and also enlarged liver, tail deformation in mice fetus in exposure group. Although usage of vitamin C caused significant decrease in mentioned parameters. The outcome of this study confirms the effects of radiofrequency radiation on growth parameters such as body weight, length and some tissues in mice fetuses and protective effect of vitamin C. However more studies on non-ionization radiation in different frequencies and severity, during pregnancy are needed to clarify the exact mechanisms of these changes and better protection. © 201

The Method of Shaykh Nawawi Al-Banteni in Hadith Commentaries of Tanqih Al-qaul

Shaykh Nawawi al-Banteni is an Islamic scholar who produces various famous works in the archipelago, especially in Indonesia.

Potential of durian seed (Durio zibenthinus Murr.) flour as the source of eco-friendly plastics materials: a mini-review

Currently, plastics from non-renewable sources are being used less due to environmental concerns and switching to eco-friendly plastics. Eco-friendly plastics are usually produced from renewable materials, such as durian seed flour (DSF). DSF is a product made from durian seeds, and currently, it is only limited to a substitute for other ingredients in food products systems. However, DSF contains specific constituents that can be used to create eco-friendly plastics, rarely discussed. Thus, this mini-review briefly discusses the chemical composition and potential of DSF as a source of eco-friendly plastic materials
