Health hazards with electromagnetic radiation

International Journal of Pharmaceutical Investigation 2018 8(4):157-163

Electromagnetic spectrum (EMS) is the range of frequencies of electromagnetic radiation (EMR). In general, EMR can be classified into ionizing or nonionizing radiation (NIR), based on their energy possessed to knock electrons off atoms that it interacts with. Ionizing radiation holds a great number of energy to knock off electrons and ionize the matter, whereas NIR does not possess enough energy to ionize atoms or molecules. Ionizing radiation can be further divided into five types, namely, alpha-particles, beta-particles, gamma-ray, X-rays, and neutron particles. NIRs are part of EMS encompass the wavelength (>100 nm), low photon energy (<12.4 eV) portion of the EMS from 1 Hz to 3 × 1015 Hz. NIR is divided into four regions, namely, static electric and magnetic field, extremely low-frequency filed, radiofrequency, and microwave radiation and optical radiation. NIR can be from both natural (e.g., sunlight) and man-made sources (e.g., wireless communications devices). EMR exposures can be divided into three categories, which is high-level, medium-level, and low-level exposure. High-level radiation exposure can cause damage to the body, and the affected cells cannot repair fast enough with a dose that may quickly kill the exposed person. EMR is hazardous to all living organisms because its effects are latent, painless, and cumulative. The current review is to summarize the effect of EMR exposures on physical and mental health.

Aim: The present study aimed to perform scientometric assessment of global publications output of research on Azadirachta indica during 1997–2016. Methodology: The present study examined 4900 global publications on A. indica, as indexed and covered in international Scopus database during 1997–2016 with a view to understanding their growth rate, global publication share, citation impact, international collaborative papers share, distribution of publications by broad subjects, productivity and citation profile of top organizations and authors, preferred media of communication, and bibliographic characteristics of high cited papers. Results: The global publications registered 7.61% annual average growth rate, and its citation impact averaged to 13.91 citations per paper. The global share of top 10 countries ranged from 1.91% to 31.04%, with the largest share (53.49%) from India, followed by Brazil (6.12%), USA (6.02%), etc., About 86.82% and 85.81% of the cumulative global publication and citation share comes from top 10 countries during 1997–2016. The cumulative global share of top 10 countries increased from 85.89% to 86.35% from 1997–2006 to 2007–2017. Only top three countries registered relative citation index above the world average of 1.0: UK (1.95), USA (1.71), and Germany (1.42) during 1997–2016.

International Journal of Pharmaceutical Investigation 2018 8(4):182-191

Aim: The present study is aimed on to perform Scientometric assessment of global publications output of research on nano-enabled drug delivery (NEDD) during 1995–2018. Materials and Methods: A quantitative and qualitative description of NEDD research in India is presented here based on measures such as growth rate, global publications share, share of international collaborative papers, citations per paper, and highly cited papers. It was examined India's research output on NEDD on a series of bibliometric indicators. Results: India published a total of 5897 publications in 24 years during 1995–2018, registering an average annual growth rate of 42.99%, citation impact of 22.90 citations per paper, global publication share of 11.11%, and international collaborative publication share of 20.35%. Profiles global publication output and share of top 10 most productive countries in NEDD research, 20 most productive Indian organizations and 20 most productive Indian authors on a series of indicators including publications output, number of citations, the relative citation index, citations per paper, h-index, and share of international collaborative papers during 1995–2018. Conclusion: This study describes the scattering of research output of India across source journals and distribution of research by subject areas that intersect with NEDD research. It suggests the need for India to develop specific plans of action and ensure its implementation at the national level and also prioritize national goals for NEDD research.

International Journal of Pharmaceutical Investigation 2018 8(4):192-199

Background: Malathion is the most organophosphates which are capable to produce free radicals and induce disturbance in body antioxidant. Resveratrol is an herbal polyphenol and it has been beneficial antioxidant effects during short-term administration. This study was designed to evaluate the effects of resveratrol against damage induced by malathion to the kidneys of rats. Materials and Methods: Forty-eight Wistar rats divided randomly into eight groups (n = 6): sham (saline) and malathion control treated groups (27 mg/kg); resveratrol groups (2, 8, and 20 mg/kg); and resveratrol + malathion-treated groups (2, 8, and 20 mg/kg). Treatments were administered intraperitoneally and gavage daily for 45 days. Parameters related to the function and the histology of the kidneys were evaluated and statistically analyzed from kidney and blood serum samples in respect of the groups. Results: Malathion administration increased significantly Bowman's space, qualitative histopathology indices, kidney malondialdehyde (MDA) level, blood urea nitrogen (BUN), creatinine, and nitrite oxide levels and decreased significantly total antioxidant capacity (TAC) level and diameter and number of renal corpuscles compared to the Sham group (P < 0.001). The resveratrol and resveratrol + malathion treatments in a dose-dependent manner reduced significantly Bowman's space, qualitative histopathology indices, kidney MDA level, BUN, creatinine, and nitrite oxide levels and increased significantly TAC level and diameter and number of renal corpuscles compared to the malathion control group (P < 0.001). Conclusion: It seems that resveratrol administration in a dose-dependent manner improved kidney injury induced by malathion in rats.

Objective: Diarrhea is the second leading cause of death in children. Therefore, the aim of this study was to investigate the effect of probiotics in the treatment of acute noninflammatory diarrhea in children aged 2–10 years in the Pediatric Ward of Hajar Hospital in Shahrekord. Methods: This clinical trial was performed on 184 children with diarrhea. Eighty-six children were randomly assigned to the KidiLact probiotic group and 87 ones to the control group. Patients' demographic information, symptoms, and other variables were recorded in a checklist. The data were analyzed by SPSS version 16 (Chicago, IL) using Chi-square and independent t-test. Results: The mean frequency of diarrhea in the 2nd and 4th days (P < 0.001), duration of fever (P = 0.01), duration of diarrhea (P < 0.001), and duration of hospital stay (P = 0.001) were significantly lower in the probiotic group than those in the control group. The frequency of recovery in the 2nd (P = 0.013) and 4th (P < 0.001) days was significantly higher in the probiotic group than that in the control group. There was no significant difference in the frequency of dyspepsia between the patients of the two groups (P = 0.331). Conclusion: Probiotics are effective in the treatment of acute noninflammatory diarrhea in children aged 2–10 years and can be used as a safe treatment alongside the standard treatment.

Olecranon bursa is the commonly involved structure of the elbow joint in trauma of any mechanical cause or infections due to its subcutaneous position. The overall incidence may vary, but it is more common in males between 30 and 60 years. Various pharmaceutical and physiotherapeutic treatment options are available based on septic or nonseptic conditions. Mostly antibiotics and nonsteroidal anti-inflammatory drugs are widely used by physicians, whereas electrotherapy modalities are the choice of treatment by physiotherapists. Among which, ultrasound (US) therapy is found to be more convenient and effective in treating bursitis. As of the recent evidence available, US therapy is highly effective in treating olecranon bursitis.
