Cell- and gene- based therapeutics for periodontal regeneration
Keshava Abbayya, Sameer Anil Zope, Sanjay Naduwinmani, Apurva Pisal, Nagraj Puthanakar
Int J Prev Med
2015, 6:110 (4 November 2015)

Periodontitis is a disease of the periodontium, characterized by loss of connective tissue attachment and supporting the alveolar bone. Therefore, to regenerate these lost tissues of the periodontium researchers have included a variety of surgical procedures including grafting materials growth factors and the use of barrier membranes, ultimately resulting into regeneration that is biologically possible but clinically unpredictable. Recently a newer approach of delivering DNA plasmids as therapeutic agents is gaining special attention and is called gene delivery method. Gene therapy being considered a novel approach have a potential to channel their signals in a very systematic and controlled manner thereby providing encoded proteins at all stages of tissue regeneration. The aim of this review was to enlighten a view on the application involving gene delivery and tissue engineering in periodontal regeneration.

Review Article:
On the occasion of world cancer day 2015; the possibility of cancer prevention or treatment with antioxidants: The ongoing cancer prevention researches
Mahmoud Rafieian-Kopaie, Hamid Nasri
Int J Prev Med
2015, 6:108 (4 November 2015)

On February, 2014 World Cancer Day (WCD) was established to raise alertness of cancer and to encourage its prevention, detection, and treatment. In fact, WCD is celebrated every year on the 4
th
of February all over the world to commemorate all the accomplishments of the WHO. In this paper, we aimed to present the scientific evidence for the role of antioxidants in cancer. Damage to cells by reactive oxygen species, especially the damage to DNA, has been found to play a crucial role in the development of cancer. Exogenous antioxidants can prevent free radical damage associated with cancer development. However, whether or not taking dietary antioxidants can prevent or reduce the risk of developing cancer in humans is not clear. Some researchers have suggested that antioxidants counteract with drugs or toxins, which induce oxidative stress and hence prevent damage to cells or body organs.

Review Article:
Folic acid determination using electrochemical sensors
Leila Mirmoghtadaie, Nahal Shamaeizadeh, Nooshin Mirzanasiri
Int J Prev Med
2015, 6:100 (12 October 2015)
DOI

PMID
:26605021
Folic acid (FA) is a water soluble vitamin that exists in many natural species. The lack of FA causes some deficiencies in the human body, so finding a simple and sensitive method for determining the FA is important. One of the modern techniques which overcome the disadvantages of conventional determination methods is the sensors. Possibility of miniaturization, the development of microfabricated electrochemical (EC) sensors has resulted in high sensitivity, portability, improved performance and spatial resolution, low power consumption, and the opportunity for integration with other technologies made Micro-Electrical-Mechanical Systems-based EC sensors suitable to identify low concentration analytes and microorganisms in a variety of mediums.

Review Article:
Calcium/calmodulin-dependent protein kinase II is a ubiquitous molecule in human long-term memory synaptic plasticity: A systematic review
Negar Ataei, Ali Mohammad Sabzghabaee, Ahmad Movahedian
Int J Prev Med
2015, 6:88 (8 September 2015)
DOI
:10.4103/2008-7802.164831
PMID
:26445635
Background:
Long-term memory is based on synaptic plasticity, a series of biochemical mechanisms include changes in structure and proteins of brain's neurons. In this article, we systematically reviewed the studies that indicate calcium/calmodulin kinase II (CaMKII) is a ubiquitous molecule among different enzymes involved in human long-term memory and the main downstream signaling pathway of long-term memory.
Methods:
All of the observational, case-control and review studies were considered and evaluated by the search engines PubMed, Cochrane Central Register of Controlled Trials and ScienceDirect Scopus between 1990 and February 2015. We did not carry out meta-analysis.
Results:
At the first search, it was fined 1015 articles which included "synaptic plasticity" OR "neuronal plasticity" OR "synaptic density" AND memory AND "molecular mechanism" AND "calcium/calmodulin-dependent protein kinase II" OR CaMKII as the keywords. A total of 335 articles were duplicates in the databases and eliminated. A total of 680 title articles were evaluated. Finally, 40 articles were selected as reference.
Conclusions:
The studies have shown the most important intracellular signal of long-term memory is calcium-dependent signals. Calcium linked calmodulin can activate CaMKII. After receiving information for learning and memory, CaMKII is activated by Glutamate, the most important neurotransmitter for memory-related plasticity. Glutamate activates CaMKII and it plays some important roles in synaptic plasticity modification and long-term memory.

Review Article:
Magnesium, iron, and zinc supplementation for the treatment of attention deficit hyperactivity disorder: A systematic review on the recent literature
Mitra Hariri, Leila Azadbakht
Int J Prev Med
2015, 6:83 (2 September 2015)
DOI
:10.4103/2008-7802.164313
PMID
:26445630
Background:
The etiology of attention deficit hyperactivity disorder (ADHD) is not exactly known and its etiology is multifactorial. The usual treatment for these children is based on pharmacotherapy treatment, although the pharmacotherapy has a high effectiveness in ADHD treatment, it often causes different side effects. Existing evidence suggests that children who receive mineral supplement without considering their age and supplement formula may perform better on different behavioral tests compared with those receiving placebo.
Methods:
In this study, we tried to review the previous evidence regarding the effects of minerals in prevention and management of ADHD. We searched PubMed/Medline, Google Scholar, Ovid, Scopus, and ISI web of science up to June 2013. "iron," "iron supplementation," "magnesium," "magnesium supplementation," "zinc," "zinc supplementation," "attention deficit hyperactivity disorder" were used as the keywords. Totally 11 randomized controlled trials were eligible to be included in the systematic review.
Results:
Our review showed that we don't have any predominant evidence about using mineral supplementation on children with ADHD.
Conclusions:
We need more evidence for indicating the effect of zinc, magnesium, and iron supplementation in the treatment of ADHD among children.

Without pigments, we are nothing. Life presents us with a kaleidoscope of colors. From the green grass of home to a forest's ruddy autumn hues, we are surrounded by living colors. Living things obtain their colors, with few exceptions, from natural pigments. In addition to their role in coloration, natural pigments carry out a variety of important biological functions. Of the various classes of pigments in nature, the carotenoids are among the most widespread and important ones, especially due to their varied functions. Lycopene is a red plant pigment found in tomatoes, apricots, guavas, watermelons, papayas, and pink grapefruits, with tomatoes being the largest contributor to the dietary intake of humans. Lycopene exhibits higher singlet oxygen quenching ability. Due to its strong color and nontoxicity, it is a useful food coloring agent. Moreover, it plays a multifunctional role as a nonsurgical aid in the treatment of oral diseases like leukoplakia, oral submucous fibrosis, lichen planus, oral squamous cell carcinoma, and also prevents the destruction of periodontal tissues. This review article focuses mainly on the role of lycopene in the prevention of various oral diseases.

Review Article:
Effect of school-based interventions to control childhood obesity: A review of reviews
Maryam Amini, Abolghassem Djazayery, Reza Majdzadeh, Mohammad-Hossein Taghdisi, Shima Jazayeri
Int J Prev Med
2015, 6:68 (3 August 2015)
DOI

Effectiveness of school-based interventions to prevent or control overweight and obesity among school children was reviewed for a 11-year period (January 2001 to December 2011). All English systematic reviews, meta-analyses, reviews of reviews, policy briefs and reports targeting children and adolescents which included interventional studies with a control group and aimed to prevent or control overweight and/or obesity in a school setting were searched. Four systematic reviews and four meta-analyses met the eligibility criteria and were included in the review. Results of the review indicated that implementation of multi-component interventions did not necessarily improve the anthropometric outcomes. Although intervention duration is a crucial determinant of effectiveness, studies to assess the length of time required are lacking. Due to existing differences between girls and boys in responding to the elements of the programs in tailoring of school-based interventions, the differences should be taken into consideration. While nontargeted interventions may have an impact on a large population, intervention specifically aiming at children will be more effective for at-risk ones. Intervention programs for children were required to report any unwanted psychological or physical adverse effects originating from the intervention. Body mass index was the most popular indicator used for evaluating the childhood obesity prevention or treatment trials; nonetheless, relying on it as the only indicator for adiposity outcomes could be misleading. Few studies mentioned the psychological theories of behavior change they applied. Recommendations for further studies on school-based interventions to prevent or control overweight/obesity are made at the end of this review.

Review Article:
Cancer screening: Should cancer screening be essential component of primary health care in developing countries?
Saurabh Bobdey, Ganesh Balasubramanium, Abhinendra Kumar, Aanchal Jain
Int J Prev Med
2015, 6:56 (6 July 2015)
DOI
:10.4103/2008-7802.160053
PMID
:26236443
Background:
Cancer is a fatal disease and is on the rise across the globe. In India, breast, cervix and the oral cavity are the leading cancer sites, but, unfortunately, in-spite of availability of screening tools, there is no organized cancer screening program in India. The main objective of this study was to review the performance of various cancer screening modalities in a resource poor setting.
Methods:
MEDLINE and web of science electronic database was searched from January 1990 to December 2013, using keywords such as "breast cancer, cervical cancer, oral cancer and their corresponding mesh terms were also used in combination with Boolean operators OR, AND." Two authors independently selected studies published in English and conducted in India. A total of 16 studies was found relevant and eligible for the review. The data on sensitivity and specificity of various screening tool was extracted and analyzed.
Results:
Most of the reported screening trails in India are on cervical cancer and few on breast and oral cancer screening. The pooled estimates of sensitivity and specificity of cervical cancer screening test such as visual inspection with acetic acid, magnified visual inspection with acetic acid, visual inspection with Lugol's iodine, cytology (Papanicolaou smear) and human papillomavirus deoxyribonucleic acid was found to be 68.76% and 84.02%, 63.27% and 85.43%, 81.86% and 87.03%, 63.25% and 93.17% and 75.04% and 91.66%, respectively. Sensitivity and specificity of clinical breast examination was found to be 94.30% and 94.30%, respectively. Oral cancer screening through visual inspection by trained health care worker was found to have 87.90% sensitivity and 92.05% specificity.
Conclusions:
Our study highlights the availability and success of visual screening tools in early detection and mortality reduction of major neoplasia in resource-poor health care settings and recommends implementation of oral and cervical cancer screening as part of assured primary health care package in developing countries.

Review Article:
Role of heart and its diseases in the etiology of depression according to Avicenna's point of view and its comparison with views of classic medicine
Mohammad Yousofpour, Mohammad Kamalinejad, Mohammad Mahdi Esfahani, Jamal Shams, Hassan Hoshdar Tehrani, Mohsen Bahrami
Int J Prev Med
2015, 6:49 (4 June 2015)
DOI
:10.4103/2008-7802.158178
PMID
:26124946
Background:
Depression is one of the most important medical problems in today's world; despite its high prevalence, its causes unfortunately remain not fully known. Among important issues regarding this is its relation with heart diseases. Based on studies this comorbidity increase morbidity and mortality and leads to worst prognosis. However the cause of such high rate of comorbidity is unclear and instead of efforts to understand this correlation has prompted the medical world to consult other medicinal disciplines, not only to find the answer but also to increase the effectiveness of treatment and decrease its cost.
Methods:
We first reviewed the most important ancient causes for depression mentioned by Avicenna and considered those as the key words for our next step. Then, we made a literature search (PubMed and Scopus) with those key words to find out new scientific findings in modern medicine about the Avicenna's suggestions.
Results:
Avicenna does not regard depression as only a mental ailment, but as a disorder resulted by the involvement of brain, heart and blood. He believed that the main causes of depressive events are rooted in heart diseases; in most cases brain is only affected secondary to the heart. Thus he declared that for the treatment of depressive disorders, the underlying cardiovascular diseases should be considered.
Conclusions:
It is worthwhile to consider the Avicenna's recommended causes of depression and to design future scientific studies based on his suggestions.

Review Article:
The concept of lifestyle factors, based on the teaching of Avicenna (Ibn Sina)
Rasool Choopani, Majid Emtiazy
Int J Prev Med
2015, 6:30 (8 April 2015)
DOI

PMID
:25949780
According to the definition stated in the beginning of the "Al-Qanun fi al-Tibb" (the Qanun of Medicine); medicine is a science, from which one learns the states of the human body; health and disease and what causes them, in order to preserve good health when it exists, and restore it when it is lacking. Based on this issue, Avicenna believes that medical science belongs to all human without any limitation, and maintenance of health is one of its prime objectives. He states that many disorders are related to errors in the 6 factors, which are essential for maintaining health and preventing diseases. Avicenna described these six essential factors (lifestyle factors) in his masterpiece, Qanun of Medicine, as "Asbab-e-Settah-e-Zaruriah." Based on the teaching of Avicenna, the first step for maintaining health and approaches to treatment is modification of lifestyle factors, including of nutrition, physical activity, etc.
