Cadmium (Cd)-induced tissue injury depends on the accumulated Cd which differentially affects endogenous iron (Fe). To investigate this, adult rats were treated by oral gavage with Cd (50 mg/kg body wt.) once a week for 15, 30 and 60 days and sacrificed a day after last administration. After the 15th and 30th day of treatment, Cd had no effect on thiobarbituric acid reactive substances (TBARS) and endogenous Fe levels but exhibited anti-androgenic effects (p < 0.05) and caused histological damages...

Mast cells and eosinophils are increased in oral squamous cell carcinoma. The significance of such an association has been variably thought to be either a potential diagnostic tool for stromal invasion or as a prognostic indicator. The aim of the study was to study the mast cells and eosinophils between normal oral mucosa, leukoplakia and oral squamous cell carcinoma and to study the significance of mast cells in the progression of the lesion. A retrospective study was done on archival tissue received from January 2015 to December 2015, in the Department of Oral Pathology, RUHS College of Dental Sciences, Jaipur, Rajasthan, India...

Recent developments in High-Throughput DNA sequencing (HTS) technologies and ancient DNA (aDNA) research have opened access to the characterization of the microbial communities within past populations. Most studies have, however, relied on the analysis of dental calculus as one particular material type particularly prone to the molecular preservation of ancient microbial biofilms and potential of entire teeth for microbial characterization, both of healthy communities and pathogens in ancient individuals, remains overlooked...

Lead (Pb)-induced reproductive toxicity is a well-characterized adverse effect associated with this heavy metal. It has been found that Pb exposure is associated with altered spermatogenesis, increased testicular degeneration, and pathological sperm alterations. On the other hand, it has been reported that Pb-induced reproductive toxicity is associated with increased reactive oxygen species (ROS) formation and diminished antioxidant capacity in the reproductive system. Hence, administration of antioxidants as protective agents might be of value against Pb-induced reproductive toxicity...

BACKGROUND: Internal derangement is the clinical and pathological condition of disc displacement of the temporomandibular joint. Management of these cases involve conservative and surgical treatment options. Minimally invasive surgical procedures namely arthrocentesis and arthroscopy are promising techniques in the management of internal derangement. However patient selection algorithms, indications for minimally invasive procedures and details of the techniques should be further studied for safe and cost effective management of these cases...

Cardiovascular disease is currently not adequately managed and has become one of the main causes of morbidity and mortality worldwide. Current therapies are inadequate in terms of preventing its progression. There are several limitations, such as poor oral bioavailability, side effects, low adherence to treatment, and high dosage frequency of formulations due to the short half-life of the active ingredients used, among others. This review aims to highlight the most relevant aspects of the relationship between the cardiovascular system and the endocannabinoid system, with special attention to the possible translational effect of the use of anandamide in cardiovascular health...

Chronic gut inflammation disposes to an increased risk of colitis-associated cancer (CAC). Chemoprevention is an attractive complementary strategy. We aimed to evaluate the chemopreventive effects of M10, a novel derivative of Myricetin, in the murine azoxymethane (AOM)/dextran sodium sulfate (DSS) model. Oral administration of M10 at 50-100 mg/kg once a day for consecutive 12 weeks significantly prevented ulcerative colitis and colorectal tumor. Pathological analysis of intestines showed that M10 reduced the degree of chronic inflammation and prevented the progression of colorectal tumorigenesis...

In chronic periodontitis and peri-implantitis, cells of the innate and adaptive immune systems are involved directly in the lesions within the tissues of the patient. Absence of a periodontal ligament around implants does not prevent a biologic process similar to that of periodontitis from affecting osseointegration. Our first focus is on factors in the biology of individuals that are responsible for the susceptibility of such individuals to chronic periodontitis and to peri-implantitis. Genetic factors are of significant importance in susceptibility to these diseases...

Fixed drug eruption (FDE) is a drug reaction involving skin and less commonly mucosal membranes. The common manifestation is localized well-demarcated patches or plaques appeared following receiving of a culprit drug. When re-exposure occurs, the rashes will appear at areas involved in previous episodes. Limited reports on bullous FDE due to ibuprofen have been documented before. Herein, we described an elderly man who experienced multifocal lesions in his oral mucosa, penis, and multiple sites of skin following ibuprofen ingestion confirmed as FDE by pathological studies...

Parkinson's disease (PD) involves aggregation of α-synuclein and progressive loss of dopaminergic neurons. Pathogenesis of PD may also be related to one's genetic background. PD is most common among geriatric population and approximately 1-2% of population suffers over age 65 years. Currently no successful therapies are in practice for the management of PD and available therapies tend to decrease the symptoms of PD only. Furthermore, these are associated with diverse range of adverse effects profile. The neuroprotective effects of polyphenols are widely studied and documented...

Reactive lesion formation around dental implants a complication that has been given much consideration. These lesions can lead to marginal bone loss, and consequently, implant failure. In the present systematic review, all reported reactive lesions associated with dental implants in the literature were assessed. An electronic search was performed using PubMed Central, Scopus, Google Scholar, and Science Direct. The search strategy was limited to human studies (case reports and case series), full-text English language articles, published until May 2017...
