BACKGROUND: There is overwhelming evidence that periodontal disease and dental caries affect the majority of populations and that western culture and lifestyle may have a profound influence on oral health, especially in adults. The present study was performed to determine the effect of westernization on the oral health of college students of Udaipur City, Rajasthan. METHODS: A descriptive cross-sectional study was conducted among students attending various professional and non-professional bachelor's degree colleges of Udaipur City, Rajasthan, India, from March 2013 to May 2013. Eight hundred students were selected based on a two-stage random sampling procedure. Westernization was assessed by a …

The deposition of amyloid β-peptides (Aβ), cleavage products of the amyloid precursor protein (APP) by β- and γ-secretases, in brain represents a pathological hallmark of Alzheimer's disease (AD). Apolipoprotein E (APOE) ε4 allele carriers have an increased risk to develop AD and an earlier age of onset, whereas carriers of the ε2 allele have reduced risk and a delayed age of onset. APOE is also a major determinant of brain Aβ and amyloid burden in humans and in several transgenic mouse models of AD (E4>E3>E2). We have previously reported that lentivirus-mediated intraparenchymal gene delivery of APOE2 significantly reduces …

Extracellular signal-regulated kinases (ERKs) 1, 2, and 5 have been shown to play distinct roles in proliferation, differentiation, and neuronal viability. In this study, we examined ERK1, 2, and 5 expression and activation in the substantia nigra (SN), striatum (STR), and ventral tegmental area (VTA) during aging. An age-related decrease in phosphorylated ERK5 was observed in the SN and STR, whereas an increase in total ERK1 was observed in all 3 regions. In primary cultures of the SN and VTA, inhibition of ERK5 but not ERK1 and 2 decreased dopamine neuronal viability significantly. These data suggest that ERK5 is essential …

BACKGROUND: Raloxifene, a second-generation selective estrogen receptor modulator (SERM) used to prevent osteoporosis in postmenopausal women is administered orally in the form of a tablet. The absolute bioavailability of the drug is only 2% because of extensive hepatic first-pass metabolism. Lipid-based formulations are reported to reduce the first-pass metabolism by promoting its lymphatic uptake. MATERIALS AND METHODS: In the present investigation, microemulsion and Self-Microemulsifying Drug Delivery System (SMEDDS) formulations of Raloxifene were prepared. The prepared formulations were characterized for drug loading, size, transparency, zeta potential, Transmission Electron Microscopy (TEM) and in vitro intestinal permeability. RESULTS: The results indicated that high …

Decades of intense research has shown that hyperglycemiainduced ROS production can lead to a redox-imbalance causing oxidative stress (OS) in a variety of target organs in vivo. In the absence of an efficient antioxidant counteracting system, massive OS often leads to activation of stress-responsive signaling pathways resulting in deregulated expression of pro-survival and/or pro-death genes. Persistent deregulation of such pathways eventually masterminds late complications of diabetes. Most studies hold hyperglycemia-induced OS as the ‘cause’, and premature onset of apoptosis as the ‘effect’. This ‘cause and effect’ axis ultimately initiates the development and progression of macro and microvascular complications including diabetic …
