Nitrogen heterocyclic compounds such as pyrazolines have been found to possess a broad spectrum of biological activities such as anticancer, antitubercular, anti-inflammatory, analgesic, and antidepressant activities. Pyrazoline derivatives IV, V (a-e) have been synthesized from the intermediate chalcones III (a-h) by cyclizing with phenyl hydrazine and hydrazine hydrate. The structures of these compounds were confirmed by IR, NMR, and mass spectroscopy. Biological studies of the synthesized compounds showed promising antitumor, analgesic, and anti-inflammatory activities. The compounds were tested for their in vitro antitumor activity against EAC tumor cell lines. Compounds IVa and IVb showed the highest cytotoxicity of 80% at a 200g mL concentration. Among the tested compounds, IVa and Vd seem to be more effective analgesic agents. Compounds IVc, IVd, and Ve are found to be the most effective anti-inflammatory agents. Thus the results show that synthesized compounds possess antitumor, analgesic, and anti-inflammatory activity. It was observed that the test compounds with electron withdrawing groups (halogens) on the aromatic ring favors antitumor, analgesic, and anti-inflammatory activity.

Ageing is associated with changes in cardiac autonomic control as measured by Heart Rate Variability (HRV). Not many studies have explored the influence of gender on age-related changes in cardiac autonomic regulation. This study evaluated the gender differences in age-associated changes in cardiac autonomic nervous activity by assessing HRV using frequency domain analysis of short-term stationary R-R intervals. HRV was studied in healthy males and females ranging in age from 6 to 55 years. Total power and absolute power in High-Frequency (HF) and Low-Frequency (LF) components as well as HF in normalized unit declined significantly with ageing. The HF/LF ratio was significantly higher in the adolescent and adult females compared to male of these age groups. This study suggests that gender differences exist in age-related changes in HRV. The finding that gender differences are limited to adolescent and adult age groups may indicate a role for female sex hormones in cardiac autonomic modulation. © 2012 Shailaja Moodithaya and Sandhya T.

A significant fraction of the human genome is transcribed as non-coding RNAs (ncRNAs). This non-coding transcriptome has challenged the notion of the central dogma and its involvement in transcriptional and post-transcriptional regulation of gene expression is well established. Interestingly, several ncRNAs are dysregulated in cancer and current non-coding transcriptome research aims to use our increasing knowledge of these ncRNAs for the development of cancer biomarkers and anti-cancer drugs. In endocrine-related cancers, for which survival rates can be relatively low, there is a need for such advancements. In this review, we aimed to summarize the roles and clinical implications of recently discovered ncRNAs, including long ncRNAs, PIWI-interacting RNAs, tRNA- and Y RNA-derived ncRNAs, and small nucleolar RNAs, in endocrine-related cancers affecting both sexes. We focus on recent studies highlighting discoveries in ncRNA biology and expression in cancer, and conclude with a discussion on the challenges and future directions, including clinical application. ncRNAs show great promise as diagnostic tools and therapeutic targets, but further work is necessary to realize the potential of these unconventional transcripts. © 2015 Elsevier Ireland Ltd.

Human papilloma virus (HPV) is one of the most common virus groups affecting the skin and mucosal areas of the body in the world today. It is also a known fact that HPV causes many lesions in the oral cavity. The most common conditions induced by oral HPV infection are usually benign-like oral papillomas, oral condylomas, and focal epithelial hyperplasia. Oral HPV infection has been found to be associated with some cases of oropharyngeal cancer, but it is not the main risk factor for this kind of cancer. HPV is been proved to be the causative agent in causation of cervical cancers without doubt, but its role as a etiologic agent in causing oral cancers needs to be evaluated and studied more to come into any conclusion. We have used review papers, case reports, cohort studies, case control studies, and various internet sources published from 1960 to 2011 to prepare this review of literature.

ZIKV infection has become a global threat spreading across 31 countries in Central America, South America, and the Caribbean. However, little information is available about the molecular epidemiology of ZIKV. Shared mutation of a threonine residue to alanine at the same position in the C terminal of NS5 sequences was observed in sequences from Colombia, Mexico, Panama, and Martinique. The sequences in the phylogenetic tree fell within the same cluster. Based on shared mutation the presence of a Latin American genotype was proposed. Comparison of African and Asian lineages yielded R29N, N273S, H383Q, and P391S mutation. The study highlights that mutation of amino acids at NS5 may contribute to neutropism of ZIKV. J. Med.

There is a dearth of epidemiological data about multiple sclerosis (MS) and related demyelinating disorders in India. In this study, a registry method was used for collecting data from secure sources and the index cases were verified Seventy nine patients were identified. A crude prevalence of 8.3/100,000 was obtained for MS and 6.2/100,000 for clinically-isolated syndrome (CIS). Age-standardized prevalence of MS relative to the world population was 7.8/100,000. Neuromyelitis optica (NMO) and spectrum disorders (NMOS) constituted 13.9% of all demyelinating disorders, with a prevalence of 2.6/100,000. Larger studies with more refined survey methodologies are required to understand the true prevalence of demyelinating disorders in India. © The Author(s) 2014.

Purpose: To evaluate the effectiveness of systemic enzyme therapy for the control of edema in patients who undergo bimaxillary orthognathic surgery. Materials and Methods: Thirty patients were included in this double-blinded, randomized, control trial. Before surgery, each patient was allotted a code (study or control group). Nine anthropometric points were selected. Thickness of the soft tissue at each of these points was measured using an ultrasound device. These measurements were performed on the day before surgery and 1, 5, and 15 days after surgery. The study group was given a twice-daily dose of systemic enzyme therapy from the first postoperative day for 5 days; the control group was given placebo. The percentage of difference in the thickness of the soft tissue was calculated at each of the 9 points on postoperative days 1, 5, and 15. These data were analyzed and compared using the Mann-Whitney test. Results: The statistical evaluation showed a significant difference in soft tissue thickness between the 2 groups, especially on days 5 and 15, at most assessed points. Conclusion: The results of this study suggest that systemic enzyme therapy significantly decreases postoperative edema in orthognathic surgery, precluding long-term corticosteroid use. © 2013 American Association of Oral and Maxillofacial Surgeons.

Multiple Sclerosis (MS) is being diagnosed in increasing numbers in metropolitan cities of India for which the availability of specialist neurologists and magnetic resonance imaging (MRI) facilities are primarily responsible. Epidemiological data are unavailable. Existing data have been obtained from small often retrospective studies from different parts of the country. These earlier studies suggested that optic nerve and spinal cord involvement are considerably high, and that perhaps optic spinal MS was the most prevalent form in India. On this basis it was also speculated that neuromyelitis optica (NMO) may be overrepresented in Indians. However in recent times, prospective studies backed by MRI data have shown no distinct differences between MS seen in the west and India. Sero positivity for NMO IgG is low though NMO phenotype disorders constitute nearly 20 of demyelinating disorders in India. Genetic susceptibility for MS among Indians may be similar to that for white populations. In the major histocompatibility complex (MHC), HLA DR11501 has been strongly associated with MS in Indians. A recent study that evaluated the established non-MHC multiple sclerosis loci in a small data set of Indian patients suggested a strong similarity with white populations. This review highlights some of the background information available on MS from India and so also some recent studies that unveiled the disease characteristics in Indian patients. © 2011 Lekha Pandit.

Amelogenesis imperfecta encompasses a group of inherited abnormalities that are generally considered to primarily affect the formation and/or calcification of enamel. This case report describes the unusual presentation of amelogenesis imperfecta in siblings as multiple unerupted teeth, multiple pulpal calcifications, and multiple dilacerations of roots along with the defect in the enamel. The intent of our report is to highlight a rare co-occurrence of amelogenesis imperfecta with multiple morphologic alterations in siblings.

Ribosomal RNAs are the most abundant and universal noncoding RNAs in living organisms. In eukaryotes, three of the four ribosomal RNAs forming the 40S and 60S subunits are borne by a long polycistronic pre-ribosomal RNA. A complex sequence of processing steps is required to gradually release the mature RNAs from this precursor, concomitant with the assembly of the 79 ribosomal proteins. A large set of trans-acting factors chaperone this process, including small nucleolar ribonucleoparticles. While yeast has been the gold standard for studying the molecular basis of this process, recent technical advances have allowed to further define the mechanisms of ribosome biogenesis in animals and plants. This renewed interest for a long-lasting question has been fueled by the association of several genetic diseases with mutations in genes encoding both ribosomal proteins and ribosome biogenesis factors, and by the perspective of new anticancer treatments targeting the mechanisms of ribosome synthesis. A consensus scheme of pre-ribosomal RNA maturation is emerging from studies in various kinds of eukaryotic organisms. However, major differences between mammalian and yeast pre-ribosomal RNA processing have recently come to light. © 2014 The Authors. WIREs RNA published by John Wiley & Sons, Ltd.
