Cloning of Casuarina equisetifolia chloroplast ribosomal RNA (rRNA) genes and its application in phylogenetic studies

Chloroplast genes are considered to be highly conserved compared to the nuclear counterparts. This feature has been used extensively in the phylogenic studies of different plant species. In this study, a 3kb sequence consists of 23S rRNA (ribosomal RNA), 4.5SrRNA, ITS 2 (Intergenic Transcribed Spacer 2) and ITS 3 from the chloroplast genome of C. equisetifolia has been amplified using specific primers. The genomic origin of the PCR Amplicon was confirmed by southern hybridization. Multiple alignment with a number of chloroplast sequences showed very high homology with some of the species grouped alongwith Casuarinaceae in the phylogenetic system of classification. In the analysis, C. equisetifolia found to be grouped among the tree species which are closely placed in the classificatory system

A review of breast cancer awareness among women in India: Cancer literate or awareness deficit?

BACKGROUND: Breast cancer is the most common female cancer worldwide including India, where advanced stages at diagnosis, and rising incidence and mortality rates, make it essential to understand cancer literacy in women. We conducted a literature review to evaluate the awareness levels of risk factors for breast cancer among Indian women and health professionals. METHODS: A structured literature search using combined keywords was undertaken on bibliographic databases including MEDLINE, Cochrane Database of Systematic Reviews, Cumulative Index to Nursing and Allied Health (CINAHL) and SCOPUS. Searches were restricted to research published in English language peer-reviewed journals through December, 2014 in India. RESULTS: A total of 7066 women aged 15-70 years showed varied levels of awareness on risk factors such as family history (13-58%), reproductive history (1-88%) and obesity (11-51%). Literacy levels on risk factors did not improve over the 8-year period (2005-2013). On average, nurses reported higher, though still varied, awareness levels for risk factors such as family history (40.8-98%), reproductive history (21-90%) and obesity (34-6%). Awareness levels were not consistently higher for the stronger determinants of risk. CONCLUSION: Our review revealed low cancer literacy of breast cancer risk factors among Indian women, irrespective of their socio-economic and educational background. There is an urgent need for nation- and state-wide awareness programmes, engaging multiple stakeholders of society and the health system, to help improve cancer literacy in India

Analysis of genetic variation in different banana (Musa species) variety using random amplified polymorphic DNAs (RAPDs)

The banana (Musa acuminata Colla) is considered as an important crop plant due to its high economic value as good dietary source. Here, we analyze the genetic relationship of four different banana varieties that are cultivated in south India. Random amplified polymorphic DNAs (RAPDs) fingerprinting of these banana varieties (Grand Naine, Red Banana, Nendran and Rasthali) carried out by three primers (OPA-19, OPB-18, OPD-16) led to DNA amplification. 43.47% of the amplification products weremonomorphic (common to all the genotypes), whereas 30.43% were unique, but only 26.08% revealed the relationship between these genotypes

The Importance of Hormesis to Public Health

BACKGROUND: Hormesis is a specific type of nonmonotonic dose response whose occurrence has been documented across a broad range of biological models, diverse types of exposure, and a variety of outcomes. The effects that occur at various points along this curve can be interpreted as beneficial or detrimental, depending on the biological or ecologic context in which they occur. OBJECTIVE: Because hormesis appears to be a relatively common phenomenon that has not yet been incorporated into regulatory practice, the objective of this commentary is to explore some of its more obvious public health and risk assessment implications, with particular reference to issues raised recently within this journal by other authors. DISCUSSION: Hormesis appears to be more common than dose–response curves that are currently used in the risk assessment process [e.g., linear no-threshold (LNT)]. Although a number of mechanisms have been identified that explain many hormetic dose–response relationships, better understanding of this phenomenon will likely lead to different strategies not only for the prevention and treatment of disease but also for the promotion of improved public health as it relates to both specific and more holistic health outcomes. CONCLUSIONS: We believe that ignoring hormesis is poor policy because it ignores knowledge that could be used to improve public health

Skeletal muscle microalterations in patients carrying Malignant Hyperthermia-related mutations of the e-c coupling machinery

We have compared the ultrastructure of skeletal muscle biopsies from patients that have survived a [Malignant Hyperthermia, MH] episode and siblings that test positive for MH susceptibility with those from siblings that tested negatives. The aim is to establish whether life long exposure to the MH-related mutation effects may result in subtle abnormalities even in the absence of active episodes and/or clinically detectable deficiencies. Although a specific ultrastructural signature for MH mutants cannot be demonstrated, an MH related pattern of minor alterations does exist. These include the tendency for micro damage to the contractile apparatus and a higher than normal level of mitochondrial abnormalities

Awareness, Practices and Treatment Seeking Behavior of Type 2 Diabetes Mellitus Patients in Delhi

Background: Type 2 diabetes mellitus is a multisystem disorder that is associated with number of complications. Patient’s awareness and practices are crucial components in reducing the burden of diseases and its complications.Aim: To assess patient’s knowledge about their disease and its complications, practices, treatment seeking behavior and average expenditure incurred by its management.Subjects and Methods: A community based cross‑sectional study was conducted in rural and urban slum areas of Delhi selecting a total of 98 diabetic patients diagnosed during the two community surveys and interviewed using pretested and predesigned questionnaire. Data were analyzed using SPSS software, version 17 (Chicago II, USA). Chi‑square, fisher or Mann–Whitney tests were used for test of significance and considered statistically significant at P < 0.05.Results: Of 98 participants, 31.6% (31/98) were from urban slum area, and 68.4% (67/98) were from the rural area. In both urban and rural areas, majority were Hindu, married, literate and unemployed. Significantly less subjects (61.3%, 19/31) of urban slum area than of rural area (85.1%, 57/67) could name at least one complication of DM (P < 0.01, odds ratio [OR] =3.6, 95% confidence interval [CI] =1.3–9.6). Majority of participants in both urban slum and rural area have knowledge about at least one component of management but significantly lesser in urban (83.9%, 26/31) than rural area (97.0%, 65/67) were reported (P = 0.02, OR = 6.2, 95% CI = 1.1–34.2). Significantly more subjects (29.0%, 9/31) in urban slum area than rural areas (7.5%, 5/67) reported that they were not taking any treatment for DM (P < 0.01, OR = 0.2, 95% CI = 0.1–0.6). In urban area, 32.2% (10/31) patients told that it is a burden on their family while in rural area 44.7% (30/67) of the patients told that they have to squeeze money from the family expenditure to afford drugs.Conclusion: Patients need to be made aware of the asymptomatic phase of DM and its long‑term complications. At the same time, efforts should be made to sensitize them about the importance of taking regular treatment and management.Keywords: Diabetic mellitus type 2, Economic impact, Knowledge, Practice
