Abstract
An essential prerequisite to safeguard pollinator species is characterisation of the multifaceted diversity of crop pollinators and identification of the drivers of pollinator community changes across biogeographical gradients. The extent to which intensive agriculture is associated with the homogenisation of biological communities at large spatial scales remains poorly understood. In this study, we investigated diversity drivers for 644 bee species/morphospecies in 177 commercial apple orchards across 33 countries and four global biogeographical biomes. Our findings reveal significant taxonomic dissimilarity among biogeographical zones. Interestingly, despite this dissimilarity, species from different zones share similar higher-level phylogenetic groups and similar ecological and behavioural traits (i.e. functional traits), likely due to habitat filtering caused by perennial monoculture systems managed intensively for crop production. Honey bee species dominated orchard communities, while other managed/manageable and wild species were collected in lower numbers. Moreover, the presence of herbaceous, uncultivated open areas and organic management practices were associated with increased wild bee diversity. Overall, our study sheds light on the importance of large-scale analyses contributing to the emerging fields of functional and phylogenetic diversity, which can be related to ecosystem function to promote biodiversity as a key asset in agroecosystems in the face of global change pressures.

Abstract
Human papillomaviruses (HPV)-related gynecological cancers are a major health care issue, and a leading cause of cancer death in low- and middle-income countries (LMIC). In 2020, the World Health Organization launched a program aimed at cervical cancer elimination, by screening and vaccination strategies. Offering the best possible care to women diagnosed with invasive cancer is a complementary objective. Treatment of cervical cancer as per modern standards is complex and multimodal, mainly relying on surgery, external-beam radiotherapy (+/-chemotherapy) and brachytherapy. In parallel with the pivotal role of multidisciplinary discussion, international societies provide guidance to define the most effective and least toxic anti-cancer strategy, homogenize treatment protocols and provide benchmark quality indicators as a basis for accreditation processes. The challenge is to offer the appropriate diagnostic workup and treatment upfront and to avoid non- evidence-based treatment that consumes resources, impairs quality of life (QoL), and compromises oncological outcome. Various strategies may be applied for improving treatment quality: development of surgical mentorship, companion-training programs and international cooperation. The lack of radiotherapy/brachytherapy facilities is a major concern in LMIC. Reinforcing international support in terms of education, training, research and development and technical cooperation with national projects is required to increase access to minimum requirements but also introduce modern techniques, upgrade radiotherapy/brachytherapy services, and expand access to modern systemic treatments. In countries with robust economies, compliance to standards should also be increased. Integrative cancer care and multidisciplinary approaches are needed to tackle the dual challenge of increasing cure rates while minimizing QoL impairment. Appropriate dimensioning of the resources to avoid harmful treatment delays and access to expert referral centers is also a priority.

Abstract
PURPOSE To identify key factors for the best practice of knowledge transfer from high-income settings to low- and middle-income settings. RESULTS Interactive sessions led to the identification of European learnings that can and should be shared beyond Europe. Furthermore, methods were characterised which may lead to successful knowledge transfer with subsequent quality improvement. CONCLUSION To ensure successful implementation of knowledge and new methods, political support is extremely important. A strong focus should be an improvement of collaboration and network development. Rehabilitation, early and late pallative care, cost effectiveness and long-term follow-up are priorities. Limitations are budget constraints which limit the execution of NCCPs.

Abstract
Background: Success of a cervical cancer screening program is intrinsically linked with appropriate management of women detected positive on screening tests. While routine screening can be done in any setting, the follow-up care of screen positive women is linked with settings that are equipped with diagnostic and treatment facilities, and trained medical providers. In low resource settings, the major obstacles to deliver follow-up care are lack of adequate healthcare infrastructure and trained service providers at district or subdistrict levels. Aim: To assess feasibility of implementing community based interventions to increase uptake of follow-up care of screen positive women in a HPV detection based screening program conducted by Chittaranjan National Cancer Institute (CNCI), Kolkata. Strategy: A network of key stakeholders including government authorities and civil society organizations was developed to deliver continuum of care at the doorsteps of screen positive women. The infrastructure of government's primary health care delivery system was used to set up temporary clinics at district and subdistrict levels. The clinics were organized on prescheduled dates and times that were convenient to the women. Community health workers (CHWs) were trained in community mobilization strategies to increase uptake of follow-up services. All instruments, equipment and consumables required for providing follow-up services were carried to the clinics in a vehicle. Program: The CHWs played a key role in counseling and recalling the screen positive women. The temporary clinics were arranged in the government primary health centers. A team of trained doctors and paramedics provided the diagnostic and treatment services. Colposcopy was performed on all screen positive women using portable colposcopes and guided biopsies were taken as indicated. Women who were eligible for ablative treatment were counseled and treated in the same sitting. All women were advised yearly follow-up. Outcomes: A total of 43,325 women were screened by HC2 test during July 2010 to March 2015, and 2045 (4.7%) women were detected to be high-risk HPV positive. Compliance to first recall was good with 78.6% (1608/2045) of women undergoing diagnostic evaluation at field clinics. But overall compliance to at least one follow-up visit after 1 year was poor (23.2%). Follow-up compliance rate was higher in women who were diagnosed with CIN1 as compared with those with normal diagnosis ( P < 0.001). What was learned: Diagnostic and treatment services could be effectively organized in the community in convergence with existing healthcare delivery system. High compliance to initial diagnostic evaluation and treatment was achieved by making the services available close to the doorsteps of the women. The reasons for low compliance to yearly follow-up were lack of understanding of future cancer risk, unwilling to undergo speculum examination again, and lack of cooperation of spouse/family.

Abstract
BACKGROUND Ovarian cancer is one of the leading cancers in Indian women. The current standard of care is a combination of surgical staging, maximal surgical effort to achieve cytoreduction, and judicious use of chemotherapy. Multimodality therapy can reduce mortality, but the practice and uptake of such therapy in Indian Institutions are not up to the desired level. OBJECTIVES To study the protocol adherence for ovarian cancer management along with patient compliance and evaluate their effects on survival. MATERIALS AND METHODS The retrospective study obtained and analyzed data from records of patients operated for ovarian cancer at a Regional Cancer Center in eastern India between January 2002 and December 2006. RESULTS The records of 202 patients were evaluable. None of the patients who had primary surgery outside the institute had staging information. A substantial number of patients operated at the institute had incomplete surgical staging, inadequate information on residual disease after surgery, and incomplete histology report. Only 20.3% patients could have optimal cytoreduction after surgery. Compliance to chemotherapy was poor. The median overall survival time and disease-free survival time were 24 months and 5 months, respectively. The residual disease after surgery significantly affected the overall survival, but not the disease-free survival. Incomplete chemotherapy was found to adversely affect survival after adjusting for advanced stage and bulky residual disease. CONCLUSION Management of ovarian cancer is suboptimal even in the specialized cancer institute. Poor patient compliance to chemotherapy is one of the major factors adversely affecting survival from advanced ovarian cancer.

Abstract
Locally advanced cervical cancers comprise a large majority of the gynecologic cancers in India and other developing countries. Concurrent chemo-radiation has improved the survival of high risk stage I and stage II cervical cancers. There is no evidence that the same survival benefit has been achieved with chemo-radiation in stage III and stage IV disease. Interferon-alpha and Retinoic acid have synergistic anti-proliferative activity. In combination with radiation, they substantially enhance the sensitivity of the squamous carcinoma cells to radiation. Based on these observations from the in vitro studies, a few clinical trials have evaluated the combination of interferon-alpha and Retinoic acid, concomitant with radiation, to treat cervical cancers. The results from these early trials were encouraging and the combination had minimal toxicities. However, till date, no phase III randomized controlled trial has been done to evaluate this therapeutic modality.

Abstract
OBJECTIVES MJD1/SCA3 is the most common type of spinocerebellar ataxia (SCA) worldwide. To explain the low prevalence of the disease among SCA patients from eastern India, we analysed CAG repeats and two bi-allelic intragenic markers at SCA3 locus among 412 normal individuals and 10 patients. MATERIALS AND METHODS For CAG repeat analysis, PCR amplified fragments were run on polyacrylamide gel, transferred to a membrane, probed with (CAG)10 and detected on an autoradiograph. Bi-allelic markers were analysed using allele specific PCR amplification. RESULTS Large normal alleles (>33 CAG repeats) were 0.015 in pooled populations. All the patients had the common haplotype C-A as observed worldwide. Frequency of C-A haplotype among large normal alleles was 0.75. CONCLUSIONS Observed low prevalence of SCA3 could be because of the low prevalence of large normal alleles that might act as the reservoir for the expanded alleles. SCA3 mutation in Indian populations had the same origin as found worldwide.

Abstract
India is a high-risk country for cervical cancer which accounts a quarter (126,000 new cases, 71,000 deaths around 2,000) of the world burden. The age-standardized incidence rates range from 16-55 per 100,000 women in different regions with particularly high rates in rural areas. Control of cervical cancer by early detection and treatment is a priority of the National Cancer Control Programme of India. There are no organized cytology screening programmes in the country. The technical and financial constraints to organize cytology screening have encouraged the evaluation of visual inspection approaches as potential alternatives to cervical cytology in India. Four types of visual detection approaches for cervical neoplasia are investigated in India: a) naked eye inspection without acetic acid application, widely known as 'downstaging'; b) naked eye inspection after application of 3-5% acetic acid (VIA); c) VIA using magnification devices (VIAM); d) visual inspection after the application of Lugol's iodine (VILI). Downstaging has been shown to be poorly sensitive and specific to detect cervical neoplasia and is no longer considered as a suitable screening test for cervical cancer. VIA, VIAM and VILI are currently being investigated in multicentre cross-sectional studies (without verification bias), in which cytology and HPV testing are also simultaneously evaluated, and the results of these investigations will be available in 2003. These studies will provide valuable information on the average, comparative test performances in detecting high-grade cervical cancer precursors and cancer. Results from pooled analysis of data from two completed studies indicated an approximate sensitivity of 93.4% and specificity of 85.1% for VIA to detect CIN 2 or worse lesions; the corresponding figures for cytology were 72.1% and 91.6%. The efficacy of VIA in reducing incidence of an mortality from cervical cancer and its cost-effectiveness is currently being investigated in two cluster randomized controlled intervention trials in India. One of these studies is a 4-arm trial addressing the comparative efficacy of VIA, cytology and primary screening with HPV DNA testing. This trial will provide valuable information on comparative detection rates of CIN 2-3 lesions by the middle of 2003. The expected outcomes from the Indian studies will contribute valuable information for guiding the development of public health policies on cervical cancer prevention in countries with different levels of socio-economic and health services development and open up new avenues of research.

Abstract
Microbial activity is responsible for the transformation of at least one third of the elements in the periodic table. These transformations are the result of assimilatory, dissimilatory, or detoxification processes and form the cornerstones of many biogeochemical cycles. Arsenic and selenium are two elements whose roles in microbial ecology have only recently been recognized. Known as "essential toxins", they are required in trace amounts for growth and metabolism but are toxic at elevated concentrations. Arsenic is used as an osmolite in some marine organisms while selenium is required as selenocysteine (i.e. the twenty-first amino acid) or as a ligand to metal in some enzymes (e.g. FeNiSe hydrogenase). Arsenic resistance involves a small-molecular-weight arsenate reductase (ArsC). The use of arsenic and selenium oxyanions for energy is widespread in prokaryotes with representative organisms from the Crenarchaeota, thermophilic bacteria, low and high G+C gram-positive bacteria, and Proteobacteria. Recent studies have shown that both elements are actively cycled and play a significant role in carbon mineralization in certain environments. The occurrence of multiple mechanisms involving different enzymes for arsenic and selenium transformation indicates several different evolutionary pathways (e.g. convergence and lateral gene transfer) and underscores the environmental significance and selective impact in microbial evolution of these two elements.

Abstract
The frequencies of haplotypes based upon the (CTG)n repeat and three other biallelic markers in and around the myotonic dystrophy (DM) locus were estimated in 13 ethnically, linguistically and geographically diverse sub-populations of India. The range of CTG repeats in caste populations was 5-31, while in tribal populations the range was shorter (5-23). Extensive variation in frequencies of large (CTG)n alleles (> or =18 repeats) was found in Indian populations. The implications of this finding on DM epidemiology are discussed. Haplotype diversity was found to be very high in most populations. The majority of the Indian DM patients carried a haplotype that is commonly found among DM patients globally; this is the most common haplotype in the class of large (> or =18 repeats) CTG alleles. However, one haplotype was found to be present in particularly high frequency in Indian populations; this haplotype was also found among Indian DM patients. This haplotype may be a characteristic of Indian and possibly of other East Asian populations.

Abstract
Within the avian telencephalon, the dorsal ventricular ridge (DVR) contains higher order and multimodal integration areas. Using multiple regressions on 17 avian taxa, we show that an operational estimate of behavioral flexibility, the frequency of feeding innovation reports in ornithology journals, is most closely predicted by relative size of one of these DVR areas, the hyperstriatum ventrale. Neither phylogeny, juvenile development mode, nor species sampled account for the relationship. Similar results are found when the hyperstriatum ventrale is lumped with a second DVR structure, the neostriatum. In simple correlations, size of the wulst and the striatopallidal complex is associated with feeding innovation rate, but the two structures are eliminated from the multiple regressions. Our results parallel those on primates showing a correlation between innovation rate and neocortex size and support the idea that the mammalian neocortex and the neostriatum-hyperstriatum ventrale complex in birds have similar integrative roles.

Abstract
We have studied the CTG repeat sizes in the DMPK gene and six biallelic markers which are in complete linkage disequlibrium with Caucasian DM patients, to identify any common founder haplotype in 30 clinically diagnosed unrelated DM patients from eastern India. Our results revealed that in 27 patients (90%), CTG expansion took place on a DraIII(-) - HhaI(-) - Alu(+) - HinfI(+) - Fnu4H I(-) - TaqI(+) haplotype (haplotype I), similar to what have been published for Caucasoid and other DM patients. However, in three patients (10%), the expansion of CTG repeat was on DraIII(+) - HhaI(+) - Alu(+) - HinfI(-) - Fnu4H I(+) - TaqI(-) background (haplotype II), indicating a new haplotype. The distribution of haplotypes in 52 normal individuals of eastern India revealed that percentage of haplotypes I and II were 23.1% and 7.7% respectively in normal chromosomes. Haplotype II is absent among Caucasian DM patients as well as normal individuals indicating that this particular haplotype may be characteristic of the Indian population. Hum Mutat 16:372, 2000.

Abstract
We have analysed the distribution of CAG and adjacent polymorphic CCG repeats in the Huntingtin gene in 28 clinically diagnosed unrelated Huntington's disease (HD) patients and in normal individuals belonging to different ethnic groups of India. The range of expanded CAG repeats in HD patients varied from 41 to 56 repeats, whereas in normal individuals this number varied between 11 and 31 repeats. We identified six CCG alleles from a total of 380 normal chromosomes that were pooled across different ethnic populations of India. There were two predominant alleles: (CCG)7 (72.6%) and (CCG)10 (20%). We report here for the first time one four-repeat CCG allele which has not been found in any population so far. We found 30 haplotypes (two loci CAG-CCG) for 380 normal chromosomes. In the present study, no statistically significant preponderance of expanded HD alleles was found on either (CCG)7 or (CCG)10 backgrounds. Our studies suggest that the overall prevalence of HD in Indian populations may not be as high as in Western populations. Further studies are necessary to identify the origin of HD mutation in these populations.

Abstract
To identify various subtypes of spinocerebellar ataxias (SCAs) among 57 unrelated individuals clinically diagnosed as ataxia patients we analysed the SCA1, SCA2, SCA3, SCA6, SCA7 and DRPLA loci for expansion of CAG repeats. We detected CAG repeat expansion in 6 patients (10.5%) at the SCA1 locus. Ten of the 57 patients (17.5%) had CAG repeat expansion at the SCA2 locus, while four had CAG expansion at the SCA3/MJD locus (7%). At the SCA6 locus there was a single patient (1.8%) with 21 CAG repeats. We have not detected any patient with expansion in the SCA7 and DRPLA loci. To test whether the frequencies of the large normal alleles in SCA1, SCA2 and SCA6 loci can reflect some light on prevalence of the subtypes of SCAs we studied the CAG repeat variation in these loci in nine ethnic sub-populations of eastern India from which the patients originated. We report here that the frequency of large normal alleles (>31 CAG repeats) in SCA1 locus to be 0.211 of 394 chromosomes studied. We also report that the frequency of large normal alleles (>22 CAG repeats) at the SCA2 locus is 0.038 while at the SCA6 locus frequency of large normal alleles (>13 repeats) is 0.032. We discussed our data in light of the distribution of normal alleles and prevalence of SCAs in the Japanese and white populations.

Abstract
Nitrate reduction in the dissimilatory iron-reducing bacterium Geobacter metallireducens was investigated. Nitrate reductase and nitrite reductase activities in nitrate-grown cells were detected only in the membrane fraction. The apparent K(m )values for nitrate and nitrite were determined to be 32 and 10 microM, respectively. Growth on nitrate was not inhibited by either tungstate or molybdate at concentrations of 1 mM or less, but was inhibited by both at 10 and 20 mM. Nitrate and nitrite reductase activity in the membrane fraction was not, however, affected by dialysis with 20 mM tungstate. An enzyme complex that exhibited both nitrate and nitrite reductase activity was solubilized from membrane fractions with CHAPS and was partially purified by preparative gel electrophoresis. It was found to be composed of four different polypeptides with molecular masses of 62, 52, 36, and 16 kDa. The 62-kDa polypeptide [a low-midpoint potential (-207 mV), multiheme cytochrome c] exhibited nitrite reductase activity under denaturing conditions. No molybdenum was detected in the complex by plasma-emission mass spectrometry.

Abstract
From the historically prevalent social structure of Indian populations it may be predicted that there has been very little male gene flow across ethnic boundaries. To test this finding, we have analyzed DNA samples of individuals belonging to 10 ethnic groups, speaking Indo-European or Austroasiatic languages and inhabiting the eastern and northern regions of India. Eight Y-chromosomal markers, two biallelic and six microsatellite, were studied. All populations were monomorphic for the deletion allele at the YAP (DYS287) locus and for the 119-bp allele at the DYS288 locus. Y-chromosomal haplotypes were constructed on the basis of one RFLP locus and five microsatellite loci. The haplotype distribution among the groups showed that different ethnic groups harbor nearly disjoint sets of haplotypes. This indicates that there has been virtually no male gene flow among ethnic groups. Analysis of molecular variance revealed that there was significant haplotypic variation between castes and tribes, but nonsignificant variation among ranked caste clusters. Haplotypic variation attributable to differences in geographical regions of habitat was also nonsignificant.
