Genetic population structure of the malaria vector Anopheles baimaii in north-east India using mitochondrial DNA

<p>Abstract</p> <p>Background</p> <p><it>Anopheles baimaii </it>is a primary vector of human malaria in the forest settings of Southeast Asia including the north-eastern region of India. Here, the genetic population structure and the basic population genetic parameters of <it>An. baimaii </it>in north-east India were estimated using DNA sequences of the mitochondrial cytochrome oxidase sub unit II (COII) gene.</p> <p>Methods</p> <p><it>Anopheles baimaii </it>were collected from 26 geo-referenced locations across the seven north-east Indian states and the COII gene was sequenced from 176 individuals across these sites. Fifty-seven COII sequences of <it>An. baimaii </it>from six locations in Bangladesh, Myanmar and Thailand from a previous study were added to this dataset. Altogether, 233 sequences were grouped into eight population groups, to facilitate analyses of genetic diversity, population structure and population history.</p> <p>Results</p> <p>A star-shaped median joining haplotype network, unimodal mismatch distribution and significantly negative neutrality tests indicated population expansion in <it>An. baimaii </it>with the start of expansion estimated to be ~0.243 million years before present (MYBP) in north-east India. The populations of <it>An. baimaii </it>from north-east India had the highest haplotype and nucleotide diversity with all other populations having a subset of this diversity, likely as the result of range expansion from north-east India. The north-east Indian populations were genetically distinct from those in Bangladesh, Myanmar and Thailand, indicating that mountains, such as the Arakan mountain range between north-east India and Myanmar, are a significant barrier to gene flow. Within north-east India, there was no genetic differentiation among populations with the exception of the Central 2 population in the Barail hills area that was significantly differentiated from other populations.</p> <p>Conclusions</p> <p>The high genetic distinctiveness of the Central 2 population in the Barail hills area of the north-east India should be confirmed and its epidemiological significance further investigated. The lack of genetic population structure in the other north-east Indian populations likely reflects large population sizes of <it>An. baimaii </it>that, historically, were able to disperse through continuous forest habitats in the north-east India. Additional markers and analytical approaches are required to determine if recent deforestation is now preventing ongoing gene flow. Until such information is acquired, <it>An. baimaii </it>in north-east India should be treated as a single unit for the implementation of vector control measures.</p

Horizontal acquisition of multiple mitochondrial genes from a parasitic plant followed by gene conversion with host mitochondrial genes

Background: Horizontal gene transfer (HGT) is relatively common in plant mitochondrial genomes but the mechanisms, extent and consequences of transfer remain largely unknown. Previous results indicate that parasitic plants are often involved as either transfer donors or recipients, suggesting that direct contact between parasite and host facilitates genetic transfer among plants. Results: In order to uncover the mechanistic details of plant-to-plant HGT, the extent and evolutionary fate of transfer was investigated between two groups: the parasitic genus Cuscuta and a small clade of Plantago species. A broad polymerase chain reaction (PCR) survey of mitochondrial genes revealed that at least three genes (atp1, atp6 and matR) were recently transferred from Cuscuta to Plantago. Quantitative PCR assays show that these three genes have a mitochondrial location in the one species line of Plantago examined. Patterns of sequence evolution suggest that these foreign genes degraded into pseudogenes shortly after transfer and reverse transcription (RT)- PCR analyses demonstrate that none are detectably transcribed. Three cases of gene conversion were detected between native and foreign copies of the atp1 gene. The identical phylogenetic distribution of the three foreign genes within Plantago and the retention of cytidines at ancestral positions of RNA editing indicate that these genes were probably acquired via a single, DNA-mediated transfer event. However, samplings of multiple individuals from two of the three species in the recipient Plantago clade revealed complex and perplexing phylogenetic discrepancies and patterns of sequence divergence for all three of the foreign genes. Conclusions: This study reports the best evidence to date that multiple mitochondrial genes can be transferred via a single HGT event and that transfer occurred via a strictly DNA-level intermediate. The discovery of gene conversion between co-resident foreign and native mitochondrial copies suggests that transferred genes may be evolutionarily important in generating mitochondrial genetic diversity. Finally, the complex relationships within each lineage of transferred genes imply a surprisingly complicated history of these genes in Plantago subsequent to their acquisition via HGT and this history probably involves some combination of additional transfers (including intracellular transfer), gene duplication, differential loss and mutation-rate variation. Unravelling this history will probably require sequencing multiple mitochondrial and nuclear genomes from Plantago

Familial hypercholesterolaemia in children and adolescents from 48 countries: a cross-sectional study

Background: Approximately 450 000 children are born with familial hypercholesterolaemia worldwide every year, yet only 2·1% of adults with familial hypercholesterolaemia were diagnosed before age 18 years via current diagnostic approaches, which are derived from observations in adults. We aimed to characterise children and adolescents with heterozygous familial hypercholesterolaemia (HeFH) and understand current approaches to the identification and management of familial hypercholesterolaemia to inform future public health strategies. Methods: For this cross-sectional study, we assessed children and adolescents younger than 18 years with a clinical or genetic diagnosis of HeFH at the time of entry into the Familial Hypercholesterolaemia Studies Collaboration (FHSC) registry between Oct 1, 2015, and Jan 31, 2021. Data in the registry were collected from 55 regional or national registries in 48 countries. Diagnoses relying on self-reported history of familial hypercholesterolaemia and suspected secondary hypercholesterolaemia were excluded from the registry; people with untreated LDL cholesterol (LDL-C) of at least 13·0 mmol/L were excluded from this study. Data were assessed overall and by WHO region, World Bank country income status, age, diagnostic criteria, and index-case status. The main outcome of this study was to assess current identification and management of children and adolescents with familial hypercholesterolaemia. Findings: Of 63 093 individuals in the FHSC registry, 11 848 (18·8%) were children or adolescents younger than 18 years with HeFH and were included in this study; 5756 (50·2%) of 11 476 included individuals were female and 5720 (49·8%) were male. Sex data were missing for 372 (3·1%) of 11 848 individuals. Median age at registry entry was 9·6 years (IQR 5·8-13·2). 10 099 (89·9%) of 11 235 included individuals had a final genetically confirmed diagnosis of familial hypercholesterolaemia and 1136 (10·1%) had a clinical diagnosis. Genetically confirmed diagnosis data or clinical diagnosis data were missing for 613 (5·2%) of 11 848 individuals. Genetic diagnosis was more common in children and adolescents from high-income countries (9427 [92·4%] of 10 202) than in children and adolescents from non-high-income countries (199 [48·0%] of 415). 3414 (31·6%) of 10 804 children or adolescents were index cases. Familial-hypercholesterolaemia-related physical signs, cardiovascular risk factors, and cardiovascular disease were uncommon, but were more common in non-high-income countries. 7557 (72·4%) of 10 428 included children or adolescents were not taking lipid-lowering medication (LLM) and had a median LDL-C of 5·00 mmol/L (IQR 4·05-6·08). Compared with genetic diagnosis, the use of unadapted clinical criteria intended for use in adults and reliant on more extreme phenotypes could result in 50-75% of children and adolescents with familial hypercholesterolaemia not being identified. Interpretation: Clinical characteristics observed in adults with familial hypercholesterolaemia are uncommon in children and adolescents with familial hypercholesterolaemia, hence detection in this age group relies on measurement of LDL-C and genetic confirmation. Where genetic testing is unavailable, increased availability and use of LDL-C measurements in the first few years of life could help reduce the current gap between prevalence and detection, enabling increased use of combination LLM to reach recommended LDL-C targets early in life

Not AvailableTrypanosoma evansi is a haemo-protozoan parasite responsible for the disease surra, an economically important disease of wide range of domestic and wild animals. The present diagnostic methods using soluble antigens have inherent problems like lack of standardized and reproducible antigens, as well as ethical issues. This entails further efforts for search of defined antigenic molecules with satisfying sensitivity and specificity for sero-epidemiology of trypanosomosis. In present investigation, we have identified and purified 52-55kDa immuno-dominant protein cluster in molecular mass ranges by preparatory SDS-PAGE methods from T. evansi proteome. The purified protein was further characterized by hyper immune serum raised in rabbits and also further evaluated for its immunodiagnostic potential using experimentally infected horse serum samples by different immunological tests. The immunoblot, ELISA and dot blot assay using purified cluster in infected pooled serum samples showed detection of infection early as 10th days post infection till termination of experiment. The observations revealed that purified cluster is expressed not only at early stage but also persisted and detected throughout course of infection. Further, whole cell lysate antigen separated out and detected 141 spots by 2-D gel electrophoresis. The isoelectric focussing (PI) of 52-55kDa was determined in pH range between 6.9 and 7.5 along with two other cluster of proteins recognised by immune sera of ponies infected with T. evansi. MS/MS analysis of the purified protein cluster identified five proteins i.e. pyruvate kinase 1, beta tubulin, paraflagellar rod protein, alanine aminotransferase and variable surface glycoprotein showing homology to protein present in Trypanosome database. These identified proteins may be useful for development of vaccines and diagnostic targets against animal trypanosomosis.Not Availabl

Prognostic Value of Microscopic Linear Length and Gleason Score of the Tumor at Positive Margin in Robot Assisted Radical Prostatectomy Specimens: A Study of 127 Whole Mount Cases

Background: Localized prostate cancers (PCa) are usually treated with radical prostatectomy (RP) to improve cancer specific survival. Presence of positive surgical margins (PSM) is an independent prognostic factor as well as a reason for adjuvant therapy. Currently there is heterogeneous data about the significance of extent of PSM. Some studies have used the term focal and extensive and others have done exact quantification of the PSM. Some studies have questioned if extent of positive surgical margin provides any additional prognostic significance. On this background, we wanted to assess the correlation of linear length of PSM in RP specimens with the risk of biochemical recurrence (BCR). In addition, we also evaluated other pathologic parameters such as Gleason score (GS) of the tumor at the positive margin, location of positive margin, and positivity within or outside of the prostatic capsule. Design: We reviewed 127 cases of PCa with PSM on patients who underwent RP at our institution between 2012-2014. Microscopic linear length (LL) of positive margin was measured and cases were stratified as follows, LL3mm. Following parameters were also assessed: Gleason score and stage of the main tumor, tumor volume, location of positive margin, GS at the positive margin, capsular incision with positive margin (CI) versus extraprostatic extension with positive margin (EPE-M). Results: After pathologic review, 127 patients were grouped as follows, 1. 26 with LL of3. During the 4.5 years of follow up 0, 9, 20 patients had BCR in each group respectively. Our data suggest that LL is associated with an increased risk of BCR (

Are certain high grade prostatic intraepithelial neoplasia subtypes associated with increased risk of prostatic adenocarcinoma?

Background: High grade prostatic intraepithelial neoplasia (PIN) is a presumed precursor lesion of prostatic adenocarcinoma (PCa). Studies have shown that extensive sampling of prostatic tissue and multifocal PIN are better predictors of cancer than unifocal PIN diagnosed on limited samples. However, currently there is no consensus on overall management and subsequent follow-up of PIN. Moreover, to the best of our knowledge, there are only a few studies on the morphologic patterns of PIN to stratify men with an increased risk of PCa. Thus, we aimed to study the correlation of the morphologic patterns of PIN with the subsequent progression to PCa. Design: We reviewed 323 patients who underwent transrectal needle biopsies and diagnosed with isolated PIN without current or prior diagnosis of carcinoma or atypical glands at our institution from 2009 to 2016. The following parameters were recorded: 1. Morphologic pattern of PIN which were divided into 4 categories with increasing complexity - flat, tufted, micropapillary and cribriform. When more than one pattern was present the more complex pattern was assigned. 2. Extent of PIN: Focal (1 core); multifocal (\u3e1 to 3 cores) and extensive (\u3e 3 cores). Results: Out of 323 patients, 7 patients were re-categorized as being negative for PIN and were excluded from final analysis. The distribution of the pattern and extent of PIN in the remaining 316 cases is provided in Table 1 & 2 respectively. No cancer was seen in cases with flat PIN, 10% of cases with tufted morphology progressed to PCa, 18% of cases with micropapillary morphology progressed to PCa and 25% of cases with cribriform morphology progressed to PCa. Out of 9 cases with micropapillary morphology, 4 cases were multifocal, 3 cases were extensive and 2 cases showed focal involvement. When only multifocal or extensive involvement was noted, 25% of the cases with micropapillary morphology progressed to PCa. Our data suggest that morphologic patterns of PIN are associated with progression to PCa (χ2 =17.850; df=3;
