Influencia de la actitud hacia la marca y su calidad percibida en la actitud hacia sus anuncios: ¿afectan la intención de compra?
Authors: Ugalde Cecilia
Published: May 2019

El presente estudio pretende explorar la influencia y relación que la actitud hacia una marca así como la calidad percibida de un producto o servicio tienen hacia sus anuncios publicitarios, y cómo cada uno de ellos influye, si lo hace, en la intención de compra de los consumidores. El estudio se centra en el área de servicios, partiendo de la recordación de un anuncio publicitario en el segmento restaurantes.Esta investigación explora entre otras una relación sobre la que no se encontraron estudios anteriores, la relación entre la calidad percibida de un producto o servicio y la actitud hacia sus anuncios publicitarios. Para esto se realizaron 250 encuestas al azar en la ciudad de Cuenca, para cuyo análisis se utilizó SPSS y EQS.Con base a este estudio se puede afirmar que la calidad percibida de una marca influye en la actitud hacia sus anuncios; mientras que la actitud hacia dicha marca no influye en la actitud hacia sus anuncios, pero sí lo hace en la intención de compra, lo que se presta para que a través de anuncios publicitarios se pueda mejorar la actitud hacia la marca si esta se ha visto dañada.El hecho de que la actitud que se tiene hacia un anuncio publicitario no desencadene en intención de compra, refuerza la necesidad de explorar factores que mejoren la efectividad de los anuncios publicitarios.

Development of a 3D Printed Neuroanatomy Teaching Model
Authors: El Bialy Safaa , Weng Robin , Jalali Alireza
Published: May 2019

Gross anatomy has been seen as one of the basic bodies of knowledge that must be mastered as part of medical training. Likewise, neuroanatomy has been seen as foundational to clinical neurosciences. However, Neuroanatomy is different from gross anatomy and this is due to the complexity of the central nervous system, moreover, some of its structures cannot be dissected or demonstrated in anatomy cadaveric lab. The use of anatomical models in medical curricula has been reported as an effective way in teaching and learning anatomy. They have been used to replace cadaveric material when the latter is difficult to acquire, or when the anatomical structures cannot be dissected like the brain ventricles for instance, moreover they have the privilege of visualizing the structures in a 3 dimensional modality. The goal of this study was to create a 3 D printed neuroanatomy model in order to complement the University of Ottawa anatomy models’ library, and help medical students visualize the pathway of different nervous tracts on a 3 D simulation model.To assist with this, 2D images of slices of the cerebrum, brainstem, cervical, thoracic, and lumbar spinal cord were downloaded online to be imported to Adobe Photoshop CC 2015. The images were manually converted to black and white, and separated into different layers to export each components separately into Tinker CAD (online software). The different components were then assembled on Tinker CAD to create 3D printer compatible files. The files were printed using white ABS on a Replicator 2X MakerBot printer at the library of University of Ottawa.
A Circumpolar Experience: How Social Determinants of Health, Climate Change, Grapes, and Medical Innovation are Related
Authors: Nayman Candace
Published: May 2019

This report shares my experience on an Arctic expedition with the Students on Ice Foundation. Social Determinants of Health (SDHs), including climate change, are considerably worse in Indigenous populations than the rest of Canada, and they carry profoundly negative implications for Indigenous healthcare. Climate change has a more significant effect at the poles than anywhere else globally, thus compounding the effects of SDHs and worsening Indigenous health. There are innovative ways in which SDHs and the effects of climate change can be mitigated and ways in which Indigenous healthcare can be improved, particularly with programs such as Students on Ice.
Coupling Culture and Medicine in Chile
Authors: Endres Kaitlin Marie Christine , Nicholls Mitchell Eric
Published: May 2019

This elective report provides an overview of a month-long Internal Medicine elective in Coronel, Chile completed by a first-year medical student from Ottawa and a second-year medical student from Western in July 2018. As a couple, we had the opportunity to apply to the International Federation of Medical Students Association (IFMSA) together in order to complete our international exchange in the same city. While in Chile, we had the opportunity to shadow many subspecialties, learn how one becomes a physician in South America, and gain exposure to Chilean culture and traditions from our host family. Our experience was unique in that it allowed us not only to learn about medicine and patient populations in Chile within our assigned hospital, but also from some of our family members who work as Chilean physicians we had the opportunity to visit.
Porcine Model of Donation after Cardiac Death (DCD) and Evaluation of Pulmonary Function Using Ex-vivo Lung Perfusion (EVLP)
Authors: Dhane Malek
Published: May 2019

Objective

The limiting factor when using lungs from donors after cardiac death (DCD) is the duration of warm ischemic time, which is linked to reperfusion edema. Within the context of lung shortages, and in order to avoid transplanting damaged lungs, ex-vivo lung perfusion (EVLP) has emerged as an innovative tool to preserve and recondition donor lungs. Using the EVLP technique in a porcine model, the purpose of this study is to determine the duration of warm ischemia that donor lungs can tolerate before they are viewed as non-viable for transplant.

Methods

This study is comprised of 5 groups (n=2-6/group).  Four groups endured different warm ischemic times, whilst the fifth group underwent cold ischemia. The lungs were subsequently perfused outside the body using the EVLP platform for four hours.

Results

120 minutes of warm ischemia is more damaging for lungs than 120 minutes of cold ischemia, even after being reconditioned on the EVLP platform (50,4 ± 8,9% vs. 3,3 ± 3,4% of weight gain). This would signify that two hours of warm ischemia is incompatible with transplantation. However, 90 minutes and 60 minutes of warm ischemia seems to have less of an effect on pulmonary functions. Indeed, the lungs of both these groups had less than 14% of weight gain and maintained oxygenating capacities (PaO2/FiO2 of 514 ± 12 and 586 ± 0 mmHg respectively.)

Conclusion

Lungs having been submitted to less than 90 minutes of warm ischemia and evaluated with EVLP may be suitable candidates for transplantation.
Efficacy and Toxicity of Treatments for Primary Central System Lymphoma: Review of the Recent Literature
Authors: Jay Mohammad , MacDonald David. A.
Published: May 2019

Primary Central Nervous system lymphoma (PCNSL) is an uncommon type of central nervous system lymphoma, most commonly presenting as hemiparesis and headache. Currently, there is a wide range of treatments for PCNSL, consisting of various permutations between chemotherapy, radiation and autologous stem cell transplant (ASCT). Although the backbone of PCNSL treatment consists of High-dose Methotrexate (HD-MTX), the role of combination versus single agent chemotherapy, combined modality (chemotherapy + radiation) versus chemotherapy or radiation alone, and the use of consolidative ASCT are contested. Surgery does not have a role in the treatment of PCNSL although stereotactic biopsies tend to help with symptomatic relief. Radiation monotherapy is generally reserved for patients with contraindications to chemotherapy or as a palliative measure. Combined chemotherapy and radiation treatment has been shown to have a great efficacy, although its increased neurotoxicity compared to chemotherapy alone is a major drawback. A growing body of research is focused on comparing the efficacy of various chemotherapeutic regimens. Currently, the MATRix regimen comprising of HD-MTX(3.5g/m2)-cytarabine/rituximab/thiotepa is widely used. The additional survival benefit of ASCT is contested although its role in the treatment of refractory or relapsed PCNSL is generally agreed upon. Finally, intrathecal HD-MTX has been shown to have added survival benefit when added to the standard therapies. Further retrospective and prospective studies are required to compare the efficacy and toxicity of various treatment options, with a focus on different chemotherapeutic agents and ASCT.

Authors: Varghese Jessy , Koothan Vijaya , Sujaritha V.
Published: May 2019

Background: Premenstrual syndrome is cyclical physical and behavioural symptoms that appear in days preceding menstruation and interfere with work or life style followed by a symptom free interval. The common affective and somatic symptoms seen are mood swings, irritability, anxiety, breast tenderness, weight gain and abdominal bloating. The present study was done to detect premenstrual syndrome and encourage students to seek treatment which would improve quality of life both socially and academically.Methods: A cross-sectional study was conducted over a period of three months from November 2018 to January 2019 among medical students in a tertiary care institute in Pondicherry. A detailed questionnaire regarding premenstrual symptoms and screening for depression was obtained from all study subjects. Diagnosis of premenstrual syndrome was done if there were at least one affective symptom like mood swings, insomnia, anxiety and one somatic symptom like abdominal bloating, breast complaints and weight gain.Results: Total of 207 students were screened out of whom 155 (74.87%) students were found to have premenstrual syndrome. 41 students did not have the same, 11 students were excluded as they were having endocrine disorders like polycystic ovarian syndrome and thyroid abnormalities. 60.6% had mild 38.4% moderate 4.5% had severe premenstrual syndrome. Commonest symptoms were mood swings 81.9% followed by anxiety 80% and fatigue 71.6% breast complaints and joint pains were seen in 71% equally so also abdominal bloating and weight gain which was seen in 67%. Depression was found in 52.9% of the students.Conclusions: Premenstrual syndrome is prevalent among medical students commonly and detecting it and encouraging students to seek treatment will help them perform better socially and academically.

Authors: Gandavaram Jyothi , Pamulapati Bindu Reddy
Published: May 2019

Background: Cervical malignancy is ranked second among the malignancies in females with breast carcinoma the first. Screening for cervical cancer by conventional cytology and supported by colposcopy and histopathology can easily identify the premalignant lesions and also other non-invasive inflammatory lesions of the cervix. Objective of this study was to find the correlation of Pap smear, colposcopic findings and colposcopic guide biopsy in evaluation of cervical lesions in women and to analyze the various risk factorsMethods: A prospective study for two years was conducted by department of obstetrics among women aged from 20-60 years. Socio demographic data, clinical history and examination were done and findings noted. Pap smear, colposcopy and colposcopic guided biopsy was done and findings were noted and analyzed foe sensitivity, specificity and compared with Pap smear.Results: In present study sensitivity of Pap smear for detecting lesions above LSIL was 28%, specificity 99.32%, PPV was 93.47%, negative predictive value 76.21% and accuracy of Pap smear was 78%. The sensitivity of colposcopy in detection of low grade lesions and above came out to be 80.2%, specificity 82.14%, positive predictive value 66.78%, negative predictive value 86.78% and accuracy of colposcopy was 84.65%.The incidence of preinvasive lesions (LSIL and HSIL) was 33.6% with LSIL (19.2%) and HSIL (14.4%) and of invasive lesions was 9.6%.Conclusions: This study suggests that accuracy of detection of cervical abnormalities is higher when cytology, colposcopic biopsy and colposcopy are used complimentarily in diagnosis of cervical lesions. Colposcopy eliminates the need for repeated follow up as in Pap smear which has low sensitivity.

Intestinal adhesions are bands of fibrous tissue created by the intimate contact of two injured surface tissues; these appear in 93% of the patient undergoing intra-abdominal or gastrointestinal surgery. The comorbidities associated with the formation of adhesions have an impact on quality care offered to patients, leading to an increase in healthcare. Goals of this study was to perform a review that includes different therapeutic alternatives in basic and clinical research to prevent the formation of postoperative abdominal peritoneal adhesions. A bibliographic search was conducted in different databases including Pub med, Medline, Cochrane, science direct, from the years 2000 to 2018 using the keywords: gastrointestinal adhesions, small bowel obstruction, prophylaxis, treatment. Only experimental and clinical articles were selected. The development of peritoneal adhesions in most of the experimental studies occurred with cecal abrasion, studying the effect of biodegradable materials, drugs and gels such as mXG Hydrogel. Nanofiber membranes, agents created with recombinant technology such as periostin antisense oligonucleotide and aerosol applications such as polysaccharide 4DryField PH, are positioned to replace in the future the actual limited mechanical barriers application commonly used in abdominal surgery such as seprafilm and interceed. There are several anti-adhesion agents in experimental phase with different mechanism of action that could be used in the short term to prevent the formation of post-surgical intestinal adhesions. The inclusion of gastrointestinal surgeons in basic research is increasing and necessary with multidisciplinary collaboration. It is expected in short term the study and development of a greater number of materials to minimize tissue trauma and decrease the formation of post-surgical adhesions.

Published: May 2019

Background: Thrombocyte is important and very essential component of blood and have significant role in maintenance of hemostasis. Thrombocyte count is an important investigation done in various acquired and congenital coagulable states which include conditions like pregnancy. Thrombocyte count is routinely done by automated hematology analyzer method. The automated hematology analyzer counters are not usually available at all centres especially in peripheral and rural side though thrombocytes can also be assessed from the peripheral blood smears, which can be easily and precisely done at any set up. Aim and objective of this study was to compare the thrombocyte estimation by peripheral blood smear method and automated hematology analyzer in pregnant women.Methods: Thrombocyte estimation was done from samples taken from 120 normal pregnant women between December 2018 to March 2019, where samples were Ethylene Diamine Tetra Acetic acid (EDTA) anticoagulated. Thrombocyte was counted manually using PBS (Leishman stain) and hematology analyzer (Sysmex XN1000 series). Thrombocyte counts were expressed in Mean and standard Deviation. Statistical analysis was done by student’s t test using MS excel and SPSS version 17.Results: Thrombocyte count by PBS have mean value of 2.04 lacs/mm3 with standard deviation of 0.56 lacs/mm3 and by automated method have mean value of 1.89 lacs/mm3 and standard deviation of 0.71 lacs/mm3 with p value 0.010. Thus, there was no statistically significant difference found between two methods.Conclusions: Estimation of thrombocyte count on the basis of manual thrombocyte count is a reliable technique and can be used to validate automated thrombocyte counts. It can also be used in under resourced laboratories, where there are no automated counters of good precision available. In fact, all the tests showing abnormal thrombocyte counts must be reported only after cross examining on PBS.

Authors: M. Mithun , . Dhandapani , . Venkatraman , J. Arun Daniel
Published: May 2019

Background: Atherosclerosis has been described as a lipid driven inflammatory disorder of the arterial wall. Smoking is one of the most common modifiable risk factors for atherosclerosis and is the major epidemiological factor in increasing morbidity and mortality of chronic heart diseases (CHD). The objectives of this study were based on to estimate the status of lipid profile in both smokers and non-smokers and compare with each other, to predict the 10 years risk of cardiovascular risk based on Framingham score in smokers and non-smokers.Methods: This retrospective, case-control study was conducted among 50 smokers (cases) and 50 normal individuals (controls) attending to the department of medicine during the period between December 2016 and May 2018. The socio-demographic data and clinical history was obtained using a semi-structured questionnaire and then patients were subjected to blood investigations including estimation of lipid profile by CHOD/PAP method.Results: The mean age of the study participants was 34.7±2.9 years. The duration of smoking among the smokers was 5.4±2.9 years on an average. There was a significant increase in serum cholesterol levels (245.6±39.8 versus 155.8±15.2 mg/dl), serum triglycerides (217.3±42.2mg/dl versus 127.4±10.6), LDL (171.1±35.2 versus 85.7±15.1 mg/dl) and VLDL (43.5±10.5 versus 15.3±5.5mg/dl) among the smokers versus non-smokers. There was a significant (p<0.001) decrease in HDL levels among the smokers (30.8±3.4 mg/dl) when compared with the non-smokers (44.8±5.3 mg/dl). There was a highly significant difference between Framingham risk scores of smokers and non-smokers.Conclusions: The study established that the lipid profile was deranged towards atherogenesis among the smokers when compared to the non-smokers which was reflected in the significant increase in risk as calculated by Framingham risk score.

Authors: Dhaulta Praveen , Panwar Vikas
Published: May 2019

Background: Acute kidney injury (AKI) is one of the most serious complications during the postoperative period of cardiac surgery. Multiple variables predict the ARF after cardiac surgery. Objective of this study was to evaluate the significance of pre and peri-operative variables which may help in predicting the chances of developing ARF after cardiac surgery.Methods: This study was an observational, prospective study conducted among patients who were scheduled to undergo open heart surgery under cardiopulmonary bypass.Results: In total, 50 patients who underwent open-heart surgery, ARF was seen in 5 patients, with the incidence rate of 10%. Acute renal failure was present in one patient with ejection fraction <35, 2 patients had ejection fraction between 35 to 50 and 2 patients with ejection fraction >50. It was seen in 4 patients with 1-2 hrs of cardiopulmonary bypass and in 1 patient with >2 hrs of cardiopulmonary bypass. ARF was also seen in 4 patients with hematocrit between 22-26% and in 1 patient with >26%.Conclusions: The study provided a clinical variable score that can predict ARF after open-heart surgery. The score enhances the accuracy of prediction by accounting for the effect of all major risk factors of ARF.

Authors: Relwani Prakash Ram , Redkar Neelam N. , Garg Deepanshu
Published: May 2019

Background: Dengue is a mosquito borne viral infection. It is the most common arboviral disease globally. In the year 2017, India had 1,53,635 cases of dengue with 226 deaths. Electrolyte disturbances reported in dengue infection are hyponatremia, hypokalaemia and hyperchloremia. Considering the serious nature of effects of dyselectrolytemias and high incidence of dengue in India, it is necessary to have a thorough understanding about electrolyte disturbances in Dengue, so as to predict, diagnose and treat them accordingly.Methods: This study was performed in a tertiary care centre in Mumbai, India. The study was a prospective observational cross-sectional study. 150 Patients diagnosed with Dengue were enrolled for the study. Patients’ demographic data, clinical history, examination findings and investigations including electrolyte values were recorded and analysed.Results: A higher incidence of dengue was seen in young age group among admitted patients (74%). Hyponatremia (45.33%) and Hypokalaemia (10.60%) were more commonly observed than hypernatremia (3.33%) and hyperkalaemia (3.33%). Hypochloraemia (6.66%) was seen slightly more than hyperchloraemia (6.00%). Fever was Present in 98.66%, retro orbital headache in 86.66%, vomiting in 56.00%, joint pain in 69.00%, lethargy in 70.66%, breathlessness in 36.00%, bleeding in 8.66%, abdominal pain /tenderness in 18.00%. 85.00% had low platelet count, 30.66% had low hemoglobin and 36.66% had leucopenia. Haematocrit was found to be less in 27.33% and high in 1.33%.Conclusions: From the above results we concluded that, there is a need to have a degree of suspicion about dyselectrolytemias while managing patients with Dengue. Also, patients need to be subjected to necessary lab investigations early during management so that if abnormalities are found, they can be promptly and appropriately managed as some of these abnormalities may lead to increased severity as well as mortality.

Authors: Ashrafganjoei Tahereh , Mirreza Soha , Eftekhariyazdi Mitra , Mortazavi Forough
Published: May 2019

Introduction: Acute fatty liver of pregnancy (AFLP) is a rare but lethal disease with liver involvement that appears in the third trimester of pregnancy. There is no specific treatment for AFLP. Because liver dysfunction is the most pathogenesis in AFLP the following hypothesis will be raised that plasma exchange can be useful.
Case Report: A 26-year-old mother was referred to our emergency ward with AFLP. The ultrasonography reported a single alive anhydramnios fetus at 34 weeks and fatty liver G1-2. Emergent cesarean was performed and the patient was then admitted to the intensive care unit. The day after surgery, our patient developed periumbilical tenderness and displayed abnormal coagulative factors. Ultrasonography reported 500cc liquid in the abdominal space. Relaparotomy was performed and during the next several days, her general condition worsened and supportive treatment was not effective and the patient experienced a seizure. We started plasmapheresis and after 10 days platelet levels started to rise, lactate dehydrogenase began to reduce, the edema reduced significantly, and her orientation became better. We continued plasmapheresis for about 20 sessions. After one month, the patient was discharged from the hospital in good general condition.
Conclusion: Plasmapheresis may be effective in the treatment of fatty liver of pregnancy.

The Hexose efflux from the peeled grape berry
Authors: Božović Predrag Nenad , Rogiers Suzy , Deloire Alain
Published: May 2019

Aim: The transport of sugars into grape berry mesocarp cells across the plasma and vacuolar membranes after onset of ripening is a complex process. Elements of the sugar transport mechanism may be assessed by exposing the mesocarp cells and investigating sugar movement across the membranes. The purpose of this study was to gain insights into the nature of the transport mechanism by creating conditions conducive to hexose efflux from the peeled berry.Methods and results: The experimental technique employed was a derivate of the ‘berry-cup’ technique. The skin of ripening cv. Shiraz berries was peeled in situ and, after an initial wash, hexose efflux into a collection medium (MES buffer) was monitored. Additionally, during the period of intensive sugar accumulation (one week after veraison) and two weeks later, hexose efflux was assessed following three modifications: (i) using berries excised from the vine, (ii) using MES buffer (2-(N-morpholino)ethanesulfonic acid, pH 5.5) containing PCMBS (p-chloromercuribenzenesulfonic acid, 1mM), and (iii) using cold (10°C) or warm (40°C) MES buffer. Hexose quantities collected into the buffer were dependent on ripening stage and buffer temperature, but they were not dependent on an intact berry-to-cluster connection. The inhibitory effect of PCMBS was observed early in ripening, but not two weeks later.Conclusions: These results lead us to the conclusion that the origin of the collected hexoses was vacuolar as opposed to vascular, and that the hexose efflux mechanism is differently sensitive to PCMBS at the two stages of ripening.Significance and impact of the study: This simple technique was effective at providing insights into hexose transport within the grape berry at the cellular level.

The Impact of Hard Coral Bleaching in Coral and Macrozoobenthos Fish Communities in Tejakula, Buleleng, Bali Water Areas

ABSTRACT
Coral bleaching is one of the consequences of global climate change, as the rise of temperature negatively impacts the ecological balance of reef ecosystems. Bleached coral reefs lose their zooxanthellae, increasing vulnerability to infection and disease and consequently, causing population decline of macrozoobenthos and reef fish communities which prey on coral-consuming organisms. This research aims to determine the degree of coral reef damage and its impact on fish and macrozoobenthos population. The survey was conducted on 3 stations in Tejakula waters with the reef check method. Results show that coral reef death reaches 5-7.5%, with algal coverage of 3.125%. Kepe-kepe fish which prey on coral-consuming animals were also found in relatively high abundance. The presence of herbivore fish and macrozoobenthos help reduce algal cover. Meanwhile, the presence of coral-consuming and predator fish indicate that the coral reef ecological system has mostly returned to normal.

Terdapat lima kecacatan dalam pembuatan baling-baling blower U-8 yaitu cacat berlubang, permukaan kasar, retak, kekasaran meluas dan deformasi. Kecacatan yang dialami sebesar 1204 produk atau 20,27% dari jumlah produksi. Permukaan kasar merupakan jenis cacat yang mempunya tingkat kecacatan terbesar yaitu 53,08% dari total kecacatan atau sebanya 627 produk. Untuk mengurangi cacat produk baling-baling blower U-8 harus difokuskan pada jenis kecacatan permukaan kasar. Untuk mengurangi jenis kecacatan tersebut operator harus lebih teliti dalam melakukan pemeriksan cetakan pasir, bahan baku aluminium juga harus bersih dan sebagian dari bahan ingot (batangan), campuran pasir cetak harus diperhatikan, kondisi lingkungan harus menerapkan 5P dan menambah fasilitas kerja( lampu penerangan), pergantian alat seperti mold dan penambahan pengkur suhu pada tungku peleburan.

Using Seven Tools Method in CV. Anugerah Abadi
ABSTRACT
There are five defects in the manufacture of U-8 blower blades which are hollow defects, rough surfaces, cracks, widespread roughness, and deformation. Defects experienced by 1204 products or 20.27% of total production. The rough surface is a type of defect that has the biggest disability rate of 53.08% of the total disability or Seba 627 products. To reduce the defects of the U-8 blower products should be focused on the types of rough surface defects. In order to reduce the type of disability the operator must be more careful in examining the sand mold, the aluminum raw material must also be clean and part of the ingot material (bar), the mixture of printed and must be considered, the environmental conditions must apply 5P and add work facilities (lighting) replacement tools such as mold and the addition of temperature drier to the melting furnace.

Background: Heterosis breeding is the most useful method for yield increment around the globe. Heterosis is an intriguing process to develop superior offspring to either parent in the desired character. The biomass vigor produced during seedling emergence stage has a direct influence on yield heterosis in plants. Unfortunately, the genetic basis of early biomass vigor in hybrid cotton is poorly understood.
Results: Three stable performing F1 hybrids varying in yield heterosis named as high, medium and low hybrids with their inbred parents were used in this study. Phenotypically, these hybrids established noticeable biomass heterosis during the early stage of seedling growth in the field. Transcriptome analysis of root and leaf revealed that hybrids showed many differentially expressed genes (DEGs) relative to their parents, while the comparison of inbred parents showed limited number of DEGs indicating similarity in their genetic constitution. Further analysis indicated that expression patterns of most DEGs were overdominant in both tissues of hybrids. According to GO results, functions of overdominance genes in leaf were enriched for chloroplast, membrane, and protein binding, whereas functions of overdominance genes in root were enriched for plasma membrane, extracellular region, and responses to stress. We found that several genes of circadian rhythm pathway related to LATE ELONGATED HYPOCOTYL (LHY) showed downregulated overdominant expressions in both tissues of hybrids. In addition to circadian rhythm, several leaf genes related to Aux/IAA regulation and many root genes involved in peroxidase activity also showed overdominant expressions in hybrids. Twelve genes involved in circadian rhythm plant were selected to perform qRT-PCR analysis to confirm the accuracy of RNA-seq results.
Conclusions: Through genome-wide comparative transcriptome analysis, we strongly predict that overdominance at gene expression level plays a pivotal role in early biomass vigor of hybrids. The combinational contribution of circadian rhythm and other metabolic processes may be controlled vigorous growth in hybrids. Our result provides an important foundation for dissecting molecular mechanisms of biomass vigor in hybrid cotton.

Background

The ability to accurately and comprehensively identify genomic variations is critical for plant studies utilizing high-throughput sequencing. Most bioinformatics tools for processing next-generation sequencing data were originally developed and tested in human studies, raising questions as to their efficacy for plant research. A detailed evaluation of the entire variant calling pipeline, including alignment, variant calling, variant filtering, and imputation was performed on different programs using both simulated and real plant genomic datasets.

Results

A comparison of SOAP2, Bowtie2, and BWA-MEM found that BWA-MEM was consistently able to align the most reads with high accuracy, whereas Bowtie2 had the highest overall accuracy. Comparative results of GATK HaplotypCaller versus SAMtools mpileup indicated that the choice of variant caller affected precision and recall differentially depending on the levels of diversity, sequence coverage and genome complexity. A cross-reference experiment of S. lycopersicum and S. pennellii reference genomes revealed the inadequacy of single reference genome for variant discovery that includes distantly-related plant individuals. Machine-learning-based variant filtering strategy outperformed the traditional hard-cutoff strategy resulting in higher number of true positive variants and fewer false positive variants. The 2-step imputation which utilized a set of high-confidence SNPs as the reference panel showed up to 60% higher accuracy than direct LD-based imputation method.

Conclusions

Programs in the variant discovery pipeline have different performance on plant genomic dataset. Choice of the programs is subjected to the goal of the study and available resources. This study serves as an important guiding information for plant biologists utilizing next-generation sequencing data for diversity characterization and crop improvement.
