Sterols of the heterotrophic dinoflagellate, pfiesteria piscicida (dinophyceae): is there a lipid biomarker? 1

Within U.S. waters, blooms of the dinoflagellate, Pfiesteria piscicida, have been recorded on an almost regular basis in the Chesapeake Bay and surrounding mid‐Atlantic regions for the last two decades. Despite the apparent significance of such blooms to the environment and human health and the attendant economic consequences, little work has addressed the physiology and biochemistry, particularly that of sterol composition, of P. piscicida. GC‐MS characterization of trimethylsilyl ether derivatives of sterols from free sterol and sterol ester fractions was performed in an effort to determine whether P. piscicida produces unique sterols that may serve as potential biomarkers. This characterization revealed that like most dinoflagellates, the majority of sterols was present as free sterols. Furthermore, the profile of free sterols was found to resemble those of photosynthetic dinoflagellates, with the dominant compound being the previously reported dinoflagellate sterol, dinosterol. A number of other 4α‐methyl‐substituted sterols and steroidal ketones common to other dinoflagellates were also identified. No strong candidate(s) for a unique sterol biomarker was present.
Role of Food Porn: Luxury Food Desire among Adolescents

Luxury consumption is excessively done by individuals to show off their wealth and success. Thus, social media platforms are enhancing their luxury consumption desire and showing off to others. The need for status, need for uniqueness, and attitude influences in a positive way towards food porn. The purpose of this study was to understand the new concept of food porn how it affects and mediates between the different relationships of an individual's personality traits and luxury food desire. The results have shown that the new construct food porn is mediating well between the NFS and LFD, NFU and LFD, and ATT and LFD. In the future, more work can be done to develop food porn theory and further see food porn in different roles.
Measuring Free-Living Physical Activity With Three Commercially Available Activity Monitors for Telemonitoring Purposes: Validation Study

Background Remote monitoring of physical activity in patients with chronic conditions could be useful to offer care professionals real-time assessment of their patient’s daily activity pattern to adjust appropriate treatment. However, the validity of commercially available activity trackers that can be used for telemonitoring purposes is limited. Objective The purpose of this study was to test usability and determine the validity of 3 consumer-level activity trackers as a measure of free-living activity. Methods A usability evaluation (study 1) and validation study (study 2) were conducted. In study 1, 10 individuals wore one activity tracker for a period of 30 days and filled in a questionnaire on ease of use and wearability. In study 2, we validated three selected activity trackers (Apple Watch, Misfit Shine, and iHealth Edge) and a fourth pedometer (Yamax Digiwalker) against the reference standard (Actigraph GT3X) in 30 healthy participants for 72 hours. Outcome measures were 95% limits of agreement (LoA) and bias (Bland-Altman analysis). Furthermore, median absolute differences (MAD) were calculated. Correction for bias was estimated and validated using leave-one-out cross validation. Results Usability evaluation of study 1 showed that iHealth Edge and Apple Watch were more comfortable to wear as compared with the Misfit Flash. Therefore, the Misfit Flash was replaced by Misfit Shine in study 2. During study 2, the total number of steps of the reference standard was 21,527 (interquartile range, IQR 17,475-24,809). Bias and LoA for number of steps from the Apple Watch and iHealth Edge were 968 (IQR −5478 to 7414) and 2021 (IQR −4994 to 9036) steps. For Misfit Shine and Yamax Digiwalker, bias was −1874 and 2004, both with wide LoA of (13,869 to 10,121) and (−10,932 to 14,940) steps, respectively. The Apple Watch noted the smallest MAD of 7.7% with the Actigraph, whereas the Yamax Digiwalker noted the highest MAD (20.3%). After leave-one-out cross validation, accuracy estimates of MAD of the iHealth Edge and Misfit Shine were within acceptable limits with 10.7% and 11.3%, respectively. Conclusions Overall, the Apple Watch and iHealth Edge were positively evaluated after wearing. Validity varied widely between devices, with the Apple Watch being the most accurate and Yamax Digiwalker the least accurate for step count in free-living conditions. The iHealth Edge underestimates number of steps but can be considered reliable for activity monitoring after correction for bias. Misfit Shine overestimated number of steps and cannot be considered suitable for step count because of the low agreement. Future studies should focus on the added value of remotely monitoring activity patterns over time in chronic patients.
GENETIC STUDY OF DAIRY CATTLE AND BUFFALO BULLS BASED ON GROWTH, MILK PRODUCTION AND REPRODUCTIVE TRAITS

The present investigation aimed to conduct a genetic study of dairy cattle and buffalo bulls based on economic traits and their phenotypic correlation. The means of various economic traits in both the species are presented. Cattle bulls reported a better libido score, Flehmen response, requirement of mounting stimulus and semen volume, conception rate and expected predicted difference for milk production. Significant differences were observed between cattle and buffalo in growth traits (birth weight, 3 months body weight, 6 months body weight), reproduction traits (individual semen motility, post thaw semen motility and requirement of mounting stimulus). Association studies conducted among various growth, reproduction and production traits revealed that, a positively high and significant association existed among growth traits and individual motility with the number of semen doses per collection in crossbred bulls. Three month body weight was associated significantly with expected predicted difference (P<0.05) in crossbred bulls. However in the case of Murrah bulls, a significantly high correlation was observed among body weights at birth and at three months of age.
Immigration and Entrepreneurship in the United States

Immigrants can expand labor supply and compete for jobs with native-born workers. But immigrants may also start new firms, expanding labor demand. This paper uses US administrative data and other data sources to study the role of immigrants in entrepreneurship. We ask how often immigrants start companies, how many jobs these firms create, and how firms founded by native-born individuals compare. A simple model provides a measurement framework for addressing the dual roles of immigrants as founders and workers. The findings suggest that immigrants act more as “job creators” than “job takers” and play outsized roles in US high-growth entrepreneurship. (JEL J15, J22, J23, J61, L26, M13)
Water stress induced changes in concentrations of proline and total soluble sugars in nodulated alfalfa (Medicago sativd) plants

Susceptibility of alfalfa (Medicago saliva L. cv. Aragon) nodules and leaves to water stress has been investigated. Nodule acetylene reduction activity (ARA), leaf CO2 exchange rate (CER) as well as soluble protein, proline and total soluble sugar (TSS) contents were determined during drought. Water status was estimated as water potential (Ψw) and Relative water content (RWC) of the respective tissues. Maximum rates of ARA required higher Ψw than CER. Nodules had lower RWC for a given Ψw than leaves. Water stress reduced soluble protein content in both tissues; however, the decline in soluble protein content was detected at greater Ψw in nodules than in leaves. Proline and TSS increased in leaves and nodules, and again the threshold Ψw triggering such accumulation was higher in nodule tissues. Oior results suggest that alfalfa nodules are more susceptible to water shortage than leaves. Effects of accumulated TSS and proline upon leaf and nodule physiology are discussed in relation to protein stability (proline), pH control (proline) and osmotic adjustment (proiine and TSS). The TSS accumulation induced by water stress suggests that substrate shortage would not be the primary effect of drought on nodule activity.
Influenced of zinc application on macro and micro nutrients content at different growth stages of wheat (Triticum aestivum L.)

Zinc deficiency is major problem in cereal crops. Therefore, zinc agronomic fortification of wheat and other cereal crops is being urgently addressed and highly prioritized as a research topic. Increasing the zinc content of food crop resulting in better crop production is an important global challenge. An investigation was carried out to find out the influenced of zinc application on content of macro and micro nutrients in wheat (Triticum aestivum L.). There were seven treatments of different levels of zinc was applied in this experiment generated using completely randomized design. The significantly highest macro and micro nutrients content were observed in the treatment of soil application of RDF + ZnSO4 @ 30 kg ha at the time of sowing. It is concluded that the soil application of ZnSO4 @ 30 Kg ha + RDF (80:40:40 kg ha N, P2O5, K2O) at the time of sowing recorded highest wheat macro and micro nutrients content.
Automated Tool for Resume Classification Using Sementic Analysis

Recruitment in the IT sector has been on the rise in recent times. Software companies are on the hunt to recruit raw talent right from the colleges through job fairs. The process of allotment of projects to the new recruits is a manual affair, usually carried out by the Human Resources department of the organization. This process of project allotment to the new recruits is a costly affair for the organization as it relies mostly on human effort. In the recent times, software companies round the world are leveraging the advances in machine learning and Artificial intelligence in general to automate routine tasks in the enterprise to increase the productivity. In the paper, we discuss the design and implementation of a resume classifier application which employs an ensemble learning based voting classifier to classify a profile of a candidate into a suitable domain based on his interest, work-experience and expertise mentioned by the candidate in the profile. The model employs topic modelling techniques to introduce a new domain to the list of domains upon failing to achieve the threshold value of confidence for the classification of the candidate profile. The Stack-Overflow REST APIs are called for the profiles which fail on the confidence threshold test set in the application. The topics returned by the APIs are subjected to topic modelling to obtain a new domain, on which the voting classifier is retrained after a fixed interval to improve the accuracy of the model.Overall, emphasis is laid out on building a dynamic machine learning automation tool which is not solely dependent on the training data in allotment of projects to the new recruits. We extended our previous work withnew learning model that has the ability to classify the resumes with better accuracy and support more new domains
Field Assessment of Influence of Organic Fertilizers on Microbial Profile and Sustainable Maize Production in a Flood Plain in Nigeria

The stabilization and utilization of organic fertilizers in flood plain for sustainable agriculture in the tropics was studied in field experiment conducted at Etinan wetland soil (EW) of Akwa Ibom State, Nigeria in the tropics during two cropping seasons (C. S.) to study the effects of two composted and stabilized organic fertilizers (poultry droppings, PD and cow dung, CD) on the microbial density and structure, soil properties, growth and yield of corn (Zea mays) according to standard procedures. The two treatments plus control, (the unfertilized plots) were arranged in a randomized block design with two replications giving three main plots; poultry manured plots (PM), cow manured plots (CM) and the control plots, C, which were sectioned into nine subplots on which was a total of 81 mounds on the study site. Results showed that PD and CD (450 gm2=4500 kgha-1) incorporated into the EW produced higher mean microbial density (Total heterotrophic bacterial counts, THBC=log 7.636 and 8.64, total actinomycetes counts, TAC=log 6.57& 6.62, diazotrophic bacterial counts, DBC=log 5.35 & 5.50 and total fungal counts, TFC=log 5.38 & 5.45 cfug-1) in both fertilized plots during the 1st & 2nd C. S respectively than in the control with 6.62 & 7.49, 5.59 & 5.52, 5.44 & 5.54, 4.5 & 5.49 cfug-1 of THBC, TAC, DBC and TFC respectively. It was also shown that PD and CD application into EW produced higher physicochemical properties, nutrient salts, compared to the C. Growth/yield of the test crop, Zea mays were increased in the PM followed by CM compared to C in the EW during both C. S. Using the mean difference of two years, plants of PM had highest grain yield (4.16±0.16t t/acre) compared to (2.84±0.31t/acre) and (0.09±0.23t/acre) of CM and C respectively. The effects of one time application of the organic fertilizers (without reapplication on the 2nd C. S) indicated higher crop harvest index, H. I. (0.63 and 0.64) of treatment plots compared to 0.19 and 0.20 of the C. Therefore, utilization of PM to soils is recommended for sustainable crop production especially maize in the flood plain and in the tropics as a whole. It is also recommended that the CD could serve as a suitable substitute in the absence of PD. Wetland soils in the tropics should be converted from the hitherto wasteland to useful and sustainable arable lands with the utilization of stabilized and composted organic fertilizers.
Relative Importance of Reproductive Biology and Establishment Ecology for Persistence of a Rare Shrub in a Fragmented Landscape

Abstract: Verticordia fimbrilepis (Turcz) ssp. fimbrilepis (Myrtaceae) is an endangered shrub that occurs in a number of populations varying in size and landscape context. We compared the importance of factors associated with its reproductive biology with that of factors influencing the regeneration niche in survival of small, isolated populations in contrasting habitat fragments. Small populations on road verges had equal or greater diversity of insect visitors to flowers, rates of pollination, and seed production compared with larger populations in conservation reserves. V. fimbrilepis seeds remained dormant in the soil for at least 30 months, and germination was stimulated by smoke. Plants were killed by fire, but mass recruitment from soil‐stored seed reserves occurred in the first and second winters following fire. Our studies showed some seedling recruitment between fires, but this was strongly related to the availability of competition‐free establishment sites. Whether this is enough to replace older plants as they die and thereby sustain stable populations is unknown and probably varies with the landscape. Environmental variation between fire episodes influenced population size. Drought increased mortality, but wetter years encouraged interfire recruitment. Most populations are declining and cannot recover without the occurrence of fire. In a fragmented agricultural landscape, fire suppression is the primary management practice. This may adversely affect rare species such as V. fimbrilepis and others with similar life histories that rely on a particular fire regime to persist. Population persistence is more likely to be related to stochastic environmental events than to factors associated with reproductive biology.
Bacteria and Antibiotic Susceptibility Patterns of Cerebrospinal Fluid Isolated in Children with Bacterial Meningitis at Sanglah Hospital, Bali from 2016 to 2018

Periodic review from laboratory about the pathogens causing the bacterial meningitis and its antimicrobial sensitivity test result is important to determine the most common etiology of meningitis, since they can be varied according to time, geography, and patient’s age. This study is a retrospective descriptive study. Affordable population in this study was children with positive cerebrospinal fluid culture results who were treated in Pediatric ward at Sanglah hospital, Denpasar from January 1st, 2016 until December 31st, 2018. The study used secondary data from the microbiology register in Clinical Microbiology Laboratory and medical record of Sanglah Hospital. This study employed total sampling method to collect samples. There were 52 samples that obtained in this study. Most of them were gram negative bacteria (53.8%). The most common gram negative bacteria found were Pseudomonas sp, with Pseudomonas stutzeri. The most common gram positive bacteria found were Staphylococcus sp, with Staphylococcus hemolitikus. Vancomycin, Linezolid and Tigecyclin have high sensitivity against gram positive bacteria. Carbapenem, aminoglycoside and fourth generation of cephalosporine still had high sensitivity against gram negative bacteria. About 26.9% of bacterias were multidrug resistant organisms (MDRO) and most of them (78.6%) were gram positive. Ceftriaxone as our empirical therapy has low sensitivity (30%) to gram positive bacteria and moderate sensitivity to gram negative bacteria (53.57%). Resistance to cephalosporin might be quite high in this particular clinical setting due to high number of MDRO. It should be taken into account before giving treatment for bacterial meningitis.
Pathogenic Variability in Australian Isolates of Phytophthora cinnamomi

Forty-two isolates of Phytophthora cinnamomi were obtained from native vegetation and horticultural crops within Australia. They represented a broad spectrum of geographical and host origins, both mating types, and all identified Australian isozyme genotypes. All isolates were tested for their pathogenicity to a single clone of Eucalyptus marginata by inoculation of soil in which plants were growing. Differences in pathogenicity were expressed as extent of root damage, reduction of plant growth, period to first visible disease symptoms and time to plant death. Significant variation between isolates was detected. Pathogenicity was unrelated to mating type and isozyme properties. A subset of these 42 isolates encompassing a range of virulence gave generally consistent rankings for pathogenicity variates when re-inoculated twice into plants derived from the original clone. This suggests that pathogenicity is a relatively stable characteristic. Detection of differences in susceptibility to P. cinnamomi between three selected E. marginata. clones was influenced by the pathogenicity of isolates. Only the more pathogenic isolates were useful in this regard. Seedling stems of five eucalypt species were inoculated with virulent and less virulent isolates of P. cinnamomi. This method detected variation in both pathogenicity in the fungus and susceptibility in the host species. Variation in pathogenicity within Australian populations of P. cinnamomi should be taken into account by the choice of isolates of proven virulence when selecting for resistance in trees and other woody hosts.
Biodiversity of the Pelagic Ocean

Abstract: This paper reviews knowledge of biodiversity in open ocean pelagic communities and discusses the possible causal factors for the patterns. The oceanic pelagic ecosystem is by far the largest on Earth and, although locally its assemblages may be as rich as many terrestrial ecosystems, its global diversity (at both a species and an ecosystem level) is low. There are latitudinal trends in pelagic species diversity similar to those in many terrestrial taxa. High species richness in the oceans, however, tends to be associated with regions of low productivity that lack strong seasonality in the production cycle. The richest zones occur at the boundaries between different types of oceanic water where different faunas are mixed together, but the geographical locations of these boundaries are unstable and shift seasonally by hundreds of kilometers. If high diversity is emphasized in the development of protocols for conservation, then not only will the oceans receive low priority in conservation and resource management, but the regions most important in terms of process will also be overlooked. The scales of oceanic systems are so large that the methodologies developed for terrestrial conservation and resource management are inapplicable. Biodiversity may be regarded as the principal criterion for developing management strategies, yet the links (if any) between the ecological processes in the ocean that play such an important role in global homeostasis remain poorly characterized. The basis for a predictive understanding of the interaction between diversity and ecological process can be greatly enhanced relatively inexpensively by systematically collating existing data and working up extant collections of material
A 2-year Review of Wound Outcome Following Primary Skin Closure After Laparotomy for Typhoid Ileal Perforation in Bida, Nigeria

Introduction: Laparotomy wound for typhoid ileal perforation is a dirty wound and is usually associated with wound complications and prolonged hospital stay. Delayed primary wound closure which for long has been the most common practice after laparotomy for typhoid peritonitis is now considered to be of little significance in preventing surgical site infection (SSI). We aimed to document the incidence, severity and management of wound complications when primary closure of abdominal wounds was performed following laparotomy for typhoid ileal perforation. Patients and Methods: This was a retrospective study of all patients who had primary abdominal wound closure following laparotomy for typhoid ileal perforation in Federal Medical Centre, Bida from January 2017 to December 2018. Results: There were 71 patients with the age ranges from 2 to 41 years and their median age was 15 years who had laparotomy for typhoid ileal perforation during the study period. All 71 patients had primary closure of their abdominal wounds, however two of them died within 72 hours of operation and were excluded from the study. There were males 38 (55.1%) and females 31 (44.9%) with a male to female ratio of 1.2:1. There was primary wound healing in 23 (33.3%) patients while 44 (63.8%) of them developed incisional surgical site infections (SSI) and 2 (2.9%) developed organ space SSI. Of the 44 patients that had incisional SSI, 33 (75.0%) were superficial and 11 (25.0%) were deep. Other complications noted from the study were faecal fistulae 3 (4.3%) and incisional hernia (4.3%). Conclusion: Though a high incidence of wound morbidity is not unexpected in situation of primary closure of laparotomy wound for bacteria peritonitis, an aggressive wound management may help to reduce the incidence and severity of wound complications in such situations.
A splice variant of PGRP‐LC required for expression of antimicrobial peptides in Anopheles gambiae

Abstract Members of the peptidoglycan recognition protein (PGRP) family play essential roles in different manifestations of immune responses in insects. PGRP‐LC, one of seven members of this family in the malaria vector Anopheles gambiae produced several spliced variants. Here we show that PGRP‐LC, and not other members of the PGRP family nor the six members of the Gram‐negative binding protein families, is required for the expression of antimicrobial peptide genes (such as CEC1 and GAM1) under the control of the Imd‐Rel2 pathway in an A. gambiae cell line, 4a3A. PGRP‐LC produces many splice variants that can be classified into three sub‐groups (LC1, LC2 and LC3), based on the carboxyl terminal sequences. RNA interference against one LC1 sub‐group resulted in dramatic reduction of CEC1 and GAM1. Over‐expression of LC1a and to a lesser extent LC3a (a member of the LC1 and LC3 sub‐group, respectively) in the 4a3A cell line enhances the expression of CEC1 and GAM1. These results demonstrate that the LC1‐subgroup splice variants are essential for the expression of CEC1 and GAM1 in A. gambiae cell line.
