A field experiment was conducted during Kharif season at Crop Research Farm of Tirhut College of Agriculture, Dholi in 2017 to observe the effect of different levels of potassium on yield and economics of Kharif maize. The experiment was laid out in Randomized block design with four replications and nine treatments at a different level of potassium (0, 30, 60, 90, 120 and 150 kg ha-1) in which three treatments T7, T8 and T9 were along with 5 tons of FYM. There were no marked effect of different treatments on the number of cob plant-1, length of cob, the girth of cob and test weight. However, the number of grains cob-1 was found significantly higher in treatment T9 (T4 + 5 t FYM ha-1). Grain yield, stover yield and stone yield were significantly influenced by different treatments. The maximum grain yield (63.19 q ha-1), stover yield (101.61 q ha-1) and stone yield (14.61 q ha-1) were recorded under treatment T9 (T4 + 5 t FYM ha-1). Economics of different treatments indicated that by higher grain yield, treatment T9 (T4 + 5 t FYM ha-1) exhibited maximum gross returns, net returns and B:C ratio of Rs 90,046 ha-1, Rs 47,987 ha-1 and 1.14, respectively.

Published: March 2020

Aims: This study was undertaken to investigate the antifungal activities of Securidaca longepedunculata and Acacia gourmaensis bark hydro-ethanolic extract against Fusarium solani, Fusarium moniliforme and Curvularia lunata and to evaluate the percentages of germination and infection of infected rice seeds.
Methods: Different extract concentrations ranging from 0.25, 0.5 and 1% were tested during 15 days using poisoned food technique method for in vitro antifungal activity against above three fungal strains. The same concentrations of extract were used to evaluate in vivo antifungal activity on rice seeds infected by these three fungal strains.
Results: The extract of Securidaca longepedunculata had antifungal effect on Fusarium solani and Fusarium moniliforme and completely inhibited its mycelial growth at all tested concentrations (0.25, 0.5 and 1%). Curvularia lunata mycelial growth was inhibited of 84.7% by 1% Securidaca longepedunculata extract after five days of culture. However, mycelial growth of F. solani, F. moniliforme and C. lunata were increased with increasing concentration of Acacia gourmaensis extract. It has been observed that when Securidaca longepedunculata hydro-ethanolic extract concentration increased up to 1%, seeds germination percentage decreased for all infection. In contrast, the opposite was observed for Acacia gourmaensis extract. Likewise, seeds infection decreased with the highest concentration (1%) of Securidaca longepedunculata for all infection, whereas the opposite was observed with Acacia gourmaensis extract.
Conclusion: This study showed that S. longepedunculata hydro-ethanolic extract has more antifungal activity against seed-borne fungi (F. solani, F. moniliforme and C. lunata) than A. gourmaensis in vitro and in vivo. Results show that Securidaca longepedunculata hydro-ethanolic bark extract can be used as a potential antifungal agent in the management of some rice fungal diseases. Acacia gourmaensis extract, at low concentration, could be used in rice seed treatment to increase seed germination.

Expression of 1L-myo-Inositol -1-Phosphate Synthase (EC 5.5.1.4) is Deregulated in the Cerebellum of Curly Tail Mutant Mice
Authors: Alebous Hana Dawood , Steele Erika M. , Johnson Margaret Dean 
Published: March 2020

Previous research, defining spatial control of inositol phosphate biosynthesis in the developing brain of CBA (normal) and CT [curly tail (ct-CT) and straight tail (st-CT)] mutant mice implicated a role for 1l-myo-inositol 1-phosphate synthase (MIP) in normal functioning of the central nervous system. Biochemical research indicated that MIP enzymatic activity, conversion of glucose 6-phosphate into inositol phosphate, is highest in the cerebellum of ct-CT and lowest in st-CT, when compared to that of CBA mice.
Here, we utilized microscopic and biochemical investigations to analyze and extend previous findings of MIP expression in the cerebellum. Results of this research indicated that MIP expression correlates, well, with its enzymatic activity in the cerebellum of CBA and CT mutant mice. Statistical analyses of fluorescent micrographs detected a significant difference in fluorescence intensity between MIP from ct-CT, st-CT, and CBA mice.
These data support vital links between inositol phosphate biosynthesis, MIP expression, and normal functioning of the cerebellum. Moreover, published data, identifying significant behavioral differences in the CT mutant, as well as data linking motor and non-motor cerebellar functions to abnormal levels of inositol, support the conclusion that aspects of normal cerebellar functions require temporal and spatial control of inositol phosphate biosynthesis, MIP expression.

Published: March 2020

Aim: To describe a rare case of pelvic desmoid tumour simulating as a huge uterine leiomyoma causing a diagnostic dilemma in a premenopausal woman.
Case Presentation: This was a 44-year-old, para 2 (2 alive) who was referred to our gynaecology clinic from a secondary health facility on account of slowly increasing abdominal swelling of 2 years duration. There was no nausea, vomiting or diarrhoea. There was associated mild to moderate dull lower abdominal pain that did not radiate to any other part of the body. There was no change in her monthly menstrual flow. Physical examination revealed a pelvic mass about 32 weeks pregnancy size and firm. Computed Topography scan showed a huge pedunculated sub-serous uterine fibroid. A huge mass adherent to the anterior surface of the body of the uterus was completely surgically excised at exploratory laparotomy. Histology of the excised tumour revealed a definitive histological diagnosis of pelvic desmoid tumour. The patient was clinically stable and discharged home 10 days post operation and was followed-up on out-patient gynaecology clinic basis.
Discussion: Pelvic desmoid is a rare mesenchymal tumour caused by abnormal proliferation of fibroblasts. It is three times more common in women and occurs mostly between 25 and 35 years of age which correspond to the same age peak incidence for uterine fibroids. The tumour can easily be misdiagnosed as uterine leiomyoma and imaging cannot reliably distinguish the two conditions.
Conclusion: Pelvic desmoid tumour should be considered as a differential diagnosis in premenopausal women who present with abdominal swelling. Relevant clinical history, Radiological imaging and Histopathological assessment are essential in making prompt accurate diagnosis.

ObjectiveThe assessment of racial differences in pain and function outcome following knee arthroplasty (KA) has received little attention despite very substantial literature exploring a variety of other prognostic factors. The present study was undertaken to determine whether race was associated with KA outcome after accounting for potential confounding factors.MethodsWe conducted a secondary analysis of a randomized clinical trial of 384 participants with moderate‐to‐high pain catastrophizing who underwent KA. Preoperative measures included race/ethnicity status as well as a variety of potential confounders, including socioeconomic status, comorbidity, and bodily pain. Outcome measures were Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function scales as well as performance measures. Linear mixed‐effects models compared outcomes over a 1‐year follow‐up period for African American versus non–African American participants.ResultsWOMAC pain scores differences for African American versus non–African American participants averaged ~2 points in unadjusted analyses and 1–1.5 points in adjusted analyses. In adjusted analyses, follow‐up WOMAC function scores differed by 6 points for African Americans compared to non–African Americans (P = 0.002).ConclusionAfrican Americans generally had worse pain, function, and performance prior to KA and worse scores after surgery, but differences were small and attenuated by ~25–50% after adjustment for potential confounding. Only WOMAC function scores showed clinically important postsurgical differences in adjusted analyses. Clinicians should be aware that after adjustment for potential confounders, African Americans have approximately equivalent outcomes compared to others, with the exception of WOMAC function score.

ObjectiveTo operationalize and report on nationally endorsed rheumatoid arthritis (RA) performance measures (PMs) using health administrative data for British Columbia (BC), Canada.MethodsAll patients with RA in BC ages ≥18 years were identified between January 1, 1997 and December 31, 2009 using health administrative data and followed until December 2014. PMs tested include: the percentage of incident patients with ≥1 rheumatologist visit within 365 days; the percentage of prevalent patients with ≥1 rheumatologist visit per year; the percentage of prevalent patients dispensed disease‐modifying antirheumatic drug (DMARD) therapy; and time from RA diagnosis to DMARD therapy. Measures were reported on patients seen by rheumatologists, and in the total population.ResultsThe cohort included 38,673 incident and 57,922 prevalent RA cases. The percentage of patients seen by a rheumatologist within 365 days increased over time (35% in 2000 to 65% in 2009), while the percentage of RA patients under the care of a rheumatologist seen yearly declined (79% in 2001 to 39% in 2014). The decline was due to decreasing visit rates with increasing follow‐up time rather than calendar effect. The percentage of RA patients dispensed a DMARD was suboptimal over follow‐up (37% in 2014) in the total population but higher (87%) in those under current rheumatologist care. The median time to DMARD in those seen by a rheumatologist improved from 49 days in 2000 to 23 days in 2009, with 34% receiving treatment within the 14‐day benchmark.ConclusionThis study describes the operationalization and reporting of national PMs using administrative data and identifies gaps in care to further examine and address.

Published: March 2020

SummaryThis article addresses the combined estimation issues of parameters and states for multivariable systems in the state‐space form disturbed by colored noises. By utilizing the Kalman filtering principle and the coupling identification concept, we derive a Kalman filtering based partially coupled recursive generalized extended least squares (KF‐PC‐RGELS) algorithm to jointly estimate the parameters and the states. Using the past and the current data in parameter estimation, we propose a Kalman filtering based multi‐innovation partially coupled recursive generalized extended least‐squares algorithm to enhance the parameter estimation accuracy of the KF‐PC‐RGELS algorithm. Finally, a simulation example is provided to test and compare the performance of the proposed algorithms.

Published: March 2020

AbstractEfficient synthesis of optically active N‐fused 1,3‐oxazolidines containing quaternary and tertiary stereocenters was achieved via Pd‐catalyzed asymmetric (3+2) cycloadditions of sulfamate‐derived cyclic imines and vinylethylene carbonates. Using a chiral phosphoramidite ligand, the cycloadditions proceeded effectively providing sulfamidate‐fused 1,3‐oxazolidines in high yields (up to 96%) with stereoselectivities (up to 25:1 dr; >99% ee). Additionally, the scale‐up reaction and further transformations of the product were also achieved demonstrating the synthetic utility toward the construction of useful heterocycles such as chiral oxazoline bearing a quaternary stereocenter.magnified image

Published: March 2020

AbstractAn iron‐mediated ring‐opening and rearrangement cascade from 4‐alkenylisoxazoles to polysubstituted pyrroles is described. The cascade reaction conditions are compatible with a variety of functional groups, including ketones, esters, amides, and aryl halides. High reactivity is maintained even if the reaction scale is expanded to 0.5 grams. It is the first iron‐catalyzed rearrangement of 4‐alkenylisoxazoles to pyrroles that is independent of the presence of the alkoxy or amino group at position 5 of the isoxazole substrates. A plausible mechanism of the iron‐mediated cascade reaction is proposed.magnified image
Is selfing a reproductive assurance promoting polyploid establishment? Reduced fitness, leaky self‐incompatibility and lower inbreeding depression in neotetraploids
Authors: Siopa Catarina , Dias Maria C. , Castro Mariana , Loureiro João , Castro Sílvia 
Published: March 2020

PremiseNewly formed polyploids face significant obstacles to persistence and population establishment because of fitness costs of intercytotype mating. Selfing provides the opportunity to escape mate limitation, enabling production of new individuals and increasing the likelihood of fixation of new polyploid lineages. Still, association between self‐compatibility and polyploidy is not always clear. We compared self‐incompatibility and inbreeding depression in neotetraploids and their diploid progenitor to explore the direct effects of whole genome duplications on self‐incompatibility and the implications of ploidy‐driven changes for polyploid establishment.MethodsOutcross and self‐pollinations were performed in diploids and synthetic neotetraploids ofJasione maritimavar.maritima, and reproductive success was measured through fruit and seed production and seed germination. Self‐ and outcross offspring were grown under controlled conditions, and plant performance was measured through several fitness parameters.ResultsNeotetraploids showed an overall lower performance than diploids. Reproductive success was negatively affected by selfing in both cytotypes. However, greater variation in the expression of self‐incompatibility was observed in neotetraploids; additionally, developmental and physiological parameters were not affected by selfing on neotetraploids, with an overall similar fitness of outcrossed and selfed individuals, resulting in lower inbreeding depression indexes.ConclusionsNeotetraploids might have benefited from selfing at initial stages after their formation. Genome duplications resulted in leaky self‐incompatibility, enabling the production of offspring under minority cytotype disadvantage with similar fitness as outcrossed offspring. Our results support theoretical assumptions that selfing might be important for neopolyploid establishment, although changes in self‐incompatibility might not be abrupt.
