Forming of simple components of silicon carbide, Silicon nitride and silicon by slip casting methods
The slip casting studies on well optimised slips of Sic, Si3N 4 and silicon have been applied to fabricate some components with complicated shapes eg. after burner catalytic ignitor housings, super charger stator rings etc. The green densities of slip cast bodies of Sic, Si3N4 and silicon slips ranges from 50 to 60 of theoretical value, indicating that good compacts can be obtained by the slip casting procedure by using these optimised slips
Time to sense biofield (Prana) experiences between hands: A preliminary single blinded randomized placebo controlled trial [version 4; peer review: 3 approved]
Aims There is minimal research on the duration of biofield experiences. This preliminary study used the experiential learning practice of Master Choa Kok Suis hands sensitisation to determine the duration to experience biofield sensations in between hands and to find the relationship between learning style preferences and biofield sensations. Methods This randomized placebo controlled, single blinded trial included 88 male and female pre-service teachers, aged 22.8±1.2 years. Participants completed a ruler drop test for reaction time, and Six Letter Cancellation test for measuring attention, learning style questionnaire for preferred method of learning, before randomization. The experimental (hands facing each other as introduced by Master Choa Kok Sui) and sham (hands facing opposite) groups practiced hands sensitisation. A semi-structured questionnaire was provided to gather information about biofield sensations and the time it took to experience these sensations between the hands. Results All (N=44) the participants in the experimental group and 13 participants in the sham group reported experiencing biofield sensations. A significant difference was noticed in experiencing magnetic (X2 = 38.247, p ≤ .001), physical sensations of energy (X2 = 12.02, p ≤ .001) and pain (X2 = 62.259, p ≤ .001) among the experimental and sham group . In the experimental group, the average time taken to first experience magnetic sensation, other biofield sensations and temperature variation was 34.84±12.97seconds, 40.28±20.96 seconds and 42.50±19.79 seconds, respectively. Minimum time taken to first experience biofield sensation was 5 seconds and lasted up to study duration of 120 seconds. There was no correlation found between reaction time, sustained attention, and the time needed to experience biofield sensations. Conclusions This study highlights importance of Master Choa Kok Sui hand sensitization in controlled setting revealing differences in experiences of various biofield sensations, showing valuable time-related insights and variability of sensation based on preferred learning

Rickettsial neglected zoonoses: prevalence of scrub typhus at central Karnataka
Background: Fever of unknown Origin (FUO) has many multiple causes such as enteric fever, malaria, dengue, tuberculosis, brucellosis. But scrub typhus is less known cause in Indian scenario. The present study reports the prevalence of scrub typhus at central Karnataka and compares the sensitivity and specificity of Weil-Felix test and the IgM ELISA in the detection of infection.Methods: 368 serum samples of FUO cases were collected. Weil-Felix test was performed and also analyzed for IgM antibodies to Orienta tsutsugamushi by IgM ELISA test along with haematological and biochemical investigations.Results: Out of 368 patients of fever of unknown origin, 94 cases were positive by OXK antigens by Weil Felix test and 61 were positive by ELISA test for ST IgM antibodies. Fever was the most common clinical presentation occurring in ST IgM ELISA positive cases, followed by myalgia in 90.1% cases, headache in 77%, hepatomegaly in 65.5%, splenomegaly in 62.2% and rashes were seen in 29.5% patients. Eschar was seen in 13.1% patients, pneumonia in 3.2% and meningo-encephalitis in 1.6%. Sensitivity and specificity of WFT in relation to IgM ELISA at a titre of 160 was 81.97% and 85.67% respectively.Conclusions: With the growing number of cases detected in India, scrub typhus is fast emerging as a public health threat and also due to limited diagnostics leading to underreporting, Weil Felix test could be used in adjunct with Enzyme-linked immunosorbent assay and blood parameters in the diagnosis of rickettsial diseases
Genetic Dissection of Grain Size Traits Through Genome-Wide Association Study Based on Genic Markers in Rice
Not AvailableGrain size plays a significant role in rice, starting from affecting yield to consumer preference, which is the driving force for deep investigation and improvement of grain size characters. Quantitative inheritance makes these traits complex to breed on account of several alleles contributing to the complete trait expression. We employed genome-wide association study in an association panel of 88 rice genotypes using 142 new candidate gene based SSR (cgSSR) markers, derived from yield-related candidate genes, with the efficient mixed-model association coupled mixed linear model for dissecting complete genetic control of grain size traits. A total of 10 significant associations were identified for four grain size-related characters (grain weight, grain length, grain width, and length-width ratio). Among the identified associations, seven marker trait associations explain more than 10% of the phenotypic variation, indicating major putative QTLs for respective traits. The allelic variations at genes OsBC1L4, SHO1 and OsD2 showed association between 1000-grain weight and grain width, 1000-grain weight and grain length, and grain width and length-width ratio, respectively. The cgSSR markers, associated with corresponding traits, can be utilized for direct allelic selection, while other significantly associated cgSSRs may be utilized for allelic accumulation in the breeding programs or grain size improvement. The new cgSSR markers associated with grain size related characters have a significant impact on practical plant breeding to increase the number of causative alleles for these traits through marker aided rice breeding programs.Not Availabl
Management of Peripheral Arthritis in Patients With Psoriatic Arthritis: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.
OBJECTIVE
We aimed to compile evidence for the efficacy and safety of therapeutic options for the peripheral arthritis domain of psoriatic arthritis (PsA) for the revised 2021 Group in Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations.
METHODS
A working group consisting of clinicians and patient research partners was convened. We reviewed the evidence from new randomized controlled trials (RCTs) for PsA treatment from February 19, 2013, to August 28, 2020. We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)-informed approach to derive evidence for the classes of therapeutic options for 3 patient groups: (1) naïve to treatment, (2) inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and (3) inadequate response to biologic DMARDs (bDMARDs). Recommendations were derived through consensus meetings.
RESULTS
The evidence review included 69 RCTs. We derived GRADE evidence for each class of therapeutic options and achieved consensus for the recommendations. For patients naïve to treatment, the working group strongly recommends csDMARDs (methotrexate, sulfasalazine, leflunomide) and phosphodiesterase 4 inhibitors, and emphasizes regular assessment and early escalation to achieve treatment target. bDMARDs (tumor necrosis factor inhibitors [TNFi], interleukin 17 inhibitors [IL-17i], IL-12/23i, IL-23i) and Janus kinase inhibitors (JAKi) are also strongly recommended. For patients with inadequate response to csDMARDs, we strongly recommend TNFi, IL-17i, IL-12/23i, IL-23i, and JAKi. For those who had prior experience with bDMARDs, we strongly recommend a second TNFi, IL-17i, IL-23i, and JAKi. The evidence supporting nonpharmacological interventions was very low. An expert panel conditionally recommends adequate physical activity, smoking cessation, and diet to control weight gain.
CONCLUSION
Evidence supporting optimal therapy for the peripheral arthritis domain of PsA was compiled for the revised 2021 GRAPPA treatment recommendations

Study of Antidepressant Activity of Garcinia indica(Kokum) Fruit Rind in Wistar Albino Rats
BACKGROUND Depression is a mental disorder which is treatable but detected less often in primary healthcare settings. Therefore, there is a need for an effective treatment strategy for the management of depression. Garcinia indica (Thouars) Choisy is a slender evergreen tree. An invitro animal study has shown that its phytochemical constituent, hydroxy citric acid has the ability to increase serotonin levels in the brain. Hence, the objective of the study was to evaluate the antidepressant activity of ethanolic extract of Garcinia indica fruit rind in animal models of depression and compare it with control and standard drugs, imipramine, and fluoxetine. METHODS The study was conducted on Wistar albino rats of either sex. The animals were grouped into five, containing six animals in each group. Control (0.1 % carboxymethylcellulose, 10ml/kg), ethanolic extract of Garcinia indica (GIEE1) – 250mg/kg, ethanolic extract of Garcinia indica (GIEE2) – 500mg/kg, Standard1 - Imipramine – 10mg/kg ( Forced Swim test only) and Standard2 - Fluoxetine – 20mg/kg (Tail suspension test only). Drugs were administered for 14 days and antidepressant activity was evaluated on the 14th day after one hour of drug administration using two models - Forced swim test and tail suspension test. Results were tabulated as mean ± SEM (standard error of mean). One-way analysis of variance (ANOVA) followed by Tukey Kramer test was used to interpret the statistical significance. RESULTS The period of immobility was obtained as 21.83 ± 1.44 and14.66 ± 2.74 in forced swim test and 36.8 ± 1.01 and 14.3 ± 0.954 in tail suspension test in GIEE1 and GIEE2 treated groups respectively, which was significantly less compared to control. CONCLUSIONS Garcinia indica has significant antidepressant activity compared to the control. KEY WORDS Antidepressant, Garcinia indica, Fruit Rind, Wistar Albino Rats</jats:p
