Aims: This study aimed to provide more information about the influence of Coronavirus Disease2019 (COVID-19) on infected individuals. The symptoms, conditions, and treatments used may be served as important clues to find out potential medications.
Materials & Methods: Various current papers were reviewed, and the findings were summarized. In addition, other diseases such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), which have similar causes or symptoms in patients, were investigated.
Findings: The most common symptoms in infected patients were fever (98%), dry cough (76%), and dyspnoea (55%). Mechanical ventilation was the main supportive treatment for ICU patients, and the mortality rate of patients with chronic diseases in the intensive care unit (ICU) was high (55%). The virus is highly contagious compared to the previous Betacoronaviruses causing epidemic, but its mortality rate is lower so that most of the infected patients studied had minor symptoms or were asymptomatic. Several treatments, such as antiviral agents and antimalarial drugs, are presently being proposed and tested, but none have yet been proven to be effective.
Conclusions: Seniors and patients with chronic diseases are at higher risk of COVID-19 induced severe consequences and mortality. Currently, supportive treatment is the mainstay for severely ill patients.

Aims: This study aimed to assess the long-term effect of SBY on the academic performance of adolescents and their gender.
Materials & Methods: Repeated measure design using purposive sampling was adopted and 324 adolescent boys and girls practicing Superbrain Yoga for three years from Mysuru District, India were involved in the study. Academic scores of adolescents from 2013 to 2016 were analyzed using Repeated Measure ANOVA by SPSS 21.
Findings: A significant increase in academic scores of adolescents in their performance (F=168.324, p=0.001) was noticed. Girls outperformed boys in Science (F=5.263, p=0.006, η_p²=0.02), second language (F=5.832, p=.004, η_p²=.02), and total performance (F=4.534, p=0.014, η_p²=0.02) with a  minimal effect size.
Conclusion: The long-term practice of Superbrain Yoga showed a positive impact on academic performance among adolescents and the gender difference in academic performance is found minimal. The cognitive enhancement practice of SBY can be implemented in educational settings.

The objectives of the present study were to evaluate spring wheat recombinant inbred lines (RILs) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (PCA) for spot blotch resistance and yield components at BHU Agricultural Research Farm during 2010-2011. Grain yield per plot was significantly and positively associated with biomass, 1,000-grain weight, harvest index, chlorophyll content, and grains per spike at genotypic level. The line 65 exhibited lowest mean of AUDPC value (632) indicating its potential as resistant parent. Cluster analysis grouped all the 324 spring wheat lines into 19 clusters using Ward’s method. Extreme divergence was observed among clusters. By using D²-statistics, the highest inter cluster distance (584.72) was found between Clusters VIII and XIX. Cluster VIII recorded highest mean values for chlorophyll content, peduncle length, bio-mass, grains per spike, 1000-grain weight and grain yield. The major contributing trait towards genetic divergence was found to be AUDPC (60.36%). First 5 principal components (PC1, PC2, PC3, PC4 and PC5) accounted for proportionate values of 20.66, 17.96, 15.07, 8.28, and 7.38%, respectively, contributing 69.35% of the total variability. The second PCs had high positive PC value for plant height, biomass, and 1,000-grain weight. The breeding objectives of the present experiment was to identify genetically diverse wheat spot blotch resistant RILs for developing high yielding spot blotch resistant cultivars especially adopted to south Asia in future breeding programs.

Brassica juncea L. is an important oilseed crop which occupies premier position in Indian agriculture. Developing high yielding genotypes has been a major breeding objective in Indian mustard. Present study was conducted at Directorate of Rapeseed-Mustard Research, India, during 2010-2013 to determine General combining ability (GCA) and Specific combining ability (SCA) of parental lines and better parent heterosis of 36 crosses of Indian mustard. Parents and F₁ hybrids were evaluated in RCBD with 3 replications. Line×tester analysis involving nine breeding lines and four testers revealed the operation of both additive and non-additive gene actions with predominance of non-additive gene action in controlling yield and contributing traits. Four lines, namely, DRMR 2243, DRMR 2341, DRMR 2486, DRMR 2613, and one tester, NRCHB 101, were adjudged the best general combiner possessing highly significant positive GCA effects for seed yield and yield contributing traits. Significant SCA effects for seed yield, 1000-seed weight, oil content, and other attributing traits in desirable direction were recorded in a series of hybrids and a close association between SCA effects and heterosis was observed amongst the best hybrids identified on the basis of SCA effects. Hybrids DRMR 2243/NRCHB 101, DRMR 2269/NRCHB 101, DRMR 2326/NRCHB 101, DRMR 2341/NRCDR 2, DRMR 2398/NRCHB 101, DRMR 2486/Ashirwad and DRMR 2613/NRCDR 2 exhibited highest magnitude of better parent heterosis with highly significant SCA effects and higher per se performance for seed yield. The high yielding crosses may be exploited for developing superior genotypes and the parents involved may be converted to well adapted cytoplasmic male sterile or restorer lines.

Information and Communication Technology (ICT) is one of the emerging driving forces to disseminate the agricultural knowledge. Skilled extension personnel can grab these opportunities for the diffusion of agricultural technologies to farming community. Therefore, the present investigation measures E-skills among agricultural experts of Krishi Vigyan Kendras (KVKs) — Farm Science Centers in Rajasthan and Gujarat states of India. Data were solicited from 87 proportionately selected agricultural experts from 29 KVKs. E-skills of experts were measured on 5-point Likert–type scale. The high level of E-skills among agricultural experts were identified in internet browsing, e-mailing, Micro-Soft (MS) Word, MS Power-Point and mobile use for sending the text messages. The agricultural experts’ training on ICTs had a positive and significant relationship with E-skills while experts’ age had a negtive effect. Elementary in use of ICT, analytical use of ICT, use of mobile phone for information communication and use of ICT for mass communication were the major factors that governed the E-skills. The total variance explained by these factors was found 74.88%. Tactical E-skills, informative E-skills, formal E-skills and communicative E-skills were identified as important levels of E-skills in order of their expertise. Hence, the study recommends to encourage the young professionals and to impart more ICT based trainings for improving the E-skills of agricultural experts towards tactical level of E-skills.
