Abstract

Introduction: The immunogenicity of crude amoebic antigen and its fractions preparedfrom Entamoeba histolytica (NIH:200) was evaluated in experimental animals. Material and Methods: Forty two guinea pigs of either sex free from Entamoebainfection and aged around 3 to 4 weeks were randomly divided into 5 groups. The treatedgroups consisted of 8, 10, 6, and 8 animals and 10 animals served as controls. Crude amoebicextract and its chromatographed fractions were used to immunize the treated animals. All theanimals were assessed for immunity status, challenged with Entamoeba trophozoites andsubsequently examined for lesions of the caecum and liver. Results: Of the 8 animals immunized with crude antigen, one had liver abscess and 5 hadcaecal lesions. None of the 10 animals immunized with fraction I (FI) had hepatic lesions and one had caecal lesions. Both caecal and hepatic lesions were observed in animals immunizedwith FII & FIII. Conclusion: Results show that vaccination with the F1 fraction of Entamoeba histolyticaprovided up to 90% protection against infection. The other fractions and the crude extractprovided less protection.

Abstract

Millets gained a great attention at the global level in 2023 which is celebrated as the "International Year of Millets" to create awareness to eventually promote consumption and production. An attempt is made here to understand the cultivation and production dynamics of millets as influenced by their demand and supply. We also assess challenges and emerging opportunities to make millets more productive, competitive, and relevant to future farming. Millets registered a 60% decline in area and a 200% rise in productivity, but production has remained the same during the last seven decades. The demand of millets decreased as food due to greater incentives (purchasing grain at a pre‐determined price) and policies (distribution of grains to the public at a subsidized rate) in favor of wheat and rice. Millets would play a greater role in future agriculture due to challenges posed by climate change, limited water supply, and reduced agro‐biodiversity. This would need a much greater intensity of investment in millet research and adequate support as extended to wheat and rice. Increased emphasis on their genetic improvement and agronomic management is required to develop cultivars, using new tools and technologies, with high production potential and adequate environmental adaptation to make millets competitive with other crops. Mainstreaming the nutritional traits in millet breeding is also critically important to develop high‐yielding cultivars with improved grain quality traits. Promoting millet consumption would remain the key issue for increasing their demand as food, feed, and industrial raw materials through policies and awareness programs. Strengthening of value chain will help in diversifying agri‐food production system and creating an ecosystem for millet promotion. Core Ideas: There have been significant changes in millet cultivation in India during last seven decades.Millets registered a 60% decline in area and 200% rise in productivity.Production of millets has remained same during last seven decades.Millets would play a greater role in future agriculture due to anticipated challenges posed by climate‐change.Increasing millet productivity and promoting consumption are the key issues to be addressed.

Abstract

In Extended Data Fig. 1 of this Article, the labels ‘Market class’ and ‘Biological status’ were inadvertently swapped. In the corresponding figure legend, “Track 1: Biological status; Track 2: Market class;” should have been “Track 1: Market class; Track 2: Biological status;”. The original Article has been corrected online.

Abstract

Training is essential not only to increase productivity, but also to keep workers of an organization motivated and inspired. In this study, the effectiveness of trainings conducted by Indian Council of Agricultural Research (ICAR) during 2017-18 in which 901 Scientists, 506 Technical, 519 Administrative and 313 Skilled Support Staff (SSS) from 106 ICAR-Institutes across 26 States/UTs participated was assessed by HRM Unit, ICAR HQs, New Delhi during 2018-19. Study revealed that the pooled perceived training effectiveness index (PTEI) was 3.86, referring medium effectiveness of trainings. The mean PTEI score was the highest for SSS (3.94) followed by Administrative staff (3.90). Overall, most of the participants (58.83%) reported medium degree of effectiveness of the training programmes. Behavioural changes and changes in practices as a consequence of exposure to the trainings are evident from the findings. The study revealed that perceived effectiveness was significantly associated with age, gender and duration of training programmes. Some observed constraints by the trainees were inadequate infrastructure at Institutes, sometimes lesser relevancy of few topics and lack of practical exposure. The major suggestions were inclusion of more practical sessions, follow up programmes for trainee-trainer meet, and increasing the duration of the trainings in few cases. The trainings organised by ICAR should continue for all staff categories to bring about desirable changes in competencies.
