Energy Expenditure and Nutritional Status of Sailors and Submarine Crew of the Indian Navy
Nutritional requirements of sailors and submariners are different from those of ground forces as they work under confined environment as well as due to logistic constraints of cooking and storage of food. Study was conducted for a period of three months at Eastern Naval Command to evaluate nutrient requirements, nutritional status of Indian Navy personnel and adequacy of the existing ration scales. The study volunteers were from crew of two warships (n = 35) and submariners (n = 20) who were attached to their mother ships during time of data collection and offshore during rest of the period. Energy expenditure, nutrient intake, level of nutrients in body, and urinary excretion were measured along with changes in body composition. All variables were analysed before and after three months of nutritional monitoring. Energy expenditure at ship was in the range of 2449-4907 kcal/day with a mean of 3313 + 578 kcal/day, while in the case of submariners, it was 3168 + 282 (2606-3907) kcal/day. The energy intake in the case of sailors and submariners was not different either on shore establishment or at ship. Energy intake was found to be 3518 + 286 kcal/day. The energy contribution from carbohydrates, fats, and protein was 59.9 per cent, 27.8 per cent and 12.3 per cent, respectively. No sign and symptoms of any nutritional deficiency were observed either initially or after three months. Status of micronutrients present in their blood and in their urinary excretions along with body composition were maintained, indicating adequacy of existing ration scales of Indian Navy.Defence Science Journal, 2011, 61(6), pp.540-544, DOI:http://dx.doi.org/10.14429/dsj.61.93
Saliency mapping in the optic tectum and its relationship to habituation
Habituation of the orienting response has long served as a model system for studying fundamental psychological phenomena such as learning, attention, decisions, and surprise. In this article, we review an emerging hypothesis that the evolutionary role of the superior colliculus (SC) in mammals or its homolog in birds, the optic tectum (OT), is to select the most salient target and send this information to the appropriate brain regions to control the body and brain orienting responses. Recent studies have begun to reveal mechanisms of how saliency is computed in the OT/SC, demonstrating a striking similarity between mammals and birds. The saliency of a target can be determined by how different it is from the surrounding objects, by how different it is from its history (that is habituation) and by how relevant it is for the task at hand. Here, we will first review evidence, mostly from primates and barn owls, that all three types of saliency computations are linked in the OT/SC. We will then focus more on neural adaptation in the OT and its possible link to temporal saliency and habituation
Responses to Pop-Out Stimuli in the Barn Owl's Optic Tectum Can Emerge through Stimulus-Specific Adaptation
A Systematic Review on Panchakarma-Based Ayurveda Treatment in Janu Sandhigata Vata
Janu Sandhigata Vata or knee osteoarthritis (KOA) causes chronic pain, stiffness, immobility and affects daily life. Panchakarma-based Ayurvedic treatment is popular in arthritis. The present study has done a systematic review on effectiveness and safety of panchakarma-based treatment in chronic KOA. The study searched for double-arm randomized comparative trials (RCoTs) with human subjects (age ≥ 18 years) explicitly diagnosed with KOA in fourteen electronic databases including MEDLINE, PubMed Central, Cochrane, Ayush Research Portal for indexed research and clinical trials published till September 30, 2022. At least one patient-centred primary outcome, namely pain, physical function, global improvement according to OMERACT III were eligible. Risk-of-bias analysis was done independently by the two authors using the revised Cochrane risk-of-bias tool for randomized trials. Effect size as standardized mean differences between treatments were estimated for pain and stiffness. The inclusion criteria screened 10 RCoTs. The RCoT which used manual therapies in a multimodal ayurvedic care against conventional care had overall low risk of bias. Remaining 9 RCoTs compared the treatment outcomes of different panchakarma-based treatment with and without pharmacological interventions. In 3 RCoTs, effect size on pain and stiffness were medium to large and significant (P<0.01). Only 3 RCTs reported safety concerns and no serious adverse outcomes related to intervention were noted. Sudation techniques and enema therapy used as standalone or in multimodal ayurvedic care showed benefit in KOA. Future studies on the long-term efficacy and safety goals aligned to psychosomatic record of patients are required for personalized Ayurveda multimodal care.
Ongoing activity in the optic tectum is correlated on a trial-by-trial basis with the pupil dilation response
DataSheet_1_Performance appraisal of Trichoderma viride based novel tablet and powder formulations for management of Fusarium wilt disease in chickpea.docx
In developing a Trichoderma viride-based biocontrol program for Fusarium wilt disease in chickpea, the choice of the quality formulation is imperative. In the present study, two types of formulations i.e. powder for seed treatment (TvP) and tablet for direct application (TvT), employing T. viride as the biocontrol agent, were evaluated for their ability to control chickpea wilt under field conditions at three dosages i.e. recommended (RD), double of recommended (DD) and half of recommended (1/2 RD). A screening study for the antagonistic fungi strains based on volatile and non-volatile bioassays revealed that T. viride ITCC 7764 has the most potential among the five strains tested (ITCC 6889, ITCC 7204, ITCC 7764, ITCC 7847, ITCC 8276), which was then used to develop the TvP and TvT formulations. Gas Chromatography-Mass Spectrometry (GC-MS) analysis of volatile organic compounds (VOCs) of T. viride strain confirmed the highest abundance of compositions comprising octan-3-one (13.92%), 3-octanol (10.57%), and 1-octen-3-ol (9.40%) in the most potential T. viride 7764. Further Physico-chemical characterization by standard Collaborative International Pesticides Analytical Council (CIPAC) methods revealed the optimized TvP formulation to be free flowing at pH 6.50, with a density of 0.732 g cm-3. The TvT formulation showed a pH value of 7.16 and density of 0.0017 g cm-3 for a complete disintegration time of 22.5 min. The biocontrol potential of TvP formulation was found to be superior to that of TvT formulation in terms of both seed germination and wilt incidence in chickpea under field conditions. However, both the developed formulations (TvP and TvT) expressed greater bioefficacy compared to the synthetic fungicide (Carbendazim 50% WP) and the conventional talc-based formulation. Further research should be carried out on the compatibility of the developed products with other agrochemicals of synthetic or natural origin to develop an integrated disease management (IDM) schedule in chickpea.</p
