Methodology: Ten marigold genotypes were evaluated under controlled polyhouse and natural cold stress conditions across two growing seasons. High-throughput plant phenotyping utilizing RGB, near-infrared, and thermal imaging quantified key traits including morphological characteristics (via RGB), tissue water content (via near-infrared), and thermal regulation (via thermal imaging), complemented by targeted physiological and biochemical analyses. Results: Significant genotypic variation was observed, as cold stress caused 70.7% reduction in plant area and 24.3% decrease in the photosynthetic rate. Genotype Af./W-4 exhibited superior cold tolerance through enhanced photosynthetic maintenance, minimal reductions in greenness (4.4%), membrane stability (11%), and photosynthetic rate (14.2%), followed by genotypes PB and Af./W-6. Multivariate analysis indicated that key determinants of cold stress performance include traits like plant area, caliper length, greenness, and photosynthetic rate. Interpretation: Integration of non-invasive imaging with biochemical analysis successfully differentiated cold-tolerant from the susceptible genotypes. This comprehensive approach provides an efficient screening methodology for identifying climate-resilient genotypes in ornamental crops, potentially accelerating cold-tolerant genotype development for sustainable floriculture production.

Methodology: Cepacian was extracted from B. cepacia followed by isolation and identification of potent cepacian utilizing bacteria based on planktonic growth using cepacian as sole carbon source. Effective lyase activity (responsible for cepacian breakdown) and anti-biofilm activity of potent isolate against B. cepacia was determined. Effect of biofilm disintegration on antibiotic penetration into biofilm was detected. Lastly, inhibition of biofilm formation by crude lyase preparation of the isolate inside an external medical device was detected. Results: Cytobacillus sp. strain Dbc1 was the most potent cepacian degrading bacteria which showed significant lyase activity and reduced total biomass of both newly formed and pre-formed biofilm of B. cepacia. Cepacian degradation potentiated chloramphenicol penetration within pre-formed biofilm leading to cell mortality in B. cepacia. Cytobacillus sp. strain Dbc1significantly reduced total biomass of established biofilm inside nasal oxygen catheter.

Methodology: The nuts of 32 almond genotypes were collected from the experimental farm of ICAR-CITH, Srinagar. Using a Soxhlet fat apparatus and 100ml of petroleum ether as a solvent, almond oil was extracted from 5 g of ground kernel. The fatty acid content of almond oil was analyzed by GC 30 (Perkin Elmer Autosystem XL) equipped with a CP-Wax 52 CB column (Varian Inc.) (50 x 0.25 mm, 0.2 μm). Results: The total oil content in these genotypes ranged between 41.82% (CITH-A-21) and 51.86% (Waris). The major fatty acids found were oleic acid (53.70-80.81%), linoleic acid (11.63-36.88%), and palmitic acid (5.19-8.13%). Stearic acid (1.01-2.53%) was estimated at a lower proportion, while α-linolenic acid was found in trace amounts (0.05-0.18%). The oleic: linoleic acid ratio varied from 1.46 (CITH-A-21) to 6.95 (CITH-A-06), conversely the highest (115.42) and lowest (93.96) iodine values were recorded in CITH-A-21 and CITH-A-06, respectively. The lowest content of saturated fatty acids (6.32%) and the highest content of unsaturated fatty acids (93.69%) were found in CITH-A-17 whereas contrasting results were observed in Nonpareil. The highest monounsaturated fatty acids (80.81%) and lowest polyunsaturated fatty acids (11.71%) were found in CITH-A-6. Oleic acid content was negatively correlated with linoleic acid (r = -1.00), palmitic acid (r = -0.67) and stearic acid (r = -0.68). Principal component analysis indicated that among the fatty acids, the oleic acid, linoleic acid, and Oleic/Linoleic ratio were largely responsible for the separation on the PC 1. Among the different almond genotypes, CITH-A-17 and CITH-A-06 were found to be promising in terms of fatty acid composition. Interpretation: The present study identified the genotypes with a high Oleic/Linoleic acid ratio, which is important for crop improvement programme and commercialization of these genotypes.

Traditionally these studies are performed using suitable animal (in vivo) models. There was a time when toxicologists/pharmacologists were searching models alternate to animal toxicity testing (Doke and Dhawale, 2015). Improved cell culture techniques, knowledge on stem cells and other microbiological systems led to the development of in vitro toxicology. It was soon followed by DNA chips, micro fluidics, in silico toxicology , toxicogenomics and computational toxicology. Several platforms are now discussing machine learning (ML) and artificial intelligence (AI) together as future tools of computational toxicology. For decades, quantitative structure-activity relationship (QSAR) methods have been employed to study the effects of drugs/chemicals (Cai et al., 2022). However, AI methods for toxicity assessment ranging from ADMEtox to AI4TOX provide evidence to the immense potential of AI. Intriguingly, a few problems between theoretical developments and practice of AI by end users have been recognized. AI is now being employed in cancer care. According to WHO (2022), cancer is responsible for 9.3 million deaths per year. AI is being used for cancer grading, classification, follow up services and diagnostic accuracy. However, certain limitations viz. testing, validation, certification and auditing need to be addressed (Cabral et al., (2023). Potential of AI in diabetic care and management has recently been recognized. The huge burden of diabetic patients in India can be managed through AI tools. Diabetic risk can be predicted using genomic data, to diagnose diabetes using EHR data and to identify diabetes related complications i.e. retinopathy and nephropathy (Singhla et al., 2019). Application of AI in the management of cardiovascular diseases like myocardial infarction has been highlighted with special reference to Chinese medicine (Chen et al., 2022). There exists experimental evidence that AI tools can be used to assess, monitor and manage Parkinsons' disease (Bounsall et al., 2023). Perspectives of the application of AI in complimentary and alternative medicine were reviewed by Chu et al. (2022). Several regulatory agencies are now adopting the concept of 3R ie., replacement, reduction and refinement of animal testing (EU REACH/3R principles; Toxicology 21 of U.S. Government) ( Maestri, 2021).The application of AI in clinical toxicology through converging data resources, algorithms, real world information from sensors and health records has also been discussed (Sinha et al. 2021). Plausibility of toxicity prediction using AI tools was recently reviewed by Santin et al. (2021).
