Abstract	Green hydrogen is gaining popularity as a clean fuel, and India is one of the countries that is exploring its potential. The paper analyzes the factors contributing to the adoption of green hydrogen in India. The government’s policies to encourage usage of clean energy and cut down carbon dioxide emissions are a key factor driving the adoption of green hydrogen in India. Additionally, with the accessibility of renewable energy resources, the growing demand for hydrogen in various industrial applications, and the development of supportive infrastructure and policies are also contributing to the expansion of the green hydrogen sector. The study did a comprehensive literature survey to determine 21 variables that contribute to the green hydrogen development in India, which have been categorized under 4 blocks, namely, varied incentives, government support measures, R&D landscape, and green mandate. These blocks can be utilized to articulate and upgrade the green hydrogen policy.

Abstract	Background: Fixed drug reaction (FDE) is characterized by the development of well-circumscribed, round, erythematous macules and plaques on cutaneous or mucosal surface following ingestion of the offending drug. Aim and objectives: To study the etiological agents responsible for FDE and to study the clinical patterns of FDE due to different drugs. Materials and methods: It was a hospital-based observational cross-sectional clinical study. The study period was 24 months. Fifty patients were included. The study was done after a literature search, hypothesis generation, protocol write-up, ethical submission, ethical clearance, patient enrollment, data collection, data analysis, and research. The patients were selected on the basis of the Naranjo scoring system. The patients with a history of combination drug intake were not included in the study. Results: A total of 0.11% patients presented with FDE in the study period. Out of them, 52% of the patients belonged to 20-39 years age group, having sex ratio of 1.6:1. About 64% of the patients presented with multiple lesions, whereas 36% had a single lesion. A total of 46% patients presented with first episode and 54% had recurrent episodes. The mean time intervals of first and subsequent episodes were 6.5 days and 4.3 hours, respectively. Also, 16% patients had a history of herpes infection. Extremities were more affected followed by trunk and mucosa. Fluoroquinolones were the most common etiological agent found in 56% patients having cutaneous (48%) and mucosal lesions (14%). The most common drug was norfloxacin (36%) followed by both paracetamol (12%) and metronidazole (12%). Fluoroquinolones were the most common drugs implicated in bullous lesions and generalized bullous FDE. Limitations: The study population was small and the study was for a limited period of time. Conclusion: The patient should be aware of the offending drug and opt for any alternative agent after visiting the physician.

Abstract	Background: Adverse drug reactions (ADRs) are major problems in the drug therapy. Cutaneous adverse drug reactions (CADRs) are the most common ADRs. The pattern of CADRs differs among various drugs. Aims: To record various morphological patterns of CADRs and their causal relationships among patients attending in a tertiary care centre. Materials and methods: An observational, cross-sectional, clinical study was conducted for a duration of one and a half years in a tertiary care centre in eastern India. Patients presenting with suspected CADRs were included if drug identity could be ascertained. Clinical profiling and drug history were recorded, and causality assessment was carried out as per the Naranjo scale. Result: The commonest CADR in our study was fixed drug eruption (FDE) 48.61%, followed by SJS-TEN spectrum 16.66%, maculopapular rash 11.11% and so on. Severe cutaneous adverse drug reactions (SCARs) such as SJS, TEN, SJS-TEN Overlap, AGEP and DRESS accounted for 18 cases (25%). The most common culprit drugs were antimicrobials (54.16%), followed by nonsteroidal anti-inflammatory drugs (15.27%) and anticonvulsants (12.5%). Most of the CADRs were in probable category. Conclusion: The pattern of CADRs and the drugs causing them in our study population are similar to some previous studies but somewhat different from most of the previous Indian studies. The incidence of SCARs was significantly higher than in previous other studies in India and abroad.

Abstract	Psoriasis is a multifactorial, chronic, immune-mediated inflammatory condition. Psoriasis often goes beyond the skin, nails and scalp and involves the eyes (uveitis), joints (arthritis) and several metabolic derangements, as seen in various studies. It is strongly associated with features of the metabolic syndrome (MetS) like hypertension, obesity, dyslipidaemia, type 2 diabetes, insulin resistance and non-alcoholic fatty liver disease. Amongst various skin diseases, MetS has the strongest association with psoriasis. The risk of having MetS is almost doubled in patients with psoriasis as compared to healthy individuals. Both conditions share a common pathophysiological background in terms of genetics, inflammatory markers, lifestyle choices, etc. The association of psoriasis with MetS is clinically important as it influences the prognosis, quality of life and choice of treatment. Systemic conventional drugs should be used with caution in such patients, as their long-term use may contribute to metabolic impairment. The treating dermatologist should be aware of such associations and their implications, and a more holistic approach should be taken to manage psoriasis where equal importance is given to lifestyle and dietary modifications and comorbid conditions, in addition to the pharmacological therapy so as to decrease the burden of the disease for both the patient and the health system.

Abstract	Researchers are making all out efforts worldwide, to find a serological marker to monitor the disease severity and/or measure efficacy of the drug. There are many potential molecular targets being investigated as a candidate marker. However, till date there has been no significant breakthrough. Thus, various scoring systems have been devised to evaluate the disease severity in psoriasis. In spite of constant revisions of the scores being currently used, from time to time. None of the scores yet satisfy all the validation criteria desired of an ideal scoring system. And this is partly also because of the fact that the psoriasis has such a huge range of clinical variants. Nevertheless, in the recent past, significant progress has been made in this direction.

Abstract	A strategy of one-pot regioselective cohydrogenation of styrene oxide (STOX) and aryl alkenes (styrene and alpha-methylstyrene) in the presence of aralkyl alcohols (1-phenylethanol and 2-phenyl-2-propanol) is proposed. It would help reduce capital and operational expenditure in the aralkyl hydroperoxide-based 2-phenylethanol (2PEA) manufacturing process. Reactions are performed in a stirred tank reactor in the presence of a 5% Pd/C catalyst. A range of operating conditions are proposed wherein STOX is converted to 2PEA, whereas the aryl alkenes are converted to their corresponding alkylbenzenes. Interestingly, the rate of hydrogenation of STOX is much slower than the rapid hydrogenation of the aryl alkenes. The kinetic model for the reaction is proposed based on the experimental data, and the associated parameters are estimated by nonlinear regression. The apparent activation energy for STOX hydrogenation over the range of operating conditions is calculated as 47.65 kJ mol–¹. The estimated kinetic parameters are apposite for the technocommercial feasibility study and subsequent scaling-up issues of the aralkyl hydroperoxide-based novel scheme of 2PEA production. Based on the observations, conceptual flowsheets for 2PEA manufacturing using cumene hydroperoxide and ethylbenzene hydroperoxide are also proposed.

Abstract	Fish nuggets were prepared with dragon fruit peel powder (1.0, 1.5 and 2.0% w/w) to evaluate its quality and improvement in shelf-life during 15 days storage in a prefabricated solar cooler (5 ± 1 °C). Antioxidative and antimicrobial effects of dragon fruit peel powder in fish model system were also evaluated during storage. Results showed that dragon fruit peel is a good source of dietary fibre (59.8%) and phenolic compounds [65.7 mg Gallic Acid Equivalent (GAE)/100 g of sample] and contained 6.03% protein, 6.14% fat and 4.34% ash. Use of dragon fruit peel powder significantly (p < 0.05) improved the emulsion stability and cooking yield and nuggets with peel powder had lower pH value than control. Fish nuggets with peel powder showed gradual decrease (p < 0.05) in hardness, springiness, cohesiveness, gumminess and chewiness with advancement of storage period. Nuggets with 1.5% dragon fruit peel showed better sensory attributes compared to the others. Dragon fruit peel powder significantly inhibited (p < 0.05) the lipid oxidation and microbial load in fish nuggets during the storage period. So, it can be concluded that dragon fruit peel powder may be used as antioxidant dietary fibre for improved quality and acceptability of fish nuggets in prefabricated solar cooler. 1.5% level of incorporation showed better results in terms of antioxidant activity and better shelf-life of the fish nuggets.
