Principal component analysis (PCA) was employed to examine the effect of nutritional and bioactive compounds of legume milk chocolate as well as the sensory to document the extend of variations and their significance with plant sources. PCA identified eight significant principle components, that reduce the size of the variables into one principal component in physiochemical analysis interpreting 73.5% of the total variability with/and 78.6% of total variability explained in sensory evaluation. Score plot indicates that Double Bean milk chocolate in-corporated with MOL and CML in nutritional profile have high positive correlations. In nutritional evaluation, carbohydrates and fat content shows negative/minimal correlations whereas no negative correlations were found in sensory evaluation which implies every sensorial variable had high correlation with each other.

Whole wheat flour is employed to prepare an unleavened flat-baked chapati product. The majority of people in Asian communities residing all over the world and the Indian subcontinent consume chapati as a traditional staple food. There is an increase in demand for ready-to-eat chapatis due to changes in lifestyle, so this study was initiated to increase the shelf-life of chapatis using selected plant samples through optimization. The optimized dough was seen to have a good leavening and soft texture with no change in their appearance, order, or taste. The spoilage of the prepared and stored chapattis was monitored. At the conclusion of the 20 trials, the range of shelf-life obtained was between 14 to 16 days. On studying the goodness of fit statistics in the model used for the optimization based on the low s value (0.3717), there is a better description of the response. 97.94% R2 value was obtained with consideration of the response describing the fitness of the model. Similarly, its right and it determines adjacent R2 value, and predicted R2 value was not substantially less than the R2 value making the model fit. On encoding the values 0.6625 for turmeric, 0.6625 for the sweet flag, and 0.7305 for tea powders can be used to obtain the maximized shelf-life of 16 days.

The purpose of the current study was to determine the total phenolic and flavonoid content and total antioxidant activity of the Curcuma longa, Acorus calamus, and Camellia sinensis ethanolic extracts and their free radical scavenging activity. The study concluded that the Curcuma longa, Acorus calamus, and Camellia sinensis ethanolic extracts have a good source of phenolics, flavonoids, and antioxidant sources in turn which opens the high possibility of the extracts being used as food preservatives. The DPPH assay for scavenging free radicals showed that the IC50 value was above 123% of Curcuma longa ethanolic extract, 129.9% μg/ml of Acorus calamus ethanolic extract and 25% of Camellia sinensis ethanolic extracts shows very strong inhibition of the free radicals. Thus, comparing the DPPH assay for scavenging free radicals of Curcuma longa, Acorus calamus and Camellia sinensis ethanolic extracts with the positive control ascorbic acid, Curcuma longa and Camellia sinensis ethanolic extracts showed strong inhibition of the free radicals.

In this editorial, an Associate Editor-in-Chief of the Journal of Palaeogeography(JoP) reminisces his publication experience in JoP during the period 2014-2024. 1) During a period of nine years, he contributed eight review articles, three discussions, two replies, one book review, one glossary, and one tribute to the first Editor-in-Chief Prof. Zeng-Zhao Feng. His contributions totaled 534 printed pages. 2) His contributions examined 19 different domains, such as landslides, submarine fans, seismites, SSDS, hyperpycnites, rivers,etc. 3) His contributions coincided with the formative years of JoP. 4) The impact of his articles is evident from the Stats published by ResearchGate. For example, his review article “The Landslide Problem” has reached11,611 Reads and 186 Citations after nine years of publication in 2015. 5) In 2023, the CNKI(China National Knowledge Infrastructure) recognized his article “Submarine fans: a critical retrospective(1950-2015)” as the Top-1% most-highly cited publications in the Journal of Palaeogeography published during a 10-year survey period: 2012-2022. 6) He was inducted as a Founding Member of the International Society of Palaeogeography(ISP) at Changping District of China University of Petroleum(Beijing), Beijing on July 16, 2022. 7) His JoP editorship during the past 10 years has been the most challenging, inspiring, and rewarding experience of his global scientific journey spanning over six decades(1962-2024).

Enzyme inhibition therapy uses specific molecules to inhibit enzyme activity, targeting disease-related enzymes in medical treatments like cancer treatment and infectious disease management. Different types of inhibitors, competitive and non-competitive, bind to different sites and alter enzyme function. The success of this therapy depends on the inhibitor’s specificity and delivery to the target site. Further research could lead to more effective treatments. Nowadays, the majority of medications are enzyme inhibitors and are in the clinical or pre-clinical stages of drug development. Enzyme inhibitors are often prescribed medications for a variety of illnesses, including neurological problems. There is only symptomatic therapy available for many neurological conditions, particularly neuro-degenerative disorders, as opposed to therapy based on knowledge of the underlying mechanisms of these diseases. Enzyme inhibitors are useful as they block the function of certain enzymes whose aberrant activity could be contributing to the illness. They also alleviate the symptoms and stop the disease’s progression. This review discusses the mechanism of action of several enzyme inhibitors that have been prescribed as medications for neurological illnesses as well as some that are still in research stages.
