Cocos Nucifera's Husk Smoke as A Hypoxia Inducer and Developmental Limiter in Drosophila Melanogaster See

Smoke that includes Particulate matter (PM), Carbon monoxide (CO), Sulfur dioxide (SO2), and nitrogen dioxide (NO2), have a substantial negative impact on human health. PM, which can vary from tiny dust to coarse particles, enters the respiratory system and reduces the amount of oxygen taken in by the lungs, leading to hypoxia. Transcription factors called HIFs stimulate genes that help the cells to adjust to hypoxia. Despite its evolutionary separation from mammals, Drosophila melanogaster r...

Targeting Alpha-Toxin: Exploring Flavonoid-Based Strategies Against Clostridium perfringens Reservoirs in Insects See

Insects that thrive in decaying organic matter often act as hidden reservoirs of Clostridium perfringens, carrying the bacterium within their gut microbiota and amplifying its presence in the environment. This ecological relationship enables the dissemination of C. perfringens, particularly its biotype A strains, which produce phospholipase C (Cp-PLC), also known as alpha-toxin. Alpha-toxin is a key virulence factor, disrupting critical signaling pathways in endothelial cells, platelets, and ...

Exploration of The Effect of Plant α-Amylase Inhibitors On Starch Metabolism in Insect Midgut for Pest Control See

Plant α-amylase inhibitors are proteins naturally produced by plants as part of their defense mechanisms against herbivorous insects. These inhibitors target α-amylase enzymes, which are critical for starch digestion in the insect gut, disrupting their ability to utilize starch as an energy source. This interference leads to reduced growth, development, and survival of pest species. In the context of pest control, plant α-amylase inhibitors present a promising avenue for sustainable and eco-f...

Little Magazine as Counter-archive: Notes on Pedagogy and Print Culture of India See

The culture of little magazines in India came into being with the publication of Sabuj Patra in 1914 and became popular in other Indian languages in the 1950s. These “noncommercial” and ephemeral presses not only created the “modern” literary canon, which was chiefly “non-conformist”, but also defamiliarized the notion of the “text” through its material discontinuity. Little magazines in India served as the counter site of “new” literary movements and “unheard voices” from the margin. Thus, l...

Assessment of Coal Pillar Strength under the Influence of Multilayer Weak Bedding Planes Employing Analytical and Numerical Simulation Studies See

Efficient coal extraction from underground mines is largely dependent on the stability of coal pillars, especially in the presence of geological discontinuities that weaken their strength. In Indian coalfields, traditional empirical formulas for pillar strength often neglect these discontinuities, focusing instead on pillar dimensions and coal strength. This study employs numerical simulations to evaluate the impact of multilayer weak bedding planes, placed at various positions within the pil...

The re-emergence of multidisciplinary studies circles back to the cha...

Decolonizing Nature: Co-existence, Harmony, and the Vedic Tradition in Aranyaka: Book of the Forest See

In the present capitalist world system, the human approach to nature is utilitarian: it has been reduced to mere resources whose significance is equivalent to the surplus value it produces for the betterment of a section of mankind. This mechanistic view and commodification of nature is traced back to Western reductionist philosophies that deny agency to nature and the non-human and place humans at the top of the hierarchical ‘Great Chain of Being.’ The non-human turn in the Humanities, inspi...
