Are Petrea volubilis and P. arborea (Verbenaceae) Conspecific? New Insights From Anatomy

ABSTRACT Correct taxonomic identity is crucial in plant taxonomy, especially in the case of practically good species that are considered conspecific due to lack of sufficient reliable data, such as those studied here. Linnaeus in 1753 established the genus Petrea L. with a single...

Trimetallic Cu–Zn–Fe Layered Double Hydroxide Nanocarrier Enabling On-Demand Anticancer Drug Release with Prolonged Therapeutic Windows for Precision Oncology

Clinical oncology faces a critical technological bottleneck driven by the rapid emergence of therapy-resistant tumors. Melanoma, in particular, remains a highly aggressive malignancy with pronounced metastatic potential and poor responsiveness to traditional therapy, signify the...

Genetic divergence and signatures of historical isolation of the traditionally harvested Amolops marmoratus from the Darjeeling Hill Region in the Himalaya Biodiversity Hotspot

BACKGROUND: The Darjeeling Hill Region (DHR) has numerous freshwater bodies, such as hill streams, springs, and temporary water pools. It receives abundant rainfall and has extensive forest cover, which together play vital roles in sustaining frog diversity. Amolops marmoratus is...

Exosomal non-coding RNAs in persistence of cancer stem cells: mechanistic insights and therapeutic opportunities to mitigate risk of recurrence

Exosomal non-coding RNAs (ncRNAs) are recognized as functionally active molecules that mediate communication between the tumor microenvironment (TME) and cancer stem cells (CSCs). While individual studies have reported this crosstalk, an integrated overview of how TME-derived exo...

Leveraging exosomes and lipid nanoparticles based nanomedicine for cervical cancer therapeutics

Cervical cancer (CC) remains a significant global health burden, ranking as the fourth most common cancer among women worldwide. Persistent infection with high-risk human papillomavirus (HPV) is the primary etiological factor, although tumor progression is also influenced by gene...

A new species of Aphanogmus Thomson (Hymenoptera: Ceraphronidae) from India

A new species of Aphanogmus, A. bankebiharii Tyagi, Ghosh and Kumar, is described from India. The species was collected from the Purulia district of West Bengal, India, using yellow pan traps. A detailed description of the new species including male genitalia is provided. Moreove...

Mitogenomic characterization and phylogenetic placement of the mottled wood-owl strix ocellata with gene rearrangement patterns in strigiformes

Abstract Owls (order Strigiformes) represent a highly specialized lineage of nocturnal raptors, within which the genus Strix (family Strigidae) comprises several widely distributed species despite the limited availability of comprehensive mitogenomic data. In this study, the comp...

Regulatory T cells as drivers of CNS remyelination: neuro-immune cross-talk and comparative insights from mammalian and zebrafish models

Demyelination of the Central Nervous System (CNS) is a pathological process that causes the destruction of the myelin sheath, the insulating cover that protects the nerve fibres. This serves as one of the major attributes of numerous neurological disorders, such as Multiple Scler...

Who Benefits? Unveiling the Utilisation Pattern of India’s Janani Suraksha Yojana Program

The Janani Suraksha Yojana (JSY), introduced by the Government of India, aims to reduce maternal and neonatal mortality by encouraging institutional deliveries among economically and socially disadvantaged women. We analyse the distribution of JSY benefits using the concentration...

Anthropocene-Driven Environmental Risks and Disease Prognosis in Small-Scale Poultry Farming in India

AbstractPoultry farming plays a vital role in supporting rural livelihoods, enhancing nutritional security and contributing to the economic development of India. As one of the fastest-growing agricultural sectors, it provides an accessible and affordable source of animal protein...

Change of the burden of infectious diseases and antimicrobial resistance in India: a systematic analysis for the Global Burden of Disease Study 2019 and 2021

Infectious diseases and antimicrobial resistance (AMR) remain one of the major causes of mortality and disability in India. But age- and pathogen-specific evidence on recent changes in AMR burden is limited. We analysed India-specific data from the Global Burden of Disease Antimi...

Drought and flood risk assessment under the IPCC risk framework in an agriculturally dominated tropical river basin, India

Climate change increases the severity and frequency of water-related hazards in tropical areas, posing significant risks to agriculture as well as the livelihoods of rural communities. The present work advocates an integrated approach to climate-induced risk assessment of agricul...

Does experience of emotional invalidation in childhood lead to growth – a qualitative enquiry using Interpretative phenomenological analysis

Abstract Background Severe abuse is not the only variant of unpleasant experiences in childhood. Childhood maltreatment in the form of emotional invalidation is potent in shaping future behaviors, both adaptive and maladaptive. Traumatic experiences in childhood are such occurren...

Typification of Four Names in the Genus Anaphalis (Asteraceae: Gnaphalieae) With Note on the Distribution of Anaphalis xylorhiza in India

ABSTRACT During an ongoing taxonomic revision of the genus Anaphalis in India, the need for typification of several names came to light. Lectotypes are designated here, in accordance with the ICN (Madrid Code), for the following four names: Anaphalis griffithii , Anaphalis virgat...

Temperature‐Dependent Regiodivergent [3 + 2] Cycloaddition of Azomethine Ylides With (E)‐5‐Benzylidenethioxoimidazolidin‐4‐One

An efficient route is developed to gain access to novel dispiro[imidazolidine‐4,1′‐pyrrolo[2,1‐a] isoquinoline‐3′,3″‐indoline]‐2″,5‐dione skeletons by a one‐pot three‐component [3 + 2] cycloaddition reaction of (E)‐5‐benzylidenethioxoimidazolidin‐4‐ones, isatin derivatives, and 1...

The Sobolev inequalities along the Ricci-Bourguignon flow and applications

‎Consider a closed Riemannian manifold $M$ where the metrics $g(t)$ evolve by the Ricci-Bourguignon flow (RBF)‎.‎The paper first derives a Sobolev inequality along the RBF‎. ‎Then‎, ‎by applying this‎ ‎Sobolev inequality we obtain a linear parabolic estimate and an upper bound es...

CharacterizingBH Bound and Resonant States for PlasmaEdge Applications

Abstract The International Thermonuclear Experimental Reactor (ITER) is presently being designed to be a full tungsten machine with boronized walls. A consequence of boronization is the formation of boron hydrides at the plasma edge. With this in view, we have made detailed calcu...

A Comparative Study of Sports Injury Incidence and Patterns Between Under-19 and Senior Athletes

Abstract Background: While participation in sports aids overall physical and mental development, it inherently creates a risk of sports injuries. Significant variations in injury patterns occur based on age, training intensity, and developmental stage. Understanding age-specific...
