A novel fluorescent "turn-on" chemosensor for nanomolar detection of Fe(III) from aqueous solution and its application in living cells imaging

An electronically active and spectral sensitive fluorescent “turn-on” chemosensor (BTP-1) based on the benzo-thiazolo-pyrimidine unit was designed and synthesized for the highly selective and sensitive detection of Fe³⁺ from aqueous medium. With Fe³⁺, the sensor BTP-1 showed a remarkable fluorescence enhancement at 554 nm (λex=314 nm) due to the inhibition of photo-induced electron transfer. The sensor formed a host-guest complex in 1:1 stoichiometry with the detection limit down to 0.74 nM. Further, the sensor was successfully utilized for the qualitative and quantitative intracellular detection of Fe³⁺ in two liver cell lines i.e., HepG2 cells (human hepatocellular liver carcinoma cell line) and HL-7701 cells (human normal liver cell line) by a confocal imaging technique

Agro-waste valorization for sustainable economy of sugar mills in India

Indian sugar mills produce a large volume of agro-waste sugar cane bagasse (SCB), which, due to its improper use, causes environmental issues. Contrastingly, the valorization of SCB by integrating advanced technologies for biochemical production can alleviate waste disposal problems, enhance resource utilization, and promote a circular economy. The present review explores recent advances in SCB-derived valuable biochemicals such as bioethanol, biogas, xylitol, carboxylic acids, 2,3-butanediol, and furfural using advanced pretreatment techniques and engineered strains. Furthermore, it discusses the challenges and opportunities in bio-chemical production, the economic and environmental assessment, and the implications of the Government of India’s (GOI) valuable schemes for agro-waste valorization

Selective Flotation of Scheelite and Calcite

The gold tailings from Gold Fields containing low scheelite values has a compled mineralogy with hornblende, quartz, arsenopyrite and calcite as major gangue minerals. The most difficult problem in scheelite flotation is not the removal of the siliceous or sulphide gangue, but the separation of Scheelite and calcite minerals which have similar surface properties. This is greatly influenced by many factors(1)such as (1) the extent of adsorption of the collectors (2) the dissolution of the minerals and the interference by the released species and (3) the intera-ction of adsorbed ions with the mineral surface. Direct flotation tests to recover scheelite from tailings failed due to the dilution of the concentrate by calcite. Hence to adopt the flotation process successfully, it is nece-ssary to depress the calcite selectively which is not achi-eved easily(2) due to the presence of small amounts of Ca, Mg and Fe salts and the lean grade of the ores to be treated. Slime coating(3) is also another factor adver-sely affecting the flotation of scheelite. The present study is an attempt to improve the selectivity of separ-ation of scheelite, based on the flotation of pure clacite-scheelite system using sodium oleate as collector

In addition, it revealed that such learning also had its downsides on a student's academic scores. According to the study, online education has both positive and negative effects in an academic setting as well as offering a flexible mode with minimal pressure coupled with social separation. This paper is aimed at examining the impact of using online learning on student’s achievements in schools due to the spread of the pandemic. This objective was achieved through a meta-analysis of relevant studies that examined the impact of online education on students academics achievements in various nations from the years 2020 to 2022. In addition, this study will serve as a reference for future research that investigates whether learning outcomes have improved or deteriorated in a post-pandemic world. Qualitative methodological approach was adopted in this research for investigating the views of university and college students’ concerning the quality of online education against their own online experience.  Different digital and printed documents were gathered. Student positive and negative experiences were analysed. Some of those experiences were also identified as factors contributing towards them. The findings reveal that online education impacts academic achievement in an intermediate manner

General consideration of Pakshaghata and its management using natural medicine and Ayurveda principles

Pakshaghata (Hemiplegia) is one of the most common causes of death especially in elder age group. Pakshaghata mainly occurs due to the obstruction of cerebral blood vessels, ischemia, and lack of glucose metabolism and weakness of nerve cell. Loss of movement, sensory deficit, dysarthria, atrophy, stiffness and disturbed nerve impulses are the major symptoms of disease. Ayurveda offers various treatment modalities for the management of Pakshaghata such as; use of herbs & formulation, yoga and Shodhana Chikitsa. Present article described various approaches of ayurveda for the management of Pakshaghata including natural herbs and Shodhana Chikitsa

FORMULATION AND EVALUATION OF ION-SENSITIVE IN-SITU NASAL GEL OF ZOLMITRIPTAN

In situ gel system is novel drug delivery system in which there is transition of sol to gel on external stimuli like change in pH, temperature or change in ion concentration (sol-gel transition). In the present study various formulations were prepared by using gellan gum as gelling agent and HPMC K100 as controlled or sustained release polymer. All the formulations were evaluated for various parameters like pH, viscosity, drug content, gel strength, mucoadhesive strength and drug release. At minimum concentration of polymer lose their integrity and at maximum concentration stiff gel were formed. At optimized concentration of gelling agent and HPMC K100 showed in situ gelling with all parameter in range. In Vitro release data revealed that the optimized formulation showed controlled and sustained drug release pattern. The optimized formulation also obeyed korsmer Peppas model equation and which showed the release exponent n value 0.765. Thus the ex vivo higher bioavailability can be expected from the optimized formulation.Â

Moduli Stabilization in Brane Gas Cosmology with Superpotentials

In the context of brane gas cosmology in superstring theory, we show why it is impossible to simultaneously stabilize the dilaton and the radion with a general gas of strings (including massless modes) and D-branes. Although this requires invoking a different mechanism to stabilize these moduli fields, we find that the brane gas can still play a crucial role in the early universe in assisting moduli stabilization. We show that a modest energy density of specific types of brane gas can solve the overshoot problem that typically afflicts potentials arising from gaugino condensation.Comment: minor changes to match the journal versio
