We have calculated the in-medium magnetic moments of octet baryons in the presence of hot and dense symmetric nuclear matter. Effective magnetic moments of baryons have been derived from medium modified quark masses within the chiral SU（3） quark mean field model. Further, for better insight into the medium modification of baryonic magnetic moments, we have considered the explicit contributions from the valence quarks, sea quarks and the sea orbital angular momentum of sea quarks. These effects have been successful in giving the description of baryonic magnetic moments in vacuum. The magnetic moments of baryons are found to vary significantly as a function of density of nuclear medium.

Traumatic brain injury （TBI） results in a range of neuroinflam- matory events that vary depending on the type and extent of in- jury. Central to this is the activation of tissue resident microglia and infiltration of peripheral macrophages, which phagocytose debris and/or secrete a range of cytokines, chemokines and oth- er factors which modify the injured environment to promote or inhibit repair （Schwartz et al., 2013）. The reactive macro- phages/microglia are broadly divided into two categories.

Lemon oil (LO), also known as Citrus limonum is a highly volatile essential oil (EO) with potential therapeutic properties like anti-oxidative, anti-proliferative, anti-fungal and anti-cancerous. However, the efficacy of LO is limited due to its physiological factors such as high volatility, poor stability (particularly sensitive to sunlight) and quick degradability upon exposure. To overcome these challenges, we formulated lemon oil loaded nanoemulsion system (LO-NE) (oil-in-water), using aqueous titration method. The formulation comprised of lemon oil (LO), Tween 80 and ethanol as oil, surfactant and co-surfactant phases respectively. The existence zone of NE was established by constructing pseudo-ternary phase diagrams using different concentrations of LO, surfactant and co-surfactant (Smix). The quantitative estimation of LO was performed using a high throughput gas chromatography, revealing the presence of various compounds like Limonene, Alpha-Pinene and Linalyl acetate followed by the estimation of total phenolics and flavonoid content. The characterization of LO-NE indicated the particle size of 60 ± 2.5 nm along with the polydispersity index of 0.125 and zeta potential of −14.9 mV. The size range of the NE particles dispersed in the colloidal system was further verified by TEM micrograph which shows size range between 46.2 - 104.7 nm. All the anti-oxidant assays outcomes exhibited the higher activity of LO-NE in comparison to LO alone with lower IC50 values. The release kinetics statistical data showed that LO-NE had a sustained release and followed the Higuchi’s model in comparison to burst release of LO alone. Lastly, the stability analysis of the optimised formulation (LO-NE) and LO was estimated through antioxidant assay and subjecting them for thermodynamic stability after 6 months. The results attained, showed higher stability and anti-oxidant capability of LO-NE than LO alo

We report the existence of chirped bright and dark solitons for higher order nonlinear Schrodinger equation in the presence of localized dissipation. The parameter domains are delineated in which these solitons exist. It is found that the chirp associated with each of the soliton pulses is directly proportional to intensity and gets saturated at some finite value as the retarded time approaches its asymptotic value. We further show that the higher order nonlinearities in the system such as self-steepening and self-frequency shift do not influence the amplitude of the soliton pulses significantly but primarily control the strength of the localized dissipation.

Human dermal layers are directly bared to the external environmental adversities like pollution, radiation, dust along with various chemical and mechanical stress conditions which constantly lead to the oxidative stress, eventually forming free radicals. These conditions also support the dermal microbial infections by invading the cutaneous layers. Therefore, the most efficient approach accepted globally to combat these complications is to opt for transdermal application of exogenous antioxidants which helps in reducing the ill effects of oxidative stress and promotes the DNA repair. However, many scientific findings exhibited the potential role of Theobroma cacao for providing efficient skin protection. Theobroma cacao known for its vital procyanidin flavonoids, phenolic compounds, methylxanthines, catechin and epicatechin phytoconstituents with numerous health benefits, besides helping in smoothening and softening the damaged skin. These therapeutic benefits of cocoa phytocompounds are attributed to its anti-inflammatory and antioxidative characteristics. This study addresses the fabrication and optimizations of Theobroma cacao extract loaded carbopol hydrogel system for increased antioxidative and antimicrobial effects. It was found in the studies that the hydrogel-based T. cacao extract (TCHG) has significantly improved the therapeutic index of the extract, making it more suitable for transdermal application. The optimized hydrogel was further characterized by physicochemical parameters, SEM analysis and in-vitro release kinetics. The reported findings showed the sustained compound release with comparatively significant antimicrobial activity of TCHG against microbial (Pseudomonas fluorescens, Bacillus licheniformis, Micrococcus luteus, Aspergillus niger, Trichoderma harzianum, Rhizopus oryzae) infections. Also, the higher ROS quenching ability of TCHG as compared to T. cacao extract promises to be an effective transdermal formulation.

Background: Recent decades witnessed a significant growth in terms of phytocompounds based therapeutics, extensively explored for almost all types of existing disorders. They have also been widely investigated in Neurodegenerative disorders (NDDs) and Chlorogenic acid (CGA), a polyphenolic compound having potential anti-inflammatory and anti-oxidative properties, emerged as a promising compound in ameliorating NDDs. Owing to its poor stability, bioavailability and release kinetics, CGA needed a suitable nanocarrier based pharmaceutical design for targeting NDDs. Objective: The current study is aimed at the in-silico validation of CGA as an effective therapeutic agent targeting various NDDs followed by the fabrication of polymeric nanoparticles-based carrier system to overcome its pharmacological limitations and improve its stability. Methods: A successful in-silico validation using molecular docking techniques along with synthesis of CGA loaded polymeric nanoparticles (CGA-NPs) by ionic gelation method was performed. The statistical optimisation of the developed CGA-NPs was done by Box Behnken method and then the optimized formulation of CGA-NPs was characterised using particle size analysis (PSA), Transmission electron microscopy (TEM), Fourier Transform Infrared spectroscopy (FTIR) along with in-vitro release kinetics analysis. Results & Conclusion: The results attained exhibited average particle size of 101.9 ± 1.5 nm, Polydispersibility (PDI) score of 0.065 and a ZP of −17.4 mV. On a similar note, TEM results showed a size range of CGA-NPs between 90 - 110 nm with a spherical shape of NPs. Also, the data from in-vitro release kinetics showed a sustained release of CGA from the NPs following the first-order kinetics suggesting the appropriate designing of nanoformulation.
