Abstract:

In the present work a multifunctional nanoadsorbent was synthesized via a well-designed stepwise route, led to the grafting of an amine group on the interior and acidic sites on the exterior of bimodal mesoporous silica nanoparticles (UVM-7). First, amine and thiol groups were grafted on the interior and exterior pores of silica through co-condensation and post synthesis treatment, respectively. Then, the oxidation of thiol on UVM-7 caused to create sulfonic acid and the subsequent template extraction was carried out to obtain the NH2/UVM-7/SO3H.

Abstract:

The research investigates the pore architecture of UVM-7-like silicas, revealing a hierarchical connectivity of inter- and intra-nanoparticle pores that enhances mass-transfer kinetics. This structure facilitates efficient processes such as gold nanodomain mobility and enzyme adsorption, demonstrating the advantages of nanoparticulated bimodal mesoporous silicas in various applications. Nanoparticulated bimodal mesoporous silicas (NBS) have proved to constitute adequate supports in a variety of applications requiring enhanced accessibility to the active sites.

Abstract:

Abstract This work shows the ability of a hierarchical porous silica-based network with pore systems at two different length scales for enzyme immobilization. Two different enzymes have been selected, lysozyme, a relatively small globular enzyme, and α-L-arabinofuranosidase, a large enzyme of interest in the winemaking industry. The lysozyme immobilization on several silica supports (bimodal porous silicas denoted UVM-7 materials and conventional silica xerogels) has been studied and the loading amounts can be correlated to the open nature and accessibility of the int

In this work, sorbets based on UVM-7 mesoporous silica doped with Fe were synthesized and applied to solid-phase extraction of perfluoroalkyl substances from environmental water samples.

Abstract:

Nine patients with photosensitivity dermatitis and actinic reticuloid syndrome are reported. The rash affected light-exposed skin only in 7 patients and extended to covered sites in 2. Seven were sensitive to UVB, UVA and visible light, one to UVA and one to visible light only. Two patients had significant clinical improvement in spite of both having suffered severe disease previously. Another patient remains exquisitely light-sensitive after 20 years and has developed two squamous cell carcinomas, one of which metastasized to local lymph nodes, and two keratoacanthomas on light-exposed skin.

Abstract:

The liver is a key metabolic organ that is particularly sensitive to environmental factors, including UV radiation. As UV radiation induces oxidative stress and inflammation, natural compounds are under investigation as one method to counteract these consequences. The aim of this study was to assess the effect of topical application of phytocannabinoid-cannabidiol (CBD) on the skin of nude rats chronically irradiated with UVA/UVB, paying particular attention to its impact on the liver antioxidants and phospholipid metabolism. The results of this study indicate that CBD reaches the rat liver wh

Abstract UV light can be used to irradiate platelets to reduce immune responses and activate chemically-mediated pathogen reduction agents. Platelets subjected to UV-based processing methods develop demonstrable losses of in vivo performance. We compared the “lesions” induced by the different wavelengths of UV light on human platelet performance in a SCID mouse animal model of recovery and survival. Previously we demonstrated that severe combined immunodeficient (SCID) mice could be used as an animal model to identify both severely damaged (Blood 106(11), p537a, 2005) and moderately damaged hu

Excessive UV exposure contributes to several pathological conditions like skin burns, erythema, premature skin aging, photodermatoses, immunosuppression, and skin carcinogenesis. Effective protection from UV radiation may be achieved with the use of sunscreens containing UV filters. Currently used UV filters are characterized by some limitations including systemic absorption, endocrine disruption, skin allergy induction, and cytotoxicity. In the research centers all over the world new molecules are developed to improve the safety, photostability, solubility, and absorption profile of new deriv

Ultraviolet radiation from sunlight is essential for human health in many ways such as facilitating vitamin D synthesis while excessive exposure can cause adverse effects such as premature aging, sunburn, and skin cancers. In the USA, between 2007 and 2011, nearly five million adults were treated for skin cancer annually with average treatment costs of $8.1 billion each year. Hence, monitoring daily exposure to sunlight is essential to avoid developing health risks.
