Rationally designed nanocarriers for intranasal therapy of allergic rhinitis: influence of carrier type on in vivo nasal deposition
Marwa Ahmed Sallam, Hala Mahmoud Helal, Sana Mohamed Mortada Department of Industrial Pharmacy, Faculty of Pharmacy, Alexandria University, Alexandria, Egypt Abstract: The aim of this study is to develop a locally acting nasal delivery system of triamcinolone acetonide (TA) for the maintenance therapy of allergic rhinitis. The effect of encapsulating TA in different nanocarriers on its mucosal permeation and retention as well as in vivo nasal deposition has been studied. A comparative study was established between polymeric oil core nanocapsules (NCs), lipid nanocarriers such as nanoemulsion (NE), and nanostructured lipid carriers (NLCs). The elaborated nanocarriers were compared with TA suspension and the commercially available suspension “Nasacort®”. The study revealed that NC provided the highest mucosal retention, as 46.14%±0.048% of the TA initial dose was retained after 24 hours, while showing the least permeation through the nasal mucosa. On the other hand, for TA suspension and Nasacort®, the mucosal retention did not exceed 23.5%±0.047% of the initial dose after 24 hours. For NE and NLC, values of mucosal retention were 19.4%±0.041% and 10.97%±0.13%, respectively. NC also showed lower mucosal irritation and superior stability compared with NE. The in vivo nasal deposition study demonstrated that NC maintained drug in its site of action (nasal cavity mucosa) for the longest period of time. The elaborated polymeric oil core NCs are efficient carriers for the administration of nasally acting TA as it produced the least permeation results, thus decreasing systemic absorption of TA. Although NCs have been administered via various routes, this is the first study to implement the polymeric oil core NC as an efficient carrier for localized nasal drug delivery.

Hyastenus hilgendorfi
Hyastenus hilgendorfi(De Man, 1887) The carapace of H. hilgendorfi is distinguished by the presence of clusters of spinules located only on the orbital regions (Figure 4 (a)). Each cluster comprises 27–55 short, tooth-shaped spinules with pointed tips (Figure 4 (b)). Nine setal forms belonging to three main types (hooked, pappose and cuspidate) and a novel one (frilled spatulate setae) were found and photographed. No distinct differences were observed among size ranges for males or for females. A description is given for each setal type /form encountered, including average widths and lengths, presence of substructures and their average lengths as well as areas of the integument where the setal type was mainly encountered. No pores were present on any of the described forms. All setal types showed infracuticular articulation.Published as part of Osman, Marwa M., Sallam, Wafaa S., Madkoura, Fedekar F. & Wicksten, Mary K., 2021, Morphology of camouflage by encrustation in the spider crabs Schizophrys dahlak and Hyastenus hilgendorfi (Decapoda: Brachyura: Majoidea: Epialtidae) from the Suez Canal, Egypt, pp. 2047-2064 in Journal of Natural History 55 (33 - 34) on page 2054, DOI: 10.1080/00222933.2021.1973132, http://zenodo.org/record/572778
Schizophrys dahlak Griffin and Tranter 1986
Schizophrys dahlakGriffin and Tranter, 1986 The carapace of S. dahlak is characterised by two distinguishing features: surface protuberances of different heights and intervals on which clusters of setae are found (Figure 2 (a)), and patches of denticles with a tusk or tooth shape and a blunt tip. There are three patterns of distribution, with the first pattern being the most common (Figure 2 (b–d)). Pattern (1) Single denticles found in rows, L 1.7 μm and W 0.5 μm. Interval 4 μm, widely distributed on all regions of the exoskeleton (Figure 2 (b)). Pattern (2) Paired denticles found in rows, L 2.7 μm and W 1 μm; interval 6.5 μm, found on left and right branchial regions of carapace (Figure 2 (c)). Pattern (3) Twelve spinules of L 0.3 μm, elliptical in shape, facing the base of a single denticle of L 2.03 μm, interval 3 μm. Commonly distributed on frontal region of carapace and on abdomen (Figure 2 (d)). Eight setal types were discovered and photographed on the exoskeleton. No notable difference was seen between males and females or among the size ranges. A description is provided for each setal type observed, including average width and length, presence of outgrowths and their average length, as well as areas of the integument where the setal type was mainly encountered. No pores were present on any of the described forms. All setal forms showed infracuticular articulation (an articulation in the form of a socket, which is drawn into the general cuticle).Published as part of Osman, Marwa M., Sallam, Wafaa S., Madkoura, Fedekar F. & Wicksten, Mary K., 2021, Morphology of camouflage by encrustation in the spider crabs Schizophrys dahlak and Hyastenus hilgendorfi (Decapoda: Brachyura: Majoidea: Epialtidae) from the Suez Canal, Egypt, pp. 2047-2064 in Journal of Natural History 55 (33 - 34) on page 2051, DOI: 10.1080/00222933.2021.1973132, http://zenodo.org/record/572778
How MTSS and UDL Frameworks Can Be Used to Reach All Learners and Reduce Unnecessary Special Education Evaluations
The global COVID pandemic changed the educational landscape as we knew it in a drastic way. With the rise of special education evaluation requests and a need to strengthen the MTSS framework across schools, an urgency developed around the intersection of MTSS with interventions, including how accurately implementing UDL strategies could alleviate the pressure on the MTSS framework at schools. Many schools who were previously reactive to students who were struggling academically or behaviorally needed to take a more proactive and intentional approach. The author of this thesis reviewed a number of relevant literature that explored different examples of educational institutions with schoolwide structures where special education teachers and general education teachers work together and the MTSS process ended up being more inclusive and collaborative. This leads to better data gathering for students and stronger student outcomes. The purpose of this thesis is to explore best practices in supporting the development of a strong MTSS process and reducing the number of unnecessary special education evaluations
Optimization, ex vivo permeation, and stability study of lipid nanocarrier loaded gelatin capsules for treatment of intermittent claudication
Marwa Ahmed Sallam,1 María Teresa Marín Boscá21Department of Industrial Pharmacy, Faculty of Pharmacy, Alexandria University, Alexandria, Egypt; 2Department of Pharmacy and Pharmaceutical Technology, Faculty of Pharmacy, Granada University, Granada, Spain Abstract: In this study, an optimized nanodispersible oral dosage form (containing a lactate ester) was developed for cilostazol (CZL). CZL is a phosphodiesterase inhibitor used for intermittent claudication. We aimed to improve the dissolution rate and absorption of CZL giving it a better chance of oral bioavailability, and to evaluate its stability on storage. Suitable compositions of nanoemulsion preconcentrate formulations were screened via solubility and compatibility tests. Response surface methodology and a desirability approach were applied to optimize preconcentrates containing minimum amount of surfactant mixture, maximum amount of lipid, and possessing the smallest globule size, with the highest emulsification and dissolution rates and minimum risk of drug precipitation. As part of the optimization process, the main effect, interaction effects and quadratic effects of amounts of lipid, and surfactant/co-surfactant ratio on % transmittance, globule size, emulsification time, drug precipitation, and drug release were investigated. The optimized formulation consisting of 28.9% butyl lactate, 28.9% Capryol®, 27.82% Solubilisant Gamma® 2429, and 14.18% Transcutol® possessing a globule size of 60 nm was mixed with Aerosil® 200. This gave uniform free flowing granules, which were characterized for surface and powder properties. The self-nanoemulsifying granules (SNEGs) filled into hard gelatin capsules showed two- and threefold increase in CZL released compared with conventional tablet and pure drug, respectively. The amount of drug permeated using non-everted sac technique from the SNEGs was twofold higher than that permeated from the tablet suspension. The shelf life was 526 days at 25°C. Our study illustrated that the developed SNEGs, with bioenhancing ingredients, held great potential as a superior alternative to traditional oral formulations of CZL.Keywords: butyl lactate, preconcentrates, cilostazol, desirability, Solubilisant Gamm
