Abstract
This study introduces a novel approach of repetitive modeling to simulate the pathological process of recurrent gout attacks in humans. This methodology addresses the instability issues present in rat models of gout, providing a more accurate representation of the damage recurrent gout episodes inflict on human skeletal systems. A soluble nanoneedle system encapsulating colchicine and iguratimod ethosomal formulations was developed. This system aims to modulate inflammatory cytokines and inhibit osteoclast activity, thereby treating inflammatory pain and bone damage associated with recurrent gout. Additionally, a comprehensive evaluation of the microneedles' appearance, morphology, mechanical properties, and penetration capability confirmed their effectiveness in penetrating the stratum corneum. Dissolution tests and skin irritation assessments demonstrated that these microneedles dissolve rapidly without irritating the skin. In vitro permeation studies indicated that transdermal drug delivery via these microneedles is more efficient and incurs lower drug loss compared to traditional topical applications. In vivo pharmacodynamic assessments conducted in animal models revealed significant analgesic and anti-inflammatory effects when both types of microneedles were used together. Further analyses, including X-ray imaging, hematoxylin and eosin (H&E) staining, Safranin-O/fast green staining, tartrate-resistant acid phosphatase staining, and quantification of osteoclasts, confirmed the bone-protective effects of the microneedle combination. In conclusion, the findings of this research underscore the potential of this novel therapeutic approach for clinical application in the treatment of recurrent gout.

Abstract
The fundamental purpose of this study was to develop a stable lyophilised finasteride nanosystem (FNS-NS) for topical delivery. The FNS-NS was fabricated using an ultrasonication technique. The impact of two different cryoprotectants on the physicochemical characteristics of FNS-NS before and after lyophilisation was thoroughly investigated. The lyophilised FNS-NS had spherical shape with particle size lied between 188.6 nm ± 4.4 and 298.7 nm ± 4.7, low PDI values (0.26 ± 0.02 to 0.32 ± 0.02) and zeta potential ranging from -38.3 to +53.3 mV. The confocal laser microscopy depicted a comparatively higher cellular internalisation achieved for undecorated FNS-NS with respect to its chitosan-decorated counterpart. The lyophilised FNS-NS was stable for 90 days at proper storage conditions. The FNS-NS with 15% trehalose had appropriate physicochemical attributes that could be a promising carrier for topical delivery to treat androgenic alopecia.

Abstract
INTRODUCTION The current work aimed to formulate a novel chitosan-based finasteride nanosystem (FNS-NS) for skin delivery to optimize the drug availability in skin for a longer time and enhance ex vivo performance of finasteride against androgenic alopecia. METHODS Both undecorated and chitosan decorated FNS-NSs were synthesized by a high energy emulsification technique. All the prepared nanosystems were further subjected to physicochemical characterizations like pH, viscosity, encapsulation efficiency, surface morphology and in vitro drug release behavior. The influence of the nanosystem on the drug permeation and retention in rat skin was examined using Franz diffusion cell apparatus. RESULTS The droplet size of developed nanosystems ranged from 41 to 864 nm with a low polydispersity index. The zeta potential of the nanosystems was between -10 mV and +56 mV. This chitosan decorated nanosystem exhibited controlled drug release, ie about 78-97% in 24 h. Among all the nanosystems, our chitosan decorated formulation (F5) had low drug permeation (16.35 µg/cm2) and higher drug retention (10.81 µg/cm2). CONCLUSION The abovementioned results demonstrate satisfactory in vitro drug release, skin retention profiles and ex vivo performance with chitosan decorated FNS-NS (F5). This optimized formulation could increase drug availability in skin and could become a promising carrier for topical delivery to treat androgenic alopecia.

Abstract
Acne vulgaris is the most prevalent disorder in the period before puberty when increased adrenal androgen level causes enlargement of the sebaceous glands and it increased the production of sebum on the face, chest, and back. This disease is caused due to interaction between many causative agents or pathogenic components which lead to formation of the acne and those are seborrhea, follicular hyper keratinization, microbial formation of pilosebaceous unit by Propionibacterium acne and arrival of inflammatory mediators. Tazarotene is a well-known retinoid related to vitamin A that belongs to an acetylenic class of retinoid, used in the management of acne. Oral administration of Tazarotene causes changes in bone morphology after prolonged exposure to high doses, which also exhibit teratogenicity but this does not occur with topical delivery. Ethosomes are non-invasive delivery carriers enabling drugs to reach to the bottom of the skin layers and/or the system and transfersomes are the self-adaptable ultra-deformable flexible elastic bilayer vesicles composed of phospholipids able to penetrate through the pores of skin even smaller than its size. Present research aims the comparative evaluation of ethosomal and transfersomal gels loaded with Tazarotene in the treatment of acne. In the present study, ethosomes and transfersomes were formulated by the cold method and hand-shaking method, respectively, followed by loading of Tazarotene and development into gel formulation. The formulated gel samples were evaluated for in vitro release study, in vitro permeation study, in vitro anti-acne study, in vivo percutaneous permeation study by CLSM, and in vivo anti-acne study. The results proved that both the formulated ethosomal and transfersomal gels have better permeation through the skin but ethosomal gel showed better release in comparison to transfersomal gel, also final gels exhibited the anti-acne potentiality.

Abstract
Hair loss affects a large number of people worldwide and it has a negative impact on the quality of life. Despite the availability of different drugs for the treatment of hair disorders, therapeutic options are still limited and scarcely effective. An innovative strategy to improve the efficacy of alopecia treatment is presented in this work. Finasteride, the only oral synthetic drug approved by Unites States Federal Drug Administration, was loaded in phospholipid vesicles. In addition, baicalin was co-loaded as an adjuvant. Their effect on hair growth was evaluated in vitro and in vivo. Liposomes, hyalurosomes, glycerosomes and glycerol-hyalurosomes were manufactured by using a simple method that avoids the use of organic solvents. All the vesicles were small in size (∼100 nm), homogeneously dispersed (polydispersity index ≤0.27) and negatively charged (∼-16 mV). The formulations were able to stimulate the proliferation of human dermal papilla cells, which are widely used in hair physiology studies. The analysis of hair growth and hair follicles of C57BL/6 mice, treated with the formulations for 21 days, underlined the ability of the vesicles to improve hair growth by the simultaneous follicular delivery of finasteride and baicalin. Therefore, the developed nanosystems can represent a promising tool to ensure the efficacy of the local treatment of hair loss.

Abstract
In the present study, iron oxide nanoparticles, in the form of maghemite core coated with lauric acid (ION), were synthesized and loaded with finasteride (FIN) or dutasteride (DUT) as a novel drug delivery system for the topical treatment of alopecia. Additionally, developed formulations (FIN-ION and DUT-ION) were completely elaborated with components involved in the follicle metabolism, i.e., lauric acid, which acts as a 5α-reductase inhibitor, and iron which deficiency has been related to hair loss aggravation. Stability assessment conducted over the course of 90 days showed they are highly stable, with pH 7.4, constant EE% (>99%), and practically unchanged particle size and zeta potential. Besides drug distribution, the actual number of iron oxide nanoparticles, through a newly developed method using ferromagnetic resonance, was determined in each skin layer following permeation experiments. Despite the same donor concentration of colloids, nanoparticle distribution in the skin varied according to the loaded molecule. While DUT did not interfere with the nanoparticle natural tendency to accumulate within the hair follicle shafts, FIN presence hampered nanosystem interaction with the skin. Still, both formulations provided a higher skin drug penetration, compared to each respective control solution. Additionally, iron nanocarriers present a desirable visual characteristic, as the dark color aspect might instantly help disguise scarce hair follicle areas. These findings suggest the nanoformulations are highly promising for alopecia therapies.

Abstract
Thymoquinone (TQ) is a quinone-based phytochemical that was first identified in 1963 in Nigella sativa (black cumin seed) by El-Dakhakhany. Based on the ideal characteristics of transdermal delivery, TQ is potentially an attractive candidate for transdermal drug delivery. The aim of this study was to investigate the feasibility of transdermal delivery of TQ and to assess the effect of an ethanol and propylene glycol donor solvent system along with various compositions of receptor solvents. The effects of penetration enhancers on the in vitro skin permeation and TQ skin absorption were studied using human cadaver skin in Franz diffusion cells. The permeation of saturated solutions of TQ was investigated with 5% v/v of each of the following enhancers: Azone (laurocapram), Transcutol® P (Tc), oleic acid, ethanol, Polysorbate 80 (Tween 80), and N-methyl-pyrrolidone (NMP). The results indicated that Azone, oleic acid, and Tc were able to provide adequate TQ flux and may be the agents of choice for use in a novel transdermal formulation of TQ. These penetration enhancers were also able to generate TQ reservoirs in the skin that may be useful to provide sustained release of TQ from the stratum corneum over longer periods of time.

Abstract
Topical and transdermal drug delivery has great potential in non-invasive and non-oral administration of poorly bioavailable therapeutic agents. However, due to the barrier function of the stratum corneum, the drugs that can be clinically feasible candidates for topical and transdermal delivery have been limited to small-sized lipophilic molecules. Previously, we fabricated a novel iontophoretic system using reverse electrodialysis (RED) technology (RED system). However, no study has demonstrated its utility in topical and/or transdermal delivery of poorly permeable therapeutic agents. In this study, we report the topical delivery of fluorescein isothiocyanate (FITC)-hyaluronic acid (FITC-HA) and vitamin C and the transdermal delivery of lopinavir using our newly developed RED system in the in vitro hairless mouse skin and in vivo Sprague-Dawley rat models. The RED system significantly enhanced the efficiency of topical HA and vitamin C and transdermal lopinavir delivery. Moreover, the efficiency and safety of transdermal delivery using the RED system were comparable with those of a commercial ketoprofen patch formulation. Thus, the RED system can be a potential topical and transdermal delivery system for various poorly bioavailable pharmaceuticals including HA, vitamin C, and lopinavir.

Abstract
A new minoxidil analogue was detected in an illegal dietary supplement advertised as a hair-growth treatment. The analogue was identified using ultra-performance liquid chromatography (UPLC), high-resolution mass spectrometry (LC-HR-MS) and nuclear magnetic resonance (NMR) spectroscopy. The compound was structurally elucidated as a minoxidil analogue in which the piperidinyl group of minoxidil was replaced with a pyrrolidinyl group corresponding to a molecular formula of C8H13N5O. The new analogue has been named triaminodil. As this is the first report of the compound, there are no chemical, toxicology or pharmacological data available.
