Patel, Pratikkumar;Pol, Anuradha;Kalaria, Dhaval;Date, Abhijit A.;Kalia, Yogeshvar;Patravale, Vandana research published 《 Microemulsion-based gel for the transdermal delivery of rasagiline mesylate: In vitro and in vivo assessment for Parkinson’s therapy》, the research content is summarized as follows. Rasagiline mesylate (RSM) is a selective and irreversible monoamine oxidase B inhibitor used for the treatment of Parkinson’s disease (PD). However, its unfavorable biopharmaceutical properties, such as extensive degradation in the gastrointestinal tract and first-pass metabolism are responsible for its low oral bioavailability and suboptimal therapeutic efficacy. Here, we report the feasibility of delivering RSM via the transdermal route using RSM containing microemulsion-based gel (RSM-MEG) to achieve effective management of PD. Our in vitro skin permeation studies of RSM-MEG showed significantly higher (at least ∼1.5-fold) permeation across rat skin compared to the conventional RSM hydrogel. Our skin irritation studies in rabbits showed that RSM-MEG is safe for transdermal application. Finally, using the rat model of rotenone-induced Parkinsonism, we demonstrated that the topical application of RSM-MEG was equally effective in reversing PD symptoms when compared to oral RSM therapy. Thus, our study confirmed the feasibility and potential of transdermal delivery of RSM via simple topical application of RSM-MEG, and this approach could be an alternative therapeutic intervention for the treatment of Parkinson’s disease.

Pelo, Sharon Pauline;Adebo, Oluwafemi Ayodeji;Green, Ezekiel research published 《 Chemotaxonomic profiling of fungal endophytes of Solanum mauritianum (alien weed) using gas chromatography high resolution time-of-flight mass spectrometry (GC-HRTOF-MS)》, the research content is summarized as follows. Since ancient times medicinal plants have been used as medicine in many parts of the world to promote human health and longevity. In recent years many novel secondary metabolites of plants have been isolated and reported to provide lead compounds for new drug discoveries. Solanum mauritianum Scopoli is native to South America. It is reported to be used by native South Americans during famine as a vegetable and as medicine to cure various diseases. In South Africa the plant is viewed as weed and is facing eradication, however, this plant is a valuable subject for research into its potential pharmaceutical and chem. uses. This study elucidated the metabolic profile of fungal endophytes that have promising bioactive secondary metabolites against pathogenic microorganisms, including mycobacterium species. Fungal endophytes from a weed Solanum mauritianum Scop. were used to synthesize secondary metabolites. Gas chromatograph high-resolution time-of-flight mass spectrometry (GC-HRTOF-MS) was used to analyze volatile compounds to prove that potentially fungal endophytes could be extracted from this weed. Extracts obtained with Et acetate were screened for phytochems. and analyzed using a gas chromatograph high-resolution time-of-flight mass spectrometry system. Principal component anal. was used to compare the gas chromatograph high-resolution time-of-flight mass spectrometry data for differences/similarities in their clustering. Phytochem. screening was conducted on the crude extracts of fungal endophytes obtained from different parts of Solanum mauritianum Scopoli (leaves, ripe fruit, unripe fruit and stems). Phytochem. screening indicated the presents of alkaloids, flavonoids, glycosides, phenols, quinones and saponins. Quinones were not present in the crude extracts of Fusarium sp. A total of 991 compounds were observed in the fungal endophytes, and Cladosporium sp. (23.8%) had the highest number of compounds, compared to Paracamarosporium leucadendri (1.7%) and Talaromyces sp. (1.5%). Some volatile compounds such as eicosane, 2-pentadecanone, 2-methyloctacosane, hexacosane and tridecanoic acid Me ester with antibacterial activity were also observed Compositional variations between the plant and fungal endophyte phytochems. were observed The results of this study indicate that fungal endophytes from Solanum mauritianum Scop. contain compounds that can be exploited for numerous pharmaceutical and medicinal applications.

Montano, Alfredo;Cortes-Delgado, Amparo;Sanchez, Antonio Higinio;Ruiz-Barba, Jose Luis research published 《 Production of volatile compounds by wild-type yeasts in a natural olive-derived culture medium》, the research content is summarized as follows. The production of volatile compounds in naturally fermented green table olives from Manzanilla cultivar was investigated. A total of 62 volatile compounds were detected after 24 wk of fermentation To clarify the contribution of yeasts to the formation of these compounds, such microorganisms were isolated from the corresponding fermenting brines. Five major yeast strains were identified: Nakazawaea molendinolei NC168.1, Zygotorulaspora mrakii NC168.2, Pichia manshurica NC168.3, Candida adriatica NC168.4, and Candida boidinii NC168.5. When these yeasts were grown as pure cultures in an olive-derived culture medium, for 7 days at 25°C, the number of volatiles produced ranged from 22 (P. manshurica NC168.3) to 60 (C. adriatica NC168.4). Contribution of each yeast strain to the qual. volatile profile of fermenting brines ranged from 19% (P. manshurica NC168.3) to 48% (Z. mrakii NC168.2 and C. adriatica NC168.4). It was concluded that C. adriatica NC168.4 presented the best aromatic profile, being a solid candidate to be part of a novel starter culture to enhance the organoleptic properties of naturally fermented green table olives.

The authors attempted to fabricate a novel lipid-based formulation of a lipophilic drug, nisoldipine (NISO). As NISO belongs to BCS class 2 drug, it suffers from low bioavailability (5%). Hence, the research was intended to ameliorate oral bioavailability of NISO via intestinal lymphatic transport. The NISO loaded self microemulsifying drug delivery system (SMEDDS) (NISO SMEDDS) was prepared using Peceol, Cremophor EL, and Transcutol HP. The Cremophor EL and Transcutol HP at 1:1 ratio showed maximum microemulsifying area, and average globule size was 16.78 ± 0.97 nm with PDI 0.121 ± 0.024. Cellular uptake studies (confocal microscopy and flow cytometry) using Caco-2 cells depicted higher fluorescence with coumarin-6 loaded SMEDDS as that of coumarin-6 solution which indicated deeper penetration. Mean fluorescence intensity (MFI) of coumarin-6 loaded SMEDDS was significantly improved (9.92-fold) in contrast to coumarin-6 solution The NISO SMEDDS showed enhanced permeability (5.02 times) across Caco-2 cells compared to NISO suspension. The bioavailability improvement with NISO SMEEDS was 2.14 times relative to suspension, and lymphatic uptake was involved in oral absorption of NISO SMEDDS.

Muniz, Adriana;Du, Xiaofen research published 《 Egg White Partially Substituted with Mushroom: Volatile Aroma Impartment from Mushroom and Impact of Mushroom Type, Proportion, and Cooking Method》, the research content is summarized as follows. This study investigated volatiles in 16 developed blends, in which egg whites were partially replaced with white and crimini mushrooms (0%, 10%, 20%, and 30%) and then roasted and steamed, resp. A solid-phase microextraction-gas chromatog.-mass spectrometry anal. identified ~50 volatiles in raw egg whites, while the number of volatiles increased to over 70 in steamed and roasted egg whites. Compared to raw egg white, the total volatile abundance did not significantly change, but alcs., ketones, heterocyclic compounds, and sulfurs significantly increased (p ≤ 0.05) in cooked egg whites. When egg whites were substituted with 30% mushrooms, the total volatile abundance increased 8-11 times, compared to egg white alone. The dominant volatiles in the egg white-mushroom blends were aldehydes and alcs. followed by ketones, heterocyclic compounds, and sulfurs. Increases in the mushroom proportions led to a significantly higher peak abundance of all volatiles in the blends except sulfurs. Crimini imparted higher amounts of heterocyclic compounds, and white mushrooms had higher sulfurs. Compared to the steam method, roasting significantly increased pyrazines in the blends. This study demonstrated the contribution of mushroom volatiles to egg whites, three impact factors, and the potential utilization of mushroom in food product development.

Mustapha, Abdullateef Taiye;Zhou, Cunshan research published 《 Novel assisted/unassisted ultrasound treatment: Effect on respiration rate, ethylene production, enzymes activity, volatile composition, and odor of cherry tomato》, the research content is summarized as follows. Previous studies on the application of a novel multifrequency ultrasound washing treatment have proven to be effective in guaranteeing microbial safety, and enhancing the quality of cherry tomato. Nevertheless, there is still a need to evaluate the effect of these treatments on the metabolic activity, volatile profile, and sensorial quality of the fruit. This study evaluated the above parameters of cherry tomato treated with optimized assisted and un-assisted multifrequency ultrasound. The treatments slightly enhanced the enzyme activities and inhibit ethylene production and respiration rate. The results indicated that the treatment with 20/40 kHz and aqueous ozone (0.85 ± 0.2 mg/L) for 10 min enhanced and maintained the volatile compounds (VC). Out of the 44 identified VC, one had odor activity value > 1 and thereby considered as active aroma compound contributing significantly to the aroma of the sample. E-nose anal. indicated that alc., terpenes, and some aromatic compounds are the core indicators of the significant sensors. PCA showed that the processing methods had an influence on the flavor indexes of the tomatoes. The result verified that all the washing techniques did not result in a substantial neg. effect on the tomato, and the treatment with ultrasound and ozone proved to be the best.

Nguyen, David;Secretan, Philippe-Henri;Cotteret, Camille;Jacques-Gustave, Emmanuelle;Greco, Celine;Bodemer, Christine;Schlatter, Joel;Cisternino, Salvatore research published 《 Stability and Formulation of Erlotinib in Skin Creams》, the research content is summarized as follows. Recent studies have highlighted the benefit of repurposing oral erlotinib (ERL) treatment in some rare skin diseases such as Olmsted syndrome. The use of a topical ERL skin treatment instead of the currently available ERL tablets may be appealing to treat skin disorders while reducing adverse systemic effects and exposure. A method to prepare 0.2% ERL cream, without resorting to a pure active pharmaceutical ingredient, was developed and the formulation was optimized to improve ERL stability over time. Erlotinib extraction from tablets was incomplete with Transcutol, whereas DMSO (DMSO) allowed 100% erlotinib recovery. During preliminary studies, ERL was shown to be sensitive to oxidation and acidic pH in solution and when added to selected creams (i.e., Excipial, Nourivan Antiox, Pentravan, and Versatile). The results also showed that use of DMSO (5% v/w), neutral pH, as well as a topical agent containing antioxidant substances (Nourivan Antiox) were key factors to maintain the initial erlotinib concentration The proposed ERL cream formulation at neutral pH contains a homogeneous amount of ERL and is stable for at least 42 days at room temperature in Nourivan cream with antioxidant properties.

Ninya, Nicole;Vallecillos, Laura;Marce, Rosa Maria;Borrull, Francesc research published 《 Evaluation of air quality in indoor and outdoor environments: Impact of anti-COVID-19 measures》, the research content is summarized as follows. This study monitors the presence of 88 volatile organic compounds (VOCs) and semi-volatile organic compounds (semi-VOCs) at the gas phase of seven indoor settings in a school in the city of Tarragona, Spain, and five outdoor locations around the city. The VOCs and semi-VOCs monitored were solvents (∑Solvents), aldehydes (∑Aldehydes), emerging organic compounds (∑EOCs), and other VOCs and semi-VOCs (∑Others). Passive sampling campaigns were performed using Carbopack X tubes followed by thermal desorption coupled to gas chromatog. with mass spectrometry (TD-GC-MS). Overall, 70 of the target compounds included in the method were determined in the indoor air samples analyzed, and 42 VOCs and semi-VOCs in the outdoor air samples. Our results showed that solvents were ubiquitous throughout the school at concentrations ranging from 272μg m^-3 to 423μg m^-3 and representing 68%-83% of total target compounds (∑Total). The values of ∑Total in 2021 were three times as high as those observed at the same indoor settings in 2019, with solvents experiencing the greatest increase. A plausible explanation for these observations is the implementation of anti-COVID-19 measures in the indoor settings, such as the intensification of cleaning activities and the use of hydroalcoholic gels as personal hygiene. The ∑Total values observed in the indoor settings evaluated were twenty times higher than those found outdoors. ∑Solvents were the most representative compounds found indoors (74% of the ∑Total). The concentrations of VOCs and semi-VOCs observed in the outdoors were strictly related to combustion processes from automobile traffic and industrial activities, with ∑Others contributing 58%, ∑Solvents 31%, and ∑Aldehydes 11% of the ∑Total. EOCs, on the other hand, were not detected in any outdoor sample.

Nanostructured lipid carrier (NLC) formulations were prepared using optimized ART concentration of 0.25 g dissolved in 5% w/v mixture of solid (Gelucire 43/01 and Phospholipon 85G) and liquid (Transcutol) lipids at 90°C. An aqueous surfactant phase at 90°C was added (dropwise) under magnetic stirring (1000 rpm) for 5 min. The pre-emulsion was speedily homogenized at 28,000 rpm for 15 min and further probe sonicated at 60% amplitude (15 min). Resultant sample was cooled at room temperature and frozen at -80°C prior to lyophilization. The freeze-dried sample was used for solid-state characterization as well as in the formulation of transdermal nanogels using three polymers (Carbopol 971P, Poloxamer 407, and Prosopis africana peel powder) to embed the ART-NLC, using ethanol as a penetration enhancer. Transdermal ART-nanogels were characterized accordingly (phys. examination, pH, drug content, rheol., spreadability, stability, particle size and morphol., skin irritation, in vitro and ex vivo skin permeation, and anal. of permeation data), P < 0.05. Overall, ART nanogels prepared from Poloxamer 407 showed the most desirable drug permeation, pH, swellability, spreadability, viscosity, and transdermal antiplasmodial properties superior to PAPP-ANG > C971P-ANG. A two-patch/wk concurrent application of the studied nanogels could ofer 100% cure of malaria as a lower-dose (50 mg ART) patient-friendly regimen devoid of the drug’s many side efects.

Noori, Abdolvahed;Kim, Hyeok;Kim, Myung Hee;Kim, Keumyong;Lee, Kibaek;Oh, Hyun-Suk research published 《 Quorum quenching bacteria isolated from industrial wastewater sludge to control membrane biofouling》, the research content is summarized as follows. N-acylhomoserine lactone (AHL)-based bacterial communication through quorum sensing (QS) is one of the main causes of biofouling. Although quorum quenching (QQ) has proven to be an effective strategy against biofouling in membrane bioreactors (MBRs) for municipal wastewater treatment, its applicability for industrial wastewater treatment has rarely been studied. This is the first study to isolate QQ strains from the activated sludge used to treat industrial wastewater containing toxic tetramethylammonium hydroxide (TMAH) and 1-methyl-2-pyrrolidinone. The two QQ strains from genus Bacillus (SDC-U1 and SDC-A8) survived and effectively degraded QS signals in the presence of TMAH. They also showed resistance to toxic byproducts of TMAH degradation such as ammonium and formaldehyde. They effectively reduced the biofilm formation of Pseudomonas aeruginosa PAO1 and mixed community of activated sludge. The strains isolated in this study thus have the potential to be employed to reduce membrane biofouling in MBRs during the treatment of TMAH-containing wastewater.
