Asian Pacific Journal of Tropical Medicine 2018年第11期11卷 597-608页

Brucellosis is an old, infectious and common zoonosis whose causative agents are Gramnegative bacteria from the Brucella genus. Brucellosis is transmitted through direct contactwith infected animals or using unpasteurized dairy products of goats, pigs, camels, sheep,buffalo and cows. Brucellosis is still the most common zoonosis in the world, with mostof cases occurring in developing countries. Today, an approach to traditional medicine andmedicinal plants, especially with regards to the repeated recommendations of the World HealthOrganization, is a necessity. One-third of chemical drugs are produced by using plants andthere is a high potential to produce more drugs from plants. Medicinal plants are helpful inthe management of various conditions, especially bacterial diseases. Although there is notenough scientific evidence regarding the clinical effectiveness of herbal drugs for the treatmentof brucellosis, there is strong evidence on the antimicrobial effects of herbal drugs to preventinfection. Therefore, this article seeks to describe the antibacterial effects of some plantderived essential oils or extracts, so that they can serve as promising choices to develop newanti-Brucella medications, as suitable alternatives to conventional antibiotics for brucellosis, asmuch as possible, taking into account the benefits of these herbal drugs.

Alginate scaffold has been considered as an appropriate biomaterial for promoting the differentiation of embryonic stem cells toward neuronal cell lineage. We hypothesized that alginate scaffold is suitable for culturing Wharton’s jelly mesenchymal stem cells（WJMSCs） and can promote the differentiation of WJMSCs into neuron-like cells. In this study, we cultured WJMSCs in a three-dimensional scaffold fabricated by 0.25% alginate and 50 m M Ca Cl2 in the presence of neurogenic medium containing 10 μM retinoic acid and 20 ng/m L basic fibroblast growth factor. These cells were also cultured in conventional two-dimensional culture condition in the presence of neurogenic medium as controls. After 10 days, immunofluorescence staining was performed for detecting β-tubulin（marker for WJMSCs-differentiated neuron） and CD271（motor neuron marker）. β-Tubulin and CD271 expression levels were significantly greater in the WJMSCs cultured in the three-dimensional alginate scaffold than in the conventional two-dimensional culture condition. These findings suggest that three-dimensional alginate scaffold cell culture system can induce neuronal differentiation of WJMSCs effectively.

94mTc was produced via natMo(p, xn)94mTc reaction. Deposition of MoO3 on Cu substrate was carried out via two special sedimentation methods for the production of 94mTc. The 533 mg of MoO3, 600 μL of collodium (nitrocellulose) and 3 mL of acetone were used to prepare a MoO3 layer of 11.69 cm2 and 45.81 mg·cm-2. Also, a MoO3 layer was prepared by 533 mg of MoO3, 71.188 mg of methylcellulose and 4 mL of water. The targets were checked by SEM and thermal shock test.

Use of complementary and alternative medicine in pregnant women:A cross-sectional survey in the south of Iran

引用

Journal of Integrative Medicine 2019年第6期17卷 392-395页

作者： Naghmeh Yazdi Alireza Salehi Mina Vojoud Mohammad Hossein Sharifi Ayda Hoseinkhani research Center for Traditional Medicine and History of Medicine Shiraz University of Medical Sciences71348-14336 ShirazIran Student research committee Shiraz University of Medical Sciences71348-14336 ShirazIran

Objective: The use of traditional medicine and complementary alternative medicine(TM/CAM) derived from herbal remedies or natural supplements is increasing worldwide, but there are limited data on the use of TM/CAM during pregnancy. Iran has various ethnic populations, and the usage of TM/CAM by the different ethnic groups has not been researched. The aim of this study is to understand the use of TM/CAM modalities in pregnant women of different ethnic groups in southern ***: This study was conducted in primary health care centers in Khuzestan Province, Iran, from May to August, 2016. A semi-structured valid questionnaire was used to gather information in pregnant women(n = 170).Results: About 46.5% of women in this study used TM/CAM during previous pregnancies. The majority(67%) of study participants were Arab. The Arab population showed increased use of TM/CAM during pregnancy(P = 0.014). Women with complications in former pregnancies had significantly higher incidence rate of TM/CAM use(65.8%) compared to the other group(39.6%)(P = 0.001).Conclusion: Understanding TM/CAM use and the associated factors in different ethnic groups of pregnant women will benefit the evaluation of the proper health policies and mother-infant health programs. This study contributes to the growing literature on TM/CAM, ethnic diversity and pregnant women.

Preparation, characterization and in vivo evaluation of alginate-coated chitosan and trimethylchitosan nanoparticles loaded with PR8 influenza virus for nasal immunization

引用

Asian Journal of Pharmaceutical Sciences 2019年第2期14卷 216-221页

作者： Jafar Mosafer Amir-Hossein Sabbaghi Ali Badiee Solmaz Dehghan Mohsen Tafaghodi research Center of Advanced Technologies in Medicine Torbat Heydariyeh University of Medical Sciences School of Pharmacy Mashhad University of Medical Sciences Student research committee Mashhad University of Medical Sciences Nanotechnology research Center Pharmaceutical Technology Institute Mashhad University of Medical Sciences

For efficient mucosal vaccine delivery, nanoparticulate antigens are better taken by microfold cells in the nasal associated lymphoid tissue and also dendritic cells. Nanoparticles based on polymers such as chitosan(CHT) and its water soluble derivative, trimethylchitosan(TMC), could be successfully used as carrier/adjuvant for this purpose. Sodium alginate, a negatively charged biopolymer, could modify the immunostimulatory properties of CHT and TMC NPs and increase their stability. Sodium alginate(ALG)-coated chitosan(CHT)and trimethylchitosan(TMC) nanoparticles(NPs) loaded with inactivated PR8 influenza virus were successfully prepared by direct coating of the virus with CHT or TMC polymers to evaluate their immunoadjuvant potential after nasal immunization. After nasal immunizations in BALB/c mice, PR8-CHT formulation elicited higher IgG2 a and Ig G1 antibody titers compared with PR8-TMC. ALG coating of this formulation(PR8-CHT-ALG) significantly decreased the antibody titers and a less immune response was induced than PR8-TMC-ALG formulation. PR8-TMC-ALG formulation showed significantly higher Ig G2 a/Ig G1 ratio, as criteria for Th1-type immune response, compared with PR8-CHT-ALG and PR8 virus alone. Altogether, the PR8-TMC-ALG formulation could be considered as an efficient intranasal antigen delivery system for nasal vaccines.

Design high-performance narrowband emitters for blue light-emitting diodes through manipulating resonance structure of aromatic heterocycles

引用

Science China Chemistry 2025年

作者： Yue Yu Lei Xu Wenle Tan Yuyu Pan Jiyin Xiao Bohan Wang Guangjun Tian Yuguang Ma Lei Ying Institute of Polymer Optoelectronic Materials and Devices Guangdong Basic Research Center of Excellence for Energy and Information Polymer Materials State Key Laboratory of Luminescent Materials and Devices South China University of Technology School of Petrochemical Engineering Shenyang University of Technology Key Laboratory for Microstructural Material physics of Hebei Province School of Science Yanshan University

Narrowband light-emitting materials play critical roles in improving the color gamut and energy consumption of electroluminescence. Herein we demonstrated that by regulating the ground state resonance structure form of emitters with polycyclic aromatic heterocycles, the high-energy vibration of the C–C bond can be effectively suppressed, resulting in narrow emission like classical cyanine dyes. The designed compounds consist of twist and planar conformation, while having differences in the orientation of the positioning electron-donating(nitrogen) and electron-accepting(carbonyl) groups in the polycyclic aromatic hydrocarbon skeleton. The resulting compound Ac-Ph-Ac with a dominated zwitterionic resonance structure exhibits a relatively wide electroluminescent profile with the full width at half maximum(FWHM) of 42 nm and moderate device performance. In contrast, the “soliton transition” of 2AcPh based on the cyanine limit character effectively suppresses C–C stretching vibration in the polycyclic aromatic heterocycle skeleton, leading to a narrow electroluminescent profile with FWHM of 30 nm(0.16 eV)associated with an impressively high external quantum efficiency of 28.52%, which is among the highest efficiencies of so far reported non-sensitized organic light-emitting diodes.
