The effect of four extracts from neem seeds (Azadirachta indica) containing 2000, 5000, 9000 and 10,000 ppm of azadirachtin A (AZA), quantified by high-performance liquid chromatography (HPLC) and diluted to 1.25%; 2.5%; 5.0%; 10.0% and 12.8% was verified by in vitro tests with engorged females and larvae of the cattle tick Rhipicephalus microplus. The results from the bioassays with the engorg...

The exchange rate plays an essential role for firms which export goods and import raw materials. In this paper, the effects of real specific exchange rate fluctuations in imports, exports and aggregate trade on industry sector, chemical and transportation industries outputs in 49 OIC countries were investigated by using a panel data model over 1990-2014. Particularly, this paper presents eviden...

In order to achieve prolong corneal contact time of norfloxacin(NFX) for treatment of extra ocular diseases, a pH triggered nanoparticulate in situ gelling system was designed to explore dual advantage of nanoparticles and in situ gelling system, for its ocular delivery. NFX loaded nanocarriers were developed by ionotropic gelation technique using chitosan as a matrix forming polymer, cross-lin...

The effect of culture conditions on the glutamylation of methotrexate by intact H35 hepatoma cells and folylpolyglutamate synthetase (FPGS) activity in the corresponding crude extracts has been examined. The rate of cellular glutamylation of methotrexate observed in rapidly dividing cultures was 4-fold higher than confluent cultures, and was accompanied by an increase in extract FPGS activity (...

Abstract This retrospective study examines involvement in school bullying at all developmental stages, from elementary to university, relation personality traits. Participants were 216 university students, 162 (75.0%) females and 54 (25.0%) males. The majority of the sample (88.9%) aged 18–24. Students completed International Personality Items Pool (BFFM) a self-report questionnaire about onlin...

Bee pollen is a rich bee product, from the point of view its nutritional and functional chemical characteristics. The composition properties make this product an excellent food supplement for human diet, due to various bioactivities, such as having antioxidant, antibacterial, antifungal, anti-inflammatory properties. These depend on botanical origin pollen. Castanea sativa one most important ty...

A measurement campaign of particle number concentration and size distribution was conducted at urban (SYSU) suburban (Panyu) areas Guangzhou, South China, during 16 January to 3 February 2020 before the Chinese New Year (CNY) holiday. Average (PNC) 6.3 × 103 cm-3 9.7 cm-3, respectively, sites, indicating severe particulate matter (PM) pollution. The PNC in region influenced by monsoon land–sea ...
