Assessing role of lipid and polymer based delivery systems in inserts

Majority of gynaecological, proctologic diseases were treated through rectal or vaginal delivery of medications, which can bypass the first pass metabolism and can produce required local effect. Inserts are evolutionary pharmaceutical dosageform that are semi solid at room temperature but upon insertion in cavities of humans, melt and release the drug localised. The inserts are advantageous since they can be placed at scare sites where blood perfusion is high that can enable for rapid absorption limiting many side effects. Ocular inserts represents the advanced technology in treating several ophthalmic diseases. Designing and development of optimum inserts is a challenge ever faced by Pharmaceutical researchers. In view of this, lipid and polymer based systems were additionally employed to improve the therapeutic efficiency of foresaid dosage forms. The review rationalises the importance of these inserts and their broad applications for multidisciplinary applications

Organochlorine insecticide residues in sediments from the coast of Chittagong, Bangladesh

A total of 5 samples of marine sediments were analyzed for residues of organochlorine insecticide from the coast of Chittagong, Bangladesh. The analytical method consisted of 3 phases, extraction, clean-up and, analysis through Gas Chromatography (GC) with Electron Capture Detector (ECD). The concentration ranges were as follows 0.18 - 1.33 ng.g¹ for aldrin, 0.2 - 1.84 ng.g¹ for dielddrin, 0.30 - 1.31 ng.g¹ for endrin, 0.11 - 0.26 ng.g¹ for lindane, 0.56- 3.36 ng.g¹ for heptachlor, 0.2- 1.51 ng.g¹ for P,P' DDE, 0.18- 2.91 ng.g¹ for P,P' DDD, 0.11 - 3.12 ng.g¹ for P,P' DDT. These results reveal that the sediments along coast of Chittagong are slightly contaminated with some of these organochlorine insecticides

Business of Fashion, Textiles & Technology: Summary Report: Mapping the UK Fashion, Textiles and Technology Ecosystem

The UK fashion, apparel and textiles industry is a globally competitive growth sector. The 2015 Value of Fashion report by Oxford Economics, commissioned by the British Fashion Council, found that the direct economic value of a flourishing sector including retail, manufacturing and textiles was £28.1 billion – and calculated its indirect impact at a further £22.6 billion, making a total contribution to gross domestic product of over £50 billion[3]. However, it is less well understood than other creative industries. The final product is generally perceived as catwalk-related in some way. In order to shift that perception, the Business of Fashion, Textiles and Technology (BFTT) report considers the fashion, textiles and technology industry as a wide range of intersecting sectors, spanning – quite literally – from agriculture to advertising. To date, the industry has been constrained by lack of innovation in business strategy and the late adoption of technology. These structural factors have severely limited investment in research, development and knowledge exchange within the broader Fashion, Textiles and Technology (FTT) ecosystem. Currently, the industry lacks robust data and compelling evidence compared to other creative industries regarding research and development (R&D) opportunities, business growth options, job creation and investment. Official data sources on the fashion industry are limited to ‘designer fashion’, which is conflated with ‘other design’ activity, and focuses on established brands and large retailers, and unrelated textiles manufacturers. In response to this deficit and to concerns around R&D, identified through the development of the BFTT creative R&D partnership proposal (2017), the BFTT’s first task was to launch a UK-wide survey of the FTT ecosystem (2019). Approximately one year later, the survey consultation (the launch of which preceded Covid-19 and Britain’s exit from the EU) had engaged over 2,400 small, medium and micro businesses (SMEs) and over 100 stakeholders and intermediaries, including industry specialists, trade bodies and workspace providers. The consultation received 814 survey responses and led to 65 stakeholder interviews, making it one of the most extensive baseline studies to date on FTT SMEs. BFTT surveyed and interviewed across the entire UK fashion and wider apparel value chain. Therefore, this report for the first time positions the UK sector as not weighted toward fashion only. It illustrates the textile, materials and technology elements as key parts of this ecosystem and shows the industry is highly heterogeneous, made up of intersecting textiles and technology companies that inform an array of multiple sectors

Ingestion efficiency of Macrobrachium rosenbergii (de Man) larvae feeding on Artemia, Moina micrura Kurz and their combination

Ingestion efficiency of Macrobrachium rosenbergii (de Man) larvae feeding on Artemia alone (A), Moina alone (M) and a 50:50 mixture of Artemia and Moina (AM) at 1, 3, 5 and 7 organisms ml-1 densities was investigated in terms of individual ingestion rate (IIR), dry mass ingestion (DMI) and energy intake (EI). Irrespective of larval stages and test food densities, larvae showed a significantly higher IIR for diet A except for AM, as the IIR for A and AM were similar from stage V onwards. Compared with diet A, IIR of M were sevenfold to fourfold lower, up to stage V. However, the larvae showed a sharp increase in IIR thereafter and gradually the differences reduced to about 1.6-1.2 fold at later stages. Despite the lower IIR, both DMI and EI for Moina were higher from stage VIII onwards than values for Artemia. In case of mixed diet (AM), the larvae of all stages showed a food selectivity response

Antipyretic activity of azima tetracantha in experimental animals

In the present study, the ethanolic leaf extract of Azima tetracantha Lam (A. tetracantha) was investigated for antipyretic activity in rats using Brewer’s yeast induced Pyrexia. The leaves of A. tetracantha were collected from Ponnamaravathi and cut into small pieces and shade dried. The dried powdered leaves (100 gm) were extracted in a Soxhlet apparatus by using 95% ethanol. Albino rats weighing (200-250g) were taken for the experiment divided into four groups of six animals each. Group 1 received 3% aqueous suspension of gum Acacia (1 ml/200g) as vehicle orally, group 2 and group 3 received ethanolic leaf extract of A. tetracantha 100 and 200 mg/kg with 3% aqueous suspension of gum Acacia orally and the group 4 served as standard received paracetamol 25 mg/kg with 3% aqueous suspension of gum Acacia orally. The subcutaneous injection of yeast suspension markedly elevated the rectal temperature after 18h of administration. Treatment with A. tetracantha extract at a dose of 100, 200 mg/kg decreased the rectal temperature of the rats in dose dependent manner. This effect was maximal at dose of 200 mg/kg and it caused significant lowering of body temperature (P< 0.01) up to 4 hour after its administration. The antipyretic effect started as early as 1h and the effect was maintained for 4h, after its administration. Both the standard drug paracetamol 25 mg/kg and tested drug A. tetracantha extract were significantly reduced the yeast elevated rectal temperature, at 2nd, 3rd and 4th hour compared to control group
