Microalgal Species

Abstract: More than 90% of herbal products and herbal medicines have been derived from higher plants recently, but due to independent circumstances, several photosynthetic microalgal species are in focus in this point of view. In the last 50 years, many carbohydrate-, peptide-, terpenoid-, alkaloid- and phenol-type components were described from algae because of the developing structural determination and analytical methods, algae mass production and also artificial algae technologies. At the same time, based partly on traditional causes and partly on the clinical and preclinical data of today, some dried products of algae are directly used as food supplements. Hereinafter, the historical background, economic significance and metabolic background of the mostly used microalgal species will be reviewed. The diverse metabolite production of these organisms will be demonstrated by some molecules with special bioactivity. Several preclinical and clinical studies will be described relating to the microalgal species Spirulina sp., Chlorella sp., Haematococcus sp. and Dunaliella sp. Orv Hetil. 2018; 159(18): 703–708.

Algal Chloroplast

: In recent years, microalgae have emerged as an alternative platform for large-scale production of recombinant proteins for different commercial applications. As a production platform, it has several advantages, including rapid growth, easily scale up and ability to grow with or without the external carbon source. Genetic transformation of several species has been established. Of these, Chlamydomonas reinhardtii has become significantly attractive for its potential to express foreign proteins inexpensively. All its three genomes – nuclear, mitochondrial and chloroplastic – have been sequenced. As a result, a wealth of information about its genetic machinery, protein expression mechanism (transcription, translation and post-translational modifications) is available. Over the years, various molecular tools have been developed for the manipulation of all these genomes. Various studies show that the transformation of the chloroplast genome has several advantages over nuclear transformation from the biopharming point of view. According to a recent survey, over 100 recombinant proteins have been expressed in algal chloroplasts. However, the expression levels achieved in the algal chloroplast genome are generally lower compared to the chloroplasts of higher plants. Work is therefore needed to make the algal chloroplast transformation commercially competitive. In this review, we discuss some examples from the algal research, which could play their role in making algal chloroplast commercially successful.

Background: Common auto-inflammatory disorders (CAIDs) constitute a wide array of ailments ranging from acute allergies to chronic conditions. Globally, CAIDs remain one of the leading causes of disability and morbidity. Despite playing a leading therapeutic role, the vast profusion of anti-inflammatory synthetic agents have not been able to fully resolve a panoply of CAIDs. Additionally, contemporary synthetic therapy approaches remain bounded by a wide array of limitations essentially being adverse effects and unaffordable costs. In this advent, the use of herbal products provides an interesting avenue to explore in view of developing such treatment regimens. Objective: This review article endeavors to highlight potential herbal products and isolated phytochemicals which can be of benefit in the prophylaxis, management, and treatment alongside avoiding the relapse of CAIDs. Conclusion: This review article has highlighted that herbals, herbal products, and isolated metabolites hold a huge potential in the prophylaxis, management, and treatment of CAIDs. Herbals can act on various targets involved in the pathogenesis of inflammatory disorders. In addition, novel approaches for the management of CAIDs are numerous. Indeed, nanoparticles loaded with phytochemicals have been developed to specifically target the colon for IBD treatment. In silico approaches using herbals also offer unlimited avenues to decipher new pharmacophores. Investigating the potential of polyherbal formulations is another unique approach which can be investigated. Given the inefficacy of conventional medicines, the concomitant use of conventional and herbal medicines can also be explored.

Currently in Europe, despite the many advances in production technology of synthetic drugs, the interest in natural herbal medicines continues to increase. One of the reasons for their popular use is the assumption that natural equals safe. However, herbal medicines contain pharmacologically active ingredients, some of which have been associated with adverse effects. Kidneys are particularly susceptible to injury induced by toxins, including poisonous constituents from medicinal plants. The most recognized herb-induced kidney injury is aristolochic acid nephropathy connected with misuse of certain Traditional Chinese herbal medicines. Data concerning nephrotoxicity of plant species of European origin are scarce. Here, we critically review significant data of the nephrotoxicity of several plants used in European phytotherapy, including Artemisia herba-alba, Glycyrrhiza glabra, Euphorbia paralias, and Aloe). Causative mechanisms and factors predisposing to intoxications from the use of herbs are discussed. The basic intention of this review is to improve pharmacovigilance of herbal medicine, especially in patients with chronic kidney diseases.

Animal toxins and venoms have recently been developed as cancer treatments possessing tumor cell growth-inhibitory, antiangiogenesis, and proapoptotic effects. Endometriosis is a common benign gynecological disorder in reproductive-age women, and no definite treatment for this disorder is without severe side effects. As endometriosis and malignant tumors share similar characteristics (progressive, invasive, estrogen-dependent growth, and recurrence), animal toxins and venoms are thought to be effective against endometriosis. The objective of this study was to outline studies using toxic animal-based medicinal materials (TMM) as endometriosis treatment and to explore its clinical applicability. Preclinical and clinical studies using TMM were searched for in four databases from inception to October 2020. A total of 20 studies of TMM on endometriosis were included. In eight clinical studies, herbal medicines containing TMM were effective in relieving symptoms of endometriosis, with no side effects. In twelve experimental studies, the main therapeutic mechanisms of TMM against endometriosis were proapoptotic, antiangiogenesis, estrogen level-reducing, and possible anti-inflammatory effects. TMM are thus considered promising sources for the development of an effective treatment method for endometriosis. Further studies are needed to clarify the therapeutic mechanism of TMM against endometriosis and to provide sufficient grounds for clinical application.

This contribution deals with the evolution of public finance in two selected European countries. France and Germany were selected as countries to compare their evolution of public finance. The reason why the two countries were chosen is their general proximity to each other in many respects. From a professional point of view, i.e. from the point of view of the discipline of public finance, however, these are countries with different concepts of public finance disciplines. The contribution presents the historical background, context and consequences of this evolution. The relevant public finance evolution is divided into several historical stages in each country. The contribution focuses on each stage separately and points out solutions and effect of each stage. The main aim of the contribution is to confirm or disprove the hypothesis that the evolution of the public finance discipline was different in each of the selected countries. The scientific methods used in the article are analysis and synthesis, description and comparative methods.

Diabetes mellitus is one of the most common metabolic disorders associated with disturbed hormonal secretion. Diabetes is characterized by high blood glucose levels over a prolonged period of time. High sugar levels are due to abnormal metabolism of carbohydrates and lipids which is caused by absolute or relative insulin deficiency. Herbal medicines have been the highly esteemed source of medicine throughout the human history. Herbs are becoming more popular today because of their least side effects, holistic beliefs, easy availability and low cost. Individual herbal products and formulations are gaining popularity because of their quality manufacturing using modern analytical techniques and standardized raw materials. Herbal drugs are widely used for the treatment of diabetes worldwide in various dosage forms. India has a long list of native herbal drugs with scientifically proven blood sugar lowering properties. The seeds of Nigella sativa, Olea europaea, fruits of Aegle marmelos, Momordica charantia, Coccinia indica, Nigella sativa,Gymnema sylvestre leaves,whole plant of Pterocarpus marsupium, Syzygium cumini fruits, Swertia punicea, Urtica dioica, gum of Ferula assa-foetida and seeds of Trigonella foenum graecum were discussed along with their reported mechanisms of action. In this review paper an attempt has been made to give an overview of certain Indian plants which have shown their anti-diabetic activity in various pre-clinical studies.

Early Design Stage

Abstract Design for manufacturing (DFM) strategies help companies to develop new products that are feasible to manufacture. In the early stages of design all engineering activities are initiated in computer aided systems. When the design is finished, the process of manufacturing and production planning begins. Issues often occur at this point because two teams, designers and manufacturers, have been working separately. The resulting question is: ‘how can Knowledge Engineering (KE) be used effectively to enhance manufacturability during early design?’ Even if the most complex geometrical product can be realized using today’s technologies such as rapid prototyping it is only true in unit production. In lot and mass production where CNC machines are used, complex geometry causes a number of difficulties. So it is important to investigate the project carefully in the early design stage from the point of view of whether it will be possible to manufacture.

Aristolochic acid nephropathy (AAN) is a rapidly progressive renal disease caused by the ingestion of plant products containing aristolochic acid (AA), first described in connection with the use of Chinese herbal medicines. Although the true worldwide extent of this disease is unknown, it is likely to represent a significant cause of chronic kidney disease (CKD) in many parts of the world. Furthermore, recent data have also demonstrated that AA is also the primary aetiological agent in Balkan endemic nephropathy. AAN is notable in its association with urothelial malignancy, with the mechanisms of carcinogenesis now well characterized. Aside from a possible role for corticosteroid therapy in slowing disease progression in selected patients, no disease-specific treatments have yet been shown to alter the course of this nephropathy. Therefore, prevention of exposure to AA and, in affected patients, effective management of the risk of malignancy are key principles in the approach to this condition. Although preparations containing Aristolochia spp. and herbs that can be confused or substituted for Aristolochia have been banned in many countries, other herbal products containing AA have continued to be available to consumers long after these bans have been instituted, highlighting the ongoing need for awareness of this disease.
