Opis:
Hyssopus officinalis L. is a medicinal plant containing valuable phytochemicals and is used extensively in the pharmaceutical industry. As this plant naturally contains low levels of these metabolites, plant cell and tissue culture technologies are used to produce them in large volumes. The present study aimed first to evaluate the effects of different types of cytokinins, including benzyl adenine (BA), kinetin (KIN), and thidiazuron (TDZ), at 1 ppm concentration in the culture medium on growth parameters and production of secondary metabolites and photosynthetic pigments in organ culture of H. officinalis; in the second step, the study investigated the effect of different concentrations (0, 0.2, 1, 1.5, and 2 ppm) of the most effective type of cytokinin. The results showed that TDZ was the optimal type of growth regulator compared to BA and KIN as it showed a positive influence on the studied traits; furthermore, its highest concentration of 2 ppm in culture medium was determined to be the best one that enabled the highest production of secondary metabolites and photosynthetic pigments. We conclude that the presence of growth regulators can strongly influence the growth and development of plants in tissue culture conditions.

Opis:
Inonotus obliquus is a parasite on the birch and other trees and is also a well-known medicinal mushroom. Its sterile conk is highly sought for its bioactive compounds such as phenols, polysaccharides, triterpenoids, and steroids. It was traditionally used to treat various gastrointestinal diseases, viral and parasitic infections, to counteract the progression of cancers, and to stimulate the immune system. We used acute gamma irradiation, followed by short-term submerged cultivation, as an oxidative stress inducer to enhance the synthesis of mycelial metabolites. The 300 Gy and 400 Gy doses showed the best results across the whole experimental design. Each assayed criterion had a different corresponding optimal stimulation dose. In one experiment, sublethal doses of irradiation triggered the dry weight of the cultured mycelium to increase by 19.764%. The free radical scavenging potential of the mycelium extracts increased by 79.83%. The total phenolic content of mycelium extracts and culture broth increased by 55.7% and 62.987%, respectively. The total flavonoid and sinapinic acid content of the broth increased by 934.678% and 590.395%, respectively. As such, gamma irradiation pretreatment of the mycelial inoculum proved an interesting, economically and environmentally effective tool for stimulating secondary metabolite synthesis in submerged mycelium cultures.

Opis:
Epicoccum nigrum Link is well known for producing biologically-active substances with activities against prokaryotic and eukaryotic cells. The major goal of this study was to assess E. nigrum as a potential in vitro agent against selected species of dermatophytes. The effects of the types of media used in this study on the interactions between the microscopic fungi were also examined. Epicoccum nigrum’s bioactive metabolites exhibited a strong growth inhibitory effect against the dermatophytes, suggesting its potential as a biocontrol agent. Notably, the strength of these interactions was dependent on the type of the medium. These secondary metabolites are not toxic against the higher eukaryotic organisms, which was further demonstrated by using the Galleria mellonella model.

Opis:
Root-knot nematodes, genus Meloidogyne, are among the most plant damaging pathogens worldwide. The action of natural products against plant pathogens has been investigated to assess their effectiveness in the control of diseases. Thus, the present study aimed to evaluate the phytochemistry potential of the Ficus species for the control of Meloidogyne javanica. In vitro inhibitory activity assays were performed with crude ethanolic extracts of leaves and branches from 10 Ficus species. Among these, Ficus carica extracts exhibited strong paralysis activity against second stage juveniles (J2) (EC50 = 134.90 μg ∙ ml–1 ), after 72 hours. In addition, high efficacy was observed in egg-hatching inhibition at different embryonic stages. Microscopy analysis revealed severe morphological alterations in the nematode tissues at the J2 stage, as well as immotility of juveniles released from eggs in the presence of F. carica extracts. The efficacy of the treatments for the other species was very low. These differences were supported by the variation in the compound classes, mainly for alkaloids and metabolite profiles by Gas Chromatography/Mass Spectrometry (GC/MS) when F. carica was compared with the other species. The results indicated that F. carica is a promising source for the isolation and identification of molecules capable of acting in the control of M. javanica.

Opis:
The aim of the study was to investigate the influence of plant growth regulators on callus culture of common thyme (Thymus vulgaris L.) and the possibility of using such callus cultures to obtain rosmarinic acid. The explants used to initiate shoot culture were the seeds of common thyme. The seeds were individually placed into test tubes with MS culture media of macro- and micro-element content according to Murashige and Skoog (1962). For the purpose of initiation of cultures, leaves dissected along the vascular bundle were used. The leaves were placed on MS medium with the addition of BAP in combination with NAA in a concentration of 3 and 5 mg•dm-3. Propagation of callus cultures was conducted with the use of fragments of callus tissue placed on MS media supplemented with BAP used separately in a concentration of 3 mg•dm-3, and in combination with NAA (1, 2, 3 mg•dm-3) and 2,4-D in a concentration of 0.5, 1 or 1.5 mg•dm-3 respectively. In each stage of the experiment, explants placed on MS media without the addition of plant growth regulators were the control. It was found that initiation of common thyme cultures should be conducted on MS media without plant growth regulators. For the purpose of initiation of callus culture of common thyme, the optimal culture medium was MS with the addition of 3 mg•dm-3 BAP and NAA. Propagation of callus tissue of common thyme should be conducted on culture media supplemented with 3 mg•dm-3 BAP used in combination with 1 mg•dm-3 NAA. It was observed that the mass of the propagated callus tissue decreased with an increase of NAA content.

Background: Dengue is one of the major public health problems in the world, affecting more than fifty million cases in tropical and subtropical region every year. The metabolome, as pathophysiological end-points, provide significant understanding of the mechanism and progression of dengue pathogenesis via changes in the metabolite profile of infected patients. Recent developments in diagnostic technologies provide metabolomics for the early detection of infectious diseases. Methods: The mid-stream urine was collected from 96 patients diagnosed with dengue fever at Penang General Hospital (PGH) and 50 healthy volunteers. Urine samples were analyzed with proton nuclear magnetic resonance (1H NMR) spectroscopy, followed by chemometric multivariate analysis. NMR signals highlighted in the orthogonal partial least square-discriminant analysis (OPLS-DA) S-plots were selected and identified using Human Metabolome Database (HMDB) and Chenomx Profiler. A highly predictive model was constructed from urine profile of dengue infected patients versus healthy individuals with the total R2Y (cum) value 0.935, and the total Q2Y (cum) value 0.832. Results: Data showed that dengue infection is related to amino acid metabolism, tricarboxylic acid intermediates cycle and β-oxidation of fatty acids. Distinct variations in certain metabolites were recorded in infected patients including amino acids, various organic acids, betaine, valerylglycine, myo-inositol and glycine. Conclusion: Metabolomics approach provides essential insight into host metabolic disturbances following dengue infection.

Opis:
The impact of health and environmental hazards, associated with the constituents of gasoline, on occupationally exposed workers has been recorded over the past few decades. However, the scientific literature on their pathogenic potential remains incomplete, which could affect the current understanding of the associated health risks. This review provides current information based on recently improved research techniques to evaluate gasoline toxicity profiles for humans. Our current knowledge provides insight into the intricate mechanism of gasoline-induced adverse effects, including the formation of reactive metabolites via bio-activation and subsequent generation of reactive oxygen species (ROS) and oxidative stress, which are involved in multiple mechanisms that are central to the aetiology of gasoline-induced toxicity. These mechanisms include covalent binding to deoxyribonucleic acid (DNA), leading to oxidative damage, tumor-suppression gene activity, and activation of pro-oncogenes. Furthermore, it results in induction of autoimmunity and local inflammatory responses, disruption of multiple neurotransmitters and immune cell function, derangement of various enzyme activities (e.g., sodiumpotassium adenosine triphosphate (Na+/K+/ATPase) activity, cytochrome P450 (CYP450), nitric oxide synthase (NOS), antioxidant enzyme activities, etc.), conjugation of bile, and non-specific cell membrane interaction, leading to damage of the membrane lipid bilayer and proteins. Available data suggests that exposure to gasoline or gasoline constituents have the potential to cause different types of illnesses. The data highlights the need to maintain safety measures via suitable research, medical surveillance, regulatory control, life style modification, early detection, and intervention to minimize exposure and manage suspected cases. They also present novel opportunities to design and develop effective therapeutic strategies against gasoline-induced detrimental effects. Int J Occup Med Environ Health 2017;30(1):1–26

Opis:
Twinflower (Linnaea borealis L.) is a widespread circumboreal plant species belonging to Linnaeaceae family (previously Caprifoliaceae). L. borealis commonly grows in taiga and tundra. In some countries in Europe, including Poland, twinflower is protected as a glacial relict. Chemical composition of this species is not well known, however in folk medicine of Scandinavian countries, L. borealis has a long tradition as a cure for skin diseases and rheumatism. It is suggested that twinflower has potential medicinal properties. The new study on lead secondary metabolites responsible for biological activity are necessary. This short review summarizes very sparse knowledge on twinflower: its biology, distribution, conservation status, chemical constituents, and describes the role of this plant in folk tradition of Scandinavian countries.
Zimoziół północny (Linnaea borealis L.) jest szeroko rozpowszechnionym gatunkiem cyrkumborealnym, należącym do rodziny Linnaeaceae (wcześniej Caprifoliaceae). Licznie rośnie w tajdze i tundrze. W kilku krajach Europy, także w Polsce, zimoziół został objęty ochroną gatunkową jako relikt glacjalny. W medycynie ludowej krajów skandynawskich L. borealis cieszy się długą tradycją stosowania w chorobach skórnych i reumatycznych, co wskazuje na potencjalne właściwości lecznicze omawianego gatunku. Jego profil chemiczny jest słabo poznany, dlatego wskazane są nowe badania głównych metabolitów wtórnych, które mogą być odpowiedzialne za aktywność biologiczną surowca. Niniejszy artykuł stanowi krótki przegląd dostępnej literatury, podsumowując skromną wiedzę na temat L. borealis z zakresu biologii, występowania, ochrony gatunku, obecności związków czynnych, stosowania w medycynie tradycyjnej i miejsca tego gatunku w kulturze krajów skandynawskich.

Opis:
Capsaicinoids are secondary metabolites characteristic of plants of the genus Capsicum and are only found in the pepper fruit. Their biosynthesis occurs mainly in the placental cells as well as in the interlocular septa of the fruit. In the present study, the content of capsaicinoids (capsaicin and dihydrocapsaicin) was determined by HPLC in two hot pepper cultivars (‘Orkan’ and ‘Bronowicka Ostra’), identifying the percentage of these compounds in the whole fruit and in the following fruit parts: placenta, seeds, pericarp, and pedicle. Significantly more capsaicinoids were found in ‘Bronowicka Ostra’ peppers (262 mg∙kg⁻¹) compared to ‘Orkan’ peppers (175 mg∙kg⁻¹). The highest capsaicin and dihydrocapsaicin content was found in the placenta (401 mg∙kg⁻¹). The capsaicin content in the whole fruit and its parts is on average more than 10 times higher in relation to the dihydrocapsaicin content. Fruit harvest time contributes to the differences in the capsaicinoid content in the individual fruit parts. A higher capsaicin content was shown in the pericarp and seeds, while the dihydrocapsaicin content was higher in the pedicle of peppers harvested at the later date.
Kapsaicynoidy są metabolitami wtórnymi charakterystycznymi tylko dla roślin z rodzaju Capsicum i występują tylko w owocach papryki. Ich biosynteza zlokalizowana jest głównie w komórkach łożyska oraz w przegrodach nasiennych owoców. W niniejszej pracy metodą HPLC oznaczono zawartość kapsaicynoidów (kapsaicyny i dihydrokapsaicyny) w całych owocach i w ich częściach: łożysku, nasionach, perykarpie oraz szypułce dwóch odmian papryki ostrej: Orkan i Bronowicka Ostra. Istotnie więcej kapsaicynoidów oznaczono w owocach odmiany Bronowicka Ostra (262 mg∙kg⁻¹) w porównaniu z owocami odmiany Orkan (175 mg∙kg⁻¹). Największą zawartość kapsaicyny i dihydrokapsaicyny stwierdzono w łożysku (401 mg∙kg⁻¹). Zawartość kapsaicyny w całych owocach oraz w poszczególnych ich częściach była średnio ponad 10-krotnie większa porównaniu z zawartością dihydrokapsaicyny. Terminy zbioru owoców miał wpływ na zróżnicowanie zawartości kapsaicynoidów w poszczególnych częściach owoców. Większą zawartość kapsaicyny wykazano w perykarpie oraz nasionach, a dihydrokapsaicyny w szypułkach owoców z późniejszego terminu zbioru.
