Inhibitory effects of the flavonoids isolated from Waltheria indica on the production of NO, TNF-alpha and IL-12 in activated macrophages. (1/12)
Three flavonoids were isolated from the whole plants of Waltheria indica and biological properties investigated. On the basis of their spectroscopic data, these compounds were identified as (-)-epicatechin, quercetin, and tiliroside. These flavonoids significantly and dose-dependently inhibited the production of the inflammatory mediator nitric oxide (NO), and the cytokines (tumor necrosis factor (TNF)-alpha and interleukin (IL)-12), in lipopolysaccharide (LPS) and interferon (IFN)-gamma activated murine peritoneal macrophages, without displaying cytotoxicity. The order of inhibitory activity was quercetin>tiliroside>(-)-epicatechin. Furthermore, peritoneal macrophages were pre-activated with LPS/IFN-gamma for 24 h, and the inhibitory effects of the above mentioned isolates on the production of NO were determined after a further 24 h, to address the possible mechanisms of their action. The present study supports the use of W. indica for the treatment of inflammatory diseases in traditional medicine. (+info)Antiviral effect of Guazuma ulmifolia and Stryphnodendron adstringens on poliovirus and bovine herpesvirus. (2/12)
Crude extract (CE) and aqueous (AqF) and ethyl acetate (EtOAcF) fractions of Guazuma ulmifolia Lam., Sterculiaceae and the corresponding AqF, EtOAcF of Stryphnodendron adstringens (Mart.) Coville, Leguminosae were tested for their antiviral activity against poliovirus 1 (P-1) and bovine herpesvirus 1 (BHV-1) in HEp-2 cultured cells. The antiviral activity was monitored by plaque assay and immunofluorescence assay (IFA) under virucidal and therapeutic protocols. The therapeutic protocol demonstrated statistically significant positive results with both plants and for both virus strains. The highest percentages of viral inhibition were found for G. ulmifolia EtOAcF which inhibited BHV-1 and P-1 replication by 100% and 99%, respectively (p<0.05, Student's t-test). For S. adstringens, AqF was the most efficient, inhibiting BHV-1 and P-1 by 97% and 93%, respectively (p<0.05). In the virucidal protocol, G. ulmifolia CE inhibited the replication of BHV-1 and P-1 by 60% and 26%, respectively (p<0.05), while, for S. adstringens, inhibition of 62% (p<0.05) was demonstrated only with EtOAcF for P-1. IFA demonstrated that the greatest reduction in fluorescent cell number occurred with G. ulmifolia, under the therapeutic protocol for both virus strains. However, AqF and EtOAcF of S. adstringens were most efficient with the virucidal protocol for P-1. In conclusion, we demonstrated that G. ulmifolia and S. adstringens inhibited BHV-1 and P-1 replication, as well as, blocked the synthesis of viral antigens in infected cell cultures. (+info)Distribution and frequency of galls induced by Anisodiplosis waltheriae Maia (Diptera: Cecidomyiidae) on the invasive plant Waltheria indica L. (Sterculiaceae). (3/12)
The frequency of galls induced by Anisodiplosis waltheriae Maia, a recently described species, on Waltheria indica L. was studied. W indica is an invasive weed in regeneration areas of Atlantic Forest in southeastern Brazil. Plants were collected in May 2004 and above-ground biomass, main stem length, number of leaves, number of galls per leaf and leaf area of each individual were recorded. Nearly 90% of all plants and 25% of all leaves were attacked by the gall midge, with an average of 0.67 galls/leaf. Leaf area had a weak effect on gall abundance while the number of leaves had no effect on gall abundance. Only 31% of the variation in gall abundance was explained by plant biomass. Natural enemies killed one third of the sampled galls. Predation accounted for 22.9% of gall mortality, unknown factors killed 7.6%, microhymenopteran parasitoids killed 2.5% and fungi only 1%. Mortality factors were not influenced by leaf area or gall density. (+info)Cucurbitacin B 2-sulfate and cucurbitacin glucosides from the root bark of Helicteres angustifolia. (4/12)
A new sulfated cucurbitacin, cucurbitacin B 2-sulfate (1) and a new cucurbitacin glucoside, cucurbitacin G 2-O-beta-D-glucopyranoside (2) together with two known cucurbitacin glucosides, arvenin I and arvenin III were isolated from the root bark of Helicteres angustifolia. The structures of these compounds were established on the basis of spectroscopic and chemical evidence. These four compounds taste of strong bitterness. Compound 1 is a first sulfated cucurbitacin found in plants. (+info)Anti-estrogenic activity of mansorins and mansonones from the heartwood of Mansonia gagei DRUMM. (5/12)
Through an anti-estrogenic bioassay-guided fractionation of the methanol extract of Mansonia gagei, three new coumarins, called mansorins I (1), II (2) and III (3) and a new naphthoquinone, mansonone I (4), were isolated. Their structures were determined based on their NMR data and CD spectroscopy. The anti-estrogenic activity of the fractions and the isolated compounds were investigated using a yeast two-hybrid assay method expressing estrogen receptors alpha (ERalpha) and beta (ERbeta). In addition, an ERalpha competitor screening system (ligand binding screen) was used to verify the binding affinities of the isolated compounds to the estrogen receptor. 1,2-Naphthoquinones (mansonones) showed more binding affinities to ER in both assay systems. All the tested compounds showed higher binding affinities to ERbeta than to ERalpha in the yeast two-hybrid assay. Mansonones F and S showed the most potent estrogen binding and estrogen antagonistic effects.

(+info)Sterculiaceae is a former family of flowering plants that is now classified as a subfamily (Sterculioideae) within the family Malvaceae, according to the Angiosperm Phylogeny Group IV system. This group includes several genera of trees and shrubs, many of which have tropical distributions. Some well-known members of this subfamily include Sterculia, Cola, and Ficus (which contains various fig tree species). These plants are characterized by their typically large, simple leaves and showy flowers with numerous stamens. The fruits of Sterculiaceae are diverse in form, ranging from capsules to berries or schizocarps.
Brachiaria is a genus of tropical and subtropical grasses that are native to Africa, but have since been introduced and naturalized in many other parts of the world. They are important pasture grasses for grazing livestock, particularly in areas with low soil fertility and high temperatures. Some species of Brachiaria have also been found to have potential as cover crops and for erosion control.
There is no medical definition of 'Brachiaria' as it is a term used in botany and agriculture, not medicine.
Clinical laboratory services refer to the tests and examinations performed on samples of patient’s bodily fluids, tissues, and other substances to assist in diagnosing, monitoring, and treating medical conditions. These services are typically provided by specialized laboratories that use various analytical methods and technologies to examine clinical specimens.
The tests conducted by clinical laboratory services can include hematology, chemistry, microbiology, immunology, molecular biology, toxicology, and urinalysis, among others. The results of these tests provide critical information to healthcare providers for the diagnosis, treatment, and management of various medical conditions, including infections, genetic disorders, hormonal imbalances, nutritional deficiencies, and cancer.
Clinical laboratory services play a vital role in modern healthcare systems, providing accurate and timely diagnostic information that helps improve patient outcomes, reduce healthcare costs, and enhance the quality of care.
I'm sorry for any confusion, but "Switzerland" is not a medical term or concept. Switzerland is a country in Europe, known officially as the Swiss Confederation. If you have any questions about medical terminology or concepts, I'd be happy to try and help answer those for you!
"Penicillium" is not a medical term per se, but it is a genus of mold that is widely used in the field of medicine, specifically in the production of antibiotics. Here's a scientific definition:
Penicillium is a genus of ascomycete fungi that are commonly found in the environment, particularly in soil, decaying vegetation, and food. Many species of Penicillium produce penicillin, a group of antibiotics with activity against gram-positive bacteria. The discovery and isolation of penicillin from Penicillium notatum by Alexander Fleming in 1928 revolutionized the field of medicine and led to the development of modern antibiotic therapy. Since then, various species of Penicillium have been used in the industrial production of penicillin and other antibiotics, as well as in the production of enzymes, organic acids, and other industrial products.
I apologize for any confusion, but "Ajuga" is not a medical term. It is actually the name of a genus of plants in the mint family, also known as bugleweed. These plants have been used in traditional medicine to treat various conditions such as anxiety, sleep disorders, and skin irritations. However, it's important to note that the use of herbal remedies should always be discussed with a healthcare provider beforehand, as they can interact with other medications or have unintended side effects.
Cellulases are a group of enzymes that break down cellulose, which is a complex carbohydrate and the main structural component of plant cell walls. These enzymes are produced by various organisms, including bacteria, fungi, and protozoa. They play an important role in the natural decomposition process and have various industrial applications, such as in the production of biofuels, paper, and textiles.
Cellulases work by hydrolyzing the beta-1,4 glycosidic bonds between the glucose molecules that make up cellulose, breaking it down into simpler sugars like glucose. This process is known as saccharification. The specific type of cellulase enzyme determines where on the cellulose molecule it will cleave the bond.
There are three main types of cellulases: endoglucanases, exoglucanases, and beta-glucosidases. Endoglucanases randomly attack internal bonds in the amorphous regions of cellulose, creating new chain ends for exoglucanases to act on. Exoglucanases (also known as cellobiohydrolases) cleave cellobiose units from the ends of the cellulose chains, releasing cellobiose or glucose. Beta-glucosidases convert cellobiose into two molecules of glucose, which can then be further metabolized by the organism.
In summary, cellulases are a group of enzymes that break down cellulose into simpler sugars through hydrolysis. They have various industrial applications and play an essential role in natural decomposition processes.
