The study was designed to evaluate the role of various plant polyamines (PAs) on in-vitro multiplication and regeneration in the Ayurvedic memory enhancer Bacopa monnieri (L.) Wettst. Natural populations of B. monnieri were collected, sterilized and micropropagated in Murashige and Skoog (MS) me...

Bacopa monnieri (Brahmi) is a high value herbaceous medicinal species used for improving intellect and memory. In India, high demand of B. monnieri for the manufacture of herbal extracts and medicines prompts its collection in huge quantities from wild habitats, leading to the extinction of its ...

Reactive oxygen species (ROS) may be involved in the pathogenesis of serum induced by dichlorvos. Therefore, the rationale of present research was to evaluate the ameliorative efficacy of bacoside A and bromelain on oxidative stress biomarkers in serum of dichlorvos intoxicated mice. Also the le...

Current study established a protective action of bacoside A and bromelain against the toxic effects of dichlorvos in kidneys of mice. Experimental design included five groups. The first group was control. Mice of groups II, III and IV were administered doses of dichlorvos, bromelain and bacoside...

Cardiovascular diseases are one of the major global health issues leading to morbidity and mortality across the world. In the present study Bacopa monniera and its major bioactive component, Bacoside A (Bac-A) was used to evaluate its cytoprotective property in H9C2 cardiomyocytes against tBHP (...

Chronic inflammation of the myelin sheath is the crucial event behind the progression of multiple sclerosis (MS). Bacoside-A is one of the major constituents obtained from Bacopa monerii (L.) Wettst., and possess neuroprotective as well as anti-inflammatory actions. The current study explores th...

Due to its important role in regulating angiogenesis, vascular homeostasis and remodeling, and arteriogenesis in blood vascular and lymphatic endothelial cells, VEGFR2 stimulation has demonstrated promise in preclinical studies as an endovascular treatment for ischemic myocardial and peripheral ...

Agnuside despite its good properties for the body, can be harmful to the kidneys in extra concentrations. So, its measurement is important. For the first time, we developed a simple, rapid and inexpensive method for the investigation of agnuside electrochemical behavior by designing a gold/reduc...

Isolated root cap cells can be used to study the effects of victorin on large populations of intact oat cells. The isolation of oat root cap protoplasts allowed a comparison of victorin-induced death of cells, with or without cell walls. Isolated root cap cells and protoplasts were incubated at ...

Victorin is a host-selective toxin produced by Cochliobolus victoriae the causal agent of victoria blight of oats. Victorin-binding and biochemical analyses have implicated the glycine decarboxylase complex (GDC), a key component of the photorespiratory cycle, as a possible site of action of the...

SummaryThe host-specific phytotoxin victorin was purified from culture filtrates of Bipolaris victoriae by solvent extraction, alumina adsorption chromatography and reverse phase high-pressure liquid chromatography (HPLC). Victorin activity was associated with an HPLC fraction containing a peak ...

Veramyosides A-J, eleven undescribed stigmastane-type steroids, including one aglycone and ten glycosides, along with three known homologues were isolated from the twigs of Vernonia amygdalina Delile (compositae). All compounds featured a stigmastane-type steroid skeleton with a unique conjugate...

The effect(s) of 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3] on fracture healing was studied in a vitamin D-depleted chick model. 24R,25(OH)2D3, together with another hormonally active vitamin D metabolite, 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3], improved bone mechanical strength parameters (...

The kidney is the major source of the circulating dihydroxylated metabolites of vitamin D, 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3] and 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3]. The enzymes which catalyze the production of these two dihydroxylated vitamin D metabolites are the 25(OH)D3-1α-h...

Measurement of serum 25-hydroxyvitamin D [25(OH)D] is considered the best indicator of vitamin D status. Two minor vitamin D metabolites are common interferences encountered in 25(OH)D assays. The first is 3-epi-25-hydroxyvitamin D3 [3-epi-25(OH)D3], which if not chromatographically resolved fro...

Previously we showed that costochondral growth plate resting zone (RC) chondrocytes response primarily to 24R,25(OH)2D3 whereas prehypertrophic and hypertrophic (GC) cells respond to 1α,25(OH)2D3. 24R,25(OH)2D3 increases RC cell proliferation and inhibits activity of matrix processing enzymes, ...

BackgroundEpidemiological studies indicate high serum 25(OH)D3 is associated with increased survival in breast cancer patients. Pre-clinical studies attributed this to anti-tumorigenic properties of its metabolite 1α,25(OH)2D3. However, 1α,25(OH)2D3 is highly calcemic and thus has a narrow the...

A fluorometric assay was developed to semi-quantify co-purified polyketide prymnesins-1 and -2 (PPs) from Prymnesium parvum cultures. Evaluations performed throughout the growth cycle of 5 practical salinity unit (PSU) cultures detected relatively 8–10 × more PPs in the culture medium (exotoxi...

Harmful blooms formed by planktonic microalgae (HABs) in both freshwater and coastal waters regularly lead to severe mortalities of fish and invertebrates causing substantial economic losses of marine products worldwide. The mixotrophic haptophyte Prymnesium parvum is one of the most important m...

A suite of glycosylated glycerol derivatives representing various fragments of the glycosylated ichthyotoxins called prymnesins were chemically synthesised. Glycerol was used to represent a small fragment of the prymnesin backbone, and was glycosylated at the 2° position with the sugars current...
