Increasing evidence supports a link between multiple system atrophy and coenzyme Q10 (CoQ10) biosynthesis. However, so far this knowledge was not translated into tangible benefits for affected patients. Poor bioavailability of oral CoQ10 might constitute a major problem. Current research suggests
The clinical phenotypes of human CoQ10-deficiency caused by COQ2 mutations range from fatal neonatal disease to adult-onset multisystem atrophy. So far, treatment options for these diseases are unsatisfactory. Here, we demonstrate that supplementation of 4-hydroxybenzoic acid (4-HBA) fully restores
Glutamate and nitric oxide (NO) are important regulators of dendrite and axon development in the central nervous system. Excess glutamatergic stimulation is a feature of many pathological conditions and manifests in neuronal atrophy and shrinkage with eventual neurodegeneration and cell death. Here
The impact of treating astrocytes with the astrocytic toxin l-alpha amino adipic acid (L-AAA) on neuronal outgrowth, complexity and synapse formation was assessed, using a model of astrocyte-neuronal interaction. Treatment of rat primary cortical neurons with conditioned media (CM) derived from
The effect of aspirin on dopaminergic neuronal damage induced by in vivo infusion of 1-methyl-4-phenylpiridinium iodide (MPP(+)) and 6-hydroxydopamine (6-OHDA) was studied in rats, using microdialysis. Rat striata were perfused with 1 mM MPP(+) or 6-OHDA for 10 min, causing peak levels of dopamine
Pathogenic fungi and oxidation are the major factors that cause the deterioration of sweet potatoes and also cause the loss of quality that makes consumption unsafe. In the present study, the in vitro results demonstrate that the essential oil from sweet potato vines exhibits significantly enhanced
OBJECTIVE
In this study, we explored the possibility of construction of a 'universal targeting vector' by Red/ET recombination to inactivate L gene encoding 3-amino-5-hydroxybenzoic acid (AHBA)-oxidoreductase in AHBA biosynthetic gene cluster to facilitate the detection of ansamycins production in
Parkinson's disease (PD) is a progressive neurodegenerative disorder associated with selective loss of dopaminergic neurons in substantia nigra pars compacta. Among the proposed mechanisms of dopaminergic degeneration, oxidative stress is believed to play an important role. On the other hand, L-DOPA
This study investigated the effect of antioxidants on lipid stability of frozen-stored meat products. Buckwheat hull extract was used to enrich fried meatballs made from ground pork. During 180-d storage of meat products, lipid oxidation (peroxide and 2-thiobarbituric acid reactive substances
The allelopathic effect of parthenium (Parthenium hysterophorus L.) leaf residue (dry leaf powder, DLP) on water hyacinth (Eichhornia crassipes Mart Solms.) was studied. The treatment caused wilting starting from the margins of the older leaves and desiccation of above-water plant parts (shoot).
Misfolding, aggregation and deposition of α-synuclein (α-syn) are major pathologic characteristics of Parkinson's disease (PD) and the related synucleinopathy, multiple system atrophy (MSA). The spread of α-syn pathology across brain regions is thought to play a key role in the onset and progression
Caesalpinia decapetala (Roth) Alston (Fabaceae) (CD) is used in folk medicine to prevent colds and treat bronchitis. This plant has antitumor and antioxidant activity. The antioxidant effects of an extract from Caesalpinia decapetala (Fabaceae) were assessed by storage of model food oil-in-water
To clone and study the geldanamycin biosynthetic gene cluster in Streptomyces hygroscopicus 17997, we designed degenerate primers based on the conserved sequence of the ansamycin 3-amino-5-hydroxybenzoic acid (AHBA) synthase gene. A 755-bp polymerase chain reaction product was obtained from S.
A benzoate-degrading archaeal enrichment was developed using sediment samples from Rozel Point at Great Salt Lake, UT. The enrichment degraded benzoate as the sole carbon source at salinity ranging from 2.0 to 5.0 M NaCl with highest rate of degradation observed at 4.0 M. The enrichment was also
