Unraveling correlative roles of dopamine transporter (DAT) and Parkin in Parkinson's disease (PD) - A road to discovery?

Parkinson's disease (PD) is a neurodegenerative disorder accompanied by depletion of dopamine(DA) and loss of dopaminergic (DAergic) neurons in the brain that is believed to be responsible for the motor and non-motor symptoms of PD. Dopamine Transporter (DAT) is essential for reuptake of DA into the presynaptic terminal, thereby controlling the availability and spatial activity of released DA. Parkin interacts with proteins involved in the endosomal pathway, suggesting that presynaptic Parkin could regulate the expression of DAT in the plasma membrane.

Does epigenetics have a role in age related macular degeneration and diabetic retinopathy?

Epigenetic mechanisms play an important part in the regulation of gene expression and these alterations may induce long-term changes in gene function and metabolism. They have received extensive attention in bridging the gap between environmental exposures and disease development via their influence on gene expression. DNA methylation is the earliest discovered epigenetic alteration.

Targeting phosphoinositide-3-kinase pathway in biliary tract cancers: A remedial route?

Biliary tract cancers (BTC) are aggressive tumours with a low survival rate. At the advent of the genomic era, various genetic mutations in cell signalling pathways have been incriminated in carcinogenesis. Genomic analysis studies have connected main components of the phosphoinositide-3-kinase (PI3K) signalling pathway to BTC.

Electrochemical Analysis of the Carbon-Encapsulated Lithium Iron Phosphate Nanochains and Their High-Temperature Conductivity Profiles.

Carbon-encapsulated LiFePO (LFP) nanochains were prepared as a cathode material for lithium batteries by sol-gel method using citric acid as the carbon source. The prepared LFP/C material is characterized by structural, morphological, and electrochemical characterization. LFP/C shows an orthorhombic olivine structure with "" space group having an average particle size of 50 nm.

Ampullary carcinoma-A genetic perspective.

Ampulla of vater carcinoma (AVC) is a rare gastrointestinal tumour that is associated with a high mortality rate and it's often diagnosed at later stages due to lack of clinical symptoms. Early diagnosis of this condition is essential to effectively treat patients for better prognosis. A significant amount of advancement has been made in understanding the molecular nature of cancer in the past decade.

Blue light emitting YO:Tm nanophosphors with tunable morphology obtained by bio-surfactant assisted sonochemical route.

Modified sonochemical route was used to prepare YO:Tm (1-11mol%) nanophosphor using Mimosa pudica (M.P.) leaves extract as bio-surfactant.

In silico analysis of aqueous root extract of Rotula aquatica Lour for docking analysis of the compound 3-O-acetyl-11-keto-β-boswellic acid contents.

Molecular docking is a bioinformatics tool used to study and analyse ligand receptor interactions. This helps in identifying the receptors (molecular targets) for different ligands. Using these technologies, compound isolation and drug discovery from herbals is achieved.

Free radical scavenging activity and comparative metabolic profiling of in vitro cultured and field grown Withania somnifera roots.

Free radical scavenging activity (FRSA), total phenolic content (TPC), and total flavonoid content (TFC) of in vitro cultured and field grown Withania somnifera (Ashwagandha) roots were investigated. Withanolides analysis and comprehensive metabolic profiling between 100% methanol extracts of in vitro and field grown root tissues was performed using high performance thin layer chromatography (HPTLC) and gas chromatography-mass spectrometry (GC-MS), respectively. Significantly higher levels of FRSA, TPC, and TFC were observed in in-vitro cultured roots compared with field grown samples.

Identification and determination of flavonoids, carotenoids and chlorophyll concentration in Cynodon dactylon (L.) by HPLC analysis.

Cynodon dactylon (L.) is a potent medicinal plant in the traditional and current Indian medicinal systems. The objective of this research was to find out the levels of flavonoids, carotenoids and chlorophyll b in C.

Sphingopyxis panaciterrulae sp. nov., isolated from soil of a ginseng field.

A Gram-negative, rod-shaped, motile bacterium was isolated from the soil of a ginseng field in Daejeon, South Korea, and characterized in order to determine its taxonomic position. Phylogenetic analysis based on 16S rRNA gene sequence analysis revealed that strain DCY34(T) belonged to the family Sphingomonadaceae, and the highest degree of sequence similarity was found with Sphingopyxis witflariensis W-50(T) (97.1 %), Sphingopyxis ginsengisoli Gsoil 250(T) (97.

Generation and analysis of expressed sequence tags from leaf and root of Withania somnifera (Ashwgandha).

The first transcriptomes, expressed sequence tags (ESTs) in a leaf and root from Withania somnifera plant referenced in this report are the first of its kind. A cDNA library was constructed from samples of the 2-months-old, in vitro cultured leaves and roots, which generated 1,047 leaf cDNA and 1,034 root cDNA clones representing 48.5% and 61.

Role of medicinal plant Salacia Reticulata in the management of Type II Diabetic Subjects.

Diabetes mellitus is one of the leading causes of death and ranks third among the chronic diseases. Recent studies have shown that up to 10 % of India's urban population and 2 % of the rural population above the age of 15 years have diabetes and WHO had declared India as the diabetic capital of the world. India has wealth of medicinalplants, and these plants have credited to the development of therapeutic agents for various ailments and diseases.

Supplementing iron bioavailability enhanced mung bean.

Iron deficiency anaemia is a major public health problem. The high incidence is either due to insufficient intake of iron or poor bio availability. Enhancing the bio availability is as important as increasing the intake.

Antibacterial activity of Aegle marmelos against leaf, bark and fruit extracts.

The antibacterial activity of the methanol, chloroform and aqueous extracts from the leaves, bark and fruit of A. marmelos was studied using disc diffusion method against Bacillus subtilis, Staphylococcus aureus (Gram Positive), Klebsiella pneumoniae, Proteus mirabilis, Escherichia coli, Salmonella paratyphi A and Salmonella paratyphi B (Gram Negative).
