Year-round sustainable biomass production potential of Nannochloris sp. in outdoor raceway pond enabled through strategic photobiological screening.

Microalgae cultivation utilizes the energy of sunlight to reduce carbon dioxide (CO) for producing renewable energy feedstock. The commercial success of the biological fixation of carbon in a consistent manner depends upon the availability of a robust microalgae strain. In the present work, we report the identification of a novel marine Nannochloris sp.

Enhanced Algal Photosynthetic Photon Efficiency by Pulsed Light.

We present experimental results demonstrating that, relative to continuous illumination, an increase of a factor of 3-10 in the photon efficiency of algal photosynthesis is attainable via the judicious application of pulsed light for light intensities of practical interest (e.g., average-to-peak solar irradiance).

Tetramerization at Low pH Licenses DNA Methylation Activity of M.HpyAXI in the Presence of Acid Stress.

Methylation of genomic DNA can influence the transcription profile of an organism and may generate phenotypic diversity for rapid adaptation in a dynamic environment. M.HpyAXI is a Type III DNA methyltransferase present in Helicobacter pylori and is upregulated at low pH.

Functional analysis of an acid adaptive DNA adenine methyltransferase from Helicobacter pylori 26695.

HP0593 DNA-(N(6)-adenine)-methyltransferase (HP0593 MTase) is a member of a Type III restriction-modification system in Helicobacter pylori strain 26695. HP0593 MTase has been cloned, overexpressed and purified heterologously in Escherichia coli. The recognition sequence of the purified MTase was determined as 5'-GCAG-3'and the site of methylation was found to be adenine.

Organic elemental composition in fingernail plates varies between sexes and changes with increasing age in healthy humans.

Background: Keratin, an alpha-helical fibrous protein, is the primary component of human nail plates. No data on age-related changes in healthy subjects are present.

Objective: This study investigated whether keratin amount and composition, as indicated by organic elemental composition of fingernails, varies with aging and between sexes.

Facile one-pot synthesis of thio and selenourea derivatives: a new class of potent urease inhibitors.

A facile, one-pot synthesis of thio and selenourea derivatives from amines using tetrathiomolybdate 1 and tetraselenotungstate 2 as sulfur and selenium transfer reagents, respectively, is reported. The compounds were tested for their activity as urease inhibitors and some of the compounds showed potent activity in the nanomolar range towards jack bean urease.

Ocular involvement in diabetes mellitus.

Diabetes is a worldwide medical problem and is a significant cause of morbidity and mortality. It has considerable impact on both the patient and the society because it typically affects individuals in their most productive years. It is also one of the leading causes of blindness and visual impairment.

Evaluation of Optineurin as a candidate gene in Indian patients with primary open angle glaucoma.

Purpose: To evaluate the role of the optineurin gene (OPTN) in Indian primary open angle glaucoma (POAG) patients from different parts of the country.

Methods: Two hundred patients with POAG and 200 ethnically matched normal controls were recruited from various parts of India for the study. The entire coding region of OPTN along with the intron-exon boundaries were screened by PCR and single strand conformation polymorphism (SSCP) followed by direct sequencing.

Genetics and bioinformatics of primary open angle glaucoma: an Indian perspective.

Glaucoma is the second largest blinding disorder, after cataract, affecting about 67 million people worldwide. In India about 1.5 million people are blind due to glaucoma.

Antimicrobial properties of star anise (Illicium verum Hook f).

Star anise (Illicium verum Hook f) has been shown to possess potent antimicrobial properties. Chemical studies indicate that a major portion of this antimicrobial property is due to anethole present in the dried fruit. Studies with isolated anethole (compared with standard anethole) indicated that it is effective against bacteria, yeast and fungal strains.
