Promising physiological traits associated with nitrogen use efficiency in rice under reduced N application.

Higher grain yield in high-yielding rice varieties is mostly driven by nitrogen (N) fertilizer applied in abundant amounts leading to increased production cost and environmental pollution. This has fueled the studies on nitrogen use efficiency (NUE) to decrease the N fertilizer application in rice to the possible extent. NUE is a complex physiological trait controlled by multiple genes, but yet to be completely deciphered in rice.

Takayasu arteritis, an atypical presentation as chronic kidney disease.

Takayasu arteritis, also known as "pulseless disease" usually affects major vessels like aorta and its branches, pulmonary arteries, and renal arteries. Hypertension is the common presentation. Chronic kidney disease involvement is less common.

Speciation study involving mononuclear binary transition metal (Co, Ni and Cu) complexes of L-methionine in non-ionic micellar medium.

The present work aims to evaluate the binding capacities of binary complexes of L-Methionine with transition metal ions Co, Ni and Cu in Triton X 100-water mixtures, a non-ionic micellar media of different compositions (0.0-2.5% (v/v)), investigated under the experimental conditions of 0.

Ophthalmic manifestations in the COVID-19 clinical spectrum.

Purpose: The aim of this study was to determine the frequency and various types of ophthalmic manifestation of patients with COVID-19.

Methods: This is a prospective observational study conducted on patients with SARS-Co-V-2 infection, at a dedicated tertiary COVID-19 hospital in South India from April 1 to July 31, 2020. At the time of their admission to the COVID hospital, demographic data such as name, age, sex was recorded.

Fusion of cellulose binding domain to the catalytic domain improves the activity and conformational stability of chitinase in Bacilluslicheniformis DSM13.

Chitinase from Bacilluslicheniformis DSM13 consists of an N-terminal catalytic domain (GH) and a C-terminal chitin binding domain (ChBD). A deletion mutant BliGH and a hybrid chitinase BliGH-CeBD were developed using polymerase chain reaction (PCR) to study the role of substrate-binding domain. Both recombinant chitinases retained their ability to bind to glycol-chitin (GC).

The effect of povidone-iodine and chlorhexidine mouth rinses on plaque Streptococcus mutans count in 6- to 12-year-old school children: an in vivo study.

Objectives: Treating a carious tooth in children with high caries experience by providing a restoration does not cure the disease. If the unfavorable oral environment that caused the cavity persists so will the disease and more restorations will be required in future. Treating the oral infection by reducing the number of cariogenic microorganisms and establishing a favorable oral environment to promote predominantly remineralization of tooth structure over time will stop the caries process.

Role of arginase in sciatectomized muscle.

Substrate kinetics of arginase were investigated in normal and sciatectomized gastrocnemius muscle of frog. Sciatectomized muscle arginase showed 47% elevation in V while Km showed no change. Sciatectomic activation of muscle arginase accounted for the stepped up urea levels which may be of significant use in combating ammonia toxicity and maintaining chemohomeostasis.
