Selective synthesis of fluorescent metal nanoclusters over metal nanoparticles.

Metal nanoparticles and nanoclusters are pivotal in nanomaterial science, each offering unique properties for diverse applications. Nanoclusters, typically smaller than 2 nm, exhibit distinct optical and electronic characteristics due to quantum confinement, resulting in fluorescence emission. In contrast, metal nanoparticles, sized between 2 and 100 nm, exhibit absorption spectra.

A Cross-Sectional Study of Clinical Spectrum and Outcome of Pure Midbrain Strokes.

Background: Pure mesencephalic infarcts are uncommon, the main clinical manifestations being oculomotor signs and ataxia.

Objectives: Primary objective was to determine the incidence of pure midbrain strokes. We also evaluated the clinical spectrum, syndromes, arterial territories involved, risk factors, and outcome at 3 months.

Characteristics of Bachaur bull semen.

The Bachaur is a mediumized draft purpose breed which has been recognized by ICAR-National Bureau of Animal Genetic Resources (NBAGR) Karnal, India, and presently is on the verge of extinction. Since there are no data regarding the seminal parameters of this breed, this work was performed to evaluate seminal parameters of freshly ejaculated semen. A total of three healthy breeding Bachaur bulls aged 2.
