Intervalence plasmons in boron-doped diamond.

Doped semiconductors can exhibit metallic-like properties ranging from superconductivity to tunable localized surface plasmon resonances. Diamond is a wide-bandgap semiconductor that is rendered electronically active by incorporating a hole dopant, boron. While the effects of boron doping on the electronic band structure of diamond are well-studied, any link between charge carriers and plasmons has never been shown.

ICAM-1 K469E gene polymorphism, genotype-phenotype correlation, and retinopathy in Type 2 diabetes mellitus patients.

Context: The role of genetic factors in the development of diabetic retinopathy is evident from the fact that only 50% of patients with the non-proliferative type of diabetic retinopathy progress to proliferative diabetic retinopathy. Though the K469E polymorphism of the ICAM-1 (Intercellular Adhesion Molecule-1) gene is known to increase the risk of developing Diabetic Retinopathy (DR) among Type 2 diabetic patients, its role in the development of severe DR has not been extensively studied.

Aim: Hence, we aimed to determine the risk due to association of K469E polymorphism of ICAM-1 gene and sight threatening diabetic retinopathy.

A Prospective Nonrandomized Comparison of Wet Needling Versus Prolotherapy in Myofascial Pain.

Objective: The objective was to analyze the difference between prolotherapy and wet needling (WN) for myofascial trigger points (MTrPs) for the Visual Analog Scale (VAS), Oswestry Disability Index (ODI), Clinical Global Impression (CGI), and MTrP count.

Methods: Patients with myofascial pain for 1.5 years were included based on convenience sampling after a pilot study for sample size calculation.
