Novel A-π-D-A organic dyes for better photovoltaic performance.

In this article, we report two indole-based metal-free organic dyes In-T-2C (3-(5-(3-((2-carboxy-2-cyanovinyl)-1-pentyl-1-indol-5-yl)thiophen-2-yl)-2-isocyanoacrylic acid) and In-B-C (2-cyano-3-(5-(4-cyanophenyl)-1-pentyl-1-indol-3-yl)acrylic acid) with A-π-D-A architecture. The molecular structures of metal-free indole-based A-π-D-A organic dyes were elucidated using FT-IR, NMR, HRMS and single-crystal X-ray diffraction techniques. The present investigation examined the features of the synthesized dyes employing photophysical attributes, electrochemical traits and theoretical studies were executed to acquire a detailed comprehension of the geometry, electronic structure and absorption spectra of the synthesized dyes using density functional theory (DFT) and time-dependent density functional theory (TD-DFT).

Study on blood glucose concentration in patients with diabetes undergoing dental extraction under local anesthesia with and without adrenaline.

Background: The aim of this study was to compare the effect of adrenaline on blood glucose concentration in patients with diabetes undergoing tooth extraction under local anesthesia and also to find out whether blood glucose concentration differs if local anesthetics are injected in clinical doses with and without adrenaline.

Methods: Patients included had a tooth in need of extraction, were in the 25-55 years age group, had a random blood sugar level ≤140 mg/dL and were on oral antidiabetic drugs. The 25 patients in Group A were injected with 2 mL of lignocaine hydrochloride without adrenaline (xylocaine 2%) and the other 25 patients (Group B) were injected with 2 mL lignocaine hydrochloride along with adrenaline 1:80,000.

Study of short term memory status in adult bipolar disorder patients in south Indian population.

The present study was undertaken to establish short term memory status in bipolar disorder cases as compared with normal age and sex matched control group in Bijapur (Karnataka). Results showed that a significant decrease in short term memory status in bipolar disorder cases as compared to their control group .Loss of attention, decreased processing speed and executive function patterns may be the probable causes of such observations.
