Regiocontrolled Nitration of 4-Quinolones at Ambient Conditions
<div><p></p><p>Regiocontrolled nitration of 4-quinolone, the highly privileged scaffold, has been developed at ambient conditions. The nitro group can selectively be introduced at diverse positions simply by tuning the reactivity of the moiety. Discrimination is being achieved through the selective functionalization of the free N-H group. The functional group has been screened theoretically with the help of Fukui function and local softness calculation. Theoretical predictions are synchronized well with the experimental findings. Finally, this nitration technique allows quick access to the structurally diverse 4-quinolones.</p></div
Performance of the Widely Used Minnesota Density Functionals for the Prediction of Heat of Formations, Ionization Potentials of Some Benchmarked First Row Transition Metal Complexes
We
have computed and investigated the performance of Minnesota
density functionals especially the M05, M06, and M08 suite of complementary
density functionals for the prediction of the heat of formations (HOFs)
and the ionization potentials (IPs) of various benchmark complexes
containing nine different first row transition metals. The eight functionals
of M0X family, namely, the M05, M05-2X, M06-L, M06, M06-2X, M06-HF,
M08-SO, and M08-HX are taken for the computation of the above-mentioned
physical properties of such metal complexes along with popular Los
Alamos National Laboratory 2 double-ζ (LANL2DZ) basis set. Total
54 benchmark systems are taken for HOF calculation, whereas the 47
systems among these benchmark complexes are chosen for the calculation
of IPs because of lack of experimental results on rest of the seven
systems. The computed values of HOFs and IPs are compared with the
experimental results obtained from the literature. The deviation of
these computed values from the actual experimental results is calculated
for each eight different M0X functionals to judge their performances
in evaluating these properties. Finally, a clear relationship between
the exchange correlation energy of eight M0X functionals and their
efficiency are made to predict the different physical properties

Comorbidities in pulmonary tuberculosis cases in Puducherry and Tamil Nadu, India: Opportunities for intervention
<div><p>Background</p><p>We aimed to define characteristics of TB patients in Puducherry and two districts of Tamil Nadu, India and calculate the population attributable fractions (PAF) of TB from malnutrition and alcohol.</p><p>Methods</p><p>New smear-positive TB cases were enrolled into the Regional Prospective Observational Research for Tuberculosis (RePORT India) cohort. Census and National Family Health Survey data were used for comparisons.</p><p>Results</p><p>Data were analyzed for 409 participants enrolled between May 2014-June 2016; 307 (75.1%) were male, 60.2% were malnourished (body mass index [BMI] <18.5 kg/m<sup>2</sup>), and 29.1% severely malnourished (BMI <16). “Hazardous” alcohol use (based on AUDIT-C score) was reported by 155/305 (50.8%) of males. Tuberculosis cases were more likely than the Puducherry population to be malnourished (62.6% v 10.2% males and 71.7% v 11.3% of females; both p<0.001), and male cases were more likely to use alcohol than male non-cases (84.4% v 41%; p < .001). The PAF of malnutrition was 57.4% in males and 61.5% in females; the PAF for alcohol use was 73.8% in males and 1.7% in females.</p><p>Conclusions</p><p>Alcohol use in men and malnutrition are helping drive the TB epidemic in Southern India. Reducing the TB burden in this population will require efforts to mitigate these risk factors.</p></div
