Maternal Height as an Independent Risk Factor for Neonatal Size among Adolescent Bengalees in Kolkata, India
No full textBACKGROUND: Low Birth Weight is a major public health problem in developing countries. The causes of LBW are multifactorial including complication during pregnancy, genetic, environmental, social-cultural, demographic and nutritional variables. Comparison of anthropometric risk factors for neonatal size of adolescent mothers are lacking from West Bengal. Therefore, this study was undertaken to identify maternal anthropometric characteristics, which most strongly influence neonate weight and length among Bengalee mothers.
METHODS: A hospital based cross-sectional study was undertaken during 2004 in a Government general hospital in South Kolkata, India. A total of 76 adolescent (ag

No full textOrganocatalytic direct asymmetric anti-aldol reaction was developed in aqueous medium using a BINOL-derived diamine/protic acid bifunctional catalyst. The catalytic protocol could offer the opportunity to access anti-aldol products with high level of enantioselectivities with moderate diastereoselectivities
Trimethylsilyl cyanide addition to aldimines and its application in the synthesis of (S)-phenylglycine methyl ester
No full textThe addition of TMSCN to a variety of arylaldimines (Strecker reaction) in the presence of LiClO4 or BF3·Et2O in acetonitrile has been studied. The reaction provided the addition products in very high yields. The method has been successfully utilized for the synthesis of (S)-phenylglycine methyl ester
Enantioselective one-pot three-component synthesis of propargylamines catalyzed by copper(I)–pyridine bis-(oxazoline) complexes
No full textA one-pot three-component coupling of aldehydes and amines in presence of terminal alkynes has been efficiently catalyzed by copper (I) complex of i-Pr-pybox-diPh 2b or s-Bu-pybox-diPh 2c. The process is simple and allows the synthesis of various propargylamines in good to excellent enantioselectivities (up to 99% ee) and in higher yields. The nature of the substituents attached to imines plays a vital role on the enantioselectivities obtained. The presence of gem-diphenyl group at C-5 position and secondary alkyl substituents at the C-4 chiral center of the oxazoline rings of the chiral ligands was found to be crucial for higher enantioselectivities. A transition state model involving p-p stacking is also proposed for the stereochemical outcome
Asymmetric Syntheses of Medicinally Important Isoindolinones (<i>S</i>)‑PD 172938, (<i>R</i>)‑JM 1232, and Related Structures
No full textA unified approach
for the asymmetric syntheses of medicinally
important isoindolinones (S)-PD 172938 and (R)-JM 1232 has been accomplished via a Cu(I)-PYBOX-diPh
catalyzed highly enantioselective (up to 99% ee) alkynylation/lactamization
sequence in a one-pot fashion. The overall sequence involves one C–C
and two C–N bond forming events in one pot starting from inexpensive
starting material in ambient reaction conditions
Critical nutritional stress among adult tribal populations of West Bengal and Orissa, India.
No full textThis paper deals with cross-sectional studies carried out during the period 2004-2007. It is based on eight data sets of tribals of Paschim Medinipur and Bankura Districts of West Bengal and Keonjhar District of Orissa. The tribes include Bhumijs, Kora Mudis, Lodhas, Santals, Bathudis and Savars. Height and weight were measured following standard techniques. The body mass index (BMI) was computed following standard equation. Nutritional status (chronic energy deficiency, CED) was evaluated using internationally accepted cut-off values of BMI. We followed the World Health Organization's classification (1995) of the public health problem of low BMI, based on adult populations worldwide. Our results show that, in general, among the tribes studied:
i)Both sexes had very low levels of BMI
ii)There existed high rates of CED indicating a critical nutritional condition 
iii)Women experienced greater nutritional stress
iv)The nutritional situation is similar in both West Bengal as well as Orissa.

The hydration and solute—solvent interaction parameters of five polyethylene glycols PEG 200, 300, 400, 600 and 1000, have been reported. The hydration has been unambiguously evaluated using conductance and viscosity methods. A comparison of the important literature cited hydrations of EO group with the results of this study has been made. The viscosity B and C coefficients have been obtained from a quadratic fitting of relative viscosity with mol dm concentration of the PEG. The B coefficient has been analysed in the light of molecular size, solvation and water—structure modification. The solute—solute interaction parameter C has been observed to be significant for PEG 600 and 1000. The results are more consistent than that reported by Bahri and Guveli given in reference seventeen
Double burden of malnutrition among urban Bengalee adolescent boys in Midnapore, West Bengal, India
No full textMalnutrition is an important public health problem worldwide. Therefore a study was undertaken to assess the prevalence of adolescent thinness, overweight and obesity in Midnapore town, West Bengal, India. A total of 974 adolescent boys aged 10-18 years were selected following multistage cluster sampling method from three higher secondary schools. Data was collected using pretested questionnaire following standard technique. Presence of thinness was evaluated using the cut-off values of international survey as suggested by Cole et al (2007). While overweight and obesity was determine by using international cut-off values develop by Cole et al (2000) based on international surveys as recommended by IOTF. Overall the prevalence of thinness, overweight and obesity were 20.8%, 14.9% and 3.8%, respectively. This study developed age specific smooth BMI percentile values using LMS method. Moreover, the study also developed BMI cut-off values to define thinness, overweight and obesity. In conclusion, the present analyses indicated that the prevalence of adolescent undernutrition is still a major problem. In addition, there was also an emerging trend for overweight/obesity, thereby indicating a double burden of malnutrition as observed in other developing countries
