Efficient combination of promoter and catalyst for chromic acid oxidation of propan-2-ol to acetone in aqueous acid media at room temperature

Oxidation of propan-2-ol to acetone was carried out in aqueous media at room temperature. The effect of promoter (PA, bpy, phen), micellar catalyst (SDS, CPC, TX-100) and their combination has been studied. The reactions were performed under the condition [Propan-2-ol]T≫[Cr(VI)]T at 30°C. Then kobs and half life of all the reaction were determined to identify which promoter and which combination are the most effective for this oxidation. Among the promoters phen accelerates the reaction most in aqueous media. In absence of promoters anionic surfactant SDS increases the rate more effectively than neutral surfactant TX-100. CPC retards the rate in comparison to aqueous media. The rate of the oxidation is highest in presence of the combination of bpy and SDS.

Socioeconomic consequences of HIV/AIDS in the family system

INTRODUCTION

HIV/AIDS can lead to poverty affecting particularly women and young people and can halt or reverse socioeconomic development of a country.

OBJECTIVE

The objective of this study was to assess the socioeconomic consequences of HIV/AIDS within the family.

MATERIALS AND METHODS

A cross-sectional descriptive study was carried out among patients admitted in in-patient department and those attending integrated counseling and testing centre (ICTC) of School of Tropical Medicine, Kolkata. Data were gathered by interviewing the patients by using a predesigned questionnaire.

RESULTS

For prolonged duration and severity of disease, higher proportion of indoor patients reported loss of job, decreased family income, increased expenditure for care seeking, and faced greater economic consequences, reflected by selling assets. Loss of job was mainly due to illness (86.8%), disclosure of sero-status (13.2%), and predominantly among skilled workers. Assets were sold mainly to meet the cost of own illness for indoor patients, but more to meet the expenditure for husband's illness, in the case of ICTC patients. High school dropout seen in both groups was mainly due to economic reasons. HIV/AIDS status was known to other members of family for 84.8% of indoor patients out of which 15.4% experienced rejection by family members. Out of 72 ever married women indoor patients whose in-laws were aware of their HIV/AIDS status, 41.7%, 40.9%, and 33.33% reportedly were blamed for spouse's illness, and had strained relation with in-laws and spouse, respectively.

CONCLUSION

Intensive behavior change communication and provision of care and support are required to curb AIDS-related stigma, discrimination, and to maintain physical, mental, and social wellbeing of people living with HIV/AIDS.

Micellar Catalysis of the 1,10-Phenanthroline-Promoted Chromic Acid Oxidation of Propan-2-ol in Aqueous Media

In aqueous media 1,10-phenanthroline (phen) promoted chromic acid oxidation of propan-2-ol produces propan-2-one (acetone). Acetone is separated from the mixture by fractional distillation. The effect of an anionic surfactant (SDS) and a neutral surfactant (TX-100) on the unpromoted and phen-promoted path have been studied. The catalytic effects of micelles have been explained by considering the preferential partitioning of reactants between the micellar and aqueous phases. The reaction becomes much faster when phen and TX-100 are combined together.

A Novel LMNA Mutation Causes Altered Nuclear Morphology and Symptoms of Familial Partial Lipodystrophy (Dunnigan Variety) with Progeroid Features

Dunnigan-type partial lipodystrophy (familial partial lipodystrophy, Dunnigan variety, FPLD2) can be caused by LMNA mutations. We identified a novel heterozygous LMNA mutation, P485R, in a patient referred to the International Registry of Werner Syndrome because of features consistent with that of progeroid disorder but who was wild type at the WRN locus. The novel mutation is located 2 amino acids away from the canonical FPLD mutations in exon 8 of the LMNA gene. Immunocytochemical analysis revealed abnormal nuclear morphology characteristic of laminopathies within primary fibroblast cultures, but not in a lymphoblastoid cell line, in keeping with previous observations. Our findings indicate that FPLD2 should be considered in the differential diagnosis of the Werner syndrome.
