Information flow, expectations and job search: rural-to-urban migration process in India.

"Probabilistic migration models assume that search for urban jobs is entirely an urban-based activity and that employment in free-entry activities is a transitional phase during which migrants are actively searching for formal sector employment. This paper tests the empirical validity of these assumptions using data, collected by the author in a sample survey in Delhi [India] in 1975-76, on 1,400 migrants from rural areas." Evidence is presented "that the migration process postulated in probabilistic models is not realistic in the case of Delhi. Over one-half of the sample had moved to Delhi after lining up specific jobs; a sizeable proportion expected to enter on arrival activities generally considered to be characterized by freedom of entry; and the majority of entrants into free-activities did not search for alternative employment and were engaged in the same activities at the time of the survey."

Unique and shared IgE epitopes of Hev b 1 and Hev b 3 in latex allergy.

Of the several latex proteins cloned and expressed, the rubber elongation factor, Hev b 1, and the closely related Hev b 3, represent two major allergens associated with latex allergy. Although both allergens demonstrated IgE binding with sera from latex allergic patients, it was not known whether these two molecules shared any epitopes. Hence, in the present study using health care workers (HCW) and spina bifida (SB) patients with latex allergy, we investigated the IgE binding epitopes in Hev b 1 and Hev b 3. Recombinant Hev b 1 and Hev b 3 were expressed in a prokaryotic expression system, while overlapping decapeptides of Hev b 1 and Hev b 3 were synthesized on derivatized cellulose membrane. Eight IgE binding epitopes for Hev b 1 and eleven for Hev b 3 were identified using sera from latex allergic patients with SB. On further analysis of synthetic peptides encompassing these epitopes, similar IgE antibody reactivity was demonstrated with three Hev b 1 epitopes b1E3, b1E5, b1E6 and two Hev b 3 epitopes; b3E10 and b3E 11. For Hev b 1, a unique IgE binding epitope was identified in the region of amino acid residues 16-25. In competitive ELISA, peptides bIE2 and bIE4 together inhibited 58% of IgE binding of Hev b 1, while b3E5 showed 22% inhibition in the IgE binding of Hev b 3. The results of the present study suggest that the understanding of linear and conformational IgE epitopes in the major latex allergens may provide better insight into the structure-function relationship of the allergens, and may lead to the development of better patient care and management strategies in latex allergy.

Percutaneous transcholecystic approach to the rendezvous procedure when transhepatic access fails.

PURPOSE: Extrahepatic biliary obstruction can be managed endoscopically or percutaneously. When endoscopic therapy fails, percutaneous drainage with or without endoscopic assistance may be performed. However, transhepatic drainage may itself be unsuccessful. In such patients, a transcholecystic approach combined with endoscopic therapy was used to achieve biliary drainage. MATERIALS AND METHODS: After attempts at transhepatic biliary drainage failed, a percutaneous cholecystostomy was performed in four patients, with subsequent cannulation of the common bile duct, endoprosthesis insertion, or papillotomy. RESULTS: The success rate was 100%, with no major complication or procedure-related mortality. Slight bleeding from a sphincterotomy was the only minor complication. CONCLUSION: When percutaneous transhepatic access to the bile duct fails, the transcholecystic route can be safely used with care to successfully achieve biliary drainage.
