Summary The possibility to eradicate the TB, probably the illness that more damage has caused to the human species, it has been the man's legitimate dream along all its history. This article wants to analyze the complexity of the battle between Mycobacterium tuber- culosis and the human species, trying to carry out a review of all the knowledge reg...

Gap junctions (GJ) are formed by a number of homologous proteins termed connexins. Here expression of connexins Cx26, Cx32 and Cx43, was evaluated by immunofluorescence (IF) in mammary glands from virgin, pregnant and lactating rats. Cx26, Cx32 and Cx43 labeling was detected in epithelial parenchymal cells at all functional stages. Cx26 and Cx32 la...

To describe and quantify the side effects of intravesical BCG therapy (Connaught strain) in different therapeutic protocols. 200 patients were studied; 126 treated according to the standard protocol of our hospital (modality 1 and modality 2: twelve and nine 81 mg instillations, respectively) and 74 patients in the CUETO protocols (90008, 93009, 95...

Leydig cells in vivo and in vitro were shown by immuno-labelling to contain Cx43 but not Cx26 or Cx32. Pairs of Leydig cells dissociated from mouse testis were studied by dual whole cell voltage clamp. Macroscopic and single channel properties of gap junctions between Leydig cells were similar to those in other cells which express Cx43, including i...

Expression of the connexins, Cx26, Cx32 and Cx43, was evaluated by immunofluorescence in mammary gland of virgin, pregnant and lactating rats. In lactating animals punctate labeling of Cx26 and Cx32 was localized to the basal and lateral portions of the alveolar epithelial cells and collecting ductules. Immunoblots confirmed the specificity of the...

A gene for a protein tyrosine phosphatase (PTPase) was isolated from a human fetal brain cDNA library by PCR amplification. Sequence analysis revealed that the PTPase has a single phosphatase catalytic domain located at the C-terminus that includes the highly conserved amino acid domain [I/V]HCXAGXXR[S/T]GX[F/Y] found in all tyrosine phosphatases....

The nuclear factor of activated T cells (NFAT) is a transcription factor complex involved in the activation of cytokines and cell surface molecules associated with coordinating the actions of different cells required for an immune response.

Lactate and pyruvate are transported across cell membranes by monocarboxylate transporters (MCTs). Here, we use the recently cloned cDNA for hamster MCT1 to isolate cDNA and genomic clones for human MCT1. Comparison of the human and hamster amino acid sequences revealed that the proteins are 86% identical. The gene for human MCT1 (gene symbol, SLC1...

In order to analyze the usefulness of bronchoalveolar lavage (BAL) for conventional microbiological diagnosis of tuberculosis (TB) and other mycobacteria, and to assess the need to use it or not as a routine diagnostic technique in these diseases, we studied 30 patients with mycobacteria (26 TB and 4 Mycobacterium avium-intracellulare infections) b...

The diagnosis of nosocomial pneumonia is especially difficult in intubated patients due to the low specificity of their clinico-radiological signs.

Fifty-six chromosome 18-specific yeast artificial chromosomes (YAC) were isolated from a human monochromosomal somatic cell hybrid DNA library. Fluorescence in situ hybridization revealed that the clones were evenly distributed throughout the chromosome. The clones, with an average insert size of 250 kb, cover about 18% of the euchromatic part of c...

A human x Chinese hamster (CH) somatic cell hybrid subclone deficient in HPRT and containing only human chromosome 18 was irradiated with 7000 rad and fused to a thymidine kinase deficient CH cell line. Radiation-rescued hybrid cell lines, selected in HAT medium, were analyzed for human DNA with human interspersed-repeat sequence primers. Size and...

A yeast artificial chromosome (YAC) library was constructed from a somatic cell hybrid line in which the human chromosome content had been reduced by repeated subcloning to one or two copies of chromosome 18. Screening of 4700 primary yeast transformants generated 74 clones containing a YAC with a human DNA insert averaging 190 kb in size. The huma...

The relative efficacy of telescoping plugged catheter (TPC) and bronchoalveolar lavage (BAL) in the diagnosis of pneumonia in mechanically ventilated patients has been compared in 45 subjects suspected of having pneumonia because of the presence of clinical and radiographic criteria. Diagnosis of pneumonia was strongly suggested in 25 of the 45 pat...
