In patients with HIV infection the diagnosis of PCP is relatively simple when patients present late, with advanced pneumonia. The diagnosis becomes more difficult when patients present with minimal symptoms, are receiving specific prophylactic therapy or have had previous AIDS-related pulmonary diseases. A number of non-invasive tests, such as Gallium scanning, exercise-induced hypoxaemia, DTPA scanning and lung function testing have been developed to improve on the diagnostic value of clinical examination and the chest X-ray. Although each has its own particular advantages and disadvantages, the most efficient means of diagnosing PCP, in patients presenting with respiratory symptoms, is to use these investigations as part of a diagnostic algorithm, thereby maximizing resources and defining relative risks for different types of patients.

We examined the effects of travel on the health of a group of HIV-infected adults (n = 89) cared for in a public hospital HIV clinic. In a period of 2 years, 45% travelled to a median of 3 US destinations for at least one week and 20% travelled to at least one international destination for a mean duration of 20 days. At the time of completion of the survey, the majority of these patients were severely immunosuppressed (median CD4+ count, 120/mm3). A physician was consulted concerning travel before 53% of the trips, but only one person consulted a travel medicine expert. All but one patient (98%) who was receiving medical therapy carried sufficient supplies of medication; 95% estimated their compliance with medication at 75% or better. None of the travellers to developing countries received gamma globulin, but one received yellow fever vaccine. Fifteen travellers (43%) became ill either during their trip or immediately thereafter; 3 required hospitalization. While most illnesses were not severe, 4 patients developed potentially life-threatening infections including coccidioidomycosis, cryptococcosis, PCP, and bacterial pneumonia. This survey provides information by which the clinician can anticipate the health care needs of HIV-infected patients who travel. HIV-infected patients should be more aware of the necessity for medical counsel prior to travel.

In Brassica, two self-incompatibility genes, encoding SLG (S locus glycoprotein) and SRK (S-receptor kinase), are located at the S locus and expressed in the stigma. Recent molecular analysis has revealed that the S locus is highly polymorphic and contains several genes, i.e., SLG, SRK, the as-yet-unidentified pollen S gene(s), and other linked genes. In the present study, we searched for expressed sequences in a 76-kb SLG/SRK region of the S(9) haplotype of Brassica campestris (syn. rapa) and identified 10 genes in addition to the four previously identified (SLG(9), SRK(9), SAE1, and SLL2) in this haplotype. This gene density (1 gene/5.4 kb) suggests that the S locus is embedded in a gene-rich region of the genome. The average G + C content in this region is 32.6%. An En/Spm-type transposon-like element was found downstream of SLG(9). Among the genes we identified that had not previously been found to be linked to the S locus were genes encoding a small cysteine-rich protein, a J-domain protein, and an antisilencing protein (ASF1) homologue. The small cysteine-rich protein was similar to a pollen coat protein, named PCP-A1, which had previously been shown to bind SLG.

Many flowering plants possess self-incompatibility (SI) systems that prevent inbreeding. In Brassica, SI is controlled by a single polymorphic locus, the S locus. Two highly polymorphic S locus genes, SLG (S locus glycoprotein) and SRK (S receptor kinase), have been identified, both of which are expressed predominantly in the stigmatic papillar cell. We have shown recently that SRK is the determinant of the S haplotype specificity of the stigma. SRK is thought to serve as a receptor for a pollen ligand, which presumably is encoded by another polymorphic gene at the S locus. We previously have identified an S locus gene, SP11 (S locus protein 11), of the S(9) haplotype of Brassica campestris and proposed that it potentially encodes the pollen ligand. SP11 is a novel member of the PCP (pollen coat protein) family of proteins, some members of which have been shown to interact with SLG. In this work, we identified the SP11 gene from three additional S haplotypes and further characterized the gene. We found that (i) SP11 showed an S haplotype-specific sequence polymorphism; (ii) SP11 was located in the immediate flanking region of the SRK gene of the four S haplotypes examined; (iii) SP11 was expressed in the tapetum of the anther, a site consistent with sporophytic control of Brassica SI; and (iv) recombinant SP11 of the S(9) haplotype applied to papillar cells of S(9) stigmas, but not of S(8) stigmas, elicited SI response, resulting in inhibition of hydration of cross-pollen. All these results taken together strongly suggest that SP11 is the pollen S determinant in SI.

Despite the advances in cancer treatment and the progresses in tumor biological, ovarian cancer remains a bad situation. In current study, we found a novel extracellular matrix protein, ITGBL1, which is highly expressed in ovarian cancer tissues by immunohistochemistry examination. The expression pattern of ITGBL1 in malignant tissues inspired us to investigate its role in ovarian cancer progression. Both loss- and gain-function assays revealed that ITGBL1 could promote ovarian cancer cell migration and adhesion. As it's a secreted protein, we further used recombinant ITGBL1 protein treated cancer cells and found that ITGBL1 promotes cell migration and adhesion in a concentration dependent manner. Furthermore, we found that ITGBL1 not only influences the activity of Wnt/PCP signaling but also affects FAK/src pathway in vitro. Taken together, our results suggest that highly expressed ITGBL1 could promotes cancer cell migration and adhesion in ovarian cancer and as a secreted protein, ITGBL1 might be a novel biomarker for ovarian cancer diagnosis.
