Summary. Genetic polymorphisms in the tumour necrosis factor (TNF) locus influence the outcome of non‐Hodgkin's lymphoma (NHL). We investigated whether these polymorphisms might contribute to the clinical course of childhood acute lymphoblastic leukaemia (ALL). Genomic DNA from 214 childhood ALL patients was analysed. Patients with a high‐risk haplotype were older than patients with low‐risk haplotype ( P = 0·024). No statistically significant associations were found between TNF haplotype and sex, WBC ...

Hypermethylation of CpG islands within the promoter region is one of the mechanisms by which genes are inactivated and may be one of the reason for silencing of cell cycle control or DNA-mismatch repair genes in myelodysplastic syndrome (MDS). Since the function of cell cycle control genes including the cyclin-dependent kinase inhibitors known as p15INK4b and p16INK4a, as well as p14ARF which blocks MDM-2 (an inhibitor of p53), the retinoblastoma (RB1) protein and the mismatch repair gene MGMT is critical ...

Adult T-cell leukaemia/lymphoma (ATL) is associated with the monoclonal integration of human T-lymphotropic virus type I (HTLV-I) proviral DNA into tumour cells, but the incidence of ATL is low (2–5%) among HTLV-I carriers; and those who develop the disease usually have a 40- to 60-year latency period from the time of infection to progression to ATL. These phenomena suggest that additional mechanisms are involved in the progress of the disease, such as inactivation of tumour suppressor genes, or activation ...

Rationale: The long-term effects of using a high-flow nasal cannula for chronic hypercapnic respiratory failure caused by chronic obstructive pulmonary disease remain unclear. Objectives: To assess whether long-term high-flow nasal cannula use reduces the number of exacerbations and improves other physiological parameters in patients with chronic hypercapnic respiratory failure caused by chronic obstructive pulmonary disease. Methods: We enrolled 104 participants (aged ⩾40 yr) with daytime hypercapnia ( ...

Background: Afatinib is an effective first-line treatment for epidermal growth factor receptor (EGFR) mutation-positive advanced non-small cell lung cancer (NSCLC). However, few reports have addressed the influence of cerebrospinal fluid (CSF) penetration rate on the efficacy of afatinib in patients with central nervous system metastases. Therefore, we conducted a prospective multicenter trial to evaluate the CSF penetration rate and efficacy of afatinib in patients with EGFR mutation-positive NSCLC ...

Although maintaining anesthesia for myasthenia gravis (MG) with minimal muscle relaxants (MR) is common, the success rate of anesthetic management for MG without MR is not clear. We therefore retrospectively examined the success rate of anesthetic management for MG without MR among 66 consecutive cases of thymectomy for MG performed at our hospital between January 2004 and April 2010, before approval of using sugammadex. A total of 60 patients (90.9 %) were treated without MR (N group). Among the 60 cases, ...

Divergent selection and adaptive divergence can increase phenotypic diversification amongst populations and lineages. Yet adaptive divergence between different environments, habitats or niches does not occur in all lineages. For example, the colonization of freshwater environments by ancestral marine species has triggered adaptive radiation and phenotypic diversification in some taxa but not in others. Studying closely related lineages differing in their ability to diversify is an excellent means ...

Serum markers, including Krebs von den Lungen (KL-6), surfactant protein (SP)-D, SP-A and carcinoembryonic antigen (CEA), are reported to reflect autoimmune pulmonary alveolar proteinosis (APAP) disease severity. We evaluated serum CYFRA21-1 levels as a marker of APAP.In addition to KL-6, SP-D and CEA, we prospectively measured serum CYFRA 21-1 levels in 48 patients with APAP, consecutively diagnosed between 2002 and 2010. Diagnostic usefulness of CYFRA 21-1 was determined from 68 patients with interstitial ...

Although similar patterns of phenotypic diversification are often observed in phylogenetically independent lineages, differences in the magnitude and direction of phenotypic divergence have been also observed among independent lineages, even when exposed to the same ecological gradients. The stickleback family is a good model with which to explore the ecological and genetic basis of parallel and nonparallel patterns of phenotypic evolution, because there are a variety of populations and species ...

Summary Understanding how habitat fragmentation affects population processes (e.g. dispersal) at different spatial scales is of critical importance to conservation. We assessed the effects of habitat fragmentation on dispersal and regional and fine‐scale population structure in a currently widespread and common cooperatively breeding bird species found across south‐eastern A ustralia, the superb fairy‐wren M alurus cyaneus . Despite its relative abundance and classification as an urban tolerant species, ...

Understanding the processes leading to population declines in fragmented landscapes is essential for successful conservation management. However, isolating the influence of disparate processes, and dispersal in particular, is challenging. The Grey Shrike-thrush, Colluricincla harmonica, is a sedentary woodland-dependent songbird, with learned vocalizations whose incidence in suitable habitat patches falls disproportionally with decline in tree cover in the landscape. Although it has been suggested ...

Habitat loss, fragmentation and degradation are drivers of major declines in biodiversity and species extinctions. The actual causes of species population declines following habitat change are more difficult to discern and there is typically high covariation among the measures used to infer the causes of decline. The causes of decline may act directly on individual fitness and survival, or through disruption of population processes. We examined the relationships among configuration, extent and status ...

Gefitinib is an effective treatment for patients with non-small cell lung cancer who harbor activating epidermal growth factor receptor (EGFR) mutations. However, no optimal strategy has been established for these patients after gefitinib fails. The aim of this retrospective study was to assess the survival benefit of continued gefitinib treatment in these cases.We analyzed gefitinib responders with activating EGFR mutations who developed progressive disease (PD) during the course of therapy. Prognostic ...

One of the main techniques for recognizing individuals in avian field research is marking birds with plastic and metal leg rings. However, in some species individuals may react negatively to rings, causing leg injuries and, in extreme cases, the loss of a foot or limb. Here, we report problems that arise from ringing and illustrate solutions based on field data from Brown Thornbills (Acanthiza pusilla) (2 populations), Siberian Jays (Perisoreus infaustus) and Purple-crowned Fairy-wrens (Malurus coronatus). ...

We have evaluated the distribution of fatty infiltration in the liver for determination of a suitable biopsy site for diagnosis of tamoxifen-induced non-alcoholic steatohepatitis (NASH) in patients with breast cancer. Thirty-eight consecutive breast cancer patients undergoing tamoxifen treatment were analyzed by CT to identify hepatic steatosis (HS) via calculation of the liver/spleen CT ratio in Couinaud's 8 areas. We defined hepatic fatty infiltration as a liver/spleen ratio of less than 0.9. The ...

Central to many cancers is the aberrant expression of genes that regulate the cell cycle including the cyclin-dependent kinase inhibitors known as p15INK4b and p16INK4a, p14ARF and the retinoblastoma (RB) protein. We performed a detailed analysis of the methylation status of these genes by methylation specific polymerase chain reaction (MSP) in tumor cells of 35 adult T-cell leukemia/lymphoma (ATL) patients. We found in nine of 35 cases (26%) at least one gene methylated. The frequency of p15INK4b methylation ...

It has been stated, but not adequately assessed, that pulmonary tuberculosis in diabetic or immunocompromised patients often has an atypical pattern and distribution. To evaluate the CT features of pulmonary tuberculosis in diabetic or immunocompromised patients compared with patients without underlying disease, we performed this retrospective study. We reviewed conventional CT scans (n = 100) and high-resolution CT scans (n = 16) of the chest in 110 adult patients with active postprimary tuberculosis. ...
