Characterization of two novel cutaneous human papillomaviruses, HPV93 and HPV96.

Two novel human papillomaviruses (HPVs), HPV93 and HPV96, with genomes of 7450 and 7438 bp, respectively, are described. The Ll open reading frame of HPV93 showed highest identity to HPV24 (79%) and that of HPV96 had highest identity to HPV92 (71 %). Real-time PCR for HPV92, 93 and 96 on stripped biopsies from tumours and healthy skin from 269 immunocompetent patients found HPV DNA in 2.6 % of tum

Computational analysis of heat transfer enhancement in square ducts with V-shaped ribs: Turbine blade cooling

Experimental studies have revealed that both downstream and upstream pointing V-shaped ribs result in more heat transfer enhancement than transverse straight ribs in ducts. However, based on the available experimental results, contradiction exists whether the upstream or the downstream pointing V-shaped ribs orientation is superior for better enhancement in heat transfer. Further investigations ar

Difficulties in performing leisure activities among persons with newly diagnosed rheumatoid arthritis: a prospective, controlled study.

Objective. To compare leisure activities and associated factors in a group with recent onset RA and matched community-derived controls, to examine whether leisure activities are altered during the early years of disease and to seek predictors. Methods. One hundred and forty-seven consecutive persons with early RA were followed for 0.9-5.9 yr. One hundred and forty-four RA patients were compared cr

Safety and efficacy of a high cumulative dose of salbutamol inhaled via Turbuhaler or via a pressurized metered-dose inhaler in patients with asthma

An open, crossover and randomized study was carried out to compare the safety and efficacy of salbutamol inhaled using the dry-powder inhaler Turbuhaler, and using a pressurized metered-dose inhaler (pMDI). Twelve patients with moderate to severe asthma, aged 47-68 years, were included in the study. On two separate days, patients received a total dose of 1600 micrograms of salbutamol administered

Skewing Towards Neuroendocrine Phenotype in High Grade or High Stage Androgen-Responsive Primary Prostate Cancer

Objective: The prognostic influence of neuroendocrine (NE) differentiation in prostate cancer patients is not yet properly established. In a series of primary hormone-naive prostate cancers from a patient population that underwent radical prostatectomy, we wanted to determine the relationship between NE phenotype expression and Gleason sum, disease stage, and serum PSA concentration. Methods: Ch

Papillomavirus type 16 E6/E7 and human telomerase reverse transcriptase in esophageal cell immortalization and early transformation

Infection with high-risk human papillomavirus (HPV) has been implicated in the pathogenesis of esophageal squamous cell carcinoma, and up-regulation of telomerase in esophageal adenocarcinoma. We immortalized normal esophageal epithelial cells by over-expression of the HPV16 E6/E7 and human telomerase reverse transcriptase (hTERT) genes. HPV16 E6/E7-induced immortalization was accompanied by reduc

Induction of differentiation in acute promyelocytic leukemia cells (HL-60) by the verticillin derivative Sch 52900

The HL-60 cell line, derived from a patient with acute promyelocytic leukemia, is a widely used model system to study the cellular and molecular events involved in differentiation of leukemic cells. In a screening for inducers of differentiation of HL-60 cells, cultures of Gliocladium strain 4-93 were found to produce Sch 52900, a previously isolated diketopiperazine (Chu et al,. J. Antibiotics 48

Applications of the eater-food model to predator-prey-food cycles

This note gives five applications of the eater-food interaction model (Garding 2005) where cycle length is a function of the eater average birth rate defined as the inverse of average life span. The model extends to an analysis of predator-prey-food cycles (Garding 2000). Here the cycle length is the same as that of en eater-food interaction whose average 'birth rate' is the sum of the average bir

Mapping of the "intervention channels" as a part of the community diagnosis process of the Stockholm Cancer Prevention Program (SCPP)

The Stockholm Cancer Prevention Program is to our knowledge the first community intervention program in the world aiming of a reduction in the incidence of cancer. A community diagnosis model has been used in the planning. A thorough description of different organizations in the local communities of Stockholm has been made. A model for describing the organizations or collaborators has been worked

Sexual problems in men with prostate cancer in comparison with men with benign prostatic hyperplasia and men from the general population

In a questionnaire study, men with prostate cancer (n = 155) or benign prostatic hyperplasia (n = 131) identified more sexual problems than did men from the general population (n = 129). Sexual dysfunction was acknowledged regarding sexual pleasure and attraction, erectile function and sexual satisfaction and sexual performance. Lowered rates of sexual desire, pleasure and attraction were found wh

Treatment delay and prognosis in invasive bladder cancer.

Purpose: We studied treatment delay, and the impact on disease specific survival and stage progression in a series of patients who had undergone cystectomy. Materials and Methods: All 141 patients underwent radical cystectomy between 1990 and 1997 due to locally advanced bladder cancer. Treatment delay was defined as time from pathological confirmation of invasive disease to performance of cystect

Reef biostromes and related facies from the Middle Silurian of Gotland, Sweden

Reef biostromes and related facies from the upper part of Wenlock and from Ludlow were investigated in order to account for their formation, their palaeoecology and biology. In the Hemse Group of Ludlow age, all studied biostromes comprise a low diversity fauna where one or few species dominates. These biostromes are divided into Kuppen type biostromes, Grogarnshuvud type biostromes and Sjaustreha

Systemic alendronate prevents resorption of necrotic bone during revascularization. A bone chamber study in rats

Background: Avascular necrosis of bone (osteonecrosis) can cause structural failure and subsequent deformation, leading to joint dysfunction and pain. Structural failure is the result of resorption of necrotic bone during revascularization, before new bone has formed or consolidated enough for loadbearing. Bone resorption can be reduced by bisphosphonates. If resorption of the necrotic bone could
