Control of junB and extracellular matrix protein expression by transforming growth factor-beta 1 is independent of simian virus 40 T antigen-sensitive growth-sensitive growth-inhibitory events

Treatment of Mv1Lu mink lung epithelial cells with transforming growth factor-beta 1 (TGF-beta 1) prevents phosphorylation of the retinoblastoma susceptibility gene product, RB, in late G1 phase of the cell cycle, which is thought to retain RB in a growth-suppressive state. This effect is paralleled by cell cycle arrest in late G1 (M. Laiho, J. A. DeCapric, J. W. Ludlow, D. M. Livingston, and J. M

Pre-Diagnostic Levels of Anionic Trypsinogen, Cationic Trypsinogen, and Pancreatic Secretory Trypsin Inhibitor in Relation to Pancreatic Cancer Risk.

Background/Aims: Experimental studies have suggested that trypsinogen may enhance tumor progression and that the ratio between anionic trypsinogen and cationic trypsinogen (HAT/HCT) and between the sum of trypsinogens and pancreatic secretory trypsin inhibitor (PSTI) ((HAT + HCT)/PSTI) are disturbed in patients with pancreatic cancer. The aim of this study was to investigate if pre-diagnostic leve

How many trials are needed to achieve performance stability of the Timed Up & Go test in patients with hip fracture?

OBJECTIVE: To examine the number of trials needed to achieve performance stability of the Timed Up & Go (TUG) test using a standardized walking aid in patients with hip fracture who are allowed full weight bearing (FWB). DESIGN: Prospective methodologic study. SETTING: An acute 14-bed orthopedic hip fracture unit. PARTICIPANTS: Patients (N=122; 89 women, 33 men) with hip fracture wit

Lifetime measurements in CeI, CeII, and CeIII using time-resolved laser spectroscopy with application to stellar abundance determinations of cerium

Radiative lifetimes of two levels in Ce I, eight levels in Ce rr, and nine levels in Ce III have been measured using the time-resolved laser-induced fluorescence technique. Free cerium atoms and singly and doubly ionized ions were obtained in a laser-produced plasma. A narrow bandwidth UV laser pulse was employed to selectively populate the short-lived upper levels and the lifetime values were eva

Experiences of relocation in dementia care from the perspective of six care workers.

Experiences of relocation in dementia care from the perspective of six care workers. International Journal of Older People Nursing6, 93-101 doi: 10.1111/j.1748-3743.2010.00246.x Background. Relocation of persons with dementia might be considered when quality of care cannot be sustained due to increasing needs. Relocation has been studied from the aspects of mortality and morbidity. Aim. To explore

Meta-analysis of Cancer Gene Profiling Data.

The simultaneous measurement of thousands of genes gives the opportunity to personalize and improve cancer therapy. In addition, the integration of meta-data such as protein-protein interaction (PPI) information into the analyses helps in the identification and prioritization of genes from these screens.Here, we describe a computational approach that identifies genes prognostic for outcome by comb

Directional stability of an originally straight crack

The directional stability of an originally straight crack under symmetric remote loading is studied after introduction of an infinitesimal disturbance at one or both tips of the crack. The crack is assumed to grow slowly under vanishing mode II stress intensity factor. Directional stability is defined to prevail if the angle formed by the straight line between the crack tips and the original crack

Verapamil Inhibits L-type Calcium Channel Mediated Apoptosis in Human Colon Cancer Cells.

PURPOSE: Treatment with calcium channel blockers have been associated with increased colon cancer mortality in epidemiologic studies. We examined the potential expression and function of calcium channels in two human colon cancer cell lines. METHODS: Both primary (collected at operation) and commercially-available human colon cancer cell lines were used. The colon cancer cells were incubated with

Environmental Philosophy in Christianity and Buddhism: Meeting Places for a Dialogue

Questions concerning the human–nature relationship have received attention both within contemporary Christianity and Buddhism. Since the twentieth century an interesting and fruitful dialogue has been going on between the two religions. This article describes and discusses possible themes for a Buddhist–Christian dialogue on issues of environmental philosophy. The theoretical starting-point is the

Sarcomatoid conversion of clear cell renal cell carcinoma in relation to epithelial-to-mesenchymal transition.

Approximately 8% of clear cell renal cell carcinoma cases contain regions of radically different morphology, demonstrating a mesenchymal appearance histologically resembling sarcomas. These biphasic neoplasms are called sarcomatoid clear cell renal cell carcinoma. Patients diagnosed with sarcomatoid clear cell renal cell carcinoma face a considerably worse prognosis due to an increased propensity

The validity of DSM-IV dissociative disorders categories in SW Uganda

There is little systematic research on the cross-cultural validity of the dissociative disorders, especially in non-western countries. This study evaluates the fit of the DSM-IV classification and concepts of these disorders with local concepts, experiences and local presentations in south-west Uganda. We conducted focus group discussions with medical students, traditional healers, religious leade

Different Images of Science - A study of how science is constituted in exhibitions

Popular Abstract in Swedish Inom science och technology centre (STC)-rörelsen finns det uttalade mål och ambitioner att öka allmänhetens intresse och förståelse för naturvetenskap. Samtidigt ifrågasätter många forskare de val som görs vad gäller utställningarnas innehåll och hävdar att det är vanligt att en alltför produktorienterad syn på naturvetenskap presenteras. Men vilka bilder och aspekter Within the science and technology centre (STC) movement there exists explicit aims and ambitions to enhance visitors’ interest in and knowledge about science. Meanwhile, several researches question the choice of the scientific content in exhibitions when arguing that a too unproblematic view of science commonly is presented. But what images and aspects of science are visitors actually confronted w

Electrophysiological evaluation and visual outcome in patients with central retinal vein occlusion, primary open-angle glaucoma and neovascular glaucoma.

Purpose: To evaluate patients with central retinal vein occlusion (CRVO) and neovascular glaucoma (NVG) using electrophysiology in order to gain better understanding of visual outcome and risk factors, such as previously diagnosed primary open-angle glaucoma (POAG). Methods: Eighty-three patients (83 eyes) initially presenting with CRVO and examined with full-field electroretinography (ERG) within

Predicting the risk of malignancy in adnexal masses based on the Simple Rules from the International Ovarian Tumor Analysis (IOTA) group.

Accurate methods to preoperatively characterize adnexal tumors are pivotal for optimal patient management. A recent meta-analysis concluded that the International Ovarian Tumor Analysis (IOTA) algorithms such as the Simple Rules are the best approaches to preoperatively classify adnexal masses as benign or malignant. We sought to develop and validate a model to predict the risk of malignancy in ad
