Severe Acute Pancreatitis: Gut Barrier Failure, Systemic Inflammatory Response, Acute Lung Injury, and the Role of the Mesenteric Lymph.

Severe acute pancreatitis (AP) often leads to distant organ dysfunction with a high morbidity and mortality rate. The most common and earliest organ to fail is the lungs, but the exact pathophysiological mechanisms underlying the disease are still unclear. No successful targeted therapy exists, and treatment is limited to organ supportive care. It is believed that the gut is involved in the develo

Supporting Design and Control of a Reversed-Phase Chromatography Step by Mechanistic Modeling

There is a need to design and understand control strategies for biopharmaceutical processes. The control strategy will influence the design space and process performance and should be chosen together with the operating point and design space. Mechanistic modeling is used to design and evaluate control strategies for product pooling in preparative chromatography. A kinetic dispersive model was cali

The forced oscillation technique is a sensitive method for detecting obstructive airway disease in patients with primary Sjögren's syndrome.

Objectives: To study signs of obstructive airway disease (OAD) in patients with primary Sjögren's syndrome (pSS) using the forced oscillation technique (FOT). Method: Thirty-seven female pSS patients (median age 64, range 38-77 years) without previous physician-diagnosed OAD, participating in a longitudinal follow-up study of pulmonary function, and 74 female population-based controls (median age

A 59-kd renal antigen as a new target for rapidly progressive glomerulonephritis

Anti-glomerular basement membrane (anti-GBM) antibodies are the hallmark of anti-GBM disease, which is characterized by rapidly progressive glomerulonephritis. We describe the case of a 58-year-old woman who presented with rapidly progressive glomerulonephritis with typical anti-GBM staining found by means of direct immunofluorescence microscopy, associated with linear immunoglobin G deposits on t

Preliminary observations of sperm storage in Adalia bipunctata (Coleoptera : Coccinellidae): sperm size and number

Sperm storage in Adalia bipunctata (L.) (Coleoptera, Coccinellidae) was examined and compared between diapausing and non-diapausing females. We observed that non-diapausing females store on average 13,688 (+/-722, S.E.) sperm in their spermatheca and that every female examined had sperm in storage (n = 16). In contrast, most diapausing females had empty spermatheca and only two had sperm in storag

Neoglycoconjugates of mannan with bovine serum albumin and their interaction with lectin concanavalin A

Neoglycoconjugates were prepared from mannan isolated from yeast Saccharomyces cerevisiae and activated by periodate oxidation to create aldehyde groups. Various degrees of oxidation introduced 11-28 aldehyde groups per mannan molecule and simultaneously resulted in a molar mass decrease from 46 to 44.5-31 kDa. The activated mannans were subsequently conjugated with bovine serum albumin forming ne

Nanowire growth and dopants studied by cross-sectional scanning tunnelling microscopy

Using a crystalline embedding scheme it has recently become possible to study free-standing III - V nanowires with cross-sectional scanning tunnelling microscopy (XSTM). In the present paper we discuss how this novel method can be used for direct atomically resolved imaging of the interior of nanowires. We will focus in particular on two areas where this method provides unique possibilities. First

Seasonal photoreactivity of dissolved organic matter from lakes with contrasting humic content

We studied seasonal variability in photodegradation of dissolved organic carbon (DOC) resulting from artificial ultraviolet-A (UV-A) and UV-B irradiation. Water samples were taken approximately monthly from the surface layers of two oligotrophic lakes with contrasting humic content, situated in southern Sweden. Lake water was filter-sterilized (0.2 μm) and exposed to artificial UV radiation in qua

Up-regulation of thromboxane A(2) receptor expression by lipid soluble smoking particles through post-transcriptional mechanisms.

Atherosclerosis is a key factor in vascular disease, and cigarette smoking is a well-known risk factor that may induce an inflammatory response and enhance plaque formation in arteries. Thromboxane (Tx) is one key inflammatory mediator involved in the pathogenesis of cardiovascular disease. The present study was designed to test if lipid soluble smoking particles (DSP) enhance TxA(2) receptor (TP)

Why are small seeds dispersed through animal guts: large numbers or seed size per se?

Long-distance dispersal of seeds is an important process in metapopulation dynamics and in plant migrations, but at the same time extremely difficult to observe or quantify directly. If seed dispersal ability were related to attributes of seeds or motherplants, long-distance seed dispersal would be predictable by indirect approximation using easy-to-measure traits. Seed size has been suggested to

A retrospective analysis of health care costs for bone fractures in women with early-stage breast carcinoma

BACKGROUND. in this retrospective data base study, the authors sought to estimate direct costs for bone fractures in women age 65 years with early-stage breast carcinoma and to compare those costs with treatment costs for bone fractures in older women without early-stage breast carcinoma. METHODS. Direct costs for bone fractures in patients with early-stage breast carcinoma, which consist of exces

Low Recurrence Rate After Laparoscopic (TEP) and Open (Lichtenstein) Inguinal Hernia Repair A Randomized, Multicenter Trial With 5-Year Follow-Up

Objectives: To compare a laparoscopic (totally extraperitoneal patch (TEP)) and an open technique (Lichtenstein) for inguinal hernia repair regarding recurrence rate and possible risk factors for recurrence. Summary Background Data: Laparoscopic hernia repair has been introduced as an alternative to open repair. Short-term follow-tip suggests benefits for those patients operated with a laparoscopi

Dynamics of cytoskeletal proteins in developing pine ectomycorrhiza

Mycorrhizal short roots of Pinus contorta Dougl. ex Loud colonized by Suillus variegatus (Sow. ex Fr.) O. Kuntze or Paxillus involutus (Batsch) Fr. were collected 1->60 days after fungal contact. The proteins of the inoculated roots were extracted, electrophoretically separated, blotted and immunostained for alpha-tubulin and actin. The development of the mycorrhiza was also followed microscopical

Influence of the particle size and particle size ratio on the morphology and viscoelastic properties of bimodal hard/soft latex blends

The morphology and viscoelastic properties of films prepared from bimodal latex blends containing equal weight fractions of soft and hard latex particles were investigated as a function of the particle sizes and the particle size ratio (soft particle diameter/hard particle diameter). Minimum film formation temperature (MFT) measurements were associated with transmission electron microscopy (TEM) t

Complex Nature of the Genome in a Wine-spoilage Yeast, Dekkera bruxellensis.

When the genome organization of thirty native isolates belonging to a wine-spoilage yeast Dekkera/Brettanomyces bruxellensis, a distant relative of Saccharomyces cerevisiae, was examined, the number of chromosomes varied drastically, from 4 to at least 9. When single gene probes were used in Southern analysis, the corresponding genes usually mapped to at least two chromosomal bands, excluding a si
