Establishing that a cell line was derived from a single cell progenitor and defined as clonally-derived for the production of clinical and commercial therapeutic protein drugs has been the subject of increased emphasis in cell line development (CLD). Several regulatory agencies have expressed that the prospective probability of clonality for CHO cell lines is assumed to follow the Poisson distribution based on the input cell count. The probability of obtaining monoclonal progenitors based on the Poisson distribution of all cells suggests that one round of limiting dilution may not be sufficient to assure the resulting cell lines are clonally-derived...

This cross-sectional study was conducted on 15 infants and toddlers with chronic liver disease (CLD) to validate arm anthropometry as an accurate measure of body composition (BC) compared to dual-energy X-ray absorptiometry (DXA) and to predict growth from BC.The z-score means of the anthropometric indicators were < -2SD, except for body fat index and subscapular skinfold which were between -2 and +2 SD. Fat mass was predicted by arm adiposity indicators and fat-free mass by arm muscle area. Bone mineral content explained 87% of variation in length...

PURPOSE: The pedicled, descending-branch muscle-sparing latissimus dorsi (MSLD) flap has been widely used for breast reconstruction following total mastectomy. However, the superiority of the MSLD flap compared to the conventional latissimus dorsi (CLD) flap in preventing seroma formation has not been demonstrated. This study compares the morbidities related to seroma formation following pedicled MSLD flap and CLD flap breast reconstruction. METHODS: A total of 15 women who underwent partial mastectomy and immediate partial breast reconstruction with MSLD flaps were compared with 15 women under identical conditions with CLD flap breast reconstruction...

Tight junction (TJ) is one of the cell-cell junctions and known to have the barrier and fence functions between adjacent cells in both simple and stratified epithelia. We examined the distribution pattern, constitutive proteins, and permeability of TJ in the stratified squamous epithelium of the palatal mucosa of mice. Ultrastructural observations based on the ultrathin section and freeze-fracture methods revealed that poorly developed TJs are located at the upper layer of the stratum granulosum. The positive immunofluorescence of occludin (OCD), claudin (CLD)-1 and -4 were localized among the upper layer of the stratum granulosum showing a dot-like distribution pattern...

Cholestatic liver diseases (CLDs) encompass a variety of disorders of bile formation and/or flow which generally result in progressive hepatobiliary injury and ultimately end-stage liver disease. Many patients with CLD are diagnosed between the ages of 20-50 years, a particularly productive period of life professionally, biologically, and in other respects; it is not surprising, thus, that CLD is often associated with impaired health-related quality of life (HRQOL) and uncertainty regarding implications for and outcomes of pregnancy...

Cirrhosis has many complications regardless of the aetiology. Complications include splenomegaly, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome and hepatocellular carcinoma and also linked to abnormalities in the endocrine system, including abnormal sex hormone metabolism, thyroid disease, osteoporosis, and, most recently identified, adrenal insufficiency. This prospective cohort study was done to evaluate the impact of adrenocortical insufficiency on clinical parameters in haemodynamically stable cirrhotic patients with ascites and had been performed at the inpatient of GHPD Department, BIRDEM, Dhaka, Bangladesh from April 2011 to March 2012...

INTRODUCTION: Current clinical practice guidelines suggest that patients with ulcerative colitis (UC) hospitalized because of a disease flare should be offered a normal diet, unless such a diet is not tolerated. Studies of hospitalized patients have demonstrated iatrogenic malnutrition from unjustified or inappropriate nil per os (NPO) or clear liquid diet (CLD) orders. In this study, we aim to characterize the burden of this problem in hospitalized patients with UC. METHODS: We conducted a retrospective cohort study of all patients with UC admitted to the gastroenterology service or the general internal medicine service at a tertiary, academic hospital between January 2009 and December 2014, with a length of stay between 2 and 30 days...

BACKGROUND/PURPOSE: Controlled attenuation parameter (CAP) is a method for measuring steatosis based on FibroScan. Despite observer dependency, ultrasound (US) robustly diagnoses moderate and severe steatosis. Here, we aimed to evaluate the correlation of CAP with US-identified steatosis in real-world clinical practice. METHODS: CAP and US were performed for 1554 chronic liver disease (CLD) patients. CAP was performed by two technicians, and US was performed by 30 hepatologists...

BACKGROUND: Intestinal microbiota are critical determinants of obesity and metabolic disease risk. In previous work, we showed that deletion of the cytoplasmic lipid droplet (CLD) protein perilipin-2 (Plin2) modulates gut microbial community structure and abrogates long-term deleterious effects of a high-fat (HF) diet in mice. However, the impact of Plin2 on microbiome function is unknown. RESULTS: Here, we used metatranscriptomics to identify differences in microbiome transcript expression in WT and Plin2-null mice following acute exposure to high-fat/low-carbohydrate (HF) or low-fat/high-carbohydrate (LF) diets...

PURPOSE: To provide updated radiation dose from diagnostic exams performed for pregnant patients suspected of pulmonary embolism (PE) using the recently developed BREP phantoms of pregnant woman and the fetus. Also to challenge the validity of current recommendations suggest that ventilation/perfusion (V/Q) single photon emission computed tomography (SPECT) vs. computed tomography pulmonary angiography (CTPA) should be considered for diagnosis of PE in radiosensitive groups such as pregnant women...

Increased attention on "complexity" in health systems evaluation has resulted in many different methodological responses. Theory-driven evaluations and systems thinking are two such responses that aim for better understanding of the mechanisms underlying given outcomes. Here, we studied the implementation of a performance-based financing intervention by the Belgian Technical Cooperation in Western Uganda to illustrate a methodological strategy of combining these two approaches. We utilized a systems dynamics tool called causal loop diagramming (CLD) to generate hypotheses feeding into a theory-driven evaluation...

It was thought that a high International Normalized Ratio (INR) predicted bleeding in patients with chronic liver disease (CLD) and patients were 'autoanticoagulated'. Contrary to this belief, while patients with CLD experienced bleeding, they also developed thromboses. In the last decade, the prevailing literature challenged the idea that an elevated INR increased bleeding risk. The global assays of coagulation such as: thromboelastography (TEG)/rotational thromboelastometry (ROTEM) and thrombin generation assays (TGA) provide additional insight into coagulation processes...

It is already a proven fact that there exists a relationship between CLD (chronic liver disease) and kidney disease but still there is no available combined animal model of liver and kidney fibrosis on the same animal. An animal model is one of the important research tools in the field of medical science because it is important to build a model that can simulate the disease condition so that the particular disease can be studied. Therefore, the aim of this study is to build a less expensive, less time consuming, and reproducible model of hepatorenal fibrosis on rats...

OBJECTIVE: This study aimed to evaluate the utility of magnetic resonance elastography (MRE) as a non-invasive method for predicting ascites in patients with chronic liver disease (CLD). METHODS: A total of 208 CLD patients underwent MRE to measure liver stiffness (LS) at our institution from March 2013 to June 2015. We evaluated the diagnostic performance of MRE for predicting the presence of ascites using receiver-operating characteristic (ROC) curve analysis and compared the performance with that of serum fibrosis markers...

In objective assessment of image quality, an ensemble of images is used to compute the 1st and 2nd order statistics of the data. Often, only a finite number of images is available, leading to the issue of statistical variability in numerical observer performance. Resampling-based strategies can help overcome this issue. In this paper, we compared different combinations of resampling schemes (the leave-one-out (LOO) and the half-train/half-test (HT/HT)) and model observers (the conventional channelized Hotelling observer (CHO), channelized linear discriminant (CLD) and channelized quadratic discriminant)...

Optimal management of large and locally advanced hepatocellular carcinoma (HCC) remains a clinical challenge especially in patients with chronic liver disease (CLD). We present our experience of major liver resection for large and locally advanced HCC. Prospectively collected data of patients with large and locally advanced HCC who underwent major liver resection between March 2011 and May 2015. The outcome measures of interest were the characteristics of tumor, surgical outcome, and overall as well as disease-free survival...
