Kinematic and dynamic models are used to create simplified, yet accurate representations of reality. In application to biological systems, there is often a choice on what level of complexity is appropriate for the model. This paper introduces a structured method for obtaining an accurate model that can represent the sit-to-stand motion and reproduce the associated contact forces in the standing phase. These models are generated from small datasets, just five measured sit-to-stand actions, and result in simple, physically realisable dynamic models...

BACKGROUND: Family presence during resuscitation is an emerging trend, yet it remains controversial, even in countries with relatively high acceptance of family presence during resuscitation among medical professionals. Family presence during resuscitation is not common in many countries, and medical professionals in these regions are unfamiliar with family presence during resuscitation. Therefore, this study predicted the medical professionals' intention to allow family presence during resuscitation by applying the theory of planned behaviour...

BACKGROUND: Tumor-associated macrophages (TAMs) support growth in most human cancers, with the notable exception of colorectal adenocarcinoma, in which TAM infiltration of primary tumors is correlated with a better outcome. The importance of TAMs in colorectal liver metastases (CLM) is unknown. METHODS: Using a tissue microarray of CLM resected at their institution from 1998 to 2000, the authors quantified immune marker expression by immunohistochemistry (IHC) using Metamorph Image Analysis software...

: Here comprehensive analysis was performed on the molecular and clinical features of colorectal carcinoma (CRC) harboring chromosome 20q amplification. Tumor and normal DNA from patients with advanced CRC underwent next generation sequencing (NGS) via MSK-IMPACT and a subset of case samples were subjected to high resolution microarray (Oncoscan). Relationships between genomic copy number and transcript expression were assessed with The Cancer Genome Atlas (TCGA) CRC data. Of the CRC patients sequenced (n=401) with MSK-IMPACT, 148 (37%) had 20q gain, and 30 (7%) had 20q amplification...

Mycobacterium abscessus, which is ubiquitous environmental organism, is more likely to cause pulmonary infection in the presence underlying lung disease and immunosuppression. We report a case of pulmonary disease due to coinfection of Mycobacterium tuberculosis (MTB) and Mycobacterium abscessus (M. abscessus) in an immunocompetent patient without underlying lung disease. Healthcare professionals should be aware of co-infection with MTB and M. abscessus, and treatment should be based on clinical suspicion and/or epidemiological circumstances...

Lung cancer remains the most diagnosed cancer in the world, with a high mortality rate and fewer therapeutic options. The most common lung cancer is non-small cell, which can consist of adenocarcinoma, squamous cell carcinoma and large cell lung carcinoma. As per all solid tumours, the changes that occur for the initiation and metastasis of lung cancer can be described using the EMT (epithelial mesenchymal transition). Cells progressing through EMT lose their epithelial cell characteristics, expressing more mesenchymal markers and are phenotypically different...

Disasters are unpredictable and often result in mass casualties. Limited medical resources often affect the response to mass casualty incidents, undermining the ability of responders to adequately protect all of the casualties. Thus, the injuries of casualties are classified in hopes of fully utilizing medical resources efficiently in order to save the maximum possible number of people. However, as opinions on casualty prioritization are subjective, disagreements and disputes often arise regarding allocating medical resources...

OBJECTIVES: Strategies are needed for the identification of a poor response to treatment and determination of appropriate chemotherapy strategies for patients in the early stages of neoadjuvant chemotherapy for breast cancer. We hypothesize that power Doppler ultrasound imaging can provide useful information on predicting response to neoadjuvant chemotherapy. METHODS: The solid directional flow of vessels in breast tumors was used as a marker of pathologic complete responses (pCR) in patients undergoing neoadjuvant chemotherapy...

Colorectal medullary carcinoma, recognized by the World-Health-Organization as a distinct histologic subtype, is commonly regarded as a specific entity with an improved prognosis and unique molecular pathogenesis. A fundamental but as-yet unaddressed question, however, is whether it can be diagnosed reproducibly. In this study, by analyzing 80 colorectal adenocarcinomas whose dominant growth pattern was solid (thus encompassing medullary carcinoma and its mimics), we provided a detailed description of the morphological spectrum from "classic medullary histology" to non-medullary poorly-differentiated histologies and demonstrated significant overlapping between categories...

Genetic variability in KRAS and EGFR predicts response to cetuximab in irinotecan refractory colorectal cancer. Whether these markers or others remain predictive in combination biologic therapies including bevacizumab is unknown. We identified predictive biomarkers from patients with irinotecan refractory metastatic colorectal cancer treated with cetuximab plus bevacizumab. Patients who received cetuximab plus bevacizumab for irinotecan refractory colorectal cancer in either of two Phase II trials conducted were identified...

Series of N-substituted carbazole analogues bearing an indole ring were synthesized as anti-methicillin-resistant Staphylococcus aureus (MRSA) agents from a molecular hybridization approach. The representative compound 19 showed an MIC = 1 μg/mL against a panel of MRSA clinical isolates as it possessed comparable in vitro activities to that of vancomycin. Moreover, compound 19 also exhibited MIC = 1 μg/mL activities against a recent identified Z172 MRSA strain (vancomycin-intermediate and daptomycin-nonsusceptible phenotype) and the vancomycin-resistant Enterococcus faecalis (VRE) strain...

The Cancer Genome Atlas data on colorectal carcinoma have provided a comprehensive view of the tumor's genomic alterations and their tumorigenic roles. Tumor morphology, however, has not been fully integrated into the analysis. The aim of this study was to explore relevant associations between tumor morphology and the newly characterized genomic alterations in colorectal carcinoma. Two hundred and seven colorectal carcinomas that had undergone whole-exome sequencing as part of The Cancer Genome Atlas project and had adequate virtual images in the cBioPortal for Cancer Genomics constituted our study population...

Square face or prominent mandibular angle is a major concern in Asian women. In class III patients, mandibular setback may lead to a wider lower face that is not preferred in Asian culture. In order to achieve better aesthetic outcomes, simultaneous mandibular contouring to reduce the width of the lower face is required for some patients. This article details the authors' procedures modified from Hunsuck techniques of sagittal split osteotomy. This modified Hunsuck technique provides an alternative option to obtain a desirable mandibular outline...

C-X-C chemokine receptor type 4 (CXCR4) is a receptor for a pleiotropic chemokine CXCL12. Previous studies have shown that the acute administration of the CXCR4 antagonist AMD3100 reduced neuroinflammation in stroke brain and mobilized bone marrow hematopoietic stem cells (HSCs). The purpose of this study was to characterize the neuroprotective and neurotrophic effect of a novel CXCR4 antagonist CX549. We demonstrated that CX549 had a higher affinity for CXCR4 and was more potent than AMD3100 to inhibit CXCL12 -mediated chemotaxis in culture...

BACKGROUND: Resection of colorectal liver metastasis (CRLM) can be curative. Predicting which patients may benefit from resection, however, remains challenging. Some microRNAs (miRNAs) become deregulated in cancers and contribute to cancer progression. We hypothesized that miRNA expression can serve as a prognostic marker of survival after CRLM resection. RESULTS: MiR-203 was significantly overexpressed in tumors of short-term survivors compared to long-term survivors...

Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

In the past six decades, the Kuwaiti population has been exposed to rapid transformation in the quality of diet intake, daily activities, and career types. This major socioeconomic shift was accompanied by the introduction of both communicable and noncommunicable chronic diseases afflicting people of all ages. This article aims to detect a relationship between sociocultural characteristics-such as physical activity, dietary habits, and smoking-and the prevalence of metabolic syndrome (MetS). A descriptive, cross-sectional survey was conducted among 262 male university students in Kuwait; participants were selected by using a convenient nonrandom opportunistic sample...

BACKGROUND: The ability to transform normal human cells into cancer cells with the introduction of defined genetic alterations is a valuable method for understanding the mechanisms of oncogenesis. Easy establishment of immortalized but non-transformed human cells from various tissues would facilitate these genetic analyses. RESULTS: We report here a simple, one-step immortalization method that involves retroviral vector mediated co-expression of the human telomerase protein and a shRNA targeting the CDKN2A gene locus...
