Falls are the cause for more than half of the injury-related hospitalizations among older people. Accurate assessment of individuals' fall risk could enable targeted interventions to reduce the risk. This paper presents a novel method for using wearable accelerometers to detect early signs of deficits in balance from gait. Gait acceleration data were analyzed from 35 healthy female participants (73.86±5.40 years). The data were collected with waist-mounted accelerometer and the participants performed three supervised balance tests: Berg Balance Scale (BBS), Timed-Up-and-Go (TUG) and 4m walk...

BACKGROUND: Data on genotype-phenotype correlation in children is limited. Hence, we studied the prevalence of germline mutations and genotype-phenotype correlation in children with pheochromocytoma (PCC)/paraganglioma (PGL) and compared it with adult PCC/PGL cohort. METHODS: A total of 121 consecutive, unrelated, index PCC/PGL patients underwent genetic testing for five PCC/PGL susceptibility genes (RET, VHL, SDHB, SDHD and SDHC) and were evaluated for clinical diagnosis of neurofibromatosis type1 (NF1)...

Cyclodextrin capillary electrophoresis methods (CD-CZE) were developed for complete enantiomeric and diastereoisomeric separations of a series of ten dihydropyridone analogues, of which eight were neutral, one was anionic and one was cationic. Ten different systems comprising one or two cyclodextrins were found to successfully separate the isomers thanks to a screening approach. Among the tested cyclodextrins, HS-γ-CD, either in a single or in a dual system, in a phosphate buffer using capillaries dynamically coated with polyethylene oxide (PEO), and SBE-β-CD, either in a single or in a dual system, in a borate buffer using uncoated capillaries, were the most selective selectors...

BACKGROUND: An insecticide screening effort identified N-(4-bromophenyl)-4,6-bis(2,2,2-trifluoroethoxy)-1,3,5-triazine-2-amine as having weak potency against two Lepidopteran species, Helicoverpa zea and Spodoptera exigua. A structure activity relationship study about the trifluoroethoxy substituents and the aniline of this compound was carried out in an effort to improve insecticidal potency. RESULTS: Initially, a series of analogs bearing various substituents on the aniline were prepared and the insecticidal potency was evaluated against Helicoverpa zea and Spodoptera exigua in greenhouse diet feeding assays...

Rotavirus is the leading worldwide cause of gastroenteritis in children under five years of age. Even though there are some available vaccines to prevent the disease, there are limited strategies for challenging diarrhea induced by rotavirus infection. For this reason, researchers are constantly searching for other approaches to control diarrhea by means of probiotics. In order to demonstrate the ability of some probiotic bacteria to interfere with the in vitro rotavirus infection in MA104 cells, strains of Lactobacillus sp...

The malignant transformation of astrocytoma may result from the accumulation of multiple genetic alterations. Current research shows that diffuse astrocytoma (AIIs, WHO grade II) is inherently predisposed to recur locally, and to spontaneously progress to anaplastic astrocytoma (AAIIIs, WHO grade III) and eventually secondary glioblastoma (sGBMIVs, WHO grade IV). The aim of the study was to identify and validate the important gene(s) associated with malignant progression and poor prognosis of astrocytoma. Average expression levels of 82 samples (35 AIIs, 13 AAIIIs and 34 sGBMIVs) were compared to each other through no-paired student test...

While participation in cancer screening can facilitate early detection and improved prognosis, all screening tests yield some proportion of abnormal test results which are later determined benign. These false positive (FP) results can negatively impact affective, cognitive, and behavioral outcomes. Women participating in an ovarian cancer (OC) screening program receiving an abnormal screening test result (n = 375) were matched with women receiving normal results (n = 375). Both groups completed a baseline and 1- and 4-month follow-up assessments...

Receptor tyrosine kinases (RTK) are important cell signaling molecules that influence many cellular processes. Receptor tyrosine kinase such as orphan receptor 1 (Ror1), a surface antigen, is a member of the RTK family of Ror, which plays a crucial role in cancers that have high-grade histology. As Ror1 has been implicated to be a potential target for cancer therapy, we selected this protein for further investigation. The secondary and tertiary structure of this protein was determined, which revealed that this protein contained three β-sheets, seven α-helices, and coils...

Circulating tumor cells (CTCs) have a crucial role in the clinical outcome of cancer patients. Detection of non-small cell lung cancer (NSCLC) using an antibody against epithelial cell adhesion molecule (EpCAM) in captured CTCs has low sensitivity; the loss of epithelial markers leads to underestimation of CTCs with mesenchymal phenotype. We propose a new approach for detection of viable CTCs, including those with epithelial-mesenchymal transition status (EMT-CTCs), using the new telomerase-specific replication-selective adenovirus (OBP-1101), TelomeScan F35...

INTRODUCTION: Evaluation studies of population-based tobacco control interventions often rely on large-scale survey data from numerous respondents across many geographic areas to provide evidence of their effectiveness. Significant challenges for survey research have emerged with the evolving communications landscape, particularly for surveying hard-to-reach populations such as youth and young adults. This study combines the comprehensive coverage of an address-based sampling (ABS) frame with the timeliness of online data collection to develop a nationally representative longitudinal cohort of young people aged 15-21...

A diagnostic test that is reliable, sensitive, and applicable in the field is extremely important in epidemiological surveys, during medical treatment for schistosomiasis, and for the control and elimination of schistosomiasis. The Helmintex (HTX) method is based on the use of magnetic beads to trap eggs in a magnetic field. This technique is highly sensitive, but the screening of fecal samples consumes lots of time, thus delaying the results, especially in field studies. The objective of this work was to determine the effects of incorporation of the detergent Tween-20 into the method in an attempt to decrease the final pellet volume produced by the HTX method as well as the use of ninhydrin to stain the Schistosoma mansoni eggs...

In assisted reproduction, embryos derived from monopronucleated (1PN) zygotes are considered abnormal and unsuitable for clinical use. Outcomes of 1PN-derived embryos designated for preimplantation genetic screening (PGS) were analysed. These embryos, especially from intracytoplasmic sperm injection (ICSI), were found to have a low developmental potential; 1PN and 2PN day 5 blastocyst development for IVF was 14.8% versus 36.4% (P < 0.0001), and for ICSI, 6.6% versus 34.0% (P < 0.0001), respectively. With the use of comparative genomic hybridization or next-generation sequencing, PGS was successfully carried out for 74 IVF and 32 ICSI 1PN-derived blastocysts, revealing adjusted abnormality rates of 39...

Malaria is a mosquito-borne disease caused by five species of Plasmodium parasites. Accurate diagnosis of malaria plays an essential part in malaria control. With traditional diagnostic methodologies, malaria control programs have achieved remarkable success during the past decade, and are now heading toward malaria elimination in many areas. This new situation, however, calls for novel diagnostics with improved sensitivity, throughput, and reduced cost for active screening of malaria parasites, as all transfected individuals have to be identified in order to block transmission...

BACKGROUND: Onset of canine transitional cell carcinoma (TCC) and prostatic carcinoma (PCA) is usually insidious with dogs presenting at an advanced stage of the disease. A biomarker that can facilitate early detection of TCC/PCA and improve patient survival would be useful. S100A8/A9 (calgranulin A/B or calprotectin) and S100A12 (calgranulin C) are expressed by cells of the innate immune system and are associated with several inflammatory disorders. S100A8/A9 is also expressed by epithelial cells after malignant transformation and is involved in the regulation of cell proliferation and metastasis...

Background MRSA represents a considerable health threat to orthopaedic patients. Throughout the last decade, livestock-associated MRSA emerged increasingly in livestock all over Europe. LA-MRSA broke the species barrier, colonizing and causing infections in humans. Nevertheless, to date there are no studies concerning livestock-associated MRSA and orthopaedic patients. Therefore, we aimed to investigate the prevalence of LA-MRSA in a regional orthopaedic department localized in an area with high-density livestock...

BACKGROUND: Transesophageal echocardiography (TEE) is a valuable monitor for patients undergoing cardiac and noncardiac surgery as it allows for evaluation of cardiovascular compromise in the perioperative period. It is challenging for anesthesiology residents and medical students to learn to use and interpret TEE in the clinical environment. A critical component of learning to use and interpret TEE is a strong grasp of normal cardiovascular ultrasound anatomy. METHODS: Fifteen fourth-year medical students and 15 post-graduate year (PGY) 1 and 2 anesthesiology residents without prior training in cardiac anesthesia or TEE viewed normal cardiovascular anatomy TEE video clips; participants were randomized to learning cardiac anatomy in generative retrieval (GR) and standard practice (SP) groups...
