Background The prognostic values of weight loss and body mass index (BMI) in esophageal carcinoma remain controversial. This study aimed to evaluate the impacts of weight loss on the survival of patients undergoing radical surgery and adjuvant chemotherapy. Methods The medical records of 189 consecutive patients with nonmetastatic esophageal carcinoma treated in our hospital between January 2...

The ratio of nonsynonymous substitution rate (Ka) to synonymous substitution rate (Ks) is widely used as an indicator of selective pressure at sequence level among different species, and diverse mutation models have been incorporated into several computing methods. We have previously developed a new gamma-MYN method by capturing a key dynamic evolution trait of DNA nucleotide sequences, in cons...

BACKGROUND Although weight loss is common in nasopharyngeal carcinoma (NPC) patients receiving radiotherapy, the prognostic influence of weight loss and its impact modified by body mass index (BMI) are still unclear. METHODS 2433 NPC patients receiving radical radiotherapy at Sun Yat-sen University Cancer Center from November, 2000 to December, 2004 were enrolled. Weight change during radiati...

In the general matter composition where the multiple scalar fields and the multiple perfect fluids coexist, in the leading order of the gradient expansion, we construct all the solutions of the nonlinear evolutions of the locally homogeneous universe. From the momentum constraint, we derive the constraints which the solution constants of the locally homogeneous universe must satisfy. We constru...

INTRODUCTION Medical school curricula in the United States have been more recently focusing on the early integration of clinical sciences and clinical experiences into medical students’ preclinical years. For many medical students, the common mode of instruction for developing the procedural skill of laceration repair is largely from live workshop training requiring a significant amount of phys...

Variation in human cochlear dimension must be considered when selecting a patient-suitable electrode array for coch-lear implantation. A promising way of cochlear duct length (CDL) prediction utilizes statistical properties of variations in cochlear morphology. In this work, CDL values estimated by statistically derived equations were validated using three-dimensional measurements in micro-CT d...

We aimed to determine the effects of water level and habitat heterogeneity on gastropod fauna in littoral zone, differentiation functional feeding guilds (FFG) gastropods. Two periods were analyzed: 2012 (low level, LWL) 2013 (high HWL) zone two shallow waterbodies (Sutla backwater, NW Croatia). Waterbody S1, covered with Ceratophyllum demersum, was sampled macrophyte stands, benthal area, whil...

This paper presents the results of research on the use of smartphone sensors (namely, GPS and accelerometers), geospatial information (points of interest, such as bus stops and train stations) and machine learning (ML) to sense mobility contexts. Our goal is to develop techniques to continuously and automatically detect a smartphone user's mobility activities, including walking, running, drivin...
