During the last few decades myoelectric prostheses were generally provided for adolescent or adult patients. Since 1991 the availability of smaller sized electric hands in conjunction with technical improvements enabled the introduction of myoelectric prostheses for preschool children.However, this progress remained wi…

In the last few years, an enormous progress has been achieved in the treatment of Colorectal Cancer due to a better know ledge of the biology, natural history, prevention and treatment of colon and rectum adenocarcinoma. Genetic alterations produce changes in thecolonic mucosa that lead to the formation of adenoma and…

The objective of this study was to describe trends in the use of hormone replacement therapy (HRT) in the United States by demographic, life-style, and heart disease risk factors. Data were obtained from the Epidemiologic Followup Study to the First National Health and Nutrition Examination Survey, a nationally represe…

The authors report the surgical management of 19 patients with chronic intestinal ischemia over the last ten years. There were 11 women and 8 men (mean age 59 years). Most patients (13/19) suffered from widespread generalized atheromatosis. Fifteen patients had symptoms which were mostly aspecific and insidious in onse…

AIMS AND BACKGROUND: The aim of the study was to evaluate the attitude at our institution in using chemotherapy at the end of life in oncology patients. We compared our habits with other clinical patterns in medical oncology, calculating the temporal interval between the last chemotherapy administration and death of th…

Understanding the redistribution of soil organic carbon (OC) driven by erosion contributes to the global carbon budget and watershed management. Quantifying the sources of eroded OC in sediments provides new insights to addressing this issue. However, limited quantitative information on the factors influencing OC sourc…

BACKGROUND: Publications may be a modifiable factor toward research project grant (RPG) funding decisions, the objective was to determine the association of publication record with later RPG receipt. METHODS: This was a retrospective cohort study of recipients of K01, K08, or K23 US career development awards (CDAs) st…

BACKGROUND: The accelerated loss of muscle strength and mass observed in older type 2 diabetes mellitus (T2DM) patients due to the combined effects of diabetes and obesity, greatly increases their risk for sarcopenia. Early detection and treatment of probable and confirmed sarcopenia is paramount to delay mobility disa…

In the last years, the need for new efficient video compression methods grown rapidly as frame resolution has increased dramatically. The Joint Collaborative Team on Video Coding (JCT-VC) effort produced in 2013 the H.265/High Efficiency Video Coding (HEVC) standard, which represents the state of the art in video codin…

BACKGROUND: Outbreaks ofpneumonia (PCP) in kidney transplant recipients are frequently reported worldwide. However, the general guidelines propose only short-term prophylaxis with trimethoprim-sulfamethoxazole after kidney transplantation. We experienced 3 PCP outbreaks in the last 10 years despite providing the recomm…

INTRODUCTION: The prevalence of Rheumatoid Arthritis (RA) has been steadily increasing over the last thirty years, particularly among women. Due to the conflicting results of various studies on the link between rheumatoid arthritis and reproductive health, we have undertaken this study to explore their relationship. M…

We report the present day GNSS velocities (2015-2021) and strain rates in Himachal, Kashmir and Ladakh Himalaya covering the rupture zones of the 2005 Muzaffarabad earthquake and the 1905 Kangra earthquake. Geodetic strain rates estimated from GPS velocities of about 58 sites spanning last two decades of measurements i…

Photosynthesis started to evolve some 3.5 billion years ago COis the substrate for photosynthesis and in the past 200-250 years, atmospheric levels have approximately doubled due to human industrial activities. However, this time span is not sufficient for adaptation mechanisms of photosynthesis to be evolutionarily ma…
