Radiotherapy and neoadjuvant chemotherapy for cervical carcinoma. A randomized multicenter study of sequential cisplatin and 5-fluorouracil and radiotherapy in advanced cervical carcinoma stage 3B and 4A

BACKGROUND: The locoregional failure rate remains high in advanced cervical carcinoma. Chemotherapy (CT) was added to radiotherapy (RT) in order to increase disease control and to improve 5-year survival.METHODS: CT + RT included cisplatin administered 100mg/m2, d.1 plus 5-fluorouracil 1000 mg/m2 D.1 to 5, ci (120 hrs), q every 3rd week for 3 cycles, followed by RT. RT included external beam irrad

THz time-domain reflection spectroscopy of KTiOPO4

Terahertz (THz) radiation has been of increasing interest in the last decades, for security, manufacturing, quality control, medical and security imaging applications. The field requires more efficient and affordable sources and nonlinear upconversion schemes point in this direction. KTiOPO, (KTP) is a well-established material for nonlinear optical applications in the visible and near-IR region t

Effect of atrium geometry and reflectance on daylighting in adjacent rooms

Atria are implemented in buildings to increase daylight, foster interaction and provide ventilation. However, their implementation can be complex if good daylight is to be achieved. This research proposed an investigation about the atrium parameters that affect daylight conditions in a case study. This evaluation concentrated in the atrium geometry and the wall reflectance values. Overall, the out

Test–retest repeatability of [18F]Flortaucipir PET in Alzheimer’s disease and cognitively normal individuals

The aim of this study was to investigate the test–retest (TRT) repeatability of various parametric quantification methods for [18F]Flortaucipir positron emission tomography (PET). We included eight subjects with dementia or mild cognitive impairment due to Alzheimer’s disease and six cognitively normal subjects. All underwent two 130-min dynamic [18F]Flortaucipir PET scans within 3 ± 1 weeks. Data

Lentiviral-mediated gene transfer into haematopoietic stem cells

OBJECTIVES: Lentiviral vectors can transduce nondividing cells. As most haematopoietic stem cells (HSCs) are nondividing in vivo, lentiviral vectors are promising viral vectors to transfer genes into HSCs.DESIGN AND SETTING: We have used HIV-1 based lentiviral vectors containing the green fluorescent protein (GFP) gene to transduce umbilical cord blood CD34+ and CD34+/CD38- cells prior to transpla

Teaching and learning for critical thinking within interdisciplinary fields

Critical thinking is an important aim of higher education, and it is a skill particularly important in interdisciplinary fields. I am proposing a seminar where, based on an initial text and some central discussion questions, we can discuss our experiences with teaching and learning in an interdisciplinary manner. The experience from sustainability-related teaching shows that addressing interdiscip

Survey of non-resuscitation fluids administered during septic shock : a multicenter prospective observational study

BACKGROUND: The indication, composition and timing of administration of non-resuscitation fluid in septic shock have so far received little attention and accordingly the potential to reduce this source of fluid is unknown. The objective of the study was to quantify and characterize non-resuscitation fluid administered to patients with septic shock.METHODS: This prospective observational study was

A latent core of dark traits explains individual differences in peacekeepers’ unethical attitudes and conduct

The influence of military members’ malevolent personality traits on their ethical attitudes and behaviors has been the subject of research for decades. We investigated the relationship between malevolent individual difference factors (Machiavellianism, narcissism, psychopathy, the dominance facet of social dominance orientation, and right-wing authoritarianism) and aspects of military ethics befor

Pressure-driven release of viral genome into a host nucleus is a mechanism leading to herpes infection

Many viruses previously have been shown to have pressurized genomes inside their viral protein shell, termed the capsid. This pressure results from the tight confinement of negatively charged viral nucleic acids inside the capsid. However, the relevance of capsid pressure to viral infection has not been demonstrated. In this work, we show that the internal DNA pressure of tens of atmospheres insid

Raptor vision

Diurnal raptors (birds of the orders Accipitriformes and Falconiformes), renowned for their extraordinarily sharp eyesight, have fascinated humans for centuries. The high visual acuity in some raptor species is possible due to their large eyes, both in relative and absolute terms, and a high density of cone photoreceptors. Some large raptors, such as wedge-tailed eagles and the Old World vultures,

Realizability and internal model control on networks

It is proved that network realizability of controllers can be enforced without conservatism using convex constraints on the closed loop transfer function. Once a network realizable closed loop transfer matrix has been found, a corresponding controller can be implemented using a network structured version of Internal Model Control.

Atmospheric CO2-detection via scheimpflug DIAL employing a simple fiber amplifier

The ever-increasing worldwide environmental awareness has prompted much effort to minimize humanity's ecological footprint. This has led to increased demands for reliable technologies for assessing the current situation as well as the efficiency of new policies and interventions. In particular, CO2-monitoring has attracted lots of attention as CO2 is the greenhouse gas that is emitted in the large

Effects of a dynamic injection flow rate on slug generation in a cross-junction square microchannel

The injection flow rates of two liquid phases play a decisive role in the slug generation of the liquid-liquid slug flow. However, most injection flow rates so far have been constant. In order to investigate the effects of dynamic injection flow rates on the slug generation, including the slug size, separation distance and slug generation cycle time, a transient numerical model of a cross-junction
