Docetaxel has demonstrated extraordinary anticancer effects on lung cancer. However, lack of optimal bioavailability due to poor solubility and high toxicity at its therapeutic dose has hampered the clinical use of this anticancer drug. Development of nanoemulsion formulation along with biocompatible excipients aimed for pulmonary delivery is a potential strategy to deliver this poorly aqueous soluble drug with improved bioavailability and biocompatibility. In this work, screening and selection of pharmaceutically acceptable excipients at their minimal optimal concentration have been conducted...

BACKGROUND: Total hip arthroplasty (THA) is a successful procedure to treat end-stage hip osteoarthritis. The procedure is increasingly performed in adults of working age, who often wish to return to sports (RTS) and return to work (RTW). However, a systematic overview of the evidence on RTS and RTW after THA is lacking. OBJECTIVES: Our aim was to systematically review (1) the extent to which patients RTS and RTW after THA, including (2) the time to RTS and RTW...

Siqiu Guo, Tao Zhang, Yulong Song, Feng Qian
This paper presents a particle swarm tracking algorithm with improved inertia weight based on color features. The weighted color histogram is used as the target feature to reduce the contribution of target edge pixels in the target feature, which makes the algorithm insensitive to the target non-rigid deformation, scale variation, and rotation. Meanwhile, the influence of partial obstruction on the description of target features is reduced. The particle swarm optimization algorithm can complete the multi-peak search, which can cope well with the object occlusion tracking problem...

BACKGROUND: The contrast between memory versus executive function impairments is commonly used to differentiate between neurocognitive disorders (NCDs) due to Alzheimer's disease (AD) and vascular cognitive impairment (VCI). We reconsidered this question because of the current use of AD biomarkers and the recent revision of the criteria for AD, VCI, and dysexecutive syndrome. OBJECTIVE: To establish and compare the neuropsychological profiles in AD (i.e., with positive CSF biomarkers) and in VCI...

Vendela Berglund, Gustav Mattsson, Peter Magnusson
Aortic stenosis is the most common valvular heart disease and the prevalence increases with age. Common symptoms include dyspnea, angina, and syncope. Echocardiography is a cornerstone in diagnosis of aortic stenosis. Severe aortic stenosis is defined as peak aortic jet velocity ≥4 m/s, a mean transvalvular gradient ≥40 mmHg, and/or an aortic valve area <1.0 cm2. The two-year mortality in patients with symptomatic aortic stenosis is 50 percent without intervention. The only efficient treatment is intervention, either open heart valve replacement or percutaneous transcatheter implantation of an aortic valve prosthesis (TAVI), which both provide symptomatic relief and improved survival...

The main function of the microcirculatory bed consists in maintaining tissue homeostasis at an optimal level irrespective of the effect of various external and internal factors. Of all types of metabolism (diffusive, filtration-reabsorption and vesicular), directly dependent on the haemodynamic parameters is filtration-reabsorption metabolism which provides exchange of water, low-molecular-weight and water-soluble substances at the opposite to the heart «pole» of the cardiovascular system. The present study was aimed at testing a hypothesis that activation of metabolic processes in man would be accompanied by alterations in haemodynamic parameters which may be registered by means of modern non-invasive methods of examination, i...

Nascent medical students' first view into medical school orients them toward what is considered important in medicine. Based on ethnography conducted over 18 months at a New England medical school, this article explores themes which emerged during a first-year student orientation and examines how these scripts resurface across a four-year curriculum, revealing dynamics of enculturation into an institution and the broader profession. We analyze orientation activities as discursive and embodied fields which serve "practical" purposes of making new social geographies familiar, but which also frame institutional values surrounding "soft" aspects of medicine: professionalism; dynamics of hierarchy and vulnerability; and social difference...

Mathias Schütz
This article presents a hitherto unknown memorandum authored by Kurt Gerstein, the Confessing Church's resistance fighter and witness to the Holocaust. In this memorandum, submitted to the Reich Ministry of the Interior in April 1938, Gerstein deals extensively with the contemporary system of anatomical body procurement, its roots and predicaments. Putting the memorandum into the wider context of his discordant life allows a gap to be closed in Gerstein's biography, whereby his relationship with medicine presented a means of moral reorientation between a Christian requirement and the National Socialist reality...
