The mechanism of action of pertuzumab, a recombinant anti-HER2 humanized monoclonal antibody, is complementary to trastuzumab's. On June 8, 2012, the Food and Drug Administration approved the combination of pertuzumab with trastuzumab and docetaxel as first-line treatment of HER2-positive metastatic breast cancer. Furthermore, pertuzumab is the first drug to be approved in the neoadjuvant setting using a pathological complete response as an endpoint. Areas covered: The review provides insights into the main mechanisms of action of pertuzumab...

Super-resolution (SR) has become more vital, because of its capability to generate high-quality ultra-high definition (UHD) high-resolution (HR) images from low-resolution (LR) input images. Conventional SR methods entail high computational complexity, which makes them difficult to be implemented for up-scaling of full-high-definition (FHD) input images into UHD-resolution images. Nevertheless, our previous super-interpolation (SI) method showed a good compromise between PSNR performances and computational complexity...

OBJECTIVE: Single-camera-based gait monitoring is unobtrusive, inexpensive and easy-to-use to monitor daily gait of seniors in their homes. However, most studies require subjects to walk perpendicularly to camera's optical axis or along some specified routes, which limits its application in elderly home monitoring. To build unconstrained monitoring environments, we propose a method to measure step length symmetry ratio (a useful gait parameter representing gait symmetry without significant relationship with age) from unconstrained straight walking using a single camera, without strict restrictions on walking directions or routes...

In the diagnosis of various cancers by analyzing histological images, automatic nuclear segmentation is an important step. However, nuclear segmentation is a difficult problem because of overlapping nuclei, inhomogeneous staining, and presence of noisy pixels and other tissue components. In this paper, we present an automatic technique for nuclear segmentation in skin histological images. The proposed technique first applies a bank of generalized Laplacian of Gaussian (gLoG) kernels to detect nuclear seeds...

BACKGROUND: Newborn screening programs provide testing for all newborns born in this country for conditions that can potentially cause death or disability. Currently each state is responsible for its programs and the number of disorders screened varies from state to state. The current universal recommended metabolic screening panel may include 32 to 58 disorders. Expansion of the programs has impacted the role of nurses in the neonatal intensive care units (NICUs). Nurses are responsible for facilitating the screening process, educating the family, and assisting with follow-up...

Vaginal dryness and associated symptoms may occur in women of any age and are a frequent burden after menopause. The North American Menopause Society recommends long-acting non-hormonal vaginal creams as first-line therapy. A new type of such creams was developed (Remifemin® FeuchtCreme in Austria and Germany). This hormone-free cream contains hamamelis virginiana distillate and well-established vaginal cream ingredients. We explored its physical function and tolerability in an open interventional clinical trial...

Somatostatin analog treatment is first line medical treatment in patients with acromegaly. This drug is currently mainly administered by monthly depot preparations of octreotide and lanreotide. With the innovative transient permeability enhancer, a technology enabling the absorption of drug molecules via transient opening of the tight junctions of the gut epithelium, it is possible to achieve therapeutic octreotide levels after oral ingestion. The present review summarized the preclinical work and the recently reported phase I and III study on oral octreotide capsules in patients with acromegaly...

OBJECTIVE: This in vitro study investigated the marginal fit of metal and zirconia copings before and after veneering on dies with shoulder/chamfer (s/c) finish lines. MATERIALS AND METHODS: Using CAD/CAM, ten (n = 10) each s/c zirconia (NZ) copings and ten (n = 10) each s/c metal (MM) copings were generated. As controls, ten (n = 10) each s/c zirconia copings were copy-milled (ZZ) and ten (n = 10) each s/c metal copings were cast (CC). The vertical marginal discrepancy of the copings was measured at 20 predefined spots of the circular shoulder and chamfer finish lines in microns (μm) before and after a first and a second veneering firing using a stereomicroscope at ×40 magnification...

Intracranial hypotension, especially spontaneous intracranial hypotension (SIH), is a well-recognized entity associated with cerebrospinal fluid (CSF) leaks, and has being recognized better in resent years, while still woefully inadequate. An increasing number of factors including iatrogenic factors are realized to involve in development and progression of intracranial hypotension. The diagnosis remains difficult due to the various clinical manifestations, some of which are nonspecific and easily to be neglected...

INTRODUCTION AND HYPOTHESIS: Anticholinergic medication is the medical treatment for overactive bladder (OAB). These drugs can act on the central nervous system and can lead to cognitive decline, dementia, and potentially death. Patients taking drugs with anticholinergic effects increase their anticholinergic burden-defined as the cumulative effect of taking one or more drugs that can have adverse effects. When prescribing anticholinergic medication for the elderly, we must choose the right drug...

Polymer flooding is an important process in enhanced oil recovery. The displacement front is unstable when low viscosity brine displaces the heavy crude oil in the reservoir. Water-soluble polymers are added to the brine to increase its viscosity which stabilizes the displacement process. To analyze the displacement process at the micro-level, we have investigated the dynamic contact angles in silicone oil-polymer (polyethylene oxide) solution and for the first time. The dynamic contact angle is the apparent contact angle at the three-phase contact line which governs the capillary pressure, and thus is important for the displacement process...

Recombinant protein production coopts the host cell machinery to provide high protein yields of industrial enzymes or biotherapeutics. However, since protein translation is energetically expensive and tightly controlled, it is unclear if highly expressed recombinant genes are translated as efficiently as host genes. Furthermore, it is unclear how the high expression impacts global translation. Here, we present the first genome-wide view of protein translation in an IgG-producing CHO cell line, measured with ribosome profiling...

Crosses between close species can lead to genomic disorders, often considered to be the cause of hybrid incompatibility, one of the initial steps in the speciation process. How these incompatibilities are established and what are their causes remain unclear. To understand the initiation of hybrid incompatibility, we performed reciprocal crosses between two species of Drosophila (D. mojavensis and D. arizonae) that diverged less than 1 Mya. We performed a genome-wide transcriptomic analysis on ovaries from parental lines and on hybrids from reciprocal crosses...

Elevated blood pressure is one of the most significant risk factor for the development of chronic kidney disease (CKD); its treatment is a milestone in CKD management. While it is accepted that a stricter blood pressure control is indicated in patients with proteinuria or microalbuminuria, the exact degree of blood pressure reduction to be obtained in CKD patients is still under debate. Following more recent interpretation of old trials, a BP target for < 140/90 mmHg is suggested for non-proteinuric CKD patients...

Pictures are named more slowly in the context of semantically related pictures than in the context of unrelated pictures. This semantic blocking effect has been studied extensively in adult participants, and one study has revealed its presence in 6-year-old children. However, little is known about the development of the effect with age. In this study, a blocked cyclic naming procedure was arranged for 5- to 7-year-old and 10- to 12-year-old children. The semantic blocking effect obtained did not differ in size between the two age groups...

Osteosarcoma is the most common primary malignant bone tumor in adolescents and young adults. However, the involvement of serine/threonine phosphatase type 5 (PP5) in osteosarcoma remains unclear. The aim of this study was to evaluate the functional role of PP5 in osteosarcoma cells. Firstly, we found that PP5 is widely expressed in several human osteosarcoma cell lines. Then we used lentivirus-delivered siRNA to silence PP5 expression in Saos-2 and U2OS cell lines. Knockdown of endogenous PP5 expression by shRNA-expressing lentivirus significantly decreased the viability and proliferation of the osteosarcoma cells...

The identification of EGFR mutations and their respectively tyrosine kinase inhibitors (TKIs), changed dramatically treatment and survival of patients with EGFR-positive lung cancer. Nowadays, different EGFR TKIs as afatinib, erlotinib and gefitinib are approved worldwide for the treatment of NSCLC harbouring EGFR mutations, in particular exon 19 deletions or exon 21 (Leu858Arg) substitution EGFR mutations. In first-line setting, when comparing with platinum-based chemotherapy, these target drugs improves progression-free survival, response rate and quality of life...
