Objective: The aim of this study is to determine the outcome of trastuzumab therapy for 6 or 12 months in patients with HER2 positive operable breast cancer who followed the national health insurance system in Indonesia. Methods: Data were extracted from medical records of Dr. M Djamil General Hospital Padang and Dharmais Cancer Hospital/ National Cancer Center Jakarta for post-operative breast HE...

Background: Breast cancer is the most common cancer in women. Monthly breast self-examination (BSE) has been presented as one of the best screening methods available. The aim of this study was to compare effects of both direct and indirect methods of teaching of BSE on knowledge and attitudes of nursing and midwifery personnel. Materials and Methods: The present study was performed on 89 nursing a...

Breast cancer among women occupies a leading position in the profile of cancer incidence in most parts of the world. The present study of the incidence and prevalence of breast cancer was carried out using data from the Chelyabinsk population cancer registry for 2006-2015. A stable growth trend in the incidence over time was noted overall, as well as major differences in the figures for women of d...

Background: ETV6/RUNX1 gene fusion is the most frequently seen chromosomal abnormality in childhood acute lymphobastic leukamia (ALL). However, additional genetic changes are known to be required for the development of this type of leukaemia. Therefore, we here aimed to assess the somatic mutational profile of four ALL cases carrying the ETV6/RUNX1 fusion gene using whole-exome sequencing. Methods...

Mitral paravalvular leak (PVL) recurrence after surgical correction has not yet been well demonstrated. The aims of this study were (1) to evaluate the long-term results of surgical mitral PVL correction, including recurrent PVL, and (2) to elucidate the factors including surgical technique that affect the risk of recurrent PVL.

The Begraft Peripheral PMCF study is a prospective, non-randomized study, conducted at the vascular departments of 4 hospitals in Belgium. This manuscript reports the findings up to 12-month follow-up time for the total cohort. The primary endpoint of the study is primary patency at 12 months. Primary patency is defined as a target lesion without a hemodynamically significant stenosis on duplex ul...

To evaluate the safety and efficacy of a novel balloon-expandable stentgraft for endovascular treatment of visceral artery aneurysms (VAA).

The chimney technique has been developed for the treatment of complex aortic aneurysms. We analyzed the midterm to long-term outcomes of this approach from a single- centre experience.

To evaluate durability of Mitroflow and patterns of use compared with other aortic valves we performed a systematic review of the literature.

Experimental evidence suggests that blood cardioplegia (BCP) may be superior to cold crystalloid cardioplegia (CCP) for myocardial protection. However, robust clinical data are lacking. We compared post-operative outcome of patients undergoing aortic valve replacement (AVR) using cold anterograde-retrograde intermittent BCP versus anterograde (CCP).

The number of citations that an article has received reflects its impact on a particular research area.

Oxidative stress has a key role in pathophysiology of type 2 diabetes mellitus (T2DM) and its complications as a most common health problem. Due to controversial evidence regarding the association between antioxidants' gene varients and T2DM, our aim was a systematic review of the current meta-analyses.

Insular gliomas are heterogeneous lesions whose management presents multiple challenges for their tendency to affect young patients in good neurological and cognitive conditions, their deep anatomic location and proximity with critical functional and vascular structures. The appropriate management of insular gliomas requires a multidisciplinary evidence-centred teamwork grounded on the best anatom...

In comparison to other tumors, various barriers such as the blood-brain barrier (BBB), enzymatic barriers and the blood-brain tumor barrier (BBTB) severely impede the successful treatment of glioma. Peptide ligands were frequently used as targeting moieties to mediate brain tumor targeted drug delivery. LWSW (SYPGWSW) is a recently reported quorum sensing peptide which is able to efficiently cross...

Isolating subpopulations of heterogeneous cancer cells is an important capability for the meaningful characterization of circulating tumor cells at different stages of tumor progression and during epithelial to mesenchymal transition (EMT). Here, we describe a two-dimensional separation approach that yields phenotypically-distinct subpopulations of cancer cells. Magnetic nanoparticles coated with ...

Magnetic fluids (e.g., paramagnetic solutions and ferrofluids) have been increasingly used for label-free separation of non-magnetic particles in microfluidic devices. Their biocompatibility, however, becomes a concern in high-throughput or large-volume applications. One way to potentially resolve this issue is re-suspending the particles that are separated in a magnetic fluid immediately into a b...

A major challenge in transistor technology scaling is the formation of controlled ultra-shallow junctions with nanometer-scale thickness and high spatial uniformity. Monolayer doping (MLD) is an efficient method to form such nanoscale junctions, where the self-limiting nature of semiconductor surfaces is utilized to form adsorbed monolayers of dopant-containing molecules followed by rapid thermal ...

Two important goals in orthopedic implants research are to promote osseointegration and prevent infection. However, much of previous efforts have been paid on the design of coatings either to enhance osseointegration while ignoring antibacterial activity or vice versa, to prevent infection while ignoring bone integration. Here, we designed a multifunctional mineralized collagen coating on titanium...

Streptococcus pneumoniae (SP) is a pathogenic bacterium and a major cause of community-acquired pneumonia that could be fatal if left untreated. Therefore, rapid and sensitive detection of SP is crucial to enable targeted treatment during SP infections. In this study, DNA tetrahedron (DNA TH) with a hollow structure is anchored on gold electrodes to construct an electrochemical immunosensor for ra...

The dual-phase membrane has received much attention as the solution to the instability of the oxygen permeation membrane. It has been reported that the oxygen flux of the dual-phase membrane is greatly enhanced by the active coating layer. However, there has been little discussion about the enhancement mechanism by surface coating in the dual-phase membrane. This study investigates the oxygen flux...

Antibiotic resistance is one of the greatest current threats to human health, and without significant action we face the chilling prospect of a world without effective antibiotics. Although continued effort toward the development of new antibiotics, particularly those with novel mechanisms of action, remains crucial, this alone probably will not be enough to prevail, and it is imperative that addi...

RNA-RNA assembly governs key biological processes and is a powerful tool for engineering synthetic genetic circuits. Characterizing RNA assembly in living cells often involves monitoring fluorescent reporter proteins, which are at best indirect measures of underlying RNA-RNA hybridization events and are subject to additional temporal and load constraints associated with translation and activation ...

Understanding virus-host interactions is crucial for vaccine development. This study investigates such interactions using fluorescent nanodiamonds (FNDs) coated with vaccinia envelope proteins as the model system. To achieve this goal, we noncovalently conjugated 100-nm FND with A27(aa 21-84), a recombinant envelope protein of vaccinia virus, for glycosaminoglycans (GAGs)-specific targeting and im...
