The ideal construct for a rotator cuff repair continues to be a hot topic for debate and biomechanical investigation. A recent study shows that anchors could be placed as close as 1 mm apart without impact on pullout strength. However, further overlap (the buddy anchor construct) led to earlier failure. This conclusion differs from other studies that have recommended the "buddy anchor" construct as a bail-out option in osteoporotic bone. Biomechanical studies are an important source of information for surgical decision making, but often do not directly predict the in vivo environment...

This study aimed to determine whether consecutive ovarian stimulation in follicular and luteal phases within a single menstrual cycle (dual stimulation) is achievable and superior to conventional stimulation for poor ovarian responders (PORs). Data of 260 PORs were retrospectively collected and divided into three groups. Group A comprised of cycles with dual ovarian stimulation (n = 76), which were divided into two subgroups (follicular [group A-F] and luteal phase stimulation [group A-L]); group B comprised of cycles with ovarian stimulation that was performed only in the luteal phase (n = 52)...

Hepatoblastoma (HBL) is the most common pediatric liver cancer. In this malignant neoplasm, beta-catenin protein accumulates and increases Wnt signaling due to recurrent activating mutations in the catenin-beta 1 (CTNNB1) gene. Therefore, beta-catenin is a key therapeutic target in HBL. However, controlling beta-catenin production with therapeutic molecules has been challenging. New biological studies could provide alternative therapeutic solutions for the treatment of HBL, especially for advanced tumors and metastatic disease...

Implanting a self-expandable stent at the ostium of the common iliac artery (CIA) may lead to coverage of the orifice of the contralateral CIA. Here, we describe a novel application of the culotte stent technique using a balloon-expandable stent to bail out an ostial stenotic legion of a jailed CIA due to prior self-expandable stent placement. The bilateral CIAs were revascularized by culotte stenting, and patency of the stents was confirmed 3 years after the procedure. The culotte stent technique was successfully applied to an ostial stenotic lesion of a jailed CIA...

BACKGROUND: In the era of dual antiplatelet therapy of aspirin and clopidogrel and systematic stent implantation, glycoprotein IIb/IIIa inhibitors (GPI), including abciximab, eptifibatide and tirofiban, proved beneficial in improving early outcome of percutaneous coronary intervention (PCI), especially in higher risk clinical and/or anatomical subsets. This was associated however, with an increased incidence of bleeding complications. OBJECTIVE: To review whether the established results of GPI in PCI are maintained in the contemporary era of more effective antiplatelet agents (i...

It has been recently reported that the unit cell of wire media metamaterials can be tailored locally to shape the flow of electromagnetic waves at deep-subwavelength scales [Nat. Phys.9, 55 (2013)NPAHAX1745-247310.1038/nphys2480]. However, such bulk structures have a thickness of at least the order of wavelength, thus hindering their applications in the on-chip compact plasmonic integrated circuits. Here, based upon a Sievenpiper "mushroom" array [IEEE Trans. Microwave Theory Tech.47, 2059 (1999)IETMAB0018-948010...

The distributed finite-time formation tracking control problem for multiple unmanned helicopters is investigated in this paper. The control object is to maintain the positions of follower helicopters in formation with external interferences. The helicopter model is divided into a second order outer-loop subsystem and a second order inner-loop subsystem based on multiple-time scale features. Using radial basis function neural network (RBFNN) technique, we first propose a novel finite-time multivariable neural network disturbance observer (FMNNDO) to estimate the external disturbance and model uncertainty, where the neural network (NN) approximation errors can be dynamically compensated by adaptive law...

BACKGROUND: Automatic extracting protein entity interaction information from biomedical literature can help to build protein relation network and design new drugs. There are more than 20 million literature abstracts included in MEDLINE, which is the most authoritative textual database in the field of biomedicine, and follow an exponential growth over time. This frantic expansion of the biomedical literature can often be difficult to absorb or manually analyze. Thus efficient and automated search engines are necessary to efficiently explore the biomedical literature using text mining techniques...

Objectives: Diabetes mellitus, a carbohydrate metabolic disorder, occurs due to absolute or relative deficiency of insulin. Current treatment strategies involve either preventing or delaying the intestinal absorption of glucose to lower the levels of postprandial hyperglycemia (PPHG). Herbal remedies have been since ancient times for treating diabetes mellitus. Therefore, identifying novel phytocompounds with α-amylase and α-glucosidase inhibitory activity that would reduce the glucose absorption as well as the rise in postprandial blood glucose level is vital...

In citrus processing industries, where up to 60% of the whole fruit is discarded, generates citrus waste (peel, seeds, membrane, and pulp) on a massive scale. The waste does not currently have high-value applications, instead the majority is disposed of or pelletized for animal feed. Therefore, a concise and efficacious protocol for processing of Kinnow mandarin (Citrus reticulata) fruit waste to numerous novel Brønsted acidic ionic liquids (3a-k) have been developed. BAILs were characterized using spectroscopic techniques (FT-IR and NMR)...

Chitosan (CS) shows in vitro and in vivo efficacy for siRNA delivery, but with contradictory findings for incompletely characterized systems. To understand which parameters produce effective delivery, a library of precisely characterized chitosans was produced at different DDAs and Mn. Encapsulation and transfection efficiencies were characterized in vitro. Formulations were selected to examine the influence of Mn and N:P ratio on nanoparticle uptake, metabolic activity, genotoxicity, and in vitro transfection...

Mismatch repair-deficient colorectal cancers (CRC) are good responders to anti-programmed cell death ligand-1 (PD-L1) immunotherapy, but the value of PD-L1 testing remains unclear. We studied PD-L1 expression and the tumor immune microenvironment in mismatch repair-deficient (dMMR) CRC as a model of good responders to immunotherapy. We examined 35 dMMR and 34 mismatch repair-proficient (pMMR) CRC using immune cell markers (CD3, CD4, CD8, CD20, CD68, and FOXP3) as well as PD-1 and PD-L1 immunohistochemistry staining in whole tumor specimens and tissue microarray slides to compare 4r PD-L1 immunohistochemistry clones (SP142, E1L3N, 22C3, and 28...
