BACKGROUND: Sentinel lymph node (SLN) resection is imperative for breast cancer staging. Axillary reverse mapping (ARM) can preserve arm draining nodes and lymphatics during surgery. ARM is generally performed with isosulfan blue (ISB), restricting its use for concurrent SLN biopsy. Indocyanine green (ICG) could serve as an alternative to ISB for ARM procedures. METHODS: SLN mapping and biopsy was performed via periareolar injection of 99 technetium-sulfur colloid (99m TcSc, TSC)...

Archival formalin-fixed paraffin-embedded (FFPE) tissue samples offer a vast but largely untapped resource for genomic research. The primary technical issues limiting use of FFPE samples are RNA yield and quality. In this study, we evaluated methods to demodify RNA highly fragmented and crosslinked by formalin fixation. Primary endpoints were RNA recovery, RNA-sequencing quality metrics, and transcriptional responses to a reference chemical (phenobarbital, PB). Frozen mouse liver samples from control and PB groups (n = 6/group) were divided and preserved for 3 months as follows: frozen (FR); 70% ethanol (OH); 10% buffered formalin for 18 hours followed by ethanol (18F); or 10% buffered formalin (3F)...

The European grapevine moth, Lobesia botrana (Denis & Schiffermüller) (Lepidoptera: Tortricidae), is regarded as the most important insect pest of wine grapes in Europe. If not properly controlled, it can cause significant direct and indirect yield losses due to secondary infections of grape berries by Botrytis cinerea. For these reasons, it is important to preserve the activity of insecticides used against this pest, as the number of insecticidal mode of actions available to control Lepidoptera species on wine grapes in Europe is limited...

Motivation: Single-cell gene expression profiling technologies can map the cell states in a tissue or organism. As these technologies become more common, there is a need for computational tools to explore the data they produce. In particular, visualizing continuous gene expression topologies can be improved, since current tools tend to fragment gene expression continua or capture only limited features of complex population topologies. Results: Force-directed layouts of k-nearest-neighbor graphs can visualize continuous gene expression topologies in a manner that preserves high-dimensional relationships and captures complex population topologies...

OBJECTIVES: Tricuspid valve repair (TVr) has both a theoretical advantage in preserving right ventricular function and disadvantages such as a higher risk of repair failure in the long-term compared with tricuspid valve replacement (TVR). This study was conducted to compare the results of TVr with those of TVR to find an optimal treatment option. METHODS: A literature search of 5 databases was performed. The primary outcome was all-cause mortality. Secondary outcomes were tricuspid reoperation and valve-related events...

Background: Recent evidence suggests that the mineralocorticoid receptor antagonist spironolactone should be the preferred fourth line antihypertensive treatment in resistant hypertension (RHTN). Whether spironolactone improves blood pressure (BP) control in heart failure with preserved ejection fraction (HFpEF) and RHTN is unknown. Methods: We identified patients with RHTN, defined as baseline systolic blood pressure (SBP) between 140 and 160 mmHg on 3 or more medications, in the Americas cohort of the TOPCAT trial, in which patients with HFpEF were randomized to spironolactone vs...

Understanding the effects of global climate disruption on biodiversity is important to future conservation efforts. While taxonomic diversity is widely studied, functional diversity of plants, and recently animals, is receiving increasing attention. Most studies of mammals are short-term, focus on temperate habitats, and rely on traits described in the literature rather than generating traits from observations. Unlike previous studies, this long-term field study assessed the factors driving the functional and taxonomic diversity of small-mammal assemblages in dry tropical forests using both traits recorded from literature and a demographic database...

BACKGROUND/AIMS: Hemodialysis induces an intravascular inflammatory reaction which may further deteriorate renal function. We studied changes of serum interleukin 6 (IL6) and hepatocyte growth factor (HGF) concentrations during dialysis sessions, and at 12 month intervals. The synthesis of these cytokines in arterial endothelial cells in the presence of serum obtained from dialyzed patients was studied. Changes of the inflammatory reaction during 12 months of treatment were correlated with GFR...

Refrigeration alone or in combination with other technologies represents the main tool used in the last decades to preserve the freshness of black truffles. This is principally due to the delicateness and vulnerability of this edible hypogeous fungus, so that other invasive preservation practices cannot be adopted. However, the proliferation of some microbial species during the cold storage still represents an unsolved problem. Pseudomonads are among the main spoiler bacteria responsible for the deterioration of refrigerated black truffles...

Charcot's spine is a long-term complication of spinal cord injury. The lesion is often localized at the caudal end of long fusion constructs and distal to the level of paraplegia. However, cases are rare and the literature relevant to the management of Charcot's arthropathy is limited. This paper reviews the clinical features, diagnosis, and surgical management of post-traumatic spinal neuroarthropathy in the current literature. We present a rare case of adjacent level Charcot's lesion of the lumbar spine in a paraplegic patient, primarily treated for traumatic spinal cord lesion 39 years before current surgery...

Lack of deep understanding of nanoparticles (NPs) actions in oil/water interface set an obstacle to practical applications of Pickering emulsions. Fluorescence labels by incorporation of carbon dots (CDs) into poly(N-isopropylacrylamide) (PNIPAM) matrix can not only mark the action of PNIPAM-based NPs in the interface, but also reflect the colloidal morphologies of PNIPAM. In this work, we employed coaxial electrospraying for fabricating core-shell nanospheres of cellulose acetate encapsulated by PNIPAM and facile incorporation of CDs in PNIPAM shell was achieved simultaneously...

Insulin is a key peptide hormone used for the treatment of both type I and type II diabetes. To maximize the effect of the treatment of these diseases, PEGylation methods for the insulin are widely developed. Here, to make these PEGylation methods most simple, we report the by-product-free intact modification of insulin by cholesterol end-modified poly(ethylene glycol) with urethane, propyl, and methoxy groups, that is, Chol-U-Pr-mPEG. The noncovalent PEGylation by the Chol-U-Pr-mPEG has been achieved by simple mixing of insulin with the Chol-U-Pr-mPEG in aqueous solution, followed by freeze-drying...

Previously, high-resolution three-dimensional imaging of a whole and intact pancreas was not possible, since light is scattered when it passes through cell compartments with different refractive indices. CLARITY is one of the tissue clearing techniques that has yielded success with the central nervous system. To preserve tissue integrity after delipidation, conventional protocols embed tissue in an acrylamide-based hydrogel, which involves the use of specialized equipment. Recently, we determined that the hydrogel-embedding step could be simplified and replaced by passive tissue fixation in 4% paraformaldehyde (PFA)...

This unit outlines a live-cell imaging approach developed for visualization of intracellular calcium flux in human parathyroid tumors following stimulation of the calcium-sensing receptor (CASR), a class C G protein-coupled receptor (GPCR). The primary assay readout, intracellular calcium release induced by activation of the inositol triphosphate receptor, is potentially generalizable to multiple other GPCR signaling events that utilize this common downstream signal transduction pathway. Advantages of the approach include: (1) preservation of native tissue context and positional information, allowing direct visualization of intratumoral functional heterogeneity; (2) quantitative documentation of reactivity to a physiological stimulus in an experimentally tractable ex vivo system; and (3) generation of a dynamic, functional classifier of tumor biochemical behavior to augment static marker assessment...

Grapefruit seed extract (GSE)-containing chitosan-based coating was developed and applied to cherry tomatoes to protect them from Salmonella invasion and improve their storability. The coating colloids were produced by mixing a chitosan colloid (1% [w/w] chitosan) with GSE at various concentrations (0.5%, 0.7%, 1.0%, and 1.2% [w/w]) using high-shear mixing (10000 rpm, 2 min). Coatings with chitosan colloids containing GSE at 0.0%, 0.5%, 0.7%, and 1.0% (w/w) inactivated Salmonella on cherry tomatoes by 1.0 ± 0...
