Epigenetic deregulation is increasingly being recognized as a hallmark of cancer. Recent studies have identified many new epigenetic biomarkers, some of which are being introduced into clinical practice for diagnosis, molecular classification, prognosis or prediction of response to therapies. O-6-methylguanine-DNA methyltransferase gene is the most clinically advanced epigenetic biomarker as it predicts the response to temozolomide and carmustine in gliomas. Therefore, epigenomics may represent a novel and promising tool for precision medicine, and in particular, the detection of epigenomic biomarkers in liquid biopsies will be of great interest for monitoring diseases in patients...

BACKGROUND: There has been recent interest in wide awake hand surgery, also referred to as "wide awake local anesthesia with no tourniquet" (WALANT) surgery. Using a model of single trigger finger release (TFR) surgery, a hypothesis was made that WALANT would result in decreased hospital time and cost than patients receiving sedation with monitored anesthetic care (MAC). METHODS: Consecutive cases of single TFR surgery with MAC were compared with WALANT. All surgeries were performed in the same manner, at the same facility, and by the same surgeon...

BACKGROUND: Rock climbing first evolved as a sport in the late 18th century. With its growing popularity, the number of rock climbing-related injuries has potential to increase, spurring a rise in the number of articles associated with it. Despite the available literature, there remains a paucity of information about upper extremity injuries sustained by rock climbers, and no studies to date have focused on gender-specific injuries. METHODS: A 24-question online survey was distributed to rock climbers about upper extremity injuries sustained during rock climbing...

OBJECTIVES: To compare nilotinib concentrations obtained by venous blood sampling and dried blood spot (DBS) in patients with chronic myeloid leukaemia (CML). It was investigated how to predict nilotinib plasma levels on the basis of DBS. METHODS: Forty duplicate DBS and venous blood samples were collected from 20 patients. Capillary blood was obtained by finger prick and spotted on DMPK-C Whatman sampling paper, simultaneously with venous blood sampling. Plasma concentrations were predicted from DBS concentrations using three methods: (1) individual and (2) mean haematocrit correction and (3) the bias between plasma and DBS concentrations...

Many genetically engineered rat strains have been produced for biomedical research. The simple and quick production of knock-out and knock-in rats is currently possible using genome editing techniques incorporating zinc finger nuclease (ZFN), transcription activator-like effector nuclease (TALEN), or clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9. Genome-edited animals have been produced by the introduction of endonucleases into embryos using conventional microinjection and a new electroporation method named Technique for Animal Knockout system by Electroporation (TAKE)...

Zinc-finger nucleases (ZFNs) are programmable nucleases that have opened the door to the genome editing era. The construction of ZFNs recognizing a target sequence of interest is laborious, and has not been widely used recently. However, key ZFN patents are expiring over the next 2-4 years, enabling a wide range of deployments for clinical and industrial applications. This article introduces a ZFN construction protocol that uses bacterial one-hybrid (B1H) selection and single-stranded annealing (SSA) assay.

Heterozygous GATA2 mutations underlie an array of complex hematopoietic and lymphatic diseases. Analysis of the literature reporting three recurrent GATA2 germline (g) mutations (gT354M, gR396Q, gR398W) revealed different phenotype tendencies. While all three mutants differentially predispose to myeloid malignancies, there was no difference in leukemia-free survival for GATA2 patients. Despite intense interest, the molecular pathogenesis of GATA2 mutation is poorly understood. We functionally characterized a GATA2 mutant allelic series representing major disease phenotypes caused by germline and somatic (s) mutations in zinc finger (ZF) 2...

The heat shock response is crucial for organisms against heat-damaged proteins and maintaining homeostasis at a high temperature. Heterologous expression of eukaryotic molecular chaperones protects Escherichia coli from heat stress. Here we report that expression of the plant E3 ligase BnTR1 significantly increases the thermotolerance of E. coli. Different from eukaryotic chaperones, BnTR1 expression induces the accumulation of heat shock factor σ(32) and heat shock proteins. The active site of BnTR1 in E...

BACKGROUND: Dupuytren disease is a chronic nonmalign fibroproliferative disorder that causes finger contractures via proliferation of new tissue under the glabrous skin of the hand, resulting in multiple functional limitations for the patient. As many surgical therapy options exist, patients suffering from this condition actively search for information in their environment before consulting a health professional. OBJECTIVE: As little is known about the quality of Web-based patient information, the aim of this study was to conduct its systematic evaluation using a validated tool...

Grasping and manipulating an object requires us to perceive its material compliance. Compliance is thought to be encoded by relationships of force, displacement and contact area at the finger pad. Prior work suggests that objects must be sufficiently deformed to become discriminable, but the utility of time-dependent cues has not been fully explored. The studies herein find that the availability of force-rate cues improve compliance discriminability so as to require less deformation of stimulus and finger pad...

The electroactive β-phase is most desirable due to its highest piezo-, pyro- and ferro-electric properties in poly(vinylidene fluoride) (PVDF). Induction of β-phase is successfully accomplished in titanium dioxide (TiO2) nanoparticles (NPs) doped spin coated PVDF nanocomposite (PNC) films. The optimized yields of β-phase and homogeneous ultra-smooth free standing PNC film is utilized in mechanical energy harvesting application by fabricating a nanogenerator (NG) where the typical electrical poling step is not undertaken...

Single zinc finger domain containing proteins are very few in number. Of numerous zinc finger proteins in eukaryotes, only three of them like GAGA, Superman and DNA binding by one finger (Dof) have single zinc finger domain. Although few zinc finger proteins have been described in eubacteria, no protein with single C4 zinc finger has been described in details in anyone of them. In this article, we are describing two novel C-terminal C4 zinc finger proteins-Msmeg_0118 and Msmeg_3613 from Mycobacterium smegmatis...

When picking up objects using a pinch grip, there are usually numerous places at which one could place the thumb and index finger. Yet, people seem to consistently place them at or close to the centre of mass (COM), presumably to minimize torque and therefore the required grip force. People also prefer to grasp objects by parallel surfaces and ones with higher friction coefficients (rough surfaces), to prevent the object from slipping when they lift it. Here, we examine the trade-off between friction and COM...

The GATA2 gene codes for a hematopoietic transcription factor that through its two zinc fingers (ZF) can occupy GATA-DNA motifs in a countless number of genes. It is crucial for the proliferation and maintenance of hematopoietic stem cells. During the past 5 years, germline heterozygous mutations in GATA2 were reported in several hundred patients with various phenotypes ranging from mild cytopenia to severe immunodeficiency involving B cells, natural killer cells, CD4(+) cells, monocytes and dendritic cells (MonoMAC/DCML), and myeloid neoplasia...

BACKGROUND: The oil yield trait of oil palm is expected to involve multiple genes, environmental influences and interactions. Many of the underlying mechanisms that contribute to oil yield are still poorly understood. In this study, we used a microarray approach to study the gene expression profiles of mesocarp tissue at different developmental stages, comparing genetically related high- and low- oil yielding palms to identify genes that contributed to the higher oil-yielding palm and might contribute to the wider genetic improvement of oil palm breeding populations...
