BACKGROUND: Although standard fixation of proximal interphalangeal (PIP) arthrodesis by K-wire is relatively inexpensive and well established, it does have some drawbacks, making newer fixation devices interesting. The aim of this study was to clinically and radiologically assess the operative correction of the lesser toe deformation in the form of a PIP arthrodesis using a bioabsorbable 2.7-mm fixation screw. METHODS: From January 2011 until October 2013, 34 patients underwent a PIP arthrodesis using the TRIM-IT (Arthrex) 2...

Strategies to resolve replication blocks are critical for the maintenance of genome stability. Among the factors implicated in the replication stress response is the ATP-dependent endonuclease ZRANB3. Here, we present the structure of the ZRANB3 HNH (His-Asn-His) endonuclease domain and provide a detailed analysis of its activity. We further define PCNA as a key regulator of ZRANB3 function, which recruits ZRANB3 to stalled replication forks and stimulates its endonuclease activity. Finally, we present the co-crystal structures of PCNA with two specific motifs in ZRANB3: the PIP box and the APIM motif...

BACKGROUND: Potentially Inappropriate Prescriptions (PIPs) are a common cause of morbidity, particularly in the elderly. OBJECTIVE: We sought to understand how the Screening Tool of Older People's Prescriptions (STOPP) prescribing criteria, implemented in a routinely used primary care Electronic Medical Record (EMR), could impact PIP rates in community (non-academic) primary care practices. METHODS: We conducted a mixed-method, pragmatic, cluster, randomized control trial in research naïve primary care practices...

An estimated 1-3% of all women in the Netherlands carry breast implants. Since the introduction five decades ago, problems with a variety of breast implants have emerged with direct consequences for the patients' health. Plastic surgeons worldwide reacted through campaigning for auditing on long-term implant quality, surgeon performance, and institutional outcomes in implant registries. Especially, the PIP implant scandal of 2010 demonstrated the paucity of epidemiological data and uncovered a weakness in our ability to even 'track and trace' patients...

BACKGROUND AND PURPOSE: Ca(2+) -activated Cl(-) channels (CaCCs) are gated open by a rise in intracellular Ca(2+) concentration ([Ca(2+) ]i ), typically provoked by Gq -protein coupled receptor activation (Gq PCR). Gq PCR activation initiates depletion of plasmalemmal phosphatidylinositol 4,5-bisphosphate (PIP2 ). Here we ask whether PIP2 acts as a signalling lipid for CaCCs coded by the TMEM16A and TMEM16B genes. EXPERIMENTAL APPROACH: Patch-clamp electrophysiology, in conjunction with genetically-encoded systems to control cellular PIP2 content, was used to define the mechanism of action of PIP2 on TMEM16A and TMEM16B channels...

Synthetic ligands capable of recognizing the specific DNA sequences inside human mitochondria and modulating gene transcription is of increasing demand because of the surge in evidence linking mitochondrial genome and diseases. Herein, we created a new type of mitochondria-specific synthetic ligand, termed MITO-PIPs by conjugating a mitochondria-penetrating peptide with pyrrole-imidazole polyamides (PIPs). The designed MITO-PIPs showed specific localization inside mitochondria in HeLa cells and recognized the target DNA in a sequence-specific manner...

Until the late 1980s, proximal interphalangeal (PIP) joint reconstruction had been almost exclusively performed by the use of monobloc silicone spacers and associated with acceptable to good clinical outcomes.More recently, new materials such as metal-on-polyethylene and pyrocarbon implants were proposed, associated with good short-term and mid-term results.Pyrocarbon is a biologically inert and biocompatible material with a low tendency to wear. PIP pyrolytic implants are characterised by a graphite core, visible on radiographs and covered by a radiolucent outer layer of pyrocarbon...

Stimulus predictability can lead to substantial modulations of brain activity, such as shifts in sustained magnetic field amplitude, measured with magnetoencephalography. Here, we provide a mechanistic explanation of these effects using MEG data acquired from healthy human volunteers (N=13, 7 female). In a source-level analysis of induced responses, we established the effects of orthogonal predictability manipulations of rapid tone-pip sequences (namely, sequence regularity and alphabet size) along the auditory processing stream...

BACKGROUND: Collagenase clostridium histolyticum (CCH) injection is an alternative to surgery for patients with Dupuytren disease (DD) of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints. The success of surgical and nonsurgical treatment modalities for DD is reported to vary widely between 25% and 80% (J Bone Joint Surg Am. 1985;67:1439-1443; Plast Reconstr Surg. 2007;120:44e-54e; J Bone Joint Surg Am. 2007;89:189-198; J Hand Surg Am. 2011:36:936-942; J Hand Surg Am...

BACKGROUND: Aquaporins (AQPs) are known to facilitate water transport across cell membranes, but the role of a single AQP in regulating plant water transport, particularly in plants other than Arabidopsis remains largely unexplored. In the present study, a virus-induced gene silencing (VIGS) technique was employed to suppress the expression of a specific plasma membrane aquaporin PsPIP2;1 of Pea plants (Pisum sativum), and subsequent effects of the gene suppression on root hydraulic conductivity (Lpr), leaf hydraulic conductivity (K leaf ), root cell hydraulic conductivity (Lprc), and leaf cell hydraulic conductivity (Lplc) were investigated, using hydroponically grown Pea plants...

BACKGROUND: Chronic musculoskeletal disorders are a prevalent and costly global health issue. A new form of exercise therapy focused on loading and resistance programmes that temporarily aggravates a patient's pain has been proposed. The object of this review was to compare the effect of exercises where pain is allowed/encouraged compared with non-painful exercises on pain, function or disability in patients with chronic musculoskeletal pain within randomised controlled trials. METHODS: Two authors independently selected studies and appraised risk of bias...

Exercise-based therapy may improve health status for people with Mild Cognitive Impairment (MCI) or dementia but cannot work without adherence, which has proven difficult. This review aimed to evaluate strategies to support adherence among people with MCI or Dementia and was completed in Nottingham/UK in 2017. A narrative synthesis was used to investigate the effectiveness or usefulness of adherence support strategies. Fifteen adherence support strategies were used including theoretical underpinning (programmes based on behavior change theories), individual tailoring, worksheets and exercise booklets, goal setting, phone calls or reminders, newsletters, support to overcome exercise barriers, information, adaptation periods, individual supervision, support for clinicians, group setting, music, accelerometers/pedometers and emphasis on enjoyable activities...

Phosphatidylinositol phosphate (PIP) synthetase is a promising target for the development of new anti-mycobacterium compounds. We previously reported that myo-inositol 1-methylenephosphonate showed inhibitory activity against PIP synthetase. Herein, we report the synthesis of unprotected myo-inositol 4-methylenephosphonate, a constitutional isomer of myo-inositol 1-methylenephosphonate and found that the stereoselective hydrogenation of vinylphosphonate proceeded via Rh catalysis.

The microbial dysbiosis associated with necrotizing enterocolitis (NEC) in preterm infants suggests that early exposure to probiotics may decrease and antibiotics may increase NEC risk. However, administration of Bifidobacterium breve strain BBG-001 to preterm infants did not affect NEC incidence in a multicenter randomised controlled phase 3 trial (PiPS trial). Using a subset of these subjects we compared the fecal microbiome of probiotic and placebo groups and assessed the impact of early antibiotic treatment...

This study investigated the network of genes that are co-expressed with androgen receptor (AR) to discover novel AR targets in breast cancer. Bioinformatics analysis of two datasets from breast cancer cell lines resulted in the identification of an AR-gene signature constituted of 98 genes that highly correlated with AR expression. Notably, C1orf64 showed the highest positive correlation with AR across the datasets with a correlation coefficient (CC) of 0.737. In addition, C1orf64 closely correlated with AR expression in primary and metastatic breast tumors and C1orf64 expression was relatively higher in breast tumors with a lower grade and lobular histology...

BACKGROUND: The region between the proximal interphalangeal (PIP) and the metacarpophalangeal (MP) creases has greater laxity than other regions in the fingers, allowing for primary closure of the donor site. We postulated if we could consistently locate perforators from the region between the PIP and the MP crease on the radial side of the middle and ring fingers, on which a scar would be less conspicuous than one on the radial side of the index finger, these regions would be ideal donor sites for digital reconstruction using very small flaps...
