Myocardial injury in mammals leads to heart failure through pathological cardiac remodelling that includes hypertrophy, fibrosis and ventricular dilatation. Central to this is inability of the mammalian cardiomyocyte to self-renew due to entering a quiescent state after birth. Modulation of the cardiomyocyte cell-cycle after injury is therefore a target mechanism to limit damage and potentiate repair and regeneration. Here we show that cardiomyocyte specific over-expression of the nuclear-matrix associated DNA replication protein, CIZ1, extends their window of proliferation during cardiac development, delaying onset of terminal differentiation without compromising function...

Arkansas is the only U.S. state that does not have a landlord's implied warranty of habitability, meaning tenants have a requirement for maintaining their rental properties at certain habitability standards, but landlords are not legally required to contribute to those minimum health and safety standards. This project assessed the possibility that this lack of landlord responsibility affects tenants' perceived health. Using surveys and interviews, we collected self-reported data on the prevalence and description of problems faced by renters who needed household repairs from their landlords...

Engaging in self-narrative is often touted as a powerful antidote to the bad effects of illness. However, there are various examples of what may broadly be termed "aversion" to illness narrative. I group these into three kinds: aversion to certain types of illness narrative; aversion to illness narrative as a whole; and aversion to illness narrative as an essentially therapeutic endeavor. These aversions can throw into doubt the advantages claimed for the illness narrator, including the key benefits of repair to the damage illness does to identity and life-trajectory...

Cancer stem cells (CSCs) contribute to the relapse and development of new neoplasm lesions. While most available clinical approaches, such as chemical and radiation therapies, will kill the majority of cancer cells, they do not kill them all. Some resisting cells, like CSCs, are able to survive due to their excellent self-maintaining capabilities, even in challenging environments. In the present study, we investigated the mRNA level of DNA repair genes of colon CSCs from the HT29 cell line in response to single-strand damage and double-strand breaks, as well as the evident upregulation of key genes in base excision repair, mismatch repair, non-homologous end-joining, and homologous recombination pathways in these cells...

We report our experience with the urgent treatment of two high-risk patients with infected femoral artery pseudoaneurysms (IFAPs) with the placement of a self-expandable covered stent (SECS). In both cases, there was no perioperative mortality and the aneurysm exclusion was successful without early or late stent thrombosis/stent fracture nor acute or chronic limb ischemia or limb loss. There was no recurrence of local or systemic infection during the follow-up period. Endovascular therapy represents a feasible treatment option for IFAPs in those patients for whom the risk of open surgical repair would be prohibitive, especially under urgent circumstances...

Meiotic recombination is a process that increases genetic diversity and is fundamental for sexual reproduction. Determining by which mechanisms genetic variation is generated and maintained across different phylogenetic groups provides the basis for our understanding of biodiversity and evolution. In this review, we go through different aspects of this essential phenomenon, paying special attention to mammals. We provide a comprehensive view on the organization of meiotic chromosomes and the mechanisms involved in the formation and genomic distribution of recombination hotspots, focusing on the factors influencing the formation and repair of the massive amount of self-induced DNA breaks in early stages of meiosis...

BACKGROUND: Postnatal growth and repair of skeletal muscle relies upon a population of quiescent muscle precursor cells, called satellite cells that can be activated to proliferate and differentiate into new myofibers, as well as self-renew to replenish the satellite cell population. The balance between differentiation and self-renewal is critical to maintain muscle tissue homeostasis, and alterations in this equilibrium can lead to chronic muscle degeneration. The transcription factor CCAAT/enhancer binding protein beta (C/EBPβ) is expressed in Pax7(+) satellite cells of healthy muscle and is downregulated during myoblast differentiation...

BACKGROUND: A wide variety of kidney diseases ultimately lead to tubulointerstitial damage. The initial site of injury is usually the renal tubules, with activation of fibroblasts occurring later. Self-limited disease is characterized by transient cellular activation with timed deactivation and ultimately a return to normal functioning, whereas sustained responses characterize chronic disease and the development of irreversible fibrosis. The underlying molecular and cellular mechanisms of this cascade of events remain an area of active research...

Poly (ADP-ribose) polymerase-1 (PARP1) is a highly conserved enzyme focused on the self-repair of cellular DNA damage. Until now, numbers of PARP inhibitors have been reported and used for breast cancer therapy in recent years, especially in TNBC. However, developing a new type PARP inhibitor with distinctive skeleton is alternatively promising strategy for TNBC therapy. In this study, based on co-crystallization studies and pharmacophore-docking-based virtual screening, we discovered a series of dihydrodibenzo[b,e]-oxepin compounds as PARP1 inhibitors...

We experienced two cases of spontaneous rupture of the urinary bladder associated with radiation cystitis. Case 1 and Case 2 were a 45-year-old female and a 71-year-old female, respectively. Both of them were admitted to our hospital with complaints of high grade fever and severe lower abdominal pain. They had a past history of total hysterectomy followed by radiationtherapy more than10 years ago. The cystography and the subsequent computed tomography revealed spontaneous rupture of the urinary bladder. We performed the operationto repair the perforationsite with omentum covering...

Chronic myeloid leukemia (CML) results from the t(9;22) reciprocal chromosomal translocation producing the BCR-ABL1 gene, conferring growth and proliferation advantages in the CML cells. CML progresses from chronic, often syndrome-free, to blast phase, fatal if not treated. Although the involvement of BCR-ABL1 in some signaling pathways is considered as the cause of CML, the mechanisms resulting in its progression are not completely known. However, BCR-ABL1 stimulates the production of reactive oxygen species (ROS), which levels increase with CML progression and induce BCR-ABL1 self-mutagenesis...

Erosion of peritoneal dialysis (PD) catheters into the intestine is a rare complication of PD. Herein, we convey the first reports of 2 pediatric patients undergoing PD who were found to have the catheter eroding into their intestines. They were treated minimally with catheter removal and antibiotics. Definitive repair of the intestinal injury was not performed. These are the first pediatric patients reported with PD catheter erosion. Perforating injuries may be self-limiting, and therefore a more minimal approach may be considered in certain patient populations who do not express overt signs of peritonitis or illness...

INTRODUCTION: The literature is unanimous in saying that shoulder pain, due to rotator cuff tear (RCT), may be mostly at night; to our knowledge, this statement is not supported by scientific evidence. Our aim was to investigate sleep quality and disturbances in patient with RCT and in a control group. MATERIALS AND METHODS: A case-control design study was used. We enrolled 324 consecutive patients (Group A) (156M-168F, mean age ± SD: 64.94 ± 6.97; range 47-74) who underwent arthroscopic rotator cuff repair...

OBJECTIVE: To demonstrate the use of a modified single-stage technique for the repair of a ventral penile urethral erosion with involvement of the penile skin, as penile urethral erosion is a rare but potential complication of chronic indwelling catheterisation with a lack of available recommendations for reconstructive options. PATIENT AND METHODS: A 44-year-old male with paraplegia, neurogenic bladder dysfunction and chronic sacral decubitus, presented with a large mid-penile erosion of the ventral penile shaft and urethra, which was caused by chronic transurethral indwelling catheterisation while being hospitalised in an intensive care unit...

Computer-assisted surgical (CAS) planning tools are available for craniofacial surgery, but are usually based on computer-aided design (CAD) tools that lack the ability to detect the collision of virtual objects (i.e., fractured bone segments). We developed a CAS system featuring a sense of touch (haptic) that enables surgeons to physically interact with individual, patient-specific anatomy and immerse in a three-dimensional virtual environment. In this study, we evaluated initial user experience with our novel system compared to an existing CAD system...

Jing Lu, Feng-Hou Gao
DNA damage repair is a kind of cellular self-protection mechanism that some relevant proteins are activated when DNA damage response happens in order to maintain the intracellular function stability and structure integrity. Post-translational modifications (PTMs) of proteins can rapidly confers to them more complicated structure and sophisticated function by covalently combining with different small molecules with target proteins, which in turn plays an important regulatory role in DNA damage repair. It was reported that heterogeneous nuclear ribonucleoprotein K (hnRNP K) could be involved in DNA damage repair process under the regulation of its many post-translational modifications, including methylation, ubiquitination, sumoylation and phosphorylation...

Importance: Microglia, the resident immune cells of the central nervous system, play an important role in the brain's response to injury and neurodegenerative processes. It has been proposed that prolonged microglial activation occurs after single and repeated traumatic brain injury, possibly through sports-related concussive and subconcussive injuries. Limited in vivo brain imaging studies months to years after individuals experience a single moderate to severe traumatic brain injury suggest widespread persistent microglial activation, but there has been little study of persistent glial cell activity in brains of athletes with sports-related traumatic brain injury...
