BACKGROUND: Enhanced recovery pathways (ERPs) have been shown to aid in patient recovery and improve outcomes in many surgical settings. At present, there is limited data available regarding the use and feasibility of ERPs for patients undergoing microsurgical breast reconstruction. We sought to assess patient outcomes before and after the introduction of an ERP that was adopted by multiple surgeons at a single cancer center. METHODS: A multidisciplinary ERP was developed for patients undergoing deep inferior epigastric perforator (DIEP) or muscle-sparing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction...

BACKGROUND: Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning...

BACKGROUND: Modern broiler chickens exhibit very rapid growth and high feed efficiency compared to unselected chicken breeds. The improved production efficiency in modern broiler chickens was achieved by the intensive genetic selection for meat production. This study was designed to investigate the genetic alterations accumulated in modern broiler breeder lines during selective breeding conducted over several decades. METHODS: To identify genes important in determining muscle growth and feed efficiency in broilers, RNA sequencing (RNAseq) was conducted with breast muscle in modern pedigree male (PeM) broilers (n = 6 per group), and with an unselected foundation broiler line (Barred Plymouth Rock; BPR)...

Mammalian protein O-mannosylation comprise a group of post-translational modifications (PTMs) involved in muscle and brain development. Despite the enormous progress made, to date the biological impact of the mammalian O-mannosyl glycoproteome remains largely unknown. Tools are still needed to investigate the structure, role and abundance of O-mannosyl glycans. While O-mannosyl branching has been shown to be of relevance in integrin-dependent cell-migration, and also plays a role in demyelinating diseases, a broader understanding of the biological roles of branched O-mannosyl glycans is lacking in part due to the paucity of detection tools...

Transdifferentiation has been described as a novel method for converting human fibroblasts into induced cardiomyocyte-like cells. Such an approach can produce differentiated cells to study physiology or pathophysiology, examine drug interactions or toxicities, and engineer cardiac tissues. Here we describe the transdifferentiation of human dermal fibroblasts towards the cardiac cell lineage via the induced expression of transcription factors GATA4, TBX5, MEF2C, MYOCD, NKX2-5, and delivery of microRNAs miR-1 and miR-133a...

Iron_sulfur clusters (ISCs) are known to play a major role in various protein functions. Located in the mitochondria, cytosol, endoplasmic reticulum and nucleus, they contribute to various core cellular functions. Until recently, only a few human diseases related to mitochondrial ISC biogenesis defects have been described. Such diseases include Friedreich ataxia, combined oxidative phosphorylation deficiency 19, infantile complex II/III deficiency defect, hereditary myopathy with lactic acidosis and mitochondrial muscle myopathy, lipoic acid biosynthesis defects, multiple mitochondrial dysfunctions syndromes and non ketotic hyperglycinemia due to glutaredoxin 5 gene defect...

BACKGROUND: Scavenger receptor class B type 1 (SR-BI) is the main high-density lipoprotein (HDL) receptor in mammalians. Loss of SR-BI has been proven to disturb HDL metabolism and accelerate atherosclerosis. However, little is known about the plaque features and arterial remodeling in the increased atherogenesis caused by SR-BI deficiency. Here, we explored this issue in atherosclerosis-prone low-density lipoprotein receptor (LDL-R) knockout (KO) mice deficient of SR-BI. METHODS AND RESULTS: SR-BI/LDL-R double KO (dKO) and control LDL-R KO mice were fed an atherogenic diet for 12 weeks...

Development of skeletal muscle is a multistage process that includes lineage commitment of multipotent progenitor cells, differentiation and fusion of myoblasts into multinucleated myofibers, and maturation of myofibers into distinct types. Lineage-specific transcriptional regulation lies at the core of this process, but myogenesis is also regulated by extracellular cues. Some of these cues are initiated by direct cell-cell contact between muscle precursor cells themselves or between muscle precursors and cells of other lineages...

BACKGROUND: Dystroglycan (DG) is an adhesion receptor complex composed of two non-covalently associated subunits, transcribed from a single gene. The extracellular α-DG is highly and heterogeneously glycosylated and binds with high affinity to laminins, and the transmembrane β-DG binds intracellular dystrophin. Multiple cellular functions have been proposed for DG, notwithstanding that its role in skeletal muscle appears central as demonstrated by both primary and secondary severe muscular dystrophic phenotypes collectively known as dystroglycanopathies...

4-hydroxy-2-nonenal (HNE) is a α,β-unsaturated hydroxyalkenal generated by peroxidation of n-6 polyunsaturated fatty acid. This reactive carbonyl compound exhibits a huge number of biological properties that result mainly from the formation of HNE-adducts on free amino groups and thiol groups in proteins. In the vascular system, HNE adduct accumulation progressively leads to cellular dysfunction and tissue damages that are involved in the progression of atherosclerosis and related diseases. HNE contributes to the atherogenicity of oxidized LDL, by forming HNE-apoB adducts that deviate the LDL metabolism to the scavenger receptor pathway of macrophagic cells, and lead to the formation of foam cells...

We report the case of a newborn with arthrogryposis multiplex congenita and severe axial hypotonia without cardiac involvement in which, using a customized targeted next-generation sequencing assay for 64 myopathy-associated genes, we detected a novel homozygous truncating mutation, c.38661_38665del, in exon 197 of the TTN gene that is expressed only in the fetal skeletal isoform. Its pathogenicity is supported by evidence of maternal isodisomy for chromosome 2. Muscle pathology showed fibers with core-like areas devoid of oxidative staining and cytoplasmic bodies...

Recent studies have shown that in addition to being major constituents of the atheromatous core, solid cholesterol crystals (CCs) promote atherosclerotic lesion development and rupture by causing mechanical damage and exerting cytotoxic and pro-inflammatory effects. These findings suggest that targeting CCs might represent a therapeutic strategy for plaque stabilisation. However, little is known about how cholesterol crystallisation is initiated in human atherothrombotic disease. Here, we investigated these mechanisms...

Sexual dimorphism can be achieved using a variety of mechanisms, including sex-specific circuits and sex-specific function of shared circuits, though how these work together to produce sexually dimorphic behaviors require further investigation. Here, we explore how components of the sex-shared defecation circuitry are incorporated into the sex-specific male mating circuitry in Caenorhabditis elegans to produce successful copulation. Using behavioral studies, calcium imaging, and genetic manipulation, we show that aspects of the defecation system are co-opted by the male copulatory circuitry to facilitate intromission and ejaculation...
