PURPOSE: To investigate the blood supply to the nipple areola complex (NAC) on thoracic CT angiograms (CTA) to improve breast pedicle design in reduction mammoplasty. METHODS: In a single centre, CT scans of the thorax were retrospectively reviewed for suitability by a cardiothoracic radiologist. Suitable scans had one or both breasts visible in extended fields, with contrast enhancement of breast vasculature in a female patient. The arterial sources, intercostal space perforated, glandular/subcutaneous course, vessel entry point, and the presence of periareolar anastomoses were recorded for the NAC of each breast...

Wnt signaling is a conserved pathway involved in expansion of neural progenitors and lineage specification during development. However, the role of Wnt signaling in the post-stroke brain has not been well-elucidated. We hypothesized that Wnt-3a would play an important role for neurogenesis and brain repair. Adult male mice were subjected to a focal ischemic stroke targeting the sensorimotor cortex. Mice that received Wnt-3a (2 µg/kg/day, 1 h after stroke and once a day for the next 2 days, intranasal delivery) had reduced infarct volume compared to stroke controls...

REVIEW
Gösta Rutger Persson
The present literature review is focused on two main areas: (i) periodontal conditions in older individuals; and (ii) the scientific data available on periodontal treatment outcomes in individuals ≥ 75 years of age. The population of older people is increasing but the data on periodontal therapies and their efficacy in this population are limited and need to be carefully reviewed. Although life expectancy has increased, this does not mean that older people are medically healthy. Several chronic systemic diseases are associated with periodontitis, and the prevalence of most chronic diseases increases with age...

Influenza vaccine development is considered to be complicated and challenging. Constantly evolving influenza viruses require continuous global monitoring and reformulation of the vaccine strains. Peptide conserved among different strains and subtypes of influenza A virus are well-thought-out to be attractive targets for development of cross protective influenza vaccine based on cellular response. Three highly conserved (> 90%) matrix 1 peptides ILGFVFTLTVPSERGLQRRRF (PM 1), LIRHENRMVLASTTAKA (PM 2) and LQAYQKRMGVQMQR (PM 3) containing multiple T cell epitopes have been assessed for their immunogenic potential in vitro, subjecting peripheral blood mononuclear cells from healthy volunteers to repetitive stimulation of these chemically synthesised peptides and measuring their interferon (IFN)-γ level and proliferation by ELISA (Enzyme-linked immunosorbent assay) and MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide) assay, respectively...

Accelerated data acquisition with simultaneous multi-slice (SMS) imaging for functional MRI studies leads to interacting and opposing effects that influence the sensitivity to blood oxygen level-dependent (BOLD) signal changes. Image signal to noise ratio (SNR) is decreased with higher SMS acceleration factors and shorter repetition times (TR) due to g-factor noise penalties and saturation of longitudinal magnetization. However, the lower image SNR is counteracted by greater statistical power from more samples per unit time and a higher temporal Nyquist frequency that allows for better removal of spurious non-BOLD high frequency signal content...

Sexual dysfunctions are common, but underrecognized, in patients with chronic kidney disease (CKD) and are inversely associated with the glomerular filtration rate (GFR). Sexual dysfunctions may affect quality of life in males with CKD. The aim of this study was to analyze the relationship among sex hormones, sexual function, and sexual satisfaction in a group of men between 18 and 50 years of age with CKD Stages 1 to 5 not treated with hemodialysis or peritoneal dialysis. Fasting blood samples for hemoglobin, testosterone, prolactin, and luteinizing hormone and questionnaire surveys (Sexual Complaints Screener for Men, International Index of Erectile Function, and Aging Male Symptom scale) were evaluated in 100consecutive men...

Deep sternal wound infection is a severe complication after open heart surgery. According to the different severity and dimensions of the deep sternal wound infection, the treatment method is different. In this study, we aimed to describe our experience with the rectus abdominis myocutaneous flap for large sternal wound management, especially when 1 or 2 internal mammary arteries were absent.Between October 2010 and January 2016, a retrospective review of 9 patients who suffered from the extensive thoracic defects after deep sternal wound infection was conducted...

INTRODUCTION    Among all lung tumors non-small cell lung cancer (NSCLC) is the most common. Conventional conservative treatment in medically inoperable patients with early stage NSCLC has a poor outcome. To improve treatment efficacy stereotactic ablative radiotherapy (SABR) has been developed to enable the delivery of high-dose radiation to the tumor.  OBJECTIVES    This prospective study was conducted to confirm the hypothesis that a sudden death of cancer cells after SABR may lead to systemic immune response changes...

Familial exudative vitreoretinopathy (FEVR) is a hereditary eye disease characterized by defects in the development of periphery retinal vessels. However, the clinical phenotypes of FEVR vary widely from asymptomatic to complete blindness. We analyzed patients from three Chinese families and one sporadic patient with FEVR to investigate the clinical features and disease-causing mutations. Ocular phenotypes included increased ramification of the peripheral retinal vessels, a peripheral avascular zone, inferotemporal dragging of the optic disc and macula, and retinal folds...

Lead poisoning of animals due to ingestion of fragments from lead-based ammunition in carcasses and offal of shot wildlife is acknowledged globally and raises great concerns about potential behavioral effects leading to increased mortality risks. Based on analyses of tracking data, we found that even sub-lethal lead concentrations in blood (25 ppb, wet weight), can likely negatively affect movement behavior (flight height and movement rate) of free-ranging scavenging Golden Eagles (Aquila chrysaetos). Lead levels in liver of recovered post-mortem analyzed eagles suggested that sub-lethal exposure increases the risk of mortality in eagles...

Glucose is an important metabolic fuel and circulating levels are tightly regulated in most mammals, but can drop when body fuel reserves become critically low. Glucose is mobilized rapidly from liver and muscle during stress in response to increased circulating cortisol. Blood glucose levels can thus be of value in conservation as an indicator of nutritional status and may be a useful, rapid assessment marker for acute or chronic stress. However, seals show unusual glucose regulation: circulating levels are high and insulin sensitivity is limited...

Signal transducer and activator of transcription 3 (STAT3) is one of the crucial transcription factors in the Janus kinase (JAK)/STAT signaling pathway, and it was previously considered as acute phase response factor. A number of interleukins (ILs) such as IL-5, IL-6, IL-9, IL-10, IL-12, and IL-22 are known to be involved in activation of STAT3. In addition, various growth factors and pathogenic or oxidative stresses mediate the activation of a wide range of functions via STAT3. In this study, a STAT3 homolog was identified and functionally characterized from rock bream (RbSTAT3), Oplegnathus fasciatus...

Exosomes represent an attractive vehicle for the delivery of biomolecules. However, mechanisms for loading functional molecules into exosomes are relatively unexplored. Here we report the use of the evolutionarily conserved late-domain (L-domain) pathway as a mechanism for loading exogenous proteins into exosomes. We demonstrate that labeling of a target protein, Cre recombinase, with a WW tag leads to recognition by the L-domain-containing protein Ndfip1, resulting in ubiquitination and loading into exosomes...

Pathogens and allergens are deemed as two contrasting facets of host immune status, deficiency and exuberant. In silico domain analysis of a diverse panel of pathogen and allergen proteins has revealed the shortcoming of this notion. Both the pathogen and allergen proteins elicit immune activation, with the outcome of immune agitation depending on the pathogen strain, allergen exposure duration, and host factors. Pathogens can replicate within the host and constantly irritate the immune system, leading to blood coagulation, respiratory collapse and death...

BACKGROUND: Laparoscopic distal pancreatectomy (Lap-DP) for benign lesions or those with low malignant potential has been proven safe and effective, and its performance is now widespread [1-3]. Lap-DP for left-sided pancreatic cancer (PC) is also being increasingly performed. According to some reports, Lap-DP has superior short-term outcomes (blood loss, postoperative hospital stay) and comparable oncological outcomes and overall survival with those of open distal pancreatectomy (Op-DP) [4-6]...

BACKGROUND: We developed a modified delta-shaped gastroduodenostomy technique in totally laparoscopic distal gastrectomy. This novel technique, which effectively reduces the required quantity of linear stapler [1-3], was named as self-pulling and latter transected delta-shaped anastomosis (Delta SPLT) [4]. METHODS: Delta SPLT was performed on 15 patients with stage cT1-2 antral cancer. We ligated the duodenum with a rope instead of transecting it and used the ligature rope to pull the duodenum during the whole progress of gastroduodenostomy...

The pronephros is the first kidney type to form in vertebrate embryos. The first step of pronephrogenesis in the zebrafish is the formation of the intermediate mesoderm during gastrulation, which occurs in response to secreted morphogens such as BMPs and Nodals. Patterning of the intermediate mesoderm into proximal and distal cell fates is induced by retinoic acid signaling with downstream transcription factors including wt1a, pax2a, pax8, hnf1b, sim1a, mecom, and irx3b. In the anterior intermediate mesoderm, progenitors of the glomerular blood filter migrate and fuse at the midline and recruit a blood supply...

Granulocyte colony stimulating factor (GCSF) has a key role in the production of neutrophilic granulocytes during normal hematopoietic development and release of neutrophils into the blood circulation. In this study we have identified and characterized two paralogs of GCSF (RbGCSF) in rock bream. Although RbGCSF-1 and RbGCSF-2 share low sequence conservation, its domains and protein structure still share significant similarity. Basal levels of RbGCSF-1 gene expression was high in peripheral blood leukocytes (PBLs), spleen and intestine whereas the RbGCSF-2 was highly expressed in PBLs and kidney, of healthy animals...
