Transcriptional control, but not subcellular location, of PGC-1{alpha} is altered following exercise in a hot environment
The purpose of this study was to determine mitochondrial biogenesis-related mRNA expression, binding of transcription factors to the peroxisome proliferator-activated receptor- coactivator 1-α (PGC-1α) promoter, and subcellular location of PGC-1α protein in human skeletal muscle following exercise in a hot environment compared with a room temperature environment. Recreationally trained males (n = 11) completed two trials in a temperature- and humidity-controlled environmental chamber. Each trial consisted of cycling in either a hot (H) or room temperature (C) environment (33 and 20°C, respectively) fo...

Baroreflex regulation affects ventilation in the Cururu toad Rhinella schneideri [RESEARCH ARTICLE]
Lucas A. Zena, Glauber S. F. da Silva, Luciane H. Gargaglioni, and Kenia C. Bicego Anurans regulate short-term oscillations in blood pressure through changes in heart rate (fH), vascular resistance and lymph hearts frequency. Lung ventilation in anurans is linked to blood volume homeostasis by facilitating lymph return to the cardiovascular system. We hypothesized that the arterial baroreflex modulates pulmonary ventilation in the Cururu toad Rhinella schneideri, and that this relationship is temperature-dependent. Pharmacologically induced hypotension (sodium nitroprusside) and hypertension (phenylephrine) increased venti...

Potential Nutrients for Preventing or Treating Bronchopulmonary Dysplasia
Bronchopulmonary dysplasia (BPD) is a frequent complication of extremely preterm infants. Despite recent advances in newborn medicine, the incidence of BPD does not appear to have changed markedly, and specific treatments and prevention strategies are still lacking. Nutrition plays an important role in normal lung development and maturation. Malnutrition may delay somatic growth and new alveoli development, thus aggravating pulmonary injury involved in the pathogenesis of BPD. However, few nutrients have been investigated for their potential to mitigate the pathogenesis of BPD. (Source: Paediatric Respiratory Reviews)

Myelokyphectomy in Spina Bifida: The Modified Fackler/Sagittal Shilla Technique
Severe focal kyphosis occurs in about 10% of infants with myelomeningocele with the apex of the curve centered around the second lumbar vertebra. The kyphosis is fixed in nature and is usually associated with a compensatory thoracic lordosis proximally. Indications for surgery include an impaired sitting balance, recurrent skin ulcerations, respiratory depression, and pain. The Modified Fackler/Sagittal Shilla technique is used to solve these problems in a child nine years of age or younger. It combines aspects of both the Shilla technique described by McCarthy and the originally described Fackler technique for myelokyphos...

Original Research: Metabolic alterations from early life thyroxine replacement therapy in male Ames dwarf mice are transient
Ames dwarf mice are exceptionally long-lived due to a Prop1 loss of function mutation resulting in deficiency of growth hormone, thyroid-stimulating hormone and prolactin. Deficiency in thyroid-stimulating hormone and growth hormone leads to greatly reduced levels of circulating thyroid hormones and insulin-like growth factor 1, as well as a reduction in insulin secretion. Early life growth hormone replacement therapy in Ames dwarf mice significantly shortens their longevity, while early life thyroxine (T4) replacement therapy does not. Possible mechanisms by which early life growth hormone replacement therapy shortens lon...

Original Research: Porcine model for observing changes due to ischemia/reperfusion injury secondary to intra-abdominal endovascular balloon occlusion
Compared with conventional aortic cross-clamping, endovascular balloon occlusion (EBO) is a valuable strategy in unstable ruptured abdominal aorta aneurysm patients; however, it is unclear how long the balloon may remain safely inflated. Using a porcine model, we evaluated the influence of different EBO time periods on intra-abdominal pressure (IAP) and the association between various pathophysiologic indicators and reperfusion time. Twelve healthy three-month-old domestic piglets were subjected to ischemia/reperfusion injury using EBO within the abdominal aorta. Animals were grouped as A, B, and C based on 30, 60, or 120 ...

Evaluating ECG and carboxyhemoglobin changes due to smoking narghile.
CONCLUSION: Although, especially among young people, it is commonly thought that smoking narghile has less harmful or toxic effects than other tobacco products. The results of this study and past studies clearly demonstrated that smoking narghile can cause several ECG changes - including increased QT, P-wave and Tp-Te dispersion - which can be associated with ventricular dysrhythmias.

Generation and Characterization of Eptesicus fuscus (Big brown bat) kidney cell lines immortalized using the Myotis polyomavirus large T-antigen.
Abstract It is speculated that bats are important reservoir hosts for numerous viruses, with 27 viral families reportedly detected in bats. Majority of these viruses have not been isolated and there is little information regarding their biology in bats. Establishing a well-characterized bat cell line supporting the replication of bat-borne viruses would facilitate the analysis of virus-host interactions in an in vitro model. Currently, few bat cell lines have been developed and only Tb1-Lu, derived from Tadarida brasiliensis is commercially available. Here we describe a method to establish and immortalize big brow...

Propagation of damage in the rat brain following sarin exposure: Differential progression of early processes.
Abstract Sarin is an irreversible organophosphate cholinesterase inhibitor and a highly toxic warfare agent. Following the overt, dose-dependent signs (e.g. tremor, hyper secretion, seizures, respiratory depression and eventually death), brain damage is often reported. The goal of the present study was to characterize the early histopathological and biochemical events leading to this damage. Rats were exposed to 1LD50 of sarin (80μg/kg, i.m.). Brains were removed at 1, 2, 6, 24 and 48h and processed for analysis. Results showed that TSPO (translocator protein) mRNA increased at 6h post exposure while TSPO recepto...

Lipoxin A4, a 5-lipoxygenase pathway metabolite, modulates immune response during acute respiratory tularemia.
Abstract Respiratory infection with Francisella tularensis (Ft) is characterized by a muted, acute host response, followed by sepsis-like syndrome that results in death. Infection with Ft establishes a principally anti-inflammatory environment that subverts host-cell death programs to facilitate pathogen replication. Although the role of cytokines has been explored extensively, the role of eicosanoids in tularemia pathogenesis is not fully understood. Given that lipoxin A4 (LXA4) has anti-inflammatory properties, we investigated whether this lipid mediator affects host responses manifested early during infection. ...

The therapeutic potential of differentiated lung cells from embryonic stem cells in lung diseases.
Abstract Lung diseases cause remarkable morbidity and mortality. The choice of effective medical treatment is limited and the number of lung diseases respond to difficultly current treatments. The embryonic stem cells (ESCs), have the potential to differentiate into cell types of all three germinal layers, including lung epithelial cells. So they can be a potential source for new cell therapies for hereditary or acquired diseases of the airways and lungs. Therefore, a method for treatment of lung diseases is cell therapy and use of ESCs that can replace the damaged epithelial and endothelial cells. Progress using ...

Suppressed translation and ULK1 degradation as potential mechanisms of autophagy limitation under prolonged starvation.
Abstract Macroautophagy/autophagy is a well-organized process of intracellular degradation, which is rapidly activated under starvation conditions. Recent data demonstrate a transcriptional upregulation of several autophagy genes as a mechanism that controls autophagy in response to starvation. Here we report that despite the significant upregulation of mRNA of the essential autophagy initiation gene ULK1, its protein level is rapidly reduced under starvation. Although both autophagic and proteasomal systems contribute to the degradation of ULK1, under prolonged nitrogen deprivation, its level was still reduced in...
