Hyperthermia is suspected of accentuating skeletal muscle injury from novel exercise, but this has not been well studied. This study examined if high muscle temperatures alters skeletal muscle injury induced by eccentric exercise (ECC). Eight volunteers (age, 22.5 ± 4.1 year; height, 169.5 ± 10.8 cm; body mass, 76.2 ± 12.6 kg), serving as their own control, and who were not heat acclimatized, c...

Introduction: The CT machine utilizes a bowtie filter to shape the X-ray beam and remove lower energy photons. Configuration of this bowtie filter is complex and its geometry is often not available in detail. It causes the CT dose index (CTDI) be with the different values in measurement versus Monte Carlo simulation studies and other analytical calculations. It is important esp...

Inhibition of DNA replication with hydroxyurea during thymine starvation of Escherichia coli shows that active DNA synthesis is not required for thymineless death (TLD). Hydroxyurea experiments and thymine starvation of lexA3 and uvrA DNA repair mutants rule out unbalanced growth, the SOS response, and nucleotide excision repair as explanations for TLD.

background: nitric oxide (no), a highly reactive radical, participates in the nonspecific natural defense mechanism of the oral cavity. aims and objectives: the present study was attempted to evaluate the salivary no levels in 4–5 year‑old children with early childhood caries (ecc). the objective of the present study was to assess the salivary no concentration in children with different caries ...

BACKGROUND Parasympathetic pulmonary nerves release acetylcholine that induces smooth muscle constriction. Disruption of parasympathetic pulmonary nerves improves lung function and COPD symptoms. AIMS To evaluate 'targeted lung denervation' (TLD), a novel bronchoscopic therapy based on ablation of parasympathetic pulmonary nerves surrounding the main bronchi, as a potential therapy for COPD. ...

BACKGROUND Cytokines play an important role in modulating the muscle's metabolic and immunological responses to exercise. OBJECTIVES In the present study, we investigated changes in the serum levels of Interleukin (IL)-15 as well as tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hs-CRP), as markers of inflammation, in athlete and non-athlete young men following eccentr...

Background: Early childhood caries (ECC) is a severe type of dental caries affecting infants and pre-school children. Because of the infectious nature of the disease, the immunologic response by the host plays an essential role in its development. Objective: This study investigated the association between the presence of salivary sCD14 and ECC. Methods: This study was carried out on 40 healthy ...

BACKGROUND AND AIM: The present study was carried out with the aim to evaluate the salivary glucose levels among children with early childhood caries (ECC) compared to a group of healthy children without any caries and help control ECC.METHODS: 55 children with an age range of 5-6 years were selected from some kindergartens. Then the subjects were divided into two groups of with ECC & without E...
