Impact microindentation is a new technique for the in vivo measurement of tissue-level properties of cortical bone in humans. To address issues related to the proper application of IMI in clinical practice and to directly examine cortical bone properties in patients with tibia pathology, we studied 11 subjects without tibia pathology and 9 patients with Paget's disease of the tibia in biochemical remission after bisphosphonate treatment. Serial indentations in the tibiae of both legs were performed in all subjects by a single operator until 10 adequate measurements were obtained in each tibia...

Behçet's disease (BD) is a multi-systemic inflammatory disorder characterized by the "triple symptom complex". Several pro-inflammatory cytokines, mainly derived from the immune Th17 axis, seem to be involved in different pathogenic pathways leading to development of the clinical manifestations. Here, we have analyzed the expression and role of IL-26 in active BD patients, an inflammatory disorder characterized by bronchoalveolar lavage fluid (BAL) and in cerebrospinal fluid (CSF) inflammation. On this basis, the primary aim of our work was to study IL-26 levels in serum, BAL CSF) from active BD patients...

PURPOSE: To compare the visual quality of patients with keratoconus who underwent penetrating keratoplasty (PKP) or deep anterior lamellar keratoplasty (DALK) with fluid dissection. DESIGN: Cross-sectional, observational study. METHODS: Twelve eyes that underwent PKP (PKP group) were compared to 24 eyes that underwent DALK (DALK group) after complete removal of sutures and stability of refraction. Visual, refractive, corneal topographic, corneal aberrometry, and ocular aberrometry parameters were compared for both groups...

BACKGROUND: Although hypothyroidism has an insidious onset and relatively asymptomatic, exertional dyspnea and fatigue can be the presenting complaints. OBJECTIVES: The aim is to assess functional lung impairment in hypothyroid patients both at rest and during exercise. METHODS: A case-control study was carried out on 42 patients with newly diagnosed hypothyroidism and 12 control subjects. Hypothyroidism was diagnosed based on high value of thyroid stimulating hormone (TSH) ≥6 μIU/ml, and low value of free thyroxin (FT4) ≤0...

BACKGROUND: Neuropathic pain represents a therapeutic challenge, and treatments with increased efficacy and tolerability still need to be developed. Opiorphin protects endogenous enkephalins from degradation, potentiating enkephalin-dependent analgesia via the activation of opioid pathways. Enkephalins are natural ligands of opioid receptors, with strong affinity for δ-opioid receptors. Expression of functional δ-opioid receptors increases in sensory neurons after peripheral nerve injury in neuropathic pain models...

When a wetting liquid is displaced by air in a capillary tube, a wetting film develops between the tube wall and the air that is responsible for the snap-off mechanism of the gas phase. By dissolving a dye in the wetting phase it is possible to relate a measure of the absorbance in the capillary to the thickness of liquid films. These data could be used to compare with cutting edge numerical simulations of the dynamics of snap-off for which experimental and numerical data are lacking. Drainage experiments in constricted capillary tubes were performed where a dyed wetting liquid is displaced by air for varying flow rates...

OBJECTIVES: To assess how much Holmium laser enucleation of the prostate (HoLEP) is detrimental on men sexuality. METHODS: Between January and December 2013, all patients presented for BPH surgery were assessed using IIEF-15 (international index of erectile function-15) and Ej-MSHQ (ejaculatory domain-male sexual health questionnaire). Changes in men's sexuality following HoLEP in relation to control procedure were prospectively assessed. Intervention group included legible consecutive patients treated by HoLEP...

Viral hepatitis is a serious problem worldwide that was under-recognized till recently. The prevalence of chronic hepatitis C virus (HCV) is estimated to be 180 million people worldwide. Treatment of chronic HCV using combined pegylated interferon and ribavirin (PEG/RIBA) has long been the standard of care with modest response. In our study, we will report the real-life experience of serious adverse events (SAEs) that were reported by the National Committee for Control of Viral Hepatitis (NCCVH, Cairo, Egypt) program while treating chronic HCV using the triple therapy, sofosbuvir combined with pegylated interferon and ribavirin (PEG/RIBA/SOF), which led to premature discontinuation of treatment...

BACKGROUND: Lemon (Citrus limon) is a flowing plant belonging to the Rutaceae family. Citrus plants constitute one of the main valuable sources of essential oil used in foods and medicinal purposes. METHODS: In this study, we assessed chemical composition, antioxidant and antimicrobial activities of C. limon essential oil (ClEO) with its preservative effect against Listeria monocytogenes inoculated in minced beef meat. Gas chromatography/mass spectrometry (GC-MS) was used to identify the major components of the obtained ClEO...

In this study, solid dispersions of prednisolone (PRD) and bovine serum albumin (BSA) were prepared by spray drying and freeze drying methods using a PRD:BSA solution (20:1 Molar Ratio (MR)). PRD-BSA dispersed mixtures were characterised by scanning electron microscopy (SEM), and powder X-ray diffraction (XRD), and differential scanning calorimetry (DSC). PRD-BSA physical and dispersed mixtures showed significantly higher solubility in water than that of unprocessed drug. Enhancement factor of six was obtained in both physical mixture and solid dispersion solubility studies...

Post-stroke dysphagia is common, associated with poor outcome and often requires non-oral feeding/fluids. The relationship between route of feeding and outcome, as well as treatment with glyceryl trinitrate (GTN), was studied prospectively. The Efficacy of Nitric Oxide in Stroke (ENOS) trial assessed transdermal GTN (5 mg versus none for 7 days) in 4011 patients with acute stroke and high blood pressure. Feeding route (oral = normal or soft diet; non-oral = nasogastric tube, percutaneous endoscopic gastrostomy tube, parenteral fluids, no fluids) was assessed at baseline and day 7...

BACKGROUND: Evidence on height and prostate cancer risk is mixed, however, recent studies with large data sets support a possible role for its association with the risk of aggressive prostate cancer. METHODS: We analysed data from the PRACTICAL consortium consisting of 6207 prostate cancer cases and 6016 controls and a subset of high grade cases (2480 cases). We explored height, polymorphisms in genes related to growth processes as main effects and their possible interactions...

In this paper we explore the role of suppressor of cytokine signaling 1 (SOCS1) (rs243327), the regulator of toll-like receptor-9 (TLR9) (rs352140), retinoic acid inducible gene-I (RIG-I) (rs669260), and cluster of differentiation 152 (CD152) (rs231776) in fibrotic/cirrhotic patients. Single nucleotide polymorphisms (SNPs) within these genes as well as haplotype analyses were performed on a cohort of 120 Egyptian fibrotic patients. Fibrosis had progressed from HCV genotype 4 infections. Using RT-PCR, SNPs were evaluated in the DNA collected from each patient using TaqMan(®) genotyping assays...

The aim of this study was to test the hypothesis that pomegranate juice supplementation would blunt acute and delayed oxidative stress responses after a weightlifting training session. Nine elite weightlifters (21.0 ± 1 years) performed two Olympic-Weightlifting sessions after ingesting either the placebo or pomegranate juice supplements. Venous blood samples were collected at rest and 3 min and 48 h after each session. Compared to the placebo condition, pomegranate juice supplementation attenuated the increase in malondialdehyde (-12...

Troponin is a specific cardiac infarction isoform (TnIc, TnTc) and its determination is used for the diagnosis of myocardial infarction even with normal Electrocardiography. The increase of cardiac troponins occurs in a variety of clinical situations without an acute coronary syndrome (ACS), cardiologists and emergency physicians are often confronted with positive troponins that are difficult to interpret. Few data exist about the occurrence, the clinical characteristics and the predictive value in case of absence of ACS...
