Tropical woody species occurring in limestone outcrops are frequently exposed to particulate material from cement factories. The effects of 60-day cement dust exposure on physiological traits and enzymatic antioxidant system of young plant leaves of Guazuma ulmifolia Lam., Myracrodruon urundeuva Allemão and Trichilia hirta L. were investigated. Cement dust (2.5 or 5mgcm(-2)) was applied to the leaf surface or soil or both (leaf plus soil) and plants were maintained at greenhouse. Cement dust barely affected the mineral nutrient levels, except for iron whose content was decreased in leaves/leaflets of all species studied...

Purpose: Although lexical information influences phoneme perception, the extent to which reliance on lexical information enhances speech processing in challenging listening environments is unclear. We examined the extent to which individual differences in lexical influences on phonemic processing impact speech processing in maskers containing varying degrees of linguistic information (2-talker babble or pink noise). Method: Twenty-nine monolingual English speakers were instructed to ignore the lexical status of spoken syllables (e...

OBJECTIVES: After total hip arthroplasty (THA), restoration of hip center of rotation (COR) is essential to ensure stability of the prosthetic hip and longevity of the prosthesis. Our aim was to determine whether, and how, the COR changed postoperatively compared to the native COR following implantation of a cementless acetabular component in anatomical position and to compare the accuracy of cup placement between two surgeons with different levels of surgical experience. MATERIALS AND METHODS: We evaluated 145 patients (145 hips) who underwent unilateral primary THA, who had no distorted acetabulum on the affected hip and a normal contralateral hip...

INTRODUCTION: Despite sharing common psychosocial and developmental experiences, adolescents living with perinatally and behaviourally acquired HIV-1 infection are different in terms of timing of HIV infection and developmental stage at infection. Therefore, it is of interest to identify similarities and differences between these two groups of adolescents living with HIV in their experiences, facilitators and barriers during the transition process. METHODS: A detailed literature search of peer-reviewed published papers was conducted on PubMed to identify relevant original research or viewpoints published up to September 2016...

We investigate the sensitivity of the relict, endemic Cretan tree species Zelkova abelicea (Lam.) Boiss. (Ulmaceae) to several climate variables (temperature, precipitation and drought). For this purpose, we establish the first centennial tree-ring chronology for the species, and the first ever tree-ring chronology for a broadleaved species on Crete. We demonstrate the strong sensitivity of Z. abelicea towards precipitation and drought in late spring to early summer and the absence of a significant response to abundant precipitation occurring during winter or early spring...

REVIEW
Shachar Moshe Aharony, Ornella Lam, Jacques Corcos
Multiple sclerosis (MS) is a unique neurological disease with a broad spectrum of clinical presentations that are time- and disease course-related. MS plaque location (intracranial and/or spinal) is a key feature in the pathophysiology of disease-related lower urinary tract symptoms (LUTS). The prevalence of these symptoms in MS patients is very high, with nearly 90% of them experiencing some degree of voiding dysfunction and/or incontinence. LUTS rarely present as primary MS manifestations and usually appear 6-8 years after the initial diagnosis...

Background and aims Endoscopic retrograde cholangiopancreatography (ERCP) in patients who have undergone Roux-en-Y gastric bypass (RYGB) is technically challenging. We describe our multicenter experience using lumen-apposing metal stents (LAMSs) to create an endoscopic ultrasound-guided transgastric fistula (EUS-TG) to facilitate peroral ERCP in these patients. Patients and methods Thirteen patients with RYGB who underwent EUS-TG at three tertiary centers were included. EUS was used to guide puncture of the excluded stomach from the gastric pouch or jejunum; a LAMS was placed across the transgastric fistula...

BACKGROUND: Critically ill pediatric patients are considered at high risk for medication errors. Although much research focuses on the actual errors, equally important are medication errors that, although intercepted, carried the potential for an adverse drug event. The aim of this study was to determine the occurrence of prescribing errors and potential adverse drug events (pADEs) in a local pediatric intensive and critical care unit (PICU) in Hong Kong. Our secondary objective was to determine the type of error, nature of medication involved and the time of error occurrence...

PURPOSE: Preoperative antibiosis contributes up to one third of total antibiotic use in major hospitals. Choice of antibiotic is not uniformly standardized, and polypharmacy regimens may be used without knowing the effect on rates of surgical site infection, nonsurgical infections, or antibiotic resistance. Careful examination of trends in surgical prophylaxis is warranted. In this study, we aimed to examine our institution's experience with vagus nerve stimulator (VNS) implantation, focusing on association between perioperative antibiotic practices and postoperative infectious outcomes...

BACKGROUND: Optimal management of locally recurrent prostate cancer after definitive radiation therapy is still challenging. With the development of highly accurate radiotherapy devices, prostate salvage re-irradiation might generate lower toxicity rates than classical salvage therapies. We retrospectively evaluated the toxicity and the feasibility of a prostate re-irradiation after definitive radiation therapy failure. Two modalities were investigated: high-dose-rate brachytherapy (HDRB) on whole prostate gland and focal stereotactic radiotherapy (SBRT) using CyberKnife® linac...
