Building bridges to chemistry through biological contents

Mareike Janssen & Martin Gröger
Abstract: In contrast to biological contents, chemical contents are still underrepresented in primary schools, although they are implemented in the curricula. This problem is largely due to an inadequate education of primary school teachers and a resulting lack of positive attitudes towards chemical contents and of interest in them. Closely related is a widespread negative self-concept for chemical topics and a low self-efficacy to teach them. In order to address this problem, a university seminar...

Nosocomial infections and antibiotic resistance pattern in open-heart surgery patients at Imam Ali Hospital in Kermanshah, Iran

Fatemeh Heydarpour, Youssef Rahmani, Behzad Heydarpour & Atefeh Asadmobini
Background: Patients undergoing open heart surgery have a relatively high risk of acquiring nosocomial infections. The development of antibiotic-resistant infections is associated with prolonged hospital stays and mortalities. Objectives: The present study was conducted to investigate nosocomial infections and the antibiotic resistance pattern in bacteria causing these infections in open heart surgery patients at Imam Ali Hospital in Kermanshah in the west of Iran over a 4-year period from March 2011 to March 2014.

Bioactive potential of apigenin derivative apigenin-7-O-glucoside related to its antifungal activity on Candida spp. and cytotoxic effect on colon cancer cells was studied and compared with bioactive potential of apigenin. Antifungal activity was tested on 14 different isolates of Candida spp. using membrane permeability assay, measuring inhibition of reactive oxidative species and inhibition of CYP51 C. albicans enzyme. Cytotoxic potential of apigenin-7-O-glucoside was tested on colon cancer HCT116 cells by measuring cell viability, apoptosis rate...

Osteogenic differentiation of mesenchymal stem cells cultured on PLLA scaffold coated with Wharton’s jelly

Marziehsadat Ahmadi, Ehsan Seyedjafari, Seyed Jalal Zargar, Gebremariam Birhanu, Ali Zandi-Karimi, Bahareh Beiki & Kadriye Tuzlakoglu
Poly-L-lactic acid (PLLA) electrospun nanofiber scaffold is one of the most commonly used synthetic polymer scaffolds for bone tissue engineering application. However, PLLA is hydrophobic in nature, hence does not maintain proper cell adhesion and tissue formation, moreover, it cannot provide the osteo-inductive environment due to inappropriate surface characteristic and the lack of surface motives participating in the first cellular events. To modify these shortcomings different approaches have been used, among those the most commonly...

Fracture heuristics: surgical decision for approaches to distal radius fractures. A surgeon’s perspective

Florian Wichlas, Serafim Tsitsilonis, Sebastian Kopf, Björn Dirk Krapohl & Sebastian Manegold
Introduction: The aim of the present study is to develop a heuristic that could replace the surgeon’s analysis for the decision on the operative approach of distal radius fractures based on simple fracture characteristics. Patients and methods: Five hundred distal radius fractures operated between 2011 and 2014 were analyzed for the surgeon’s decision on the approach used. The 500 distal radius fractures were treated with open reduction and internal fixation through palmar, dorsal, and dorsopalmar...

Comparative experimental study on two designed intravenous anaesthetic combinations in dogs

Abdelnaser A.A. Abdel-Hady, Khaled M. Abdelbasset & Ahmed S. Soliman
The goal of the present study is to design a good anaesthetic program for dogs which can lead to optimal anaesthesia with no or minimal post-operative adverse effects. For this purpose, we designed two anaesthetic combinations and compared their effects in Mongrel dogs: combination ‘A’ consisting of atropine, xylazine, ketamine plus propofol, and combination ‘B’ consisting of atropine, diazepam, ketamine plus propofol. The onset and duration of anaesthesia induction, the duration of maintenance as well...

Anti-aging activities of extracts from Tunisian medicinal halophytes and their aromatic constituents

A. Jdey, H. Falleh, S. Ben Jannet, K. Mkadmini Hammi, X. Dauvergne, C. Magné & R. Ksouri
Six medicinal halophytes widely represented in North Africa and commonly used in traditional medicine were screened for pharmacological properties to set out new promising sources of natural ingredients for cosmetic or nutraceutical applications. Thus, Citrullus colocynthis, Cleome arabica, Daemia cordata, Haloxylon articulatum, Pituranthos scoparius and Scorzonera undulata were examined for their in vitro antioxidant (DPPH scavenging and superoxide anion-scavenging, β-carotene bleaching inhibition and iron-reducing tests), antibacterial (microdilution method, against four human pathogenic bacteria) and anti-tyrosinase...

JANUS database

Paul Schofield
JANUS is a collection of data and tissue samples from materials made at different US National Laboratories during animal studies done between 1950�s and 1990�s. The Janus experiments, carried out at Argonne National Laboratory from 1972 to 1989 and supported by grants from the US Department of Energy, investigated the effects of neutron and gamma radiation on mouse tissues primarily from B6CF1 mice. Data and paraffin embedded tissues from thousands of mice and dogs exposed...

EPI-CT scan cohort

Paul Schofield
EPI-CT is a multinational cohort study of children and young adults who have undergone at least one computed tomography (CT) scan before the age of 22 years. It comprises three main parts: 1) an epidemiological cohort study assessing cancer effects of radiation exposure from CT; 2) a dosimetry system to evaluate individual doses and related uncertainty, and supporting dose reduction and optimisa on strategies; 3) a pilot study to evaluate the feasibility of applying diferent...

Upper eyelid angiolipoma associated friction in the glide zone

Selman Karaci, Ayten Livaoğlu, Rüştü Köse & Barış Kömür
A 74-year-old man was examined for a mass in the left upper eyelid. It was inconspicuous in inspection. There was no visual restriction, however a feeling of friction on the superior orbit during lid movement. Through eyelid crease lid incision, a solitary lesion appeared in the preaponeurotic space that orginated from the upper tarsal plate. Excisional biopsy revealed adipose proliferation with patch form vessels. This case represents the second reported angiolipoma of the eyelid in...

3-generation Exposure Study

Paul Schofield
The Semipalatinsk nuclear test site (STS) is located approximately 150 km west of the city of Semipalatinsk (now called Semey), and was a major site for nuclear weapons testing by the former Soviet Union. It was here that the Soviet Union conducted their first nuclear test on 29 August 1949. Later, 465 nuclear explosions were carried out between 1949 and 1989, including 118 atmospheric events (88 air events and 30 surface events) from 1949-1962. The...
