medication review aims at optimizing the impact of medications while minimizing their related problems. Drug-related problems have never been properly addressed in Egyptian hospitals. The purpose of this paper is to record and compare the prevalence and types of medication related problems, the interventions provided by the clinical pharmacists and how physicians responded along with making recommendations for error prevention. This prospective study was conducted between June 2012 and December 2012, at an Egyptian general hospital. Five trained pharmacists recorded patient-specific medication related recommendations and completed quality-of-care interventions. The average number of audited doses was 81% of those prescribed. The most prevalent medication problem was prescribing errors followed by administration errors. A total of 20 patients experienced adverse drug events. The greatest error rates across the seven months were observed in the ICU and cardiology units. Numbers of interventions offered by the pharmacists ranged from 241, to 519 per month. Nurses accepted all the interventions introduced by the pharmacists aimed at reducing administration errors while physicians’ resistance rates had an average of 21%. This study showed a positive influence of the pharmacist-led medication review in reducing potential drug-related problems in an Egyptian secondary care where the hospital under study implemented new measures to minimize drug related problems according to the findings of the trained pharmacists.

OBJECTIVE To examine fatigue and quality of life (QOL) inbreast cancer patients undergoing chemotherapy or *** A self-report survey derived from the Chineseversion of Brief Fatigue Inventory, the Functional Assessmentof Chronic Illness Therapy for Breast Cancer, and the medicalOutcomes Study Social Support Survey. Descriptive statisticswas used to examine the intensity of fatigue and the prevalenceof severe fatigue. multivariate analysis of variance was used todetermine factors that affect the five domains of QOL among *** The majority of the participants (n = 261) perceiveda mild level of fatigue, but 35.6% of them suffered severe *** had a significantly negative association with all domainsof QOL except social/family wellbeing. The participants whowere receiving chemotherapy, undergoing curative treatment andhaving inadequate social support were more likely to have poorerQOL in all five domains (after adjustment for age).CONCLUSION Although the majority of the participantsexperienced a mild level of fatigue, there was a substantial groupof breast cancer patients who perceived their fatigue as severe. Thefindings of this study showed that fatigue had a detrimental effecton the various aspects of the participants' QOL. Demographic andclinical characteristics of breast cancer patients who were at riskof getting poorer QOL were identified. The results of the studydemonstrate that we should enhance healthcare professionals'awareness of the importance of symptom assessment, andprovide them with information for planning effective symptom-management strategies among this study population.

Host genetic factors may predict the outcome and treatment response in hepatitis C virus（HCV）*** of these factors is the single nucleotide polymorphisms of the interleukin 28B（IL28B）*** sought to evaluate the outcome of pegylated interferon and ribavirin therapy in association with IL-28B rs8099917 and rsl2980275 in patients infected with HCV genotype 4.A total of 180 patients with chronic hepatitis C were selected from Egyptians who have received combined therapy with pegylated interferon and ribavirin for 6 months and their response was evaluated after follow-up at 0,6,12,24 and 48 weeks from the beginning of the *** samples were collected from responders and *** DNA was extracted from whole blood and genotyping was carried out by polymerase chain reaction and restriction fragment length polymorphism（PCR-RFLP）.Our results showed that TT genotype of rs8099917 was associated with higher sustained viral response（SVR）rates and G allele represented a risk factor for failure of response（OR=3.7,CI=1.8：7.64）while rs12980275 was not significantly associated with SVR in genotype 4 Egyptian *** determination of 1L-28B SNPs may be useful in enhancing correct prediction of SVR achievement in treating this group of genotype 4 patients.

AIm： To cost-effectively express the 23-ku pE2, the most promising subunit vaccine encoded by the E2 fragment comprising of the 3＇-portion of hepatitis E virus （HEV） open reading frame 2 （ORF2） in plastids of tobacco （Nicotiana tabacum cv. SR1）, to investigate the transgene expression and pE2 accumulation in plastids, and to evaluate the antigenic effect of the plastid-derived pE2 in mice. mETHODS： Plastid-targeting vector pRB94-E2 containing the E2 fragment driven by rice psbA promoter was constructed. Upon delivery into tobacco plastids, this construct could initiate homologous recombination in psaB-trnfm and trnG-psbC fragments in plastid genome, and result in transgene inserted between the two fragments. The pRB94-E2 was delivered with a biolistic particle bombardment method, and the plastid-transformed plants were obtained following the regeneration of the bombarded leaf tissues on a spectinomycin-supplemented medium. Transplastomic status of the regenerated plants was confirmed by PCR and Southern blot analysis, transgene expression was investigated by Northern blot analysis, and accumulation of pE2 was measured by ELISA. Furthermore, protein extracts were used to immunize mice, and the presence of the pE2-reactive antibodies in serum samples of the immunized mice was studied by ELISA. RESULTS： Transplastomic lines confirmed by PCR and Southern blot analysis could actively transcribe the E2 mRNA. The pE2 polypeptide was accumulated to a level as high as 13.27 μg/g fresh leaves. The pE2 could stimulate the immunized mice to generate pE2-specific antibodies. CONCLUSION： HEV-E2 fragment can be inserted into the plastid genome and the recombinant pE2 antigen derived is antigenic in mice. Hence, plastids may be a novel source for cost-effective production of HEV vaccines.

The structural differences between m>E. colim> AmtB and the human RhCG as well as the Rh50 from m>Nitrosomonas europaeam> suggest different ammonia conduction mechanisms for the AmtB and the Rh proteins. This study investigates the mechanism differences by using molecular dynamics simulations on RhCG and Rh50NE structures. Unlike AmtB the Rh proteins lack the aromatic cage at the bottom of the periplasmic vestibule. This report establishes the periplasmic Glu residue as the NH+yle="margin-left:-10px;">4 binding site for Rh proteins, and the two Phe residues at the entrance of the pore as the NH3 binding site. The NH+yle="margin-left:-10px;">4 molecule pushed by another ammonium releases one of its protons on its way to the phenyl gate. This study also discovers that, unlike AmtB, the Rh protein pores allow water molecules, which eventually facilitates the NH3 conduction from periplasm to cytoplasm.
