AbstractBackgroundRecent attempts in the USA and Europe to ban the circumcision of male children have been unsuccessful. Of current concern is a report by the Tasmanian Law Reform Institute (TLRI) recommending that non-therapeutic circumcision be prohibited, with parents and doctors risking criminal sanctions except where the parents have strong religious and ethnic ties to circumcision. The acceptance of this recommendation would create a precedent for legislation elsewhere in the world, thereby posing a threat to pediatric practice, parental responsibilities and freedoms, and public health.DiscussionThe TLRI report ignores the scientific consensus within medical literature about circumcision. It contains legal and ethical arguments that are seriously flawed. Dispassionate ethical arguments and the United Nations Convention on the Rights of the Child are consistent with parents being permitted to authorize circumcision for their male child. Uncritical acceptance of the TLRI report’s recommendations would strengthen and legitimize efforts to ban childhood male circumcision not just in Australia, but in other countries as well. The medical profession should be concerned about any attempt to criminalize a well-accepted and evidence-based medical procedure. The recommendations are illogical, pose potential dangers and seem unworkable in practice. There is no explanation of how the State could impose criminal charges against doctors and parents, nor of how such a punitive apparatus could be structured, nor how strength of ethnic or religious ties could be determined. The proposal could easily be used inappropriately, and discriminates against parents not tied to the religions specified. With time, religious exemptions could subsequently be overturned. The law, governments and the medical profession should reject the TLRI recommendations, especially since the recent affirmative infant male circumcision policy statement by the American Academy of Pediatrics attests to the significant individual and public health benefits and low risk of infant male circumcision.SummaryDoctors should be allowed to perform medical procedures based on sound evidence of effectiveness and safety with guaranteed protection. Parents should be free to act in the best interests of the health of their infant son by having him circumcised should they choose.

Abstract

Background
Iraqi Kurdistan region is one of the areas where female genital mutilation is reportedly widely practiced but inadequately studied. The aim of this study was to determine (i) the prevalence of female genital mutilation among Muslim Kurdish women in Erbil city, (ii) the patterns and types of female genital mutilation, (iii) the factors associated with this practice and (iv) women’s knowledge and attitudes towards this practice.

Methods
A cross-sectional study was conducted in the primary health care centers and the Maternity Teaching Hospital in Erbil city, involving 1987 women aged 15–49 years. Data were obtained about female genital mutilation status and knowledge and perception towards this practice. The participants were clinically examined to verify the self-reported female genital mutilation status.

Results
The self-reported prevalence of female genital mutilation was 70.3%, while it was 58.6% according to clinical examination of the women’s genitalia. The most common type of female genital mutilation was type I (99.6%) and the most common age at which mutilation was performed was 4–7 years (60.2%). This practice was mostly performed by traditional birth attendants (72.5%). Only 6.4% of mutilated women reported having complications after mutilation, most commonly bleeding (3.6%). The practice was more reported among housewives (OR = 3.3), those women whose mothers were mutilated (OR = 15.1) or with unknown mutilation status (OR = 7.3) and those women whose fathers were illiterate (OR = 1.4) or could only read and write (OR = 1.6). The common reasons for practicing female genital mutilation were cultural tradition (46.7%) and dictate of religion (38.9%). Only 30% of the participants were aware about the health consequences of female genital mutilation. More than one third (36.6%) of the women support the practice and 34.5% have intention to mutilate their daughters.

Conclusions
Prevalence of female genital mutilation among Muslim Kurdish women in Erbil city is very high; although, most cases are of type I. There is clear lack of knowledge about the health consequences of female genital mutilation and a relatively important segment of women support this practice. Custom or tradition and dictate of religion are the main reasons for this practice that need further in-depth exploration.
The possible impact of an alcohol welfare surcharge on consumption of alcoholic beverages in Taiwan
Authors: Yeh Chun-Yuan , Ho Li-Ming , Lee Jie-Min , Hwang Jhe-Yo 
Published: September 2013

Abstract

Background
The abuse of alcoholic beverages leads to numerous negative consequences in Taiwan, as around the world. Alcohol abuse not only contributes to cardiovascular disease, hypertension, diabetes and cancer, but it is also an underlying cause of many other serious problems, such as traffic accidents, lost productivity, and domestic violence. International leaders in health policy are increasingly using taxation as an effective tool with which to lower alcohol consumption. In this study, we assessed how consumption patterns in Taiwan would be affected by levying a welfare surcharge on alcoholic beverages of 20%, 40% or 60% in accordance with the current excise tax. We also assessed the medical savings Taiwan would experience if consumption of alcoholic beverages were to decrease and how much additional revenue a welfare surcharge would generate.

Methods
We estimated the elasticity of four types of alcoholic beverages (beer, wine, whisky and brandy) using the Central Bureau of Statistics (CBS) Demand Model. Specifically, we estimated alcohol’s price elasticity by analyzing the sales prices and time statistics of these products from 1974 to 2009.

Results
Alcoholic beverages in Taiwan have the following price elasticities: beer (−0.820), wine (−0.955), whisky (−0.587), brandy (−0.958). A welfare surcharge tax of 40% in accordance with the excise tax would decrease overall consumption of beer, wine, whisky and brandy between 16.24% and 16.42%. It would also generate New Taiwan Dollar (NT$) revenues of 5.782 billion to 5.993 billion. Savings in medical costs would range from NT$871.07 million to NT$897.46 million annually.

Conclusions
A social and welfare surcharge of 40% on alcoholic beverages in Taiwan would successfully lower consumption rates, decrease medical costs, and generate revenue that could be used to educate consumers and further decrease consumption rates. Consequently, we strongly recommend that such a tax be imposed in Taiwan.
Surface-associated MUC5B mucins promote protease activity in Lactobacillus fermentum biofilms
Authors: Wickström Claes , Chávez de Paz Luis , Davies Julia R , Svensäter Gunnel 
Published: September 2013

AbstractBackgroundMucosal surfaces are coated with layers of mucus gel that protect the underlying tissues and promote colonization by members of the commensal microflora.Lactobacillus fermentumis a common inhabitant of the oral cavity, gastrointestinal and reproductive tracts and is one of the most important lactic acid bacteria contributing to the formation of a healthy intestinal microflora. We have investigated the proteolytic activity inL. fermentumin response to interactions with the MUC5B mucin, which is a major component of mucus gels at sites colonized by this micro-organism.MethodsBiofilms ofLactobacillus fermentumwere established in mini-flow cells in the presence or absence of human salivary MUC5B. The proteolytic activity of biofilm cells was examined in a confocal scanning laser microscope with a fluorescent protease substrate. Degradation of MUC5B byL. fermentumwas analysed using SDS-PAGE followed by Western blotting with antisera raised against the MUC5B peptide. Cell surface proteins differentialy expressed in a MUC5B-rich environment were identified with the aid of comparative two-dimensional electrophoresis followed by LC-MS/MS.ResultsLactobacillus fermentumadhered well to surfaces coated with MUC5B mucin and in biofilms ofL. fermentumformed in a MUC5B environment, the proportion of proteolytically-active cells (47±0.6% of the population), as shown by cleavage of a fluorescent casein substrate, was significantly greater (p<0.01) than that in biofilms formed in nutrient broth (0.4±0.04% of the population). Thus, the presence of MUC5B mucins enhanced bacterial protease activity. This effect was mainly attributable to contact with surface-associated mucins rather than those present in the fluid phase. Biofilms ofL. fermentumwere capable of degrading MUC5B mucins suggesting that this complex glycoprotein can be exploited as a nutrient source by the bacteria.Comparison of the surface proteomes of biofilm cells ofL. fermentumin a MUC5B environment with those in nutrient broth using two-dimensional electrophoresis and mass spectroscopy, showed that the enhanced proteolytic activity was associated with increased expression of a glycoprotease;O-sialoglycoprotein endopeptidase, as well as chaperone proteins such as DnaK and trigger factor.ConclusionsAdhesion to mucin-coated surfaces leads to a shift towards a more protease-active phenotype withinL. fermentumbiofilms and proteases produced within the biofilms can degrade MUC5B mucins. The enhanced proteolytic activity was associated with an increase inO-sialoglycoprotein endopeptidase on the cell surface. We propose that the upregulation of chaperone proteins in the mucin environment may contribute to the protease-active phenotype through activation of the glycopeptidase. This would represent one way for commensal lactobacillie.g. L. fermentumto exploit complex substrates in their local environment in order to survive on mucosal surfaces.

Abstract

Background
Over-proliferation of airway smooth muscle cell (ASMC) is one of the important contributors to airway remodeling in asthma. The aim of this study was to investigate the effect of Shenmai injection (SMI) on the proliferation of the rat ASMC in asthma.

Methods
Rats were randomly divided into three groups: the control group, the asthma group, and the SMI treatment group. Reverse transcription-polymerase chain reaction (RT-PCR) and immunocytochemistry staining were used to detect the mRNA and protein expression of transient receptor potential vanilloid 1 (TRPV1) and proliferating cell nuclear antigen (PCNA) in rat ASMC respectively. Intracellular Ca2+ concentration ( [Ca2+]i ) in rat ASMC were measured with Fluo-3/AM by confocal microscopy. The proliferation was detected by MTT assay.

Results
Compared with the control group, the asthma group showed an increased expression of TRPV1 and [Ca2+]i in rat ASMC. The expression of PCNA and absorbance of MTT assay in asthma rat ASMC was also significantly increased. SMI could significantly decrease the expression of TRPV1 channel and [Ca2+]i in the asthmatic rat ASMC. Furthermore, the expression of PCNA and absorbance of MTT assay in asthmatic rat ASMC was significantly reduced after SMI treatment.

Conclusions
SMI may prevent asthma-induced ASMC over-proliferation probably by inhibiting the expression of TRPV1 channel, which regulates the intracellular calcium concentration.
The use of microblog-based case studies in a pharmacotherapy introduction class in China
Authors: Wang Tiansheng , Wang Fei , Shi Luwen 
Published: September 2013

Abstract

Background
Microblog is a Web 2.0 technology that provides an online social networking platform for communicating and sharing information among web users. Pharmacy educators have previously used microblog to promote active engagement of students. However, there is very little research to demonstrate how to use microblogging effectively to enhance pedagogy in a blended or face-to-face classroom environment. We used the most popular microblog website in China to create a “space” within the classroom to evaluate an interactive microblogging forum for the integration of pharmacotherapy case studies. This study is aimed to determine students’ attitudes toward microblog-based case studies (MBC) in a pharmacotherapy class.

Methods
We created a group on Sina Weibo, the most popular microblog website in China, to explore the possibilities of using microblog-based case discussions in pharmacy education to promote and motivate student learning. The class teaching activities began in November 2011; individual group assignments to a single case study were administered to 21 groups with a total of 126 participating pharmacy students. Each group was required to share a discussion care plan on the microblogging platform. Individual students were expected to participate in an online discussion related to at least two other group cases by posting their comments on the microblog platform. All postings were tracked and analyzed, and then a post MBC survey was administered anonymously to determine students’ opinions towards MBC.

Results
A total of 126 students posted 592 messages and 112 students (89%) completed the survey. More than 80% of students agreed that MBC improved communication; nearly 70% agreed that MBC increased the amount of interaction, and over 50% found value in reading other students’ messages. However, 25% students believed the collaborative learning was not effective and 22% indicated the quality of interaction was low.

Conclusions
MBC appears to be well-accepted learning method to students in this study. Educators who wish to use MBC for pharmacy courses should balance the potential advantages, such as improving communication and the amount of interaction, with potential disadvantages, such as inefficient collaborative learning and the low quality of interaction.
Comparison of expression systems for the extracellular production of mannanase Man23 originated from Bacillus subtilis B23
Authors: Zhou Haiyan , Yang Yong , Nie Xu , Yang Wenjiao , Wu Yongyao 
Published: September 2013

Abstract

Background
Mannanase is an enzyme that can catalyze random hydrolysis of beta-1,4-mannosidic linkages in the main chain of mannans, glucomannans and galactomannans which are the key polymers in hemicellulose. It has been used in a number of different industrial applications including food, feed, pharmaceutical, pulp/paper industries, and second generation biofuel. To optimize the expression system of mannanase Man23 gene, two kinds of vectors and host bacteria were determined and compared.

Results
Recombinants pHY-p43-man23 and pBPS-man23 were constructed and transferred into Bacillus subtilis WB600 and Brevibacillus brevis respectively. For mannanase Man23 gene, recombinant pHY-p43-man23 expressed in Brevibacillus brevis had higher production and activity. Compared to the wild-type Bacillus subtilis B23, the production of recombinant pHY-p43-man23 in B. brevis increased by 10 times and activity increased by 21.3%. pHY-p43-man23 in B. brevis had activity at the range of 20 ~ 70°C but its optimum temperature was 50°C and had activity from pH 4 ~ 10 but its optimum pH was around 7. This demonstrated the recombinant had improved stability as well.

Conclusions
Mannanase is an important industrial enzyme and combination of vector pHY-p43 and host Brevibacillus brevis is a novel expression system for a mannanase decoding gene. This work aims at exploring a better expression system of mannanase Man23 decoding gene for industrial application.
Effect of DNA methylation inhibitor on RASSF1A genes expression in non-small cell lung cancer cell line A549 and A549DDP
Authors: Mengxi Duan , Qian Wang , Nan Wang , Xiaoguang Xiao , Shijun Li 
Published: September 2013

Abstract

Background
Ras association domain family 1A gene (RASSFlA) is a candidate suppressor gene, Lack of RASSF1A expression was found in lung cancer. High DNA methylation at the promoter region is the main reason for inactivating RASSF1A transcription.

Methods
In this study, we examined RASSF1A’s methylation status and its mRNA expression level between non-small cell lung cancer cell line A549 and anti-Cisplatin cell strain A549DDP, Furthermore, methylation of A549DDP was reversed by treatment of 5-Aza-2′ - deoxycytidine (5-Aza-cdR),a DNA methyltransferase inhibitor.

Results
We found that RASSF1A’s methylation status and its mRNA expression were obvious differences between A549 and A549DDP. 5-Aza-CdR treatment remarkablly reduced cell vability of A549DDP. Moreover, 5-Aza-CdR treatment induced A549DDP cell apoptosis in a dose dependent manner with declining cell percentage in S and G2/M stage, and increasing proportion in G0/G1 stage. Cell motility was blocked in G0/G1 stage. All of A549DDP cells showed unmethylated expression, its high methylation status was reversed in a dose-dependent manner within a certain range.

Conclusions
The abnormal gene methylation status of RASSF1A is a molecular biomarker in lung cancer diagnosis, treatment and prognosis.

Abstract

Background
Atherosclerosis is a chronic progressive inflammatory disease of blood vessels particularly the arteries. The development of atherosclerotic plaques or atherogenesis is a complex process that is influenced by cardiovascular risk factors such as vascular inflammation and dyslipidemia. This study demonstrates the ability of tumor necrosis factor-alpha (TNF-α) and low density lipoproteins (LDL) to induce atherosclerotic plaque in human saphenous vein (HSV) organ culture.

Methods
Normal HSV segments, from male patients who had coronary bypass graft, were cultured in DMEM containing 5% heat inactivated fetal bovine serum. TNF-α (5 ng/ml) was applied in combination with native LDL (nLDL) or oxidized LDL (oxLDL) at the dose of 50 μg/ml for 14 days. The phenotypic changes of the organ cultures characteristic of initial atherosclerotic plaques were evaluated. The effect of anti-atherogenic agent, 17-β estradiol (E2), was also determined.

Results
Histologic, histomorphometric, and immunohistochemical examinations revealed that HSV rings stimulated with TNF-α + nLDL or TNF-α + oxLDL can exhibit the essential morphological features of atherogenesis, including fibrous cap formation, cholesterol clefts, evident thickening of the intimal layer, increased proliferation of smooth muscle cells (SMC) and migration to the subendothelial layer, significant SMC foam cell formation, and increased expression of adhesion molecules in the vascular wall. Addition of E2 (50 nM) to the culture significantly modulated the critical changes. Consistently, mRNA profiling of the HSV model revealed that 50 of 84 genes of atherosclerosis were up-regulated.

Conclusions
Phenotypic changes characteristic of the initial development of atherosclerotic plaques can be induced in HSV organ culture.
Biological constraints limit the use of rapamycin-inducible FKBP12-Inp54p for depleting PIP2 in dorsal root ganglia neurons

Published: September 2013

Abstract

Background
Rapamycin-induced translocation systems can be used to manipulate biological processes with precise temporal control. These systems are based on rapamycin-induced dimerization of FK506 Binding Protein 12 (FKBP12) with the FKBP Rapamycin Binding (FRB) domain of mammalian target of rapamycin (mTOR). Here, we sought to adapt a rapamycin-inducible phosphatidylinositol 4,5-bisphosphate (PIP2)-specific phosphatase (Inp54p) system to deplete PIP2 in nociceptive dorsal root ganglia (DRG) neurons.

Results
We genetically targeted membrane-tethered CFP-FRBPLF (a destabilized FRB mutant) to the ubiquitously expressed Rosa26 locus, generating a Rosa26-FRBPLF knockin mouse. In a second knockin mouse line, we targeted Venus-FKBP12-Inp54p to the Calcitonin gene-related peptide-alpha (CGRPα) locus. We hypothesized that after intercrossing these mice, rapamycin treatment would induce translocation of Venus-FKBP12-Inp54p to the plasma membrane in CGRP+ DRG neurons. In control experiments with cell lines, rapamycin induced translocation of Venus-FKBP12-Inp54p to the plasma membrane, and subsequent depletion of PIP2, as measured with a PIP2 biosensor. However, rapamycin did not induce translocation of Venus-FKBP12-Inp54p to the plasma membrane in FRBPLF-expressing DRG neurons (in vitro or in vivo). Moreover, rapamycin treatment did not alter PIP2-dependent thermosensation in vivo. Instead, rapamycin treatment stabilized FRBPLF in cultured DRG neurons, suggesting that rapamycin promoted dimerization of FRBPLF with endogenous FKBP12.

Conclusions
Taken together, our data indicate that these knockin mice cannot be used to inducibly deplete PIP2 in DRG neurons. Moreover, our data suggest that high levels of endogenous FKBP12 could compete for binding to FRBPLF, hence limiting the use of rapamycin-inducible systems to cells with low levels of endogenous FKBP12.
Solitary intracranial osteoma with attachment to the falx: a case report
Authors: Chen Shu-Mei , Chuang Chi-Cheng , Toh Cheng-Hong , Jung Shih-Ming , Lui Tai-Ngar 
Published: September 2013

Abstract

Background
Intracranial osteomas are uncommon lesions that usually arise from the inner table of the cranium. There are few reports in the literature of intracranial osteomas with meninges attachment and without direct relation with the skull bone; these osteomas were mostly attached with dura. We report a rare osteoma with falx attachment.

Case
A 64-year-old woman presented with a 3-month history of intermittent tinnitus and dizziness. The scout film of petrous bone computed tomography scan revealed a high-density lesion in the frontal area. Magnetic resonance imaging showed a 2.5-cm mass attached to the surface of the falx in the right frontal parasagittal area. The patient underwent right frontal craniotomy, and a bony hard mass was found located in the right frontal parasagittal region extra-axially, with its medial surface attached to the falx. It could not be broken down by the cavitron ultrasonic surgical aspirator or even the cutting loop and was detached from the falx and removed in one piece. Histopathological examination showed a nodule with bony trabeculae and bone marrow tissue, compatible with osteoma. The postoperative course was uneventful, and the patient was discharged from the hospital with no neurological deficits one week after operation.

Conclusions
This is the first case report in the English literature of an intracranial osteoma arising from the falx. Because of their slow growth and their locations in silent brain areas, intracranial osteomas are usually diagnosed incidentally. Surgical resection is the primary treatment choice.
