Objective： Analysis of abstinence rates of smokers per gender at 3, 6, 9 and 12 months in a Smoking Cessation Unit from January 2008 to December 2009. Methods： Descriptive retrospective study. Analysis of socio-demographic variables, smoking patterns, associated comorbidities, continuous abstinence rates, success, relapses, failure and dropping out. Results： 278 smokers started treatment （33%）; 55.4% males and 44.6% females （mean age of 48.3 and 44.06 years, respectively）. The main associated comorbidities were： psychiatric （38.7%）, cardiovascular （dyslipemia 25%） and respiratory （COPD （chronic obstructive pulmonary disease） 9.7%） in females; cardiovascular （dyslipemia 34.4%）, psychiatric （34.4%） and respiratory （COPD 19.5%） in males. VRN （Varenicline） was prescribed in 40.2% males and 32.2% females; NRT （nicotine replacement therapy） was used in 46.6% and 38.7%, respectively; bupropion was employed in 6.5% and 21.8%, respectively. Psychological counseling was offered only to 7.8% males and 8.1% females. The continuous abstinence rates in males at 3, 6, 9 and 12 months were 51.3%, 37.7%, 32.5% and 30.5%, respectively, and were 45.2%, 29.8%, 25.0% and 24.2% for females. Failure was 9.7% for females and 18.8% for males. Success was more frequent for those on VRN （n = 41 males; n = 12 females）. No relapses were indicated for 42 females and 71 males. The percentage of relapses was higher at 3 months （29.0% females, 19.5% males）. Conclusions： The study observed differences in treating abstinence between genders （in the abstinence rates and failure index）. This implies having to consider incorporating the gender variable into the diagnosis, treatment and prevention of smoking.

中国新生代黄土序列具有沉积速率高、连续性好等特点,记录了东亚地区持续的古气候动力学演化和重大地质事件信息。受区域构造-地貌和大气环流格局影响,中生代晚期华南发育了众多盆山型古沙漠系统且出露了巨厚的风成砂,但几乎未有学者提及黄土/黄土类似物的存在。本文通过粒度端元解析、野外露头的构型分析等手段,对衡阳盆地上白垩统红花套组进行了初步研究,识别出风成砂丘、砂席和泥滩等环境类型;并在泥滩环境中提取到黄土类似物的粒度组分信号,同时提出了黄土类似物的风成成因,总结了其形成-堆积过程。这项工作旨在探索白垩纪黄土类似物存在的可能性,为未来开展华南陆块中生代风尘记录研究提供契机。

Deposition of the H2A.Z histone variant by the SWR1 complex （SWRI-C） in regulatory regions of specific loci modulates transcription. Characterization of mutations in Arabidopsis thaliana homologs of yeast SWRI-C has revealed a role for H2A.Z exchange in a variety of developmental processes. Nevertheless, the exact composition of plant SWRI-C and how it is recruited to target genes remains to be established. Here we show that SWC4, the Arabidopsis homolog of yeast SANT domain protein Swc4/Eaf2, is a DNA-binding protein that interacts with SWR1-C subunits. We demonstrate that the swc4-1 knockout mutant is embryo- lethal, while SWC4 RNAi knockdown lines display pleiotropic phenotypic alterations in vegetative and repro- ductive traits, including acceleration of flowering time, indicating that SWC4 controls post-embryonic processes. Transcriptomic analyses and genome-wide profiling of H2A.Z indicate that SWC4 represses tran- scription of a number of genes, including the floral integrator FT and key transcription factors, mainly by modulating H2A.Z deposition. Interestingly, SWC4 silencing does not affect H2A.Z deposition at the FLC locus nor expression of this gene, a master regulator of flowering previously shown to be controlled by SWR1-C. Importantly, we find that SWC4 recognizes specific AT-rich DNA elements in the chromatin regions of target genes and that SWC4 silencing impairs SWRI-C binding at FT. Collectively, our data suggest that SWC4 regulates plant growth and development by aiding SWR1-C recruitment and modulating H2A.Z deposition.

AIM: To investigate the prevalence and penetrance of hMSH6 mutations in Spanish HNPCC families that was negative for mutation in hMLH1 or ***: We used PCR-based DGGE assay and direct Sequencing to screen for hMSH6 gene in 91 HNPCC ***: we have identified 10 families with germ-line mutations in the DNA sequence. These mutations included two intronic variation, three missense mutation, one nonsense mutation, and four silent mutations. Among the 10 germ-line mutations identified in the Spanish cohort,8 were novel, perhaps, suggesting different mutational spectra in the Spanish population. Detailed pedigrees were constructed for the three families with a possible pathogenic hMSH6 mutation. The two silent mutations H388H and L758L, detected in a person affected of colorectal cancer at age 29, produce loss of the wild-type allele in the tumor sample. Immunohistochemical analysis showed that expression of MSH6 protein was lost only in the tumors from the carriers of V878A and Q263X ***: Altogether, our results indicate that disease-causing germ-line mutations of hMSH6 are very less frequent in Spanish HNPCC families.

OBJECTIVE: To summarize the literature about the effectiveness of dry needling(DN) on relieving pain and increasing range of motion(ROM) in individuals with myofascial pain syndrome(MPS).METHODS: Papers published from January 2000 to January 2013 were identified through an electronic search in the databases MEDLINE, Dialnet, Cochrane Library Plus, Physiotherapy Evidence Database(pedro) and Spanish Superior Council of Scientific Research(CSIC). The studies included were randomized controlled trials written in English and/or Spanish about the effectiveness of DN on pain and ROM in individuals with ***: Out of 19 clinical trials that were potentially relevant, a total of 10 were included in the Meta-analysis. Regarding pain intensity reduction when measured before and immediately after the intervention, DN achieved improvement compared with the placebo treatment [d =-0.49; 95% CI(-3.21, 0.42)] and with the control group [d =-9.13;95% CI(- 14.70,- 3.56)]. However, other treatments achieved better results on the same variable compared with DN, considering the measurements for pre-treatment and immediately after [d = 2.54;95% CI(-0.40, 5.48)], as well as the pre-treatment and after 3-4 weeks [d = 4.23; 95% CI(0.78, 7.68)].DN showed a significantly increased ROM when measured before the intervention and immediately after, in comparison with the placebo [d = 2.00;95% CI(1.60, 2.41)]. However, other treatments achieved a significant better result regarding ROM when it was measured before the intervention and immediately after, as compared with DN [d =-1.42;95% CI(-1.84,-0.99)].CONCLUSION: DN was less effective on decreasing pain comparing to the placebo group. Other treatments were more effective than DN on reducing pain after 3-4 weeks. However, on increasing ROM,DN was more effective comparing to that of placebo group, but less than other treatments.

We expose a case of a woman with hypertension and hypokalemia. The differential diagnosis should include primary hyperaldosteronism, diuretics or lazantes intake, secondary hyperaldosteronism. In this patient, additional tests performed show no cause of hormonal disruption and the whole picture is due to a high intake of licorice. Glycyrrhetinic acid, the active component of licorice, inhibits renal IIbeta-hydroxisteroid dehydrogenase. This allows cortisol to stimulate mineralocorticoid receptors. Licorice ingestion should be considered in the differential diagnosis of hypertension with hypokalemia.

In this paper the Delaware Method published in 1963 is analyzed and upgraded with using correction factors which take into account the undesirable currents of the mean flow. However, this method presents graphically these correction factors which imply an impediment to fulfill the software calculations. Thus, the equations corresponding to the correction factor equations and a Fortran 77 numerical program were established. This system is given to explore different design alternatives in order to find the optimal solution to each proposed problem. The results of this work was a simple software that can perform calculations with the introduction of parameters depending only on the geometry of the heat exchanger, i.e., geometry, temperature and fluid characteristics eliminating the human errors and increasing the calculations speed and accuracy.
