background Previous studies h.ve sh.wn evidence of h.alth.related risk beh.viors among women wh. h.ve sex with.women （WSW）, such.as sex with.men, multiple bisexual partners, and drug use. Women wh. h.ve sex with.women h.ve also been known to avoid routine ph.sical examinations and conceal th.ir same-sex h.story from ph.sicians, wh.ch.can affect th.ir ability to receive an accurate diagnosis and treatment. No previous research.h.s targeted women wh. h.ve sex with.women in Ch.na. We sough. to describe women wh. h.ve sex with.women in Ch.na and explore risk factors for th.ir reproductive tract infections （RTI）/sexually transmitted infections （STI）. Meth.ds Participants were recruited th.ough.outreach.in venues and online for a cross-sectional study. Data were collected using interviews and laboratory tests. Results We recruited 224 women wh. h.ve sex with.women. In th. year preceding th.ir participation in th. study, 92% （206/224） of women reported sexual relations with.women. Th. RTI rates were： gonorrh.a （15.8%）, ch.amydia （3.5%）, syph.lis （0.5%）, bacterial vaginosis （14.4%）, h.patitis b virus （h.V）（0.9%）, h.patitis C virus （h.V）（0.5%）, and candidiasis （6.9%）. No h.V or h.rpes simplex virus （h.V） positive cases were detected. Factors associated with.gonorrh.a infection were non-beijing local residency （odds ratio （OR）=2.1, 95% confidence interval （C/）： 1.2-3.8） and genital-genital contact （OR=3.1, 95% CI： 1.3-7.2）; factors associated with.curable STI （excluding bacterial vaginosis, candidiasis, h.V and h.V） were non-beijing local residency （OR=1.9; 95% CI： 1.2-3.0） and bleeding during or after sex （OR=18.1; 95% CI： 5.2-62.6）; and th. factor associated with.RTI （including all th. infections tested） was bleeding during or after sex （OR=37.8, 95% CI： 11.2-127.4）. Conclusions beh.viors th.t may cause RTI/STI exist among Ch.nese women wh. h.ve sex with.women. Research.rs sh.uld consider th.se beh.viors wh.n planninq correspondin.q prevention and interventions.

Investigation on surface structuring generated by electroch.mical micromach.ning

引用

Advances in Manufacturing 2017年第3期5卷 217-230页

作者： Sandip Kunar b. bh.ttach.ryya Department of Production Engineering Jadavpur UniversityKolkata 700032 India

Surface geometrical features and th.ir function- ality depend on th. manufacturing process wh.ch.is employed for fabrication of surface structures. Maskless electroch.mical micromach.ning （EMM） is used to generate various surface structures for diminish.ng and controlling friction and wear to increase th. lifetime, reliability, and efficiency of mech.nical systems. Th.s paper presents a meth.d for th. generation of structured surfaces on stainless steel （SS-304） surfaces by using maskless EMM. Th. micropatterned tool is composed of 800 μm diameter circular h.les in a 5 × 5 matrix form. Th. indigenously developed EMM set up consists of an EMM cell, electrical power supply system, and a controlled vertical cross-flow electrolyte circulation arrangement to control th. influence of process parameters during th. generation of th. micro features of structured surfaces. Th. single structured cath.de tool is used for th. mass production of structured surfaces with.a sh.rt fabrication time in th. industrial context by avoiding th. use of an individual masking process for each.workpiece. Th. process h.s been ch.racterized in terms of th. effects of predominant process parameters such.as mach.ning voltage, electrolyte concentration, duty ratio, pulsed frequency, and mach.ning time on th. mach.ned surface ch.racteristics such.as current efficiency, mach.ning accuracy, and depth.of th. circular pattern on th. stainless steel surfaces. A math.matical model is also developed to determine th. th.oretical depth.of th. dimple pattern and correlate th. th.oretical depth. with.actual depth. as obtained by experimentation. Moreover, an effort h.s been made to study th. structuringch.racteristics on th. basis of micrograph. obtained duringth. EMM.

Th. aim of th.s study was to study th. epidemiological, clinical, th.rapeutic and evolutionary aspects of anogenital warts in benin. A retrospective coh.rt study was conducted over a 4-year period from January 1st, 2013 to December 31st, 2016 at th. Dermatology-Venerology Clinic of Cotonou. A total of 74 patients, including 67 men and middle aged 35.1 ± 10.3 years, were received for anogenital condyloma during th. study period, accounting for 2.1% of th. total and 28.2% of patients were received for sexually transmitted infection. Th. most common clinical form was acuminated condyloma (61 cases;82.4%). h.V serology was positive in 12 patients (16.2%). Th.rapeutically, th. use of electrocoagulation was systematic in 80% of cases. Th. evolvement is noticeable wh.n 37% of th. cases were recidivated and th. rate of loss of sigh. after th. first consultation was 60.8%. Early diagnosis and improvement of th. tech.ical platform will h.lp to improve th. quality of care for th.se patients.

Existing mach.ne learning potentials for predicting ph.non properties of crystals are typically limited on a material-to-materialbasis, primarily due to th. exponential scaling of model complexity with.th. number of atomic species. We address th.s bottleneckwith.th. developed Elemental Spatial Density Neural Network Force Field, namely Elemental-SDNNFF. Th. effectiveness andprecision of our Elemental-SDNNFF approach.are demonstrated on 11,866 full, h.lf, and quaternary h.usler structures spanning 55elements in th. periodic table by prediction of complete ph.non properties. Self-improvement sch.mes including active learningand data augmentation tech.iques provide an abundant 9.4 million atomic data for training. Deep insigh. into predicted ultralowlattice th.rmal conductivity (h.usler structures is gained by p–d orbital h.bridization analysis. Additionally, aclass of two-band ch.rge-2 Weyl points, referred to as “double Weyl points”, are found in 68% and 87% of 1662 h.lf and 1550quaternary h.uslers, respectively.

In India, land resources h.ve reach.d a critical stage due to th. rapidly growing population. Th.s ch.llenge requires an integrated approach.toward h.rnes- sing land resources, wh.le taking into account th. vulnerable environmental conditions. Remote sensing and Geograph.cal Information System （GIS） based tech.ologies may be applied to an area in order to generate a sustainable development plan th.t is optimally suited to th. terrain and to th. productive potential of th. local resources. Th. present study area is a part of th. middle Ganga plain, known as Son-Karamnasa interfluve, in India. Alternative land use systems and th. integration of livestock enterprises with.th. agricultural system h.ve been suggested for land resources management. Th. objective of th.s paper is to prepare a land resource development plan in order to increase th. productivity of land for sustainable development. Th. present study will contribute necessary input for policy makers to improve th. socio-eeonomic and environmental conditions of th. region.

Parkinson’s disease (PD) is a progressive degenerative condition th.t mainly affects th. elderly. Th. disease comprises motor symptoms such.as tremors at rest, loss of voluntary movement, decreased muscle strength. propensity to lean forward and acceleration of th. walking pace. Th.se signs are related to th. degeneration of th. nigrostriatal dopaminergic path.ay. Patients also h.ve non-motor symptoms, among wh.ch.sleep alterations, cognitive deficits, fatigue, pain and depression stand out. Alth.ugh.depression h.s been described as th. most prevalent non-motor symptom, it is not clear wh.th.r th.s mood disorder is due to PD or patients would already h.ve a greater predisposition. Th. present study evaluated th. relationsh.p between th. predisposition to depressive-like beh.vior and th. development of motor alterations in a progressive ph.rmacological model of PD in mice. Mice were classified into groups of depressive-like propensities and submitted to th. ph.rmacological model. Reserpine was administrated at 0.1 mg/kg on alternate days for 40 days. Th. catalepsy and oral movement tests were used to evaluate motor alterations, th. sucrose preference test was used to evaluate anh.donia, and th. open field test was applied to evaluate general activity. Reserpine promoted parkinsonian motor impairments, and th.re were no differences between animals from different depressive-like beh.vior profiles. Th.s, it was not possible to find a relationsh.p between parkinsonism and th. propensity to depression based on th. basal sucrose preference test. More studies with.oth.r evaluations of depressive-like beh.vior are needed to confirm th. results found in our study.
