Retinal and optic nerve diseases are degenerative ocular pathologies which lead to irreversible visual loss. Since the advanced therapies availability, cell-based therapies offer a new all-encompassing approach. Advances in the knowledge of neuroprotection, immunomodulation and regenerative properties of mesenchymal stem cells(MSCs) have been obtained by several preclinical studies of various neurodegenerative diseases. It has provided the opportunity to perform the translation of this knowledge to prospective treatment approaches for clinical practice. Since 2008, several first steps projecting new treatment approaches, have been taken regarding the use of cell therapy in patients with neurodegenerative pathologies of optic nerve and retina. Most of the clinical trials using MSCs are in Ⅰ/Ⅱ phase, recruiting patients or ongoing, and they have as main objective the safety assessment of MSCs using various routes of administration. However, it is important to recognize that, there is still a long way to go to reach clinical trials phase Ⅲ-Ⅳ. Hence, it is necessary to continue preclinical and clinical studies to improve this new therapeutic tool. This paper reviews the latest progress of MSCs in human clinical trials for retinal and optic nerve diseases.

Bacterial vaginosis:a synthesis of the literature on etiology,prevalence,risk factors,and relationship with chlamydia and gonorrhea infections

Bacterial vaginosis(BV) is a common vaginal disorder in women of reproductive age. Since the initial work of Leopoldo in 1953 and Gardner and Dukes in 1955, researchers have not been able to identify the causative etiologic agent of BV. There is increasing evidence, however, that BV occurs when Lactobacillus spp., the predominant species in healthy vaginal flora, are replaced by anaerobic bacteria, such as Gardenella vaginalis, Mobiluncus curtisii, M. mulieris, other anaerobic bacteria and/or Mycoplasma hominis. Worldwide, it estimated that 20%–30% of women of reproductive age attending sexually transmitted infection(STI) clinics suffer from BV, and that its prevalence can be as high as 50%–60% in high-risk populations(e.g., those who practice commercial sex work(CSW). Epidemiological data show that women are more likely to report BV if they: 1) have had a higher number of lifetime sexual partners; 2) are unmarried; 3) have engaged in their first intercourse at a younger age; 4) have engaged in CSW, and 5) practice regular douching. In the past decade, several studies have provided evidence on the contribution of sexual activity to BV. However, it is difficult to state that BV is a STI without being able to identify the etiologic agent. BV has also emerged as a public health problem due to its association with other STIs, including: human immunodeficiency virus(HIV), herpes simplex virus type 2(HSV-2), Chlamydia trachomatis(CT) and Neisseria gonorrhoeae(NG). The most recent evidence on the association between BV and CT/NG infection comes from two secondary analyses of cohort data conducted among women attending STI clinics. Based on these studies, women with BV had a 1.8 and 1.9-fold increased risk for NG and CT infection, respectively. Taken together, BV is likely a risk factor or at least an important contributor to subsequent NG or CT infection in high-risk women. Additional research is required to determine whether this association is also present in other low-r

AIM To determine a potential relationship between serum undercarboxylated(uc OC) concentration and cardiovascular risk factors in type 2 diabetes(T2D) patients and healthy subjects(HS).METHODS A cross-sectional study was conducted on 140 subjects classified into two groups, 70 with T2D and 70 HS. Medical history and physical examination with anthropometric measurements were obtained from all subjects. Body fat percentage was determined by bioelectrical impendency analysis. Serum uc OC concentration was determined by enzyme immunoassay,while serum levels of insulin and hsC RP were obtained using high sensitivity enzyme-linked immunosorbent assay. Insulin resistance was determined using the homeostasis model assessment-IR. Lipid profile [triglycerides,total cholesterol(TC), high-density lipoproteins(HDL-c),low density lipoproteins(LDL-c), very low-density lipoproteins] was determined by spectrophotometry and standard formulas when applicable. RESULTS The T2D patient group showed significantly higher values of waist circumference, waist-to-hip ratio, systolic blood pressure(SBP), diastolic blood pressure(DBP),current smoking, and alcohol use when compared to the HS group(P < 0.05). We observed a significantly lower serum ucO C concentration in T2D than in HS(1.5 ± 1.4vs 2.3 ± 1.8, P < 0.05). In the whole study population,ucO C concentration was inversely correlated with body mass index(BMI)(r =-0.236, P < 0.05), fasting plasma glucose(r =-0.283, P < 0.01) and HDL-c(r =-0.255,P < 0.05); and positively correlated with LDL-c/HDL-c ratio(r = 0.306, P < 0.05) and TC/HDL-c ratio(r =0.284, P < 0.05). In the T2D group, serum uc OC concentration was inversely correlated with BMI(r =-0.310, P < 0.05) and body-fat percentage(r =-0.311,P < 0.05), and positively correlated with DBP(r = 0.450,P < 0.01). In HS group a positive correlation between serum levels of uc OC and SBP(r = 0.277, P < 0.05)was observed. CONCLUSION Serum uc OC is a potential marker for cardiovascular risk in Mex

Journal of Agricultural Science and Technology(A) 2016年第1期6卷 59-63页

作者： Amalia Cabrera Nunez Iliana Del Carmen Daniel Renteria Miguel Angel Lammoglia Villagomez Cesar Enrique Martinez sanchez sara Aida Alarcon Pulido Rebeca Rojas-Ronquillo School of Biological and Agricultural Science University of Veracruz Tuxpan Veracruz 92860 Mexico

The aim of this study was to evaluate the feed consumption and weight gain in calves fed with a nutritional block made of white mulberry （Morus alba） for a 90-day-period, involving dry season months （March-May） in Tuxpan, Veracruz, Mexico. A total of 45 growing Zebu x Swiss calves with an average weight of 200 kg were assigned randomly in three groups of 15 animals, and the following treatments of nutritional block were offered to each group： grazing animals （To）, grazing animals plus nutritious block with white mulberry （T1）, and grazing animals plus nutritious block without white mulberry （T2）. A consumption of 0.545 kg/d from block in treatment T1 was observed, significantly improving calves growing and showing a weight gain of 0.933 kg/d. Use of white mulberry in nutritional blocks is a good alternative for growing calves, as a feeding strategy given the seasonality of pasture production in the tropics.

对城镇化、城镇地区和碳循环相关的独立研究，加深了我们对能源和土地使用影响碳循环这一过程的认识。文章将多样化观点综合在一起，作为全面理解城镇化过程、城镇地区及其与碳循环关系的第一步。文章建议，对于不同的城镇化过程、机理和要素，不同的时间、不同的城市乃至跨城市的碳排放时空模式问题，需要在现有研究方法的基础上，应用补充和整合的新型跨学科研究法进行研究。文章呼吁对城镇化和不同位置城市碳影响的研究需要采用更加整体性的方法，其中既包括收入，也包括城市发展路径的其他相互联系的特性，如城市形态、经济功能和制度或治理安排。文章进一步指出城镇化机理和城镇化过程都存在广泛的不确定性，而且两者都与城市社会制度和建成环境系统存在相互关系，它们三者对碳循环均有影响，并且相关碳排量的控制又会对城镇化产生影响。最后，文章还研究了低碳城市转型发展的路径、障碍和局限，建议发展终端到终端、合作、综合的科学意识，从而提高城市转型效率，同时规避转型过程中的障碍。
