青光眼是一种以进行性视盘变化和视野损失为特征的眼压相关性疾病。杯盘比在过去40a来都是评价视盘青光眼性改变的标准方法。然而我们却发现是一些小视盘的患者有典型青光眼性视野损失,而一些大视盘的患者却没有视野损失。杯盘比的检查效力和可重复性都低于一些新的检查方法。视盘损伤可能度分级(DDLS)是一种衡量视盘盘沿面积、并且校正了视盘大小等影响因素的新型视盘评价方法。DDLS也许是评价青光眼视盘的更为优化的方法。

Background： During sperm maturation, there is a reorganization of fatty acids from plasmatic membrane of the spermatozoa, which allows higher membrane integrity and acquisition of sperm motility. However, the fatty acid profile during sperm maturation remains unclear in dogs. Thus, the aim of this study was to identify the fatty acids from the epididymal spermatozoa and plasma during the sperm maturation, and observed changes in the motility and plasmatic membrane parameters. Twenty one adult dogs were used, subsequently to bilateral orchiectomy and epididymal storage, sperm samples were collected from the different segments of the epididymis. Samples were evaluated for conventional microscopy, computer-assisted motility analysis, sperm plasma membrane permeability and the fatty acid analysis（lipids were extracted, transmethylated and analyzed by chromatography）.Results： Caput and corpus sperm showed lower values for the motility variables evaluated and plasmatic membrane integrity, indicating different levels of the fatty acids organization. Saturated, monounsaturated and polyunsaturated fatty acids were in higher concentrations in the spermatozoa from epididymis cauda. Highlighting the presence of caprylic, stearic and docosahexaenoic ***： These findings demonstrate the influence of the fatty acid profile during sperm maturation, assigning physical and chemical changes in sperm cells, essential for fertilization.

We conducted a systematic review of the literature to determine the influence of different hysterectomy techniques in the sexual behavior of women who underwent. We searched CENTRAL (The Cochrane Library), PubMed, SCOPUS, CINAHL and LILACS for studies between the years 1998 and 2010 that prospectively examined the sexuality after hysterectomy. Those that were not randomized controlled clinical trials were excluded. It was not available electronically, it was not related with the outcomes determined, it was not research, but publications before 1998 and study which women realized chemotherapy and radiotherapy. From the 455 identified studies, 9 met inclusion criteria. There was variability in how hysterectomies influence in the sexual behavior. Most of studies considered women who underwent vaginal hysterectomy had fewer changes in sexual behavior. Sexual desire, intercourse frequency and orgasm are the sexual aspects reported by women as more changes experimented after surgery. Findings from this study have implications for healthcare providers and policymakers. Each woman needs an individualized care plan that fits within the context of her life, and there are basic interventions that every woman who underwent hysterectomy should receive. This review draws attention to the need for different care plans for women who underwent different hysterectomy techniques.

This paper analyzes the effect of partial sand replacement by sugarcane bagasse ash in mixed mortars utilizing a 1:2:9 mix proportion by volume for cement, lime and fine aggregate. The ash is characterized by its particle distribution, pozzolanic activity, chemical composition, bulk density, moisture content and loss on ignition. The mortars are then produced with a constant water/cement ratio of 2.64 and a partial replacement of sand with sugarcane bagasse ash using different substitution percentages (0%, 5%, 10%, 15% and 20%). The mortars are characterized in the plastic state: water retention, bulk density and air content, and in the hardened state: capillary coefficient, tensile strength by bending test, axial compressive strength and flexural and longitudinal Young’s modulus. The statistical analysis of the results showed that the ash can be incorporated into mortars without causing significant alterations in its properties.

Genetic engineering has created many genetically modified （GM） crop varieties that express the cry toxin from the bacterium Bacillus thuringiensis （Bt）. The cry toxin, synthesized during plant growth, has insecticidal properties, and can be expressed anywhere in the plant. This study aimed to ascertain the richness and species diversity of edaphic Formicidae and Coleoptera in GM cotton fields compared with the conventional non-transformed cotton crop. We analyzed data from commercial cotton fields located in the municipality of Maracaju, Mato Grosso do Sul, Brazil. The experiment was conducted during the reproductive period of cotton, employed two treatments： Bt cotton and non-Bt cotton. Samples were collected with pitfall traps. Formicidae species richness in the Bt area was lower than in the non-Bt area, but species composition did not differ between the two treatments. Species composition of Coleoptera communities also differed between the treatments because some species were more abundant in the Bt cotton area. On the other hand, the species richness of this group was similar in both areas.

AIMTo determine the long-term effects of selective laser trabeculoplasty (SLT) on intraocular pressure (IOP) and the number of medications used up to 5y following treatment in glaucoma patients receiving maximally tolerated medical therapy (MTMT).METHODSThe Wills Eye Hospital Glaucoma Research Center retrospectively reviewed the charts of glaucoma patients who underwent SLT after receiving MTMT. Eyes that did not achieve their target pressure within 3mo following SLT were excluded from the study. Changes in mean IOP and number of glaucoma medications used were analyzed at 1, 3, and 5y following ***-five eyes of 67 patients were included in the study. Fifteen eyes that received SLT failed to achieve their target pressure within 3mo and were excluded from the study. The average follow-up time was 37.4mo (±14.4). Mean IOP was significantly reduced 1y after treatment (P=0.005). It was also reduced 3, 5y after treatment without reaching statistical significance (P=0.20 and P=0.072, respectively). There was a significant decrease in mean number of medications used 1, 3, 5y after treatment (P<0.001, P<0.001, and P=0.039, respectively). In the span of 5y, 2 eyes (2.7%) underwent repeat SLT, 7 eyes (9.3%) underwent glaucoma surgery and an additional 3 eyes (4.0%) underwent *** significantly reduced the number of glaucoma medications used 5y following treatment in glaucoma patients receiving MTMT. SLT may delay operating-room surgery.

Neuropathic pain after spinal cord injury(SCI) is a complex condition that responds poorly to usual treatments. Cell transplantation represents a promising therapy;nevertheless, the ideal cell type in terms of neurogenic potential and effectiveness against pain remains largely controversial. Here, we evaluated the ability of fetal neural stem cells(fNSC) to relieve chronic pain and, secondarily, their effects on motor recovery. Adult Wistar rats with traumatic SCI were treated, 10 days after injury, with intra-spinal injections of culture medium(sham) or fNSCs extracted from telencephalic vesicles(TV group) or the ventral medulla(VM group) of E/14 embryos. Sensory(von Frey filaments and hot plate) and motor(the Basso, Beattie,Bresnahan locomotor rating scale and inclined plane test) assessments were performed during 8 weeks. Thereafter, spinal cords were processed for immunofluorescence and transplanted cells were quantified by stereology. The results showed improvement of thermal hyperalgesia in the TV and VM groups at 4 and 5 weeks after transplantation, respectively. Moreover, mechanical allodynia improved in both the TV and VM groups at 8 weeks. No significant motor recovery was observed in the TV or VM groups compared with sham. Stereological analyses showed that ~70% of TV and VM cells differentiated into NeuN+ neurons,with a high proportion of enkephalinergic and GABAergic cells in the TV group and enkephalinergic and serotoninergic cells in the VM group. Our study suggests that neuronal precursors from TV and VM, once implanted into the injured spinal cord, maturate into different neuronal subtypes, mainly GABAergic, serotoninergic, and enkephalinergic, and all subtypes alleviate pain, despite no significant motor recovery. The study was approved by the Animal Ethics Committee of the Medical School of the University of S?o Paulo(protocol number 033/14) on March 4, 2016.
