The bloodsucking bug Triatoma williami is the main vector of Trypanosoma cruzi, the etiological agent of Chagas disease in State of Mato Grosso, Brazil. It occurs in sylvatic areas of Brazilian savanna with often records of adult specimens in domestic and peridomestic habitats. We describe, for the first time, the reproductive parameters of T. williami females such as fecundity, fertility and lifespan. We also evaluate whether mating and nourishment status of females of T. williami may modulate the reproductive parameters. As a result, the presence of male corroborated to increase female lifespan from 5.14 ± 1,77 to 34.57 ± 10,86 weeks. The oviposition rate in mated female increased 275% when we compared to the fecundity values in unmated females. Finally, our results indicate that mating is crucial to improve lifespan and fecundity of T. williami females. This characteristic may be related to the environmental conditions under T. williami develops, because the sylvatic ecotopes form small scattered colonies with infrequent access to blood sources.

Cervical cancer (CC) is caused by persistent human papillomavirus (HPV) infection and affects women worldwide. The progression ofan HPV persistent infection to CC is influenced by genetic factors. Three single nucleotide polymorphisms (SNPs) in TP53, NQO1 andRPS19 genes (rs1042522, rs1800566, rs2305809, respectively) were previously associated with CC in European and North Americanpopulations. The present case-control study aimed to investigate the association of the SNPs rs1042522, rs1800566, and rs2305809with CC in an admixed population in southern Brazil. A total of 435 women (106 CC patients and 329 controls) were recruited forthis study. All women were interviewed and underwent clinical sampling. SNPs rs1042522 and rs1800566 were evaluated by PCR-RFLP. SNP rs2305809 was determined by real-time PCR. The crude and adjusted ORs with 95% CI were estimated. The recessive genetic model(C/C + C/T) for rs2305809 was more frequent in the control group (79.9%) compared to the cases (69.8%), being associated withCC protection (adjustedOR = 0.49; 95% CI: 0.27-0.90). However, the other polymorphisms evaluated did not present significant differencesbetween cases and controls. This study detected a protective association for the recessive genetic model in rs2305809. These resultssuggest a potential role of the RPS19 gene in CC.

Blooms of macroalgae have grown over the planet in recent decades as a possible result of eutrophication of coastal waters. Visually, a bloom forming can be identified by dominant presence of an organism at the expense of others. In mid-January 2014, a forming bloom of red algae was detected on the beach of Garopaba, Santa Catarina State, Brazil. This aroused the interest of tourists and locals as well as the scientific community. Thus, the objective of this study was to characterize and quantify the photosynthetic floating organisms contributing to this phenomenon. In addition, we qualitatively compared algal composition of the bloom to those deposited in the post-beach area and the adjacent rocky shore community. Five sampling points in random patches of floating material were defined. At each point, five replicates were taken with a cube of 32,768 cm3, resulting in a total of 25 samples. Samples were collected in the inner area enclosed by a PVC quadrate of about 900 cm2 from the shore and the specimens found in post-beach zone (wrack). Twenty-four taxa of macroalgae were found in the bloom, with Aglaothamnion uruguayense as the dominance one. Ten taxa were found on shore. Only four taxa were found in the post-beach area. The biomass estimated for A. uruguayense in the floating material was 8.35 tons with an estimated area of 52,770 m2. It is possible that this huge biomass value of the bloom is related to the local nutrient intake, and our results reinforce the necessity of coastal integrative management initiatives.

There are few studies which attest the efficacy of acupuncture on treatment of sleep disturbs in Parkinson disease. The aimed of this randomized clinical trial was to evaluate the effects of acupuncture on sleep disturbs of 22 patients with diagnosis of idiopathic Parkinson disease (Hoehn–Yahr 1 to 3) who have assistance on the Pro-Parkinson Program of Clinical Hospital at Federal University of Pernambuco in Brazil. All participants were evaluated by Parkinson Disease Sleep Scale (PDSS) before and after 8 weeks. The experimental group was submitted to 8 sections (once a week) which had duration of 30 minutes. The control group had no intervention. The intervention was executed using the acupuncture points LR3 (Taichong), SP6 (Sanyinjiao), LI4 (Hegu), TE5 (Wai-Guan), HT7 (Shenmen), PC6 (Neiguan), LI11 (Quchi), GB20 (Fengchi). Paired analyses were obtained by Wilcoxon test and independent analyses were made according to Mann–Whitney test. This study presented a potential therapeutic benefit of acupuncture on sleep disturbs of Parkinson's disease patients. This study showed a possible therapeutic benefit through acupuncture in sleep disorders in patients with PD. However, we propose new studies related to the effects of acupuncture on the clinical symptoms and evolution of the disease.

Malva sylvestris L. is widely used in medicine for treatment of inflammatory processes. The plant has antiinflammatory properties due to substances such as mucilage, flavonoids, and tannins. A mouthwash with leaves from the plant can be used for the treatment of wounds in the oral mucosa. The aim of this study was to assess the wound healing effect of Malva sylvestris L. on a palate mucosa wound in rats. After intraperitoneal anesthesia, a 4-mm-diameter excisional wound was made in the center of the palatal mucosa of 136 rats, using a punch-out biopsy tool. Eight animals were used as baseline wound. The remaining rats were divided into four groups: CO, control; OB, orabase vehicle; CX, 2% chlorhexidine; and MA, 20% Malva in orabase. At 24 h postoperatively, the animals were immobilized without anesthetic to apply 25 mg of each substance twice a day, totaling 50 mg daily. The wound areas were measured photographically and the reepithelialization rates were determined histologically (%) after 0, 3, 7, 15, and 21 days. The data were analyzed by ANOVA and Tukey post hoc test. Similar healing pattern was observed among the groups (P > .05; ANOVA). According to the methodology, Malva sylvestris L. extract had no effect on wound healing in the palatal mucosa of rats.

Objective: Twenty-four pregnant Nellore primiparous grazing cows were used to evaluate the effects of energy-protein supplementation and supplementation frequency during pre (105 d before calving) and postpartum (105 d after calving) on performance and metabolic characteristics. Methods: Experimental treatments consisted of a control (no supplementation), daily supplementation (1.5 kg/d of concentrate/animal) and infrequent supplementation (4.5 kg of concentrate/ animal every three days). During the pre and postpartum periods, concentrations of blood metabolites and animal performance were evaluated. Ureagenesis and energy metabolism markers were evaluated at prepartum period. Results: Supplementation frequency did not alter (p>0.10) body weight (BW), average daily gain (ADG), and carcass traits during pre and postpartum. The BW (p = 0.079), adjusted BW at day of parturition (p = 0.078), and ADG (p = 0.074) were greater for supplemented cows during the prepartum. The body condition score (BCS; p = 0.251), and carcass traits (p>0.10) were not affected by supplementation during prepartum. On postpartum, supplementation did not affect animal performance and carcass traits (p>0.10). The dry mater intake was not affected (p>0.10) by supplementation and supplementation frequency throughout the experimental period. Daily supplemented animals had greater (p<0.001) glucose levels than animals supplemented every three days. Supplementation and supplementation frequency did not alter (p>0.10) the levels of blood metabolites, neither the abundance of ureagenesis nor energy metabolism markers. Conclusion: In summary, our data show that the reduction of supplementation frequency does not cause negative impacts on performance and metabolic characteristics of primiparous grazing cows during the prepartum.

Objectives: The aim of this in vitro study was to evaluate the microhardness and surface roughness of composite resins before and after tooth bleaching procedures. Materials and Methods: Sixty specimens were prepared of each composite resin (Filtek Supreme XT and Opallis), and BisCover LV surface sealant was applied to half of the specimens. Thirty enamel samples were obtained from the buccal and lingual surfaces of human molars for use as the control group. The surface roughness and microhardness were measured before and after bleaching procedures with 35% hydrogen peroxide or 16% carbamide (n = 10). Data were analyzed using 1-way analysis of variance and the Fisher test (α = 0.05). Results: Neither hydrogen peroxide nor carbamide peroxide treatment significantly altered the hardness of the composite resins, regardless of surface sealant application; however, both treatments significantly decreased the hardness of the tooth samples (p < 0.05). The bleaching did not cause any change in surface roughness, with the exception of the unsealed Opallis composite resin and dental enamel, both of which displayed an increase in surface roughness after bleaching with carbamide peroxide (p < 0.05). Conclusions: The microhardness and surface roughness of enamel and Opallis composite resin were influenced by bleaching procedures.
