Reação de híbridos, linhagens e progênies de pimentão à requeima causada por Phytophthora capsici e ao mosaico amarelo causado por Pepper yellow mosaic vírus (PepYMV)

Resistance to pepper blight induced by Phytophthora capsici and to yellow mosaic caused by a potyvirus species (PepYMV) are two priorities of most pepper (Capsicum annuum L.) breeding programmes in Brazil. The reactions of three commercial hybrids (Magali-R, Atenas F1, and Fortuna Super F1) to both P. capsici and PepYMV was studied, along with those of 20 experimental hybrids, 6 inbred lines and two F2:4 progenies from the Universidade Federal of Lavras pepper breeding programme. Trials in randomized complete block designs were carried out independently for each of the pathogens, with four and two replications, respectively. Each replications comprised 8 plants in 128-cell speeding styrofoam trays, kept in plastic-covered greenhouses protected with screen at the sides. Evaluation of symptoms was made from the 4th to the 14th and from the 15 th to the 40th day after inoculation (DAI) for P. capsici and PepYMV, respectively. Inoculation with P. capsici was made by dispensing 5mL of a 104 zoospore.mL-1 solution at the soil around the base of each plant. PepYMV was mechanically inoculated from extracts of previously infected leaves of TNN tobacco. Hybrids Magali-R and Fortuna Super were susceptible to P. capsici, while the hybrid Atenas, the access Criollo de Morellos 334, the progeny PIX-030 pl#03-2 and PIX-030 pl#06-3 (both originated from crosses with Criollo de Morellos), and the line PIM-013 were resistant. Among the experimental hybrids, three were also resistant to P. capsici, all three having PIM-013 as one of the parental lines. Resistance to PepYMV was found in Criollo de Morellos 334, progeny PIX-030 pl#03-2 and PIX-030 pl#06-3, and in the commercial hybrid Magali, besides 6 other experimental hybrids having line MYR-29 as one of the parental ines. The only treatment with resistance to both P. capsici and PepYMV were families PIX-030 pl#03-2 and PIX-030 pl#06-3, and the experimental hybrid F1(PIM-013 x MYR-29). Progeny PIX-030 pl#03-2 and PIX-030 pl#06-3 proved to be promissing sources of resistance to both pathogens to be deployed in breeding programmes. PIM-013 and MYR-29 are promissing sources of resistance to P. capsici and PepYMV, respectively, to be deployed in development of hybrids with resistance to these pathogens.
Ultrasound guided injection of platelet enriched plasma versus corticosteroids in patients suffering rotator cuff tendinopathy

Shoulder pain is the third most common musculoskeletal complaint. Rotator cuff tendinopathy is an overuse condition that manifests itself as pain in and around tendon and happens when the body fails to regenerate properly. This painful condition is associated with tendon disorganization and thickening that reduces its physical properties, which causes the tendon to fatigue, further exacerbating the painful condition with ultimate failure. A lot of trials and modalities of treatment are studied to avoid the surgical choice such as physiotherapy, NSAIDs and/or ESWT. Local injection of shoulder joint is widely used and studied but the diversity of results lead us to establish further studies. The purpose of my study is to compare between two important modalities in non-surgical treatment of supraspinatus tendinopathy. This study was conducted on 40 patients divided into two groups: group 1 received 3 subacromial injections of platelet rich plasma 10 days interval and group 2 received single subacromial injection of corticosteroid, both are ultrasound guided. Clinical examination using Constant Score is used to evaluate the patients before receiving treatment (0), one month (1) and six months (6) after receiving the treatment. We can conclude the results of the 2 groups as there is high significant improvement of the 2 groups comparing base line start. However Corticosteroids shows earlier improvement than PRP after 1 month follow up, but at the end of follow up (6 ms) PRP shows significant improvements according to Constant-Murley Score. According to group 1 there was no complications reported except a discomfort in shoulder region 24 hrs post injection up to 3 days maximum. While in group 2 there was no complications reported all through the 6 months follow up. Ultrasound subacromial injection of corticosteroid and PRP achieved significant improvement in pain and function of shoulder joint in RCTs. Corticosteroid achieved better improvements according to Constant-Murley Score in short term follow up (4 weeks) than PRP group, while PRP achieved higher significant improvements than corticosteroid in pain and function of the joint after 6 months follow up as corticosteroid group showed decline in the pain and function results after 6 months follow up.
Evaluation of the Prognostic value of the Prechemotherapy Platelet to Lymphocyte Ratio in Malignant Pleural Mesothelioma

The prognostic value of Platelet-to-lymphocyte ratio (PLR) in patients with malignant pleural mesothelioma is still indistinct. We conducted this study to assess the prognostic significance of pretreatment PLR in patients with MPM. to assess the prognostic significance of pre-treatment PLR in patients with MPM. we retrospectively reviewed 1! 0 patients treated for MPM with chemotherapy in Ain-Shams University hospital, Clinical Oncology department between January 2013 and December 2017. Pre-treatment CBC was available for the 110 patients to calculate PLR by dividing the absolute platelet count by the absolute lymphocytic count. Out of 110 patients with available pre-treatment complete blood picture, population age ranged from 28 to 70 years. Male to female ratio was 5:6 . Epithelioid subtype represent 85% of cases. Stages III and IV present 48.2% and 35.5, respectively while stages I and II present 3.6% and 12.7%, respectively. The median PLR in the study population was found to be 177.9, PLR is an easy , reproducible and inexpensive prognostic factor that needs to be more investigated in MPM.
Comparative study of the structure of TvNPV polyhedrin and TvNPV virion protein by Raman spectroscopy

Raman spectra were obtained and analysed for polyhedrin and virion protein of Trabala vishnou nuclear polyhedrosis virus (TvNPV-P and TvNPV-VP, respectively). It was found that the secondary structures of the protein of the two samples differ: the protein of TvNPV-P has predominantly an α-helical and β-sheet structure whereas that of TvNPV-P contains predominantly a β-sheet content, with an α-helix content and a lower random-coil or β-turn content. All tyrosyl residues in the protein of TvNPV-P are exposed, whereas 80% of the tyrosyl residues are exposed and 20% are buried in the protein of TvNPV-VP. The majority of the tryptophan residues in the protein of TvNPV-VP are in a hydrophobic environment. The TvNPV-VP has a trans-gauche-trans configuration of the CCSSCC linkage.
Foliar uptake of water by wet leaves of Sloanea woollsii, an Australian subtropical rainforest tree

At leaf water potentials (ψ) of around -2.5 MPa, detached leaves of Sloanea woollsii F.Muell. , an Australian subtropical rainforest tree, were able to absorb small amounts of water vapour from a saturated atmosphere, but absorbed considerably more liquid water if their surfaces remained wet. When leaves attached to small branches exhibiting a ψ of -2 MPa were sprayed with water and maintained in a saturated atmosphere, leaf ψ returned to saturation values within about 6 h. In a further experiment, a ψ of -2 MPa was imposed on detached, forked branches. Branches were then exposed to a saturated atmosphere and leaves on one half of the fork were kept wet whilst the rest remained dry. Leaf ψ was measured periodically for both dry and wet leaves and in both cases was found to increase with time. This indicated that leaf surface water was imbibed by wet leaves and transported into the branch resulting in alleviation of low water potentials in the dry leaves. In the submontane rainforests in which S. woollsii occurs, extended periods with little or no rainfall occur regularly. Throughout the year, foliage is wet by fog or dew alone for about 25% of the time. It is suggested that the presence of leaf surface water during rainless periods when leaf Psi is low may be important for the survival of S. woollsii. The actual mechanism of foliar absorption is uncertain, but is likely to be direct imbibition through the cuticle.
Uptake and Assimilation of Nitrate and Iron in Cultivated and Wild Vaccinium Species

Growth of cultivated Vaccinium species on soils with a pH above 6.0 is inhibited and production can be extended to these types of soils only after extensive soil modifications. V. arboreum is a wild species that grows on soils with higher pH values. The aim of the present study was to characterize differences in nitrate and iron assimilation in cultivated vs. wild Vaccinium. Genotypes from V. corymbosum and V. arboreum were grown hydroponically with different nitrate and iron concentrations. Nitrate and iron uptake were significantly greater in V. arboreum compared with V. corymbosum. This was correlated with increased nitrate reductase and ferric chelate reductase activities and increased tissue concentrations of reduced nitrogen and iron in V. arboreum. The wild species, V. arboreum, clearly exhibits an increased ability to assimilate nitrate and iron compared with V. corymbosum. This greater capacity for assimilation may play a significant role in this species' broader soil adaptation.
Plant Growth Regulator and Mowing Height Effects on Seasonal Root Growth of Penncross Creeping Bentgrass

Summer decline of creeping bentgrass [Agrostis palustris Huds. (=Agrostis stolonifera var. palustris (Huds.) Farw. ] root growth is an annual concern in many regions of the USA. A 2-yr field study was conducted to investigate the effects of mowing height and plant growth regulator (PGR) treatments on root biomass (RB) patterns in Penncross' creeping bentgrass, grown on a Wakulla sand (sandy, siliceous, Thermic Psammentic Hapludults) with 94% sand, 4% silt, 2% clay, 24 mg g -1 organic matter, and a pH of 6.1. Plots were maintained at 3.2, 4.0, or 4.8 mm throughout the experiment. Plant growth regulator treatments were trinexapac-ethyl, [4-(cyclopropyl-α-hydroxymethylene)-3,5-dioxo-cyclohexane carboxylic acid ethyl ester] applied at 0.05 kg a.i. ha -1 and paclobutrazol, {(±)-(R * ,R * )-β-[(4-chloro-phenyl) methyl]-α-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol} applied at 0.14, 0.28, or 0.56 kg a.i. ha -1 . Plant growth regulator treatments initially were applied in April 1997 and were reapplied monthly for 24 mo. Annual variation in air and soil temperature accounted for variable RB across years. Root biomass declined 76% from a May maximum to a minimum in September; however, RB increased between September and January. Turf mowed to a height of 3.2 mm consistently had lower RB than turf maintained at 4.0 or 4.8 mm, and had slower early autumn RB recovery. When averaged across mowing heights, only paclobutrazol (0.56 kg a.i. ha -1 ) reduced RB and no PGR increased rooting when compared with nontreated turf. From September to January of each year, a PGR by mowing height interaction showed that paclobutrazol applied at 0.56 kg a.i. ha -1 delayed RB recovery in turf mowed to a height of 4.8 mm, while no PGR delayed RB recovery in turf maintained at the 3.2 mm mowing height. Slower RB recovery in turf mowed to 3.2 mm following the September minimum RB was attributed to reductions in turf quality and density, rather than the effects of PGRs. Paclobutrazol only reduced Penncross RB when applied at twice the labeled rate and with greater application frequency than is typical for most PGR use patterns. These results showed that labeled rates of paclobutrazol and trinexapac-ethyl did not adversely affect root growth under putting green conditions.
Quantitative detection of chlorophyll in cyanobacterial blooms by satellite remote sensing

The extent of cyanobacterial blooms has been mapped using different satellite sensors from weather satellites to synthetic aperture radars. Quantitative detection of chlorophyll in cyanobacterial blooms by remote sensing, however, has been less successful. The first civilian hyperspectral sensor in space, Hyperion, acquired an image of cyanobacterial bloom in the western part of the Gulf of Finland on 14 July 2002. A chlorophyll concentration map was produced from this image using a spectral library that was created by running a bio‐optical model with variable concentrations of chlorophyll. The results show that chlorophyll concentrations in the bloom area were much higher than reported by conventional water‐monitoring programs, ships‐of‐opportunity, and satellite measurements. The reason why both in situ and satellite methods underestimate the amount of phytoplankton during cyanobacterial blooms is vertical and horizontal distribution of cyanobacteria, because cyanobacteria can regulate their buoyancy and are not uniformly distributed within the top mixed layer of water column in calm weather conditions. Aggregations of cyanobacteria form dense subsurface blooms and surface scums during extensive blooms. This study demonstrates that it is difficult to collect representative water samples from research vessels using standard methods because ships and water samplers destroy the natural distribution of cyanobacteria in the sampling process. Flowthrough systems take water samples from the depths at which the concentration of cyanobacteria is not correlated with the amount of phytoplankton that remote sensing instruments detect. The chlorophyll estimation accuracy in cyanobacterial blooms by many satellites is limited because of spatial resolution, as significant changes in chlorophyll concentration occur even at a smaller spatial scale than 30 m.

Vol. VII, Ano 2020, No. 1 (Janeiro Abril) contexts need to reveal more and more the formative potential of the dialogicreflexive practice of the actors in the educational process, in this sense a case study is presented based on the reality presented in 4 graduate students belonging to the context University in Lima-Peru. The content analysis of these students' reflective logbooks was carried out, which demonstrated how reflection is arranged in the so-called “reflective dialogues”. Strategy that implied orienting the reflection with oneself and with others (in an intra and inter-reflexive dialogic practice), as well as awareness in the recognition of the researcher's paradigmatic axis. These aspects are configured in articulating axes that enable the researcher to construct the scientific text, from the configuration of his own dialogic-reflexive posture.
Comparison of Early Maladaptive Schemas and Cognitive Emotion Regulation Strategies between Obese and Normal Weight Women

Introduction: Over the past years, due to the lifestyle modifications, obesity has widely been recognized as a major public health problem which affects societies worldwide. Recently, evidences have shown that early maladaptive schemas are strongly associated with eating psychopathology. Therefore, the present study aimed to investigate the differences in early maladaptive schemas and cognitive emotion regulation strategies between obese women and matched normal weight controls. Methods: This research is a comparative (analytical), case control study. The cases were 110 obese women selected by random sampling method among those women who referred to Farhangian clinic in Kashan city. The same number of subjects with normal weight has also been considered as controls. Data was collected by the use of standard instruments: questionnaires of early maladaptive schemas questionarie (Young, 1999), and cognitive emotion regulation strategies questionarie (Garnefski & Kraaij, 2001). The data were analyzed by t-test and SPSS 22 statistical method. Results: Based on the results, obese women experienced significantly more severe emotional deprivation, distrust/ misbehavior, and social isolation. Furthermore, adaptive and maladaptive strategies in cognitive emotion regulation were significantly different between obese and normal weight women. Conclusions: According to the results, both early maladaptive schemas and deficits in cognitive emotion regulation may potentially play roles in psychopathology of obesity. These findings suggest that applying interventions on early maladaptive schemas and adaptive emotion regulation strategies could be beneficial in obesity treatment.
Histopathological Patterns of Gastric Mucosal Biopsies in Dyspepsia – A Study of 550 Cases

Objective: Dyspepsia is a common condition which is seen in the medical outpatient department. Helicobacter pylori is the causal agent in most of the cases of gastritis and peptic ulceration. This is a retrospective study aimed to study the histological patterns in gastric biopsy from patients with complaints of dyspepsia. Methods: In this study, a total of 550 biopsy samples from patients with a clinical history of dyspepsia which were received at the department of histopathology were analyzed. The biopsy samples were procured in Bouin’s fixative and were paraffin embedded. Sections were taken and stained with hematoxylin and eosin. May-Grunwald-Giemsa stain was used to visualize H. pylori. Alcian blue stain was used to identify intestinal metaplasia. Results: It was observed that 194 (35.2%) cases showed features of chronic gastritis without H. pylori infection. H. pylor i was noted in a total of 296 cases (53.8%) among which 256 cases (46.5%) showed features of chronic gastritis, 28 cases (5.09%) showed active gastritis, and 12 cases (2.2%) showed features of chronic gastritis with intestinal metaplasia. Conclusion: Chronic gastritis is a common condition worldwide. Chronic infection with H. pylori accounts for the majority of cases of chronic gastritis.
In vitro production of zygote from slaughterhouse driven buffalo oocyte

Buffalo is a highly potential animal species in terms of milk and meat production but traditionally they are regarded as poor breeder. In vitro embryos production technology has been introduced in many countries to improve reproductive efficiency of buffalo. Considering the above fact, the present study was undertaken aiming to produce in vitro buffalo embryo in the laboratory. Ovaries of slaughtered buffaloes were collected from abattoir and transported to the laboratory within 4 to 5 hr of slaughter. Cumulusoocyte-complexes (COCs) possessing an even cytoplasm and covered with minimum 3 layers of compact cumulus cells was selected for in vitro maturation (IVM) for 24 hr (5% CO2 in air at 38.5°C with maximum humidity). After IVM, the presumptive matured COCs were co-cultured with capacitated fresh spermatozoa for 18 hr After IVF, the presumptive zygote were denuded, washed and transferred in to in vitro culture medium (IVC 1) for 3 days. After three days cleavage were recorded and 4 cell embryos were transferred in to in vitro culture media II for next 2 days. The development of embryos was evaluated on day 6. A total of 227 buffalo ovaries were collected from the slaughterhouse and categorized into 2 groups based on presence (n=83) or absence (n=144) of corpus luteum (CL). A total of 1464 follicles were counted on the ovarian surface, 1066 being from CL absent and 398 from CL-containing ovaries. A significantly higher (P<0.01) number of follicles, aspirated follicles, normal COCs and total COCs (7.4 ± 0.21, 5 ± 0.00, 1.98 ± 0.77 and 2.98 ± 0.16 respectively) were observed in CL-absent ovaries than those aspirated from CL-containing ovaries (4.80 ± 0.17, 3.92 ± 0.95, 0.88 ± 0.60 and 1.88 ± 0.16 respectively). Total 358 normal COCs were set for in vitro maturation and underwent for IVF and IVC. Results showed that cleavage rates were 56.42%. Among the cleaved embryos, 137 were at 2-cell stage and 65 were at 4-cell stage. Therefore, development rate to 2 cell and 4-cell stage was 38.27% and 18.15% respectively. No embryo developed beyond 4-cell stage. This result indicates that follicle and oocyte numbers and oocyte quality are associated with CL of ovaries and current culture system support in vitro embryo production upto 4-cell stage. The in vitro culture condition may be improved for increasing efficiency of embryo production. (
Preliminary Study of Calcium Homeostasis Modulator 1 Involvement in Trigeminal Neuralgia

This study was to observe the changes in the expression of calcium homeostasis modulator 1 in trigeminal nucleus of trigeminal neuralgia rats with the infraorbital nerve-chronic constrictive nerve injury and to explore the role of calcium homeostasis modulator 1 in trigeminal neuralgia. Thirty Sprague Dawley rats were randomly assigned to 5 groups, control group, sham group, infraorbital nerve-chronic constrictive nerve injury group, ruthenium red group and normal saline group, with 6 rats in each group. All experimental rats were tested for pain behavior 1 d before surgery, 1, 3, 5, 7, 9, 11 and 14 d after surgery, including the mechanical pain threshold of Von Frey filament in the trigeminal innervated skin area and number of faces captured in video recording. The expression of calcium homeostasis modulator 1 in the trigeminal spinal nucleus was detected on d 15 after surgery in all experimental groups. The expression of calcium homeostasis modulator 1 in the trigeminal spinal nucleus of the infraorbital nerve-chronic constrictive nerve injury group was significantly higher than that of the control and the sham group on the 3rd and 15th d after modeling. Intraperitoneal injection of ruthenium red, a calcium homeostasis modulator 1 inhibitor, increased the mechanical pain threshold of infraorbital nerve-chronic constrictive nerve injury rats and significantly reduced the number of scratches, but did not change the expression of calcium homeostasis modulator 1 in the trigeminal spinal nucleus. In conclusion, the expression of calcium homeostasis modulator 1 protein in the trigeminal spinal nucleus is involved in the central sensitization of trigeminal neuralgia pain. Moreover, the hyperalgesia can be improved by using calcium homeostasis modulator 1 inhibitor without affecting the calcium homeostasis modulator 1 expression.
Hydrolysis of iodothyronine glucuronides by obligately anaerobic bacteria isolated from human faecal flora

35 bacterial strains isolated from the human faecal flora were screened for hydrolysis of the glucuronides of 3,3′,5-triiodothyronine and 3,3′-diiodothyronine. Two Gram-positive obligately anaerobic strains possessed glucuronidase activity. These strains probably belong to the genus Eubacterium, but ethanol was produced in high concentrations during glucose fermentation, which makes final classification difficult. Considering the number of bacteria in the intestinal flora (> 108/ml) and the biliary excretion of iodothyronine conjugates, the strains must be able to hydrolyse a major part of the total daily intestinal supply of these iodothyronine metabolites. The study extends previous observations with faecal suspensions of human and rat origin [24]. The relevance of bacterial β-glucuronidase activity for a possible enterohepatic circulation of iodothyronines is discussed.
