Published: November 2013

Symplocos dasyphylla Brand is one of the most poorly known species of Symplocos occurring in Rio de Janeiro. This species has been erroneously considered a synonym of S. itatiaiae Wawra, and the original description of S. dasyphylla does not contain the characters needed to diagnose the species. Here we provide a revised augmented description of S. dasyphylla, lectotypification, illustration, citations of material examined, data for assessing its conservation status, and a key to the species of Symplocos section Hopea occurring in Rio de Janeiro.

Authors: Farrell Derek , Keenan Paul , Knibbs Lorraine , Hicks Carolyn
Published: November 2013

This article is an evaluation of eye movement desensitization and reprocessing (EMDR) Europe Humanitarian Assistance Program (HAP) facilitators’ training in Pakistan based on a project set up in the aftermath of the 2005 earthquake. Q-methodology was the method of choice for this research because it permits the systematic study of subjective experiences by combining the richness of qualitative protocols with the rigors of quantitative ones. Research participants were 6 recently trained EMDR Pakistan consultants and facilitators, of which 5 were consultant psychiatrists and 1 was a general practitioner (GP)/psychologist. The Q concourse addressed issues such as EMDR clinical practice, cultural application of EMDR in Pakistan, EMDR research and development, and their experiences of their EMDR-HAP training. Results highlighted issues around professional role and application of EMDR, the teaching and learning experience of EMDR, clinical supervision, the importance of the therapeutic relationship, and the cultural sensitivity and application of EMDR in Pakistan. The article also considers how the EMDR-HAP training program could be improved in Pakistan.

Published: November 2013

A significant proportion of clients with psychosis have experienced childhood trauma and suffer from comorbid posttraumatic stress disorder. Research indicates that exposure to distressing early life events plays an important role in the emergence and persistence of psychotic symptoms—either directly or indirectly. The Two Method Approach of EMDR conceptualization and recent findings on reprocessing of psychosis-related imagery fit with the existing cognitive models of psychosis. This article presents a series of preliminary guidelines for conceptualizing EMDR treatment in psychosis, which are based on both theory and clinical experience and are illustrated with case examples. Several obstacles and related treatment strategies for using EMDR in psychosis are described. EMDR in psychosis can very well be combined with other standard interventions such as psychotropic medication and cognitive behavioral therapy.
Is EMDR an Evidenced-Based Treatment for Depression? A Review of the Literature
Authors: Wood Emily , Ricketts Thomas
Published: November 2013

It is not unusual for proponents of eye movement desensitization and reprocessing (EMDR) to claim it can be used to treat many mental health problems. Depression is an illness that affects the lives of millions across the world; the costs are high, economically and socially, and depression can be devastating for the individual. Despite this, depression is not well treated, so a desire to find other treatments is admirable. However, these treatments must be evidence based and although there is some evidence that EMDR may be a promising new approach, it cannot currently be described as an evidenced-based treatment for depression. There are studies under way across Europe that may produce the evidence needed to expand the recommendations for using EMDR with more than just posttraumatic stress disorder (PTSD).
Evaluation of Systemic Levels of Neutrophilic Enzymes in Patients With Hypertension and Chronic Periodontitis
Authors: Türkoğlu Oya , Barış Nezihi , Tervahartiala Taina , Şenarslan Ömer , Sorsa Timo , Atilla Gül
Published: November 2013

Background: Inflammation stimulates neutrophils to release their enzymes into the extracellular matrix. The aim of the present study is to investigate the serum levels of matrix metalloproteinase (MMP)‐8, MMP‐9, tissue inhibitor of MMP (TIMP)‐1, myeloperoxidase (MPO), and neutrophil elastase (NE) in patients with hypertension and chronic periodontitis (CP).

Methods: A total of 95 patients were included in the study. Patients were categorized into three groups: healthy control (n = 29), hypertensive control (n = 32), and hypertensive CP (n = 34). Periodontal parameters were recorded, and serum samples were collected from each participant. Serum MMP‐8, MMP‐9, TIMP‐1, MPO, and NE levels in circulation were assessed by enzyme‐linked immunosorbent assay.

Results: The hypertensive CP group had significantly higher serum MMP‐8, MMP‐9, and NE levels than the healthy control group (P <0.05). All study groups had similar serum TIMP‐1 levels (P >0.05). Significantly higher serum MPO levels were detected in patients with hypertension and CP than healthy controls and hypertensive controls (P <0.05); however, the difference in serum MPO levels was not significant between the healthy controls and hypertensive controls (P >0.05). There was no significant difference in MMP‐8/TIMP‐1 ratio among the study groups (P >0.05). MMP‐9/TIMP‐1 ratio was significantly higher in patients with hypertension and CP than healthy controls (P <0.05).

Conclusions: The presence of hypertension along with CP has a considerable effect on serum neutrophilic enzyme levels, except TIMP‐1. However, the levels of these enzymes do not seem to be affected by the presence of hypertension only. Further studies including patients who have only CP might help illuminate the effect of CP on these enzymes in patients with hypertension.

Published: November 2013

Background: Chronic periodontitis (CP) is a continuous, reversible source of inflammation with a potential impact on mortality in patients undergoing hemodialysis (HD). This study investigates the impact of oral health indicators, CP, and its treatment on survival rates in a group of patients undergoing HD.

Methods: Clinically stable patients undergoing HD were referred for a dental examination. All patients were prospectively followed in the dialysis clinic, and all‐cause mortality was recorded. Three groups of patients were analyzed: those who received CP treatment, those who did not, and patients without CP as a control group.

Results: A total of 122 patients (79 males and 43 females, aged 23 to 77 years; mean age: 50 years; range: 23 to 77 years) were enrolled. Forty percent reported having rarely been evaluated by a dentist, and 59% had CP. There were 34 fatal events during a mean follow‐up time of 64.1 ± 11.2 months. Oral factors associated with death in the univariate analysis were decreased frequency of dental visits; non‐use of dental floss; increased decayed, missing, and filled teeth index; presence of CP; and absence of CP treatment. Patients with CP had a higher risk of death from all causes compared with patients without CP in the univariate analysis for untreated patients (hazard ratio 2.65 [95% confidence interval 1.06 to 6.59]; P = 0.036) and to a lesser extent for treated patients (2.36 [1.01 to 5.59]; P = 0.047). These significant differences were not maintained after adjustments for confounders in the multivariate model.

Conclusions: These results suggest that poor oral health, including CP, is a common finding in patients undergoing HD. The results of this study call for intervention trials to test the hypothesis that treatment of CP improves survival in maintenance of patients undergoing HD.
Weight Status and Sexual Orientation: Differences by Age and Within Racial and Ethnic Subgroups
Authors: Deputy Nicholas P. , Boehmer Ulrike
Published: November 2013

Objectives. We determined differences in weight at age 18 years and at current age and weight change by sexual orientation within different racial/ethnic populations, stratifying by gender.

Methods. We used 2001–2007 data from the California Health Interview Survey, resulting in an unweighted sample of 120 274 individuals aged 18 to 74 years. Using regression models, we examined overweight status and change in weight by sexual orientation, stratifying by race/ethnicity and gender.

Results. Compared with heterosexual women of the same race/ethnicity, White and African American lesbians and bisexuals had increased likelihood of being overweight at age 18 years and maintaining overweight status during adulthood. Sexual minority status was unrelated to weight among Latinas and inconsistently linked to weight among Asian women compared with heterosexual women of the same race/ethnicity. Sexual minority status was protective against unhealthy weight among White, African American, Asian, and Latino men compared with heterosexual counterparts of the same race/ethnicity. This protective effect was seen after age 18 years except among African American bisexual men.

Conclusions. Our findings indicate a need for age- and culture-sensitive interventions that reduce weight or prevent weight gain in sexual minority women and men.
Associations Between Macrolevel Economic Factors and Weight Distributions in Low- and Middle-Income Countries: A Multilevel Analysis of 200 000 Adults in 40 Countries
Authors: Nandi Arijit , Sweet Elizabeth , Kawachi Ichiro , Heymann Jody , Galea Sandro
Published: November 2013

Objectives. We examined associations between macrolevel economic factors hypothesized to drive changes in distributions of weight and body mass index (BMI) in a representative sample of 200 796 men and women from 40 low- and middle-income countries.

Methods. We used meta-regressions to describe ecological associations between macrolevel factors and mean BMIs across countries. Multilevel regression was used to assess the relation between macrolevel economic characteristics and individual odds of underweight and overweight relative to normal weight.

Results. In multilevel analyses adjusting for individual-level characteristics, a 1–standard-deviation increase in trade liberalization was associated with 13% (95% confidence interval [CI] = 0.76, 0.99), 17% (95% CI = 0.71, 0.96), 13% (95% CI = 0.76, 1.00), and 14% (95% CI = 0.75, 0.99) lower odds of underweight relative to normal weight among rural men, rural women, urban men, and urban women, respectively. Economic development was consistently associated with higher odds of overweight relative to normal weight. Among rural men, a 1–standard-deviation increase in foreign direct investment was associated with 17% (95% CI = 1.02, 1.35) higher odds of overweight relative to normal weight.

Conclusions. Macrolevel economic factors may be implicated in global shifts in epidemiological patterns of weight.

Published: November 2013

Objectives. To investigate the association of indoor air pollution with the respiratory health of children, we evaluated the associations of children’s respiratory symptoms with asthma and recent home renovation.

Methods. We conducted a cross-sectional survey in a school recruitment sample of 31 049 children aged 2 to 14 years in 25 districts of 7 cities of northeast China in 2008–2009. The children’s parents completed standardized questionnaires characterizing the children’s histories of respiratory symptoms and illness, recent home renovation information, and other associated risk factors.

Results. The effects of home renovation in the past 2 years were significantly associated with cough, phlegm, current wheeze, doctor-diagnosed asthma, and current asthma. The associations we computed when combining the status of home renovation and family history of atopy were higher than were those predicted from the combination of the separate effects. However, the interactions between home renovation and family history of atopy on a multiplicative scale were not statistically significant (P > .05).

Conclusions. Home renovation is associated with increases in the prevalence of respiratory symptoms and asthma in children. The effects of different renovation materials on child respiratory health should be studied further.
Cigarettes Become a Dangerous Product: Tobacco in the Rearview Mirror, 1952–1965
Authors: Dorfman Lori , Cheyne Andrew , Gottlieb Mark A. , Mejia Pamela , Nixon Laura , Friedman Lissy C. , Daynard Richard A.
Published: November 2013

Tobacco control’s unparalleled success comes partly from advocates broadening the focus of responsibility beyond the smoker to include industry and government. To learn how this might apply to other issues, we examined how early tobacco control events were framed in news, legislative testimony, and internal tobacco industry documents. Early debate about tobacco is stunning for its absence of the personal responsibility rhetoric prominent today, focused instead on the health harms from cigarettes. The accountability of government, rather than the industry or individual smokers, is mentioned often; solutions focused not on whether government had a responsibility to act, but on how to act. Tobacco lessons can guide advocates fighting the food and beverage industry, but must be reinterpreted in current political contexts.
Design of Implementation Studies for Quality Improvement Programs: An Effectiveness–Cost-Effectiveness Framework
Authors: Cheung Ken , Duan Naihua
Published: November 2013

Translational research applies basic science discoveries in clinical and community settings. Implementation research is often limited by tremendous variability among settings; therefore, generalization of findings may be limited. Adoption of a novel procedure in a community practice is usually a local decision guided by setting-specific knowledge. The conventional statistical framework that aims to produce generalizable knowledge is inappropriate for local quality improvement investigations. We propose an analytic framework based on cost-effectiveness of the implementation study design, taking into account prior knowledge from local experts. When prior knowledge does not indicate a clear preference between the new and standard procedures, local investigation should guide the choice. The proposed approach requires substantially smaller sample sizes than the conventional approach. Sample size formulae and general guidance are provided.

Authors: Warner Kenneth E. , Sexton Donald W. , Gillespie Brenda W. , Levy David T. , Chaloupka Frank J.
Published: November 2013

Objectives. We assessed the impact of tobacco control on adult per capita cigarette consumption in the United States from 1964 to 2011.

Methods. We used logit regression to model the diffusion of smoking from 1900 to 2011. We also projected hypothetical cigarette consumption after 1963 in the absence of tobacco control. Model predictors included historical events such as wars, specific tobacco control interventions, and other influences.

Results. Per capita consumption increased rapidly through 1963, consistent with S-shaped (sigmoid) diffusion. The course reversed beginning in 1964, the year of publication of the first surgeon general’s report on smoking and health. Subsequent tobacco control policy interventions significantly reduced consumption. Had the tobacco control movement never occurred, per capita consumption would have been nearly 5 times higher than it actually was in 2011.

Conclusions. Tobacco control has been one of the most successful public health endeavors of the past half century. Still, the remaining burden of smoking in the United States augurs hundreds of thousands of deaths annually for decades to come. Reinvigorating the tobacco control movement will require novel interventions as well as stronger application of existing evidence-based policies.
Effect of Lactococcus lactis vs. Lactobacillus spp. bacteria on chicken body weight, mortality, feed conversion and carcass quality
Authors: Brzóska Franciszek , Śliwiński Bogdan , Stecka Krystyna
Published: November 2013

A total of 608 Ross 308 broiler chickens of both sexes were studied to determine the effect of Lactococcus lactis 847 bacteria compared to probiotic bacteria Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 on body weight, feed consumption and conversion, mortality, dressing percentage, postmortem carcass traits, composition of breast muscle tissue, and blood plasma traits. Feeding diets with bacteria to chickens did not increase body weight at 42 days of age or improve feed conversion compared to control chickens. It significantly reduced chicken mortality compared to the control group, from 3.3% to 1.4% (P<0.01). No significant differences were found in feed consumption and conversion. There were no significant differences in the weight of carcasses and their parts. Lactococcus lactis 847 and Lactobacillus plantarum 837 bacteria significantly increased dressing percentage (P<0.05). Lactococcus lactis 847 significantly increased liver weight (P<0.05). No significant differences were observed in carcass fatness, and in the dry matter, protein and fat content of breast muscles. Feeding diet with Lactobacillus plantarum 837 to chickens significantly decreased plasma triglyceride levels, and feeding diet with Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 significantly decreased the level of high-density cholesterol (P<0.05). In conclusion, Lactococcus lactis 847 bacteria in diet significantly reduce losses due to digestive disorders while having no effect on the quantity and proportion of saleable cuts in the carcass, the composition of breast muscles and basic blood parameters.

Authors: Bilik Krzysztof , Niwińska Barbara , Łopuszańska–Rusek Magdalena , Fijał Jerzy
Published: November 2013

An experiment was conducted to determine the degree to which feeding Polish Black-and-White Holstein-Friesian cows with total mixed rations (TMR) differing in the type of “energy” roughages (whole-crop maize silage, MS; winter barley silage, BS) and their proportion (70% or 50% in DM) relative to wilted meadow grass silage (GS) will affect the yield, chemical composition, fatty acid profile and technological suitability of milk, the quality traits and organoleptic score of some milk products (curd cheese, soft rennet cheese, creamery butter), and the fatty acid profile of butter fat. The study was carried out during the second trimester of lactation using 36 cows assigned to four analogous groups with 9 animals per group. It was found that replacing maize silage with barley silage in TMR diets had no significant effect on the yield, chemical composition, fatty acid content and technological suitability of milk, or on the content of major protein fractions and protein substances. Curd cheese and rennet cheese from the milk of cows fed diets with barley and wilted grass silages (groups BS/GS-I and BS/GS-II) and creamery butter from the milk of cows fed diets with a lower (50% DM) proportion of “energy” silages (MS/GS-II and BS/GS-II) were characterized by a higher (P≤0.01) content of solids and fat compared to analogous products from the milk of cows in the other groups (MS/GS-I and BS/GS-I). Butter from the milk of MS/GS-I and MS/GSII cows had a significantly higher content of PUFA (including C18:2 n-6, C18:3 n-6, C18:3 n-3 and CLA), and a lower content of SFA (from C-4 to C-16) compared to BS/GS-I and BS/GS-II cows. Regardless of the type of total mixed ration fed in the second trimester of lactation, the milk and milk products had desirable functional and technological properties.
The Centrality of Relationships for Pedagogy
Authors: Bishop Russell , Ladwig James , Berryman Mere
Published: November 2013

Te Kotahitanga is a research and professional development project that seeks to reduce educational disparities between indigenous Māori students and their non-Māori peers in New Zealand secondary schools. While evidence of the impact of the project on teachers’ practice and the associated gains made by Māori students has been published previously, in order for the work of Te Kotahitanga to contribute to the broader educational research community, its pedagogical premises require empirical verification. To do so, we must first establish the validity of the pedagogical data by addressing two questions: (a) To what degree can the data gathered in the collaborative processes of Te Kotahitanga be used as a measure of pedagogical quality? and (b) Do these data support the foundational hypothesis of the project, that “extended family” relationships, as understood by Māori people when using the Māori term, whanaungatanga, are a central necessary component of overall pedagogical quality? This article provides an account of the context of this work then presents an analysis directed to these questions in turn. First, our analysis of the observational data gathered during the Te Kotahitanga professional development process is presented, followed by the measures that were developed for each of the main dimensions of pedagogy addressed in this work. Second, using these measures we present our analysis of the inter-relation among these dimensions of pedagogy to test the Whanaungatanga pedagogical thesis.
Correcting for Test Score Measurement Error in ANCOVA Models for Estimating Treatment Effects
Authors: Lockwood J. R. , McCaffrey Daniel F.
Published: November 2013

A common strategy for estimating treatment effects in observational studies using individual student-level data is analysis of covariance (ANCOVA) or hierarchical variants of it, in which outcomes (often standardized test scores) are regressed on pretreatment test scores, other student characteristics, and treatment group indicators. Measurement error in the prior test scores, which typically is both large and heteroscedastic, is regularly overlooked in empirical analyses and may erode the ability of regression models to adjust for student factors and may result in biased treatment effect estimates. We develop extensions of method-of-moments, Simulation-Extrapolation, and latent regression approaches to correcting for measurement error using the conditional standard errors of measure of test scores, and demonstrate their effectiveness relative to simpler alternatives using both simulation and a case study of teacher value-added effect estimation using longitudinal data from a large suburban school district.

Published: November 2013

The experiment was conducted during the period from January to December, 2008 at the Laboratory of Biotechnology, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh. A two step procedure was followed for direct plant regeneration of potato. Murashige and Skoog (MS) basal medium supplemented with 0.5 mg l-1 IBA and 30 g sugar was used for in vitro potato plants development via nodal cuttings. Leaves and internodes of in vitro grown potato variety Asterix was cultured in instant MS basal medium supplemented with 0.01 mg l-1 IAA, 0.20 mg l-1 GA3, 44.0 g l-1 CaCl2, 20 g sucrose. Eight different concentrations of Zeatin riboside (ZR) viz., 0, 0.1, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 mg l-1 along with above supplements (step II) were tested for in vitro direct regeneration of potato. MS medium supplemented with 4-5 mg l-1 of ZR performed better in respect of shoot induction from internodal explants. All the internodes produced shoots directly from the basal and apex region within 18-21 days and from the leaves within 21-28 days in 2 - 5 mg l-1 ZR. Maximum 43.20 and 7.25 shoots were recorded from each internode and leaf explant, respectively. In vitro shoots treated with 0.5 mg l-1 of IBA produced roots profusely within 21 days.DOI: http://dx.doi.org/10.3329/bjpbg.v24i1.16307

Published: November 2013

The experiment was carried out in Randomized Completely Block Design (RCBD) during the Boro season 2006-2007 (Mid October to mid May) at Bangabandhu Sheikh Mujibur Rahaman Agricultural University-Gazipur. Alok showed significant bi but its deviation from regression (S2di) invalided its linear prediction. Among the three CMS lines CMS-2 was stable for % OCR due to considerable mean, phenotypic index, regression coefficient near unity (bi ? 1) as well as insignificant deviation from regression (S2di ? 0)  and CMS-1 was highly responsive to seedling ages due to  significant bi and insignificant S2di. Although, Alok showed significant bi but its deviation from regression (S2di) invalided its linear prediction. Maximum out crossing rate was obtained from CMS-2 irrespective of seedling ages. On the other hand 43 days old seedling of CMS-1 gave the maximum out crossing rate. CMS-2 was highly responsive to yield over seedling ages. CMS-1 showed insignificant regression coefficient (bi) indicating stability over seedling ages but deviation from regression (S2di) was significant which invalided its linear prediction. Alok showed lower mean, significant regression coefficient (bi) and insignificant deviation from regression (S2di) indicating responsitive to favourable seedling ages with comparatively lower yield. 43 days old seedlings of CMS-2 gave the maximum hybrid seed production rate.DOI: http://dx.doi.org/10.3329/bjpbg.v24i1.16995

Inheritance of fertility restoration was studied in crosses involving ten elite restorer lines of rice viz. BR6839-41-5-1R, BR7013-62-1-1R, BR7011-37-1-2R, BR10R, BR11R, BR12R, BR13R, BR14R, BR15R and BR16R and one male sterile line Jin23A with WA sources of cytoplasmic male sterility. The segregation pattern for pollen fertility of F2 and BC1 populations of crosses involving Jin23A indicated the presence of two independent dominant fertility restoring genes. The mode of action of the two genes varied in different crosses revealing three types of interaction, i.e. epistasis with dominant gene action, epistasis with recessive gene action, and epistasis with incomplete dominance.DOI: http://dx.doi.org/10.3329/bjpbg.v24i1.16997

Twenty four hybrid rice varieties of diverse origin were studied for genetic variability, correlation and path analysis under medium high land of Gazipur. The PCV values were greater than GCV, revealing little influence of environment in character expression. High values of heritability along with moderate genetic advance were observed for panicle/m2, days to 50% flowering and plant height. Grain yield showed positive significant association with number of effective tillers/hill, panicle/m2, spikelet fertility and thousand grain weight at both genotypic and phenotypic levels. Same traits had highest significant positive effect on yield.DOI: http://dx.doi.org/10.3329/bjpbg.v24i1.16999

Published: November 2013

Phenotypic stability of 12 rice genotypes for plant height, days to maturity and yield were assessed at five different locations through regression and deviation from regression using Additive Main Effect and Multiplicative Interaction (AMMI) model. The result showed highly significant genotypic and G x E interaction. The G x E interaction influenced the relative ranking of the genotypes tested, BR1A/BR827R, Teea, BRRI dhan33 and Mayna showed low interaction effect with score nearest to zero with above average yield. While two genotypes BRRI hybrid dhan4 and Heera995 exhibited high positive interaction effect, gave mean grain yield around 5 ton/ha and was better suited to favorable environments. Similarly AMMI characterized the environments and identified Satkhira as a favorable environment for the better expression of the trait studied.DOI: http://dx.doi.org/10.3329/bjpbg.v24i2.17001
EXPRESSION PATTERNS OF AN ABIOTIC STRESS-INDUCIBLE DEHYDRATION RESPONSIVE ELEMENT BINDING PROTEIN-2 (DREB2) GENE IN TOMATO
Authors: Islam M. S. , Wang M. H.
Published: November 2013

A novel DREB (dehydration-responsive element binding) gene, designated as LeDREB2, was isolated from tomato. Based on multiple sequence alignment and phylogenetic characterization, LeDREB2 gene was classified into an A-2 group member of the DREBs family. We examined the expression pattern of LeDREB2 gene in tomato under different abiotic stresses. Southern blot analysis showed that LeDREB2 is a single copy gene in tomato genome. The organ specific expression profiling indicated that LeDREB2 gene was strongly expressed in young leaves and roots but weak expression in mature leaves and shoots. Northern blot analysis revealed that various kinds of environmental stress such as salt, drought and cold were significantly induced by LeDREB2 gene after application of time courses treatments except little increase in ABA. Our findings showed that the expression of LeDREB2 gene was induced by high salinity, drought and cold but not by the abscisic acid (ABA) treatment. These results indicated that the LeDREB2 gene is a member of the DREB transcription factors, which may play a role in both abiotic and oxidative stress responses.DOI: http://dx.doi.org/10.3329/bjpbg.v25i1.17006

Published: November 2013

Genetic divergence among fifty exotic rice genotypes along with two check varieties were estimated using D2 and principal component analysis. The study was undertaken to select suitable donor parents for use in improved breeding program of Bangabandhu Sheikh Mujibur Rahman Agricultural University in 2009. Principal component analysis (PCA) revealed that the first five axes accounted for 58.10% of the total variation. As per cluster analysis, the genotypes were grouped into seven clusters consisting 11, 16, 7, 11, 1, 2 and 4 genotypes which revealed that there exist considerable diversity among the genotypes. Considering the magnitude of genetic distance, contribution of different characters towards the total divergence and magnitude of cluster means for different characters, the genotypes RG-BU-08-057, 61, 65, 67, 69, 71, 85, 86, 88, 94, 96, 98 and 99 might be selected as a suitable parent for future hybridization program.DOI: http://dx.doi.org/10.3329/bjpbg.v25i1.17007

High genotypic co-efficient of variation (GCV) was observed for days to 50% flowering, days to first flowering and spikelet sterility whereas low genotypic co-efficient of variation (GCV) was observed for grain length and filled grains per panicle. High heritability with high genetic advance in percent of mean was observed for days to 50% flowering and pollen sterility indicated that this trait was under additive gene control and selection for genetic improvement for this trait would be effective. On the other hand, high heritability with low genetic advance in percent of mean was observed in days to harvesting and grain length which indicated that non-additive gene effects were involved for the expression of this character and selection for such trait might not be rewarding. Correlation studies revealed that highest significant positive association of grain yield was with days to first flowering, days to harvesting, filled grains per panicle followed by grain length at genotypic and phenotypic level. Path co-efficient analysis revealed that maximum direct contribution towards grain yield with days to harvesting followed by filled grains per panicle.DOI: http://dx.doi.org/10.3329/bjpbg.v25i1.17009

Published: November 2013

The present study was undertaken for callus induction and subsequent plantlet regeneration in blackgram. The study comprised of experiments for callus initiation, shoot regeneration and plantlet formation from cotyledon, hypocotyl, root tip and shoot tip explants. The effects of explants and different concentrations and combinations of BAP (0.0, 1.0, 2.5, 5.0 and 10 mg L-1) and NAA (0.0, 0.5, 1.0, 1.5 and 2.0 mg L-1)) on callus induction were investigated first. Among the explants, hypocotyls showed the best performance in callus formation (92.33%) when cultured on MS medium supplemented with 2.5 mg L-1) BAP and 1.5 mg L-1) NAA followed by cotyledon, shoot tip and root tip explants, respectively. The height percentage of shoot regeneration from the calli derived from hypocotyls (56.33%) was achieved in MS medium supplemented with 3.0 mg L-1) BAP and 0.3 mg L-1) NAA and 0.5 mg L-1) GA3. Calli from other explants had no shoot regeneration. The regenerated shoots were transferred to rooting medium supplemented with different concentrations of IBA and NAA. The high frequency (100 %) of rooting was observed with MS medium supplemented with 0.5 mg L-1) IBA. The rooted plants were transferred to pots for hardening.DOI: http://dx.doi.org/10.3329/pa.v19i2.16917 Progress. Agric. 19(2): 27 - 35, 2008

Published: November 2013

To investigate the effects of arbuscular mycorrhiza (AM) and phosphorus (P) rates on the uptake of primary and secondary nutrients by tomato (Lycopersicon esculentum Milli) cv. BARI Tomato-2 seedlings, under P levels ranging from low to excessive, plants were grown in five levels of P (0, 7.5, 15.0, 22.5 and 30.0 mg P kg-1 soil) as TSP, either inoculated with AM or without AM. The total dry matter yield and uptake of N, P, K, S, Ca and Mg nutrients was significantly influenced by AM inoculation. Nutrient use efficiency in the AM-inoculated seedlings was also significantly higher than that in uninoculated seedlings. The application of different levels of P lonely increased different nutrients and its uptake positively up to certain level, but at higher level influenced negatively. The N, P, K, S, Ca and Mg content and uptake all were the highest when P applied @ 30 kg ha-1 and the lowest @ 0 kg P ha-1 but uptake found the lowest @ 60 kg P ha-1. There was a significant interaction effect of AM and P levels on nutrients content and their uptakes positively up to certain level, but at higher level of P combination influenced negatively. Among the treatment combinations, P30 x I showed the highest nutrient contents under study and their uptakes but dry matter yield gave the highest value when AM was applied with P @ 15 kg ha-1.DOI: http://dx.doi.org/10.3329/pa.v19i2.16932 Progress.

Published: November 2013

The merit of Red Chittagong cows-a promising indigenous cattle genetic resource of Bangladesh was evaluated by using test day milk yield records of total 41 individuals. The data were collected from the Nucleus Herd of Red Chittagong (RC) cattle maintained at Bangladesh Agricultural University, Mymensingh from June, 2007 to October, 2008 under supervised animal recording system along with the previously recorded data from 2005 was also taken into consideration. Data were then analyzed for evaluating the cows based on lactation yield and average daily milk yield. Average lactation yield and daily milk yield were 453.86 ± 59.61 and 1.99 ± 0.14 kg, respectively. The highest lactation yield (538.04 kg) and daily milk yield (2.3 kg) was found in 4th and 5th lactation, respectively. The most probable producing ability (MPPA) of RC cows was calculated by using the test day records and then the animals were ranked on the basis of their MPPA value. For MPPA calculation two methods were followed; cows repeated lactation performance (MPPA1) and within lactation repeated test day records and averaged (MPPA2). The highest MPPA for lactation yield was shown by the cow no. 36 (645.61 kg) and the highest MPPA1 and MPPA2 for daily milk yield were 2.83 and 3.46 kg, respectively for cow no. 03. The result of this study suggests that test-day yields may well be used for genetic evaluation of cows to make recurrent selection decision in cattle breeding programs.DOI: http://dx.doi.org/10.3329/pa.v19i2.16950 Progress.

Published: November 2013

Five hormone doses viz., 40, 60, 70, 85 and 90 mg of Pituitary gland (PG)/kg body endangered Tarabaim (Macrognathus aculeatus) were tested and they were designated as Treatments T1, T2, T3, T4 and T5, respectively. Significantly (p<0.05) higher fertilization (86%) and hatching rates (50%) were obtained from T5 (90 mg of PG extract/kg body weight) than those of other treatments. However, T4 (85 mg of PG extract/kg, body weight) and T3 (70 mg of PG extract/kg body weight) gave the highest (90%) ovulation rate. In May and June, the highest fertilization rate of 82% and 86% respectively and hatching rate 45% and 75%, respectively were obtained at the temperature ranged from 27.0 to 33.0ºC. In conclusion, PG extract at a dose of 90 mg/kg body weight appeared to be the suitable dose for artificial propagation of M. aculeatus, May and June are the suitable months for its artificial propagation.DOI: http://dx.doi.org/10.3329/pa.v19i2.16951 Progress.

Authors: Hasan M , Khan MMR , Sumida M
Published: November 2013

In order to investigate the morphological and genetic variation of Indian bullfrog Hoplobatrachus tigerinus, live samples were collected from three populations located in Khulna (southern part), Char Nilokhia and Netrokona (central part) in Bangladesh. The proportions of head length and head width (HL : HW), eye length and tympanum diameter (EL:TD), head length and snout length (HL : SL), internarial space and interorbital distance (IN:IOD) and internarial space and distance from nostril to tip of snout (IN:NS) of the Khulna population were significantly higher (p<0.05) than those of the other two populations. For allozyme study, 4 enzymes were screened, where 5 presumptive scorable loci were identified. The highest values of mean proportion of polymorphic loci (<0.95), mean number of alleles per locus and mean number of heterozygous loci per individual were observed in the Khulna population (60%, 1.60 and 14.0% respectively). The pairwise genetic differentiation (FST and Neis D) was the highest (0.279 and 0.157, respectively) between the Khulna and Netrokona populations. The UPGMA dendrogram showed two clusters i.e. the Char Nilokhia and Netrokona populations formed one cluster, whereas the Khulna population alone made another cluster. These results suggested that the Khulna population diverged morphologically and genetically from the other two populations probably due to its geographical distance. Further extensive study will be necessary for elucidating the whole aspects of differentiation in H. tigerinus from Bangladesh.DOI: http://dx.doi.org/10.3329/pa.v19i2.16954 Progress.

The study was conducted for a period of twelve months from January to December 2006 to determine the gonadosomatic index (GSI) and fecundity of Mystus gulio. Total 370 of Mystus gulio were examined during the study period. The sex ratio (male:female) of the investigated fish was 1:1.22 and generally female was larger than male. The fish was found to have a wide spawning season (March to November) with a single spawning peak in July as indicated by the gonadosomatic index and ova diameter. Fecundity of the fish was ranged from 3,891 to 1,68,358 with an average of 32,909.49 during the period of study and was found to increase with the increase of body length and weight. The relationships between fecundity and total-length, body-weight, gonad-length and gonad-weight were found linear and statistically highly significant (p<0.05).DOI: http://dx.doi.org/10.3329/pa.v19i2.16957 Progress.

Post harvest qualitative and quantitative changes have been studied in an important crustacean species prawn, Golda (Macrobrachium rosenbergii) of Bangladesh at various stages of handling Golda have been studied. Detailed information on post-harvest handling, storage, transportation, and distribution of prawn using pre-tested questionnaires was collected from some selected farms and depots of four Golda producing districts viz. Khulna, Bagerhat, Jessore and Norail area. The information on various aspects was collected through interview with cross section of people engaged in farms and depots. The aspects of information collected on Golda farms were: farm conditions, infrastructure, harvesting, farm production, post-harvest care, transportation and quality measures. Information collected on various aspects of depots was: infrastructure facilities, condition of shrimp during receiving, handling, transportation, washing and owners opinion about the quality of prawn from previous year experiences. The post-harvest losses of Golda is due to soft shell, improper washing or washing with unclean water, longer duration of harvesting, exposure of shrimp at high ambient temperature for a long time (delayed icing), contamination, piled up on a dirty floor, general lack of hygiene and dipping in water to weight gain was about 1-4% of the total harvested quantity.DOI: http://dx.doi.org/10.3329/pa.v19i2.16959 Progress.

Published: November 2013

The cave of Isturitz is one of the most important archaeological sites of the prehistory of Western Europe. Human occupations followed each other in the cavity from at least the Middle Paleolithic to the Roman age. In 1913, Passermard started archaeological excavations there, and a calcite pillar was discovered next to the original entrance that was sculpted with a dozen of animal representations. In this excavation, the Magdalenian levels yielded a considerable quantity of portable art objects. In the last few years, several workers have resumed the study of those pieces. Since 2011, we have created a research team for the study of the parietal figures of the cave, as well as other elements, for example the objects embedded in the walls. We present here our first results, which improve in the understanding of the artistic activities of Upper Palaeolithic peoples by shedding light at the art analyzed in Isturitz.
Interplay of Stem Cell Characteristics, EMT, and Microtentacles in Circulating Breast Tumor Cells
Authors: Charpentier Monica , Martin Stuart
Published: November 2013

Metastasis, not the primary tumor, is responsible for the majority of breast cancer-related deaths. Emerging evidence indicates that breast cancer stem cells (CSCs) and the epithelial-to-mesenchymal transition (EMT) cooperate to produce circulating tumor cells (CTCs) that are highly competent for metastasis. CTCs with both CSC and EMT characteristics have recently been identified in the bloodstream of patients with metastatic disease. Breast CSCs have elevated tumorigenicity required for metastatic outgrowth, while EMT may promote CSC character and endows breast cancer cells with enhanced invasive and migratory potential. Both CSCs and EMT are associated with a more flexible cytoskeleton and with anoikis-resistance, which help breast carcinoma cells survive in circulation. Suspended breast carcinoma cells produce tubulin-based extensions of the plasma membrane, termed microtentacles (McTNs), which aid in reattachment. CSC and EMT-associated upregulation of intermediate filament vimentin and increased detyrosination of α-tubulin promote the formation of McTNs. The combined advantages of CSCs and EMT and their associated cytoskeletal alterations increase metastatic efficiency, but understanding the biology of these CTCs also presents new therapeutic targets to reduce metastasis.
