Cadmium availability and uptake by rice from lime, cow-dung and poultry manure amended Ca-contaminated paddy soil

Industrial wastes and effluents are being discharged directly to soils, canals and rivers, which may contain a lot of toxic heavy metals like cadmium (Cd). Thus, the polluted soils need to be amended for crop production. With this idea in mind,pot experiments were conducted at Bangladesh Agricultural University to examine the effect of organic and inorganic amendments on growth, yield and Cd concentrations in rice grown in polluted soils. The addition of cow-dung (CD), poultry manure(PM) and lime significantly increased the grain and straw yields of rice, reduced Cd concentration and uptake of Cd in grain and straw compared with control. However, the addition of PM increased more rice yields, reduced more Cd concentration and uptake and decrease the heavy metal phytoavailability

Trends and clinico-epidemiological features of human rabies cases in Bangladesh 2006–2018

Vaccinating dogs against rabies is an effective means of reducing human rabies. We subjected 1327 clinically diagnosed human rabies death and mass dog vaccination (MDV) data during 2006–2018 to quantify the impacts of MDV on human rabies incidence in Bangladesh and a subset of rabies death data (422) for clinico-epidemiological analysis. A positive and increasing trend of MDV (p = 0.01 and tau = 0.71) and a negative and declining trend (p < 0.001 and tau = −0.88) of human rabies cases (Correlation coefficient: −0.82) have been observed. Among 422 deaths, the majority (78%) of the victims sought treatment from traditional healers, and 12% received post-exposure prophylaxis (PEP). The mean incubation period of rabies in cases with exposure sites on the head & neck (35 days) was shorter than the upper limb (mean = 64 days, p = 0.02) and lower limb (mean = 89 days, p < 0.01). MDV has been found to be effective for reducing human rabies cases in Bangladesh. Creating awareness among the animal bite victims to stop reliance on traditional healers rather seeking PEP, addressing the role of traditional healers through awareness education programme with respect to the treatment of dog bites, ensuring availability of PEP, and continuing to scale up MDV may help to prevent human rabies deaths

Risk of Nosocomial Transmission of Nipah Virus in a Bangladesh Hospital

We conducted a seroprevalence study and exposure survey of healthcare workers to assess the risk of nosocomial transmission of Nipah virus during an outbreak in Bangladesh in 2004. No evidence of recent Nipah virus infection was detected despite substantial exposures and minimal use of personal protective equipmen

Assessment of genetic diversity of brinjal (Solanum melongena L.) germplasm by RAPD markers

Assessment of genetic diversity in a crop species is prerequisite to its improvement. The use of germplasm with distinct DNA profiles helps to generate genetically diversified breeding populations. The present study was carried out to investigate the genetic diversity in brinjal or eggplant (Solanum melongena L.) using random amplified polymorphic DNA (RAPD). Fifteen brinjal germplasm and three decamer primers were used for random polymorphic DNA assay. A total of 17 fragments were obtained, out of which 12 (70.59%) were polymorphic. Each primer generated 4 to 8 amplified fragments with an average of 5.67 fragments per primer. The highest genetic distance (0.8873) and the lowest genetic identity (0.4118) were observed in Laffa (Elongated) versus Jessore L and Dharola combinations. The lowest genetic distance (0.1525) was observed in several cultivars. The unweighted pair-group method of arithmetic means (UPGMA) dendrogram was constructed from genetic distance and all brinjal cultivars were grouped into five clusters. The genetic diversity of brinjal cultivars reported in this study will be useful when planning future crosses amongst these cultivars

Response of potato to ash as an alternative source of potassic fertilizer

An experiment was carried out during rabi season of 2011-2012 in the experimental field of Soil Science, Bangladesh Agricultural University (BAU), Mymensingh. The objectives of present research work was to evaluate ash as an alternative source of potassic fertilizer for potato cultivation. The treatment combinations were i) Control (No K), ii) 100% K of recommended dose from muriate of potash (MoP), iii) 75% K from MoP+ 25% K from ash, iv) 50% K from MoP + 50% K from ash, v) 25% K from MoP + 75% K from ash, and vi) 100% K from ash. The result of the experiment indicated that various combinations of ash and MoP influenced the yield, yield contributing characters (length of the tubers, breadth of the tubers, number of tubers per hill, weight of tubers per hill, weight of ten tubers and gross yield of tubers per plot), K content of potato as well as weed infestation. Among the treatments the highest yield was obtained from 50% K from MoP + 50% from ash (T3) treated plot. The K content in the potato tuber and weed infestation was also highest for that plot. Considering the yield contributing parameters, yield and number of weeds the T3 (50% K from MoP + 50% K from ash) treatment was found more suitable than others

Response of yield, nitrogen use efficiency and grain protein content of wheat (Triticum aestivum L.) varieties to different nitrogen levels

A field experiment was carried out in order to investigate the response of nitrogen use efficiency and yield of two wheat varieties to different nitrogen levels. The wheat varieties, viz. Bijoy (V1) and Prodip (V2) were tested under 4 levels of nitrogen (N0 = 0 kg N/ha, N1 = 60 kg N/ha, N2 = 120 kg N/ha and N3 = 180 kg N/ha) where wheat varieties assigned in main plot and nitrogen treatments in subplot. Grain yield was increased with increasing rates of nitrogen. Maximum grain yield (3.85 kg/ha) produced by the variety Prodip when N applied @ 180 kg/ha and minimum (1.15 kg/ha) by the variety Bijoy under control treatments. Interactions of two variety and nitrogen levels; N uptake by grain and straw increased with increasing nitrogen levels. Highest N uptake by grain (90.60 kg/ha) and straw (25.53 kg/ha) were observed from the variety Prodip with 180 kg N/ha. Highest (38.66) N use efficiency (NUE) was noticed in Prodip when received 60 kg N/ha. Grain protein (%) also showed maximum value (14.29) when Prodip fertilized with 180 kg N/ha. Between two varieties, Prodip was the best performer with 180 kg N/ha due to maximum nitrogen content and upake in grain and straw, maximum N use efficiency fertilizer recovery percentage and grain protein

Impact of obstructive sleep apnea on the occurrence of restenosis after elective percutaneous coronary intervention in ischemic heart disease

<p>Abstract</p> <p>Rationale</p> <p>There is growing evidence that obstructive sleep apnea is associated with coronary artery disease. However, there are no data on the course of coronary stenosis after percutaneous coronary intervention in patients with obstructive sleep apnea.</p> <p>Objectives</p> <p>To determine whether sleep apnea is associated with increased late lumen loss and restenosis after percutaneous coronary intervention.</p> <p>Methods</p> <p>78 patients with coronary artery disease who underwent elective percutaneous coronary intervention were divided in 2 groups: 43 patients with an apnea hypopnea – Index < 10/h (group I) and 35 pt. with obstructive sleep apnea and an AHI > 10/h (group II). Late lumen loss, a marker of restenosis, was determined using quantitative coronary angiography after 6.9 ± 3.1 months.</p> <p>Main results</p> <p>Angiographic restenosis (>50% luminal diameter), was present in 6 (14%) of group I and in 9 (25%) of group II (p = 0.11). Late lumen loss was significant higher in pt. with an AHI > 10/h (0.7 ± 0.69 mm vs. 0.38 ± 0.37 mm, p = 0.01). Among these 35 patients, 21(60%) used their CPAP devices regularly. There was a marginally lower late lumen loss in treated patients, nevertheless, this difference did not reach statistical significance (0.57 ± 0.47 mm vs. 0.99 ± 0.86 mm, p = 0.08). There was no difference in late lumen loss between treated patients and the group I (p = 0.206).</p> <p>Conclusion</p> <p>In summary, patients with OSA and coronary artery disease have a higher degree of late lumen loss, which is a marker of restenosis and vessel remodeling after elective percutaneous intervention.</p

Pressure study of the noncentrosymmetric 5d-electron superconductors CaMSi3 (M= Ir, Pt)

We report hydrostatic pressure study on the Rashba-type noncentrosymmetric superconduc- tors CaMSi3 (M= Ir, Pt). The temperature dependence of the resistivity for both compounds is well described by the conventional Bloch-Gr\"uneisen formalism at each pressure. This fact suggests that electron-phonon scattering is dominant in these compounds. The superconducting critical temperature Tc decreases by pressure as \sim 0.2 K/GPa above 0.41 GPa to 2 GPa for both compounds. This behavior of Tc can be explained with a modest decrease of the density of states based on the conventional BCS theory.Comment: 4 pages, 4 figure
