Bisphenol-A (BPA) is an endocrine disruptor that is widely used in the manufacture of polycarbonate plastics, epoxy resins and dental sealants. It has adverse effects on reproduction. Black seed oil is frequently used as folk medicine for the promotion of good health and treatment of many ailments. The study was carried out to investigate the effect of Bisphenol-A (BPA) and black seed oil (BSO) on hematological parameters, hormone, sperm parameters and patho-physiological changes of testis in mice. A total of 15 male Swiss Albino mice (Mus musculus), of 25-28 days were used and randomly divided into 3 groups consisting 5 mice in each group. Group A served as vehicle control whereas group B and group C were as BPA and BPA plus BSO group respectively. Both BPA @ 50 mg/kg/day and BSO @ 1ml/kg/day were administered orally. Results revealed that BPA caused reduced hematological parameters (Hb, TEC, and PCV) in mice. Inclusion of BSO in BPA treated mice prevented the alterations of those values. Serum T4 and testosterone concentration were significantly (p [J Bangladesh Agril Univ 2021; 19(2.000): 223-229]

Background Cervical cancer is a gynecologic cancer type that develops in the cervix, accounting for 8% mortality of all female cancer patients. Infection with specific human papillomavirus (HPV) types is considered the most severe risk factor for cervical cancer. In the context of our socioeconomic conditions, an increasing burden of this disease and high mortality rate prevail in Bangladesh. Although several researches related to the epidemiology, HPV vaccination, and treatment modalities were conducted, researches on the mutation profiles of marker genes in cervical cancer in Bangladesh remain unexplored. Methods In this study, five different genomic regions within the top three most frequently mutated genes (EGFR, KRAS and PIK3CA) in COSMIC database with a key role in the development of cervical cancers were selected to study the mutation frequency in Bangladeshi patients. In silico analysis was done in two steps: nucleotide sequence analysis and its corresponding amino acid analysis. Results DNA from 46 cervical cancer tissue samples were extracted and amplified by PCR, using 1 set of primers designed for EGFR and 2 sets of primers designed for two different regions of both PIK3CA and KRAS gene. In total, 39 mutations were found in 26 patient samples. Eleven different mutations (23.91%), twenty-four different mutations (52.17%) and four mutations (8.7%) were found in amplified EGFR, PIK3CA and KRAS gene fragments, respectively; among which 1 (EGFR) was common in seven patient samples and 2 (PIKCA) were found in more than 1 patient. Our study shows that except for KRAS, the frequency of observed mutations in our patients is higher than those reported earlier in other parts of the world. Most of the exonic mutations were found only in the PIK3CA and EGFR genes. Conclusions The study can be used as a basis to build a mutation database for cervical cancer in Bangladesh with the possibility of targetable oncogenic mutations. Further explorations are needed to establish future diagnostics, personalized medicine decisions, and other pharmaceutical applications for specific cancer subtypes.

An incomplete understanding of the molecular mechanisms behind impairment of lung pathobiology by COVID-19 complicates its clinical management. In this study, we analyzed the gene expression pattern of cells obtained from biopsies of COVID-19-affected patient and compared to the effects observed in typical SARS-CoV-2 and SARS-CoV-infected cell-lines. We then compared gene expression patterns of COVID-19-affected lung tissues and SARS-CoV-2-infected cell-lines and mapped those to known lung-related molecular networks, including hypoxia induced responses, lung development, respiratory processes, cholesterol biosynthesis and surfactant metabolism; all of which are suspected to be downregulated following SARS-CoV-2 infection based on the observed symptomatic impairments. Network analyses suggest that SARS-CoV-2 infection might lead to acute lung injury in COVID-19 by affecting surfactant proteins and their regulators SPD, SPC, and TTF1 through NSP5 and NSP12; thrombosis regulators PLAT, and EGR1 by ORF8 and NSP12; and mitochondrial NDUFA10, NDUFAF5, and SAMM50 through NSP12. Furthermore, hypoxia response through HIF-1 signaling might also be targeted by SARS-CoV-2 proteins. Drug enrichment analysis of dysregulated genes has allowed us to propose novel therapies, including lung surfactants, respiratory stimulants, sargramostim, and oseltamivir. Our study presents a distinct mechanism of probable virus induced lung damage apart from cytokine storm.

The field experiment was conducted at MLT site Pirganj, Rangpur and Hatibandha’ Lalmonirhat for two consecutive years 2015-16 and 2016-17 to introduce T. Aus in the fallow period and to study the comparative agronomic performance and economic return of two cropping sequences (viz. improved cropping pattern; Maize -T. Aus - T. Aman rice and existing cropping pattern; Maize-Fallow-T. Aman rice) for increasing cropping intensity, productivity and land use efficiency. The experiment was laid out in randomized complete block design with six dispersed replications. Two years mean data showed that the improved management practices for the pattern provided significantly higher yield in improved pattern. Higher rice equivalent yield (REY) of cropping system (mean value 17.34 t ha -1 ) was recorded with the improved pattern over existing pattern at MLT site Pirganj. REY increased 4.60 t ha -1 by inclusion of T. Aus with improved production technologies for the component crops. Similar results were also found in Hatibandha. The gross return of the improved pattern was BDT 346764 ha -1 which was more than 33.56% higher than farmers’ pattern of BDT 259640 ha -1 at MLT site Pirganj and in Hatibandha gross return of the improved pattern was BDT 342800 ha -1 which was more than 27.77% higher than farmers’ pattern of BDT 268300 ha -1 . The gross margin was higher in improved cropping pattern in both locations than existing pattern due to addition of T. Aus. Progressive Agriculture 29 (2): 107-116, 2018

Productivity of the cropping system is critical to the food security of Bangladesh. However, many concerns about the sustainability of cropping system exist because of lack of advance knowledge of farming. In this context, a study was performed in the agro-ecological zone of the Tista Mendar Floodplain agro ecological zone (AEZ-3) at Jaldhaka subdistrict under Nilphamary district of Bangladesh. By reorganization of existing cropping patterns (using Linear Programming Model) gross output (7% to 21%), gross margin (12% to 20%) and labour employment (6% to 20%)have been increased from plan1(existing plan) to plan2 (by reorganization of existing lands). The cause of increase gross output, gross margin andlabour employment was some cultivated land from less efficient cropping patterns has been transferred to more efficient cropping patterns. Again, by reorganization of existing and improved cropping patterns, some lands of existing patterns have been shifted to improved cropping pattern. As a result, gross out (17% to 31%), gross margin (27% to 32%) and labour employment (13% to 26%) have been raised from plan1 to plan 3 (by combination of improved technologies with existing technologies). The result of on farm demonstration showed gross output, gross margin and labour employment have been increased 24% to 53%, 32% to 51% and 12% to 47% from plan1 to plan 3, respectively. So, this study suggest, optimum farm plan with the combination of existing and improved cropping pattern will increase farm output and generate additional employment and improved food security.Progressive Agriculture 28 (3): 204-215, 2017

Liquid Chromatography tandem mass spectrometry (LC-MS/MS) is used for the diagnosis of more than 30 inborn errors of metabolisms (IEMs). Accurate and reliable diagnosis of IEMs by quantifying amino acids (AAs) and acylcarnitines (ACs) using LC-MS/MS systems depend on the establishment of age-specific cut-offs of the analytes. This study aimed to (1) determine the age-specific cut-off values of AAs and ACs in Bangladesh and (2) validate the LC-MS/MS method for diagnosis of the patients with IEMs. A total of 570 enrolled healthy participants were divided into 3 age groups, namely, (1) newborns (1-7 days), (2) 8 days–7 years, and (3) 8–17 years, to establish the age-specific cut-offs for AAs and ACs. Also, 273 suspected patients with IEMs were enrolled to evaluate the reliability of the established cut-off values. Quantitation of AAs and ACs was performed on an automated LC-MS/MS system using dried blood spot (DBS) cards. Then the specimens of the enrolled clinically suspected patients were analyzed by the established method. Nine patients came out as screening positive for different IEMs, including two borderline positive cases of medium-chain acyl-CoA dehydrogenase deficiency (MCAD). A second-tier test for confirmation of the screening positive cases was conducted by urinary metabolic profiling using gas chromatography- mass spectrometry (GC-MS). Out of 9 cases that came out as screening positive by LC-MS/MS, seven cases were confirmed by urinary GC-MS analysis including 3 cases with phenylketonuria, 1 with citrullinemia type II, 1 with methylmalonic acidemia, 1 with isovaleric acidemia and 1 with carnitine uptake defect. Two borderline positive cases with MCAD were found negative by urinary GC-MS analysis. In conclusion, along with establishment of a validated LC-MS/MS method for quantitation of AAs and ACs from the DBS cards, the study also demonstrates the presence of predominantly available IEMs in Bangladesh.

Obesity is a pandemic which adds greatly to health care costs through its association with type 2 diabetes, metabolic syndrome, cardiovascular disease, and cancers. The aim of this research is to investigate the effects of different concentrations of butyric acid on changes of body weight, blood biochemical parameters, and liver histo-texture in mice. Total twenty Swiss albino mice were divided into 4 groups viz Group A, B, C and D. Group A act as control while Group B, Group C and Group D were received 3 mM, 5 mM, and 7 mM/kg b.wt butyric acid respectively, throughout the experimental period. On the 60th day, blood and liver samples were collected for biochemical analysis and histopathology respectively. Results showed that body weight increased significantly (p [ J Adv Biotechnol Exp Ther 2021; 4(3.000): 415-423]

Treatment for acute myeloid leukemia (AML) remains suboptimal and many patients remain refractory or relapse upon standard chemotherapy based on nucleoside analogs plus anthracyclines. The crosstalk between AML cells and the BM stroma is a major mechanism underlying therapy resistance in AML. Lenalidomide and pomalidomide, a new generation immunomodulatory drugs (IMiDs), possess pleiotropic anti-leukemic properties including potent immune-modulating effects and are commonly used in hematological malignances associated with intrinsic dysfunctional BM such as myelodysplastic syndromes and multiple myeloma. Whether IMiDs may improve the efficacy of current standard treatment in AML remains understudied. Here, we have exploited in vitro and in vivo preclinical AML models to analyze whether IMiDs potentiate the efficacy of AraC/Idarubicin-based standard AML chemotherapy by interfering with the BM stroma-mediated chemoresistance. We report that IMiDs do not exert cytotoxic effects on either non-del5q/5q- AML cells nor BM-MSCs, but they enhance the immunomodulatory properties of BM-MSCs. When combined with AraC/Idarubicin, IMiDs fail to circumvent BM stroma-mediated resistance of non-del5q/5q- AML cells in vitro and in vivo but induce robust extramedullary mobilization of AML cells. When administered as a single agent, lenalidomide specifically mobilizes non-del5q/5q- AML cells, but not healthy CD34+ cells, to peripheral blood (PB) through specific downregulation of CXCR4 in AML blasts. Global gene expression profiling supports a migratory/mobilization gene signature in lenalidomide-treated non-del5q/5q- AML blasts but not in CD34+ cells. Collectively, IMiDs mobilize non-del5q/5q- AML blasts to PB through CXCR4 downregulation, but fail to potentiate AraC/Idarubicin activity in preclinical models of non-del5q/5q- AML.

The popular food, dairy products like curds are consumed by many people in its various forms in Bangladesh. Infact, these different types of curds are made without real respect for basic standards of technology and hygiene. This situation will be improved if lactic ferments are well-identified and their synergy taken into consideration. Not much information has been reported about the Lactobacilli species responsible for curd production in Bangladesh. In this context, this study was conducted to identify and characterize lactic acid bacteria in curds to provide scientific data needed for improvement of the fermented product. Twenty samples were collected from the producers of curds in the supermarket of Shaheb Bazar, Rajshahi. The culture media used were Czapek Dox (pH 5.3), M17, MRS and nutrient broth and agar for the investigation of lactic acid bacteria. The identified lactic acid bacteria were Lactobacilli including Lactobacillus casei (sample 1), Lactobacillus delbrueckii (sample 3), Lactobacillus plantarum (sample 4) and Lactobacillus helveticus (sample 6) based on morphological characteristics, catalase activities, milk coagulation, growth at different temperature, growth in medium with different NaCl concentrations, growth at Original Research Article

Concentrating solar power technologies are potential energy-harvesting systems. This paper simulates and analyzes the design of a parabolic-trough concentrating solar system. Optimum measurements are sought for the receiver, and collector performance is investigated using three heat transfer fluids, namely, ammonia, nitrogen, and carbon dioxide. Receiver parameters are optimized to achieve the maximum thermal efficiency of the collector. The concentration ratio, collector aperture area, and mass flow rate of the fluids significantly influenced the collector's efficiency and the heat removal factor.

Developing countries depend mostly on natural fuel sources such as wood fuel, fossil fuel (kerosene and liquid petroleum gas) etc. for cooking purpose. However, these are expensive and also lead to the threads like deforestation as well as environmental degradation. An alternative renewable energy source like solar energy can contribute a solution towards the adverse crisis of fuel consumption along with environmental pollution of developing countries. Therefore, this study aims to design and fabricate a cost effective solar cooker for domestic purposes as well as performance analysis in order to evaluate its effectiveness. The cooker has been made of cardboard, tin, aluminum foil (polished and non-polished) and glass. Simple construction with reflectors surrounded by tin was fabricated with 1000ml load of water in the cooker hanging by a stand and observed that the best comparative performance in areas with longest durations of clear sky greatest direct ray falling on the collector cookers under moderate...

Detailed results of edge plasma and neutral particle behavior are described in the gas puff imaging experiments performed in the GAMMA 10 tandem mirror for the first time. Visible imaging measurement by using a high-speed camera (Ultima-SE, Photron Inc.) was recently performed in the central-cell midplane of GAMMA 10. In the standard plasma discharge heated by ICRF wave, a short gas puff of hydrogen (3 ms) was carried out and the time evolution of light emission was visualized precisely. It was found that the time evolution of the emission cloud was similar to that of Hα line intensity measured nearby and was localized close to the gas puff port. Asymmetry in diffusion of the emission cloud is observed radial and axial direction of plasma column in the central-cell. This localization phenomenon of neutrals is qualitatively well explained by a fully 3-dimensional simulation using DEGAS neutral particle transport code.

Results of Hα measurement in the GAMMA 10 tandem mirror are described, with a particular focus on the behavior of neutrals in the anchor minimum-B region. Recently a set of Hα line-emission detector arrays was designed and installed in the anchor-cell, where the shape of the magnetic flux tube becomes flat and the cross section of plasma is elongated elliptically. The detector consists of Hα interference filter, optical fiber, and photomultiplier with magnetic shield, and is absolutely calibrated by using a standard lamp. In standard ion-cyclotron-range-of-frequency heated, hot-ion-mode plasmas, detailed measurements of Hα line-emission form the central-cell to the anchor-cell were carried out, and the dependence of the Hα intensity on the quantity of gas puffing was investigated. The characteristic behavior of neutrals in the nonaxisymmetric anchor-cell is also discussed, based on the result of neutral transport simulation.

Details of service receipt by 132 people diagnosed with dementia and their carers were collected in South London (boroughs of Lewisham, Camberwell, Southwark and Croydon), a geographical area served by several health and social care providers. The data collected included the Caregiver Activity Survey, which details the informal care given. This paper reports the formal and informal services received by the people with dementia at entry to the study. The amount of time spent on specific caring tasks by all informal carers of people with dementia averaged seven hours per week, but was significantly higher for co-resident carers, even when controlling for the level of dependency of the person cared-for. The odds ratios of receipt of formal services are given, according to where people were living: in the community or residential care, with co-resident carers or alone.

Power is the driving tool for modernization of the world. Upraised fossil fuel prices and environmental issue drive the world to searching alternative option for producing power. In such case, solar energy appears as the most attractive option due to its abundancy and clean feature. Today solar thermal technologies are the most popular advanced techniques. The performance of solar thermal technologies depends on some factors. Among these factors, thermo fluids have very crucial role in power producing through effective usage of solar thermal energy. System efficiency depends on temperature of thermo fluids. So, thermo fluids used in power generation is an important concern. This article accumulates latest literatures in terms of thesis, journal articles, reports, etc on thermo fluids for solar power generation. However, this review article shows that performance of solar thermal system can be improved by utilizing appropriate thermo fluid.

We newly designed and installed a Hα line-emission detector in order to examine neutral particle transport around the beam line of NBI in the central cell of the GAMMA10 tandem mirror. The Hα detector consists of a Hα interference filter, a lens, an optical fiber, and a photomultiplier. The detector is absolutely calibrated using a standard lamp. The Hα detector is located at the angle of 24° to the beam line, which enabled us to directly view the Hα emission due to neutral beam injection (NBI). In standard hot-ion mode plasmas, we measured the Hα line emission in the case of NBI. The Hα line emission during NBI strongly increased by 550% on the beam line compared with that before NBI. Moreover, it was found that hydrogen recycling played an important role in the neutral transport around the beam line. This diagnostic system is confirmed to be considerably helpful for examining the detailed behavior of the neutral particles related to NBI for the first time.

Study of plasma shape by movable Langmuir probes at the transition region of anchor cell points out the displacement of plasma from magnetic flux tube. Measurements of edge plasma near the conducting plates indicate the ion loss through the transition regions. It is suggested that ⊇B and curvature drifts are the sources of plasma displacement and ion loss. Possible ways of the improvement of GAMMA 10 magnetic field configuration are discussed.

Communication during the disaster is a difficult issue. The disaster may be natural like tsunami, hurricane, cyclones or man-made like terrorist attack, massive power failure or wartime scenario. The high bandwidth supporting technology is evolving very fast, leading us from 4G/LTE to 5G/cognitive devices' regime. Unfortunately all these technology are badly dependent on the infrastructure. In case the infrastructure is collapsed or handicapped, communication is no more possible. As a result disaster time critical communication is also very vital with very limited data (like message or signal etc.). This paper proposes a novel handheld mobile device that utilizes 1) the existing GNSS location service via Beidou and 2) MANET routing via OLSR protocol. The additional sms feature offered by Beidou enables the proposed device to communicate during emergency rescue operation to find affected people's location and information. Simulation in an assumed test scenario shows suitability of the proposed device.

This paper presents a multiple kernel learning (MKL) approach to speech/music discrimination (SMD). The time-frequency representation (spectrogram) implemented by short-time Fourier transform (STFT) of audio segment is decomposed by wavelet packet transform into different subband levels. The subbands, which contain rich texture information, are used as features for this discrimination problem. MKL technique is used to select the optimal subbands to discriminate the audio signals. The proposed MKL based algorithm is applied for SMD of a standard dataset. The experimental results show that the proposed technique yields noticeable improvements in classification accuracy and tolerance toward different noise types compared to the existing methods.

we show theoretically that the pulse instability in the figure-8 laser can be removed by introducing intentional twist in the fibre, which provides a controllable birefringence-induced phase-bias. In the later section, we verify the proposed theory experimentally. We also show that such a stabilized laser can generate very stable dual wavelength pulses with the wavelengths tunable by simply adjusting the polarization controllers in the two loops. Wavelength tuning in single wavelength operation and wavelength separation and relative amplitude tuning are demonstrated in dual wavelength operation. Furthermore, the polarization of the pulses at each wavelength is orthogonal to the other.

A three-dimensional neutral transport model using the DEGAS version 63 Monte Carlo code is described in order to understand the behavior of neutrals in the non-axisymmetric anchor region of the GAMMA 10 tandem mirror. A precise mesh structure with three-dimensional geometry was built up and the simulation was carried out under a plausible assumption of the particle source on the basis of experimental data. In standard ion-cyclotron-range-of-frequency heated plasmas, detailed measurements of H α line emission were performed using a 5-ch H α detector array in the outer-transition region of the east anchor cell and the experimental results were compared with tlie simulation. The spatial profile of H α emission predicted from the simulation agreed well with the experimental result and the distinctive behavior of neutrals in this region was clarified.

The instability of a high-frequency wave, such as the Langmuir wave (LW) is studied using a Vlasov-kinetic model in streaming and irradiated dusty plasma with dust charge fluctuation. In irradiated dusty plasma, dust charge fluctuation is considered to be due to the combined effect of LW perturbation and photoelectron emission. It is found that the dust charge fluctuation makes tlie LW unstable and this instability linearly adds to the Landau effect, Growth rate of the instability of LW is discussed. Discussion is also given to justify the theory and to verify it in the laboratory experiment.

The effect of polarization mode dispersion PMD remains a central consideration in the practical development of a universal commu- nication system. A huge number of measurements of polarization mode dispersion have been recorded for single-mode fibers SMFs, but the white-light interferometry setup used by our research group has yielded more relevant quantitative results, not only for SMFs but also encom- passing polarization-maintaining fibers and suggesting devices to cope with the complex scenarios of communication. The setup is unique in measuring PMD for single-mode and highly birefringent specialty fibers. Useful application results have been achieved for different light sources, which reflect exact measurements and their comparison for effective ap- plication in the field of communication and precision characterization of the optical fiber. © 2006 Society of Photo-Optical Instrumentation Engineers.

The role of omentum with or without antibiotic administration was evaluated in the healing of external wounds in goats. Nine goats aged 8-10 months and weighing 7-8 kg was randomly allocated into 3 groups as A: treated with omentum, B: omentum plus antibiotic and C: control. Experimental wounds about 2.5 cm long and 0.5 cm deep was produced on each side of the midline at the lumber region in each goat. Omentum 2 cm long and 0.4 cm wide obtained from an abattoir were lodged between the wound edges and apposed with nylon thread by simple interrupted suture. Complete healing was obtained on 11, 13 and 19 days in groups B, A and C, respectively. Rectal temperature, heart and respiratory rates showed no significant (p>0.05) variation during the healing period. On histopathological studies, highest degree of inflammation was observed in group C till day 15, but on day 5 in groups A and B. The rates of fibrosis of collagen fibre, epithelialization and neo-vascularization were most intensive in group B and then in group A and C till day 10. It is suggested that omentum along with antibiotic showed good healing in goats. DOI: 10.3329/bvet.v25i1.4612 Bangl. vet. 2008. Vol. 25, No. 1, 1-8
