OBJECTIVE

Endovascular thrombectomy in patients with acute ischemic stroke caused by occlusion of the proximal anterior circulation arteries is superior to standard medical therapy. Stentriever thrombectomy with or without aspiration assistance was the predominant technique used in the 5 randomized controlled trials that demonstrated the superiority of endovascular thrombectomy. Other studies have highlighted the efficacy of a direct aspiration first-pass technique (ADAPT).

METHODS

To compare the angiographic and clinical outcomes of ADAPT versus stentriever thrombectomy in patients with emergent large vessel occlusions (ELVO) of the anterior intracranial circulation, the records of 134 patients who were treated between June 2012 and October 2015 were reviewed.

RESULTS

Within this cohort, 117 patients were eligible for evaluation. ADAPT was used in 47 patients, 20 (42.5%) of whom required rescue stentriever thrombectomy, and primary stentriever thrombectomy was performed in 70 patients. Patients in the ADAPT group were slightly younger than those in the stentriever group (63.5 vs 69.4 years; p = 0.04); however, there were no differences in the other baseline clinical or radiographic factors. Procedural time (54.0 vs 77.1 minutes; p < 0.01) and time to a Thrombolysis in Cerebral Infarction (TICI) scale score of 2b/3 recanalization (294.3 vs 346.7 minutes; p < 0.01) were significantly lower in patients undergoing ADAPT versus stentriever thrombectomy. The rates of TICI 2b/3 recanalization were similar between the ADAPT and stentriever groups (82.9% vs 71.4%; p = 0.19). There were no differences in the rates of symptomatic intracranial hemorrhage or procedural complications. The rates of good functional outcome (modified Rankin Scale Score 0–2) at 90 days were similar between the ADAPT and stentriever groups (48.9% vs 41.4%; p = 0.45), even when accounting for the subset of patients in the ADAPT group who required rescue stentriever thrombectomy.

CONCLUSIONS

The present study demonstrates that ADAPT and primary stentriever thrombectomy for acute ischemic stroke due to ELVO are equivalent with respect to the rates of TICI 2b/3 recanalization and 90-day mRS scores. Given the reduced procedural time and time to TICI 2b/3 recanalization with similar functional outcomes, an initial attempt at recanalization with ADAPT may be warranted prior to stentriever thrombectomy.

Published: April 2017

Intracranial epidermoid cysts are benign lesions of epithelial origin that most frequently present with symptoms of mass effect. Although they are often associated with a high rate of residual tumor and recurrence, maximal safe resection usually leads to good outcomes. The authors report a complete resection of an uncommon pituitary stalk epidermoid cyst with intrasellar extension using a combined suprasellar and infrasellar interpituitary, endoscopic endonasal transsphenoidal approach. The patient, a 54-year-old woman, presented with headache, visual disturbance, and diabetes insipidus. Postoperatively, she reported improvement in her visual symptoms and well-controlled diabetes insipidus using 0.1 mg of desmopressin at bedtime and normal anterior pituitary gland function. One year later, she continues to receive the same dosage of desmopressin and is also taking 50 mcg of levothyroxine daily after developing primary hypothyroidism unrelated to the surgical procedure. A combined infrasellar interpituitary and suprasellar approach to this rare location for an epidermoid cyst can lead to a safe and complete resection with good clinical outcomes.

Published: April 2017

OBJECTIVE

In this paper, the authors set out to identify the angiographic features of moyamoya disease with posterior hemorrhage, which is a strong predictor of rebleeding.

METHODS

This cross-sectional study used the data set of the Japan Adult Moyamoya Trial (clinical trial registration no.: C000000166 [www.umin.ac.jp/ctr/index.htm]). The panel designed the ancillary measurement of angiography at onset, classifying the collateral vessels into 3 subtypes: lenticulostriate anastomosis, thalamic anastomosis, and choroidal anastomosis. The association between each collateral and the hemorrhage site (anterior vs posterior) was assessed in the hemorrhagic hemisphere by using multivariate adjustment for potential confounders, including age, sex, and involvement of the posterior cerebral artery (PCA). The association was confirmed through topographical analysis of bleeding points.

RESULTS

Among the 80 participants, 75 hemorrhagic hemispheres of 75 patients were analyzed. Lenticulostriate anastomosis was detected in 21 (28.0%) hemorrhagic hemispheres, thalamic anastomosis in 22 (29.3%), and choroidal anastomosis in 35 (46.7%). Choroidal anastomosis was a factor associated with posterior hemorrhage (OR 2.77 [95% CI 1.08–7.10], p = 0.034) and remained statistically significant after the multivariate adjustment (OR 2.66 [95% CI 1.00–7.07], p = 0.049). PCA involvement was also associated with posterior hemorrhage in both univariate and multivariate analyses. Topographical analysis revealed good correspondence between bleeding points associated with positive choroidal anastomosis and the anatomical distribution of the choroidal arteries, including the thalamus and the wall of the atrium.

CONCLUSIONS

Choroidal anastomosis and PCA involvement are characteristic of posterior hemorrhage in moyamoya disease. Choroidal anastomosis might be considered a potential source of posterior hemorrhage at high risk of rebleeding.
Intracranial pressure in patients undergoing decompressive craniectomy: new perspective on thresholds
Authors: Sauvigny Thomas , Göttsche Jennifer , Czorlich Patrick , Vettorazzi Eik , Westphal Manfred , Regelsberger Jan
Published: April 2017

OBJECTIVE

Decompressive craniectomy (DC) is an established part of treatment in patients suffering from malignant infarction of the middle cerebral artery (MCA) or traumatic brain injury (TBI). However, no clear evidence for intracranial pressure (ICP)-guided therapy after DC exists. The lack of this evidence might be due to the frequently used, but simplified threshold for ICP of 20 mm Hg, which determines further therapy. Therefore, the objective of this study was to evaluate this threshold's accuracy and to investigate the course of ICP values with respect to neurological outcome.

METHODS

Data on clinical characteristics and parameters of the ICP course on the intensive care unit were collected retrospectively in 102 patients who underwent DC between December 2007 and April 2014 at the authors' institution. The postoperative ICP course in the first 168 hours was recorded and analyzed. From these findings, ICP thresholds discriminating favorable from unfavorable outcome were calculated using conditional inference tree analysis. Additionally, survival analysis was performed using the Kaplan-Meier method. Prognostic factors were assessed via univariate analysis and multivariate logistic regression. Favorable outcome was defined as a score of 0–4 on the modified Rankin Scale.

RESULTS

Multivariate logistic regression revealed that anisocoria, diagnosis, and ICP values differed significantly between the outcome groups. ICP values in the favorable and unfavorable outcome groups differed significantly (p < 0.001), while the mean ICP of both groups lay below the limit of 20 mm Hg (17.5 and 11.5 mm Hg, respectively). These findings were reproduced when analyzing the underlying pathologies of TBI and MCA infarction separately. Based on these findings, optimized time-dependent threshold values were calculated and found to be between 10 and 17 mm Hg. These values significantly distinguished favorable from unfavorable outcome and predicted 30-day mortality (p < 0.001).

CONCLUSIONS

This study systematically evaluated ICP levels in a long-term analysis after DC and provides new, surprisingly low, time-dependent ICP thresholds for these patients. Future trials investigating the benefit of ICP-guided therapy should take these thresholds into consideration and validate them in further patient cohorts.

Published: April 2017

OBJECTIVE

Endoscopic strip craniectomy (ESC) with postoperative helmet orthosis is a well-established treatment option for sagittal craniosynostosis. There are many technical variations to the surgery ranging from simple strip craniectomy to methods that employ multiple cranial osteotomies. The purpose of this study was to determine whether the addition of lateral barrel-stave osteotomies during ESC improved morphological outcomes.

METHODS

An IRB-approved retrospective review was conducted on a consecutive series of cases involving ESC for sagittal craniosynostosis at 2 different institutions from March 2008 to August 2014. The patients in Group A underwent ESC and those in Group B had ESC with lateral barrel-stave osteotomies. Demographic and perioperative data were recorded; postoperative morphological outcomes were analyzed using 3D laser scan data acquired from a single orthotic manufacturer who managed patients from both institutions.

RESULTS

A total of 73 patients were included (34 in Group A and 39 in Group B). Compared with Group B patients, Group A patients had a shorter mean anesthetic time (161.7 vs 195 minutes; p < 0.01) and operative time (71.6 vs 111 minutes; p < 0.01). The mean hospital stay was similar for the 2 groups (1.2 days for Group A vs 1.4 days for Group B; p = 0.1). Adequate postoperative data on morphological outcomes were reported by the orthotic manufacturer for 65 patients (29 in Group A and 36 in Group B). The 2 groups had similar improvement in the cephalic index (CI): Group A, mean change 10.5% (mean preoperative CI 72.6, final 80.4) at a mean follow-up of 13.2 months; Group B, mean change 12.2% (mean preoperative CI 71.0, final 79.6) at a mean follow-up of 19.4 months. The difference was not statistically significant (p = 0.15).

CONCLUSIONS

Both ESC alone and ESC with barrel staving produced excellent outcomes. However, the addition of barrel staves did not improve the results and, therefore, may not be warranted in the endoscopic treatment of sagittal craniosynostosis.

Published: April 2017

Background: Recent genetic and epidemiological studies have shown that there is a link between essential tremor and Parkinson’s disease (PD). However, there is a lack of data about the clinical features of PD developed from essential tremor.

Objective: To explore and describe the clinical characteristics of Parkinson’s disease developed from essential tremor (ET-PD).

Methods: Twenty-five ET-PD patients and 124 IPD controls were enrolled according to each criterion. Motor and non-motor features and dopamine transporter uptake were compared between the two groups.

Results: Rest and action tremors were more severe in ET-PD patients than in IPD patients. In addition, tremor disorder of first-degree relatives occurred more frequently in the ET-PD group than in the IPD group. A comparison between cases with ET-PD and IPD was not significant for striatal dopamine transporter uptake. Among the non-motor features, sleep disorder frequency, especially rapid-eye-movement sleep behavioral disorder, were lower in patients with ET-PD than in those with IPD, and smell identification test scores were higher in patients with ET-PD than in those with IPD. The prevalence of other non-motor symptoms did not differ between the two groups.

Conclusion: This is the first comparison of motor and non-motor features between ET-PD and IPD. ET-PD and IPD have different characteristic motor and non-motor features from the nosologic perspective.
Effect of somatic cell count on dairy products: a review
Authors: Talukder Mukta , Ahmed HM Manir
Published: April 2017

Somatic cells are the most essential factors naturally present in milk, and somatic cell count (SCC) is used as an indicator of monitoring mastitis incidence in the herd and also to assess the quality of milk. In addition, SCC is frequently used to determine quality payments to dairy producers. The SCC is directly related to get maximum milk production from individual cow and a lower SCC indicates better animal health, as somatic cells originate only from inside the animal's udder. SCC monitoring is important because as the number of somatic cells increases, milk yield is likely to fall, primarily due to the damage to milk-producing tissue in the udder caused by mastitis pathogens and the toxins they produce, particularly when epithelial cells are lost. Keeping low SSC will allow good quality more raw milk and provide a better product to milk processors whether used as fluid milk or converted to milk based products. Somatic cells containing lipolytic and proteolytic enzymes lead to degrade major nutrients fats and proteins, respectively. Elevated SCC is related to udder inflammation, which leads to alter the normal microbial count and physicochemical parameters of milk, as well as the quality of heat treated fluid milk and milk based product. The objective of this review is to discuss on the SSC and endogenous enzymes released from somatic cells in raw milk as well as effect of somatic cells count and their endogenous enzymes in processed milk and milk based products.Asian J.

Published: April 2017

Genotypes x environment interaction as well as stability of performance were determined for grain yield and yield contributes of 12 wheat genotypes under four salinity levels of environments (control, 8, 12, 16 dS/m). Significant genotype-environment interaction (linear) for days to heading, plant height, number of spikes per plant and grains per spikes, 1000-grain weight and grain yield per plant at 1% level of probability when tested against pooled deviation. Both the environment (linear) and genotype x environment (linear) components of variation for stability were also significant indicating that prediction of the genotypes on the environment appeared feasible for all the characters. The variance due to pooled deviation was significant for only days to heading. Considering all the three stability parameter, genotype G11 was found most stable among all the genotypes for grain weight of wheat. Among the genotypes G11, G22, G24, G33 and G40 were most desirable for yield per plant. The genotype G32 showed more responsiveness to changing environment and was suited only for highly favorable environments. Based on three stability parameters, G11, G22 and G37 were the most stable and desirable genotypes with reasonable good yield among the all.Asian J. Med. Biol. Res. March 2017, 3(1): 38-43

The study was conducted aiming at the isolation and identification of pathogens from poultry feed manufactured by four different brands namely A (broiler starter), B (broiler finisher), C (layer starter) and D (layer finisher) sold in retail stores of Rangpur city of Bangladesh. All these samples were collected from four randomly chosen outlets and analyzed by culturing in different culture media such as Nutrient broth (NB), Nutrient agar (NA), Salmonella-Shigella (SS) agar, Eosin methylene blue (EMB) agar, MacConkey agar, Triple sugar iron (TSI) agar slant, Motility, Indole, Urease (MIU) and Saboraud Dextrose agar (SDA) media. The bacterial agents were isolated and examined under light microscope for their gross morphological and conventional biochemical characteristics. The bacteriological analyses were done at the Microbiology Laboratory of Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of January to June, 2014. Total bacterial colonies of all the samples were counted separately according to the American Public Health Association, using nutrient agar medium for total viable count (TVC), Eosine methylene blue (EMB) agar media for total E. coli count (TEC) and Salmonella-Shigella agar for TSC (total salmonella count). Saboraud Dextrose agar (SDA) media was used for detection of fungus. The virulence effect of the organism present in feed were observed by inoculating the organism in poultry. Recorded result showed that average TVC of feed sample A, B, C and D were 5.45x106, 3.28x105, 5.14x106 and 4.53x105 CFU/gm (colony forming unit per gram) respectively. TEC of feed sample A, B, C and D were recorded 6.25x105, 8.26x103, 5.52x105 and 5.65x104 CFU/gm respectively. TSC of feed sample A, B, C and D were recorded 3.15x104, 2.68x103, 4.46x103 and 1.19x104 CFU/gm respectively. The highest TVC, TEC and TSC were found in broiler starter (feed sample A) and lowest TVC, TEC and TSC were found in broiler finisher (feed sample B). Fungal count was 1.85x105 CFU/ gm in layer finisher (feed sample D) could be as a result of their high pathogenecity as reported by researchers elsewhere. These organisms can cause several poultry and farm animal infections specially mycotoxicosis having public health significance to both human and poultry. The presence of high numbers of E. coli and Salmonella spp. in poultry feed were indicative of poor hygienic practices during manufacture, post process contamination and unsatisfactory transportation and reservation. Therefore reinforce the need for preventive control measures, hygienic handling and processing of feeds to reduce the risk of potential human health hazards.Asian J. Med. Biol. Res.

Published: April 2017

The survey was carried out to get present status of farmers, housing profile and feeding management of Black Bengal Goats. The study was performed in four districts of northern region of Bangladesh, namely Bogra, Sirajganj, Gaibandha and Rangpur. Middle aged people were more interested in rearing goat both traditional (53.75%) and commercial (60%) farming system. Males (100%) were dominant in commercial system and females (63.75%) in traditional farming system. Most of the traditional farming farmers houses were earthen wall (76.25%) and non paved floor (71.25%). Brick wall (50%) and slatted floor (66.67%) were practiced more in commercial farming. Hundred percent farmers of commercial farming system constructed their farm away from own residence and (77.25%) traditional farming farmers house were attached with their own house without maintaining proper direction and ventilation system. 85% farmers of traditional approaches provided roadside and fallow land grasses by tethering feeding system and all commercial farming farmers cultivated fodder and fed by cut and carry feeding system after processing. Most of the traditional farming farmers (85%) did not provide any kind of concentrate mixture to their goats. In commercial farming approaches all goats were fed concentrate feed through homemade or purchased readymade feed from market. Drinking water sources of tube well (48%) and pond (49.25%) were interchangeable in traditional farming and tube well water was the main source in commercial farming approaches. In conclusion, both traditional and commercial farming approaches are practiced for goat production in northern districts of Bangladesh. This housing and feeding management for goat production are absolutely unclear. So, this study will support researchers and extension workers to develop proper strategic policies and help to take correct steps for future betterment of the Black Bengal Goats raising farmers.Asian J.

Pure breeding is necessary for the conservation and improvement of indigenous chicken genetic resources. Present research is a part of the long-term selection program being undertaken to evaluate the performance and expected response to selection of first generation (G1) of three indigenous chicken genotypes under intensive management in Bangladesh. A total of 1439-day-old chicks comprising of 3 genotypes namely Naked Neck (NN), Hilly (H) and Non-descript Desi (ND) were hatched for this study. In first generation (G1), selection was practiced on body weight at 8 and 16 weeks of age, on the basis of their breeding value. At 40-week of age, selection will be practiced on the basis of an index comprising the parameters of age at first egg (ASM), body weight (BW), egg production (EP) and egg weight (EW). At 8, 10 and 12 weeks of age, six birds from each genotype were slaughtered to analyze the meat yield traits. Data were analyzed in CRD by General Linear Model Univariate Procedure. Significantly (P<0.001) highest body weight of day-old chicks (28.65±0.12 g) and daily weight gain in all stages were found in H genotype than other two genotypes. Although there was significant (P<0.001) difference in live weight between ages at slaughter, dressing percent (65.87 - 66.89 %) of different ages was similar (P>0.05) but was affected (P<0.001) by genotype. Body weight at 8 weeks of age was expected to improve by 58.98 vs. 11.50; 81.56 vs. 40.91 and 53.81 vs. 15.82 g; respectively for ND, H and NN males and females. In terms of body weight and growth traits H genotype was superior and NN genotype was for dressing percentage. As a result of selection; chick weight, body weight at all stages increased and ASM reduced in first generation than foundation stock. These findings give an impetus for continuing the pure breeding research for more generations.Asian J. Med. Biol. Res. March 2017, 3(1): 72-79

Published: April 2017

The investigation was conducted in the Molecular Horticulture Laboratory of Agrotechnology Discipline, Khulna University to develop processed products from jackfruit through their sensory evaluation in order to see their suitability and consumer acceptability. Using variation in sugar contents five preparations of raw jackfruit green pickle, four preparations of rind jelly and bulb jelly, and three preparations of jam, squash and sweet pickles were successfully prepared. Results from sensory evaluation using a seven point hedonic scale to rate for color, taste, flavor, texture and overall acceptability by untrained panelists indicated preparation No. 3 of green pickle, preparation No. 3 and 4 of rind jelly, preparation No. 2 of bulb jelly, jam, squash and sweet pickle scored highest among all the preparations. The storage of these products in normal room temperature showed that produced pickles remain unchanged even after 12 months of storage. But the quality of jam, jelly and squash started to deteriorate after 7 months of storage due to the absence of preservatives. Based on results, it can be concluded that commercial production of the products by using different parts of jackfruit can be taken up and promoted as a small scale income generating activity.J.

A Possible Approach for Maintaining Effective Omega-6/ Omega-3 Fatty Acid Ratio from Mixed Vegetable Oils
Authors: Haque MM , Rahman MN , Alam MJ , Akter S
Published: April 2017

Vegetable oil rich in omega-3 and omega-6 fatty acids is an important element in the diet of most transitional countries. The ratio of omega-6 to omega-3 in modern diets is approximately 15:1, whereas ratios of 2:1 to 4:1 have been associated with reduced mortality from cardiovascular disease, suppressed inflammation in patients with rheumatoid arthritis, and decreased risk of breast cancer. The study was designed to investigate the fatty acid profile of six types of seed oils such as peanut, linseed, olive, soybean, sesame and sunflower oil. Afterwards the author prepared mixed vegetable oils with effective Omega-6 (n-6)/omega-3 (n-3) fatty acid ratio. It was found that the highest percentage (39.9%) of saturated fatty acid found in Linseed oil and the highest percentage (37.1%) of monounsaturated fatty acid found in Sesame oil. It was also observed that olive and soybean oil contain 100% polyunsaturated fatty acid and the lowest percentages (35.2%) of polyunsaturated fatty acid were found in Sesame oil. After preparing a mixed vegetable oil  The ratio of n-6 to n-3 were 3.5:1 (soybean), 19:1 (olive), 0.43:1 (linseed), 0.13:1 (peanut) and sesame (16.5:1). It is also noted that n-3 was not detected in sunflower oil. Thus the investigation showed that Soybean oil contains the balanced omega-6/omega-3 fatty acid ratio than others.J. Environ.

The experiment was laid out in randomized complete block design (RCBD) with six (6) irrigation treatments. Two treatments, T1 and T3 were kept under continuous standing water levels (10 cm and 5 cm respectively) while in treatment T5 irrigation water was supplied for 1st 3 weeks then followed mid season drain out and re-flooded at flowering stage. Three alternate wetting and drying irrigation treatments, T2, T4 and T6 were selected in which irrigation water was applied when water level dropped 20cm, 10cm and 15cm below ground level, respectively. All the irrigation treatments significantly affected the rice yield and yield contributing parameters. The study revealed that the highest grain yield (5950 kg ha-1) was found in treatment T5 which was identical with AWDI treatment T4 (5820 kg ha-1) followed by AWDI treatment T6 (5460 kg ha-1). On the contrary, rice yield of 3350 kg ha-1, 4470 kg ha-1 and 4810 kg ha-1 were found in the treatment T1, T2 and T3, respectively. It was found that AWDI treatment T2 showed maximum water savings (15.1%) followed by T6 (11.3%), T4 (7.59%) and T5 (3.8%), however rice yield in the treatment T2 (4470 kg ha-1) was significantly lower compared to T6, T4 and T5 treatment. Therefore, it may be inferred that treatment T4 (AWDI; irrigation when water level fell 10 cm from ground level), T5 (Irrigation for 1st 3 weeks, then mid-season drain out and re-flooding at flowering) and T6 (AWDI; irrigation when water level fell 15cm from ground level) would be the feasible choice for the water savings, higher rice yield as well as maximum water productivity index (0.478, 0.472 and 0.467, respectively) for sustaining rice farming during the dry Boro season in Bangladesh.J.

Soil quality is essential for sustainable crop production. Excessive or deficient in necessary chemical elements in soil is a concern for soil quality. The study was undertaken to evaluate the impact of chemical industrial wastewater on chemical properties of soil and observe spatial distribution of nutrients in paddy soil adjacent to a chemical industry. A command area comprising a paddy field exposed to a chemical industrial wastewater was selected to study and 10 composite soil samples including a control (not exposed to wastewater) was collected and analyzed. Compared to background values soil pH, OC, N, P, Ca, and S were found higher in contaminated soils through the industrial wastewater. The order of the increment of the nutrients in the contaminated soil was as N>P>S>OC>Ca>Na. Sulphur and Nitrogen pose as potent elements for toxicity or pollution of the soil exposed to untreated wastewater. Differential spatial variations were observed for various nutrients in the area. Highest spatial variation was observed for S, N and B followed by P, K, Ca, Mg and Na might be due to anthropogenic activities through industrial untreated wastewater. These issues need to be taken into consideration while recommending fertilizers for crops grown in this type of command area.J. Environ. Sci. & Natural Resources, 9(2): 85-90 2016

This study was conducted to know the status of physicochemical water quality parameter and heavy metal concentration in the water of Buriganga river, adjoining to Dhaka city. Water samples were collected from five different points of Buriganga river and were analyzed to determine pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), chromium (Cr), lead (Pb), cadmium (Cd), copper (Cu) and manganese (Mn) content. Most of the measured water quality parameters and concentration of heavy metals were exceeded the standard level set by ECR and ADB. Among heavy metals concentration, level of chromium and cadmium were 4-5 times higher than the standard drinking level, these results indicate that surrounding industrial wastewater discharging from textile and tannery industries, which pollute the Buriganga river water. During the observation, at Hazaribagh station BOD level was found 32 times higher than drinking water standard level and 6 times higher than standard irrigation level, indicating Buriganga river water is extremely polluted by microorganism and is not suitable for household and irrigational use. Similarly, DO level at Buriganga river water was 5 times lower than the standard level, which indicates that Buriganga river water is extremely polluted and is unsuitable for aquatic life which are dependent on DO for their sustain. In the present study, the measured level of EC, chromium, cadmium and copper were found higher level as compare to the previous studies.J. Environ. Sci. & Natural Resources, 9(2): 97-104 2016

To develop a database on growth promoters and feed additives in cattle fattening a purposive survey was carried out. It is done among 30 cattle fattening farmers covering 1 Upazilla under 3 union in Mymensingh district of Bangladesh, who were involved in cattle fattening activities before Eid-Ul-Azha (August to November2015). The survey was done covering farmers information, livestock population and production system, feed sources, manpower involvement, availability, types of hormones, feed additives use with negative opinion and probable suggestions for controlling whereas the researcher had no control or could not manipulate the variables as the appeared. All the farmers interviewed during the survey period were literates, and about 52% of them had primary education, 27% had secondary school certificates, 14% obtained higher secondary certificate and the rest were graduates and post-graduates, 7%. Irrespective of literacy about 10% of the interviewed farmer had training on cattle fattening and the rest fattened cattle without having any sort of training. About 35% respondents use skilled personal for cattle fattening. In the study areas, most of the farmers (55%) were using roughage and 45% of them use concentrate. The fattened cattle were marketed by farmers is 98% and rest 2% by butcher or others. About 72% of the farmer use Tracoll and 28% use Ketofox as feed additives and as hormone 30% farmers use Betamethasone, 55% use Decasone and 15% use Periactin. In public perception 89% farmers use growth promoters in wrong period and 80% use harmful feed additives, feeding natural feed in low amount is (65%). Consumers are less concern to buy fattened bull (93%). The mean of the suggestions like veterinary services (1.26), doses in proper ages (2.06), feeding balanced feed (1.62), organic growth promoters program (0.60) and knowledge through ICT program (0.03). From the above results it may be concluded that, major number of cattle are fattened by small farmers in the survey area. For this fattening purpose different types of hormones and feed additives available in the market are used by them. It can be concluded that, the percentages of different negative opinions on using hormones and feed additives is higher.J. Environ. Sci. & Natural Resources, 9(2): 109-113 2016

The experiments were carried out to assess the quality of mango at different ripening stages. The two factor experiment was laid out in completely randomized design (CRD) with three replications. The experiment comprised four varieties, viz., V1: BAU Aam-1, V2: BAU Aam-6, V3: BAU Aam-7, V4: BAU Aam-8 and five ripening stages. Among the attributes total weight loss, dry matter content, total soluble solids (TSS), sugar content (total, reducing and non-reducing), disease incidence increased, while the moisture, vitamin C contents and titratable acidity decreased with the increase in duration of storage. Among the four varieties, BAU Aam-6 showed better results in relation to the most of the characters examined. Ripening stage-5 of mango fruit was observed to be the best among the five ripening stages in relation to the most of the chemical characters examined. Finally, it can be concluded that the results of this experiment will be useful with particular reference to quality control, preparation for transportation and marketing, and will also be beneficial for both the growers and consumers.J.

Published: April 2017

Impacts of sea level rise in Bangladesh were assessed using data from secondary sources. The review study reveals that one meter sea level rise will affect the vast coastal areas and flood plain zone of Bangladesh. Both livelihood options of coastal communities and the natural environment of the coastal areas will be affected by the anticipated sea level rise, which will also affect food security of the country. The ecosystem of the Sundarban mangrove forest will be totally lost with one meter rise in sea level. An integrated combined effort of Bangladesh Government, local people and International communities and stakeholders are indispensable for the survival of the coastal communities and ecosystem of southern areas of Bangladesh.J.

Solid waste management is now one of the big challenging issues in Bangladesh. With increasing population, volume of solid waste is increasing enormously. Production of biogas from organic solid waste is an environment friendly energy source as well as great management strategy of solid waste. The purpose of this current study is to determine the physicochemical composition of solid waste to determine the prospect of biogas production. Results reveal that, temperature and pH of the solid waste should be controlled for the maximum production of biogas. On the other hand, collected solid waste samples contained sufficient amount of moisture for the production of biogas. Appropriate temperature controlling system and buffer for pH maintenance can play a great role to maximize biogas production.J. Environ. Sci. & Natural Resources, 9(2): 151-154 2016

Adipose-derived mesenchymal stem cells (ASCs) release factors beneficial for islets in vitro and protect against hyperglycemia in rodent models of diabetes. Oxygen tension has been shown to induce metabolic changes and alter ASCs' release of soluble factors. The effects of hypoxia on the antidiabetic properties of ASCs have not been explored. To investigate this, we incubated human ASCs for 48 h in 21% (normoxia) or 1% O2(hypoxia) and compared viability, cell growth, surface markers, differentiation capability, and soluble factors in the conditioned media (CM). Human islets were exposed to CM from ASCs incubated in either normoxia or hypoxia, and islet function and apoptosis after culture with or without proinflammatory cytokines were measured. To test hypoxic preconditioned ASCs' islet protective effects in vivo, ASCs were incubated for 48 h in normoxia or hypoxia before being injected into Balb/c Rag 1-/-immunodeficient mice with streptozotocin-induced insulitis. Progression of diabetes and insulin content of pancreas were measured. We found that incubation in hypoxia was well tolerated by ASCs and that levels of VEGF-A, FGF-2, and bNGF were elevated in CM from ASCs incubated in hypoxia compared to normoxia, while levels of HGF, IL-8, and CXCL1 were reduced. CM from ASCs incubated in hypoxia significantly improved human islet function and reduced apoptosis after culture, and reduced cytokine-induced apoptosis. In our mouse model, pancreas insulin content was higher in both groups receiving ASCs compared to control, but the mice receiving preconditioned ASCs had lower random and fasting blood glucose, as well as improved oral glucose tolerance compared to untreated mice. In conclusion, our in vitro results indicate that the islet protective potential of ASCs improves in hypoxia, and we give insight into factors involved in this. Finally we show that hypoxic preconditioning potentiates ASCs' antidiabetic effect in vivo.
