Published: May 2021

BACKGROUNDMeningiomas are the most commonly encountered nonglial primary intracranial tumors. The authors report on the usefulness of intraoperative magnetic resonance imaging (iMRI) during microsurgical resection of meningiomas located close to eloquent areas or dural sinuses and on the feasibility of further radiation therapy.OBSERVATIONSSix patients benefited from this approach. The mean follow-up period after surgery was 3.3 (median 3.2, range 2.1–4.6) years. Five patients had no postoperative neurological deficit, of whom two with preoperative motor deficit completely recovered. One patient with preoperative left inferior limb deficit partially recovered. The mean interval between surgery and radiation therapy was 15.8 (median 16.9, range 1.4–40.5) months. Additional radiation therapy was required in five cases after surgery. The mean preoperative tumor volume was 38.7 (median 27.5, range 8.6–75.6) mL. The mean postoperative tumor volume was 1.2 (median 0.8, range 0–4.3) mL. At the last follow-up, all tumors were controlled.LESSONSThe use of iMRI was particularly helpful to (1) decide on additional tumor resection according to iMRI findings during the surgical procedure; (2) evaluate the residual tumor volume at the end of the surgery; and (3) judge the need for further radiation and, in particular, the feasibility of single-fraction radiosurgery.

Abstract
Purpose: comparison of electromyographic activity of quadriceps muscle in persons with unilateral traumatic transtibial amputation using patellar tendon bearing supracondylar endoskeletal prosthesis with the unaffected limb in weight bearing positions.
Method: 30 individuals aged 18-60 years were assessed using surface electromyography with functional level K3 according to K-level functional assessment scale to compare the activity of quadriceps of affected side using patellar tendon bearing supracondylar endoskeletal prosthesis with the unaffected side. The data was analysed using paired t-test.
Result: There was a significant difference in the activity of VMO and VLO muscles of the quadriceps in high sitting positions. There was also a significant difference in the activity of VMO muscle in single limb stance and bipedal stance. However, there was no significant difference between the activity of VLO muscle in bipedal stance but there was reduced activity of VLO muscle in the prosthetic limb in single limb stance.
Conclusion: The quadriceps activity was reduced in the affected limb in high sitting position, single limb stance and bipedal stance. However, no difference in the muscle activity was noted in VLO muscle in bipedal stance.
Keywords: trans tibial amputation, patellar tendon bearing supracondylar prosthetis, surface electromyography.
Measuring Technical Efficiency in Venezuela: The Dual-Purpose Cattle System (DPCS)
Authors: Ortega Leonardo , Ward Ronald W. , Andrew Chris 
Published: May 2021

The dual-purpose cattle system (DPCS) describes traditional cattle production practice in the lowland tropics of Latin America where a mix of Zebu, Criollo, and European breeds are used in meat and milk production (Sere and de Vacarro, 1985; Castillo, 1992). The economic importance of DPCS to these regions is clear since Tropical America uses this production system for 78% of its total bovine population and 41% of its milk production (Fernandez-Bacca, 1995; Estrada, 1993). In Venezuela, this system represents approximately 90% of total national milk production and around 60% of total milk consumption (Plasse, 1992).

In Bangladesh, the transformation of dairy farming from livelihood-oriented to enterprise-driven farming system might require deeper understanding on the regional differences in terms of regional potential for further dairy development. This, however, entails detailed data on dairy farm at regional level. Since the data are relatively very scarce in one hand and on the other hand, even available, are contradicting among various sources in terms of data accuracy and precision, the application of the regional modeling on the data and extrapolates to the national data and vice-versa is one of the ways to identify the possible options to improve the data availability and quality. Considering this, the current study was undertaken to assess the data inconsistency by comparing the dairy herd structure and its milk production at regional level and propose a validation tool to arrive at the national data by using the regional findings. The International Farm Comparison Network (IFCN) Regional Modeling Approach (RMA) along with the locally developed Integrated Dairy Research Network (IDRN) farm model was used. The primary data was collected from three divisions (9 districts) from the North-Western part of the country. The results revealed that proportion of household farm dominates over family and business farm while considering the total dairy cow as unit for defining the farm type. The share of the cross bred cows to the local cows is 74.6% and 24.4%, respectively. However, the proportion of lactating cows over dry cows and heifer seems to be higher in local cows (48.8%) than cross breed cows (34.2%). The average milk production for all regions is 4.49 lit/day/cow while that for cross breed is 6.23 lit and local 1.71 lit/day/cow. Using regional model and its coefficient on average milk production, herd composition, proportion of lactating cows on total milk production of DLS and IDRN revealed that IDRN new model estimates 36.5% lower milk than the DLS in 2019 and 33.5% lower in 2018. The IDRN version 1.0 and 2.0 model difference was found to 15.4% and 18.3% lower for 2018 and 2019, respectively. The model setup, calibration and validation are time-demanding and challenging tasks for these large set of data, given the scale intensive data requirements, and the need to ensure the reliability data from multiple regions. This study concludes that regional modeling is quite useful for validating the regional share of the milk production and national milk production. However, this study would recommend for using standardized for data collection, validation and thus conducting further study on the other regions and finally including all regions of the country.

Authors: Itiowe K. , Oghonyon R. , Kurah B. K. 
Published: May 2021

The sediment of #3 Well of the Greater Ughelli Depobelt are represented by sand and shale intercalation. In this study, lithofacies analysis and X-ray diffraction technique were used to characterize the sediments from the well. The lithofacies analysis was based on the physical properties of the sediments encountered from the ditch cuttings. Five lithofacies types of mainly sandstone, clayey sandstone, shaly sandstone, sandy shale and shale and 53 lithofacies zones were identified from 15 ft to 11295 ft. The result of the X-ray diffraction analysis identified that the following clay minerals – kaolinite, illite/muscovite, sepiolite, chlorite, calcite, dolomite; with kaolinite in greater percentage. The non-clay minerals include quartz, pyrite, anatase, gypsum, plagioclase, microcline, jarosite, barite and fluorite; with quartz having the highest percentage. Therefore, due to the high percentage of kaolinite in #3 well, the pore filing kaolinite may have more effect on the reservoir quality than illite/muscovite, chlorite and sepiolite. By considering the physical properties, homogenous and heterogeneous nature of the #3 Well, it would be concluded that #3 Well has some prospect for petroleum and gas exploration.
A Case Study on Disaster Insurance in Kenya
Authors: Mohtasin Fahmid 
Published: May 2021

This study aims to provide a comprehensive outlook on the active disaster insurance scene in the East African country, Kenya. It begins with a geographic and economic analysis of the country followed by its historical challenges with natural disasters, namely droughts. The study is both qualitative and quantitative in nature and mostly deals with secondary sources of data. Establishing the current status of the country, the discussion brings into light the three insurance programs that have gained prominence there in the last decade: Kenyan Livestock Insurance Program (KLIP), Area Yield Index Insurance (AYII), and Kilimo Salama or Safe Agriculture. These programs use state of the art remote sensing technology to determine the availability of pasture, crop yields, etc. through standardized vegetation indices. Once the indices reach a predetermined minimum threshold, they trigger the payout mechanisms of the respective programs, economically uplifting the vulnerable communities involved and avoiding potential disaster. The programs are partially subsidized by the government which allows ease of adoption for local communities and helps stabilize the economy by keeping the agriculture and livestock sectors in balance. The study also acknowledges the limitations faced by the programs in order to provide a more realistic depiction and aims to encourage the piloting of similar programs in other developing nations like Bangladesh.

Published: May 2021

An experiment was conducted to investigate the immune response induced in chickens by capsular extract of Pasteurella multocida isolated from rats wandering in and around the poultry farms. The rat isolate of P. multocida was isolated and identified by cultural, morphological, and biochemical characteristics, followed by capsular extract preparation and experimental vaccine development. The isolated P. multocida was found Gram-negative, non-motile, non-spore forming rod occurring singly or pains and occasionally as chains or filaments in Gram’s-staining method. The isolates consistently produced acid from dextrose, sucrose and mannitol but not fermented maltose or lactose. The Capsular antigen was extracted and confirmed by acriflavine test. Finally, experimental fowl cholera vaccine was prepared. Primary vaccination was performed at the dose rate of 5.6×107 CFU/ml through intramuscular and subcutaneous routes in birds of group A (10 birds) and group B (10 birds) and group C (10 birds) were control birds. Secondary vaccination was similarly performed after 15 days of primary vaccination in groups A and B. The levels of pre-vaccination and post-vaccination sera were determined by passive haemagglutination test. The passive haemagglutination antibody titre was recorded on 15 and 35 days of post vaccination in groups A and B. It was demonstrated that experimental capsular extract fowl cholera vaccine conferred 100% protection (p<0.01) against challenge infection and found to be safe. It could be suggested that after thorough field trial, the experimentally prepared capsular extract FC vaccine using rat isolate of P. multocida may be used side by side with conventional FC vaccine.

Published: May 2021

Poultry industry is the promising sub-sector in livestock, which has been expanding day by day. Among the poultry species, backyard chicken is one of the appropriate incomes generating species in rural areas of Bangladesh. Parasitic infections have been considered as one of the major hindrances for backyard chicken rearing. Therefore, the present study aimed to investigate the prevalence of gastrointestinal helminths of backyard chicken in some selected areas of Bangladesh through their detailed morphological identification. A total number of 108 gastrointestinal tracts were examined for helminths from April 2018 to July 2018. The collected helminths were identified according to the keys and description of Yamaguti (1961) and Soulsby (1982). A high rate of helminth infection (100%) was observed in backyard chickens in Bangladesh. One cestode, Raillietina tetragona (67.59%); two nematodes, Ascaridia galli (43.51%) and Heterakis gallinarum (28.70%); and two trematodes, Catatropis verrucosa (21.29%) and Echinostoma revolutum (6.48%) were encountered during the study. Most of the helminths were recovered from small intestine followed by caecum. All five species of helminths were found from Dhaka and Pabna, but surprisingly no trematodes were found from Bandarban. Out of 108 chickens, 29.62% were infected with single species of helminths while the rest 70.38% harbored mixed infections. This work strongly suggests that helminths create serious problems in backyard chicken as they hamper production and therefore, appropriate control strategies are needed to design for better production.

An experiment on induced breeding of gang magur, Hemibagrus menoda (Hamilton, 1822) using Ovatide hormone was carried out at in the Field Laboratory Complex of Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh. This study consists of three treatments each with three replications. The objective of the experiment was to find out the effective dose of Ovatide hormone for induced breeding. A total number of 54 brood fish were used for the experiment among which 36 were male and 18 were female. Brood fish were kept in the ratio of 2♂:1♀ for breeding purpose. Female brood fish were injected at the rate of 7, 5, 3 ml Ovatide/kg body weight while the males were injected with 3, 2.5 and 1.5 ml Ovatide/kg body weight respectively in T1, T2, and T3 at the same time. The brood fish were injected with single dose of Ovatide in all treatments. Ovulation rates were 0%, 100%, 63%; fertilization rates were 0%, 97%, and 90%, and hatching rates were 0%, 95% and 76% in treatments T1, T2, and T3 respectively. Fertilized eggs were incubated for 21-22 h in all the treatments. Higher ovulation rate (100 %), fertilization rate (97%), hatching rate (95%) and survival rate (85%) were found in treatment T2. Therefore, the optimum dose of Ovatide hormone for induced breeding of H. menoda is 2.5 and 5 ml Ovatide/kg body weight of male and female brood fish, respectively.
