Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood. While some 5 to 8% of ALL cases will have neurological involvement at initial presentation, up to 30% of relapses have neurological manifestations. We present the case of a pediatric ALL with meningo-radiculoneuropathy revealing a relapse while on maintenance therapy. Our patient presented the Philadelphia mutation, that is the t(9;22), and thus was at high risk of neurological involvement. The diagnosis of relapse was based on neuroimaging and CSF study. Treatment entailed modified Hyper CVAD chemotherapy with repeated intrathecal treatment until CSF clearance. Outcome was favorable with gradual regression of neurological symptoms.

Authors:   Department of Obstetrics and Gynecology, Weill Bugando School of Medicine, Catholic University of Health and Allied sciences, P.O. Box 1464, Mwanza, Tanzania., Chibwe Elieza
Published: November 2022

Asherman's syndrome is a syndrome that follows postpartum or postarbortal curettage, it might present with menstrual abnormalities such as oligomenorrhea, amenorrhea, hematometra, recurrent abortions and infertility being the commonest presentation. This pathology arises as a result of partial or complete adherence of the anterior and posterior wall of the uterus due to disruption of the basalis layer of the endometrium which can occur following postarbortal curettage, caesarian section, multiparity or myomectomy. The diagnosis of Asherman’s syndrome can be reached using Hysterosalpingography and transvaginal hydroultrasonography, but they have a high false-positive rate because many polyps and minor fibroids can be misdiagnosed as adhesions, for accurate diagnosis it is important to use hysteroscopy which is termed as a gold standard. Therapy includes adhesiolysis hysteroscopic then the intrauterine device of copper T and estrogen to stimulate endometrial proliferation and reepithelization.

Orthodontics is based on the concept of ideal occlusion, so it is essential to have a notion, as complete as possible, of normal or ideal occlusion so that it is possible to correctly diagnose malocclusions. In normal occlusion defined by Angle, there is a molar relationship so that the mesiobuccal cusp of the maxillary first molar occludes in the buccal groove of the mandibular first molar and, in which the teeth are positioned in a slightly curved line of occlusion. This line of occlusion is divided into upper and lower [1].

Published: November 2022

Rotating panel used in the Labour Force Survey (LFS) causes correlation possibility of estimations of labor markets errors. Knowledge of autocorrelation is important in the context of the trend estimation of labor market parameters. Dismissal of autocorrelation can result in the trend curve it will be fraught with volatility, characteristic of auto-regression processes. Estimation errors are not observable, thus it is not possible to estimate the autocorrelation coefficients by conventional estimators. This paper describes the adaptation of methods for estimating the errors of autocorrelation coefficients (proposed by Pfeffermanna et al.), The rotational scheme in LFS. Then, this method was used to estimate the autocorrelation coefficients in error estimation of the unemployment rate in the province. Greater Poland for six domains defined by gender and age.

The objective of this study was to determine the effect of nickel (Ni) on growth performance, nutrient utilization, urease activity, and endocrine variables in growing cattle. Growing Hariana heifers (18) were randomly assigned into three groups (n=6), i.e. groups either without Ni supplementation (Ni0.0; control) or supplemented with 1.5 mg of Ni/kg DM (Ni1.5), and 3.0 mg of Ni/kg DM (Ni3.0). The experiment lasted for 90 days. Heifers supplemented with Ni showed higher nutrient intake and average daily gain (ADG) than control group. The nutrient digestibility was not affected by treatment, while the Ni supplemented animals showed higher intake, excretion, and nitrogen balance. The urease activity was comparable and higher in the Ni1.5 and Ni3.0 groups than in the control group. There was no effect of treatment on the metabolism of calcium (Ca), phosphorus (P), zinc (Zn), copper (Cu), and chromium (Cr). However, iron (Fe) retention showed a negative association with Ni levels. Plasma cortisol concentration was lower while the insulin like growth factor-1 (IGF-1) and tetraiodothyronine (T4) were higher in the Ni3.0 group compared to the Ni0.0 group, with Ni1.5 being intermediate. The plasma concentrations of triiodothyronine (T3) and thyroid stimulating hormone (TSH) were not affected by dietary treatment. Plasma Ni concentration showed a dose dependent increase whereas, plasma levels of other minerals were not affected by treatment. In conclusion, dietary Ni supplementation in growing Hariana heifers improves performance and nutrient utilization by modulating urease activity and endocrine growth biomarkers.

Published: November 2022

In this study, prevalence of the gastrointestinal (GI) parasites in pigs from India was estimated by employing scientometrics. The prevalence studies on the GI parasites of pigs (n=21) were acquired from online and offline databases (timeline: 2010-2021) and meta-analysis was performed using meta package in R-software. The prevalence of GI parasites in pigs was 54% (95% level: CI 39-69%, PI 5-96% of 8,921 samples tested) in India. A higherprevalence of 81% was reported in 2010 than the recent years (2016-21). The highest prevalence in South zone (78%), and least in West zone (35%) was observed. The prevalence of GI parasites was highest in Tamil Nadu (96%) and lowest in Maharashtra (28%). The higher prevalence was observed in protozoa (30%) than other parasite classes and lower in cestodes (4%) in pigs. More number of studies have been reported on nematode parasites indicating its importance in pigs. A higher prevalence was observed in the studies conducted on samples (84%) collected from slaughterhouse than the faecal samples (46%) in pigs. Among the parasite species, coccidia (29%) were most commonly reported whereas Globocephalus urosubulatus (0.7%) was observed sporadically low. Amongst nematodes and trematodes, a higher prevalence in Ascaris spp. (27%) and Amphistomes (12%), correspondingly was observed. The high GI parasites prevalence zones, states, parasite classes, sample types and parasite species recognized will assist the stakeholders and decision makers, in control and preventive approaches. Further, this study provides the baseline information on GI parasites prevalence in pigs of India for devising effective deworming strategies which ultimately lead to beneficial piggery in India.

Published: November 2022

A three-year study was carried out at six locations in three agro-ecologies representing the areas of irrigation water availability at critical stages during kharif maize (Zea mays L.) in North Western Plain Zone (NWPZ), North Eastern Plain Zone (NEPZ) and Peninsular Zone (PZ) for optimizing the nutrient requirement and realizing potential yield of the popular genotypes. The study included five popular genotypes/hybrids with three nutrient management practices of RDF, 50% RDF/Farmer Fertilizer Practices (FFP) and nutrient expert based site-specific nutrient management (NE-SSNM) in the split-plot design and replicated thrice. The grain yield of maize was significantly higher at four locations with NE-SSNM however; it was at par with RDF at two locations. The gross returns followed the same trend as of grain yield but the returns over fertilizer cost (ROFC) were significantly higher with NE-SSNM which indicates that the use of these nutrient management practices has the potential to rationalize the nutrient management practices in maize. Hence, it was concluded that the NE-SSNM could be an effective strategy for realizing the potential yield and enhancing net returns of maize production in NWPZ, NEPZ and PZ.

Authors: Ghosh Sourav , Singh K N , Thangasamy A , Datta Debarati , Lama Achal
Published: November 2022

In the present investigation an attempt has been made to forecast and understand the volatility transmission in onion prices for three vital markets in Maharashtra, viz. Lasalgaon, Pune and Nagpur. The ARIMAX-GARCH model was employed to estimate mean and volatility among the different markets and also examined the nature of dynamic correlation using the DCC model. The quantity arrival of each market was considered as covariate to improve the mean forecast. We have obtained superior results for ARIMAX-GARCH over ARIMAX model in terms of forecasting. Forecasting efficiency of the models was judged in terms of lower RMSE and MAPE values. Presence of volatility was found in and between the markets as well. Lasalgaon market exhibits highest volatility, whereas the combination of Lasalgaon and Nagpur market experiences the largest volatility movement among them. Identification of interdependency of the markets in terms of volatility movement helps the traders as well as policy makers in a large way. The concerned stakeholders can easily anticipate the prices of other dependent market based on the behaviour of one market.
Lærerstudenter i elevrollen møter utforskende arbeidsmåter i naturfag
Authors: Haslekås Camilla , Kittilsen Silje
Published: November 2022

Utforskende arbeidsmåter har fått et økt fokus i skolen. Bruk av utforskende arbeidsmåter kan bidra til økt engasjement og interesse hos elevene, samt dybdelæring. Likevel viser det seg at begrepet utforskende arbeidsmåter blir brukt og tolket på mange ulike måter, og mange lærere finner det vanskelig å ta disse i bruk i undervisningen. Det er derfor viktig at kommende lærere får erfaringer med og innsikt i disse undervisningsformene. I denne studien har vi undersøkt åtte lærerstudenters refleksjoner rundt utforskende arbeidsmåter etter selv å ha vært i elevrollen i et utforskende undervisningsopplegg i naturfag laget for 5.-7.trinn. Resultatene viser at lærerutdanners modellering etterfulgt av tilrettelagt refleksjon gir studentene en begynnende forståelse for sentrale aspekter ved utforskende arbeidsmåter. Slik som for eksempel at det er sentralt å formulere spørsmål, og at elvene deltar aktivt i å søke etter og finne svar på disse. Lærerstudentene fant undervisningsopplegget lærerikt og engasjerende, og uttrykker at de selv vil ta i bruk undervisningsformene som lærere. Dette til tross for at de også så noen utfordringer ved disse arbeidsmåtene. Vi argumenterer for at førstehåndserfaring med utforskende arbeidsmåter gjennom elevrollen, samt diskusjon og refleksjon i et læringsfellesskap, har påvirket studentenes læreroppfatninger om utforskende arbeidsmåter. Læreroppfatninger er en av de viktigste faktorene for at lærere skal ta i bruk nye undervisningsstrategier.

More than 17 million people have been affected and USD144 billion lost through major wildfire events over the last 30 years. In addition, the degradation of air quality due to the creation of aerosols and ozone from fires resulted in between 260 000 and 600 000 premature deaths each year. The risk that wildfires pose to people and the environment is increasing due to climate change. By the end of the century, the frequency of wildfires, compared to a 2000-2010 reference period, is predicted to increase by a factor of 1.31 to 1.57 with the number of extreme wildfires increasing even further. Pyrocumulonimbus or pyroCbs are storm clouds produced by particularly large and intense wildfires that can produce storm clouds. These storm clouds create their own weather fronts which can make wildfire behaviour unpredictable through strong winds and ignite new fires through lightning. PyroCbs also convect wildfire aerosols into the stratosphere, where they remain for several months. These events, which can be on the scale of a volcanic eruption, have important impacts on the Earth's climate. PyroCbs could also hinder the recovery of the ozone layer.

Early Warning Systems and Response Mechanisms for Countering Violent Extremism in Tanzania
Authors: Walwa William John
Published: November 2022

This paper analyzed the early warning and response mechanisms developed and deployed at the local levels to respond to episodes and threats related to violent extremism. Qualitative methods – namely key informant interviews and documentary review were employed to gather findings from local community members and leaders, government official and police in Mwanza and Mtwara regions. The paper discovered that, first, growing incidents of violence in Tanzania ensued from the weakening of early warning and response mechanisms, and secondly, recent interventions to reinforce and deploy early warning and response mechanisms have helped to increase the capacity of communities to prevent incidents of violence. However, the paper found that, that even though the usefulness of early warning and response mechanisms to prevent VE - related security threats is acknowledged by all actors, success in the operationalization of these mechanisms is politically negotiated. Findings point to the need to invest in early warning mechanisms allowing communities to engage in developing context – specific solutions to address growing cases of violence.
RESEARCH NOTE: Tour Guides’ Perception for Sustainable Tourism
Authors: Philemon, John R , Jani Dev
Published: November 2022

The aim of this study was to evaluate tour guides’ perception of tourism sustainability using triple bottom line dimensions of economic, environmental, and socio-cultural aspects as informed by Social Exchange Theory. A structured questionnaire was self-administered to tour guides around Mikumi National Park in Tanzania. Descriptive and mean comparison tests were performed with results indicating that tour guides perceive tourism to have positive economic and environmental impacts. However, surveyed tour guides thought that tourism in the area stimulated prevalence of bad behaviours like prostitution, alcoholism, and gambling. Furthermore, the results indicate that tour guides perceive tourism to increase imbalance and inequality in economic benefits. The results complement previous studies by capturing tour guides’ views as well as testing the Social Exchange Theory. Furthermore, the results offer insights to destination managers and policy makers on possible interventions in furthering holistic and sustainable destination management.

People's Livelihoods and Conservation: Community-based Conservation in Maswa Game Reserve
Authors: Kuboja James Benedict , Chuhila Maxmillian Julius
Published: November 2022

After a long time of operation of the fortress conservation method in Wildlife Management Areas (WMAs) and Game Reserves, experts have debated whether Community Based Conservation (CBC) is a reality or just another fantasy. Because of the way they are governed in relation to their use values, WMAs and Game Reserves provide varied conservation experiences. According to this study, CBCs are never universally beneficial or unsuccessful, but rather rely on the context in which they are used. Despite the hurdles that this strategy faces in different areas, Maswa Game Reserve (MGR) has shown some success. This paper investigates the dynamics of CBC in Maswa Game Reserve using a historical perspective. It makes use of previously unseen historical records to highlight the dynamics of conservation politics in connection to local people's livelihood. We found that CBC was largely ineffective in MGR between the 1980s and the early 1990s, until it was seriously adopted in the mid-1990s and early 2010s, when it significantly enhanced people's participation in conservation efforts. Increased public participation in MGR reduced the depletion of wildlife resources, but this did not imply the exercise was without resentments. As a result, CBC is not a comprehensive refutation of fortress conservation's flaws, but rather another method of indicating that resource access, management, and use is a negotiated process defined by who receives what.
Research on English Literacy Among Chinese College Students

Published: November 2022

English is learned as a foreign language among Chinese college students. Traditionally, tests and examinations are two major approaches used to assess the achievements of English learning among students in China. Despite that the assessment based on these two approaches is effective on screening and selection, its role in monitoring education process and improving education quality is disregarded. The overall development of students’ English literacy, which includes their awareness to the differences between English and Chinese languages, their attitudes to English learning, their knowledge on English language and their competence to utilize English in authentic contexts, cannot be assessed via these two approaches. Therefore, it is of great necessity to construct a new framework of assessment covering these aspects. In this research, on the basis of the theory of educational assessment (the fourth generation) and the concept of teachers’ assessment literacy, such a framework is proposed and used to assess the level of English literacy among Chinese college students. This research intends to explore the level of English literacy among Chinese college students and the influential factors to their English literacy. This research will provide a theoretical significance as well as the practical significance to the development of assessment on English education in China.

Published: November 2022

New variants of canned skipjack tuna have been developed by large manufacturers of canned tuna in the Philippines. This study analyzes the expenditure and price elasticities of canned tuna and determines the implications for sustainable fishery. An AIDS (almost ideal demand system) model incorporating an income group variable was used to estimate these elasticities. This study utilized a pooled time series data of 459 weekly point-of-sale observations from 2010–2012 of three store branches of a large supermarket chain in southern Philippines. The point-of-sale data suggest that canned tuna consumption is composed mostly of tuna in sauce with vegetables followed by tuna in oil and tuna in sauce without vegetables. For both high- and low-income groups, the expenditure elasticities have the expected positive signs – indicating that as the income of consumers’ increases, the quantity demanded for canned tuna in three product mediums also increases. For high-income consumers, consumption of tuna in sauce with and without vegetables is more responsive to income changes. The own-price elasticities of the three product mediums across high- and low-income store branches have negative signs – suggesting that as their own price increases, the quantity demanded for these products decreases. The cross-price elasticities suggest that tuna in sauce with vegetables is a substitute for tuna in oil and in sauce without vegetables for both income groups. Thus, promoting more use of vegetables through product development may lead to a lower volume of tuna meat used in canned tuna products, which contributes to addressing tuna resource sustainability

Constituting one of the most commonly used antihypertensive drug families are the angiotensin receptor blockers (ARBs). The aim of this study was to identify the variants associated with response to ARBs that may potentially be used as markers for designing a tailor-fit treatment strategy for hypertension. An unmatched case-control study was done among adult hypertensive Filipino patients maintained on ARBs. Genotypic analysis of blood DNA was conducted. Logistic regression analyses were performed to determine association of clinical and genetic variables with ARB response. A total of 69 poor responders and 126 normal responders were included in the study. After performing univariate logistic regression, five single nucleotide polymorphisms showed association with poor response to ARBs. The genetic variant rs6596140 remained significant (dominant model; OR 2.36, p = 0.009) after adjusting for female sex and age. Variant rs6596140 was found to be associated with poor response to ARBs among Filipinos. Prior to clinical application, verification is recommended prior to clinical application. As the function of this variant is presently unknown, an investigation to elucidate its role in ARB response in hypertension is also recommended.
Effect of Modified Cassava Starch in Reduced-fat Mayonnaise by Correlating Emulsion Stability with Anti-oxidation Reaction Using Gas Chromatography–Mass Spectrometry (GC-MS)
Authors: Parreño Ronaldo , Carandang Maricar
Published: November 2022

Modified starches are essential firming additives in many food processes as they act as emulsion stabilizers. Presently, they are produced mostly from corn and potatoes, but cassava is a good alternative source to augment the rising global demand for starch. In this work, cassava starch from a native variety called Manihot esculenta Crantz, modified by facile heat-moisture treatment (HMT) method was used in reduced-fat mayonnaise to retain product consistency and texture but, more importantly, to contribute to the stabilizing effect of emulsions. Varying amounts of modified cassava starch in mayonnaise formulation were evaluated to correlate emulsion stability with a reduction in the amount of oil and the presence of anti-oxidation compounds that slow down chemical processes. The anti-oxidation process resulting from starch composition in the emulsion was measured by an analytical method using the combined gas chromatography and mass spectrometry (GC-MS). 22 complete factorial experiments were conducted in determining the significant effects and interactions between the amount of modified starch and oil. Correlations of these two factors with resulting stability as response variables were analyzed. Two-way ANOVA showed significant relationships in emulsion stability as directly proportional to the amount of oil in the emulsion as well as the modified starch. The results confirmed that individual factors both influenced the slowing down of emulsion breakdown of mayonnaise. However, it also revealed that modified starch had a greater influence on the concentration of acetic acid as an antioxidant than the effect of oil on the emulsion stability. Thus, this study confirmed that increasing the amount of modified cassava starch correlates to a significant occurrence of anti-oxidation reaction in reduced-fat mayonnaise. The combination of 0.60 wt% modified starch with 50 wt % oil achieved a higher stabilizing effect on emulsions as compared to other combinations. The results proved that predictive analysis of the capacity to prevent the auto-oxidation process is one way of predicting the long-term stability of the mayonnaise after 24 h.

Authors: Ramos Nerissa , Lamorena Rheo
Published: November 2022

This study validated a new method that is not only rapid and cost-effective but also accurate and reliable in the detection of trace metals in rice. The microwave plasma atomic emission spectroscopy (MP-AES) method of tracing elements in rice was validated to quantitatively measure the copper (Cu), manganese (Mn), zinc (Zn), cadmium (Cd), and lead (Pb). Validation that involved precision, accuracy, linearity and dynamic working range, standard addition for matrix effects, limit of detection (LOD), and limit of quantitation (LOQ) showed that the MPAES method was comparable with flame atomic absorption spectroscopy (FAAS) data. The agreement between experimental values from MP-AES and the reference values of CRM 804 gave a very good means of the accuracy of the MP-AES method. The LOQ values achieved were low enough and suitable for detecting trace metals at low levels found in the samples. Thus, the proposed MP-AES method in this work is found to be precise, accurate, sensitive, and reliable. The validated method was applied successfully to rice samples collected from different areas. The MP-AES measurement results showed that trace metals such as Cu, Mn, and Zn were present in 20 rice samples collected from selected provinces of Central Luzon. Therefore, the MP-AES method can be a practical alternative technique to the established method.

Published: November 2022

Banana (Musa sp.) leaf is widely used as a food contact material (FCM) in the Philippine foodservice industry. In spite of its usage in serving and wrapping various raw and cooked foods, the Association of Southeast Asian Nations (ASEAN) general guidelines on FCMs exempted its application to banana leaf (BL) and other natural materials that have not undergone chemical modification. This study documented the knowledge and practices in the utilization of BL in foodservice establishments within the top five local government units (LGUs) in Metropolitan Manila, Philippines. Key informant interviews using a semi-structured questionnaire and participant observation were employed in data collection. Data were analyzed using the constant comparison method. Results showed that despite technological and scientific advancement, the BL has remained a functional FCM in the foodservice industry due to its perceived ethnic, sensory, and environmental impacts. The BL specifications – including leaf maturity, dimensions, integrity, cleanliness, and varietal source – are related to its functionalities as FCM. Generally, preparation methods employed by foodservice establishments include wiping, washing, and heating. These methods of preparation were found to be significantly associated with types of food products. The efficacy of these preparation methods needs to be evaluated due to possible leaf contamination and deterioration due to improper handling and storage prior to usage. Furthermore, the foodservice industry identified BL supply, price, and quality issues that should be properly addressed. As an FCM, BL influences final food product quality and safety. Thus, the utilization of BL by other actors within the foodservice supply chain should be further studied to provide baseline information for the establishment of Philippine standards for BL as an FCM.
