NMR Analyses of Carbohydrate–Water and Water–Water Interactions in Water/DMSO Mixed Solvents, Highlighting Various Hydration Behaviors of Monosaccharides Glucose, Galactose and Mannose
Authors: Tatsuoka Hiroaki , Yamaguchi Takumi 
Published: January 2023

Abstract
Interaction with water molecules is a potential factor for regulating carbohydrate functions. We analyzed the influences of methyl α-glucoside, methyl α-galactoside and methyl α-mannoside on water in solution through NMR measurements. In order to compare the hydration behaviors according to the geometric characteristics of monosaccharides, proton exchanges between the carbohydrate and water and between water molecules were observed using H2O/D2O and dimethylsulfoxide mixed solvents to employ deuterium-induced isotope shifts. 13C NMR analyses focused on the carbohydrate hydroxy groups revealed that the carbohydrate–water proton exchange in the mannoside solution proceeded slower than in others. Meanwhile, the frequent proton exchange between waters in the mannoside solution was shown by NMR observations of water signals. Our NMR experimental results shed light on the variation of solvation environments of carbohydrates according to their geometric characteristics. Mannose presumably allows for unique orientations of the adjacent water molecules to induce the expansion of water networks efficiently.

Robust Assortment Optimization Under the Markov Chain Choice Model Assortment optimization arises widely in many practical applications. In this problem, the goal is to select products to offer customers in order to maximize the expected revenue. We study a robust assortment-optimization problem under the Markov chain choice model, in which the parameters of the choice model are assumed to be uncertain, and the goal is to maximize the worst case expected revenue over all parameter values in an uncertainty set. Our main contribution is to prove a min-max duality result when the uncertainty set is row-wise. The result is surprising as the objective function does not satisfy the properties usually needed for known min-max results. Inspired by the duality result, we develop an efficient iterative algorithm for computing the optimal robust assortment under the Markov chain choice model. Moreover, our results yield operational insights into the effect of changing the uncertainty set on the optimal robust assortment.

Abstract. Khuluq AD, Widaryanto E, Ariffin, Nihayati E. 2022. Adaptive strategy of Stevia rebaudiana to environmental change in tropical climate based on anatomy and physiology characteristics. Biodiversitas 23: 5710-5717. High solar radiation and air temperature are the main influencing factors for plant growth and development in tropical climates. This study's objective was to understand stevia adaptation to microclimate changes at several altitudes in tropical climates. The study was conducted in a completely randomized design with altitude differences consisting of highlands, medium lands, and lowlands with ten replicates. The results showed that stevia was exposed to temperatures above 20oC during growth in the highlands by 36.46%, and in the medium lands to lowlands by 92.85%-93.96%. Meanwhile, the temperature above 30oC in the lowlands is 17.98% highest of the others. Stevia adapts to a high temperatures by increasing stomatal density, trichomes, and photosynthesis rate. Moreover, decreasing stomata (width, aperture, open percentage), leaf thickness, palisade length, xylem diameter, conductance, and transpiration rate. Stevia in the medium lands shows good adaptability with a high photosynthesis rate, percentage of open stomata 93.15%, leaf thickness 382.56 µm, and xylem diameter 30.97 µm, which is no different from the highlands. Thus, the medium lands have the potential as a new area of stevia development in a tropical climate, considering the increasingly competitive use of agricultural land in the highlands.

Abstract. Athifa IR, Sari APZNL, Maharani D, Budisatria IGS, Bintara S, Noor YG, Hidayat R, Panjono. 2022. The pre-weaning growth of lambs from crossbreeding between Garut ewes with Dorper rams. Biodiversitas 23: 5738-5743. This study was aimed at determining the productivity of lamb from mating between Garut ewes and Dorper rams. The animals used were 108 sheep. A total of 98 heads of Garut ewes were randomly divided into two groups; the first group was mated with Dorper rams (5 heads), while the second group was mated with Garut rams (5 heads) as a control group. The data observed were birth weight, weaning weight, average daily gain (ADG), reproduction index (RI), and productivity index (PI). The data were analyzed with an independent sample T-Test. Birth weight, weaning weight, and ADG of Garut and Dorper crossbred lambs were 2.20±0.54 and 2.60±0.71 kg; 14.91±3.57 and 16.27±3.69 kg; and 90.21±32.11 and 119.12±42.64 g/day, respectively. Pre-weaning growth of Dorper-crossed lambs was higher (P<0.05) than those of Garut lambs. The RI and PI of Garut ewes mated with Garut and Dorper rams were 3.15±1.38 and 2.87±1.33 head/year; and 32, 10±15.53 and 38.91±21.00 kg/year, respectively. The PI of ewes mated with Dorper rams was higher (P<0.05) than that of Garut ewes mated with Garut rams. It is concluded that the cross of the Garut ewes with the Dorper rams improved productivity by increasing the pre-weaning growth of the lambs.

Urine biochemical profile analysis and transabdominal ultrasonography for pregnancy detection in the endangered lowland anoa (Bubalus depressicornis). Biodiversitas 23: 6056-6061. The population of lowland anoas (Bubalus depressicornis) has decreased significantly due to illegal hunting and habitat loss. As such, the urgency in developing successful ex-situ conservation programs cannot be overstated. Ex-situ breeding programs of anoas, however, are hindered by difficulties in early pregnancy detection. The failure to detect pregnancy at an early stage often results in miscarriage due to repeated breeding attempts of unconfirmed pregnant females. Moreover, frequent false heat during 5 to 6 months of pregnancy corroborated the repeated breeding of pregnant females. Therefore, early detection techniques are needed to improve breeding success. The present study evaluated the use of urine biochemical profiles as a minimally invasive approach for early pregnancy detection and transabdominal ultrasonography as a confirmation tool of false heat in four lowland anoas. Statistical analysis showed that glucose and protein level were significantly elevated during pregnancy since the 0 days of post-mating (p<0.05) and consistently higher compared to the non-pregnant period. Meanwhile, transabdominal ultrasonography successfully identified organ structures and development by the 155th, 176th, 180th, and 191st days of pregnancy. The present study suggests that urine biochemical data provide a promising, minimally invasive approach to early pregnancy detection in anoas. Incorporating urine data and ultrasonography can significantly help to maintain pregnancy by validating false heat.

Abstract. Kadir NN, Husain AAA, Irmawati, Priosambodo D, Jamal M, Ilyas M, Malkab ANI, Fasirah E, Moore AM. 2022. Short Communication: Rare grouper Epinephelus miliaris from market surveys in South Sulawesi, Indonesia. Biodiversitas 23: 6070-6074. Groupers of the genusEpinephelus are tropical demersal fishes of both ecological and economic importance. However, knowledge is still limited regarding the diversity of fish caught and traded as well as the fine-scale distribution of many species. During a series of market surveys to photograph and identify groupers exploited in South Sulawesi, Indonesia, a small number of specimens of a widespread but rare grouper, Epinephelus miliaris, were found. The purpose of this study was to contribute to the body of knowledge on E. miliaris by analyzing and presenting spatial, morphological, and meristic data collected on these specimens and discussing the findings with respect to the current state of knowledge regarding this species. Our findings add Sulawesi, including the Makassar Strait and Gulf of Bone, to the recorded distribution of E. miliaris, to the south of the range according to the International Union for Conservation of Nature (IUCN) Red List. Both specimens were within the juvenile or sub-adult size range for this species. We conclude that there is a need to re-evaluate the range of this species, specifically within Indonesia, in fisheries and fish biodiversity databases.

Abstract. Irsyadi MB, Sawitri WD, Purwantoro A. 2022. Molecular and phenotypic characteristics of T1 transgenic yellow cosmos (Cosmos sulphureus) carrying neomycin phosphotransferase II gene. Biodiversitas 23: 6097-6105. Yellow cosmos (Cosmos sulphureus) is a tropical ornamental flower that contains secondary metabolites useful fornatural pesticide application. Plant genetic transformation is one genetic engineering method used to increase secondary metabolite accumulation. However, published reports on this issue have yet to be made available. This is the first report of genetic transformation in transgenic yellow cosmos using neomycin phosphotransferase II (nptII) encoding gene. This study aimed to determine the efficiency transformation and phenotypic character of the T1 yellow cosmos transgenic nptII. This genetic transformation was carried out by the floral dip method mediated with Agrobacterium tumefaciens and characterized based on quantitative and qualitative observations, as well as a cluster analysis of transgenic plants. The T1 transgenic yellow cosmos was confirmed using PCR with a transformation efficiency of 73.33% based on the total plants resistant to Kanamycin and 10.57% based on the total seeds transformed. The presence of the nptII encoding gene was shown in transgenic plant samples with a size of 550 bp. In general, the introduction of the nptII gene generated no novel traits except the resistance to the kanamycin antibiotic. However, there was a decrease and increase in the number of stomata and the size of stomata in transgenic plants, respectively. In addition, there was a change in the type of ray floret to a mixture of ligulate and tubular, indicating that the nptII gene affected the phenotype of yellow cosmos. The result revealed that the nptII gene was inserted fairly randomly into the plant genome.

Abstract. Retnaningdyah C, Febriansyah SC, Hakim L. 2022. Evaluation of the quality of mangrove ecosystems using macrozoobenthos as bioindicators in the Southern Coast of East Java, Indonesia. Biodiversitas 23: 6480-6491. The mangrove ecosystem in East Java has been degraded due to land use change. Some of these mangrove ecosystems have been restored. However, the success of these restoration activities has never been evaluated. This study aimed to evaluate the quality of some mangrove ecosystems on the Southern Coast of East Java by observing the physical and chemical quality of water and macrozoobenthos that live in mangroves, especially crustaceans and gastropods, as bioindicators. Samplings were carried out on seven mangrove ecosystems, namely restored ecosystems (Cengkrong, Sine, Getem, Kondang Merak, Clungup Mangrove Conservation/CMC) and natural ecosystems as reference sites (Alas Purwo National Park/TNAP and Sempu island). The water quality parameters observed were pH, conductivity, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD), nitrate, orthophosphate, Total Suspended Solid (TSS), salinity, sulfide content (H2S), oil and fat content, and dissolved lead (Pb) content. The macrozoobenthos communities observed were gastropods and crabs, while the mangrove communities monitored were only trees, using plots, each measuring 10x10 m. The results showed that some water quality parameters did not meet the sea water quality standards for marine life, namely DO and nitrate levels for all locations, H2S, and oil/fat in some locations. The quality of the restored mangrove ecosystem in the Cengkrong and CMC areas was better than that of other sites, with a Shannon-Wiener species diversity index (H') for mangrove trees of 2.796 and 2.235 and was close to the quality at the reference sites, namely Alas Purwo and Sempu island (H' 2.953 and 2.356). The H' value of macrozoobenthos in the Cengkrong and CMC mangrove ecosystem was also high (4.37 and 3.47) and almost the same as the H' value of Sempu Island and Alas Purwo (3.45 and 3.88), while in other mangrove ecosystems it ranged from 1.33 to 2.60. The species diversity of mangrove vegetation had a significant (? 0.05-0.1) to very significant (? <0.05) positive correlation with the diversity of crabs and gastropods, so the diversity of macrozoobenthos (crabs and gastropods) can be used as a bioindicator of the quality of the mangrove ecosystem.

Abstract. Mohammed NMI, Said AGE. 2018. Date palm (Phoenix dactylifera) seeds germination. Cell Biol Dev 2: 63-68. This study aimed to examine if pre-germination treatments could effectively promote date palm (Phoenix dactylifera L.) seed germination in the Nursery of the Horticultural Sector, Ministry of Agriculture and Irrigation, Khartoum, Sudan. Seeds were soaked in water for 0, 2, 4, 6, 8, 10, and 12 days before being planted in one of the following media: sand:clay (1:1), sand:clay (1:2), sand:clay (1:0), sand:clay (0:1), and sand:clay (2:1). The factorial completely randomized block design was employed in this investigation. The 6-day soaking time resulted in the highest percentage of seeds germinating; as the soaking time increased, the percentage of seeds germinating decreased. The 6-day soaking time also improved seed germination, allowing for a 50 % final germination percentage in the shortest time. Sowing seeds in a 2:1 soil mix decreased germination days, resulting in a substantial increase in germination percentage compared to other soil type mixes evaluated, regardless of soaking duration. In addition, seeds soaked for 6 days and planted in a 2:1 soil mix produced the tallest seedlings.

Published: January 2023

Background
Uterine rupture is defined as tearing of the uterine wall during pregnancy or delivery. It can occur during pregnancy or labor and delivery. Rupture of the uterus is a catastrophic event resulting in the death of the baby, and severe maternal morbidity and mortality Despite different interventions done by stakeholders, it remained one of the leading public problems in developing countries like Ethiopia.

Objective
This study assessed the prevalence and determinants of uterine rupture among mothers who gave birth at Hawassa University comprehensive specialized hospital from July 2015 to June 2020G.C.

Method
A case-control study was conducted by reviewing data from a total of 582 patient charts which include 194 cases and 388 controls with a case-to-control ratio of 1:2. Then the data was extracted using a pre-tested and structured data extraction sheet. Data were entered using Epi data 3.1 and exported to SPSS and analyzed using SPSS 20. The association between independent variables and uterine rupture was estimated using an odds ratio with 95% confidence intervals. The statistical significance of the association was declared at P-value < 0.05.

Result
There were a total of 22,586 deliveries and 247 confirmed cases of uterine rupture which makes the prevalence 1.09%. Lack of ANC (Ante-natal care) (AOR = 7.5; 95% CI: 1.9–30.3) inadequate ANC (AOR = 2.45; 95% CI: 1.1–5.57), gravidity ≥5 (AOR = 3.3; 95% CI: 1.36–8.12), obstructed labor (AOR = 38.3; 95% CI: 17.8–82.4) and fetal macrosomia (AOR = 8; 95% CI: 17.8–82.4) are variables which increase the odds of developing uterine rupture. Mothers without additional medical or obstetric conditions are more likely (AOR = 4.2; 95% CI: 2.1–8.65) to develop uterine rupture than mothers with additional medical or obstetric conditions.

Conclusion
The prevalence of uterine rupture is high in the study area. The study also revealed that a decrease in ANC follow-up, gravidity of ≥5, obstructed labor, and fetal weight of >4kg are significantly associated with uterine rupture. Improving the quality of ANC follow-up, intrapartum follow-up and proper estimation of fetal weight are recommended interventions from the study.

Background
Adverse obstetric outcomes have been commonly associated with early childbearing in many low-and middle-income countries. Despite this evidence, scholarly information on early childbearing in the sub-Saharan African region, especially Nigeria, is limited. This study examines the predictors of young maternal age at first birth among women of reproductive age in Nigeria using multi-level analysis.

Methods
Data from the most recent Nigeria Demographic and Health Survey conducted in 2018 were analyzed. A total of 29,949 women of reproductive age (15–49 years) were considered for the study. Descriptive statistics using weighted percentage and chi-square test of independence (χ2) were first used to describe the variables of interest. This procedure was followed by a multilevel analysis of factors associated with young maternal age at first birth in Nigeria at p<0.05 level of significance.

Results
Approximately 36.80% of the sample population had their first birth before the age of 18. Mothers residing in the North-East region [aOR = 1.26; 95% (CI = 1.13–1.42)] and practicing Islam [aOR = 1.17; 95% (CI = 1.05–1.29] were more likely to have their first birth before the age of 18 than those in the North-Central region and those practicing Christianity. Living in communities with medium literacy level [aOR = 0.90; 95% (CI = 0.82–0.99)] and high literacy level [aOR = 0.71; 95% (CI = 0.62–0.81)], being within richest wealth index [aOR = 0.61; 95% (CI = 0.53–0.71)] and being Yoruba [aOR = 0.46; 95% (CI = 0.39–0.56)] were associated with lower odds of young maternal age at first birth.

Conclusion
More than one-third of women of reproductive age in Nigeria had given birth to their first child before 18 years. Thus, there is a need for the Nigerian government and other stakeholders, including Non-Governmental Organisations and Civil Society Organisations to formulate and implement policy interventions targeted at reducing early childbearing among women of reproductive age in Nigeria.
