Structural diversity and conservation implications of Parrotia subaequalis (Hamamelidaceae), a rare and endangered tree species in China

Parrotia subaequalis (H. T. Chang) R.M. Hao & H.T. Wei is a rare and endangered Tertiary relict tree that is endemic to subtropical China. However, little is known about its growth condition and relationship with associated tree species. Here, for the first time we measured the structural diversity of P. subaequalis communities at three representative sites in eastern China using four structural indices, including mingling, tree-tree distance, and diameter and tree height differences. The results showed that: 1) Collectively, most P. subaequalis and associated tree species were small and mid-sized classes in tree height, and small-sized class in diameter; 2) There were two or more other tree species around most of P. subaequalis individuals across the three sites; 3) Overall, the mean distance between reference trees and their neighbors was mainly 1–2 m. Our results indicated that a strong interspecific competition existed between P. subaequalis and its associated tree species. Meanwhile, although the reference tree P. subaequalis had slight advantages in both horizontal and vertical planes, we think that it is necessary to take some effective measures to reduce the interspecific competition and thereby keep it at a proper successive stage. In addition, we also discuss the protection level of P. subaequalis in China, and propose to keep this species at the First-Grade State Protection.
The Impact of Natural Calcium Carbonate and Ubiquinone on Bone Mineral Density in Rabbits

This study investigates the effect of Ubiquinone and/or calcium carbonate (CaCO3) on bone mineral density (BMD) in rabbits at the healing site in mandibular bone postoperatively. Sixty healthy white male New Zealand rabbits (almost the same age [5-6 months], weight [2.0±0.25 kg] and circumstance) were used in this study. The heavy-duty dental engine drilled a mandibular groove of 2mm diameter and 6mm length in all animals. Postsurgery, the rabbits were randomly divided into six groups (10 each) according to the treatment. According to the evaluation period, each group was further subdivided into two subgroups (5 rabbits each); 15 and 30 days. The groups included; control group (the groove was not filled by anything) and treated groups which included five groups as follows: group I (in which the groove was filled with Ubiquinone), group II (groove was filled with CaCO3), group III (groove was filled with CaCO3: Ubiquinone as a ratio [1:1]), group IV ( groove was filled with CaCO3: Ubiquinone as a ratio [1:2]) and group V (groove was filled with CaCO3: Ubiquinone as a ratio [2:1]). The BMD was measured using Densitometry after 15 and 30 days. Statistical analysis showed significant differences at p≤0.05 in bone mineral density (BMD) between the control group (92±0.15) and all other treated groups except group III (125±3.54) and group IV (126±5.13) showed no significant differences at follow-up times at 15 days. Also, in the present study, we found there is a significant difference in bone mineral density among the control group (109±1.25), group I (144±3.45), group II (153±6.24) and group V (182±12.56) groups respectively. ANOVA test showed no significant difference in group III (160±8.94) and group IV (165±9.11) at follow-up times at 30 days. Adding the Ubiquinone and/or CaCO3 showed a significant increase in BMD manifested by bone healing like space-filling, newly formed bone trabeculae and a high number of lacunas compared with the control group. It can be concluded that, the Addition of Ubiquinone and/or CaCO3 to the mandibular fracture has a favourable effect on BMD and enhance bone healing in rabbits. ــــــــــــــــــــــــــــــــــــــــ ـ
Short-term effects of carrying a school bag on the distribution of force and plantar pressure during walking of children of different levels of physical activity

Introduction: Carrying a school bag is a dominant activity that a child performs during daily productive activities. The aim of the research is to examine how carrying a school bag of different weights affects the distribution of force and plantar pressure during normal walking on the flat terrain of children of varying levels of physical activity.Methods: The pilot study included 124 students aged 11-12 from Banja Luka. According to the protocol, each group of respondents was treated with an intervention-customized school bag and a comparator-school bag that the child only opted for. For the research, the Physical Activity Questionnaire for Older Children, measurement of anthropometric parameters, school bag weight, and Zebris tape (Zebris Medical GmbH, Germany) were used for gait analysis.Results: Inactive children achieved the lowest and active children’s highest walking speed during normal walking without a bag, with their customized school bag. When carrying a custom school bag: The highest maximum force is projected on the left heel 330.72 N in inactive children, and the lowest 265.93 N in moderately active children, the highest maximum pressure on the left heel is registered in inactive children, 27.60 N/cm2, and the lowest 21.85 N/cm2 in moderately active children. The maximum force-time of % of standing time on the left foot in the middle part lasted the longest in inactive children, and the shortest active children carried their school bag 40.31% and a custom school bag 39.76%. Conclusion: High physical activity and individual adjustment to distribute the burden well allow the child to adequately respond to the loads carried by the weight of the school bag.
Combined chlorophyll fluorescence techniques to study environmental impact on the mountain moss Polytrichum commune

Two chlorophyll fluorescence (ChlF) methods were used to study the effects of high light (photoinhibition) and dehydration, common stressors of the alpine environment, on primary photosynthetic processes in the moss Polytrichum commune from the Czech Republic, the Jeseníky Mountains. Photoinhibition (PI) was studied in fully hydrated thalli of P. commune and during the period of spontaneous desiccation. Time courses of Kautsky kinetics (KK) of ChlF and derived parameters: maximum quantum yield (FV/FM), effective quantum yeld (ΦPSII), and non-photochemical quenching parameters, were measured before and after the samples were treated with high light (1500 µmol m-2 s-1 PAR) for 60 min. Dehydration effects were tested in two sets of experiments with a Pulse-Amplitude-Modulation fluorometry (PAM) and Fast Chlorophyll Fluorescence induction curve (OJIP) techniques. In PAM tests, the desiccating samples were exposed to saturating light pulses every 10 min. in order to obtain ΦPSII and non-photochemical quenching (NPQ). In the second dehydration experiment, OJIP transients of ChlF were repeatedly recorded, OJIP-derived ChlF parameters were plotted against relative water content (RWC) monitored during desiccation. Combined ChF techniques provided insights into the mechanisms activated during P. commune desiccation, such as dissipation of excess absorbed energy through heat dissipation, and conformational changes or destructions of the light harvesting complexes. Combination of stressors resulted in amplified interference with the photosynthetic machinery, even when the added stressor (dehydration) was applied in low dose.
PSYCHOMETRIC EVALUATION OF FLOOD DISASTER MANAGEMENT QUESTIONNAIRE: CONFIRMATORY FACTOR ANALYSIS AND ITEM RESPONSE THEORY ANALYSIS

Flood disaster is the commonest natural disaster with huge impact on healthcare services in Malaysia. The FloodDMQ-BM© questionnaire was developed as a tool to assess the knowledge, attitude, and practice of healthcare providers regarding patient management during a flood disaster. We aim to further validate the FloodDMQ-BM© questionnaire by using Confirmatory Factor Analysis (CFA) and Item Response Theory (IRT). This cross-sectional study involved doctors, nurses and paramedics working in the Emergency Department of Hospital Universiti Sains Malaysia, Hospital Raja Perempuan Zainab II and Hospital Kuala Krai. Respondents were required to complete the FloodDMQ-BM© questionnaire. The responses were analysed by using CFA and IRT to establish its validity and reliability. A total of 215 respondents participated in this study. CFA analysis with Maximum Likelihood Robust as the estimation method, on the attitude and practice components resulted in good factor loadings (>0.5) in nearly all items and excellent model fit indices values (CFI = 0.96-0.98, TLI = 0.95-0.96, SRMR = 0.04-0.05, RMSEA = 0.07). Meanwhile, IRT analysis on the knowledge section showed a good two-way marginal fit based on S-X2, and a good model fit with RMSEA of 0.08. Based on the 2PL model by using the IRT assessment of the knowledge section, one item in the knowledge section (K3) was removed (chi-squared residual >4) resulting in improved model fit. The included items had well-standardized loadings (>0.3) and marginal reliability of 0. 651.Our results confirmed that the FloodDMQ-BM© questionnaire displayed valid and reliable psychometric properties.
Competitiveness of agri-food foreign trade in conditions of the Slovak Republic

The presented paper aims to evaluate the development and competitiveness of agri-food foreign trade of the Slovak Republic for the period 2016 – 2020. In the article, we present the priorities of Slovakia within the commodity structure. We use the RCA indicator to identify comparative advantages. In this paper, we also compare the actual and estimated development of agri-food foreign trade of the Slovak Republic in the years 2018 – 2020. Based on the reached results, we can state that we achieve an ever-increasing trade balance deficit in agri-food foreign trade. Produced results confirmed all the research assumptions presented in the paper. Despite the increase in export and import of agri-food products, the negative trade balance is still deeper. A significant deviation of real development from the predicted values can be explained by the influence of the worldwide pandemic of the coronavirus COVID-19, which slowed down the possible further development of agricultural trade.
A prospective study of demographic and socioeconomic factors responsible for non-acceptance of family planning methods at tertiary care teaching hospital, Gujarat, Indiaal, Gujarat, India

Background: Population explosion has been major challenge for India since Independence. The adoption of contraceptive methods remains the best solution to this problem. The objective of this study was to determine the factors for non-acceptance of different contraceptive methods among married women of postnatal ward in tertiary care hospital, Ahmedabad, Gujarat, India. The aim of the study was to analyse about the level of awareness and attitude towards different methods of contraception among married women of reproductive age groups.Methods: It was a prospective observational study carried out in the department of obstetrics and gynaecology, B. J. Medical College, Civil Hospital, Ahmedabad, Gujarat, India, a tertiary care teaching hospital from June 2019 to November 2020. 200 patients meeting inclusion criteria were included. Case sheets were analysed to obtain data regarding reasons for non-acceptance of contraceptive methods.Results: In our study, we found that among study population 64% women use family planning methods, which was still low as compared to developed countries. 36% women were non-users in study population. The main reason of non-acceptance of contraceptive method were desire for male child, non-allowance by religion/custom, the myth regarding price of contraceptive method, desire of more children and worry about side effects.Conclusions: To increase the use of contraceptive among women, we can increase awareness about different family planning method with counselling about various available contraceptives. It is also important to increase participation of husbands as they often influence the decision regarding reproductive health of women.

Genetic diversity among asexual and sexual progenies of Phytophthora capsici detected with ISSR markers

The population structure of Phytophthora capsici among asexual and sexual progenies was analyzed using ISSR. Thirty asexual progenies of one parent and three sexual populations were assayed for genetic diversity using 5 ISSR primers and DNA from 120 offspring of P. capsici was amplified. In total, 71 reproducible ISSR fragments were obtained, of which 100% were polymorphic, revealing high polymorphism among the isolates. Among them, the percentages of polymorphism of sexual and asexual progeny isolates were 100.00 and 77.46%, respectively. Genetic similarity coefficients among all the isolates ranged from 0.54 to 0.73. The sexual offspring population showed much more variability than the asexual offspring population with 76.26% variability attributed to diversity within populations as compared with 23.74% among populations. This research reveals that the sexual progeny population of P. capsici contributes more genetic diversity than that of asexual progeny population.
Population Structure, Growth Dynamics, Leaf Production and Soil Conditions of Megaphrynium macrostachyum, a Key Non-Wood Forest Product in Central Africa

Aims: Megaphrynium macrostachyum is a key non-wood forest product (NWFP) in Central Africa. This study aims to describe the soil characteristics and behaviour of the species Megaphrynium macrostachyum in a fallow land in southeastern Gabon. Methodology: Leaf growth was monitored weekly on a sample of 60 leaves for 10 weeks, after the unrolling of horns. Population structure and leaf production were quantified on 64 m² plots and then extrapolated to the hectare. Soil samples were collected at 30 cm depth. Results: Leaf growth and stem enlargement were observed to take place during the horn stage, while stem elongation became active after this stage. The stem reached its maximum height about 60 days after the leaf had fully unrolled. Within the same population, leaf length and leaf width were less heterogeneous (on average 55.6 ± 5.9 cm and 35.5 ± 4.5 cm, respectively); whereas leaf area, stem diameter and stem height were quite heterogeneous (on average 1475 ± 328.3 cm², 9 ± 2.2 mm and 154 ± 33.3 cm, respectively). Megaphrynium macrostachyum was observed to colonise its environment quite well (148,646 ± 66,623 stems per hectare), thus explaining its high leaf production (104,167 ± 45,271 usable leaves per hectare). The soil sample analysed revealed Megaphrynium macrostachyum to grow in sandy-silty or sandy-silty-clay soils (58.21% sand, 25.69% silt and 16.1% clay), and in soils that are wet (35% relative humidity), acidic (pH 4.01), low in phosphorus (9.38 ppm assimilable phosphorus) and total nitrogen (0.01% total nitrogen), and high in organic matter (19.3% organic matter). Conclusion: The leaf area exploited by local populations is variable. Megaphrynium macrostachyum is less demanding on soil characteristics, with high leaf production. From a cultivation perspective, the horn stage would be decisive.

AIM: The present study aimed to compare the clinical efficiency of facial pressure bandage, to that of intramuscular injection of dexamethasone (8 mg) on postsurgical sequels (swelling, pain, and trismus) of extraction of impacted mandibular third molar. METHODS: The study implemented a randomized split-mouth design. Patients with symmetrical bilateral impacted molars were eligible for the present trial. Sides were randomly assigned to two groups: pressure bandage group and dexamethasone group. The evaluated postsurgical sequels were extraoral swelling, trismus, and pain after 48 h and 7 days. RESULTS: The study included 42 impacted third molars (n = 42) in 21 patients with a mean age of 23.4 years. Most participants were females (66.7%). The mean postoperative swelling rates after 48 h and 7 days in pressure bandage group were found to be comparable to those of dexamethasone group. No significant difference was found in the mean rates of postoperative trismus between study groups after 48 h and 7 days. Differences in mean pain level scores between the pressure bandage group and dexamethasone group were statistically insignificant after 48 h and 7 days. CONCLUSION: The study findings showed that the effect of the pressure bandage was comparable to dexamethasone effect on the postsurgical sequels after surgical extraction of impacted mandibular third molars.

Evaluation of ultrasound pretreatment and drying methods on selected quality attributes of bitter melon (Momordica charantia L.)

ABSTRACT Recently, numerous attentions have been drawn to bitter melon (Momordica charantia L.) processing due to its outstanding pharmacological properties. Fresh and ultrasound pretreated bitter melon slices were subjected to hot air drying (HAD) and radio frequency assisted hot air drying (RFHAD) in this study. Quality attributes of the dried samples were compared in terms of moisture content, water activity, glass transition temperature, color, rehydration ratio, and content of chlorophyll, ascorbic acid, and total phenolic. Compared with HAD process, results showed that the use of ultrasound pretreatment and RF heating accelerate water loss during drying processes, and then contribute to a shorter drying time, a lower water activity and higher glass transition temperature of dried samples. It also showed RFHAD had better color exhibition, higher retention of chlorophyll, ascorbic acid, and total phenolic due to uniform heating and shorter drying time. Additionally, ultrasound pretreatment greatly improved the rehydration capacity and total phenolic retention. Therefore, considering the quality attributes and drying time, ultrasound pretreatment and radio frequency drying would be very promising alternatives for food processing.
Heavy metals tolerance in bacteria from industrial wastewater

The incidence of chemical stressors in industrial waste effluents has culminated in the re-engineering the genetic and metabolic characteristic of resident microbiota. Microbial adaptability enables them to tolerate these stressors however, propelling the phenomena of acquisition of heavy metal resistance which may also incite resistance to antibiotics. Waste water from industrial establishments may travel from site into surrounding communities via canals and waterways thus, disseminating these stressors as well as resistance in the environment. This study seeks to investigate the physicochemical and heavy metal composition of industrial effluent and its tolerance in resilient bacteria from the study area. Physiochemical analyses revealed pH level which ranged between (5.8-10.87), BOD (6.612-16.01 mg/l), TDS (937.226-2173.49 mg/l), Sulphates (658.72- 1342.28 mg/l), Nitrates (11.46-70.16 mg/l), Phosphate (3.03-8.43 mg/l) exceeded the NESRA limits; Cu (0.024-4.521 mg/l) Cd (0.002-6.41 mg/l), Pb (0.001-8.151mg/l), Zn (0.511-6.092 mg/l). All the isolates showed marked tolerance to Cu, Cr, Pb, Cd and Zn at concentrations between 200 and 500µg/ml, except Alkanindiges sp. 5-0-9 and Bacillus altitudinis which were not susceptible to all the heavy metals at all concentrations. This study revealed the incidence of heavy metal resistance among bacterial isolates from industrial wastewater, the incidence of which could give rise to co-occurrence with antibiotic resistance thus, aggravating a public health concern.
