Phytoremediation, tolerance and bio-accumulation potentials of lead in the roots and shoots of Pteris vittata and Pityrogramma calomelanos were investigated to ascertain the effects of lead on thee species’ growth and development. Within the experiment, 5 kg of air dried and sieved soil was put inside six plastic pots labelled CT, A, B, C, D and E, each with different concentrations (0, 200, 400, 600, 800 and 1,000 ppm) of lead (II) trioxonitrate (v) salt. The shoots and roots of the plants were air dried, grounded and analysed for lead quantities using x-ray fluorescence before and after the treatments. One-month old healthy fernlets of each species were transplanted into each of the pots, in six replicates. Growth parameters such as leaflet area, number of leaflets and frond height were recorded weekly, for 12 weeks. Quantitative data were analysed for significant difference using analysis of variance for each of the plant species and means were evaluated with Duncan's multiple range test for frond height, leaflet number, leaflet area, roots and shoots biomass. Negative effects (decrease) on the growth parameters were observed in both species. Pteris vittata accumulated more lead in all the treatments, in both shoots and roots, compared with Pityrogramma calomelanos. The highest bio-accumulation factor in Pteris vittata shoot was 2.944 and 0.635 in Pityrogramma calomelanos.Transfer factor of Pteris vittata was 1.742, while for Pityrogramma calomelanos was 0.859 in all the treatments. It could be concluded that Pteris vittata is a better bio-accumulator, tolerated more lead and therefore could be used in remediating lead-contaminated soils, better than Pityrogramma calomelanos.

The high cost of purchasing inorganic fertilizer and its impacts on the soil and the environment remains a major concern in environmental management. Consequently, there is the need to explore other ways to enhance soil fertility. The study investigated the effects of Bambusa vulgaris Schrad. and Gliricidia sepium (Jacq) charcoal powders on the growth of Parkia biglobosa (Jacq). Benth seedlings. The experiment was laid out in a Completely Randomized Design (CRD) with 13 treatments and 9 replicates each. Seeds were sowed directly into polyethene pots while the various treatments were added a week after sowing seeds. Watering was done daily while weeding was done periodically. Growth parameters of seedling height (cm), stem diameter (mm) and leaf count were assessed weekly for 16weeks. Data collected was subjected to Analysis of Variance (ANOVA) at 5% level of significance while the means were separated using Duncan Multiple Range Test (DMRT). The result obtained showed that 15g of Gliricidia sepium charcoal powder + 2kg of topsoil) performed best in height and leaf production with values of 15.85cm and 20.58 respectively.5g of Bambusa vulgaris charcoal powder + 2kg of topsoil) performed best with the value of 0.41mm for stem diameter.2kg of topsoil had the least performance for all parameter assessed. The ANOVA result showed that there was significant difference at P>0.5 among the treatments at 5% level of probability in terms of plant height, stem diameter, leaf production. The study concludes that the addition of charcoalas soil additive enhanced growth of Parkia biglobosa seedling at nursery stage.

Arsenic (As) is an ubiquitous trace metalloid found in all environmental media. Its presence at elevated concentrations in soils derives from both anthropogenic and natural inputs. Arsenic is a toxic and carcinogenic element, which has caused severe environmental and health problem worldwide. Technologies currently available for the remediation of arsenic-contaminated sites are expensive, environmentally disruptive, and potentially hazardous to workers. Phytoextraction, a strategy of phytoremediation, uses plants to clean up contaminated soils and has been successfully applied to arsenic contaminated soils. It has the advantage of being cost-effective and environmentally friendly. A major step towards the development of phytoextraction of arsenic-impacted soils is the discovery of the arsenic hyper accumulation in ferns, first in Pteris vittata, which presented an extraordinary capacity to accumulate 2.3% arsenic in its biomass. Another fern, Pityrogramma calomelanos was found to exhibit the same hyperaccumulating characteristics. After that, screening experiments have revealed that the Pteris genus is really unique in that many species have the potential to be used in phytoextraction of arsenic. In general, these plants seem to have both constitutive and adaptive mechanisms for accumulating or tolerating high arsenic concentration. In the past few years, much work has been done to understand and improve the hyperaccumulating capability of these amazing plants. In particular, the field of molecular biology seems to hold the key for the future of the phytoremediation.

Background: Changes in oral health like tooth loss can have a profound effect on the patients’ quality of life. The condition of relative or complete toothlessness exerts negative effects on chewing, speech, and appearance of the individual. The high capability of dental implants in restoring the beauty and oral function of the patients has led to their widespread usage. This study aimed to compare the quality of life of the toothless patients before and after treatment with implant. Methods: In the present study, 50 patients afflicted with complete or relative toothlessness were examined. Before completing the questionnaires, all participants were asked to complete and sign the consent form of the questionnaire from Oral Impacts on Daily Performance) OIDP). The questionnaires were completed before receiving the implant coating, and a month after the delivery of the patients’ prosthesis. Finally, the data were analyzed using SPSS statistical software, ANOVA, Mann-Whitney, and McNemar. Results: In this study, 50 patients with the mean age of 46.84±11.87 years were investigated. As for the gender and marital status of the participants, 50% (25 patients) were male and 84% (42 ones) were married. According to the data obtained from the OIDP questionnaire, the most significant changes were detected in eating, smiling, laughing and showing teeth without discomfort and speaking clearly, respectively. Moreover, a significant difference was found between the total score of oral effect on daily activities and some levels included in disruption questionnaire on daily activities such as eating, speaking clearly, going out, sleeping, relaxation, smiling, enjoying communication with others, job-related activities, as well as emotional conditions (Irritability); however, no significant difference was found between cases of cleaning teeth and light physical activity. Conclusions: According to the data from OIDP questionnaire and the study results, implant had favorable effects on the quality of life of the patients. However, long-term studies and follow-ups are necessary to determine other possible favorable effects of implant treatment.

Salinitas tinggi dan genangan dapat terjadi pada tempat dan waktu yang sama; meskipun demikian pemahaman terhadap pengaruh kedua kondisi tersebut terhadap pertumbuhan, respon morfologis, dan anatomis kelapa sawit masih sedikit. Telah dilakukan penelitian dengan mengkombinasikan 2 aras salinitas (non salin dan salin) dan tiga taraf genangan (tanpa genangan, interval genangan 2 minggu, dan interval genangan 4 minggu). Penelitian dilakukan dalam pot selama 4 bulan dengan bahan tanam kelapa sawit berumur 4 bulan. Parameter pertumbuhan dianalisis dengan analisis varian dan dilanjutkan dengan uji jarak berganda Duncan pada jenjang nyata 5%. Pengamatan visual secara langsung dan pembuatan preparat melintang akar dilakukan untuk mengetahui perubahan morfologi dan anatomi tanaman. Hasil analisis menunjukkan salinitas tinggi dan genangan konsisten menurunkan parameter pertumbuhan kelapa sawit. Salinitas tinggi dan genangan tidak secara konsisten mengubah rasio luas masing-masing jaringan penyusun akar primer, sekunder, dan tersier. Kelapa sawit membentuk pneumatophore dan saluran aerenkima pada kondisi genangan, baik non salin maupun salin. Mekanisme adaptasi terhadap genangan tersebut dapat menurunkan pengaruh negatif cekaman salinitas tinggi. High salinity and waterlogging can occur at the same place and time; however, the effects of these two conditions on growth, morphological, and anatomical responses of oil palm was not fully understood. A research had been done by combining two levels of salinity (non saline and saline) and three levels of waterlogging (without waterlogging, two-week waterlogging intervals, and four-week waterlogging intervals). The study was conducted in pots for 4 months used 4 months old oil palm planting material. The growth parameters were analyzed by analysis variance continued by Duncan multiple-range test at 5% level of convidence. The morphological and anatomical changes of plants were observed trought direct observation and root cross section. The results showed that high salinity and waterlogging consistently decreased the oil palm growth parameter. High salinity and waterlogging did not consistently change the ratio of the area of each primary, secondary, and tertiary root tissue. Palm oil formed pneumatophores and aerenchyma under both non saline and saline waterlogging. Adaptation mechanisms to these waterlogging could reduce the negative effects of high salinity stress.

Introduction: Hyposalivation is a common problem experienced by head and neck (H&N) cancer patients undergoing radiotherapy. Hyposalivation can cause negative effects on the physical aspects of making oral mucositis, pain during eating and talking as well as psychological effects that cause feeling of discomfort sadness and, ultimately, depression. Many nonpharmacological interventions can be done for hyposalivation that occur in patients, among which are chewing gum and cryotherapy because they are easy to do, easy to access, inexpensive and have minimal side effects. However, the effectiveness of these interventions is not yet clear. Hence, this study is aimed to determine the effectiveness of chewing gum versus cryotherapy to increase salivary volume in H&N cancer patients undergoing radiotherapy.Methods: A quasi-experimental time series group design to determine the most effective time to influence the increase in salivary volume. This research was conducted on 36 respondents H&N cancer undergoing radiotherapy with four times measurement are pretest-posttest on the 3rd, 5th, and 7th day of intervention between February and March 2020. Subjects were chosen using consecutive sampling. Chewing gum group will chew gum six (6) pieces/day and cryotherapy group will suck on ice cubes five (5) minutes before and after radiotherapy. The spitting method was used to collect saliva and the data were analyzed using General Linear Model-Repeated Measure (GLMRM).Results: Chewing gum is more effective to increase salivary volume than cryotherapy. The GLMRM within subjects at four (4) times measurement showed a significant difference between chewing gum and cryotherapy group with p value <0.05 on the 7th day. Subjects in the chewing gum group had better salivary volume increment than cryotherapy group.Conclusion: This study showed that chewing gum is more effective to increase salivary volume on patient H&N cancer undergoing radiotherapy because chewing gum has higher salivary volume increment than cryotherapy groups

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.
