The detailed groundwater flow and water chemistry to illustrate landscape structure of the infertile peatless mire by using piezometers and groundwater wells were measured. The instruments were installed in lines through a small spring-fed wetland underlying little peat from the hillslope to the valley bottom in southwestern Japan. Flow net and EC data clearly indicated that the wetland was situated in a high-EC groundwater upspring area. The low-productivity graminous vegetation was related with four hydrological factors such as: (1) high water level; (2) low-EC(o s/cm) groundwater; (3) weakly upward hydraulic gradient; and (4) overflowing of negatively pressured groundwater. In other words, the “old or deep groundwater” constructed the foundation of slope-wetland, and maintained the high groundwater level. In contrast, overflowing “youthful groundwater” is supplied from head of slope-wetland preferentially through the shallow substratum. The plant communities of the peatless mire in southwestern Japan are similar to those of raised bog in northern cool temperate Japan. There have been some reports verifying that the underlying mineral substrata of such wetlands were quartzile rocks such as granite, rhyolite, chart and well-leached sand. Results showed (1) low cation availability affects the water acidity; (2) upward seepage of high-EC groundwater composed the foundation of the investigated peatless mire; and (3) the poor mineral condition seems to play a similar role to northern ombrotrophic(rain-fed) condition.

Background: As the coronavirus spared accelerated, various sectors began to deteriorate since the early stages of the CoVID-19 pandemic. The health sector as one of the major areas where the pandemic put a huge strain was also affected in different ways. Precisely, patient adherence to medication despite difficulties was a point of a question for health staff. Thus, this survey aims to distinguish and discuss the possibility of patients with chronic medications receiving their drugs and taking them regularly as prescribed. Method: Two online questionnaires were generated using Google forms and distributed among patients with chronic illnesses and pharmacists in the Khartoum locality. The survey was conducted during the period of the study to get the most recent data. Results: 81.4% of the population stated that they did encounter difficulties in obtaining their chronic medication during the pandemic. Pharmacists reported that drug availability decreased by 87% in pharmacies, but a considerable proportion of patients adhered to their medications (84%), and obtained their medications through a variety of means. More than half of the patients ordered their medication illegally, in addition to another approach discussed in the paper.

Tibial fractures are one of the most frequent bone fractures caused by accidents or falls because of the tibia’s slender shape. In the tibial fractures close to the joint surface, a plate and screws may be the ideal method of fixation. While using the plate and the screws the estimation of the stress on the plate and screw gains importance before beginning the treatment. In this study, it is aimed to conduct a numerical simulation which uses finite element methodology, to estimate the von Mises stress subjected to the plate and screw which is used in tibia fracture treatment. A titanium plate and 4 screws on it are used for treatment of the fracture. The fracture angle varies as 0°, 15°, 30°, and 45°. The compressive force affected on the plate is estimated to be 750 N. Moreover, the bone is simulated 3D, by using commercial software, ANsys structural.

Introduction: Members of the Human Epidermal Receptor [HER] family of receptor tyrosine kinases, such as HER2 and EGFR proteins are overexpressed in several epithelial malignancies and serve as effective therapeutic targets in cancer management. However, their role in prostate cancer development has been sparingly explored and with contrasting findings. Notably their relationship with prostate cancers cases seen in sub-saharan Africa is yet to be explored. Design: A retrospective study involving histologically diagnosed cases of adenocarcinomas of the prostate. Cases were classed according to the WHo/IsUP Gleason Prognostic groups [G1 - G5]. Immunohistochemical analysis was performed using monoclonal antibodies for HER2 and EGFR, while in situ hybridization employed DNA probes for the corresponding genes. scores of +2 and +3 were regarded as positive for both antibodies, while a target gene: centromere ratio of >2 was set as the threshold for amplification. Results: A total of 44 cases were included in the study. The acinar type was the commonest morphologically, with Gleason group 5 [Gleason scores 8 - 10] accounting for close to half of the cases [47.7%]. The HER2 antibody stained negatively in the majority of cases [93.2%], being positive in only 3 [6.8%] of cases seen. High level expression of EGFR [+2/+3] was observed in 25% of cases, low level expression was identified in 6 [13.6%] cases. All HER2 positive malignancies displayed overexpression of EGFR. In situ-hybridization revealed the absence of high level amplification for both HER2 and EGFR, while polysomy was not detected in any of the cases. Conclusion: The overexpression of EGFR in prostate cancers has been demonstrated in a native African population, affirming its suitability for targeted therapy. overexpression of HER2 in prostate cancer is inconstant, and amplification of the HER2 gene is less frequent than as compared to malignancies of the Breast and ovary. There’s a need for a standardized protoco
