Abstract

Cyclophosphamide (CP) is a chemotherapeutic agent that belongs to the alkylating agent group that is widely used in the treatment of cancer. Cardiotoxicity is often a side effect of using CP in medical therapy. In this study, 24 Sprague Dawley rats were randomly divided into 4 groups. Group 1 (K1) was given injection with aqua pro injection intraperitoneally (IP) once a week for 21 days. Group 2 (K2) was given IP CP with a dose of 50 mg/kg BW, once a week for 21 days. Group 3 (K3) was given boswellic acid extract at a dose of 250 mg/kg BW orally, every day for 21 days. Group 4 (K4) was given boswellic acid nanoparticles at a dose of 250 mg/kg BW orally, every day for 21 days. During the treatment the body weight of the rats was weighed every day. At the end of the treatment, the rats were euthanized and blood samples were taken for blood biochemical evaluation, namely CPK, LDH, AST, and ALT. The results showed that the levels of CPK, LDH, AST, and ALT in K2 were significantly higher (p<0.05) than K1, K3 and K4. Statistically, the results of CPK, LDH, AST and ALT in K3 and K4 were not significantly different (p<0.05) compared to K1. The two groups (K3 and K4) were not significantly different (p<0.05) but on average the CPK, LDH, AST, and ALT results in K4 had lower scores than K3. This can indicate the protective effect of boswellic acid and boswellic acid nanoparticles on the heart against cyclophosphamide-induced cardiotoxicity.

Abstract

Unambiguous provision of results in different environments and conditions by machine learning algorithms is an unresolved problem until now. Solving the problem of machine learning with unambiguous provision of results in different environments and conditions can be approached by focusing on the psychophysical holographic process of human learning. A person, with a mental concentration of attention, experimentally teaches vision, hearing, psyche and mind in a holographic way and in a resonant way to perceive, recognize and recognize phenomena, processes, objects, subjects, meanings, music and other entities in various environments and conditions. A person experimentally teaches the psyche and feelings to rationally navigate in various environments and conditions. Holographic algorithms of experienced machine learning will help neural network ensembles to unambiguously recognize objects, subjects, music, texts in various environments and conditions using a model of recognizing their own or someone else's. Machine learning simulates holographic processes of human communication memorization of entities. Searching for objects in different environments in different conditions based on experienced machine learning simulates resonant associative processes of human entity detection. By simulating holographic processes of the human psyche based on artificial intelligence of machine learning with Fourier transformation, using full parametric sequences of necessary and sufficient data of holograms of target objects, it is possible to solve the problem of their unambiguous detection in different environments and in different conditions.

Abstract

The viscoelastic properties of asphalt concrete are susceptible to the variation in the pavement temperature. In the present work, asphalt concrete beam specimens were prepared at optimum binder content and tested under repeated flexural stresses for fatigue life. Three testing temperature were implemented (5, 20, and 30) ℃. The variation in the phase angle, dissipated energy, flexural stiffness, and permanent deformation due to the testing temperatures were monitored and modeled. It was concluded that the viscoelastic properties of asphalt concrete are highly sensitive to the variation in testing temperature. The phase angle and the permanent deformation increases sharply as the testing temperature rises. However, the dissipated energy and the flexural stiffness declines as the testing temperature rise. Mathematical models were obtained which can be implemented in identifying the thermal behavior of the viscoelastic properties of asphalt concrete.

Abstract

The objective of this study was to evaluate the effect of the nature of the food ration on the size, weight, weight gain and ex situ reproduction of the snail (Achatina achatina) in Gbado-Lite. The results of this work show that variations in size [from 8.2±1.2 cm at feeding (D0) to 9.9±2.1 cm at day D84 (snail farm A) and from 8.4±1.1 cm to 10.2±1.8 cm (snail farm B)]; hatching rate [88.2% (snail house A) and 94.2% (snail house B)]; weight [460±18.5 g at loading (D0) to 760±26.3 g on day D84 (snail house A) and 475±10.9 g to 760±26.3 g (snail house B)]; mean absolute weight gain 84 days after loading [37.7±12.0 g (snail house A) and 36.5±9.6 g (snail house B)] were not statistically different between snail houses including mean daily weight gain (0.450±0.1 g/d vs. 0.363±0.1 g/d) and survival rate (90% vs. 100%). Both formulations have the same effect on the reproduction of Achatina achatina in captivity. It is therefore desirable that more in-depth studies be conducted with the aim of popularizing this non-conventional breeding in the city of Gbado-Lite. Thus, in the current context of biodiversity erosion linked to human activities as well as environmental factors, snail farming can contribute to empowerment, improved socio-economic conditions and household resilience to climate change.

Abstract

The purpose of this study was to conduct a survey of edible caterpillars and the ethno-medical value of their host plants in Gbado-Lite using the "snowball" sampling technique. The results of this study show that Anaphe panda, A. venata, Elaphrodes lactea, Imbrasia epimethea, I. oyemensis, I. truncata and Pseudanthera discrepans are the most consumed caterpillars. Drying is the most used preservation method (82.4%); ground collection is the most used harvesting method (86.3%) while evisceration (45.1%) and dehairing (33.3%) are the main cooking methods used. Harvesting is done more in the forest (94.1%) from May to July (86.3%). The vast majority (98%) of host plants are used in traditional medicine; leaves (53%) and bark (45%) are the most used parts, while decoction is the most used method of preparing therapeutic recipes (92%). The felling of trees (39%) and traditional agriculture (26%) are to varying degrees the main causes of the disappearance of edible caterpillars and their host plants. Incomplete cooking (78.4%) and/or the host plant (19.6%) are the main causes of consumer poisoning. It is therefore desirable that sustainable participatory management strategies for edible caterpillars and their host plants be put in place in North Ubangi Province. These include community agroforestry, which should be practiced in peri-urban areas in order to strengthen the resilience of communities to climate change while at the same time fighting hunger and poverty. Indeed, the domestication of species would allow annihilating the pressure on wild resources, to conserve them, to fight against deforestation and to ensure the availability and sustainability of edible caterpillars. Those phytochemical, pharmacological and toxicological studies could be carried out on host plants in order to identify compounds of medical interest contained in these plants.

Abstract

Household solid waste management is a crucial issue for environmental and human health. The purpose of this study was to conduct a survey on household solid waste management in Gbado-Lite (Nord-Ubangi) in the Democratic Republic of Congo (DRC). A household solid waste survey was conducted in 5 neighborhoods of the city of Gbado-Lite in northern DRC from July to August. Data collection was made possible by stratified probability sampling and direct observations. The results of this study revealed that the main informants (75%) were women and 68% of the respondents were in the 18-35 age group. The main socio-cultural groups in the study area are the Ngbadi (55%) and Ngbaka (16%). In addition, 74% of respondents have secondary education and their main sources of income are commerce (25%), the civil service (20%) and the household (13%). Also, the main solid household wastes identified were organic materials (44%) and packaging (25%); the majority (56%) of respondents did not have garbage cans and used plastic buckets without lids as their main garbage can (75%). Almost all (98%) of the waste does not undergo primary separation. The main waste disposal methods used by households are: landfill (43.87%), abandonment on public land (30.62%) and incineration (18.36%). Finally, the main harms of waste reported are: typhoid fever (29%), malaria (25%) and mosquito proliferation (24%). It is therefore desirable that a public sanitation service be set up in Gbado-Lite to enable households to manage their solid waste properly and thus protect the urban environment and human health.
