The changes of Chinese women in social economy

Under the leadership of the Chinese Communist Party, generation after generation of women have made pioneering efforts and contributed to China's construction, reform and development. In the great leap of the Chinese nation from standing up, becoming rich to becoming strong, great changes have taken place in the status of Chinese women. On the one hand, the old feudal ideas are gradually broken down and new education and ideas are deeply rooted in the hearts of the people. On the other hand, economic development also needs and relies on the wisdom and strength of women to make continuous progress. Starting from the demographic indicators, this paper makes a gradual and progressive analysis of health and education. Finally, combining with the relevant contents of the female employment index report, this paper makes a prospect and puts forward some suggestions to promote the further development of the equal rights movement and women's cause.

Parasitoids of dipterans and hemipterans collected in to cultivate on maize in Brazil

This paper has the objective of relating the occurrence of parasitoids to cultivate on maize in Itumbiara, Goiás during the crop 2001. Four groups of parasitoids were collected: two Brasema sp. (Hyemnoptera: Eupelmidae), two of Conura sp. (Hymenoptera: Chalcididae), eleven Gryon gallardoi (Bréthes, 1913) (Hymenoptera: Scelionidae) and nine of Pteromalidae sp. (Hymenoptera: Pteromalidae). The most important obtained parasitoids were found in Leptoglossus zonatus (Dallas, 1852) (Hemiptera: Coreidae) with Brasema sp. and G. gallardoi, prevailing the parasitism of 26,8% and 4,8%, respectively. Hymenoptera is one of the largest orders of insects. The lesser known Hymenoptera are parasitoids that develop in immature stages of other arthropods. They are considered important in the biological control of insect pests.

Assessment of profitability and risk management in vegetable production in Ogun State, Nigeria

The study examined the performance and risk management of vegetable production in Ogun State, Nigeria. A multistage sampling procedure was used to select 120 respondents for the study. Data were collected through a well-structured questionnaire and personal interview schedule. Descriptive statistics and inferential statistics such as Ordinary Least Square (OLS) were used for the analysis of this study. The results found out that lack of discriminating pricing system, conflict in policy making, and high cost of inputs affect the market prices and as well serve as the main production risks that were observed by the farmers in the area. The average cost incurred for the production was about ₦6,908, while the total revenue accrued was ₦41,751. The gross margin and net farm income realized per production season were ₦36,973 and ₦34,843, respectively. The value (6.0) of return on investment showed that farmers realized times six of their investment. The variables such as household size, farm size, fertilizer application and equipment were the main determinants of vegetable production in the area. Also, the main challenges faced by the farmers were the infestation of pests and diseases, inadequate funds and climate change consequences. Therefore, it is recommended that the vegetable farmers should be encouraged through technical training on innovative approach to price determination and forming of functioning market structure in the area.

Phytochemical screening and antimicrobial activity of Haematostaphis barteri

The aim of this work was to carry out the phytochemical screening and antimicrobial activities of Haematostaphis barteri. The method of cold maceration was used in the extraction by serial exhaustive extraction method which involves successive extraction with solvents of increasing polarity from a non-polar (hexane) to a more polar solvent (methanol) to ensure that a wide polarity range of compound could be extracted. The results showed that flavonoids, terpenes, terpenes, tannins, and saponins are present in all the leaf extracts. The result of the antimicrobial activity obtained from the extracts of the leaf of Haematostaphis barteri revealed that all the crude extracts of the leaf inhibited or exhibited antibacterial activity against Salmonella paratyphi, Staphylococcus aureus, Escherichia coli, and Penicillium spp. All the extracts did demonstrate antimicrobial activity against Aspergillus niger. The plant H. barteri is commonly used traditionally for the treatment of diarrhoea, wound, headache, malaria, dysentery and fevers. The overall results confirm the significance of the use of the plant in traditional medicinal treatment of diarrhea, wound, headache, malaria, dysentery and fevers, in line with reported claims.

Mini review of parasitoids of insect pest in Brazil

In the process of manipulating agroecosystems, man adopts strategies that often conflict with those of the nature by imposing its interests and objectives to increase the food and fiber production. As a result, populations of certain species of herbivores, such as insects and mites phytophagous, become numerically so high that they damage the crops to the point of reducing their productivity and, consequently, their economic income. The aim of the mini review is to provide a bibliographic summary of parasitoids of the Order Hymenoptera collected from insect pests in Brazil. The research was carried out in studies related to the theme with emphasis on the quantitative aspects of the genera, and species (Taxonomic groups). A bibliographic search was carried out that contained papers published from 1998 to June 2021. The mini review was prepared in Goiânia, Goiás from March to June 2021 using the Electronic Scientific Library Online (Scielo) and internet. Thus, biological control aims to reduce the population level of a species classified as a pest, keeping it below the level in which it is capable of causing economic harm.

Phytochemical screening and evaluation of antioxidant activity of the stem bark of Anacardium occidentale L. and Vitellaria paradoxa C.F. Gaertn, two medicinal plants from Poro region (Northern of Côte d'Ivoire)

Anacardium occidentale and Vitellaria paradoxa are two medicinal plants traditionally used by Ivorian, particularly in the treatment of diabetes, arterial hypertension and diarrhea. The objective of this work was to evaluate the phytochemical constituents and the antioxidant activity of the stem barks of A. occidentale L. and V. paradoxa. The stem bark of both plants was used for the aqueous extraction. Major chemical groups were identified using the tube staining method followed by confirmation by thin layer chromatography (TLC). The antioxidant activity of the extracts was evaluated by DPPH method. The results of phytochemical screening of plant extracts revealed the presence of polyphenols, anthraquinones, tannins, sterols, terpenes and saponins. In addition, the evaluation of the antioxidant activity by spectrophotometry using the DPPH method showed that all extracts had significant and different antioxydant activity compared to the reference molecule (Vitamin C, IC50 = 0.80 ± 0.70 µg/mL) with respective IC50 of 0.42 ± 0.32 µg/mL for V. paradoxa and 0.87 ± 0.77 µg/mL for A. occidentale. V. paradoxa therefore has the best antioxydant activity. These results could explain the therapeutic virtues of A. occidentale and V. paradoxa in the treatment of various pathologies.

Effect of leaf extracts of Carica papaya (Paw paw) and Pakia biglobosa (African locust bean) on some biochemical parameters of albino rats

In spite of the advances made in orthodox medicine, there has been an increasing interest in herbal medicine. The leaves of Carica papaya and Pakia biglobosa have been reported to contain lots of beneficial medicinal compounds, hence their use in the traditional prevention, management and treatment of ailments/diseases. In this study, the effect of varied concentrations of the ethanol leaf extract of the plants on some biochemical parameters of albino rats was assessed. The phytochemical compositions of the leaves were determined using established standard laboratory methods. Fifty four male Albino rats weighing between 150g-200g were randomly distributed into nine groups of six animals each. A daily single dose of 500mg/kg, 1000mg/kg, 1500mg/kg and 2000mg/kg body weight of either of the extracts was respectively, administered to the eight test groups for fourteen days. The control group was given only feed and water. Biochemical parameters such as the serum activities of Aspartate Aminotransferase, Alanine Aminotranferase and Alkaline phosphatase as well as the serum concentrations of Bilirubin, Albumin, HCO3-, Urea, Creatinine and Na+ were assessed. Result of the analyses showed that the administration of the extracts did not significantly raise the serum activity of ALT. The decreases in serum concentrations of Urea and increase in the concentration of HCO3- were directly proportional to the concentration of the extracts. It can be deduced from this study, that 500mg, 1000mg 1500mg and 2000mg/kg bw of either C. papaya or P. biglobosa did not elicit any marked hepatotoxicological or renotoxicological effect on the experimental animals
