Phytochemical and antimicrobial screening of the crude extracts from the root, stem bark and leaves of Vitellaria paradoxa (GAERTN. F)

The root, stem and leaves of Vitellaria paradoxa, belonging to the Sapotaceae family and which have some ethnomedicinal applications were studied. Phytochemical screening of the plant parts reveals thepresence of carbohydrates (free reducing sugars, ketoses, pentoses and starch), saponins, steroids, tannins and alkaloids. The antimicrobial screening of the crude methanol extract carried out in vitro onthe following clinical isolates; Bacillus cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pnuemoniae and Salmonella typhi showed that the crude methanol extracts hadwider range of activity on these organisms than the petroleum ether extracts. The crude stem extracts inhibited the growth of P. aeruginosa, K. pneumoniae, B. cereus and S. typhi at concentration of 50mg/ml while the leaf had a minimal inhibition concentration (MIC) of 70 mg/ml on S. aureus, E. coli and S. typhi. The root had an MIC of 60 mg/ml on S. aureus, E. coli, P. aeruginosa, K. pneumoniae and S.typhi. The MBC in all the cases were slightly higher than the MIC and was lowest in the stem extracts which indicates that the stem bark may contain the most active components

Effects of an eight-week stepladder exercise protocol on lower limb muscular strength of apparently healthy young adults

Purpose. backward descent of stairs is associated with improved muscle strength and reduced joint stress, but the effect of backward ascent of stairs on lower limb muscle strength has not been reported. This study compared the effects of forward and backward stair climbing on lower limb muscle strength in apparently healthy young adults. Methods. The total of 31 young volunteers were allocated to either forward or backward stair climbing group (n = 16 and 15, respectively). Dynamic quadriceps and hamstring muscle strength was assessed in addition to thigh girth at baseline and at weeks 4 and 8 with the use of the repetitive maximum method and tape measure, respectively. Results. Between baseline and week 8, muscular strength in both groups (quadriceps: 14.4 ± 3.6 to 16.4 ± 3.4 kg; 14.0 ± 2.9 to 15.3 ± 2.7 kg; hamstring: 12.2 ± 3.2 to 13.4 ± 3.2; 11.7 ± 2.5 to 12.9 ± 2.7 kg) increased significantly (p0.05). The groups were comparable in all three measures post intervention. Conclusions. Forward and backward stair climbing protocols are effective for improving the dynamic strength of the hamstring and quadriceps muscles of apparently healthy young adults. Thus, either protocol could be used for the improvement of lower limbs dynamic muscle strength

Manpower capacity and reasons for staff shortage in primary health care maternity centres in Nigeria: A mixed-methods study

The heart-breaking maternal and neonatal health indicators in Nigeria are not improving despite previous interventions, such as ‘Health for all’ and ‘Millennium Development Goals. The unattained health-related goals/targets of previous interventions put the success of the new Sustainable Development Goals in doubt if the existing paradigm remains unchanged. Thus, mere branding of health policies without improving what constitutes the health system such as manpower capacity and quality as well as staff-patients ratio will be wasteful efforts. This issue of global public health concern provided an indication for describing the capacity of manpower and reasons for staff shortage in primary level of health that are providing maternity services to women and their new-borns in Nigeria

Effect of NPK fertilizer on the seedlings of Dialium guineense (Wild) and proximate analysis of the fruit

The study was carried out to determine the effect of NPK fertilizer at different levels on the growth of the seedlings of Dialium guineense. The proximate analysis and mineral composition evaluation were carried out on its fruit in order to reveal the nutrients and minerals in the species. Procured seeds were raised and forty eight relatively uniform seedlings were selected and transplanted into polypots containing sieved topsoil. NPK fertilizers at various levels (0g, 1g, 2g and 3g) were applied. The parameters assessed height, girth and leaf number. It was discovered that 2g produced tallest seedlings with average height 10.44cm while control had the shortest seedlings with height 8.43cm. 3g had the seedlings with highest number of leaves in the 1st week of assessment with an average of 7 leaves while 2g had the lowest with an average of 4 leaves. Though there was increase in girth throughout the weeks of assessment, there was no significant difference in the mean girth of all the treatments. So, for healthy nursery stock with considerable height necessary for competition on the field, 2g of NPK fertilizer is recommended for nursery managers. The mineral composition evaluation revealed that Potassium was present at 1.32% while Zinc was absent in the fruit. Proximate analysis of the fruit showed that it contains protein (1.4%), fat (3.21%), ash (2.5%), fibre (3.35%) and moisture content (4.8%). this exposed the nutritional value that could be explored by food and fruit processing industriesKey words: Dialium guineense, proximate analysis, fertilizer, mineral composition evaluatio
