Abstract
This study explores the antioxidant activity, phytochemical screening, total phenolic and flavonoids contents in the extracts of four locally available weeds plants namely Convolvulus arvensis, Chenopodium murale, Avena fatua and Phalaris minor with different solvents. The antioxidant activities of these extracts were determined via various in-vitro methods such as total antioxidant activity (TAA), reducing power (RP), DPPH (2,2-Diphenyl-1-Picrylhydrazyl) free radical scavenging and hydrogen peroxide scavenging assays. Phytochemical screening was performed both qualitatively as well as quantitatively. Total phenolic content (TPC) and total flavonoid content (TFC) were determined through Folin- Ciocalteu reagent and aluminium chloride methods respectively. Methanol-chloroform solvent showed the presence of a high amount of TPC in milligram of gallic acid equivalent per gram of dry weight (mg of GAE/g of DW) in the extracts of all weeds. Their descending sequence was Avena fatua (74.09) ˃ Phalaris minor (65.66) ˃ Chenopodium murale (64.04) ˃ Convolvulus arvensis (61.905), while, chloroform solvent found to be best solvent for the extraction of TFC. Methanol-chloroform solvent was also found to be best solvent for TAA (Total antioxidant activity assay) which showed values in milligram of ascorbic acid equivalent per gram of dry weight (mg of AAE /g of DW), for DPPH scavenging activity, reducing power (antioxidant activity) and hydrogen peroxide scavenging activity. Phytochemical screening indicated the presence of polyphenols, flavonoids, tannins, saponins, alkaloids and glycosides in these weeds.

Abstract
BACKGROUND Vitamin D deficiency has been associated with an increased risk of falls in older adults. Several studies have demonstrated an association between vitamin D deficiency and gait and cognitive impairments, which are two risk factors for falls in the elderly. There is lack of research about the role of vitamin D in cognitive function in the context of mobility. OBJECTIVE The purpose of this study was to evaluate the association between vitamin D status with the age-related changes in mobility through higher order cognitive function using a dual task physical performance test. DESIGN Cross-sectional. SETTING Community-dwelling older adult population located in Miami, Fl. PARTICIPANTS Healthy participants over the age of 55 (n=97) who participated in the parent interventional study. MEASUREMENTS Participants completed assessments that included serum levels of vitamin D, surveys, and dual task physical performance tests. Spearman's correlations, independent t-tests, repeated measures ANOVAs and multiple logistic regressions were used to examine the relationship between vitamin D insufficiency (25-hydroxyvitamin D <30 ng/ml) and sufficiency (≥30 ng/ml) and dual task physical performance variables. The significance level was set at α=0.05. RESULTS There were no significant associations between vitamin D insufficiency and gait velocity during either task. Using Spearman correlations, slower single (P=0.011) and dual task counting rates (P=0.006) were significantly associated with vitamin D insufficiency. Independent t-tests showed dual and single task counting rates were significantly lower in the vitamin D insufficient group compared to the sufficient group (P=0.018 and P=0.028, respectively). The results for the ANOVAs indicated that velocities and counting rates were not significantly different by vitamin D status (Wilk's Lambda =0.999; F (1, 95) =.11, P=.740) (Wilk's Lambda =.999, F(1,95)=.13, P=.718). Vitamin D status was not significantly associated with dual task physical performance (defined as the difference in dual and single task) in gait velocity (OR=1.00, 95% CI: 0.98; 1.02, P=0.772) and counting rate (OR=1.684, 95% CI: 0.15; 19.57, P=0.677), when controlling for confounders. CONCLUSIONS Since counting backward is a mental tracking task, which is a component of executive function, our results suggest a relationship between vitamin D insufficiency and executive dysfunction. Executive dysfunction has been previously associated with fall risks in the elderly, and it could be a possible mediator between vitamin D and falls. Our data suggest that cognition may play a significant role in vitamin D's influence on falls, while motor function may play a lesser role.

Abstract
STUDY DESIGN This is a cross-sectional questionnaire. OBJECTIVES The objective of this study was to describe the impact of parenting young children with a spinal cord injury (SCI) on various life situations (for example, personal, vocational and social). SETTING Community; Denmark. METHODS A postal survey was designed to collect data in persons with SCI regarding the following: (1) socio-demographics, injury characteristics and parental status; (2) employment status; (3) environmental adjustments to support parenting roles; (4) childcare institution use and experiences; (5) network support for parenting; and (6) parenting advice for others. RESULTS A total of 62 persons (58% men) responded to the survey, with 56% having paraplegia and 44% having tetraplegia. The majority of men (83%) and women (62%) were employed during the first 10 years of their child's lives. Half of the sample (50%) did not find the accessibility of their childcare institutions optimal to accommodate their SCI. Only 22% felt that they got answers about being a parent with an SCI. The main advice provided by the sample to those considering of becoming a parent was encouragement, whereas the advice for municipalities was to provide more funding support for personal assistance and aids. CONCLUSION The present study provides insights into the challenges and satisfaction of being a parent post SCI across various life domains. Overall, the sample was very satisfied with their parenting role. The major issue noted for parents with SCI was the lack of support from local municipalities.

Abstract
BACKGROUND The present study was designed to detect the presence of tick-borne parasites (Theileria and Babesia spp.) in 196 blood samples collected from apparently healthy sheep and goats from two provinces, Punjab and Khyber Pukhtoon Khwa, in Pakistan. METHODS Reverse line blot (RLB) assay was applied for the parasitic detection by the amplification of hypervariable V4 region of the 18S ribosomal RNA (rRNA) gene. A membrane with covalently linked generic and species specific oligonucleotide probes was used for the hybridization of amplified PCR products. RESULTS Parasites were detected in 16% of the ruminant blood samples under study. Two Theileria species, T. lestoquardi and T. ovis, were identified in samples. 25, of the total 32, infected animals were from Khyber Pukhtoon Khwa. CONCLUSION Sheep were more prone to tick borne haemoprotozans as 81% infected samples were sheep as compared to 19% goats (P > 0.001). Risk factor analysis revealed that male (P = 0.03), animals infested by ticks (P = 0.03) and herd composed of sheep only (P = 0.001) were more infected by blood parasites.
