Date palm fruit (Phoenix dactylifera) is reputed to have numerous biological activities, including anticancer properties. To utilize the great fortune of this fruit, the current study aimed to maximize its pharmacological activity. Date palm extract (DPE) of Khalas cultivar was obtained in powder form and then was formulated into nanoemulsion (NE). The optimized DPE-NE was formulated along with its naked counterpart followed by studying their physical and chemical properties. A qualitative assessment of total serum protein associated with the surface of formulations was implemented. Studies for the in vitro release of DPE from developed NE before and after incubation with serum were investigated. Eventually, an MTT assay was conducted. Total phenolic and flavonoid contents were 22.89 ± 0.013 mg GAE/g of dry DPE and 9.90 ± 0.03 mg QE/g of dry DPE, respectively. Homogenous NE formulations were attained with appropriate particle size and viscosity that could be administered intravenously. The optimized PEGylated NE exhibited a proper particle size, PDI, and zeta potential. Total serum protein adsorbed on PEG-NE surface was significantly low. The release of the drug through in vitro study was effectively extended for 24 h. Ultimately; PEGylated NE of DPE attained significant inhibition for cancer cell viability with IC50 values of 18.6 ± 2.4 and 13.5 ± 1.8 µg/mL for MCF-7 and HepG2 cell lines, respectively. PEGylated NE of DPE of Khalas cultivar will open the gate for future adjuvants for cancer therapy.
Objectives Breast feeding is a normal behaviour in humans that provides babies with the nutrients needed for growth and development. Certain factors contribute to the inability of mothers to breastfeed. This investigation explored the effect of maternal occupation on breast feeding amongst females in Al-Hassa in the southeastern region of KSA. Methods This cross-sectional study was conducted by administering a structured Arabic questionnaire to working and non-working mothers in the region. The participants were asked about their job status and whether they were breast feeding (BF), the reasons for reducing or stopping BF, and the health status of their babies. The obtained data were analysed using the chi-square test. Results A total of 124 mothers participated in the survey; 62 working mother (WM) and 62 non-working women (NWM). All of the NWM had breastfed their babies, while ninety-two percent of the WM breastfed, while the remaining 8% (12.9) of WM did not breastfeed. The results also showed that only 7% of WM practiced exclusive breast feeding (EBF), while 37% of the NWM were found to practice EBF. Conclusions Maternal occupation was not observed to be a barrier to prevent mothers from breast feeding but affected the duration and frequency of breast feeding per day and the health status of babies.
Background:The aim of the study was to investigate the effects of dietary combination of Nigella sativa seed and oil extracts with chloroquine (CQ), and how these combinations enhance CQ efficacy in mice infected with Plasmodium berghei and their survival rates.Materials and Methods:Chloroquine sensitive P. berghei, NK65 strain was used for the study. This was passaged intraperitoneally into albino mice with a 0.2ml standard inoculum consisting of 106 parasitized erythrocyte suspension in phosphate buffer solution (PBS). Parasitaemia was ascertained by microscopical examination of blood films under oil immersion at X100 magnification.Results:Nigella sativa seed in feed (NSSF), NSSF + CQ on day 4, produced 86.1% and 86.0% suppression respectively, while Nigella sativa oil extract in feed (NSOF) and in combination with CQ had 86.0% and 99.9% suppression respectively. The degree of suppression with the combination was significantly higher compared to CQ alone (P < 0.001) (36.1%). Complete parasitaemia clearance was obtained on the 20th and 15th day of treatment for NSSF, NSSF + CQ respectively, while that for NSOF and NSOF + CQ was on days 26 and 12 respectively. For CQ parasite clearance was 12 days with treatment. Also, the combinastion of 10 mg/kg Nigella sativa oil treatment injected intraperitoneally with oral CQ produced very significant parasite suppression (P < 0.0001) (93%). Survival rate in NSSF and NSOF and in combination with CQ groups was 100 and 60.0% for CQ alone.Conclusions:This study shows that the use of Nigella sativa seed and oil extract as dietary supplements in combination with CQ has a potential in enhancing the efficacy of CQ and could be of benefit in management of malaria.
Diabetes mellitus (DM) is a complicated condition that is accompanied by a plethora of metabolic symptoms, including disturbed serum glucose and lipid profiles. Several herbs are reputed as traditional medicine to improve DM. The current study was designed to explore the chemical composition and possible ameliorative effects of Ocimum forskolei on blood glucose and lipid profile in high-fat diet/streptozotocin-induced diabetic rats and in 3T3-L1 cell lines as a first report of its bioactivity. Histopathological study of pancreatic and adipose tissues was performed in control and treatment groups, along with quantification of glucose and lipid profiles and the assessment of NF-κB, cleaved caspase-3, BAX, and BCL2 markers in rat pancreatic tissue. Glucose uptake, adipogenic markers, DGAT1, CEBP/α, and PPARγ levels were evaluated in the 3T3-L1 cell line. Hesperidin was isolated from total methanol extract (TME). TME and hesperidin significantly controlled the glucose and lipid profile in DM rats. Glibenclamide was used as a positive control. Histopathological assessment showed that TME and hesperidin averted necrosis and infiltration in pancreatic tissues, and led to a substantial improvement in the cellular structure of adipose tissue. TME and hesperidin distinctly diminished the mRNA and protein expression of NF-κB, cleaved caspase-3, and BAX, and increased BCL2 expression (reflecting its protective and antiapoptotic actions). Interestingly, TME and hesperidin reduced glucose uptake and oxidative lipid accumulation in the 3T3-L1 cell line. TME and hesperidin reduced DGAT1, CEBP/α, and PPARγ mRNA and protein expression in 3T3-L1 cells. Moreover, docking studies supported the results via deep interaction of hesperidin with the tested biomarkers. Taken together, the current study demonstrates Ocimum forskolei and hesperidin as possible candidates for treating diabetes mellitus.
