Synthesis and anti-Aphid Aphis gossypii (Glover) activity of some new quinoline derivatives
A series of quinoline derivatives have been elaborated fromreaction of 2-(m- and p-acetylanilino)-quinolines 6a-b withaldehydes under Claisen-Schmidt conditions followed by cyclization with phenyl hydrazine and hydroxylamine. Reaction of  6a and 6b with hydrazine, semicarbazide and thiosemicarbazide, cyanoacetylhydrazide and subsequent some condensation reactions led to diverse quinoline derivatives. Anti aphid  Aphis gossypii that harm cotton cropin Egypt was screened. Compound  12 showed an LC50 value of 19429E-10 ppm which is very more active than Marshal (Carbosulfan), one of the broad spectrum insecticides widely used in this field
The Effect of two Schedules of Intermittent Enteral Feeding on the Development of Gastric Colonization
Nutritional support is an important aspect of the care of traumatized patients and it can result in improving wound healing, decreasing catabolic response to injury, enhancing immune system function, improving gastrointestinal structure and function, and improving clinical outcomes. However, many complications are associated with enteral feeding including gastric colonization. Routine enteral feeding schedule is not allowing time to acidify stomach with gastric pH. This may predispose the traumatized patients to acquire gastric colonization which may predispose to aspiration pneumonia. Aim: this study was carried out to investigate the effect of two schedules of intermittent enteral feeding on the development of gastric colonization Design: a quasi-experimental design. Setting: trauma ICU at Assiut University Hospitals, Egypt. Patients: A convenience sample of 80 adults' traumatized patients on enteral feeding constituted the study sample. The patients were assigned into two equal groups (group 1 and group 2, 40 patients each). Methods: The only manipulation was in the rest period and time interval in which the group 1 patients were rested 8hours at night as compared to 6hours for the group 2 ones, as well group 1 patients were having 4hours time interval between each two consecutive feeding as compared to 2hours for group 2 patients. Results: ninety percent of group 2 patients developed gastric colonization as compared to 40% of the group 1 patients with a highly significant statistical difference between both groups in this regard (p= 0.000).Conclusion: intermittent 4-hour interval enteral feeding schedule inhibit the development of gastric colonization. Keywords: intermittent enteral feeding, gastric colonization

Synergistic Effect of Sophora japonica and Glycyrrhiza glabra Flavonoid-Rich Fractions on Wound Healing: In Vivo and Molecular Docking Studies.
Peer reviewed: TrueGlycyrrhiza glabra and Sophora japonica (Fabaceae) are well-known medicinal plants with valuable secondary metabolites and pharmacological properties. The flavonoid-rich fractions of G. glabra roots and S. japonica leaves were prepared using Diaion column chromatography, and the confirmation of flavonoid richness was confirmed using UPLC-ESI-MS profiling and total phenolics and flavonoids assays. UPLC-ESI-MS profiling of the flavonoid-rich fraction of G. glabra roots and S. japonica leaves resulted in the tentative identification of 32 and 23 compounds, respectively. Additionally, the wound healing potential of topical preparations of each fraction, individually and in combination (1:1) ointment and gel preparations, were investigated in vivo, supported by histopathological examinations and biomarker evaluations, as well as molecular docking studies for the major constituents. The topical application of G. glabra ointment and gel, S. japonica ointment and gel and combination preparations significantly increase the wound healing rate and the reduction of oxidative stress in the wound area via MDA reduction and the elevation of reduced GSH and SOD levels as compared to the wound and Nolaver®-treated groups. The molecular docking study revealed that that major compounds in G. glabra and S. japonica can efficiently bind to the active sites of three proteins related to wound healing: glycogen synthase kinase 3-β (GSK3-β), matrix metalloproteinases-8 (MMP-8) and nitric oxide synthase (iNOS). Consequently, G. glabra roots and S. japonica leaves may be a rich source of bioactive metabolites with antioxidant, anti-inflammatory and wound healing properties

Higher Risks of Toxicity and Incomplete Recovery in 13- to 17-Year-Old Females after Marrow Donation: RDSafe Peds Results.
Although donation of bone marrow (BM) or peripheral blood stem cells (PBSCs) from children to family members undergoing allogeneic transplantation are well-established procedures, studies detailing levels of pain, symptoms, and long-term recovery are lacking. To address this lack, we prospectively enrolled 294 donors age <18 years at 25 pediatric transplantation centers in North America, assessing them predonation, peridonation, and at 1 month, 6 months, and 1 year postdonation. We noted that 71% of children reported pain and 59% reported other symptoms peridonation, with resolution to 14% and 12% at 1 month postdonation. Both older age (age 13 to 17 years versus younger) and female sex were associated with higher levels of pain peridonation, with the highest rates in older females (57% with grade 2-4 pain and 17% with grade 3-4 pain). Multivariate analyses showed a 4-fold increase in risk for older females compared with males age <13 years (P <.001). At 1 year, 11% of 13- to 17-year-old females reported grade 2-4 pain, compared with 3% of males age 13 to 17 years, 0% of females age <13 years, and 1% of males age <13 years (P = .01). Males and females age 13 to 17 years failed to return to predonation pain levels at 1 year 22% and 23% of the time, respectively, compared with 3% and 10% in males and females age <13 years (P = .002). Our data show that females age 13 to 17 years are at increased risk of grade 2-4 pain at 1 year and >20% of females and males age 13 to 17 years do not return to baseline pain levels by 1 year after BM donation. Studies aimed at decreasing symptoms and improving recovery in older children are warranted
