Rearrangement of Allyl Aryl Ethers III, Reactions of Alkoxyhydroquinones with Cycloalkenediols
(Elsevier, 1997)Cycloalkenobenzofurans were prepared in one-pot reaction from methoxyhydroquinone, 2,5- and 2,6 and 2,3- dialkoxyhydroquinone with cycloalkenediol. Reaction between isomeric 2,5- dialkoxyhydroquinone with diol led to the ... -
Preparation of Novel Cyanoguanidine Derivatives of Tryptamines
(Thieme, 2001)A new class of cyanoguanidine derivatives bearing a tryptamine moiety was prepared by a three-step reaction sequence. The preparation of the starting materials and characterization of the intermediates are also described. -
Rearrangement of Allyl Aryl Ethers II, Reactions of Hydroquinones with Cycloalkenediols
(Thieme, 1997)Cycloalkenobenzofurans are prepared in one operation from hydroquinone and cycloakenediol involving a sequence of acid-catalyzed formation of ether , 1,3- and 3,3-rearrangements, and acid-catalyzed intramolecular cyclization ... -

Association of cerebral palsy with consanguineous parents and other risk factors in a Palestinian population Print PDF version S. Daher1,2 and L. El-Khairy1,3
(WHO EMRO, 2014-12-07)ABSTRACT This case-control study investigated risk factors for cerebral palsy in a Palestinian population. Cases were 107 children aged 1-15 years at a cerebral palsy referral centre in Jerusalem; controls were 233 children ... -
Risk factors for cerebral palsy in Palestinian children: a case-control study Suzy Daher, MPH Lina El-Khairy, PhD
(Lamcet, 2013-12-05)Little is known about the risk factors for cerebral palsy in the occupied Palestinian territory (oPt). Indeed, the focus in studies so far has been on developed countries. We therefore assessed known prenatal and perinatal ... -
FORMULATION AND EVALUATION OF HERBAL SHAMPOO CONTAINING OLIVE LEAVES EXTRACT
(IJDR, 2018-10-29)The study aimed at formulating a herbal shampoo containing olive leaves extract and evaluating its physiochemical properties. Olive leaves extract in shampoo is commercially available in Palestine, but because the R&D ... -
Extraction Method and Evaluation of Phenolics, Flavonoids, Antioxidant activity, Antimicrobial Activity and Minerals of Bitter Lupinus albus in Palestine
(Taylor and Francis, 2018)In this paper, extraction methods for bitter Lupinus albus seeds are described. Samples were either soaked with water (thereafter soaked) or used without soaking (thereafter unsoaked) and were exposed to Soxhlet extraction ... -
Comparison of extraction yields, antioxidant, antimicrobial activity and concentration of main components of Olea europaea leaf samples at different seasons and of different areas of Palestine
(International Journal of PharmTech Research, 2018)Olea europaea is widely cultivated tree for oil production in the Mediterranean area. The benefits of olive leaves refer to their vital polyphenols components. In this study, the optimum way for the extraction of olive ... -
Cancer Immunotherapy with CAR-T cells for Hematological Malignancies
(Scientific & Academic Publishing, 2017-04)Cancer treatment for hematological malignancies traditionally included systemic chemotherapy and localized radiotherapy for central nervous system (CNS) disease. These therapies in addition to their adverse effects’ profile ... -
Planting the Seeds to Overcome Uprooting: A Study of the Forced Transformations in the Palestinian Peasant’s Life

Optimal designs for contingent response models with application to toxicity–efficacy studies
(Springer Science & Business Media, 2012)We describe a general family of contingent response models. These models have ternary outcomes constructed from two Bernoulli outcomes, where one outcome is only observed if the other outcome is positive. This family is ... -
A simulation study to assess a variable selection method for selecting single nucleotide polymorphisms associated with disease
(Mary Ann Liebert, Inc. 140 Huguenot Street, 3rd Floor New Rochelle, NY 10801 USA, 2012)In genome-wide association studies, where hundreds of thousands of single nucleotide polymorphisms (SNPs) are genotyped, the potential for false positives is high and methods for selecting models with only a few SNPs are ... -
Differential expression of BRCC2, a novel BH3-like domain-containing apoptotic molecule, in ductal versus lobular breast carcinoma
(American Association for Cancer Research, 2007)Background: BRCC2 (breast cancer cell 2) gene was discovered as an approximately 1.2 kb transcript in MDA-MB 231 human breast cancer cells (GenBank accession numbers AF220061 and AF303179). BRCC2 is a 12 kDa cytosolic ... -
Variation in shoot tolerance mechanisms not related to ion toxicity in barley
(CSIRO, 2017)Soil salinity can severely reduce crop growth and yield. Many studies have investigated salinity tolerance mechanisms in cereals using phenotypes that are relatively easy to measure. The majority of these studies measured ... -
Mapping of novel salt tolerance QTL in an Excalibur× Kukri doubled haploid wheat population
(Springer, 2017-07)Novel QTL for salinity tolerance traits have been detected using non-destructive and destructive phenotyping in bread wheat and were shown to be linked to improvements in yield in saline fields. Abstract Soil salinity ... -
A QTL on the short arm of wheat (Triticum aestivum L.) chromosome 3B affects the stability of grain weight in plants exposed to a brief heat shock early in grain filling
(BioMed Central, 2016)Background: Molecular markers and knowledge of traits associated with heat tolerance are likely to provide breeders with a more efficient means of selecting wheat varieties able to maintain grain size after heat waves during ... -
Heat susceptibility of grain filling in wheat (Triticum aestivum L.) linked with rapid chlorophyll loss during a 3-day heat treatment
(Springer, 2016)Brief heat events (1–3 days, >30 °C) commonly reduce wheat (Triticum aestivum L.) grain size and consequently yield. To identify mechanisms of tolerance to such short heat events, 36 wheat genotypes were treated under ... -
Variation for N uptake system in maize: genotypic response to N supply
(Frontiers, 2015)An understanding of the adaptations made by plants in their nitrogen (N) uptake systems in response to reduced N supply is important to the development of cereals with enhanced N uptake efficiency (NUpE). Twenty seven ... -
Accounting for variation in designing greenhouse experiments with special reference to greenhouses containing plants on conveyor systems
(BioMed Central, 2013)Background: There are a number of unresolved issues in the design of experiments in greenhouses. They include whether statistical designs should be used and, if so, which designs should be used. Also, are there thigmomorphogenic ...
