The Palestinian Terrestrial Vertebrate Fauna Preserved at the Biology Exhibitions of the Universities of the Gaza Strip

The Gaza Strip (365 km2 ) of Palestine (27,000 km2 ) is home to a wealth of terrestrial vertebrate fauna. Some of these faunistic species find their ways to preservation at the local universities. Hence, the current study comes to document the Palestinian terrestrial vertebrate fauna acquired by the biology exhibitions (BEs) of Al-Azhar University, Islamic University of Gaza and Al-Aqsa University that are located at the Gaza City of the Gaza Strip. The amphibians, reptiles, birds and mammals preserved at BEs of the universities in question were surveyed and scientifically classified during a three-month period extending from January to March, 2012. The study showed that all BEs of local universities are underdeveloped, lacking attention and suffer from specimen scarcity and good preservation. The BE at Al-Azhar University is the best in the arrangement and preservation of bird specimens. A total number of 200 specimens belonging to 54 terrestrial vertebrate fauna species, 39 families and 17 orders was recorded at BEs. Reptiles constituted 40.7% of the total species recorded, followed by birds (38.9%), mammals (14.8%) and amphibians (5.6%). The Islamic University of Gaza was considered the best in terms of the number of preserved species (39.8%), followed by Al-Azhar University (36.3%) and Al-Aqsa University (23.9%). The Common Toad (Bufo viridis) was the most preserved among the amphibian species recorded. Squamata was the biggest reptilian order, comprising 20 species (8 lizards and 12 snakes), with the Syrian Black Snake (Coluber jugularis asianus) was the commonest. The Palestine Viper (Vipera palaestinae) is endemic to Palestine and most venomous and dangerous to human health. The Great White Pelican (Pelecanus onocrotalus) was the largest Palestinian bird preserved at BE of Al-Azhar University. The Egyptian Mongoose (Herpestes ichneumon) and the Common Badger (Meles meles) were the biggest mammalian specimens preserved, while the Palestine Mole-rat (Spalax leucodon ehrenbergi) was the only Palestine endemic species encountered among the preserved mammals. Finally, the improvement of BEs of local universities and the construction of a Central Museum of Natural History is highly recommended in order to change the Palestinians’ attitudes toward a sustainable ecological conservation in the Gaza Strip

Value of lung ultrasound in detection of volume overload in children chronic kidney disease on regular hemodialysis: prospective cohort study

Abstract Background Several methods have emerged to predict the occurrence of early volume overload (VO) in pediatric patients with chronic kidney disease undergoing regular hemodialysis (HD). Nevertheless, achieving an accurate assessment remains challenging. Consequently, this study aimed to identify VO in pediatric HD patients using lung ultrasound (LUS). Additionally, the study sought to investigate the relationship between various clinical parameters employed to detect VO and the ultrasonographic B-line score. Methods This prospective observational cohort study was conducted on 30 pediatric patients with end-stage renal disease undergoing a maintenance HD program for 4 months. The clinical evaluation of the fluid status of pediatric patients involved using LUS pre-, intra, and post-HD. The study included the dry weight (DW) and non-DW groups; within these groups, the B-line scores were evaluated pre-, intra, and post-HD sessions. Tabulations were conducted to document the variations in body weight and B-line scores during pre-, intra-, and post-dialytic periods. Results The results of the LUSs performed on the 30 pediatric patients pre-, intra, and post-HD revealed that the B-line scores significantly reduced post-HD in all pediatric patients with more significant reduction in non-dry weight group (p < 0.001). There was a positive relation between the total number of B-lines pre-HD and inter-dialytic weight gain, pre-dialytic blood pressure, and clinical fluid score (r = 0.811, p < 0.01; r = 0.59, p < 0.001; and r = 0.75, p < 0.001, respectively) and also post-dialysis. Eventually, dialytic weight loss exhibited a significant direct positive correlation to B-line score reduction (r = 0.891, p < 0.01). Conclusions LUS is an innovative, simple noninvasive bedside method that provides real-time evaluation of fluid volume alterations in pediatric HD patients with chronic conditions. LUS shows excellent potential as a viable approach for assessing DW and non-dry weight in pediatric HD patients

Investigations into structure-property relationships of novel Ru(II) dyes with N,N?-Diethyl group in ancillary ligand for dye-sensitized solar cells

Structure-property relationships of four novel bipyridyl Ru(II) complexes, denoted as SD-22, SD-24, SD-26 and SD-28, are reported herein. The molecular structures of all four photosensitizers were confirmed using FT-IR, 1H NMR and mass spectrometry. Photovoltaic characteristics of the photosensitizers were evaluated under 1.5 a.m. standard illumination condition, in presence of deoxycholic acid as co-adsorbent, and subsequently compared to the performance of the benchmark, Z907. SD-22 showed an IPCE of 52% and 50% at 440 nm and 550 nm, respectively, a short-circuit photocurrent density (JSC) of 17.37 mA cm−2, open-circuit photovoltage (VOC) of 0.63 V and fill factor (FF) of 0.66, producing an overall conversion efficiency (η) of 7.31%, which outperformed Z907 (7.02%) under the same experimental device conditions. The η of the other photosensitizers is in the following order: SD-22 > SD-28 > SD-26 > SD-24. Photosensitizer SD-22 has N,N′-dialkyl group attached to a benzene ring while SD-24 has N,N′-dialkyl without a benzene ring. The extended conjugation in SD-22 translated into higher overall solar-to-electric conversion efficiency. Substitution of dialkylamino-based ancillary ligands of Ru(II) dyes SD-26 and SD-28 with –OCH3 and –OC6H13 also demonstrated that the photovoltaic performance of polypyridyl ruthenium photosensitizers is a function of the donating power of ancillary ligands as well as the steric effect of alkoxy auxochromes at –ortho position.The authors would like to thank the Higher Education Commission, Pakistan , Pakistan for financial assistance of this project.

الأشجار والشجيرات المتزاجدة في الحرم الرئيس للجامعة الإسلامية بغزة، قطاع غزة، فلسطين

The Gaza Strip, which has a population of about 2.0 million and an area of about 365 km2, has many higher education institutions. The green quadrates, corridors and gardens of these institutions are commonly cultivated with many horticultural plants including trees and shrubs that provide many environmental, health, and aesthetic values. The Palestinian universities of the Gaza Strip have never been studied for the composition and numbers of their trees and shrubs. Therefore, the current study aims at identifying and recording the trees and shrubs prevailing and enhancing the ecology and environmental health aspects of the main campus of the Islamic University of Gaza (MC-IUG). Frequent surveys and observations were carried out during a six-month study extended from February, 2018 to July, 2018 in order to identify and totally count the trees and shrubs existing at MC-IUG. A total number of 2248 trees and shrubs belonging to 53 species, 25 families and 16 orders were identified and recorded at the MC-IUG. The Gymnosperms included 5 species (9.43%) only, while the Angiosperms was represented by 48 species (90.57%), of which the monocots were 9 species (16.98%) and the dicots were 39 species (73.59%). Rosales was the biggest order and comprised 9 (16.98%) of the recorded species. It was followed by Lamiales and Myrtales which comprised 5 (9.43%) for each. The orders Pinales, Arecales, Asparagales and Malpighiales were represented by 4 species (7.55%) for each. Moraceae was the biggest family and comprised 8 (15.09%) of the recorded species. It was followed by the two families Arecaceae and Asparagaceae, which comprised 5 species (9.43% for each). Six tree and shrub species (11.32%) of MC-IUG were found to exceed the threshold of 100 individuals for each. These comprised 1657 individuals (73.71%) of the 2248 counted. The Chinese Hibiscus (Hibiscus rosa-sinensis) was, by far, the most common species. It comprised 31.98% of the individuals counted. This was followed by the Benjamin Fig (Ficus benjamina) (10.45%), Hopbush (Dodonea viscose) and Moringa (Moringa oleifera) (8.63% for each), Dwarf Umbrella Tree (Schefflera arboricola) (8.19%) and Weeping Fig (Ficus nitida) (5.82%). The majority of tree and shrub species 49 (92.45%) recoded in the current study are exotic, while the native ones are restricted to only 4 species (7.55%). Finally, the current study recommends the selection of tree and shrub species corresponding with the local prevailing environmental conditions in order to ensure the ecological and environmental health values needed by the university community.The Gaza Strip, which has a population of about 2.0 million and an area of about 365 km2, has many higher education institutions.
