So, we assessed CELF4 (rs1786814) gene polymorphism on anthracycline-related cardiotoxicity in childhood cancer survivors (CCS).

Methods: This comparative cross-sectional study included 53 CCS who had regular follow-up visits at the Pediatric Oncology Unit, Menoufia University Hospital.

Uncovering an effecient binary system as a chemosensor for visual and fluorescence detection of chromium (VI) in water samples.

There is an urgent requirement for the development of sensitive and quick sensors to monitor chromium (VI) due to its substantial carcinogenic and mutagenic properties. A coexisting system of coumarin 334 and diphenylcarbazide (C334/DPC) was used in this study as a fluorescent chemosensor to detect Cr(VI) ions. Upon the addition of Cr(VI), a purple chelate complex (Cr(III)-diphenylcarbazone) was produced, which resulted from the quantitative reaction between Cr(VI) ions and diphenylcarbazide (DPC), whereas no interaction between Cr(VI) and coumarin 334 took place.

Environmental pollution is a major issue today due to the release of dyestuff waste into the environment through industrial wastewater. There is a need for affordable and effective adsorbents to remove harmful dyes from industrial waste. In this study, Mandarin biochar-CO-TETA (MBCOT) adsorbent was prepared and used to remove Acid Red 73 (AR73) dye from aqueous solutions.

Inter-Semispinalis Plane Block Versus General Anesthesia for Postoperative Analgesia in Posterior Cervical Spine Surgery: A Randomized Controlled Trial.

Background: Postoperative pain management is crucial for improving patient outcomes following posterior cervical spine surgery. Opioids are effective but carry a risk of respiratory depression. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used but may not provide adequate pain relief and have potential complications.

Using augmented reality in molecular case studies to enhance biomolecular structure-function explorations in undergraduate classrooms.

Molecular case studies (MCSs) are open educational resources that use a storytelling approach to engage students in biomolecular structure-function explorations, at the interface of biology and chemistry. Although MCSs are developed for a particular target audience with specific learning goals, they are suitable for implementation in multiple disciplinary course contexts. Detailed teaching notes included in the case study help instructors plan and prepare for their implementation in diverse contexts.

Fabrication of carbon black nanoparticles from green algae and sugarcane bagasse.

There are several industrial uses for carbon black (CB), an extremely fine powdered form of elemental carbon that is made up of coalesced particle aggregates and almost spherical colloidal particles. Most carbon black is produced from petroleum-derived feedstock, so there is a need to find an alternative method to produce CB, which relies on renewable resources such as algae and agricultural waste. A process involving hydrolysis, carbonization, and pyrolysis of green algae and sugarcane bagasse was developed, as the optimal hydrolysis conditions (16N sulfuric acid, 70 °C, 1 h, 1:30 g/ml GA or SC to sulfuric acid ratio), a hydrolysis ratio of 62% for SC and 85% for GA were achieved.

Sources of hydrocarbons and their risk assessment in seawater and sediment samples collected from the Nile Delta coast of the Mediterranean Sea.

The aim of this work is to examine the levels, distribution, bases, and hazards of n-alkanes (n-C9 to n-C20) and PAHs in the seawater and sediments around oil production locations in the whole delta region. The variations in the levels of PAHs and n-alkanes in seawater and sediment of the Nile delta coast of the Mediterranean were investigated using GC-MS/MS. The Σn-alkanes residues ranged between 12.

Optimization strategy of CoO nanoparticles in biomethane production from seaweeds and its potential role in direct electron transfer and reactive oxygen species formation.

In the present study, three process parameters optimization were assessed as controlling factors for the biogas and biomethane generation from brown algae Cystoceira myrica as the substrate using RSM for the first time. The biomass amount, CoONPs dosage, and digestion time were assessed and optimized by RSM using Box-Behnken design (BBD) to determine their optimum level. BET, FTIR, TGA, XRD, SEM, XPS, and TEM were applied to illustrate the CoONPs.

Transfusion of blood components in pediatric age groups: an evidence-based clinical practice guideline adapted for the use in Egypt using 'Adapted ADAPTE'.

Pediatric transfusion is a complex area of medicine covering a wide age range, from neonates to young adults. Compared to adult practice, there is a relative lack of high-quality research to inform evidence-based guidelines. We aimed to adapt the pre-existing high-quality practice guidelines for the transfusion of blood components in different pediatric age groups to be available for national use by general practitioners, pediatricians, and other health care professionals.

Serum brain-derived neurotrophic factor in relation to craving and duration of abstinence in patients with heroin dependence-A case-control study.

Background And Objectives: Addiction is a chronic disorder that comes with emotional and financial burdens. Several neurobiological factors were correlated to opiate-use disorder which is brain-derived neurotrophic factor (BDNF). BDNF has been found to be involved in long-term potentiation of synaptic strength, a mechanism that is thought to motivate both natural adaption mechanisms as well as the development of addictive behavior.

After being synthesized, the physicochemical features of this substance were accurately described. Several characterization techniques including UV-Vis spectroscopy, FTIR, XRD, XPS, EDX, SEM, TGA, DRS and BET were applied to study the prepared Ag-La-CaTiO photocatalyst.

Protective effect of Moringa oleifera leaf ethanolic extract against uranyl acetate-induced testicular dysfunction in rats.

Uranyl acetate (UA) is used in civilian and military applications, predisposing it to wide dispersion in ecosystems. Using high-performance liquid chromatography, gas chromatography-mass spectrometry, and 2,2-Diphenyl-1-picrylhydrazyl scavenging radical analysis, we confirmed that Moringa oleifera leaf ethanolic extract (MLEE) is rich in biologically active phytochemicals. Thus, this study aims to investigate the possible defensive effect of MLEE against UA-induced testicular dysfunction.

Role of Eruca sativa L. seeds in boosting the reproductive performance of male Japanese quails (Coturnix c. japonica).

Herein we attempt to shed light on the potential improving effect of Eruca sativa seeds (ESS) on the reproductive aspects of male Japanese quails. To accomplish this objective, two groups of quails were supplemented with ESS powder at doses of 5 and 10 g/kg feed from 7 days to 140 days of age, in addition to the control group, which did not receive treatment. Forty males were reared singly in cages to evaluate sperm characters and 32 males were raised with 64 females to evaluate fertility and sperm penetrability.

Combined Infraclavicular-Suprascapular Nerve Blocks Compared With Interscalene Block for Arthroscopic Rotator Cuff Repair: A Prospective, Randomized, Double-blind, and Comparative Clinical Trial.

Background: The gold standard postoperative analgesia protocol for arthroscopic rotator cuff repair procedures is the interscalene block (ISB), which prevents the significant consequences of phrenic nerve block associated with hemidiaphragmatic paralysis (HDP). The infraclavicular brachial plexus block (BPB) combined with the suprascapular nerve block (SSNB) had the same analgesic efficacy as the infraclavicular BPB alone, with no effect on respiration.

Objectives: Therefore, the study aimed to assess the HDP and analgesic efficacy of both approaches in controlling pain following arthroscopic rotator cuff repair surgeries.
