Maximizing hydrocarbon recovery from mature and complex reservoirs is constrained by heterogeneity, sand production, and harsh operational conditions. While polyacrylamide (PAM)-based systems are pivotal in addressing these challenges, a comprehensive synthesis of their transformative evolution and multifunctional capabilities remains overdue. This review critically analyzes advancements in PAM-based materials for enhanced oil recovery (EOR), conformance control, and sand management.

BackgroundRespiratory distress (RD) is a major cause of admission to neonatal intensive care units (NICUs), highlighting the need for prompt and accurate assessment. Lung ultrasound (LUS) has emerged as a rapid, non-invasive, radiation-free tool with superior sensitivity to chest X-ray. Thoracic Fluid Content (TFC), measured via electrical cardiometry, may serve as a complementary parameter by reflecting pulmonary fluid load.

Background: Micafungin, Amphotericin B, and Fluconazole are the primary therapeutic agents employed to address invasive fungal candidiasis in neonates. Resistance to fluconazole is gradually developing in neonatal intensive care units. We aimed to conduct a comparative analysis of Micafungin and Amphotericin B in terms of their effectiveness and safety in the treatment of invasive fungal infections in neonates.

Accurate denoising of Electrocardiogram (ECG) signals is essential for reliable cardiac diagnostics, but traditional methods often struggle with high-frequency noise and artifacts, leading to potential misinterpretations. It is often impeded by interference such as power line interference (PLI) and Gaussian noise. To address this challenge, we suggest a novel ECG denoising technique that combines empirical mode decomposition (EMD) with wavelet domain sparse code shrinking.

Background: As one of the most common non-communicable diseases in Africa, Stroke ought to be dealt with properly with intensifying efforts to control its burden and to face obstacles in its management.

Methods And Results: In this follow-up study we reanalyzed stroke services and related obstacles in 17 African countries that were previously studied in 2021/22 in aspects related to manpower, acute stroke services, rehabilitation programs, number of stroke units/centers, telestroke services, awareness campaigns, and national and international stroke registries through a survey that was sent to stroke specialists and national stroke societies. Overall, there is an improvement in many fields yet many obstacles in the implementation of telestroke services, acute management, secondary prevention, post-discharge services, and follow-ups whether governmental, medical, or societal are prevalent.

HIV disease is recognized to cause inconsistencies in coagulation via various pathways during infection. Some studies have indicated that HIV-infected patients are prone to developing thrombocytopenia, thrombosis, or autoantibodies that may cause difficulties in diagnosis. This study is intended to measure the trend of coagulation parameters in Sudanese patients with HIV.

The coronavirus has become the most interesting virus for scientists because of the recently emerging deadly SARS-CoV-2. This study aimed to understand the behavior of SARS-CoV-2 through the comparative genomic analysis with the closest one among the seven species of coronavirus that infect humans. The genomes of coronavirus species that infect humans were retrieved from NCBI, and then subjected to comparative genomic analysis using different bioinformatics tools.

Article Synopsis
  • The study aimed to compare the effectiveness of BioHPP as a substructure in a hybrid prosthesis against a BioHPP bar supporting an implant overdenture, focusing on bone height changes and patient satisfaction.
  • Fourteen fully edentulous male patients received implants and either a BioHPP hybrid prosthesis or a BioHPP bar overdenture, with bone loss monitored over 18 months and patient satisfaction evaluated through a visual analog scale questionnaire.
  • Results indicated that the BioHPP hybrid prosthesis experienced greater marginal bone loss compared to the bar overdenture, but patient satisfaction was similar overall, with the overdenture group feeling slightly less comfortable.

The gene encodes a protein that is essential for the immune system. This gene is important in organ transplant rejection and acceptance, as well as multiple sclerosis, systemic lupus erythematosus, Addison's disease, rheumatoid arthritis, caries susceptibility, and Aspirin-exacerbated respiratory disease. The following variants were investigated: single-nucleotide variants (SNVs), multi-nucleotide variants (MNVs), and small insertions-deletions (Indels) in the gene via coding and untranslated regions.

: HLA-DRB1 is the most polymorphic gene in the human leukocyte antigen (HLA) class II, and exon 2 is critical because it encodes antigen-binding sites. This study aimed to detect functional or marker genetic variants of HLA-DRB1 exon 2 in renal transplant recipients (acceptance and rejection) using Sanger sequencing. : This hospital-based case-control study collected samples from two hospitals over seven months.

Palm kernel meal (PKM) has been shown to be a high-quality protein source in ruminant feeds. This study focused on the effects of feed, supplemented with different amounts of PKM (ZL-0 as blank group, and ZL-15, ZL-18, and ZL-21 as treatment group), on the quality and flavor profile of Tibetan sheep meat. Furthermore, the deposition of beneficial metabolites in Tibetan sheep and the composition of rumen microorganisms on underlying regulatory mechanisms of meat quality were studied based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry as well as 16S rDNA sequencing.

The effectiveness of antibiotics that save millions of lives is in danger due to the increasing rise of resistant bacteria around the world. We proposed chitosan-copper ions (CSNP-Cu) and chitosan-cobalt ion nanoparticles (CSNP-Co) as biodegradable nanoparticles loaded with metal ions synthesized an ionic gelation method for treatment of antibiotic resistant bacteria. The nanoparticles were characterized using TEM, FT-IR, zeta potential and ICP-OES.

Background: Because humans lack α-galactosidase, foods containing certain oligosaccharides from the raffinose family, such as soybeans and other legumes, may disrupt digestion and cause flatulence.

Results: Aspergillus niger NRC114 α-galactosidase was purified using protein precipitation, gel filtration, and ion exchange chromatography steps, which resulted in a 123-fold purification. The purified enzyme was found to be 64 kDa using the SDS-PAGE approach.
