Some people do not like many foods, eat very quickly or slowly, or eat too much or too little. These problems are more common in children with autism or ADHD and may continue for a long time, but we do not know much about these problems in adults. Our goal was to understand how eating difficulties are similar and different in adults with autism, ADHD, both autism/ADHD, and neither condition.

Background: Streptococcus agalactiae (Group B streptococcus, GBS) induces a serious infection that can harm not only aquatic life but also humans and other animals. In a fish farm in southern Egypt, Nile tilapia (Oreochromis niloticus) has developed an epidemic with clinical symptoms resembling piscine streptococcosis.

Results: Initial microscopic inspection of the affected fish brain and kidney indicated the presence of Gram-positive cocci.

Article Synopsis
  • - This study assessed the effectiveness of bone anchored maxillary protraction (BAMP) in treating class III skeletal malocclusion in children (ages 11-14) compared to a control group receiving no treatment, focusing on surgery necessity, dental changes, and psychological effects.
  • - Conducted as a randomized controlled trial in six UK hospitals, 57 participants were divided into two groups: 28 received BAMP treatment, while 29 were in the no-treatment control group; measurements were taken at multiple points over 3 years.
  • - Results showed significant improvements in skeletal and dental measures for the BAMP group at the 18-month mark, with a lower percentage of participants in this group feeling they needed surgery at the 3-year

Disc displacement without reduction (DDwoR) can cause pain and limitations in mouth opening, with a significant impact on function. The optimal management strategy for DDwoR is unclear. Treatments include conservative management such as mandibular manipulation, occlusal splints, and patient education/self-management, as well as arthrocentesis, which is a minimally invasive procedure.

Land snails are a destructive agricultural pest in economic crops, but the populations for that pest are highly influenced by temperature and humidity, therefore climatic changes affected their behavior, distribution and population dynamics, for these reasons researchers should follow up on the changes in their behavior, distribution, and population dynamics. In this study, a survey study was conducted to define land snail species existing at Sharkia Governorate, Egypt, from January 2019 to March 2022 in horticultural, vegetable, and field crops and study the population dynamics for the dominant land snail species. Results showed that there are six species of land snails, these species were, Monacha cartusiana, Succinea putris, Eobania vermiculata, Theba pisana, Helicella vestalis, and Cochlicella acuta.

In this article, we investigate the links between medical practice and expertise, on the one hand, and nationalist discourses, on the other, in the 2011 Egyptian uprising and the years that followed, which witnessed a consolidation of authoritarianism. We ask how it is that doctors, whose social capital in part rests on their being seen as "apolitical," played a significant role in countering consecutive regimes' acts of violence and denial. We trace the trajectory of the doctors' mobilization in the 2011 uprising and beyond and demonstrate how the doctors drew on their professional expertise and nationalist sentiment in their struggles against a hypernationalistic military state.

As an attempt to contribute to the efforts of combating the pandemic virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) responsible for COVID-19, new analogs of the repurposed drug nitazoxanide which showed promising inhibitory efficacy on a viral protease enzyme were designed, synthesized and evaluated for their inhibitory activity on the main protease of the SARS-CoV-2 virus, using the COV2-3CL protease inhibition assay. The obtained results showed that the N-(substituted-thiazol-2-yl)cinnamamide analogs 19, 20, and 21 were the most active compounds with IC values of 22.61, 14.

Article Synopsis
  • - The review discusses the use of natural compounds, specifically coumarins, as potential antiviral agents against COVID-19 by focusing on virus spike proteins and their interactions with human receptors.
  • - Researchers filtered 74 various coumarin compounds based on ADME analysis and employed virtual screening techniques to assess their ability to inhibit key viral enzymes and proteins related to SARS-CoV-2.
  • - Promising findings indicate that certain natural coumarin compounds show potential effectiveness against viral targets like RNA-dependent RNA polymerase and methyltransferase, suggesting further investigation is warranted.

Background: Ketosis is one of the most critical metabolic disorders that occur in dairy cows after parturition due to negative energy balance around calving.

Aim: The study evaluated a specific therapeutic regimen of ketosis in Holstein dairy cattle by using the combination therapy including hormones, corticosteroids, propylene glycol, and vitamin B12 as well as the use of milk yield rates, insulin, insulin sensitivity, and abomasal functions monitors as diagnostic biomarkers for the recovery of ketotic cows either pre-therapy (0 days) or post-therapy (7 and 14 days).

Methods: This study was conducted on ketotic cattle ( = 20) belonged to different dairy farms in Cairo and Giza governorates, Egypt.

The trigeminocardiac reflex is a rare occurrence in patients undergoing maxillofacial surgery, with a reported incidence of 1-2%. Clinical signs and symptoms include bradycardia, nausea, with further stimulation potentially leading to cardiac dysrhythmias, ectopic beats, atrioventricular blocks and asystole. Most maxillofacial procedures, including temporomandibular joint procedures, are considered low risk.
