Objective: To evaluate curve correctability, complications, and rate of growth following treatment.

Background: Distraction-founded techniques such as traditionally growing rods or magnetically controlled growing rods are the almost globally accepted management patterns for early onset scoliosis. However, periodic lengthening operations are still needed.

Article Synopsis
  • Researchers recorded humpback whale songs in Hawaii and Colombia, finding repeated acoustic patterns during their singing sessions.
  • The analysis showed that whales display cycles of acoustic complexity, correlating with their diving behavior and varying sound production over different time periods.
  • These variations suggest that humpback whales adjust their singing to optimize sound transmission and spatial detection, balancing between tonal and frequency-modulated elements.

Several studies have shown the importance of using seaweed liquid extract (True-Algae-Max, TAM) as a fish feed additive, and fish-water conditioner. In addition, TAM has demonstrated significant growth improvement when used as a plant growth biostimulant. This study investigates whether seaweed liquid extract (TAM) can achieve good results in new experimental fields such as chromium remediation, plant germination, and live feed supplementation for marine invertebrate Copepod (Oithona nana).

Article Synopsis
  • - The study aimed to analyze the testicular morphology and histology of local pigeons at different maturation stages to gain insight into their reproductive health.
  • - Results showed that the testis retains an oval shape and exhibits size differences between the left and right sides, with significant histological changes occurring from pre-puberty (smaller with collapsed tubules) to post-puberty (larger, closely packed tubules with mature cells).
  • - The findings emphasize the importance of understanding testicular structure changes in pigeons to assess male reproductive system complexity and the role of sex hormones and various cell types in testicular function.

Background Watchful waiting and non-operative management of patients with complete clinical response to neoadjuvant treatment in locally advanced rectal cancers is an emerging practice now, especially in patients whose surgery would require permanent stoma. Methodology This is a retrospective study of patients presenting to the National Cancer Institute, Cairo University, Egypt from January 2005 to December 2019 with pathologically proven locally advanced rectal cancer who had a complete clinical response after neoadjuvant treatment. Patients who underwent surgery after achieving complete clinical response and patients who were kept under watchful waiting were compared in terms of overall survival (OS), disease-free survival (DFS), metastasis-free survival (MFS), and local recurrence-free survival (LRFS).

Background: The treatment of psoriasis has made considerable progress with biologicals, including tumor necrosis factor inhibitors, and recently, monoclonal antibodies inhibiting directly interleukin (IL) 17, IL-23, or both IL-12/23. Newer biologicals are directed to the interleukin pathway and appear to improve complete or near-complete clearance. The newer biologicals have also been shown to have an excellent safety profile.

In this work, the nonlinear optical (NLO) properties of CuO nanoparticles (CuO NPs) were studied experimentally using the pulsed laser ablation (PLA) technique. A nanosecond Nd: YAG laser was employed as the ablation excitation source to create CuO NPs in distilled water. Various CuO NPs samples were prepared at ablation periods of 20, 30, and 40 min.

  • This study evaluates the effectiveness and safety of a one-stage procedure called anterior sagittal sphincter saving anorectoplasty (ASSSARP) for repairing rectovestibular fistula (RVF) in children.
  • It reviews 41 cases from 2010 to 2019, detailing postoperative complications, hospital stays, and functional and cosmetic outcomes.
  • Findings suggest that ASSSARP has good results, with minimal complications and no need for additional surgeries, making it a preferable option compared to traditional three-stage repair methods.

Diisononyl phthalate (DiNP) has been associated with the development of allergies, asthma, and allergic airway inflammation. Through a complex interplay of signals and feedback mechanisms, the lungs communicate with the heart to ensure maintenance of homeostasis and supporting the body's metabolic demands. In the current study, we assessed the crosstalk between DiNP-induced asthma and cardiac cellular respiration, oxidative stress, apoptotic potential, and induction of oncogenic factors.

This study aimed to screen the bioactive components in Streptococcus equinus WC (SE-WC) and Limosilactobacillus reuteri GM (LR-GM) and estimate the therapeutic role in Ehrlich solid tumors (EST) mice model. Forty-four male albino EST mice were assigned into 7 groups and treated daily for 2 weeks, including the EST group, the EST mice that received SE-WC at a low or a high dose (0.5 ml *10 or 0.

  • This study focused on acute myocardial infarction complicated by cardiogenic shock (AMI-CS) in the Gulf region, addressing a lack of data by analyzing 1,513 patients from 2020 to 2022.
  • The incidence of AMI-CS was found to be 4.1%, with a high in-hospital mortality rate of 45.5%, and patients primarily presented with ST-elevation MI.
  • Key risk factors for increased hospital mortality included previous coronary artery bypass grafts, chronic kidney disease, and SCAI shock stages D and E, with a 12-month survival rate of 51.49%.*

This is a retrospective study exploring the demographics and the role of nasal septum deviation in acute invasive fungal rhinosinusitis (AIFS); and if this deviation contributes to the laterality predilection of this opportunistic infection. Fifty-six craniofacial CT scans were evaluated by two radiologists blinded to the clinical data and outcome for laterality of the disease; and nasal septal deviation (NSD). NSD was graded based on the measured septal angle of deviation into mild, moderate, and severe and furtherly classified into one of seven types based on Mladina's classification.

Water quality in land-based fish production can be controlled through either instantaneous water exchange or costly wastewater treatment followed by recirculation. Agricultural-aquaculture integration is an excellent alternative technique for reducing nutrient discharge levels, boosting profitability, and converting fish culture wastewater into valuable products. The current study employed a solar energy system to power two separate IMTA-aquaponics systems (Nutrient Film Technique, NFT, and Floating Raft Systems, FRS) for the cultivation of Nile tilapia, African catfish, thin-lipped grey mullet, freshwater crayfish, freshwater mussels, and a variety of vegetables.

  • * A total of 384 tilapia were divided into four groups, with one group receiving a basal diet with no supplementation and the others receiving increasing levels of alga nanoparticles (2, 4, and 6 g kg−1).
  • * Results showed that the group with the highest supplementation (6 g kg−1) exhibited the best growth metrics, hormone levels, and a notable increase in fry production compared to the control group, indicating the potential benefits of this dietary addition.

The current study aimed to assess the influence of dietary inclusion of cyanobacterium Arthrospira platensis NIOF17/003 as a dry material and as a free-lipid biomass (FL) on the growth performance, body composition, redox status, immune responses, and gene expression of whiteleg shrimp, Litopenaeus vannamei postlarvae. L. vannamei were fed five different supplemented diets; the first group was fed on an un-supplemented diet as a negative control group (C-N), the second group was fed on a commercial diet supplemented with 2% of A.

Background: Buffalo spermatozoa have a distinct membrane structure that makes them more vulnerable to cryopreservation, resulting in lower-quality post-thawed sperm. This decreases the success rate of artificial insemination in buffaloes. Understanding and addressing these specific vulnerabilities are essential for improving reproductive techniques in buffalo populations.

The hydroethanol (70%) extracts of three species (, , and ) were analyzed using LC-ESI-MS/MS. Forty-five metabolites were identified, including different flavonoids, coumarin, polyacetylenes, and alkaloids, which were the most abundant class. By applying Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) based on LC-ESI-MS/MS analysis, the three species were completely segregated from each other.
