Article Abstract
Stroke is one of the major reasons of death in the United States and related to adult disability. Despite aggressive research, the treatment approaches of stroke still remains a major clinical problem. Intravenous immunoglobulin (IVIg) is a polyspecific Ig G preparation obtained from plasma of several thousand healthy people (donors). IVIg is an important treatment approach and used for several disorders. The aim of this study was to investigate the potentially beneficial effects of IVIg therapy in experimentally induced ischemia in middle cerebral artery occlusion (MCAo) models of rats. A total of 30 adult male Sprague Dawley rats were used. The rats were divided into two equal groups, each consisting of 15 randomly selected rats: control group (n = 15) and IVIg group (n = 15). Intraluminal filament method was used for establishment of cerebral ischemia. Intraluminal filament was withdrawn after 2 h of MCAo and reperfusion started again and passed to therapeutic stages for all the groups. Physiologic saline solution of 0.5 ml/kg was administered to the control group and 400 mg/kg IVIg was given to the IVIg group rats intravenously. In neurological evaluation, the worst score was determined as 3 and the best score as 0. After routine process, the brain tissue was prepared histopathological investigation. The IVIg group showed significantly better recovery with respect to the control group by neurological examination. The observation of specimens obtained from IVIg groups showed that findings correlate with grade 1 and -2 histopathologically. Nevertheless, ischemic amendments were observed to comply with grade 3 in ischemic areas in control group. IVIg therapy can be used in the treatment of ischemic stroke patients.

Background: Disruptive behavior and emotional problems - especially anxiety - are common in children and frequently co-occur. However, the role of co-occurring emotional problems in disruptive behavior intervention response is unclear. This study aimed to compare the effectiveness of an indicated prevention program in children with disruptive behavior problems with vs.

Background: Although current evidence supports the effectiveness of social norm feedback (SNF) interventions, their sustained integration into primary care remains limited. Drawing on the elements of the antimicrobial SNF intervention strategy identified through the Delphi-based evidence applicability evaluation, this study aims to explore the barriers and facilitators to its implementation in primary care institutions, thereby informing future optimization.
Methods: Based on the five domains of the Consolidated Framework for Implementation Research (CFIR), we developed semi-structured interview and focus group discussion guides.

Background: Disturbances in lipid metabolism are usually associated with hyperlipidemia, which is commonly observed in donkeys with inappetence or anorexia. The diagnostic utility of ultrasound measurements of croup fat thickness (CFT) and relative liver echogenicity for lipomobilization in donkeys with fasting-induced hyperlipidemia was investigated. A prospective observational control study involving 25 donkeys was conducted, and the animals were randomly assigned to a fasting group (FG, n = 20) and a control group (CG, n = 5).

We study the dynamics of coexisting influenza and SARS-CoV-2 by adapting a well-established age-specific COVID-19 model to a multi-pathogen framework. Sensitivity analysis and adjustment of the model to real-world data are used to investigate the influence of age-related factors on disease dynamics. Our findings underscore the critical role that transmission rates play in shaping the spread of influenza and COVID-19.

Background: This study aimed to evaluate the impact of asthma severity on biventricular cardiac functions using tissue Doppler imaging (TDI), two-dimensional speckle tracking echocardiography (2D-STE), and three-dimensional speckle tracking echocardiography (3D-STE).
Methods: Sixty-three children with asthma, aged between 5 and 16 years, were enrolled in the study along with 63 matched controls. All participants underwent cardiac assessments, including TDI, 2D-STE, 3D-STE, conventional echocardiography, and pulmonary function testing with spirometry.
