Chronic inflammatory bowel disorders (IBDs) are characterized by altered intestinal permeability, prompting inflammatory, oxidative stress, and immunological factors. Gut microbiota disorders impact brain function via the bidirectional gut-brain axis, influencing behavior through inflammatory cascades, oxidative stress, and neurotransmitter levels. This study highlights the potential effect of integrating lyophilized milk kefir alone and lyophilized milk kefir as solid carriers loaded with a self-nanoemulsifying self-nanosuspension (SNESNS) of licorice extract on an induced chronic IBD-like model in rats.

Locally advanced tumors (T3) are pretreated neoadjuvantly (radiochemotherapy) or perioperatively (chemotherapy). A differentiated primary staging and an interdisciplinary case presentation are of essential importance today.

On the other hand, vascular endothelial growth factor receptor 2 (VEGFR-2) is highly expressed in tumor-associated endothelial cells, where it affects tumor-promoting angiogenesis. Therefore, VEGFR-2 is considered one of the most promising therapeutic targets for cancer treatment.

We examined the course of CVP-I including results of an antibiotic eradication attempt of CVP-BSI. We investigated adults with CVP-I from 2010 to 2018 who had to undergo port explantation or were treated by a combination of systemic antibiotics and antibiotic lock therapy (ALT).

Accordingly, cationic bile-based vesicles were prepared as pro-bile-based vesicles and diethylaminoethyl dextran (DEAE-Dx)-stabilized bile-based vesicles to increase their stability without negatively affecting their hepatic affinity. The prepared bile-based vesicles were characterized for particle size, polydispersity index, ζ-potential, in vitro daclatasvir release, and ex vivo permeation using non-everted gut sac intestine.

It was encapsulated within bile based vesicles (BBVs) containing egg phosphatidyl choline, cholesterol and sodium deoxycholate fabricated by thin-film hydration method. A D-optimal mixture design was applied to study the effect of formulation variables on vesicular characteristics.

View Article and Find Full Text PDFUsing semi-quantitative microarray technology, almost every one of the approximately 30 000 human genes can be analyzed simultaneously with a low rate of false-positives, a high specificity, and a high quantification accuracy. This is supported by data from comparative studies of microarrays and reverse-transcription PCR for established cancer genes including those for epidermal growth factor receptor (EGFR), human epidermal growth factor receptor-2 (HER2/ERBB2), estrogen receptor (ESR1), progesterone receptor (PGR), urokinase-type plasminogen activator (PLAU), and plasminogen activator inhibitor-1 (SERPINE1). As such, semi-quantitative expression data provide an almost completely comprehensive background of biological knowledge that can be applied to cancer diagnostics.

Objective: Patients with small cell lung cancer (SCLC) are frequently denied surgical treatment despite growing body of evidence for a longer duration of remission and overall survival, if surgical intervention is integrated in a tri-modality therapy concept including chemotherapy, surgery, and radiotherapy.
Methods: A retrospective analysis was performed using data derived from 95 patients with SCLC operated upon over a period of 9 years. A subset of these patients was primarily operated upon and being diagnosed as SCLC only after thoracotomy, received radio-/chemotherapy postoperatively (n=64, group I).
Objective: In a prospective study, the effect of thymectomy on the pulmonary status of 50 consecutive patients with myasthenia gravis was evaluated over a time range of 4 years in the Chest and Chest surgery departments in the Cairo University Clinics and Thoracic Surgery Department of the Evangelisches Krankenhaus Duisburg-Nord.
Methods: The patients were divided into two groups: Group I included 26 patients who underwent thymectomy through median sternotomy. The mean age of the patients in this group was 24.

The effect of single and consecutive doses of reserpine on the morphology and cellular and nuclear sizes of adrenaline and noradrenaline cells in the adrenals of mice were compared with the normal controls receiving saline injections as a placebo. Adopting micrometric measurements for apparent cellular and nuclear diameters, the pooled mean volumes of adrenaline- and noradrenaline-secreting cells and nuclei were calculated. Normal controls, subjected to consecutive daily saline injections for a period of 2 weeks, presented an increase in the intensity of the chromaffin reaction and higher values of cellular and nuclear sized of both cell types than those receiving single saline injection.
