Catechin is a naturally occurring flavonoid of the flavan-3-ol subclass with numerous biological functions; however, these benefits are diminished due to several factors, including low water solubility and degradation in the stomach's harsh environment. So, this study aimed to develop an intelligent catechin colon-targeting delivery system with a high loading capacity. This was done by coating surface-decorated mesoporous silica nanoparticles with a pH-responsive enteric polymer called Eudragit®- ...

These changes may be reflected in early atherosclerosis and cardiovascular risks. We aimed in this study to examine the carotid artery intima-media thickness and MRI brain findings in SSc patients and compared them to a group of normal controls. A relationship between these parameters and clinical measures in SSc was also sought. ...

The histology and structure of 38 spleens of the dromedary (aged 0.5–15 y) were studied in relation to age. The spleen was found to have a thick capsule (292±106 mm) divided into an outer layer (113±39 mm) composed mainly of connective tissue and an inner layer (180±81 mm) consisting mainly of smooth muscle cells. Vascular and avascular trabeculae extend from the capsule, the former containing arteries and nerves but no trabecular veins, the latter being divided structurally into primary and secondary ...

Limited information is available about predictors of short-term outcomes in patients with exacerbation of chronic obstructive pulmonary disease (eCOPD) attending an emergency department (ED). Such information could help to stratify these patients and guide medical decision-making. The aim of this study was to develop a clinical prediction rule for in-hospital mortality of eCOPD. The study was conducted on 100 consecutive adult patients, who were admitted to the Emergency Medical Department in Alexandria ...

Although chemotherapeutic agents represent a cornerstone of cancer treatment, chemotherapy-induced nausea and vomiting (CINV) affect the patients' quality of life and basic daily activities. Rolapitant is a novel selective neurokinin-1 receptor antagonist (NK-1 RA), which was clinically approved for prevention of CINV. The aim of the present study is to synthesize evidence about the safety and efficacy of rolapitant in combination with other antiemetic agents for prophylaxis against CINV. We performed ...

Previous studies reported disrupted hepatic function and structure following the administration of cyclosporine A (CsA) in humans and animals. Recently, we found that avocado seeds (AvS) ameliorated CsA-induced nephrotoxicity in rats. As a continuation, herein we checked whether AvS could also attenuate CsA-induced hepatotoxicity in rats. Subcutaneous injection of CsA (5 mg/kg) for 7 days triggered hepatotoxicity in rats, as indicated by liver dysfunction, redox imbalance, and histopathological changes. ...
