Exploitation of nanocarriers provides a compartment for enclosing drugs to protect them from degradation and potentiate their therapeutic efficiency. In the current study, amitriptyline- and liraglutide-loaded proniosomes were constructed for management of diabetic neuropathy, a serious complication associated with diabetes, that triggers spontaneous pain in patients and results in impaired quality of life. The developed therapeutic proniosomes were extensively characterized via dynamic light scattering, scanning electron microscopy, transmission electron microscopy, and Fourier transform-infrared spectroscopy.

Secukinumab (Secu) is an immunoglobulin G1 monoclonal antibody that exhibits anti-inflammatory activity by inhibiting several cellular signaling molecules. This study aimed to examine pulmonary protective potential of Secu in SUN-induced pulmonary fibrosis mediated through inhibition of inflammation via targeting IL-17A associated signaling pathway and using pirfenidone (PFD), an antifibrotic drug approved in 2014 for treatment of pulmonary fibrosis with IL-17A as one of its targets, as a reference drug.

In the current study, a selective inhibitor for human CA isoforms IX and XII (isatin-bearing sulfonamide, WEG-104), was incorporated into nanosized spherical niosomes at high encapsulation efficiency to allow for an enhanced and sustained antitumor activity. In vivo, administration of WEG-104 that is either free (10 mg/kg) or loaded into niosomes (5 mg/kg) into a mice model of Ehrlich ascites solid tumor resulted in comparable efficacy in terms of reduction of tumor weight and volume.

Available therapies do not provide definite cure, thus, there is an urge to seek for alternative treatments. Quercetin is a natural flavonoid that possesses antioxidant and anti-inflammatory properties.

Different miRs play a role in HF, and their targeting was suggested as a promising therapy. We aimed to target miR-24, a suppressor upstream of junctophilin-2 (JP-2), which is required to affix the sarcoplasmic reticulum to T-tubules, and hence the release of Ca in excitation-contraction coupling using pachymic acid (PA) and/or losartan (LN).

Postmenopausal women are at an increased risk of vascular calcification which is defined as the pathological deposition of minerals in the vasculature, and is strongly linked with increased cardiovascular disease risk. Since estrogen-replacement therapy is associated with increased cancer risk, there is a strong need for safer therapeutic approaches. In this study we aimed to investigate the protective and therapeutic effects of the phytoestrogen resveratrol against vascular calcification in ovariectomized rats, a preclinical model of postmenopause.

We proposed that coffee, the most popular beverage worldwide, may protect against the progression of Alzheimer's disease (AD). We investigated the protective potential of decaffeinated green coffee bean extract (GCBE) and the possible potentiation of pioglitazone (PIO) effects by decaffeinated GCBE in fructose-induced AD in rats.

Because of limited treatment options, new treatment strategies are mandatory. Green coffee bean extract (GCBE) was reported to attenuate IR and improve brain energy metabolism.
