objective: several vaccines against hiv have been investigated but none has been approved as an effective hiv vaccine. an approach that could induce stronger immune response against the pathogen is utilizing a multi-epitopic vaccine. this strategy was used in the design of several vaccines and resulted in improved immune responses. materials and methods: in this study a multi-epitopic fusion p...

Lead-free (1-x)Bi0.5(Na0.80K0.20)0.5TiO3-xBaTiO3 or (1-x)BNKT-xBT (x = 0 – 0.15 mol fraction) piezoelectric ceramics have been investigated. The optimum density was found for the ceramic sintered at 1125°C, corresponding 98 99% of their theoretical values. All had a single perovskite structure. coexisting mixed tetragonal-rhombohedral phases all over entire compositional range with tetragonal p...

Background Schisandrin A (SchA) has multiple pharmacological features, and inflammatory bowel disease (IBD) represents a common digestive system mainly characterized by inflammation. Objectives To assess the anti-inflammatory effects mechanism of SchA in mice with enteritis MODE-K cells representing vivo vitro models Materials Methods DSS-induced IBD mouse (an model intestine) were used to on i...

Two new complexes [Fe(3-bpp)2](XO4)2·solv (X = Cl, 1 and Re, 2) have been prepared. Both systems show desolvation-assisted spin crossover (DASCO) light-induced excited spin-state trapping (LIESST) phenomena.

       Many studies have proved that the dietary micronutrient has an inhibitory effect against experimentally induced rat hepatocarcinogenesis. The present work is an attempt to understand combined effect of selenium (Se) and vitamin D3 (vit D3) on some potential protein expression markers of carcinogenesis, such as metallothionein (MT), P53 and antioxidant levels during ...

This study aimed at investigating the effects of intraperitoneal (IP) administration of magnesium sulfate (MgSO4) on testicular ischemia-reperfusion (IR) injury in rats. In total, 50 adult Wistar rats were randomly divided into 5 groups. Group 1 received no injection (control); however, group 2 was subjected to 2 h of I and 24 h of R. Subsequently, group 3 was subjected to 2 h of 1, ...

Hafnia-based thin films exhibit unconventional ferroelectricity. These materials also show rich polymorphism, and thus temperature field-driven phase transitions, as well oxygen migration. In a bigger context of exploring the synergy between ferroelectricity diffusion-based structural phenomena, here we study temperature-dependent transitions in epitaxial Hf0.5Zr0.5O2(HZO)/La0.67Sr0.33MnO3 (LSM...
