While, systemic Fas mRNA expression increased as malignity progressed; systemic
L mRNA expression was increased in low- and high-grade lesions, but it was decreased in cancer patients. Soluble FasL levels decreased as lesions progressed, while soluble Fas levels increased. Finally, overexpression of Fas/FasL on the surface of peripheral blood mononuclear cells was found in patients with low-grade lesion with respect to healthy donors.

Fas and FasL act as negative modulators of the immune response, probably by removing specific cytotoxic T lymphocytes against papillomavirus -infected cells and tumor cells.

Global cerebral ischemia (GCI), a consequence of cardiac arrest (CA), can significantly damage the neurons located in the vulnerable hippocampus CA1 areas. Clinically, neurological injury after CA contributes to death in most patients. Mastoparan-M extracted from
(Smith) can be used to treat major neurological disorders. Hence, this study aimed to assess the effects of Mastoparan-M on GCI.

To evaluate the neurotoxicity and neuroprotective effect of Mastoparan-M, the CCK8 and Annexin V-FITC/PI apoptosis assays were first performed in hippocampal HT22 neuronal cells
. Omipalisib chemical structure Then, Pulsinelli's 4-vascular occlusion model was constructed in rats. After treatment with Mastoparan-M (0.05, 0.1, and 0.2 mg/kg, IP) for 3 or 7 days, behavioral tests, H&E staining or Nissl staining, immunohistochemistry, and ELISA were employed to investigate neuroprotective effects of Mastoparan-M on GCI in rats.

, the growth of HT22 neuronal cells was restrained at concentrations of 30-300 µg/ml (at 24 hr, IC
=105.2 µg/ml; at 48 hr, IC
=46.81 µg/ml), and Mastoparan-M treatment (0.1,1 and 5 µg/ml) restrained apoptosis.
, Mastoparan-M improved neurocognitive function and neuronal loss in the hippocampal CA1 area of rats. In addition, these effects were associated with the prevention of neuroinflammation, oxidative stress, and apoptosis.

Folic acid is an essential vitamin, labile to hydrolysis in the acidic environment of the stomach with low water solubility and bioavailability. In order to solve these problems, enteric oral folic acid-loaded microfibers with a pH-sensitive polymer by electrospinning method were prepared.

Electrospinning was performed at different folic acid ratios and voltages. Fibers were evaluated in terms of mechanical strength, acidic resistance, and drug release. Additionally, DSC (Differential Scanning Calorimetry), FTIR (Fourier-transform infrared spectroscopy), and XRD (X-ray diffraction) analyses were performed on the optimal formulation.

Drug ratio and voltage had a considerable effect on fibers' entrapment efficiency, acid resistance, and mechanical strength. Based on the obtained results, the optimum formulation containing 1.25% of the drug/polymer was prepared at 18 kV. The entrapment efficiency of the optimal sample was above 90% with an acid resistance of higher than 70%. The tensile test confirmed the high mechanical properties of the optimum microfiber. DSC and XRD tests indicated that folic acid was converted to an amorphous form in the fiber structure and the FTIR test confirmed the formation of a chemical bond between the drug and the polymer. The release of the drug from the optimal fiber was about 90% in 60 min.

In conclusion, the optimal formulation of folic acid with proper mechanical properties can be used as a candidate dosage form for further bioavailability investigations.

Brain cancer treatments have mainly failed due to their inability to cross the blood-brain barrier. Several studies have confirmed the presence of glutathione (GSH) receptors on BBB's surface, as a result, products like 2B3-101, which contain over 5% pre-inserted GSH PEGylated liposomal doxorubicin, are being tested in clinical trials. Here we conducted the PEGylated nanoliposomal doxorubicin particles that are covalently attached to the glutathione using the post-insertion technique. Compared with the pre-insertion approach, the post-insertion method is notably simpler, faster, and more cost-effective, making it ideal for large-scale pharmaceutical manufacturing.

The ligands of the DSPE PEG(2000) Maleimide-GSH were introduced in the amounts of 25, 50, 100, 200, and 400 on the available Caelyx. Following physicochemical evaluations, animal experiments such as biodistribution, fluorescence microscopy, and pharmacokinetics were done.

In comparison with Caelyx, the 200L and 400L treatment arms were the mos method.
, as an opportunistic pathogen, is known to cause nosocomial infections among patients suffering from burn injuries and also cystic fibrosis patients. The objective of our research was to develop a novel vaccine against
.

A recombinant
subunit vaccine based on the outer membrane proteins, including the OprF-OprI region and its major protein in the type III secretion system, PopB (called FIB protein) was formulated. To induce a robust immune response, our preferred regions were conjugated to a carrier protein, GMCSF (Granulocyte-macrophage colony-stimulating factor). FIB protein's immunogenicity with and without adjuvant was evaluated in vaccinated rats and also burned rat models, which were subcutaneously challenged by the PAO1 strain of
.

Antibody levels were increased in sera of rats in this study. Assessment of the resident memory CD4+ T cells in splenocytes from vaccinated rats demonstrated that the FIB conjugated with GMCSF could cause higher responses in comparison with other groups. Moreover, immunization with the FIB plus adjuvant protein could improve interferon-gamma (IFN-γ) production, interleukin 17A (IL-17A), and IL-4, contributing to elicit humoral and cellular immune responses and decreased post-infection bacterial loads after PA challenge, pathology, and inflammatory cell infiltration.

These observations demonstrated that FIB conjugated with GMCSF can be a putative vaccine candidate against
in burnt rat models.

Many people all around the world encounter major problems due to nervous system injuries. Among the various methods of treating, neural tissue engineering has attracted a lot of attention from nerve science researchers.

There are various methods for fabrication of soft tissue, however the electrospinning method (ELS) is a simple and cost-effective method that can produce porous fiber scaffolds to simulate the environment of the extracellular matrix (ECM). In this study, an ELS technique was used to fabricate polyvinyl alcohol (PVA) tissues and graphene nanosheet (Gr-NS) added with omega-3 fatty acids (O3FA) was loaded in these tissues that support nerve tissue regeneration. For this purpose, PVA and Gr-NS for biaxial ELS, PVA containing 0.5 wt%, and 1 wt% of Gr-NS was used.. Then, the morphology of these scaffolds was observed by optical microscopy and scanning electron microscopy (SEM) technique.

The results show after loading of O3FA, the fiber diameter reaches 0.573±0.12 µm, which is within the range of dimensions required for nerve tissue engineering. FTIR analysis indicates that Gr-NS and O3FA have been well loaded in the scaffolds. The results of water absorption and biodegradation tests demonstrated that the sample with 0.5% Gr-NS has 211.98% and 16.54% water absorption and biodegradation after 48 hr and 6 days, respectively.

Finally, the results of this study indicate that scaffolds loaded with 0.5% Gr-NS have a homogeneous, porous, and integrated structure which can be effective in nerve tissue engineering.

Lifestyle and eating habits affect the health and function of the body's organs, including the kidneys. The current study was carried out to determine the effects of two types of diet programs, including time restriction (TR) and calorie restriction (CR) on the histopathological changes and apoptotic molecules during acute kidney injury (AKI) in postmenopausal rats.

In this study the female rats were divided into two groups of ovariectomized (OVX) and ovary-intact (sham), then they were placed on TR and CR diets for 8 weeks; afterward, AKI was induced by injection of glycerol. Functional indices, histopathological changes, Bax, and Bcl2 were measured before and after AKI.

After AKI, creatinine, serum urea, urinary albumin excretion, kidney tissue Bax, and Bax/Bcl2 ratio increased, while glomerular filtration rate (GFR) and kidney tissue Bcl2 decreased compared with before AKI. Histopathological indices (inflammation, cellular necrosis, cell vacuolization, tubular dilatation, intratubular cast, and congestion) also confirmed renal injury. TR and CR diets improved renal injury indices and prevented an increase in the Bax/Bcl2 ratio. However, in some indices, the effects of two diets on OVX animals were not observed. In addition, none of the diets could decrease kidney weight/body weight ratio (KW/BW). The histopathological finding also showed improvement of renal status in both groups, especially in the CR diet.

The results indicated that TR and CR diets had renoprotective effects against AKI by reducing the Bax/Bcl2 ratio and improving apoptosis. The effects of CR were more than TR.

Cisplatin (CDDP) is a highly effective chemotherapeutic agent, but its clinical application has been limited by nephrotoxicity. Tanshinone Ⅰ (T-I), a phenanthrenequinone compound extracted from the Chinese herb Danshen, has been used to improve circulation and treat cardiovascular diseases. The aim of this study was to investigate the protective effect of T-I on CDDP-induced nephrotoxicity in mice.

The BALB/c mouse models of nephrotoxicity were established by a single intraperitoneal injection of 20 mg/kg CDDP on the first day of the experiment. Three hours prior to CDDP administration, the mice were dosed with 10 mg/kg and 30 mg/kg T-I for 3 consecutive days intraperitoneally to explore nephroprotection of T-I.

Treatment with T-I significantly reduced blood urea nitrogen and creatinine levels in serum observed in CDDP-administered mice, especially at a dose of 30 mg/kg. T-I at 30 mg/kg significantly decreased malondialdehyde levels and increased glutathione levels and the enzymatic activity of catalase in kidney tissue compared to CDDP. Additionally, T-I (30 mg/kg) significantly reversed the CDDP-decreased expression level of superoxide dismutase 2 protein in renal tissue. Histopathological evaluation of the kidneys further confirmed the protective effect of T-I.

The findings of this study demonstrate that T-I can protect against CDDP-induced nephrotoxicity through suppression of oxidative stress.
