Objectives: Cerium is a member of the rare metals group and widely used in drug delivery, gene therapy, molecular imaging and medicine. In this study, we investigated the effect of different doses of Cerium (IV) oxide (CeO ) during pregnancy on neonatal mice ovaries, as well as its effect on blood biochemical parameters.

Methods: Thirty pregnant NMRI mice were divided into five groups: Control and 4 groups treated with CeO (10, 25, 80, 250 mg/kg.bw i.p) at the GD7 and GD14. The ovarian histological of neonatal (2 and 6 day-olds), as well as blood serum of neonates at 15-dpp were analyzed.

Results: Count of ovarian primordial follicles in neonates at 2 dpp showed a significant decrease in the groups treated with 80 and 250 mg/kg.bw doses of CeO . There was also a significant decrease in ovarian primordial and primary follicles in neonates at 6-dpp at 250 mg/kg.bw doses of CeO in the control (P < 0.05). There was no significant difference in serum levels of malondialdehyde and total antioxidant capacity between the experimental and control groups.

Conclusions: Our results suggest that the effects of CeO on the ovarian tissue of neonatal mice during pregnancy may be dose-dependent.

Varied functions of immune checkpoints during cancer metastasis.

Cancer Immunol Immunother 2021 Mar 9;70(3):569-588. Epub 2020 Sep 9.

IRCCS IstitutoTumori "Giovanni Paolo II" of Bari, Bari, Italy.

Immune checkpoints comprise diverse receptors and ligands including costimulatory and inhibitory molecules, which play monumental roles in regulating the immune system. Immune checkpoints retain key potentials in maintaining the immune system homeostasis and hindering the malignancy development and autoimmunity. The expression of inhibitory immune checkpoints delineates an increase in a plethora of metastatic tumors and the inhibition of these immune checkpoints can be followed by promising results. On the other hand, the stimulation of costimulatory immune checkpoints can restrain the metastasis originating from diverse tumors. From the review above, key findings emerged regarding potential functions of inhibitory and costimulatory immune checkpoints targeting the metastatic cascade and point towards novel potential Achilles' heels of cancer that might be exploited therapeutically in the future.

Macrophage polarization in wound healing: role of aloe vera/chitosan nanohydrogel.

Drug Deliv Transl Res 2019 12;9(6):1027-1042

Department of Immunology, School of Medicine, Lorestan University of Medical Sciences, P.O. Box: 381351698, Khorramabad, Iran.

The balance between M1 and M2 macrophages plays an important role in wound healing. Interestingly, this immune response can be modulated by natural biomaterials such as chitosan nanohydrogel (Ch) and aloe vera (AV). Therefore, we aimed to improve wound recovery response by exploiting the potential healing properties of Ch and AV. Wounds were created in rats and were treated daily with either saline (control), AV, Ch, or different ratios of AV (volume):Ch (weight) (1:1), (2:1), and (3:1). M1 (iNOS, TNF-α) and M2 (CD163, TGF-β) responses were analyzed at days 3, 7, 14, 21, and 28. Wound healing increased within the third and seventh days in AV-Ch (3:1) (P < 0.001 and P < 0.002, respectively). In the treated groups, immunohistochemistry of iNOS expression decreased on the third day (P < 0.0001) while CD163 increased (P < 0.0001) on the 3rd, 7th, and 14th days. The gene expression of TGF-β decreased on the third day in AV group (P < 0.03) and on the 21st and 28th days in Ch-treated group (P < 0.00). TNF-α expression decreased in AV, Ch, and AV-Ch (3:1 v/w) on the 14th and 28th days (P < 0.00). TGF-β and TNF-α proteins decreased on the 28th day compared to the control and AV-Ch (3:1 v/w), respectively. AV-Ch (1 and 3:1 v/w) and Ch resulted in optimum wound repair by decreasing M1 after 3 days and increasing M2 after 14. Thus, Ch nanohydrogel, especially in combination with 1:1 and 1:3 ratio to AV, could be a proper candidate for modulating macrophages in response to wound healing.

The potential role of miR-29 in health and cancer diagnosis, prognosis, and therapy.

J Cell Physiol 2019 11 4;234(11):19280-19297. Epub 2019 Apr 4.

Immunology Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.

miR-29 family is one of the small noncoding RNAs and has a very important role in many physiologic and pathologic functions through regulating the target genes that play roles in various bioprocesses such as proliferation, survival, apoptosis, and angiogenesis. Thus, we aim to survey the potential of the miR-29 family in normal model and development and progression of malignancy in this study. In addition, the potential role of miR-29 family has been studied as the clinical marker for the diagnosis and prognosis of many cancers as the potential targets to treat cancer. Moreover, it was stated in summary that the herbal compounds can regulate miR-29 family in cancers. Therefore, regulating the expression of the miR-29 family in a variety of cancers can be a new strategy to obtain better results from cancerous patients' treatment in the future.

Background: Finding the best dressing for a specific had continued from the past to present. The aim of this study was to evaluate the of encapsulated extract of in hydrogel alginate at wound healing.

Methods: Thirty-two male Wistar rats with a puncture wound in the back of the neck skin were divided randomly into four groups including a control group, -treated group, hydrogel alginate-treated group, and encapsulated in hydrogel alginate-treated group. Rats were treated for 22 days. The skin samples were taken on 3rd, 7th, 14th, and 22nd days after treatment for light microscopy. Results were analyzed in accordance with Kruskal-Wallis and Friedman test (for histopathology analysis) by using SPSS v.22 software.

Results: Macroscopically evaluations and measurement of wound size showed increased wound healing process in the treated groups. The complete improvement was created on the 14th day. The wound site was not observed on the 22nd day. But the wound site was observed on the 22nd day in the control group. Also, comparison of the percentage of wound healing between the treated and control groups on 3rd, 7th, 14th, and 22nd days showed a significant difference ( < 0.05). Comparison of the H&E stained sections in the studied groups showed that treated groups were effective on wound healing in comparison with the control group.

Conclusions: Encapsulated extract of in hydrogel alginate may accelerate wound improvement and increase the rate of wound healing without scar formation.

A review of plant-based compounds and medicinal plants effective on atherosclerosis.

J Res Med Sci 2017 15;22:30. Epub 2017 Mar 15.

Medical Plants Research Center, Shahrekord University of Medical Sciences, Shahrekord, Iran.

Atherosclerosis is one of the most important cardiovascular diseases that involve vessels through the development of fatty streaks and plaques. Plant-based compounds can help treat or prevent atherosclerosis through affecting the involved factors. The main purpose of this review article is to investigate and introduce medicinal plants and their potential activities regarding antioxidant properties, effective on lipids level and development of plaque, atherosclerosis, and progression of atherosclerosis as well as the development of cardiovascular disease and ischemia. To search for the relevant articles indexed in Information Sciences Institute, PubMed, Scientific Information Database, IranMedex, and Scopus between 1980 and 2013, with further emphasis on those indexed from 2004 to 2015, we used these search terms: atherosclerosis, antioxidant, cholesterol, inflammation, and the medicinal plants below. Then, the articles with inclusion criteria were used in the final analysis of the findings. Plant-based active compounds, including phenols, flavonoids, and antioxidants, can be effective on atherosclerosis predisposing factors and hence in preventing this disease and associated harmful complications, especially through reducing cholesterol, preventing increase in free radicals, and ultimately decreasing vascular plaque and vascular resistance. Hence, medicinal plants can contribute to treating atherosclerosis and preventing its progression through reducing cholesterolemia, free radicals, inflammation, vascular resistance, and certain enzymes. They, alone or in combination with hypocholesterolemic drugs, can therefore be useful for patients with hyperlipidemia and its complications.
