Pancreatic Regeneration

Mesenchymal stem cell (MSC) therapy is an innovative approach in diabetes due to its capacity to modulate tissue microenvironment and regeneration of glucose-responsive insulin-producing cells. In this study, we investigated the role of MSC-derived exosomes in pancreatic regeneration and insulin secretion in mice with streptozotocin-induced diabetes. Mesenchymal stem cells (MSCs) were isolated and characterized from umbilical cord blood (UCB). Exosomes were isolated and characterized from these MSCs. Diabetes was induced in male C57Bl/6 mice by streptozotocin (STZ; 40 mg/kg body weight, i.p.) for five consecutive days. The diabetic mice were administered (i.v.) with MSC ( 1 × 10 5 umbilical cord blood MSC cells/mice/day), their derived exosomes (the MSC-Exo group that received exosomes derived from 1 × 10 5 MSC cells/mice/day), or the same volume of PBS. Before administration, the potency of MSCs and their exosomes was evaluated in vitro by T cell activation experiments. After day 7 of the treatments, blood samples and pancreatic tissues were collected. Histochemistry was performed to check cellular architecture and β cell regeneration. In body weight, blood glucose level, and insulin level, cell proliferation assay was done to confirm regeneration of cells after MSC and MSC-Exo treatments. Hyperglycemia was also attenuated in these mice with a concomitant increase in insulin production and an improved histological structure compared to mice in the PBS-treated group. We found increased expression of genes associated with tissue regeneration pathways, including Reg2, Reg3, and Amy2b in the pancreatic tissue of mice treated with MSC or MSC-Exo relative to PBS-treated mice. MicroRNA profiling of MSC-derived exosomes showed the presence of miRs that may facilitate pancreatic regeneration by regulating the Extl3-Reg-cyclinD1 pathway. These results demonstrate a potential therapeutic role of umbilical cord blood MSC-derived exosomes in attenuating insulin deficiency by activating pancreatic islets’ regenerative abilities.

Umbilical Cord Prolapse

Cord prolapse is an obstetric emergency as delay in management is associated with significantly increased neonatal morbidity and mortality. If the accident occurred outside the hospital, many babies would be dead or severely asphyxiated upon arrival in the hospital. The role of Accident & Emergency (A&E) department is to arrive at this diagnosis promptly and deliver appropriate intervention. Immediate cesarean delivery is the treatment of choice. The clinical presentations of two cases with umbilical cord prolapse presenting to our A&E department within two weeks were described. The pathophysiology, risk factors, diagnosis, management as well as outcome were discussed.

In experiments with 60 segments of arteries and 46 segments of the umbilical cord vein of 24 newborns and 35 strips of myometrium of 12 pregnant women, the effect of 100-fold dilutions of cord blood serum (SPK-1: 100) on the contractile effects of histamine (0.01, 0.1 and 1 ϻg l ml). SPK-1: - 100 increased the vasoconstrictor and uterostimulating effects of histamine. H1-histaminosensitizing activity of SPK-1: 100 and the efficiency of activation of H1-histamine receptors of myocytes of the arteries and umbilical cord veins are increased in the presence of obstetric complications. A conclusion was made about the content of endogenous sensitizer H1-histamine receptors (ESGR) in the fetal blood, the level of which increases in the presence of obstetric complications, as well as the possible role of histamine and ESGR in the regulation of fetoplacental blood circulation in conditions of normal and pathological conditions.

Background: Our previous studies have shown that Pygo (Pygopus) in Drosophila plays a critical role in adult heart function that is likely conserved in mammals. However, its role in the differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) into cardiomyocytes remains unknown. Objective: To investigate the role of pygo2 in the differentiation of hUC-MSCs into cardiomyocytes. Methods: Third passage hUC-MSCs were divided into two groups: a p+ group infected with the GV492-pygo2 virus and a p− group infected with the GV492 virus. After infection and 3 or 21 days of incubation, Quantitative real-time PCR (qRT-PCR) was performed to detect pluripotency markers, including OCT-4 and SOX2. Nkx2.5, Gata-4 and cTnT were detected by immunofluorescence at 7, 14 and 21 days post-infection, respectively. Expression of cardiac-related genes—including Nkx2.5, Gata-4, TNNT2, MEF2c, ISL-1, FOXH1, KDR, αMHC and α-Actin—were analyzed by qRT-PCR following transfection with the virus at one, two and three weeks. Results : After three days of incubation, there were no significant changes in the expression of the pluripotency stem cell markers OCT-4 and SOX2 in the p+ group hUC-MSCs relative to controls (OCT-4: 1.03 ± 0.096 VS 1, P > 0.05, SOX2: 1.071 ± 0.189 VS 1, P > 0.05); however, after 21 days, significant decreases were observed (OCT-4: 0.164 ± 0.098 VS 1, P < 0.01, SOX2: 0.209 ± 0.109 VS 1, P < 0.001). Seven days following incubation, expression of mesoderm specialisation markers, such as Nkx2.5, Gata-4, MEF2c and KDR, were increased; at 14 days following incubation, expression of cardiac genes, such as Nkx2.5, Gata-4, TNNT2, MEF2c, ISL-1, FOXH1, KDR, αMHC and α-Actin, were significantly upregulated in the p+ group relative to the p− group (P < 0.05). Taken together, these findings suggest that overexpression of pygo2 results in more hUCMSCs gradually differentiating into cardiomyocyte-like cells. Conclusion: We are the first to show that overexpression of pygo2 significantly enhances the expression of cardiac-genic genes, including Nkx2.5 and Gata-4, and promotes the differentiation of hUC-MSCs into cardiomyocyte-like cells.

Two Phases

Background and Aims: Women who develop GDM (gestational diabetes mellitus) have a relative insulin secretion deficiency, the severity of which may be predictive for later development of diabetes. This study aimed to investigate the role of fasting plasma glucagon in the prediction of later development of diabetes in pregnant women with GDM. Materials and Methods: The study was conducted on 150 pregnant women with GDM after giving informed oral and written consents and being approved by the research ethical committee according to the declaration of Helsinki. The study was conducted in two phases, first phase during pregnancy and the second one was 6 months post-partum, as we measured fasting plasma glucagon before and after delivery together with fasting and 2 hour post-prandial plasma sugar. Results: Our findings suggested that glucagon levels significantly increased after delivery in the majority 14/25 (56%) of GDM women who developed type 2 DM within 6 months after delivery compared to 6/20 (30%) patients with impaired fasting plasma glucose (IFG) and only 22/105 (20%) non DM women, as the median glucagon levels were 80,76, 55, respectively. Also, there was a high statistical difference between fasting plasma glucagon post-delivery among diabetic and non-diabetic women (p ≤ 0.001). These results indicated the useful role of assessing fasting plasma glucagon before and after delivery in patients with GDM to predict the possibility of type 2 DM. Conclusion: There is a relatively high glucagon level in GDM patients, which is a significant pathogenic factor in the incidence of subsequent diabetes in women with a history of GDM. This could be important in the design of follow-up programs for women with previous GDM.

Background: Every woman has the right to have children. Objective: This study aimed to investigate the Jurisprudence study of the importance of the role of a woman right to have a child. Methods: A review of the literature with keywords of motherhood. The viewpoints of the jurists, jurisprudent law, right contraception and breastfeeding, spiritual rewards, pregnant women, instinct of having a child and the Quran. The Information Centers such as Scopus and Iranmedex, Magi ran SID, Google Scholar, Science Direct, Pub med, and in the returns without any time limitations up to 2018. Therefore, Qur'anic verses based on the topic and authentic Hadith texts as well as authoritative, authentic scientific articles. Results: Narrations and Quran verses on greatness and respect of a mother show the importance of the maternal role. The maternal role is a fabulous facet of perfection of a woman and Islam has considered spiritual rewards for it. In the Quran, many biological changes such as pregnancy, childbirth, breastfeeding and taking care of a child and spiritual characteristics of mothers as the instinct seeking a child or generosity towards child have been mentioned. Islamic rules have a duty to extend this culture and aid mothers to achieve this right. Nobody can deprive a woman of it. Conclusion: In view of jurisprudent rules in Islam, if there is no limitation or natural barrier for a woman to have a child but her husband’s illogical unwillingness for having a child; this is, according to article 1130 of civil law, a kind of distress and embarrassment and the woman has the right to divorce.
