Preeclampsia is hypertension in pregnancy that affects 2% to 8% of pregnancies worldwide and causes significant maternal and perinatal morbidity and mortality. In the pathogenesis of preeclampsia, placental hypoxia plays an important role, associated with excessive trophoblast apoptosis resulting in decreased trophoblast and spiral arteries invasion. This placental hypoxic condition will induce increased expression of Hypoxia Inducible Factor -1-Alpha (HIF-1-A). L-Arginine is a potent vasodilator presumably to improve preeclampsia placental hypoxic conditions and reduce HIF-1-A expression. This study was an experimental study with a parallel-group post-test only design. Thirty-six preeclamptic mice models were divided into 2 groups. The control group (K1) 18 preeclamptic mice model without treatment and the treatment group (K2) 18 preeclamptic mice given L-Arginine. The independent variable was the administration of L-Arginine and the dependent variable is the placental HIF-1-A expression. Statistical analysis used unpaired t-test on normal data distribution, and Mann Whitney test on abnormal data distribution. The mean of placental HIF-1-A expression K1 was 2.47 ± 1.65 with a minimum value of 0.4 and a maximum value of 6.6. At K2 0.93 ± 0.55 with a minimum value of 0.0 and a maximum value of 2.0. Statistical tests showed that the placental HIF-1-A expression in the treatment group was significantly lower than that in the control group (p <0.001). In conclusion, the expression of HIF-1-A in preeclamptic mice model placenta decreased with L-Arginine administration.

Hypoxia in endometriosis will increase the expression of Hypoxia Inducible Factor-1alpha (HIF1alpha) and its expression could be decreased by Hyperbaric Oxygen (HBO). This study aimed to analyze the effect of HBO 2.4 ATA for 3x30 minutes per day for 10 days on the expression of HIF-1 alpha and endometriotic tissue size on mice model of endometriosis. This study was an experimental laboratory study with a separate pretest-posttest control group design. The mice were divided into three groups, the first was a pretest control group (which describes the condition after endometrium transplantation), the second was the endometriotic group that received hyperbaric oxygen, and the third was the endometriotic group that did not receive hyperbaric oxygen therapy. The endometriosis implant size in the peritoneal tissue was assessed and the immunohistochemistry examination was conducted to determine the expression of HIF-1 alpha. The endometriosis tissue size was reduced in the HBO group compared to the control and nonHBO group. The lowest expression of HIF-1 alpha was significantly found in HBO over the other group. The decrease of HIF1 alpha expression mediates the reduction of size endometriotic tissue due to the therapy of HBO.

Retrograde menstruation lead to I Kappa B Kinase (IKK) fosforilation in peritoneum macrophage and cause secretion of proinflammatory cytokine interleukin1β then stimulate endometriosis cell to produce Vascular Endothelial Growth Factor which lead to increasing of endometriosis lession seen as endometriosis implant area. Cytokine secretion was inhibited through prevention of NF-κB activation by dragon red fruit rind extract (Hylocereuspolyrhizus). The aim of this reserach is to know the effect of dragon red fuit rind extract with 0,25; 0,5; and 1 mg/g bodyweight dosage toward IL-1β, VEGF expression and implant area in endometriosis mice model. The design of this experiment was randomized post test only control group design.Endometrios mice model were made in 14 days and split into two group, positive control group and treatment group after two week negative control group and postive control group were given Na-CMC 0,5% solution consequetively, and treatment group were given dragon red fruit extract with different dosage. Signification number for IL-1β is p>0,05, signification number for VEGF is p>0,05, and implant area signification number is p>0,05. Administration of dragon red fruit rind extract can decrease IL-1β, VEGF, and implant area.

BACKGROUND: New laboratory and instrumental technologies for analyzing the adaptive capabilities of a biological organism to acute stressful effects including hypoxic ones have significantly facilitated the diagnosis and fixation of adaptive behavioral reactions, physiological and biochemical changes. Much attention has been paid to the phenomenon of preconditioning a positive effect from exposure to small doses of pathogenic factors. Hypoxia-inducible factor 1 (HIF-1) is one of the most promising markers for fixing the phenomenon of hypoxic preconditioning. AIM: To study the mechanisms of neuroadaptation to acute stressful effects. MATERIALS AND METHODS: Using models of immobilization, hypothermic exposure, and electrocutaneous irritation of rat paws were carried out for the assessment of the mechanisms of neuroadaptation. Changes in the HIF-1 concentration were recorded in the blood and in the structures of the brain. RESULTS: The maximum concentration of HIF-1 was found in the amygdala (230 pg / mg), in the prefrontal cortex it was 50.8 pg / mg in the control group. Hypothermal exposure increased the HIF-1 content in the amygdala by more than 4 times, while emotionally pain and immobilization showed a slight decrease in HIF-1 in the amygdala. All types of stressors significantly increased the concentration of HIF-1 in the prefrontal cortex of animals. The most pronounced changes were observed when using the model of emotional pain stress. The obtained experimental data allow us to draw with caution a conclusion about the universality and unity of multicomponent mechanisms of adaptation to acute stressful effects.

Abstract Objectives: To find the association of single nucleotide polymorphism of hypoxia-inducible factor-1 alpha, rs11549465 (1772 Cytosine > Thymine) with metabolic syndrome, and to compare the anthropometric and biochemical variables in different genotypes of hypoxia-inducible factor-1 alpha. Methods: The cross-sectional comparative study was conducted at the University of Health Sciences, Lahore, Pakistan, from July 2016 to April 2019, and comprised patients of metabolic syndrome selected from the Sheikh Zayed Hospital, Lahore. Healthy controls were also enrolled. Fasting venous sample was taken for the determination of study parameters. The genetic variant of hypoxia-inducible factor-1 alpha was analysed by restriction fragment length polymorphism polymerase chain reaction. Data was analysed using SPSS 22. Results: Out of 400 subjects, 200(50%) each were patients and controls. The frequency of CC genotype of hypoxia-inducible factor-1 alpha Cytosine > Thymine in patients was 166(83%) and in controls 147(73.5%); CT genotype was 34(17%) and 53(26.5%) respectively, while TT genotype was not observed. There was a significant association of the C allele and CC genotype (p=0.03) with the increased risk of metabolic syndrome (p=0.02). On comparison of study variables in the two genotypes, systolic blood pressure, anthropometric and lipid parameters were significantly higher in the wild CC genotype compared to CT in the control group (p<0.05), but there was no significant difference in the patients (p>0.05). Conclusion: Major allele C of hypoxia-inducible factor-1 alpha 1772 Cytosine > Thymine was found to be associated with increased risk of metabolic syndrome. Continuous...

The aim of the present study was to investigate the effect of hypoxia-inducible factor 1α (HIF1A) on the early healing (4 weeks) of extraction sockets exhibiting partial loss of the labial bone. Two extraction sockets of the maxillary incisors from each of six dogs were assigned to two treatment modalities: deproteinized bovine bone mineral (i) with 10% collagen (DBBM-C) soaked with HIF1A and covered by a collagen membrane (CM) (HIF group) or (ii) treated with DBBM-C only and covered by a CM (control group). Microcomputed tomography revealed some degree of collapse of the labial contour. The totally augmented volume and new bone volume did not differ significantly between two groups (P>0.05). The histological analysis revealed that the apical area of the socket was mostly filled with newly formed bone, while there was less newly formed bone in the coronal area and incomplete cortex formation. The histomorphometric analysis revealed that the area of newly formed bone was significantly larger in the HIF group than the control group (12.16±3.04 versus 9.48±2.01 mm2, P<0.05), while there was no significant intergroup difference in the total augmented area. In conclusion, even though DBBM-C soaked with HIF1A enhanced histomorphometric bone formation, this intervention did not demonstrate superiority in preventing ridge shrinkage compared to DBBM-C alone. Clinical relevance of these findings should be further studied.

Diabetes mellitus is a disease or metabolic disorder that is most often found in society, including one of the diseases or metabolic disorders. Tamarind leaves (Tamarindus indica L) is a plant that can be used as an alternative treatment for Diabetes Mellitus which contains flavonoids, sapoin and tannins, which can lower glucose levels and inhibit glucose absorption in the blood. This study aims to determine the differences in blood sugar levels before and after giving tamarind leaves infusion in the village community of Tanjung Bumi. This type of research is Quasy Experiment Design and purposive sampling technique with a sample of 29 respondents. Based on the results of the paired t-test statistical analysis showed a significant difference (p = 0.000) between the blood sugar levels of the group and placebo. Meanwhile, in the posttest the treatment group after giving tamarind leaves showed the same as the control group, namely p = 0.000, which means that there is also a difference in the decrease in blood sugar levels between the sebelum pemberian perlakuan and posttest. The results of statistical tests with the Independent T-Test showed the results in both groups with a value of p = 0.000, meaning that there was a difference in the decrease in blood sugar levels between the control group and the treatment group. Steeping tamarind leaves has an effect in reducing blood sugar levels in the body

Abstract Background PCV2 (Porcine circovirus type 2) is one of the major pathogens commonly in pigs, which can cause immunosuppression and apoptosis. Vaccinations and single drugs are not totally prevent and treat PCV2 diseases. We have previously reported that the synergistic anti-PCV2 effects of Matrine and Osthole were better than Matrine or Osthole alone in vitro, Matrine and Osthole were purchased with a clear content, chemical structure and plant origin. This study aimes to evaluate theirs synergistic anti-PCV2 effect and mechanism in Kunming (KM) mice model infected with PCV2. KM mice were randomly divided into 8 groups, namly: normal control group, PCV2 infected group, Matrine combined with Osthole high dose treatment group (40 mg/kg + 12 mg/kg), medium dose treatment group (20 mg/kg + 6 mg/kg), low dose treatment group (10 mg/kg + 3 mg/kg), Matrine treatment group (40 mg/kg), Osthole treatment group (12 mg/kg) and Ribavirin positive control group (40 mg/kg). PCV2 was intraperitoneally (i.p.) injected in all mice except the normal control group. At 5 days post-infection (dpi), mice in different treatment groups were injected i.p. with various doses of Matrine, Osthole and Ribavirin once daily for 5 consecutive days. Results The synergistic inhibition effect of Matrine and Osthole on PCV2 replication in mouse liver was significantly stronger than that of Matrine and Osthole alone. The protein expression of GRP78, p-PERK, p-eIF2α, ATF4, CHOP, cleaved caspase-3 and Bax were significantly reduced, but the protein expression of Bcl-2 was significantly increased in Matrine combined with Osthole groups, which alleviated the pathological change caused by PCV2, such as interstitial pneumonia, loss of spleen lymphocytes, infiltration of macrophages and eosinophils. Conclusions The synergistic effect of anti-apoptosis was better than that of Matrine and Osthole alone, although both of Matrine and Osthole could also directly inhibited the expression of PCV2 Cap and then inhibited the apoptosis of spleen cells induced by PCV2 Cap through the PERK pathway activated by endoplasmic reticulum (ER) GRP78. These results provide a new insight into controlling PCV2 infection and provide good component prescription candidate for the development of novel anti-PCV2 drugs.

Background: equine sarcoids are the most frequent skin tumors in equidae worldwide. It is well known that delta bovine papillomaviruses are their causative agents. We have recently shown the presence in equine sarcoids of abnormal vessel structures, which could cause a hypoxic condition. The aim of this study was to analyze the expression of hypoxia-inducible factor-1 alpha (HIF-1α) in a subset of BPV positive equine sarcoids and explore the relationship with vascular endothelial growth factor (VEGF) expression. Results: 80% of equine sarcoids showed strong cytoplasmic staining in >60% of neoplastic fibroblasts, while 20% of samples showed a moderate cytoplasmic staining in 40–60% of neoplastic fibroblasts for HIF-1α. Results of Western blotting (WB) were consistent with immunohistochemistry (IHC). Moreover, a positive correlation between HIF-1α and VEGF expression (r = 0.60, p < 0.01) was observed. Conclusion: we have shown that HIF-1α was strongly expressed in equine sarcoid. The upregulation of HIF-1α has been described in numerous tumors and can be modulated by many proteins encoded by transforming viruses. Thus, it is also possible that BPV could have a relevant role in HIF-1α pathway regulation, contributing to the development of equine sarcoids by promoting HIF-1α/VEGF mediated tumor angiogenesis.
