Abstract We here investigate the occurrence of fluoride intake-associated alterations in patients with hematologic disease on triazol antifungal medication. Clinical, laboratory, and radiology data of overall 43 patients with hematologic malignancies taking voriconazole (n = 20), posaconazole (n = 8), and itraconazole (n = 4), and a hematologic patient control group (n = 11) are described. Bone pain and radiologic evidence of periostitis were exclusively observed in patients receiving long-term voriconazole. Cessation of treatment led to clinical improvement in all cases. In line with clinical evidence, fluoride serum concentration was elevated in patients receiving voriconazole (median, 156.5 μg/L; interquartile range, 96.8 μg/L; normal < 30 μg/L) but not in the other treatment groups (P < .001 for all comparisons vs voriconazole). We conclude that serum fluoride levels were elevated on average 5-fold above normal levels in hematologic patients receiving voriconazole. Clinically relevant skeletal disease was associated with renal insufficiency and above 10-fold elevated fluoride levels, and was reversible on termination of voriconazole treatment.

Preeclampsia is a clinical manifestation of the physiological and psychological maladaptation in the pregnant woman. The objective: to determine the characteristics of the psychoemotional status of pregnant women with pre-eclampsia based on the results of psychological testing using questionnaires using the Spielberger-Khanin technique and studying the psychological component of the gestational dominant (PCGD) Dobryakov [3]. Materials and methods. The subject of this study was the results of clinical-laboratory and psychological testing of 90 women in the III trimester of pregnancy. In 50 women, moderate and severe preeclampsia was diagnosed and they were included in the main group, and 40 women with a physiological pregnancy were included in the control group. Results. Pathological subtypes of the psychological component of the gestational dominant are revealed by the method of IV. Dobryakova and an increase in anxiety level by the Spielberger-Khanin technique. The high level of anxiety, the absence of a dominant pregnancy or the presence of its pathological subtypes in the case of gestosis is both a reflection of the maladaptation of the whole organism and the woman's unwillingness to transform her stereotypes of behavior in accordance with the needs of a new condition-pregnancy and forthcoming births, Have long-term consequences even from offspring [5]. The conclusion. The necessity of psychological counseling of pregnant women and correction of the revealed violations of the period of gestation is proved. Key words: pregnancy, delivery, preeclampsia, perinatal psychology, anxiety, gestational dominant.

Supplementation plays an important role in reversing the weight loss of grazing yaks during cold season. However, little is known about the effect of supplementation on the serum metabolites of grazing yaks. The objective of this study was to explore the effects of supplementary feeding on average daily gain (ADG) and serum metabolites with nuclear magnetic resonance (NMR)-based metabolomics method in growing yaks during cold season on the Qinghai-Tibetan plateau. Twenty 1.5-year-old female yaks (91.38 ± 10.43 kg LW) were evenly divided into three treatment groups and a control group (CON) (n = 5 per group). All the yaks were released to graze during daytime, whereas the yaks in the treatment groups were supplemented with highland barley (HLB), rapeseed meal (RSM), and highland barley plus rapeseed meal (HLB + RSM) at night. The whole experiment lasted for 120 days. Results indicated that the ADG of growing yak heifers was increased by concentrate supplementations, and ADG under HLB and HLB + RSM group was 37.5% higher (p < 0.05) than that with RSM supplementation. Supplementary feeding increased the plasma concentrations of total protein (TP), albumin (ALB), and blood urea nitrogen (BUN) of those in the CON group, and concentrations of BUN were higher in the RSM group than in the HLB and HLB + RSM group. Compared with the CON group, serum levels of glutamine, glycine, β-glucose were lower and that of choline was higher in the HLB group; serum levels of lactate were lower and that of choline, glutamate were higher in the HLB + RSM group. Compared with the HLB + RSM group, serum levels of glycerophosphoryl choline (GPC) and lactate were higher, and those of choline, glutamine, glutamate, leucine, N-acetyaspartate, α-glucose, and β-glucose were lower in the HLB group; serum levels of citrate, GPC and lactate were higher, and those of 3-Hydroxybutyrate, betaine, choline, glutamate, glutamine, N-acetylglycoprotein, N-acetyaspartate, α-glucose, and β-glucose were lower in the RSM group. It could be concluded that concentrate supplementations significantly improved the growth performance of growing yaks and supplementation with HBL or HLB plus RSM was better than RSM during the cold season. Supplementation with HBL or HLB plus RSM affected the serum metabolites of grazing yaks, and both treatments promoted lipid synthesis. Supplementation of yaks with HBL plus RSM could improve energy-supply efficiency, protein and lipid deposition compared with HLB and RSM.

Oestradiol Production

ABSTRACT Hyperprolactinaemia disrupts fertility in many species, perhaps by inhibiting ovarian follicular steroidogenesis. The present studies measured oestradiol and progesterone secretion from isolated follicles from rats rendered hyperprolactinaemic in one of two ways. Sustained hyperprolactinaemia was induced by transplantation of two donor pituitary grafts under the renal capsule of adult female rats; grafts remained in place for 3 months. Transient hyperprolactinaemia was induced by pseudopregnancy initiated by cervical stimulation. Small antral follicles were isolated from both groups of rats 8–10 days after the previous vaginal oestrous smear and also from a control group of dioestrous female rats. Follicles were incubated for 3 h in the presence or absence of human chorionic gonadotrophin (hCG) or testosterone. Basal and hCG-stimulated oestradiol production were each reduced in follicles from both hyperprolactinaemic groups, relative to follicles from dioestrous control rats. In contrast, in the presence of testosterone, all groups of follicles produced comparable amounts of oestradiol. hCG stimulated comparable progesterone production by follicles from all three treatment groups. Testosterone elicited smaller increases in progesterone accumulation by follicles from all in-vivo groups. Reduced basal and gonadotrophin-stimulated, but not androgen-stimulated, oestradiol accumulation suggests that androgen production rather than aromatase activity in small antral follicles may be impaired by long-term hyperprolactinaemia.

OBJECT The optimal treatment for sporadic vestibular schwannoma (VS) is highly controversial. To date, the majority of studies comparing treatment modalities have focused on a narrow scope of technical outcomes including facial function, hearing status, and tumor control. Very few publications have investigated health-related quality of life (HRQOL) differences between individual treatment groups, and none have used a disease-specific HRQOL instrument. METHODS All patients with sporadic small- to medium-sized VSs who underwent primary microsurgery, stereotactic radiosurgery (SRS), or observation between 1998 and 2008 were identified. Subjects were surveyed via postal questionnaire using the 36-Item Short Form Health Survey (SF-36), the 10-item Patient-Reported Outcomes Measurement Information System short form (PROMIS-10), the Glasgow Benefit Inventory (GBI), and the Penn Acoustic Neuroma Quality-of-Life (PANQOL) scale. Additionally, a pool of general population adults was surveyed, providing a nontumor control group for comparison. RESULTS A total of 642 respondents were analyzed. The overall response rate for patients with VS was 79%, and the mean time interval between treatment and survey was 7.7 years. Using multivariate regression, there were no statistically significant differences between management groups with respect to the PROMIS-10 physical or mental health dimensions, the SF-36 Physical or Mental Component Summary scores, or the PANQOL general, anxiety, hearing, or energy subdomains. Patients who underwent SRS or observation reported a better total PANQOL score and higher PANQOL facial, balance, and pain subdomain scores than the microsurgical cohort (p < 0.02). The differences in scores between the nontumor control group and patients with VS were greater than differences observed between individual treatment groups for the majority of measures. CONCLUSIONS The differences in HRQOL outcomes following SRS, observation, and microsurgery for VS are small. Notably, the diagnosis of VS rather than treatment strategy most significantly impacts quality of life. Understanding that a large number of VSs do not grow following discovery, and that intervention does not confer a long-term HRQOL advantage, small- and medium-sized VS should be initially observed, while intervention should be reserved for patients with unequivocal tumor growth or intractable symptoms that are amenable to treatment. Future studies assessing HRQOL in VS patients should prioritize use of validated disease-specific measures, such as the PANQOL, given the significant limitations of generic instruments in distinguishing between treatment groups and tumor versus nontumor subjects.

Background: The risk of occupational exposure to acrylamide is high and long-term acrylamide exposure can cause neurotoxicity. Thus, therapeutic agents that can protect against acrylamide-induced neurotoxicity are needed. Objective: To investigate whether Grape Seed Extract (GSE) protects against acrylamide-induced neurotoxicity in mice. Methods: Mice were divided into saline, GSE, acrylamide, GSE followed by acrylamide, acrylamide followed by GSE, and simultaneous acrylamide and GSE treatment groups. Gene expression and antioxidant enzyme levels were then determined using RT-PCR and biochemical assays. Results: Gpx1 (P < 0.05), Prdx3 (P < 0.01), SOD1 (P < 0.05), and CAT (P < 0.05) significantly upregulated in GSE-treated mice, compared to those in untreated controls. In contrast, Gpx1 (P < 0.05), Prdx3 (P < 0.05), SOD1 (P < 0.05), and CAT (P < 0.05) significantly downregulated in acrylamide-treated mice compared to those in untreated controls. Results of the treatment with GSE before exposure to acrylamide or simultaneously with acrylamide indicated that GSE restored Gpx1, Prdx3, SOD1, and CAT expression to similar levels as those in the control group. GSE treatment after exposure to acrylamide did not exert any neuroprotective effects against acrylamide, as revealed by significant downregulation of Gpx1 (P < 0.05), Prdx3 (P < 0.01), SOD1 (P < 0.05), and CAT (P < 0.05) compared to that in untreated controls. Animals treated with grape seed before acrylamide treatment showed no significant change in LPO activities and a significant increase in GSH levels, compared to those in untreated controls. Conclusion: GSE exerted neuroprotective effects against acrylamide-induced neurotoxicity. Acrylamide caused oxidative stress 20 days post-exposure. However, grape seed treatment before exposure to acrylamide restored all test parameters to levels similar to control values.

Abstract Background: Prompt diagnosis of juvenile idiopathic arthritis (JIA) is important to avoid long term complications. Elevated serum 14-3-3η levels improve the diagnostic sensitivity of rheumatoid factor (RF) and cyclic citrullinated peptide (CCP) antibody in adult rheumatoid arthritis (RA), and have been associated with more severe phenotype. We investigated the prevalence and clinical significance of serum 14-3-3η in different types of JIA.Methods: JIA patients (n=151) followed by the Pediatric Rheumatology Core at Children’s Hospital of Los Angeles were categorized into 5 groups: polyarticular JIA RF+ (PJIA RF+; n=39), PJIA RF- (n=39), psoriatic arthritis (PsA; n=19), enthesitis-related arthritis (ERA; n=18), and oligoarticular JIA (OJIA [control group]; n=36). RF, CCP antibody, and 14-3-3η were measured for all patients. 14-3-3η serum levels >0.2ng/mL were considered positive. Disease activity was assessed by the Juvenile Arthritis Disease Activity Score-71 (JADAS-71). Results: Elevated 14-3-3h levels were detected in 34/151 (23%) patients, and across all groups tested. Most patients with 14-3-3h had titers ≥4 times above the cutoff value. The majority (22, 65%) of 14-3-3h-positive patients were also positive for RF or CCP antibodies, 16 (47%) were positive for all 3, and 12 (35%) were single-positive for 14-3-3η. The highest prevalence of 14-3-3η was in PJIA RF+ patients (49%), followed by OJIA (22%). Positivity for 14-3-3h was not significantly associated with disease activity or age at diagnosis. Conclusion: Serum 14-3-3h can be detected in all forms of JIA tested but appears to be most common in PJIA RF+. 14-3-3h does not appear to correlate with disease activity in JIA.

The Central Nervous System

Multiple sclerosis (MS) is the most common neurological disease that happens at a young age. MS is an inflammatory disease; associated with the demyelination of the central nervous system. Therefore, some inflammatory factors are effective in the mechanism and progression of the disease. Melatonin, as a multi-effect substance including anti-inflammatory effects, can reduce symptoms of MS in patients with a change in their inflammatory factors level. In this study, 50 MS patients who were referred to the MS Society of Markazi Province were randomly selected. All patients were treated with routine MS treatment (interferon) and were divided into control (25 placebo recipients) and treatment (25 recipients of 3 mg melatonin per day for 24 weeks) groups. Anthropometric data of patients including height, weight, and age were determined. Blood samples were collected after fasting in order to determine serum levels of interleukin 1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α). Then, samples were immediately centrifuged for serum separation and sera were transferred to a freezer at -80°C and serum levels of these factors were determined; using ELISA kit. The results of this study showed that there was no significant difference between the control and treatment groups in terms of serum levels of TNF-α. However, the level of IL-1β was significantly reduced in the treatment group compared to the control group, indicating that melatonin decreases this inflammatory substance. Our findings suggest a valuable strategy in the treatment of patients who suffer from MS

Purpose: To study the influence of N-acetylcysteine (NAC) on systemic lupus  erythematosus (SLE) mice, and the mechanism(s) involved. Methods: Fourteen MRL/lpr SLE mice aged 5 weeks (mean weight = 20.35 ± 2.12 g) were divided into two 7-mouse groups: SLE (control) and treatment groups. The control group comprised healthy female SPF-grade C57BL/6 mice (n = 7). The treatment group mice received intraperitoneal injection of NAC at a dose of 250 mg/kg daily for 8 weeks. The serum levels of malondialdehyde (MDA) and nitric oxide (NO), and activities of glutathione peroxidase (GPx) and superoxide dismutase (SOD), were assayed using standard methods. The level of urine protein and activity of anti-double stranded (ds) DNA antibody were determined using their respective enzyme-linked assay (ELISA) kits. Results: The spleens of mice in SLE mice were significantly enlarged, relative to control mice, but they were reduced significantly by NAC (p < 0.05). N-Acetylcysteine (NAC) also significantly reduced the serum levels of MDA and NO in SLE mice, but significantly  increased the serum activities of superoxide dismutase and GPx. Moreover, urine protein concentration and activity of anti-dsDNA antibody in SLE mice significantly increased, but reduced significantly by NAC treatment (p < 0.05). Conclusion: These results suggest that NAC effectively alleviates SLE in mice via regulation of oxidative stress. Thus, NAC has the potentials for development into a therapy for the management of SLE.

Background: Allergy is a hypersensitivity reaction due to induction of specific IgE binding to allergens on the surface of mast cells. Interleukin-5 is an important marker of hypersensitivity inflammation reactions.  Nigella sativa, contain active substance thymoquinone, can reduce inflammatory mediators. Zinc as anti-inflammatory by inhibit releasing mediators from mast cells. Objective was to determine the effect of Nigella sativa (NS) and zinc on IgE and IL-5 serum levels on ovalbumin-induced BALB/C mice.Methods: The study design was a true experiment with post-test only control group using BALB/C mice. The study was conducted at Sultan Agung Islamic University’s laboratory on March-June 2020. Inclusion criteria were female BALB C mice, 6-8 weeks, 22-25 grams, and healthy. Thirty mice were divided randomly into 5 groups; negative control, positive control, NS group, zinc group, and NS + zinc group. All groups treated for 28 days. Allergic reactions tested by skin test with OVA, intervention response assessed by IgE and IL-5 serum levels.Results: At the end of study completed, obtained 6 negative controls, 6 positive controls, 6 NS groups, 5 zinc groups, and 5 NS+zinc groups. Two mice s died before intervention completed. Serum IgE and IL5 levels were significantly difference between treatment groups (Kruskal Wallis test; p=0.007 and One-way ANOVA test; p=0.020). The result of logistic regression test, IgE levels was the most significant in the NS+zinc group (p=0.006) and IL-5 levels was the most significant in the zinc group (p=0.002)Conclusions:  Nigella sativa, zinc, and its combination can reduce IgE and IL-5 serum levels of ovalbumin-induced BALB / C mice.

Background: Epilepsy is the most common childhood neurological disorder in Nigeria. Treatment of epilepsy is long-term and sometimes lifelong with anti-seizure medications. There are conflicting reports on the effect of anti-seizure medications on serum folate. There is therefore a need to determine the effect of a commonly used anti-seizure medication's on serum folate levels of children. This would provide an evidence-based consideration for folic acid supplementation in children on anti-seizure medication as has been suggested by some studies. Study objectives: To determine whether serum folate levels were lower in children taking long-term carbamazepine or sodium valproate, compared to a control group. Methods: Serum folic acid levels were measured from well-nourished children between the ages of 1–17 years on carbamazepine and sodium valproate monotherapy and their age/sex-matched controls, using spectrophotometry. Results: The mean serum folate levels of patients on carbamazepine (43) and sodium valproate (22) were 0.032 mg/l ± 0.009 and 0.028 mg/l  ±  0.008, respectively. The mean folate levels of the controls were 0.046 mg/l  ±  0.03 ( p = 0 001). No statistically significant difference was observed between the serum folate levels of children on the two anti-seizure medications, that is, carbamazepine and valproate. Conclusion: The children on treatment with carbamazepine and sodium valproate for more than 6 months had statistically significantly lower serum levels of folic acid compared to the standard reference range and controls. The serum folate levels of children on carbamazepine were not statistically different from those on sodium valproate.
