Abstract
RESEARCH QUESTION Are there differences in the frequency of gestational diabetes between women of self-defined refugee status (SDRS), immigrant women, and women born in Germany? Does the perinatal data of women with gestational diabetes (GDM) differ depending on the migration status? METHOD For the Pregnancy and Obstetric Care for Refugees (ProRef) study between June 2020 and April 2022, data was collected with the Migrant Friendly Maternity Care Questionnaire (MFMCQ) among women on the postpartum ward in three perinatal centers in Berlin. The data concerning GDM was statistically analyzed. RESULTS Women of SDRS were tested for GDM (3.2%, p=0.0025) significantly less often than immigrant women (1.4%) or women born in Germany (0.6%). The rate of GDM was higher among immigrant women (19.6%, p=0.001) than among women born in Germany (15.0%) and women of SDRS (14.1%). The rate of GDM varied depending on the country of origin. Vietnam (OR 3.41) and Turkey (OR 2.18) as countries of origin, corrected for age and body mass index, increased the chance of gestational diabetes. The perinatal outcome data among women with GDM did not differ depending on the migration status. CONCLUSION As women of SDRS are tested for GDM less frequently, this potentially suggests a supply gap in the health care system. However, the perinatal outcome data does not differ for women of SDRS.

The impact of regional origin on the incidence of gestational diabetes mellitus in a multiethnic European cohort. Front Public Health 2024; 11:1286056. [PMID: 38312137 PMCID: PMC10834617 DOI: 10.3389/fpubh.2023.1286056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 12/28/2023] [Indexed: 02/06/2024] Open
Abstract
Introduction Women with migration background present specific challenges related to risk stratification and care of gestational diabetes mellitus (GDM). Therefore, this study aims to investigate the role of ethnic origin on the risk of developing GDM in a multiethnic European cohort. Methods Pregnant women were included at a median gestational age of 12.9 weeks and assigned to the geographical regions of origin: Caucasian Europe (n = 731), Middle East and North Africa countries (MENA, n = 195), Asia (n = 127) and Sub-Saharan Africa (SSA, n = 48). At the time of recruitment maternal characteristics, glucometabolic parameters and dietary habits were assessed. An oral glucose tolerance test was performed in mid-gestation for GDM diagnosis. Results Mothers with Caucasian ancestry were older and had higher blood pressure and an adverse lipoprotein profile as compared to non-Caucasian mothers, whereas non-Caucasian women (especially those from MENA countries) had a higher BMI and were more insulin resistant. Moreover, we found distinct dietary habits. Non-Caucasian mothers, especially those from MENA and Asian countries, had increased incidence of GDM as compared to the Caucasian population (OR 1.87, 95%CI 1.40 to 2.52, p < 0.001). Early gestational fasting glucose and insulin sensitivity were consistent risk factors across different ethnic populations, however, pregestational BMI was of particular importance in Asian mothers. Discussion Prevalence of GDM was higher among women from MENA and Asian countries, who already showed adverse glucometabolic profiles at early gestation. Fasting glucose and early gestational insulin resistance (as well as higher BMI in women from Asia) were identified as important risk factors in Caucasian and non-Caucasian patients.

Equal Alternatives or Lower Standards for Immigrant Women-Analyzing Obstetric Care for Immigrant Women in Berlin Within the Framework of Cultural Health Capital. J Racial Ethn Health Disparities 2023:10.1007/s40615-023-01732-0. [PMID: 37581765 DOI: 10.1007/s40615-023-01732-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 07/19/2023] [Accepted: 07/21/2023] [Indexed: 08/16/2023]
Abstract
In obstetric clinics in Berlin, Germany, more than half of the women are immigrants. The main objective of the qualitative study was to explore the staff's experiences with obstetric care for immigrants and juxtapose it with the immigrants' comments on their birth experiences. We analyze potential differences along the framework of a cultural health capital (CHC). Between May and August 2017, semi-structured interviews were carried out with 17 obstetricians and 17 midwives at four obstetric clinics in Berlin. The verbally transcribed interview material was subjected to a qualitative content analysis according to Mayring. Furthermore, a secondary data from an interview study was analyzed in the purpose of providing some insight into the practitioner study participant perspective. Between January and May 2017, in the postpartum ward at the Berlin Charité Campus Virchow Clinic, an interview study guided by the migrant-friendly maternity care questionnaire was conducted among 410 migrant and non-migrant women. For this study, the free-text comments on the pregnancy care were analyzed. The staff interviewees identified language barrier and legal status as risk factors for the late onset of obstetric care. CHC functioning potentially as alternatives to the established health care structures were voiced. Strong family ties among immigrant families bear a high potential for support. Gratefulness was voiced by the staff and immigrant patients as a source of satisfaction with care. Our study shows that obstetric care for immigrant women remains a challenge. CHC of immigrant women might partially compensate for exclusion.

Abstract
Research Question What are the growth patterns of uterine myomas in untreated premenopausal women? Which factors influence the growth rate of uterine myomas in premenopausal women? Method All premenopausal women who presented to the outpatient myoma consultation clinic between January 2005 and March 2022 at least twice were screened. Exclusion criteria were hormonal therapy, pregnancy, and postmenopausal status. Results A total of 189 patients were included in our study which focused on the respective largest uterine myoma of each woman. An ideal linear growth over time was assumed. Most myomas (82%) increased in size. The mean annual growth of these myomas was 68.42 cm 3 . The most important prognostic factor for growth was the initial size of the myoma. The absolute annual growth of myomas measuring > 50 cm 3 at first presentation was higher compared to smaller myomas (p < 0.001). The relative annual growth rate was highest for myomas measuring between 20 and 50 cm 3 at the initial presentation (p = 0.003). The relative annual growth rate in women older than 40 years was significantly lower than that in women below the age of 40 years (p = 0.003). Conclusion Overall, it is difficult to make an individual prognosis about the growth pattern of a uterine myoma in a specific patient. It should be noted especially in asymptomatic patients that spontaneous regression of myoma size can also occur in premenopausal women.

Reasons for a Lower Rate of Epidural Anesthesia During Birth for Immigrant Women in the Eyes of Medical Staff: A Mixed-Methods Analysis. J Immigr Minor Health 2022; 24:1501-1507. [PMID: 35389132 DOI: 10.1007/s10903-022-01357-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/16/2022] [Indexed: 11/26/2022]
Abstract
Various studies have shown that immigrant women in comparison to non-immigrant women of the same parity have lower rates of epidural anesthesia (EDA). Data from two studies on immigrant obstetric care in Berlin, Germany were analyzed to answer the following question: What reasons do the medical staff see for the lower rate of EDA in immigrant women? Between May and August 2017, 34 interviews with obstetricians and midwives in four obstetric clinics in Berlin were conducted on the topic of obstetric care for immigrant women. After anonymizing the more than 20 h of interview material, transcripts were coded with MaxQDa and analyzed according to the qualitative content analysis.The quantitative data is from an online survey conducted between May and October 2017, in all but one obstetric clinic in Berlin with obstetricians and midwives. Regarding the research question, 121 questionnaires could be analyzed. In the online survey, (multiple answers were possible), the top reason for a lower rate of EDA given was mostly fear on the part of the immigrant women (64%). A language barrier, which results in logistic and time constrictions, is mentioned as the second most frequent reason (50%). The explorative analysis of the interviews shows that doctors and midwives regard cultural aspects such as different expectations on the birth experience as a reason for a lower EDA rate. Furthermore, within the medical staff the impression persists that in some cases the companion decides on the behalf of the patient about the application of an EDA, which from time to time is against the wish of the immigrant woman giving birth. In the view of the medical staff, the reasons for a lower rate of EDA during birth for immigrant women were varied. On one side, this is attributed to the wishes of the respective women ("demand") but on the other side this can be attributed to the health care system ("supply"). In the case of a language barrier, the "supply" and the access of EDA for immigrant women is limited and can be then shifted to the German-speaking companion to make a decision regarding EDA ("structural deprivation of self-determination").

Abstract
INTRODUCTION Violence against medical staff is a known problem in emergency departments. Nevertheless, there is little empirical data about physical and verbal violence against staff members in delivery rooms in Germany. METHODS This study comprises both quantitative and qualitative analyses. For the quantitative part, midwives and doctors working in delivery rooms in Berlin were asked to fill out a questionnaire about their experiences with violence within the last 6 months; this survey was completed between 15 November 2019 and 15 February 2020. For the qualitative part, structured interviews were conducted to investigate individual experiences of violence in more detail. RESULTS Out of 173 participants in total, 148 (86%) reported to have experienced verbal violence and 82 (47%) reported to have experienced physical violence. Midwives and younger staff seem to be more often affected by violence. 70% of the participants did not feel sufficiently prepared for situations of violence. In a total of 36 interviews, the participants specifically named communicative problems, too high expectations of the pregnant women and their companion, as well as language barrier and cultural differences as reasons for furthering violence. CONCLUSION Violence against staff is a relevant problem in delivery rooms in Berlin. Participants would welcome training to deal with violence and professional help for coming to terms with experiences of violence. Improved information about pregnancy and delivery, institutionalized translation, and more staff could possibly help to decrease frequency of violence.

Abstract
Background Migrant women may have an increased risk of adverse birth outcomes. This study analyses the occurrence of low birth weight, preterm birth and intrauterine growth restriction / fetal growth restriction (IUGR/FGR) in pregnant migrants. Method Cross-sectional study of 82 mother-child pairs of pregnant migrants attending medical care in Germany. Results The Median age was 27 years, 49% of patients were of oriental-asian ethnicity and median year of migration was 2015. At least one previous pregnancy was reported in 76% of patients, in 40% the delivery mode was caesarian section. Median gestational age was 39.7 weeks. Preterm birth occurred in 6.1% of pregnancies. Median gestational age for preterm birth was 32.3 weeks. Low birth weight (< 2500 g) occurred in 6.1%. Birth weights below the 10th percentile of birth weight for gestational age were observed in 8.5% of the total cohort. Conclusions Compared to German data no increased occurrence of low birth weight, preterm birth or IUGR/FGR was found. We note that the rate of caesarian section births was higher than in the general population for reasons yet to be identified. The authors propose stratification according to migration status for the national documentation of birth outcomes in Germany.

Abstract
Purpose To determine the frequency of fetal infection as well as adverse pregnancy outcomes following antenatal hyperimmunoglobulin (HIG) treatment for primary cytomegalovirus (CMV) infection in pregnancy. Methods In our observational cohort study, data from 46 women with a primary CMV infection during pregnancy were evaluated. Primary CMV infection was defined by seroconversion or the presence of CMV-IgM and low CMV-IgG avidity. All women received at least two or more infusions of HIG treatment (200 IU/kg). Congenital CMV infection (cCMV) was diagnosed by detection of CMV in amniotic fluid and/or neonatal urine. We compared the rate of maternal–fetal transmission from our cohort to data without treatment in the literature. The frequency of adverse pregnancy outcomes was compared to those of live-born infants delivered in our clinic. Results We detected 11 intrauterine infections in our cohort, which correlates to a transmission rate of 23.9%. Compared to the transmission rate found in cases without treatment (39.9%), this is a significant reduction (P = 0.026). There were no adverse pregnancy outcomes in our cohort. The mean gestational age at delivery was 39 weeks gestation in treatment and control group. Conclusion The administration of HIG for prevention of maternal–fetal CMV transmission during pregnancy seems safe and effective.

The influence of migration on women's use of different aspects of maternity care in the German health care system: Secondary analysis of a comparative prospective study with the Migrant Friendly Maternity Care Questionnaire (MFMCQ). Birth 2020; 47:39-48. [PMID: 31854011 DOI: 10.1111/birt.12476] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 11/22/2019] [Accepted: 11/26/2019] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Approximately 21% of Germany's inhabitants or their parents have been born abroad. There is evidence that immigrant women are starting antenatal care later than nonimmigrants. In Berlin, equality in health care access had improved until 2011-2012, leaving only women with Low German language proficiency and an insecure residence status particularly at risk. With the recent influx of refugees, we analyzed whether access to antenatal and postpartum care differs depending on immigration, residence status, income, and education. METHODS At our Berlin tertiary care center, a modified version of the Migrant Friendly Maternity Care Questionnaire was administered to women who delivered in the first half of 2017. Multivariate modeling compared nonimmigrant women, immigrants, and women who are direct descendants of immigrants. RESULTS The study included 184 nonimmigrant women, 214 immigrant women, and 62 direct descendants of immigrants. Germany is relatively good in prenatal care for immigrant women, as most are getting adequate prenatal care. However, 21% of immigrants compared with 11% of nonimmigrant women started pregnancy care after the first trimester (P = .03). Low income was a more powerful predictor than immigration status for starting prenatal care after the first trimester. Immigrant women (23%) were less informed on postpartum care availability than nonimmigrants (3%) and used less postpartum midwifery care. CONCLUSIONS When designing health care interventions for immigrant women, not only migration-specific factors should be considered but also low income as a barrier to access to maternity care.

Safety of tenofovir during pregnancy: early growth outcomes and hematologic side effects in HIV-exposed uninfected infants. Eur J Pediatr 2020; 179:99-109.

Abstract
Intrauterine exposure to zidovudine-based combination antiretroviral therapy (cART) can cause severe anemia within the first weeks of life. Tenofovir disoproxil fumarate (TDF)-based regimens may have less hematologic side effects but may affect growth parameters. This study aimed to assess the safety of TDF for prevention of mother-to-child transmission (PMTCT) in HIV-exposed uninfected infants regarding early growth outcomes and hematologic side effects. Our retrospective observational cohort study included children born (n = 232) to HIV-infected mothers (n = 228) on cART. Blood counts were compared at birth, 4-6 weeks, and 3, 12 and 18 months of age. Growth parameters were measured at birth and 12 and 18 months of age. Data were analyzed according to treatment group (TDF and non-TDF cART regimes). The median hemoglobin (Hgb) was significantly lower in the non-TDF-based group at birth (15.4 g/dl vs. 16.9 g/dl; **p = 0.002) and at 4-6 weeks of age (9.9 g/dl vs. 10.4 g/dl; **p = 0.004). The mean corpuscular volume was higher in the non-TDF-based group (109 fl vs. 105 fl; ***p < 0.001) as well at 4-6 weeks (102 fl vs. 95 fl; ***p < 0.001). In the TDF-based group, a higher proportion of neutropenia (grade 2 and higher) compared to the non-TDF-group (21.4% vs. 11%; *p = 0.015) was observed at three months of age. This effect was transient. There was no difference in growth.Conclusions: TDF appears to have no major side effects in our cohort. Transient anemia was observed more commonly with non-TDF regimens. However, our research suggests a potential delayed effect of TDF on neutrophils at 3 months of age.What is Known:• TDF is suspected to affect the growth of HIV-exposed uninfected infants.• Non-TDF-based cART regimes for prevention of mother-to-child transmission of HIV often result in transient anemia in the infant.What is New:• TDF appears to have no major side effects regarding the growth of HIV-exposed uninfected infants.• Our research suggests a potential delayed effect of TDF on neutrophils at 3 months of age in these infants.

Abstract
INTRODUCTION Approximately 21% of Germany's inhabitants have been born abroad or are of direct descent of immigrants. A positive birth experience has an effect on a woman's mental health and her future family planning choices. While international studies showed that immigrant women are less satisfied with their birth experience, no such study has been conducted in Germany until now. METHODS At our center of tertiary care in Berlin, with approximately 50% immigrants among patients, pregnant women of at least 18 years of age were offered participation in this study. A modified version of the Migrant Friendly Maternity Care Questionnaire (MFMCQ) designed by Gagnon et al. in German, English, French, Spanish, Arabic and Turkish was used. We compared non-immigrant women to immigrant women and women with direct descent of immigrants. For certain analysis, the latter two groups were included together under the category "migration background". RESULTS During the study period, 184 non-immigrant, 214 immigrant women and 62 direct descendants of immigrants were included. The most frequent countries of origin were Syria (19%), Turkey (17%), and Lebanon (9%). We found a slight difference between groups regarding age (non-immigrants: mean 33 years versus women with any migration background: mean 31) as well as parity with more non-immigrants delivering their first child. No difference in the satisfaction with care was observed between immigrant and any migration background groups (p ≥ 0.093 in the two-sided Fisher's exact test). At least 75.8% of all participating women reported complete satisfaction with care during labor, birth and after birth. Interestingly, the level of German language proficiency did not influence the immigrant patient's satisfaction with care. CONCLUSION The study results show no difference regarding overall satisfaction with care during labor and birth despite a relevant language barrier. We are for the first time providing the MFMCQ in German and Turkish. Further future analyses on the impact of patient expectations on satisfaction with care will be conducted.

Abstract
INTRODUCTION Postpartum or peripartum hemorrhage (PPH) is a major cause of maternal death worldwide. Fertility preserving second stage interventions following uterotonic medications may include compression sutures, uterine balloon tamponade and ligation or embolization of arteries. PRESENTATION OF CASE We present a case of PPH where a novel "uterine sandwich" approach (combination of chitosan-covered gauze with intrauterine balloon tamponade) was effectively used to stop further blood loss and prevented more invasive second stage interventions. Furthermore, we present the ultrasonographic image of chitosan-covered gauze in the uterine cavity. DISCUSSION Chitosan-covered gauze and intrauterine balloon tamponade are complementary in their mechanism of work, the balloon reducing blood flow into the uterus and the chitosan-covered gauze enhancing the coagulation. CONCLUSION This novel "uterine sandwich" approach can be a useful method for fertility preserving management of PPH.

Abstract
Abstract
Introduction
Postpartum or peripartum hemorrhage (PPH) is a major cause of maternal death in Western industrialized countries. Fertility preserving second stage interventions following uterotonic drugs include embolization or ligation of relevant arteries, uterine tamponade or compression sutures. Little is known about the complications due to uterine compression sutures. We describe a case report in association with uterine compression sutures and provide a systematic review on necrosis due to compression sutures (CSU).
Data sources
A PubMed database search was done up to October 1, 2016 without any restrictions of publication date or journal, using the following key words: “compression suture” and “postpartum hemorrhage” or “peripartum hemorrhage”. Reported cases were considered eligible when reason for postpartum hemorrhage (PPH), type of compression suture, suture material and type of complication were described.
Results
Among 199 publications a total of 11 reported on uterus necrosis after CSU applied for PPH. B-Lynch and modifications were applied in seven cases, Cho compression sutures in three cases and in one case B-Lynch and Cho techniques were combined. In six cases no additional measures were applied, in two cases vessel ligation, in one case embolization and in one case intrauterine balloon application were applied. In one case of partial necrosis it is not reported if additional measures were applied.
Discussion and conclusion
Uterine compression sutures are a useful method for fertility preserving management of postpartum hemorrhage. The risk of serious complications demands the careful consideration of its use. More research is necessary to improve the technique.

Characterisation of triterpenes and new phenolic lipids in Cameroonian propolis. PHYTOCHEMISTRY 2014; 106:156-163.

Abstract
Chemical investigation of a sample of propolis originating from North-Western Cameroon led to the isolation of thirteen alk(en)ylphenols (1-13) (inseparable mixture) along with α-amyrin (14), β-amyrin (15), lupeol (16), cycloartenol (17), mangiferonic acid (18), ambonic acid (19), mangiferolic acid (20), ambolic acid (21), isomangiferolic acid (22) and nine alk(en)ylresorcinols (23-31) (inseparable mixture). All compounds were identified following analysis of their spectroscopic data and comparison with previously published reports. Compounds (8), (12), (13) and (30) are new natural products. GC-MS analysis carried out on the alk(en)ylphenol and alk(en)ylresorcinol mixtures (dimethyl disulphide trimethylsilyl derivatives) revealed the presence of saturated and mono-unsaturated compounds with side chain lengths ranging from C11 to C19 and C15 to C19, respectively. The position of the double bond in mono-unsaturated derivatives was established from the characteristic fragments resulting from the cleavage of the bond between the two methylthio-substituted carbons. The most abundant compound in each mixture was 3-(12'Z-heptadecenyl)-phenol (10) and 5-(12'Z-heptadecenyl)-resorcinol (29). This study is the first to report the presence of triterpenes (except for lupeol) and phenolic lipids, including eighteen compounds previously unreported in bee glue, in an African sample.

The dithiol glutaredoxins of african trypanosomes have distinct roles and are closely linked to the unique trypanothione metabolism. J Biol Chem 2010; 285:35224-37.

Abstract
Trypanosoma brucei, the causative agent of African sleeping sickness, possesses two dithiol glutaredoxins (Grx1 and Grx2). Grx1 occurs in the cytosol and catalyzes protein deglutathionylations with k(cat)/K(m)-values of up to 2 × 10(5) M(-1) S(-1). It accelerates the reduction of ribonucleotide reductase by trypanothione although less efficiently than the parasite tryparedoxin and has low insulin disulfide reductase activity. Despite its classical CPYC active site, Grx1 forms dimeric iron-sulfur complexes with GSH, glutathionylspermidine, or trypanothione as non-protein ligands. Thus, contrary to the generally accepted assumption, replacement of the Pro is not a prerequisite for cluster formation. T. brucei Grx2 shows an unusual CQFC active site, and orthologues occur exclusively in trypanosomatids. Grx2 is enriched in mitoplasts, and fractionated digitonin lysis resulted in a co-elution with cytochrome c, suggesting localization in the mitochondrial intermembrane space. Grx2 catalyzes the reduction of insulin disulfide but not of ribonucleotide reductase and exerts deglutathionylation activity 10-fold lower than that of Grx1. RNA interference against Grx2 caused a growth retardation of procyclic cells consistent with an essential role. Grx1 and Grx2 are constitutively expressed with cellular concentrations of about 2 μM and 200 nM, respectively, in both the mammalian bloodstream and insect procyclic forms. Trypanothione reduces the disulfide form of both proteins with apparent rate constants that are 3 orders of magnitude higher than those with glutathione. Grx1 and, less efficiently, also Grx2 catalyze the reduction of GSSG by trypanothione. Thus, the Grxs play exclusive roles in the trypanothione-based thiol redox metabolism of African trypanosomes.

Abstract
Propolis is a widely used natural remedy and a range of biological activities have been attributed to it. The chemical composition of propolis is highly variable and its quality is often controlled on the basis of one or two marker compounds. In order to progress towards a method for the quality control of this complex material, HPLC and 1H-NMR approaches as methods of quality control have been compared. HPLC analyses of 43 samples of propolis were carried out and six marker compounds were quantified in each sample. The same samples were analysed using 1H-NMR and the spectra were then converted into their first derivative forms and digitised using the software application MestRe-C. The digitised data were subjected to principal component analysis using the software application Simca-P. It was found that the chemical composition of propolis mapped well according to the geographical origins of the samples studied when the first three principal components were used to display them. In addition, each sample was assessed for anti-oxidant activity, and the results were then overlaid onto the sample groupings according to 1H-NMR data. It was observed that anti-oxidant properties also mapped quite well according to geographical origin.

Abstract
The aerial parts of Goniothalamus gardneri (Annonaceae) has yielded the known flavonoids 2'-hydroxy-4,4',6'-trimethoxychalcone (flavokawain A), 2',4'-dihydroxy-4,6'-dimethoxydihydrochalcone, 4,2',4'-trihydroxy-6'-methoxydihydrochalcone, 5,7,4'-trimethoxyflavanone (naringenin trimethyl ether) and 7-hydroxy-5,4'-dimethoxyflavanone (tsugafolin) together with three novel compounds, the dimer characterised as (rel)-1beta,2alpha-di-(2,4-dihydroxy-6-methoxybenzoyl)-3beta,4alpha-di-(4-methoxyphenyl)-cyclobutane, 2',4'-dihydroxy-4,6'-dimethoxychalcone and 2'-hydroxy-4,4',6'-trimethoxydihydrochalcone. The last two have previously been synthesised but appear to be new natural products. A similar study of the aerial parts of G. thwaitesii led only to the isolation of the known flavonoids myricetin 4'-O-methyl ether-3-O-alpha-L-rhamnopyranoside (mearnsitrin) and myricetin-3-O-methyl ether (annulatin), together with the triterpenes friedelinol, friedelin and betulinic acid. All compounds were identified by spectroscopic analysis and, for known compounds, by comparison with published data.

Abstract
From the European plant Ballota nigra L. various polyphenols including phenylpropanoid derivatives were isolated. There is increasing evidence that oxidized low-density lipoproteins (Ox-LDL) might be involved in the pathogenesis of atherosclerosis and it has been reported that polyphenols inhibit LDL peroxidation and atherogenesis. The goal of this study was to test whether the major polyphenolic compounds extracted from Ballota nigra, four phenylpropanoid glycosides, verbascoside, forsythoside B, arenarioside, and ballotetroside and one non-glycosidic phenylpropanoid, caffeoyl-L-malic acid, inhibit Cu(2+)-induced LDL peroxidation. The effectiveness of these compounds was compared to the activity of quercetin, a well-known polyphenol inhibitor of Cu(2+)-induced LDL oxidation. Antioxidant efficacious doses (ED 50) of arenarioside and ballotetroside were 1.8 microM and 7.5 microM respectively, while in the same conditions, the ED 50 of forsythoside B and verbascoside were similar (1 microM) and those of quercetin and of caffeoyl-L-malic acid were 2.3 microM and 9.5 microM respectively. Spectrophotometric studies show that quercetin is a Cu(2+) chelator while phenylpropanoid glycosides and caffeoyl-L-malic acid are not Cu(2+) chelators. Therefore, phenylpropanoid glycosides are strong inhibitors of Cu(2+)-induced LDL oxidation, independent of any capacity to act as Cu(2+) chelators.

Abstract
Ballota nigra is a European plant known for its neurosedative properties. In this study, the ability of five phenylpropanoids (verbascoside, forsythoside B, arenarioside, ballotetroside, and caffeoyl malic acid) isolated from a hydroalcoholic extract, to bind to benzodiazepine, dopaminergic, and morphinic receptors was investigated. To carry out these studies, affinity tests with rat striata, entire brains and receptor rich preparations were employed. In addition, the phenolic aspect of these five phenylpropanoid esters led to investigate antioxidant activities using cell-free experiments and cellular experiments including isolated polymorphonuclear neutrophils (PMN). Effects of phenylpropanoid esters against reactive oxygen species as superoxide anion, peroxide hydrogen, hypochlorous acid and hydroxyl radical were tested. These molecules are liberated by PMN during inflammatory disorders, so that reproduction of this process in vitro stimulating PMN by chemical stimulants was undertaken. Results show that four of the five compounds are able to bind to the studied receptors. Inhibitory concentrations at 50% were determined and vary from 0.4 to 4.7 mg/ml. This may be in relation with the Ballota nigra known neurosedative activities. Results concerning antioxidant investigations evidence an ability to scavenge reactive oxygen species. Inhibitory concentrations at 50% obtained are comparable to those of known antioxidant drugs (mesna or N-acetyl cysteine). Moreover, the use of different stimuli having various pathways of action on PMN oxidative metabolism permits to establish that each phenylpropanoid ester has its own particular way of action by using proteine kinase C or phospholipase C pathways.

Abstract
A preliminary survey of the botanical characters of the species Ballota nigra and of its subspecies is reported. Phytochemical investigation of the flowered aerial parts led us to isolation and structural elucidation of one diterpene (13-hydroxyballonigrinolide) and four phenylpropanoid glycosides reported for the first time from the genus Ballota: verbascoside, forsythoside B, arenarioside and ballotetroside. These compounds appear to be characteristic of this species and could be used for the standardization of the drug. Moreover, the four phenylpropanoid glycosides isolated could justify the use of Ballota nigra as a neurosedative drug.
