Cellular Internalization and Biocompatibility of Periodic Mesoporous Organosilica Nanoparticles with Tunable Morphologies: From Nanospheres to Nanowires
Authors: Fatieiev Yevhen , Croissant Jonas G. , Alamoudi Kholod , Khashab Niveen M. 
Published: January 2017

AbstractThis work describes the sol–gel syntheses of para‐substituted phenylene‐bridged periodic mesoporous organosilica (PMO) nanoparticles (NPs) with tunable morphologies ranging from nanowires to nanospheres. The findings show the key role of the addition of organic co‐solvents in the aqueous templates on the final morphologies of PMO NPs. Other factors such as the temperature, the stirring speed, and the amount of organic solvents also influence the shape of PMO NPs. The tuning of the shape of the PMO nanomaterials made it possible to study the influence of the particle morphology on the cellular internalization and biocompatibility.
A tractable analytical model for interference characterization and minimum distance enforcement to reuse resources in three‐dimensional in‐building dense small cell networks
Authors: Saha Rony Kumer , Aswakul Chaodit 
Published: January 2017

SummaryIn this paper, we address mainly 2 important issues, namely, characterizing co‐channel interference and enforcing a minimum distance between femtocell base stations (FCBSs) for reusing resources in FCBSs deployed in a 3‐dimentional multi‐floor building. Each floor is modeled as a group of square‐grid apartments, with one FCBS per apartment. We propose a simple yet reasonable analytical model by using planar‐Wyner model for intra‐floor interference and linear‐Wyner model for inter‐floor interference modeling in a 3‐dimensional multi‐floor building to derive a minimum distance between co‐channel FCBSs for optimization constraints, namely, link level interference, spectral efficiency, and capacity. As opposed to orthogonal resource reuse and allocation (ORRA) where resources are reused once, using the proposed model, we develop 2 strategies for reusing resources more than once, that is, non‐ORRA, within a multi‐floor building. An algorithm of the proposed model is developed by including an application of the model to an ultra‐dense deployment of multi‐floor buildings. With an extensive numerical analysis and system level simulation, we demonstrate the capacity outperformance of non‐ORRA over ORRA by manifold. Further, with a fairly accurate yet realistic estimation, we show that the expected spectral efficiency of fifth‐generation networks can be achieved by applying the proposed model to an ultra‐dense deployment of FCBSs.

Published: January 2017

Light effect on cultures of microalgae has been studied mainly on single species cultures. Cyanobacteria have photosynthetic pigments that can capture photons of wavelengths not available to chlorophylls. A native Louisiana microalgae (Chlorella vulgaris) and cyanobacteria (Leptolyngbya sp.) co‐culture was used to study the effects of light quality (blue–467 nm, green–522 nm, red–640 nm and white–narrow peak at 450 nm and a broad range with a peak at 550 nm) at two irradiance levels (80 and 400 μmol m−2 s−1) on the growth, species composition, biomass productivity, lipid content and chlorophyll‐a production. The co‐culture shifted from a microalgae dominant culture to a cyanobacteria culture at 80 μmol m−2 s−1. The highest growth for the cyanobacteria was observed at 80 μmol μmol m−2 s−1 and for the microalgae at 400 μmol m−2 s−1. Red light at 400 μmol m−2 s−1 had the highest growth rate (0.41 d−1), biomass (913 mg L−1) and biomass productivity (95 mg L−1 d−1). Lipid content was similar between all light colors. Green light had the highest chlorophyll‐a content (1649 μg/L). These results can be used to control the species composition of mixed cultures while maintaining their productivity.

(Dept. of Physiology & Biophysics, School of Medicine, University of Chile, Santiago, and Dept. of Obstetrics & Gynecology, Hospital Sotero del Rio, Puente Alto, Chile, and International Fertility Research Program, Research Triangle Park, North Carolina 27709, USA). The clinical efficacy of the repeated transcervical instillation of quinacrine for female sterilization.Int J Gynaecol Obstet 14:499–502, 1976.The safety and efficacy of the repeated transcervical instillation of quinacrine hydrochloride in a suspension of 5 ml of 2% Xylocaine was evaluated in 200 patients. All instillation procedures were performed during the proliferative phase of the menstrual cycle: the second instillation was made in the first menstrual cycle following the initial instillation and the third and last instillation at 6 months after the first. None of the patients used any adjunctive contraceptives. Follow‐up visits were scheduled at 6‐month intervals after the last instillation. The potentially serious complications following the instillation were four cases of cortical exitation, and one case of acute adnexitis. The second instillation was not performed for 16.0% and the third instillation was not performed for 16.7% of the patients, for medical and/or personal reasons. Fifty‐one pregnancies were reported, 41 (80.4%) before completion of the three instillations. The results of this study show that the instillation schedule used is unsatisfactory for widespread use. Additional studies are currently being conducted to evaluate the use of an adjunctive contraceptive up to the time of the third instillation in order to reduce the high pregnancy rate.

Szoke, B. and Kiss, D. (Dept. of Obstetrics and Gynaecology, Municipal Hospital, Dunaujváros, Hungary). The use of the ultrasonic echo technique in examining the normal and pathological involution in the puerperium.Int J Gynaecol Obstet 14: 513–516, 1976.The involution of the uterus in the puerperium was investigated after 50 normal, and 15 pathological pregnancies. By means of daily performed ultrasonic examinations the size and location of the uterus can be well determined, and the pace of the involution as well as the existing subinvolution can be diagnosed. It was found that in multiparas and in cases of uterine malformations the pace of the involution is somewhat slower, while in premature deliveries it is faster. By the help of this harmless and repeatable diagnostic technique the puerperal complications can be recognized and thus prevented.

Published: January 2017

ABSTRACTAmniotic fluid, maternal and cord serum IgD determinations were performed in 30 healthy pregnant women during labor. Immunoglobulin D was determined by simple radial immunodiffusion by using low concentration immunoplates. Maternal serum IgD mean level amounted to 4.39 mg/100 ml, while in fetal serum and amniotic fluid no immunoglobulin D was detected in any of the cases presented. The absence of IgD in the amniotic fluid supports the view of a special mechanism which exerts selective inhibition of its passage into the amniotic cavity.
The Pregnant Couple
Authors: Shane Rachel , Linn Margaret W. 
Published: January 2017

ABSTRACTAlthough the husband's reactions to and feelings about his wife's pregnancy are frequently overlooked, his wife is always concerned about his perception of her. She often feels unattractive and is most interested in how satisfied her husband is with her pregnant body. The present study attempts to determine whether the husband or wife viewed the wife's body more positively, whether the husbands and wives could accurately predict each other's satisfaction or dissatisfaction with the pregnant body, and whether husbands' and wives' attitudes about important perinatal issues differed significantly. The data were analyzed by multivariate analysis of variance, comparing the husbands' and wives' satisfaction or dissatisfaction with the pregnant body. The body cathexis scale was used to measure such satisfaction and Osgood's semantic differential measured attitudes toward “pregnancy”, “spouse”, “unborn baby”, and “labor and delivery”. Findings show that husbands were more satisfied with their wives' pregnant bodies than the wives themselves were. The wives were not able to predict their husbands' levels of satisfaction, although the men accurately predicted their wives' responses. Husbands also tended to hold more positive attitudes toward perinatal issues.

Published: January 2017

ABSTRACTTwo devices designed for rapid assay of urinary estriol, the E3KIT and the E3HAIR KIT, were evaluated using urine samples taken from pregnant women. Additionally, the clinical application of these devices in pregnancy management was examined. Correlations were high between an established method and the E3KIT method (r=0.819, p<0.001) and between the E3HAIR KIT method and the E3KIT method (r=0.936, p<0.01). E3HAIR KIT assays showing E3values of less than 20 μg/ml (positive at 100‐fold dilution of the urine) after the 36th week of pregnancy suggested fetoplacental dysfunction and indicated that more detailed tests were required. The E3KIT, which provided rapid quantitative assay of urinary estriol, was capable of measuring 10 samples in approximately 3 hours. The E3HAIR KIT provided semiquantitative assays of 10 samples in 2 hours. The speed, simplicity, and accuracy of the E3HAIR KIT indicates its high clinical value as a prospective large‐scale screening method for fetoplacental function.

Published: January 2017

ABSTRACTA study was undertaken to look at the clinical behavior of the Dalkon Shield, the Lippes Loop D and the TCu‐200 inserted by physicians and midwives. Differences among the three devices were not statistically significant, although lower expulsion rates and higher pregnancy rates were reported for the Dalkon Shield. No differences were observed between insertions performed by physicians and those performed by midwives; this emphasizes the efficiency of using paramedical personnel in the field of intrauterine contraception.
Consumption Coagulopathy Associated With Intrauterine Fetal Death: The Role of Heparin Therapy
Authors: Strauss John H. , Ballard James O. , Chamlian Dikran 
Published: January 2017

ABSTRACTA gravida with intrauterine fetal death who developed progressive chronic consumption coagulopathy was treated with heparin. When serial fibrinogen levels fell below 100 mg% and the prothrombin time was significantly prolonged, intravenously injected heparin corrected hypofibrinogenemia. A safe delivery followed administration of oxytocin. The authors emphasize the infrequent need for heparin therapy in the majority of cases of the intrauterine fetal death syndrome. Therapeutic guidelines for its use in selected cases are reviewed.
Histologic Malignancy Grading in Invasive Squamous Cell Carcinoma of the Vulva
Authors: Kabulski Z. , Frankman O. 
Published: January 2017

ABSTRACTA preliminary report on a histologic malignancy grading of vulvar carcinoma is presented. A retrospective histologic study of 40 vulvar carcinoma cases stage I and II (TNM‐system) with a minimum five‐year follow‐up was carried out and correlated to the course of the disease. Morphologic criteria characterizing the tumor cell population, as well as the tumor‐host relationship, were examined and scored. The scores obtained could be divided into three groups that correlated well with the clinical outcome. The low‐score group had no metastases or recurrence, whereas 82% of the high‐score group had both metastases and fatalities. Depth of invasion was found to have a strong correlation to clinical outcome. A more accurate morphologic malignancy grading of such carcinomas could lead to a more individual and often less radical treatment plan.
The Use of Paramedics in Family Planning Services in Iran
Authors: Ghorbani F. S. 
Published: January 2017

ABSTRACTIn the Family Planning Department of Farah Maternity Hospital, from 1968 to 1976, paramedics were trained to administer all reversible methods of family planning and pregnancy termination up to ten weeks and to perform a limited number of abdominal and vaginal tubectomies (1). From 1974 to 1976, all the above methods, except tubal ligation, were performed satisfactorily on 460 417 acceptors at a clinic not located in the hospital. The complication rate of 1%–5% was the same whether the procedures were performed by paramedics or by physicians. The project has been economical. It has been accepted by both patients and paramedics and has freed doctors to carry out other work.

Published: January 2017

ABSTRACTHigh dose progestogen was used to treat 112 cases of primary sterility due to uterotubal block, after tuberculosis and cornual myomata were excluded as causes of the condition. The duration of sterility ranged from three to 18 years. Patients were treated for six or 12 months, depending on their responses to the drug. The results of treatment were very favorable; bilateral and unilateral patency was achieved in 74.0% and 11.6% of the patients, respectively. Pregnancy occurred in 42.8% of all cases studied.
The Value of Simple Tests in the Detection of Human Ovulation
Authors: Lotan Y. , Diamant Y. Z. 
Published: January 2017

ABSTRACTCervical mucus viscosity (CMV) and fern test (FT), leukocyte alkaline phosphatase (LAP) activity, basal body temperature (BBT) and serum luteinizing hormone (LH) levels were determined during 31 normal menstrual cycles of 29 volunteers. The day of the serum LH surge was taken as a reference point in evaluating the reliability and sensitivity in predicting ovulation of the other tests studied. Serum LH surge was accompanied by a sudden decrease in CMV, an increase in LAP activity, a gradual increase in FT and biphasic changes of BBT. In about 95% of cycles studied, the lowest values of CMV and peak values of LAP activity appeared on the day of the serum LH surge or one day before or one day after. The lowest point of the BBT coincided with the LH surge in only 26% of cycles. In 53% of cycles, the span was greater than one day before or after the LH peak. The FT corresponded to the LH surge in only 33% of the cycles, while in an additional 33% the preovulatory FT response occurred more than one day before or after the LH surge. The results indicate that CMV and LAP tests are rapid, simple and reliable for monitoring follicular maturation and the timing of ovulation when carried out daily, and may be of value in monitoring treatment during the induction of ovulation.
Medical Termination of Pregnancy: Public Opinion in an Urban Population
Authors: Charles S. X. , Charles Vimala 
Published: January 2017

ABSTRACTThe influence of religion, education and socioeconomic status on opinion regarding medical termination of pregnancy were examined. A random sample of 514 married, urban women was selected. The study revealed that religion, education and economic status influenced the formation of opinion regarding pregnancy termination. The women gave many reasons for considering it beneficial. The most common reasons were that pregnancy termination offered increased opportunities for better education and nutrition. The limitation of family size and elimination of unwanted pregnancies were also noted as needs of the community.

Published: January 2017

ABSTRACTA case of antepartum fetal arrhythmia is reported. The diagnosis of atrial premature beats was confirmed during labor by simultaneous recording of fetal heart rate and fetal electrocardiogram. The possibility of fetal distress during labor was excluded by fetal heart rate and acid‐base monitoring. The difficulty of reaching a definitive antepartum diagnosis of the arrhythmia and its significance in relation to fetal well‐being are discussed.
Condylomatous Epithelial Changes in the Uterine Cervix and Their Relationship to Cervical Carcinogenesis
Authors: Syrjänen Kari J. 
Published: January 2017

ABSTRACTTwo hundred twenty‐six (226) women with histologically verified dysplastic or neoplastic epithelial lesions in the uterine cervix were assessed for the presence (CO‐series) or absence (N‐CO‐series) of the three newly established types of condylomatous lesions. Both the CO‐series and the N‐CO‐series comprised 113 patients. Histologic changes fulfilling the previously outlined criteria of the (a) flat, (b) inverted and (c) papillomatous condylomas were found in association with all degrees of epithelial atypia, from mild dysplasia to frankly invasive carcinoma. The flat type was most common, comprising 69% of all condylomas. The inverted and papillomatous types were relatively rare, with frequencies of 18.6% and 12.4%, respectively. The mean age of the patients in the CO‐series was 30.9 years, that of the N‐CO‐series patients was 39.3 years (p < 0.0001). The causal relationship between the cervical condylomas and cervical carcinoma is discussed. The conclusion is drawn that this possibility needs to be seriously considered when searching for a venereally transmitted agent as an etiologic factor of cervical carcinoma.

The Tunisian Experience in Legal Abortion
Authors: Nazer Isam 
Published: January 2017

ABSTRACTIn 1965, Tunisia became the first Moslem country to liberalize abortion laws. This paper is a review of Tunisia's experience and is, therefore, significant to other Moslem countries. The experience is also of interest to the developing world, as it demonstrates that such liberalization does not lead to excessive use or abuse of abortion, nor does it burden hospital services. The study shows, a first for a developing country, that liberalization of abortion can improve contraceptive practice.
Prostaglandin F Production by Tissue Expiants from Term Pregnancies
Authors: Lackritz Richard , Cohen Wayne R. , Tulchinsky Dan 
Published: January 2017

ABSTRACTExplants of various tissues obtained from pregnant women at term and from nonpregnant women were maintained in culture and their capacities to synthesize prostaglandin (PGF) were evaluated. Myometrial and decidual tissues from pregnant women produced significantly smaller amounts of PGF than those from nonpregnant women, suggesting that PGF production is inhibited during gestation. Decidual PGF synthesis was also inhibited by the addition of progesterone, estradiol or indomethacin. The PGF synthesis of the chorion of women in labor was lower than that of women not in labor. In the latter group, the chorion, decidua and myometrium produced significant amounts of PGF, but amniotic PGF production was negligible. Our findings show that the decidua and chorion, as well as the myometrium, are potentially important sources of PGF production. PGF synthesis during pregnancy also may be affected by local inhibitory influences.
Prostaglandin Production by Rhesus Monkey Corpora Lutea in Vitro: Effects of Estrogen Administration
Authors: Balmaceda Jose P. , Valenzuela Guillermo V. , Eddy Carlton A. , Asch Ricardo H. 
Published: January 2017

ABSTRACTLuteolysis was induced in normal cycling rhesus monkeys (Macaca mulatta) by daily administration of estradiol cypionate (50 μg/kg) from day 1 to 7 postovulatory (controls received vehicle). Luteectomy was performed after treatment, using microsurgical techniques and minimal manipulation. Serum progesterone concentrations did not demonstrate characteristic luteal rise in estrogen‐treated animals as compared to controls. Estrogen treatment increased prostaglandin F2α/ E ratio produced in vitro by the corpora lutea twofold compared to controls. These results support our previous observations that luteolysis in the rhesus monkey is associated with increased production of prostaglandin F2α and decreased production of prostaglandin E by the corpus luteum.

Published: January 2017

ABSTRACTUse of the sutured Lippes Loop for immediate postpartum insertion was evaluated in 100 volunteers at the Kasr‐el‐Aini Hospital in Cairo. The intrauterine devices were inserted manually immediately after delivery of the placenta. There was an expulsion rate of 1.2 per 100 women at three months, one case of infection requiring treatment and one removal because of bleeding. One woman became pregnant and expelled the Loop. The two major problems associated with the use of an intrauterine device, high expulsion rate and perforation, were overcome by hand insertion of the Loop.
