BackgroundExercise‐based rehabilitation is an important part of treatment patients following coronary artery bypass graft (CABG) surgery.HypothesisTo evaluate effect of very short/short‐term exercise training on cardiopulmonary exercise testing (CPET) parameters.MethodsWe studied 54 consecutive patients with myocardial infarction (MI) treated with CABG surgery referred for rehabilitation. The study population consisted of 50 men and 4 women (age 57.72 ± 7.61 years, left ventricular ejection fraction 55% ± 5.81%), who participated in a 3‐week clinical and 6‐month outpatient cardiac rehabilitation program. The Inpatient program consisted of cycling 7 times/week and daily walking for 45 minutes. The outpatient program consisted mainly of walking 5 times/week for 45 minutes and cycling 3 times/week. All patients performed symptom‐limited CPET on a bicycle ergometer with a ramp protocol of 10 W/minute at the start, for 3 weeks, and for 6 months.ResultsAfter 3 weeks of an exercise‐based cardiac rehabilitation program, exercise tolerance improved as compared to baseline, as well as peak respiratory exchange ratio. Most importantly, peak VO2
(16.35 ± 3.83 vs 17.88 ± 4.25 mL/kg/min, respectively, P < 0.05), peak VCO2
(1.48 ± 0.40 vs 1.68 ± 0.43, respectively, P < 0.05), peak ventilatory exchange (44.52 ± 11.32 vs 52.56 ± 12.37 L/min, respectively, P < 0.05), and peak breathing reserve (52.00% ± 13.73% vs 45.75% ± 14.84%, respectively, P < 0.05) were also improved. The same improvement trend continued after 6 months (respectively, P < 0.001 and P < 0.0001). No major adverse cardiac events were noted during the rehabilitation program.ConclusionsVery short/short‐term exercise training in patients with MI treated with CABG surgery is safe and improves functional capacity.
Anatomical organization of the brain of a diurnal and a nocturnal dung beetle

Published: January 2017

AbstractTo avoid the fierce competition for food, South African ball‐rolling dung beetles carve a piece of dung off a dung‐pile, shape it into a ball and roll it away along a straight line path. For this unidirectional exit from the busy dung pile, at night and day, the beetles use a wide repertoire of celestial compass cues. This robust and relatively easily measurable orientation behavior has made ball‐rolling dung beetles an attractive model organism for the study of the neuroethology behind insect orientation and sensory ecology. Although there is already some knowledge emerging concerning how celestial cues are processed in the dung beetle brain, little is known about its general neural layout. Mapping the neuropils of the dung beetle brain is thus a prerequisite to understand the neuronal network that underlies celestial compass orientation. Here, we describe and compare the brains of a day‐active and a night‐active dung beetle species based on immunostainings against synapsin and serotonin. We also provide 3D reconstructions for all brain areas and many of the fiber bundles in the brain of the day‐active dung beetle. Comparison of neuropil structures between the two dung beetle species revealed differences that reflect adaptations to different light conditions. Altogether, our results provide a reference framework for future studies on the neuroethology of insects in general and dung beetles in particular.

Published: January 2017

AbstractWe report a one‐pot method for the facile synthesis of Cu nanowires in high purity, together with ultrathin diameters well below 20 nm. Selected area electron diffraction and high‐resolution transmission electron microscopy studies confirm that the Cu nanowires are grown along the <110> direction to give pentatwinned, one‐dimensional nanostructures, enclosed by five {100} facets on the side surface. A systematic study further indicates that it is critical to conduct the synthesis under an argon atmosphere in order to improve the purity and uniformity of the nanowires while keeping their diameters thinner than 20 nm. We also demonstrate the use of these nanowires as sacrificial templates for the synthesis of Au‐based nanotubes through a galvanic replacement process.
Mean‐Field Interaction of Brownian Occupation Measures II: A Rigorous Construction of the Pekar Process
Authors: Bolthausen Erwin , König Wolfgang , Mukherjee Chiranjib 
Published: January 2017

AbstractWe consider mean‐field interactions corresponding to Gibbs measures on interacting Brownian paths in three dimensions. The interaction is self‐attractive and is given by a singular Coulomb potential. The logarithmic asymptotics of the partition function for this model were identified in the 1980s by Donsker and Varadhan in terms of the Pekar variational formula, which coincides with the behavior of the partition function of the polaron problem under strong coupling. Based on this, in 1986 Spohn made a heuristic observation that the strong coupling behavior of the polaron path measure, on certain time scales, should resemble a process, named as the Pekar process, whose distribution could somehow be guessed from the limiting asymptotic behavior of the mean‐field measures under interest, whose rigorous analysis remained open. The present paper is devoted to a precise analysis of these mean‐field path measures and convergence of the normalized occupation measures towards an explicit mixture of the maximizers of the Pekar variational problem. This leads to a rigorous construction of the aforementioned Pekar process and hence is a contribution to the understanding of the “mean‐field approximation” of the polaron problem on the level of path measures. The method of our proof is based on the compact large deviation theory developed by Mukherjee and Varadhan in 2016; its extension to the uniform strong metric for the singular Coulomb interaction was carried out by König and Mukherjee in 2015, as well as an idea inspired by a partial path exchange argument appearing in 1997 in work by Bolthausen and Schmock.© 2017 Wiley Periodicals, Inc.
Three‐dimensional imaging flow cytometry through light‐sheet fluorescence microscopy

Published: January 2017

AbstractFlow cytometry is the tool of choice for high‐speed acquisition and analysis of large cell populations, with the tradeoff of lacking intracellular spatial information. Although in the last decades flow cytometry systems that can actually acquire two‐dimensional spatial information were developed, some of the limitations remained though, namely constrains related to sample size and lack of depth or dynamic information. The combination of fluidics and light‐sheet illumination has the potential to address these limitations. By having cells travelling with the flowing sheath one can, in a controlled fashion, force them at constant speed through the light‐sheet enabling the synchronized acquisition of several optical sections, that is, three‐dimensional imaging. This approach has already been used for imaging cellular spheroids, plankton, and zebra‐fish embryos. In this review, we discuss the known solutions and standing challenges of performing three‐dimensional high‐throughput imaging of multicellular biological models using fluidics, while retaining cell and organelle‐level resolution. © 2017 International Society for Advancement of Cytometry

Published: January 2017

New poly‐phenolic branched‐chain fatty acid (poly‐PBC‐FA) products were synthesized from a combination of soybean fatty acids and phenolic materials through a highly efficient zeolite catalyzed arylation method. These poly‐PBC‐FAs are liquid at room temperature and do not have the unpleasant odor like the parent phenol reagent. They were found to be comprised of various numbers of phenol rings on the fatty acid chain, and this is important because compounds with a higher number of hydroxyl groups are expected to have better antimicrobial activities. Detailed characterization using gas chromatography and high performance liquid chromatography coupled to a quadrupole‐time of flight mass spectrometer techniques were used to measure the number of phenol groups on the alkyl fatty acid chains. A cost process modeling technique was used to determine the economic feasibility of this arylation process to make these important poly‐PBC‐FA products.Practical applications: The continued outbreaks of Listeria monocytogenes in foods imply that current antimicrobial products are not sufficient to control pathogen contamination. These new phenolic branched‐chain fatty acid products contain hydrophobic and hydrophilic properties. They are found to bear close resemblance to antimicrobial compounds that are receiving a great deal of attention for biomedical and/or materials applications. This finding is highly encouraging because the phenolic products are odorless which should make them appealing for possible food applications to kill the harmful Listeria monocytogenes.New poly‐phenolic branched‐chain fatty acid products were synthesized from a combination of soybean fatty acids and phenol materials through a highly efficient zeolite catalyzed arylation method. These isolated phenolic fatty acid materials are liquid at room temperature and do not have the unpleasant odor like the parent phenol reagent. Mass spectroscopy results confirmed more than one phenol group is on the alkyl chain due to the polyunsaturated fatty acid materials used. The cost model indicated that the process is feasible at the industrial scale.

SummaryObjectiveThe aim of this study is to determine whether the use of 7 tesla (T) MRI in clinical practice leads to higher detection rates of focal cortical dysplasias in possible candidates for epilepsy surgery.MethodsIn our center patients are referred for 7 T MRI if lesional focal epilepsy is suspected, but no abnormalities are detected at one or more previous, sufficient‐quality lower‐field MRI scans, acquired with a dedicated epilepsy protocol, or when concealed pathology is suspected in combination with MR‐visible mesiotemporal sclerosis—dual pathology. We assessed 40 epilepsy patients who underwent 7 T MRI for presurgical evaluation and whose scans (both 7 T and lower field) were discussed during multidisciplinary epilepsy surgery meetings that included a dedicated epilepsy neuroradiologist. We compared the conclusions of the multidisciplinary visual assessments of 7 T and lower‐field MRI scans.ResultsIn our series of 40 patients, multidisciplinary evaluation of 7 T MRI identified additional lesions not seen on lower‐field MRI in 9 patients (23%). These findings were guiding in surgical planning. So far, 6 patients underwent surgery, with histological confirmation of focal cortical dysplasia or mild malformation of cortical development.SignificanceSeven T MRI improves detection of subtle focal cortical dysplasia and mild malformations of cortical development in patients with intractable epilepsy and may therefore contribute to identification of surgical candidates and complete resection of the epileptogenic lesion, and thus to postoperative seizure freedom.

AbstractObjectiveTo compare perioperative details among patients who underwent gynecologic surgery between traditional laparoscopy and three‐dimensional laparoscopy.MethodsThe present prospective non‐randomized study enrolled all consecutive patients diagnosed with gynecologic pathology who underwent laparoscopic surgery at Reina Sofia Hospital, Cordoba, Spain between January 1 and April 30, 2014. Perioperative data, adverse events, and patient satisfaction were compared between patients who underwent treatment with two‐dimensional and three‐dimensional laparoscopic surgery techniques.ResultsThe study enrolled 60 consecutive patients; 31 (52%) patients who underwent three‐dimensional surgery and 29 (48%) who underwent traditional two‐dimensional surgery. No significant differences were observed in the adverse‐event rate, operating time, or perioperative parameters. A higher use of sealing devices was recorded among patients who underwent three‐dimensional laparoscopy (P=0.021). No difference was recorded in patient satisfaction between the two patient groups.ConclusionAlthough there was no impact on surgical outcomes, three‐dimensional surgery could give a more accurate view of the surgical field. Performing three‐dimensional surgery could be beneficial for more complex procedures although further comparative studies are required to investigate this hypothesis.
Clinical Problems of Ovulation Defects
Authors: Grant Alan 
Published: January 2017

ABSTRACTThe clinical manifestations of luteal phase defect. a condition frequently associated with pathological ovulation, have been reviewed along with methods of diagnosis and treatment. Data have been presented that indicate frequent associations of corpus luteum insufficiency with infertility and early abortion. The obvious similarities between experimental and clinical findings suggest strongly that this pathological entity is closely related to the ovulation defects that have been shown to cause a variety of reproductive anomalies in various laboratory animals.

The Risk of Dying from Legal Abortion in the United States, 1972–1975
Authors: Cates Willard , Grimes David A. , Smith Jack C. , Tyler Carl W. 
Published: January 2017

ABSTRACTData gathered by the Center for Disease Control (CDC) through epidemiologic surveillance of deaths associated with legal abortions performed from 1972 through 1975 are analyzed by the type of procedure and the gestational age of the patients. Analysis shows that deaths increase at higher gestational ages and that the risk of death from abortion is highest with hysterotomy and hysterectomy and lowest with suction curettage. Second trimester instillation procedures are associated with higher rates of mortality than first trimester curettage procedures, even when dilatation and evacuation at 13–15 weeks' gestation is included as a curettage procedure. A case history of a patient who died as a result of legal abortion demonstrates that while legal abortion is a safe surgical procedure, some of the deaths that still occur can be prevented.
The Cold Sterilization of Abortion Cannulae
Authors: Spence Michael R. , King Theodore M. , Brockman Mary 
Published: January 2017

ABSTRACTThe purpose of this study was to determine if cold sterilization is a feasible method for sterilizing abortion cannulae and, if so, to find the appropriate solutions and time intervals for this sterilization process. Study findings show that abortion cannulae can be cold sterilized by soaking them for a minimum of 10 minutes in a solution of Cidex® or 95% ethanol. Soaking the cannulae for 20 minutes in a 2% tincture of iodine solution also appears to be useful for decontamination purposes.

Published: January 2017

ABSTRACTProstaglandin E2 (PGE2) was administered orally to 109 patients to induce labor. Sixty‐five of these patients had an amniotomy prior to PGE2 administration. PGE2 was administered to the remaining. 44, who subsequently underwent amniotomy only after their cervices had reached approximately 6 cm dilation. Labor was successfully induced in 95 patients, but its duration was shorter when amniotomy was immediately followed by PGE2 administration. Failed cases were successfully managed with amniotomy and oxytocin infusion. Maternal side effects were minimal. No fetal complications occurred.

A Comparison of Socio‐demographic and Fertility Characteristics of Women Sterilized in Hospitals and Camps
Authors: Pachauri Saroj 
Published: January 2017

ABSTRACTSocio‐demographic characteristics of 5846 women undergoing sterilization in hospitals and 1752 women undergoing sterilization in camps in India are analyzed. The average age of women accepting sterilization was 29.8 years; the mean number of living children was 4.2. Women sterilized in hospitals were of significantly higher age and parity than those sterilized in camps. The mean parity for all women was 4.6. A steep increase in median parity was observed with increasing age in both hospitals and camps. The study indicates that, while the level of education may affect acceptance of sterilization, there is no minimum level of education necessary for its acceptance. Most of the women in the study were not gainfully employed. As expected, most of the women were Hindus. Muslims were underrepresented in the hospital series; in camps, however, Muslims showed a much higher rate of acceptance of sterilization. The rate of pregnancy wastage was significantly higher in the hospital and the child loss rate was significantly higher for the camp cases. While the rate of previous abortions was higher for low parity women, the child loss rate was higher for high parity women. The child loss parity ratio was significantly higher for the camps than for the hospital cases. The vast majority of women in both hospitals and camps reported no previous contraceptive practice. Sterilization appears to have been the method of choice for most of these women.

Published: January 2017

ABSTRACTOne hundred forty‐two cases of epithelial ovarian carcinoma were treated from 1972 to 1976 in the Department of Obstetrics and Gynaecology, University Central Hospital, Turku, Finland. Repeat laparotomy was performed on 37 of the patients about six months after total extirpative surgery (group I). In addition, a second laparotomy was performed on 14 patients after partial surgery or exploratory laparotomy (group II). All patients were given external radiation therapy combined with cytostatic treatment prior to the repeat laparotomies. A preclinical carcinoma was detected in six of the 37 patients in group I. Two of them are asymptomatic after five years of follow‐up. In group II, total surgery after initial partial or exploratory laparotomy succeeded in half of the cases. Serous and endometrioid carcinomas appeared to respond best to conservative therapy preceding repeat laparotomy.
Correlation of Ominous Fetal Heart Rate Pattern and Scalp Blood pH with One‐Minute Apgar Score
Authors: Ayromlooi Jahangir , Tobias Mitchell , Berg Peter 
Published: January 2017

ABSTRACTFetal monitoring data were analyzed in 176 labors that developed ominous fetal heart rate deceleration patterns (FHRDP) during the two hours prior to delivery in an effort to identify how neonatal condition could be most accurately predicted. It was found that ominous FHRDP corresponded to a one‐minute Apgar score of 6 or less in only 15.3% of cases. When patterns with fetal scalp blood pHs (FSBpH) of ≤7.20 (n = 18) were considered, 44.4% had an Apgar score of 6 or less. Mean Apgar scores for those neonates who had a pH of ≤7.20 were significantly less than the mean Apgar score of the control group (p < 0.001 for all deceleration types). The result reveals that FSBpH has a better predictive value than FHRDP alone for neonatal depression. It is suggested that, as soon as ominous FHRDP occurs during labor, FSBpH be performed to assess not only fetal status but also to predict neonatal outcome.
Heparin Therapy in Postcesarean Septic Pelvic Thrombophlebitis
Authors: Malkamy Hormoz 
Published: January 2017

ABSTRACTEleven cases of septic pelvic thrombophlebitis and persistant fever following cesarean section and cesarean hysterectomy are presented. Addition of heparin to the antibiotic regimen of these patients produced a clinical response within 1‐5 days, except in two patients who developed septic pulmonary emboli, which finally resolved with continued heparin therapy. An incidental finding was a high incidence of pelvic thrombophlebitis following hypogastric artery ligation. The results justify a trial of heparin therapy, before resorting to exploratory laparotomy, in postpelvic surgery patients who have unexplained fever.
