Authors: OBIMBO MM , KOIGI PK , NICOLE G.A , SANG D 
Published: May 2024

Introduction: Maternal pelvic dimensions are key to determining progress and outcome of labour. In addition, the size of the pelvis is a crucial reference point in attempting to predict cephalopelvic disproportion. There is paucity of data regarding pelvic dimensions amongst black Kenyan population despite the central significance of such data in local obstetrics practice.
Methods: A cross-sectional study of 50 female pelvic osteology specimens was performed at the National Museums of Kenya, Nairobi. Data were collected using a structured study instrument and were analyzed using Statistical Pack age for Social Sciences version 21.
Results: At the pelvic inlet, the true conjugate was 10.37 ± 1.02cm, the diagonal conjugate was 11.72 ± 1.07cm and the obstetric conjugate was 11.44 ± 0.78cm. The transverse diameter was 11.42 ± 0.96cm. In the mid-cavity, the anteroposterior diameter was 10.64 ± 1.00cm, while the interspinous diameter was 8.49 ± 0.92cm. At the outlet, the anteroposterior diameter was 9.66 ± 1.16cm, while the intertuberous diameter was 9.04 ± 0.92cm. The subpubic angle was 74.54 ± 9.72 degrees. The posterior depth was 9.95 ± 1.11cm, while the anterior depth was 3.24 ± 1.41 cm.
Conclusion: The average pelvic dimensions in this population are smaller than what has been observed in other populations. Of significance is that some morphometric dimensions were ominously smaller than what has been implicated in cephalopelvic disproportion. Imaging and clinical studies would help shed more light on correlation of the dimensions and obstetric outcomes in black Kenyan population.

В статье рассмотрена возможность получения композиционного цемента для гидротехнического строительства с применением тонкодисперсных алюмосиликатных пород — перлитов, коллоидной добавки в виде золя кремниевой кислоты и суперпластификатора — для повышения трещиностойкости гидротехнического бетона. Рассмотрена кинетика твердения цементного камня с добавкой стекловидного и закристаллизованного перлита различной степени дисперсности, коллоидной добавкой и суперпластификатором. Исследована структура цементного камня, модифицированного коллоидной добавкой и тонкодисперсным перлитом, в возрасте 3 и 28 сут. ﻿Показано, что с добавлением к портландцементу добавки тонкодисперсного перлита и суперпластификатора можно получить композиционный цемент с прочностными показателями не ниже, чем у исходного цемента, и с меньшим тепловыделением при гидратации по сравнению с традиционными состава-ми. Наиболее рациональны составы композиционного цемента, содержащие 10—20 % стекловидного перлита с удельной поверхностью 400—600 м2/кг, коллоидную добавку и суперпластификатор, обеспечивающие увеличение прочности цементного камня в возрасте 28 сут на 30—40 % по сравнению с контрольным составом. Для составов со стекловидным и закристаллизованным перлитом, золем кремниевой кислоты и суперпластификатором температура в 1-е и 2-е сутки гидратации ниже, чем у контрольных составов, на 12,7—14,1 и 11,0—13,3 % соответственно.
The article considers the possibility of obtaining composite cement for hydraulic engineering using finely dispersed aluminosilicate rocks - perlites, a colloidal additive in the form of silica sol and a superplasticizer to increase the crack resistance of hydraulic concrete. The kinetics of cement stone hardening using vitreous and crystallized perlite with varying degrees of dispersion, colloidal addi-tive and a superplasticizer are considered. Studies of the structure formation of cement stone modified with a colloidal additive and finely dispersed perlite at the ages of 3 and 28 days have been carried out. It is proved that with the addition of finely dispersed perlite and a superplasticizer to Portland cement, it is possible to obtain a composite cement with strength not lower than that of the initial cement and with less heat dissipation during hydration compared to traditional compositions. The most rational formulations of composite cement contain 10-20 % of vitreous perlite with a specific surface of 400-600 m2/kg, a colloidal additive and a superplasticizer, providing an increase in the strength of the cement matrix at the age of 28 days by 30-40 % compared to the control composition. For compositions with vitreous and crystallized perlite, silica sol and a superplasticizer, the temperature on the 1st and 2nd day of hydration is lower than that of control compositions by 12.7-14.1 and 11.0-13.3 %, respectively.

Objective: Computed tomography (CT) is superior to plain radiography for evaluating ankle syndesmosis, but anatomical variations can affect the measurements. This study aimed to assess the radiologic parameters of the incisura fibularis and the factors that could affect these parameters.
Materials and Methods: Lower-extremity CT angiography images were used to evaluate the morphology of the incisura fibularis, anterior and posterior tibiofibular distance, longitudinal and transverse length of the distal fibula, length and depth of the incisura fibularis notch, tibiofibular clear space, tibiofibular overlap, and fibular rotation. Each measured parameter was compared based on sex and body side. Also, the effect of age, height, weight, and body mass index (BMI) on parameters was evaluated.
Results: A total of 123 patients (83 men and 40 women) were included, and 246 ankles were measured. The CT measurements demonstrated excellent intraobserver and interobserver reliability. No statistically significant sex or side differences were found in tibiofibular overlap (TFO) and tibiofibular clear space, the most-used parameters in radiographs. Age, weight, and BMI were found to be correlated with TFO.
Conclusions: The present study provides CT measurements of the normal tibiofibular syndesmosis in the Turkish population. Also, the correlations of the parameters with age, height, weight, and BMI are presented. Therefore, TFO and tibiofibular clear space of the uninjured side can be used to plan the treatment of ankle injuries.
PTX3 mediates PI3K/AKT/mTOR signaling to downregulate apoptosis and autophagy to attenuate myocardial injury in sepsis
Authors: Cui Na , Chen Zhi , Yu Zhanbiao , Lv Xiaowei , Hu Zhenjie 
Published: May 2024

Background
This study aimed to investigate the effect and mechanism of Pentraxin 3 (PTX3) on myocardial injury in sepsis.

Methods
Thirty male C57BL/6 mice were randomly assigned to Groups A, B, or C. Mice in Groups A and B were injected with unloaded lentivirus, while mice in Group C were injected with lentivirus encoding PTX3 overexpression. Seven days after injection, septic myocardial injury mouse models were constructed following intraperitoneal injection with LPS in Groups B and C, and mice in Group A were intraperitoneally injected with normal saline. Cardiac function was examined using echocardiography; pathological variation of myocardial cells was measured through HE staining, transmission electron microscopy, and TUNEL staining; and Western blot was used to measure the expression of PI3K/AKT/mTOR pathway-related, autophagy-related, and apoptosis-related proteins in mice myocardial cells.

Results
PTX3 significantly improved cardiac function and structure in sepsis-stricken mice, and PTX3 alleviated cardiac damage caused by sepsis. PTX3 reduced the relative protein expression of p-PI3K, p-AKT, mTOR, LC3I/II, Beclin, ATG5, Bax, Caspase-3, and Caspase-9 in septic mouse cardiomyocytes and increased the relative protein expression of Bcl-2.

Conclusion
PTX3 can attenuate myocardial injury in sepsis due to the down-regulation of apoptosis and autophagy induced by the PI3K/AKT/mTOR pathway.
Threshold incentives over multiple periods and the sales hockey stick phenomenon
Authors: Sohoni Milind G. , Bassamboo Achal , Chopra Sunil , Mohan Usha , Sendil Nuri 
Published: November 2010

AbstractIn this article, we study threshold‐based sales‐force incentives and their impact on a dealer's optimal effort. A phenomenon, observed in practice, is that the dealer exerts a large effort toward the end of the incentive period to boost sales and reach the threshold to make additional profits. In the literature, the resulting last‐period sales spike is sometimes called the hockey stick phenomenon (HSP). In this article, we show that the manufacturer's choice of the incentive parameters and the underlying demand uncertainty affect the dealer's optimal effort choice. This results in the sales HSP over multiple time periods even when there is a cost associated with waiting. We then show that, by linking the threshold to a correlated market signal, the HSP can be regulated. We also characterize the variance of the total sales across all the periods and demonstrate conditions under the sales variance can be reduced. © 2010 Wiley Periodicals, Inc.

Published: November 2010

AbstractSiO2‐like layers deposited by means of the developed atmospheric pressure glow‐like DBD assisted CVD technology exhibit remarkable film properties, reported for the first time. The films synthesized in a roll‐to‐roll mode on polymeric webs, are as smooth as the substrate, irrespectively of the precursors (TEOS or HMDSO) and reactive gases (N2 or air) employed. Detailed AFM investigation on film morphology, surface roughness and auto correlation length (ξ) show that they are negligibly influenced with thickness and are similar to that of the polymeric substrate, indicating the self‐similar growth of the SiO2‐like layers in AP‐PECVD. The films are uniform with no defects or particle being incorporated during the deposition process. The produced single layers on polymeric substrate show excellent gas barrier performances towards O2 and H2O permeation (OTR: <5 × 10−3 cm3·m−2·day−1 and WVTR: <5 × 10−3 g·m−2·day−1).

Genetic Testing Likelihood: The Impact of Abortion Views and Quality of Life Information on Women's Decisions
Authors: Wilson Jessica L. , Ferguson Gail M. , Thorn Judith M. 
Published: November 2010

AbstractLittle is known about factors predicting the likelihood of choosing genetic testing in college aged women versus older women, including knowledge of quality of life (QOL) associated with a disorder. Using vignettes with female college students (Experiment 1: n = 257, mean age = 19.70 yrs) and female faculty/staff/alumni (Experiment 2: nnulliparous = 83, mean age = 30.20 yrs; nmothers = 53, mean age = 33.77 yrs), we examined the contribution of multiple factors to predicting genetic testing likelihood for cystic fibrosis. We investigated malleable situational factors (style of genetic risk presentation and providing QOL information including physical and social aspects) and stable dispositional factors (abortion views). Parity (i.e., prior births) was more influential in women's genetic testing likelihood than was age. Greater acceptability of abortion for oneself and self‐assessed knowledge following QOL information were predictors of higher testing likelihood for college students. Greater acceptability of abortion for another person was a predictor for nulliparous women. Abortion views moderated the effect of predictors for nulliparous women and mothers. Findings encourage genetic counselors to utilize QOL information to promote informed decision making through genetic testing.

Published: November 2010

AbstractObjective:To evaluate the correlation between caloric and vestibular evoked myogenic potential test results, initial audiogram data, and early hearing recovery, in patients with idiopathic sudden hearing loss.Materials and methods:One hundred and four patients with unilateral idiopathic sudden hearing loss underwent complete neurotological evaluation. Results for vestibular evoked myogenic potential and caloric testing were compared with patients' initial and final audiograms.Results:Overall, abnormal vestibular evoked myogenic potential responses occurred in 28.8 per cent of patients, whereas abnormal caloric test results occurred in 50 per cent. A statistically significant relationship was found between the type of inner ear lesion and the incidence of profound hearing loss. Moreover, a negative correlation was found between the extent of the inner ear lesion and the likelihood of early recovery.Conclusion:In patients with idiopathic sudden hearing loss, the extent of the inner ear lesion tends to correlate with the severity of cochlear damage. Vestibular assessment may be valuable in predicting the final outcome.

Published: November 2010

AbstractObjective:This study aimed to use a new otological technique, malleus relocation, to solve the problems of ossicular reconstruction undertaken during revision stapes surgery for incus necrosis.Study design:Prospective study of 12 patients undergoing revision stapedectomy for incus necrosis, in the otolaryngology department of Mansoura University, Egypt.Patients and methods:Twelve patients underwent ossiculoplasty between June 2004 and June 2007, as part of revision surgery for otosclerosis with incus necrosis. All patients underwent ossiculoplasty using the malleus relocation technique. Ossiculoplasty used the patient's own, necrosed incus between the relocated malleus and the footplate.Results:Post-operative air–bone gap closure to within 10 dB was achieved in seven patients (58.3 per cent). An air–bone gap of less than 20 dB was obtained in 10 patients (83.3 per cent). Deterioration of bone conduction by 10 dB occurred in one case. No patients were left with a ‘dead ear’. Patients’ hearing was stable throughout the follow-up period (range six to 40 months; mean ± standard deviation 23.5 ± 12.8 months).Conclusion:These findings indicate that malleus relocation, performed during revision stapes surgery, is a safe and efficient technique for the treatment of incus necrosis.

Authors: Demarco R C , Rossato M , de Oliveira J A A , Hyppolito M A 
Published: November 2010

AbstractBackground:Transtympanic administration of gentamicin may be suitable to achieve unilateral vestibular ablation, in order to control unilateral Ménière's disease. In low doses, gentamicin appears to affect selectively the vestibular system, with relative sparing of the cochlea. An experimental study on guinea pigs was conducted to determine what single dose of gentamicin would produce a unilateral vestibular organ lesion when applied to the middle ear.Study design:Experimental and prospective.Methods:Four groups of guinea pigs received different gentamicin doses (1, 5, 10 and 25 mg) administered to the middle ear. The animals' vestibular organs were then assessed by scanning electron microscopy, in order to quantify the level of vestibular damage.Results:Study of the utricular macula and the ampullar crista of the lateral semicircular canal revealed vestibular neuroepithelial lesions in all infused ears.Conclusions:The severity of the vestibular neuroepithelial lesions was dose-dependent. Lower gentamicin doses were observed to damage vestibular structures more than cochlear structures.

Published: November 2010

AbstractSpace-charge waves in a relativistic electron beam that completely fills a cylindrical metallic waveguide and is guided by an ion channel are analyzed numerically. Equilibrium consists of a uniform and rigid rotation without betatron oscillations. Using cold fluid equations a differential equation and boundary conditions are derived that constitute an eigenvalue problem. This eigenvalue problem is solved, numerically, with the finite difference scheme using shooting method. Dispersion characteristics and electrostatic potential structures of azimuthally symmetric and nonsymmetric space-charge waves are studied. Perfect agreement with analytical results at asymptotic limit of zero axial velocity is found. It was found that relativistic effects modify the dispersion characteristics of the space-charge waves considerably and can concentrate the electric field energy of the wave into a thin and small shell around the axis.
THE AGE OF PROTHERO: BRITISH HISTORIOGRAPHY IN THE LONG FIN DE SIÈCLE, 1870–1920
Authors: Bentley Michael 
Published: November 2010

ABSTRACTThis paper revisits two generations of highly talented and significant historians who flourished in Britain between c. 1870 and 1920. George Prothero stood high among them and he, with his brother Roland, receives a good deal of attention at the centre of the argument here. But others stood still higher: Tout, Firth, Poole, Acton, the incomparable Maitland; and the purpose of the piece is to present a portrait of the British historical profession as a whole during a crucial period of its formation by using the Protheros’ experience as a platform from which to depart. The journey inevitably begins with that Prothero experience seen as a microcosm of greater tendencies; but it soon winds away toward Germany and Scotland and France; we pause to admire fresh perspectives yielded in what had become an age of edition and what would become an age of economic and social history. Of course the track leads also to Sarajevo and the implications of European war for a fledgling profession. All this itinerary lends an opportunity, therefore, to think through some of the themes and characteristics which made this period of development distinctive; but it also warns and guards against reducing these years to a time of ‘transition’, remarkable only for what would follow it. The personalities and achievements discussed here deserve better of us and recommend that we devote more energy to considering the features of the age of Prothero, for their own sake and in their own terms.
