Laparoscopic uterosacral ligament suspension: a systematic review and meta-analysis of safety and durability

Introduction Pelvic organ prolapse (POP) is a widespread condition affecting from 40% to 60% of women. Reconstructive vaginal surgeries are the most commonly performed procedures to treat POP. Among those, uterosacral ligament suspension (USLS), which is usually performed transvaginally, preserves pelvic statics and dynamics and appears to be an effective method. Laparoscopic USLS is a valid alternative to vaginal approach, and the aim of our review is to confirm its safety and feasibility and to compare clinical outcomes among the procedures. Materials and methods Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed and Scopus databases in December 2022. We made no restriction on the publication year nor on the country. Data about POP-Q recurrence rate (RR), intraoperative and postoperative complications (graded according to Clavien–Dindo classification), readmission rate, and reoperation rate were collected and analyzed. We used comparative studies for meta-analysis. Results A total of nine studies fulfilled inclusion criteria: two articles were non-comparative retrospective observational studies, three more articles were comparative studies where laparoscopic USLS was confronted with other surgical techniques (only data of laparoscopic USLS were analyzed), and four were comparative retrospective cohort studies between laparoscopic and vaginal USLS procedures. The comparative studies were enrolled in meta-analysis. Patients were analyzed concerning perioperative risks and the risk of recurrence. The meta-analysis highlighted that there was no clear inferiority of one technique over the other. Discussion Laparoscopic USLS is a technique with a low complication rate and low recurrence rate. Indeed, laparoscopic procedure allows better identification of anatomical landmarks and access to retroperitoneum. Moreover, efficacy over time and durability of Laparoscopic (LPS) USLS was also observed. However, these data should be weighed in light of the length of follow-up, which was in a very short range. Further, focused and prospective studies will be necessary to confirm this finding.
Application of mechanistic model for phosphorus uptake by barley under low temperature conditions

Abstract Mechanistic single root model that estimates nutrient flow and total uptake of nutrients was applied to phosphorus (P) uptake by barley under different temperature (8 and 20°C) conditions with and without P application treatments. Temperature markedly affected growth. The difference between P treatments was rather negligible. The dry-matter weight and P uptake increased slightly with P application under low temperature conditions, unlike in the case of higher temperature conditions. Root length under low temperature conditions was short, with large radius. P application led to a reduction of the root length. Soil solution P concentration decreased under low temperature conditions. Estimated P uptake with the model was within the confidence limit of experimental values but rather smaller than the observed values for the plants which did not receive P (74 and 94%). Based on sensitivity analysis of the model, lower P concentration in the soil solution was considered to be the reason for the lower P uptake under lower temperature conditions. The effect of P application was estimated to be larger under low temperature conditions than under high temperature conditions (60 and 17% increase, respectively). Diffusion around root along with root length seemed to be the process that dominated P uptake under different temperature conditions.
Nanoparticle Shape and Optical Band Gap Alteration in PbSe Nanostructure Thin Films with Deposition Temperature Controlling

In this work, the authors investigate the deposition temperature that governs alteration of the nanoparticle shape in PbSe nanostructure thin films. The experimental data showed that the deposition temperature can alter the shape and optical band gap. The nanoparticle arrays were grown on glass substrate using a facile chemical bath deposition method. The films were characterized by X-ray diffraction, UV-Visible spectroscopy for band gap estimation, and scanning electron microscopy to investigate the particle size and morphology of the thin films. The optical band gap decreases from 2.3 to 1.2 eV with an increase in the deposition temperature.
Optimum CFST bioreactor design: Experimental study using batch growth parameters for saccharomyces cerevisiae producing ethanol

An optimum CFST bioreactor design equation is presented which can be used with linear growth-associated product inhibition models. Batch experiments were performed to determine Saccharomyces cerevisiae growth parameters required for solving the optimum design equation. The three bioreactors were designed in decreasing volumes to achieve theoretical glucose conversions of 99.9% and 99.99%. At steady state, the bioreactors appeared to reach the theoretical conditions as long as the flowrates were held equal or slightly below the optimum conditions. At very low flowrates, biomass death was observed in downstream reactors while at high flowrates, the theoretical conversions were not achieved. The experimental results confirm that optimally designed bioreactors can offer lower processing volumes to achieve high substrate conversions as compared to single CFST bioreactors.
Reply to “Comment on ‘Quasisaddles as relevant points of the potential energy surface in the dynamics of supercooled liquids’ ” [J. Chem. Phys. 118, 5263 (2002)]

We reply to the Comment on the paper “Quasisaddles as relevant points of the potential energy surface in the dynamics of supercooled liquids” [J. Chem. Phys. 116, 10297 (2002)]. While we agree with J. P. K. Doye and D. J. Wales on their improved enumeration of zero curvature directions at quasisaddle points, we criticize their statement that this has important implications for the interpretation of our results. Indeed, we show here that the temperature dependence of the order of quasisaddles and true saddles are numerically coincident, providing a strong support to our previous interpretation.

Effects of Carriers on Amination of Ethanol to Acetonitrile over Catalysts Loaded with Cu

In this study, we first purposefully synthesized SAPO-11 and Na-ZSM-23 molecular sieves. The catalysts loaded with Cu were prepared by using seven typical carriers, including Montmorillonite-K10, USY, SAPO-11, Na-ZSM-23, γ-Al2O3, ZnO and MgO, and the performance of the catalysts was tested for amination of ethanol. The results demonstrate that the acid-base property of the carriers is closely related with the results of amination of ethanol over the catalysts. Among all these catalysts, 15%Cu/Na-ZSM-23 shows the highest yield of acetonitrile.
Premature ovarian insuffi ciency in children: Etiology, clinical management and treatment

Premature ovarian insuf iciency (POI) used to be called primary ovarian insuf iciency or premature ovarian failure [1]. It refers to a clinical syndrome caused by a signi icant decline or loss of ovarian function before the age of 40 years [2,3]. The current diagnostic criteria believe that primary or secondary amenorrhea with no less than two abnormal serum sex hormones (low estrogen and high gonadotropin) that occurred before the age of 40 years can be diagnosed [2]. The prevalence of POI in the general population is roughly 25% – 5%, and some reports indicate that 0.01% of 20-year-old young women may have POI [4]. POI has a serious impact on women’s health in all aspects, such as irregular menstruations, anxiety disorders, memory de icits, hot lashes, and night sweats, etc.[5]. POI seriously affects women’s health in all aspects, especially adolescents and children. Losing normal ovarian function before puberty begins will affect her normal life and social intercourse as a woman. Early diagnosis, intervention, and treatment can effectively protect the residual ovarian function, which is of great signi icance to patients’ personal life, family harmony, and social stability. Therefore, it is of great signi icance to diagnose and start treatment in Abstract
Geomicrobiology of Sulfidic Mine Dumps: A Short Review

The geomicrobiology of sulfidic mine dumps is reviewed. More than 30 microbiological studies of sulfidic mine dumps have been published. Mainly culturing approaches such as most probable number (MPN) or agar plates were used to study the microbial communities. More recently, molecular biological techniques such as FISH, CARD-FISH, Q-PCR, T-RFLP, DGGE, or cloning have been applied to quantify microorganisms and to investigate the microbial diversity. Aerobic Fe(II)- and sulfur compound oxidizing microorganisms oxidize pyrite, pyrrhotite and other metal sulfides and play an important role in the formation of acid mine drainage (AMD). Anaerobic microorganisms such as Fe(III)-reducing microorganisms dissolve Fe(III)(hydr)oxides and may thereby release adsorbed or precipitated metals. Sulfate-reducing microorganisms precipitate and immobilize metals. In addition to the microbial communities several biogeochemical processes have been analyzed in mine dumps. Pyrite or pyrrhotite oxidation rates have been measured by different techniques: Column experiments, humidity cells, microcalorimetry, or oxygen consumption measurements. Analyses of stable isotopes of iron, oxygen and sulfur have yielded valuable information on biogeochemical reactions. The microbiology and the biogeochemical processes in sulfidic mine dumps have to be understood for control and prevention of AMD generation and to provide different possibilities for remediation concepts. Today, remediation measures, e.g. under water storage of the waste or covering of the dumps, focus on the inhibition of pyrite oxidation to keep the toxic compounds inside the mine waste dumps. As an alternative to the inhibition of pyrite oxidation, metals which also have economic value could be extracted from mine dumps by the application of different metal extraction technologies including bioleaching.
Paper 35: The Influence of Mass Velocity on Friction Pressure Gradients during Steam-Water Flow:

From analysis of data for the flow of steam-water mixtures in tubes at pressures between 3 MN/m2 [435 lb/in2 (abs.)] and 17·5 MN/m2 [2540 lb/in2 (abs.)] equations for friction pressure gradient are developed. These equations allow for the influence of the ‘mass velocity effect’, not previously allowed for in accepted correlations. The equations are in a form making them applicable at the critical point, and are compared with the data of Miropolskii, Isbin, and Berkowitz for steam-water flow.
Porting DotGNU to Embedded Linux

Programming PLC systems is limited by the provided libraries. In contrary, hardware-near programming needs bigger e orts in e. g. initializing the hardware. This work o ers a foundation to combine advantages of both development sides. Therefore, Portable.NET from the DotGNU project has been used, which is an implementation of CLI, better known as . NET . The target system is the PLCcore5484 microcontroller board, developed by SYS TEC electronic GmbH. Built upon the porting, two variants to use interrupt routines withing the Portabe.NET runtime environment have been analyzed. Finally, the reaction times to occuring interrupt events have been examined and compared. Die Programmierung für SPS-Systeme ist durch die gegebenen Bibliotheken beschränkt, während hardwarenahe Programmierung einen gröÿeren Aufwand durch z.B. Initialisierungen hat. Diese Arbeit bietet eine Grundlage, um die Vorteile beider Entwicklungsseiten zu kombinieren. Dafür wurde Portable.NET des DotGNUProjekts, eine Implementierung des CLI, bekannter unter dem Namen . NET , benutzt. Das Zielsystem ist das PLCcore-5484 Mikrocontrollerboard der SYS TEC electronic GmbH. Aufbauend auf der Portierung wurden zwei Varianten zur Einbindung von Interrupt-Routinen in die Portable.NET Laufzeitumgebung untersucht. Abschlieÿend wurden die Reaktionszeiten zu eintretenden Interrupts analysiert und verglichen.

Neural network based double-objective optimization and application to pulp washing process improvement

For a countercurrent paper pulp washing system, the requirements of craft to residual soda in the final washed pulp and Baume degree in the first stage filtrate tank are usually inconsistent. To compromise this pair of contradiction, a neural network (NN) based two-objective optimization algorithm is proposed. Two NN models of the residual soda in washed pulp and the Baume degree in the first stage filtrate tank are obtained by a two-step identification method. An external penalty function method based on the double-objective optimization algorithm on the hot clean water input and final washed pulp output is employed. In terms of the DCS development platform of Xinhua XDPS 4000, China, a novel pulp washing process DCS is implemented and put into operation in paper mills in China with notable profit.
Tropical Deep Convection and Ozone Formation

Abstract Theoretical studies, aircraft, and space-borne measurements show that deep convection can be an effective conduit for introducing reactive surface pollutants into the free troposphere. The chemical consequences of convective systems are complex. For example, sensitivity studies show potential for both enhancement and diminution of ozone formation. Field observations of cloud and mesoscale phenomena have been investigated with the Goddard Cumulus Ensemble and Tropospheric Chemistry models. Case studies from the tropical ABLE 2, STEP, and TRACE-A experiments show that free tropospheric ozone formation should increase when deep convection and urban or biomass burning pollution coincide, and decrease slightly in regions relatively free of ozone precursors (often marine). Confirmation of post-convective ozone enhancement in the free troposphere over Brazil, the Atlantic, and southern Africa was a major accomplishment of the September–October 1992 TRACE-A (Transport and Atmospheric Chemistry near the E.
Fractal Dimension of Cellulose Powders Analyzed by Multilayer BET Adsorption of Water and Nitrogen

The aim of this study was to show that multilayer fractal Brunauer−Emmett−Teller (mfBET) theory can be used as a tool to obtain information about the distribution of water in cellulose powder particles of varying crystallinity. Microcrystalline cellulose, agglomerated micronized cellulose, low-crystallinity cellulose, and cellulose powders from green and brown algae were characterized by scanning electron microscopy and mfBET analysis on water and nitrogen adsorption isotherms. The distribution of water in the cellulose materials was found to be characterized by a fractal dimension smaller than 1.5 for all powders. The results showed that for highly crystalline cellulose materials, such as Cladophora cellulose, the cellulose−water interactions take place mainly on cellulose fibril surfaces adjacent to open pores without causing any significant swelling of the material. For less ordered celluloses the water interaction was found to take place inside the bulk material and the water uptake process caused the.
Exergetic performance evaluation of heat pump systems having various heat sources

In this study heat pump systems having different heat sources were investigated experimentally. Solar‐assisted heat pump (SAHP), ground source heat pump (GSHP) and air source heat pump (ASHP) systems for domestic heating were tested. Additionally, their combination systems, such as solar‐assisted‐ground source heat pump (SAGSHP), solar‐assisted‐air source heat pump (SAASHP) and ground–air source heat pump (GSASHP) were tested. All the heat pump systems were designed and constructed in a test room with 60 m2 floor area in Firat University, Elazig (38.41°N, 39.14°E), Turkey.
Combustion, pyrolysis, gasification, and liquefaction of biomass

All the products now obtained from oil can be provided by thermal conversion of the solid fuels biomass and coal. As a feedstock, biomass has many advantages over coal and has the potential to supply up to 20% of US energy by the year 2000 and significant amounts of energy for other countries. However, it is imperative that in producing biomass for energy we practice careful land use. Combustion is the simplest method of producing heat from biomass, using either the traditional fixed-bed combustion on a grate or the fluidized-bed and suspended combustion techniques now being developed. Pyrolysis of biomass is a particularly attractive process if all three products - gas, wood tars, and charcoal - can be used. Gasification of biomass with air is perhaps the most flexible and best-developed process for conversion of biomass to fuel today, yielding a low energy gas that can be burned in existing gas/oil boilers or in engines. Oxygen gasification yields a gas with higher energy content that can be used in pipelines or to fire turbines. In addition, this gas can be used for producing methanol, ammonia, or gasoline by indirect liquefaction. Fast pyrolysis of biomass produces a gas rich in ethylenemore » that can be used to make alcohols or gasoline. Finally, treatment of biomass with high pressure hydrogen can yield liquid fuels through direct liquefaction. « less
Towards Biocatalytic Synthesis of β-Lactam Antibiotics

This review describes the remarkable transition in the manufacture of β-lactam antibiotics, which is driven by the desire to reduce or eliminate the production of waste and the dependence on organic solvents. To this effect, traditional chemical procedures are gradually being replaced by biotransformations. The β-lactam antibiotics industry has led the way in the introduction of biocatalysis in the fine chemicals industry by replacing the chemical multi-step process for the penicillin nucleus 6-aminopenicillanic acid (6-APA) by an enzymatic one in the early 1990's. Recently, bioprocesses have been developed for the synthesis of the cephalosporin nucleus, 7-aminodeacetoxycephalosporanic acid (7-ADCA) from a penicillin precursor and will shortly be commercialized. Thirty years of research have now resulted in viable enzymatic procedures for coupling the β-lactam nuclei with D-phenylglycine side-chains. The necessary adaptations in the synthesis of the side-chain donors have likewise resulted in more efficient procedures. 1 Introduction 2 Semi-Synthetic β-Lactam Antibiotics: Industrial Production Prior to 1985 3 Biocatalytic Synthesis of β-Lactam Nuclei 3.1 6-Aminopenicillanic Acid 3.2 7-Aminodeacetoxycephalosporanic Acid 4 Biocatalytic Routes to Side-Chains 4.1 Synthesis of the Side-Chain Building Blocks 4.2 Synthesis of Activated Side-Chain Donors 5 Enzymatic Coupling of the Side-Chains to the β-Lactam Nuclei 5.1 Chemical Procedures 5.2 Enzymatic Coupling 5.3 Practical Procedures for Enzymatic Coupling6 Conclusion and Future Outlook
Study of Water Uptake in Whole Grain Barley by Two-Dimensional Correlation Near-Infrared Spectroscopy

ABSTRACT This study reports the use of near-infrared (NIR) reflectance spectroscopy combined with two-dimensional correlation (2D-COS) spectroscopy to monitor the effect of soaking and water uptake by the barley endosperm (Hordeum vulgare, L). The synchronous 2D-COS maps derived from the NIR spectra of barley endosperm showed similarities that could be explained by the regions in the spectra associated with water as well as with the biochemical and biophysical changes as a consequence of the water uptake by the grain. The results also demonstrated the potential of 2D-COS combined with NIR spectroscopy as an analytical tool to study changes in the biophysical characteristics of whole barley during steeping or soaking. This method can be used to obtain information about the effect of water uptake in other chemical characteristics of the endosperm of cereal grains.
Fusion and discharge of rat submandibular gland acinar secretory granules captured by quick freezing

This study was carried out to observe morphologically and quantitatively the membrane fusion of secretory granules and exocytotic figures during secretion while keeping alive the submandibular gland acinar secretory granules of male rats. The results showed that in comparison with the secretory granules of stimulated and control rats by quick freezing with OsO4. acetone and paraformaldehyde-acetone, (a) secretory granules apposed and fused with each other in a convex and concave form, and filamentous structure (90-100 A) and actin-like filaments (40 A) were intercalated between the two closely apposed granules, (b) part of the two fused outer leaflets of the granule disappeared in the initial stages of the two fused granule membrane and a fused, double thickness lipid bilayer was observed. After the contents of one granule were poured into the other fused granule, association of the two fused membranes was observed; and (c) appearance of a convex shaped granule membrane facing toward the plasma membrane and depression of the plasma membrane facing the cytoplasm represented the initial stage of exocytosis. On the other hand, filamentous structures intercalated between the plasma membrane and the granule membrane were detected. Lastly, (d) the width of the tubular structures in the control groups was narrower than that in the stimulated gland at discharge after the fusion of the two membranes. From these results it was concluded that the concave and convex form in the granule membrane fusion and the association of plasmalemma-granules with tubular structures in the exocytosis may be intrinsic phenomena of the double lipid bilayer in secretory granule fusion, thus confirming the exclusion of intramembranous particles.
A New Property of MCM-41: Drug Delivery System

A new application of MCM-41 mesoporous materials has been developed. Two kinds of surfactants, C16TAB and C12TAB, have been employed to get different pore sizes. The samples were disk-shaped conformed before and after charging with ibuprofen, an anti-inflammatory drug. In all the cases the weight percent ratio of drug/MCM-41 was 30%. The drug release plots show a different behavior depending on the method for charging the drug in the material but not on the employed surfactant.
