Objective. This work studied the influencing factors of age, level of education, family planning awareness, relationship with partner, the age at which sexual relationships were initiated, parity, the method of contraceptive previously used, the type of contraceptive pill used and the duration of oral hormonal contraception (OC) use in relation to the modification of sexual desire in OC users. Materials and Methods. Prospective study of 760 OC users at the Family Planning Center “Marina Alta” in Alicante (Spain). A logistical regression analysis was carried out to study the relative risk of reduction in libido, taking other risk factors into account. Results. In the simple analysis, women who initiated sexual relationships between 18 and 25 years of age had a lower sexual desire in comparison with women who were sexually active before the age of 18 (OR = 2.11;CI: 1.15 - 3.91). Nulliparous women had a reduced sexual desire compared with those women that had given birth (OR = 2.32;CI: 1.41 - 3.82). An OC use of between 6 months and 1 year reduced sexual desire in comparison with a use of less than 6 months (OR = 0.24;CI: 0.09 - 0.64). In the multivariate analysis, age (OR = 1.12;CI: 1.01 - 1.21) and the use of OC within an initial 6 month to a year period (OR = 0.24;CI: 0.09 - 0.64) presented a statistically significant relationship with the modification of sexual desire. The level of education, family planning awareness, relationship with partner, the method of contraception previously used and the type of contraceptive pill prescribed showed no statistical significance with the modification of sexual desire in OC users. Conclusions. Sexual desire in OC users decreases as a woman’s age increases and in an early stage of use in the first six months after beginning OC treatment.

Neural Regeneration Research 2025年第6期20卷 1709-1710页

作者： martin-Paul Agbaga Mohiuddin Ahmad Department of Cell Biology and Ophthalmology University of Oklahoma Health Sciences Centerand Dean McGee Eye InstituteOklahoma CityOKUSA

Very long chain-saturated and-polyunsaturated fatty acids(VLC-SFA and VLC-PUFA, respectively) are a functionally important class of fatty acids containing 28 carbons or more in their acyl chain. They are synthesized by the elongation of very long fatty acids-4(ELOVL4) enzyme, expressed mainly in the brain, retina, skin, testes, and meibomian gland, where these fatty acids are found(Agbaga et al., 2008). Further, these organs exhibit tissuespecific VLC-PUFA and VLC-SFA biosynthesis and incorporation into complex lipids for specific functions. In the brain, skin, and Meibomian glands, the ELOVL4 mainly makes VLC-SFA, which are incorporated into complex sphingolipids. In the retina, the ELOVL4 makes VLC-PUFA that are incorporated into phosphatidylcholine, that are critical for visual function, while in testes and sperm, the VLC-PUFA are incorporated into sphingolipids that are critical for fertility(Yeboah et al., 2021).

Artificial versus Natural Reuse of CO2 for DME Production：Are We Any Closer？

引用

Engineering 2017年第2期3卷 166-170页

作者： mariano martin Department of Chemical Engineering University of Salamanca Salamanca 37008 Spain

This work uses a mathematical optimization approach to analyze and compare facilities that either capturecarbon dioxide （CO2） artificially or use naturally captured COs in the form of lignocellulosic biomass towardthe production of the same product, dimethyl ether （DME）. In nature, plants capture COs via photosynthesisin order to grow. The design of the first process discussed here is based on a superstructure optimizationapproach in order to select technologies that transform lignocellulosic biomass into DME. Biomass is gas-ified; next, the raw syngas must be purified using reforming, scrubbing, and carbon capture technologiesbefore it can be used to directly produce DME. Alternatively, CO2 can be captured and used to produce DMEvia hydrogenation. Hydrogen （H2） is produced by splitting water using solar energy. Facilities based on bothphotovoltaic （PV） solar or concentrated solar power （CSP） technologies have been designed; their monthlyoperation, which is based on solar availability, is determined using a multi-period approach. The currentlevel of technological development gives biomass an advantage as a carbon capture technology, since bothwater consumption and economic parameters are in its favor. However, due to the area required for growingbiomass and the total amount of water consumed （if plant growing is also accounted for）, the decision to use biomass is not a straightforward one.

Coagulation Factor XII Congenital Deficiency in Women with Recurrent Miscarriage

引用

International Journal of Clinical Medicine 2011年第4期2卷 469-472页

作者： martin-loeches mariano Pallas Yadira Abad Ana Lloret Manuel Lopez-Galvez Jose Jesús 不详

Factor XII (Hageman factor) is an important protease that plays a major role in the initiation of the intrinsic pathway of blood coagulation and fibrinolysis and kinin formation. It is still unclear whether factor XII deficiency causes any disorders during pregnancy. Because the main clinical feature in patients with factor XII deficiency is thrombosis rather than bleeding, low dose aspirin would be expected to prevent first trimester miscarriage and a decrease in factor XII level itself was found to be an independent risk factor in recurrent miscarriage. The woman in a 31-year-old patient, with personal and family antecedents without interest and preceding obstetrics of two spontaneous abortions in the first quarter of the pregnancy without apparent cause. In the study of infertility practiced emphasizes a partition of not more than one centimetre of length in the uterine found by hysteroscopy exploration and in the study of hipercoagulability a light deficiency of the factor XII. Himself guideline processing with low dose of aspirin (125 mgr/day) and preconception folic acid (5 mgr/day), remains expectant mother and in the week 12 of her third pregnancy itself guideline antitrombotic prophylaxis with heparin of low molecular weight by subcutaneous way. The pregnancy reaches the week 39 without incidents of interest and the expectant mother give birth of spontaneous form to health boy. Repeated abortions may be associated with reduced level of factor XII activity of unknown origin and low-dose aspirin may prevent miscarriage caused for decreased factor XII levels in patients with a history of recurrent first trimester miscarriage.

Energy and Water Optimization in Biofuel Plants

引用

Chinese Journal of Chemical Engineering 2010年第6期18卷 914-922页

作者： Ignacio E. Grossmann mariano martin Center for Advanced Process Decision-making Department of Chemical Engineering Carnegie Mellon UniversityPittsburgh PA 15213 USA

In this paper we address the topic of energy and water optimization in the production of bioethanol from corn and switchgrass. We show that in order for these manufacturing processes to be attractive,there is a need to go beyond traditional heat integration and water recycling techniques. Thus,we propose a strategy based on mathe-matical programming techniques to model and optimize the structure of the processes,and perform heat integration including the use of multi-effect distillation columns and integrated water networks to show that the energy effi-ciency and water consumption in bioethanol plants can be significantly improved. Specifically,under some circum-stances energy can even be produced and the water consumption can be reduced below the values required for the production of gasoline.
