Progestins for pituitary suppression during ovarian stimulation in artificial reproductive technology
Authors: Gichuhi Wanyoike 
Published: February 2024

Background: Progestins can suppress endogenous luteinizing hormone secretion from the pituitary gland. Progestins can be used orally and are less expensive than gonadotrophin-releasing hormone (GnRH) analogs. However, early endometrial exposure to progestin precludes fresh embryo transfer (ET), but the emergence of vitrification for oocyte cryopreservation cycles allows more opportunities for using progestins for pituitary suppression.
Objective: To assess the mechanism of pituitary suppression by progestins, the effectiveness of progestins compared with GnRH analogs, the effect of progestins on oocyte and embryo developmental potential and euploidy status, and the cost-effectiveness of progestin-primed stimulation.
Methods: A literature search using the keywords “multiple waves of antral ovarian follicular development, In Vitro Fertilization, Ovarian stimulation ” was performed in the PubMed database.
Results: The duration of stimulation, gonadotrophin consumption, and oocyte yield were similar in progestins and GnRH analogs. However, progestins were associated with significantly lower gonadotrophin consumption than their analogs. Overall, live birth and clinical pregnancy rates per ET were similar to those of progestins and GnRH analogs. Studies comparing medroxyprogesterone acetate, dydrogesterone, and micronized progesterone suggest similar ovarian responses and pregnancy outcomes. The euploidy status of embryos and obstetric and neonatal outcomes from progestin-primed cycles are similar to those of embryos from conventional stimulation cycles. Despite the lower cost of progestins than GnRH analogs, the mandatory cryopreservation of all embryos followed by a deferred transfer may increase the cost per live birth with progestins compared with an artificial reproductive technology cycle culminating in a fresh ET.
Conclusion: Progestins present an effective option for women who do not contemplate a fresh ET, e.g., fertility preservation, anticipated hyper responders, preimplantation genetic testing, oocyte donors, and double stimulation cycles.

Teknologi yang semakin canggih membuat semua orang dapat mengakses apapun termasuk pengajaran-pengajaran baik yang sesuai firman Tuhan atau tidak. Hal ini dapat membuat orang-orang Kristen yang belum memiliki pemahaman yang benar tentang Anak Allah dapat terseret dan meninggalkan Yesus. Penelitian ini bertujuan memaparkan konsep Anak Allah berdasarkan Injil Yohanes dan memberikan gambaran kepada pendidik bagaimana mengajarkan konsep Anak Allah ini dalam Pendidikan Agama Kristen. Penelitian ini menggunakan penelitian kualitatif, pendekatan studi kepustakaan dengan metode analisis isi.
Hasil penelitian ini menunjukkan bahwa Yohanes menunjukkan bahwa gelar Anak Allah itu berkaitan dengan kemesiasan Yesus, asal-usul-Nya, mujizat-mujizat yang dilakukan-Nya, hubungannya dengan Bapa, keunikan-Nya sebagai Anak Allah, delapan sifat-sifat keunikan Yesus sebagai Anak Allah. Mengajarkan konsep Anak Allah perlu dilakukan dengan pendekatan budaya dan memperhatikan isu-isu yang sedang berkembang khususnya pengajaran-pengajaran yang sedang mencoba mengaburkan iman kristen. Mengajarkan konsep Anak Allah dimulai sejak dini dengan memperkenalkan Yesus melalui mujizat-mujizat, dan terus berkembang kepada kesatuan Anak dengan Bapa.

Catcalls: exotic cats discriminate the voices of familiar caregivers
Authors: Crews Taylor , Vonk Jennifer , McGuire Molly 
Published: February 2024

Background
The ability to differentiate familiar from unfamiliar humans has been considered a product of domestication or early experience. Few studies have focused on voice recognition in Felidae despite the fact that this family presents the rare opportunity to compare domesticated species to their wild counterparts and to examine the role of human rearing.

Methods
We tested whether non-domesticated Felidae species recognized familiar human voices by exposing them to audio playbacks of familiar and unfamiliar humans. In a pilot study, we presented seven cats of five species with playbacks of voices that varied in familiarity and use of the cats’ names. In the main study, we presented 24 cats of 10 species with unfamiliar and then familiar voice playbacks using a habituation-dishabituation paradigm. We anticipated that human rearing and use of the cats’ names would result in greater attention to the voices, as measured by the latency, intensity, and duration of responses regardless of subject sex and subfamily.

Results
Cats responded more quickly and with greater intensity (e.g., full versus partial head turn, both ears moved versus one ear twitching) to the most familiar voice in both studies. They also responded for longer durations to the familiar voice compared to the unfamiliar voices in the main study. Use of the cats’ name and rearing history did not significantly impact responding. These findings suggest that close human contact rather than domestication is associated with the ability to discriminate between human voices and that less social species may have socio-cognitive abilities akin to those of more gregarious species. With cats of all species being commonly housed in human care, it is important to know that they differentiate familiar from unfamiliar human voices.

Plants and human health are both negatively impacted by the soil's heavy metal toxicity. By using excess amounts of fertilizers, sewage sludge, and pesticides, smelting, burning coal, and other methods, they are introduced into the soil. Among different heavy metals copper and arsenic are very important but their higher concentrations cause several morphological and biochemical in plants. They become part of the food chain when fruits and vegetables are grown in contaminated soil and can cause serious health issues to consumers. On the other hand, ornamental plants are used for aesthetic beautification and could be explored for the phytoremediation of soil heavy metals. A recent study was conducted to observe the phytoremediation potential of Gladiolus (Gladiolus grandifloras) and chrysanthemum against different levels of copper (80 and100µg/kg of soil) and arsenic (80 and 100 µg/kg) in the soil under completely randomized design. Data of accumulated quantity of heavy metals were noted after the flowering stage of both plants by dividing into four parts including roots, stem, leaves, and flowers. Both Gladiolus and chrysanthemum accumulated significant amounts of Cu and As in roots, stem, leaves, and flower. Gladiolus and chrysanthemum accumulated 367, 456, 796 and 1278ppm Co and 356, 571, 832 and 1478ppm As respectively. Chrysanthemums took up significant amounts of Cu in the stem and easily translocated from stem flowers. The translocation ability of chrysanthemum was higher for both metals compared to Gladiolus. The data were analyzed by mini tab statistics 8.1.
On the optimization of cyclic adsorption separation processes
Authors: Cruz P. , Magalhães F. D. , Mendes A. 
Published: March 2005

AbstractAn innovative approach for the optimization of general cyclic adsorption separation processes (PSA and VSA), using the Skarstrom cycle with equalization, is proposed. The main objective is to study the optimal operating conditions for different adsorbent types, the optimal equalization stage configurations, and different underlying assumptions that are usually presumed in process modeling and simulation. The partial differential equations corresponding to the bulk gas‐phase mass balances were solved with a recent numerical technique, developed within our group, based on an adaptive multiresolution approach. The partial differential equations for the intraparticle balances were solved using the orthogonal collocation method. The proposed dynamic simulator proved to be very efficient in terms of computational time and memory requirements: stability and accuracy are simultaneously ensured. The optimization was performed with a successive quadratic‐programming algorithm that proved to be efficient because the optimum can be reached in a modest number of iterations. The proposed approach was applied to the particular case of oxygen production from air by PSA and VSA, with the aim of studying the performance of two commercially available adsorbents, commonly used in this specific separation, and the best configuration during equalization stage. © 2005 American Institute of Chemical Engineers AIChE J, 2005
