Conifers have long been recognized for their therapeutic potential in different disorders. Alkaloids, terpenes and polyphenols are the most abundant naturally occurring phytochemicals in these plants. Here, we provide an overview of the phytochemistry and related commercial products obtained from conifers. The pharmacological actions of different phytochemicals present in conifers against bacterial and fungal infections, cancer, diabetes and cardiovascular diseases are also reviewed. Data obtained from experimental and clinical studies performed to date clearly underline that such compounds exert promising antioxidant effects, being able to inhibit cell damage, cancer growth, inflammation and the onset of neurodegenerative diseases. Therefore, an attempt has been made with the intent to highlight the importance of conifer-derived extracts for pharmacological purposes, with the support of relevant in vitro and in vivo experimental data. In short, this review comprehends the information published to date related to conifers’ phytochemicals and illustrates their potential role as drugs.

Synaptic plasticity provides a record of neuronal activity and is a likely basis for memory. The early apparent simplicity of the process of synaptic plasticity has been lost in a flood of experimental data that now implicates some 200 signaling molecules in cellular memory. It is now clear that these signaling networks perform surprisingly sophisticated cellular decisions that weigh factors such as input patterns, location of stimulus, history of activity, and context. Computer models have followed experiments into this maze of molecular detail, often matching closely with their experimental counterparts, but perhaps losing simplicity in the process. Here, we suggest that the merger of models and experiment have begun to restore the earlier simplicity by outlining a few key functional roles for signaling networks in synaptic plasticity. In this review, we discuss the current state of understanding of synaptic plasticity in terms of models and experiments.

Pregnancy And Delivery

The objective: to study the structure and frequency of complications of pregnancy, deliveries and perinatal outcomes in three groups of women: women with infertility and obesity, treated by application of in vitro fertilization (hereinafter IVF), pregnant women after IVF application with normal body weight, and pregnant women on the background of obesity which did not have an infertility in past history. Materials and methods. A retrospective analysis of 221 case histories of pregnancies and labors in women who were treated and gave birth in the Pregnancy and delivery pathology Department of SI «Institute of Pediatrics, Obstetrics and Gynecology named after Acad. O. M. Lukyanova of NAMS of Ukraine» for 2012 – 2016 years was carried out. Results. The overwhelming majority of pregnant women after IVF on the background of obesity are primaparas, who have a complicated obstetric history, hormonal changes in the form of progesterone deficiency predominantly and chronic inflammatory processes. Pregnancy with a combination of infertility, treated by the means of IVF application, and obesity, in most cases is accompanied by a long-term threat of termination of pregnancy (48.8%), threatening preterm deliveries (56%), placental dysfunction (41.5%), premature rupture of the amniotic membranes (41.5%), other problems during pregnancy, at the same time, every second woman (58.5%) had a combination of several complications, and required a long-term and repeated inpatient treatment (53.7%). The specific gravity of surgical delivery was 90%, and 16.2% of such deliveries were complicated by pathological blood loss. The number of preterm deliveries was 17.1%, with perinatal losses up to 11.3‰. Among full-term newborns 21.3% of newborns had malnutrition of the I degree and 17% of them had hypoxic-ischemic lesion of CNS. Conclusion. The course of pregnancy, delivery and the postpartum period in the studied contingent of women has a significant frequency of complications, mainly the coinciding ones, which affects on the consequences of perinatal outcomes and requires further study of this problem and the development of differentiated algorithms for antenatal observation. Key words: pregnancy, obesity, in vitro fertilization, complications, delivery, newborn.

Standardized swim-up trials are used in in vitro fertilization clinics to select particularly motile spermatozoa in order to increase the probability of a successful fertilization. Such trials demonstrate that sperm with longer telomeres have higher motility and lower levels of DNA damage. Regardless of whether sperm motility, and successful swim-up to fertilization sites, is a direct or correlational effect of telomere length or DNA damage, covariation between telomere length and sperm performance predicts a relationship between telomere length and probability of paternity in sperm competition, a prediction that for ethical reasons cannot be tested on humans. Here, we test this prediction in sand lizards ( Lacerta agilis ) using experimental data from twice-mated females in a laboratory population, and telomere length in blood from the participating lizards. Female identity influenced paternity (while the mechanism was not identified), while relatively longer male telomeres predicted higher probability of paternity. We discuss potential mechanisms underpinning this result.
