Department of Biology, University of Turku, 20014, Turku, Finland.
Alpine and Arctic treelines are assumed to be shifting toward higher latitudes and altitudes as a consequence of climate warming. Here, we compared the survival and growth of 1264 silver birch (Betula pendula Roth.) trees representing nine half-sib families.

Purpose: This study aimed to evaluate the effectiveness of single versus group culture strategies for cumulus-oocyte complexes (COCs) derived from early antral follicles (EAFs), with the goal of optimizing culture conditions to increase oocyte availability for assisted reproductive technologies.
Methods: COCs isolated from EAFs (350-450 µm) from sheep ovaries were cultured in TCM199 medium supplemented with 0.15 µg/mL Zn as zinc sulfate, 10 IU/mL FSH, 10 ng/mL estradiol, 50 ng/mL testosterone, 50 ng/mL progesterone, and 5 µM Cilostamide.
Expression profile analysis of estrous-phased ovarian tissue of high and low prolific lines of inbred Swiss albino mice.

Division of Animal Genetics, ICAR-Indian Veterinary Research Institute (ICAR-IVRI), Izatnagar, Bareilly 243 122, Uttar Pradesh, India.
Background: Litter size in mice is an important fitness and economic feature that is controlled by several genes and influenced by non-genetic factors too. High positive selection pressure in each generation for Litter size at birth (LSB), resulted in the development of high and low prolific lines of inbred Swiss albino mice (SAM). Despite uniform management conditions, these lines showed variability in LSB across the generation.

Objective: To compare the number and outcomes of elective fertility preservation (FP) before and after the Covid-19 outbreak.
Methods: This retrospective study of 574 women who underwent elective FP between 01/2017-12/2021 included 123 women who underwent the procedure before and 451 who underwent it after the Covid-19 outbreak. The change in the number of women who underwent the procedure each month before and after the pandemic was calculated.
Analyzing free fatty acids in seminal plasma from asthenozoospermia patients undergoing antioxidant therapy.

January 2025
Integrative Oncology Department, Breast Cancer Research Center, Motamed Cancer Institute, ACECR, Tehran, Iran.
Objective: Different aspects of the functions of free fatty acid (FFA) in seminal plasma and their implications on male fertility are known. However, the profile of FFA in seminal plasma in asthenozoospermic patients following antioxidant therapy has not been studied.
Methods: In this case-control study, the total antioxidant capacity (TAC) and FFA profile of the seminal plasma were determined in 80 patients (29 normozoospermic volunteers and 51 asthenozoospermic men) who were treated with antioxidants for three months.
