Animal origins free products in cell culture media: a new frontier.

Despite the importance of finding replacements for fetal bovine serum (FBS), very few studies have focused on this subject. Historically, the use of animals and their derivatives in growth, reproduction, and physiological studies has raised several concerns. The supplementation of culture media with FBS, also known as fetal calf serum, continues to be widespread, despite its limitations in quality, reproducibility, and implications for animal welfare.

Production of Cartilaginous Organoids: Potential Opportunities and Challenges, A Review Article.

Damaged articular cartilage has limited self-healing potential and often leads to osteoarthritis (OA), pain, and dysfunction of the affected joint. Autologous and allogenic transplants cannot fully meet the needs of clinical treatment. Two dimensional (2D) and three-dimensional (3D) cell cultures can help to study growth modeling and physiological characteristics of the human body.

Evaluating effect of acrylamide and ascorbic acid on oxidative stress and apoptosis in ovarian tissue of wistar rat.

Acrylamide is one of the undesirable compounds created in food, which leads to oxidative stress. Under normal conditions of the body, there is a balance between the production and elimination of free radicals. Imbalance in this process causes oxidative stress.

The effects of morphine abuse on sperm parameters, chromatin integrity and apoptosis in men.

Objective: Morphine is one of the major psychoactive chemicals in opium that can increase the production of free radicals and thus can negatively affect spermatogenesis. The purpose of this study was to demonstrate the effects of morphine consumption on sperm parameters, DNA integrity and apoptosis in men taking morphine.

Methods: In this case-control study, 30 man abusing morphine (cases) and 30 healthy men (controls) were compared in sperm parameters (count, motility and morphology) and sperm chromatin quality, with Aniline Blue (AB), Toluidine blue (TB) and Chromomycin A3 (CMA3) stains.

Investigation and Comparison of the Effect of TGF-β3, kartogenin and Avocado/Soybean Unsaponifiables on the In-vitro and In-vivo Chondrogenesis of Human Adipose-Derived Stem Cells on Fibrin Scaffold.

Due to the lack of suitable therapeutic approaches to cartilage defect, the objective of this study was to determine the effect of Transforming growth factor-β3 (TGF-β3), avocado/soybean (ASU) and Kartogenin (KGN) on chondrogenic differentiation in human adipose-derived stem cells (hADSCs) on fibrin scaffold. hADSCs seeded in fibrin scaffold and cultured in chondrogenic media. These cells were divided into 4 groups (control, TGF-β3, ASU and KGN).

The effects of sesame oil and different doses of estradiol on testicular structure, sperm parameters, and chromatin integrity in old mice.

Objective: Studies of the effects of estrogens on the male reproductive system have emphasized the role of these hormones in male fertility. Sesame oil has many phytoestrogenic compounds and may improve male fertility. This study investigated the effects of sesame oil and different concentrations of estrogen on sperm parameters and DNA integrity in male mice.

Protective effects of curcumin on chromatin quality, sperm parameters, and apoptosis following testicular torsion-detorsion in mice.

Objective: The chief outcome of testicular torsion in clinical and experimental contexts is testicular ischemia. Curcumin, a compound with anti-inflammatory and antioxidant properties, has fascinated researchers and clinicians for its promise in the treatment of fertility diseases.

Methods: Thirty-five fully grown male mice were randomly classified into five groups: control, sham, testicular torsion, treatment group 1 (testicular torsion+short-term curcumin), and treatment group 2 (testicular torsion+long-term curcumin).

Comparison of TGF-β3 and avocado/soybean unsaponifiable on chondrogenesis of human adipose-derived stem cells on poly (lactic-co-glycolic) acid/ hyaluronic acid hybrid scaffold.

Objectives: Avocado/soybean unsaponifible (ASU) possesses properties including chondroprotective, anticatabolic, and anabolic. The goal behind this research was to detect the effect of ASU and TGF-β3 on the chondrogenesis of human adipose-derived stem cells (hADSCs) on poly (lactic-co-glycolic) acid (PLGA)/ hyaluronic acid (PLGA/HA) hybrid scaffold.

Materials And Methods: First hADSCs were seeded in PLGA/Hyaluronic acid scaffold and cultured in chondrogenic media.

L-Carnitine reduces the negative effects of formalin on sperm parameters, chromatin condensation and apoptosis in mice: An experimental study.

Background: Formalin is commonly applied as an antiseptic and tissue fixative. It has reactive molecules that lead to its cytotoxic effects. According to recent studies, formalin causes a change in the testicular and sperm structure and L-carnitine (LC) acts as an antioxidant to counteract its effects.

Effects of acrylamide in the presence of vitamin E on sperm parameters, chromatin quality, and testosterone levels in mice.

Objective: The present study investigated sperm chromatin quality and testosterone levels in acrylamide-treated mice and the possible protective effects of vitamin E on the fertility potential of spermatozoa.

Methods: Thirty-two adult male mice were divided equally into four groups. Group 1 was the control, group 2 received acrylamide (10 mg/kg, water solution), group 3 received vitamin E (100 mg/kg, intraperitoneal), and group 4 received both acrylamide and vitamin E.

IMSI procedure improves clinical outcomes and embryo morphokinetics in patients with different aetiologies of male infertility.

Our objective was to evaluate the effect of IMSI on embryo kinetics and clinical outcomes in patients with different aetiologies of male infertility. A total of 150 couples with different aetiologies of male infertility were randomly divided into ICSI and IMSI treatment groups (n = 75). ICSI was done accordingly.

Vitamin C attenuates detrimental effects of diabetes mellitus on sperm parameters, chromatin quality and rate of apoptosis in mice.

Objectives: The main goal was to examine the protective effects of vitamin C on sperm parameters, sperm chromatin condensation and apoptosis in experimentally-induced diabetic mice.

Study Design: 28 adult Syrian mice were divided into 4 groups. In Group1, the mice were diabetic that received a single dose of Streptozocin (STZ) (200mg/kg) intra-peritoneally (ip).

Effects of acrylamide on sperm parameters, chromatin quality, and the level of blood testosterone in mice.

Background: Acrylamide (AA) is an important industrial chemical primarily. AA is also found in carbohydrate-rich foods that are prepared at high temperatures, such as French fries and potato chips. It is demonstrated that AA is a carcinogen and reproductive toxin and has ability to induce sperm damage.

Effects of silver nano-particles on sperm parameters, number of Leydig cells and sex hormones in rats.

Background: Nano-particles are extensively employed in most industries. Several studies have been started to explore the probable detrimental effects of nano-particles on human reproduction. However, there is insufficient and controversially evident of effects of silver nano-particles on sperm parameters and other reproductive indices.

Effects of experimentally-induced diabetes on sperm parameters and chromatin quality in mice.

Background: Diabetes mellitus (DM), primary or idiopathic is a chronic disorder of the carbohydrate, lipid and protein metabolism. DM may impact male reproductive function at several levels. It is shown that DM has detrimental effects on sperm parameters in human and experimental animals.
