Astaxanthin as an adjunct therapy in Alzheimer's disease and multiple sclerosis: neuroprotective mechanisms and future perspective.

Background: Alzheimer's disease (AD) and Multiple sclerosis (MS) are progressive neurodegenerative conditions. AD is characterized by neuroinflammation, plaques, tangles, and synaptic loss, while MS involves inflammatory demyelination. Although AD and MS have different pathogenesis, they may share some neurodegenerative mechanisms, so similar therapeutic strategies could potentially be effective for both.

Secretome of human amniotic membrane stem cells promote recovery and testicular functions through modulating pathway in mice testicular torsion: An experimental study.

Background: Testicular ischemia/reperfusion injury, a significant result of testicular torsion, can lead to the risk of male infertility.

Objective: The current study aimed to evaluate the effect of human amniotic membrane-derived mesenchymal stem cells (hAMSCs) secretome on testicular torsion/detorsion (T/D) in mice.

Materials And Methods: All the experiments were performed in the Anatomy Department of Tehran University of Medical Sciences, Tehran, Iran, during the period of March 2023 to December 2023.

Effects of Quercetin against fluoride-induced neurotoxicity in the medial prefrontal cortex of rats: A stereological, histochemical and behavioral study.

Background: Exposure to high levels of fluoride leads to brain developmental and functional damage. Motor performance deficits, learning and memory dysfunctions are related to fluoride neurotoxicity in human and rodent studies.

Materials And Methods: Here, we evaluated the effects of Quercetin treatment (25 mg/kg) against sodium fluoride-induced neurotoxicity (NaF, 200 ppm) in the medial prefrontal cortex (mPFC) of male adult rats based on oxidative markers, behavioral performances, mRNA expressions, and stereological parameters.

Quercetin as a possible complementary therapy in multiple sclerosis: Anti-oxidative, anti-inflammatory and remyelination potential properties.

Multiple sclerosis (MS) is a complex autoimmune disorder of the central nervous system (CNS) which causes various symptoms such as fatigue, dyscoordination weakness and visual weakness. The intricacy of the immune system and obscure etiology are the main reasons for the lack of a definite treatment for MS. Oxidative stress is one of the most important key factors in MS pathogenesis.

Advances of three-dimensional (3D) culture systems for in vitro spermatogenesis.

The loss of germ cells and spermatogenic failure in non-obstructive azoospermia are believed to be the main causes of male infertility. Laboratory studies have used in vitro testicular models and different 3-dimensional (3D) culture systems for preservation, proliferation and differentiation of spermatogonial stem cells (SSCs) in recent decades. The establishment of testis-like structures would facilitate the study of drug and toxicity screening, pathological mechanisms and in vitro differentiation of SSCs which resulted in possible treatment of male infertility.

Effects of Calorie Restriction on Multiple Sclerosis: A Review of the Preclinical and Clinical Studies.

It has been indicated that calorie restriction (CR) leads to several neuroprotective effects against physiological aging and different neurodegenerative disorders. Unfortunately, the definite therapeutic strategy is not introduced for Multiple sclerosis (MS) as an autoimmune disease of central nervous system (CNS) and researchers are striving to find the best treatment procedures and then optimize them. More recently, several preclinical studies have reported beneficial effects of CR on MS.
