Introduction: Endocrine disorders such as polycystic ovary syndrome (PCOS) and hypothyroidism can cause infertility. There are evidence that they happen jointly in some circumstances. It still remains unknown, how these two illnesses interact and influence the body. Methods: Accordingly, a five-group was designed, first is the control group, fol...

Pentylenetetrazole (PTZ) is a chemical substance which is largely used for the induction of seizure and epilepsy in the animal model, and it can also, disrupts free radicals balance and cause oxidative stress in the body with a negative impact on memory and learning. In this study, the medicinal plant Buxus hyrcana, was used to evaluate its effect...

Contaminating chemicals can directly affect population density and species diversity in the aquatic ecosystem by altering critical water parameters such as temperature, pH, dissolved oxygen, conductivity, and hardness, as well as dramatically reducing production in the aquaculture industry. High levels of nitrite are often observed in dense aquacu...

Pentylenetetrazole (PTZ) is a chemical substance which largely used for induction of seizure and epilepsy in the animal model, and it can also, disrupts free radicals balance and causes oxidative stress in the body with a negative impact on behavioral statuses like anxiety and depression. In this study, the medicinal plant Buxus hyrcana, was used t...

Introduction: More than 186 million people suffer to infertility worldwide. Polycystic ovary syndrome (PCOS) is the most common cause of chronic anovulation and infertility. PCOS is known as an endocrine disorder in women of marriageable age and is associated with metabolic disorders and dysfunction of the reproductive system. There is also a clear...

Thyme with the scientific moniker of Thymus vulgaris has been used in traditional medicine for treatment of respiratory and gastrointestinal disease. Its extract has also been adopted to treat epilepsy and other central nervous system disorders. To evaluate the effect of T. vulgaris extract (TVE), the experimental model of memory impairment caused...

Several studies have shown that neuropeptide Y (NPY) is considered to be one of the key regulators of the hypothalamic-pituitary-gonadal axis in the mammals. Also, kisspeptin is a powerful upstream regulator of gonadotropin-releasing hormone neurons in the hypothalamus. The present study aims to investigate the effects of the intracerebroventricula...

In the present study, the medicinal plant Tanacetum polycephalum, was used to evaluate its effect on oxidative stress and memory deficit caused by PTZ in the rats. Twenty-four rats were randomly categorized into four groups: control negative under treatment with PTZ (sub-threshold dose 35 mg kg−1 for 1 month), control positive under treatment with...

Aims: A number of studies have shown that neuropeptide Y (NPY) is considered to be one of the key regulators of hypothalamic-pituitary-gonadal (HPG) axis in the mammals. In addition, kisspeptin (encode by Kiss1 gene), neurokinin B (encode by Tac3 gene) and dynorphin (encode by Pdyn gene) (commonly known as KNDy secreting neurons) are a powerful ups...

Epilepsy is one the most prevalent neurological illnesses which affects behavioral statuses like anxiety, depression and balance. Based on the anti-inflammatory and antioxidant properties of Tanacetum polycephalum, its effect on anxiety and depression caused by pentylenetetrazole (PTZ)-kindling in rats was investigated. Methods: In order to prepare...

Introduction: The neuropeptide Y (NPY) in the neural circuits of the hypothalamus has a stimulating effect on reproductive activities in mammals. Kisspeptin (KiSS1) is a quintessential neurotransmitter in the reproductive axis which directly stimulates gonadotropin-releasing hormone neurons in the hypothalamus. The distribution of KiSS1 expressing...

Background and Aim : Epilepsy is the most common chronic neurological disorder disease, and its effect on behavioral statuses like anxiety and depression. In this study, the medicinal plant Stachys lavandulifolia, was used to evaluate its effect on anxiety and depression caused by PTZ in the rat.Methods : Twenty-four rats were randomly allocated to...

Large body of studies showed that the pentylenetetrazol (PTZ) can disrupt free radicals balance and causes oxidative stress in the body with a negative impact on memory and learning. The present study was envisaged to study the effect of Tanacetum polycephalum extract (TPE) in the pentylenetetrazol (PTZ) kindling rat model and its associated learni...

Epilepsy is a common chronic neurodegenerative disorder disease, it can also, affect motor balance. In this study, the medicinal plant Thymus vulgaris, was used to evaluate its effect on motor deficit caused by pentylenetetrazol (PTZ) in the rat.

Introduction: Dopamine inhibits hypothalamus-pituitary-gonadal (HPG) axis. Kisspeptin/ GPR54 signaling pathway increases GnRH/LH release and testosterone secretion. In the present study the effects of interaction between dopamine and kisspeptin on mean serum LH concentrations in rats were investigated. Methods: Forty-five male Wistar rats weighing...

Background The genus Tanacetum is widespread in Europe and Western Asia. It is an important traditional plant which has been used in the treatment of many illnesses. Aim In the present study, the effect of the hydroalcholic extract of Tanacetum polycephalum (henceforth TP) on the animal model of seizure was studied. Methods In this experimental s...

Aims: The genus Buxus grows up widespread in Europe and Western Asia. It is an important traditional plant has been used in the treatment of many illnesses. In the present study, the effect of hydroethanolic extract of Buxus hyrcana Pojark (BHP) on the animal model of seizure was studied. Materials and Methods: In this experimental study, forty-two...

Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) has been identified as the well-known coordinator of intracellular antioxidant defense system. Herein, we aimed to evaluate the effects of Nrf2 silencing on mitochondrial biogenesis markers peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), nuclear respiratory factor-1(N...

Introduction: Numerous studies have demonstrated that kisspeptin, a peptide from the KISS1 gene, plays an important role in regulating the secretion of gonadotropin releasing hormone (GnRH). Also, there is some evidence suggesting that kisspeptin can interact with other neuropeptides for the control of the reproductive axis. In the present study, w...
