Sex-specific contrasting role of BECLIN-1 protein in pain hypersensitivity and anxiety-like behaviors.

Chronic pain is a debilitative disease affecting 1 in 5 adults globally, and is a major risk factor for anxiety (Goldberg and McGee, 2011; Lurie, DI., 2018). Given the current dearth of available treatments for both individuals living with chronic pain and mental illnesses, there is a critical need for research into the molecular mechanisms involved in order to discover novel treatment targets.

Circadian Influences on Myocardial Ischemia-Reperfusion Injury and Heart Failure.

The impact of circadian rhythms on cardiovascular function and disease development is well established, with numerous studies in genetically modified animals emphasizing the circadian molecular clock's significance in the pathogenesis and pathophysiology of myocardial ischemia and heart failure progression. However, translational preclinical studies targeting the heart's circadian biology are just now emerging and are leading to the development of a novel field of medicine termed circadian medicine. In this review, we explore circadian molecular mechanisms and novel therapies, including (1) intense light, (2) small molecules modulating the circadian mechanism, and (3) chronotherapies such as cardiovascular drugs and meal timings.

Moderate and high-intensity interval training protect against diabetes-induced modulation of hepatic CD86 and CD206 expression associated with the amelioration of insulin resistance and inflammation in rats.

Diabetes Mellitus (DM) can damage the function of metabolic tissues, including the liver. Liver macrophages are the first responders to tissue damage or exercise. We sought to determine whether eight weeks of interval training (HIIT & MIIT) protect against diabetes-induced modulation of hepatic CD86 and CD206 expression associated with the amelioration of insulin resistance and inflammation in rats.

Small Molecule Differentiate PDX1-Expressing Cells Derived from Human Endometrial Stem Cells on PAN Electrospun Nanofibrous Scaffold: Applications for the Treatment of Diabetes in Rat.

In this study, we designed an engineered tissue and transplanted it to an animal model, trying to take an effective step toward meeting the needs of diabetic patients. Here, human endometrial cells were differentiated into PDX1-expressing cells using a small molecule of Y-27632 on polyacrylonitrile (PAN) electrospun scaffolds and transplanted into diabetic rats. PAN nanofibers were made by electrospinning.

Attenuation of heat stress-induced spermatogenesis complications by betaine in mice.

High temperatures can induce oxidative stress, impairment of spermatogenesis, and reduction of sperm quality and quantity concomitant with transient periods of partial or complete infertility in male mammals. Promising beneficial effects of betaine supplementation on the epididymal spermatozoa have been reported in experimental studies; however, its effects on testicular heat stress (HS)-induced impairment have yet to be determined. In the present study, betaine (Bet) was orally administrated (250 mg/kg day) during a 14-day period, before (Bet + HS group) or after (HS + Bet group) induction of testicular HS in 7-9 week-old male mice.

Aloe vera gel improves behavioral deficits and oxidative status in streptozotocin-induced diabetic rats.

Oxidative stress has a major role in progression of diabetes-related behavioral deficits. It has been suggested that Aloe vera has anti-diabetic, antioxidative, and neuroprotective effects. The present study was designed to determine the effects of Aloe vera gel on behavioral functions, oxidative status, and neuronal viability in the hippocampus of streptozotocin (STZ)-induced diabetic rats.

Effect of natural neosporosis on bull sperm quality.

Neospora is one of the protozoans that can infect the male and female's reproduction system. Despite the existence of N. caninum in the genitalia, its effect on sperm characteristics was not studied yet.

The Aqueous Extract of Portulaca Oleracea Ameliorates Neurobehavioral Dysfunction and Hyperglycemia Related to Streptozotocin-Diabetes Induced in Ovariectomized Rats.

Diabetes mellitus is one of the most common causes of neuropathy. Although antioxidant and antidiabetic effects of the aqueous extract of purslane (Portulaca oleracea) (AEOP) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of AEOP in diabetes induced animals. Thirty ovariectomized (OVX) female Wistar rats were randomly divided into 3 groups of control, Dia and Dia+AEOP.

Induced adverse effects of prenatal exposure to silver nanoparticles on neurobehavioral development of offspring of mice.

Steadily increased use of silver nanoparticles (Ag-NPs), has increased the amount of its exposure to humans and animals. Current scarce knowledge about the influences of prenatal exposure to Ag-NPs on postnatal outcomes, motivated us to investigate whether being exposed to it during pregnancy has any effects on neurobehavioral development of the adult offspring. Thirty virgin female NMRI mice were mated and treated subcutaneously once every three days from gestation day 3 until delivery, by 0, 0.

Effects of prenatal exposure to single-wall carbon nanotubes on reproductive performance and neurodevelopment in mice.

Carbon nanotubes with extraordinary properties may become a novel drug and gene delivery tool in nanomedicine; however, insufficient information is available regarding their biosafety. Therefore, this work was performed to study the effect of prenatal exposure of single-walled carbon nanotubes (SWCNTs) on reproductive and neurobehavioral endpoints in mice. Thirty pregnant female mice were assigned to three groups (n = 10 for each group).

Cannabinoid system of the lateral septum in the modulation of anxiety-like behaviors in rats.

Backgrounds: A large body of evidence suggests that the cannabinoid CB1 receptor plays a key role in the regulation of emotional behaviors. The present study was designed to evaluate the effects of CB1 agonist and antagonist on anxiety-like behaviors in the lateral septum (LS) region of the rat brain using elevated plus maze test.

Methods: Rats were anesthetized with ketamine and xylazine and special cannulas were inserted stereotaxically into the LS region.

Effects of sesame oil on the reproductive parameters of diabetes mellitus-induced male rats.

Purpose: The purpose of the present study was to investigate the effect of sesame oil on the reproductive parameters of diabetic male Wistar rats.

Materials And Methods: The adult male rats in a split plot design were divided into normal (n=10), normal 5% (n=5; 5% sesame oil enriched diet), diabetic (Streptozocin induced diabetes; n=9), diabetic 5% (n=9; 5% sesame oil enriched diet), and diabetic 10% (n=9; 10% sesame oil enriched diet) groups. Diet supplementation continued for 56 days.

The effect of butter oil on avoidance memory in normal and diabetic rats.

Objectives: Since diabetes mellitus is accompanied by cognitive impairment in diabetic patient and animal models and since lipids play important roles in neuronal membrane composition, structure and function; we intended to evaluate the effect of dietary butter oil on passive avoidance memory of streptoztosin (STZ)-induced diabetic rats in this study.

Materials And Methods: THIRTY SIX ADULT MALE RATS WERE RANDOMLY ALLOCATED TO FOUR EQUAL GROUPS: normal (N) and diabetic control (D) groups with free access to regular rat diet; but the diet of normal butter oil (NB) and diabetic butter oil (DB) groups was supplemented with 10% butter oil. Diabetes in D and DB groups was induced by intravenous (i.

Biosafety of multiwalled carbon nanotube in mice: a behavioral toxicological approach.

Multiwalled carbon nanotubes (MWCNTs) with unique chemical and electromechanical properties are ideal candidates for the development of drug delivery platforms. The scarce knowledge for the effects of exposure to MWCNTs during pregnancy on postnatal outcomes motivated us to investigate whether intraperitoneal injections (i.p.
