Evaluation of antinociceptive effect and pharmacological mechanisms of thiocyanoacetamide in rats.

Objective: Acute pain is the most common type of pain. The aim of the present work was carried out to study the antinociceptive effect and pharmacological mechanisms of thiocyanoacetamide (Thm) in rats exposed to thermal pain stimulus.

Materials And Methods: The anti-nociceptive effect of the newly synthesized compound, Thm was studied in comparison to that of paracetamol (Para), dexamethasone (Dex), and morphine (Morph) at different doses using a hot plate test at a constant temperature of 48.

Modulation of inflammatory mediators involved in the antinociceptive and anti-inflammatory effects of a new thioamide derivative: thiocyanoacetamide.

Inflammatory pain is part of the body's defense mechanism and plays an important role in the healing process. Although some drugs are efficient and intensively used for their potent anti-inflammatory properties, they present problematic side effects. The aim of this study was to evaluate the anti-nociceptive effect of the thiocyanoacetamide (Thm) compared to paracetamol (Para), dexamethasone (Dex) and morphine (Morph) and to study inflammatory mediators on models of acute inflammatory pain in rats using the formalin injection test in the hind paw of rats as chemical stimulus.

In vivo exposure to a new 2-cyano-2-p-nitrophenyl-N-benzylthioamide decreases doxorubicin-triggered structural damages in the mature testis.

The use of doxorubicin (DOX) in clinical practice continues to be challenged by its severe toxicity. DOX cytotoxic activity is not only directed against malignant tumours, given that the treatment will damage healthy tissues as well leading to irreversible injuries. This study aimed to address the in vivo effects of DOX and its co-administration with a new analog of thioamide; thiocyanoacetamide (TA) on the germinal epithelium.

Kefir milk consumption decreases sperm alterations due to the high-fat diet in adult male rats.

Over the past decades, an increase of male infertility through the decrease of sperm count has been noted. It has been suggested that environmental factors and lifestyle could a negative impact over sperm quality. Among these factors, the consumption of foods high in fat, which leads to overweight and obesity, can negatively influence fertility.

Grape Seed Flour Extends Longevity by Improving Multi-Organ Dysfunction and Age-Associated Oxidative Stress and Inflammation in Healthy Rat.

According to the free-radical theory of aging, accumulation of reactive oxygen species (ROS) within mitochondria throughout life span leads to impairment of the main biological macromolecules as DNA, lipids, and proteins, which might be at the basis of premature aging. One way to test experimentally such a hypothesis consists in intervention studies using antioxidant nutrients aimed at limiting or inhibiting ROS production that should be able to reduce the aging rate and disease pathogenesis. Grape seed flour (GSF) contains a high level of phytochemicals among which bioactive polyphenols exhibit numerous biological properties and beneficial health effects as antioxidant, anti-inflammatory, anticarcinogenic, multi-organ (heart, liver, kidney, and brain among others) protective.

Date seeds alleviate behavioural and neuronal complications of metabolic syndrome in rats.

Unhealthy dietary habits can play a crucial role in metabolic damages, promoting alteration of neural functions through the lifespan. Recently, dietary change has been perceived as the first line intervention in prevention and/or treatment of metabolic damages and related diseases. In this context, our study was designed to assess the eventual therapeutic effect of date seeds administration on memory and learning and on neuronal markers in a rat Metabolic Syndrome model.

Acute respiratory distress syndrome: a life threatening associated complication of SARS-CoV-2 infection inducing COVID-19.

Acute Respiratory Distress Syndrome (ARDS) is a form of respiratory failure in human. The number of deaths caused by SARS-CoV-2 infection inducing this severe pneumonia (ARDS) is relatively high. In fact, COVID-19 might get worsen in ARDS and provoke respiratory failure.

Matrix metalloproteinase-7 could be a predictor for acute inflammation in psoriatic patients.

Purpose: The pathogenesis of psoriasis is characterized by a disruption of extracellular matrix (ECM) in which matrix metalloproteinases (MMPs) participate actively. We aimed to determine MMP-7 level and its association with the inflammatory response in order to determine its usefulness as a biomarker for psoriasis prediction. We also aimed to determine its distribution in uninvolved and involved psoriatic skin to evaluate the probable role of MMP-7 in psoriasis pathogenesis.

A new thiocyanoacetamide (2-cyano-2-p-nitrophenyl-N-benzylthioamide) reduces doxorubicin-induced in vitro toxicity in Sertoli cells by decreasing apoptosis and autophagy.

Despite conflicting data on doxorubicin (DOX) reproductive toxicity, its chemotherapeutic potential sustains its use to treat different types of cancer. This work was designed to study the protective effect of a newly synthesized thiocyanoacetamide (TA), in comparison with selenium (Se), against doxorubicin-induced in vitro toxicity in rat Sertoli cells (SCs). DOX was administered alone or in combination with Se or TA.

A new Thiocyanoacetamide protects rat sperm cells from Doxorubicin-triggered cytotoxicity whereas Selenium shows low efficacy: In vitro approach.

Doxorubicin (DOX) exhibits a wide-ranging spectrum of antitumor activities which maintain its clinical use despite its devastating impact on highly proliferating cells. The present work was designed to develop a new approach which aims to protect male germ cells from DOX cytotoxicity. Thus, an assessment of the protective potential of a new thioamide analog (thiocyanoacetamide; TA) compared to selenium (Se) was performed in rat sperms exposed to DOX in vitro.

This work presents the development and validation of simple, rapid and accurate spectrophotometric method for the analysis of Thm derivatives in pure form and in plasma. This spectrophotometric method has not been used before for determination of Thm.

Recent studies have showed cytotoxic effects of the electronic cigarette and its recharge e-liquid, in vitro. The present study was designed to evaluate e-cigarette liquid nephrotoxicity in rats.

Grape seed and skin extract protects against arsenic trioxide induced oxidative stress in rat heart.

Arsenic is a metalloid found in water, soil, and air from natural and anthropogenic sources, and is commonly found in inorganic as well as organic forms. The clinical use of arsenic trioxide (AsO) in the treatment of acute promyelocytic leukemia (APL) is limited by its cardiotoxic side effects. Grape seed and skin extract (GSSE) is a polyphenolic mixture with antioxidant properties.

Autophagy mediates neutrophil responses to bacterial infection.

Neutrophils constitute the first line of cellular defense against pathogens and autophagy is a fundamental cellular homeostasis pathway that operates with the intracellular degradation/recycling system. Induction of the autophagic process in neutrophils, in response to invading pathogens, constitutes a crucial mechanism in innate immunity. Exploration of autophagy has greatly progressed and diverse strategies have been reported for studying this molecular process in different biological systems; especially in infectious and inflammatory diseases.

Protective effect of grape seed and skin extract against high-fat diet-induced liver steatosis and zinc depletion in rat.

Background: Obesity is a tremendous public health problem, characterized by ectopic deposition of fat into non-adipose tissues as liver generating an oxidative stress that could lead to steato-hepatitis. Grape seed and skin extract (GSSE) is a complex mixture of polyphenolics exhibiting robust antioxidative properties.

Aim: We hypothesize that GSSE could protect the liver from fat-induced lipotoxicity and have a beneficial effect on liver function.

Walker 256/B malignant breast cancer cells disrupt osteoclast cytomorphometry and activity in rats: modulation by α-tocopherol acetate.

We examined the effects of vitamin E supplementation (VES) on osteoclast (OC) resorbing activity and cytomorphometry in Walker 256/B tumor osteolytic rats. Twenty-four aged male rats were randomized into 3 groups: 6 were sham operated; 9 were injected in the right hind limb with Walker 256/B cells (W256 group); and 9 were injected as above and supplemented with VE (45mg/kg BW) (W256VE group). Twenty days later, bone mass (BV/TV) and some microarchitectural parameters were assessed.

Grape seed and skin extract alleviates high-fat diet-induced renal lipotoxicity and prevents copper depletion in rat.
