The aim of this study is evaluation of the efficacy of Artaderm herbal ointment containing the Henna (Lawsonia inermis) extract, Linseed (Linum usitatissimum) oil, and Honey Wax on wound healing in the rat with second-degree burn wounds. The Artaderm ointment had an effective role in controlling burn wound infections due to its antimicrobial and anti-inflammatory properties. In this study, 64 male Wistar rats were randomly divided into 8 groups (n = 8). Four groups received Artaderm, 1% Silver Sulfadiazine (SSD 1%), Cod Liver Oil and Fundermol (Alpha) ointments which used in common practices for burn injuries. Another three groups received Henna, Linseed, and Honey Wax alone and a control group that just underwent a second-degree burn injury without any treatments. A second-degree burn was formed on the back of each rat and dressed daily with one of the agents. Burn wounds were macroscopically and microscopically evaluated on the 7th, 14th, and 21st day after burn induction. Rats treated with the Artaderm ointment had significantly faster wound contraction as well as shorter healing time than the rest groups. No scar was observed in rats treated with the Artaderm ointment on the 21st day, while this level of improvement was not observed in other groups at the same time. More than 90% of wounds were healed after on the 14th day in rats treated with Artaderm (94.10 ± 0.18) and Alpha (92.05 ± 0.23) ointments. According to these findings, it can be concluded that Artaderm herbal ointment can be used as a proper alternative for healing of wounds in second-degree burns.
Parkinson&amp... more Parkinson's disease (PD) is a chronic neurodegenerative movement disorder characterized by the progressive and massive loss of dopaminergic neurons by neuronal apoptosis in the substantia nigra pars compacta and depletion of dopamine in the striatum, which lead to pathological and clinical abnormalities. A numerous of cellular processes including oxidative stress, mitochondrial dysfunction, and accumulation of α-synuclein aggregates are considered to contribute to the pathogenesis of Parkinson's disease. A further understanding of the cellular and molecular mechanisms involved in the pathophysiology of PD is crucial for developing effective diagnostic, preventative, and therapeutic strategies to cure this devastating disorder. Preconditioning (PC) is assumed as a natural adaptive process whereby a subthreshold stimulus can promote protection against a subsequent lethal stimulus in the brain as well as in other tissues that affords robust brain tolerance facing neurodegenerative insults. Multiple lines of evidence have demonstrated that preconditioning as a possible neuroprotective technique may reduce the neural deficits associated with neurodegenerative diseases such as PD. Throughout the last few decades, a lot of efforts have been made to discover the molecular determinants involved in preconditioning-induced protective responses; although, the accurate mechanisms underlying this…

However, the limitations of host toxicity, bioactivity and column purification have impaired production in mass quantities. In this study, short cationic peptides were produced in aggregated inclusion bodies by double fusion with a central pro-tein that has anti-cancer activity. The anticancer peptides Tachiplicin I (TACH) and Latarcin 1 (LATA) were fused with the N- and C-terminus of the MAP30 protein, respectively. We successfully produced the recombinant TACH-MAP30-LATA protein and MAP30 alone in E. coli that represented 59 % and 68 % of the inclusion bodies. The purified form of the inclu-sion bodies was prepared by eliminating host cell proteins through multiple washing steps and semi-solubilization in alkaline buffer. The purified active protein was recovered by inclu-sive solubilization at pH 12.5 in the presence of 2 M urea and refolded in alkaline buff...

Dysregulation and, in particular, overproduction of this gene has been found to increase susceptibility to a variety of human diseases such as cancer. The aim of this study is to investigate the association of single nucleotide polymorphism (SNP) in TNF-α −308 promoter and the risk of oral cancer among the Malaysian Indian and Indigenous population.The study included 143 confirmed oral squamous cell carcinoma (OSCC) (mean age = 63.69 ± 12.84) and 79 healthy controls (mean age = 50.43 ± 16.35). The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to analyze TNF-α −308 promoter polymorphism, which were confirmed by direct sequencing. Chi-square, simple logistic regression and stratified analysis were performed using the SPSS (ver 15.0) to study the role of TNF-α polymorphism in modulating the risk of oral cancer.

In this regard, effective strategies to control epilepsy resulting from neuroinflammation could be targeted. Based on the available data, preconditioning (PC) with low dose lipopolysaccharide (LPS) through the regulation of the TLR4 signaling pathway provides neuroprotection against subsequent challenge with injury in the brain. To test this, we examined the effects of a single and chronic brain LPS PC, which is expected to lead to reduction of inflammation against epileptic seizures induced by electroconvulsive shock (ECS). A total of 60 male Sprague Dawley rats were randomly assigned to five groups: control, vehicle (single and chronic), and LPS PC (single and chronic). We first recorded the data regarding the behavioral and histological changes. We further investigated the alterations of gene and protein...

Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic connections, referred to as long-term potentiation (LTP) and long-term depression (LTD) respectively. Such phenomena have been described in a variety of model organisms, which are used to study molecular, structural, and functional aspects of synaptic plasticity. This review originated from the first International Society for Neurochemistry (ISN) and Journal of Neurochemistry (JNC) Flagship School held in Alpbach, Austria (Sep 2016), and will use its curriculum and discussions as a framework to review some of the current knowledge in the field of synaptic plasticity. First, we describe the role of plasticity during development and the persistent changes of neural circuitry occurring when sensory input is altered during critical developm...

Despite significant progress in the development of antiepileptic therapies over the previous 3 decades, a need still exists for novel therapies. We screened an in-house library of small molecules targeting the NMDA receptor. A novel indolyl compound, 2-(1,1-Dimethyl-1,3-dihydro-benzo[e]indol-2-ylidene)-malonaldehyde, (DDBM) showed the best binding with the NMDA receptor and computational docking data showed that DDBM antagonised the binding sites of the NMDA receptor at lower docking energies compared to other molecules. Using a rat electroconvulsive shock (ECS) model of epilepsy we showed that DDBM decreased seizure duration and improved the histological outcomes. Our data show for the first time that indolyls like DDBM have robust anticonvulsive activity and have the potential to be developed as novel anticonvulsants.

Neurodegeneration is the umbrella term for the progressive death of nerve cells and loss of brain tissue. Because of their high energy requirements, neurons are especially vulnerable to injury and death from dysfunctional mitochondria. Widespread damage to mitochondria causes cells to die because they can no longer produce enough energy. Several lines of pathological and physiological evidence reveal that impaired mitochondrial function and dynamics play crucial roles in aging and pathogenesis of neurodegenerative diseases. As mitochondria are the major intracellular organelles that regulate both cell survival and death, they are highly considered as a potential target for pharmacological-based therapies.

Methods Aspirated samples from the lesions of 86 patients with confirmed leishmaniasis used for direct smear preparation. The samples are prepared and cultured in the Novy-MacNeal-Nicolle and Roswell Park Memorial Institute-1640 culture mediums. After extraction of DNA by using phenol-chloroform, parasite kintoplast DNA gene amplification was done by using PCR. The electrophoresis pattern of each species was compared with standard species of Leishmania tropica (L. tropica) and Leishmania major (L. major). Results Results of PCR patterns of kintoplast DNA gene suggested that two types of L. tropica and L. major isolated from leishmaniasis patients in Sabzevar and their findings indicated that both species of parasites, L. tropica and L. major are prevalent in Sabzevar. Conclusions According to this information, Sabzevar can be divided in two focal points of dry and dry-wet in terms of leishmaniasis, while it was previously known as the dry focal point. Likewise a significant relationship observed between Leishmania species to time distribution, type of lesion, amount of parasites and infection districts.

Cell proliferation and migration are significantly depressed during hibernation state. Many studies believe some factors in the plasma of hibernating animals cause these effects. This study aimed to assess the anti-cancer effects of hibernating common carp (Cyprinus carpio) plasma on 4T1 cancer cells in vitro and in vivo. The effect of hibernating plasma on cell viability, morphology, migration, apoptosis rate, and cell cycle distribution of 4T1 cells was investigated in vitro and in vivo. Hibernating plasma at a concentration of 16 mg/ml significantly reduced the viability of 4T1 cancer cells, without any toxicity on L929 normal fibroblast cells. It could change the morphology of cancer cells, induced apoptosis and cell cycle arrest at the G2/M phase, and inhibited migration. Furthermore, intratumoral injection of hibernating plasma (200 µl, 16 mg/ml) in the tumor-bearing mice caused a significant inhibition of 4T1 breast ...

Our data show for the first time that indolyls like DDBM have robust anticonvulsive activity and have the potential to be developed as novel anticonvulsants. Epilepsy affects around 50 million people worldwide 1. The last two decades have seen significant advances in new therapies for epilepsy including new antiepileptic drugs (AED) 2 , surgery 3 , cell therapy 4 , gene therapy 5 , and brain stimulation 6. However, approximately one-third of people with epilepsy continue to have seizures that are intractable and experience intolerable side effects to currently available treatments 7. Therefore, despite recent therapeutic advances, epilepsy still continues to be a major health problem and more therapies are needed including new anticonvulsant drugs. Although our understanding of epilepetogenesis has improved over the years, the complex array of pathological processes that lead to epilepsy are still largely unknown. Recently, evidence supporting the role of neuroinflammation 8 , oxidative stress and reactive oxygen species (ROS) production 9 , mitochondrial dysfunction 10 , damage of blood–brain barrier (BBB) 11 , as well as failure in the regulation of Gamma-aminobutyric acid (GABA) has been put forth 12. It has also been shown that N-methyl-D-aspartate receptors (NMDAR) are important subtype of the glu-tamate receptors which play a crucial role in both pathological and physiological processes 13. NMDARs are glutamate-gated cation channel that mediates excitatory neurotransmission in the central nervous system (CNS) 14. Activation of the NMDARs plays an important role in the pathogenesis of a wide range of neuro-pathological disorders including schizophrenia, stroke, depression, multiple sclerosis, Huntington's disease 15 , Parkinson's disease 16 , Alzheimer's disease 17,18 , and epilepsy 15,19. In epilepsy, NMDA induces seizures in a different pattern compared and causes different long term consequences compared to kainic acid 20. Signalling activation in neurons results in a rapid increase of NMDA receptor, leading to excitotoxic damage through consequent

Our data show for the first time that indolyls like DDBM have robust anticonvulsive activity and have the potential to be developed as novel anticonvulsants. Epilepsy affects around 50 million people worldwide 1. The last two decades have seen significant advances in new therapies for epilepsy including new antiepileptic drugs (AED) 2 , surgery 3 , cell therapy 4 , gene therapy 5 , and brain stimulation 6. However, approximately one-third of people with epilepsy continue to have seizures that are intractable and experience intolerable side effects to currently available treatments 7. Therefore, despite recent therapeutic advances, epilepsy still continues to be a major health problem and more therapies are needed including new anticonvulsant drugs. Although our understanding of epilepetogenesis has improved over the years, the complex array of pathological processes that lead to epilepsy are still largely unknown. Recently, evidence supporting the role of neuroinflammation 8 , oxidative stress and reactive oxygen species (ROS) production 9 , mitochondrial dysfunction 10 , damage of blood–brain barrier (BBB) 11 , as well as failure in the regulation of Gamma-aminobutyric acid (GABA) has been put forth 12. It has also been shown that N-methyl-D-aspartate receptors (NMDAR) are important subtype of the glu-tamate receptors which play a crucial role in both pathological and physiological processes 13. NMDARs are glutamate-gated cation channel that mediates excitatory neurotransmission in the central nervous system (CNS) 14. Activation of the NMDARs plays an important role in the pathogenesis of a wide range of neuro-pathological disorders including schizophrenia, stroke, depression, multiple sclerosis, Huntington's disease 15 , Parkinson's disease 16 , Alzheimer's disease 17,18 , and epilepsy 15,19. In epilepsy, NMDA induces seizures in a different pattern compared and causes different long term consequences compared to kainic acid 20. Signalling activation in neurons results in a rapid increase of NMDA receptor, leading to excitotoxic damage through consequent

Neurodegeneration is the umbrella term for the progressive death of nerve cells and loss of brain tissue. Because of their high energy requirements, neurons are especially vulnerable to injury and death from dysfunctional mitochondria. Widespread damage to mitochondria causes cells to die because they can no longer produce enough energy. Several lines of pathological and physiological evidence reveal that impaired mitochondrial function and dynamics play crucial roles in aging and pathogenesis of neurodegenerative diseases. Since mitochondria are the major intracellular organelles that regulate both cell survival and death, they are highly considered as a potential target for pharmacological-based therapies. The purpose of this review is to present the current status of our knowledge and understanding of the involvement of mitochondrial dysfunction in pathogenesis of neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS) and the importance of mitochondrial biogenesis as a potential novel therapeutic target for their treatment. Likewise we highlight a concise overview of the key roles of mitochondrial electron transport chain (ETC) complexes as well as mitochondrial biogenesis regulators regarding those diseases.
