H T Tang, F Zhu
The stress response is a preexisting and adaptive behavioral mode of all living beings, which may bring deleterious consequences of dysfunction or failure of tissue and organ. This article aims to elaborate theories of stress response, summarize the manifestation and mechanism of acute stress response in critically burned patients, and help to improve clinical curative efficacy and prognosis of these patients by physiological, psychological and pharmacological methods.

BACKGROUND: Chronic anal fissures (CAF) are frequently encountered in coloproctology clinics. Chemical sphincterotomy with pharmacological agents is recommended as first-line therapy. Topical nitrates (TN) heal CAF effectively but recurrences are common. An alternative treatment modality is injection of botulinum toxin (BT) into the anal sphincter. We aimed to perform an updated systematic review and meta-analysis to compare the effectiveness of BT and TN in the management of CAF. METHODS: PubMed, EMBASE and Cochrane databases were searched for relevant articles from inception until March 2017...

Nutrient sensing mechanisms have emerged as the fringe articulating nutritional needs with dietary choices. Carbohydrate, amino acid, fatty acid, mineral, and water sensing receptors are highly conserved across mammals and birds, consisting of a repertoire of 22 genes known to date. In contrast, bitter receptors are highly divergent and have a high incidence of polymorphisms within and between mammals and birds and are involved in the adaptation of species to specific environments. In addition, the expression of nutrient sensing genes outside the oral cavity seems to mediate the required decision-making dialogue between the gut and the brain by translating exogenous chemical stimuli into neuronal inputs, and vice versa, to translate the endogenous signals relevant to the nutritional status into specific appetites and the control of feed intake...

Mammalian target of rapamycin (mTOR) signaling pathway controls cell energy metabolism. There is an interplay between mTOR and proinflammatory signaling pathways, supporting the role of the pathway in the pathogenesis of inflammatory diseases. Inhibition of mTOR signaling using specific pharmacological inhibitors could offer therapeutic promise in several inflammatory-associated diseases. In this review, we summarize recent findings on the regulatory effects of mTOR signaling on inflammation and the therapeutic potency of mTOR pharmacological inhibitors in the treatment of inflammatory diseases including cancer, neurodegenerative diseases, atherosclerosis, sepsis and rheumatoid arthritis for a better understanding and hence a better management of these diseases...

BACKGROUND: Skeletal muscle spasticity is a major physical complication resulting from traumatic brain injury (TBI), which can lead to muscle contracture, joint stiffness, reduced range of movement, broken skin and pain. Treatments for spasticity include a range of pharmacological and non-pharmacological interventions, often used in combination. Management of spasticity following TBI varies from other clinical populations because of the added complexity of behavioural and cognitive issues associated with TBI...

Background: Imatinib and second-generation tyrosine kinase inhibitors (TKIs) nilotinib and dasatinib have statistically significantly improved the life expectancy of chronic myeloid leukemia (CML) patients; however, resistance to TKIs remains a major clinical challenge. Although ponatinib, a third-generation TKI, improves outcomes for patients with BCR-ABL-dependent mechanisms of resistance, including the T315I mutation, a proportion of patients may have or develop BCR-ABL-independent resistance and fail ponatinib treatment...

Withanolides are a collection of naturally occurring, pharmacologically active, secondary metabolites synthesised in medicinally important plant, Withania somnifera. These bioactive molecules are C28-steroidal lactone triterpenoids and their synthesis is proposed to take place via the mevalonate (MVA) and 2-C-methyl-D-erythritol-4-phosphate (MEP) pathways through the sterol pathway using 24-methylene cholesterol as substrate flux. Although the phytochemical profiles as well as pharmaceutical activities of Withania extracts have been well studied, limited genomic information and difficult genetic transformation have been major bottleneck towards understanding the participation of specific genes in withanolide biosynthesis...

Increased toxicant exposure and resultant environmentally-induced diseases are a tradeoff of industrial productivity. Dioxin (TCDD: 2,3,7,8 tetrachlorodibenzo-p-dioxin), a ubiquitous by-product is associated with a spectrum of diseases including endometriosis, a common, chronic disease in women. TCDD activates cytochrome p450 (CYP) metabolic enzymes, which alters organ function to cause disease. In contrast, the transcription factor, Krüppel-Like Factor (KLF) 11 represses these enzymes via epigenetic mechanisms...

Vitexin, a natural flavonoid found in many medicinal plants, is well known for its rich pharmacological activities. However, the poor water solubility of vitexin has limited its therapeutic application. The aim of this study was to prepare the nanoparticles of vitexin by combining the antisolvent precipitation (ASP) and high pressure homogenization (HPH) approaches followed by lyophilization for improving the dissolution rate of this poorly water-soluble drug. The effects of main factors influencing the mean particle size (MPS) of vitexin were investigated and optimized...

Compartmental models are the theoretical tool of choice for understanding single neuron computations. However, many models are incomplete, built ad hoc and require tuning for each novel condition rendering them of limited usability. Here, we present T2N, a powerful interface to control NEURON with Matlab and TREES toolbox, which supports generating models stable over a broad range of reconstructed and synthetic morphologies. We illustrate this for a novel, highly-detailed active model of dentate granule cells (GCs) replicating a wide palette of experiments from various labs...

There has been an increase in the use of herbal products to complement conventional drugs in the treatment of various diseases especially in developing countries. This may be attributable to the relatively cost-effectiveness and ease of accessibility of these products as well as the perception of their safety profiles. However, there are numerous literature reports on herbs altering the pharmacokinetics and pharmacodynamics of other co-administered drugs thereby modulating the therapeutic outcomes. The prevalence of diabetes is on a steady increase worldwide and it is now identified as one of the main threats to human health...

BACKGROUND: People with schizophrenia and other severe mental disorders have an increased mortality mainly attributed to natural causes, specifically cardiovascular disease and cancer. The metabolic syndrome and the Framingham Risk Score are epidemiologic tools related to long-term cardiovascular disease risk and they are increased in people with severe mental disorders. This increase has been attributed both to the disorder itself and to the use of antipsychotic drugs. OBJECTIVE: To quantify the cardiovascular risk in a group of people treated with long-acting injectable antipsychotics...

Background Adenosine triphosphate (ATP) is the energy currency of the body; it takes part in various and indispensable metabolic processes for the maintenance of cell homeostasis, degrading to its hydrolysis product, adenosine diphosphate (ADP). Efficient ways to restore ATP are therefore necessary in the cells. When the cell lacks energy due to ischemic conditions or high ATP demand, phosphocreatine gives its phosphate group to ADP that converts to ATP, in a reaction catalyzed by the enzyme creatine kinase...

Tumor necrosis factor-related apoptosis-induced ligand (TRAIL) is nontoxic to normal cells and preferentially cytotoxic to cancer cells. However, recent data suggest that malignant breast cancer cells tend to be resistant to TRAIL. Pterostilbene (PTER), a natural dimethylated analog of resveratrol, is known to have diverse pharmacologic activities, including anticancer properties. In the present study, we investigated whether PTER affects TRAIL-induced apoptosis and its mechanism in TRAIL-resistant triple negative breast cancer (TNBC) cells...

Primary open angle glaucoma (POAG) is the most common type of glaucoma, and is responsible for approximately 90% of glaucoma cases in North America. POAG is characterized by an asymptomatic onset, where patients do not present with symptoms until significant visual loss occurs in late stages of the disease. Importantly, while glaucoma is associated with several risk factors that contribute to damage and disease progression, intraocular pressure (IOP) is the only proven modifiable risk factor at this time. Treatments for POAG include use of pharmacologic and surgical interventions...

Dry mouth (xerostomia), is a fairly common, well-researched condition, which is an indirect cause of oral malodour. This systematic literature review looked into another cause of bad breath: adverse drug reactions in the orofacial region causing halitosis. The study focused on extraoral halitosis, and its subdivisions, particularly blood borne halitosis in which malodourous compounds in the blood stream are carried to the lungs, passively diffused across the pulmonary alveolar membrane to enter the breath. An electronic search was conducted in various databases...
