Celecoxib (CXB) is a poorly aqueous solubility sulfonamide non-steroidal anti-inflammatory drug (NSAID). Hence, the formulation of CXB was selected for solubilization and bioavailability. To find out suitable formulation for microemulsion, the solubility of CXB in triacetin (oil phase), Tween 80 (surfactant), and Transcutol-P (co-surfactant) was screened respectively and optimized by using orthogonal experimental design. The Km value and concentration of oil, Smix, and water were confirmed by pseudo-ternary phase diagram studies and central composite design...

: Non-steroidal anti-inflammatory drug (NSAID)-associated endoplasmic reticulum (ER) stress (a cyclooxygenase-2-independent mechanism) and consequent autophagic cell death are responsible for NSAID-associated gastric damage. Therefore, alleviating cytotoxicity executed via ER stress and autophagy can be a strategy to prevent NSAID-associated gastric damage. Here, we explored whether genetic or pharmacologic inhibition of autophagy can mitigate NSAID-associated gastric damage in in vitro and in vivo models...

: Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most widely used medicine to treat pain, fever, inflammation and to inhibit platelet function. Understanding the expression regulation of enzymes of the prostanoid pathway is of great medical relevance. Histone acetylation crucially controls gene expression. We set out to identify the impact of histone deacetylases (HDACs) on the generation of prostanoids and examine the consequences on vascular function. Inhibition of HDACs (HDACi) with the pan HDAC inhibitor SAHA attenuated prostaglandin E2 (PGE2) generation in the murine vasculature and in human vascular smooth muscle cells...

Inflammation is associated with the development and malignant progression of most cancers. As most of the cell types involved in cancer-associated inflammation are genetically stable and thus are not subjected to rapid emergence of drug resistance, the targeting of inflammation represents an attractive strategy both for cancer prevention and for cancer therapy. Tumor-extrinsic inflammation is caused by many factors, including bacterial and viral infections, autoimmune diseases, obesity, tobacco smoking, asbestos exposure, and excessive alcohol consumption, all of which increase cancer risk and stimulate malignant progression...

We are just beginning to understand the allosteric regulation of the human cytosolic sulfotransferase (SULTs) family-13 disease-relevant enzymes that regulate the activities of hundreds, if not thousands, of signaling small molecules. SULT1A1, the predominant isoform in adult liver, harbors two noninteracting allosteric sites, each of which binds a different molecular family: the catechins (naturally occurring flavonols) and nonsteroidal antiinflammatory drugs (NSAIDs). Here, we present the structure of an SULT allosteric binding site-the catechin-binding site of SULT1A1 bound to epigallocatechin gallate (EGCG)...

: Approximately a quarter of the world's population at some point in life is at risk of developing shingles (Herpes Zoster). In 10-20% of cases the first branch of the trigeminal nerve gets involved (Herpes Zoster Ophthalmicus, HZO). Ophthalmic complications of HZO are able to cause a significant reduction in visual function. AIM: To study and summarize clinical features of HZO (including the rate of complications and their nature) and to determine the relationship between clinical and laboratory data from these patients...

Cancer cells require nourishment for the growth of the primary tumor mass and spread of the metastatic colony. These needs are fulfilled by tumor-associated neovasculature known as angiogenesis, which also favors the transition from hyperplasia to neoplasia, that is, from a state of cellular multiplication to uncontrolled proliferation. Therefore, targeting angiogenesis is profitable as a mechanism to inhibit tumor growth. Furthermore, it is important to understand the cross-communication between vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) in the neoplastic and proinflammatory milieu...

Microparticles are polymeric bodies ranging 1-1000 µm that constitute a variety of forms such as microcapsules, microspheres, microcages, microshells, microrods, biosensors microparticles, radiolabeled microparticles, and so forth. This review focuses on general microparticles, mainly microcapsules and microspheres. Nonsteriodal anti-inflammatory drugs (NSAIDs) are one of the mostcommonly prescribed medications in the world. Most of the NSAIDs available have severe side effects. With increased awareness of NSAID-induced gastrointestinal (GI) side effects, safety has become a priority in treatment of arthritis and other inflammatory diseases with NSAIDs...

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery is a safe and effective procedure for patients with severe obesity. One potential complication of LRYGB is the development of marginal ulcers (MUs). Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to significantly increase the likelihood of developing marginal ulcers after surgery. However, the risk associated with low-dose aspirin consumption is not well defined. We examined the impact of daily low-dose aspirin (81 mg) on the development of marginal ulcers following LRYGB...

Fracture healing is a complex regeneration process which produces new bone tissue without scar formation. However, fracture healing disorders occur in approximately 10% of human patients and cause severe pain and reduced quality of life. Recently, the development of more standardized, sophisticated and commercially available osteosynthesis techniques reflecting clinical approaches has increased the use of small rodents such as rats and mice in bone healing research dramatically. Nevertheless, there is no standard for pain assessment, especially in these species, and consequently limited information regarding the welfare aspects of osteotomy models...

The most common small bowel inflammatory disorders include Crohn disease, nonsteroidal antiinflammatory drug (NSAID) enteropathy, and celiac disease. Capsule endoscopy, computed tomography enterography, and magnetic resonance enterography have a complementary role in the diagnosis of Crohn disease and evaluation of patients with established Crohn disease. The higher risk of capsule retention with known Crohn disease and NSAID enteropathy can be minimized by cross-sectional imaging or the patency capsule. The main role of deep enteroscopy is tissue diagnosis, endoscopic management of small bowel lesions and strictures, and retrieval of retained capsules...

Bertolotti's syndrome (BS) must be considered as a differential diagnosis in a young patient presenting with low back pain (LBP). We present a case of a 26-year-old male complaining of mild chronic LBP for six years, radiating to his left thigh for the past six months. He has been taking non-steroidal anti-inflammatory drugs (NSAIDs) with skeletal muscle relaxants for pain relief. The X-ray and computed tomography (CT) imagings showed congenital enlargement of the left transverse process of the fifth lumbar (L5) vertebra forming pseudo-articulation with the sacrum and unilateral pars interarticularis defect at the L4 level on the left side, respectively...

The consumption of low-dose aspirin (LDA) to prevent cardiovascular disease continues to increase worldwide. Consequently, the number of chronic LDA users seeking dental procedures that require complementary acute anti-inflammatory medication has also grown. Considering the lack of literature evaluating this interaction, we analyzed the gastric and renal effects caused by a selective COX-2 inhibitor (etoricoxib) and a non-selective COX-2 inhibitor (ibuprofen) nonsteroidal anti-inflammatory drug (NSAID) in rats receiving chronic LDA therapy...
