REVIEW
Sang Jin Kim, Kyung Sik Park
Chronic constipation is one of the most common digestive diseases frequently observed in a clinical setting. It has been known to cause considerable damage to the quality of life of patients. Despite recent developments, there are considerable limitations in the use of constipation-modulating agents in Korea. Chloride channel inhibitors, such as lubiprostone and linaclotide, have not been introduced in Korea yet, and prucalopride and several kinds of polyethylene glycol are not covered under medical insurance...

Microbial transglutaminase (mTG) was used as a crosslinking agent in the preparation of gelatin sponges. The physical properties of the materials were evaluated by measuring their material porosity, water absorption, and elastic modulus. The stability of the sponges were assessed via hydrolysis and enzymolysis. To study the material degradation in vivo, subcutaneous implantations of sponges were performed on rats for 1-3 months, and the implanted sponges were analyzed. To evaluate the cell compatibility of the mTG crosslinked gelatin sponges (mTG sponges), adipose-derived stromal stem cells were cultured and inoculated into the scaffold...

Hypertension has been recognized as one of the highest risk factors for cardiovascular diseases. Anti-hypertension agent screening and development has been recognized as a pharmaceutical therapy approach for the cardiovascular diseases treatment. Many kinds of traditional Chinese medicines, such as pine needle, have been used for the treatment of hypertension for a long time, but the bioactive ingredients which responsible for their therapeutic effectiveness are remain unclear. Therefore, screening bioactive chemicals in natural sources is still the most straightforward strategy for novel Angiotensin-converting enzyme inhibitor (ACEi)-based anti-hypertension agents discovery...

Methylation of lysine-4 of histone H3 (H3K4men) is an important regulatory factor in eukaryotic transcription. Removal of the transcriptionally activating H3K4 methylation is catalysed by histone demethylases, including the JmjC KDM5 subfamily. The JmjC KDMs are Fe(II) and 2-oxoglutarate (2OG) dependent oxygenases, some of which are associated with cancer. Altered levels of TCA cycle intermediates, and the associated metabolites D- and L-2-hydroxyglutarate (2HG), can cause changes in chromatin methylation status...

The ability to control drug release at a specific physiological target enables the possibility of an enhanced therapeutic effect with reduced off-target toxic side effects. The discipline of controlled drug release has grown to include most areas of medicine with examples in the literature of targeted drug delivery to the majority of organs within the human body. In addition, a variety of external stimuli used to meditate the drug release process have also been investigated. Nonetheless, the concurrent real time monitoring of drug release has not been widely studied...

Ayurvedic drugs are anecdotally considered safe and are sparingly reported for adversity upon their usage. Reporting adversity however helps understanding the drug pharmacodynamics in a given case and prompts for its safe future application. The patient here has reported urticarial rashes upon use of an Ayurvedic guggulu preparation. The observations were repeated upon the repeated use of the drug. These symptoms were compelling enough to look for a rescue medicine and to withdraw the primary medicine. Guggulu is known for its gastrointestinal and hepatic adversities in some cases...

Since the advent of the HER2 biomarker allowing access to treatment with trastuzumab, we observe an explosion in research for biomarkers, in which the economic pressure linked to the costs of developing new products must not be overlooked, in order to better select the molecules to be developed and the patients who can benefit from them. Personalized medicine takes a little more space each year in the overall care of our patients and the search for specific indicators, has become unavoidable. Rapid identification of oncogenic changes, their therapeutic targeting and the anticipation of resistance or toxicity mechanisms is a challenge...
