One aspect of the study of the origins of life focuses on how primitive chemistries assembled into the first cells on Earth and how these primitive cells evolved into modern cells. Membraneless droplets generated from liquid-liquid phase separation (LLPS) are one potential primitive cell-like compartment; current research in origins of life includes study of the structure, function, and evolution of such systems. However, the goal of primitive LLPS research is not simply curiosity or striving to understand one of life's biggest unanswered questions, but also the possibility to discover functions or structures useful for application in the modern day. Many applicational fields, including biotechnology, synthetic biology, and engineering, utilize similar phaseseparated structures to accomplish specific functions afforded by LLPS. Here, we briefly review LLPS applied to primitive compartment research and then present some examples of LLPS applied to biomolecule purification, drug delivery, artificial cell construction, waste and pollution management, and flavor encapsulation. Due to a significant focus on similar functions and structures, there appears to be much for origins of life researchers to learn from those working on LLPS in applicational fields, and vice versa, and we hope that such researchers can start meaningful cross-disciplinary collaborations in the future.The discovery of human pluripotent stem cells (PSCs) at the turn of the century opened the door to a new generation of regenerative medicine research. Among PSCs, the donors available for induced pluripotent stem cells (iPSCs) are greatest, providing a potentially universal cell source for all types of cell therapies including cancer immunotherapies using natural killer (NK cells). Unlike primary NK cells, those prepared from iPSCs can be prepared with a homogeneous quality and are easily modified to exert a desired response to tumor cells. There already exist several protocols to genetically modify and differentiate iPSCs into NK cells, and each has its own advantages with regards to immunotherapies. In this short review, we detail the benefits of using iPSCs in NK cell immunotherapies and discuss the challenges that must be overcome before this approach becomes mainstream in the clinic.

Postprocedural bleeding is known to be relatively low after argon plasma coagulation (APC) for gastric neoplasms; however, there are few studies proving the effect of antithrombotic agents. This study aimed to analyze the incidence of delayed bleeding (DB) based on antithrombotic agents administered and to identify the risk factors for DB in APC for gastric tumors.

A total of 785 patients with 824 lesions underwent APC for single gastric neoplasm between January 2011 and January 2018. After exclusion, 719 and 102 lesions were classified as belonging to the non-antithrombotics (non-AT) and AT groups, respectively. The clinical outcomes were compared between the two groups, and we determined the risk factors for DB in gastric APC.

Of the total 821 cases, DB occurred in 20 cases (2.4%) 17 cases in the non-AT group and three cases in the AT group (2.4% vs 2.9%, p=0.728). Multivariate analysis of the risk factors for DB confirmed the following significant, independent risk factors male sex (odds ratio, 7.66; 95% confidence interval, 1.02 to 57.69; p=0.048) and chronic kidney disease (odds ratio, 4.51; 95% confidence interval, 1.57 to 13.02; p=0.005). Thromboembolic events and perforation were not observed in all patients regardless of whether they took AT agents.

AT therapy is acceptably safe in gastric APC because it does not significantly increase the incidence of DB. However, patients with chronic kidney disease or male sex need to receive careful follow-up on the incidence of post-APC bleeding.

Improving quality of life has been gaining importance in ulcerative colitis (UC) management. The aim of this study was to investigate changes in health-related quality of life (HRQL) and related factors in patients with moderate-to-severe UC.

A multicenter, hospital-based, prospective study was performed using a Moderateto- Severe Ulcerative Colitis Cohort in Korea (the MOSAIK). Changes in HRQL, evaluated using the 12-Item Short Form Health Survey (SF-12) and Inflammatory Bowel Disease Questionnaire (IBDQ), were analyzed at the time of diagnosis and 1 year later.

In a sample of 276 patients, the mean age was 38.4 years, and the majority of patients were male (59.8%). HRQL tended to increase in both the IBDQ and SF-12 1 year after diagnosis. A higher partial Mayo score was significantly related to poorer HRQL on the IBDQ and SF-12 in a linear mixed model (p<0.01). Inflammatory markers such as C-reactive protein (CRP) or erythrocyte sedimentation rate also showed a negative correlation on HRQL (p<0.05). Patients whose IBDQ score improved by 16 or more (71.2%) in 1 year were younger, tended to be nonsmokers, and had a lower partial Mayo score and CRP than those whose IBDQ score did not. There was no significant association between HRQL and disease extent, treatments at diagnosis, or the highest treatment step during the 1-year period.

Optimally controlled disease status improves HRQL in patients with moderate-tosevere UC. The partial Mayo score and inflammatory markers may be potential indicators reflecting the influence of UC on patient`s daily lives.

After esophagogastroduodenoscopy (EGD) with biopsy, some patients experience gastrointestinal symptoms. This study investigated the effect of sodium alginate on biopsy-related gastrointestinal symptoms.

In this open-label, randomized, controlled trial, patients undergoing EGD with biopsy were randomly assigned to a treatment or control group. In the treatment group, sodium alginate was orally administered for 3 days after EGD. Patients completed questionnaires about their gastrointestinal symptoms at baseline (past week), the day after returning home, and after another 3 days. Gastrointestinal symptoms, including abdominal pain, epigastric pain/soreness, heartburn, acid reflux, nausea/vomiting, borborygmus, abdominal distension, and belching, were rated using an upper gastrointestinal symptom rating scale (GSRS).

A total of 210 persons (138 men) who underwent EGD with biopsy were enrolled and allocated to the treatment (n=104) or control (n=106) group. At baseline, the demographic factors and GSRS scores were not different between the control and treatment groups. The epigastric pain/soreness score increased in the control group after endoscopic biopsy (+0.056), whereas the score was decreased in the treatment group (-0.067) (p=0.042). In the treatment group, the scores for acid regurgitation and epigastric soreness decreased during follow-up from those at baseline (p<0.05), whereas there were no significant reductions in the control group. The scores for belching and borborygmus decreased during follow-up only in the treatment group. Abdominal bloating decreased in both the control and treatment groups.

Sodium alginate reduced epigastric pain/soreness after EGD with biopsy. Therefore, the prescription of sodium alginate should be considered after endoscopic biopsy.

During initial part of his academic career, he adopted human dissection based experiments as medium of his research. This was in accordance with prevailing trend among anatomists during 17th century. He discovered the presence of tiny venous tributaries communicating between cardiac veins and chambers of heart (ducti carnosi/venae cordis minimae). He reported the existence of a collateral circulatory pathway between right and left coronary arterial systems (Vieussens arterial ring). He was the first to note the valve at the junction of great cardiac vein and coronary sinus (valve of Vieussens) and the prominent oval margin of the fossa ovalis (Vieussens Annulus). All his findings were associated with considerable clinical significance as evidenced in literature that followed. Vieussens accurately demonstrated the three-layered orientation of myocardium and gave a precise description of coronary arteries and their branches. At the onset of 18th century, buoyed by royal patronage from King Louis XIV of France, the second half of Vieussens illustrious career was defined by pathologic anatomy (autopsy based) and anatomo clinical correlations. This was a new trend initiated by Vieussens in anatomical research and was later adopted as a signature method by anatomists of 18th century. As a true connoisseur of cardiologic anatomy, Vieussens accurately charted the anatomo clinical correlations of cardiac tamponade, mitral stenosis and aortic regurgitation. His contributions were pivotal elements in metamorphosis of cardiology as a robust discipline of medicine in modern times.The aim of this study is to investigate the volumetric measurements of the maxillary sinus among Indonesian population through computed tomography (CT) scan semi-automated segmentation. find protocol This project collected 802 retrospective head CT scan archives from Department of Radiology, Hasan Sadikin Hospital, Bandung, Indonesia between 2019-2020. Patients with craniofacial anomalies/pathology fracture in proximity of the maxillary sinuses, and mediocre image quality were excluded from this study resulting only 97 CT scan archives (194 maxillary sinuses; 52 males; 45 females; age range 0-25 years old). Three-dimensional craniofacial structures were reconstructed and volumetric measurements of the maxillary sinus were computed through semi-automated segmentation using ITK-SNAP. This study recorded the initial phase of maxillary sinus pneumatization during infancy. The maxillary sinus developed until reaching the maximum of average maxillary sinus volume at 13,278.73 mm3 in 16 to 20 years old group in which afterwards fell to 12,325.21 mm3. There was no difference found between right and left maxillary sinus volume. This study revealed that the pneumatization of maxillary sinus begin during infancy and climb until reaching the second decade of life, in which after that slowly decrease. Moreover, no difference between right and left maxillary sinus volume was detected. The volumetric dimension of maxillary sinus presented in this study may serve as the basis knowledge surgical intervention of maxillary sinus and its related structures.The pharmaceutical industry and clinical trials have been revolutionized mesenchymal stem cell-based therapeutics. However, little has the pharmacokinetics of transplanted cells been characterized in their target tissues under healthy or disease condition. A qPCR analytical method with matrix effect was developed to track the biodistribution of human mesenchymal stem cells in normal and Con A induced liver injury mice. MSC disposition in blood and different organs were compared and relevant PK parameters were calculated. Human and mice MSCs (hMSCs and mMSCs) displayed a very similar pharmacokinetic profile in all tested doses about 95% of the detected hMSCs accumulated in the lung, 3% in the liver, while almost negligible cells were detected in other tissues. A significant double peak of hMSCs concentration emerged in the lung within 1-2 hours after intravenous injection, so did the mMSCs. Prazosin, a vasodilator could eliminate the second peak in the lung and increase its Cmax and AUC by 10% in the first 2 hours.
