In order to treat Coronavirus Disease 2019 (COVID-19), we predicted and implemented a drug delivery system (DDS) that can provide stable drug delivery through a computational approach including a clustering algorithm and the Schrödinger software. Six carrier candidates were derived by the proposed method that could find molecules meeting the predefined conditions using the molecular structure and its functional group positional information. Then, just one compound named glycyrrhizin was selected as a candidate for drug delivery through the Schrödinger software.

Insulin resistance is the critical condition for the development of metabolic syndromes including type II diabetes and heart disease. To investigate the active components of root which is known to increase insulin sensitivity, its methanol extract was subfractionated. The ethyl acetate (EtOAc) fraction of the root extract significantly promoted adipocyte differentiation in 3T3-L1 preadipocyte cells.

Femoral fractures due to birth trauma are an extremely rare but important birth injury. While vaginal breech delivery, although rare, can cause femur fracture, abdominal breech delivery is not expected to cause fracture. Here we report on a low birth weight infant who was delivered by cesarean section for breech presentation at 30 1/7 weeks of gestation and sustained a unilateral fracture of the femoral shaft.

Bartholin's duct cysts, the most common growths in the vulva, occur in the labia majora. The cyst may become infected, and an abscess may develop in the gland. Rectovaginal fistula is a rare complication and its formation is secondary to Bartholin's cyst; only 4 cases have been reported in the literature so far.

Symptoms of a peritoneal progression from ovarian cancer are nonspecific such as abdominal pain, abdominal distention and more. Many imaging studies and serum CA-125 help diagnosis. However, it is difficult to exclude the instances of the diffuse peritoneal diseases that mimic carcinomatosis.

Fruits of the Litsea family of trees and shrubs contain biologically active compounds, some of which have been used as natural nutrients and flavoring agents in food. In this study, we identified novel anti-nociceptive effects of the 30% ethanol extract, the CH(2)Cl(2) fraction and the associated active components (Hamabiwalactone A and B) from Litsea japonica fruit by using in vivo peripheral and central nervous pain models. In addition, we compared the anti-inflammatory effects of several fractions from L.

The tuber of Liriope platyphylla Wang et Tang (Liliaceae), also known as Liriopis tuber, is famous in Oriental medicine owing to its tonic, antitussive, expectorant and anti-asthmatic properties. In the present study, the effects of Liriopis tuber water extract (LP) on proinflammatory mediators secreted from lipopolysaccharide (LPS)-induced cultured RAW 264.7 mouse macrophages were investigated.
