The role of fibronectin in multiple sclerosis and the effect of drug delivery across the blood-brain barrier.

Remyelination failure is one of the main characteristics of multiple sclerosis and is potentially correlated with disease progression. Previous research has shown that the extracellular matrix is associated with remyelination failure because remodeling of the matrix often fails in both chronic and progressive multiple sclerosis. Fibronectin aggregates are assembled and persistently exist in chronic multiple sclerosis, thus inhibiting remyelination.

Integrated strategy of LC-MS and network pharmacology for predicting active constituents and pharmacological mechanisms of Ranunculus japonicus Thunb. for treating rheumatoid arthritis.

Ethnopharmacological Relevance: Ranunculus japonicus Thunb. (short for R. japonicus) is a topically applied herb with the activities of removing jaundice, nebula and edema, preventing malaria, stopping asthma, promoting diuresis and relieving pain.

Transcriptomic analysis of flower induction for long-day pitaya by supplementary lighting in short-day winter season.

Background: Pitayas are currently attracting considerable interest as a tropical fruit with numerous health benefits. However, as a long-day plant, pitaya plants cannot flower in the winter season from November to April in Hainan, China. To harvest pitayas with high economic value in the winter season, it is necessary to provide supplementary lighting at night to induce flowering.

Type II caesarean scar pregnancy management by ultrasound-guided local lauromacrogol injection in combination with suction curettage: A case report.

Introduction: The implantation of a gestational sac within the scar of a previous caesarean delivery is defined as caesarean scar pregnancy (CSP), which is classified into two types: CSP I and CSP II. CSP II is life threatening, and no clear consensus for CSP II management exists.

Patient Concerns: A 31-year-old woman, gravida 1, para 1, with a previous caesarean delivery due to macrosomia, presented with an estimated 45 days of amenorrhea.

Molecular characterization and expression analysis of pitaya (Hylocereus polyrhizus) HpLRR genes in response to Neoscytalidium dimidiatum infection.

Background: Canker disease caused by Neoscytalidium dimidiatum is a devastating disease resulting in a major loss to the pitaya industry. However, resistance proteins in plants play crucial roles to against pathogen infection. Among resistance proteins, the leucine-rich repeat (LRR) protein is a major family that plays crucial roles in plant growth, development, and biotic and abiotic stress responses, especially in disease defense.

Transcriptomic de novo analysis of pitaya (Hylocereus polyrhizus) canker disease caused by Neoscytalidium dimidiatum.

Background: Canker disease caused by Neoscytalidium dimidiatum is the most serious disease that attacks the pitaya industry. One pathogenic fungus, referred to as ND8, was isolated from the wild-type red-fleshed pitaya (Hylocereus polyrhizus) of Hainan Province. In the early stages of this disease, stems show little spots and a loss of green color.

Effects of dipeptidyl peptidase-4 inhibitors on transforming growth factor-β1 signal transduction pathways in the ovarian fibrosis of polycystic ovary syndrome rats.

Aim: Examine the effects of dipeptidyl peptidase-4 (DPP4) inhibitor Sitagliptin on the transforming growth factor-β1 (TGF-β1) signal transduction pathway in polycystic ovary syndrome (PCOS) rats with ovarian fibrosis.

Methods: Thirty rats were divided randomly into the PCOS model group, Sitagliptin treatment group and blank control group. Dehydroepiandrosterone was administered to the model group and treatment group to establish the models.

Purification and characterization of albumin from frog skin of Duttaphrynus melanostictus.

Following determination of trypsin inhibitory activity, a serine protease inhibitor was purified and characterized from frog Duttaphrynus melanostictus serum. It was identified as serum albumin, with molecular weight of 67 kDa (DmA-serum). Different from bovine serum albumin, DmA-serum potently inhibited trypsin with similar K(i) values around 1.

Purification and characterization of an irreversible serine protease inhibitor from skin secretions of Bufo andrewsi.

Amphibian skin secretions contain many bioactive compounds. In the present work, an irreversible serine protease inhibitor, termed baserpin, was purified for the first time from the skin secretions of toad Bufo andrewsi by successive ion-exchange and gel-filtration chromatography. Baserpin is a single chain glycoprotein, with an apparent molecular weight of about 60 kDa in SDS-PAGE.

Bm-TFF2, a trefoil factor protein with platelet activation activity from frog Bombina maxima skin secretions.

In mammals, trefoil factor family (TFF) proteins are involved in mucosal maintenance and repair, and they are also implicated in tumor suppression and cancer progression. A novel two domain TFF protein from frog Bombina maxima skin secretions (Bm-TFF2) has been purified and cloned. It activated human platelets in a dose-dependent manner and activation of integrin alpha(IIb)beta(3) was involved.
