Thromboangiitis obliterans (TAO) is a chronic, non-atherosclerotic, progressive inflammatory vascular disease affecting the small- and medium-size arteries and veins of the extremities.
To evaluate whether long-term anticoagulation with low-molecular-weight heparin (LMWH) and warfarin is beneficial for treating the inflammation and symptoms associated with TAO.
Patients with TAO who underwent anticoagulation as the mainstay of treatment were included in this prospective study. Rest pain relief and healing of trophic lesions (as the primary and secondary endpoint) were investigated at Day 14 and after 6 months of follow-up. High sensitivity C-reactive protein (hsCRP), monocyte count, and ankle-brachial index (ABI) were recorded, and the difference was compared before and after 2-week anticoagulation. The Chi-square test was used to compare the difference between anticoagulant and aspirin groups (based on the literature).
From 2014 to 2019, 18 patients were included. Only 1 patient with wet gangrene received endo-therapy for a failing stent at the start of treatment. After ~14 days, 12 of 13 (92%) patients showed complete ulcer healing, and 17 of 18 (94%) patients showed complete relief from rest pain. Monocyte-counts and hsCRP levels decreased significantly (p<0.001) after a 2-week period of anticoagulation with LMWH. The mean follow-up was 2.6 years (range 0.5-5 years). At 6 months, all patients showed relief of rest pain and complete healing of trophic lesions. All endpoints were significantly improved compared with the aspirin group (p<0.01), and no rest pain or ulcer/gangrene recurred during follow-up.
Anticoagulant therapy may alleviate the inflammation and symptoms of TAO.

Recombinant adeno-associated virus (rAAV) has been widely used as an efficient transgenic vector in biomedical research, as well as gene therapy. Serotype-associated transduction efficiency, tissue- or cell-type tropism and immunological profile are major considerations in the various applications of rAAVs. Linifanib supplier There are increasing needs for different serotypes of rAAV, either naturally isolated or artificially engineered. However, affordable and scalable production of a desired serotype of rAAV remains very difficult, especially for researchers lacking relevant experience.
On the basis of our previously established single recombinant baculovirus expression vector (BEV)-derived OneBac system, we have optimized the process and expanded the rAAV production range to the full range of serotypes rAAV1-13.
Firstly, the AAV Cap gene was optimized to translate by ribosome leaky scanning and the gene of interest (GOI) was cloned into the pFD/Cap-(ITR-GOI)-Rep2 shuttle plasmid. Following the classical Bac-to-Bac method, sufficient BEV stock containing all rAAV packaging elements can be quickly obtained. Finally, we can repeatedly scale up the production of rAAVs in one week by using a single BEV to infect suspension-cultured Sf9 cells. The rAAV1-13 shows relatively high yields ranging from 5×10
to 4×10
VG/cell. More than 1×10
VG purified rAAVs can be easily obtained from 5 L suspension-cultured Sf9 cells.
As expected, rAAV serotypes 1-13 show different potencies for in vitro transduction and cell-type tropisms.
In summary, the single BEV-derived OneBac system should prove popular for laboratory scaling-up production of any serotype of rAAV.

Compared to the traditional drug formulations, Nano-DDS can increase solubility, biocompatibility, and reduce off-targeted side effects of free drugs. However, they still have some disadvantages that pose a limitation in reaching their full potential in clinical use. Protein adsorption in blood, activation of the complement system, and subsequent sequestration by the mononuclear phagocyte system (MPS) consequently result in nanoparticles (NPs) to be rapidly cleared from circulation. Therefore, NPs have low drug delivery efficiency. So, it is important to develop stealth NPs for reducing bio-nano interaction. In this review, we first conclude the interaction between NPs and biological environments, such as blood proteins and MPS, and factors influencing each other. Next, we will summarize the new strategies to reduce NPs protein adsorption and uptake by the MPS based on current knowledge of the bio-nano interaction. Further directions will also be highlighted for the development of biomimetic stealth nano-delivery systems by combining targeted strategies for a better therapeutic effect.
Psoriasis is a challenging skin disorder due to its chronicity, high rate of prevalence, disability, comorbidity and disfiguration. It is a multi-system disorder that includes joints and metabolic syndromes. Psoriasis is a condition of pathologic interaction among immune cells, biological signaling molecules and skin cells. Several contributing factors are responsible for the exacerbation and onset of psoriasis, i.e. genetic factors and environmental factors such as medications, infectious diseases and lifestyle.
To study the new insights in the treatment of psoriasis and future prospects.
This review article gives an insight on the current concepts of psoriasis and deals with discussing the initiation and development of the diseases. We described the pathogenetic pathway for psoriasis. The article focuses on the treatment approaches for psoriasis that have arisen from the dissection of the inflammatory psoriatic pathways.
We aimed to highlight the novel therapies and drugs used in the treatment of psoriasis, including food and drug administration (FDA) approved drugs and drugs under clinical trials. The treatment can be initiated for mild to the moderate diseased condition employing vitamin D3 analogues, corticosteroids and a combination of products as first-line therapy.
Psoriasis can be managed by a proper understanding of the immune function. We have also discussed medicinal herbs used for psoriasis based on their ethnopharmacological knowledge and reported work of researchers.
