Abstract

Since the report of retrograde island flap with radial artery by Lu and Wang in 1982 and retrograde island flap with ulnar artery by Li in 1984, the flaps from forearm has been commonly used clinically in recent years because of its good textrue and satisfactory therapeutic results. However, whether the function of hand will be impaired by cutting one of the main arteries which supply the hand still remains controversial. There has been an acute ischemia of hand reported in foreign literature. Since 1985 we have studied 50 upper limbs from fresh cadavers by arteriograghy and vascular dye infusion in our hospital. Based on the results that the distal end of the dorsal interosseous artery of forearm can be anastomosed with a number of dorsal branches of volar interosseous artery at the back of the wrist, we have designed a retrograde island flap with these anastomotic branches as its pedicle to repair soft tissue defect of hands and applied in 71 cases. Seventy flaps survived, only one underwent necrosis because of vascular deformity. It is concluded that the flap has many advantages such as good texture, easiness of anatomical operation and high survival rate. What is more, the flap can be transplanted with nerve, muscle tendon ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
