Abstract

To study the epidemiological features of syndactyly (SD) in Chinese perinatals. Data were collected through Chinese Birth Defects Monitoring Network, a hospital-based congenital malformation registry system. From 1987 through 2001 (except 1994, 1995), all live or still births with 28 weeks of gestation or more born in participating hospitals were assessed within 7 days after delivery. Totally 2311 perinatals with SD were identified among 7 478 746 births, and 57.2% of them were in association with other anomalies. The overall prevalence rate of SD was 3.09/10 000, the rate of isolated SD and associated SD was 1.32/10 000, and 1.77/10 000 respectively. The prevalence rates in urban and rural areas, in male and female births were 3.22/10 000 and 2.79/10 000, 3.42/10 000 and 2.59/10 000 respectively. An increasing trend was found during that period. The perinatal fatality rate of SD was 20.7%, that of isolated form was 5.7%, while that of associated form was 31.9%. The proportion of SD occurring in right side was the same as that in left side, and the proportion of SD in upper limbs equaled to that in lower limbs. The prevalence rate of SD in Chinese perinatals was similar to that reported in foreign literatures. Associated form o...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.
