To evaluate the tissue damage of in vitro porcine ovarian drilling in saline solution mimicking transvaginal hydrolaparoscopy (THL). In vitro ovarian drilling with different current and activation time was applied on fresh porcine ovaries, 15 ovaries in each group and 2 punctures in each ovary. Drilling using 5-Fr bipolar needle was performed in saline solution mimicking THL, while saline solution rinsing the ovaries after monopolar electrocoagulation. The monopolar drilling caused more tissue damage than the bipolar needle in saline (p < 0.01). The ratio of the damage of monopolar electrocoagulation (40 w, 3s) over that of bipolar diathermy in saline solution (70 w, 15 s) was 7.4 [(16.74 +/- 1.30) mm(3)/(2.27 +/- 0.49) mm(3)]. In the bipolar groups, the 70 w power set (15s and 20 s) caused significantly more tissue damage than the 50 w ones (p < 0.05), and the amount of damage was not stimulation time dependent (p > 0.05). The tissue damage caused by monopolar electrocoagulation with 40 w for 3 s was about seven times of that caused by 5-Fr bipolar one in saline with 70 w for 15 s . In THL drilling using a 5-Fr bipolar electrode, the current is more crucial than stimulation time.

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.

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.

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.
