Abstract

Retroperitoneal laparoscopic radical and partial nephrectomy (RLRN and RLPN) have become the preferred modes of management for renal malignancy. One of the most critical steps in the RLRN and RLPN process is to seek and control the renal pedicle. The current study focuses on introducing methods and techniques that can help quickly and accurately identify the renal pedicle vessels during RLRN and RLPN. RLRNs and RLPNs were performed for 292 cases in our hospital from November 2014 to January 2017. Different measures were adopted to seek and manage bilateral renal pedicle vessels. All operation procedures were performed by the following three steps: dissection, opening, and clamping. For the left lateral, after the perirenal fat in the dorsal and lateral side was fully dissected, the kidney was pushed toward the ventral side. The renal artery was visible when opening the dense bulging connective tissue, which was located in the middle of the dorsal interior of the kidney. Then, the renal artery was clamped with a Hem-o-lok or the Bulldog clamp. For the right kidney pedicles, the inferior vena cava was first identified and then dissipated upward. When the inferior vena cava was not visible, it was often the location of the right r...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.
