Robot-assisted retroperitoneal laparoscopic excision of perirenal vascular tumor: A case report.

Background: A vascular tumor is a benign tumor with unique clinical and pathological features. Perirenal vascular tumor is extremely rare and has not yet been reported. Clinically, it manifests as soreness and swelling.

Electrophysiological Characteristics in Depressive Personality Disorder: An Event-Related Potential Study.

This study aimed to investigate the neurophysiological characteristics of young people with depressive personality disorder using event-related potentials (ERP). To explore the effects of visual-emotional words on ERP, mainly N350, we recruited 19 individuals with a depressive personality disorder and 10 healthy controls. ERP were recorded while the subjects took decisions on target words that were classified into three categories: emotionally positive, negative, and neutral.

Oxidative stress and substance P mediate psychological stress-induced autophagy and delay of hair growth in mice.

Neuropeptide substance P (SP) and reactive oxygen species (ROS) have been demonstrated to play an important role in psychological stress-induced alteration of hair cycle, the underlying mechanism remains unknown. The present study aims to investigate possible contribution of SP and ROS in chronic restraint stress (CRS, a chronic psychological stress model) induced abnormal of hair cycle and induction of autophagy. Mouse CRS model was applied for 18 days with or without treatment antioxidant Tempol (a free radical scavenger) or SP receptor (NK1) antagonist (RP67580).

Y chromosomes of 40% Chinese descend from three Neolithic super-grandfathers.

Demographic change of human populations is one of the central questions for delving into the past of human beings. To identify major population expansions related to male lineages, we sequenced 78 East Asian Y chromosomes at 3.9 Mbp of the non-recombining region, discovered >4,000 new SNPs, and identified many new clades.

Chronic restraint stress inhibits hair growth via substance P mediated by reactive oxygen species in mice.

Backgrounds: Solid evidence has demonstrated that psychoemotional stress induced alteration of hair cycle through neuropeptide substance P (SP) mediated immune response, the role of reactive oxygen species (ROS) in brain-skin-axis regulation system remains unknown.

Objectives: The present study aims to investigate possible mechanisms of ROS in regulation of SP-mast cell signal pathway in chronic restraint stress (CRS, a model of chronic psychoemotional stress) which induced abnormal of hair cycle.

Methods And Results: Our results have demonstrated that CRS actually altered hair cycle by inhibiting hair follicle growth in vivo, prolonging the telogen stage and delaying subsequent anagen and catagen stage.
