This review explains the current status of the theory for microbiologists; its roots, predictions, experimental evidence and future directions.Progesterone receptor (PGR) is indispensable for pregnancy in mammals. Uterine PGR responds to the heightened levels of ovarian progesterone (P4) after ovulation and regulates uterine gene transcription for successful embryo implantation. Although epithelial and stromal P4-PGR signaling may interact with each other to form appropriate endometrial milieu for uterine receptivity and the subsequent embryo attachment, it remains unclear what the specific roles of epithelial P4-PGR signaling in the adult uterus are. Here we generated mice with epithelial deletion of Pgr in the adult uterus (Pgrfl/flLtfCre/+ mice) by crossing Pgr-floxed and Ltf-Cre mice. Selleck DMX-5084 Pgrfl/flLtfCre/+ mice are infertile due to the impairment of embryo attachment. Pgrfl/flLtfCre/+ uteri did not exhibit epithelial growth arrest, suggesting compromised uterine receptivity. Both epithelial and stromal expressions of P4-responsive genes decreased in Pgrfl/flLtfCre/+ mice during the peri-implantation period, indicating that epithelial Pgr deletion affects not only epithelial but stromal P4 responsiveness. In addition, uterine LIF, an inducer of embryo attachment, was decreased in Pgrfl/flLtfCre/+ mice. The RNA-seq analysis using luminal epithelial specimens dissected out by laser capture microdissection revealed that the signaling pathways related to extracellular matrix, cell adhesion, and cell proliferation are altered in Pgr fl/flLtf Cre/+ mice. These findings suggest that epithelial PGR controls both epithelial and stromal P4 responsiveness and epithelial cell differentiation, which provides normal uterine receptivity and subsequent embryo attachment.
Advanced-stage (Child-Pugh classes B and C) liver cirrhosis (LC) is a contraindication for oesophagectomy. However, the question as to whether Child-Pugh class A LC may have an impact on perioperative outcomes remains unanswered. This retrospective single-centre study was designed to address this issue.

This was a single-centre, retrospective, propensity-matched study. The perioperative outcomes of patients with Child-Pugh class A LC were compared with those of patients without LC after propensity score matching.

Out of a cohort consisting of 811 patients, we identified 51 cases with Child-Pugh class A LC. After the application of propensity score matching, the LC and no-LC groups consisted of 50 and 100 patients, respectively. The presence of LC did not compromise the quality of surgical resection as attested to by similar lymph node yields and R0 rates. However, patients with LC patients were more prone to developing postoperative pneumonia (22% vs 9%, P = 0.027), pleural effusion (38% vs 20%, P = 0.018) and chylothorax (10% vs 1%, P = 0.016) and had longer intensive care unit stay (mean 6.10 vs 2.58 days, P = 0.002) compared with the no-LC group. Multivariable analysis identified thoracic duct ligation [odds ratio (OR) 12.292, P = 0.042] and a higher number of dissected nodes (OR 4.375, P = 0.037) as independent risk factors for chylothorax and pleural effusion, respectively. The detrimental effect of these variables was limited to the LC group.

Oesophagectomy portends a higher morbidity in patients with Child-Pugh class A LC. A meticulous management of lymphatic ducts during mediastinal dissection may improve surgical outcomes in this high-risk group.

DNA from many pathogens can be detected in saliva. However, the presence and quantity of Treponema pallidum DNA in syphilis patients in saliva is unknown.

A total of 234 syphilis patients with different stages and 30 volunteers were enrolled. Paired saliva and plasma samples were collected from all the participants. Consecutive saliva samples from 9 patients were collected every 4 hours following treatment. Treponema pallidum DNA in samples was determined by nested PCR and droplet digital PCR targeting polA and Tpp47.

Treponema pallidum DNA detection rates in saliva and plasma were 31.0% (9/29) and 51.7% (15/29) in primary syphilis(p=0.11), 87.5% (63/72) and 61.1% (44/72) in secondary syphilis(p<0.001), 25.6%(21/82) and 8.5%(7/82) in latent syphilis (p=0.004), 21.6%(11/51) and 5.9%(3/51) in symptomatic neurosyphilis (p=0.021), respectively. The loads of Tpp47 and polA in saliva were median 627 copies/ml (range, 0-101200 copies/ml) and median 726 copies/ml (range, 0-117260 copies/ml) for syphilis patients, respectively. In plasma, however, the loads of Tpp47 and polA were very low median 0 copies/ml (range, 0-149.6 copies/ml) and median 0 copies/ml (range, 0-176 copies/ml), respectively. The loads of Treponema pallidum DNA in saliva during treatment were fluctuating downward, and the clearance time was positively correlated with the loads of Treponema pallidum DNA before treatment.

The collection of saliva is noninvasive and convenient. The high loads of Treponema pallidum DNA in saliva and the reduction after treatment indicated that saliva can be not only a diagnostic fluid for syphilis, but also an indicator of therapeutic effectiveness.

Given evidence for the role of the prefrontal cortex in such diseases, it is significant that studies in humans and animal models have shown that prenatal protein malnutrition specifically affects functions associated with prefrontal cortex. However, the neural basis underlying these changes is unclear. In the current study, prenatally malnourished and control rats performed a sustained attention task with an unpredictable distractor, a task that depends on intact prefrontal cortical function. Radiolabeled 2-deoxyglucose was used to measure neural and brain network activity during the task. Results confirmed that adult prenatally malnourished rats were more distractible than controls and exhibited lower functional activity in prefrontal cortices. Thus, prefrontal activity was a predictor of task performance in controls but not prenatally malnourished animals.
