Objective: To investigate human cytomegalovirus (HCMV) and Epstein-Barr virus-type 1 (EBV-1) in GCF and saliva during experimental gingivitis in Chinese young subjects and to evaluate the effect of the virus in the initial stage of gingival inflammation.
Methods: GCF of 14 and 45 and saliva without stimulating in 11 Chinese young males with healthy gingiva were collected at baseline (day 0), day 7, 14 and 21 after stopping oral hygiene and day7 after reestablishing oral hygiene (day 28). DNA of HCMV and EBV-1 were detected by nested-polymerase chain reaction (n-PCR) at the times mentioned above.
Results: HCMV was detected in GCF of 4 subjects at baseline, 4 subjects at day 7, 3 subjects at day 14 and 2 subjects at day 21 while the subjects were different. At day 28 HCMV could not be detected. EBV-1 was not detectable in GCF during the experimental gingivitis. HCMV was detected in saliva in 4 subjects and EBV-1 was in 3 subjects. And there is no relationship between the detection of the herpesviruses and the clinical parameters as well.
Conclusion: We suggest that HCMV and EBV-1 are not the important factors during the initial stage of gingival inflammation.

Impella versus Non-Impella for Non-emergent High-Risk Percutaneous Coronary Intervention: Impella vs. Non-Impella for HR-PCI.

Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.
Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).

Globally, domestic refrigerators account for over 13% of the total energy consumption in residential buildings. The brazed plate water-cooled condenser (BPWCC) is compact in size and an attractive option to reduce the energy consumption of refrigerators using domestic water tanks. This study evaluated the performance of a household refrigerator with a secondary refrigerant calorimeter and BPWCC, using an appropriate experimental setup.

Coughing is a symptom of many respiratory diseases. An increased amount of coughs may signal an (upcoming) health issue, while a decreasing amount of coughs may indicate an improved health status. The presence of a cough can be identified by a cough classifier.

Numerous conditions, both physiological and pathological, can influence changes in the retinal vascular architecture. In order to be able to highlight pathological aspects of systemic diseases with ocular activity, it is necessary to understand how physiological fluctuations can influence circulation at the retinal level. The present study attempts to evaluate retinal and choroidal vascular and structural changes in healthy female subjects over the course of a menstrual cycle using OCT-A.

The early immune kinetics after SARS-CoV-2 vaccination remain poorly understood, particularly among individuals with low-count monoclonal B-cell lymphocytosis (MBL). We investigated the cellular and humoral kinetics in the blood of 50 non-MBL healthy donors (HD) vs. 16 MBL subjects after SARS-CoV-2 vaccination, who were subclassified according to their history of previous exposure to SARS-CoV-2 into SARS-CoV-2 naïve and previously infected subjects.
