High-Uniform and High-Efficient Colour Alteration Nanoporous GaN-Based Micro-LED Present together with Inserted Quantum Dots.
y in ACLR of >12 months increased the risk of cartilage and MM injuries, whereas a delay of >6 months increased the risk of abnormal prereconstruction laxity and reduced the likelihood of MM repair. To reduce meniscus loss and the risk of jeopardizing knee laxity, ACLR should be performed within 6 months after the injury.

To present clinical results according to tunnel overlap in 1-stage anatomical revision anterior cruciate ligament reconstruction (ACLR).

All patients who underwent revision ACLR performed by a single surgeon (J.H.A.) from 2012 to 2017 and were followed up for >24 months were retrospectively evaluated. The exclusion criteria were concomitant ligament injury, including medial collateral ligament injury, modified Outerbridge grade ≥3 cartilage lesion, and severe meniscus defects. Tunnel overlap was measured on 3-dimensionally reconstructed computed tomography images. Patients in the nonoverlapped femoral tunnel group (group NO, n= 52) were treated with new tunnel drilling that completely avoided previous tunnels, and those in the overlapped femoral tunnel group (group O, n= 41) were treated with a new tunnel that overlapped with previous tunnels. Clinical outcomes were evaluated using the subjective International Knee Documentation Committee (IKDC) and Lysholm scores. Knee joint stability was measured usiohort study.
Level III, cohort study.
Bronchial asthma has not been adequately assessed in coronavirus disease 2019 (COVID-19). Respiratory allergy is associated with significant reductions in the expression of angiotensin-converting enzyme 2 receptor, which is the entry receptor for COVID-19.

To observe COVID-19 susceptibility in patients with bronchial asthma, analyze the prevalence of asthma in a large cohort of consecutive outpatient subjects who were tested with the RT-PCR assay for COVID-19.

This was a retrospective population-based cross-sectional study using data from a large nationwide health maintenance organization in Israel. All health maintenance organization enrollees who had been tested for COVID-19 from February to June 2020 were included. Differences in demographic and clinical characteristics between the subjects with negative and positive COVID-19 RT-PCR test results and between COVID-19 RT-PCR-positive subjects with and without asthma were analyzed.

A total of 37,469 subjects were tested for COVID-19 RT-PCR, and results for 2,266 (6.05%) of them were positive. A significantly higher proportion of smokers was observed in the COVID-19-negative group than in the COVID-19-positive group (4734 [13.45%] vs 103 [4.55%]; P < .001). Asthma was found in 153 (6.75 %) subjects of the COVID-19-positive group and in 3388 (9.62%) subjects of the COVID-19-negative group (P < .001). No significant impact of antileukotrienes, inhaled corticosteroids, and long-acting beta-blockers use was revealed on COVID-19 positivity proportions. Multiple logistic regression analysis adjusted for sex, age, smoking, and comorbidity revealed a negative association of asthma with the likelihood of being positive for COVID-19 (odds ratio, 0.71; 95% CI, 0.58-0.87; P= .001).

We observed lower COVID-19 susceptibility in patients with preexisting asthma.

Since drugs currently used to manage pain and inflammatory conditions present several side effects, the investigation of new anti-inflammatory and antinociceptive agents from folk-medicine plants is an important approach. Costus spiralis (Costaceae) has been used in Brazilian medicinal teas to treat urinary infection, cough, inflammation, arthritis, among others.

The current study focused on investigating anti-inflammatory and antinociceptive effects of fractions from C. spiralis leaves using animal models.

Adults Swiss mice were used in the following experimental models acetic acid-induced abdominal writhing, formalin-induced nociception, hot plate, zymosan-induced peritonitis, and arthritis induced by complete Freund's adjuvant.

The presence of steroids was confirmed in all fractions. Flavonoids, condensed tannins and saponins were observed in EFL. In methanolic fraction leaves (MFL), the presence of flavonoids and pentacyclic triterpenoids was confirmed. Orally administered leaf fractions significaults show that leaf fractions of Costus spiralis are capable of modulating peripheral nociceptive and inflammatory responses without effects on central nervous system being potential substrates for phytochemical purification, structural and mechanistic studies.
The dried rhizome of Cimicifuga heracleifolia Kom. (C. heracleifolia) is a popular traditional Chinese medicine, which has been extensively used in Asian countries for its anti-inflammatory, antipyretic and analgesic activities. However, further utilization and application of C. heracleifolia have been hampered due to a lack of full understanding of its active ingredients.

The present study aims for clarification of the systematical chemical profile of C. heracleifolia and the immunomodulatory effect of its main bioavailable component.

Comprehensive chemical profile of C. heracleifolia was systematically analyzed by ultra-performance liquid chromatography hyphenated with quadrupole time-of-flight tandem mass spectrometry (UPLC-Q-TOF/MS). Xenobiotics after oral administration of C. heracleifolia extracts were investigated to hunt for bioavailable components. The immunomodulatory activity evaluation of cimigenoside was achieved on poly(IC)-induced airway inflammation mouse and BEAS-2B cell models from asp induced by poly(IC).

Triterpene glycosides were the main components of C. heracleifolia extract, and cimigenoside was considered as the effective component with immunomodulatory effect on the pulmonary immune system by oral administration.
