Relatively high concentration of nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) in response to a variety of stimuli is a source of reactive nitrogen species, an important weapon of host innate immune defense. The SPRY domain-containing SOCS box protein 2 (SPSB2) is an E3 ubiquitin ligase that regulates the lifetime of iNOS. SPSB2 interacts with the N-terminal region of iNOS via a binding site on the SPRY domain of SPSB2, and recruits an E3 ubiquitin ligase complex to polyubiquitinate iNOS, leading to its proteasomal degradation. Although critical residues for the SPSB2-iNOS interaction have been identified, structural basis for the interaction remains to be explicitly determined. PI3K inhibitor drugs In this study, we have determined a crystal structure of the N-terminal region of iNOS in complex with the SPRY domain of SPSB2 at 1.24 Å resolution. We have resolved the roles of some flanking residues, whose contribution to the SPSB2-iNOS interaction was structurally unclear previously. Furthermore, we have evaluated the effects of SPSB2 inhibitors on NO production using transient transfection and cell-penetrating peptide approaches, and found that such inhibitors can elevate NO production in RAW264.7 macrophages. These results thus provide a useful basis for the development of potent SPSB2 inhibitors as well as recruiting ligands for proteolysis targeting chimera (PROTAC) design.

To assess, in a real-life setting, the effectiveness of telemonitoring adults with type 1 diabetes (T1D) using continuous glucose monitoring in a telemedicine experiment.

Experimentation in Telemedicine for the Improvement of Healthcare Pathways (ETAPES), an experimental telehealth programme for five chronic diseases, is supported by the French national healthcare system to promote telemedical care. Using data from a single university hospital centre, 72 adults were studied, including 42 subjects (58%) receiving insulin pump therapy and 30 (42%) receiving multiple daily injections, with a median age of 35.5 years [28.0; 45.0] and poorly controlled type 1 diabetes (T1D) with a mean ± standard error of mean (SEM) HbA1c value of 8.69 ± 0.13%. The primary study outcome was the difference in HbA1c values between baseline and the end of a 6-month follow-up. Other end points of interest were mean blood glucose, glucose management indicator (GMI) level and % time in range (3.9-10 mmol/L) or below or above range.

At month 6, mean HbA1c levels were significantly reduced by -0.5% (P < 0.001) as were also mean blood glucose levels (P = 0.015), with a significant increase of 6.75 ± 1.36% of time in range at month 3 and of 4.98 ± 1.4% at month 6. Such improvements did not depend on age, gender or type of insulin therapy, but were inversely correlated to initial HbA1c values on multivariate analysis (P < 0.001).

Although the use of telehealth monitoring offers efficacy and safety in the metabolic control of patients with T1D, it does not fulfil all of these patients' clinical needs. As such, this new healthcare pathway cannot replace, but is a useful complement to, face-to-face in-person clinical visits.

Periodontitis is a common chronic inflammatory disease prevalent in diabetes. The aim of this study was to evaluate periodontitis and poor oral hygiene as independent risk factors for either cerebral or myocardial infarction in the diabetes population.

This retrospective cohort study included 17,009 patients with diabetes who had participated in a nationwide health-screening programme, including oral health examination, during 2002-2003 in South Korea. Presence of periodontitis, tooth loss and carious teeth were assessed by professional dentists, and the number of tooth brushings per day was evaluated through self-reported questionnaires. The primary study outcome was the development of cerebral or myocardial infarction, based on International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10) codes, up to 31 December 2015.

The study enrolled 17,009 patients with diabetes. Over the mean 11.64 years of follow-up, 1341 patients presented with either cerebral or myocpopulation, and improved oral hygiene would probably be associated with lower cardiovascular risk in diabetes.Production of valuable compounds including biofuels and pharmaceutical precursors derived from microalgae has garnered significant interest. Stable production of algal biomass is essential to make the microalgal industry commercially feasible. However, one of the largest issues is severe biological contamination by predators grazing the algal biomass, resulting in the crash of outdoor cultures. In the present study, we propose a novel engineering strategy for microalgae to cope with predators. The overexpression of plant chlorophyllase (CLH) in a microalga resulted in the enhancement of resistance to the predator. This result supported our hypothesis that CLH promotes chlorophyll breakdown in the chloroplasts of the microalgae when they are digested by the predator, generating the phototoxic catabolite chlorophyllide that damages the predator. To the best of our knowledge, this is the first study to establish predator-resistant microalgae by enhancing the CLH activity.

To evaluate the current status of women interventional radiologists in China and discuss possible measures to boost their representation in this male-dominated field for a more diverse workplace environment in the future.

The list of Chinese interventional radiologists obtained from the Chinese College of Interventionalists was retrospectively reviewed. Key information was extracted from the database, including sex, chronologic trends of representation of women interventional radiologists, position, education level, geographic distribution, interventional radiology (IR) practice time, departmental affiliation, and hospital classification.

Of the 13,855 entries, 7,324 (52.9%) were interventional radiologists having valid information. Among them, 684 (9.3%) were identified as women. The number of women interventional radiologists has continued to increase since the first woman registered in 1992. The average age of women interventional radiologists was 39.1 years ± 5.7 (range, 26-50). The majority of them were attending physicians (n= 280; 40.
