Objectives: In this study, the authors aimed to evaluate the relationship between pericarotid fat density (PFD) and pathologic carotid plaque risk characteristics.

Methods: The authors retrospectively evaluated 58 patients (mean age: 66.66 ± 7.

[Healing effect of photodynamic therapy on extraction sockets of periodontally compromised teeth: a randomized, controlled, superiority clinical trial].

To evaluate the effects of photodynamic therapy (PDT) in extraction sockets of periodontally compromised molars on soft tissue healing, postoperative pain, bone density and bone height changes. This study is a single-center, single-blind, randomized controlled superiority clinical trial. Thirty-eight periodontally compromised molars requiring extraction in patients attending the Department of Periodontology, Stomatology Hospital, School of Stomatology, Zhejiang University School of Medicine, from December 2022 to September 2023 were included, and randomly assigned to PDT group and control group.

Deficiency Alters Subgingival Microbiota and Attenuates Periodontitis.

Periodontitis (PD) is the primary cause of tooth loss in adults. (), a keystone pathogen, has been identified as a crucial contributor to this process. Pyroptosis activation in PD is acknowledged, with accumulating evidence underscoring the crucial role of Caspase-11 (described as Caspase-4/5 in humans)-mediated noncanonical pyroptosis.

Fungicide Dissipation Kinetics and Dietary Exposure Risk Assessment in Squash Fruit and Leaf.

The dissipation behavior and dietary exposure risk assessment of four fungicides (dimethomorph, mandipropamid, myclobutanil, and metalaxyl) was performed in fruits and leaves of squash grown under greenhouse conditions. Squash fruit and leaf samples were randomly collected at 0, 3, 5, 7, and 14 days after the last pesticide application. Analysis was performed using ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS).

Characteristics and aetiology of low-temperature burns in Beijing of China.

This study was designed to analyse the characteristics and aetiology of low-temperature burns and explore the prevention and treatment strategies. In total, 206 patients hospitalised with low-temperature burns in a major burn center in Beijing from 2017 to 2021 were included. There were 35-49 cases per year, with an average of 41 ± 4.

Dissipation Kinetics and Risk Assessment of Spirodiclofen and Tebufenpyrad in Thunb.

The dissipation kinetics of spirodiclofen and tebufenpyrad after their application on Thunb were studied for 10 days, including the pre-harvest intervals. Spirodiclofen and tebufenpyrad were used in two greenhouses in Taean-gun, Chungcheongnam province (Field 1) and Gwangyang-si, Jeollanam province (Field 2), Republic of Korea. Samples were taken at 0, 1, 3, 5, 7, and 10 days after pesticide application.

Dissipation behavior and dietary exposure risk of pesticides in Brussels sprout evaluated using LC-MS/MS.

In this study, the dissipation behavior and dietary exposure risk of eight pesticides in Brussels sprout were evaluated under greenhouse conditions. Brussels sprout samples were collected 0, 7, 14, and 21 days after the last pesticide treatment. Ultra-high performance liquid chromatography with tandem mass spectrometry was used for sample analysis.

Serum syndecan-4 is associated with nonalcoholic fatty liver disease.

Objectives: The accelerated shedding of extracellular domains of syndecan-4 (SDC4) is associated with central obesity and insulin resistance, while the association between serum SDC4 and nonalcoholic fatty liver disease (NAFLD) is unknown. We aimed to examine the association between SDC4 and NAFLD.

Methods: Adults undergoing a health examination from 1 June 2019 to 31 December 2019 were enrolled.

[Study on the mechanical properties of sutures in the process of suturing].

Suture broken, knot slipping and tissue tearing are the main reasons of wound closure failure in clinical operation. Based on this, we simulated the suturing and healing operation by using a biological materials testing machine and investigated the tensile properties before and after knotting, relaxation property and friction property of three common sutures: silk, polyglactin 910 and polypropylene. Results show that the tensile property decreased after knotting.

In vivo adhesive behavior of human facial skin by a modified indentation test.

A better understanding of the adhesive behavior of human facial skin is important for dermatological or cosmetic applications. For their in vivo experimental characterization and analysis, the indentation test is an effective and widely used method. In this study, our independently developed transparent indenter and curved surface optical imaging technique are improved, by which the contact area of facial skin can be in vivo and in situ obtained during an indentation test.

[Long-term stability of periodontal root coverage procedures for gingival recession].

Gingival recession could result in root exposure, dental hypersensitivity and poor aesthetics. It has been demonstrated that varieties of root coverage procedures can significantly improve gingival recession in short-term (≤6 months), of which coronally advanced flap combined with connective tissue graft is the gold standard technique for treatment of gingival recession. It could obtain the optimally complete root coverage and maintain long-term stability (≥2 years).

Influence of Iron Supplementation on DMT1 (IRE)-induced Transport of Lead by Brain Barrier Systems in vivo.

Objective: To investigate the potential involvement of DMT1 (IRE) protein in the brain vascular system in vivo during Pb exposure.

Methods: Three groups of male Sprague-Dawley rats were exposed to Pb in drinking water, among which two groups were concurrently administered by oral gavage once every other day as the low and high Fe treatment group, respectively, for 6 weeks. At the same time, the group only supplied with high Fe was also set as a reference.

A shocking craniofacial penetrating injury by a steel bar.

Owing to the diversity in cause and damage, there is no standard surgical treatment method for a complicated penetrating craniofacial injury. The treatment of a complicated penetrating head injury caused by a steel bar is presented here. A 66-year-old woman fell onto a steel bar at a construction site and it penetrated the mandible, entered the sinus and orbital cavities, and reached the base of the frontal bone.
