Authors: Li Liang , Wang Xizhou , Tang Shaoyue , Wang Jianfeng 
Published: June 2023

BackgroundIn recent years, the issue of problematic Internet pornography use (PIPU) among adolescents has become increasingly prominent, attracting widespread attention from society. Family functioning has been recognized as a protective factor for PIPU, but the underlying mediating and moderating mechanisms remain unclear. The purpose of this study is (a) to investigate the mediating role of self-esteem in the relationship between family functioning and PIPU, and (b) to examine the moderating role of the need to belong in this mediating pathway.MethodsA total of 771 high school students (Mage = 16.19, SD = 0.90) were surveyed using the Problematic Internet Pornography Use Scale, Family Assessment Device, Rosenberg Self-Esteem Scale, and the Need to Belong Scale.ResultsCorrelation analysis showed a significant negative correlation between family functioning and PIPU (r = −0.25, p &lt; 0.001), a significant positive correlation between self-esteem and family functioning (r = 0.38, p &lt; 0.001), a significant negative correlation between self-esteem and PIPU (r = −0.24, p &lt; 0.001), and a significant positive correlation between need to belong and PIPU (r = 0.16, p &lt; 0.01). Mediation analysis showed that self-esteem partially mediated the relationship between family functioning and PIPU, with a mediation effect of −0.06. Further moderated mediation analysis showed that for adolescents with higher need to belong, the mediating effect of self-esteem was stronger.ConclusionsFor adolescents with high belonging needs who are at high risk for PIPU, good family functioning may have a protective effect by boosting self-esteem.

BackgroundThe International Association for the Study of Lung Cancer defined types of surgical resection and considered the positivity of the highest mediastinal lymph node resected a parameter of “uncertain resection” (R-u). We investigated the metastases in the highest mediastinal lymph node, defined as the lowest numerically numbered station among those resected. We aimed to evaluate the prognostic value of R-u compared with R0.Materials and methodsWe selected 550 patients with non-small cell lung cancer at clinical Stage I, IIA, IIB (T3N0M0), or IIIA (T4N0M0) undergoing lobectomy and systematic lymphadenectomy between 2015 and 2020. The R-u group included patients with positive highest mediastinal resected lymph node.ResultsIn the groups of patients with mediastinal lymph node metastasis, we defined 31 as R-u (45.6%, 31/68). The incidence of metastases in the highest lymph node was related to the pN2 subgroups (p &lt; 0.001) and the type of lymphadenectomy performed (p &lt; 0.001). The survival analysis compared R0 and R-u: 3-year disease-free survival was 69.0% and 20.0%, respectively, and 3-year overall survival was 78.0% and 40.0%, respectively. The recurrence rate was 29.7% in R0 and 71.0% in R-u (p-value &lt; 0.001), and the mortality rate was 18.9% and 51.6%, respectively (p-value &lt; 0.001). R-u variable showed a tendency to be a significant prognostic factor for disease-free survival and overall survival (hazard ratio: 4.6 and 4.5, respectively, p-value &lt; 0.001).ConclusionsThe presence of metastasis in the highest mediastinal lymph node removed seems to be an independent prognostic factor for mortality and recurrence. The finding of these metastases represents the margin of cancer dissemination at the time of surgery, so it could imply metastasis into the N3 node or distant metastasis.

IntroductionBrucellosis is a zoonotic disease with worldwide distribution. It is considered endemic in Eritrea, however, the current prevalence status and related risk factors in animals are unknown. The objective of this study was to determine the prevalence of and risk factors for brucellosis in dairy cattle in Maekel and Debub regions, Eritrea.MethodsA cross sectional study was conducted between August 2021 and February 2022. A total of 2,740 dairy cattle from 214 herds in 10 sub-regions of Eritrea were selected for blood and data collection. Blood samples were tested using Rose Bengal Plate Test (RBPT) and positive samples were confirmed using competitive (c-ELISA). Data on risk factors was collected using questionnaire and analyzed using logistic regression.ResultsIn total, 34/2740 animals tested positive by RBPT. Of these, 29 were confirmed positive by c-ELISA, giving an apparent and estimated true individual-level prevalence of 1.1% (95% CI: 0.7, 1.5%) and 1.3% (95% CI: 0.9, 1.8%), respectively. Sixteen herds (7.5%) tested positive by RBPT and of these 15 herds (7.0%) were confirmed positive by c-ELISA, giving an estimated true herd-level prevalence of 7.0% (95% CI: 4.0, 10.7). Animal and herd-level apparent prevalence was 1.6 and 9.2% in Maekel, while in Debub it was 0.6 and 5.5%, respectively. Multivariable regression analysis indicated that non-pregnant lactating cows (adjusted odds ratio [aOR] = 3.35; p = 0.042) were more likely to be Brucella sero-positive. History of abortion on the farm (aOR = 5.71; p = 0.026) and larger number of cows in the herd (aOR = 1.14; p &lt; 0.001) were associated with brucellosis sero-positivity in herds.ConclusionBrucellosis prevalence was low in the study areas. Nonetheless, this low prevalence may increase if the disease is not controlled. Therefore, testing animals before movement, good farming practices, sanitary measures, and an awareness raising program on brucellosis are recommended.

IntroductionPorcine circovirus type 2 (PCV2) is the primary etiological agent of porcine circovirus diseases (PCVD), which are widespread in most pig herds, causing huge economic losses in the global pig industry. Therefore, it is critical to assess the infection characteristics of PCV2 in different swine herds to develop effective strategies against PCVD.MethodsIn this study, routine diagnostic and monitoring protocols were used to collect 12,714 samples from intensive farms in China, and PCV2 was tested for by qPCR to determine positivity rates and viral loads in samples from different herds and materials.ResultsPCV2 was found to be prevalent throughout China, and fattening farms had higher positivity rates than breeding farms. The PCV2 positivity rates in breeding farms in Southern China were higher than those in Northern China. Growing–finishing pigs demonstrated the highest positivity rate in the tested samples, while pre-weaning piglets and adult sows had the lowest. Meanwhile, samples with viral loads exceeding 106 copies/mL in growing–finishing pigs had 27.2% positivity, compared to 1.9% and 3.3% in sows and piglets, respectively. The results of the viral loads in the serum samples followed a similar trend.DiscussionThe findings reveal that PCV2 circulates in different herds from intensive farms, with positivity increasing from pre-weaning to growing–finishing herds. It is urgent to develop effective strategies to reduce PCV2 positivity in growing–finishing herds and prevent viral circulation among pigs.
A Relationship between Changes of Surface Air and Sea Floor Temperatures at the Arctic Shelf from the Coupled Models Intercomparison Project, Phase 6 Data
Authors: Malakhova Valentina V. , Eliseev Alexey V. 
Published: June 2023

The sensitivity of seafloor temperature TB to the warming of surface air temperature Ta is examined for 1850–2300, based on simulations with five models from the Coupled Models Intercomparison Project phase 6 ensemble and driven by a scenario with high anthropogenic emissions of greenhouse gases. In this historical period (until 2015), sensitivity coefficients α=ΔTB/ΔTa (Δ indicates changes relative to the pre-industrial period) were typically ≤0.12 for annual means and up to 0.43 in summer. However, during the same period in the Barents Sea sector, the sensitivity coefficients were as large as 0.6 in summer. For summer, the obtained results are consistent with the limited measurements available for the Siberian shelf. In future, sensitivity coefficients will increase markedly, and α≥0.7 will become common for the part of the Arctic shelf that becomes ice-free in summer. Our results have implications for estimating the future thermal state of subsea sediments, as well as for oceanic biota.

Relevance. According to the latest international classification of periodontal diseases of 2018, smoking, along with diabetes mellitus, belongs to the main modifying factors of the periodontitis course. At the same time, the clinical signs of gingival inflammation in smokers are not very pronounced.The study aimed to determine significant clinical indicators of gingival inflammation in tobacco-dependent peri- odontal patients.Materials and methods. The study interviewed and examined 82 patients with generalized periodontitis aged 20 to 63 years. Patients with diabetes mellitus were excluded. The examination evaluated the caries prevalence (DMFT index), the degree of periodontal attachment loss, the periodontitis progression type by an indirect indicator, oral hygiene status (Green-Vermilion index), tooth mobility (D.A. Entin), bleeding on probing (Mühlemann modified by Cowell; Ainamo, Wow). Based on their attitude to smoking, patients were randomized into three groups: the first group consisted of 18 patients who smoked up to 10 cigarettes per day; the second group included 15 patients who smoked 10-20 or more cigarettes per day; and the third group (comparison group) consisted of 18 non-smokers.Results. The oral hygiene status, caries prevalence, the number of extracted teeth, the mobility of remaining teeth and the bleeding on probing score appeared to be the same in non-smoking and smoking periodontal patients. However, the number of patients with severe periodontitis was statistically significantly higher in heavy smokers with periodontitis (more than ten cigarettes per day); every other patient had comorbidity, rapid progression of the disease, and the clinical indicator of gingival inflammation based on the prevalence of bleeding on probing was at 100%.Conclusion. We believe that the prevalence of bleeding on probing should be the main parameter for gingival inflammation assessment in smokers, which allows for the objective follow-up of the process progression in such patients and motivation for treatment and smoking cessation.

Relevance. The work presents the results of a comprehensive dental examination of patients with vermilion and oral mucosa proper (OM) diseases associated with manifestations of Crohn's disease (CD) and ulcerative colitis (UC).Aim. To determine the cause-related features of complaints and clinical manifestations of vermilion and OM diseases.Material and methods. The comprehensive dental examination included the analysis of complaints, history, and assessment of the vermilion and OM condition and the nociceptive pain severity score according to the Visual Analog Scale (VAS).Results and discussion. In CD and UC, the vermillion diseases clinically manifested in 51.43% and 42.85% of subjects (p < 0.01), OM chronic trauma – in 40.0% and 31.43% (p < 0.05), chronic recurrent aphthae – in 48.47% (p < 0.001) and 31.43% (p < 0.01), glossitis – in 62.86% (p < 0.001) and 25.71% (p < 0.01), glossodynia – in 31.43% (p < 0.01) and 17.15% (p < 0.05) of cases. The main complaints of patients with the detected OM pathology included unpleasant sensations, like rawness and soreness, on taking irritating foods in 100% and 65.71% and talking in 31.43% and 25.71% of cases, dry mouth in 51.43% and 25.71% of cases. The burning mouth syndrome was in 31.43% and 17.15% of patients.Conclusion. The vermilion and the oral mucosal diseases often prevail associated with the clinical course of Crohn'sdisease compared to patients with UC. The VAS pain severity score hinges on CD and UC course (p < 0.055). The variety of clinical manifestations of the vermillion and oral mucosal diseases directly depends on CD and UC, a criterion for developing an integrated approach to their diagnosis and implementing recommendations for their prevention and treatment in practical health care.

Relevance. The issue of oral mucosa and bone tissue restoration after tooth extraction and other dental interventions determines the study's relevance. The article presents experimental study results of regeneration processes in the animal oral mucosa and bone tissue wound surface during two operations: tooth extraction without bone structure and material grafting and tooth extraction with autologous dental tissue grafting.Material and methods. The study included 24 laboratory male Wistar rats divided into two groups. The animals of the main group underwent tooth extraction followed by simultaneous autologous tissue grafting into the extracted tooth socket. The autograft consisted of the tissues of a particulated tooth previously removed from the subject. Animals of the control group underwent tooth extraction without bone structures and material grafting.Results. On day 21, all study groups showed complete oral mucosa regeneration in the extracted tooth area. After 1.5 months of control group observation, the socket floor was filled with mature granulation tissue, transforming into fibrous tissue. The main study group demonstrated bone formation by autograft replacement in the coarse fibrous tissue growth thickness. After three months of observation, the control group showed bone atrophy at the extracted tooth site. In the main study group, there was newly formed bone tissue, which had replaced the autograft.Conclusion. The conducted experimental study demonstrates that autologous particulated dental tissue grafting leads to active new bone formation, which the histology results confirmed in 21 days, 1.5 and 3 months of followup observation.

Relevance. Gum recession is a pathology often encountered both in Russia and worldwide. Modern surgical methods allow for the complete elimination of recession signs when adequately choosing strategy, tactics, methodology and surgical treatment protocol; for complication prevention and stable long-term outcome. Autograft and allogeneic dura mater as a grafting material for creating/increasing the volume of the attached gingiva in recession treatment have comparable results in all clinical indications. The reason for result stability and the absence of relapse is poorly studied; the data are scarce and do not give a full understanding. In the scientific literature, we did not encounter histological tissue composition analysis in the graft placement area. In recession coverage, the graft is partially placed subperiosteally (in the tooth root area) and partially in the thickness of the soft tissues of the gum. Purpose. The study aimed to determine the histological composition of tissues in the dura mater placement area, to compare with the control group without a graft, and to assess follow-up changes in the graft and surrounding tissue reaction as a result of cellular-level surgery.Material and methods. A laboratory histomorphological examination involved 60 laboratory rats. All underwent surgery adequate to gum recession surgical treatment technique: the control group had no graft, and the study group had allogeneic dura mater. The samples were collected on the 3rd, 7th, 14th, 28th, 90th and 107th days after surgery.Results. In all cases, the tissue complex regenerated, and the reaction to the operation was the same. The plastic material replacement was at the same period. Bone tissue replaced subperiosteally placed graft, connective tissue intragingivally. Gingival biotype thickening was considerably due to the surgical trauma, less – from the graft material. Allogeneic dura mater stimulated earlier ossification.Conclusion. In all cases, the use of grafting material for surgical gum recession coverage is justified if placed subperiosteally, forming a full-thickness mucoperiosteal flap surgically (with a scalpel) to preserve the cambium periosteum on the flap. Bone volume and buccal cortical plate reconstruction/ regeneration support soft tissues of the newly formed ligament of the tooth and prevent recurrent recession formation. The formation of bone and connective tissues in the dura mater placement area determines the result stability of gingival recession surgical treatment and a long-term favourable prognosis without complications and relapse.

Abstract
Recent progress in α-phase gallium oxide (α-Ga2O3) grown on sapphire for low-cost and practical device applications is reviewed. This review focuses on (i) dislocations formed by heteroepitaxy, (ii) p-type conductivity (a common issue with β-Ga2O3), and (iii) thermal instability due to the metastable phase of α-Ga2O3, and discusses efforts aimed at overcoming these issues. The results reveal guidelines for the dislocation density (<1 × 108 cm−2) so that the dislocation scattering is veiled in the electron transport, and for this purpose we mentioned buffer layers and epitaxial lateral overgrowth. Quasi-vertical Schottky barrier diodes (SBDs) show defect-insensitive behavior in current–voltage characteristics under a low current density. We also demonstrate the heterojunction pn diodes with α-phase iridium oxide (α-Ir2O3) or α-(Ir,Ga)2O3 and the ways to improve thermal stability of α-Ga2O3. The up-to-date device characteristics, that is, low on-resistance and large current SBDs, and high reverse voltage of 1400 V of a pn junction suggest promising development in α-Ga2O3-based devices.
Pityriasis Lichenoides; A Case Series With Clinical And Histological Evaluation In A Sample Of Sixteen Iraqi Patients In Najaf
Authors: Aldhalimi Dr. Muhsin , Alsalihi Mais 
Published: June 2023

Background: Pityriasis lichenoides is an uncommon papulosquamous disorder of an unknown etiology. The clinical spectrum consists of an acute ulcerative variant, pityriasis lichenoides et varioliformis acuta (PLEVA), and a chronic, non-ulcerative variant, pityriasis lichenoides chronica (PLC). A third, much more rare and aggressive form, febrile ulceronecrotic Mucha–Habermann disease (FUMHD), also occurs. Pityriasis Lichenoides is often benign, with a chronic course and with eventual spontaneous resolution over months to years. Objectives: The current study aims to evaluate the pityriasis lichenoides among patients attending Al-Sader medical city, Najaf, in the last five years, clinically and histologically. Patients and method: This is a case series performed retrospectively over the period from January 2017 through November 2021, in Najaf. Sixteen patients with clinical and histological PL were evaluated according to their medical records and online archives. A histopathological revision of their paraffin-embedded sections was also performed and statistically analyzed. Results: Sixteen patients with pityriasis lichenoides were evaluated; PLC was more common than PLEVA (14:2). PL mainly affects people in the second decade of life (37.5%). The age at the time of diagnosis ranged from 5 to 41 years, with a mean ±SD of 20.1± 9.9 years, which was higher for PLC (21.4±9.7) years than for PLEVA (11±7) years. Females outnumber males in PLC (9:5) as the only two reported cases of PLEVA were males. The skin phototype III was double that of type IV (11:5). More urban patients than rural patients were presented. The cases peak was in 2020 (31.25%), followed by 2021 (18.75). However, the clinical and histopathological features were classic and comparable to the published literature. Conclusion: PL is a disease predominant among young adults; more females were affected by PLC, while males were predominantly affected by PLEVA. More patients, who were more urban than rural, with skin phototype III were affected.
