Validation of the Short Version (TLS-15) of the Triangular Love Scale (TLS-45) across 37 Languages.

Love is a phenomenon that occurs across the world and affects many aspects of human life, including the choice of, and process of bonding with, a romantic partner. Thus, developing a reliable and valid measure of love experiences is crucial. One of the most popular tools to quantify love is Sternberg's 45-item Triangular Love Scale (TLS-45), which measures three love components: intimacy, passion, and commitment. However, our literature review reveals that most studies (64%) use a broad variety of shortened versions of the TLS-45. Here, aiming to achieve scientific consensus and improve the reliability, comparability, and generalizability of results across studies, we developed a short version of the scale-the TLS-15-comprised of 15 items with 5-point, rather than 9-point, response scales. In Study 1 (N = 7,332), we re-analyzed secondary data from a large-scale multinational study that validated the original TLS-45 to establish whether the scale could be truncated. In Study 2 (N = 307), we provided evidence for the three-factor structure of the TLS-15 and its reliability. Study 3 (N = 413) confirmed convergent validity and test-retest stability of the TLS-15. Study 4 (N = 60,311) presented a large-scale validation across 37 linguistic versions of the TLS-15 on a cross-cultural sample spanning every continent of the globe. The overall results provide support for the reliability, validity, and cross-cultural invariance of the TLS-15, which can be used as a measure of love components-either separately or jointly as a three-factor measure.

Exploring Attitudes Toward "Sugar Relationships" Across 87 Countries: A Global Perspective on Exchanges of Resources for Sex and Companionship.

The current study investigates attitudes toward one form of sex for resources: the so-called sugar relationships, which often involve exchanges of resources for sex and/or companionship. The present study examined associations among attitudes toward sugar relationships and relevant variables (e.g., sex, sociosexuality, gender inequality, parasitic exposure) in 69,924 participants across 87 countries. Two self-report measures of Acceptance of Sugar Relationships (ASR) developed for younger companion providers (ASR-YWMS) and older resource providers (ASR-OMWS) were translated into 37 languages. We tested cross-sex and cross-linguistic construct equivalence, cross-cultural invariance in sex differences, and the importance of the hypothetical predictors of ASR. Both measures showed adequate psychometric properties in all languages (except the Persian version of ASR-YWMS). Results partially supported our hypotheses and were consistent with previous theoretical considerations and empirical evidence on human mating. For example, at the individual level, sociosexual orientation, traditional gender roles, and pathogen prevalence were significant predictors of both ASR-YWMS and ASR-OMWS. At the country level, gender inequality and parasite stress positively predicted the ASR-YWMS. However, being a woman negatively predicted the ASR-OMWS, but positively predicted the ASR-YWMS. At country-level, ingroup favoritism and parasite stress positively predicted the ASR-OMWS. Furthermore, significant cross-subregional differences were found in the openness to sugar relationships (both ASR-YWMS and ASR-OMWS scores) across subregions. Finally, significant differences were found between ASR-YWMS and ASR-OMWS when compared in each subregion. The ASR-YWMS was significantly higher than the ASR-OMWS in all subregions, except for Northern Africa and Western Asia.

How Does Pregnancy and Type of Delivery Affect the Clinical Course of Hereditary Angioedema?

INTRODUCTION: Knowledge on the clinical course of hereditary angioedema (HAE) during pregnancy, delivery, and breastfeeding is very limited. In this study, we aimed to evaluate the course of HAE during these periods. METHODS: The HAE attacks C1-INH prophylaxis before and during pregnancy and during breastfeeding, and the delivery types were retrospectively determined. The severity of attacks was assessed by a 10-point Visual Analogue Scale (VAS). RESULTS: We evaluated 88 pregnancies in 48 HAE patients among whom 20 were primiparous. Among those who had a HAE diagnosis during pregnancy (n = 34), the median attack numbers before pregnancy, during pregnancy, breastfeeding, and after breastfeeding were 17, 39, 24, and 14 (before pregnancy vs. pregnancy, p < 0.001; during pregnancy vs. breastfeeding, p = 0.001). The mean VASs (SD) were 6.59 (1.82), 8.33 (1.58), 7.32 (1.66), and 6.95 (1.90) (before pregnancy vs. pregnancy, p < 0.001; during pregnancy vs. breastfeeding, p = 0.016), respectively. Among those who received a HAE diagnosis after pregnancy (n = 54), the number (59.3%) and the severity (60%) of HAE attacks were high in pregnancy. 47 of the deliveries were normal vaginal delivery (NVD). Regional anesthesia was applied in 8 NVDs. 20 of caesarean deliveries were performed under general anesthesia, and 21 were under spinal anesthesia. Lowest numbers of attacks were found in patients who did not receive anesthesia during NVD (p = 0.001). CONCLUSION: The course of HAE can be worse during pregnancy and breastfeeding. NVD is related to fewer HAE attacks and prophylaxis with C1-INH during NVD is not necessary to prevent a HAE attack.

Calculated Globulin Is Clinically Useful as a Screening Test for Antibody Deficiency in Turkish Adult Patients.

INTRODUCTION: Heterogeneous clinical features of antibody deficiency (AD) may cause diagnostic delays. Calculated globulin (CG) (total protein minus albumin) has been proposed as a screening test to prevent morbidity due to diagnostic delays in AD. Our aim was to validate CG as a screening test for AD in Turkish adult patients by comparing its role with gamma globulin analysis in protein electrophoresis. METHODS: Fifty serum samples were randomly collected for each level of CG from 15 to 25 g/L and tested for serum IgG, IgA, IgM levels and protein electrophoresis. Cut-off values predicting low IgG levels were calculated for electrophoretically determined gamma globulin and CG. Additionally, the data of 47 patients followed up in our clinic with a diagnosis of primary antibody deficiency (PAD) were retrospectively analyzed. RESULTS: A total of 550 adult patients were included in the study. The CG value predicting patients with IgG <6 g/L as a screening test was determined as <20 g/L with 83.8% sensitivity and 74.9% specificity. The gamma globulin value which predicted patients with the same IgG value of 89.0% sensitivity and 89.4% specificity was determined as <7 g/L. In the retrospective analysis, 37 of 47 patients (78.7%) with PAD had a CG value of <20 g/L at the time of the diagnosis and all 13 patients (100%) whose gamma globulin values were measured at the time of the diagnosis had a gamma globulin value of <7 g/L. CONCLUSION: The determined CG cut-off value of <20 g/L can be used as a screening test in Turkish adult patients.

The evaluation of melatonin levels in chronic spontaneous urticaria: A case control study.

Background: Although sleep disturbance is known to be common in patients with chronic spontaneous urticaria (CSU), sleep hormone levels in the blood have never before been studied in CSU. Objective: In this study, we aimed to evaluate the serum melatonin levels in patients with CSU. Methods: For the patient group, 80 patients with recently diagnosed CSU, and, for the control group, 75 healthy controls (HC) were included. The study participants' melatonin levels were measured by using the enzyme-linked immunosorbent assay method. CSU disease activity was evaluated by using the urticaria activity score-7 (UAS-7), and the quality of life was assessed with the chronic urticaria quality of life questionnaire (CU-Q2oL). The patients with concomitant diseases likely to affect the melatonin levels or those using related medications were excluded from the study. Results: The patient group consisted of 53 female subjects (67%); the median (interquartile range) age was 34 years (27-43 years). The levels of melatonin were lower in the patients with CSU when compared with the HCs (p < 0.03). The melatonin levels had no significant relationship between UAS-7 and the total scores in CU-Q2oL (p > 0.05). However, a significant negative correlation in the melatonin levels was observed with questions 7 (overall sleep assessment) and 11 (difficulty in falling into sleep) in the CU-Q2oL (r = -0.55 [p < 0.001] and r = -0.62 [p < 0.001], respectively). Conclusion: The presence of low melatonin levels in the patients with CSU suggests that melatonin has a key regulatory role in the CSU development in addition to the deterioration in sleep quality. A new treatment strategy to increase the melatonin levels in CSU may be pursued in further studies to confirm our findings.

How important is patch testing with dental materials in real-life clinical practice?

Background: Allergy to dental materials in prostheses and implants that leads to dental device dysfunction is a challenging problem. Objective: In this prospective study, we aimed to investigate the diagnostic role and impact of dental patch test (DPT) results on the outcome of proceeding dental procedures with the collaboration of our allergy clinic and dental clinics. Methods: A total of 382 adult patients with oral or systemic signs or symptoms due to the applied dental materials were included. A DPT with 31 items was administered. The clinical findings after dental restoration according to the test results were assessed in the patients. Results: The most common positivity detected in the DPT was due to metals, among which nickel (29.1%) was the leading cause. The frequency of self-reported allergic diseases and metal allergy was significantly higher in patients with at least one positive result in the DPT (p = 0.004 and p < 0.001, respectively). Clinical improvement after the removal of dental restoration was seen in 82% of the patients who had a positive DPT result, whereas this rate was 54% among paatients with negative DPT results (p < 0.001). The only factor that predicted improvement after restoration was the positivity in the DPT result (odds ratio 3.96 [95% confidence interval, 0.21-7.09]; p < 0.001). Conclusion: Our study showed that a self-reported metal allergy was an important finding to predict allergic reactions to dental devices. Therefore, patients should be questioned for the presence of metal allergy-related signs and symptoms before exposure to the dental materials to prevent possible allergic reactions. Furthermore, DPT results are valuable to guide dental procedures in real life.

Common but neglected problem in chronic spontaneous urticaria: Sleep disturbance.

Background: Association of chronic spontaneous urticaria (CSU) with sleep disturbance has not been evaluated in studies that involve a large number of patients. Objective: In this study, we aimed to evaluate the sleep attitude and circadian rhythm in patients with CSU. Methods: As the patient group, recently diagnosed 100 patients with CSU, 100 patients with allergic rhinitis (AR) as the patient control group, and 100 healthy controls (HCs) were included. The Pittsburgh Sleep Quality Index (PSQI) questionnaire, sleep hygiene index (SHI), Epworth Sleepiness Scale (ESS) questionnaire, and the morningness-eveningness questionnaire (MEQ) were filled to assess sleep quality and circadian rhythm. CSU disease activity was evaluated by urticaria activity score-7 (UAS-7). Patients with concomitant diseases, e.g., psychiatric illnesses, that possibly affect sleep status or those who use related medications and at moderate or high risk of obstructive sleep apnea according to the STOP-Bang questionnaire were excluded from the study. Results: PSQI, SHI, and ESS scores were higher, and the MEQ score was lower in patients with CSU and patients with AR than those in the HCs (p < 0.001, for each score). However, the scores were not different among the patients with CSU and the patients with AR. UAS-7 was only correlated with PSQI scores (r = 0.402, p < 0.001). In addition, blood eosinophil counts and the serum C Reactive Protein (CRP) level were correlated with sleep quality (p = 0.02). Conclusion: The poor sleep quality, impaired sleep hygiene, increased daytime sleepiness, and intermediate type of circadian rhythm were observed in the patients with CSU and the patients with AR. Physicians should be aware of sleep problems in patients with CSU that might affect their quality of life and the success of their treatment.

Quercetin and Luteolin Improve the Anticancer Effects of 5-Fluorouracil in Human Colorectal Adenocarcinoma In Vitro Model: A Mechanistic Insight.

The aim of this study was to investigate the antitumor effects of quercetin and luteolin combined with 5-Fluorouracil (5-FU) in HT-29 human colorectal cancer cells. Cell viability induced by quercetin, luteolin and combination of these compounds with 5-FU were determined by MTT assay, also Cell death detection Elisa assay and fluorescence microscopy were performed to investigate apoptotic effects. Hu-VEGF Elisa assay was employed to determine the effects of treatments on angiogenesis. Western blot and qRT-PCR analysis were performed to investigate effects on p53, Bax, Bcl-2, p38 MAPK, mTOR, PTEN, and Akt proteins and genes. The results indicated that quercetin, luteolin and combinations of these compounds with 5-FU inhibited the growth of HT 29 cells. Compared to the control, apoptosis were triggered 8.1 and 10.1 fold in HT-29 cells, that treated with quercetin + 5-FU and luteolin + 5-FU, respectively. VEGF amount significantly decreased by combined treatments. qRT-PCR and western blot results demonstrated that quercetin, luteolin and the combinations of these flavonoids with 5-FU, modulate the apoptotic pathways in HT-29 cells. The increase in p53, Bax, p38 MAPK, and PTEN gene expression levels compared to the control group was 1.71, 1.42, 3.26, and 3.29-fold with 5-FU + L treatment, respectively, while this increase was 8.43, 1.65, 3.55, and 3.54-fold with 5-FU + Q treatment, respectively. In addition, when the anti-apoptotic Bcl-2, mTOR, and Akt gene expression levels were normalized as 1 in the control group, they were 0.28, 0.41, and 0.22 with 5-FU + L treatment, and 0.32, 0.46, and 0.39, respectively, with 5-FU + Q treatment. These findings suggested that quercetin and luteolin synergistically enhanced the anticancer effect of 5-FU in HT 29 cells and may therefore minimize the toxic effects of 5-FU in the clinical treatment of colorectal cancer.

Clinical effects of intranasal corticosteroids on nasal symptoms in subjects with chronic rhinitis during COVID-19.

Background: The clinical effects of intranasal corticosteroids (INC) on nasal symptoms and the clinical course of coronavirus disease 2019 (COVID-19) in subjects with chronic rhinitis (CR) seem unclear. Objective: To evaluate the clinical effects of INCs on nasal symptoms in subjects with CR and with COVID-19. Methods: In subjects with CR and diagnosed with COVID-19 at four tertiary centers, quality of life and nasal symptoms were assessed by using the 22-item Sino-Nasal Outcome Test (SNOT-22) and the visual analog scale (VAS), respectively. In subjects with allergic rhinitis, nasal symptoms were also assessed on the total symptom score-6 (TSS-6) scale. The subjects were then allocated into two groups according to whether or not they used INCs while infected with the severe acute respiratory syndrome coronavirus 2 (group 1 and group 2, respectively). The subjects in group 2 were divided into two subgroups according to the use of antihistamines and/or leukotriene receptor antagonist or not (group 2a and group 2b, respectively). All the scores were compared before and during COVID-19 among the three groups. Results: A total of 71 subjects (21 in group 1, 24 in group 2a, and 26 in group 2b) were enrolled. The total scores of the SNOT-22 increased remarkably in all the groups during the infection when compared with the pre-COVID-19 scores (p < 0.001 in each group). However, the difference between the pre-COVID-19 and COVID-19 values revealed a lower decrease in the senses of smell and/or taste in group 1 than in group 2a and group 2b (p = 0.015, adjusted p = 0.045; and p = 0.001, adjusted p = 0.002, respectively). There were no significant differences in other COVID-19 findings, VAS, and TSS-6 scores among the groups (all p > 0.05). Conclusion: INCs in subjects with CR seemed protective against the decrease in smell and/or taste observed during COVID-19 and do not aggravate the clinical course of COVID-19.

Effectiveness of message framing in changing COVID-19 vaccination intentions: Moderating role of travel desire.

This research examines the effectiveness of message framing, message appeal and information content in changing respondents' COVID-19 vaccination intentions through influencing their vaccine risk perceptions. Furthermore, the moderating effect of travel desire on the relationship between vaccine risk perceptions and changing vaccination intentions is examined. In doing so, two rounds of data that were collected from the same respondents. The first survey recorded respondents' vaccination intentions, travel desire and socio demographics. A follow up survey tested cause-and-effect relationships on the proposed relationships using a 2 (message frame: gain, loss) x 2 (message appeal: rational, emotional) ×2 (information content: subjective, objective) between-subjects online experimental design. Findings suggest that loss-framed messages are more effective than gain-framed and emotional-rational messages in reducing risk perceptions and, thus, changing vaccination intentions. Travel desire is found to moderate the effect of vaccine risk perception on vaccination intentions by weakening the negative effect of vaccine risk perception on vaccination intention. Findings show the importance of travel desire along with message framing and message appeal on changing individuals' COVID-19 vaccination intentions in public health communications.

Impact of anxiety, stress and depression related to COVID-19 pandemic on the course of hereditary angioedema with C1-inhibitor deficiency.

BACKGROUND: Hereditary angioedema (HAE) attacks can be provoked with psychological factors. The aim of this study was to assess the effects of anxiety, depression and stress related to COVID-19 pandemic on disease activity of HAE patients during the quarantine period (QP) and the return to normal period (RTNP). METHODS: This study was conducted between March 2020 and September 2020 in four allergy centres. Demographic, clinical features and mental health status were evaluated in QP (from March to the beginning of June) and RTNP (from June to the beginning of September) applied by the government. The 10-point visual analogue scale (VAS10) was used to define the severity of HAE attacks. Depression, Anxiety and Stress Scales-21 (DASS-21) and Fear of COVID-19 (FC-19) scale were performed to assess mental health status. RESULTS: 139 HAE patients were included in the study. In QP, median attack numbers and median VAS10 scores were 5 (min-max: 0-45) and 6 (min-max: 0-10), respectively. HAE attack numbers, DASS-21 stress, anxiety, depression and total DASS-21 scores, and FC-19 scores were higher in QP than RTNP (p = 0.001, p < 0.001, p = 0.001, p < 0.001, p < 0.001, p < 0.001, respectively). However, there was no difference in attack severity scores between the two periods (p > 0.05). CONCLUSIONS: This study revealed that the restriction measures during COVID-19 outbreak cause an increase in the number of HAE attacks in relation to anxiety, depression, stress and fear of COVID-19 pandemic. Therefore, it is important to provide psychological support to HAE patients during the pandemic.

Pristine C60 Fullerene Nanoparticles Ameliorate Hyperglycemia-Induced Disturbances via Modulation of Apoptosis and Autophagy Flux.

Diabetes mellitus is a prevalent metabolic disorder associated with multiple complications including neuropathy, memory loss and cognitive decline. Despite a long history of studies on diabetic complications, there are no effective therapeutic strategies for neuroprotection in diabetes. Hyperglycemia-induced imbalance in programmed cell death could initiate a decline in neural tissue cells viability. Various nanomaterials can induce either cell death or cell survival dependent on the type and surface features. Pristine C60 fullerene is a nontoxic nanomaterial, which exhibits antioxidant and cytoprotective properties. However, the precise molecular mechanism with which the C60 nanoparticle exerts cytoprotective effect in diabetic subjects has not yet been fully addressed. Thus, this study aimed to determine whether C60 fullerene prevents oxidative stress impairment and to explore the effects of C60 fullerene on apoptosis and autophagy in diabetes mellitus to clarify its potential mechanisms. These effects have been examined for olive oil extracted C60 fullerene on the hippocampus of STZ diabetic rats. Up-regulation of Caspase-3, Beclin-1 and oxidative stress indexes and down-regulation of Bcl-2 were observed in the brain of STZ-diabetic rats. The exposure to C60 fullerene for a period of 12 weeks ameliorate redox imbalance, hyperglycemia-induced disturbances in apoptosis and autophagy flux via modulation of Caspase-3, Bcl-2, Beclin-1 and LC3I/II contents. Furthermore, C60 fullerene ameliorated the LC3I/II ratio and prevented extremely increased autophagy flux. Contrarily, pristine C60 fullerene had no modulatory effect on all studied apoptotic and autophagy markers in non-diabetic groups. Therefore, oil extracted C60 fullerene exhibits cytoprotective effect in hyperglycemia-stressed hippocampal cells. The presented results confirm that pristine C60 fullerene nanoparticles can protect hippocampal cells against hyperglycemic stress via anti-oxidant, anti-apoptotic effects and amelioration of autophagy flux. Moreover, C60 fullerene regulates a balance of autophagy via BCL-2/Beclin-1 reciprocal expression that could prevent functional disturbances in hippocampus.

Ellagic acid prevents kidney injury and oxidative damage via regulation of Nrf-2/NF-κB signaling in carbon tetrachloride induced rats.

Phytochemicals, bioactive food compounds, found in plants have been described as protective agents against renal injury. This work was planned to evaluate the effects of EA on anti-oxidative and anti-inflammation pathways in kidney damage induced with carbon tetrachloride. In this study, experimental animals (n = 36, 8 weeks old rats) were divided into 4 groups as follows: 1) Control group 2) EA group (10 mg/kg body weight) 3) CCl4 group (1.5 ml/kg, body weight) 4) EA + CCl4 group. The potentially protective effect of EA on kidney damage exposed by CCl4 in rats were evaluated. EA administration protects CCl4 induced kidney damage against oxidative stress through its antioxidant protection. Treatment of EA significantly reduced lipid peroxidation and improved glutathione and catalase enzyme activity. Recently studies showed that EA activated caspase-3 and nuclear transcription factor erythroid 2 related factor driven antioxidant signal pathway and protected the kidney against damage induced by oxidative stress. Furthermore, EA also markedly decreased the level of cyclooxygenase-2, the vascular endothelial growth factor and tumor necrosis factor-alpha and suppressed the protein synthesis of nuclear factor-kappa-B. This study reveals that EA has kidney protective effect against CCl4 induced oxidative damage and inflammation.

The Effect of TIGAR Knockdown on Apoptotic and Epithelial-Mesenchymal Markers Expression in Doxorubicin-Resistant Non-Small Cell Lung Cancer A549 Cell Lines.

Resistance to chemotherapeutic drugs is a critical problem in cancer therapy, but the underlying mechanism has not been fully elucidated. TP53-induced glycolysis regulatory phosphatase (TIGAR), an important glycolysis and apoptosis regulator, plays a crucial role in cancer cell survival by protecting cells against oxidative stress-induced apoptosis. In the present study, we investigated whether TIGAR is involved in epithelial-mesenchymal transition (EMT) in doxorubicin (DOX)-resistant human non-small cell lung cancer (NSCLC), A549/DOX cells. We found that the expression of TIGAR was significantly higher in A549/DOX cells than in the parent A549 cell lines. siRNA-mediated TIGAR knockdown reduced migration, viability and colony survival of doxorubicin-resistant lung cancer cells. Also, TIGAR knockdown decreased pro-survival protein Bcl-2 and increased pro-apoptotic Bax and cleaved poly (ADP-ribose) polymerase (PARP). Moreover, TIGAR depletion significantly up-regulated both caspase-3 and caspase-9 expression. Furthermore, TIGAR depletion up-regulated the expression of E-cadherin and down-regulated the expression of vimentin. These results indicate that TIGAR knockdown may inhibit EMT in doxorubicin (DOX)-resistant human NSCLC and may represent a therapeutic target for a non-small lung cancer cells chemoresistance.

Highly multiplexed single-cell analysis of formalin-fixed, paraffin-embedded cancer tissue.

Limitations on the number of unique protein and DNA molecules that can be characterized microscopically in a single tissue specimen impede advances in understanding the biological basis of health and disease. Here we present a multiplexed fluorescence microscopy method (MxIF) for quantitative, single-cell, and subcellular characterization of multiple analytes in formalin-fixed paraffin-embedded tissue. Chemical inactivation of fluorescent dyes after each image acquisition round allows reuse of common dyes in iterative staining and imaging cycles. The mild inactivation chemistry is compatible with total and phosphoprotein detection, as well as DNA FISH. Accurate computational registration of sequential images is achieved by aligning nuclear counterstain-derived fiducial points. Individual cells, plasma membrane, cytoplasm, nucleus, tumor, and stromal regions are segmented to achieve cellular and subcellular quantification of multiplexed targets. In a comparison of pathologist scoring of diaminobenzidine staining of serial sections and automated MxIF scoring of a single section, human epidermal growth factor receptor 2, estrogen receptor, p53, and androgen receptor staining by diaminobenzidine and MxIF methods yielded similar results. Single-cell staining patterns of 61 protein antigens by MxIF in 747 colorectal cancer subjects reveals extensive tumor heterogeneity, and cluster analysis of divergent signaling through ERK1/2, S6 kinase 1, and 4E binding protein 1 provides insights into the spatial organization of mechanistic target of rapamycin and MAPK signal transduction. Our results suggest MxIF should be broadly applicable to problems in the fields of basic biological research, drug discovery and development, and clinical diagnostics.

The Effect of Thymoquinone on the TNF-α/OTULIN/NF-κB Axis Against Cisplatin-Induced Testicular Tissue Damage.

One of the adverse effects of the antineoplastic drug cisplatin (CS) is damage to testicular tissue. This study aimed to examine the potential therapeutic effect of thymoquinone (TQ), a strong antioxidant, against testicular damage caused by CS. In the experiment, 28 rats were used, and the rats were randomly divided into four groups: control (n = 7), CS (n = 7), CS + TQ (n = 7), and TQ (n = 7). The experiment was called off after all treatments were finished on day 15. Blood serum and testicular tissues were utilized for biochemical, histological, immunohistochemical, mRNA expression, and gene protein investigations. The testosterone level decreased and oxidative stress, histopathological damage, dysregulation in mitochondrial dynamics, inflammation and apoptotic cells increased in testicular tissue due to CS administration. TQ supplementation showed anti-inflammatory, antioxidant, and anti-apoptotic effects in response to CS-induced testicular damage. In addition, TQ contributed to the reduction of CS-induced toxic effects by regulating the TNF-α/OTULIN/NF-κB pathway. TQ supplementation may be a potential therapeutic strategy against CS-induced testicular damage by regulating the TNF-α/OTULIN/NF-κB axis, inhibiting inflammation, oxidative stress, and apoptosis.

Loop Catalog: a comprehensive HiChIP database of human and mouse samples.

HiChIP enables cost-effective and high-resolution profiling of regulatory and structural loops. To leverage the increasing number of publicly available HiChIP datasets from diverse cell lines and primary cells, we developed the Loop Catalog (https://loopcatalog.lji.org), a web-based database featuring HiChIP loop calls for 1319 samples across 133 studies and 44 high-resolution Hi-C loop calls. We demonstrate its utility in interpreting fine-mapped GWAS variants (SNP-to-gene linking), in identifying enriched sequence motifs and motif pairs at loop anchors, and in network-level analysis of loops connecting regulatory elements (community detection). Our comprehensive catalog, spanning over 4M unique 5kb loops, along with the accompanying analysis modalities constitutes an important resource for studies in gene regulation and genome organization.

Eosinophilic lymph node abscesses following a COVID-19 vaccination: A case report.

In this paper, we reported a 37-year-old man who developed several lymphadenopathies after using the second dose of Pfizer-BioNtech vaccination against SARS-CoV-2. The excisional lymph node biopsy showed eosinophil-rich inflammation with micro-abscesses. Although eosinophilic dermatosis and eosinophilic myocarditis have been described previously following COVID-19 vaccinations, eosinophilic lymph node abscess was not reported in the literature. In our case, all lesions were completely recovered with steroid treatment. The patient has been doing well and no recurrence has been observed for six months.

Fullerene C60 reduces acute lung injury by suppressing oxidative stress-mediated DMBA-induced apoptosis and autophagy by regulation of cytochrome-C/caspase-3/beclin-1/IL-1α/HO-1/p53 signaling pathways in rats.

The objective of this study was to evaluate the effect of fullerene C60 nanoparticles against 7,12-dimethylbenz[a]anthracene (DMBA)-induced lung tissue damage in rats. 60 Wistar albino (8 weeks old) female rats were assigned into four groups: Control Group (C), Fullerene C60, DMBA, and Fullerene C60+DMBA. The rats in the DMBA and Fullerene C60+DMBA groups were administered DMBA (45 mg/kg bw, oral gavage). The rats in Fullerene C60, and Fullerene C60+DMBA groups were administered with Fullerene C60 (1.7 mg/kg bw, oral gavage). Expression levels of cytochrome-C, caspase-3, beclin-1, IL-1α, HO-1 and p53 proteins in lung tissue were determined by western blotting, lipid peroxidation malondialdehyde (MDA) analyzes, glutathione (GSH), glutathione peroxidase (GSH-Px), catalase activity (CAT) and total protein levels were determined by spectrophotometer. In addition, lung tissues were evaluated by histopathologically. Fullerene C60 reduced the increasing of MDA and IL-1α protein expression levels and attenuated histopathological changes in lung. Moreover, fullerene C60 enhanced the protein expression of cytochrome-C, caspase-3, beclin-1, HO-1, and p53, which were decreased in the DMBA group. Fullerene C60 has strong biological activity that it might be an effective approach for lung damage.
