Long non-coding RNA (LncRNA) CASC9/microRNA(miR)-590–3p/sine oculis homeobox 1 (SIX1)/NF-κB axis promotes proliferation and migration in breast cancer

ABSTRACT Long non-coding RNA (lncRNA)–microRNA–mRNA signaling axes have recently been shown to have a key role in the development of breast cancer (BC). In this study, we investigated how the cancer susceptibility candidate 9 (CASC9) gene affects the cell growth, invasion, migration, and apoptosis of BC cells. The levels of microRNA-590-3p (miR-590-3p), CASC9, and the sine oculis homeobox 1 (SIX1) gene were determined through qRT-PCR. We conducted cell counting kit-8 (CCK-8) assays to assess cell proliferation, transwell assays to detect cell migration/invasion, and flow cytometry to evaluate cell apoptosis. StarBase v2.0 was used to predict interactions between miR-590-3p and SIX1 or CASC9, and dual-luciferase reporter assays were used to verify these predictions. CASC9 protein was overexpressed in BC cells and tissues, while CASC9 knockdown inhibited BC cell growth, invasion, and migration and promoted apoptosis. Additionally, we verified that CASC9 competes for binding with miR-590-3p. Moreover, SIX1 was determined to be a target of miR-590–3p, and SIX1 expression was inhibited by miR-590-3p overexpression. CASC9 enhanced BC development by downregulating miR-590-3p and upregulating SIX1 during the activation of the NF-κB pathway. These data suggest that the CASC9/miR-590-3p/SIX1/NF-κB axis is involved in breast cancer progression, providing insight into the function of CASC9 in breast cancer development.
Screening and cellular validation of prognostic genes regulated by super enhancers in oral squamous cell carcinoma

ABSTRACT Oral squamous cell carcinoma (OSCC) is the leading cause of death in patients with head and neck cancer. Reliable biomarkers to guide treatment decisions for OSCC remain scarce. The purpose of this study was to identify novel prognostic markers regulated by super enhancers in OSCC. Eight modules were obtained by weighted gene co-expression network analysis (WGCNA), among which MEblue module had the highest correlation with tumor stage, alcohol consumption and smoking. There were 41 genes regulated by super enhancers in MEblue module. Functional analysis showed that 41 super enhancer-regulated genes were involved in cancer progression. A total of twenty transcription factors of the 41 genes were predicted. Prognostic analysis of the 41 genes and the top 5 transcription factors showed that patients with high expression of AHCY, KCMF1, MANBAL and TFDP1 had a poor prognosis. Immunohistochemical analysis showed that AHCY, KCMF1 and MANBAL were highly expressed in OSCC tissue. Cellular experiment demonstrated that TFDP1 promoted AHCY, KCMF1 and MANBAL expression by binding to the super enhancers of these genes. Knockdown of TFDP1, AHCY, KCMF1 and MANBAL inhibited the proliferation of OSCC cells. In conclusion, AHCY, KCMF1 and MANBAL were recognized as super enhancer-regulated prognostic biomarkers regulated by TFDP1 in OSCC.
Reliability and Minimal Detectable Change of Sprint Times and Force-Velocity-Power Characteristics

Abstract Edwards, T, Banyard, HG, Piggott, B, Haff, GG, and Joyce, C. The reliability and minimal detectable change of sprint times and force-velocity-power characteristics. J Strength Cond Res 36(1): 268–272, 2022—Research has not yet provided critical information for practitioners to determine the minimal detectable change (MDC) in sprint times or force-velocity-power characteristics. Therefore, the aim of this study was to establish the interday reliability and MDC of sprint times and sprint force-velocity-power characteristics in junior Australian football (AF) players. Seventeen players were assessed using a radar device that recorded instantaneous velocity during 3 maximal 30-m sprint accelerations performed on 2 nonconsecutive days. Sprint force, velocity, and power characteristics were derived through inverse dynamics applied to the raw velocity-time data. Relative and absolute reliability was determined by calculating the intraclass correlation coefficient (ICC), coefficient of variation (CV), and MDC. Data analysis was assessed for (a) the first trial, (b) the best trial (the fastest 30-m split time), (c) the average of the first 2 trials, and (d) the average of all 3 trials from each testing session. The main findings were (a) absolute theoretical maximum force (F0), theoretical maximal velocity (V0), absolute and relative maximum power (Pmax), maximum ratio of force (RFmax), maximum velocity (Vmax), and all sprint distance times (5–30 m) displayed acceptable reliability (CV < 10% and ICC >0.75) and 2) the average of 2 and 3 trials was the best method of establishing reliable sprint times and force-velocity-power characteristics between sessions. This study provides important information for practitioners to determine the MDC in sprint times and force-velocity-power characteristics that allow coaches to identify true changes in performance.
Comparing self-reported vs. parent/caregiver reported levels of social participation for young adults with intellectual disabilities: A pilot study

Background: This study focused on the level of satisfaction of social participation reported by young adults with intellectual disabilities, and the comparison of these levels to those reported by their caregivers. Methods: Fifteen young adults with intellectual disabilities and their parents/caregivers completed the Patient-Reported Outcomes Measurement Information System Satisfaction with Participation in Discretionary Social Activities–Calibrated Items (PROMIS SF–Social Sat DSA) and the Satisfaction with Social Roles and Activities–Short Form (Neuro-QoL SF). Results: Reports from these young adults were compatible to that of the general population. There was general agreement on the Social Sat DSA between the individuals and their caregivers, but there were differences between groups on the Neuro-QoL SF, with the caregivers typically giving higher scores (p = .025). Conclusion: This pilot study demonstrates the importance of involving both the individuals with intellectual disabilities, and their parents/caregivers when conducting survey research. Further research is encouraged.
Prevalence of bleeding symptoms among young adults in Saudi Arabia, a national survey

Supplemental Digital Content is available in the text Abstract Prevalence of bleeding disorders vary due to several factors including geographical location. Mild bleeding disorders can lead to iron deficiency, morbidity, and in severe cases mortality. Quantification of haemorrhagic symptoms is a key component in management of bleeding disorders and a challenging task for clinicians. An abridged version of MCMDM-1vWD questionnaire with validated Arabic translation was used to quantify bleeding disorders in adult students (n = 1138) in 4 different regions of Kingdom of Saudi Arabia. Statistical analysis was performed to indicate gender disparity and prevalence. 74.5% of respondents answered at least 1 question with affirmation, with 32.3% affected in Riyadh showing the highest prevalence and 14.03% affected in Dammam showing the least prevalence (P-value < .001). Gender-wise, higher prevalence of bleeding disorders in females 54.9% than in males 45.1% was observed (P-value .01). Epistaxis prevalence was significantly higher in males 30.7% vs 23.2% in females (P-value .0004), while cutaneous symptoms were reported significantly more by female participants 29.7% vs 12.3% in males (P-value < .001). Menorrhagia was reported by 28% of females, with heavy bleeding experienced by 57.6% female participants for <7 days while in 42.4% of females for >7 days. The current study signifies the ethnic distribution and gender disparity of mild bleeding disorders, and highlights the need for national surveillance system in order to improve management of patients with bleeding disorders.
Population pharmacokinetic–pharmacodynamic modeling of PB2452, a monoclonal antibody fragment being developed as a ticagrelor reversal agent, in healthy volunteers

PB2452, a neutralizing monoclonal antibody fragment that binds the antiplatelet drug ticagrelor with high affinity, is being developed as a ticagrelor reversal agent. To identify a clinically useful intravenous (i.v.) reversal regimen, a semimechanistic exposure‐response model was developed during the PB2452 first‐in‐human phase I study. From a randomized, double‐blind, placebo‐controlled, single‐dose trial to evaluate the safety, efficacy, and pharmacokinetics (PKs) of PB2452 in 61 healthy volunteers pretreated with ticagrelor, sequential dose cohort data were used to build and refine an exposure‐response model that combined population PK models for ticagrelor (TICA), ticagrelor active metabolite (TAM), and PB2452, and related their binding relationships to the PK of uncomplexed TICA and TAM which is predictive of platelet inhibition. Platelet function was assessed by multiple assays. The model was developed using Bayesian methods in NONMEM. Human PK and pharmacodynamic data from sequential dose cohorts were used to initially define and then refine model parameters. Model simulations indicated that an initial i.v. bolus of PB2452, followed by a high‐rate infusion, and then a slower‐rate infusion would provide immediate and sustained reversal of the antiplatelet effects of ticagrelor. Based on model predictions, a 6 g i.v. bolus followed by 6 g infused over 4 h and then 6 g over 12 h was identified and tested in study subjects and shown to provide complete reversal within 5 min of infusion onset that was sustained for 20–24 h. The model is predictive of the reversal profile of PB2452 and will inform future trials of PB2452.
Supramolecular Aggregation-Induced Emission Gels Based on Pillar[5]arene for Ultrasensitive Detection and Separation of Multianalytes

A novel supramolecular AIE (aggregation-induced emission) gel (PMDP-G) based on pillar[5]arene which could ultrasensitively detect and separate multianalytes was efficiently constructed. First, a novel supramolecular gelator, PM (host), and a functionalized pillar[5]arene, DP (guest), were successfully designed and synthesized. Then, host PM and guest DP could construct a stable supramolecular AIE gel, PMDP-G, via “exo-wall” π–π interactions and host–guest interactions in cyclohexanol solution. Interestingly, PMDP-G shows bright blue-white AIE and the fluorescence quantum yield is about 60%. Moreover, PMDP-G could carry out ultrasensitive detection and separation of multianalytes such as Fe3+, Hg2+, Ag+, F–, and Br– by the competition between “exo-wall” π–π interactions and cation−π interactions. The LODs (limits of lowest detection) of these AIE gels for Fe3+, Hg2+, Ag+, F–, and Br– are in the range of 7.3 × 10–10–9.5 × 10–9 M, indicating high sensitivity. More importantly, the xerogel of PMDP-G could ad.
Role of Maspin, CK17 and Ki-67 Immunophenotyping in Diagnosing of Pancreatic Ductal Adenocarcinoma in Endoscopic Ultrasound-Guided Fine Needle Aspiration Cytology

Background and study aim: One of the problems in diagnosing pancreatic ductal adenocarcinoma (PDAC) is differentiation between PDAC cells and benign pancreatic tissue cells in cytologic samples. This study aimed to evaluate the usefulness of Maspin, CK17 and Ki-67 immunocytochemistry (ICC) in differentiation between these two groups of cells. Materials and methods: This retrospective study was carried on 80 cases of PDAC and 25 cell blocks of benign pancreatic tissue cells as a control group for evaluation of Maspin, CK17 and Ki-67 ICC. PDAC cases were sampled by endoscopic ultrasound guided fine needle aspiration cytology (EUS-FNAC), while cell blocks of control group were aspirated from benign pancreatic tissues that were obtained from the pancreatic surgically resected specimens. Immunostaining patterns, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of each antibody as well as possible antibody combined panels of these markers in differentiation between the two groups were evaluated. Results: Positive immunoreactivity for Maspin, CK17 and Ki-67 were 92.5%, 80% and 72.5% in PDAC cases, respectively. In contrast to PDAC cases, all the cell blocks of benign pancreatic tissue cells were negative for these markers. Regarding different panels, combined use of Maspin, CK17 and Ki-67 together as a triple test (at least one of them is positive) achieved the highest sensitivity of 98.8%, specificity of 100%, PPV of 100%, NPV of 96.2% and accuracy of 99% in the differentiation between PDAC and benign pancreatic tissue. Conclusion: Employing this short panel [Maspin, CK17 and Ki-67] is helpful for better differentiation between PDAC and benign pancreatic tissue.
Modulation of dopamine release by ethanol is mediated by atypical GABAA receptors on cholinergic interneurons in the nucleus accumbens

Previous studies indicate that moderate‐to‐high ethanol (EtOH) concentrations enhance dopamine (DA) neurotransmission in the mesolimbic DA system from the ventral tegmental area (VTA) and projecting to the nucleus accumbens core (NAc). However, voltammetry studies demonstrate that moderate‐to‐high EtOH concentrations decrease evoked DA release at NAc terminals. The involvement of γ‐aminobutyric acid (GABA) receptors (GABAARs), glycine (GLY) receptors (GLYRs) and cholinergic interneurons (CINs) in mediating EtOH inhibition of evoked NAc DA release were examined. Fast scan cyclic voltammetry, electrophysiology, optogenetics and immunohistochemistry techniques were used to evaluate the effects of acute and chronic EtOH exposure on DA release and CIN activity in C57/BL6, CD‐1, transgenic mice and δ‐subunit knockout (KO) mice (δ−/−). Ethanol decreased DA release in mice with an IC50 of 80 mM ex vivo and 2.0 g/kg in vivo. GABA and GLY decreased evoked DA release at 1–10 mM. Typical GABAAR agonists inhibited DA release at high concentrations. Typical GABAAR antagonists had minimal effects on EtOH inhibition of evoked DA release. However, EtOH inhibition of DA release was blocked by the α4β3δ GABAAR antagonist Ro15‐4513, the GLYR antagonist strychnine and by the GABA ρ1 (Rho‐1) antagonist TPMPA (10 μM) and reduced significantly in GABAAR δ−/− mice. Rho‐1 expression was observed in CINs. Ethanol inhibited GABAergic synaptic input to CINs from the VTA and enhanced firing rate, both of which were blocked by TPMPA. Results herein suggest that EtOH inhibition of DA release in the NAc is modulated by GLYRs and atypical GABAARs on CINs containing δ‐ and Rho‐subunits.
Icariin inhibits the expression of IL-1β, IL-6 and TNF-α induced by OGD/R through the IRE1/XBP1s pathway in microglia

Abstract Context Icariin (ICA), a flavonol glycoside extracted from Epimedium brevicornum Maxim (Berberidaceae), has been proven to inhibit inflammatory response in ischaemic rats in our laboratory's previous work. However, its underlying mechanism is still unclear. Objective This study investigates the effects of ICA on endoplasmic reticulum (ER) stress mediated inflammation induced by cerebral ischaemia–reperfusion (I/R) injury in vitro. Materials and methods The primary cultured microglia were treated with oxygen-glucose deprivation (OGD) for 2 h followed by a 24 h reoxygenation. ICA (0.37, 0.74 and 1.48 μmol/L) administration was performed 1 h prior OGD and acting through 2 h OGD. The control group was cultured in normal conditions. At 24 h after reoxygenation, the expression of IRE1α, XBP1u, XBP1s, NLRP3 and caspase-1 was detected by western blotting (WB) and quantitative real-time (qRT) PCR; the expression of p-IRE1α was examined by WB; the expression of IL-1β, IL-6 and TNF-α was measured by WB and enzyme-linked immunosorbent assay (ELISA). Results ICA (0.37, 0.74 and 1.48 μmol/L) reduced the ratio of p-IRE1α/IRE1α, the mRNA level of IRE1α, the expression of XBP1u, XBP1s, NLRP3, caspase-1 at both the mRNA and protein level expression of IL-1β, IL-6 and TNF-α in OGD/R injured microglia. Overexpression of IRE1 significantly reversed the effects of ICA. Discussion and conclusions These results suggested that ICA might decrease the expression of IL-1β, IL-6 and TNF-α by inhibiting IRE1/XBP1s pathway. The anti-inflammatory effect of ICA may provide a potential therapeutic strategy for the treatment of brain injury after stroke.
A Systematic Review of Feeding Interventions for Infants with Cleft Palate

Objective Various devices and techniques have been proposed to reduce feeding difficulties experienced by infants with cleft palate. The aim of this review is to identify and assess the scope and quality of evidence for these interventions. Methods A systematic review of published literature evaluating feeding interventions for infants with cleft palate (with or without cleft lip) from database inception to 2021 was conducted using Preferred Reporting Items for Systematic Reviews guidelines. Quality appraisal of included studies was conducted using a methodological index for nonrandomized studies, Cochrane, or a measurement tool to assess systematic reviews 2 instruments, according to study type. Results Fourteen studies met inclusion criteria, with the majority (71%) of studies consisting of second-level evidence. Included interventions were specialty bottles (21%), alternative feeding delivery systems (14%), obturators (14%), and educational programs (14%). Specialty bottles and palatal obturators did not appear to offer any substantial growth advantages compared to traditional bottles or no intervention, respectively. Designated education programs for the mothers of infants with clefts had a positive impact on infant growth. Conclusions Overall evidence evaluating feeding interventions for infants with cleft palate was moderate to low. While it does not appear that specialized feeding delivery systems or palatal obturators significantly improve growth in infants with clefts compared to children without cleft conditions, education programs do appear to be beneficial.
Adjunctive benefits of systemic metronidazole on non-surgical treatment of peri-implantitis. A randomized placebo-controlled clinical trial.

AIM To study clinical, radiographic, and microbiological outcomes after non-surgical therapy of peri-implantitis with or without adjunctive systemic metronidazole. MATERIALS AND METHODS A randomized placebo-controlled clinical trial was carried out in 32 subjects (62 implants) diagnosed with peri-implantitis. Implants received a mechanical non-surgical debridement session and systemic metronidazole or placebo. Clinical, radiographic, and microbiological outcomes were evaluated at baseline, 3, 6, and 12 months. RESULTS After 12 months, the test treatment resulted in significantly greater PPD reduction (2.53 vs. 1.02 mm) and CAL gain (2.14 vs. 0.53 mm) (p value <.05) in comparison with placebo. The test treatment also resulted in additional radiographic bone gain (2.33 vs. 1.13 mm) compared with placebo (p value <.05). There was a significantly greater decrease in Porphyromonas gingivalis, Tannerella forsythia, and Campylobacter rectus counts compared with the control group (p value <.05). At the end of follow-up, 56.3% of patients met the success criteria in the test group and 25% in the control group. CONCLUSIONS The use of systemic metronidazole as an adjunct to non-surgical treatment of peri-implantitis resulted in significant additional improvements in clinical, radiographic, and microbiological parameters after 12 months of follow-up. This study is registered in ClinicalTrials.gov (NCT03564301).
Role of typical elements in 
Nd2Fe14X
 (
X=B
, C, N, O, F)

The magnetic properties and structural stability of Nd$_{2}$Fe$_{14}X$ ($X$ = B, C, N, O, F) are theoretically studied by first-principles calculations focusing on the role of $X$. We find that B reduces the magnetic moment (per formula unit) and magnetization (per volume) in Nd$_{2}$Fe$_{14}$B. The crystal-field parameter $A_2^0 \langle r^2 \rangle$ of Nd is not enhanced either, suggesting that B has minor roles in the uniaxial magnetocrystalline anisotropy of Nd. These findings are in contrast to the long-held belief that B works positively for the magnetic properties of Nd$_{2}$Fe$_{14}$B. As $X$ changes from B to C, N, O and F, both the magnetic properties and stability vary significantly. The formation energies of Nd$_{2}$Fe$_{14}X$ and $\alpha$-Fe relative to that of Nd$_{2}$Fe$_{17}X$ are negative for $X$ = B and C, whereas they are positive when $X$ = N, O and F. This indicates that B plays an important role in stabilizing the Nd$_{2}$Fe$_{14}$B phase.
Telemedicine and visit completion among people with HIV during the coronavirus disease 2019 pandemic compared with prepandemic

Supplemental Digital Content is available in the text Objectives: Telemedicine became the primary mode of delivering care during the COVID-19 pandemic. We describe the impact of telemedicine on access to care for people with HIV (PWH) by comparing the proportion of PWH engaged in care prior to and during the COVID-19 pandemic. Design and methods: We conducted an observational analysis of patients enrolled in the Johns Hopkins HIV Clinical Cohort, a single-center cohort of patients at an urban HIV subspecialty clinic affiliated with an academic center. Due to the COVID-19 pandemic, the clinic transitioned from in-person to mostly telemedicine visits. We compared patients receiving care in two time periods. The prepandemic period included 2010 people with at least one visit scheduled between 1 September 2019 and 15 March 2020. The pandemic period included 1929 people with at least one visit scheduled between 16 March 2020 and 30 September 2020. We determined the proportion of patients completing at least one of their scheduled visits during each period. Results: Visit completion increased significantly from 88% prepandemic to 91% during the pandemic (P = 0.008). Visit completion improved significantly for patients age 20–39 (82 to 92%, P < 0.001), women (86 to 93%, P < 0.001), Black patients (88 to 91%, P = 0.002) and patients with detectable viremia (77 to 85%, P = 0.06) during the pandemic. Only 29% of people who completed at least one telemedicine visit during the pandemic did so as a video (versus telephone) visit. Conclusion: During the pandemic when care was widely delivered via telemedicine, visit completion improved among groups with lower prepandemic engagement but most were limited to telephone visits.
LYVE1+ macrophages of murine peritoneal mesothelium promote omentum-independent ovarian tumor growth

Zhang, Kim, and colleagues reveal two macrophage subpopulations lining peritoneal surfaces that are distinct from peritoneal fluid macrophages. One population expresses LYVE1, resembles omental macrophages, and promotes expansion of ovarian cancer within the cavity in the absence of the omentum.
