The voltage-dependent anion channel 1 (VDAC1) forms an oligomeric structure on the mitochondrial outer membrane, which plays critical roles in many physiological processes. Research studies have demonstrated that the knockout of VDAC1 increases pigment content and up-regulates the expression of melanogenic genes. Due to its involvement in various physiological processes, the depletion of VDAC1 has significant detrimental effects on cellular functions and the inhibition of VDAC1 oligomerization has recently emerged as a promising strategy for the treatment of several diseases. In this study, we found that VDAC1 oligomerization inhibitors, VBIT-12 and NSC-15364, promote melanogenesis, dendrite formation and melanosome transport in human epidermal melanocytes (HEMCs). Mechanistically, treatment of HEMCs with an oligomerization inhibitor increased the level of cytoplasmic calcium ions, which activated calcium-calmodulin dependent protein kinase (CaMK) and led to the phosphorylation of CREB and the nuclear translocation of CREB-regulated transcription coactivators (CRTCs). Subsequently, CRTCs, p-CREB and CREB-binding protein (CBP) in the nucleus cooperatively recruit the transcription machinery to initiate the transcription of MITF thus promoting pigmentation. Importantly, our study also demonstrates that VDAC1 oligomerization inhibitors increase pigmentation in zebrafish and in human skin explants, highlighting their potential as a therapeutic strategy for skin pigmentation disorders.
PURPOSE:To provide a new 3-butenoic acid derivative exhibiting excellent antithrombotic action by oral administration as well as parenteral administration, useful as an antithrombotic agent and also as an intermediate for other antithrombotic agent having excellent antithrombotic action. CONSTITUTION:The 3-butenoic acid derivative expressed by formula I [ring A is tri(lower alkoxy)phenyl; one of R<1> and R<2> is alkoxy and the other is NH2), e.g. (E)-2-[(E)-3,4,5-trimethoxybenzylidene]-3-carbamoyl-4-phenyl-3-butenoic ac id methyl ester. The compound can be produced by reacting a new compound of formula II (one of R<11> and R<12> is lower alkoxy and the other is OH), its salt or its reactive derivative with ammonia. A compound of formula III having excellent antithrombotic action can be produced by the intramolecular cyclization of the objective compound. The new compound of formula II used as a starting compound can be produced from benzaldehyde or a tri(lower alkoxy)benzaldehyde and a succinic acid di(lower alkyl) ester with three steps.
This single center, randomized, sham-controlled, participant-blinded and assessor-blinded trial will be conducted at the inpatient ward of cardiothoracic surgery department of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine. The trial will commence after ethical approval has been obtained and the protocol has been registered. Patient enrollment started in late June 2021 and is expected to end in March 2023. An estimated 92 participants will be recruited and randomly assigned to receive TEAS or sham TEAS (STEAS) in a l:l ratio using SPSS 21.0 software. During the development of the standard protocol, the Standards for Reporting Interventions in Clinical Trials for Acupuncture (STRICTA) and the SPIRIT reporting guidelines will be followed to explicitly and transparently explain the therapeutic processes involved.

Patients who will undergo VATS for pulmonary nodules will be screened. . Potential subjects will be interviewed preoperatively by the clinical research coordinator to assess whether they meet the inclusion and exclusion criteria. Eligible participants will voluntarily provide written informed consent prior to randomization.

This study will have a single-blind design. The patients are blinded to the group assignment and are told that they might or might not feel a sensation when the TEAS is working. Both acupoint stimulations in the TEAS group and in the STEAS group will be performed by the same acupuncturist who is not involved in the process of data collection. The TEAS instrument is covered with an opaque box for adequate blinding. The randomized numbers were generated with SPSS 21.0 (IBM®SPSS®Statistics, Version 21) software. The random sequence for group classification will be sealed in a confidential envelope. Patients will be randomly allocated into the TEAS group or STEAS group at a ratio of 1:1. Group assignment was exposed from a sealed envelope only by an acupuncturist. Patients will be treated separately to prevent communication. Efficacy evaluation will be conducted blinded to the grouping allocation. The efficacy evaluators and statisticians will be separated and blinded. To test the participant-blinding effects, all participants will be asked to guess whether they had received TEAS or STEAS within 5 minutes after one of the treatment sessions before VATS.
UNLABELLED: The extent to which non-genetic environmental factors, such as diet, contribute to carcinogenesis has been long debated. One potential mechanism for the effects of environmental factors is through epigenetic modifications that affect gene expression without changing the underlying DNA sequence. However, the functional cooperation between dietary factors and cancer-causing epigenetic regulation is largely unknown. Here, we use a mouse model of age-dependent p16 epimutation, in which the p16 gene activity is directly controlled by promoter DNA methylation. We show p16 epimutation is modulated by folate and cofactors in dietary supplementation, which leads to increased colon cancer risk. Importantly, our findings provide functional evidence concerning the safety of folate fortification in the general population.
SIGNIFICANCE: Our study demonstrates that dietary folate and cofactors modulate tumor-suppressor gene methylation to increase intestinal tumorigenesis. Our findings highlight the need for monitoring the long-term safety of folate fortification in high-risk individuals.
Methods, systems and apparatuses, including computer programs encoded on computer storage media, are provided for assisting users with adherence to a medication regimen. An attachable device includes a sensor module releasably attached to an adapter, which is in turn attached to a medication container using a connector. The sensor module can be removed from the adapter to change an included battery without removing the adapter from the medication container. The sensor module is in communication with a user device, such as a smart phone. A user can use an app on the user device to create a medicine regimen, or schedule, and send the schedule to the sensor module. The user can also set notification preferences on the user device to be sent to the sensor module. The sensor module includes audio and/or visual transducers that notify the user to take the medication at the scheduled times. The sensor module further includes one or more buttons that are pressed when a user opens the medication container. The button(s) are configured so the action of the user required to open the container also presses at least one button. The sensor module records the actions of the user, including when the medication container is opened, when a dose of the medication is missed, and when the user presses a mood indication button. The user actions can be transmitted to the user device, which can then transmit the recorded actions to a server. The sensor module may be configured to attempt communication with the user device on a periodic basis to conserve battery life.
Metallosis is an unusual but consequential complication arising from orthopedic hardware implantation, characterized by the deposition of metallic particles in the periprosthetic soft tissues. The incidence of metallosis associated with shoulder arthroplasties is exceptionally rare since the shoulder is not a weight-bearing joint, making it less susceptible to mechanical wear and, consequently, to conditions like particle disease and metallosis. Nevertheless, anomalous metal-on-metal interactions can develop in total shoulder arthroplasties if the polyethylene component fails due to wear, fracture, or dissociation. If left unaddressed, metallosis can incite an adverse immune-mediated local tissue response, culminating in joint destruction and adjacent soft tissues and muscle necrosis. In this case report, the diagnosis of metallosis was made in a patient with an anatomic total shoulder arthroplasty using a state-of-the-art photon counting detector CT supplemented by post-processing metal artifact reduction algorithms. This advanced imaging approach was effective in discerning the source of implant failure and in identifying manifestations of severe metallosis including osteolysis and pseudotumor formation. Advanced imaging methods can accurately characterize the severity and extent of metallosis, thereby helping guide surgical planning to mitigate serious complications associated with this condition.
OBJECTIVE: The current study aimed to investigate the characteristics of tumor-associated macrophages (TAMs) and their association with microvascular density (MVD) in tumor progression in different grades of orofacial squamous cell carcinoma (OSCC) in the Pakistani population.
STUDY DESIGN: This prospective study included 234 patients with oral cancer reported at different hospitals in Pakistan diagnosed with OSCC. Tumors were graded on the Anneroth grading system and the association between the frequency of TAMs and MVD was examined in vivo. The macrophages visible through immunohistochemistry for CD68 and the microvessels observed through immunohistochemistry for CD34 were manually counted in 3 high-power fields.
RESULTS: The CD68 and CD34 counts were significantly lower in well-differentiated squamous cell carcinoma compared to poorly differentiated squamous cell carcinoma. Linear regression analysis revealed a positive correlation between the area percentage of CD68 immunoreactivity and the grade of the tumor (r = 0.776). Vice versa, a positive correlation also existed between the area percentage of CD34 immunoreactivity and the grade of the tumor (r = 0.690). Pearson correlation revealed a positive association between the TAMs and MVD (r = 0.680; P < .001).
CONCLUSIONS: There was an increased population of tumor-associated macrophages and tumor angiogenesis with the increasing grade of orofacial squamous cell carcinoma. (Oral Surg Oral Med Oral Pathol Oral Radiol YEAR;VOL:page range).
BACKGROUND: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are associated with high mortality, morbidity, and poor quality of life and constitute a substantial burden to patients and health care systems. New approaches to prevent or reduce the severity of AECOPD are urgently needed. Internationally, this has prompted increased interest in the potential of remote patient monitoring (RPM) and digital medicine. RPM refers to the direct transmission of patient-reported outcomes, physiological, and functional data, including heart rate, weight, blood pressure, oxygen saturation, physical activity, and lung function (spirometry), directly to health care professionals through automation, web-based data entry, or phone-based data entry. Machine learning has the potential to enhance RPM in chronic obstructive pulmonary disease by increasing the accuracy and precision of AECOPD prediction systems.
OBJECTIVE: This study aimed to conduct a dual systematic review. The first review focuses on randomized controlled trials where RPM was used as an intervention to treat or improve AECOPD. The second review examines studies that combined machine learning with RPM to predict AECOPD. We review the evidence and concepts behind RPM and machine learning and discuss the strengths, limitations, and clinical use of available systems. We have generated a list of recommendations needed to deliver patient and health care system benefits.
METHODS: A comprehensive search strategy, encompassing the Scopus and Web of Science databases, was used to identify relevant studies. A total of 2 independent reviewers (HMGG and CM) conducted study selection, data extraction, and quality assessment, with discrepancies resolved through consensus. Data synthesis involved evidence assessment using a Critical Appraisal Skills Programme checklist and a narrative synthesis. Reporting followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.
RESULTS: These narrative syntheses suggest that 57% (16/28) of the randomized controlled trials for RPM interventions fail to achieve the required level of evidence for better outcomes in AECOPD. However, the integration of machine learning into RPM demonstrates promise for increasing the predictive accuracy of AECOPD and, therefore, early intervention.
CONCLUSIONS: This review suggests a transition toward the integration of machine learning into RPM for predicting AECOPD. We discuss particular RPM indices that have the potential to improve AECOPD prediction and highlight research gaps concerning patient factors and the maintained adoption of RPM. Furthermore, we emphasize the importance of a more comprehensive examination of patient and health care burdens associated with RPM, along with the development of practical solutions.
Environmental heat stress represents a pervasive threat to warfighters, athletes, and occupational workers, impacting performance and increasing the risk of injury. Exertional heat illness (EHI) is a spectrum of clinical disorders of increasing severity. While frequently predictable, EHI can occur unexpectedly and may be followed by long-term comorbidities, including cardiovascular dysfunction and exercise intolerance. The objective of this study was to assess genetic factors contributing to EHI. Whole-exome sequencing was performed in a cohort of 53 cases diagnosed with EHI. Rare variants in prioritized gene sets were analyzed and classified per published guidelines. Clinically significant pathogenic and potentially pathogenic variants were identified in 30.2% of the study cohort. Variants were found in 14 genes, including the previously known RYR1 and ACADVL genes and 12 other genes (CAPN3, MYH7, PFKM, RYR2, TRPM4, and genes for mitochondrial disorders) reported here for the first time in EHI. Supporting structural and functional studies of the TRPM4 p.Arg905Trp variant show that it impairs the thermal sensitivity of the TRPM4 channel, revealing a potentially new molecular mechanism contributing to EHI susceptibility. Our study demonstrates associations between EHI and genes implicated in muscle disorders, cardiomyopathies, thermoregulation, and oxidative phosphorylation deficiencies. These results expand the genetic heterogeneity of EHI and shed light on its molecular pathogenesis.
Very few human data are currently available on the fatty acid composition of cardiomyocytes membranes. Preoperative omega-3 supplementation for patients undergoing cardiac surgery with cardiopulmonary bypass is correlated with a decreased frequency of postoperative complications in type of arrhythmia atrial fibrillation. Atrial fibrillation is the most common complication: 30 to 50% after myocardial revascularization. The occurrence of atrial fibrillation increases morbidity and mortality after surgery for sure. The pathophysiological mechanisms of common atrial fibrillation treated in heart rhythm units are different from those of postoperative atrial fibrillation. Indeed, atrial fibrillation is a common disease primarily of the left atrium, although atrial fibrillation after cardiac surgery is a multifactorial disease with implication of various pathogens such as inflammation without precise anatomical support. The preventive use of polyunsaturated fatty acids omega-3 long-chain (LC-AGPIω3), prior cardiac surgery is far from widespread due to a Lack of information dissemination, by insufficient number of published studies, despite the existence of a number of ongoing clinical trials and a complete ignorance of biological mechanisms of action. A human clinical study is needed. In a context of cardiac surgery with cardiopulmonary bypass and without deleterious side effects of preoperative enrichment in omega-3, it seems appropriate to conduct a feasibility study to provide information on structural changes in membranes of cardiomyocytes.
Porphyrins containing one or more negatively-charged, amphiphilic nido-carborane substituents have antiviral or virucidal activity. The most active compounds tested to date are negatively charged, amphiphilic, and water-soluble. The negative charges lie primarily in the boron clusters. The carbon-carbon bonds linking the boron-containing groups to the porphyrin ring make the compounds highly resistant to hydrolysis. These compounds have strong potential for use as antiviral and virucidal drugs, as they are highly stable, water-soluble, negatively-charged, amphiphilic, and have low toxicity to normal mammalian cells. Preliminary tests in vitro have shown high activity against HIV.
The conservative treatment for Kohler's disease will take several months, but some patients still have flatfoot and persistent pain. From October 2013 to July 2015, 3 children with Kohler's disease underwent navicular decompression and micro-circulation reconstruction surgery in our hospital. All the patients have received conservative treatment for more than 3 months and the effect was poor. X-ray showed the bone density of navicular increased significantly. All patients were followed up over 1 year. The 3 patients recovered well. VAS score decreased from 7.0 to 2.6 at 1 month after the operation. The pain symptom disappeared completely on 3 months after surgery. The density of navicular bone recovered to normal. Navicular decompression and micro-circulation reconstruction surgery may quickly improve the ischemic status of navicular bone, alleviate pain symptom and enable patients to resume normal activity as soon as possible.
The state of Virginia, including the Virginia Department of Health and three academic medical centers and one federally qualified health center, plans a two-phase demonstration, first of improvement in the percentage of adults with SCD who are in SCD specialty care (Phase I), then of improvement in adherence to HU of eligible SCD adults (Phase II). Both phases will use existing academic SCD providers, and an innovative, multimodal strategy, featuring specially trained SCD patient navigators (PNs), that addresses barriers to care and to HU use. In Phase I we will demonstrate the feasibility of utilizing PNs to overcome patient access barriers to SCD care. In Phase II we will test the efficacy of PNs for overcoming barriers to acceptance of and adherence with HU therapy. Patients will be randomized to a PN arm or to a usual care arm. Providers will implement NIH guidelines for HU eligibility and prescribing in both arms. All HU eligible patients will be offered HU at each clinical visit. Among patients prescribed HU, if a maximum tolerated dose (MTD, defined in end points) has not been reached, providers will dose escalate every 8-12 weeks to MTD, rather than to clinical effect, before declaring treatment success or failure.

This project will be critically important and impactful by demonstrating the feasibility of a statewide community-based strategy to assist vulnerable SCD adults in obtaining SCD specialty care and likely prolonging life, a model that other states could adopt.
Eligible HCC patients visiting the outpatient clinics of LCCH at the study sites at NCT Heidelberg and University Medical Center Mannheim will be enrolled into the study after informed consent. Patients undergo 2:1 randomization into either the FMT or placebo group. Study lead in with a first sonographically guided tumor biopsy, if not already performed for diagnostic purposes, and a sigmoidoscopy will be scheduled within 10 days after study enrollment in an outpatient setting. Start of active pharmacotherapy with A/B will begin within five working days after sigmoidoscopy. A/B administration will be administered as standard of care every 21 days. At day -3 to 0 oral Vancomycin will be given 4x 250mg to the verum group. At day 0 and 21, concurrent to the first and second cycle of A/B, encapsulated FMT will be administered on the same day. At day 40-42, before the third cycle of A/B, a second biopsy of the liver lesion and a sigmoidoscopy will be performed. Clinical efficacy and safety will be assessed as indicated per protocol analysis.
PURPOSE:To obtain the objective protein by treating a liquid containing various proteins and obtained by the extraction of the brain of mammals with a specific water-insoluble carrier, collecting the adsorbed or unadsorbed fraction, and carrying out the fractional purification of the fraction. CONSTITUTION:A liquid containing various proteins (e.g. enolase, calmodulin, S-100 protein, glia fibrillary protein, etc.) is made to contact with CH3-(CH2)n- (water-insoluble carrier) (n is 3-7) or NH2-(CH2)m-(water-insoluble carrier) (m is 4-8). Various proteins adsorbed to the water-insoluble carrier are subjected to the fractional eluation with a salt such as sodium chloride, an hydrophobic solvent such as alcohol, a surface active agent, an amine, etc. Various protein components of the brain of a mammal can be separated and purified at the same time, in high yield.
Hepatocellular carcinoma (HCC), a hypervascular tumor, is the most frequent primary malignant tumor of the liver. Angiogenesis inhibitors, such as endogenous angiogenesis inhibitors, are essential for HCC therapy and have generated significant interest owing to their safety, efficacy, and multitargeting attributes. Canstatin is an angiogenesis inhibitor derived from the basement membrane and exerts anti-tumor effects. However, the inhibitory effects and underlying mechanisms of action of canstatin on HCC remain unclear. Therefore, in this study, HepG2 and Huh7 cells were used to investigate the inhibitory effects of recombinant canstatin on HCC cells. Subsequently, the biosafety and inhibitory effects of recombinant canstatin on tumor growth were investigated in a xenograft animal model of liver cancer. Canstatin inhibited the growth of liver cancer cells by regulating their proliferation, apoptosis, and migration. Additionally, it suppressed the occurrence and progression of HCC by modulating the HIF-1α/VEGF signaling pathway. In mice, canstatin exerted no discernible harmful side effects and suppressed the growth of HCC subcutaneous xenograft tumors. Overall, our findings shed light on the molecular pathways underlying canstatin-induced HCC cell death that may help develop novel HCC treatments.
The patients will receive an external bracing (3-point hyperextension brace) for six weeks, which must be always worn except when lying flat in bed. The brace is adjusted by an experienced orthopedist. A physiotherapist will instruct the patient to accomplish daily activities with the restriction he or she will have by wearing the brace.
Doxorubicin, the most prescribed chemotherapeutic drug, causes dose-dependent cardiotoxicity and heart failure. However, our understanding of the immune response elicited by doxorubicin is limited. Here we show that an aberrant CD8+ T cell immune response following doxorubicin-induced cardiac injury drives adverse remodeling and cardiomyopathy. Doxorubicin treatment in non-tumor-bearing mice increased circulating and cardiac IFNγ+CD8+ T cells and activated effector CD8+ T cells in lymphoid tissues. Moreover, doxorubicin promoted cardiac CD8+ T cell infiltration and depletion of CD8+ T cells in doxorubicin-treated mice decreased cardiac fibrosis and improved systolic function. Doxorubicin treatment induced ICAM-1 expression by cardiac fibroblasts resulting in enhanced CD8+ T cell adhesion and transformation, contact-dependent CD8+ degranulation and release of granzyme B. Canine lymphoma patients and human patients with hematopoietic malignancies showed increased circulating CD8+ T cells after doxorubicin treatment. In human cancer patients, T cells expressed IFNγ and CXCR3, and plasma levels of the CXCR3 ligands CXCL9 and CXCL10 correlated with decreased systolic function.
