Tissue optical clearing enhances efficacy of vascular targeted photodynamic therapy of mouse dorsal skin

Vascular-targeted photodynamic therapy(V-PDT)is an effective treatment for port wine stains(PWS).However,repeated treatment is usually needed to achieve optimal treatment outcomes,possibly due to the limited treatment light penetration depth in the PWS lesion.The optical clearing technique can increase light penetration in depth by reducing light scattering.This study aimed to investigate the V-PDT in combination with an optical clearing agent(OCA)for the therapeutic enhancement of V-PDT in the rodent skinfold window chamber model.Vascular responses were closely monitored with laser speckle contrast imaging(LSCI),optical coherence tomography angiography,and stereo microscope before,during,and after the treatment.We further quantitatively demonstrated the effects of V-PDT in combination with OCA on the blood flow and blood vessel size of skin microvasculature.The combination of OCA and V-PDT resulted in significant vascular damage,including vasoconstriction and the reduction of blood flow.Our results indicate the promising potential of OCA for enhancing V-PDT for treating vascular-related diseases,including PWS.

Predictors of cerebrospinal fluid GeneXpert MTB/RIF positivity in patients with tuberculous meningitis:A prospective cohort study

Objective:To identify the clinical,laboratory,and radiological markers that could predict a positive GeneXpert result in patients suspected of tuberculous meningitis.Methods:In this prospective,observational study,patients with tuberculous meningitis were systematically evaluated.Various clinical,laboratory[including cerebrospinal fluid(CSF)microscopy,culture,and GeneXpert],and neuroimaging factors were examined.All participants were administered anti-tuberculous treatment and corticosteroids.A six-month follow-up was done to evaluate the outcome.Results:Of the 116 patients studied,54(46.6%)tested positive for GeneXpert,while 62(53.4%)were negative.Third cranial nerve involvement(OR 3.71,95%CI 1.052-13.09,P=0.04)and the presence of basal exudates on neuroimaging(OR 5.22,95%CI 2.03-13.42,P=0.001)emerged as independent predictive factors for a positive GeneXpert result.A positive CSF GeneXpert result(P=0.002)and drug resistance(P=0.004)were significantly linked to adverse outcomes.Additionally,a high score on the Medical Research Council stageⅢ(OR 5.64,95%CI 1.18-26.87,P=0.03)and elevated CSF cell counts(OR 1.002,95%CI 1.00-1.001,P=0.03)were identified as independent predictors of poor prognosis.Conclusions:Third cranial nerve involvement and the presence of basal exudates were significant indicators of a positive GeneXpert result.MRC stageⅢdisability and elevated CSF cell counts predicted poor outcomes.

Early diagnosis of esophageal cancer:How to put“early detection”into effect?

This editorial comments on the article by Qu et al in a recent edition of World Journal of Gastrointestinal Oncology,focusing on the importance of early diagnosis in managing esophageal cancer and strategies for achieving“early detection”.The five-year age-standardized net survival for esophageal cancer patients falls short of expectations.Early detection and accurate diagnosis are critical strategies for improving the treatment outcomes of esophageal cancer.While advancements in endoscopic technology have been significant,there seems to be an excessive emphasis on the latest high-end endoscopic devices and various endoscopic resection techniques.Therefore,it is imperative to redirect focus towards proactive early detection strategies for esophageal cancer,investigate the most cost-effective screening methods suitable for different regions,and persistently explore practical solutions to improve the five-year survival rate of patients with esophageal cancer.

Broad Hormonal Responses Induced by Aluminum in Roots of Dwarf Transgenics of Solanum lycopersicum L. cv “Micro-Tom”

The spatial pattern distribution of plant hormones in response to aluminum (Al) toxicity in roots remains to be shown. This study was performed to assess the root hormonal accumulation and gene expression in response to Al toxicity in five transgenic miniature dwarf tomatoes cv. Micro-Tom (MT). MT and MT transgenics to acid indole acetic, cytokinin, gibberellin, abscisic acid and ethylene were cultivated in nutrient solutions containing different Al concentrations. Root growth elongation was measured and cellular damage was visualized by staining Evans’s blue. The GUS reporter gene staining technique was used to visualize hormonal changes in MT apex root tissues. Data indicated that the MT is sensitive to Al that induced significant growth inhibition and cellular damage. Al concentration of 27 μM was significantly toxic, inducing root apex darkening and inhibition of root development. The qualitative evaluation of GUS reporter gene expression showed intense crosstalk among all hormones studied, underscoring the complexity of signaling induced by Al in apex roots. Results point out to a major understanding of the hormonal signaling in response to Al toxicity, which may induce a change of root growth and architecture with growth inhibition and cell constraints modulated by all different hormones evaluated.

The relationship between the distribution of HBcAg in liver cells and the pathological manifestations of the liver in 429 HBeAg-positive chronic HBV-infected individuals

Background:The natural history of chronic HBV infection is typically characterized by four stages:the immune tolerance period,the immune clearance period,the immune control period,and the immune escape period.These stages are associated with the distribution of HBcAg in liver cells;however,this relationship remains a topic of broad debate within the field of liver disease.To objectively and quantitatively measure the intracellular distribution of HBcAg,this paper aims to design a method referred to as the“layered evaluation method”and to examine its validation.Methods:The distribution of HBcAg in liver cells is assessed using Image Pro Plus image processing software,along with calculations of cytoplasmic and nuclear positive staining rates.Results:The findings indicate that the highest proportion of patients exhibited a positive cytoplasmic expression rate ranging from 0-2.5%.More than 40% of the total sample was categorized within the 0-2.5% positive nuclear expression range.The HBcAg cytoplasmic positive staining rates were classified into five levels:a cytoplasmic HBcAg positive staining rate of less than 0.05% is designated as level 0,indicating negative expression;a staining rate between 0.05% and 5% is classified as level 1;a rate from 5% to less than 10% is classified as level 2;a rate from 10% to less than 20% is classified as level 3;and a nuclear positivity rate exceeding 20% is classified as level 4.Conclusion:The inflammatory activity grade in these patients was positively correlated with the cytoplasmic distribution of HBcAg.Furthermore,the nuclear distribution rate of HBcAg was significantly higher in the G3 group compared to the other groups.

This study confirms the efficacy of the flashlamp- pumped pulsed dye laser in the treatment of port- wine stains in children and adults.

Evaluation of Fluorescent Stains for Viability Assessment of the Potato Cyst Nematodes <i>Globodera pallida</i>and <i>G. ellingtonae</i>

Potato cyst nematodes (PCNs), Globodera pallida and Globodera rostochiensis, are quarantine pests of potato which cause significant damage to production and farm gate revenue worldwide. Accurately assessing viability of PCN eggs is important for eradication and management programs. The goal of this study was to develop a quick and reliable fluorescent staining method to evaluate viability of G. pallida and Globodera ellingtonae eggs. The staining efficiency of eight fluorescent stains was evaluated using G. pallida eggs compared with the conventional Meldola’s Blue (MB) staining method. The staining efficiency of the fluorescent stains ranged from 80.33 ± 2.99 (Sytox Green) to 100% (Acridine Orange) for non-viable eggs. Two stains were further evaluated for their efficiency in assessing viability of encysted eggs from five different greenhouse-reared G. pallida cyst sources which contained both viable and non-viable eggs. For the G. pallida cyst sources, viability ofencysted eggs were estimated to be 41.02 ± 3.81 to 62.66% ± 3.12% when stained with Acridine Orange (AO) and 79.52% ± 1.54% viability for G. ellingtonae. Both staining time and stain concentration were significant for staining efficiency of released and encysted eggs. Staining time and concentration were optimized for released eggs at 4 h at 10 μg/ml and for encysted eggs at 16 h at 25 μg/ml respectively for AO. Fluorescent stains accurately and rapidly assessed percent egg viability and were determined to be as sensitive as a seven-day incubation with the Meldola’s Blue staining method.

Diagnostic Performance of glmM Gene and Histological Stains for Detection of Helicobacter pylori in Gastric Biopsy from Patients Admitted to Wad Madani Teaching Hospital, Sudan

Helicobacter pylori is the microbial agent most responsible for gastro-duodenal ulcer and chronic gastritis, which can develop into carcinoma of the stomach. This study was performed in Wad Medani Teaching Hospital, Sudan to detect Helicobacter pylori in stomach samples, and evaluate the performance of the tests used, which were histological stains and PCR. Gastric biopsies were obtained from 105 referred patients during endoscopy, and fixed specimens examined by haematoxylin-eosin and Warthin-Starry silver stains, while DNA was extracted for glmM gene amplification. Epigastric pain was the most common symptom at 78% (82/105) and chronic gastritis recorded with 71% (68/105) of endoscopy results. Warthin-Starry silver stain gave 31% (33/105) as positive for Helicobacter pylori followed by glmM gene 27% (28/105) and haematoxylin-eosin 24% (25/105). The study indicated good performance of histological staining and high specificity of glmM gene in detection of Helicobacter pylori from gastric biopsies.

Application of short-pulsed CO_(2) laser and long-pulsed Nd:YAG laser in the treatment of severe hypertrophic port-wine stains

Background:The treatment of port-wine stains(PWS)becomes extremely difficult due to age-related malformation of the vasculature.In this study,we used alternative methods to treat hypertrophic PWS.Methods:A short-pulsed CO_(2) laser was applied to ablate the hypertrophic vasculature of PWS.The ablation was ended when the wound was on the same plane as normal skin.The long-pulsed neodymium-doped yttriumaluminum-garnet(lpNd:YAG)laser was primarily applied to coagulate and subsequently liquefy the hypertrophic vasculature of the PWS.The therapeutic energy used in treating different lesions should be carefully regulated to significantly affect the treatment outcomes.Results:The two cases presented herein demonstrated substantial improvement in hypertrophic vasculature that was largely removed.The skin was resurfaced,although some scar formation and mild hypopigmentation occurred.Conclusion:We suggest the use of short-pulsed CO_(2) and lpNd:YAG lasers for treating certain cases of hypertrophic PWS.When using a short-pulsed CO_(2) laser,it is wise to judge the treatment endpoint and take appropriate precautions to avoid intraoperative bleeding.When using an lpNd:YAG laser,the therapeutic energy should be controlled according to the thickness of the lesion to reduce scar formation.

Stains on imperfect textile

The imperfect material effect is one of the most important themes to obtain photo-realistic results in rendering.Textile material rendering has always been a key area in the field of computer graphics.So far,a great deal of effort has been invested in its unique appearance and physics-based simulation.The appearance of the dyeing effect commonly found in textiles has received little attention.This paper introduces techniques for simulation of staining effects on textiles.Pulling,wearing,squeezing,tearing,and breaking effects are more common imperfect effects of fabrics,these external forces will cause changes in the fabric structure,thus affecting the diffusion effect of stains.Based on the microstructure of yarn,we handle the effect of the stain on the imperfect textile surface.Our simulation results can achieve a photo-realistic effect.

Protective effect of liraglutide on the myocardium of type 2 diabetic rats by inhibiting polyadenosine diphosphate-ribose polymerase-1

BACKGROUND In recent years,studies have found that the occurrence and development of diabetic cardiomyopathy(DCM)is closely related to an increase in polyadenosine diphosphate-ribose polymerase-1(PARP-1)activity.PARP-1 activation could be involved in the pathophysiological process of DCM by promoting oxidative stress,the inflammatory response,apoptosis and myocardial fibrosis.AIM To investigate the mechanism of liraglutide in improving myocardial injury in type 2 diabetic rats,further clarified the protective effect of liraglutide on the heart,and provided a new option for the treatment of DCM.METHODS Forty healthy male SD rats aged 6 wk were randomly divided into two groups,a normal control group(n=10)and a model group(n=30),which were fed an ordinary diet and a high-sugar and high-fat diet,respectively.After successful modeling,the rats in the model group were fed a high-glucose and high-fat diet for 4 wk and randomly divided into a model group and an intervention group(further divided into a high-dose group and a low-dose group).The rats were fed a high-glucose and high-fat diet for 8 wk and then started drug intervention.Blood samples were collected from the abdominal aorta to detect fasting blood glucose and lipid profiles.Intact heart tissue was dissected,and its weight was used to calculate the heart weight index.Haematoxylin and eosin staining was used to observe the pathological changes in the myocardium and the expression of PARP-1 in the heart by immunohistochemistry.RESULTS The body weight and heart weight index of rats in the model group were significantly increased compared with those in the normal control group,and those in the intervention group were decreased compared with those in the model group,with a more obvious decrease observed in the high-dose group(P<0.05).In the model group,myocardial fibers were disordered,and inflammatory cells and interstitial fibrosis were observed.The cardiomyopathy of rats in the intervention group was improved to different degrees,the myocardial fibers were arranged neatly,and the myocardial cells were clearly striated;the improvement was more obvious in the high-dose group.Compared with the normal control group,the expression of PARP-1 in myocardial tissue of the model group was increased,and the difference was statistically significant(P<0.05).After liraglutide intervention,compared with the model group,the expression of PARP-1 in myocardial tissue was decreased,and the reduction was more obvious in the high-dose group(P<0.05)but still higher than that in the normal control group.CONCLUSION Liraglutide may improve myocardial injury in type 2 diabetic rats by inhibiting the expression of myocardial PARP-1 in a dose-dependent manner.

Early brainstem hemorrhage progression:multi-sequence magnetic resonance imaging and histopathology

According to clinical statistics,the mortality of patients with early brainstem hemorrhage is high.In this study,we established rat models of brainstem hemorrhage by injecting type Ⅶ collagenase into the right basotegmental pontine and investigated the pathological changes of early brainstem hemorrhage using multi-sequence magnetic resonance imaging and histopathological methods.We found that brainstem hematoma gradually formed in the injured rats over the first 3 days and then reduced after 7 days.The edema that occurred was mainly of the vasogenic type.No complete myelin sheath structure was found around the focus of the brainstem hemorrhage.The integrity and continuity of nerve fibers gradually deteriorated over the first 7 days.Neuronal degeneration was mild in the first 3 days and then obviously aggravated on the 7^(th)day.Inflammatory cytokines,interleukin-1β,and tumor necrosis factorαappeared on the 1st day after intracerebral hemorrhage,reached peak levels on the 3^(rd)day,and decreased from the 7^(th)day.Our findings show the characteristics of the progression of early brainstem hemorrhage.

Invasive breast carcinoma with osteoclast-like stromal giant cells:A case report

BACKGROUND Invasive breast carcinoma with osteoclast-like stromal giant cells(OGCs) is an extremely rare morphology of breast carcinomas.To the best of our knowledge,the most recent case report describing this rare pathology was published six years ago.The mechanism controlling the development of this unique histological formation is still unknown.Further,the prognosis of patients with OGC involvement is also controversial.CASE SUMMARY We report the case of a 48-year-old woman,who presented to the outpatient department with a palpable,growing,painless mass in her left breast for about one year.Sonography and mammography revealed a 26.5 mm ×18.8 mm asymmetric,lobular mass with circumscribed margin and the Breast Imaging Reporting and Data System was category 4C.Sono-guided aspiration biopsy revealed invasive ductal carcinoma.The patient underwent breast conserving surgery and was diagnosed with invasive breast carcinoma with OGCs,grade Ⅱ,with intermediate grade of ductal carcinoma in situ(ER:80%,3+,PR:80%,3+,HER-2:negative,Ki 67:30%).Adjuvant chemotherapy and post-operation radiotherapy were initiated thereafter.CONCLUSION As a rare morphology of breast cancer,breast carcinoma with OGC occurs most often in relatively young women,has less lymph node involvement,and its occurrence is not racedependent.

The superiority and feasibility of 2,3,5-triphenyltetrazolium chloride-stained brain tissues for molecular biology experiments based on microglial properties

Background:TTC(2,3,5-triphenyltetrazolium chloride)staining is the most commonly used method in identifying and assessing cerebral infarct volumes in the transient middle cerebral artery occlusion model.Given that microglia exhibit different morphologies in different regions after ischemic stroke,we demonstrate the superiority and necessity of using TTC-stained brain tissue to analyze the expression of various proteins or genes in different regions based on microglia character.Methods:We compared brain tissue(left for 10 min on ice)from the improved TTC staining method with penumbra from the traditional sampling method.We identified the feasibility and necessity of the improved staining method using real time(RT)-PCR,Western blot,and immunofluorescence analysis.Results:There was no protein and RNA degradation in the TTC-stained brain tissue group.However,the TREM2 specifically expressed on the microglia showed a significant difference between two groups in the penumbra region.Conclusions:TTC-stained brain tissue can be used for molecular biology experiments without any restrictions.In addition,TTC-stained brain tissue shows greater superiority due to its precise positioning.
