Thioredoxin (a small dithiol protein) is a specific reductant for allergenic proteins and particularly allergenic proteins present in pollen and animal and plant sources. All targeted proteins contain disulfide (S-S) bonds that are reduced to the sulfhydryl (SH) level by thioredoxin. The proteins are allergenically active and less digestible in the oxidized (S-S) state. When reduced (SH state), they lose their allergenicity and/or become more digestible. Thioredoxin achieved this reduction when activated (reduced) either by NADPH via NADP-thioredoxin reductase (physiological conditions) or by lipoic acid chemical reductant. Skin tests carried out with sensitized dogs showed that treatment of the pollens with reduced thioredoxin prior to injection eliminated or decreased the allergenicity of the pollen. Studies showed increased digestion of the pollen proteins by pepsin following reduction by thioredoxin. Pollen proteins that have been reduced by thioredoxin are effective and safe immunotherapeutic agents for decreasing or eliminating an animal's allergic reaction that would otherwise occur upon exposure to the non-reduced pollen protein.

Mitochondrial dysfunction with aging is associated with the development of age-related hearing loss. Mitophagy is a cardinal mechanism to maintain a healthy mitochondrial population through the turnover of damaged mitochondria. Declining mitophagy with age causes a buildup of damaged mitochondria, leading to sensory organ dysfunction. The effect of Urolithin A (UA), a mitophagy inducer, was investigated on age-related hearing loss in a mouse model. C57BL/6J mice were treated with UA from 6 to 10 months of age. UA attenuated an auditory brainstem responses (ABR) threshold shift at 8, 16, and 32 kHz frequencies, and improved mitochondrial DNA integrity and ATP production in the cochlea and auditory cortex. The mRNA levels of mitophagy-related genes and protein levels of PINK1, Parkin, BNIP3, and LC3B increased in the cochlea and auditory cortex. The expression of mitophagosomes and mitophagolysosomes in the cochlea, spiral ganglion, auditory cortex, and inferior colliculus increased, together with the expression of Parkin and BNIP3 in the cochlea, spiral ganglion, auditory cortex, and inferior colliculus. These results indicate that UA counteracted mitophagy decline in the auditory system and prevented age-related hearing loss. UA can be used as a potential agent to prevent age-related hearing loss.
Ropinirole hydrochloride has been administered to 1,599 individuals in clinical trials. During these trials, all adverse events were recorded by the clinical investigators using terminology of their own choosing. To provide a meaningful estimate of the proportion of individuals having adverse events, similar types of events were grouped into a smaller number of standardized categories using modified WHOART dictionary terminology. These categories are used in the listing below. The frequencies presented represent the proportion of the 1,599 individuals exposed to ropinirole hydrochloride who experienced events of the type cited on at least 1 occasion while receiving ropinirole hydrochloride. All reported events that occurred at least twice (or once for serious or potentially serious events), except those already listed above, trivial events, and terms too vague to be meaningful, are included without regard to determination of a causal relationship to ropinirole hydrochloride, except that events very unlikely to be drug-related have been deleted.

Events are further classified within body system categories and enumerated in order of decreasing frequency using the following definitions: frequent adverse events are defined as those occurring in at least 1/100 patients and infrequent adverse events are those occurring in 1/100 to 1/1,000 patients and rare events are those occurring in fewer than 1/1,000 patients.

This study focuses on exploring the role of Six2 in the progression of hepatocellular carcinoma (HCC) and its resistance to the chemotherapy drug 5-fluorouracil (5-FU). Using Hep3B and Huh7 cell lines, we analyzed how Six2 affects various cellular functions, including viability, proliferation, apoptosis, and invasion. Our research also delved into Six2's regulatory impact on DNMT1 levels, E-cadherin expression, and the methylation of the E-cadherin promoter, all of which are crucial for 5-FU resistance in HCC cells. Additionally, we examined the effects of Six2 knockdown on the PI3K/AKT/mTOR signaling pathway. Our findings indicate that overexpression of Six2 enhances cell viability and proliferation, encourages invasive behavior, increases methylation at the E-cadherin promoter, and reduces apoptosis. These changes correspond with increased levels of DNMT1 and decreased levels of E-cadherin, culminating in heightened resistance to 5-FU. Conversely, knocking down Six2 increases the sensitivity of HCC cells to 5-FU and reduces activation of the PI3K/AKT/mTOR pathway. These results suggest that Six2 plays a significant role in promoting HCC proliferation, invasion, and chemotherapy resistance, particularly through mechanisms involving DNMT1 and the PI3K/AKT/mTOR pathway, highlighting its potential as a target for HCC treatment.
A proportion of patients clinically diagnosed with Parkinson's disease (PD) can have a 123I-FP-CIT-SPECT scan without evidence of dopaminergic deficit (SWEDD), generating a debate about the underlying biological mechanisms. This study investigated differences in clinical features, 123I-FP-CIT binding, molecular connectivity, as well as clinical and imaging progression between SWEDD and PD patients. We included 36 SWEDD, 49 de novo idiopathic PD, and 49 healthy controls with 123I-FP-CIT-SPECT from the Parkinson's Progression Markers Initiative. Clinical and imaging 2-year follow-ups were available for 27 SWEDD and 40 PD. Regional-based and voxel-wise analysis assessed dopaminergic integrity in dorsal and ventral striatal, as well as extrastriatal regions, at baseline and follow-up. Molecular connectivity analyses evaluated dopaminergic pathways. Spatial correlation analyses tested whether 123I-FP-CIT-binding alterations would also pertain to the serotoninergic system. SWEDD and PD patients showed comparable symptoms at baseline, except for hyposmia, which was more severe for PD. PD showed significantly lower striatal and extrastriatal 123I-FP-CIT-binding compared to SWEDD and controls. SWEDD exhibited lower binding than controls in striatal regions, insula, and olfactory cortex. Both PD and SWEDD showed extensive altered connectivity of dopaminergic pathways, however, with major impairment in the mesocorticolimbic system for SWEDD. Motor symptoms and dopaminergic deficits worsened after 2 years for PD only. The limited dopaminergic impairment and its stability over time observed for SWEDD, as well as the presence of extrastriatal 123I-FP-CIT binding alterations and prevalent mesocorticolimbic connectivity impairment, suggest other mechanisms contributing to SWEDD pathophysiology.
The aim of this research is to determine the effect of hot water foot bath applied in the early period after cesarean section on pain, fatigue and gas release. This research is a randomized controlled trial. The study was conducted in Gaziantep Abdulkadir Yuksel Hospital. The sample of the research consisted of 80 women who gave birth by cesarean section (experimental group: 40 and control group: 40). The women in the study were randomly assigned to the experimental and control groups before starting the application. The data were collected between 01 December 2021 and 31 June 2022. 'Descriptive Information Form', 'Numerical Rating Scale', 'Visual Analogue Scale for Fatigue', 'Experimental Group Patient Follow-up Form', 'Control Group Patient Follow-up Form' were used as data collection tools. Hot water foot bath was applied to the experimental group for 15 minutes 3 hours after the cesarean section. The control group was only followed up after cesarean section. In the comparison of the experimental and control groups, chi-square for categorical variables, and independent samples t-test for numerical variables were used. Independent samples t-test was used to compare the scale scores of the experimental and control groups. In the comparison of the scale scores that were measured at different times, the Repeated Measurements Analysis of Variance was applied and the Least Significant Difference(LSD) test, which is one of the multiple comparison tests, was used. It was found that the pain level of the women after the hot water foot bath application in the experimental group was lower than that of the control group and the measurements before the application. It was determined that the fatigue levels of the women in the experimental group after the application were lower than the control group and the measurements before the application. It was determined that the application of hot water foot bath was not effective in the period of gas release after cesarean section. As a result, it was determined that the hot water foot bath applied in the early period after cesarean section reduced the level of pain and fatigue, and had no effect on gas release. During the post-cesarean section, a hot water foot bath can be recommended in nursing care.
INTRODUCTION: Peruvian young transgender women (YTW) ages 16-24 years are a critical but understudied group for primary HIV prevention efforts, due to sharp increases in HIV prevalence among TW ages 25 years and older.
METHODS: Between February and July 2022, a cross-sectional quantitative study with YTW ages 16-24 years in Peru (N = 211) was conducted consisting of a bio-behavioural survey accompanied by laboratory-based testing for HIV and sexually transmitted infections (STIs). Bivariate and multivariable Poisson regression models were used to estimate prevalence ratios between socio-demographic and behavioural characteristics and HIV status.
RESULTS: HIV prevalence was 41.5% (95% CI: 33.9-49.4%), recent syphilis acquisition 19.4% (95% CI: 12.7-28.4), chlamydia 6.3% (95% CI: 3.1-11.1) and gonorrhoea 12.3% (95% CI: 7.9-18.7). Almost half (47.9%) reported condomless anal sex in the past 6 months, 50.7% reported sex work in the past 30 days and 13.7% reported accepting more money for condomless sex. There were no significant differences in reported sexual behaviours by HIV status. Only 60.8% of participants reported ever having been tested for HIV, and 25.6% reported a past 6-month STI test. More than two-thirds (67.8%) had not heard of antiretroviral pre-exposure prophylaxis (PrEP) and only 4.7% had taken PrEP in the past month. Current moderate-to-severe psychological distress was endorsed by 20.3%, 10.0% reported attempting suicide in the past 6 months and 85.4% reported alcohol misuse.
CONCLUSIONS: Findings show that the HIV epidemic for YTW in Lima, Peru is situated in the context of widespread social exclusion, including economic vulnerabilities, violence victimization and the mental health sequelae of transphobic stigma that starts early in life. Future research should aim to further understand the intersection of these vulnerabilities. Moreover, there is an urgent necessity to design and evaluate HIV prevention programmes that address the root systems driving HIV vulnerabilities in YTW and that focus on developmentally specific clusters of stigma-related conditions.
Patients receive Entecavir in a dosage of 0.5 mg once daily per os from day 0, up to week 48. From week 24 to week 48, they also receive pegylated-interferon a-2a in a dose of 180 μg per week s.c. At week 48, response will be assessed. Responders will continue to take Entecavir until week 72, and quit subsequently. Non-responders at week 48 will continue on Entecavir up to week 96.
Considered the second most frequent cause of death worldwide , the stroke is also responsible for the largest number of functional disability in individuals. The socio - economic hardship that many patients face to perform a program of intensive rehabilitation sensorimotor, has led to functional limitations in many cases , promote irreversible consequences. Spasticity in the upper and lower limb after stroke results in loss of function and mobility being the key therapeutic approaches in order to restore its function. Currently, the Virtual therapy has been used in physical therapy, demonstrating safety, feasibility and potential to facilitate the effective rehabilitation treatment, promoting motor recovery. The objective of this study is to analyze and compare the effectiveness of virtual therapy and conventional physiotherapy in paretic upper and lower limbs of patients with sensory motor deficit after stroke. Virtual therapy will be based on a custom application using virtual reality projection, and conventional treatment will be based on cinesiotherapy for members upper and lower paretic. The evaluation will be performed by biomedical instrumentation using dynamometry, electromyography and analysis from functional movement. Statistical differences are based on t test with significance level of p 0 , 05 . As a result expected - scientifically proven the effectiveness of this new form of treatment aimed at improving quality of life and functional independence of patients with neurological sequel.
BACKGROUND: Chronic heart failure (CHF) impairs cognitive function, yet its effects on brain structure and underlying mechanisms remain elusive. This study aims to explore the mechanisms behind cognitive impairment.
METHODS: CHF models in rats were induced by ligation of the left anterior descending coronary artery. Cardiac function was analyzed by cardiac ultrasound and hemodynamics. ELISA, immunofluorescence, Western blot, Golgi staining and transmission electron microscopy were performed on hippocampal tissues. The alterations of intestinal flora under the morbid state were investigated via 16S rRNA sequencing. The connection between neuroinflammation and synapses is confirmed by a co-culture system of BV2 microglia and HT22 cells in vitro. Results: CHF rats exhibited deteriorated cognitive behaviors. CHF induced neuronal structural disruption, loss of Nissl bodies, and synaptic damage, exhibiting alterations in multiple parameters. CHF rats showed increased hippocampal levels of inflammatory cytokines and activated microglia and astrocytes. Furthermore, the study highlights dysregulated PDE4-dependent cAMP signaling and intestinal flora dysbiosis, closely associated with neuroinflammation, and altered synaptic proteins. In vitro, microglial neuroinflammation impaired synaptic plasticity via PDE4-dependent cAMP signaling.
CONCLUSIONS: Neuroinflammation worsens CHF-related cognitive impairment through neuroplasticity disorder, tied to intestinal flora dysbiosis. PDE4 emerges as a potential therapeutic target. These findings provide insightful perspectives on the heart-gut-brain axis.

Lifestyle intervention will consist of two integrated components i.e. physical activity and dietary supplementation with inorganic nitrate. The physical activity component aims to increase daily physical activity level by at least 2000 steps/day from baseline (e.g. walking for approximately 30 minutes), at least 5-7 days per week. The second component of the lifestyle intervention is a dietary supplementation with inorganic nitrate. A single dose of inorganic nitrate given in the form of concentrated nitrate-rich beetroot juice (NO3-, BEET IT Sport, James White Drinks Ltd., Ipswich, UK) containing 6 mmol of NO3- in 70 ml bottle.
PURPOSE: This study aimed to examine and analyze the presence of sexual dimorphism and symmetry/asymmetry in fixed cadaveric heads and their contributions to clinical practice.
METHODS: Measurements were conducted on 6 cadavers and 24 fixed cadaveric heads (n = 30) using a digital microcaliper to assess cranial dimensions, including surgical landmarks, facial index (FI), orbital index (OI), and the danger triangle of the face, offering crucial references for surgeons during surgical interventions.
RESULTS: Analyses were conducted on cadavers consisting of 10 females (33.3%) and 20 males (66.7%). Males demonstrated significantly higher values than females in terms of Zy-Zy (Zy = Zygion), nasal body, and width/length of the columella. Hyperleptoprosop types were the most frequently observed, followed by the leptoprosop type. Females exhibited megaseme characteristics according to OI on both sides. Additionally, the danger triangle of the face was greater in males compared than in females, suggesting a higher risk of infection in this region among males.
CONCLUSION: The observed sex differences in facial and nasal dimensions, along with facial indices, are crucial for customizing surgical procedures to individual patients. For example, the greater distance in the danger triangle among males highlights the importance of considering anatomical variations to avoid complications, such as septic cavernous sinus thrombosis. Integrating these measurements into preoperative planning can enhance the precision of facial reconstruction and aesthetic surgeries, thereby improving patient outcomes and safety.
All patients in both groups were applied with a hot pack for 40-minutes, transcutaneous electrical nerve stimulation for 30-minutes (100 Hz frequency and 60 milliseconds pulse duration), and a home-based exercise program around the knee for 30-minutes per day for three weeks. Also, each patient in group 1 received shockwaves of continuous frequency and intensity (2000 shocks, 10 Hz, 2.0 to 3.0 bar), while the second group of patients received sham-ESWT. In group 1, for a total of 3 weeks, r-ESWT was undertaken with 2000 pulse each time at a week interval totaling 6000 pulse by using a radial shock wave therapy system (vibrolith ortho tip ESWT (ELMED Turkey)).
BACKGROUND: Acute glaucoma is a potential complication of carotid revascularization procedures such as endarterectomy or stenting. Although preoperative ocular hypoperfusion may predispose patients to postoperative glaucoma, the details of this complication have not been clarified.
METHODS: We retrospectively reviewed the medical records of consecutive patients who underwent carotid revascularization at our institution from January 2019 to December 2022. These patients were divided into glaucoma and nonglaucoma groups. Given the rarity of the event, a systematic literature review was performed to additionally include data from patients who developed acute glaucoma after carotid revascularization. Multivariate logistic regression was performed to identify the risk factors for acute glaucoma.
RESULTS: Thirty-five cases, including 2 from our institution, were included in the glaucoma group, and 130 were included in the nonglaucoma group. Most cases (79%) occurred within five days postoperatively. Multivariate analysis revealed that preoperative ocular symptoms were significantly associated with the development of postoperative glaucoma (odds ratio, 361.06; 95% confidence interval, 34.09-3824.27; P < 0.001). Preoperative neovascularization at the iris or anterior chamber angle, indicating severe ocular hypoperfusion, was found in 84% of patients with glaucoma. Permanent visual loss occurred in 41% of patients. The incidence of postoperative glaucoma at our institution was 1.5% (2/132). The positive predictive value of preoperative ocular symptoms for postoperative glaucoma was 0.25 (95% confidence interval, 0.18-0.32).
CONCLUSIONS: This study was the first to clarify the risk factors and characteristics of acute glaucoma after carotid revascularization.
PURPOSE:To collect glucan having improved carcinostatic activity in high yield, by subjecting a culture fluid of Cordyceps ophioglossoides Fr, to a specific purification treatment. CONSTITUTION:(i) Cordyceps ophioglossoides Fr. (available from the Institute for Fermentation, Osaka) is cultivated in an agar plate culture medium to grow mycelia on the surface thereof, and the resultant mycelia are cultivated in a liquid culture medium at about 20-30 deg.C. (ii) The resultant highly viscous culture is mixed with distilled water in an amount of about 2-3 times of that of the culture and then centrifuged to remove the mycelia. The resultant cultivation filtrate is then dialyzed to remove low-molecular weight substances (having <=1,000 molecular weight). (iii) An equal amount of ethanol is added to the resultant cultivation filtrate, and the resultant mixture is allowed to stand in a cold place overnight to precipitate crude glucan, which is dissolved in an aqueous solution of acetic acid. The resultant solution is then kept at 35-100 deg.C to deposit the glucan. After cooling the solution, the glucan is collected, washed with water and dried under reduced pressure to afford the aimed purified glucan powder.
