FIELD: medicine, stomatology. SUBSTANCE: method involves preliminary mouth cavity preparing by removing mouth fluid and washing with water. In the second portion of nonstimulated mixed saliva the parent activity of enzyme leucine aminopeptidase is determined as a pathognomonic factor of microorganisms activity. Then the tested prophylaxis agent is exposed for 2-4 min followed by determination of microorganism suppression by inactivation of leucine aminopeptidase. Similar studies were carried out after 1, 3, 7 days and an average index of leucine aminopeptidase activity is calculated. Tested preparation is evaluated to be high effective if enzyme activity decrease is 45% and above; mean effectiveness of preparation is evaluated at 30-44% decrease activity and low effectiveness - at less 30% enzyme activity decrease. EFFECT: improved method of assay.
We aimed to evaluate fetal and placental oxygen saturation (sO2) in anemic and non-anemic pregnant rats throughout gestation using photoacoustic imaging (PAI). Female Sprague-Dawley rats were fed an iron-restricted or iron-replete diet before and during pregnancy. On gestational days 13, 18, and 21, PAI was coupled with high resolution ultrasound to measure oxygenation of the fetus, whole placenta, mesometrial triangle, as well as the maternal and fetal faces of the placenta. PAI was performed in 3D, which allowed sO2 to be measured within an entire region, as well as in 2D, which enabled sO2 measurements in response to a hypoxic event in real time. Both 3D and 2D PAI were performed at varying levels of FiO2 (fraction of inspired oxygen). Iron restriction caused anemia in dams and fetuses, a reduction in fetal body weight, and an increase in placental weight, but overall had minimal effects on sO2. Reductions in FiO2 caused corresponding reductions in sO2 which correlated to the severity of the hypoxic challenge. Regional differences in sO2 were evident within the placenta and between the placenta and fetus. In conclusion, PAI enables non-invasive measurement of sO2 both rapidly and with a high degree of sensitivity. The lack of overt changes in sO2 levels between control and anemic fetuses may suggest reduced oxygen extraction and utilization in the latter group, which could be attributed to compensatory changes in growth and developmental trajectories.

BACKGROUND AND OBJECTIVE: Personalized 3D computer models of atria have been extensively implemented in the last yearsas a tool to facilitate the understanding of the mechanisms underlying different forms of arrhythmia, such as atrial fibrillation (AF). Meanwhile, genetic mutations acting on potassium channel dynamics were demonstrated to induce fibrillatory episodes in asymptomatic patients. This research study aims at assessing the effects and the atrial susceptibility to AF of three gain-of-function mutations - namely, KCNH2 T895M, KCNH2 T436M, and KCNE3-V17M - associated with AF outbreaks, using highly detailed 3D atrial models with realistic wall thickness and heterogenous histological properties.
METHODS: The 3D atrial model was generated by reconstructing segmented anatomical structures from CT scans of an AF patient. Modified versions of the Courtemanche human atrial myocyte model were used to reproduce the electrophysiological activity of the WT and of the three mutant cells. Ectopic foci (EF) were simulated in sixteen locations across the atrial mesh using an S1-S2 protocol with two S2 basic cycle lengths (BCL) and eleven coupling intervals in order to induce arrhythmias.
RESULTS: The three genetic mutations at 3D level reduced the APD90. The KCNE3-V17M mutation provoked the highest shortening (55 % in RA and LA with respect to WT), followed by KCNH2 T895M (14 % in RA and 18 % LA with respect to WT)and KCNH2 T436M (7 % in RA and 9 % LA with respect to WT). The KCNE3-V17M mutation led to arrhythmia in 67 % of the cases simulated and in 94 % of ectopic foci considered, at S2 BCL equal to 100 ms. The KCNH2 T436M and KCNH2 T895M mutations increased the vulnerability to AF in a similar way, leading to arrhythmic episodes in 7 % of the simulated conditions, at S2 BCL set to 160 ms. Overall, 60 % of the arrhythmic events generated arise in the left atrium. Spiral waves, multiple rotors and disordered electrical pattern were elicited in the presence of the KCNE3-V17M mutation, exhibiting an instantaneous mean frequency of 7.6 Hz with a mean standard deviation of 1.12 Hz. The scroll waves induced in the presence of the KCNH2 T436M and KCNH2 T895M mutations showed steadiness and regularity with an instantaneous mean frequencies in the range of 4.9 - 5.1 Hz and a mean standard deviation within 0.19 - 0.53 Hz.
CONCLUSIONS: The pro-arrhythmogenicity of the KCNE3-V17M, KCNH2 T895M and KCNH2 T436M mutations was studied and proved on personalized 3D cardiac models. The three genetic mutations were demonstrated to increase the predisposition of atrial tissue to the formation of AF-susceptible substrate in different ways based on their effects on electrophysiological properties of the atria.
Communication between glial cells has a profound impact on the pathophysiology of Alzheimer's disease (AD). We reveal here that reactive astrocytes control cell distancing in peri-plaque glial nets, which restricts microglial access to amyloid deposits. This process is governed by guidance receptor Plexin-B1 (PLXNB1), a network hub gene in individuals with late-onset AD that is upregulated in plaque-associated astrocytes. Plexin-B1 deletion in a mouse AD model led to reduced number of reactive astrocytes and microglia in peri-plaque glial nets, but higher coverage of plaques by glial processes, along with transcriptional changes signifying reduced neuroinflammation. Additionally, a reduced footprint of glial nets was associated with overall lower plaque burden, a shift toward dense-core-type plaques and reduced neuritic dystrophy. Altogether, our study demonstrates that Plexin-B1 regulates peri-plaque glial net activation in AD. Relaxing glial spacing by targeting guidance receptors may present an alternative strategy to increase plaque compaction and reduce neuroinflammation in AD.
This was a single centre, double-blind, randomised, placebo-controlled, single-graded-dose, crossover study with five single-dose treatment periods. The washout period between doses was 15±2 days. For each of the five treatment periods, volunteers were to be admitted at the UFH on the day before the treatment day. On each treatment period, the pre-dose assessment were to be completed, BIA 3-202/Placebo was to be administered concomitantly with the dose of Sinemet® 25/100 and post-dose assessments were to be completed. Subjects were discharged 30 h post-dose. Subjects should attend five treatment periods and were to receive a different dose of BIA 3-202 or placebo during each of these treatment periods.

Heat waves are lethal and cause a disproportionate number of deaths in the elderly relative to any other age group. Although gastrointestinal barrier dysfunction is a primary cause of heat related illness, little is known about the effects of aging on gastrointestinal barrier function during hyperthermia. The central hypothesis of this work is that the elderly exhibit greater gastrointestinal barrier dysfunction during hyperthermia. Participants will complete a control trial where gastrointestinal permeability (without heating) will be assessed in young and older adults. In the experimental trial, controlled hyperthermia will be achieved using a water perfused, tube lined suit. Core body temperature will be raised to a maximum of 2 degrees Celsius above the baseline value, or an absolute temperature of 39.5 degrees Celsius. Comprehensive assessments of gastrointestinal barrier function, microbial translocation and systemic inflammation will be assessed in young and older adults. The expected outcome of this work will re-shape out understanding of the consequences of aging on gastrointestinal barrier function during heat waves.
Type 2 diabetes mellitus (T2DM) patients had been randomized into two groups. During the 1st week the intervention group with stringent diet regime replaced 3 main meals by 50 g PRMR (Almased-Vitalkost, Almased Wellness GmbH, Bienenbüttel, Germany) each (=1100 kcal/day). In 2nd-4th week 2 meals were replaced and a protein-rich lunch was allowed. In 5th-12th week only dinner was replaced. The control group with moderate diet regime replaced breakfast and dinner for 4 weeks and then only dinner during the next 8 weeks. Clinical parameters were determined at the study center at baseline, after 4, 8 and 12 weeks. Primary endpoint was reduction of HbA1c, secondary endpoints reduction of weight and antidiabetic medication.

In the second part of the study type 2 diabetes patients are included in an open-label reistry and perform the lifestyle intervention with the stringent diet regime.

No evidence of a tumorigenic effect was seen when methyldopa was given for two years to mice at doses up to 1800 mg/kg/day or to rats at doses up to 240 mg/kg/day. (30 and 4 times the maximum recommended human dose in mice and rats, respectively, when compared on the basis of body weight; 2.5 and 0.6 times the maximum recommended human dose in mice and rats, respectively, when compared on the basis of body surface area; calculations assume a patient weight of 50 kg).

Methyldopa was not mutagenic in the Ames Test and did not increase chromosomal aberration or sister chromatid exchanges in Chinese hamster ovary cells. These studies were carried out both with and without exogenous metabolic activation. in vitro

Fertility was unaffected when methyldopa was given to male and female rats at 100 mg/kg/day (1.7 times the maximum daily human dose when compared on the basis of body weight; 0.2 times the maximum daily human dose when compared on the basis of body surface area). Methyldopa decreased sperm count, sperm motility, the number of late spermatids and the male fertility index when given to male rats at 200 and 400 mg/kg/day. (3.3 and 6.7 times the maximum daily human dose when compared on the basis of body weight; 0.5 and 1 times the maximum daily human dose when compared on the basis of body surface area).
The angiogenic inducer CCN1 (cysteine-rich 61, CYR61), a secreted matricellular protein of the CCN family, is a ligand of multiple integrins including alpha6beta1. Previous studies have shown that CCN1 interaction with integrin alpha6beta1 mediates adhesion of fibroblasts, endothelial cells, and smooth muscle cells, as well as migration of smooth muscle cells. Recently, we have reported that CCN1-induced tubule formation of unactivated endothelial cells is also mediated through integrin alpha6beta1. In this study, we demonstrate that human skin fibroblasts adhere specifically to the T1 sequence (GQKCIVQTTSWSQCSKS) within domain III of CCN1, and this process is blocked by anti-a6 and anti-b1 monoclonal antibodies. Alanine substitution mutagenesis of the T1 sequence further defines the sequence TTSWSQCSKS as the critical determinant for mediating alpha6beta1-dependent adhesion. Soluble T1 peptide specifically inhibits fibroblast adhesion to CCN1 in a dose-dependent manner. Furthermore, T1 also inhibits cell adhesion to other alpha6beta1 ligands including CCN2 (CTGF), CCN3 (NOV), and laminin, but not to ligands of other integrins. In addition, T1 specifically inhibits alpha6beta1-dependent tubule formation of unactivated endothelial cells in a CCN1-containing collagen gel matrix. To confirm that T1 binds integrin alpha6beta1 directly, we perform affinity chromatography and show that integrin alpha6beta1 is isolated from an octylglucoside extract of fibroblasts on T1-coupled Affi-gel. Taken together, these findings define the T1 sequence in CCN1 as a novel binding motif for integrin alpha6beta1, and form the basis for the development of peptide mimetics to examine the functional role of alpha6beta1 in angiogenesis.
Cyclodextrins can be coupled to biorecognition molecules such as antibodies. The cyclodextrins so coupled provide a cavity or complexation zone into which active agents such as labels, drugs and the like may be incorporated. The active agent forms a noncovalently bonded inclusion complex within the cavity of the cyclodextrin. It remains associated with the cyclodextrin and the coupled biorecognition molecule and thus can be delivered to the other half of the biospecific recognition pair. A process for producing these materials is also disclosed. The process includes the steps of activating a primary hydroxyl site on a cyclodextrin; linking a biorecognition molecule to the activated primary hydroxyl site on the cyclodextrin in either a direct covalent linkage or through a covalently linked spacer; and introducing a guest molecule (active agent) into the cavity of the derivatized cyclodextrin to form an inclusion complex.

The invention relates to a novel agent for the diagnosis and therapy of renal cell carcinoma and other renal tumors, for example, Wilms' tumor or other tumors not originating from the kidneys. The areas of applications of the invention include the field of medicine and the pharmaceutical industry. The aim of the invention is to provide novel forms of treatment, which are urgently required in the present-day processing state, as well as novel diagnostic agents for renal cell carcinoma. It was surprisingly discovered that the NBK protein, which is highly expressed in normal renal tissue, is not expressed at all or is only weakly expressed in the tumor tissue. The protein expression and the loss of NBK was examined in 80 renal cell carcinoma samples by using immunohistochemistry and mutation analysis. The inventive method for diagnosis is characterized in that the NBK protein concentration or the NBK-RNA quantity in the tissue is determined. The inventive agent for the therapy of the renal cell carcinoma and other renal tumors is characterized in that the NBK protein concentration in renal cell or in other tissues is increased and directly initiates the therapeutic effect in these cells.

Counseling including TB infection control practices and importance of diagnosis and treatment completion for TB cases will be provided to household members.
Patients with hematologic malignancies who relapse after allogeneic hematopoietic cell transplantation (HCT) have a poor prognosis. Although proceeding to subsequent HCT can provide potential for long-term survival, there are limited data to guide which patients are most likely to benefit and which HCT strategies are best in this heavily pretreated population. The goals of this study were to describe the clinical outcomes of subsequent HCT in pediatric patients with relapsed hematologic malignancies in a cohort enriched for haploidentical donors, and to evaluate the associations of patient-, disease-, and treatment-related factors with survival. We retrospectively evaluated patients who underwent a subsequent HCT for management of post-HCT relapse at a single institution between 2000 and 2021. Among 106 patients who underwent a second allogeneic HCT, the 1-year event-free survival (EFS) was 34% and 1-year overall survival (OS) was 46%, with a 5-year EFS of 26% and 5-year OS of 31%. Only disease-related factors were associated with outcome after second HCT-specifically, the interval between HCTs and the presence or absence of active disease at the time of HCT. In this cohort, patient- and treatment-related factors were not associated with differences in EFS or OS. Patients undergoing a third or fourth HCT (n = 13) had comparable survival outcomes to those undergoing a second HCT. Our experience highlights that a subsequent HCT has curative potential for a subset of patients who relapse after HCT, including those who undergo a subsequent HCT from a haploidentical donor. Although relapse and treatment-related toxicities remain major challenges, our study indicates that achieving complete remission prior to subsequent HCTs has the potential to further improve outcomes.
Catheter ablation has become an accepted first line therapy for paroxysmal atrial fibrillation (PAF), with pulmonary vein isolation (PVI) being the key element of ablation strategies. Catheter ablation of AF has been proven to be superior to antiarrhythmic drug (AAD) therapy regarding efficacy and improvement of survival in patients with heart failure. PVI has become a routine treatment procedure in recent decades especially for patients with symptomatic PAF. Recent research investigations have shown that AF recurrence still occurs in a significant number of patients after ablation. AF recurrence leads to a decrease in patients' quality of life and is related to an increased risk of cardiovascular events and mortality. As most arrhythmia recurrences take place within the first 3 months after the initial procedure, this time period is seen as a so-called "blanking period", in which ablation is not recommended, since up to 50 % of patients can become arrhythmia free in the long run. Ablation therapy, however, is less successful in patients suffering from long standing persistent AF, with a 20.3 % success rate after a single procedure and a 45 % success rate after multiple RFA procedures. Several scores have been established and validated to predict cardiac rhythm outcomes after catheter ablation. However, due to the lack of external validation of most of the scores, their efficacy in predicting recurrence of atrial fibrillation needs to be further evaluated in independent external studies.
Since the outbreak of Coronavirus Disease-2019 (COVID-19), the size of the infected population continues to expand, and the number of deaths due to the infection continues to climb. Massive vaccination has become the most critical measure to control the pandemic. Vaccination may cause side effects. Urgent vaccine development plus the characteristics of the coronavirus have caused the relatively more safety problems in COVID-19 vaccines than other classic vaccines and unavoidably raises more concerns among those who accept or consider to be vaccinated. Mulberry juice consists of a large amount of anthocyanin. The abnormally high interleukin-17A level is frequently seen in patients with inflammation status or diseases with inflammation features. Previous cell and animal studies have shown that some specific anthocyanins can reduce cyclooxygenase and nitrogen oxide, and the pharmacological effect of the major anthocyanin in mulberry juice imitates that of interleukin-17A antagonists. These features make mulberry juice a potential crude material for reducing inflammation and pain induced by COVID-19 vaccinations. The investigators propose a randomized control trial investigating the dose-response effects of three different volumes of mulberry juice on the incidence and severity of COVID-19 induced side effects and build up initial dose-response models for future reference in nutrition supplementation in COVID-19 vaccinations and improve public coordination of COVID-19 vaccinations.
The study treatments will be administered double-blind for 12 weeks, meaning that the patient and study personnel will not know the identity of the treatment. Approximately 75 patients will be randomized (patients are assigned to a treatment by a chance) in a 2:1 ratio to receive siltuximab plus best supportive care (BSC) (Group A) or placebo plus BSC (Group B). BSC includes RBC transfusion, antimicrobials, white blood cell (WBC) growth factors, and platelet transfusions. Patients who complete 12 weeks of treatment may qualify to receive siltuximab as open-label (identity of treatment will be known) treatment. Treatment may continue until death, unacceptable toxicity, withdrawal of consent, or the clinical cutoff (defined as 24 weeks after the last patient is randomized), whichever occurs first. The study will end approximately 36 weeks after the last patient is randomized. Patient safety will be monitored. Siltuximab and matching placebo will be supplied as a sterile, lyophilized formulation for reconstitution and intravenous (IV) infusion. Group A: siltuximab (15 mg/kg) administered as a 1-hour infusion every 4 weeks + BSC, or Group B: placebo administered as a 1-hour infusion every 4 weeks + BSC.
