Thoracolumbar fractures change the biomechanics of the spine. Load distribution causes kyphosis by the time. Treatment of posttraumatic kyphosis is still controversial. We reviewed the literature between 2010 and 2020 using a search with keywords “thoracolumbar fracture and kyphosis.” We removed osteoporotic fractures, ankylosing spondylitis fractures, non-English language papers, case reports, and low-quality case series. Up-to-date information on posttraumatic kyphosis management was reviewed to reach an agreement in a consensus meeting of the World Federation of Neurosurgical Societies (WFNS) Spine Committee. The first meeting was conducted in Peshawar in December 2019 with WFNS Spine Committee members’ presence and participation. The second meeting was a virtual meeting via the internet on June 12, 2020. We utilized the Delphi method to administer the questionnaire to preserve a high degree of validity. We summarized 42 papers on posttraumatic kyphosis. Surgical treatment of thoracolumbar kyphosis due to unstable burst fractures can be done via a posterior only approach. Less blood loss and reduced surgery time are the main advantages of posterior surgery. Kyphosis angle for surgical decision and fusion levels are controversial. However, global sagittal balance should be taken into consideration for the segment that has to be included. Adding an intermediate screw at the fractured level strengthens the construct.

[SWEET CORN EXTRACT AND COCONUT WATER EFFECT TO INDUCE GARLIC (Allium sativum L.) ADVENTIST SHOOTS BY IN-VITRO CULTURE]. Garlic (Allium sativum L.) is one of the horticultural plants used daily for various uses. This study aims to determine the best extract concentration of sweet corn and coconut water and its interaction for induction garlic Adventist shoots (Allium sativum L.) var. Lumbu Hijau. The study was conducted at the Biotechnology Laboratory, Agriculture Faculty, UPN ”Veteran” East Java, in February – April 2021. The experimental design used was a factorial completely randomized design (CRD). The first factor is four levels of extract of sweet corn concentration (0, 50, 100, and 150 g/L), while the second factor is four levels of coconut water concentration (0, 50, 100, and 150 mL/L). The results showed that the extract of sweet corn concentration-time treatment increased the growing adventist shoots percentage, adventist shoots number, and adventist shoots size. The section of sweet corn concentration of 150 g/L increased the rate of growing adventist shoots, adventist shoots number, and adventist shoots size. The treatment of coconut water concentration and its interaction with the extract of sweet corn concentration is still not able for induction garlic adventist shoots (Allium sativum L.) of the var. Lumbu Hijau.

Dental anxiety and dental phobia are still prevalent among adult individuals and should be considered a dental public health issue. Dental anxiety/phobia is often described as a vicious cycle where avoidance of dental care, poor oral health, and psychosocial effects are common features, often escalating over time. Treatment should include therapy for dental anxiety/phobia and oral diseases. This paper discusses aetiology, prevalence, and diagnosis of dental anxiety/phobia and, in detail, presents a conceptual treatment model at the Dental Fears Research and Treatment Center in Gothenburg, Sweden. In addition, based on systematic reviews, evidence-based treatment for dental anxiety is revealed including the interdisciplinary approach between psychology and dentistry.

Objective: Spironolactone (C24H32O4S), a potent mineralocorticoid receptor (MR) inhibitor, is a potassium-sparing diuretic that is traditionally used to treat fluid build-up in the body or for its anti-androgenic properties. This study is a double-blind, placebo-controlled, randomized clinical trial assessing the beneficial effects of spironolactone in addition to risperidone in improving negative symptoms of schizophrenia. Method: 40 patients with chronic schizophrenia, aged 18–60 years, were assigned to two groups: risperidone + spironolactone or risperidone + placebo. Risperidone was administered to both the spironolactone and placebo groups with a dose up to 6 mg/day throughout the trial. Spironolactone (C24H32O4S) was ordered 100 mg/day for the full 8-week course of the study. Patients were rated on the Positive and Negative Syndrome Scale (PANSS) at four time points: baseline, weeks two, four, and eight. The PANSS negative subscale score was the main objective. Results: PANSS negative, positive, and total scores showed significantly greater improvements in the spironolactone relative to the placebo group from baseline to the trial endpoint (P (Cohen’s d): 0.004 (0.96), 0.007 (0.90), and 0.042 (0.66), respectively). Similarly, ANOVA also presented significant time × treatment interaction effect for spironolactone on PANSS negative (F = 9.04; ηp2 = 0.19; df = 1.38; P = 0.002), positive (F = 3.43; ηp2 = 0.08; df = 2.72; P = 0.023), and total (F = 3.94; ηp2 = 0.09; df = 2.05; P = 0.022) scores. However, spironolactone did not cause significant decrease in the general psychiatric pathology score of PANSS. Conclusion: Our findings suggest the efficacy and safety of spironolactone as an adjunctive therapy to risperidone in improving the symptoms of schizophrenia.

Abstract Background Primary biliary cholangitis (PBC) may progress to cirrhosis and clinically significant portal hypertension (CSPH). This study assesses different features of CSPH and their distinct prognostic impact regarding decompensation and survival in patients with PBC. Methods Patients with PBC were identified during a database query of our digital patient reporting system. Results A total of 333 PBC patients (mean age 54.3 years, 86.8% females, median follow-up 5.8 years) were retrospectively assessed and 127 (38.1%) showed features of CSPH: 63 (18.9%) developed varices, 98 (29.4%) splenomegaly, 62 (18.6%) ascites and 20 (15.7%) experienced acute variceal bleeding. Splenomegaly, portosystemic collaterals and esophageal varices were associated with an increased 5-year (5Y) risk of decompensation (15.0%, 17.8% and 20.9%, respectively). Patients without advanced chronic liver disease (ACLD) had a similar 5Y-transplant free survival (TFS) (96.6%) compared to patients with compensated ACLD (cACLD) but without CSPH (96.9%). On the contrary, PBC patients with cACLD and CSPH (57.4%) or decompensated ACLD (dACLD) (36.4%) had significantly decreased 5Y survival rates. The combination of LSM < 15 kPa and platelets ≥ 150G/L indicated a negligible risk for decompensation (5Y 0.0%) and for mortality (5Y 0.0%). Overall, 44 (13.2%) patients died, with 18 (40.9%) deaths attributed to CSPH-related complications. Conclusion In PBC, features of CSPH may occur early and indicate an increased risk for subsequent decompensation and mortality. Hence, regular screening and on-time treatment for CSPH is crucial. Combining LSM and platelets serves as a valuable preliminary assessment, as LSM < 15 kPa and platelets ≥ 150G/L indicate an excellent long-term outcome.

Background  Hemophilia A is an X-linked genetic disorder caused by a mutation in the gene for factor VIII (FVIII) protein that reduces the ability of blood to clot. Clinical drug trials have shown the potential of adeno-associated virus (AAV) gene therapy as a one-time treatment for hemophilia A that can produce sustained high levels of FVIII. However, a gradual decline in protein levels has been observed in patients after 2-4 years. The hypothesis being tested in the Herzog Lab is that an interlinked immune and cellular stress response could be causing the loss of expression.     Methods  Two groups of Hemophilia A mice were administered AAV therapy, with one group receiving recurrent doses of Rapamycin. Blood samples were taken at weeks 4, 8, 12 and 14. Mice were euthanized at weeks 4, 8, and 14, and their livers were harvested. qPCR was used to measure AAV copy numbers and FVIII mRNA at 4, 8, and 14 weeks. Cryosections of mice livers from weeks 4, 8, and 14 were stained with antibodies for FVIII protein and CD8.    Results  qPCR showed roughly half as much AAV copy numbers in the rapamycin group at all time points, and little difference in FVIII mRNA between the groups. There was also a large decrease in AAV copy numbers and FVIII mRNA in both groups between 8 and 14 weeks. Immunohistochemistry showed less CD8 and more FVIII signal in mice treated with rapamycin.    Discussion  Experiments are currently being performed to investigate the decline in AAV copy numbers and mRNA between weeks 8 and 14. The immunohistochemistry data shows a relationship between increased FVIII protein levels and decreased cellular immune response but does not explain the gradual decline in FVIII. Further investigation into FVIII expression following AAV gene therapy could lead to an effective one-time treatment for hemophilia A.

Purpose - to estimate the disorder of spermatogenesis under conditions of experimentalchronic kidney disease (EChD).Material and methods. The study was carried out in two series of experiments on malemice with EChD, the model of which was created by immunizing animals with a kidneyhomogenate. The first series of experiments was devoted to the study of: sperm count(sperm concentration (mln / ml)) and the number of abnormal sperm forms; the ratio ofcells of different generations of spermatogenic epithelium (%) in the testes; pathways ofcell death of cells of the testes and epididymis (spermatocytes (primary) and spermatozoa).The fertile qualities of males were assessed in the second series of experiments, afterreplanting them to intact females. Pre- and post-implantation embryonic mortality andthe number of living fetuses per female mouse have been investigated. The research resultswere compared with the performance of animals in the control groups for each series.Results. No significant changes in the number of spermatozoa were found under EChDconditions (p> 0.05). An increase in the number of abnormal spermatozoa (22%) andthose with primary abnormalities (p <0.05) was found. Among the generations of testescells, a decrease in the number of spermatids and living spermatocytes (primary) (15%)was established, with an increase in the number of cells with apoptosis and necrosisamong them (p <0.05). The number of living cells of the epididymis (spermatozoa) alsodecreased (17.8%), with the growth of cells with apoptosis and necrosis among them (p<0.05). There was an increase in the pre- and post-implantation mortality of embryos (p<0.05); decrease in the number of living fetuses (p <0.05).Conclusions. Under conditions of four-time treatment with renal homogenate (EChD)there is a disorder of spermatogenesis in male mice. Experimental model of kidneydamage, proposed by us, can be useful for studying other aspects and consequences ofkidney pathology, and both for establishment of the features and detection of possiblepathogenetic links in the development of spermatogenesis disorder under conditions ofchronic kidney disease and search of the effective ways to correct it in future.

Abstract The article is devoted to the study of infrared drying of products in a reduced pressure chamber using the convection effect. With the use of drying, canning of fruits, vegetables, herbs and meat is achieved, which reduces not only the volume, but also the weight of the processed raw materials. The paper presents the main parameters of drying products online, such as relative humidity, pressure, radiation intensity of infrared lamps, drying temperature. The uniqueness of this unit in comparison with similar dryers is a one-time treatment of the product with infrared rays under reduced pressure, convection of air flows inside the drying chamber and full automation of the drying process of any product of plant and animal origin. Determination of parameters and modes of drying was carried out on products of plant origin. During the experimental part, bananas and apples were used. In experimental studies, products such as bell peppers, apples and bananas with various slicing thicknesses were used. The greatest drying effect was obtained with a drying product thickness of 5 mm, and the worst with a product thickness of 10 mm. For example, pepper has decreased in weight from 79.84 grams. up to 23.43 gr., which is his weight loss by 70.65%.

Peach is a putrescible fruit thus drastically restricting its postharvest storage life. In recent years, the application of 1-methylcyclopropene (1-MCP) and nitric oxide (NO) in postharvest fruit quality control has received considerable attention and investigative efforts due to the advantages of using relatively low concentrations and short-time treatment duration. In the present study, the effects of various 1-MCP and NO treatments on peach fruit (Prunus persica L. cv. Xiahui-8) stored at 25 °C were evaluated and compared. Results indicated that the combination treatment with both chemical agents (MN) was most effective in postponing peach ripening and preserving fruit quality, followed by 1-MCP and NO treatment alone. We also demonstrated that NO could delay fruit senescence mainly by stimulating antioxidant enzymes, while 1-MCP overly outperformed NO in the treatment of ‘Xiahui-8′ peach in slowing down respiration rate, inhibiting ethylene production, maintaining high firmness and reducing ROS content. NO treatment showed a greater influence on phenolic compounds than 1-MCP especially anthocyanins, flavanones and flavones according to LC/MS analysis. The phenolic change in MN group were highly associated to NO treatment. Through this study we provide informative physiological, biochemical and molecular evidence for the beneficial effects of the combined 1-MCP and NO treatment on peach fruit based on a functional synergy between these two chemical agents.

Abstract We leveraged the WF OAIC biorepository to measure a consensus-derived panel of blood-based biomarkers of aging and constructed a geroscience-guided biomarker index (TAME-BI), testing it for the first time in a clinical trial. We measured IL-6, TNF-α-receptor-I, growth differentiating factor-15, cystatin C, and N-terminal pro-B-type natriuretic peptide in a 20-week randomized trial of caloric restriction (CR), aerobic exercise (EX), CR+EX, or attention-control in 88 patients (67±5years) with heart failure with preserved ejection fraction (HFpEF). We calculated TAME-BI (analyte levels ranked, binned by quintile, and summed) and found a time×treatment interaction for improved TAME-BI with intervention (p≤0.05) and detected associations between change in TAME-BI and change in six-minute walk distance (r= -0.24), usual walk speed (r= -0.23), and left ventricular relative wall thickness (r= 0.31). In sum, CR+EX intervention improved TAME-BI and changes in TAME-BI were associated with changes in key functional measures in older HFpEF patients.
