ABSTRACT

The present study aims to investigate the mental state changes in patients with lumbar intervertebral disc damage after rehabilitation program using a self-administered questionnaire IRES-3. The study was conducted in the Specialized Hospitals for Rehabilitation – National Complex EAD, branches Hissar and Banite, Bulgaria. It included 124 patients – 34 men and 90 women, aged from 35 to 85 years. The questionnaire IRES-3, validated by the authors for the Bulgarian population, was used for measurement of the subjective evaluation of the rehabilitation effect. Measurements were performed at the beginning, end and three months after rehabilitation (RH). The subjective evaluation of the patients’ mental state included the following scales: depression, fear, exhaustion of vitality, self-confidence and symptom: cognitive functioning. We found a statistically significant improvement of the scores three months after rehabilitation compared to the beginning of rehabilitation for all scales. The only exceptions are the scales exhaustion of vitality and symptom: cognitive functioning. We found a statistically significant improvement of the self-rated mental state after performed rehabilitation in patients with chronic diseases.

ABSTRACT

Cancer vaccine contributing to the success of the treatment and prevention of tumors has attracted a huge attention as a strategy for tumor immunotherapy in recent years. A major challenge of cancer vaccine is to target cytosols of dendritic cells (DCs) in the lymph nodes (LNs) to enhance efficiency of antigen cross-presentation, which elicits high levels of cytotoxic T-lymphocytes to destruct tumor cells. Here, we address this issue by conjugating ovalbumin (OVA) to PEG-PCL using disulfide bond (-ss-), and the degradable pH-responsive polymer-PEI-PCL as delivery carrier. In addition, the mol ratio of PEG-PCL to PEI-PCL in the mixed micelles was tailored to deliver the OVA to LNs. Subsequently, CpG ODN₁₈₂₆, a TLR-9 agonist, was further introduced into a mixed micelle of 30 nm or less as a unique tumor vaccine. Importantly, the results demonstrated the mixed micelles with 1:1 mol of PCL-PEG and PCL-PEI can effectively migrate to distal LNs where antigen were efficiently captured by DCs, meanwhile, OVA was modified to the surface of mixed micelles via disulfide bonds (-ss-) for promotion efficiency of antigen cross-presentation. More surprisingly, combination of tumor vaccine with anti-PD-1, the therapy of ectopic melanoma (B16-OVA) and lung metastasis melanoma (B16-OVA) is excellent therapeutic effect. Taken together, our works offers a novel strategy for the cytosol delivery of antigens to achieve potent cancer immunotherapy.

ABSTRACT

Microbial cell culture is one of the most commonly performed protocols for synthetic biology, and laboratories are increasingly using 96-well plates and laboratory automation systems for cell culture. Here, we describe a method for reproducible microbial culture using laboratory automation systems, including automated liquid handling, automated plate sealing and de-sealing, automated incubation and measurement of growing cultures. We discuss the key considerations that, in our experience, are important for reproducibility and present statistical analyses of data from 150 automated microbial growth experiments performed over 27 months using our automated method.

ABSTRACT

OBJECTIVE: Proximal humerus fractures became one of the most prevalent upper extremity fractures during recent decades. The use of scoring systems has been taken under consideration to estimate the surveillance, prognosis, and post-operative outcomes. During this study, we investigated the outcome measure of proximal humerus fracture treated by open reduction and internal fixation (ORIF) with plate based on oxford shoulder score (OSS). Furthermore, we tried to propose a new classification system for OSS that could be of prognostic value.

METHODS: Patients with proximal humerus fracture treated by open reduction enrolled in the study. Persian version of the OSS was completed by the patients. Data were analyzed using SPSS-22.

RESULTS: Forty-four patients including 24 women and 20 men were assessed. The mean age was 54.61 (SD ± 19.371) years. The use of a spoon and fork at the same time had the best score and hanging the clothes up in a wardrobe with the operated hand had the worst score in the questionnaire. Comparison of OSS and number of physiotherapy session showed that patients with best outcome had least number of physiotherapy’s session, but it was not statistically significant.

CONCLUSION: OSS is useful to evaluate the function of the traumatized shoulder. We suggest classifying the OSS score into three range groups, good (total score 12-28), moderate (total score 29-44), and bad (total scores 45-60).

ABSTRACT

<b>Background and Objective:</b> Studying the population dynamic of the invasive terrestrial snails as agricultural pests, is essential for designing pest control program to reduce the economic losses to commercial field crops, vegetables and fruits. The population dynamic had been estimated for the three terrestrial snails <i>Theba pisana </i>(Müller, 1774) (Helicidae), <i>Eobania vermiculata </i>(Müller, 1774) (Helicidae) and <i>Monacha obstructa</i> (Pfeiffer, 1842) (Hygromiidae) on orange, apple and mango trees in horticultural fields in two locations. These locations are Nobaria City, Beheira Governorate and Mansouria Village, Giza Governorate. This study carried out during the two consecutive activity seasons September, 2018/August, 2019 and September, 2019/August, 2020. <b>Materials and Methods:</b> The population dynamic, incidence and infestation level of terrestrial snails had been recorded on economic host plants such as fruit trees and other field crops and vegetables. The correlations between climatic factors and the population density of land snails were interpreted by statistical analysis for the two seasons. <b>Results:</b> The population density of terrestrial snails increased gradually after winter to reach its maximum density during spring, while the lowest density was recorded in August. The incidence and infestation level of terrestrial snails varied according to the host plant, climatic factors and locality. <i>Eobania vermiculata</i> were the dominant land snail species in Beheira, while <i>Monacha obstructa</i> infested the majority of the examined fruit trees in Giza. <b>Conclusion:</b> Determining the activity and inactivity periods of land snails through the two seasons and their population dynamic will assist in designing effective control management program to decrease the number of pest and the economic losses of agricultural products.

ABSTRACT

&lt;b&gt;Background and Objective:&lt;/b&gt; Immune complexes and pro-inflammatory cytokines deduced from communicable diseases have been manifested to induce pro coagulopathy and tissue factor (TF) assertion in macrophages and the endothelial cells that remain at critical risk in tuberculosis (TB) patients. The current study was carried out among Sudanese patients with Pulmonary tuberculosis aimed to determine the long-term impacts of Tb infection on the coagulation cascade. &lt;b&gt;Materials and Methods:&lt;/b&gt; A cross-sectional study was conducted among 30 patients who are already diagnosed with tuberculosis compared with the control group. Pulmonary Tuberculosis diagnosis of cases was emphasized in accordance with clinical examination, chest X-ray and positive Ziehl-Neelsen (ZN) smear. The questionnaire was used for the collection of demographic and baseline data. About 2.5 mL of venous blood was collected in trisodium citrate containers and 2.5 mL of blood was collected in EDTA container. SPSS version 21 statistical software was used for statistical analysis. &lt;b&gt;Results:&lt;/b&gt; PLT count showed a significant difference (p = 0.03) with a mean (329.20×10&lt;sup&gt;3&lt;/sup&gt; and 287.60×10&lt;sup&gt;3&lt;/sup&gt; μL&lt;sup&gt;&lt;/sup&gt;&lt;sup&gt;1&lt;/sup&gt;) among patients and control, respectively. APPT shows a significant difference (p = 0.00), Mean of PLT decreased as the disease progressed (336.20±36.02, 345.43±16.02, 511.04±42.02) showed a significant correlation between PLT count of test and duration of disease (p = 0.00). Additionally, a significant correlation between PLT count, MPV and APTT and the status of the patient’s drug resistance was revealed (p&lt;u&gt;<&lt;/u&gt;0.02, 0.01 and 0.02). &lt;b&gt;Conclusion:&lt;/b&gt; There is a significant alteration in coagulation parameters (PT, APTT and platelets count) among Sudanese pulmonary tuberculosis patients, which may indicate a feature of a hypercoagulable state.

ABSTRACT

&lt;b&gt;Background and Objective:&lt;/b&gt; Smokers are poorly protected against pathogens. Many studies have focused on the concentrations of complement components in comparison to smokers while ignoring the practical sequencing of complement components. There are numerous methods for estimating haemolytic activity (CH50%), all of which need a large number of samples and dilution, in addition to a typically expensive test kit. This novel study attempts to use statistical analysis and use the non-linear regression ‘power equation’ to extract the CH50% by using 5 serum dilutions only. &lt;b&gt;Materials and Methods:&lt;/b&gt; The power equation can multiply the five practical dilutions into hundreds of mathematical loops within the sample range. The (CH50%) value is highly accurate for both the study and comparison sample and was evaluated in11 smokers. &lt;b&gt;Results:&lt;/b&gt; The results were contrasted with a control composed of 11 individuals, matched by age and sex. The power equation showed a 6.48% significant reduction in (CH50%) in smokers compared with non-smokers, where a 17.54% reduction was observed. &lt;b&gt;Conclusion:&lt;/b&gt; The current study suggests a decrease in the function of the classical complement pathway (CH50%) in smokers. On the other hand, the study provided a new statistical pattern, linking the practical values with default values within the range of dilution and formulating an equation that could be used to extract the value of CH50% with high accuracy.
