Abstract
Background There has been significant international interest in heterologous prime-boost COVID-19 vaccination. However, it is linked with different intensity and frequency of adverse events. This study aimed to assess the safety of ChAdOx1-S and BNT162b2 vaccines when given as heterologous prime-boost vaccination in Saudi Arabia. Methods A cross-sectional study was conducted during the period October 2021 to March 2022. The study included two groups of people based on the type of vaccination regimen. The first group (heterologous) was subjected to different prime-boost vaccination schedules irrespective of the prime and boost vaccine types. The second group included people vaccinated with the same type of COVID-19 vaccine (homologous). Results The overall sample included 334 participants. Those included in the heterologous group were at about 1.5 fold -increased risk for developing local and systemic adverse events compared to the homologous group. Fever, headache, and vomiting were significantly more frequent among the heterologous group compared to the homologous group (p-value<0.05). In both groups, more than half of the recorded adverse events were mild/moderate in severity. Conclusion Heterologous prime-post vaccination is associated with a slightly increased risk for the development of local and systemic adverse events compared to the homologous regimen. However, most of these adverse events are mild/moderate in nature and recede within two days with no serious adverse events documented.

Abstract
What is already known about this topic? Although a third coronavirus disease 2019 (COVID-19) vaccination (booster) dose is highly recommended for diabetic patients, the vaccination behaviors and related adverse events are unclear among diabetic patients with a COVID-19 booster dose. What is added by this report? Diabetic patients with higher postprandial blood glucose, worrying about the safety of the booster dose were less likely to get the vaccine. While having positive attitudes towards COVID-19 booster vaccination, trusting the health professionals' advice on vaccination, diabetic patients were more likely to get the booster vaccine. Furthermore, the prevalence of adverse events was not significantly different between the homologous and heterologous boosting groups. What are the implications for public health practice? Effective measures should be taken to promote the COVID-19 booster dose uptake among diabetic patients. Health professionals should educate Chinese diabetic patients about the safety and efficacy of booster doses and continue to increase the COVID-19 booster dose vaccination coverage.

Abstract
The establishment and maintenance of the symbiosis between a cnidarian host and its dinoflagellate symbionts is central to the success of coral reefs. To explore the metabolite production underlying this symbiosis, we focused on a group of low weight secondary metabolites, biogenic volatile organic compounds (BVOCs). BVOCs are released from an organism or environment, and can be collected in the gas phase, allowing non-invasive analysis of an organism's metabolism (i.e. 'volatilomics'). We characterised volatile profiles of the sea anemone Exaiptasia diaphana ('Aiptasia'), a model system for cnidarian-dinoflagellate symbiosis, using comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry. We compared volatile profiles between: 1) symbiotic anemones containing their native symbiont, Breviolum minutum; 2) aposymbiotic anemones; and 3) cultured isolates of B. minutum. Overall, 152 BVOCs were detected, and classified into 14 groups based on their chemical structure, the most numerous groups being alkanes and aromatic compounds. A total of 53 BVOCs were differentially abundant between aposymbiotic anemones and B. minutum cultures; 13 between aposymbiotic and symbiotic anemones; and 60 between symbiotic anemones and cultures of B. minutum. More BVOCs were differentially abundant between cultured and symbiotic dinoflagellates than between aposymbiotic and symbiotic anemones, suggesting that symbiosis may modify symbiont physiology more than host physiology. This is the first volatilome analysis of the Aiptasia model system and provides a foundation from which to explore how BVOC production is perturbed under environmental stress, and ultimately the role they play in this important symbiosis.

Abstract
Oncogenetic testing is now part of standard management in high grade ovarian cancer, including at least mutational status of BRCA1/BRCA2 genes. If necessary, tumor genetic testing is followed by constitutional testing to either confirm the constitutional origin of variants identified in BRCA1/2 genes or detect variants in other predisposition genes. The whole process including prescription of tumoral testing, retrieval of analysis report and communication of results must be formalized, as well as information on possible consequences of the results for the patient and her family. Tumor material must meet criteria of size and cellularity to allow high-quality analysis. These samples are processed during the preanalytical phase with two major steps : time of cold ischemia and fixation. Only pathogenic (Class V) and likely pathogenic (Class IV) variants shown in tumor tissue are mentioned in the report. Currently, only BRCA1 and BRCA2 genes are routinely studied but, in the future, analysis will be extended to other genes involved in homologous recombination repair. In patients without BRCA mutation, other biomarkers reflecting sensitivity to PARP inhibitors, such as HRD scores (homologous recombination deficiency) that appeared recently, will have to be implemented in routine practice in order to better select patients for these treatments and choose optimal therapy.

Abstract
BACKGROUND Pathogenesis-related (PR) proteins are induced in response to biotic and abiotic stresses. Some plant proteins, including Mal d 1, Mal d 2, and Mal d 3 in apple, are allergens. In this study, the effects of Erwinia amylovora infection of two apple cultivars, Red and Golden Delicious, on the expression of PR proteins homologous to Mal d 1, 2, and 3 were investigated. METHODS In natural conditions trees with or without disease symptoms were sampled. In addition, seeds of the cultivars were grown in a greenhouse and seedlings were examined in three groups: 1) those inoculated by E. amylovora, 2) those inoculated by sterilized distilled water, and 3) uninoculated. Real-time PCR was used to determine expression of the Mal d 1, 2, and 3 genes (Mal d 1, 2, and 3) in infected and uninfected samples. Statistical analyses were performed using SPSS and graphs were produced by Excel. P values < 0.05 were considered significant. RESULTS The analysis of variance showed that in natural conditions the effect of infection on the mean relative expression of Mal d 2 and 3 was significant, and more so in Red than in Golden Delicious. The analysis of variance of the greenhouse samples showed that the effect of infection on the mean relative expression of Mal d 1, 2, and 3 in both cultivars was significant. CONCLUSION Our results suggest that Mal d 2 is more related to plant defense than Mal d 1 or Mal d 3, and is more highly expressed in E. amylovora-resistant than in E. amylovora-sensitive cultivars.

Abstract
BACKGROUND AND OBJECTIVES Patients who have failed a transplant are at increased risk of repeat transplant failure. We determined access to transplantation and transplant outcomes in patients with and without a history of transplant failure. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In this observational study of national data, the proportion of waitlisted patients and deceased donor transplant recipients with transplant failure was determined before and after the new kidney allocation system. Among patients initiating maintenance dialysis between May 1995 and December 2014, the likelihood of deceased donor transplantation was determined in patients with (n=27,459) and without (n=1,426,677) a history of transplant failure. Among transplant recipients, allograft survival, the duration of additional kidney replacement therapy required within 10 years of transplantation, and the association of transplantation versus dialysis with mortality was determined in patients with and without a history of transplant failure. RESULTS The proportion of waitlist candidates (mean 14%) and transplant recipients (mean 12%) with transplant failure did not increase after the new kidney allocation system. Among patients initiating maintenance dialysis, transplant-failure patients had a higher likelihood of transplantation (hazard ratio [HR], 1.16; 95% confidence interval [95% CI], 1.12 to 1.20; P<0.001). Among transplant recipients, transplant-failure patients had a higher likelihood of death-censored transplant failure (HR, 1.44; 95% CI, 1.34 to 1.54; P<0.001) and a greater need for additional kidney replacement therapy required within 10 years after transplantation (mean, 9.0; 95% CI, 5.4 to 12.6 versus mean, 2.1; 95% CI, 1.5 to 2.7 months). The association of transplantation versus dialysis with mortality was clinically similar in waitlisted patients with (HR, 0.32; 95% CI, 0.29 to 0.35; P<0.001) and without transplant failure (HR, 0.40; 95% CI, 0.39 to 0.41; P<0.001). CONCLUSIONS Transplant-failure patients initiating maintenance dialysis have a higher likelihood of transplantation than transplant-naïve patients. Despite inferior death-censored transplant survival, transplantation was associated with a similar reduction in the risk of death compared with treatment with dialysis in patients with and without a prior history of transplant failure.

Abstract
Several studies have been performed to determine specific antigens for the diagnosis of tapeworms. One of these antigens is Tso31, which is used to differentiate Taenia solium and Taenia saginata in human feces. The aim of the present work was the molecular characterization of this protein in different tapeworm specimens collected in Peru: T. omisa (n = 6), T. hydatigena (n = 7), T. taeniaeformis (n = 4), T. pisiformes (n = 1), T. multiceps (n = 7), and T. solium (n = 10). Total DNA was extracted from each proglottid using a commercial DNA kit for tissue. A nested PCR was used to amplify a fragment of the previously described oncosphere-specific protein Tso31 gene. The nested PCR products were analyzed by 1.5% agarose gel electrophoresis and visualized after ethidium bromide staining. All nested PCR-positive products were sequenced and their sequences were compared. Of all the tapeworms analyzed, only T. solium and T. multiceps amplified the Tso31 gene. All sequences were identical for each species. Our T. solium Tso31 showed 100% similarity when compared with published GenBank sequences. The difference between T. solium and T. multiceps Tso31 samples was 8.1%. In conclusion, our results show that the tsol31 gene is not exclusive to T. solium.

Abstract
In order to develop ELISA for medroxyprogesterone acetate, medroxyprogesterone acetate-3-carboxymethyloxime (MPA-3-CMO) was coupled to bovine serum albumin (BSA) for immunogen preparation and to horseradish peroxidase (HRP) for enzyme conjugate preparation by N-hydroxysuccinimide mediated carbodiimide reaction. The immunogen was used to raise the antiserum in New Zealand white rabbit. The immunoreactivity of MPA-3-CMO-BSA-antibody and MPA-3-CMO-HRP enzyme conjugate was checked by checkerboard assay. The MPA-3-CMO-HRP enzyme conjugate and MPA-3-CMO-BSA-antibody were used for further development, standardization and validation of the assay. Sensitivity, ED50 and affinity of the assay were found to be 0.114 ng/mL, 2.75 ng/mL and 9.9 × 10⁻⁸ L/mol respectively. The % cross-reaction of analogous steroids with MPA-3-CMO-BSA-antibody was less than 0.025%. The recovery of the exogenously spiked MPA serum pools were in the range of 96.83-105.47%. The intra- and inter-assay coefficients of variation was less than 7.02%. The correlation coefficient of the serum level of MPA measured by the developed assay with the commercially available kit was found to be 0.95 (n = 37). This developed ELISA was further validated by measuring serum level of MPA in rat after administering them different doses of MPA intramuscularly.

Abstract
OBJECTIVE To examine significance of sarcoma dominance (SD) patterns in uterine carcinosarcoma (UCS). METHODS This is a secondary analysis of multicenter retrospective study examining women with stages I-IV UCS who underwent primary surgery. SD was defined as >50% of sarcoma component in uterine tumor. SD patterns were grouped as homologous sarcoma without SD (homo/non-dominance, n = 351), heterologous sarcoma without SD (hetero/non-dominance, n = 174), homologous sarcoma with SD (homo/dominance, n = 175), and heterologous sarcoma with SD (hetero/dominance, n = 189), and correlated to tumor characteristics and survival. RESULTS SD patterns were significantly associated with age, body habitus, carcinoma type, tumor size, depth of myometrial invasion, and nodal metastasis (all, P < 0.05). On univariate analysis, SD was associated with decreased progression-free survival (PFS) and cause-specific survival (CSS) in homologous cases (both, P < 0.05) but not in heterologous cases. On multivariate models, both homologous and heterologous SD patterns remained independent prognostic factors for decreased PFS (adjusted-hazard ratio [HR] ranges: homo/dominance 1.35-1.69, and hetero/dominance 1.47-1.64) and CSS (adjusted-HR ranges: 1.52-1.84 and 1.66-1.81, respectively) compared to homo/non-dominance (all, P < 0.05). Among stage I-III disease, when tumors had SD, adding radiotherapy to chemotherapy was significantly associated with improved PFS (adjusted-HR: homo/dominance 0.49, and hetero/dominance 0.45) and CSS (0.36 and 0.31, respectively) compared to chemotherapy alone (all, P < 0.05); contrary, this association was not observed with absence of SD (all, P > 0.05). CONCLUSION In UCS, SD impacts survival in homologous but not in heterologous type. Regardless of sarcoma types, SD was associated with decreased survival in UCS; adding radiotherapy to chemotherapy may be an effective postoperative strategy.

Abstract
The essential bacteriophage T7-encoded single-stranded DNA binding protein is the nexus of T7 DNA metabolism. Multiple layers of macromolecular interactions mediate its function in replication, recombination, repair, and the maturation of viral genomes. In addition to binding ssDNA, the protein binds to DNA polymerase and DNA helicase, regulating their activities. The protein displays potent homologous DNA annealing activity, underscoring its role in recombination.

Abstract
Bioligands (BL) present in plant and microbes are primarily responsible for their use in metal decontamination. Both primary (proteins and amino acid) and secondary (proliferated) response in the form of BL is possible in plants and microbes toward metal bioremediation. Structure of these BL have specific requirement for preferential binding towards a particular metal in biomass. The aim of this review is to explore various templates from BL (as metal host) for the metal detoxification/decontamination and associated bioremediation. Mechanistic explanation for bioremediation may involve the various processes like: (i) electron transfer; (ii) translocation; and (iii) coordination number variation. HSAB (hard and soft acid and base) concept can act as guiding principle for many such processes. It is possible to investigate various structural homolog of BL (similar to secondary response in living stage) for the possible improvement in bioremediation process.

Abstract
OBJECTIVE Description of a new surgical technique for treating the shoulders of patients with sequelae of obstetric paralysis. Preliminary analysis on the results obtained from this technique. METHODS Five consecutive patients underwent the proposed surgical procedure, consisting of arthroscopic anterior joint release followed by transfer of the latissimus dorsi tendon (elongated and reinforced with a homologous tendon graft) to the posterosuperior portion of the greater tubercle, using a single deltopectoral approach. All the patients were reevaluated after a minimum postoperative period of twelve months. The functional assessment was based on the range of motion and the modified Mallet classification system. Statistical analyses were not possible because of the small sample. RESULTS Overall, passive and active lateral rotations increased, while medial rotation decreased. The other movements (elevation, capacity to place a hand in the mouth and capacity to place a hand behind the neck) had less consistent evolution. The mean modified Mallet score improved by 4.2 points (from 11.4 to 15.6). CONCLUSION The latissimus dorsi tendon can be transferred to the posterosuperior portion of the greater tubercle through a single deltopectoral approach when elongated and reinforced with a homologous tendinous graft.

Abstract
Recombination hotspots are the regions within the genome where the rate, and the frequency of recombination are optimum with a size varying from 1 to 2kb. The recombination event is mediated by the double-stranded break formation, guided by the combined enzymatic action of DNA topoisomerase and Spo 11 endonuclease. These regions are distributed non-uniformly throughout the human genome and cause distortions in the genetic map. Numerous lines of evidence suggest that the number of hotspots known in humans has increased manifold in recent years. A few facts about the hotspot evolutions were also put forward, indicating the differences in the hotspot position between chimpanzees and humans. In mice, recombination hot spots were found to be clustered within the major histocompatibility complex (MHC) region. Several models, that help explain meiotic recombination has been proposed. Moreover, scientists also developed some computational tools to locate the hotspot position and estimate their recombination rate in humans is of great interest to population and medical geneticists. Here we reviewed the molecular mechanisms, models and in silico prediction techniques of hot spot residues.

Abstract
The goals of this chapter are to provide an introduction into the variety of animal models available for studying traumatic brain injury (TBI) and to provide a concise systematic review of the general materials and methods involved in each model. Materials and methods were obtained from a literature search of relevant peer-reviewed articles. Strengths and weaknesses of each animal choice were presented to include relative cost, anatomical and physiological features, and mechanism of injury desired. Further, a variety of homologous, isomorphic/induced, and predictive animal models were defined, described, and compared with respect to their relative ease of use, characteristics, range, adjustability (e.g., amplitude, duration, mass/size, velocity, and pressure), and rough order of magnitude cost. Just as the primary mechanism of action of TBI is limitless, so are the animal models available to study TBI. With such a wide variety of available animals, types of injury models, along with the research needs, there exists no single "gold standard" model of TBI rendering cross-comparison of data extremely difficult. Therefore, this chapter reflects a representative sampling of the TBI animal models available and is not an exhaustive comparison of every possible model and associated parameters. Throughout this chapter, special considerations for animal choice and TBI animal model classification are discussed. Criteria central to choosing appropriate animal models of TBI include ethics, funding, complexity (ease of use, safety, and controlled access requirements), type of model, model characteristics, and range of control (scope).

Abstract
Multi-analyte immunoassays have attracted increasing attention due to their short assay times, low sample consumption, and reduced detection costs per assay. In this work, we describe a homologous and high-throughput multi-wavelength fluorescence polarization immunoassay (MWFPIA) for the multiplexed detection of mycotoxins. Three typical Fusarium mycotoxins, deoxynivalenol (DON), T-2 toxin and fumonisin B1 (FB1), were labeled with different dyes. Tracers and specific monoclonal antibodies (mAbs) were employed in the MWFPIA to simultaneously detect the three mycotoxins. Under optimal conditions, the limits of detection using MWFPIA were 242.0 μg kg(-1) for DON, 17.8 μg kg(-1) for T-2 toxin and 331.5 μg kg(-1) for FB1, providing sufficient sensitivity to meet the action levels of these three contaminants in maize as set by the European Union. The use of a methanol/water (2:3, v/v) mixture for sample pretreatment allowed recoveries ranging from 76.5-106.3%, with coefficients of variation less than 21.7%. The total time of analysis, including sample preparation, was less than 30 min. Twenty naturally contaminated maize samples were tested using MWFPIA and HPLC-MS/MS, with correlation coefficients (R(2)) of 0.97 for DON and 0.99 for FB1. By changing the targets of interest, homologous MWFPIA, a method with high sensitivity, a simple procedure and a short analysis time, can easily be extended to other chemical contaminants. Thus, MWFPIA represents a versatile strategy for food safety analysis.

Abstract
OBJECTIVE The purpose of this study was to evaluate the efficacy and safety of intraoperative autologous blood transfusion during laparotomy for hemoperitoneum in ectopic pregnancy and also safety of homologous blood transfusion along with autologous blood transfusion. METHOD Fresh blood, from peritoneal cavity, was collected for autotransfusion in sterile dish, filtered through eight layers of sterile gauze pieces, and collected in a sterile bowl. The collected blood was transferred into blood infusion bag containing citrate phosphate dextrose adenine solution in the proportion of five parts of blood to one part of citrate solution. RESULTS Mean volume of autologous blood transfused in patients without homologous transfusion was 573 ± 328. Mean preoperative hemoglobin was 4.95 ± 1.5, and postoperative hemoglobin was 6.85 ± 1.3. Hence, rise in hemoglobin was 1.9 g%. Autologous blood volume transfused in 29 patients (who required homologous blood transfusion) was 488 ± 216. Preoperative hemoglobin was 4.35 ± 1.94. The result was compared with other studies. CONCLUSION Intraoperative autologous blood transfusion enabled the performance of laparotomy in hemodynamically unstable ectopic pregnancy patients without availability of homologous blood transfusion. Homologous blood transfusion is compatible with autologous blood transfusion.

Abstract
Myelofibrosis (MF) is a manifestation of several disorders of hematopoiesis, collectively referred to as myeloproliferative neoplasms. Allogeneic hematopoietic stem cell transplantation (ASCT) is the only therapy with proven curative potential. However, most patients with MF are in their 6th or 7th decade of life, and only some of these patients have been considered suitable transplantation candidates. The development of reduced-intensity conditioning regimens with limited toxicity has allowed clinicians to offer ASCT to a growing number of older patients. The availability of Janus Kinase (JAK) 1/2 inhibitors allows clinicians to provide symptom relief and improved quality of life for MF patients. These drugs may also affect the decision regarding, in particular, the timing of ASCT. Future studies need to address the role of JAK1/2 inhibitors in patients who are transplantation candidates and determine their role before and, possibly, after transplantation. The identification of indications for the use of JAK1/2 inhibitors in the context of transplantation may lead to new therapeutic strategies for patients with MF.

Abstract
We are moving into a new era of stem cell research where many possibilities for treatment of degenerative, chronic and/or fatal diseases and injuries are becoming primed for clinical trial. These reports have led millions of people worldwide to hope that regenerative medicine is about to revolutionise biomedicine: either through transplantation of cells grown in the laboratory, or by finding ways to stimulate a patient’s intrinsic stem cells to repair diseased and damaged organs. While major contributions of stem cells to drug discovery, safety and efficacy testing, as well as modelling ‘diseases in a dish’ are also expected, it is the in vivo use of stem cells that has captured the general public’s attention. However, public misconceptions of stem cell potential and applications can leave patients vulnerable to the influences of profit driven entities selling unproven treatments without solid scientific basis or appropriate clinical testing or follow up. This review provides a brief history of stem cell clinical translation together with an overview of the properties, potential, and current clinical application of various stem cell types. In doing so it presents a clearer picture of the inherent risks and opportunities associated with stem cell research translation, and thus offers a framework to help realise invested expectations more quickly, safely and effectively.
