There are several components that constitute the project management process, such as Quality Management (QM) and Control Systems, along with "Time, Cost, and Performance Management", that are integral parts of the project management process. During the course of the project, the project work has also been monitored for quality, as with any normal production or manufacturing operation, and it is important that improvements to the project work are also made as the project. It is important to understand that a project is composed of a number of sequential and concurrent tasks and activities that aim to achieve specific inputs and outputs by the end of the project.inputs and outputs. In order to ensure the work is completed correctly, the tasks and activities are carried out successfully as per plan, and the end product meets the requirements of the client or sponsor in the project, it is extremely important that these inputs and outputs are managed and controlled correctly. The outcome of flawed work on one activity/task would have a detrimental effect on subsequent activities, and subsequent activities would have to be reworked, which would result in a delay in the project, an increase in costs, and a threat to its success.

Employing the microhydration model that involves two to five explicit water molecules, two plausible dissociative hydrolysis pathways of 2’,3’-didehydro-2’,3’-dideoxyuridine (d4U), α-path with configuration-inversion and β-path with configuration-retention, have been investigated by M06-2X(CPCM)/6-31++G(d,p) method. Using this model, inclusion of three explicit water molecules (n=3) is shown to be the smallest system that gives the minimal activation free energy for α-path and β-path. Our results suggest that the glycoside cleavage is the RDS, and α-path is more favorable kinetically than β-path. Whereas β-path with exergonic formation of β-dihydrofuran-like sugar with keto pyrimidine complex possesses thermodynamic preference over α-path, where the formation of α-dihydrofuran-like sugar with enol pyrimidine complex is endergonic. The free energy barriers of RDSs for d4U (24.8 kcal mol-1) and d4T (27.3 kcal mol-1) suggest that the glycosidic bond in d4T is more stable than that in d4U. The relative lower stability of d4U is probably an important factor for less antiviral activity of d4U. The small free energy barrier differences of ~1 kcal mol-1 for β-path over α-path, and the reaction free energy differences of ~ -12 kcal mol-1 for β-path lower than α-path in d4T and d4U suggest a competitive β-path in pyrimidine d4Ns. The higher free energy barriers of RDSs in ddU (27.6 kcal mol-1) and ddT (29.0 kcal mol-1) indicate that the saturated sugar moiety increases the stability of glycosidic bond in contrast to the unsaturated counter parts in d4U and d4T. NBO analysis also shows the kinetic preference of α-path over β-path. Our results provide an exploration for the less antiviral activity of d4U and the influence of saturated ribose on the glycosidic bond stability of pyrimidine d4Ns.

β-Glucosidase is validated as an elicitor for early immune responses in plants and it was detected in the salivary glands of Frankliniella occidentalis in previous research. Seven differentially expressed genes encoding β-Glucosidase were obtained by comparing the transcriptomes of F. occidentalis adults grown under two different CO 2 concentrations (800 ppm vs. 400 ppm), which might be associated with the differences in the interaction between F. occidentalis adults and its host plant, Phaseolus vulgaris under different CO 2 levels. To verify this speculation, changes in defense responses based on the production and elimination of reactive oxygen species (ROS) in P. vulgaris leaves treated with three levels of β-Glucosidase activity under ambient CO 2 (aCO 2) and elevated CO 2 (eCO 2) were measured in this study. The results showed that both leaves infested with thrips and those sprayed with the pure β-Glucosidase solution showed significant increases in ROS levels under aCO 2 and eCO 2, and the activities of antioxidant enzymes including superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were increased correspondingly, while in leaves infested with FoβGlu-1-silenced thrips, the ROS levels and activities of these enzymes did not change significantly during the first 12 hours of injury regardless of CO 2 level. Besides, significantly higher levels of ROS and lower activities of SOD, POD and CAT in injured leaves under eCO 2 compared to aCO 2 were noticed, which would negatively affect P. vulgaris leaves and facilitate thrips damage.

We performed fetoscopic laser photocoagulation at 25+1 weeks gestation successfully. But ultrasound showed apparent separation of the chorioangioma from the placenta at 32+2 weeks gestation. An urgent cesarean section was performed with the delivery of a healthy female infant. To date, there have been no reports of similar cases.

An 88-year-old man ingested coins accidentally and developed mediastinitis and septic shock. Esophageal injuries by sharped-shape foreign bodies are often reported, but esophageal perforation by round coins is rare. Even rounded-shape foreign bodies that are unlikely to injure esophagus may lead to severe outcomes.

In this account we report an implementation of the quantum trajectory-guided adaptive Gaussian (QTAG) method in a modular open-source Libra package for quantum dynamics calculations. The QTAG method is based on a representation of wavefunctions in terms of a quantum trajectory-guided adaptable Gaussians basis and is generalized for time-propagation on multiple coupled surfaces to be applicable to model nonadiabatic dynamics. The potential matrix elements are evaluated within either the local harmonic or bra-ket-average (linear) approximations to the potential energy surfaces, the latter being a more practical option. Performance of the QTAG method is demonstrated and discussed for the Holstein and Tully models, which are the standard benchmarks for method development in the area of nonadiabatic dynamics.

Ulick syndrome, also called apparent mineralocorticoid excess is an autosomal recessive disorder that causes severe hypertension with polyurea, polydipsia , and other symptoms. We report a case report of two dichorionic diamniotic twins from a first-degree consanguineous couple who suffered from variable symptoms of Ulick syndrome.

Density functional theory (DFT) was used to calculate the most stable structures of Gen (n=2-5) clusters as well as the adsorption energies of Gen (n=2-5) clusters after adsorbing single water molecule. The calculation of the reaction paths between Gen (n=2-5) and single water molecule shows that water molecule can react with Gen (n=2-5) clusters to dissociate to produce hydrogen, and O atoms mix with the clusters to generate GenO (n=2-5). According to the energy change of the reactions, the Ge2 cluster is the most efficient among Gen (n=2-5) clusters reacting with single water molecule. The NPA and DOS respectively proved that the Ge atoms in the product don’t reach the highest valence, and it was jointly predicted that GenO (n=2-5) might continue to react with more water molecules. Our findings contribute to better knowledge of Ge’s chemical reactivity, which could aid in the development of effective Ge-based catalysts and hydrogen-production methods.

Community-level traits as a way to partly circumvent the culturing problem in mycorrhizal trait-based ecology?Chagnon, P.-L.Data availability statement: No new data has been generated in this manuscript.Traits are the intermediate by which species respond to environmental filters and influence ecosystem functions. With the myriad of biogeochemical processes controlled by fungi, the past decade has witnessed a rising interest in applying trait-based approaches, core to the toolkit of plant and animal ecophysiologists, to fungi. One of the first challenges to tackle when working on fungal ecophysiology is to circumscribe the very definition of what we consider a fungal trait. Traits are characteristics/features possessed by an individualthat can influence how it interacts with its environment. Here the individual scale is both important, and problematic. Important because the very goal of comparative ecology is to measure traits on individuals belonging to known species. This allows to populate trait databases, and syntheses of such databases can reveal key trade-offs and trait syndromes that govern species’ life-histories. The scale of the individual is problematic, however, because it is hard to define for soil fungi, and because a rare minority of fungi can be sampled at the individual scale in the environment (e.g., macroscopic sporocarps, ectomycorrhizal root tips, lichen thalli). Beyond this minority, the individual organisms can only be accessed/sampled through establishing fungal cultures, which probably represents one of the main bottlenecks in the development of fungal trait databases. In this issue, Zhang et al. (2022) show how interesting insights in fungal trait-based ecology can be gained by working at the community level.In their study, Zhang et al. (2022) adapted a protocol developed by Neumann & George (2005) to capture mycorrhizal fungal hyphae using ingrowth bags. If we assume that most hyphae recovered through this technique are mycorrhizal, the washed hyphae can be characterized through various chemical/morphological downstream analyses. Measuring such traits for biomass recovered from whole communities is akin to estimating community-weighted mean (CWM) traits, which are central to many aspects of ecophysiology. Various paradigms/theories in community ecology assume some form of equilibrium between species and their environment (Leibold et al., 2004). If we assume (1) a heterogeneous environment, (2) species as reproductively isolated units competing for space/resources and (3) traits as determinants of their reproductive success, correlations between species traits and environmental parameters are naturally expected to arise (Shipley et al., 2011). Under specific stable environmental conditions, a species bearing certain traits should have a higher probability to (1) occur and (2) become abundant in such environment. At the community level, we thus expect a correlation between CWM traits (the sum of species mean traits weighted by their relative abundances), and environmental parameters (box 1). With mycorrhizal fungi, we can have a reasonable access to species’ relative abundances through sequence-based profiles of communities, but the species × traits matrix remains inaccessible. The shortcut taken by Zhang et al. (2022) is to take measurements of traits (here, hyphal C:N:P stoichiometry) at the community level directly.Does the species × traits become dispensable in mycorrhizal ecology? Certainly not. Bringing mycorrhizal fungi into cultures, identifying traits likely to represent important trade-offs in fungal resource management strategies (Chagnon et al., 2013), ensuring reproducible measurement of such traits and establishing common resources to share such traits (Kattge et al., 2020; Zanne et al., 2020) remains a priority of mycorrhizal ecophysiology. Opinions (Chagnon et al., 2013) and definitions (Chaudhary et al., 2020) will only be useful if followed by actual work to populate databases currently storing the very fragmentary data on fungal traits. We cannot leave aside this important work at the species and individual scales, because evolutionary trade-offs defining resource management and life history strategies emerge at those very scales, not at the community level (Grime & Pierce, 2012).Trait-environment relationships, however, can inform us on the way environmental pressures may select for particular species characteristics, and in this regard, progress can be made over much shorter timescales than the work expected to rely on permanent culture banks and individual-level trait measurements. Zhang et al. (2022), for example, identified an increase in hyphal P concentrations in response to warming and drought treatments, illustrating hyphal stoichiometry as a potentially important “response trait” for mycorrhizal fungi. The upcoming challenge with stoichiometry is now to link form and function. What is the purpose of enhanced mycelial P for the fungus? Luxury uptake and storage as polyphosphates, which may confer bargaining power to the fungus? Increased cellular concentration of “growth-related molecules” (sensu Zhang et al., 2022) such as RNA? This remains to be elucidated. The same is true for nitrogen, which can be present in both growth- and function-related proteins, or in cell wall components slowing down necromass decomposition (Fernandez et al., 2019). This will influence how likely are fungal hyphae to contribute to soil organic pools of different turnover times (See et al., 2022; Klink et al., 2022).We can probably identify many other traits that we expect to be (1) measurable at the community level and (2) associated with environmental filters. Spore size and wall ornamentations could be linked to dispersal dynamics (e.g., Chaudhary et al., 2020). Cell wall thickness could be linked with susceptibility to fungivory (as a constitutive structural defense), and could be expected to be associated with predation risk, but also community-level productivity. Generally, structural defenses are expected to be maximal under harsh conditions promoting conservative species with long-lived, constitutively defended tissues (Coley, 1988). Hyphal allocation allometry to the root vs. the soil habitats already has received considerable attention (e.g., Maherali & Klironomos, 2007), although the assumption that extensive soil foraging is associated with more efficient P return to host can be questioned (Jakobsen et al., 1992). Community-level allometric measurements could be coupled with soil nutrient availability along natural or experimental gradients could clarify this issue. Relative mycelial investments in the soil, however, is a multifaceted trait that bears implication for other aspects of fungal growth and dispersal, namely the colonization of new patches (emerging roots), the exposition to parasites/predators, and the interactions with non-mycorrhizal microorganisms potentially including hyphosphere mutualists. In other words, soil hyphae are not strictly foraging units, but may also serve dispersal, chemical warfare and interkingdom cooperation. This may decrease the probability of finding clear univariate linkages between hyphal allometry and single environmental filters such as nutrient availability. Other traits requiring our attention are biomass growth and turnover rates. Tissue maximal growth rate and lifespan are central to the definition of ecological strategies (e.g., Westoby et al., 2002; Darling et al., 2012). In principle, this can be measured at the community level for mycorrhizal fungi, although the experimental approach should be selected wisely. Traditional approaches to measuring biomass accumulation in mycorrhizal studies typically rely either on microcosms inoculated with fungal propagules, or on ingrowth bags. Both these approaches will select for colonists that can rapidly invade this new empty niche (a bulk sterile pot/ingrowth bag), thus biasing our estimates of growth rates in favor of those displayed by ruderal colonists (i.e., community-level trait not matching the community composition/structure). However, regarding biomass turnover rates, it could be envisaged to derive such estimate using stable isotope probing targeting a specific biomarker (e.g., NLFA 16:1ω5). The only drawback is that evaluating dilution rate of heavy carbon in such a biomarker rapidly makes the cost per sample prohibitive, hampering measurements of biomass turnover rates along environmental gradients, or in response to an experimental treatment.Despite the technical difficulties associated with measuring community-level traits, or the challenges to linking form and function, the approach put forth by Zhang et al. (2022) with hyphal stoichiometry are part of the equation to advance mycorrhizal ecophysiology, and should be extended to other traits. Meanwhile, the long-term objective for mycorrhizal ecophysiologists should still be to isolate and culture strains, and make these permanent resources for them and other research groups to measure traits in future studies. Intraspecific trait variation appears so important, at least for arbuscular mycorrhizal fungi (e.g., Munkvold et al., 2004; Antunes et al., 2011), that strain identity will be just as important as species identity in building trait databases. And as mycorrhizal ecophysiology matures, new traits will gain interest and have to be measured on those strains for which we have already measured a number of other traits. Plant and animal ecophysiologists have a permanent resource they can sample individuals from: it is called nature. Mycorrhizal ecologists are in need for such analogous resource: permanent culture banks. Thus, it seems that challenges lying ahead in mycorrhizal ecophysiology are multifaceted, encompassing the need for conceptual development, standard laboratory methods, but also creativity in getting long-term funding to maintain biological material.

Automated 3D-image based tracking systems are new and promising devices to investigate the foraging behaviour of flying animals with great accuracy and precision. 3D analyses can provide accurate assessments of flight performance in regard to speed, curvature, and hovering. However, there have been few applications of this technology in ecology, particularly for insects. We used this technology to analyse the behavioural interactions between the Western honey bee Apis melifera and its invasive predator the Asian hornet, Vespa velutina nigrithorax. We investigated whether predation success could be affected by flight speed, flight curvature, and hovering of the Asian hornet and honey bees in front of one beehive. We recorded a total of 603,259 flight trajectories and 5,175 predator-prey flight interactions leading to 126 successful predation events, representing 2.4% predation success. Flight speeds of hornets in front of hive entrances were much lower than that of their bee prey; in contrast to hovering capacity, while curvature range overlapped between the two species. There were large differences in speed, curvature and hovering between the exit and entrance flights of honey bees. Interestingly, we found hornet density affected flight performance of both honey bees and hornets. Higher hornet density led to a decrease in the speed of honey bees leaving the hive, and an increase in the speed of honey bees entering the hive, together with more curved flight trajectories. These effects suggest some predator avoidance behaviour by the bees. Higher honey bee flight curvature resulted in lower hornet predation success. Results showed an increase of predation success when hornet number increased up to 8 individuals, above which predation success decreased, likely due to competition among predators. Although based on a single colony, this study reveals interesting outcomes derived from the use of automated 3D tracking to derive accurate measures of individual behaviour and behavioural interactions among flying species.

Precision in measurement of glucose level in artificial pancreas is a challenging task and mandatory requirement for the proper functioning of artificial pancreas. A suitable machine learning technique for the measurement of glucose level in artificial pancreas may play crucial role in the management of diabetes. Therefore in the present work, a comparison has been made among few machine learning (ML) techniques for measurement of glucose levels in artificial pancreas because the machine learning is an astounding technology of artificial intelligence, and widely applicable in various fields such as medical science, robotics, environmental science, etc. The models namely decision tree (DT), random forest (RF), support vector machine (SVM), and K-nearest neighbours (KNN), based on supervised learning, are proposed for the dataset of Pima Indian to predict and classify the diabetes mellitus. Ensuring the predictions and accuracy up to the level of DMT2, the comparative behavior of all four models has been discussed. The machine learning models developed here stratifies and predicts whether an individual is diabetic or not based on the features available in the data set. Dataset passes through pre-processing and machine learning algorithms are fitted to train the dataset, and then the performance of the test results has been discussed. Error matrix (EM) has been generated to measure the accuracy score of the models. The accuracies in prediction and classification of DMT2 models are 71%, 77%, 78%, and 80% for DT, SVM, RF and KNN algorithms respectively. The KNN model has shown a more precise result in comparison to other models. The proposed methods have shown astounding behaviour in terms of accuracy in the prediction of diabetes mellitus as compared to previously developed methods.

It is a debate whether trunk twisting belongs to environmental alteration or genetic variation. Through a diallel cross experiment, we first determined that trunk twisting of Yunnan pines was controlled by recessive genes. Anatomical analysis identified that straight and twisty types differed in xylem and phloem. RNA-seq of materials enriched by laser microdissection revealed three genes involved in auxin signal transduction, photosynthesis, and sucrose metabolism, namely ARF, POR, and CBH. These genes were co-expressed at different growth stages of twisty types, and among them, ARF is crucial regulating trunk twisting formation. The enzyme activities involved in sucrose metabolism, carbon fixation, and glycolysis were significantly increased after exogenous auxin was added to twisty types. When auxin signal transduction inhibitor (auxinole) and transport inhibitor (TIBA) were added, the plant height and related pathways were more obviously reduced in straight types. ARF can not only downregulate POR to block chlorophyll synthesis but also allows abundant sucrose to synthesize cellulose. Nevertheless, due to downregulated CBH expression and abnormal cellulolysis, cellulose accumulates and the lignin content decreases, eventually making the trunk highly prone to twisted growth. This study suggests that ARF can be vital in trunk shape screening during the early growth of Yunnan pines.

Ewing sarcoma is children’s second most common malignant bone tumor after osteosarcoma. Relapsed and/or treatment-refractory cases have a poor prognosis. Cabozantinib is a tyrosine kinase inhibitor (TKI) that targets vascular endothelial growth factor (VEGF) and MET. Here, we present data on two children with metastatic Ewing sarcoma who received cabozantinib therapy. In both cases, the disease regressed significantly, symptoms improved, and side effects were manageable. Further research is needed to determine whether cabozantinib can maintain sustained disease control in children with Ewing sarcoma.

Background Rebound thymic hyperplasia (RTH) is a common phenomenon caused by stress factors such as chemo- (CTX) or radiotherapy with an incidence of up to 40%. Misinterpretation of RTH and thymic lymphoma relapse (LR) may lead to unnecessary diagnostic procedures including invasive biopsies or treatment intensification. The aim of this study was to identify parameters that differentiate between RTH and thymic LR in the anterior mediastinum. Methods After completion of CTX, we analyzed CTs and MRIs of 291 patients with classical Hodgkin lymphoma (CHL) and adequate imaging available from the European Network for Pediatric Hodgkin lymphoma C1-trial. In all patients with biopsy proven LR an additional FDG-PET-CT was assessed. Structure and morphologic configuration in addition to calcifications and presence of multiple masses in the thymic region and signs of extrathymic LR were evaluated. Results After CTX, a significant volume increase of a new or growing mass in the thymic space occurred in 133 of 291 patients. Without biopsy only 100 patients could be identified as RTH or LR. No single finding related to thymic regrowth allowed differentiation between RTH and LR. However, the vast majority of cases with thymic LR presented with additional increasing tumor masses (34/35). All RTH patients (65/65) presented with isolated thymic growth. Conclusion Isolated thymic LR is very uncommon. CHL relapse should be suspected when increasing tumor masses are present in distant sites outside of the thymic area. Conversely, if regrowth of lymphoma in other sites can be excluded, an isolated thymic mass after CTX likely represents RTH.

A high-sensitivity double-roughness-structure (DRS) and its innovative manufacturing processes are originally proposed for the improvement on the sensing of the non-reactive molecule. The nitrogen molecules are served as the non-reactive test target in the study. In the DRS, the high roughness graphene is embedded into/onto the roughness surface of the porous silicon, and such the porous silicon is specially made by the “bottom-hole assisted approach” to get high-quality films. It is proved that the DRS reveals the double reinforcement on the improvement of the sensitivity based on the high surface-to-volume ratio in the sensing on non-reactive molecules.

We analyze multifractality for green bonds, stock sector indices, and US economic sector bonds. Green bonds and US bonds show non-linear cross-correlations. We perform Mul-tifractal Detrended Cross-Correlations Analysis (MF-DCCA) to analyze multifractal cross-correlations and the weak version of the Efficient Market Hypothesis (EMH). Our findings are relevant to academics, financial professionals and the general public. Although green bonds are bonds used exclusively to finance sustainable investments, they are still inefficient assets. We find that bond indices for consumer staples and equity indices for information technology and the real state sector can be used to hedge investments in green bonds.

The complete mitochondrial genomes of two Prophantis Warren, 1896 species in the tribe Trichaeini (Lepidoptera: Crambidae) were sequenced using high-throughput sequencing technology. They were assembled and annotated: the complete mitogenomes of P. octoguttalis and P. adusta were 15,197 bp and 15,714 bp, respectively, and contain 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and an A + T-rich region. Their arrangement was consistent with the first sequenced mitogenome of Lepidoptera, from Bombyx mori (Bombycidae). The nucleotide composition was obviously AT-biased, and all protein-coding genes, except for the cox1 gene (CGA), used ATN as the start codon. Except for trnS1, which lacked the DHU arm, all tRNA genes could fold into the clover-leaf structure. Phylogenetic trees of Pyraloidea were reconstructed based on mitogenomic data using Maximum likelihood (ML) and Bayesian inference (BI) analysis methods. The results showed that Trichaeini formed a monophyletic group with high branch support in Spilomelinae, sister to Nomophilini. In addition, the phylogenetic relationships among subfamilies of Pyraloidea were generally stable: (Galleriinae + ((Epipaschiinae + Pyralinae) + Phycitinae)) + ((Pyraustinae + Spilomelinae) + ((Odontiinae + Glaphyrinae) + CAMMSS clade)), although the affinities of some subfamilies in the “CAMMSS clade” were still unresolved.

Background and aims: Opioids are commonly prescribed to patients with chronic low back pain (LBP) despite risks of harms. We conducted a discrete choice experiment (DCE) to determine factors contributing to a general practitioner’s (GP’s) decision to prescribe either an opioid or an NSAID to a patient with chronic LBP. Methods: GPs recruited through an online survey distributed in Australia were presented with 12 questions that represented hypothetical clinical scenarios of a patient with chronic LBP. The clinical scenario varied by two patient attributes; LBP with or without referred leg pain (sciatica) and comorbidities. Participants chose their preferred alternative either an opioid, NSAID or neither (“opt-out”). Each alternative varied by three clinical attributes: the type of opioid or NSAID, the degree of pain reduction and number of adverse events. Results: 210 GPs participated in the survey. Overall, GPs preferred to prescribe an NSAID (45.2%, 95% CI 38.7% to 51.7%) over an opioid (28.8%, 95% CI 23.0% to 34.7%). However, there was no difference between the type of NSAID or opioid preferred. Patient attributes of comorbidities (zero, one, two or three), and the presence of referred leg pain (sciatica) did not influence prescribing preferences, nor did clinical attributes of pain reduction and adverse events. Conclusions: GPs prefer to prescribe an NSAID over an opioid for a patient with chronic LBP. This preference appeared fixed and was not changed by clinical (drug type, degree of pain reduction or number of adverse events) or patient attributes (comorbidities or presence of referred leg pain).

The COVID-19 pandemic has had a significant influence on the medical system and pharmaceutical sector in practically every nation on the planet. Communication with patients in their homes away from clinics was a typical practice in order to give safety actions to the healthcare team; however, health services have been interrupted on many levels throughout the world. The financial success of hospitals and health insurers was impacted by these measures. Another difficulty in this circumstance was the inability of medication manufacturers to get active medicinal components from Chinese companies. The considerable disruption of international trade and travel has had a negative effect on the actual economy. Different procedures based on currently available drugs were used to treat coronavirus infections.

Reactivation of the scar resulting from intracutaneous injection of Bacillus Calmette-Guérin (BCG) is a common specific reaction in Kawasaki’s Disease. It has also sporadically been associated with viral infections, Multisystem Inflammatory Syndrome in Children, influenza vaccination and mRNA COVID-19 vaccination. Since the start of the COVID-19 vaccination campaign in January 2021, the Netherlands Pharmacovigilance Centre Lareb has received 22 case reports of BCG reactivation after vaccination with a COVID-19 vaccine. In 20 case reports it concerned mRNA COVID-19 vaccines Moderna (14) and Pfizer (6). In 2 case reports the viral vector COVID-19 vaccine AstraZeneca was administered. Erythema and pain were the most frequently reported symptoms and the size of the inflammation was between 1.5 to 5 cm. BCG reactivation occurred with a median time to onset of 2 days after the second or booster COVID-19 vaccination, whereas the median time to onset was 7 days after the first COVID-19 vaccination. None of the BCG reactivations were treated. The exact mechanism of the occurrence of this specific reaction remains unknown, however involvement of heat shock protein 65 is suggested. BCG reactivation is a non-serious, self-limiting reaction that can occur after vaccination with both mRNA and viral vector COVID-19 vaccines.

It is well known that the response to and metabolism of the drugs entering human body varies widely across individuals, one of which the reason is that such interpersonal differences may be related to gut microbes. On one hand, drugs or xenobiotics entering into human body may affect the composition of the gut microbiome; on the other hand, the gut microbiota may alter the ADME process of drugs or xenobiotics vise versa. But the majority of studies were focused on the interaction of general population cohorts with the gut microbiota, which is not compatible with the real clinic. For example, irritable bowel syndrome, a common functional disorder of the gastrointestinal tract, of which the gut microbiota is closely associated with the progression and treatment of the disease. Under the disease status, the composition of the gut microbiota is altered and affects the pharmacokinetics, efficacy and toxicity of xenobiotics. With a regard to irritable bowel syndrome, few researches reported that xenobiotics administration process was gut microbial-mediated, while effected on drug efficacy and toxicity as well. Thus, the correlation between gut microbiota and xenobiotics administration, especially the drugs administered, needs to be elucidated. This review links interpersonal differences between gut microbiome and drug metabolism, which plays a significant role in the implications for medical therapy and drug development in irritable bowel syndrome indications. Key words: gut microbiota, gut microbiota-drug interaction, xenobiotics, pharmacokinetics, probiotics

Animals exhibit unique spatial and temporal behaviors that enhance their survival. Understanding such behaviors is an important step towards effective conservation and management especially of threatened species. In this study, we experimented on whether the Pancake tortoise had the ability to home if translocated and also investigated on site fidelity and territoriality of the species in the natural habitats in Kitui County, Kenya. Behavior of 39 tortoises inhabiting 12 spatially separated rock crevices was studied from July 2020 to June 2022 through radio-tracking, camera trapping and combination of group-level scan sampling and ad libitum sampling. Fourteen of the tortoises were fitted with radio-transmitters and trans-located from their respective home crevices to other crevices away from their respective home crevices and their movement and behavior monitored. With an exception of only two females that adapted well to the new crevices of translocation, all the other tortoises attempted homing, with 46.15% of them tracing their way back to their home crevices with accurate precision and 15.38% also reaching areas believed to be within their home range. The successful homing indisputably gives evidence of strong site fidelity in the species. An analysis of the tortoise crevice occupancy showed that there was no statistically significant difference between numbers of the tortoises initially present in the crevices with the average number present over 162 sampling days (F(1,22) = 0.0699, P >0.05), further supporting strong site fidelity in the species. On the other hand camera trapping events and ad libitum sampling also proved the Pancake tortoises to be territorial with males aggressively defending their territories from other incoming males. Key Words: Animal behavior, chelonian conservation, Ecology, radio-tracking, homing ability.
