We present a case of Nannizziopsis spp infection in an immunocompromised patient, describe clinical findings, investigation results and treatment. This rare fungal infection is reported in reptiles and humans, but not other mammals. There are only twenty case reports in medical literature to date, most in immunocompromised patients.
A 64-year-old kidney transplant recipient from urban Nigeria presented with a verrucous plaque on his dorsal left hand which has grown rapidly over the two months. He was concerned that it might represent cancer. On further examination he also had a subcutaneous fluctuant masses on his left flank and left upper arm, a fleshy mucosal plaque and a large tender fluctuant swelling over his right tibia. He was clinically well, but in the preceding months he reported haemoptysis and 7 kilograms weight loss.
Skin biopsies from multiple sites showed identical features: suppurative granulomatous inflammation and elongated elements consistent with fungal hyphae. Grocott special staining showed scattered fungal hyphae. Beta-D-glucan was raised at 441.4 pg/mL [3-6 pg/mL]. Subsequent molecular identification confirmed Nanniziopsis spp, likely to be N. guarroi. He was treated with intravenous amphotericin-B for 7 weeks and was then switched to oral posaconazole for one month with complete resolution.
Nannizziopsis is an emerging human pathogenic fungus that predominantly causes disease in immunocompromised individuals. This case highlights the importance of suspecting atypical fungal infection in immunocompromised individuals presenting with polymorphic skin lesions and the critical diagnostic role of skin biopsy and culture.

The hydrolysis of xylo-oligosaccharides catalyzed by β-xylosidase plays an important role in the degradation of lignocellulose. However, the enzyme is easily inhibited by its catalytic product xylose, which severely limits its application. Based on molecular docking, this paper studied the xylose affinity of Aspergillus niger β-xylosidase An-xyl, which was significantly differentially expressed in the fermentation medium of tea stalks, through cloning, expression and characterization. The synergistic degradation effect of this enzyme and cellulase on lignocellulose in tea stems was investigated. Molecular docking showed that the affinity of An-xyl to xylose was lower than that of Aspergillus oryzae β-xylosidase with poor xylose tolerance. The Ki value of xylose inhibition constant of recombinant-expressed An-xyl was 433.2 mmol/L, higher than that of most β-xylosidases of the GH3 family. The Km and Vmax towards pNPX were 3.6 mmol/L and 10 000 μmol/(min·mL), respectively. The optimum temperature of An-xyl was 65 ℃, the optimum pH was 4.0, 61% of the An-xyl activity could be retained upon treatment at 65 ℃ for 300 min, and 80% of the An-xyl activity could be retained upon treatment at pH 2.0-8.0 for 24 h. The hydrolysis of tea stem by An-xyl and cellulase produced 19.3% and 38.6% higher reducing sugar content at 2 h and 4 h, respectively, than that of using cellulase alone. This study showed that the An-xyl mined from differential expression exhibited high xylose tolerance and higher catalytic activity and stability, and could hydrolyze tea stem lignocellulose synergistically, which enriched the resource of β-xylosidase with high xylose tolerance, thus may facilitate the advanced experimental research and its application.

OBJECTIVE:
To explore the underlying mechanism of inhibition by Jinkui Shenqi Pills (JKSQP) on glucocorticoid-enhanced axial length elongation in experimental lens-induced myopia (LIM) guinea pigs.
METHODS:
Sixty 2-week old male guinea pigs were randomly divided into 4 groups with 15 guinea pigs in each group, according to the random numbers generated by SPSS software: control, LIM, saline and JKSQP groups. The control group includes animals with no treatment, while the guinea pigs in the other 3 groups received lens-induced myopization on the right eyes throughout the experiment (for 8 weeks). The saline and JKSQP groups were given daily intraperitoneal injections of 10 mg/kg hydrocortisone for 2 consecutive weeks at the same time, and then orally administered either saline or JKSQP [13.5 g/(kg•d) for 6 consecutive weeks. Body weight, anal temperature and animal appearance were observed and recorded to evaluate the GC-associated symptoms. The ocular parameters, including refraction and axial length, were measured by streak retinoscopy and A-scan ultrasonography, respectively. The levels of plasma hormones associated with the hypothalamic-pituitary-adrenal axis (HPAA), including free triiodothyronine, free thyroxine, estradiol and testosterone, were measured by radioimmunoassay, and cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate were measured by enzyme-linked immunosorbent assay. In addition, the mRNA and protein expressions of retinal amphiregulin (AREG) was measured by quantitative real-time polymerase chain reaction and Western blotting, respectively.
RESULTS:
JKSQP effectively increased body weight and anal temperature, improved animal appearance and suppressed axial length elongation in glucocorticoid-enhanced myopic guinea pigs with normalization of 4 HPAA-associated plasma hormones (all P<0.05). The plasma level of cAMP was significantly increased, whereas the plasma level of cGMP and the mRNA and protein expressions of retinal AREG were decreased after treatment with JKSQP (all P<0.05).
CONCLUSION
JKSQP exhibited a significant inhibitory effect on axial length elongation with decreased expression of AREG in the retina, and normalized 4 HPAA-associated plasma hormones and the expression of cAMP and cGMP in GC-enhanced myopic guinea pigs.

This research assessed the experience of stakeholders and the efficacy of integrating traditional medicine into the Ghanaian health system using the Ashanti Region as the focal point. Elements of an integrative healthcare delivery model including philosophies/values, structure, process and outcome were used to conduct a quality assessment of the integrated health system in Ghana. Each element clearly showed that Ghana is currently not running a coordinated health practice model, thus making it a tolerant, rather than an inclusive, health system. Therefore, the primary purpose of this research is to discuss the development of a new and appropriately customised model that could enhance the practice of integrated healthcare in Ghana. The model we present has flexibility and far-reaching applicability in other African countries because such countries share similar socio-cultural and economic characteristics. As such, governments and health practitioners could adapt this model to improve the practice of integrated healthcare in their specific settings. Hospital administrators and health system researchers could also adapt the model to investigate or to monitor the progress and efficacy of integrated healthcare practices within their settings. This might help to understand the relationships between the integration of traditional medicine and health outcomes for a given population.

Philippine Journal of Nursing 2023;93(1):84-90
INTRODUCTION:
Nurses' expertise and recommendations from nurses are essential sources of opinions and recommendations for
policy development. Nurses must be actively involved in politics, and nursing could play an essential role in shaping health policy.
However, the influence of political efficacy, political astuteness, and health policy advocacy exposes a gap in the current
knowledge.
DESIGN AND METHODS:
The study utilized descriptive correlational design and mediating analysis. Purposive sampling was used
to select six hospitals in Ghana, and simple random sampling was used to select five hundred and seventy-nine nurses. The study
used the Political Efficacy Scale, Social Justice Advocacy Scale, and the Political Astuteness Inventory. The data were analyzed
by mean and Standard deviation, Pearson coefficient, ANOVA, and GLS mediation.
RESULTS:
Nurses in Ghana had a low political efficacy and health policy advocacy. Moreover, political astuteness had moderate
astuteness. A Pearson Correlation coefficient showed a moderately significant positive relationship between political efficacy and
health policy advocacy. Furthermore, political astuteness and health policy advocacy showed a statistically significant low
positive relationship. There was no significant difference in political efficacy and health policy advocacy when age, academic
qualification, nurses' rank, and years of professional experience were considered. Political astuteness partially mediated the
relationship between political efficacy and health policy advocacy.
CONCLUSION
Nurses in Ghana have limited belief in their ability to understand and affect politics and have limited participation in
healthcare advocacy initiatives. Furthermore, nurse respondents have the adequate ability of a nurse to understand political
knowledge, political participation, and legislative understanding to advocate health policies.

Objective: To investigate the histological features and clinical manifestations in different types of cardiac amyloidosis to improve diagnostic accuracy. Methods: The histopathological features and clinical manifestations of 48 patients diagnosed with cardiac amyloidosis by Congo red stain and electron microscopy through endomyocardial biopsy were collected in West China Hospital of Sichuan University from January 2018 to December 2021. Immunohistochemical stains for immunoglobulin light chains (κ and λ) and transthyretin protein were carried out, and a review of literature was made. Results: The patients age ranged from 42 to 79 years (mean 56 years) and the male to female ratio was 1.1 to 1.0. The positive rate of endomyocardial biopsy was 97.9% (47/48), which was significantly higher than that of the abdominal wall fat (7/17). Congo red staining and electron microscopy were positive in 97.9% (47/48) and 93.5% (43/46), respectively. Immunohistochemical stains showed 32 cases (68.1%) were light chain type (AL-CA), including 31 cases of AL-λ type and 1 case of AL-κ type; 9 cases (19.1%) were transthyretin protein type (ATTR-CA); and 6 cases (12.8%) were not classified. There was no significant difference in the deposition pattern of amyloid between different types (P>0.05). Clinical data showed that ATTR-CA patients had less involvement of 2 or more organs and lower N-terminal pro-B-type natriuretic peptide (NT-proBNP) than the other type patients (P<0.05). The left ventricular stroke volume and right ventricular ejection fraction of ATTR-CA patients were better than the other patients (P<0.05). Follow-up data of 45 patients was obtained, and the overall mean survival time was 15.6±2.0 months. Univariate survival analysis showed that ATTR-CA patients had a better prognosis, while cardiac amyloidosis patients with higher cardiac function grade, NT-proBNP >6 000 ng/L, and troponin T >70 ng/L had a worse prognosis (P<0.05). Multivariate survival analysis showed that NT-proBNP and cardiac function grade were independent prognostic factors for cardiac amyloidosis patients. Conclusions: AL-λ is the most common type of cardiac amyloidosis in this group. Congo red staining combined with electron microscopy can significantly improve the diagnosis of cardiac amyloidosis. The clinical manifestations and prognosis of each type are different and can be classified based on immunostaining profile. However, there are still a few cases that cannot be typed; hence mass spectrometry is recommended if feasible.

Biomedical and Environmental Sciences 2023;36(1):86-93
OBJECTIVE:
To analyze the global epidemic status of the Ebola virus disease (EVD) and assess the importation risk into China.
METHODS:
Data from World Health Organization reports were used. We described the global epidemic status of EVD from 1976-2021, and assessed and ranked the importation risk of EVD from the disease-outbreaking countries into China using the risk matrix and Borda count methods, respectively.
RESULTS:
From 1976-2021, EVD mainly occurred in western and central Africa, with the highest cumulative number of cases (14,124 cases) in Sierra Leone, and the highest cumulative fatality rate (85%) in the Congo. Outbreaks of EVD have occurred in the Democratic Republic of the Congo and Guinea since 2018. The importation risk into China varies across countries with outbreaks of disease. The Democratic Republic of the Congo had an extremely high risk (23 Borda points), followed by Guinea and Liberia. Countries with a moderate importation risk were Nigeria, Uganda, Congo, Sierra Leone, Mali, and Gabon, while countries with a low importation risk included Sudan, Senegal, and C

Scopoletin is a coumarin compound with various biological activities including detumescence and analgesic, insecticidal, antibacterial and acaricidal effects. However, interference with scopolin and other components often leads to difficulties in purification of scopoletin with low extraction rates from plant resource. In this paper, heterologous expression of the gene encoding β-glucosidase An-bgl3 derived from Aspergillus niger were carried out. The expression product was purified and characterized with further structure-activity relationship between it and β-glucosidase analyzed. Subsequently, its ability for transforming scopolin from plant extract was studied. The results showed that the specific activity of the purified β-glucosidase An-bgl3 was 15.22 IU/mg, the apparent molecular weight was about 120 kDa. The optimum reaction temperature and pH were 55 ℃ and 4.0, respectively. Moreover, 10 mmol/L metal ions Fe2+ and Mn2+ increased the enzyme activity by 1.74-fold and 1.20-fold, respectively. A 10 mmol/L solution containing Tween-20, Tween-80 and Triton X-100 all inhibited the enzyme activity by 30%. The enzyme showed affinity towards scopolin and tolerated 10% methanol and 10% ethanol solution, respectively. The enzyme specifically hydrolyzed scopolin into scopoletin from the extract of Erycibe obtusifolia Benth with a 47.8% increase of scopoletin. This demonstrated that the β-glucosidase An-bgl3 from A. niger shows specificity on scopolin with good activities, thus providing an alternative method for increasing the extraction efficiency of scopoletin from plant material.

Aims:
The main aim of the study was to evaluate some methods of application of Aspergillus niger AD1 and Trichoderma hamatum T-113 for enhancing the growth and yield of wheat var. Ibaa99 in pots and field conditions.
Methodology and results:
Plant growth-promoting fungi (PGPF) loaded with peat moss were used at a rate of 100, 150 and 200 mL pot-1 or m-2 in filed soil; seed treatment (coating) with fungi suspension 19 × 107, soil treatment and combination of all the three methods was employed in the study. Wheat seeds were sown in pots and field plots during 2018-2019, and data regarding various growth and yield attributes were recorded. In both pot and field trials, the results revealed that the best treatments for the desired plant growth and yield attributes were peat moss 150 mL alone or in combination with soil and seed treatments. The soil physicochemical parameters were also improved after inoculation with selected fungal isolates in different application methods compared with un-inoculated control treatment in both pot and field conditions.
Conclusion, significance and impact of study
The PGPF play a vital role represented phytoremediation, phytostimulation and bio-fertilization. The isolates of PGPF, which were applied with peat moss at 150 mL to the pot and in the field alone or combined with seed treatment and soil application, were significantly the best effective method for improving wheat attributes.
