Superficial CD34-positive fibroblastic tumor is an infrequent soft-tissue tumor characterized by a lesion located in the subcutaneous fascia without affecting the soft or deep muscle planes. Its incidence is unknown; therefore, it represents a diagnostic challenge for both the surgical oncologist and pathologist. Given its high risk of local recurrence, extensive surgical resection is the recommended treatment modality. This is the first report of this rare entity in Latin-America.

Blumea lacera (Burn. f.) DC. (Family: Asteraceae) is an important member of Bangladeshi natural plant resource and it is an herbaceous weed locally known as Kukursunga. Different parts of this plant are used traditionally to cure various diseases. But detail study on the antioxidant and antineoplastic potentials of Blumea lacera leaves, has not yet been done. Aim of this study is to examine the antioxidant and antineoplastic properties and quantify the different type of phytochemical content of the methanolic extract of leaves of Blumea lacera (MELB). MELB contained a rich polyphenol, flavonol, flavonoid and proanthocyanidins. MELB showed moderate cytotoxic effect against Artemia salina (brine shrimp nauplii) where its LD50 values was 66.12 μg/ml. In vitro antioxidant assay, MELB exhibited a remarkable capacity to scavenge the tested reactive species. MELB scavenged DPPH with an IC50 of 33.64 μg/mL and 42.69 μg/mL, respectively. In vivo antineoplastic assay, MELB significantly (P<0.05) decreased viable cell count and increased the survival time of EAC cell bearing mice. Hematological profiles were also restored significantly (P<0.05) to normal levels in MELB treated mice as compared to untreated EAC control mice. In addition, fluorescence microscopic view of EAC cells derived from MELB-treated group showed apoptotic characteristics in treated cells compared to untreated EAC control. our findings suggest that methanolic extract of Blumea lacera leaves(MELB) might be a potential agent with antioxidant properties for prevention of cancer and has the merit for further investigation in isolating its active constituents.

Purpose: We aimed to create mechanic optic nerve injury model in rats and investigate the neuroprotective effects of ripasudil on retinal ganglion cells. Study Design: Experimental study Methods: Mechanic optic nerve injury model was created in the right eyes of male Wistar rats (n=15). Rats were divided into three groups: glaucoma model with sham treatment (group1) and 20 µM intravitreal ripasudil treatment (group 2) and 50 µM intravitreal ripasudil treatment (group 3). Treatment was applied intravitreally and rats were sacrificed at the end of 4 weeks. Glial fibrillary acidic protein (GFAP), Brn-3a antibody,anti- Iba1 was examined by immunohistochemistry. Results: The number of Brn-3a positive RGC in the mechanical optic nerve injury model was 5.33 ± 2.08 (min: 3, max: 7) in sham group, 10.25 ± 2.63 (min: 8, max: 14) in 20 µM group and 16.75 ± 5.43 (min:9, max: 21) in 50 µM group (p <0.05). GFAP positive RGC counts were recorded as 24.33 ± 2.08 (min: 22, max: 26) in sham group, 16.75 ± 1.70 (min: 15, max: 19) in 20 µM group and 13.00 ± 4.08 (min:10 , max: 19) in 50 µM group (p <0.05). Ripasudil treatment also decreased Iba1 expression in the retina of mechanic optic nerve injury groups. In addition, ripasudil treatment prevented apoptotic cell death by increasing Bcl-xL protein expression and preserved Tfam protein expression in the retina. Conclusions: Our experimental study has shown that ripasudil is neuropreotective in mechanical optic nerve injury model.

Several viruses are often believed to be associated with acquired aplastic anemia. There is paucity of literature proving the association between viruses and aplastic anemia. We aimed to study the association of aplastic anemia with Human Parvovirus B19 (B19V), Epstein Barr virus (EBV), Cytomegalovirus (CMV), Hepatitis viruses, Measles virus (MV), Varicella Zoster virus (VZV) and Adenovirus (AdV). Between January 2020 to December 2020, confirmed cases of aplastic anemia and age and sex matched controls of iron deficiency anemia were enrolled in the study. They were tested for the above- mentioned viruses for antigen and/or IgM antibody by ELISA and/or nucleic acid by Real Time PCR in serum samples. Relevant history was collected. Cases were followed up at 3, 6 and 12 months after enrollment for recording the outcome. Total 68 cases and 34 controls were included in the study of which 61(89.70%) cases and 12(38.23%) controls were positive for markers of at-least one of the 10 viruses studied. B19V, EBV, CMV and Hepatitis B virus were found to be significantly associated with aplastic anemia. Five patients died within 12 months. Mortality was not associated with viral infections. Viral infections may play a role in pathogenesis of acquired aplastic anemia.

Marine organisms, scientists, governmental and non-governmental organizations face a significant challenge as a result of the ubiquitousness of plastic and microplastics in the aquatic environment, particularly in Nigeria where there is little or no policy put in place to address the issue of microplastic pollution. Nigeria ranks ninth globally in terms of its contribution to ocean plastic pollution and currently does not have a federal ban on the majority of single-use plastics and equipment. This paper aimed to present the status of plastic pollution in Nigeria and some policies to curb the menace. Data analysis reveals that Bayesa, Katsina, Lagos, and Oyo are the four states that generate the majority of the plastic waste in Nigeria. The number of industries, markets, and urbanization in a location affect the quantity of plastic waste that is produced there and is not dependent on the population. This paper makes some policy suggestions and recommendations such as the federal prohibition and taxation on the use of plastic, ocean clean-up, technological innovation that will support the recycling industry in Nigeria, and the need for additional plastic research. Nigeria can apply the most recent plastic waste management strategies in European and Asian nations as a model and adopt them to reduce marine plastic pollution.

Cystic fibrosis (CF) is an inherited disorder caused by genetic mutations encoding the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) is a CFTR modulator shown to improve lung function in certain patients with CF. We undertook this study to determine its effects on glycemic outcomes in pediatric patients with cystic fibrosis-related diabetes (CFRD). We reviewed the medical records and identified two subjects, referred to as subject A and subject B, with CFRD on insulin therapy at Duke University Hospital between 2019-2020 who were on treatment with ELX/TEZ/IVA for at least one year. The mean hgbA1C pre- and post- treatment was 5.65% (5.6-5.7) and 5.05% (5.0-5.1) respectively with a mean reduction of 0.6% (p value 0.01). Improvement in hgbA1C occurred in the absence of increased insulin requirements, subject B remained on a similar insulin regimen whereas subject A was able to come off insulin completely. In addition, improvements in BMI z-score were seen in both groups with a mean BMI z-score of -0.30 pre-treatment (-0.71-0.11) and z-score of +0.28 post-treatment (0.11-0.45).

Nickel production for electric vehicle batteries increases by 30% every year. As the country with the most nickel production in 2021, Indonesia will operate six nickel refining plants with High-pressured acid leaching technology and one development of Step Temperature Acid Leach technology. Problems arise with many hydrometallurgical-based nickel refining plants where the leach residue will continue to accumulate and potentially pollute the soil environment. Lateritic nickel leach residue has a high Fe content reaching 44.45% in the form of hematite and an S content of around 1.3%. Besides, demand growth in the iron and steel industry is greater than the availability of its raw materials. Thus, secondary sources for raw materials for the iron and steel industry are needed. The maximum S content for steel raw materials is 0.1%, so the sulfur content in leach residue must be removed. This research focuses on removing sulfur content in lateritic nickel leach residue by roasting at a temperature of 500 °C until 1100 °C. The experiment was continued with reduction roasting at various temperature profiles. The reduced phase of the roasted leach residue sample is then compared with the reduced phase of the initial leach residue sample. Sulfur content decreases with increasing roasting temperature. Sulfur content reaches ~0% at a roasting temperature of 1100 °C. The optimum initial sample reductive roasting temperature of lateritic nickel leach residue was 1400 °C with 95.9% Fe content and 0.1% S in metal. The optimum reductive roasting temperature for 1100 °C roasted samples was 1200 °C with 94.6% Fe content and 0% S. Roasting treatment can reduce the optimum temperature for the reduction roasting process.

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
