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.

Background: Limited data on large cohort of patients with malignant tumors of the scalp are available in the literature. The aim of this study was to review a large cohort of patients with malignant scalp tumors to determine epidemilogy, tumor characteristics of this region and treatment. Materials and Method: A retrospective review of patients with malignant scalp tumors diagnosed histopathologically between 2005 and 2021 was performed. Demographic features and tumor characteristics were analyzed. Results: A total of 1080 patients (M: F 3,5:1) were treated and followed up for a mean period of 42 months (12-120 months). Age at diagnosis ranged from 12 to 98 years. Most malignant scalp tumors (95,1%) occurred in those 50 years or older and in bald patients (87%). Basal cell carcinomas (59,2%), squamous cell carcinomas (32,2%) and melanomas were the most common histologic types. Incidence was highest on the frontal of temporal region (66,1%). Recurrence was frequently in squamous and basal cell carcinomas but uncommon in melanoma. Conclusions: Tumors of the scalp accounted about 8,01 % of all skin cancers. Tend to be basal and squamous cell carcinomas, many of which occur in the temporal and frontal region of bald men. The outlook for patients with scalp tumor is positive, although we suggest excision margins of at least 3-4 mm and continued clinical vigilance is warranted given their higher recurrence rates.

The use and the production of sanitizers have increased in the post-pandemic situation to prevent the further spread of COVID-19. Usability assessment of sanitizer containers is essentially required to evaluate the effectiveness, efficiency, and satisfactory use of the sanitizer containers. This study aimed to evaluate the system usability scale (SUS) as a marker of perceived usability of non-human computer interfaces, such as - sanitizer containers. The perceived usability of three types of sanitizer containers was evaluated using SUS. The authors have measured the reliability, convergent, and discriminant validity to evaluate SUS as a marker of usability of sanitizer containers. The result showed that SUS lacks convergent validity though it has a higher reliability coefficient. Thus, this is not the best measure of usability for non-human computer interfaces like-sanitizer containers. The SUS was applied on the flip cap, finger-pressure pump, and spray-type sanitizer containers. The finger-pressure pump container has exhibited a higher SUS score than others. The results of this study have given an idea about the usability of three different kinds of sanitizer containers. This research provides an overview of the application of SUS on non-Human computer interfaces like sanitizer containers. This study provides limitations like lack of convergent validity and ideas to overcome common method bias.

This investigation studies the potential use of infrared (IR) sensing technology to answer key questions of scalding. In particular, scalding incidents are frequently plagued by conflicting recollections, uncertain details, and litigation. Questions often relate to how a scalding spill occurred, how hot the liquid was, the direction of liquid flow, and the connection between burn patterns and spill patterns. Flow patterns, among others are sometimes, challenging to determine after a spill incident. Nevertheless, IR technology can be used for event reconstruction and can help identify the typical burn patterns that result from spills. Here, IR imaging is applied to common scald situations. The IR imaging provides temperature information that is continuous in both space and time and can be used with currently available burn models to predict burn depths and patterns. The IR images are used to generate a burn-depth map superimposed on the patient’s body. This study shows that IR imaging leads to reproducible results that can be used to predict burn-depth patterns based on situation specific spills.

26 women with HMB and scarred uterus were included in the study. Data regarding procedure completion, complications, hospital stay, success rate and failure of procedure necessitating hysterectomy was obtained. The majority of the patients had one C/S, 5 had two, one had 3 and two had 4 previous C/S scars. The procedure was completed in 84% of cases. Success rate was 68% (15/22) in the scarred uterus group and 32% (31.8%) (7/22) needed hysterectomy due to continuing heavy periods or pain. One woman in the scarred uterus group had uterine perforation (3.8%) needing overnight admission, all the rest of cases were done as a day procedure. A third (7/22)(32%) of women required a hysterectomy for persistent heavy bleeding or pelvic pain, all were with previous one C/S. The histology of the removed uterus confirmed leiomyomas with or without adenomyosis in all the cases explaining the possible cause of failed Novasure ablation.
