Bacterial resistance to different antimicrobial agents is growing with alarming speed, especially when bacterial cells are living in biofilm. Hybrid nanoparticles, synthesized through the green method, hold promise as a potential solution to this challenge. In this study, 66 actinomycete strains were isolated from three distinct marine sources: marine sediment, the algae , and the marine sponge . From the entirety of the isolated strains, one strain, S26, identified as , was selected based on its taxonomic position and significant antimicrobial activity. Using the biomass of the selected marine , the green synthesis of eco-friendly silver carbonate nanoparticles (BioAgCONPs) is reported for the first time in this pioneering study. The BioAgCONPs were characterized using different spectroscopic and microscopic analyses; the synthesized BioAgCONPs primarily exhibit a triangular shape, with an approximate size of 100 nm. Biological activity evaluation indicated that the BioAgCONPs exhibited good antimicrobial activity against all tested microorganisms and were able to remove 58% of the biofilm formed by the  kp6 strain.

The incidence of squamous cell carcinoma (SCC) is on the rise, making it a significant global health concern. Environmental risk factors are crucial to the development of SCC. This study sought to examine comprehensively the impact of these factors on the onset of SCC. We conducted a cross-sectional study involving 480 participants at Beijing tertiary care hospital. Utilizing structured questionnaires, data on demographics, environmental exposures, medical history and clinical characteristics were collected. The cohort was composed of 272 men (56.67%) and 208 women (43.33%). The majority (44.38%) were between ages of 41 and 60, and Type III skin predominated (34.79%). Most of the participants belonged to the middle socioeconomic class (60.83%). 'Vegetarian' dietary habits (46.67%) were prevalent, as was the 'Sedentary' lifestyle (49.79%). Regarding environmental exposures, moderate sun exposure of 3 to 5 h per day (54.58%) and UV protective eyewear (30.83%) were prevalent. The majority (69.58%) of respondents indicated 'Never' exposure to carcinogens. A variety of wound characteristics were observed, with 'non-smokers' (64.17%) dominating. Most SCC lesions were located on the extremities (40.21%), lasted less than 6 months (44.38%) and measured 1-3 cm (39.79%). The majority (54.58%) did not have a history of cutaneous injuries. Our research uncovered substantial relationships between SCC and numerous environmental variables, gender, Fitzpatrick skin type, occupation, duration of sun exposure, exposure to carcinogens, dietary practices, history of skin wounds, wound location, duration, size and depth were significantly associated with the onset of SCC. These results highlighted the complexity of SCC aetiology and need for individualized prevention and treatment strategies.

Gastric cancer (GC) is a serious public health issue due to its frequency and severity. It is, for both sexes, one of the most common causes of cancer-related death and is a major contributor to the global burden of disease. Recent data show that Epstein-Barr virus (EBV) has been detected in different histopathological subtypes of gastric carcinoma and that EBV-associated gastric carcinoma (EBVaGC) represents about 10% of all cases. Moreover, the LMP1 protein characterizing the malignant transformation of cells in several cancer models seems to be very rarely expressed in this type of cancer. This study aimed to characterize EBVaGC in our population by detecting LMP1 in gastric carcinomas in about 30 selected patients. The results showed that in our population, nuclear staining predominates, showing that the antrum remains the most sampled site both for these pathologies and for LMP1 positivity (nuclear staining). In general, the LMP1 marking was negative for 22.58%, positive with a nuclear predominance at 64.52%, nuclear and cytoplasmic at 12.90%, and no positive marking for the cytoplasm. Results were not like the different studies on the expression of this oncogenic protein without EBVsCG, probably finding an explanation in the fact that our country is among the endemic regions for this herpes virus. In conclusion, the rate of LMP1 expression among gastric carcinomas does not seem similar to that observed in other countries. This study characterizing EBVaGC in Tizi-Ouzou, Algeria, reinforces the need for further studies to clarify the role of EBV (LMP1) and to explore its potential value as a predictive biomarker for the development of this type of cancer pathology.

We are looking into viral components that may contribute to breast cancer in order to find possible therapeutic targets. The Epstein-Barr virus (EBV), which has been found to cause nasopharyngeal carcinoma and Burkitt lymphoma, is thought to play a role in breast cancer. Our series' patients had a median age of 49, with nearly half being under the age of 49. T2 tumors (two to five centimeters in size) make up the vast majority of our collection (60%). Six percent of our patients showed lymph node involvement, with roughly the same number in the N1 and N2 stages (41.17% each). Only 17.64% of people are at the N3 stage. SBR II tumors were the most common (90%). Only 20% of patients have HER2 overexpression, whereas 73.33% have ER expression. EBV was found in 23.33% of breast carcinomas (7 cases/30) after oncoprotein LMP1 expression, but normal surrounding tissues tested negative. We discovered that overexpression of the HER2 protein is inversely related to the two HRs' expression. They have no relationship with EBV infection and, consequently, LMP1 expression. LMP1 expression was not shown to be linked with patient age, tumor grade, tumor size, or lymph node invasion.

Skin Cutaneous Melanoma (SKCM) is a form of cancer that originates in the pigment-producing cells, known as melanocytes, of the skin. Delay wound healing is often correlated with the occurrence of and progression of SKCM. In this comprehensive study, we investigated the intricate roles of two important wound healing genes in SKCM, including Matrix Metalloproteinase-2 (MMP2) and Matrix Metalloproteinase-9 (MMP9). Through a multi-faceted approach, we collected clinical samples, conducted molecular experiments, including RT-qPCR, bisulphite sequencing, cell culture, cell Counting Kit-8, colony formation, and wound healing assays. Beside this, we also used various other databases/tools/approaches for additional analysis including, UALCAN, GEPIA, HPA, MEXPRESS, cBioPortal, KM plotter, DrugBank, and molecular docking. Our results revealed a significant up-regulation of MMP2 and MMP9 in SKCM tissues compared to normal counterparts. Moreover, promoter methylation analysis suggested an epigenetic regulatory mechanism. Validations using TCGA datasets and immunohistochemistry emphasized the clinical relevance of MMP2 and MMP9 dysregulation. Functional assays demonstrated their synergistic impact on proliferation and migration in SKCM cells. Furthermore, we identified potential therapeutic candidates, Estradiol and Calcitriol, through drug prediction and molecular docking analyses. These compounds exhibited binding affinities, suggesting their potential as MMP2/MMP9 inhibitors. Overall, our study elucidates the diagnostic, prognostic, and therapeutic implications of MMP2 and MMP9 in SKCM, shedding light on their complex interplay in SKCM occurrence and progression.

Diabetes mellitus is a chronic metabolic disorder marked by elevated blood sugar levels, leading to organ dysfunction. Curcumin, derived from turmeric, exhibits promise in managing type II diabetes. Nanomicelles were created by conjugating curcumin with chitosan through succinic anhydride. Succinyl-curcumin, the resultant compound, was esterified with chitosan to form a polymer prodrug conjugate. Nanomicelles, formed via dialysis, were spherical with a hydrodynamic size of 49.37 nm. In vitro release studies revealed 97% curcumin release at pH 5 in 7 days. A 21-day experiment on diabetic mice compared nanomicelles, standard drug, and free curcumin's impact on fasting blood glucose. The study showcased gradual, controlled curcumin release from nanomicelles, suggesting their potential in type II diabetes treatment.

Avian pathogenic Escherichia coli and ostriches: a deep dive into pathological and microbiological investigation.

The current project was designed to develop piperine-loaded solid lipid microparticles (SLMs) to assess the anti-arthritic potential of piperine (PIP). Variable proportions of carnauba wax, beeswax, and tween 80 were employed for preparing SLMs by using the solvent evaporation technique. The developed formulations were subjected to particle size measurements, entrapment efficiency (EE), and zeta potential (ZP) determination. Microparticles were also investigated for piperine-lipid compatibility, thermal analysis, surface morphology, piperine (PIP) release trend, and anti-rheumatic activity in rats. The network's grafting was confirmed by FTIR and XRD results. The thermal stability of the constructed network was confirmed by the DSC and TGA results. SEM findings confirm porous surface morphology. The dissolution experiments on SLMs confirmed the sustained release profile, delivering 87.82% to 94.92% of piperine at 7.4 pH for 24 h. All developed formulations followed a zero-order kinetic model and the Korsmeyer-Peppas model. Furthermore, the anti-rheumatic potentials of piperine from SLMs were also investigated and compared with diclofenac sodium (the standard treatment) in a rat model. The analysis revealed that PIP significantly reduced the severity of arthritis, as confirmed by the findings of multiple arthritic assessment parameters.
