Bacterial cellulose (BC) is a versatile biomaterial with unique properties that make it promising for various biomedical applications, including wound healing. The extracellular matrix (ECM) plays a crucial role in wound healing, providing a structural scaffold and signaling cues for cell migration and proliferation. This study investigates the potential of BC as a scaffold for ECM production and its effect on in vivo wound healing. In this work, the bacterial cellulose fermentation process is modified by the addition of Green Propolis and Usnic acid to the culture medium and natural materials before the bacteria are inoculated. In vivo behaviour using natural membranes for regenerative medicine is presented and it is in edit. Overall, our findings demonstrate the potential of BC as a scaffold for ECM production and its beneficial effects on in vivo wound healing. BC-based dressings may offer a novel approach to promoting wound healing and tissue regeneration in clinical settings. Further studies are warranted to optimize BC-based therapies and explore their full potential in regenerative medicine.

Nitrogen and sulfur supplies have a strong influence on the physical characteristics of crop as well as on the quality and quantity of wheat storage proteins, which play an important role in bread-making process. In order to evaluate the contribution of soil and foliar fertilization of nitrogen and sulfur on physiological and quality assessment of wheat, a field trail was carried out having randomized complete block design with four replications and eight different treatments of nitrogen and sulfur combinations were allotted to plots at different growth stages. Results indicated that highest protein content (12.82%), maximum moisture content (10.9%), maximum crop growth rate and maximum absolute growth rate were recorded when the wheat crop was fertilized with T8 [Nitrogen @ 60 kg·ha-1 at sowing + 40 kg·ha-1 at tillering + 10 kg·ha-1 at anthesis (spray) + 10 kg·ha-1 after anthesis (spray)] + [Sulfur @ 15 kg·ha-1 at sowing + 10 kg·ha-1 at anthesis (spray) + 5 kg·ha-1 after anthesis (spray)], while control practice resulted low moisture content, low protein, minimum crop growth rate and low absolute growth rate. Among physiological components of wheat cultivars, leaf area index was enhanced when fertilization was done with T5 (Sulfur @ 15 kg·ha-1 at sowing + 10 kg·ha-1 at anthesis + 5 kg·ha-1 after anthesis). In all the recorded observations,concerning experiment wheat cultivar Pirsabaq2005 showed appreciable response as compared with other variety (Khyber-87). Thus it is possible to obtain maximum physiological traits as well as bread-making quality of wheat through soil and foliar application of nitrogen and sulfur.

Nutritional value of vegetables and high prices of meat and meat originated food compel common people to consume plant originated food particularly salad vegetables. Microbial population of vegetable surfaces contains a large number of pathogenic bacteria including members of Enterobactereace like Escherichia coli (E. coli). A survey was conducted in three major markets of Rawalpindi, Pakistan. Tomato, lettuce, cabbage and cucumber samples were collected from three shops of each market. Each vegetable was analysed as unwashed and washed for total coliforms, faecal coliforms and E. coli by FAO (Food Quality Manual). About two hundred and fifty E. coli isolates were preserved, serotyped for presence of O157 serotype. Total coliforms, faecal coliforms and E. coli count exceeded the permissible limits in most samples. The highest Total coliforms were associated with cabbage (3.78 log10 cfu/g). Cucumber was the least contaminated by Total coliforms (2.15 log10 cfu/g). E. coli was detected in tomato, lettuce, cucumber and cabbage. Washed samples showed reduced bacterial population. Seventy six isolates of E. coli were biochemically characterized and serotyped for O157 antigen. A majority of strains could not be identified by serotyping. These findings conclude with high potentially pathogenic microbial load on salad vegetables and urge for preventive action on priority basis.

This paper presents the impact of mean maximum temperature on Chitral river basin situated at Chitral district and high altitude (>6000 m) peaks of the Hindukush range under changing climate in Pakistan. The analysis of Chitral River as one of the tributary of Kabul River—the second largest river of Pakistan—revealed that change in temperature has a profound influence on the snow/glacial melt in comparison to the mean monthly rainfall. This is because the studied river is faded by the snow and glacial melt and receives a lot of snowfall from winter (DecFeb) to pre-monsoon (April-May). In monsoon period (Jul-Sep), 30% of the time the discharge rate remains above the mean while 60% of the time the discharge is less than the mean in the pre-monsoon (April-May) period. It means that 10% of the time the discharge is in reach of 300% to 900% of the mean flow, showing a rise in water yield and river discharge rate due to increase in mean monthly maximum temperature. Due to this significant increase (p < 0.05), the glaciers start melting faster and disappear in early summer, hence, reducing their residency period to convert into ice. This shows the signals of changing climate transfer into hydrological changes in Pakistan. Our findings are important for agriculture, hydropower and water management sectors for future planning especially in dry season for sustainable food security and for operation of ydrological installations in the country.

Background Wilms tumor (WT) is the most common childhood kidney cancer worldwide, yet its incidence and clinical behavior vary according to race and access to adequate healthcare resources. To guide and streamline therapy in the war-torn and resource-constrained city of Baghdad, Iraq, we conducted a first-ever molecular analysis of 20 WT specimens to characterize the biological features of this lethal disease within this challenged population. Methods Next-generation sequencing of ten target genes associated with WT development and treatment resistance (WT1, CTNNB1, WTX, IGF2, CITED1, SIX2, p53, N-MYC, CRABP2, and TOP2A) was completed. Immunohistochemistry was performed for 6 marker proteins of WT (WT1, CTNNB1, NCAM, CITED1, SIX2, and p53). Patient outcomes were compiled. Results Mutations were detected in previously described WT 'hot spots' (e.g., WT1 and CTNNB1) as well as novel loci that may be unique to the Iraqi population. Immunohistochemistry showed expression domains most typical of blastemal-predominant WT. Remarkably, despite the challenges facing families and care providers, only one child, with combined WT1 and CTNNB1 mutations, was confirmed dead from disease. Median clinical follow-up was 40.5 months (range 6–78 months). Conclusions These data suggest that WT biology within a population of Iraqi children manifests features both similar to and unique from disease variants in other regions of the world. These observations will help to risk stratify WT patients living in this difficult environment to more or less intensive therapies and to focus treatment on cell-specific targets.
