Evaluating the Optimum Transplanting Time for Different Coarse Rice Genotypes under Semi-Arid Conditions of Faisalabad

引用

Agricultural Sciences 2018年第1期9卷 69-77页

作者： Muhammad Ahtisham Tahir Muhammad Ahmad Arain Saba Durrani Abdul Shakoor Ahtsham Bilal Nasir Ali Muhammad Ishfaq Umer Farooq siraj ahmed Muhammad Irfan Department of Agronomy University of Agriculture Faisalabad Pakistan Department of Botany University of Agriculture Faisalabad Pakistan Department of Plant Breeding and Genetics University of Agriculture Faisalabad Pakistan Department of Plant Breeding and Genetics Bahauddin Zakariya University Multan Pakistan

Continuously changing climate and availability of different rice genotypes make it necessary to find optimum time of sowing as well as suitable variety for cultivation to get maximum productivity under a specific set of climatic conditions. A field study was carried out to search out the suitable rice transplanting time for four different coarse genotypes under the semi-arid environment of Faisalabad. The experiment was conducted at Agronomic Research Area, University of Agriculture, Faisalabad and was laid out in randomized complete block design (RCBD) with split plot arrangement keeping transplanting time in main plots while rice genotypes in subplots. Variability among treatments was measured by Fisher’s ANOVA (P ≤ 5%) and LSD test was applied to compare the differences among treatments’ means. The ANOVA indicated statistically significant differences among genotypes as well as transplanting dates irrespective of all studied traits while interactive effects of both were found to be non-significant. NIBGE-1 performed best with maximum paddy yield of 6.05 t/ha while KSK-434 performed poor with paddy yield of 2.78 t/ha. Increased paddy yield and yield related parameters of all rice genotypes were recorded where transplantation was done on 25th of June. Generally, paddy yield decreased with delaying the transplanting time. The results suggested that NIBGE-1 can perform better under the semi-arid conditions of Faisalabad and last week of June might be the optimum time for nursery transplantation. It can also be further elucidated that late transplanting causes yield reduction which could not be recommended among farmers.

Curcumin:reclaiming the lost ground against cancer resistance

引用

Cancer Drug Resistance 2021年第2期4卷 298-320页

作者： siraj Shaikh Javed Shaikh Yusufi Sadia Naba Kailas Doke Khursheed ahmed Mujahid Yusufi Post-Graduate Department of Chemistry and Research Center Abeda Inamdar Senior College of ArtsScience and Commerce(Affiliated to SPPU)Pune 411001India Advanced Scientific Research Laboratory Azam CampusPune 411001India.

Curcumin, a polyphenol, has a wide range of biological properties such as anticancer, antibacterial, antitubercular, cardioprotective and neuroprotective. Moreover, the anti-proliferative activities of Curcumin have been widely studied against several types of cancers due to its ability to target multiple pathways in cancer. Although Curcumin exhibited potent anticancer activity, its clinical use is limited due to its poor water solubility and faster metabolism. Hence, there is an immense interest among researchers to develop potent, water-soluble, and metabolically stable Curcumin analogs for cancer treatment. While drug resistance remains a major problem in cancer therapy that renders current chemotherapy ineffective, curcumin has shown promise to overcome the resistance and re-sensitize cancer to chemotherapeutic drugs in many studies. In the present review, we are summarizing the role of curcumin in controlling the proliferation of drug-resistant cancers and development of curcumin-based therapeutic applications from cell culture studies up to clinical trials.

In the textile industry, cotton is the most popular choice among all the natural fibers due to its unique properties such as softness, affinity to skin, biodegradability, absorbency, and moisture being comfortable to wear. Zinc Oxide Nanoparticles (ZnO NPs) were produced and coated on cotton fabrics. The concentration of Zinc acetate was varied. 2-methoxy-ethanol has been used as a solvent. Using the dip coating technique, ZnO NPs have been coated on the cotton fabric in different mole concentrations. Scanning Electron Microscopy (SEM), Ultraviolet Visible (UV-VIS) spectroscopy, the antifungal and antibacterial activity of the ZnO NPs was performed on the coated fabrics. The SEM images depicted that the nanoparticles are well dispersed on the fabric at 3M concentration of ZnO solution. It was found that the UV absorbance increases with the increase of concentration up to 2M concentration and after that it decreases. It was also found that maximum antibacterial and antifungal activity is at 2M concentration.

Knowledge, Attitude and Practice (KAP) Assessment of Intestinal Parasitic Infection among School Children in Asmara, Eritrea

引用

Health 2017年第1期9卷 57-68页

作者： Khawaja Shakeel ahmed Nuredin Mohamedkassm siraj Henok Fitsumberhan Sara Isaac Semhar Yohannes Dawit Eman Yacob Berhane Matiwos Araya Department of Biomedical Sciences Asmara College of Health Sciences Asmara Eritrea

Purpose: Poor hygiene practice, inadequate sanitary conditions and lack of awareness of correct mode of transmission are some factors that attribute to high intestinal parasitic infection among children. Therefore, having proper knowledge, good attitude and practice (KAP) against the aforementioned factors can significantly mitigate the spreading of intestinal infection. Methods: The present study was a cross-sectional study which comprised of 127 students who were selected by stratified random sampling. A self-administered questionnaire was used to record KAP of students against intestinal parasitic infection. Total 126 students gave stool samples which were analysed by formol-ether concentration technique. In addition, sewage samples were also collected and analysed for any parasitic load. Statistical data were generated by Chi-square test. Results: A total of 126 stool samples were examined in the study of which 46 (36.50%) were found infected with one or more intestinal parasites. Among the parasites identified, the most common was Hymenolepsis nana with a prevalence rate of 35 (76.0%). Here, most of the students 96 (76.1%) were having poor knowledge about the correct mode of transmission of intestinal parasites. Majority of the students 91 (72.2%) practicing defecation in open air when they are at home, and all 126 (100%) are doing that at school, and significant number of students were not washing hands after defecation. Conclusion: Lack of knowledge regarding mode of transmission and practice of defecation in open air and not washing hands after defecation are issues of great concern, because many parasitic infection have faecal-oral mode of transmission. So, health authorities have to take these issues seriously and action would be vital to resolve it.

Transitional cell carcinoma （TCC） of the ovary is a rare and recently recognized subtype of ovarian epithelial cancer. We presented the first case report from our Institute （Sheri Kashmir Instiute of Medical Sciences, Srinagar, India）, which was initially rnisdiagnosed as stromal cell carcinoma （granulosa cell tumour）, and on review of histopathology with immunohistochemistry, the diagnosis of TCC of the ovary was established. The aim of this article was to describe the typical case of primary TCC of the ovary and to review the literature for information on TCC management.
