Green synthesis of copper oxide nanocrystals was carried out via hydroxide precipitation using rambutan peel wastes. The successful formation of copper oxide nanocrystals was confirmed by X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Atomic Force Microscopy (AFM) analysis. XRD analysis confirms the calculated average crystallite size of higher intense plane peak (111) was 35.74 nm. SEM and TEM show the surface morphology and look flake-shaped. The AFM analysis shows needle formation of CuO nanoparticles. A possible mechanism for the formation of CuO nanocrystals with rambutan peel extract was also proposed. The prepared nanocrystals were coated on the cotton fabric, and their antibacterial activity was analyzed. Both CuO and CuO nanocrystals coated cotton fabric showed good antibacterial activity towards Escherichia coli E. coli and Staphylococcus aureus S. aureus. Wash durability test was carried out on the test fabrics showed that the significant antimicrobial activity was actively retained in the fabrics treated with CuO...

Poultry products are a major source of animal protein in Ghana. However, disease outbreaks have constantly threatened increased poultry production in some regions of the country. The most common source of human salmonellosis is food of poultry origin. The evolution of resistant strains of Salmonella in natural environments and animal houses presents a serious public health concern. Fluoroquinolones such as ciprofloxacin have remained effective agents in managing salmonellosis and other gastrointestinal infections over the years. However, despite growing evidence on evolving antibiotic resistance in S. typhi, few studies have assessed the susceptibility of salmonella species to commercially marketed ciprofloxacin brands. This study thus sought to determine the susceptibility of S. typhi isolated from 25 poultry farms in the Ashanti region to commercially available ciprofloxacin brands on the Ghanaian market. Antibiotic susceptibility tests were carried out using a modified Kirby Bauer disk diffusion assay and MIC determination by micro-broth dilution. Of the 50 Salmonella typhi isolates, 20% (n=10/50) were susceptible to pure ciprofloxacin, while 58% (29/50) of the isolates were...

Medicinal plants and their investigation towards the phytoconstituents is much interested in today’s research. The plant Achyranthes aspera Linn. is one of the most use full drugs in Siddha and Ayurvedha medicines for treating various diseases in different formulations. Here the aim of this study is to evaluate the pharmacognostic parameters and identify the phytoconstituents. A preliminary phytochemical study helps identify the phytoconstituent present in different extracts, and Column Chromatography was used to isolate the phytoconstituent principle present in the methanol extract. The structure of the isolated compound was elucidated by Spectroscopic methods like UV spectroscopy, IR spectroscopy, NMR spectroscopy, MASS spectroscopy. A yellow crystalline compound was isolated from the methanol extract of Achyranthes aspera Linn. in the fraction of Chloroform: Ethyleacetae in (80:20) ratio. From the spectroscopic method, the structure of the isolated compound was elucidated, and the proposed structure may be (E)-2-(E)-tetracos-21-enoyloxy) ethyl pentacos-22-enoate. The antimicrobial activity of the methanol and aqueous extract of Achyranthes aspera Linn. has also been screened towards bacterial and fungal organisms like...

Perilla frutescens (Linn.) is an annual herbal medicinal, aromatic, vitamins-rich food and ornamental plant that belongs to the mint family, Lamiaceae. It is distributed throughout India, extending to China, Japan, Korea, Taiwan, Vietnam, and other Asian countries. Perilla frutescens seeds, leaves and stems contain fixed oil which is useful edible oil. It is an alternative source of polyunsaturated fatty acids (linolenic acid (54%-64%), i.e., omega-3-fatty acids), phenolic compounds (rosmarinic acids, luteolin, chrysoleriol, quercetin, catechin, protocatechuic acid, and apigenin), natural antioxidants, vitamins and minerals. Recent advances prove that compounds purified from Perilla frutescens have been proven to be biologically active against several major diseases to treat depression-related diseases, anxiety, asthma, chest stuffiness, vomiting, coughs, colds, flu, phlegm, tumors, allergies, intoxication, fever, headache, stuffy nose, constipation, abdominal pain, and indigestion. It also acts as an analgesic, anti-abortive agent, sedative such as an antioxidant, antimicrobial, anti-allergic, antidepressant, anti-inflammatory, anticancer and neuroprotective activities. This present review deals with the update of biological activities of isolated bioactive chemical constituents of Perilla frutescens and explores...

Introduction: Irrational use of drugs is widespread in present-day medical practice. Hence, the present study aimed to analyze the drug prescribing pattern among the patients who visited the Faculty of Dentistry dental clinic, AIMST University. Methods: A retrospective, cross-sectional study was conducted to analyze the drug prescribing pattern of dentists of AIMST University, Kedah, Malaysia. A total of 857 patients’ medical records were scrutinized between January 2018 to March 2018, and only 532 patients’ medical records were identified to have drug prescriptions. Patients’ drug prescription data were collected and analyzed using descriptive statistics. Results: Drug prescription books of 532 patients were analyzed. Female patients were greater in number [325(61.09%)]. The most common dental problem was gingivitis [275(28.29%)] followed by dental carries [215(22.12%)], periodontitis [198(20.37%)] and edentulous [157(16.16%)]. A total of 965 drugs were prescribed, with an average number of 1.81 drugs per prescription. The commonest therapeutic class of drug prescribed was NSAIDs [432(44.77)] followed by antimicrobials [309(32.02)]. The percentage of encounters with an antibiotic prescription was higher (32.02%) than...
