Antimicrobial, Antidiabetic, Antioxidant, and Anticoagulant Activities of In Vitro and In Silico.

In the last decade, the urgent need to explore medicinal plants or drug development has increased enormously around the world to overcome numerous health problems. In the present investigation, HPLC indicated the existence of 18 phenolic and flavonoid compounds in the extract. Hesperetin represents the greatest concentration (25,579.

Molecular Interaction Studies and Phytochemical Characterization of L. Constituents with Multiple Biological Utilities as Antioxidant, Antimicrobial, Anticancer and Anti-Hemolytic Agents.

Multiple biological functions of extract were evaluated in the current work. Phytochemical components of the extract were detected by Gas Chromatography-Mass Spectrometry (GC-MS) and High-performance liquid chromatography (HPLC). Moreover, extract was estimated for antioxidant potential by 2,2-Diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical scavenging, antimicrobial activity by well diffusion, and anticoagulant activity via prothrombin time (PT) and activated partial thromboplastin time (APTT).

Anticancer, antioxidant, antiviral and antimicrobial activities of Kei Apple (Dovyalis caffra) fruit.

Secondary plant metabolites remain one of the key sources of therapeutic agents despite the development of new approaches for the discovery of medicinal drugs. In the current study, chemical analysis, and biological activities of Kei apple (Dovyalis caffra) methanolic extract were evaluated. Chemical analysis was performed using HPLC and GC-MS.

SARS-CoV-2, the other face to SARS-CoV and MERS-CoV: Future predictions.

Coronavirus disease 2019 (COVID-19) outbreak is proving to be an unprecedented disaster that lays its dark shadow on global health, economics and personal freedom. Severe acute respiratory syndrome (SARS) and middle east respiratory syndrome (MERS) epidemics provide scientific data that is useful in better understanding and resolution of COVID-19. Similarities among SARS-CoV, MERS-CoV and SARS-CoV-2 have been investigated in the light of available data.

Antimicrobial activity of some plant extracts against bacterial strains causing food poisoning diseases.

Prevention of food spoilage and food poisoning pathogens is usually achieved by use of chemical preservatives which have negative impacts including: human health hazards of the chemical applications, chemical residues in food & feed chains and acquisition of microbial resistance to the used chemicals. Because of such concerns, the necessity to find a potentially effective, healthy safer and natural alternative preservatives is increased. Within these texts, Plant extracts have been used to control food poisoning diseases and preserve foodstuff.

Prevalence of Helicobacter pylori infection and the incidence of ureA and clarithromycin resistance gene 23S rRNA genotypes status in Saudi Arabia.

Objectives: To determine the prevalence of Helicobacter pylori ureA and clarithromycin resistance gene 23S rRNA genotypes among H. pylori in Saudi Arabia.

Methods: A total of 100 serum and fecal samples from 70 patients and 30 healthy volunteers, from patients who presented with symptoms suggestive of gastritis or peptic ulcer disease, were taken from the main hospital in the Southern region of Saudi Arabia from September 2010 C.

Assessment of the potential risk of infection associated with Clostridium difficile from porcine xenografts.

There are numerous concerns over the potential for transfer of pathogens between species during clinical xenotransplantation, and although current clinical application is limited, porcine xenografts have been previously used to treat patients with severe burns. Donor animals providing the xenografts are sourced from a healthy commercial herd, however, as pigs are a known source of zoonotic agents, a number of diseases are required to be excluded from pigs used for xenotransplantation purposes. Many studies have indicated the relevance of viral zoonoses, however, little has been done with regard to the potential for transfer of pathogens related to health care associated infections.

Clostridium difficile in ready-to-eat salads, Scotland.

Of 40 ready-to-eat salads, 3 (7.5%) were positive for Clostridium difficile by PCR. Two isolates were PCR ribotype 017 (toxin A-, B+), and 1 was PCR ribotype 001.
