Background/aim: Ankaferd hemostat (ABS; Ankaferd blood stopper, Istanbul, Turkey) is a folkloric medicinal plant extract. The aim of this study was to determine the effect of Ankaferd hemostat (ABS) on the fate of Helicobacter pylori strains. The study also aims to determine alterations in the antimicrobial resistance of three different H. pylori strains in response to ABS exposure.Materials and methods: H. pylori Strain 1 was obtained from the culture collection ATCC 43504 and passaged three ti...

This study was undertaken to compare the fattening performance, carcass traits and the organoleptic qualities of the meat of kids and lambs conventionally reared at the Dairy research farm of Cukurova University. Ten Boer kids and ten Assaf lambs were involved in the study. Experimental animals were collectively housed and fed based on hay and concentrate feed for forty days. In order to assess the characteristics of the carcass, four animals from each group were slaughtered. In addition, meat s...

A liquid chromatography tandem mass spectrometry (LC-MS/MS) method with modified QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction cleaning process was comprehensively validated for determination of 167 pesticide residues in three matrices: milk, cheese and cream. Optimisation of the mass spectrometry parameters was performed by injecting pesticide standard solutions into the electrospray ion (ESI) source. The mass spectrometer was operated in the positive ESI mode. The valida...

Ankaferd hemostat (Ankaferd Blood Stopper®, ABS)-induced pharmacological modulation of essential erythroid proteins can cause vital erythroid aggregation via acting on fibrinogen gamma. Topical endoscopic ABS application is effective in the controlling of gastrointestinal (GI) system hemorrhages and/or infected GI wounds. Escherichia coli O157:H7, the predominant serotype of enterohemorrhagic E. coli, is a cause of both outbreaks and sporadic cases of hemorrhagic colitis. The aim of this study i...

Goats play a predominant role in the economies of millions of people, and they have been a source of meat, milk, skin, wool, and fiber since ages. Goats undergo various kinds of stressors under many different conditions, i.e., physical, nutritional, chemical, and physiological and heat stress (HS). Among all, thermal stress is the most concerning nowadays in the ever-changing climatic scenario, which supposes a serious long-term challenge faced by small ruminant owners worldwide. HS results in d...

Currently, even countries located within the temperate zone are affected by changes in global warming. These changes are associated with unprecedented events of extremely high ambient temperature, above 40 °C, and seasonal changes. The number of days with temperature humidity index above a specific comfort threshold (>68) has noticeably increased in recent years in the Mediterranean region. The rate of global warming, including in the temperate zone, is expected to continue to vulnerable in comi...

Introduction. Ankaferd hemostat (ABS) is the first topical haemostatic agent involving the red blood cell-fibrinogen interactions. The antihemorrhagic efficacy of ABS has been tested in controlled clinical trials. The drug induces the formation of an encapsulated complex protein web with vital erythroid aggregation. The aim of this study is to detect the essential toxicity profile and the antioxidant molecules inside ABS. Methods. The pesticides were analyzed by GC-MS and LC-MS. The determinatio...

abstract The aim of the present study was to investigate the effect of lactic acid against Shiga toxin producingEscherichia coli (O157:H7 and non-O157 serogroups including O103, O111, O145 and O26) at differentconditions. Soybean sprouts and spinach leaves inoculated with each serogroup of E. coli(~7.00 þ 1.00 log 10 cfu/g) were treated with the lactic acid solutions at different concentrations (0%(control),1.5%, 2.0%, or 2.5%) and at different temperatures (20, 40, or 50 C) for 3 min. Results i...

Emerging foodborne pathogens are challenging subjects of food microbiology with their antibiotic resistance and their impact on public health. Campylobacter jejuni, Salmonella spp. and Verotoxigenic Escherichia coli (VTEC) are significant emerging food pathogens, globally. The decrease in supply and increase in demand lead developed countries to produce animal products with a higher efficiency. The massive production has caused the increase of the significant foodborne diseases. The strict contr...
