Determination of Antioxidant, Anti-Alzheimer, Antidiabetic, Antiglaucoma and Antimicrobial Effects of Zivzik Pomegranate (Punica granatum)-A Chemical Profiling by LC-MS/MS.

Zivzik pomegranate (Punica granatum) has recently sparked considerable interest due to its nutritional and antioxidant properties. To evaluate the antioxidant capacities of P. granatum juice, ethanol (EEZP), and water (WEZP) extracts from peel and seed, the antioxidant methods of 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid radical (ABTS•+) scavenging, 1,1-diphenyl-2-picrylhydrazyl free radical (DPPH•) scavenging, Fe3+-2,4,6-tris(2-pyridyl)-S-triazine (TPTZ) reducing, Fe3+ reducing, and Cu2+ reducing methods were used. The antioxidant capacities of samples were compared with the most commonly used synthetic antioxidants, i.e., BHA, BHT, α-tocopherol, and Trolox. In terms of setting an example, the IC50 values of EEZP for ABTS•+ and DPPH• scavenging activities were found to be lower than standards, at 5.9 and 16.1 µg/mL, respectively. The phenolic and flavonoid contents in EEZP peel were 59.7 mg GAE/g and 88.0 mg QE/g, respectively. Inhibition of α-glycosidase, α-amylase, acetylcholinesterase, and human carbonic anhydrase II (hCA II) enzymes was also investigated. EEZP demonstrated IC50 values of 7.3 µg/mL against α-glycosidase, 317.7 µg/mL against α-amylase, 19.7 µg/mL against acetylcholinesterase (AChE), and 106.3 µg/mL against CA II enzymes. A total of 53 phenolic compounds were scanned, and 30 compounds were determined using LC-MS/MS. E. coli and S. aureus bacteria were resistant to all four antibiotics used as standards in hospitals.

Evaluation and comparison of tick detachment techniques and technical mistakes made during tick removal.

BACKGROUND: Tick is among the important ectoparasites of humans and animals. Ticks may transmit disease-causing pathogens to humans. Tick contact may be resulted in several viral and bacterial infections, including Crimean-Congo Hemorrhagic Fever. Timely removal of ticks with appropriate methods is important in prevention of disease transmission. There are many methods reported for tick detachment. In this study, we aimed to evaluate two of them, suture lassoing and freezing and to compare both methods and to examine technical mistakes with these techniques. METHODS: This study was designed as a prospective cross-sectional study, and included the ticks detached by healthcare professionals or directly by patients who presented to the emergency department due to tick contact. The ticks were recorded as larvae, nymphs, and adults according to their growth period. Ticks detachment types with surgical sutures and removal mistakes were recorded. RESULTS: The majority (77.4%) of the ticks were removed by healthcare professionals and a lower rate by patients themselves with hand (22.6%). No technical mistake was found in 72 (77.4%) patients, and the tick was detached as a whole, while detached broken in 15 (16.1%) patients, and the tick was detached as a whole, but the sutures were attached wrong in six (6.5%) patients. Tick broken off due to technical mistakes was most commonly seen in the ticks removed by the individuals themselves. CONCLUSION: The results of this study suggest that when appropriately and correctly used, both suture lassoing and tweezers are effective in tick removal. Public awareness-raising and training programs should be increased on this issue.

Urogenital Myiasis Caused by Psychoda albipennis.

Myiasis is one of the reasons for urogenital parasitosis in our country. Psychoda albipennis is a fly that leads to urogenital myiasis. In this case, a 28-year-old female with complaints of dysuria, nausea, vomiting, abdominal pain, and dropping larvae with urine was referred to our hospital. Larvae in the urine sample were macroscopically and microscopically examined. Subsequently, the patient was diagnosed with urogenital myiasis due to P. albipennis fourth phase larvae. The symptoms were relieved with antibiotic and urinal antiseptic treatments. A diagnosis of urogenital myiasis should be considered in patients with urogenital complaints.

Local treatment of chronic osteomyelitis with surgical debridement and tigecycline-impregnated calcium hydroxyapatite: an experimental study.

OBJECTIVE: The aim of this study was to determine the efficacy of tigecycline-impregnated hydroxyapatite in the local treatment of chronic osteomyelitis experimentally induced in rat tibias with methicillin-resistant Staphylococcus aureus. STUDY DESIGN: Monocortical defects were established in the left tibias of 32 adult Wistar albino rats. Five rats were randomly selected and injected intramedullarly with saline solution (group 1), whereas chronic osteomyelitis was induced in other rats by intramedullary injection of S. aureus. Infected rats were then randomized and divided into 4 groups: group 2, no further treatment; group 3, debridement only; group 4, debridement followed by implantation of calcium hydroxyapatite; and group 5, debridement followed by implantation of tigecycline-impregnated calcium hydroxyapatite. On day 21 after induction, all rats in groups 2-5 showed signs of osteomyelitis. Rats in groups 1 and 2 were killed on day 21 after induction, whereas rats in groups 3, 4, and 5 underwent debridement surgery on day 21 after induction and were killed 21 days after debridement surgery. Tibias were analyzed histopathologically and cultured for S. aureus. RESULTS: Compared with group 2, histopathologic disease severity scores in groups 3, 4, and 5 were 37%, 44%, and 83% lower, respectively. Nontreated infected rats had the highest bacteria count (mean 5 × 10(5) colony-forming units/g bone), and bacterial count was 26%, 29%, and 79% lower in groups 3, 4, and 5, respectively, compared with group 2. CONCLUSIONS: Tigecycline-impregnated hydroxyapatite can have a potential in the treatment of chronic osteomyelitis of methicillin-resistant S. aureus origin, which may be considered as a therapeutic alternative by surgeons dealing with osteomyelitis.

Serratia ficaria isolated from sputum specimen.

Serratia ficaria was first described in 1979 as a Gram-negative facultative anaerobic rod. S. ficaria was found in figs, but also isolated from human specimens in a few cases. We now report an isolate of S. ficaria from sputum specimen.A 46-year-old man was suffering from a chronic renal failure of five years, four months of peritoneal dialysis and one week of fever due to respiratory tract infection, accompanied by cough. Sputum culture yielded a Gram-negative rod. It was identified as S. ficaria and the antibiotic susceptibility test was performed by automated Vitek II (bioMerieux). The tested S. ficaria strain was susceptible to amikacin, gentamicin, cefepime, trimethoprim-sulfamethoxazole, imipenem, meropenem, tigecycline and ciprofloxacin. This strain was resistant to ampicillin, amoxicillin-clavulanic acid, cephalothin, cefoxitine, cefuroxime and ceftriaxone. The patient was treated successfully (80 mg trimethoprim/400 mg sulfamethoxazole twice daily for 7 days)S. ficaria is an opportunistic pathogen responsible for intestinal colonization or serious infections such as septicaemia, gall bladder empyema in immunocompromised patients. The fig tree and fig play an important role in human colonization. It should be remembered that S. ficaria infections may be encountered frequently especially in fig tree culture zones.

[Tularemia seroprevalence in the risky population living in both rural and urban areas of Erzurum]. / Erzurum Merkez ve Kirsalinda Yasayan Riskli Gruplarda Tularemi Seroprevalansi

Tularemia which is a zoonotic infection, caused by Francisella tularensis, has become a re-emerging disease in Turkey. Infection is often transmitted to human by handling animal tissues and products, but it is also possible to acquire the disease from contaminated water or food. Recently several cases and epidemics of tularemia have been reported in the northwest areas of Turkey, particularly in Marmara and West Black Sea regions. Erzurum is a city in Eastern Anatolia Region, Turkey and animal husbandry is the main agricultural activity in that area. However, neither tularemia cases were reported from this province nor seroprevalence studies were performed. In this study we aimed to determine F.tularensis antibody seropositivity in the risky population living at both rural and urban area of Erzurum. Blood samples from 240 volunteer subjects (134 male with mean age: 36.2, age range: 17-75 years and 106 female with mean age: 39.1, age range: 16-77 years) whose occupations were farming and animal husbandry, were included in the study. Serum samples were screened for the presence of F.tularensis antibodies by slide agglutination method (BD, USA) and Serazym ELISA kit (anti-F.tularensis IgG/IgA/IgM, Seramun, Germany). The positive samples with those tests were also retested by microagglutination test (MAT) in National Tularemia Reference Laboratory of Refik Saydam Hygiene Center, using antigen prepared in the same laboratory from the local strain. The serum samples were also searched for the presence of Brucella and Salmonella antibodies in terms of cross-reactivity. Seropositivity was detected in 71 (29.6%) out of 240 subjects by slide agglutination test (SAT), whereas only 5 (2.1%) gave positive result for total antibody by ELISA. Twenty-five of the 71 SAT positive samples yielded F.tularensis antibodies by MAT, of which 21 were between 1/20-1/40 and four were between 1/80-1/160 titers. However, all of the MAT positive samples (n= 25) were found reactive in Brucella and/or Salmonella antibody tests. One of the four MAT positive samples with 1/40 titer and all of the four MAT positive samples with ≥ 1/80 titer yielded positive results in ELISA. Since MAT gave very high cross reactive results, the five subjects (2.1%) found positive with ELISA were evaluated as seropositive for tularemia. Of those subjects (four were female, one was male; age range: 27-38 years), four were the inhabitants of the same village, and one from another neighboring village. All of the seropositive subjects were dealing with raising livestock and two were also farming. No history of contact with rat and wild animals or tick bite were detected, however it was noted that non-chlorinated fountain water has been used in both of these villages. In conclusion, our data emphasized that, populations inhabiting especially in rural area and dealing with farming and stock raising in our region are at risk for tularemia.

Medical faculty and school of health student knowledge of and behavior regarding swine flu and vaccine, in Kahramanmaras, Turkey.

This study was carried out to determine Medical Faculty and School of Health student knowledge of and behavior regarding swine flu and vaccine. The study was carried out at Kahramanmaras Sutcuimam University School of Health among the medical faculty and students. All 296 students of the Kahramanmaras Sutcuimam University School of Health and 76 students of the Faculty of Medicine were supposed to participate in the study. Ninety-six point one percent of the students in the study know high fever was one of the symptoms of swine flu, 91.8% said it was spread directly by sneezing or coughing and 95.5% knew washing hands with soap and water especially after coughing and sneezing, should be done to reduce the.risk of infection. Sixty-five point four percent of students knew fatigue and body aches were adverse effects of the swine flu vaccine. Only 9.6% of students received the pandemic flu vaccine. Their knowledge regarding symptoms and methods of spread was low, but regarding measures taken for prevention was high. Both swine flu knowledge and vaccine knowledge were higher in those who received the flu vaccine than in those who did not receive it. In pandemic situations, training should be given immediately to medical, midwifery and nursing students who are models for society.

The use of 808-nm light therapy to treat experimental chronic osteomyelitis induced in rats by methicillin-resistant Staphylococcus aureus.

BACKGROUND DATA: In vivo and in vitro studies have reported that laser energy in differing wavelengths and irradiation regimes has a potential bactericidal effect on Staphylococcus aureus. OBJECTIVE: The purpose of this study was to investigate whether a light wavelength of 808 nm in varying doses has an effect on chronic osteomyelitis induced experimentally in the rat tibia. METHODS: Intramedullary cavities were surgically created in the left tibias of 39 adult Wistar albino rats. Five randomly selected subjects were injected with a sterile saline solution, and methicillin-resistant S. aureus (MRSA) was used to induce osteomyelitis in the remaining rats. After 3 weeks, rats with evidence of osteomyelitis were treated with debridement alone (n = 7), with debridement plus laser irradiation to induce photoeradication (n = 21), or were not treated at all [negative control, (n = 6)]. Active irradiation was performed using an 808 nm, 100 mW continuous-wave diode laser with a beam spot size of 0.7854 cm(2) (irradiance = 127.3 mW/cm(2)). Laser treatment commenced immediately after debridement surgery and was applied daily for 5 consecutive days. Irradiation lasted 60 secs (6 J at 7.64 J/cm(2): n = 7), 120 secs (12 J at 15.29 J/cm(2): n = 7), or 180 secs (18 J at 22.93 J/cm(2): n = 7). Rats in the sham and negative control groups were killed 21 days post-induction surgery, and those in the treatment groups were killed after 42 days. Following killing, tibias were removed and analyzed histopathologically, radiographically, and microbiologically. RESULTS: Histopathological analysis showed that infection levels had decreased by 37%, 67%, 81%, and 93% in the groups treated by debridement or by debridement plus 7.64, 15.29, and 22.93 J/cm(2) light therapy, respectively, compared to the negative control group. Osteomyelitis-induced rats had the highest bacteria count (5 × 10(5)). Bacterial counts fell to 1.6 × 10(4), 4.3 × 10(2), 5.5 × 10(1), and 3.3 × 10(0) in groups treated by debridement or by debridement plus 7.64, 15.29, and 22.93 J/cm(2) light therapy, respectively, compared to the negative control group. CONCLUSIONS: Within the limitations of this study, laser phototherapy with the appropriate irradiation parameters appears to be a promising adjunct and/or alternative technique to pharmacological agents in the treatment of osteomyelitis. The 808 nm 100 mW (127.3 mW/cm(2)) laser device used in this study achieved a maximum effect with an irradiation time of 180 secs, delivering 18 J at an energy density of 22.93 J/cm(2).

Status of pandemic influenza vaccination and factors affecting it in pregnant women in Kahramanmaras, an eastern Mediterranean city of Turkey.

BACKGROUND: Pregnant women are a target group for receipt of influenza vaccine because there appears to be an elevated mortality and morbidity rate associated with influenza virus infection in pregnant women. The goal of this study is to determine the factors affecting the decisions of pregnant women in Turkey to be vaccinated or not for 2009 H1N1 influenza. METHODOLOGY: We enrolled 314 of 522 (60.2%) pregnant women who attended to the antenatal clinics of the Medical Faculty of Kahramanmaras Sutcuimam University's Department of Gynecology and Obstetrics between December 23, 2009, and February 1, 2010. We developed a 48-question survey which was completed in a face-to-face interview at the clinic with each pregnant woman. PRINCIPAL FINDINGS: Of the 314 pregnant women, 27.4% were in the first trimester, 33.8% were in the second trimester, and 38.8% were in the third trimester. Twenty-eight pregnant women (8.9%) got vaccinated. Of all the women interviewed, 68.5% stated that they were comfortable with their decisions about the vaccine, 7.3% stated they were not comfortable, and 24.2% stated that they were hesitant about their decisions. The probability of receiving the 2009 H1N1 vaccine was 3.46 times higher among working women than housewives, 1.85 times higher among women who have a child than those who do not, and 1.29 times higher among women with a high-school education or higher than those with only a secondary-school education and below. Correct knowledge about the minimal risks associated with receipt of influenza vaccine were associated with a significant increase in the probability of receiving the 2009 H1N1 vaccine. CONCLUSIONS/SIGNIFICANCE: The number of pregnant women in the study group who received the 2009 H1N1 vaccine was very low (8.9%) and two-thirds of them stated that they were comfortable with their decisions concerning the vaccine. Our results may have implications for public health measures to increase the currently low vaccination rate among pregnant women. Further studies are required to confirm whether our findings generalize to other influenza seasons and other settings.
