A preliminary study of the effect of phytoadditive carvacrol on the trace elements (Cu, Mn and Zn) content in fish tissues

Phytoadditives have gained increasing interest as feed additives for fish. The aim of the present study was to determine whether selected dietary phytoadditive can influence the bioavailability of several trace elements (Cu, Mn and Zn), which play an important role in the physiological processes. The experiments were carried out at a commercial trout farm. A total of 420 juvenile rainbow trout (mean weight ± SD = 10.79±0.57), Oncorhynchus mykiss, were randomly allocated into four different treatments with three replicates each. Fish were kept in raceways (3X0.8X0.4 m) at 10±1°C with a natural photoperiod. Proper amount of carvacrol was sprayed on 1 kg of commercial trout diet to prepare four diets with 0 (Control, C0), 1 (C1), 3 (C3) and 5 (C5) carvacrol g/kg diet. Fish were fed to apparent satiation three times per day. The feeding trial lasted four weeks. Then, in different type of fish tissues (muscle, liver and pyloric caeca) from fish fed with diets enriched in carvacrol, beneficial elements (Cu, Mn and Zn) were analysed by atomic adsorption spectrophotometer. Results showed that the levels of Cu, Zn and Mn were especially significantly increase by C1 diet in all tissues (muscle, liver and pyloric caeca) except muscle and pyloric caeca Zn. The results of this experiment indicate that the carvacrol had the ability to potentiate the trace element retention. Although bioaccumulations of Cu, Zn and Mn in the muscle, liver and pyloric caeca are well demonstrated, the exact mechanisms of phytoadditives are still only partially understood. More investigations are required to detail the mechanisms involved in phytoadditives this enhancement

Effect of helicobacter pylori positivity and dyspepsia on depression and somatosensory amplification

Helicobacter pylori gastritis is an infection frequently observed around the world. In our research, the effect of Helicobacter pylori positivity on depression and somatosensory amplification was investigated. The research included a total of 112 patients with dyspeptic complaints, 52 Helicobacter pylori positive and 60 Helicobacter pylori negative, and a healthy control group of 54 cases without any complaints. Participants completed the Beck Depression Inventory and the Somatosensory Amplification Scale. There was no effect of Helicobacter pylori positivity on depression levels (p=0.116), while Helicobacter pylori positivity had a significant effect on somatosensory amplification (F=6.794; p=0.010; η2=0.40). There were significant effects of dyspeptic complaints on depression levels (F=6.695; p=0.011; η2=0.039) and somatosensory amplification (F=7.554; p=0.007; η2=0.044). It was identified that somatosensory amplification, sex and family history were each statistically significant explanatory variables for depression (p=0.001 β2=0.255; p=0.038 β2=0.150; p=0.002 β2=0.230). There was a 0.269 increase in depression for each 1-unit increase in somatosensory amplification, the female sex increased depression by 2.463 units and positive family history increased it by 4.949 units. Helicobacter pylori positivity was not found to be a significant explanatory variable for depression (p=0.412). While Helicobacter pylori positivity did not have an effect on depression, it was found to be effective in somatosensory amplification. The presence of dyspeptic complaints was effective on both depression and somatosensory amplification. Somatosensory amplification was one of the factors predicting depression in patients with dyspeptic complaints. Somatosensory amplification is an important factor in patients with Helicobacter pylori positivity and dyspeptic complaints. Mental diseases should not be ignored during the monitoring and treatment of this patient group. [Med-Science 2023; 12(4.000): 1088-93

Utilization to Remove Pb (II) Ions from Aqueous Environments Using Waste Fish Bones by Ion Exchange

Removal of lead (II) from aqueous solutions was studied by using pretreated fish bones as natural, cost-effective, waste sorbents. The effect of pH, contact time, temperature, and metal concentration on the adsorption capacities of the adsorbent was investigated. The maximum adsorption capacity for Pb (II) was found to be 323 mg/g at optimum conditions. The experiments showed that when pH increased, an increase in the adsorbed amount of metal of the fish bones was observed. The kinetic results of adsorption obeyed a pseudo second-order model. Freundlich and Langmuir isotherm models were applied to experimental equilibrium data of Pb (II) adsorption and the value of RL for Pb (II) was found to be 0.906. The thermodynamic parameters related to the adsorption process such as Ea, ΔG°, ΔH°, and ΔS° were calculated and Ea, ΔH°, and ΔS° were found to be 7.06, 46.01 kJ mol−1, and 0.141 kJ mol−1K−1 for Pb (III), respectively. ΔH° values (46.01 kJmol−1) showed that the adsorption mechanism was endothermic. Weber-Morris and Urano-Tachikawa diffusion models were also applied to the experimental equilibrium data. The fish bones were effectively used as sorbent for the removal of Pb (II) ions from aqueous solutions

Age and Growth of Red Porgy, Pagrus pagrus from the Island of Gökçeada, North Aegean Sea

The aim of this study was to describe the age, growth and relationships between otolith morphometry and fish length, weight and age of the red porgy, Pagrus pagrus. This study was carried out from the shores of Gizli liman to Kefalos Cape in the north of Gökçeada Island, between March and June 2018. The samples were collected at depths of 40-120 m by long lines. The 66 individuals obtained from red porgy ranged in total length (TL) from 13.5 to 50 cm. The calculated length– weight relationship was determined as W=0.016TL2.9653 (R2=0.98). Individual ages were macroscopically determined by counting the annuli of sagittal otoliths. Estimated ages ranged from 1–12 years. The von Bertalanffy growth curve was fitted to the age/total length data as follows: L∞=51.48 cm, K= 0.18 and t0=-0.27. The red porgy sagittal otolith length, width and mass were measured between 4.96–14.72 mm, 3.49–7.85 mm and 0.0199–0.2460 g, respectively. No significant differences in otolith morphometry were found between left and right otoliths. This study provides valuable data for the stock assessment of common pandora in the fishing grounds of Gökçeada Island located in the North Aegean Sea

Psychosexual Adaptation and Quality of Life After Hysterectomy

Psychosexual adaptation and quality of life after hysterectomy has been a subject of concern to women and gynecologists. By performing a hysterectomy, it is expected to treat abnormal bleeding, chronic pelvic pain and symptomatic myomas, and to improve health related general quality of life (QoL). Most controversy arises from the assertion that many hysterectomies are performed unnecessarily, although it has minor positive effects, the problems encountered after hysterectomy negatively affect QoL and psychosexual health problems may develop. The reported sexual problems after hysterectomy include dyspareunia related to vaginal shrinkage and decreased lubrication, low libido, and not experiencing orgasm. Studies show that the prevalence of sexual dysfunction among women who have undergone hysterectomy procedure varies depending on methodological factors. No consensus exists on whether hysterectomy causes sexual dysfunction. The aim of this study is to draw attention to the impact of hysterectomy on women's health and to discuss the related factors affecting psychosexual adaptation

Biosorption of Heavy Metal Ions from Aqueous Solutions by Nonliving Scenedesmus Quadricauda Biomass

In present study, biosorptions of lead (II), cadmium (II), cobalt (II) and chromium (III) ions from water were studied and dead algae biomass (Scenedesmus quadricauda Chodat) was used as natural and biological sorbents. The effects of pH, contact time and metal concentration on the biosorption capacity were investigated. The maximum biosorption capacities for Co (II), Cr (III), Cd (II) and Pb (II) were found to be 32.8, 20.3, 63.9 and 123.0 mg/g, respectively. The experiments showed that when pH increased, an increase in the biosorption capacity of the biomass was observed. Freundlich and Langmuir isotherm models were applied to experimental equilibrium data of metal ions adsorption and the value of RL for Co (II), Cr (III), Cd (II) and Pb (II) was found to be 0.639, 0.580, 0.915 and 0.949, respectively. The algae biomass was effectively used as a sorbent for removal of metal ions from aqueous solutions

REPRODUCTIVE HEALTH

Sexuality education is defined as a life-long process of acquiring information about individual's private life, sexual identity and relationships and a process of changing behavior. The most essential purpose of sexuality education is developing positive sexual behavior which include self-confidence, requires respectful approach to both oneself and anybody, free of sexual coercion and violence, having pleasurable and safe sexual experiences, planning to be parents. The other purpose of sexuality education is decreasing negative outcomes which include unintended pregnancy, sexual coercion, sexually transmitted diseases, and sexual dysfunctions. It is aimed that to provide developing positive sexual attitudes during individual's growing period by gaining sexual knowledge and skills to protect their sexual health at present and in the future. In this way it is possible to prevent adolescent pregnancy, abortions and sexually transmitted diseases. Sexuality education must be viewed within the framework in biological, socio-cultural, psychological and religional dimensions. Many teaching methods are tried to achieve these sexuality education purposes. A few of them are peer education, computer-based program, focus on changing behavior teaching models and integrating sexuality education to formal education
